PHILISHAVE BATTERY SHAVER, 1950's

Philishave was the brand name for the electric shavers manufactured by the Philips Domestic Appliances and Personal Care unit of Philips (in the U.S.A., the Norelco name is used instead). In recent years, Philips had extended the Philishave brand to include hair clippers, beard trimmers and beard shapers. Philips used the Philishave brand name for their shavers from 1939 to 2006.

The Philishave shaver was invented by Philips engineer Alexandre Horowitz, who used rotating cutters instead of the reciprocating cutters that had been used in previous electric shavers.

The shaver was introduced in 1939, though initial production was limited due to the outbreak of World War II (the production facility in Eindhoven, the Netherlands was overrun by the German Army in 1940).
After the war, a slightly improved version of the cigar-shaped single-head shaver was introduced. A more ergonomic egg-shaped single-head model was introduced in 1948 and was designed by US industrial designer Raymond Loewy. Global sales increased markedly after a double-head model was introduced in 1951.
The brand name Philishave was phased out in 2006.

RAYDO ELECTRIC HAIR BRUSH, 1930's

A small battery in the block is connected to wires on the brush used as the bristles. As the hair is combed the current from the battery passes through the scalp via the wires.

The instructions claim that the brush can stop baldness and grey hair from forming if the unit is used seven minutes in the morning and five minutes at night, every day.

It was not actually very effective. We think that this would be considered a Quackery item.

A1243

WHITES ELECTRIC HAIR BRUSH, 1920's

"Electricity gives life giving properties to the hair right down to the roots".

According to the instructions, one 3 volt battery can do all this?. Just switch the unit on and brush 5 minutes in the morning and 7 minutes at night. The bristles are sharp hard wire, it must have been very painful to use. We think it's another Quackery item.

ROLLS "VICEROY" RAZOR SHAVER, 1938

Rolls Razor Ltd. is probably best known because of its sets of safety razors with a sharpening device (1920's and later) and later its manually driven Viceroy Non-electric Dry Shaver (patent application filed 1937). In the 1940's and 1950's Rolls Razor also manufactured electric shavers.

Assuming good prospects on the electric shaver market, Rolls Razor opened a new factory in Hemel Hempstead, where it was one of the pioneers in a new industrial area. However, Rolls Razor announced that it was to close its factory because of mounting losses and fears of a world slump - it was going back 'home' to Cricklewood. The company sold the Hemel Hempstead site and land for expansion to Kodak. Kodacolor film was introduced in 1957 and all the colorfilm processing in the UK was to be carried out at the Hemel Hempstead plant.

CARBON ARC SUN RAY LAMP, 1950's

A Health Ray Sun Lamp that uses two Carbon rods connected to the mains via a cooking element, this acts as a safety load.

When the carbons touch they create an arc of light that is very high in Ultra Violet light, making it ideal for a sun lamp. This unit would not only produce lots of smoke but the rods would continually need adjusting, as they quickly deteriorate when in use and burn away.

GRAMOPHONE POSTCARDS, 1930's

In 1929 Raphael Tuck went into the business of producing Gramophone Record Postcards. The English monthly journal Musical Opinion and Music Trades Review had a regular column "Gramophone Gossip". The September 1929 issue contains the following: “Gramophone Record Postcards: Messrs. Raphael Tuck are responsible for an amusing and interesting innovation in the shape of gramophone record picture postcards. Measuring 3in., these discs play for one minute and cost 3d each. Several series are already available, and I have heard admirable demonstrations of "Auld Lang Syne", "Ye Banks and Braes", "Annie Laurie", "Bonnie Banks of Loch Lomond". Besides these songs there are orchestral records and cornet and saxophone solos. One immediate result of these postcards has been the installation of portable gramophones in the smaller stations to demonstrate them!“

STROVIOLS, ONE STRING FIDDLE, 1930's

The instrument on the right is made by the inventor Charles Stroh; on the left is a home made version using a cigar box.

The introduction of Gramophones spurred the idea that greater volume could be achieved by amplifying the sound of an instrument with a horn. Early buskers could not afford the horned version, let alone a real fiddle, so they made their own out of cigar or biscuit boxes.....

TOURNAPHONE/PATHE' GRAMOPHONE, 1906

Tournaphone/Pathe' Gramophone of 1906

This model of the Tournaphone was made in Germany under license before the First World War. Note:- these machines use a jewelled stylus not a needle.

