Abstract: An improved outer reciprocating floor slat for use in a truck trailer or the like. The outer floor slat is located adjacent to a trailer's side wall. The floor slat has a portion that extends laterally upwardly and outwardly until it reaches the trailer's side wall at an elevation above the normal load-carrying floor elevation of the reciprocating floor slats. The upwardly extending portion facilitates material movement away from the corner region where the reciprocating floor normally intersects the trailer's side walls.

Abstract: A compact roll-off trailer is short and light, but able to carry a large load. As such, the unit competes with roll-off trucks. A horizontally tilt frame has a forward section coupled to a king-pin assembly, a rear section with wheels on at least two axles, and a mid section. A frameless version uses a set of opposing arms as opposed to a separate, non-tilting frame. A single hydraulic cylinder has a retracted state wherein the lift frame is generally horizontal for hauling, and an extended state wherein the lift frame is pivoted at an angle for loading and unloading. A mechanism may be provided for extending the rearward portion of the lift frame to ground level when the hoist frame is pivoted, and a mechanism for pulling a cable with a container attached thereto onto the lift frame for hauling. The mechanism for extending the rearward portion of the lift frame may either include a ‘stinger tail’ or a slide frame on the lift frame a hydraulic cylinder for extending and retracting the slide frame.

Abstract: The unloader system has a conveyor and a raise system having an elongate support element including a flexible first end portion and an opposite second end, the first end portion being connected to a support structure at a location higher than a first end of the conveyor, and the second end being connected to the conveyor at a location therealong adjacent to a free end thereof. A cam element is disposed on the support structure in a path of movement of the flexible first end portion of the support element such that as the conveyor is pivoted from the stored position toward the operating position the flexible first end portion will conformingly engage or bend about the cam element to raise the free end of the conveyor. The conveyor can include an elbow which is straightened by this action for raising the free end.

Abstract: A coupler for receiving first and second pins of an accessory. A first latching mechanism is associated with a first jaw, having an arm connected to and extending away from a latching member thereof, and a second latching mechanism is associated with a second jaw, the first and second latching mechanisms adapted to latch the first and second pins of an accessory in or on the first jaw and the second jaw, respectively. The second latching mechanism is powered for movement between a latching position and a non-latching position. The first latching mechanism is connected to, or connectable with, the second latching mechanism to allow operation of the second latching mechanism selectively to operate the first latching mechanism between its own latching and non-latching positions by means of a groove or flange or finger provided on the second latching mechanism.

Abstract: A loader mast-to-mounting frame pin arrangement is provided. The pin arrangement has stops added to a shaft that allow the pin to be held in two positions: the locked position and the parked position. In the locked position, a unique slot cut in the mast plate retains the pin by not allowing an eccentric protrusion on the shaft from passing through the slot when the pin is rotated to place the shaft in the top of the slot. When the pin is rotated so the shaft is towards the bottom of the slot, the eccentric protrusion is allowed to pass through the mast plate and the pin can be pulled out until it hits another protrusion on the shaft. At this point, the pin will stay in the mast but the loader can be removed from the tractor. To prevent the pin from rotating by itself, when in the locked position, and the loader coming unlatched, a spring loaded knob engages in the slot which prevents the shaft from being able to rotate to the unlocked position.

Abstract: A hay spear accessory apparatus for providing a secure and fixed mounting point for attachments such as ropes, chains, cables and the like, the apparatus being generally comprised of a an open-ended sleeve member having an interior diameter sized for slidable engagement over the distal end of a hay spear, the sleeve having attachment mounting means fixedly connected to the outer surface thereof. The interior of the sleeve has a varied diameter so as to accommodate the receipt of hay spears of various diameters. The apparatus of the subject invention is designed for frictional engagement with a hay spear, but optional securing means are also provided which prevent axial displacement of the apparatus along the hay spear once mounted thereon.

Abstract: As part of a system for processing workpieces, a workpiece support arrangement, separate from a process chamber arrangement supports at least two workpieces at least generally in a stacked relationship to form a workpiece column. A transfer arrangement transports at least two of the workpieces between the workpiece column and the process chamber arrangement by simultaneously moving the two workpieces at least generally along first and second transfer paths, respectively, that are defined between the workpiece column and the first and second process stations. The transfer arrangement can simultaneously move untreated and treated workpieces. Vertical motion swing arms and coaxial swing arms are described. A pair of spaced apart swing arms, the workpiece column and the processing stations can cooperatively define a pentagonal shape. Timing belt backlash elimination, a dual degree of freedom slot valve and low point chamber pumping, for removing chamber contaminants, are also described.

Abstract: A coupler for a backhoe or other excavator includes a frame including an upper portion and a lower portion. The upper portion is adapted to be secured to an associated backhoe or excavator arm. The lower portion includes a first hook adapted to mate releasably with a first associated attachment pin and includes a second hook adapted to mate releasably with a second associated attachment pin. First and second safety locks are movably connected to the frame and move relative to the first hook between an engaged position for capturing the first associated attachment pin in the first hook and a disengaged position for releasing the first associated attachment pin from the first hook. An actuator is adapted to move the safety locks selectively between the engaged and disengaged positions.

Abstract: A robot manipulator includes a plurality of joint shafts including at least first and second joint shafts. If the robot manipulator extends vertically with respect to a rotation center of the first joint shaft that rotates in a horizontal plane, a rotation center of the second joint shaft that rotates in another horizontal plane is offset from the rotation center of the first joint shaft.

Abstract: An improved Z-bar linkage for wheel loader machines for maneuvering an implement such as a bucket or pallet forks may include lift arms pivotally connected between an end frame of the machine and the implement, a tilt link pivotally connected between the implement and a tilt lever that is pivotally connected between the tilt link and the lift arms. Lift cylinders may rotate the lift arms to raise and lower the implement, and a tilt cylinder may drive the tilt lever and tilt link to rotate the implement between a dump position and a racked position. Ratios of the lengths of these kinematic elements are provided such that the good performance with one implement, such as bucket, does not result in poor performance with another implement, such as the pallet forks.

Abstract: A support rack has spaced vertical rails and horizontal upper, lower and intermediate rails. The horizontal rails are coupled to the vertical rails. A pivotable locking bar is between the horizontal rails. Side plates with rearward ends are attached to the vertical rails adjacent to the lower rail.

A rectangular ramp/platform has a forward edge extending forwardly of the vertical rails and a rearward edge extending rearwardly of the vertical rails and having parallel side edges. Hinges pivotally couple the ramp/platform adjacent to its forward edge to the side plates adjacent to their forward edges for movement between raised and lowered orientations. A cross support bar has ends attached to the ramp/platform adjacent to the side edges parallel with and rearwardly of the horizontal lower rail. The cross support bar is spaced above the ramp/platform.
