Referring to the drawings, wherein for the purpose of illustration is shown a preferred em- 10 bodiment of the invention, A generally designates: the frame of the machine embodying a horizontal platform 20 secured on four corner standards 21. Adjacent the lower ends the standards 21 are braced by horizontally disposed bars 22. To· 15 the lower end of each standard 21 is secured a swivel bracket 23 in which is rotatably mounted a carrier wheel 24, enabling convenient movement of the machine from place to place.

On a horizontal cross structure below the plat- 20 form is secured a drive motor 26 having a horizontally extending shaft 27 formed at the outer end with a crank 28. At the intermediate portion of the drive shaft 27 is fixed a grooved pulley wheel 29. Above the motor is journalled a hori- 25 zontal countershaft 30 having grooved pulley Wheels 31, 32 and 33 fixed thereon. At one side of the countershaft 30 is journalled a horizontal auxiliary shaft 34 having a grooved pulley wheel 35 fixed adjacent one end and having an eccen- 30 trie disc 36 fixed on the intermediate portion thereof. At the outer end of the· shaft 34 is secured a slide bracket 37 provided with a set screw adapted to adjustably hold in position a crank bar 38 slidably fitted in the bracket 37. 35 At one end of the crank bar 38 is rotatably secured a horizontally disposed handle 39.

At one side of the frame is journalled a vertical double grooved transmission wheel 41 driven through the medium of a belt 42 trained over one 40 groove in the periphery of this wheel and the grooved pulley wheel 33 on the countershaft. A belt 43 is trained over the relatively large pulley wheel 32 on the countershaft and the reduced pulley wheel 29 on the drive shaft to effect 45 the driving connection between the motor shaft and the countershaft. A belt 44 is trained over the relatively large wheel 35 of the shaft 34 and over the small pulley wheel 31 on the countershaft. go

In a pedestal bearing on the platform 20 at one side of the frame is journalled a vertically disposed drive wheel 46 arranged above the transmission wheel 41 and driven by a belt 47 trained over these·wheels. To the outer side of the wheel 55

2,139,166 is rigidly secured a diametrically disposed bar 48 having slidably fitted thereon a sleeve 49. Upon a stem extending horizontally outward from the sleeve 49 is supported a rotary gripping han5 die 50 adapted to be grasped by one hand of a patient receiving treatment for exercising the wrist and elbow. The fastening stem, indicated at 51, is threaded in the sleeve so that the latter may be secured in selected position on the bar 10 48 which is preferably formed with a graduated scale to designate various positions thereon. An arm rest 52, shown at Figure 11, and in dotted lines at Figure 1, may be removably connected with a bracket 53 on the frame so that the grip15 ping handle 50 may be engaged to revolve the hand for exercising the wrist or for exercising the elbow or shoulder.

To the pin of the crank 28 is connected the lower end of a vertical rod 55 extending through 20 an opening in the platform 20 and having its upper end pivotally connected with a horizontally disposed lever 56. On one end of the lever 56 is secured a padding sleeve 57 arranged adjacent an arm rest 58 on the platform. The opposite 25 end of the lever 56 is pivotally connected to an upstanding bar 59 having its lower end connected to a pivot bracket 60. On the bar 59 is slidably disposed a cross fitting 61 which may be secured in desired position by means of a screw 62. Pro30 jecting horizontally outward from the fitting 61 is a coiled spring extension 63 providing a resilient support for a padded ball 64 attached to the end and adapted to function as a knuckle vibrator. To the rod 55 is connected an angular bracket 65 35 embodying a vertically disposed depending support bar 66 carrying thereon an elongated channel-shaped holder 67 slidably engaging the bar and adapted to be fastened in selected position by a set screw 68. The holder channel 67 car40 ries thereon a corrugated pad 69 formed of rubber or the like and designed to provide an element for vibrating or striking lightly the back and spine of a patient. To the lower portion of the bar 66 is adjustably connected a bracket 70 45 formed with a U-shaped extension 71 and designed for treating the thigh and calf.

To one side edge of the platform 20 are secured a pair of parallel angularly depending bars 73 provided with transversely opposed apertures dis50 posed to receive therein a pivot pin 74. The pin 74 is slidable through a pair of pivot brackets 75 secured to the outer side of a foot board 76. At one side of the foot board is mounted a segmental graduated scale 77 for a purpose which will be 55 described hereinafter. Formed integral with and depending from the lower edge of the foot board 76 is a slotted member 78 disposed to engage an actuating pin 79. The pin 79 may be removably fitted in any one of a number of longitudinally 60 spaced apertures 80 formed in a rocker bar 81 which is rockable on a supporting shaft 82 attached to the frame. The inner end of the rocker bar is formed with a slotted extension 83 arranged to engage diametrically opposed edge por65 tions of the eccentric disc 36. Thus, revolution of the disc oscillates the rocker bar and causes swinging movement of the foot board 76. The arcuate movement of the foot board may be regulated by varying the position of the pin 79 on 70 the rocker bar 81, the movement of the foot board being readily ascertained by the scale 77. Thus, a patient seated on the platform, as shown at Figure 2, places his feet against the foot board 76 so that swinging movement of the board will 75 result in a beneficial exercise of the ankles.

