Abstract

171,041. Watts, H. W. Nov. 17, 1920. Rivet-extractors.-Chain-rivet extractors have the chain-engaging jaws pivoted to a cross-head or the equivalent and connected with the nut of the screw-punch in such a manner that the latter is centred with respect to the rivet, and the reaction of the nut locks the jaws tighter on the chain while the rivet is being forced out. As shown in Fig. 1, the jaws 2 are pivoted to a cross-head 3 slidable on the stem 6 of the screwpunch 7, and are connected to the nut 5 by togglelinks 4, the reaction of the nut acting through the links to increase the grip of the gripping- blocks 11 on the chain-roller 15 during the extraction of the rivet. A coil-spring 10 round the stem holds the jaws 2 normally in closed position. In the modification shown in Fig. 4, the nut 5 is connected to the pivoted jaws 2 by means of pins 18 on extensions 16 of the nut engaging converging slots 17 in the jaws. In the further modification shown in Fig. 7, the jaws 2 are pivoted at an intermediate point between handle members 14, curved recesses 21 in the jaws being engaged by the circular-shaped nut 5, the flat sides of which are formed with ribs 22 working in grooves in the handle members 14.
