Abstract
156,271. Duffus, R. March 21, 1918. Moulding-machines.- A moulding- machine, adapted to give a deep draw, having shafts 2 supporting the pattern plate moved vertically by cranks 9, connecting-rods 10, and clamps 11, is provided with balance weights 15 attached to the clamps by cords 16 or chains. The shafts 5 are guided in standards 5, which may be laterally adjustable and are fixed to a base 6 or over a pit. The levers 9 are secured on a shaft 8 operated by power or by a hand-lever 12, which can be lodged by a pawl 14. The pattern plate is carried by brackets 4 pivoted to heads 3 on the shafts 2 but locked thereto, when required, by a trip catch 19 and a hand-operated catch 20 on one of the heads 3 which engage projections 21 on the bracket 4. The base 6 has rails (not shown) for removing the moulding-boxes &c.
