Abstract: A discharge control apparatus for the rear slide gate on the tail gate of a truck box comprises a rod mounted horizontally across the tailgate from a free beyond one side of the tail gate. The rod is formed in two portions which can divided as a coupler between a center section of the tail gate and a side section of the tailgate. The rod portion of the center section is connected by a pair of cranks to the slide gate. A lever on the free end of the rod can be rotated manually and the rod locked at a required position to hold the slide gate at the required opening. The coupling can be disconnected by pulling the side rod portion away from the center rod portion to allow the center section to be opened.

Abstract: A combination lifting hinge and latching mechanism for a tailgate used on a refuse hauler and compactor. A hydraulically operated lifting hinge is comprised of three principle components, namely, a hydraulic cylinder, a bell crank and a cam plate secured to the tailgate. A pair of lifting assemblies is disposed at an upper location each side of the cylindrical compactor body such that it is not easily damaged, and further, allows the compactor body to extend laterally and vertically to the maximum highway guidelines. The lifting mechanism first lifts the tailgate from the locking position such that locking pins clear side spur latches before rotation. Due to the unique camming feature and a kidney-shaped slot in the cam plate, an over-center locking feature is provided. The tailgate cannot be inadvertently lifted from a locked position due to upward forces, such as the truck hitting a bump, even if the actuating cylinder should relax its holding forces, such as during a hydraulic failure.

Abstract: A tailgate assembly is disclosed for use with a dump truck which has a bed, two side walls and a bed opening, and also has an obstruction, such as a tag wheel assembly, spaced relatively closely to the bed opening. The assembly comprises a tailgate pivotally connected to hydraulically operated arms for moving the tailgate between open and closed positions. Guides restrict the tailgate to a first substantially rectilinear path of travel and lost-motion connections prevent relative pivoting of the tailgate with respect to the arms to cause outward swinging of the tailgate with respect to the truck bed during a second path of movement to prevent interference between the tailgate and the obstruction during sequential opening of the bed and the raising of the bed to its dumping position.

Abstract: A collector cart includes a body having an open rear end closed by a canopy pivotally connected to the body adjacent their front ends. A tow bar, which has the body pivotally connected thereto, has a support, which has caster wheels connected thereto for support, for the body. The tow bar has a quick hook-up requiring no tools at its forward end for connection to a hitch on a riding lawn mower. When the cart is to be dumped, a first handle is rotated by an operator, who remains on the mower, to initially cause pivoting of a rear portion of a frame of the canopy, which includes a cover on the frame, relative to the body and the remainder of the canopy frame to unlock the rear portion of the canopy from the rear of the body. After unlocking is accomplished, a second handle, which is pivotally mounted on the body and has a portion engaging the tow bar to prevent pivoting of the body, is rotated by the operator to disengage its engaging portion from the tow bar.

Abstract: A dump truck body has a bed and side walls defining a rear opening which is closed by a tailgate and loader unit removably attached to adaptor brackets inserted into the side walls. The unit includes a U-shaped frame supporting extendable tracks which carry a vertical tailgate supported for pivotal movement to form a horizontal platform. The frame also encloses two pairs of oppositely directed hydraulic cylinders which move the tracks, and a cam mechanism is shifted into alignment to pivot the tailgate between horizontal and vertical positions in response to movement of the tracks. The entire unit is pivotally supported by the adaptor brackets to pivot from the truck body when the body is inclined for dumping or when a pair of hydraulic cylinders are actuated.

Abstract: A dump truck is provided with a dump body having a tailgate. A lever arm having a first end and a second end is pivotably attached to the dump body. The first end is fixedly attached to the tailgate and the second end is attached to a latching device which locks the position of the lever arm. When the dump body is raised, the latching device is deactivated and the position of the lever arm is unlocked. When the dump body is lowered, the latching device is activated and locks the position of the lever arm, thereby locking the position of the tailgate.

Abstract: A collector cart includes a body having an open rear end, which is closed by a canopy pivotally mounted adjacent its front end on the body adjacent its front end. The body has a support pivotally connected to caster wheel supports and a tow bar attached to a riding lawn mower hitch plate. Telescoping chutes connect the mower outlet with a canopy port to fill the cart with debris. When the cart is to be dumped, a first handle is rotated by an operator, who remains on the mower, to initially cause pivoting of a rear portion of a frame of the canopy, which includes a cover on the frame, relative to the body and the remainder of the canopy frame to release a locking connection of the rear portion of the canopy frame to the rear of the body.

Abstract: Gate operator and latch mechanism in which a refuse container is provided with a gate which is pivotally attached to the refuse container and which normally closes an opening through which refuse is discharged from the refuse container. A latch mechanism secures the gate in closed position. The operator mechansim is operably joined to the gate for pivotal movement thereof. The operation mechanism is also operably joined to the latch mechanism for operation thereof.

Abstract: A refuse compacting system having an elongated hopper of rectangular cross-section with an ejection opening at one end, a tailgate movable for opening and closing the ejection opening, a refuse entry opening in the top of the hopper, a compactor within the hopper, located at one end, and pairs of dual parallel connected cylinders for moving the compactor towards the ejection opening and back again.

Abstract: My dump-truck Tail Gate Spread Chain Release has oppositely spaced bearing members mounted to the dump-truck tail gate adjacent the bottom edge thereof. A chain release holding and release toggle member is pivotably mounted between said spaced bearing members. I fasten a cantilevered arm to said pivotable member, extending upwardly therefrom and fastened fixedly but removably to said truck tail gate. The chain is held in a slotted opening in said pivotable member at selective spaced intervals so that the tail gate may be adjusted to any desired position for allowing materials therein to fall from the truck body. When it is desired to release the chain from the weight of the tail gate and materials in the truck, the cantilevered arm is released from the upper portion of the end gate and the pivotable chain holding member is then pivoted downwardly from dead center in the direction of the pull of said chain, allowing said chain to be easily removed from said slotted opening.

Abstract: A rear door control mechanism for a stack-forming implement having a compressor roof first raises the door vertically to unlatch it and then rotates the door about an elevated and horizontally transverse axis to permit stack unloading. The door control mechanism functions independently of the compression roof and other wagons' mechanical systems and assures positive door unlatching before the opening mechanism attempts to open the door.
