VIBBATING MACHINE.

Application filed April 10, 1925. Serial No. (l-2,263.

This invention relates to a vibrating machine that is used for massaging parts of the human body.

The objects of the invention are to provide a machine of the aforesaid class which stands on the floor and is conveniently adjustable to different positions so that various parts and members of the human body may be easily and comfortably presented to it for treatment; to provide a machine of the aforesaid character which administers a treatment identical with that known as the Swedish massage; to provide a machine of the foregoing nature that is capable of producing different speeds of the applicator to the end that the vigorousness of the manipulation or treatment may be varied according to requirements; and to provide a machine of the class above mentioned that is highly efficient, is very substantial, and is very durable.

The foregoing objects, with other and more specific ones hereinafter appearing, are attained in the construction illustrated in the accompanying drawings wherein Fig. 1 is a sectional side elevation of the machine; Fig. 2 is a rear end elevation; Fig. 3 is an enlarged transverse section through the upper portion of the machine, the plane of section being taken substantially on the line 33 of Fig. 1; Fig. 4 is a section on the line 44 of Fig. 1; and Fig. 5 is a sectional detail of the gear shift fork.

The machine consists of a comparatively heavy downwardly diverging base 1 that may be equipped with pads 2 of rubber or the like; and secured to the base, as by a central bolt 3, is a yoke 4. A gear casing 5 is supported within the upper end of the yoke 4 by trunnions 6 and 7 that are journaled, respectively, within the transverse bores of bosses Sand 9 wherewith the upper ends of the branches of the yoke 4 areprovided, the inner ends of the trunnions being reduced, as shown at 10, and inserted into sockets 11 in the sides of the gear casing 5 and secured therein by pins 12. The trunnion 7 is extended a considerable distance beyond the adjacent branch of the yoke 4 and is reduced in diameter and threaded, as shown at 15, and the hub of a hand wheel 16 is screwed upon the threaded extension of the trunnion. An anti-fricti on thrust bearing 17 is interposed between the inner end of the hand wheel hub and a shoulder 18 that is formed by the end wall of a shallow recess in the outer face of the boss 9 and which recess accommodates the bearing 17. By means of the hand wheel 16, the casing 5 may be clamped in any angular position with respect to the yoke 4 within the range of its pivotal movement. The outward movement of the hand wheel 16 is stopped by a washer 19 that is held to the end of the trunnion extension by a screw 20.

A housing occupies the casing 5 and the same is composed of circular end walls 26 and 27 and a curved wall 28 which connects the end walls (see Fig. 3). The end wall 26 closes the rear end of the casing 5, while the wall 27 occupies a cylindrical seat 29 that extends circumferentially about the interior of the casing. Screws 30 are extended through the peripheral portion of the end wall 26 and into the end of the casing 5 and serve to hold the housing in place. The housing is extended rearwardly beyond the wall 26 in the form of a shell 31 into which the forward end of the casing of a motor 32 fits. The motor is held to the shell 31 by screws 33 which have their inner ends threaded into internal lugs 34 of the shell.

The motor shaft 35 extends to the forward part of the housing 25 where it is journaled within a standard 36 that rises from the bottom of the housing. intermediate its ends the shaft 35 bears in a bushing 37 and at its rear end said bushing is enlarged and recessed to receive a packingwasher 38 that is held within the recess by a plate 39. The motor shaft 35 has secured to it gears 40, 41 and 42 which are adapted, respectively, to mesh with gears 43, 44 and 45 that are carried by a sleeve 46 slidably mounted upon a counter shaft 47 that is journaled at its opposite ends in the end walls 26 and 27 The latter gears are keyed to the sleeve 46 and at the same time held against rotation with respect to the shaft 47 by keys 48 that extend through keyways in the sleeve and enter a spline 49 in the shaft. The shaft 47 is equipped with a collar 50 at its rear end and at its forward end carries a disk 51 having a crank pin 51 to which is connected, through a suitable anti-friction bearing 53, a head 54 that is fastened to the rear end of a shaft 55.

