ABSTRACT:
Apparatus for forming concrete building blocks which is constructed and arranged (1) to minimize sound emissions to the environment of a magnitude which might cause injury to the hearing of the operators, (2) to provide shielding around the major movable components of the machine so as to substantially eliminate potential causes of bodily injury to the operators, and (3) to improve the performance and cooperation of the major components for making concrete blocks. To provide shielding against noise and bodily injury, the frame of the apparatus is constructed in conjunction with sound insulation panels to provide an enclosure around the major movable components of the apparatus, and the frame also supports these components on internal surfaces thereof so as to minimize sound transmission openings to the environment. The various components, such as the feed drawer assembly, sizing and compression head assembly, strip mechanism, pallet eject and feed assembly, pallet magazine and the like, are improved and arranged to provide optimum performance not merely from sound and safety standpoint, but also to assure most favorable operation from the standpoint of cycle-time, trouble-free operation, ease of servicing and the like.
