Application filed August 12, 1912. Serial No. 714,547.

To all whom it may concern:

Be it known that I, Gnoncr. It. EVERSON, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and tate of Ohio, have invented new and useful Improvements in Massage-Machines, of which the following is a specification.

My invention relates to massage machines.

The objects of my invention are: 1. To afford a simple, practicaland inexpensive massage machine. 2. To afiord a simple, practical and inexpensive massage machine having a construction adapted to enable it to take on its driving or propelling power from some belt or wheel or some other machine, preferably from the belt or hand wheel of a sewing machine. I accomplish these objects by means of the mechanism disclosed in the following illustrations, of which:

Figure 1 is a side elevation of that portion of a sewing machine above the table thereof and a front elevation of my invention attached to the hand-wheel of said machine. Fig. 2 is a side elevation of the handwheel of a sewing machine and also of my invention connected-therewith. Fig. 3 is a cross-section of the drive-wheel E, taken on the line bb, the saddle-bearing and the friction wheel band or tire being eliminated. Fig. I is a side elevation of the saddle-bearing of my invention together with the drive wheel workin therein and the connecting portion of the massage tube in longitudinal section. Fig. 5 is a side view of the metal coupling connecting the massage brush with the flexible driving shaft. Fig. 6 is a side view of the flexible driving shaft together with the metal coupling attached to each end thereof. Fig. 7 is a longitudinal section of the handle end of the massage tube together with the parts immediately connected therewith. Fig. 8 is a plan view of the saddlebearing and drive wheel working therein together with the hand-wheel of a sewing machine, said hand-wheel having its upper portion cut away. Fig. 9 is a cross-section taken on the line a;a, Fig. 6.

Like reference characters represent like parts in all the figures.

In Fig. 1, A is the upper portion or sewing mechanism of a sewing machine. B is the hand-wheel thereof. C is the table thereof. D is the supporting tube of my invention. E is the drive wheel of my invention. F is the bearing-saddle thereof. G is the rubber tube through which passes the flexible driving shaft K, said tube connecting at one end with the hollow stud-coupling 16 over which the end of the tube passes, said tube connecting at its other end with the handle I-I into the end of which said tube passes with a tight fit. I is a massage applicator. 1 is the base plate of the supporting tube D.

In Fig. 2, the numerals 2 and 3 are the two leaves of a hinge held together by the connecting pin 4. 5 is a setscrew passing normally through the upper leaf of said hinge but abutting the lower leaf thereof and being thereby adapted to elevate the upper leaf thereof, the lower leaf of said hinge being screwed fast to the drop-leaf of the sewing machine table. The base plate 1 is riveted fast to the upper leaf 2 of said hinge. 6 is a flange extending laterally and integrally from the lower portion of the bearing saddle F, said flange having a down Ward-extending stud-coupling 7 which extends integrally from the lower surface of the free-end portion of said flange and passes into the upper end of the supporting tube D with a tight fit but at the same time admitting a free movement of said tube thereon. 8 is one of a pair of slots cut through the upper end of said tube and entirely through the mouth thereof, said slots being adapted to give flexibility to the upper end of said tube in receiving and working on said coupling-stud. 9 is the rigid shaft that passes through the opening 13 of the drive wheel E, to which shaft said drive wheel is made fast by means of a screw or rivet passing through the opening 14 in the hub of said wheel and the opening 15 in said shaft. 10 is a rubber band or tire fitting into the channel 11 of the drive-wheel E.

In Fig. 3, 11 indicates the channel in the drive wheel E. 12 is the hub of said wheel. 13 is the horizontal opening passing through said hub and adapted to receive shaft 9. it is an opening passing vertically through said hub and adapted to receive a rivet or screw which fastens said hub and wheel to the shaft 9 on which said wheel is mounted.

In Fig. 4, 16 is a hollow stud-coupling extending laterally and integrally from the outside surface of the upper-end portion of one of the sides of said saddle-bearing. Said stud-coupling is tapered slightly toward said terminates in a small opening axially alin r ing therewith and adapted to receive the shaft to which the drive wheel'E is attached.

In Fig. 5, J is a metal coupling adapted to connect the massage applicator with the flexible driving shaft K. 19 is a base plate of the outer end of said coupling. 27 is studs, preferably a pair, extending outwardly from the outer face of said baseplate and adapted to fit into recesses in the base of the massage applicator 1. 20 and 21 are in raised bearing surfaces of said coupling, and adapted thereby to reduce and minimize the friction of the outerend of the V handle H thereon.

In Fig. vb, K is a flexible driving shaft, made preferably of leather, and connecting at one of its ends with the coupling J and at the'otherwith the coupling 17. The coupling 17 has an opening in one end adapted to receive the end of the flexible shaft K and described above.

one in the other end adapted to receive the shaft 9, and has also a small opening passing transversely and axially through each end and adapted to receive small pins which fasten said coupling to each of its said members. 15 is a small opening passing transversely and axially through the shaft 9,. which opening is adapted to aline with the opening 14 in the hub 13 as 28 are fins, as to radial width beginning with nothing and increasing suitably in width as they proceed outwardly until they reach and connect integrally with the annular flange 29, said fins being adapted to cut their way into the handle H internally when said bearing sleeve is driven into the end of said handle as aforesaid and to prevent said handle from revolving on said sleeve. 24 is an opening passing transversely and axially through said sleeve-bearing and adapted to aline with the opening 23 in said handle and admit of oil passing into the bearing groove between said raised bearing surfaces 20 and 21 of the coupling J and thereby lubricate the bearing of said sleeve on said coupling in a way to greatly reduce the liability of said oil working out forwardly and spreading over the outer end of said handle, and the washer 30 which is riveted tightly onto the inner end of said coupling is adapted to prevent said oil from working out and spreading over the inner surface of said handle I and also .over said flexible driving shaft,'saidwasheris also adapted to confine and hold said sleeve on said coupling.