The word gramophone was first used by Alexander Graham Bell when he developed a machine using flat records instead of cylinders, but the principle was the same as Edison's Hill and Dale method (stylus vibrates up and down). Emile Berliner, a German American, first produced flat records that vibrated the stylus from side to side (the opposite of Bell's design).

The Tournaphone was a design developed by 'PATHE' in 1906 and plays Hill and Dale records at 90 rpm starting from the inside moving to the outside. It was easily changed to play ordinary 78 rpm records by turning the sound box, and replacing the jewelled stylus with a needle. 78 rpm records continued till the 1950's, the museum demonstrates 78rpm records on several gramophones including the Tournaphone.

The HMV gramophone is a model 109.
of the late 1920's, this one probably 1930's.

This Model 109 was advertised in the company brochure of 1928-1929 The Oak Model costing £10-10-0d Mahogany costing £12-0-0d

HMV, His Masters Voice, a famous style Gramophone from before WW2 and used well into the 1960's. The original style dates from 1913.

78rpm records were still being played well into the 1960's. 78 rpm records are still available, this player can be demonstrated in the museum.

In 1899 'The Gramophone Company' the UK partner to the US Gramophone Co, run by Emile Berliner, purchased the Trademark 'His Masters Voice' using a painting by Francis Barraud showing 'Nipper' the dog listening to a Phonograph, this had to be altered at the Gramophone Company's request, to show one of Berliners Gramophones as the original had an Edison type Phonograph.

EDISON BELL MAGNETIC PICK UP CONVERSION, 1930's

Wireless was becoming more popular in the early 30's; mechanical gramophones had been around for much longer.

If the acoustic head of a Gramophone was removed and the round block with a pillar for a needle in this kit was mounted in its place, then plugged into the other section which had a 4 pin valve plug on it, the unit could be plugged into the socket on a wireless receiver that was reserved for the valve prior to the speaker valve. This would connect the new electrical pick up to the audio output stage of the receiver, thus using it as an amplifier.

"NIPPER" ADVERTISING TRADE MARK FOR HMV, 1940's

Nipper was born in 1884 in Bristol, England, and died in September 1895. It has been claimed by various sources that he was a Jack Russell Terrier, a Fox Terrier, a Rat Terrier, or an American Pit Bull Terrier. He was named Nipper because he tried to bite visitors in the leg.

In 1898, three years after Nipper’s death, his owner painted a picture of Nipper listening intently to a wind-up Edison-Bell cylinder phonograph. On February 11th 1899 he filed an application for copyright of his picture “Dog Looking At and Listening to a Phonograph.” Thinking the Edison-Bell Company might find it useful, he presented it to James E. Hough who (displaying the kind of thinking that would eventually doom the Edison Records company itself) promptly said, “Dogs don’t listen to phonographs”.

On May 31st 1899, Nippers owner went to the Maiden Lane offices of The Gramophone Company with the intention of borrowing a brass horn to replace the original black horn on the painting. Manager, William Barry Owen, suggested that if the artist replaced the entire machine with a Berliner disc gramophone, the Company would buy the painting. A modified form of the painting became the successful trademark of Victor and HMV records, HMV music stores, and RCA.

ULTRAZONE OZONE GENERATOR, 1922

Devices generating high levels of ozone, some of which use ionization, are used to sanitize and deodorize uninhabited buildings, rooms, ductwork, woodsheds, boats and other vehicles.

In the U.S., air purifiers emitting lower levels of ozone have been sold. This kind of air purifier is sometimes claimed to imitate nature's way of purifying the air without filters and to sanitize both it and household surfaces. The United States Environmental Protection Agency has declared that there is "evidence to show that at concentrations that do not exceed public health standards, ozone is not effective at removing many odor-causing chemicals or "viruses, bacteria, mold, or other biological pollutants." Furthermore, its report states that "results of some controlled studies show that concentrations of ozone considerably higher than these [human safety] standards are possible even when a user follows the manufacturer’s operating instructions."

The US government successfully sued one company in 1995, ordering it to stop repeating health claims without supporting scientific studies, if that is the case we think it should be classed as Quackery.

