766,962. Bottling. CROWN CORK & SEAL CO., Inc. Feb. 11, 1955 [Feb. 12, 1954], No. 4188/55. Class 125(2). The capacity of a rotating table filling machine is increased by providing at least two concentric rows 32, 31 of bottle rests above which are disposed two concentric rows of filling heads, the bottles being fed to the rests from two feed rows 80, 52. As shown in Fig. 1, the inner row of rests 32 is supplied with bottles from the feed row 80 by a pocketed endless conveyer 84 which overhangs the outer row of rests 31. The latter is supplied by bottles from feed row 52 by a star wheel 56. The rows 31, 32 have discharge stars 60, 160, closuring machines 64, 164, discharge stars 66, 168 and discharge conveyers 68, 170 respectively. The rests are raised by fluid-pressure and depressed by cam rails. They may have bottle-retaining fittings which can be telescopically retracted at the feed and discharge stations so as not to foul the feed and discharge means for the inner row of rests. In a modified form, Figs. 7-12 (not shown), cans are fed from an unscrambling device by two conveyers aligned radially with the filling table and each pair of rests (one inner and one outer) consists of a single platform having a lower outer ledge and a higher inner ledge on which the cans are held by magnets so as to overhang the ledges. At the discharge station, lugs on the upper run of an endless conveyer disposed tangentially of the filler engage the bottoms of the cans of the outer row ; and lugs on one run of a second conveyer engage the inner sides of the cans of the inner row. These lugs carry the cans tangentially away from the filler along guides to seaming apparatus. The filling heads for each pair of rests are coupled together and are of the rotating disc valve counterpressure type actuated by trips around the machine, means being provided so that the trips operate only if two containers are present. The coupling between the heads can be disconnected. Specification 522,229 is referred to.
