Abstract

15,740. Rigby, J. S. July 8. Moulds.-A portable apparatus for moulding concrete props, posts, &c., comprises a frame e mounted upon three wheels j traversing a moulding-floor x and a number of partitions or knives a secured to crossbars b, o, and suspended from the frame by levers c, g mounted on shafts d,f. The knives a taper longitudinally and also from top to bottom to facilitate their withdrawal from the moulded articles, and are operated for withdrawal by a lever i carried by the shaft f. A plate m, fitting into recesses n in one end of the knives a, closes one end of the moulds, the other end being formed by a plate or board p secured to the cross-bar o by bolts q. In operation, the knives are lowered on to the floor x, the plate m inserted and the moulds filled with concrete. The plate m is them removed and the knives a &c. withdrawn longitudinally and upwards by operating the lever i. The knives &c. are then held by a pin w engaging a lever h connected to the shaft d, and the frame e is moved to another position. Holes may be formed through the posts by cores inserted through holes u in the knives a.
