Patented Feb. 21, 1933 UNITED STATES HARRY HERSCHEL LEITER, OF WARSAW, INDIANA STJ'RGIGAL EXTENSION ATTACHMENT Application filed September 29, 1930. Serial No. 485,233.

This invention relates to improvements in surgical extension attachments, and the object thereof is to provide a mount for a pulley that may be detaohably secured to a bed 6 frame of ordinary structure for the accommodation of a weighted cable which is usually used in surgery for applying constant tension to a fractured member of a patient during convalescence.

An illustrative embodiment of the invention is shown in the accompanying drawing, in which Fig. 1 is a perspective view of the attachment positioned for use upona bed frame, a portion of which is included in the view; and

Fig. 2 is a plan view of the appliance.

The attachment shown in the drawing is comprised of a spring frame, preferably formed of a single length of rod constituted of divergent arms 1 and a downwardly bent middle portion 2 contiguous with the corresponding ends of the arms. A pulley 3 is connected to the middle portion 2 by means of a swivel 4. and has extending therethrough a cable 5.

The outer end of each arm 1 is bent downwardly to form a primary hook 6 that extends substantially in a vertical plane, and the contiguous end portion of said arm is bent rearwardly so as to form a secondary hook 7 that extends substantially in a horizontal plane.

The rod of which the frame is formed is preferably of metal such as will admit of the arms 1 being sprung toward or from each other adjustably as may be required to fit the attachment to bed frames having differently spaced filling rods.

In applying the attachment to a bed, the frame is held in inverted position and the middle portion 2 upon which the pulley is secured is inserted between two of the filling rods 8 and beneath the top rail 9 on the foot of the bed frame, and is then moved up and backwardly over the top rail so that the primary hooks 6 enga e the top rail, and the secondary hooks engage and bear against the corresponding filling rods 8. When the attachment is thus applied the pulley is suspended from the end of the frame at a point spaced rearwardly from the foot of the bed in a vertical plane between the filling rods. The cable 5 is then strung through the pulley and applied in V the usual manner in connection with weights and the injured member of the patient (not shown) as in the ordinary surgical practice.

The frame preferably includes a covering 10 for the outer end portion of each arm, which may consist of a length of rubber hose slipped over the corresponding end of the rod so as to encase the secondary and primary hooks'and the adjacent portion of the corresponding arml. The coverings serve as cushions and prevent the frame from marring the finish on the bed frame.

The simplicity of the structure admits of, economic manufacture thereof, and the readiness with which the attachment may be applied without the usual fasteners is advantageous.

I claim: I

An attachment of the class described consisting of a spring frame formed ofa single length of rod having a bent middle portion and divergent members, the outer ends of which members are shaped respectively to provide contiguous primary and secondary hooks disposed in planes substantially at right angles to each other, said members being adapted to'be adjustably sprung toward and from each other whereby when applied to a bed the frame is clasped into connection with the top rail and filling rods thereof, and a pulley having supported connection with the bent middle portion of said frame adapted to receive a cable.

In testimony whereof I ailix my signature.

HARRY HERSCHEL LEITER.
