Faradic Instruments

Voltamp (Wiki)must have made quite a number of the Faradic Medical Instruments since they show up a lot on eBay. Sears & Roebuck Co. and Montrogmery Wards Co. carried these or another brand in their catalogs. The common configuration is a wooden box that would hold 1, 2 or 3 No. 6 dry cells along with the induction coil and some wire leads with applicators for the body like metal cylinderes, plates or sponges. The Voltamp product introduced in 1901 is called a "Portable Electric Battery".

This company made model trains from 1903 to 1922 then sold that product line to Boucher Mfg Co (Wiki).
The small electric motor patents probably relate to the toy train products?
There were a number of different models of the Voltamp Portable Electric Battery where the models were numbered from No. 1.

No. 0 ?

I call it No. 0 since it clearly predates the No. 1 below. It does not have the brass or copper tube as part of the coil to regulate the secondary voltage so predates the 620027 Induction Coil patent issued, Feb 21,1899 (filed Dec 7, 1898. It's more than just a breadboard but does not include a box. The wiring method of using slots in the bottom of the board is identical to the No. 1 below (see Fig 2 and Fig 4 above)
There is a post anchored to the base board to hold the armature - spring - weight but in the No. 1 the post has been replaced by a bracket on the end of the coil. That would allow testing the coil prior to mounting it on the top board.


Right terminals are for battery	Left terminals are for battery VOLTAMP in lower right

This may have been a part of a boxed unit. A recent eBay add for a "Unusual Early Wet Battery Galvano-Faradic Quack Machine" has this descriptive text:

A great, early, walnut case (7 3/4 X 8 1/4 X 6 inches wide closed), quack medical machine made by the Galvano Faradic Mfg Co of New York. It originally had a wet battery in the case, now missing, for its power. It has its 2 hand electrodes but is missing the wires. Still, few of these could have survived, the wet cell battery is easy to spill and the acid would have eventually destroyed the machine. There is a little minor staining on the bottom of the case (from the acid) otherwise what is left is in great condition.

This coil contains the Fuld (Voltamp) patented sliding sleeve to control the strength of the output.

There is a board about this size that can be removed from the box (along with the battery selector switch board of similar size) to allow access to the wet battery.

No. 1

The label mentions the following patents by date:
D29977 Design for a Current Regulator Case, , Manes E. Fuld, Jan 10, 1899, D13/125 ; D8/DIG.2 - potentiometer for use with medical equipment
620027 Induction Coil, Manes E. Fuld, Feb 21,1899, 336/75 ; 336/196; 336/213; 336/219
627917 Dry Cell, Manes E. Fuld, June 27, 1899, 429/134 ; 429/171; 429/65
and shows a hand written serial number of 5375.

Included with this unit was a copy of "Electro-Medical Guide, formerly "Faradic Hints", ninth edition of 100,000. This 48 page booklet features the No. 6 "Majestic" on the rear cover. copyright 1916.

The top board and all the accessory electrodes have sockets that accept standard phone Tip pins. The wooden handled electrodes and the top board have tapered holes and the metal plate has the socket formed by a stamping operation.

Testing with a 1.5 volt "F" cell it does not run, but with two series cells ( 3 volts) it runs well. It may have been designed to run on a Voltamp brand 3 volt battery? If you know please tell me.

10 May 2008 - When two series connected "D" cells are used and the vibrator screw adjusted for loudest sound the frequency is around 800 Hz and the duty cycle around 80%. If the screw is backed out the frequency goes down along with the duty cycle. Around 300 Hz the duty cycle is near 50%. If at the 50% setting a 1.5 Volt battery is connected the vibrator does not self start, but if you flick the armature it will keep running.

No. 2

No. 3

No. 4

No. 5

No. 6 Voltamp Medical Battery No. 6 "Majestic"

The large metal cylinder is a Voltamp brand 3 Volt dry cell battery.
Guess: the large shiny cylinder is a battery similar to the No. 6 except it has a rectangular metal post in the top center with a screw for making electrical connection. You can see the screw and a slotted metal contact in the photo below.

No. 7

Except for the "No. 7" on the label, this looks identical to the No. 1.
If you know the difference please tell me.
