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.

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.

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.

Self-leveling dispenser of the type having an elongated lever which serves to balance the spring and platform, with a member being adjustable along the lever for altering the ratio of effective moment arms to change the effective spring rating of the dispenser. An adjustment feature comprises felxible strands connected to opposite sides of the adjustable member. By means of a pulley surface, both strands leave the lever at the pivot point and proceed to a take-up pay-out device, shown as a dentent-controlled reel. For avoiding working against the spring during adjustment the lever concavely curves about the line of action of a tension spring acting upon the lever. In combination of these features the strands are guided by longitudinally convex surfaces of the curved member. The platform and spring loads are shown to act in one diagonal direction of a rectangular frame with the frame braced by a tension member extending in the opposite diagonal direction.

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.

A sliding file support to cooperate with a dual access file system having a central longitudinal upwardly open U-channel. At least one side of the channel has an outer surface and at the top of the side a lip with an inner surface. The element comprises a slider and a loop for an end stop. The slider carries two rear, lower legs with inner bearing surfaces; also a third, lower forward leg longitudinally between the other two and with an inward bearing surface. The slider also carries a ledge longitudinally between the rear legs, and a hook longitudinally spaced from the legs. In operation the hook is hooked under the lip of the wall, the ledge rides on the top of the wall, and the bearing surfaces clasp the wall between them in sliding engagement. The body and the support are readily engaged and disengaged.