COPPER KETTLE, 1920's

A fine example of an early electric kettle made in the UK by Cimflex Conduits Ltd. Faster boiling was achieved by Swan in 1922, by placing the element in a metal tube, directly into the water chamber.

Most electric kettles of the 1920s and 1930s retained the traditional look of their non-electric ancestor, usually being made from copper with the option of nickel-plate or vitreous-enamel finish. Some lighter aluminium kettles were made in the 1930s and a few chrome-plated streamlined designs with Bakelite handles appeared in the late-1930s.

Bruce Hammond Collection

A1221

CHROME KETTLE, 1914

The electric kettle was a uniquely British product, owing its existence and development to the British habit of tea-drinking. An electric kettle was first made by Crompton and Co. in 1891 and all the earliest examples had the element in a separate dry chamber under the water, maintaining the 'fire under the water' layout of traditional boiling vessels. The separation of water from the element made the kettle inefficient and expensive to run.

The electric kettle was, with a few exceptions, a strictly functional object and seldom seen outside the kitchen, being regarded as a supplementary appliance to the electric cooker.

This electric kettle was made by Launders Fray & Clark of USA.

HAWKINS 'TECAL' TEAMAKER, 1952

The first Teamaker was made by Goblin in 1936, many similar types were made after this, the one shown was made by Hawkins in 1952.

The Teamaker was a British invention of the 1930’s and was developed by the British Vacuum Cleaner company ('Goblin') and first marketed in 1936.

Within a couple of years, similar early morning tea machines appeared, although all versions operated in the same way: the alarm on the clock was set and when reached, an electric element in the kettle was switched on to heat the water. The pressure of the boiling water made it decant through a tube in the kettle lid into an adjacent tea or coffee pot, making the whole unit pivot forward and activating the light and buzzer alarm. Thus the sleeper awoke to a freshly brewed pot of tea!

The 'Teasmade' was a prime example of the 'servant replacement' function of many electrical appliances, as it took on the task of the early morning maid, her first responsibility being to supply a welcome cup of tea. Some very lavish versions were produced on large trays, with matching teapots and crockery sets. The 'Teasmade' was one of the few gadgets of the period to have survived, creating its own market and developing into a recognised household appliance.
See item A1226 for the 1936 version.

REMINGTON STANDARD No 7 TYPEWRITTER, 1896

This machine has wooden keys and is poor condition but all the marks and transfers still remain. Its serial Number is 159,878 probably made in the early 1900's. The type is struck on the paper from underneath, so the typist cannot see what has been done, without raising the Carriage assembly. Later this method was abandoned due to pressure of competition to front typing where it can be seen. Remington was the first to make the under-typing model after purchasing the rights from the inventor Christopher Laythem Sholes in 1876, by 1882 the Name Remington was a name only, Wyckoff Seamans and Benedict were making them , and bought sole rights to make the machines 3 years later. This machine is in working order.

HOUSE OF PARLIAMENT DIVISION BELL, 1930's

Believed to be one of the bells connected to the Transmitter No2
(see Item No A0226) positioned in the Houses of Parliament, the transmitter was activated when it was necessary to call the M.P's to the house when a vote was needed.
The bells would be in all the bars and meeting places that the M.P's were likely to be, if a vote was imminent then the members were obliged not to stray far from a bell, usually no more than a mile away.
The local MP did say these were still to be seen in the House of Commons.

COMPTOMETER CALCULATOR, 1950's

The comptometer was invented by Dor Eugen Felt in the 1980's in America. Dorr E Felt started his first prototype during the Thanksgiving holidays of 1884. Because of his limited amount of money, he used a macaroni box for the outside box, and skewers, staples, and rubber bands for the mechanism inside. This prototype, called the macaroni box, is in the Smithsonian Institution in Washington, D.C. Units like the one shown were leased in large numbers by companies such as Sumloc Comptometer, who Purchased the rights in England in 1960, until electronic adding machines replaced them. See Item A1157. The machines worked by adding only and other functions were completed by progressive use of the keys.
Similar to the Sumlock machines leased by the bell Punch Company.
Not all Comptometers are of Bell Punch origin. Many were made and marketed by others, whether Bell Punch had there own manufacturing base for there machines is not clear. This model Model L.C. 912/SF/6069 of unknown manufacture could have been made in America and imported, then leased (as they usually were) by any number of companies.