This shaft is supported adjacent its forward end in a bearing 56 which is of the same nature as the bearing 53, the present bearing being fitted within the forward end of an extension 57 of the gear casing 5. The

shaft is held from rotating by a pin that occupies a notch 61 in a transverse wall 62 of the extension 57. A sleeve nut 65 is threaded onto the forward end of the extension 57 and clamps the flanged inner end of a shell 66, and the outer member of the anti-friction bearing 56, in place. A. cap 67 is secured, as by nuts 68, to the protruding end of the shaft 55 and carries a packing ring 69 that bears against the spherical forward end of the shell The inner member of the anti-friction bearing 56 is held in place through a spacer 70 that is interposed between said member and the cap 67. A packing element 71 fills the recessed forward end of the extension 57 inwardly of the antifriction bearing 56 and an annular plate T2 separates said hearing from the packing element.

From the manner above described of mounting the shaft 55 it will be readily seen thatwhen the counter shaft 4;? is rotated it will impart a wobbling action to the shaft 55 the lat er shaft being held against rotation by the pin 60, the bearings and 56 being of such nature as will permit wobbling of the shaft 55.

Secured, as by a clamping head 7 5, to the forward extremity of the shaft is a bell shaped applicator 76 which is constructed of rubber or the like. Different kinds of a pplicators may be substituted for the one shown, depending upon the purpose for which the same is to be used. The one illus trated may be employed for treating the chest, the abdornemthe arms, leg and shoulders. For the spine, a different type of applicator may be employed, and the same is true with respect to the low r limbs and feet, in the latter case stirrup or socketlike devices being employed and in which the foot may rest. These constitute no part of the present invention and illustration is therefore deemed unnecessary.

It may be explained that in the use of the machine, the casing 5 is clamped to the yoke 4 by means of the hand wheel. 16 in the position which best adapts the machine to the particular part of the body that is to be treated. When operating on the chest, shoulders, or arms, the front end of the easing 5 is inclined upwardly so that the person, standing on the floor on which the machine rests, may lean against the applicator. The applicator is placed about waist high for abdominal or hip treatments. It is lowered to a point adjacent the floor for treatments of the lower limbs, as well as when using the stirrup like applicator in which the foot rests, the person sitting while taking such treatments. ll'orinally, with the hand wheel 16 relaxed, the forward end of the easing 5 is held elevated by the weight of the motor 31. A. bumper 77 of rubber or the like is set within the crotch of the yoke 4 to receive the motor as it swings downwardly thereby to prevent the metal parts from striking together.

It will be understoou from the construction already described that the applicator travels in an orbital path of comparatively .nall radius; and it may be explained that its movement is at a comparatively high rate of speed. This speed, however, is changeable by the shifting of the gears previously referred to by means which I shall now describe.

Fitted within a circular opening 80 in the top of the gear casing 5 is the reduced inner end of a member 81 that is secured to the casing by screws 82. Journaled within a central aperture of the member 81 is a shaft 83 to the reduced upper end of which is fas tened, as by a pin 84:, a handle A disk 86 is secured to the reduced lower end of the shaft 83 and the same is adapted to he rotated by the handle 85. The disk 86 is restrained in three different positions with respect to the member 81 by a ball 87 that occupies a recess 88 in the member 81 and is depressed by a spring 89 that is confined between the ball and the top wall of the recess, the ball 8'? l'ieing adapted to occupy any one of three depressions 90 in the disk86. Rotatably connected to the disk 86 by means of a pin 91 (Fig. is a fork which embraces the top portion of the gear and through Wl'iiCli the gear is free to move during its rotation. By rotating the handle the sleevecarrying the gears L3, 44 and may he slid, through the intervention of the fork and the gear 43, aiong the shaft 47 so to disengage gear 43 from the gear 40 and engage either gear l-l: or wi h the 4:1 or 4.2, respectively. Obviously, the base of the handle and the peripheral portion of the member 81 may bear marks cooperating to indicate the gear positions. In order to quickly and conveniently align the teeth of the gears they are being thrown into mesh by the handle 85, the gears on the motor shaft 35 may be rotated by means of a hand wheel 95 that is secured to the rear end of the motor shaft. A fan 96 is applied to the motor shaft inside the shell 31, and said shell is provided with ventilating open- 7. A quantity of oil'may becontained within the casing 5 and fiow from end to end thereof as the casing is tilted so to lubricate all bearings within the casing, the oil being prevented from flowing to the motor compartment by the packing washer 238 and from leaking through the front of the e 1- tension 5'? by the packing element 71.
