Abstract: 156,625. Peters Machinery Co., (Assignees of Peters, F. M., and Hungerford, W. H.). Aug. 5, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Stearn-cutting machines; reciprocating-mouldtable machines; feeding.-In a machine for subdividing plastic materials, e.g., butter, the material is forced by a pair of worms arranged within a casing 25, Fig. 1, through an outlet 46 into a cylinder 48 fitted with an internal sleeve 49, Fig. 5, which is turned to cut off the supply; a plunger 64 forces the material from the sleeve through conduits 93, 94 into a pair of measuring- chambers 112 fitted with plungers 111 which, after lowering of the chambers 112 to shear off excess material, are advanced to eject the measured portions; the ejected portions are severed by a wire 126, Fig. 1, and are received upon a pair of paper strips 139 supported upon a slat conveyer 149 and are conveyed from the machine, the paper being severed between successive blocks of material during the passage from the machine. A power shaft 39 drives through gears 38, 37, a main shaft 36 which drives the feed worms through gears 37, 35, shaft 34, worm gear 32 and gears 31. The plunger 64 is operated through rods 68, and a cross-bar 66 by pistons working in a pair of compressed-air cylinders 70 controlled by a rotary valve operated by a rod 77 which is moved in one direction by a spring and in the other direction by a cam 82 on the shaft 36 acting through a rod 80 and bell-crank lever 79. Rotation of the sleeve 49, Fig. 5, to cut off the feed, is effected by gearing engaging teeth 52 and driven by a rack-bar controlled by a cam on the shaft 36 Pressure on the plunger 64 is relieved at the end of its stroke by a whistle valve 201, Fig. 16 actuated by a cam 204 on the valve spindle 92 The measuring-chambers 112, Figs. 1 and 5, are carried by a slide 96, and are moved vertically by a lever 99 counterweighted at 103 and operated by a grooved cam on the shaft 36. Movement of the plungers 111 is limited in the outward direction by stops 114 contacting with adjustable stops on a fixed plate 115, and in the inward direction by pins 116 engaging stops 117. The plungers are moved inwardly to eject the material by a plate 120 operated from the shaft 36 through a crank and rod 123. After ejection, the protruding material is severed by a wire 126, Fig. 16, carriec by a frame 206 connected by a link 223 and leve: 222 to a rod 216 which is controlled by a spring 217 and a cam 212 on the shaft 36. The paper strips 139, Fig. 1, are supplied from rolls 135 loosely supported in brackets 133 and driver frictionally by a roller 136 mounted on a shaft 129 driven from the shaft 36 by a driver 130. The conveyer 139 passes around sprockets 146 mounted on a shaft 143 which is driven from the shaft 36 through ratchet mechanism 225, 141, 142. Severance of the paper between the blocks of material is effected by a guillotine knife 169, Fig. 11, carried by a frame 168 reciprocated by rack gearing 166, 167 actuated through bevel gears 163, 162 by a shaft 156 which is operated by a rack bar controlled by the shaft 36.