This machine is Marked 'The London Computer Corporation'.

A0101

COMPTOMETER CALCULATOR 509/S, 1950's

This Model No 509/S/94.317 and models like this one were leased in large numbers by companies such as Sumloc Comptometer, until electronic adding machines replaced them. The machines worked by adding only and other functions were completed by progressive use of the keys, ladies often complained that the long strokes of pushing down the keys broke their finger nails. The curator of this museum used this model when she worked at Marks and Spencer in the 1960's and had the reputation of being the quickest operator in the office. The Plus and Sumlock are machines of the "Comptometer" type; the Sumlock being the full-keyboard version and the Plus the abbreviated-keyboard version. They are intended primarily for addition, but can also be used for subtraction, multiplication and division using learned techniques.
The main feature of this type of machine is that it has a full-keyboard and is "key driven", which means that pressing any key immediately adds the number on that key to the number displayed in that column, with carrying to the next column taking place where necessary.
The machine is designed so that keys in different columns can be pressed simultaneously. This means to add the cost of several identical items the operator arranges his or her fingers on the required keys and then depresses them all simultaneously the number of times for the number of items. Working in this way this type of machine is much faster than a 10-key type of machine where each digit has to be entered successively.
In 1960, the Bell Punch Company bought the British rights to the Comptometer design and trademark, and continued its development. In 1961, Sumlock, a division of the Bell Punch Company, was renamed The Sumlock Comptometer Ltd, and began marketing the first all-electronic desktop calculator, the ANITA Mark VII. The entire calculator division of the Bell Punch Company was bought by Rockwell International in 1973. Unfortunately they exited the calculator business in 1976 and shut down all operations.
Not all Comptometers are of Bell Punch origin. Many were made and marketed by others; whether Bell Punch had their own manufacturing base for these machines is not clear. See Item A1157.

GESTETNER DUPLICATOR, 1950's

At a young age Gestetner began to work at the stock market in Vienna. One of his tasks was to make copies of the stock market activity at the end of the day by copying the results over and over for each copy. He decided that there had to be a better method, and his experiments eventually led him to invent the first method of reproducing documents by use of a stencil.

DICTOGRAPH OFFICE INTERCOM, 1950's

When offices started to use the Dictograph, the main drawback of the system was the need to install extensive wiring, and businesses were reluctant to change to such an expensive system to replace their tried and tested speaking tubes. Lamson Engineering was a major worldwide provider of office equipment at this time, and added Dictograph to their range of products. The suggestion may have come from Lamsons that Dictograph should rent their systems rather than sell them outright, and spread the buyer's cost over many years. By 1908 Dictograph systems rented from as little as five dollars and fifty cents a month for one master console and five stations. It was not an original idea. Companies in England such as General Electric had already launched into the rental market in the late 1890s , and the New System Private Telephone Company began in the late 1890s as well. Telephone Rentals began in 1902.

DICTAPHONE RECORDING MACHINE AND CYLINDER, 1940's

Dictaphone was an American company, that produced sound recording devices most commonly used to record speech for later playback, or to be typed into print. The name "Dictaphone" is a trademark, but in some places it has also become a common way to refer to all such devices.

The name "Dictaphone" was trademarked by the Columbia Graphophone Company in 1907, they soon became the leading manufacturer of such devices.

After relying on wax cylinder recording through to the end of World War II, in 1947 Dictaphone introduced their Dictabelt technology, which cut a mechanical groove into a plastic belt instead of into a wax cylinder. This was later replaced by magnetic tape recording and eventually hard-drive recording.

ADANA PRINTING PRESS, 1950's

Production of the range of Adana machines was between 1935 and the 1950's, and the 'Adana Agency' was founded in 1922 in Twickenham by Donald Affleck Aspinall Adana. All the machines were destined for the amateur market.

Up to 30 sheets can be printed on these machines in one hour by an inexperienced operator, once the type has been placed and put onto the machine.

Type is held in place by a box frame called a 'Chase' using blank spacers called 'Quoins' to pack out the complete area. When printing rollers move up onto a round disk covered in ink which revolves slightly on every press of the handle. Once the ink is on the 'form' (the completed 'Chase') the bed holding the paper ('Platen') to be printed is pressed hard onto the 'Form' and then removed after the handle returns to its rest position.

