Filter jacket for cooking oil

Claim 1

In combination with a food cooking apparatus employing cooking oil in which particles of food, food coatings and the like become deposited and which is disposed in a container and capable of circulation in a flow path having an intake in the container, a cleaner assembly immersed in the cooking oil in the container and interposed in the flow path of the cooking oil, said cleaner assembly including a screen member disposed in the flow path of the cooking oil, said screen member including a top and bottom member of mesh material having the peripheral edges engaged with each other and the central portions spaced apart to form a hollow interior with the intake of the flow path for the cooking oil being disposed in the hollow interior for causing cooking oil to flow from the exterior to The interior of the screen member when entering the flow path, paper filter elements disposed in the flow path and completely covering and engaging the exterior surface of the screen member for removing material from the cooking oil as it passes into the hollow interior of the screen member and being subject to clogging thereby thus requiring frequent replacement of the paper filter elements inasmuch as the paper filter elements are incapable of withstanding abrasive action of scraping material from the exterior surface thereof, that improvement comprising a cloth member disposed against and completely covering the exterior surface of each paper filter element to collect particles from the cooking oil as it enters the hollow interior of the screen member, said cloth being characterized by an exterior surface capable of frequent and repeated scraping of particles and other material therefrom without removal from the container and flow path and without disturbing the screen member and paper filter elements thereby materially extending the time that the paper filter elements can be used before replacement, said top and bottom mesh members and paper filter elements being generally in the form of circular discs, a pair of annular rings engaged with the peripheral edge of the discs, means clamping the rings together thereby clamping the discs together for retaining the top and bottom mesh members and top and bottom paper filter elements in assembled relation, said cloth including a top and bottom generally disc-like member having a diameter greater than the top and bottom mesh members and the top and bottom paper filter elements and the rings with the periphery of the cloth disc-like members extending beyond the periphery of the rings to provide a peripheral area on each of the cloth disc-like members beyond the periphery of the rings to enable the cloth disc-like members to be grasped and stretched taut as the clamping means for the rings are actuated thereby retaining the cloth disc-like members substantially wrinkle-free to facilitate scraping of particles and other material from the exterior surfaces thereof.