To a side edge of the platform is hingedly connected an inclined outwardly projecting elongated leg support 85 having slidably fitted thereon a foot rest 86. To the underside of the foot rest 86 is connected a bracket 87 threadedly engaging 5 a longitudinally disposed screw 88 rotatable by a hand crank 89 to adjust position of the foot rest. Adjacent the upper portion, of the leg support 85 is mounted a segmental graduated scale 90 disposed to indicate the swinging movement of 10 the support.

To a web 92 formed on the pulley wheel 35 adjacent the periphery thereof is connected a laterally projecting threaded pivot member 93 formed at one end with a knurled head and sup- 15 porting a. sleeve 94 rotatable thereon. To the inner end of the sleeve is connected a cap 95 serrated at the edge and disposed to engage the serrated edge portion of an annular member 96. To the outer end portion of the sleeve 94 is con- 20 nected a crank arm 97 on which is slidably fitted a sleeve 98. As will be noted, the crank 97 together with the sleeve 94 may be rotatably adjusted relative to the wheel 35 by loosening the pin 93 and rotating the serrated cap 95 relative 25 to the fixed serrated member 96. A pivot pin 99 is connected to and extends laterally from the sliding sleeve 98. One end of a telescopic connecting rod 130 is pivotally connected to a bracket 181 secured to the lower end of the leg support 30 85. The opposite end of this rod is pivotally connected with the pivot pin 99.

A second connecting rod 102 is mounted so that one end is also pivotally connected with the pivot pin S9 while the other end rotatably engages the 35 intermediate portion of a crossbar 103 adjustably fitted upon an elongated frame constituting a pair of side bars 104 projecting through a slot in the platform 20 and having a swinging connection therewith through the medium of bearing 40 brackets i05 engaging a pivot shaft 106 attached to the platform. The upper ends of the side bars i04 project above the platform and carry thereon a transverse cross bar 107 which is mounted so as to enable longitudinal adjustment. Thus, rotary 45. operation of the wheel 35 results in similar operation of the crank arm 97 and the connecting rods 100 and 102, resulting in swinging movement of the leg support 85 for exercising the knees, and swinging movement of the frame bars 104. The _Sq patient engages the upper cross bar 107 so that, during swinging movement of the bars 104, body bending and exercising action is thus effected. A removable back rest 109 is mounted on the platform to support the patient during use of the leg 55 bending and knee exercising apparatus.

At one corner of the platform 20 is secured an upstanding standard 111 supporting a curved transverse support bar 112 thereon to the ends of which are connected a pair of coiled tension 60 springs 1 ί 3 having gripping handles 114 fastened to the lower end. This construction affords pulling exercises for the patient under treatment.

On the intermediate portion of the platform 20 is mounted a grip exercising appliance 116 em- 65 bodying a horizontally slidable bar 117 normally urged towards one end of the device by compression springs so as to provide a resilient grip exercising appliance.

Summing up, the apparatus of the invention 70 comprises a wheeled frame, a single central source of power mounted on a sub-frame, and an upper platform on which are mounted the exercising devices. The motive power is generally the electric motor 26, although hand-power is avail- 75

2,139,166 able as shown at 39 in the drawings. This motor drives a plurality of shafts having eccentric cams for oscillating a number of levers. The said levers, in turn, oscillate a leg bender, an ankle fi exerciser, a back bender and a wrist-bending device. Both the ankle and the leg benders are arranged on one edge of the platform so that the patient may conveniently sit thereon. In all cases, the amplitude of the oscillating movement 10 is closely adjustable so that the maximum movement permissible, in the case of crippled limbs, be consistently maintained, as well as improvements in the bending action of the treated limb. Finally, a short eccentric, directly on the motor 15 shaft, is provided to produce a rapid vibrationlike oscillation which is used for massaging the back and other limbs of the human body. All the above noted devices are passive exercisers, although active ones may be used, and are shown ²θ at 111 and 116, wherein the patient himself exercises against a given load such as provided by a spring.

Thus, it will be noted that the present machine provides a compact wheeled structure carrying “⁵ a number of exercising and vibrating appliances and includes mechanism whereby several of these appliances are effectively driven by a motor carried on the frame. This construction will enable 30 the device to be wheeled into various rooms of hospitals directly to the patient and will thus enable convenient application of kinesitheric treatments.

It is to be understood that the form of my in35 vention herein shown and described is to be taken as a preferred example of the same and that various changes as to the shape, size and arrangement of parts may be resorted to without depart ing from the spirit of the invention or the scope of the subjoined claims.
