DEVICE FOR THE APPLICATION OF ELECTROTHEBAYY.
AppIicatlon filed November 29, 1926. Serial No. 151,355.
This invention relates to improvements in apparatus for applying the principles of electro-therapeutics in the treatment of disease in the human system, especially in connection with the application of current electricity.
The present invention'is particularly deour co-pending application for patent, filed Nov. 20, 1926, Serial No. 149,599 to provide the mechanical means for creating the current interruptions in a certain fixed ratio' per minute, as 1s necessary 1n connectlon' with the method disclosed in that application.
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.
. These objects We accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.
In the drawings similar characters "of reference indicate corresponding parts in the several views:
Fig. 1 is a perspective view of the complete apparatus.
Fig. 2 is a diagrammatic outline of the electrical circuits employed in the apparatus.
Fig. 3 is a face view of a modified arrangement of the clock face and distributor.
Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates a container of any desired shape or form. A cord or conductor 2 may lead from a source of electrical energy and eXtends into the container 1 and connects with a transformer 3 which reduces the current to a low voltage and a low amperage.
A motive power 4:, preferably a clock with a second hand and dial 5 is mounted in the container 1. A distributor 6 having any arbitrary number-preferably seventy-two spaced and insulated contact points 7 is likewise fitted intothe container 1. A switch blade 8 is mounted for movement over the points 7 and is connected in driving relation with the second hand spindle 5 by means of gears 9 and 10 and a chain ll (or by an other desired power transmission elements so that the switch blade 8 will move at the same speed as the second hand so that in ,7 are wired in series to a wire leading through the switch 16' to the vibrator arm 17 of the vibrating coil 26. Wires 18 and 19 lead from the terminals of the secondary winding 20 of the vibrating coil to terminals 21 and 22. Instrumentalities 23 and 24 are provided to be held by or applied to the patient. One of these may be connected with either of the terminals 21 or 22, and
the other to a terminal 25 connected by a wire 14 with the primary winding of the vibrating coil. When the switch 16 is closed the apparatus is charged and with the rotation of the switch blade 8 under the influence of the clock motor there are seventytwodistinct vibrations delivered at the instrumentalities 23 and 24 into the body of the patient. Due to the transformer 3 and coil 1320,-this is mild and of low voltage and amperage.
It will be readily seen that by the use of our improved apparatus the current inter ruptions may be timed or synchronated to any arbitrarily fixed number per minute, thus giving us a mechanical apparatus admirably adapted for use in the carrying out of the method referred to in the second.
paragraph of this specification.
In the modification shown in Fig. 3, the usual clock face or dial is omitted, and its place taken by an enlarged seconds-dial 27, graduated in sixty parts and having a hand dial 28 pointing to the graduations. Mounted concentric with and behind the dial 27 is a larger interrupter dial 29, on
which the seventy-two contacts 7 are mounted as in the other type. The contact engaging switch-arm 8 is mounted direct on the second-hand shaft 5'. This arran ement condenses and simplifies the device, y eliminating a number of parts and rendering the device more compact. It also has a psychological effect on the patient, since the relationship between the sixty seconds and the seventy-two interruptions is made more apparent.
From the foregoing description it will be readily seen that we have produced such a device as substantially fulfills the objects of the invention as set forth herein.
While this specification sets forth in detail, the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claim.
Having thus described our invention what we claim as new and useful and desire to secure by Letters Patent is:
'the primary circuit, a vibrating inductance coil in the secondary circuit of the transformer, and' an interruptor switch interposed in such secondary circuit to provide fixed current interruptions through the inductance coil, and service terminals in the secondary circuit of the inductance coil.
In testimony whereof we afiix our signatures.
