Referring to the drawings, wherein for the purpose of illustration is shown a preferred ernbodiment of the invention, A generally designates; the frame. of the machine embodying a horizontal platform 2|) secured on four corner standards 2|. Adjacent the lower ends the standards 2| are braced by horizontally disposed bars 22. To the lower end of each standard 2| is secured a swivel bracket 23 in which is rotatably mounted a carrier wheel 24, enabling convenient movement ci the machine from place to place.

On a horizontal cross structure below the platform is secured a drive motor 26 having a horizontally extending shaft 21 formed at the outer end with a crank 28. At the intermediate portion of the drive shaft 21 is xed a grooved pulley wheel 29. Above the motor isl journalled a horizontal countershaft 30 having grooved pulley wheels 3|, 32 and 33 xed thereon. At one side of the countershaft 3|! is journalled a horizontal auxiliary shaft 34 having a grooved pulley wheel 35 fixed adjacent one end and having an eccentric disc 36 xed on the intermediate portion thereof. At the outer end of the shaft 34 is secured a slide bracket 31 provided with a set screw adapted to adjustably hold in position a crank bar 38 slidably iitted in the bracket 31. At one `end oi the crank bar 38 is rotatablyy secured a horizontally disposed handle 39.

At one side of the frame is journalled a vertical double grooved transmission wheel 4| driven through the medium of a belt 42 trained'over one 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 counter-shaft and the reduced pulley wheel 29 on the drive shatt to effect 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 3| on the countershaft.

In a pedestal bearing on the platform 20 at one side of the frame is journalled a vertically dis;- posed drive wheel 46 arranged abo-ve the transmission wheel 4| and driven by a belt 41 trained over thesegwheels. To the outer side of the wheel 46 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 handle 50 adapted to be grasped by one hand of a patient receiving treatment for exercising the wrist and elbow. The fastening stern, indicated at 5|, is threaded in the sleeve so that the latter may be secured in selected position on the bar 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 gripping 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 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 51 arranged adjacent an arm rest 58 on the platform. The opposite 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 6| which may be secured in desired position by means of a screw 62. Projecting horizontally outward from the fitting 6| 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 embodying a vertically disposed depending support bar 66 carrying thereon an elongated channel-shaped holder 61 slidably engaging the bar and adapted to be fastened in selected position by a set screw 68. The holder channel 61 carries 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 10 formed with a U-shaped extension 1| and designed for treating the thigh and calf.

To one side edge of the platform 20 are secured a pair of parallel angularly depending barsl 13 provided with transversely opposed apertures disposed to receive therein a pivot pin 14. The pin 14 is slidable through a pair of pivot brackets 15 secured to the outer side of a foot board 16. At one side of the foot board is mounted a segmental graduated scale 11 for a purpose which will be described hereinafter. Formed integral with and depending from the lower edge of the foot board 16 is a slotted member 18 disposed to engage an actuating pin 19. The pin 19 may beremovably fitted in any one of a number of longitudinally spaced apertures formed in a rocker bar 6| which is r'ockable 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 portions of the eccentric disc 36. Thus, revolution of the disc oscillates the rocker bar and causes swinging movement of the foot board 16. The arcuate movement of the foot board may be regulated by Varying the position of the pin 19 on Vthe rocker bar 8|, the movement of the foot board being readily ascertained by the scale 11. Thus, a patient seated on the platform, as shown at Figure 2, places his feet against the foot board 16 so that swinging movement of the board will result in a beneficial exercise of the ankles.

I'o 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 81 threadedly engaging 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 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 supporting 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.. nected a. crank arm 91 on which is slidably fitted a sleeve 98. As will be noted, the crank 91 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 to the fixed serrated member 96. A pivot pin 99 is connected to and extends laterally from the sliding sleeve S8. One end of a telescopic connecting rod |99 is pivotally connected to a bracket |0| secured to the lower end of the leg support 85. The opposite end of this rod is pivotally connected with the pivot pin 99.

A second connecting rod |02 is mounted so that one end is also pivotally connected with the pivot pin 99 while the other end rotatably engages the intermediate portion of a crossbar |03 adjustably fitted upon an elongated frame constituting a pair of side bars |04 projecting through a slot in the platform 20 and having a swinging connection therewith through the medium of bearing brackets |05 engaging a pivot shaft |06 attached to the platform. The upper ends of the side bars |04 project above the platform and carry thereon a transverse cross bar |01 which is mounted so as to enable longitudinal adjustment. Thus, rotary operation of the wheel 35 results in similar operation of the crank arm 91 and the connecting rods |00 and |02, resulting in swinging movement of the leg support 85 for exercising the knees, and swinging movement of the frame bars |04. The patient engages the upper cross bar |01 so that, during swinging movement of the bars |04, body bending and exercising action is thus effected. A removable back rest |09 is mounted on the platform to support the patient during use of the leg bending and knee exercising apparatus.

At one corner of the platform 20 is secured an upstanding standard supporting a curved transverse support bar |2 thereon to the ends of which are connected a pair of coiled tension springs I3 having gripping handles |4 fastened to the lower end. This construction affords pulling exercises for the patient under treatment.

On the intermediate portion of the platform 20 able as shown at 39 in the drawings. 'I'his 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 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 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. Fina11y,- a short eccentric, directly on the motor 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 at III and IIB, 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 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 the device to be wheeled intoy 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 invention 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 departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claimtl. A mechano-surgical apparatus, comprising a frame, carrier wheels supporting said frame, a platform at the top of the frame, a leg exerciser pivoted to one side edge of the platform, means to oscillate said eXerciser, an adjustable foot rest at the end of the exerciser, a downwardly inclined leg rest secured to the edge of the platform adjacent the leg eXerciser, a pivoted foot plate at the outer end of the leg rest, means for oscillating the said plate, means for selectively varying the amplitude of the oscillating movement of said foot plate, bars pivoted below the platform and extending therethrough adjacent the edge opposite to that of the leg exerciser, a cross bar joining said bars, means for selectively oscillating said bars, and mechanism under the platform for operatively actuating the oscillating devices from a common power source.
