Abstract: An apparatus and method for an improved self-dumping cart. The dump cart has a box pivotally mounted on a frame and wheels. The cart box is normally locked to the frame in an upright position for loading and towing. Then to dump, the box is unlocked from the frame and locked to at least one of the wheels, so that upon rotating the wheels in a rearwardly direction, the cart is dumped. Preferably, the box pivots 180° between the loading and unloading positions.
Abstract: A handle-propelled, load-carrying land vehicle comprises a frame having two parts, one having wheels and ground-engaging pedestals forward of the wheels, and the other being pivoted to the front of the first part and having a load-carrying receptacle mounted on it and having a telescoping handle. The device is balanced so that it can be easily propelled by pushing downward and forward on the handle. It is especially useful as a dumping hand cart for granular loads, since the forward edge of the receptacle is spaced from the ground at least at the completion of the dumping operation. A gravity-operated latch keeps the frame parts together to allow the load carrier to be pulled up steps, up a slope, or up over a curb without having the wheels separate from the receptacle, but automatically releases, allowing the user to dump a load of material from the receptacle by pushing forward on the handle.
Abstract: An auxiliary dump box accessory is provided for combining with a conventional flatbed bale (of hay) loader, for effectively converting the flatbed bale loader and the underlying conventional truck into a dump truck. Thus the dump box accessory gives the flatbed bale loader alternative utility(ies) besides the standard utility of loading and transporting large cylindrical bales of hay, including among others all the utilities typically provided by dump trucks. The dump box rests on the flatbed for use in a conventional upright position. However, when the dump box is unloaded for storage during non-use, it is deposited onto a base support surface such as the ground in a position in which it is substantially inverted.
Abstract: An inflatable bag (17) for use in exhaust powered tippers is constructed from blanks of flexible air tight material using a side wall template (10) and end wall templates (11, 12). The blanks are made so that the finished bag when fully inflated assumes an oblique cone-like shape (17) with rounded ends (19, 20). The side wall material is preferably a fabric having waft and weft fibres of uniform tensile strength so that the tension in the side wall is in the longitudinal direction as the bag inflates in order to reduce the tendency of the bag to rotate on its couplings. The invention can be provided in kit form where the bag is coupled for limited movement to load transmitting end plate (21, 22) for retro fitting the bag to a vehicle.
Abstract: An improved cart to be towed behind a riding lawn mower for collecting grass clippings, etc. therefrom and also which can be used for strict utility purposes.

Abstract: A round bale trailer includes a trailer that travels in a hay field in the same direction that the field is normally worked to approach round hay bales in a direction perpendicular to the bales' axes. A U-shaped fork on the round bale trailer engages three sides of the bale. A closing arm on the fork closes to engage the bale on the fourth side. Continued motion of the trailer causes the fork and bale to rotate together 90 degrees about a vertical axis such that the fork closes to nest within a generally U-shaped frame. A hydraulic cylinder immediately operates to pivot the frame and fork to a vertical attitude, such that the bale rolls off the fork and onto the trailer. Pivoting the frame to the horizontal attitude automatically opens the fork by the use of a spring. All the bales are unloaded at one time by an unloading mechanism that tilts the trailer such that the bales roll off one side thereof.
Abstract: A dumpable utility trailer comprising a frame assembly, a container assembly rotatably connected to the frame assembly so as to permit rotation of the container from an upright position to an inverted position, and a latch assembly adapted to limit the rotation of the container assembly relative to the frame assembly.
Abstract: A sloped floor trailer which incorporates drain ports which are opened during trailer loading and which are sealed during trailer transportation, in order to retain the liquid. In addition to the foregoing features, I provide apparatus for heating the trailer side walls with the truck tractor exhaust to prevent freezing during inclement weather.
Abstract: The improved assembly includes a truck having a generally horizontal trailer frame supported on rotatable wheels. The upper surface of the frame preferably includes a dished portion adapted to receive the assembly's open-topped, curved container bin, and also includes spaced rollers rotatably supporting the bin above the bottom surface of the dished portion. An upwardly directed tilt link is pivotally connected to at least one end of the frame adjacent one side thereof and to the upper end of the bin adjacent the opposite side thereof. A ram, preferably hydraulic, is pivotally connected to the side of the frame at a point remote from the tilt link and extends upwardly to pivotally connect to the upper part of the bin. If desired, a pair of tilt links can be used at opposite ends of the frame, with the ram spaced therebetween. During extension of the ram, the bin initially rotates on the rollers, without lateral displacement, enabling side loading from low slung bucket arms.
