ATTORNEY LIL UNITED srnrns PATENT VIBRATOR FOR MASSAQE TREATMENT;

Specification of Letters Patent.

Fatented March 2?, 1995.

Application filed October 6,1904. Renewed June 19, 1905. Serial No. 268,045.

cation to the part to be treated and mounted on a suitable handle for manipulating it, and means are also provided for connecting the motor with a source of motive poweras an electric battery, compressed-air reservoir, or the likein a way to permit the instrument to be moved about for convenience in making the application to dilierent localities of the body or the patient. i

In th drawings, Figure 1 is a plan view of my improved vibrator constructed as anunbalanced electric motor, with a part of the inclosing case removed and with the battery in side elevation and also a diagram of the wire system. Fig. 2 is a longitudinal section showing the employment of an unbalanced compressed-air motor for producing the vibrations. f g

" In the electric apparatus, a represents an eleotromagnet, of which I) I) represent the pole-pieces, d an armature, e a commutator,

3 5 f and g'the exterior conducting-wires, h the brushes, t the battery-cells, j the switchwires, and 7c a switch for cutting in or out one" or more cells of the battery according as moderate or high speed is required.

To one side of the armature e an unbalancing -weight Z is radially applied" to impart quick lateral vibrations to the case, whereby a palpitating action may be brought to bear against the parts to be treated when the instrument is pressed sidewise against said parts, and ,the said instrunent is preferably provided with a handle m for convenience in such application, the wires f 9 running through said handle. The handle facilitates the vibrations as compared with the action of the motor proper when grasped in the hand without a handle, as will be readily understood but the instrument may be so used if desired.

To one side of the motorcase and at right angles to the line of the handle, or approximately so, a radially-projecting hammerpiece 18 applied in the form of a disk n or other shape, as may be preferred as appropriate to the subject under treatment, for impact on the. aforesaidparts. I

To facilitate interchange of hammenpieces of different forms and shapes, the application to the instrument is tobe made in any de sired attachable way as, for instance, by a projecting boss 0 applied to the side of the case and having 'a tapered socket that is radial to the armature with a correspondinglytapered stud p of the hammer-piece fitting the socket with a slight friction for temporarily retaining it.

In Fi 2 I re resent. a modification in which a ucketewli eel g is substituted for the motor-armature, said ,wheel having practi-- cally the same radially-placed unbalancingweight Z with inlet-passage r and exhaustpassages through the" handle for operating the said wheel by compressedair or other va or or fluid to be supplied from any suitab e' source through a flexible pipe or otherv connection.

it Will be seen that lightand handy, as well as very eiiicrent vibrating instruments of this character, may be supplied very cheaply. It

will also be seen that with the motor pivoted in opposite sides of the case with the hammer-piece rigidly attached to the case in the plane oi rotation and the handle attached to the case approximately at right angles to the hammer-piece, a simpler and less expensive and a more convenient machine for manipulatin is provided,

. l c not herein limit myself to the particular form or shape of the handle or hammer pieces or to the precise relation of the hammer-piece in use to the handle or to the prime mover or to'passing themeans for supplying power through the handle, as these may be varied without departing from the spirit of my invention. v i

I claim as my invention l. A vibrator for massage treatment, comprising a handle and case connected together and a hammer-piece fixed to the case exteriorly thereof, a' prime mover Within said case and a rotary unbalanced mernberactuated thereby m the plane of the hammerpiece tor effecting the vibration.

2. An unbalanced rotary motor, an inclosing case having the motor pivoted in oppositeqsides respectively, a hammer-piece attached tothe 'inclosing case, a handle, at:

zoo

tached to the case approximately at right angles to the hammer-piece and means for supplying power to the motor.

3. A vibrator for massage treatment con- 5 sisting of a rotary unbalanced electromagnetic armature, fixed pole-pieces, an inclos ing case for said armature and pole-pieces having said armature pivoted in opposite sides respectively, a hammerpiece fixedly 16 attached to the exterior of the case, ahandle attached to the case ap roximate'ly at right angles to the axial line 0 the motor and hammer-piece, and circuit-Wires to the motor-terminals.

4:. An unbalanced'rotary motor, an inclosing case having the motor pivoted in opposite sides respectively, a hammer-piece attached to the inclosing case in the plane of rotation of the motor, a handle attached to 20 the case approximately at right angles to the Witnessesi hammer iece and means for su plying power to t e motor through the hand e.

5. A vibrator for massage treatment, con sisting of a rotary unbalanced electromagnetic armature, fixed pole-pieces, an inclosingcase for said armature and pole-pieces having said armature pivoted in opposite sides respectively, a hammer-piece fixedly attached to the exterior of the case in the plane ofthe rotation of the armature, a handle attached to the case approximately at right angles to the axial line of the motor and hammer-piece, and circuit-Wire's arranged lengthwise through the handle.
