Abstract: An elongated container of a truck has a closed front end wall and a hinged rear outlet closure, and a side infeed opening for receiving garbage. This empty container is configured to receive an elongated base upon which is mounted a reciprocating conveyor floor for moving garbage in the container outward through the opened rear closure for deposit at a garbage disposal site. The power drive mechanism for driving the reciprocating floor is located at the front end of the container and is shielded from input garbage by a deflector secured to the reciprocating floor. The deflector also serves as a pusher for compacting and moving garbage in the container out through the opened rear closure. The self-contained reciprocating floor is easily carried manually and fed through the opened rear closure and secured firmly in the truck container.

Abstract: The container of a mobile cargo trailer is provided with a reciprocating slat type conveyor floor in which the elongated slats are supported at their lateral edges on V-shaped bearings which are mounted on Y-shaped supports integral with sub-deck sections on the container bottom and joined together with watertight seals. Three cross beams are connected to different groups of the slats and are coupled to hydraulic cylinders located outwardly of the front end of the container and in horizontal alignment with the slats. The cylinders are coupled to a hydraulic fluid pressure source through an arrangement of control valves to effect movement of the group of slats simultaneously in a load moving direction and sequentially in the opposite, slat-retracting direction, with interengaging abutments on the cross drives arranged for moving one of the cross drives and its slats by hydraulic power applied only to the other two cross drive cylinders.

Abstract: A cargo transfer system provides a transport trailer floor with a plurality of guide tracks that slidably support a floor platform having substantially the same dimensions as the full size cargo floor of the trailer; a similar plurality of support guide tracks being provided in a shipping/receiving facility arranged for axial and elevational alignment with the guide tracks of a transport trailer positioned in the loading/unloading bay of the facility. A powered drive mechanism associated with the guide tracks in the facility releasably engages a floor platform member to push or pull the floor platform member along the aligned guide tracks between the transport trailer and the facility whereby to load or unload the entire contents of transport trailers in a single movement of the floor platform therebetween.

Abstract: A fluid pressure piston-cylinder drive unit is reciprocated automatically by coupling the opposite ends of the cylinder through delivery conduits to a source of fluid pressure and exhaust through a switching valve in which a longitudinally reciprocative spool has a pair of passageways which reversibly couple one end of the cylinder to the source of fluid pressure and the other end of the cylinder to an exhaust conduit. The opposite ends of the switching valve contain shift pistons each of which engages an end of the spool through a coil spring. The shift pistons abut the opposite ends of an elongated rod which extends freely through a bore in the spool. Bypass conduits couple the opposite ends of the cylinder through the delivery conduits one to each end of the valve body such that fluid pressure in one delivery conduit from the source is coupled to one end of the valve body while exhaust fluid pressure from the other delivery conduit is coupled to the other end of the valve body.

Abstract: A reciprocating conveyor includes a plurality of elongated, load-supporting reciprocative slats mounted on a plurality of elongated, slat-mounting base members secured side-by-side across the supporting frame. Each reciprocative slat mounts a pair of elongated bearing members for reciprocative movement therewith, the bearing members configured to engage the base members to secure the reciprocating slat for reciprocative movement relative thereto, and are further configured to provide a seal thereagainst to restrict the passage of particulate material to the base members to a minimum, and also are configured to engage any such material that should escape the seal and enter the space beneath the reciprocating slat to continuously push said material toward and out of one end of the reciprocating conveyor with each successive movement of the reciprocating slat in that direction during operation of the conveyor.

Abstract: A reciprocating conveyor includes a plurality of groups of reciprocating slats supported on a main frame, each group of slats being connected to a separate drive beam by releasable clamp bolts extending through laterally elongated openings in the drive beam for accommodating alignment of the slats with adjacent slats. The drive beams are connected detachably to the piston rods of hydraulic piston-cylinder drive units through quickly attachable and detachable clamps, and the drive units are formed as a drive module that is readily attached to and detached from the main support frame.

Abstract: A load positioning and conveying system includes a plurality of groups of elongate conveyors, wherein each group includes at least two conveyor slats.

Abstract: A reciprocating conveyor includes a plurality of elongated, load-supporting reciprocative slats mounted on a plurality of elongated, liquid-impervious slat-mounting base members secured side-by-side across a supporting frame. The adjacent sides of adjacent base members are interconnected by a waterproof seal, whereby the assembly of base members forms a waterproof floor under the reciprocative slats. A liquid collection receptacle is mounted on the frame adjacent one end of the base assembly to receive the liquid content of a load supported on the slats, and a drive mechanism for reciprocating the slats is contained within the receptacle and connected to the reciprocative slats through slots formed in the base members above the collection receptacle.

Abstract: A reciprocating conveyor comprised of a plurality of elongated, reciprocative, load-supporting slats mounted on a conveyor frame for reciprocative movement relative to the frame, is mounted detachably on an underlying support frame which carries integrally therewith a hydraulic drive mechanism arranged to releasably engage the load-supporting slats for reciprocating the latter on a predetermined sequence for moving a load in an off-loading or on-loading direction.

Abstract: A reciprocating slat type conveyor comprises a framework mounting a bed of longitudinally extending, laterally spaced apart first and second groups of alternating slats arranged for longitudinal sliding movement on the plane of the bed. Interposed between adjacent reciprocating slats is a fixed slat mounted immovably to the framework, each fixed slat having an upper material supporting surface that is narrower than the upper material supporting surface of each first and second reciprocative slat.

Abstract: A reciprocating conveyor is formed of at least one group of at least three elongated slats of inverted U-shape spaced apart laterally for longitudinal reciprocation in such manner that all or a majority of slats move simultaneously in a load conveying direction and sequentially in the opposite, retracting direction. A seal member is secured to one side section of each slat and extends laterally therefrom to a position closely adjacent the facing side section of the adjacent slat. The fines of particulate material being conveyed as a load gravitate downward past the free side of the seal member and are deposited in a trough that underlies each pair of facing side sections of adjacent slats. As the adjacent slats move simultaneously in the load conveying direction, the corresponding pair of facing side sections move the fines in the trough in the same direction. This movement is enhanced by providing fines pusher members on the lower ends of the side sections of the slats.

Abstract: A plurality of elongated slats are arranged side by side to form an elongated conveyor, and they are connected to three transverse drive beams in such manner as to form the slats into a plurality of groups of three slats each. Each drive beam is connected to a pair of fluid pressure drive cylinders disposed on opposite sides of the beam so that as one cylinder pushes the beam the other cylinder pulls it. Control valves communicates the cylinders selectively to a source of fluid pressure to reciprocate the slats in a manner to effect moving a load supported thereon in a predetermined direction. The plurality of slats thus form a reciprocating conveyor which moves a load in one direction at a predetermined speed.
