Carrier and drive means for two-axes type refrigerating conveyor

Claim 1

Apparatus for driving two-axes type refrigerating equipment comprising a frame, a pair of spaced drums rotatably mounted on said frame on substantially vertical axes, each of said drums having a plurality of peripheral ring means spaced along the vertical axis thereof, the ring means of one drum being staggered relative to the ring means of the other drum, each of said ring means having a generally vertical portion and a generally horizontal portion, friction means mounted on said vertical portion of each of said ring means, anti-friction means mounted on said generally horizontal portion of each of said ring means, conveyor means semicircumferentially disposed about each of said ring means and being inclined between drums, said conveyor means being supported by the generally horizontal portion of each of said ring means, one edge of said conveyor means engaging the friction means of each of said ring means to provide the sole driving force for said conveyor means, means for rotating said drums at substantially the same speed, and means for tensioning said conveyor means, whereby said tensioning means causes said one edge of said conveyor means to intimately engage said friction means on said ring means so that rotation of said drums will drive said conveyor means.
