Abstract: The load supporting and moving surface of the conveyor is made up of longitudinal members called slats. The slats are edge to edge with small gaps between the edges. The slats are supported on bearing parts and bearing strips which are supported on longitudinal beams which are evenly spaced and extending lengthwise of the cargo space of the conveyance in which the conveyor is installed. The longitudinal beams are supported by and fastened to the cross beams of the conveyance. The longitudinal beams, bearing strips, bearing parts and slats of the conveyor are all installable from directly above the cross beams. The slats are held in place vertically by interlocking with the bearing parts. There is a juncture formed at every contact between a longitudinal beam and a cross beam. Bearing parts are installed a 10% to 50% of the junctures. The conveyor also comprises means to reciprocate the slats a stroke length. The longitudinal length of each bearing part is between 0.5 and 0.95 of the stroke length.

Abstract: The propeller drive is installed with its drive shaft inside a boat hull and it's driven (propeller) shaft outside. The shafts are interconnected by a silent chain. The drive shaft position is adjustable to adjust the distance between it and the driven shaft, thus adjusting tension in the chain. The drive shaft is carried in two bearings which are installed eccentrically in two bearing carriers. The bearing carriers are rotatably mounted in a casing and are structurally interconnected by a connector. The adjustments are made by rotational adjustment of the connector relative to the casing.

Abstract: The load supporting and moving surface of the conveyor is made up of longitudinal members called slats. The slats are edge to edge with small gaps between the edges. The slats are supported on longitudinal bearing strips, one edge of each slat on one strip, the other on an adjacent strip. The bearing strips are supported on longitudinal beams, evenly spaced and running lengthwise of the cargo space of the conveyance in which the conveyor is mounted. The longitudinal beams are supported by and fastened individually to crossbeams of the conveyance. The bearing strips slide longitudinally onto the longitudinal beams and the slats slide longitudinally onto the bearing strips. Clearance is provided for fastening the longitudinal beams from above. The upper surfaces of the bearing strips have longitudinal grooves in the center of their upper surfaces. Flanged ribs on their lower surfaces engage the flanges of the longitudinal beams to hold the strips in place. The edges of the slats are over the grooves.

Abstract: The conveyor forms the floor of the trailer and is made up of longitudinal slats slidably supported on cross beams. In a center frame trailer all the cross beams are supported on longitudinal beams. In a frameless trailer some of the cross beams are supported on longitudinal beams which are part of the suspension apparatus for the trailer. In both types of trailers three of the cross beams are activated to activate the slats. These three activated cross beams are called cross drives and are slidably mounted and positively guided directly on the longitudinal beams.

Abstract: The subject invention is for use in reciprocating conveyors in which the load is carried and moved by groups of side-by-side slats which reciprocate longitudinally. The slats in each group are attached to a drive member and the drive members are actuated by the subject system to move the groups of slats in unison in one direction and sequentially in the other. The system includes a linear, double acting hydraulic actuator for each group and connected to the drive member for that group. The actuators have equal strokes, different piston areas and are connected in parallel to the hydraulic power supply. The actuators and drive members are arranged such that for motion in one direction the actuator having the largest piston area and its drive member cannot move until the other actuator(s) and drive(s) can move and thus they move in unison in that direction.

Abstract: A reciprocating floor conveyor has at least one group of at least three individually reciprocatable slat members. A drive engages each slat member and moves more than half of the slat members simultaneously in a conveying direction and moves the remainder of the slat members in the opposite direction at least at about twice the rate of speed. The drive includes a fluid pressure source, a flow divider connected to the fluid pressure source which provides a separate, equal rate of flow for each slat member, a separate extensible fluid driven cylinder for reciprocation of each slat member that is connected to a separate flow from the flow divider, and a direction valve for each fluid driven cylinder which controls fluid flow into and out of the cylinder.

The exterior edges of two of the slats fit the top groove of the central guide bearing, and the sides of the pair of slats are located adjacent the legs of the central bearing. A side bearing is located in each of the base section bearing seats.

Abstract: The reciprocating floor conveyor of the present invention includes a supporting frame, a plurality of base members on the supporting frame, a plurality of elongate, slidable slats mounted on the base members, and a drive mechanism for causing longitudinal reciprocative movement of the plurality of slats. The plurality of slats are divided in at least a first and second interleaved groups. Each slat is connected to the slats adjacent thereto through slidable engagement of the sides of the slats, and are supported by the base members such that the first group of slats is elevated a greater distance from the supporting frame than the second group of slats. The drive system of the present invention is employed wherein the reciprocating floor conveyor is comprised of at least three slat groups each having at least one slat member each. The drive system moves all of the slat groups simultaneously in an extended, conveying direction and moves each of the slat groups sequentially in an opposite, retracted direction.

Abstract: A slat-type conveyer for unidirectional movement of a load is disclosed. A first drive interconnected with a bed causes bidirectional longitudinal movement of a first load bearing slat group in a first direction and a second direction. A second drive interconnected with the elongate bed causes longitudinal movement of a second load bearing slat group simultaneously with the movement of the first slat group in the first direction, and sequentially with respect to the movement of the first slat group in the second direction. A unidirectional load transporting surface on both the first slat group and the second slat group causes movement of the load when the first slat group and the second slat group move simultaneously in the first direction, but does not cause substantial movement of the load when the first slat group and the second slat group move sequentially in the second direction.

Abstract: An elevating transport vehicle has its frame carried by steerable idler bogies and by drive wheels on an axle assembly having a mechanical drive via a telescopic drive shaft from an engine and transmission mounted on the frame. The drive axle assembly is supported beneath the frame by a pivotally mounted tie rod and swing arm at each side of the vehicle. Hydraulic cylinders act between the frame and the bogies and swing arms to raise and lower the vehicle frame and with a telescopic drive shaft from the first to the second drive axle assembly.
