To all whom it may concern Be it known that we, RnINHoLn H. GRIP? and JOSEPH Pyononen, citizens of the United Statearesiding at Oakland,.in the county of Alameda and State'of California, have invented certain .new and useful Improvements in Soap-Casting Machines, of which the following is a specification.-

Figure 12 is a sectlon on l1ne 1212 of In the drawings lindicates the frame of the machine which includes an intermediate section 2 and end sections 3 and 4. A shaft 5 is journaled in bearings 6 on the frame section 3, which shaft carries two sprockets 77.- A. shaft 8 journaled in bearings 9 on the frame section-4 carries two sprockets 10 extend chains 11--11 respectively.' On the chains 11--,11 at suitable intervals are mounted soap molds 12. Each mold includes a rectangular box-shaped mold receptacle 13 in the form of a soap cake, a mold frame 14 and a mold lunger 15. The frame-14 is formed with a ower transverse member 16, and side members 17-17 between and to which side members the mold receptacle 12 is detachably secured by means of screws 18.

the ends thereof are formed bearings 19-49 from which trunnions 20-20 extend later ally through the bearings of upstanding 21 at at rear end of. the molds 1 2 are Pics.

The links 1 On each of said side frame members 17 at formed with elongatedrearwardly extending bearings 22 through which ,the rear trunmons 20 ofthe :mold extend, which bear-. ings allow sald trunnions to move rearwardly therein to. enable the chains 11 to carr the mold around-the sprockets 7 and 10. 25 extends from the plunger 15 in each mold through an aperture 26 in the bottom of the mold andthrough a bearing 27 in the lowerframe' member 16. A spring 28 surrounds rod each rod '25 between the lowerframe memf ber 16 and ahead 29 on the end of the rod, which. spring holds the plunger 15 against the bottom of the mold receptacle 13. The upper reach of the chains 11 travel through a refrigerating tunnel 30 .mounted in the upper part of the intermediate frame I section 2, in which tunnel is a refrigeration coil 31. .The lower reach of the chains 11 travel through a refrigeration tunnel 32 mounted in the lower part of. frame section 2, said tunnel being provided with a refrigeration coil 33. Inside the tunnel 30 are mounted'rails'34-upon which the chains 11 travel through said tunnel and are maintained horizontal against sagging under the weight of the soap in-the molds. A shaft 35 journaled in bearings 36 on the frame 3 carries a pulley 37 and sprockets 38 and 39. A sprocket 40 is secured on' the shaft 5 in alignment -with sprocket38 over which sprockets travels a chain 41 whereby the shaft 5 and the chains 1111 are driven.

Near one end of the machine above the frame sections 2 and 3 is mounted a con,-

tainer in lwhich is placed liquid soap.'

Said container has an outlet 51 in the bottom thereof whih leads into a soap pump 52' mounted on the bottomof the container, a

flange 53 being formed around .the' said outing box 64 in the pump casing. On the outer end of the valve stem'a collar 65 is pinned by a pin 66. A spring 67 surrounds the stem 62 between the packing box 64 and the collar 65, said spring normally holding valve 61 closed and preventing the liquid soap from flowing into the pump. The pump casing has a socket bearing 70 below the same end of the cylinder 57 into which the duct 59 leads, and with a duct 71 leading from said end of the cylinder into said socket bearing. On the upper end of a spout 75 is formed a hollow 'ournal 76 which fits in socket bearing 70. aid bearing is made in arts 77 and 78, the part 77 being formed on tile pump casing and. the part 77 being bolted to part 78 by bolts 79 which extend through a flange 80 on part 78 and screw into a flange 81 on the part 77. The part 78 has a slot 82 through which the spout 75 extends, said slot being long enough to alow the spout to oscillate forwardly and backwardly with relation to the chains 11. The journal 76 has an openin 83 in its upper wall which registers with uct 71 and admits liquid soap from the cylinder 57' into the journal and spout 75. A nozzle 80 screws onto the lower pivot with a longitudinal slot 113 through which extends and in which slides a pin 113 on the disk 108. The lower end of said lever is connected to one end of a link 114, the other end of which link is pivoted by a pin 115 to a clamp 116 on thespout 75.

