Abstract

20,646. Davies, R. Sept. 25. Couplings, non-automatic. - A shackle with a pin undetachable by jolting, for colliery or other trams or corves, is shown in Fig. 1. The eyes in the shackle are oval, the axis of the top eye being along the shackle and that of the lower transverse. On the pin are made two oval collars, the top one being flattened on one side at A to pass a dovetailed ledge E let in to prevent the lower collar B from coming out. The pin being inserted as shown, uncoupling is effected by giving the pin a half turn, lifting it through the lower eye and the hitching-plate, giving it another half turn, and then lifting it up until the lower collar B meets the ledge E. The lower edges of the collars, which are elliptical, are bevelled, and the edge of the dovetailed ledge is filed flat where it crosses the upper eye.
