' THERAPEUILIC VIBRATOR.

' Specification of Letters Patent.

Application filed August 19, 1909. Serial No. 513,692.

To all whom it may concern:

Be it known that I, EDWARD H. AMn'r, a citizen of the United States, residing at Redondo Beach, in the county .of Los Angeles and State of California, have in body by application thereto of vibrations.

similar to tone vibration.

. l The principle of this invention is the employment of a rapidly rotating unbalanced rotor in connection with an electric motor for applying the vibrations thereby produced to the body or part to be treated.

It is desirable to avoid transmitting the vibrations to surrounding objects, and in carrying out this invention provision is made whereby the vibrating apparatus will not set up vibrations in the structure of the building in which'it is contained.

An object of the invention is to provide a vibrator of cheap and simple construction devoid of reciprocating parts and which is capable of regulation to produce various tone vibrations as required.

The accompanying drawings illustrate the invention. I

' Figure 1 is a plan of a cot provided with this invention. Fig. 2 is a longitudinal sectional elevation of the cot shown in Fig. 1. Fig. 3 is a view of a vibrator that may be applied to said cot, to a chair, to a foot rest, a hand rest or any other device capable of transmitting the. vibrations to the body. A fragment of the cot and the means for attaching the vibrator thereto are shown. Fig. 4 is an enlarged sectional detail of the vibration insulator for the legs of the cot. Fig. 5 is a view of the bottom' of the insulator shown in Fig. 4.

The means to support the patient or subject to be operated upon may be a frame 1 of an ordinary spring cot, and said cot may be provided with an inclined head-rest 2. The cot and head-rest constitute a practical applicator for the treatment of the body in the instances illustrated in Figs. 1 and 2.

The cot bottom may be of any approved form or bottom for a cot, as woven wire springs, canvas or other material that will support the body. Or in case it is so de- .electric motor.

' sired, the cot bottom may be a board supported at its ends on the end cross-pieces 4 of the cot, on which is supported the wire screens 3, shown in Figs. 1 and 2. To the cot bottom, 3 is secured a vibration distributing frame 5, to which is fixed the bearing frame or bracket 6 of the vibrator. The vibration inducing rotary unbalanced weight 7 may be of any suitable shape and radius and may have a speed of 3,000'revolutions, more or less, per minute. In the form shown the unbalanced weight is fixed to the shaft 7 of the rotor 22 which is an The unbalanced weight may be made of any suitable strong material as iron, brass, steel, etc., capable of standing the strain. Its thickness and dimensions may be determined by the constructor and it may be of any suitable form.

The legs 8 of the cot are provided with vibration insulators 9, one for each leg and each insulator may consist of a rubber foot having a central stem 10 to seat in a socket 11 in the leg 8 and having a central concavity 12 to act as an air cushion, the rub- Weight of the occupant of the cot.

The distributing frame 5 may be attached to the cot bottom 3 by any suitable means, as bycla'niping devices, staples or clips 13, and a lever or prop 14 may be pivoted at 15 to the frame and adapted to be thrown up into vertical or down into horizontal position to connect or disconnect the headrest 2 from the vibrationdistributing frame. The use of the invention is not limited to a cot, but the vibrator may be applied to chairs, hand-rests, feet-rests,'and other ap- Patented Feb. 20, 1912.

pliances by which vibration may be applied to the human system or any definite thereof.

In practice to use the cot, shown in Fig. 1, the subject to be operated upon, may sit or lie upon the cot, and in the latter case, he may place his head or shoulders upon the head-rest 2, the rotor being caused to rotate at a high velocity. The vibration is set up in the vibration distributing frame 5, and by that is transmitted to the cot bottom, and the vibration may be made of any desired frequency, ranging from low to very high tonic vibration. The rotor may be driven from a few hundred to many thousand revolutions per minute. The

portion speed may be determined by the skilful op- 80 her being of such thickness as to sustain the erator, and the motor may be caused to run at any desired rate of speed by the usual manner of regulating or controlling speed i not attempted to be shown in the drawings.

The bearing frame 6 may be secured to thedistributer by any suitable means and may constitute the fixed base of a suspended electric motor. In Fig. 3 a clamp 16 is shown for attaching the bearing frame 6 which has a swivel stem 17 provided with an annular groove 18, and the clamp 16 .has a socket 19 in whichthe stem 17 is revolubly held by the set screw 20 that has acylindrical tip 21 in the groove to retain the stem 17 in the socket. In this form the plane of rotation, and consequently the direction of;

the vibratory waves may be changed by turning the frame 6 'on the swivel joint thus formed. The rotor 22 rotating freely in the swiveled case fi allows this to be readily done.

The vibratory frame 6 may be of various forms and the difierent kinds of frame will I some A therapeutic vibrator comprising a support for the human body or apart thereof, an intermediary vibration distributer, a shaft, an unbalanced rotor fixed on the shaft, a bearing frame for said rotor shaft connected with said intermediary means by swivel means, an electric motor having a portion thereof fixed to thebearing frame and a portion fixed to the shaft, the motor being thus swiveled and thus adapted to direct its rotation in differentv directions thereby to change the direction of vibration.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 11th day of August, 1909. EDWARD H. AMET.
