PULVELEC MEDICAL INDUCTION COIL, 1930's

Coil for medical use.
They work by two coils, one with a smaller number of turns but of greater size of wire, surrounded by another of much greater turns but of smaller diameter wire, inside the centre winding is a core of iron at the end of which is a piece of metal, attached to a make and break contact which interrupts the supply to the centre winding, exactly as in an electric bell.
The result is an transfer of power from the centre winding to the outer, with a proportional change in voltage to the number of turns, i.e from a small voltage you can create a very high voltage, but at much lower current.

THE ELECTROPOISE (Part of the Quackery Collection), 1910's

Hercules Sanche was the inventor of the Electropoise (shown) and the Oxydonor, both claiming to do the same thing.

The device was very simple, consisting of a chrome or nickel plated sealed metal cylinder. If opened the contents could be sand or carbon, or in most cases nothing at all. Cloth wrapped wires led from each end with a metal plate of copper or aluminium attached to the ends of the cylinder.

Users of diaduction (a word coined by Sanche to describe the so called benefits of oxygen being absorbed through the skin) placed the metal plates on their body with elastic bands and placed the cylinders in a bowl of water.

In 1915 the US Post Office prevented Dr Sanche’s gadgets from passing through the mail system, this did not stop his production of many Quackery items. He moved around the country avoiding prosecution for 33 years. In 1952 he was still operating in Florida.

LARGE 18 INCH INDUCTION COIL, or RUHMKORFF COIL, 1900's

Electromagnetic induction was discovered by Michael Faraday (1791-1867) in 1831. Nicolas Callan (1799-1864) invented the induction coil in 1836 . They were used for medical complaints such as skin disorders and to power X ray machines. Marconi used one for his transmitter system for the first transatlantic transmission from Poldhu in Cornwall.
The coil section of this unit measures 18 inches.
They work by two coils, one with a smaller number of turns but of greater size of wire, surrounded by another of much greater turns but of smaller diameter wire, inside the centre winding is a core of iron at the end of which is a piece of metal, attached to a make and break contact which interrupts the supply to the centre winding, exactly as in an electric bell. The result is a transfer of power from the centre winding to the outer, with a proportional change in voltage to the number of turns, i.e from a small voltage you can create a very high voltage, but at much lower current.
This coil was associated with the X-Ray tube A0198 and the Arsenic screen A0199

WW1 X-RAY TUBE

In 1895 the German physicist Wilhelm Conrad Rontgen (1845-1923) discovered X-rays. He called them “X” because their nature was then unknown. The nature of the rays was not understood until 1912 when another German physicist, Max von Laue (1879-1960), managed to diffract them through a lattice of crystal.

X-rays are electromagnetic waves which pass through material that is normally opaque to light. These waves have a very short wave-length. The discovery of X-rays immediately created a considerable stir. Rontgen became a national hero and was awarded the Nobel Prize for Physics in 1901.

The X-ray tube shown was used during the Great War, along with the Arsenic Plate, Item A0199. Using them the surgeon was able to detect where a bullet had penetrated, (usually in the head), many operations were successfully performed thanks to Rontgen's discovery.

WW1 ARSENIC X RAY PLATE

Arsenic is a natural soluble substance found in the soil, this can then be absorbed by plants thus making them poisonous.

An Englishman W.L.Bragg along with his father W.H.Bragg established X-ray Crystallography, (this discovery was made shortly after Max von Laue discovered X-ray diffraction). Arsenic was one of the crystals they used to diffract the wavelengths.

The part of the body to be X-rayed is placed between this plate and the X-ray tube, A0198. If a high voltage is applied to the tube from an Induction Coil, A0136, then an image of the bones appears on the arsenic plate.

WW1 K SCHALL CONTROL PANEL FOR ELECTROTHERAPY

This item was made by Siemans Bros at Woolwich, and is believed to be part of an Electric Shock Machine used during WW1. It would have been used in hospitals to treat the victims of “Shell Shock”.

