UNITED STATES STEPHEN D. SMITH, OF HERCULES, CALIFORNIA.
THERAPEUTIC ELECTRIC VIBRATOR.
Specification of Letters Patent.
Patented Mar. 29, 1921.
Application filed July 8, 1918. Serial No. 243,958.
To all whom it may concern:
Be it known that I, STEPHEN D. SMITH, citizen of the United States, residing at Hercules, in the county of Contra Costa, State of California, have-invented a new and useful Therapeutic Electric Vibrator, of which the following is a specification, in such full and clear terms as will enable those skilled in the art to construct and use the same. 7
This invention relates to an electric vibrator adapted to deliver a series of electric currentsto the terminals of an apparatus used for therapeutic purposes.
An object of the invention is to produce an extremely simple and compact apparatus capable of giving exceedingly eiiicient results because of the fact that the coil used is of such a high resistance as to use a very small amount of current, thereby making the life of the battery much longer than is possible where a low resistance coil is used. I Another object of the invention is to produce an apparatus of the character described with only a single coil instead of the ordinary primary and secondary coil, thereby reducing the number of connections required, lessening the work of making the coil and making the entire construction cheaper and simpler.
Another object of the invention is to produce an apparatus of the character de scribed in which the make-and-break points will not be seriously burned by the sparks produced, the body of the user acting as a condenser to prevent an excessively heavy spark at the movable contact.
Another object of the invention is to produce a device in which the current of the battery used passes through the body oi the user as well as the higher voltage current produced when the circuit through the coil is broken.
Another objectof the invention is to pr0- duce a vibrator in which the intensity of the induced current may be easily increased or diminished by the user, by increasing or decreasing the tension wlth which the movable contact is held against the fixed contact, thereby increasing or diminishing the number of breaks per minute.
Other objects of the invention will appear as the description proceeds.
An embodiment of the invention is shown in the drawings, in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.
Figure 1 is a longitudinal sectional view of the complete apparatus,
Fig. 2 is an end elevation of the complete apparatus looking from the left Fig. 1.
Fig. 3 is an end elevation of the complete apparatus looking from the Fig. l, and
Fig. 4 is a diagram of the wiring and arrangement of the'pole pieces.
The numeral 1 indicates a metallic shell which slides over a cylindrical insulating shell 2, a second shell 3 being placed on the other end of the shell 2. The insulating shell is secured to the metallic shell 3 by having a cut formed in said shell, the edges of which are bent over the insulating shell at 3 after which holes 3 are punched in the metallic shell adjacent the lips 3 to assist in holding the sleeves in a fixed position with respect thereto. Caps 4 and 5 close the opposite ends of the shells l and 3. The shell 3 has a slot 6 along which a button 7 may be moved to connect or disconnect the electric circuit as may be required.
The coil 8 consists of about 125 feet of No. 24 gage copper wire suitably insulated and wrapped with a sheet of insulating material 9, one portion of which, as shown at 10, is bent upwardly to prevent the metallic contact plate 11 from contacting with the core of the coil.
The contact plate 11 extends between two layers of the insulation entirely under the coil and it has a copper contact tip at 12 which extends transversely thereto.
The coil is secured to two side plate 13, 14, by means of a wire 15 wound around said plates and coil, and the plates are then suitably secured to the shell 3 at the outer end thereof.
Extending between the layers of insulation above the coil is a plate 16, which has ears 17,- 18, for the support of a pivot pin 19 carrying an iron armature 20. The ar I claim as new and desire to secure by Let-' mature 20 has a spring contact plate 21, with split points 22, 23 secured thereto, the latter contacts being positioned to contact at the will of the user with the contact 12, a rubber band or other spring 12 holding said contacts normally apart.
The plate 21 has a hook 2 1 and the shell 3 has a hook 25 thereover which hooks are connected with a rubber band or other spring 26, also connected with a hook 27 on the button 7 V The coil has a wire 28 connecting it with the plate 21, and a wire 29 connecting it with the inner metallic sleeve 30, which latter is inside the insulating sleeve and which has a spring contact plate 31. V
The battery is shown at 32 and it is of a well known type having a metallic outer casing and central pole 33. The outside of the battery connects with the spring 31 while its pole 33 contacts with the plate 11.
The diagram of the electrical connections is shown in Fig. 4: in which 8 indicatesthe coil, 32 the battery, 1 and 3 the metallic sleeves forming the handles for the user, 7 the slidable button for operating the device, and 21 the contact plate.
A wire 29 extends to the battery from which another wire 11 and contact 12 ex tend into proximity to the contact plate 21, spring 12 holdingsaid'plate normally disengaged from the contact 12. A wire 28 connects'the other end of the coil with the plate 21, while an extension 4: 1 of said wire connects with the handle 3, while a wire 4 connects with handle 1.7 The button '7 serves to pull the plate 21 against the contact 12, whereupon the armature immediately causes the contact to be broken, the result being ters Patent of the United States, is as follows:---[ 7 7 1. An electric vibrator comprising the combination of an insulating sleeve, a metallic sleeve secured on each end thereof, a
'coil within the insulating sleeve and secured thereto, an armature circuit breaker, a battery, means to increase or dlminlsh the pressure of said circuit breaker on the contact.
and electric circuits connected with said sleeves whereby the induced currents on the breaking of the coil circuit will be delivered to said metallic sleeves. 1
2. therapeutic electric vibrator comprising an insulating sleeve, metallic sleeves thereon at opposite ends thereof, a coil therein, a battery, connections with the battery and coil, an armature circuit breaker, manual means to bring the armature into connection with its contacts under a variable Jressure and electric circuits whereb 7 the'induced currents produced in the coil will be delivered to the metallic sleeves.
A therapeutic vibrator comprising the combination of an insulating sleeve, metallic sleeves on each end thereof, a coil therein, a battery, a circuit makingvibratable armature, a slidable button to bring said armature into connection with its contacts with a, variable pressure, electric clrcuits and contacts whereby the coil is energized through said armature and connections whereby the induced currents in said coil will be delivered to said metallic sleeves.
1. In a therapeutic electric vibrator an insulating shell, a metallic pole piece on each end thereof, a coil within the shell, a vibratory circuit breaking armature, a battery,
connections with the coil and battery, whereby the coil will be energized when the circuit is "closed at the vibratory circuit breaker, V

5. In a therapeutic electric vibrator an insulating shell, a coil therein, plates supporting said coil in a fixed position, a plate having contacts at opposite ends of the coil, a battery in contact with one end of said plate, sleeves at opposite ends of the insulating shell, a circuit making and breaking vibratory armature, manual means to close the contacts on said circuit breaker, and connections with said sleeves whereby the induced.
currents of said coil will be delivered therei to whenever the coil circuit is made or" broken' 7 V r 1 a 6. A, therapeutic electric vibrator com prising insulating shell, a coil therein, a plate extending from end to end ofthe coil, and'having a contact at each end thereof, a second plate secured to the coil and having projecting ears at the end of the coil, a vibratory armature pivotally supported in saidcars, a resilientlmeans to hold the ar mature against the coil, resilient means for causingtlie armature to engage one of the contacts on the first plate, metallic sleeves on the endsof the insulatingshell,-electrical connections whereby the induced currents of the coil due to the breakingfof the circuit therein will be delivered to said methe apparatus with-current. 1
