Conveyor shift assembly and product cart with conveyor shift assembly
First Claim
1. A shift assembly and mounting bracket assembly for mounting a conveyor to a mobile cart, the cart having tires for moving the cart in a fore and aft direction, the shift assembly comprising:
- an attachment bracket to mount the shift assembly to a support and forming a ground link;
a parallel linkage movable having first and second parallel links each coupled at a first end to the attachment bracket; and
a coupler connected to the other end of each of the first and second links whereby the coupler maintains a fixed attitude relative to the attachment bracket as the first and second links are moved; and
a mounting bracket assembly connected to the coupler and adapted to mount a conveyor thereto;
wherein the parallel linkage is limited to movement in a generally vertical plane in the fore and aft direction whereby the mounting bracket assembly is movable between a lowered position and a raised position.

Abstract
A product cart has a frame and one or more tanks forming compartments each having an opening at the upper end for receiving product. The cart includes a conveyor support having a swing arm with a first end pivotally mounted to the frame for motion generally horizontally between storage and use positions, a shift assembly mounted to a second end of the swing arm, and a mounting bracket assembly coupled to the shift assembly. Finally a conveyor is coupled to the mounting bracket assembly. The swing arm is constructed as a parallel linkage having first and second links which form a four-bar parallel linkage with the frame and with the shift assembly to maintain the shift assembly in a fixed orientation relative to the frame as the swing arm is moved. The shift assembly is operable to move the mounting bracket assembly between lowered and raised positions.
