Abstract: Deep fat fryer having plurality of food-supporting baskets, individual motor and switch controls for raising and lowering baskets mounted in forward lower portion of fryer casing to facilitate servicing thereof.

Abstract: Safety interlock for operating handle of drain valve of deep fat fryer which blocks valve-opening movement of operating handle and is movable to unblocking position and thereby shuts off fry pot burner, subsequent valve-opening movement of handle maintaining interlock in unblocking position and interlock automatically returning to handle-blocking position upon movement of handle to valve-closing position.

Abstract: Deep fat fryer system of cabinet with plurality of separate fryers having oil supply conduits and drain means including selectively operable drain valves and extra large snap-out manifold, and a portable filter unit having motor driven pump mounted thereon with quick-connector to supply conduits, auxiliary support rollers on filter unit, and tracks in cabinet for receiving filter unit rollers to insure accurate alignment and connection of quick-connector; filter unit being employable with other fryers and for melting fat and transferring hot oil to any selected point of use.

Abstract: Dough sheet perforator comprising plurality of axially spaced and aligned star wheels rotating against individual resilient backup members as sheeted dough is passed therebetween to assure complete dough perforation resulting from extended scraping action of teeth of star wheels along associated backup members.

Abstract: A manually fed dough sheeter safely operable by anyone because of novel guard mechanism which physically prevents operator contact with sheeting rollers in operation, comprising dough piece receiving bin with top inlet aperture spaced well above rollers and defining passage thereto, first guard with lower portion blocking passage and movable by dough piece to move an upper portion to close inlet aperture, manually operable pusher for forcibly presenting to rollers dough piece stuck in passage, tray for receiving sheeted dough and enabling manual movement thereof through ninety degrees and sliding into second stage of sheeter, with second guard closely spaced above tray to prevent hand contact with second stage rollers, surface of tray being textured to substantially eliminate frictional resistance to dough sheet movement, and a circuit for controlling operation of roller driving motor manually or automatically for predetermined time in response to dough piece movement of first guard.
