Abstract: 156,599. Union Wrapping Machine Co., (Assignees of Streich, F.). July 23,1917, [Convention date]. Rotary-mould-table machines; delivery; feeding; coating apparatus.-A dough-divider comprises an horizontal intermittently-rotated table furnished with measuring-chambers equipped. with plungers adapted to actuate trip mechanism controlling the table-rotating mechanism. As shown, a table 50, Fig. 2, secured to a shaft 49 driven from a main shaft 34 through gears 65, 64, carries measuring-chambers 51 fitted with plungers 52 furnished with rollers 54 running on a track formed by a fixed cam 59, Fig. 6, a trip member 60 and bridge-pieces 61, 62 hinged respectively to the member 60 and cam 59. The member 60 is carried bv a lever 73, Fig. 9, one end of which is depressed by a spring 79 and carries a roller 76 normally engaging a cam 77 on a clutch member 66 carried by the shaft 34 to hold the clutch member out of engagement with a driving member 38 against the action of a spring 67, as shown in Fig. 2. The table 50 rotates below a plate 16 which supports a casing 23 carrying feed rolls and a hopper 24, the casing being hinged at 19, Fig. 1, and secured at the opposite side by a clamp. Within the casing is mounted a pair of feed rolls 26, Fig. 2, which force the dough through a throat 26a and opening 16a in the plate 16 into the chambers 51. The rolls 26 are coupled by gears 27 and are driven from the clutch member 38 through a chain 35, shaft 30, clutch 32, and fast or slow trains 29, 28 or 31, 27. Motion is imparted to the member 38 through reducing-gear 43, 44 from a motor 39, Fig. 1, or other means. The dough fed into the chamber 51 depresses the plunger 52 until the roller 54 engages the member 60 and trips the lever 73, whereupon the clutch member 66 is forced into engagement with the member 38 by the spring 67 causing the table to rotate and cut off the measured quantity of dough. As the roller 54 leaves the member 60, the spring 79, Fig. 9, again forces down the roller 76 which engages the cam 77 on the clutch member 66 and disengages the latter after one revolution. As the rollers 54 travel over the cam 59, Fig. 2, the plungers are raised to eject the dough portions which are removed by a scraper 100 and pass down a shoot on to a conveyer passing around a roller 103, Fig. 1. The scraper 100 is carried by an arm 99 secured to a shaft 97 which is rocked by a cam 105 on the shaft 34. Flour is deposited on the table 50 from a receptacle 109, Figs. 1 and 2, fitted with an agitator 114 which is oscillated through a lever 118 and link 119 by a cam 122 on the end of a shaft 123 driven from the shaft 30 through a chain 125. The bottom of the receptacle 109 is formed with apertures regulated by an apertured plate 111 adjustable by a screw. To vary the capacity of the measuring-chambers, the member 60, Fig. 9, is adjustable by a screw 85 operable through bevel gear 87 by a shaft 88 which may be actuated through a handwheel 93, Fig. 1, and chain 91. The capacity of the chambers is indicated by a scale 96 and pointer 95, the latter being secured to a shaft 94, Fig. 6. forming the hinge of the member 62. To prevent the machine being driven when the casing 23 is raised about its hinge for cleaning, &c., the lever 73, Figs. 2 and 9, is provided with a lug adapted to be engaged by a locking-member 129 carried by a rod 127 which is normally depressed by the arm against the action of a spring.