Thousands of men fell victim to this debilitating disease- which had previously gone unrecognised. Sufferers were often accused of malingering or cowardice, it is almost certain that over 300 British servicemen were executed during WW1 who were suffering from Shell Shock and not cowardice. Today the condition is known as “post-traumatic stress disorder”

EVER READY MEDICAL COIL, 1954

This example was made in 1954, but similar items have been around since the 1930’s. It was used to treat skin conditions such as excema or 'exema' (sic), and dermatitis as well as other skin complaints.

The voltage was produced from small batteries which would be contained within the box, the patient would feel a tingling sensation when they passed the implements over the effected area.

This item can be compared with the modern day “TENS” machine

HODGKINSON HEALTH MACHINE, 1923

An electrotherapy device incorporating an induction coil. The coil creates medium voltages that are transmitted to the patient by two flat electrodes on the base.

Electrotherapy is a form of treatment whose basic aim, when used as a physical therapy, is to heal by stimulating activity in wasted or damaged muscles, and to promote healing by the increase of circulated blood in those areas. It can and has been used for the relief of pain, and for minor operations such as the removal of ulcers and cysts.

The Electro Neurotome Vibrator is another item using a form of Electrotherapy.

Galvanic current was "of low intensity, but of considerable quantity, and produces very considerable results on temperature, and very appreciable chemical results."

Faradic current, or "induced electricity" has almost no chemical action, almost no effect on temperature, causes no burning feeling, no sensation of heat, like that produced by the simple current from the battery; but it produces marked contraction of the muscles, and a powerful action on the nerves of both motion and sensation.

QUANTITATIVE SACCHAROMETER, 1892

Extract from "The Lancet" Dated January 16th 1892.

"Dr Edward Gans of Carlsbad has recently called the attention of the profession at Berlin to a simple instrument for the quantitive estimation of sugar in the urine, which is particularly adapted to the wants of the general practitioner, on account of its accuracy and ease of manipulation.

It consists of a U-shaped glass tube about six inches high, the longer leg of which is graduated as the annexed sketch shows, the shorter leg terminating in a glass bulb, on the extremity of which fits a glass stopper. The sides of the bulb of the stopper are pierced in corresponding diameters by two fine holes, so that the exit of air can be prevented by a slight turn of the latter.

To use the instrument, mix in the flask 10cc. of the urine to be examined with 90cc of clean water, and shake up with a piece of yeast the size of a coffee bean until there is no longer fragments of the yeast floating about in the vessel, then pour 10cc of this mixture into the bulb and adjust the stopper so that the holes in the bulb and stopper coincide. Now tilt the hole to the left so that the level of the fluid in the tube corresponds with the zero on the scale, and by a slight turn of the stopper shut of communication with the atmosphere. Leave the instrument in an ordinary room temperature (about 65 deg F) for eighteen to twenty four hours, and fermentation going on, the liquid in the tube will rise from the point 0 in proportion to the amount of sugar in the urine. The instrument is so graduated that the points on the scale correspond to the percentage of sugar, so that if the tube rises to 2.5 the percentage of sugar is 2.5.

After repeated experiments, Dr Gans found that the accuracy it almost equalled the method of polarisation, while in cases of the simultaneous presence of sugar and albumen in the urine it could be used when the polarimeter could not. (sic)"

Used for Electromagnetic Therapy, the Davis & Kidder Magneto-Electric machine is one of the more common quack devices.

Two rotating magnets that are in proximity cause the production of a current that can be transferred to the 'patient' through wires and metal handles. These machines were advertised to cure various nervous disorders and provided the user with a buzzing sensation that seemed to be effective.

A hand-held coil feeds radio energy into a low-pressure gas electrode. The energy is capacitively coupled into the human body, providing warmth via diathermy. At the same time, the gas discharge creates ozone and ultraviolet light, which were said to be effective in many skin diseases.

The equipment produced heat by diathermy, ozone and ultraviolet light.