The 85 refers to the size of the flat bed on which the type set is placed - 8 x 5 inch. This machine was made after 1953 and cost £16.80.

OPTIMUS MAGIC LANTERN, 1920's

The Magic Lantern or Lanterna Magica was the ancestor of the modern slide projector.
In the 19th century a thriving trade of projectionists traveled around the United Kingdom with their magic lanterns and a large number of slides to put on shows in towns and villages. Some of the slides came with special effects, by means of extra sections that could slide or rotate across the main plate. One of the most famous of these, very popular with children, was The Rat Swallower, where a series of rats would be seen leaping into a sleeping man's mouth. During the Napoleonic wars, a series was produced of a British ship's encounter with a French navy ship, ending patriotically with the French ship sinking in flames, accompanied by the cheers of the audience. The museum is able to demonstrate this Magic Lantern and is a great favorite with school children.

POLAROID "LAND" CAMERA, 1970's

There were a variety of models beginning in 1972 with the original SX-70, though all shared the same basic design. The first model, sold in Florida in late 1972, had a plain focusing screen (the user was expected to be able to see the difference between in- and out-of focus) because Dr. Land wanted to encourage photographers to think they were looking at the subject, rather than through a viewfinder. When many users complained that focusing was difficult, especially in dim light, Dr. Land was forced to include a split-image rangefinder prism of the kind used on 35mm SLR focusing screens. This feature is standard on the SX-70 Model 2.

KYOTO S600 8 TRACK STEREO PLAYER, 1980's

The original format for magnetic tape sound reproduction was reel-to-reel audio tape recording, first made widely available in the late 1940s. However, threading tape into the recorders was more difficult than simply putting a disc record onto a phonograph player. Manufacturers introduced a succession of cartridges which held the tape inside a metal or plastic housing to eliminate handling. The first was RCA Victor, which in 1958 introduced a cartridge system called Sound Tape or Magazine Cartridge Loading, but until the introduction of the Compact Cassette in 1963 and Stereo 8 in 1965, none were very successful.

WIRELESS LICENCE, 1930

The British Broadcasting Company Ltd was a British commercial company formed on 18 October 1922 by British and American electrical companies doing business in the United Kingdom and licensed by the British General Post Office.

On 31 December 1926, the company was dissolved and its assets were transferred to the non-commercial and Crown Chartered British Broadcasting Corporation.

The BBC had to be paid for by public subscription ie listeners were required an annual licence.
All manufactures were legally bound to obtain a licence from the Post Master General, before producing their Wireless Sets.

The licence shown was issued to Thomas George Morris Asquith 93 Vale of Heath Road, Port Tenarth, on the 15 of January 1930, Cost 10 Shillings.

KNIFE SWITCHES, 1940's

A selection of knife switches for general switching purposes.From the 1940's&50's
Single pole lever switches switches were often used to protect wireless units from lightning damage, and were commonly seen on window ledges during the 1950's and before.
Normally the lever is thrown to connect the aerial, when the operator is finished the lever is changed over to the other side, which is connected to earth. A direct strike would not protect very much as the voltage would be high enough not only damage the aerial but also anything in the proximity of the wiring, however a near strike would send all received voltages to ground.
In the case of Sheet lightning whole areas can be ionised causing the atmosphere to glow blue in colour, such strikes are generally dissipated and without the switch being set to ground certain damage would occur.
On some of the switches there is a spark gap in the On position, so that if the switch is not in the earth position some of the voltage can jump the gap.

KOLSTER-BRANDS "BLACK CAT" RECEIVER, 1932

Only 40,000 "Black Cat" wireless sets were made and were given away free in exchange for coupons from packets of cigarettes in 1930.

The cigarettes in question were "Best Dark Virginia", and in order to qualify for a free radio, it was necessary to spend over £12 which would have purchased 500 packets of ten.

At that time the price of receivers was very high, because of a protection scheme run by a cartel of British manufacturers.
The valves that were used had to be British, and the royalties had to be paid to the Marconi Company and the BBC.

The sale of cheap foreign imports was banned but giving them away "free" wasn't, so this loophole was exploited in order to sell more cigarettes.

The receivers were made by KB but cheap imported valves were supplied by the tobacco company.

