ABSTRACT:
Metering apparatus includes a casing defining spaced first and second chambers and respective first and second piston members sealingly slidable by applied fluid pressure in the chambers. Support member coupled to and moveable with the second piston members projects from the casing to receive a load to be metered. Located within the first piston member is a third chamber in which a plunger is sealingly slidable. The second and third chambers are in communication whereby respective opposed transverse faces of the second piston members and the plunger are engageable to determine a limit position for the second piston means in the second chamber. In a preferred application, the metering apparatus is incorporated in a block forming machine, for example a cheese block forming machine, in which the load support platform is positioned within an upright housing to receive a column of a solid medium confined within the housing. Such machine further includes horizontally acting guillotine member to sever blocks from the column, the size of the block being determined by the limit position for the second piston member in the second chamber.