In Fig. 7, I is a massage applicator which is a special-cast rubber cup, the brim portion thereof extending outwardly. 25, a screw which, passing through an opening in the base of said applicator and into atapped" opening in the outer end of said coupling J,

is adapted to firmly bind said applicator to said coupling. between the head of said screw and the base of said applicator and adapted to enlarge the bearing surface of the head of said screw thereon. 29 IS an annular flange on the outer end of bearing-sleeve 18 and adapted to give a suitable finish to the outer end of said 26 is a washer intervening the supportingtube D, takes a plurality of positions of which 33 indicates one. This lateral movement of said wheel gives a wider range forthe applicator I and besides overcomes to a certain degree the liability of bending said rubber tube and said driving shaft incased thereby so abruptly near said wheel E as to check and stop the movement of said massage brush. This lateral movement of said wheelE also makes it possible to substitute a rigid driving shaft for said flexible driving shaft. 7 V

In Fig. 9, 18 is the bearing-sleeve adapted to be driven into the outer end of the handle.

H. 28 are fins extending radially and integrally from the outer surface ofsaid bearing-sleeve and adapted to cut their way into the inside surface of the outer end of handle H and thereby prevent said handle from working loose, revolving and rattling 'on c said bearing-sleeve.

It is to benoted, that my invention can be geared up and' connected with the belt of a machine, preferably a sewing machine, about 7 as well as with the hand-wheel of said sewing machine, the belt of said machine work-.

ing and traveling in said groove 11 of said wheel E. It is to be noted-also that a variety of massage devices may be easily and quickly V substituted for said applicator I. 7

Having described my invention by illustrations and in detail, I will now describe it as a working mechanism. The stitching mechanism only of the sewing machine havingbeen disconnected, the machine is operated 1n connection wlth my inventlonafter the same manner as 1t1s' operatedin'wlndlng a bobbin. By means of the set screw 5, the

drive wheel E can be given any degree of pressure against the hand-wheel B of the sewing machine. By means of friction between the aforesaid wheels, the wheel B communicates or transfers its power to Wheel E, which, in its turn, drives the flexible shaft Ii and the applicator I. The flexible shaft II, having reached the limit of its annular flexibility assumes a state of annular rigidity and revolves the applicator I. In operating my invention, the operator sets or stands, treadling the sewing machine when sitting with one or both feet and with one foot when standing. The handle H of my invention is grasped with either hand, and by means of the lateral movement of the saddle bearing F and the drive wheel E, the massage applicator I or other device substituted therefor is given a range sufficiently wide to reach any part of the body.

My invention, after the massage process is completed, can be detached from the sewing machine in either one of two ways: (1) by detaching the saddle-bearing F from the upper end of the supporting tube I); and (2) by removing the pin 4 and detaching every part of my invention above said pin. In either instance, the remaining portion of my invention is not in the way when the sewing machine is in use, and, besides, said remaining portion being attached to a dropleaf of the sewing machine table, can there by be let down and entirely out of the way when the sewing machine is not in use.

Having thus described my invention by illustrations, in detail and as a working mechanism, what I claim is 1. In a massage machine, a coupling having a washer riveted securely to one end and a base-plate cast solid to the other end and an annularly grooved body between these extremes, said base-plate having studs projecting outwardly therefrom, said coupling having also an opening in each end and of different diametrical sizes, the larger of the two being adapted to receive the end of a driving shaft, and the smaller of the two being adapted to receive a screw, said studs being adapted to fit into recesses in the base of a massage device.

2. In a massage machine, a coupling sleeve having an annular flange cast solid to one end and an oil hole in the body thereof, said flange being adapted to give a finish to the outer end of a handle into which said sleeve is driven, said oil hole being adapted to admit oil into the bearing of said sleeve on a coupling working therein, said sleeve having also fins projecting from, and eX- tending longitudinally along, the outer surface thereof, said fins being adapted to prevent the end of the handle into which said sleeve is driven from turning on said sleeve, said sleeve being adapted to afford a suitable bearing between the end of a handle and a coupling working therein.

3. A massage machine consisting of a hinge-like structure removably attached to any suitable point of another machine, adjustable means for suitably elevating and lowering the free leaf of said hinge-like structure, a tube mounted endwise and upriqhtly on and securely attached to the free leaf of said hinge-like structure, a saddlebearing mounted on said tube and adapted to oscillate laterally thereon, a shaft mounted on said saddle-bearing, a drive-wheel mounted on and securely attached to said shaft and a rim of any suitable wheel of said first mentioned machine.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
