2 Claims.

to reshape the foot, as for instance, aclub foot,

and stretch the ligaments and tissue surrounding the bones in order that the operator may return the bones to normal position.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a side elevation of orthopedic apparatus constructed in accordance with the in- Vention.

Figure 2 is a fragmentary top plan view of the apparatus shown in Figure 1.

Figure 3 is a longitudinal sectional view through the compresssion jaws andshowing the means for adjusting the same.

Figure 4 is an end elevation of the parts shown in Figure 3.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, I l! designates a main frame preferably formed of angle iron, the same having angle iron legs H. A seat frame designated in general by the numeral [2 is supported by the legs above the top of the main frame, as best shown in Figure 1. A seat I3 is supported by the seat frame and an inclined back rest 14 50 is pivotally mounted as shown at IE on the seat and is adjustably mounted torock in any desired. angular position with respect to the seat, there being a slotted segment l6 carried by the seat and a set screw 11 carried by the back rest to permit of this adjustment.

A pair of jaws I8 and I9, shown best in Figure 3, is supported upon the front legs of the main frame by angle iron brackets 20 and by rods 2|, best shown in Figures 1 and 2. The jaws are hollow casings each provided in the top with a padded concave depression 22 to receive the free leg of the patient when one of the legs is being operated upon. The jaws are provided in their confronting inner side walls with concave depressions 23 which are provided with respective pads 24 that are pivoted at one end to the bottom of the depression. At the free end each pad is swivelly connected to a screw 25 which is screw threadedly engaged through a bracket 26, best shown in Figure 3. The screws project beyond the outer end walls of the jaws and each are provided with a respective button 21. By turning the screws manually the pads may be enclosed upon the patients foot for compression purposes during the corrective treatment.

One of the jaws is provided with a bracket 28 and a shaft 29 is swivelly passed through the bracket and is equipped on opposite sides of the bracket with stop collars 30. The shaft projects through the outer end wall of one of the jaws and is equipped with a crank handle 3| for rotating the shaft. The shaft passes loosely through openings 32 formed in the inner confronting end walls of the jaws and is screw threaidedly engaged in an opening 33 formed in the beforementioned bracket 26. The shaft forms means for moving the jaws endwise relatively to each other to properly position the jaws for compressing the foot while the free leg is supported in one of the padded depressions 22. By referring now to Figure 1 it will be seen that back of each jaw a stationary rod 34 is secured at its ends in one of the legs II and in an angle iron bracket 35. A rod 36 is slidably passed through a bracket 31 which depends from the top wall of the jaw at the depression 22. The

rear end of the rod is provided with an eye 38 which encircles the rod 34. The front end of the rod is equipped with a wing nut 39, best shown in Figures 1 and 2. Either of the jaws, l8 or l9, may be locked stationary in a predetermined position transversely of the supporting frame by screwing up tight its wing nut' 39.

Thereupon when the crank handle 3| is turned the other jaw will be moved toward or away from the stationary jaw according to the direction of rotation of the crank handle.

In the operation of the device the patient may be placed upon the seat and the seat adjusted by manipulation of the adjusting mechanism to comfortably dispose the patient with one leg resting in one of the padded depressions 22 of the jaws. To apply corrective compression the foot of the patient is thrust into the foot receivin concave walls 23 of the jaws l8 and I9 and thereupon the shafts 25 are manipulated to compress the foot at the ankle.

By slight and gentle pressure of the jaws on the deformed or dislocated bones of the foot or ankle, increased little by little, and simultaneous manipulation and massaging with the fingers ,of the operators hand, the tissues, ligaments and tendons are stimulated, and those adhered to the bones are loosened thus enabling the operator to more easily place each bonein its normal position. The treatments may be continued for from twenty to thirty minutes each, for days, weeks and months depending upon the age of the patient and the former care of the foot, until the deformed part is restored to normal condition. In some cases special pads are placed in the jaws to apply pressure at predetermined localized points to obtain the compression or pressure desired at these points during treatment.

From the above description it is thought that the construction and operation of the invention will be fully understood Withut further explanation.

What is claimed is:

1. Orthopedic apparatus comprising a frame, a seat adjustably mounted on the frame, compression jaws, means for adjustably mounting thel compression jaws to move transversely of the frame, pivoted compression pads carried by the jaws, and means for closing the compression pads upon the patients foot.

2. Orthopedic apparatus comprising a frame, a seat adjustable longitudinally of the frame, compression jaws adjustable transversely of the frame, said jaws being hollow, both jaws having limb receiving depressions in the top faces there- WALTER D, LANG FORD.
