TOURNIQUET Filed J l 12, 1943 Mrmn Wfiroikeng INVENTOR A'ITU R N EYE Patented Oct. 23, 1945 UNITED STATES PATENT ()FFICE TOURNIQUET Norman W. Brothers, Providence, R. 1. Application July 12, 1943, Serial No. 494,358

My invention relates to first aid appliances, 1

2 Claims.

.and has among its objects and advantages the handle.

Figure 3 is a perspective view of the limb encircling part of the tourniquet, and

Figure 4 is a sectional view taken along the line 1-4 of Figure 3. d

In the embodiment of the invention selected for illustration, I make use of a leather strap In of such length as to have overlapping relationship at its ends, as at I2 in Figure 1. The strap ends are tapered to feather edges l4 so that the limb engaging face 18 of the strap ID will fit uniformly tightabout the limb. A draw cord l8 circumferentially embraces the outer face of the strap Ill and is held thereon by guides 28.

Each guide 28 comprises a bar 22 spaced from the strap ID by spacing sleeves 24 mounted on rivets 26 which fixedly secure the bar to the strap.

The ends of the cord l8 are connected with a twisting handle 28. This handle is provided with atleast two slots 30 extending inwardly from its vertical edges 32. One end of the cord I8 is knotted at 34 and the cord length adjacent the knot is pressed into one of the slots 38. The other end is wrapped two or three times about the other end of the handle 28 and in the two slots 30 at that end. After such connection of the cord is, the handle 28 is turned to place a twist 36 in the cord l8, to draw the strap I 0 tightly about the limb 38.

The cord [8 is easily connected with the handle 28, and the handle provides a means whereby the cord may be effectively twisted to constrict the strap 10 upon the limb. The strap provides an effective constricting element and lies between the limb and the cord l8 so as to protect the limb from damage which would occur in case the cord alone were directly applied to the limb. The strap i0 is preferably formed of relatively thick leather and of such stiffness as to eliminate free bending. Thus the strap ends will slide freely relatively to one another as the cord I8 is progressively twisted.

Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.

I claim:

1. A tourniquet comprising a flexible strap adapted to be bent about a limb and having tapered overlapping ends, a plurality of guides attached to the exterior face of the strap, each of said guides having a bar disposed transversely of the strap, a rivetconnecting each end portion of the bar with the strap, a spacing sleeve on each rivet interposed between the bar and the strap, and a cord extending circumferentially of said strap and through the respective guides thereon.

2. A tourniquet as claimed in claim 1 comprising a handle for twisting the cord to constrict the strap upon a limb, said handle having spaced notches adapted to receive a knotted end of the cord in one of said notches and to have the other end of the cord wrapped about other notches therein.
