Abstract

637,197. Buckles. MEFFORD, F. E. July 11, 1947, No. 18426. Convention date, Jan. 1, 1944. [Class 43] A buckle, particularly for use in tourniquets, comprises a single length of wire having one or more curved or angular U bends in it, the ends of the wire being formed into oblong loops which lie one over the other in alignment with the U or U's. A single length of wire has two intermediate U bends 1, 1A, the ends of the wire being bent into oblong loops 2, 3, which lie one over the other, the loop 2 being narrower than the loop 3 so that gaps are left between the sides A, C and B, D of the loops. In another form the bend 1A is dispensed with. In use the ends E, F of the web 4 are passed up through both loops and then the end E is returned through the gap between the sides A, C, the end F being returned through the gap between the sides B, D. The ends may be pulled simultaneously or separately to tighten the tourniquet, release of either end being effected by lifting the appropriate U bend 1A or 1 In a modification, Fig. 7, the side B of the narrow loop 2 lies over the side D of the loop 3 leaving only one gap between the sides of the loops, i.e. between the sides A, C ; one end of the web is looped round the side C and secured, e.g. by stitching, the other end being passed up through the loop 3 only and returned through both loops. Alternatively, in a buckle similar to this modification but having a single, angular U bend, one end of the web is passed up through both loops, returned through the U bend, and secured, e.g. by stitching the other end being passed up through both loops and returned through the loop 3. The web is released by tilting the buckle upwards.
