Abstract: 1,105,660. Strap-tensioning tools. THOMAS & BETTS CO. 11 Aug., 1966 [11 Aug., 1965], No. 36039/66. Heading F2G. A tool for applying a strap 30 to articles, e.g. groups of wires 31, comprises a casing 20, in which a handle 22 is movable relative to a fixed handle 21, has a strap registration plate 26 in which is rotatably positioned a strap twister plate 28, and a shaft 24 reciprocable in the casing and connected to the handle 22 by a link 23. The handle 22 pivots on a pin 52 on a plate 32 held under the tension of a spring 53 and carrying a gear segment 56 which engages with a pinion 33. A cutter blade 37 is positioned in a recess in the plate 28. The free end of the strap 30 is positioned through opening 40 in the plate 26 and the under spring-loaded pawl 41, the handle 22 being then moved toward handle 21 to progressively move the strap into the tool. Release of the handle causes the shaft 24 under the action of the return spring 53 to return to position against the plate 26 during which movement the pawl lifts and slides over the strap. When the strap has been tightened, link 23 moves pin 55 in slot 65 in the shaft so that the normally retracted dog 59 is brought into engagement with a rack 61 to lock the shaft against axial movement whereafter the upper end of the handle 21 connected at 52 to the member 32 causes the gear segment 56 to rotate the pinion 33 which is fixed to and rotates a tube 34 thereby rotating the strap twister plate 28 and the shaft 24. The strap 30, while rotated, presses against and is sheared by the cutter blade 37. The point at which the shaft will rotate to cut the strap is predetermined by the degree of tensioning of a spring within the shaft section 24b and such adjustment is measured on a scale on the tool casing. The tension of the spring 53 connected to the member 32 is adjustable also.
