Abstract
A mobile brick molding machine includes a rectangular frame with a mold therein, the mold being a grid with open top and bottom ends for receiving a brick-forming composition when resting on the ground. The frame is provided with a wheel at its front center and a pair of wheels at the rear end thereof. The front wheel supports a jack, which is connected by a cable to a lever supporting one of the rear wheels whereby raising of the front end of the frame and mold using the jack results in virtually simultaneous upward movement of the rear end of the frame leaving the molded bricks.
Claims2
A mobile brick molding machine comprising a frame having an open bottom end;
- mold means mounted in said frame for vertical movement therewith;
- hopper means movably mounted on said frame means for filling said mold means with brick forming composition;
- first wheel means for directly supporting one end of said frame for vertical movement with respect thereto, said first wheel means including
- jack means for raising and lowering said one end of said frame, and
- a ground engaging supporting wheel connected to said jack means;
- second wheel means for directly supporting the other end of said frame for vertical movement with respect thereto, said second wheel means including
- lever means for raising and lowering said other end of the frame,
- ground engaging supporting wheels rotatably mounted on said lever means, and
- linkage means interconnecting said jack means and said lever means for operating said lever means such that raising said one end of said frame by said jack means results in simultaneous movement of said lever means and its wheels and raising of said other end of said frame by said lever means thereby moving said frame and said mold means from a first lower molding position to a second upper mold releasing position.
