ALFRED J. STECKER, 013 DETROIT, MICHIGAN, ASSIGNOB, TO EUREKA VIBBATOR CO., OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

VIBRATOR.

To all whom it may concern:

Be it known that I, ALFRED J. STEOKER, a citizen of the United States, residing at Detroit, in the county of ayne and State of Michigan, have invented certain new and useful Improvements in Vibrators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a vibrator for massaging purposes, and consists in the construction and arrangement of parts hereinafter more fully set forth and pointed out particularly in the claims.

The object of the invention is to provide simple and efficient means for causing a vibration or gyration of the applicator, wherein the arrangement is such as to permit the vibratory movement to be regulated at will, so as to afford by a simple adjustment, any degree of vibration desired. It has been found that in vibrators of this class, a variation of the vibratory movement is absolutely essential so as to enable the degree of vibration to be regulated accordingly as the point of application is changed or the conditions vary it being essential that the means of adjustment be convenient and easily operatable that the desired variations in the vibratory movement may be readily made.

The above object is attained in the manner desired by the mechanism illustrated in the accompanying drawings, in which Figure 1 is an elevation of a vibrator embodying my invention. Fig. 2 is an enlarged detail in longitudinal section through the front end of the case, and through the parts which impart vibratory movement to the applicator, showing the means for adjusting said parts to regulate the vibration. Fig. 3 is a similar view, showing the position of parts when adjusted to afford the maximum vibration. Fig. 4 is a fragmentary view in elevation with parts in section, showing the construction of the ball and socket joint at the end of the case, the means for preventing the rotation of the ball while allowing said ball to tilt or rock in its confining bearings.

SerialNo. 429,134.

Referring to the characters of reference, 1 designates a suitable case or supporting frame mounted on a handle 2. Within the case or frame is a suitable electric motor indicated at 3 in Fig. 3, from which extends the motor shaft 4. Secured to the end of the shaft and rotatable therewith is a socket member 5 having a socket 6 therein which is inclined with respect to the axis of said member, the outer end of said socket being eccentric to said axis, and the inner end concentric thereto. Within the outer end of the case is a spherical member or ball 7 which is-seated in and confined between two hemispherical shells 8 and 9 respectively which embrace said ball, the inner shell 9 being seated in the opening in the end of the case, and the outer shell 8 being engaged by the gland 10 which screws onto the end of said case to confine and retain said parts. By adjusting said gland, any desired tension may be placed upon the members forming the ball and socket joint, and by means of the set screw 11 shown in Fig. 1, when adjusted, said gland may be locked.

Passing centrally through the ball and through the hemispherical shells which embrace it and which are provided with openings for that purpose, is a longitudinally reciprocatory rod 12 which is externally threaded, as shown at 13, and is provided at its extreme outer end with a threaded socket member let into which is screwed the stem 15 of the applicator 16, which is herein shown in the form of a rubber cup, but the form and character of which may be varied at pleasure. The rod 12 passes freely through the ball 7 and upon its inner end is provided with a rotary ball 17 which is adapted to lie in the socket 6 of the member or coupling 5 on the end of the motor shaft 4. Secured to the rod 12 near its inner end is a collar 18, and confined between said collar and the ball 7 is a compressible spring 19. Screwed onto the threaded portion 13 of the rod 12 is an adjusting disk 20 by a rotation of which the rod 12 may be adjusted longitudinally, causing the ball 17 on the inner end thereof to slide within the socket 6 of the rotary member 5. To limit the longitudinal movement of the rod 12 througli the ball 7, said rod is provided with a key-seat 21 therein (see Fig. 2), into which extends the inner end of the pin 22 which is fixed in the ball 7 and whose outer end lies in a slot.

, porting frame, a rotary member journaled ment of said rod with said rotary member.

23 formed in the end of the case, as clearly shown in Fig. 4. The presence of .said pin 22 in the channel or key-seat in the rod 12, limits the longitudinal movement of said rod, while the outer end of said pin lying in the slot in the end of the case, prevents a rotary movement of said rod and of the ball 7, the size of said slot 23 however, being such as to permit of the tilting or rocking movement of said ball.

When the parts are in the position shown in Fig. 2, a rotation of the shaft 4 and coupling member 5, will impart no vibratory movement to the applicator 16, because of the fact that the axis of the rod 12 which imparts movement to said applicator is in alinement with the axis of the shaft 4. By turning the adjusting disk 20, however, so as to screw the rod 12 through the ball 7 against the action of the spring 19, the ball 17 on the inner end of said rod will be drawn outwardly in the inclined slot 16 so as to cause the longitudinal axis of the actuating rod 12 to stand at an angle to the axis of the shaft 4, as clearly shown in Fig. 3, thereby imparting, as the shaft 4 revolves, a gymtory movement to the applicator 16 attached to the outer end of said rod 12. By turning the disk 20 in the opposite direction, the force of the spring 19 will draw the rod inwardly, causing the ball 17 on the inner end thereof to enter the socket in the rotary member 5, and as said ball gradually ap proaches the axis of rotation of shaft 4, the degree of vibration applied to the applicator 16 will be correspondingly reduced. By this simple arrangement, the gyrator movement imparted to the applicator may be regulated so as to render the vibration as light or as severe as desired, the arrangement being such as to enable the degree of vibration to be readily varied while the instrument is in operation. It will be understood that when the rod 12 is out of alinement with the axis of the shaft 4, a rotation of said shaft will cause the inner end of said rod to describe a circle about the axis of said shaft to accommodate which movement the ball 7 will rock or tilt in its confining shells.