The KB shown here is one of the earliest Bakelite-cased models and is an extremely neat design using a TRF circuit around a couple of 2-volt valves. The lid which carries the loudspeaker hinges up to reveal the tuning and reaction controls.
Unfortunately although the receiver is very small, the batteries were standard and had to be employed externally to the set.
This changed the neat receiver into a bit of a messy affair with its trailing leads and collection of batteries.

MOVING IRON LOUDSPEAKER, 1920's

Before permanent magnets were made strong enough and cheap enough, loudspeakers used a coil moving an iron reed which was attached to the diaphragm of the speaker.
Internally a high resistance coil with a permanent magnet through it was used to move an iron reed, attached to a rod on which was placed the paper cone. An Adjustment was provided for maximum efficiency. This method did not require a strong magnet to operate, and the quality was inferior to modern loudspeakers which use the moving coil principal.

Before permanent magnets were made strong enough and cheap enough, loudspeakers used a coil moving an iron reed which was attached to the diaphragm of the speaker.
Internally a high resistance coil with a permanent magnet through it, was used to move an iron reed, this was attached to a rod on which was placed the paper cone. An Adjustment was provided for maximum efficiency. This method did not require a strong magnet to operate, and the quality was inferior to modern loudspeakers which use the moving coil principal.

"THE THINKER" MOVING IRON LOUDSPEAKER, 1940's

Extension Loudspeaker for transferring the wireless to other rooms, with fret cut out to the shape of 'The Thinker' sculpture.

On the the rear view can be seen the adjustment control for the Moving Iron Loudspeaker, it was necessary to occasional correct the clearance of the reed or armature, to keep the unit working properly if this was not done loud volumes would cause thumping or sticking, the unit needed to be able to give good sensitivity for all volume levels.

RADIO MAGNAVOX MH1, 1920's

Designed to replace Headphones on early Wireless sets, before loudspeakers had been perfected because of problems with a strong enough magnet.
The coil is a high enough impedance to connect directly to the output valve of the set. The terminals on the units would carry high voltages, and yet no insulation was thought necessary.

RADIO LOUDSPEAKER HORNS, 1920's

A selection of loudspeaker horns from the 1920's and a Bakelite Philips Loudspeaker from the 1930's.

Including
A BTH Tpe C2 1925
An Amplion 'Standard Dragon' AR19 1923
A Telephones Le Las Horn 1920's
A Philips Lamps Ltd Bakelite Paper Coned Loudspeaker surround Model 2007 1928
The horns would replace headphones on early valve receivers before loudspeakers had been perfected, or even manufactured, and were simply connected directly to the audio amplifier valve in the receiver. They were normally high resistance and therefore very sensitive. The connection from the audio amplifier valve would carry high voltages; (not liked by today's health and safety regulations!)

McMICHAEL MAINS THREE RADIO, 1933

The McMichael Mains Three was a three valve TRF receiver that was built like a Tank. With a metal back and no expense spared on its construction in 1933 it cost 20 Guineas (£21).

The Mains Three is what is known as a 'landmark set', i.e. it introduced a significant or interesting feature into radio design. In this case, it was the first radio to have a dial calibrated directly in wavelength (metres) - up until then dials/knobs were 0-100 with a look-up table.

A high efficiency four valve circuit is employed, double gang tuned to indicate on the duplex scale (not fitted on this model). An automatic grid bias dispenses with a grid bias battery (grid bias required with this model) and automatically adjusts the reproducing valves to maintain unimpared tonal quality throughout the life of the high tension battery. The set is contained in a handsome case of dark furniture hide, fitted with ebonite panels and controls, with with nickelled panel fittings. For protection an aluminium valve screen is employed.

Made between 1928 and 1931 it cost around 17 Gns.

McMICHAEL CONSOLE RADIO MODEL135, 1935

The firm of McMichael Radio, based in Slough, was established in the early 1920s by Leslie McMichael, in collaboration with design engineer Ben Hesketh. (Until the late 30s, sets carried the initials M-H, which stood for McMichael-Hesketh.)

Their sets were very solidly engineered, and made to a high standard. The company went to a lot of trouble promoting the radios. Publicity was helped by demonstrations of their sets' abilities to receive on trains and aeroplanes. These tests were probably less severe than the public imagined, but they were good publicity stunts.

Their sets were sold mainly by accredited dealers, who were urged on by an in-house magazine called the McMichael Messenger, which featured dealers from around the country.
