Abstract: 126,525. Baker & Sons, J., (Baker, R. E., Ford, E. H., and Cummins. A. F.). June 28, 1918. Endless-chain conveyers with platform carriers; discharging and feeding devices; guiding. -Continuously-running conveying mechanism specially adapted for use in proving dough has carriers and cranks pivoted thereon, consecutively-adjacent cranks being connected by links and adapted to engage stationary guides. The heated chamber 25, Fig. 1, contains a continuously-running conveyer which passes around sprockets 27, receiving the trays &c. 43, Fig. 12, at the opening 25<1>, travels, as indicated, by dot- and-dash lines to the opening 25<11>, where the trays are removed automatically, and returns beneath the floor 26 of the chamber to the charging-opening. The conveyer is shown as having four horizontal runs, two long and two short, and two vertical runs. The conveyer is formed of a number of tubular rods 39, Figs. 6 and 7, on each of which are firmly secured, by means of split sockets 42" and nuts 44, a number of carriers 42, each having raised ends 42<1> to form stops for the tins. The shafts are carried by brackets 34 from axles 30 which are provided with loose sleeves 29 carrying flanged wheels 31 running on rails 45, and connected together by pairs of inclined links 28, the end portions of which form eyes which engage the loose sleeves 29. The rollers 31 are hollow and each has a plugged oiling hole 32 and a felt or like washer 33, while an opening 29<1> in the sleeve allows oil to reach the axle 30. The axles are provided with cranks 35, connected by light links 37, the purpose of winch is to maintain the carriers 42 in their horizontal positions, not only when running along a horizontal portion of the track, but when passing upwards or downwards around a sprocket. This is accomplished by means of a roller 38 on the outer end of each crank, running in a guide channel 46, Figs. 2 and 4, along the sides of the chamber, and around guide disks 48, 49 fixed on the axle of each sprocket wheel. One of the idle sprockets 27<1> is adjustable to take up slack by means of a slide 27" operated by a screw 27a or other device. At 'both the charging and discharging openings there is fixed a comb-like platform 50<1>, Fig. 5, which allows the shafts and the carriers to pass in such a way that in the upward travel past the charging opening the carriers will receive and carry away the trays placed upon the platform, while in the downward travel past the discharge opening they will leave the trays on the platform, as indicated in Fig. 12. To steady the conveyer on its downward travel, two spaced guides 65, Figs. 4 and 5, are attached to the opposite walls of the chamber. The sprocket 27 is the only driven one, the others running idly, and its shaft 81 is driven from an electric or other motor driving the shaft 74 through spurreducing gearing, as shown in Fig. 12. To discharge automatically the trays from the combreceiving platform 50<1> to an outer platform 25b, a shaft 52, Fig. 12, supported on standards 51 is driven by a chain from the shaft 69. The shaft 52 is connected by mechanism, fully described in Specification 127,208, to racks 63 which are connected to a cross-bar or pusher.
