ABSTRACT:
A push frame assembly for a scraper bowl is provided with a tubular structural member extending between, and being rigidly fastened directly to, the side walls of the push frame. A push block and a spreader tube are, likewise, connected between the side walls to produce a relatively rigid frame assembly. In one form of the invention, the tubular structural member has a transverse sleeve therethrough through which an ejector cylinder passes, while in another form of the invention, the tubular structural member has provision for receiving a differential and has reinforced mounts on the one side thereof for connection of ejector cylinders thereto. A method of making a push frame assembly is provided wherein a pair of side walls are fastened directly to a tubular member with a spreader tube and a push block framework connected to the side walls to produce a stronger push frame assembly.
