Abstract: 161,169. Paley Engineering Co., (Assignees of Paley, L. A.). April 1, 1920, [Convention date]. Casting machines; endlesschain machines; moulding soap; cooling; delivery; feeding; moulds.-Soap, wax, gelatine, cocoa-butter, &c. is formed into cakes by running the hot fluid material into moulds which are conveyed through a cooling- chamber where the material is solidified by cooling below 25 C., the cakes are then stamped and are then preferably passed through a drier and conveyed to wrapping-apparatus. Figs. 3 and 4 show a machine comprising an endless chain of moulds 46 to which the soap &c. is delivered from one of a pair of crutchers 40 through valved pipes 43, the material being levelled by a scraper 48. The filled moulds are carried through a cooling-chamber 53 through through cold brine &c. is circulated by pipes 58, 59 and then pass under a stamp 98 carried by a lever 103 which is raised by a cam 110 and is depressed by a weight 118. After stamping, the cakes are discharged on to a shoot 120 and pass to a conveyer 122 which carries them to a wrapping-machine. Each mould section comprises a vertical wall 61, Fig. 6, from which projects at one side a base portion 62, and at the other, side walls 60, the base of one section cooperating with the side walls of an adjacent section. The sections are linked together by pins passing through interfitting portions 63, 64, and are driven by wheels 71 carrying pins 69 engaging recesses 68. A shaft 83, Figs. 3 and 4, driven through gearing from a motor 95 &c. imparts intermittent motion to the wheels 71 by an arm 84 engaging the projecting ends of the pins 69 and carries a locking-disc 81 adapted to engage recesses 80 in the flange 79. The cam 110 is mounted on a shaft 111 driven from the shaft 83 through chain gearing 111<a>. Cakes adhering to the moulds are detached therefrom by a spring- supported member 135 carried by an arm 133 mounted on a shaft 132 driven from the shaft 83 through chain gear. A pair of mould chains are arranged side by side in the machine. Figs. 11 and 13 show a modified machine in which the moulded cakes are conveyed through a drying- chamber before passing to the wrapping-machine. The cakes pass down the shoot 120a on to a distributor 142 upon which a number are accumulated, and are then delivered on to a conveyer 152, traversing a drying-chamber through which air is forced and which is heated by steam pipes 223. The distributor is provided with four cake-supporting arms 143 and is formed at one end with a squared shaft 144 slidably engaging a rotary member 155 furnished with locking-recesses 159 adapted to be engaged by dogs 156 to hold the distributor against turning during the accumulation of a row of cakes. The dogs 156 are tripped by collars 161, 162 engaging projecting fingers 160. The opposite end 145 of the distributor is connected to a mangle rack device 185 by which the distributor is reciprocated. A bar 164 cooperates with the distributor to deliver the cakes on to the conveyer 152 in the position shown in Fig. 11, and is carried by a shaft 165 which is rocked by pins 171 projecting from the member 155 and engaging an arm 169. Fig. 24 shows a further modification in which the stamping of the cakes is effected by a heavy roller 240 loosely supported in slotted bearings and notched at 242 to engage the mould sections. In this modification the mould sections are formed by a vertical wall 226, Fig. 27, carrying flexible side walls 238 which are pressed inwardly by side channels to close the mould cavities during filling and stamping, and when released they spring apart to free the moulded cake. The side walls are formed with inturned portions 239 to detach the cakes from adjacent mould sections. Interfitting lugs 228, 229 connect the mould sections together.
