432,799. Moulding bricks &c. by rotary mould - - table machines. HEAD, G., 14, Beaufort West, Grosvenor, Bath. Jan. 27, 1934, No. 2875. [Class 87 (ii)] Bricks, blocks, tiles and the like are moulded by charging a mould box or boxes k carried on a horizontal continuously rotatable mould table f, compressing the material in a horizontal direction and discharging, all in one continuous operation. The mould boxes k are carried beneath a fixed plate d provided with filling apertures e, e<1> for different materials, the inner side s of each mould box being movable to compress the material in the box. The material may also be compressed in a vertical direction by moving the bottom m of each mould. The table f is secured by angle irons g to a gear wheel p driven from a main shaft r, the irons g co-operating with the parts of the outer walls h of the mould boxes which extend below the table f to form guides for rams l which carry the mould bottoms m, the rams l being provided with rollers n engaging a circular cam track o. The inner sides s of the mould boxes are reciprocated by the engagement of rollers t thereon with a stationary cam u. After compression, the article is lifted out of the mould box by the ram l and is ejected by a pusher 19 on to a pivoted platform 20, the platform being then turned over by hand to deposit the article on a conveyor 22. The pusher 19 is attached to a rack 16 actuated through a gear wheel 15 from a member 10 pivoted to the plate d, the member 10 being rotated in a direction to advance the pusher by the engagement of an inner edge of the ram l and the bottom m with a roller 11<1> on the member when the ram is in its fully raised position, and being rotated in the reverse direction by the engagement of the inner edge of the ram and bottom with a roller 13 on a toothed disc 12 engaging the member 10.
