FRACTURE-BOX.

To all whom it may concern Be it known that 1, Nuts Swanson, a citizen of the United States, residing at Muscatine. in the county of liiluscatinc and State of Iowa. have invented certain new and useful Improvements in Fracture-Boxes of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in fracture boxes, the object of the invention being; to provide an appa ratus of the above character which is especially adapted for use in the treatment of fractures in the lower portion of the le Another object of the invention is the provision of a device of the above character wherein the leg supporting member is adjustable to permit of the leg being raised or lowered, as desired.

A further object of the invention is to provide a fracture box of the above character whereby the same may be readily adjusted longitudinally to adapt the same to legs of various lengths.

A still further object of the invention is the provision of a fracture box of the above character which will possess advantages in points of efliciency and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

WVith the above and other objects in view, the invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in which Figure 1 is a side elevation illustrating the manner of use; F ig. 2 is a top plan view; Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2; Fig. 41 is an end elevation, parts thereof being removed; Fig. 5 is a front end elevation; and Fig. 6 is a top plan View, the leg supporting member being removed.

Referring more particularly to the drawings, 1 indicates the base member which is preferably hollow in cross section and slidably mounted upon the bottom thereof is an adjustable member 2 and arranged within the base and secured to the central partition 3 thereof is a rigid member 4:, to the outer end of which is hingedly connected the supporting member 5, the upper end of said supporting member being hingedly connected to a second supporting member 6 which Specification of Letters Patent.

is arranged beneath the box 7 and disposed between the two guide members 8. Mounted upon the supporting member 5 and adapted to more therewith is a bridge plate 9, the purpose of which will be hereiimfler more fully set forth.

liingedly connected to the outer end of the adjustable member 2 is the thigh box 10, the upper end of which is adapted to normally rest upon the bridge plate 9 and may be moved to various adjusted positions and retained in such position by means of the pivoted arms 11 which are pivotally connected, as shown at 12, and having the end portions thereof connected to the base and the box 1.0. Mounted upon the bridge plate 9 are the side boards 13, which are adapted to be arranged between the extended ends of the thigh box 10. These side plates 13 are connected to and are movable with the bridge plate 9. The ex tended ends 14 of the fracture box 7 are curved downwardly and provided with the elongated slots 15 in which the headed pins 16 are movable, said pins being carried by the side plates 13 so as to retain a connection between the fracture box and the side plates.

The bridge plate 9 and the fracture box 7 are pivotally connected by means of the links 17, one end of which is pivotally connected to the bridge plate and the other end pivotally connected to the supporting member (3. ivlounted upon the base 1 are the spaced bearings 18 in which are mounted the ends of the shaft 19 and mounted upon one end of the shaft is a wheel 20 whereby said shaft Rio end with an outwardly projecting arm 21, the outer end of which is hingedly connected, as shown at 20 to the supporting member 6 so that upon the rotation of the shaft 19, the fracture box 7 will be raised or low cred as desired.

Mounted upon the end of the shaft opposite the Wheel 20 a collar 23, which is provided with a plurality of openings 24; adapted to receive the downwardly projecting h e 25 which is formed upon the outer end of the pivoted pawl 26 so that when the fracture box has been raised or lowered to the desired position, the lug 25 will engage within one of the openings :24 and retain the shaft 19 against rotation.

At one end of the fracture box 7, an ad justable end plate 27 is provided which is hingedly connected to the bottom of the fracture box 7 and is adapted to provide a suitable foot rest to prevent further outward movement of the leg when arranged within the fracture box. The end plate 27 is re tained in various adjusted positions by means of the side bars 28, one end of each of said side bars being pivotally connected to the upper end of the plate 27 at each side thereof, while the other end of each of the side bars is provided with a plurality of teeth 29 adapted for engagement with a pin 30 upon each side of the fracture box to retain the end plate in various adjusted p0 sitions. The serrated ends of the bars 28 are arranged behind the guide rod 31 so as to prevent any lateral movement of the bars 7 during the operation.

Secured to the outer face of the plate 27 is an angular bracket 32 at the lower end of which is mounted a pulley 33 over which a cord 34 is adapted to pass, one end of said cord extending up and around the foot and is to be suitably padded, as shown at 35, so that the same will not cause any friction with the foot, the other end of said cord extending downwardly over the pulley and havin suitable weights 36 secured thereto so that the padded portion 35 will be securely retained in position around the foot so as to securely hold the foot in its proper position. From this it will be seen that after the leg has been placed in position, the padded portion 35 of the cord 34 is adapted to be arranged over the instep of the foot and the weight 36 placed thereon so as to securely hold the foot in position.

In Fig. 1, I have illustrated in dotted lines, a leg in its operative position within the fracture box, the lower portion of the leg being arranged within the box 7 while the upper portion thereof is e Tanged within the box 10. It will be readily apparent that in placing the leg within the fracture box, the knee should be arranged directly between the two boxes 7 and 10, so that when the shaft 19 is rotated to raise the box 7, there will be no opposition in the bending of the knee.

It will be readily apparent that my device, as illustrated and described, is extremely simple in construction, effective in operation, and can be manufactured and placed upon the market at a very small cost.

It will be apparent that during the adjustmentof the fracture box 7, the upper end of the box 10 which is engaged with the bridge plate 9 will be raised or lowered according to the adjustment of the fracture box.

lVhile I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features of construction or departing from the scope of the appended claims.
