nrrnn STATES WILLIAM GENTRY SHELTON, OF CHICAGO, ILLINOIS.

MASSAGE INSTRUMENT.

To all whom it may concern:

Be it known that 1, WILLIAM GENTRY SnELToN, a citizen of the United States, ibrmerly residing at the city of St. Louis, in the State of Missouri, and now residing at the city of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Massage Instrument, of which the followingnis such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accomplanying drawings, forming part of this specication.

- My invention relates more particularly to a massage-machine resembling that shown and described in Patents No. 816,506, granted to me March 27, 1906", and No. 829,742, granted to me August 28, 1906, and has for its object to provide improved means for adjusting the operating connections between the rotary member and vibrating contact device of such machines.

Referring to the drawings, in which like characters of reference indicate similar parts in the different views, Figure 1 is a side elevation of a machine embodying the preferred form of my invention. Fig. 2 is an enlarged vertical cross-section showing some of the parts in detail. Fig-3 is a vertical cross-section through the operating mechanism. Figs. 4 and 5 are respectively a vertical cross-section and a side elevation of a slightly-modified form of my improvement, and Fig; 6 is a vertical cross-section on the line 6 6 of Fig. '4, and .Fig. 7 is an enlarged detailed view of one of the parts.

The casing or frame of the machine is composed of two parts .10 and 11,. to the former of which the handle 12 is attached. To the handle 12 leads the conductor 14, which conveys the current by which the device is driven. The "

parts

10 and 11 of the casing are held together by means of screws 15. In

the part 11 is a journal-bearinglT'and in the partlO a journal-bearing 18." In these bear- The bearing 18 is suitabl ings a shaft 19 is mounted and carries the armature 20 of the electric motor.

' 21 is a circuit-breaker controlling the current supplied to the motor.

24 is a flywheel fastened'u on the shaft 19, which is journaled in the ushing 25 in the bearing 18 by means of. a set-screw 26. supported from the casing 11 by means of ms 27. The fiywheel 24 is provided with an inclined radial Specification of Letters Patent.

slot 29, having an opening at its side. In this slot 29 is pivotally and slidingly journaled a ball 31, rotatably mounted on the bar 32 by means of a sleeve33, thusiforming a pivotal connection between the bar 32 and fly-wheel 24.? Through the sleeve 33 passes a screwthreaded pin 34, which enters the end of the bar 32 and forms a swiveled connection between the ball 31 and the bar 32. The opposite end of the bar 32 carries the contactpiece 35. It is also provided with a ball 36. The outer end-37 of the part 10 of the casing is-screw-threaded and has screwed into it a screw-threaded member 38 as best. shown in Figs. 2 and 3. This member 38 is provided with a contracted portion 39 and an enlar ed portion 40. A second enlarged portion at the opposite side of the contracted portion 39 contains the ball 36, provided with a pin 42,

which projects into a slot 43 in the outer end of the member 38. Upon the outer end. of the member 38 is a milled nut 45, rigidly fastened thereon by means of a set-screw 46. This nut holds in place a rawhide bearing 47 for the ball 36, a brass washer 48 being interposed between the two parts. The opening in the outer end 37 of the casing is made adjustable by being provided witha slot 50,

clamped with a set-screw. 51 in lugs 52 at.

each side of the slot. 2

53 is a lock-nut threaded upon the outer end of the member 38 and adapted to abut against the shoulder formed by the end 37 of the casing.

Referring now to the modification shown in Figs. 4, 5, and 6, it will be-seen that the bar 32 is also provided with a contact device 35 and a ball 36. In this case, however, the

lower end 37 of the casing is sleeved about a cylindrical member or extension 56. In the outer end 37 of the casing is a slot 57, part of which is inclined, as best shown in Fig. 5.

Passing around the end of the casing is a ring 58, rovided with

lugs

59 and 60. Between the

lhgs

59 and 60 is a member 61, carrying a pin 62, which passes through the slot 57 and into an opening 63 in the tube 56. The

lugs

59 and, 60 are provided with a thumb-screw 64.- The member 56, which practically forms an extension of the lower end of the casing 37, is also provided with a bushing 65, which forms a part of the bearing for the ball 36.. The other part of this bearing is formed by a washer 66, held in place by a coil-spring 67, which abuts against a head 68, screwthreaded upon the outer end of the part 56.

The washer 66 and the bushing are provided with cut-away portions 69 and 70, which register with one another to form an opening into which the pin 71 on the ball 36 projects. I

In the operation of my invention it is evident that the rotation of the motor-armature 20 will cause a vibratory movement of the contact device 35, and it is evident that by 0 eratin the devices above described to c ange t e osition of either of the

members

38 or 56, W .ich practically form extensions of the lower part of the casing 37 to move the contact device 35 toward and away from the fly-wheel 24, the amount of the vibration imparted to the contact device 35 may be varied as desired, this operationresulting in radially changing the position of the bal 31 in the slot 29. When the proper amount of vibration has been secured, the parts may be fastened firmly in position in the form shown in Figs. 1, 2, and 3 by means of a lock-nut 53 and in the form shown in Figs. 4, 5, and 6 by means of the thumb-screw 64. The operation of the device has been more fully described in my rior applications above set forth, and is tlierefore not more fully referred to here.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
