Abstract
204,414. Smith, W. H. July 1, 1922. Stationary-mould machines.-In a block-moulding machine of the type described in Specification 166,633, the mould bottom is operated by a double toggle mechanism, one toggle serving to compress the material and the other to eject the moulded block. The toggles are connected at different points to a common transmission lever which is fulcrummed about the end of one toggle while the other is in operation. The press comprises a mould A which may be provided with a core s and has a movable bottom B supported by pressure rods C carried on a cross-head D sliding in hollow standards E protected by grit-proof covers. The compression toggles K operated by a lever F through a. link J are connected at one end to a fixed pivot K<1> and at the other end to the transmission lever H by a pivot k. The ejection toggles 0 are similarly operated by a lever G through a link N and connected to pivots P, h. The mould is filled from a hopper Z and is closed during compression by a plate Q normally supported above the mould by arms R and a spring S. The plate Q is held in position, and drawn downwards during the compression, bv a link U which is pivoted to the transmission lever H and adapted to engage a projection T on the rod R. The link U is freed from the projection T by means of a link V connected to a bell-crank lever W operated by a cam Y on the lever F.
