Abstract

441,790. Moulding-presses. FAWCETT, Ltd., T. C., FAWCETT, D. L., and BOTTOMLEY, A. E., Whitehouse Works, Hunslet, Leeds. Oct. 2, 1934, No. 28111. [Class 87 (ii)] A press for forming bricks, slabs, tiles, &c. has vertically-guided connected pressure members k<1>, k<2>, the upper member carrying a plunger or plungers m for co-operating with the top of a fixed mould e, while the lower member k<2> carries a toggle link n connected to a link o pivoted to a plunger p adapted to move upwardly in the mould. In use, the pressure members which are counterbalanced, are raised by a cam-worked lever while a cam-worked slide g moves a charge of material from a hopper into the mould and, at the same time, ejects the formed article. The pressure members are then lowered to a position determined by a stop u. The toggle levers are then closed by a cam s, thus applying pressure to each end of the mould. In some cases, the pressure members are raised to polish the article before the toggle is opened. The toggles may be operated by a cam-worked connecting-rod.
