Application October 11, 1944, Serial No. 558,152

3 Claims. 1

Thi invention relates to therapeutic devices and more particularly to therapeutic oscillation devices.

The primary object of the invention is the provision of a manually-portable oscillation applicator provided with means for applying oscillations to parts of the face or head or other comparatively small areas of the body and provided also with means for applying oscillations over-larger areas of the body.

The above and other objects, features and advantages of the invention will best be understood from the following description considered in connection with the accompanying illustrative drawings.

In the drawings:

Fig. 1 is a longitudinal view, partly in elevation and partly in section of an oscillation applicator embodying the present invention;

Figs. 2 and 3 are views of the opposite ends, respectively, thereof;

Fig. 4 is a longitudinal view thereof showing th applicator held at one end thereof for the application of oscillations by its opposite end;

Fig. 5 is a transvers sectional view on the line 5-5 of Fig. 1;

Fig. 6 is a sectional view of the resilient part of the head at one end of the oscillator; and

Fig. '7 is a detail view of the attachment of the weight to the motor shaft eccentrically thereof.

Referring now to the drawings in detail, the oscillation applicator Ill embodying the present invention is manually portable and is of such size and shape as to facilitate the handling thereof by the user. More specifically, said applicator is of such size and shape that it can be conveniently held at either end thereof in the users hand while the opposite end is brought into engagement with the desired part of the face, head or other part of the users body for applying oscillations.

The oscillation applicator ill comprises a longitudinally extending cylindrical or tubular frame I2 within which there is mounted an electrical motor [4 in fixed relation to said frame. More specifically, said motor I4 is carried by frame members It fastened to tubular frame I2 by brackets l'l secured to members It and 12 by screws l8 and I9, respectively, or in any other suitable way. The rotary shaft 26 of motor M is disposed co-axially of frame member 12 and is provided with a radially extending arm 22 having a weight 24 secured thereto. As shown in Fig. 7 arm 22 is secured to shaft 20 by a set screw 25. Thus the motor shaft 29 carries a weight eccentrically thereof, said weight being rotated by said shaft when the motor is operated.

Oscillation applying heads 26 and 28 are fixedly secured to the opposite ends, respectively, of tubular frame member 52. The oscillation head 2'5 preferably comprises a resilient pad 29 which is fixed to and thereby carried by the outer end of a rod 3% which is fixed to a disk secured in and closing one end of tubular frame member 42 by screws or in any other suitable way. Rod 3% and disk 32 are preferably formed in one piece of wood or other suitable material. Said disk has an outer end portion 35 on which is mounted a switch 38 for controlling the circuit of the electrical motor i l. An electric cord 49 for connecting the motor [4 to a source of electric for operating motor It passes through an opening 42 in disk Said disk is also provided with an opening it for the passage of air into the tubular frame l2.

The oscillation applying head comprises a reduced, inner end portion which projects into frame member l2 and is secured thereto by screws 43 or in any other suitable way. Head 8 is formed of wood or any other suitable material. Said head is provided with a recess 50 and with a plurality of openings 52 which extends from the outer surface of said head to said recess. The inner end of recess 553 is in communication with the interior of tubular fram member 52. Thus air can pass through openings t l and, 52 into and through tubular frame member 2 for cooling motor I l. It will be noted that spaces 55 (Fig. 5) are provided between motor-mounting members E5 to allow the passage of air through the tubular member I2.

It will be observed that the oscillation applying heads 26 and 28 which are carried by tubularframe member !2 at the opposite ends thereof, respectively, are disposed in line with the axis of rotation of shaft 28. Accordingly, when shaft 20 is rotated the cocentrically disposed weight 24 produces circular oscillations which are communicated to said heads and which cause the latter to osoillatate in directions running transversely of the axis of shaft 26. In the use of the device, the latter is held by the user at one or the other end thereof (Fig. 4) depending upon which head is to be engaged with the desired part of the users or patients head or body. More specifically, when the oscillation applying head 25 is utilized the applicator If) is grasped atthe opposite end, as illustrated in Fig. l, so that the oscillation of head 28 is arrested while the head 23 is free to oscillate under the action of the weighted shaft 20. On the other hand, when the head 28 is to be used for applying oscillations, the applicator i is held at the end thereof opposite said head 28 so that oscillation of said held end is arrested while head 28 is free to oscillate. It will be noted that motor is is positioned closer to one end of frame l2 than to the opposite end thereof so that the amplitude of oscillation of the head 28 which is fixed to the end of the frame which is farther from the motor is greater than the amplitude of oscillation of the other head which is fixed to the opposite end of the frame, which is nearer to the motor, when the frame is manually gripped adjacent one of said heads for the transmission of oscillations by the other of said heads. Ordinarily, the head 2t is utilized for applying therapeutic oscillations to parts of the face or head or to comparatively-small areas of the users or patients body while the head 28 is utilized for applying therapeutic oscillations to or over larger areas of the body. Further, it will be observed that head 25 being resilient provides for the application of oscillations to regions, for example, the eyes of the patient which require more gentle treatment, while oscillation applying head 23 being non-resilient can be utilized where less gentle treatment is desirable or applicable. The oscillation of the applicator frame is indi cated diagrammatically in Fig. 4 by the dotted line 56.

While I have shown and described the preferred embodiment of my invention, it will be understood that the latter may be embodied otherwise than as herein shown or described and that various changes in the embodiment herein disclosed may be made Without departing from the invention Within the scope of the appended claims.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

1. A manually portable oscillation applicator, comprising a tubular cylindrical member, motormounting means disposed within said tubular member between its opposite ends and fixed thereto, a motor fixedly mounted on said means and having a rotary shaft disposed co -axially of said tubular member, said motor being positively secured in said frame against movement axially of the frame, a weight carried by said shaft eccentrically thereof and rotatable thereby, an oscillation applying head fixed to one end of said tubular member and closing said end thereof, an oscillation head fixed to and closing the opposite end of said tubular member and provided with a rod disposed co-axially of tubular member externally thereof and an oscillation-applying member carried by the outer end of said rod, said motor being member and closing said end thereof, an oscillapositioned nearer to one end of said frame than to the other end of said frame whereby the amplitude of oscillation of one of said heads is greater than the amplitude of oscillation of the other of said heads when the frame is manually gripped adjacent one of said heads for the transmission of oscillations by the other of said heads.
