MASSAGING INSTRUMENT.

EEGIXICATION forming part of Letters Patent No. 732,356, dated June 30, 1903.

Application filed February 4, 1903.v Serial No. 141,871. (No model.)

` To all whom t may concern.-

Be it known that LBENJAMIN E. JosnPH, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Massaging Instruments, of which the following is a specification.

The main object of my invention is to provide a simplified form of power-driven massaging instrument adapted for mechanically performing various operations which are useful for massaging treatments. I accomplish this object by the device shown in the accompanying drawings, in which- Figure 1 is a transverse section of a massaging instrument constructed according to my invention. Fig. 2 is a longitudinal section of the same along the line 2 2 of Fig. l.

In the construction shoWn the handle 3, of suitable form to be grasped by the hand of the operator, is rigidly connected to the middle part of a hollow shank 4, which extends transversely of the handle 3. A shaft 7 is journaled in the handle 3 and connected with a flexible shaft 5, through which rotation is communicated to the shaft 7 from a suitable motor. (Not shown in the drawings.) Acrankpin 6 is rigid on the inner end of the shaft 7 and is disposed eccentrically on the axis of said shaft, thus forming a crank for operating the mechanism Within the shank 4. The shank 4 is provided with an aperture 8 in its side opposite the end of the shaft 7 for theV purpose of permitting access to the interior of the shank 4. The aperture 8 is normally closed by a cap 9. One end of the shank 4 is closed by means of a plug 10, Within Which is mounted a cross-head 11. The crosshead 11 is slidable longitudinally of the shank 4, butis confined against transverse movement. The outer end of the cross-head 11 has a screw-threaded aperture 13 therein for the purpose of removably securing thereto a mas. saging-head 12 of any desirable form. The inner end of the cross-head 1l has a transverse slot 14 therein, Within which is seated one end of a pitman 15. The pitman 15 is pivotally connected to the cross-head 11 by the pivot 16, and the other end of the pitman 15 is mounted on the crank-pin 6. An arm shank 4, which is opposite to the cross-head 11, said shank being provided with a suitable aperture 18, e Within which the arm 1-7 is seated. The arm 17 is connected to the shank 4 by means of the pivot 19, Which is disposed in parallel relation to the shaft 7. The aperture 18 is closed by a cap 20, through Which the arm 17 extends and which also forms a sleeve for retaining the pivot 19 in position. The outer end of the arm 17 is also provided with a screw-threaded aperture 21,10 which a massaging-head 22 may be' removably secured. The inner end of the arm 17 is provided with a cylindrical recess 23, disposed longitudinally of said arm.A A pitman 24, titting therrecess 23, is seated therein and is longitudinally slidable along said recess, but confined against `lateral movement with respect to same. The pitman 24 is also journaled on the crank-pin 6.

The operation of the device shown is as follows: The shaft 5 is rotated by a suitable motor and imparts such rotation to the crankpin 6, causing the cross-head 11 to reciprocate longitudinally of the shank 4 through the action of the pitman 15. The arm 17 is simultaneously caused to reciprocate angularly on the pivot 19 through the action of the pitman 24.

It will be seen that some of the details of the construction shown may be altered Without departing from the spirit of my invention. I therefore do not confine myself to :such details except as hereinafter limited in VYthe claims.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A massaging instrument comprising a hollow' shank 5 a crank journaled in said shank on a transverse axis; a head mounted in one end of said shank and longitudinally slidable therein; a pitman pivotally connected to said crank and said headand adapted to cause said head to reciprocate longitudinally of said shank through the rotation of said crank; an arm pivotally mounted on a transverse axis in the other end of said shank;

a second pitman pivotally connected to said crank and suitably connected to said arm to cause same to reciprocate angularly on said d 17 is. pivotally mounted in the end of the r ICO pivotal axis; said arm and said cross-head being adapted to have massaging-heads secured thereto; and means for rotating said crank, substantially as described.

2. A massaging instrument comprising a shank; a crank jonrnaled in said shank on a transverse axis; an arm pivotally mounted on a transverse axis in one end of said shank and adapted to have a massaging-head secured thereto; a pitman connecting said crank with said arm, said pitman being connected with said arm so as to be relatively slidable longitudinallyr thereof but confined against movementlaterally thereof and adapted to cause said arm to reciprocate angular-1y on its pivotal axis; and means for rotating said crank, substantially as described.

3. A massaging instrument comprising a shank; a crank jonrnaled in said shank on a transverse axis; an arm pivotally mounted on a transverse axis in one end of said shank and adapted to have a massaging-head secured thereto; said arm having a longitudinal recess extending into the inner end of same; a pitman seated in said recess and longitudinally slidable therein, said pitman being connected with said crank and being confined against lateral movement in said recess and adapted to cause said arm to reciprocate angularly on its pivotal axis; and means for rotating said crank, substantially as described.

Sgned at Chicago this 31st day of January, 1903.
