Abstract
627,226. Moulding hollow blocks by tamping- machines. NODARI, A. July 2, 1946, No. 19829. Convention date, June 8. [Class 87 (ii)] [Also in Group X] A tamping-machine comprises a mould 19 having a base plate 2 to which cores 5 are removably secured, a movable plate 45 which may be raised by fluid operated spindles 7 to eject a moulded block, a hopper 38 which is slidable over the mould to deposit. material therein, and a series of spaced thwackers 22 which may be raised pneumatically or mechanically and then allowed to fall under gravity to consolidate the material in the mould. The thwackers may be attached to guide rods 23 each of which is provided with an arm 26 one end of which engages with lifting teeth 27 on a chain 28 and the other end of which engages with a spring-urged catch 29 which, when in the operative position, maintains the thwacker in the raised position. A lever 30 is provided to operate the catches 29. The thwackers at the end of the series may be of C-section. Part of the mould may be masked off. A removable pallet may be placed on the plate 45.
