Abstract: A system for instrument conveyance may include at least one handling unit configured to dispense or accept instruments; at least one head unit configured to obtain input from a user in connection with a transaction involving instruments, where the at least one head unit includes a presentation opening between an interior side and an exterior side of the at least one head unit; a transportation system disposed between the at least one handling unit and the at least one head unit; and a shuttle device configured to transport instruments between the at least one handling unit and the at least one head unit via the transportation system, where the shuttle device includes an internal compartment for containing instruments, and where the shuttle device is configured to expose the internal compartment to the exterior side of the at least one head unit via the presentation opening.

Abstract: A bellcrank lever is pivotally connected at its elbow to a tow vehicle such as a tractor. A generally horizontal arm of the bellcrank lever is pivotally connected to the lower front portion of a trailer bed through a universal joint and a centering mechanism. The after end of the bed is supported by two rear wheels. A hydraulically actuated mechanism connected between the vehicle and an upwardly extending arm of the bellcrank lever pivots the bellcrank lever in a vertical plane thereby selectively raising or lowering the front of the bed. The universal joint allows towing and dumping at a considerable angle of lateral tilt of the bed relative to the vehicle and the centering mechanism maintains the trailer in fore and aft alignment.
