Abstract: 923,769. Endless conveyers; roller conveyers. DAVERIO A.G. Oct. 19, 1961 [Oct. 25, 1960], No. 37606/61. Class 78 (1). Semi - cylindrical stereotype plates 6 are conveyed on saddle members 25 carried by universally-jointed links of an endless chain 17. The members 25 have flexible curved extensions 31 (Fig. 3) which carry portions 41 for engaging the opposed edges of the plates 6. At a feed station 1 (Fig. 2) of the conveyer, the plates 6 are delivered by a roller conveyer 8 on to a roller conveyer 7 (shown enlarged at 42, Fig. 4). The underside of the middle of each plate 6 is engaged in turn by a pad 84 carried by a stirrup 83. This holds the plate 6 until a predetermined time synchronized with the running of the chain 17. The latter is driven by a chain wheel on a drive shaft 44 which also carries cams 56 and 57. The cam 56 operates a follower connected by a link 82 to the stirrup 83. When the latter is thus lowered the plate 6 is permitted to proceed on the conveyer 7 until its edges are engaged by stops 80 held in position until a predetermined instant by the action of the cam 57. The stops 80 are lowered when the next saddle member 25 of the chain 17 is a little in advance of the plate. The conveyer 7 runs faster than the chain 17 and brings the plate into position on the saddle member 25. Rails 37 engage projecting pads 35 carried respectively by the lower ends of the extensions 31 of the member 25, in the vicinity of the station 1 so as to guide the portions 41 into engagement with the respective edges of the plate 6. The plates are delivered to a conveyer 7 of a delivery station 1 which is of identical construction to the feed station 1 except that only one of these stations has a drive motor 50 for the chain 17. Pairs of rollers 64, 65, 66 of the conveyer 7 run free. A single pair of rollers 63 are driven by chains 52, 59 from the shaft 44. Pairs of rollers 67 to 72 are driven from the rollers 63 by chains 79 which pass over tension and guide pinions 80.
