The foot pedal 38 is connected to a link 41 which may be secured to a rod 43 that extends upwardly into engagement with the cutter 36. Thus, by applying downward pressure on the food pedal 38 the cutter 36 can be caused to cut the wax paper 37 from the roll 34 to any desired length. I
Extending forwardly from the machine is a trailer hitch 44, and the hitch.44 may be attached to any suitable towing vehicle so that the machine can be moved to any desired location. A pair of vertically disposed spaced parallel guard members 45 extend upwardly from the beams 11 and are secured thereto, and the guard members 45 are arranged adjacent the front end of the machine. Each of the beams 11 has a plurality of rollers 46 journaled therein so as to rotatably support the molds 33 as they move along the frame. A tank 56 is arranged adjacent the motor 20 for holding fuel such as gasoline. Mounted on the rear end of the frame is a housing 47 which is adapted to contain a quantity of mortar or concrete therein which is to be dispensed into the moving pans or molds 33 so that when the mortar hardens bricks, building blocks and the like will be formed. There is further supported on the frame a container 48 for holding coloring matter whereby the mortar or building blocks can be colored or tinted asdesired. The color container 48 is provided with a plurality of radially extending partitions 49 which define compartments therein, Figure 6, whereby a plurality ofdiiferent colors can be arranged in each of the compartments. A shaft 50 may be secured to the rotating container 48 so that as the shaft 50 rotates the container 48will rotate therewith. For rotating the shaft 50, a gear wheel 51 is mounted thereon,
and a rod 52 has one end arranged contiguous to the gear,
Arranged within each of the compartments in the color containerAS is a mixer 57, and each of the mixers 57 includes a shaft 58 having a. gear 59 on its outer end. A vertically shiftable shaft 60 is arranged exteriorly of the container 48, and the shaft 60 has a yoke 61 on its upper end, there being a shaft rotatably supported by the yoke 61.1 A bevel gear 62 is mounted on an end of the shaft 65, and the bevel gear 62 is mounted for movement into and out of engagement with the gears 59 as the shaft 60 is raised. A roller 64 is journaled on the.
' were? lower end of the shaft 60, and the roller 64 is adapted to be engaged by the'moving pans or molds 33 to thereby raise the shaft 60 in the stationary bracket 63. After the mold 33 has passed, the parts will return to the position shown in Figure 3 by gravity sothat the mixers 57 will no't' 'be actuated until another mold comes into position. An endless chain 66 is trained over a sprocket on the 'drive shaft 21, and the chain 66 is also trained over a sprocket on the shaft 65 for rotating the shaft 65 to thereby rotate the mixers 57 when the shaft 60 is in'its raised position. A horizontally disposed screen 67 is arranged in the container 43 for insuring that no lumps f color matter are dispensed into the molds.
The mortar container 47 is shown in detail Figure l and arranged exteriorly of the housing or'contai'ner 47 is a vertically'disposed shaft 68 which has a gear 69 mounted thereon.'--'A "shaft70 is spaced from the shaft 68;andtheshaft 70'ext ends down" into the housing 47 for rotating lTliXel s 711" Awornrn is mounted on a shaft 73,"and the worm 72'n1eshes with the gear 69, the shaft 73 beingoperatively connected to the-drive shaft ZI'by a'chain and sprocket connection 74, Figure 2. The top end of the shaft 68 is connected tothe top end of the shaft 7tl"by a chain and sprocket mechanism 75. Braces 76 may be provided for helping to support the hOhSing 47 which remains stationary.
A means is provided for automatically dispensing color and mortarfrom the containers '48 and 47 into the moving holds 33 as the molds '33'are conveyed along by the conveyor 27. This means comprises trip members 77 and 78 which are engagdby the molds as the molds travel'along. The tripmember 77 actuates a valve to permit "color to be dispensed onto the mold from the container 48, and the tripmember 78 actuates a valve to permit mortar to be dispensed into the mold from the container 47. The trip member 77 is connected'to a rod or bracket which has a vertical portion 85, Figure 3, and extending from the vertical portion 85 is a horizontal portion 83 which terminates in a second verticalportion 82 which is connected toa shift ng plate 80. The shifting plate 88 is provided with an opening 81 which is adapted to register with one of a plurality of cut-outs r open n 79 i e t m Q th con ain 1 Th h h o nin s 7 and .81 t ain r i te the color f on of the-com ar m n w Pass er hr a onto the mold 2 2.therebelow The mold 33 actuates the trip and opens the valve in the bottom of the container 48 by engaging the trip member 77 to movethe plate 88 to the position shown in Eigurexl.

The color is distributed evenly from the rotating housing 48 and the screen 67 insures that no lumps will be dispensed. The mortar from the container 47 is also evenly distributed as the mold passes therebelow and after the mold passes ,from beneath the container 47 the mortar dispensing slot becomes closed.
The roll of wax paper 34 may be insulated so that adverse weather conditions will not cause the wax paper to stick and the automatic dispensing of color will-insure that no color will be wasted. Further, the work can be done in less time and with less effort than if the casting were done by hand, and the finished product will be of high quality. The parts can be made-in any de sired size or shape.