On the frame section 2 before the entrance to the tunnel 32 is a cam 120. A chute 121 extends from a point belowthe cam 120.

The operation of our invention is as follows:

The chains 11 are driven in the direction of arrow (see Fig.1) through the medium of the capacity of a mold 12, is drawn from the container 50 into the cylinder 57 through inlet 55, port 60, and duct 59, while the spout end of spout 75, said nozzle being formed 75 is swung backwardlydirectly over a mold with an inlet duct 81'with which the spout 75 communicates, an outlet duct 82 and a port 83 leading from said inlet into said outlet. A valve 85 controlsport 83, the stem 86 of said valve extendin laterally from the nozzle through a bearing 7 formed in the wall of the nozzle. A collar 88-is pinned on the outer end of stem 86 by a pin 89. A spring 90 which surrounds said stem between the bearing 87 and collar 88 normaly closes the valve 85. A plug 91 is screwed in an opening 92 in the wall of the nozzle 80 opposite va ve 85, through which opening the valvemay be inserted or removed when the plug. is removed. A plu 93 is screwed in an opening 94 in the we l of the pump opposite thevalve 61, through which opening said valve may be inserted or removed when the plug is removed. To the outer end of the cylinder 57 is bolted a head 95 in which is a bearing 96 through which extends a piston rod 97 to which the piston 58 is connected. A frame 98 extends from the head 95 and has a bearing 99 in its outer end through which also the piston rod 97 extends. A collar 100 is secured on the piston rod 97 from which collar projects a pin 101. In a bearing 102 on the pump 52 is journaled a shaft 103 on one end of which is secured a disk 104. A pitman 105 is pivotally connected to disk 104 by a crank pin 106 and to the piston rod 97 by pin 101 and collar 100. Onithe shaft 103 are also secured a sprocket 107 and a disk 108. A chain 109 travels over sprockets 107 and 39. A lever 110 is pivoted by a pin 111 on an arm 112 depending from the bearing 102, said lever being provided at one side of its 12 which has arrived at the top of sprockets 7. As said mold travels forwardly the piston 58 is moved inwardly; the valve 61 is closed; and the charge of liquid soap is forced out of the cylinder 57 through duct- 71, opening 83', journal 76, spout 75 and nozzle 80, (the valve 85 opening to permit the soap to pass through inlet 81, port 83 and outlet 82), into said mold, filling the mold, (the spout swinging forwardly with the mold and remaining directly over it while dischargin the soap therein). When the moldsare lled with the liquid soap they are carried through the tunnel 30in which the soap is cooled and hardened in the mold. As each mold comes under the cam 120 the head 29 at the end of piston rod 25 engages said cam, which 'forces the piston 15 downward and the cake of-soap, which has hardened and formed, out of the mold onto the conveyor 121, which conveys the cakes of soap to a suitable place of discharge where it discharges them.- The molds 12 are further cooled as they pass through tunnel 32.

The molds after passing through the tunnel 32 are chilled so that when the soap is poured therein and passes through tunnel 30 and hardens it shrinks and is easily ejected from the mold without cracking.

The disk 104 is provided with a plurallty of holes 130, 131 and 132 in which the pm 106 may be placed, said holes being located at difierent distances from the cenpump and the size of the soap cake. The

pin 106 is formed with a journal 133 and a flange 134 on its outer end on which the pitman 105 is hung, said journal being of greater diameter than the rest of the pin and providing a shoulder 135 which engages the outer face of the disk. The inner end of the pin is threaded to receive a nut 136 which engages a washer 137 on the pin against the rear face of the disk and draws the shoulders 135 against the outer face of the disk.

1. A machine for casting soap including a conveyor, soap molds mounted on said conveyor, a soap pump, a swinging nozzle on said pump, automatic means for actuating said pump to pump liquid soap through said nozzle, means for swinging said nozzle so as to follow each mold on the moving conveyor until it delivers enough soap to fill the mold, and means for removing the molded soap cakes from the mold.
