Abstract

186,875. Smith, A. H. Sept. 16, 1921. Chains.-The links of sprocket chains are made by a pair of relatively movable dies, which sever a blank from a strip, pierce the necessary holes, and bevel one side of the link in one operation thereof. The fixed die consists of a blank punching die 43, a die 44 with faces 45 for bevelling one side of the blank, piercing tools 42, a marking tool or piercing tool 49 and a slidable ejector 48, which is perforated to surround and support the tools 42, 49. The tools are shouldered at 47 to abut against a cross bar. The movable die 40 is provided with holes 41 in alignment with the piercing tools 42. The dies are arranged with their axes horizontal so that the completed links, when ejected, fall clear of the dies. Specification 186,395 is referred to.
