US Patent:
39894320, Nov 2, 1976
Filed:
Feb 18, 1975
Appl. No.:
5/550466
Inventors:
Charles W. Depka - Carlsbad CA
Assignee:
Modern Builders Supply Co. - Oceanside CA
International Classification:
B28B 308
B28B 1305
US Classification:
425139
Abstract:
During stripping of a cement block from a mold in a cement block forming machine by shoes of a stripper head, the head is driven by gravity and its distance from a pallet receiver structure, including a pallet receiving the cement block, is limited by hydraulic, collapsible stops. The stops collapse during stripping a distance sufficient to slump the block. The amount of collapse during the stripping time interval is controlled by adjustable hydraulic flow means under constant pressure.
