SPECIFICATION forming part of Letters latent No. 725,987, dated. April 21, 1903.

Application-filed July 8,1902. Serial No. 114,765. (No model.)

To all whom it may concern:

Be it known that I, CHARLES OWENS, a resident of Chattanooga, in the cou'nty of Hamilton, State of Tennessee, have invented an Improved Massage Instrument, of which the following is a specification.

This invention is more particularly a vibrator for use in massageand manicure operations; and it consists, primarily, in providing improved mechanism having an adjustable stroke. 4

The nature and characteristic features of the invention will more fully appear by reference to the following description and the accompanying drawings in illustration thereof, of which Figure 1 is a side elevation of the improvements. Fig.- 2 is a front elevation thereof, and Fig. 3 shows the details of the fulcrum mechanism.

As shown in the drawings, the revoluble flexible shaft'l has the crank-disk 2, with the eccentric-pin 3 fixed thereto, the pin being connected with the block a, which is reciprocated thereby. The block 4 reciprocates in a slot or guide 5', formed in an arm 5, and

rocks the arm with relation to an adjustablefulcrum. The fulcrum mechanism comprises the not 6 and the flange 7, coacting with the bearing 7 which is adjustable in the slot 5, provlding an adjustable fulcrum-point for the arm 5 and regulating the reciprocation of the massaging or manicuring instrument connected at the point 5" thereof.

holding the flange 9" against ,thejihanger l0, and the bearing 9, having the shoulder 9, against movement from the position to which it may be adjusted in the slot 10 of the hanger, this mechanism being held on the bearing 7" bythe collar 11, having the setscrew 12. In adjusting the fulcrum mechanism in the slots 5 and 10 to the position required for efiecting the desired stroke the arm 5 is supported by a pin or boss 13 in the hangerhead 10, which lies in the circular slot or yoke 14 of the arm.

The handle 15 acts as a coupler between the flexible shaft-casting 16 and the hanger-head The fulcrum 1 mechanism further comprises the bearing or. shank 7 on which there is mounted the screw-threaded sleeve 8, having the nut Sfor 10, as well as a meansfor manipulating the instrument, and the hanger-head having a face-plate 17, secured in place by the screws 18 and 19, provides a casing for the driving mechanism.

It will now be evident that the stroke of the arm, which is oscillated by the revoluble shaft through its eccentric connection therewith, may be varied at will by means of the movable fulcrum, which may be fixed at any desired point along the respective guides of the hanger and arm, while the flexible character of the driving-shaft permits the operator to freely manipulate the instrument.

Having described my invention, I claim- 1. In a vibrator, a flexible revoluble shaft, an arm having a variable movement, a fulcrum having an adjustable relation to said arm, and mechanism through which said shaft actuates said arm, substantially as specified. 2. In a vibrator, a flexible revoluble shaft, and an oscillating arm connected with said shaft so as to be operated thereby, said arm having an adjustable fulcrum providing an adjustable stroke, substantially as specified.

3. In a vibrator, a revoluble shaft, an oscillatingarm, an eccentric connection between said shaft and arm, and an adjustable fulcrum for said arm, substantially as specified.

4. In a vibrator, a flexible shaft having a revoluble movement, an oscillating arm having an adjustable fulcrum, and an eccentric connection between said shaft and arm, substantially as specified.

5. Ina vibrator, a revoluble shaft,:an oscillating arm, mechanism by which said shaft actuates said arm, and a fulcrum for said arm adjustable with relation to the connection between said arm aud shaft, substantially as specified.

6. In a vibrator, a hanger, a shaft revoluble with relation to said hanger, an oscillating arm, mechanism by which said shaft actuates said arm, and a fulcrum for said. arm adjustable with relation thereto and to said hanger,substantially as specified;

7. In a vibrator, a hanger having a slot or guide therein, a vibrating arm having a slot or guide therein, mechanism for fulcruming said arm on said hanger, said fulcrum being adjustable along said slots or guides and guide and boss controlling said arm,substan-' to adapted to be fixed at the desired points tially as specified.

thereof, a revoluble shaft, and mechanism In testimony whereof I have hereunto set by which said shaftaetuates said arm, submy hand, in the presence of the subscribing 5 stantially as specified. Witnesses, this 5th day of July, 1902.
