Abstract
This invention relates to a buckle usable for securing the two ends of a looped band together about a workpiece, the new and unusual feature being directed to the provision of a distortable element provided in the buckle body which as a tension applying tool draws up on the complementary band the distortable element of the buckle gives a visual indication of the appropriate or predetermined tension having been applied to the band. Thereafter, the buckle and band are permanently set relative to each other.
Claims4
In a buckle for securing ends of a complementary looped band together about a workpiece under predetermined tension, said buckle including a body having substantially parallel spaced top and bottom walls and side walls joining the top and bottom wall to each other, means on said bottom wall of said body to accept and anchor a first free end of the complementary band, said top and bottom walls of said body providing a throat to accept the second free end of the complementary band, said top wall presenting an edge against which a complementary tensioning tool can be seated for stretching the complementary band to a predetermined degree of tension, said top wall having a slot intermediate its margins traversing a substantial portion of its extent and extending between said side walls, a top wall portion at least one side of said slot being distortable as force is applied against the edge by the complementary tensioning tool to visually indicate that the desired tension has been applied, and means for securing the second end of said band relative to said buckle to permanently set the said band relative to said buckle in tensioned condition.
