An automatic sandwich preparation system including a meat patty and bun storage and delivery system. The patty system includes a number of canisters containing meat patties mounted on a carrousel and tilted inwardly toward the center of the canister. An ejection blade slides the bottom patty from the bottom of a selected canister onto a wire conveyor. Each canister is coded for the size of the meat patties contained in it. The carrousel is mounted in a freezing chamber. The bun system includes parallel shelves holding the bun portions in rows separated by step-driven dividers. The bun portions are delivered from the trays into a bun transport that in turn delivers the bun portions to a toaster.

Method and apparatus for handling buns and meat patties

An automatic sandwich preparation system in which each sandwich is prepared under the control of a computer with condiments as ordered. Shredded lettuce is delivered by an automatic volume measuring mechanism or by a weight responsive delivery system. Condiments such as mayonnaise and mustard are delivered by a volumetric pump and a flexible spreader blade that rotates over a screen above the surface of the bun. In an alternative arrangement, radial dispensing orifices rotate over the bun followed by a flexible spreader blade. In another alternative, the condiments are fed individually through flexible tubes to the bun surface while the positions of each of the delivery orifices are controlled by a common mechanism.

Apparatus for automatic application of condiments to a sandwich

An automatic sandwich preparation system in which each sandwich is prepared under the control of a computer with condiments as ordered. Meat patties are packaged in spaced positions along a plastic strip and then frozen. The strips are packed in shipping and storing containers that are received by the automatic sandwich preparation equipment. The meat patties are removed from the strip by directing the strip over a small diameter roller that frees the patty. Two face-to-face plastic strips may be heat sealed to form pockets for the meat patties and also for serving portions of other sandwich components such as chopped vegetables, catchup, mustard and the like. The contents are removed by physical separation of the two strips. In another arrangement, ground meat is formed into a log shape that is frozen. While the log remains frozen individual meat patties are sawed from the log.

Apparatus for processing sandwich ingredients

A three pole relay which operates in response to the flow of normal operating current across fluorescent lamps to activate a coil, the coil coperating a relay to open switches disposed in all of the filament lines associated with the lamp to shut off filament current while maintaining current flow across the lamps themselves.

A power returnable tape rule has an improved connection between the outer end of the power spring and the inner end of the coilable rule blade provided by interengaging element thereon. The rule blade has an elongated aperture adjacent its inner end with the margins of the blade defining the aperture including opposed inwardly extending finger portions. The tongue is configured with spaced transversely extending shoulders facing in opposite directions, and it extends along the upper surface of the rule, downwardly into the aperture under the fingers and upwardly from the aperture and forwardly thereof along the upper surface of the rule blade. The shoulders on the tongue of the spring abut the margins of the aperture adjacent the finger portions in either direction of relative longitudinal movement to limit such movement and retain the two elements in assembly.
