489,203. Endless - chain conveyers. FERREE, J. W. July 20, 1937, No. 20050. [Class 78 (i)] [Also in Group XXII] In a casting- machine comprising spaced endless chains 4 carrying moulds 5 and supported and driven by wheels 18, 6, the moulds are removably connected to brackets 49, Fig. 3a, of the links 31. Each roller 18 has an outer flange 20, Fig. 6, to retain the chain links 31, and a ball bearing 25 lubricated by passages 27 in a fixed axle 22. The links 31, Figs. 5 and 9, each have horizontal flanges 33, 34 connected by a web 35, and a tongue 37, with a hole 37<1> and a slot 43, at one end and two spaced tongues 38, with holes 38<1> and a stop 44, at the other. A sleeve of wear-resistant metal such as manganese steel having a projection to engage the slot 43 is inserted in the hole 37<1> of each link and these are connected, after assembling, by hollow pivots 32, each having a collar with a flat engaged by the stop 44 to prevent relative rotation. The two chains are connected by rods 47, passing through the pivots 32, secured by cotters 48, and by single or double pig moulds 5, Fig. 3a, and the brackets 49. The wheels 6 have double teeth 59, Figs. 1 and 3a, spaced to engage the portions of the pins 32 projecting from each side of the links.