Abstract: A dump trailer having a chassis with ground engaging wheels under one end, a heavy duty hoist on the other end and a dump body pivoted to the chassis at the wheel supported end and adapted to be elevated by the heavy duty hoist incorporates a floor structure in the body including longitudinal and transverse frame members and provides resilient cushions on each of the transverse frame members of the body where they rest on the chassis when the body is in normal transport position.
Abstract: A bale rack comprises an elongate horizontal frame mounted on wheels for movement along the ground, and a pair of bale supports extending along opposite sides of the frame. The bale supports are pivotable relative to the frame between a raised position, in which the bale supports serve to retain bales on the frame, and a load release position, in which the bale supports are downwardly and laterally inclined from the frame to allow a bale to roll from the frame to the ground. Latch mechanisms are provided for releasably retaining the bale supports in the raised positions, and counterweights are provided for urging the bale supports from the lowered positions to the raised positions, thus avoiding the use of springs, hydraulic devices or other relatively complicated mechanisms for this purpose.
Abstract: A dump apparatus comprising a base frame removably mounted on a rear body of a truck etc., a loading box rotatably mounted on the base plate, an inflatable bag provided between the loading box and the base plate and a hose for feeding exhaust gas from an engine into the bag to inflate the same and tip the loading box by the inflation of the bag.

The container portion normally rests on the inclined frame section of the support portion and extends from adjacent the lower end of the inclined frame section upwardly beyond the upper end of the upstanding frame section. The container portion also including a receptacle member with an open upper end and a cover member pivotally connected adjacent an edge of the open end of the receptacle member.
Abstract: A dual side-dumping truck and trailer combination utilizing a dolly-type trailer and a frameless material hauling bed. The bed is suspended on bunk assemblies mounted rotatably on bolsters on the truck frame and the trailer frame. Hinge mounting arrangements on the ends of the bunk assemblies enable selective tilting of the bed to one side or the other. The dolly-type trailer provides increased maneuverability and improved safety factor by enabling jackknifing while dumping.
Abstract: A dumping transport vehicle for harvested cotton bolls has the capacity to receive in its basket body two dumps from a large self-propelled harvester. An internal power-operated pivoted packer-divider panel of the vehicle enables compacting of the first dump received from the harvester against the dump-out side of the vehicle basket so that the second dump from the harvester can be adequately received in the vehicle basket. The packer-divider panel also enables a two-stage dumping of the contents of the fully loaded vehicle basket into a module builder which is unable to handle and pack the entire volume of harvested cotton in the vehicle basket in a single delivery or dump.
Abstract: A vehicle is shown having a hopper mounted thereon capable of dumping materials contained within the hopper over the end of the hopper or through the bottom of the hopper. Dumping over the end of the hopper is accomplished by lifting the front end of the hopper and sequentially pivoting the rear end of the hopper upon an initial pivot point and a subsequent pivot point in a manner which minimizes the risk of the vehicle capsizing by maintaining a low center of gravity. Dumping through the bottom of the hopper is accomplished through the use of a clam shell gate covering an opening in the bottom of the hopper. The vehicle may be interchangeably used as a rear dump vehicle or a belly dump vehicle, more safely used upon hazardous terrains, and still carry the maximum load capacity allowed.
Abstract: A dumping wheelbarrow capable of providing a forward tilt to the barrow while maintaining the legs of the wheelbarrow on the ground. The wheelbarrow has a frame which supports the barrow which frame has a wheel and a pair of legs together with a pair of extending handles. The barrow is pivoted at a forward barrow point and is caused to dump by the action of a hydraulic piston affixed at one end to the frame and at the other end to the bottom of the barrow.
Abstract: A dumping transport vehicle is provided for transporting picked or stripped cotton from a harvester back to the module. A large capacity dump box or basket features strategically located wire mesh panels to allow air to escape when the cotton is delivered into the dump basket so that the cotton will not boil out over the top of the dump basket and will properly settle therein. Additionally, the vehicle features improved geometry for the basket dumping cylinders in relation to the dumping pivot for the basket and the supporting wheeled frame so that the loaded device will be stable and will remain adequately stable when the cotton is dumped into the top of the module.
Abstract: A tip-up trailer with a hydraulically operated tipping body having a device for preventing the tipping body sticking up in the raised position. This is done by providing a back pressure to bear on the piston of a hydraulically operated ram to assist in the commencement of the lowering operation. Preferably this back pressure is provided in the ram which raises and lowers the tipping body.
Abstract: A portable barbeque grill having a coal-receiving member hingedly connected to a cover member rotatably mounted between a pair of inverted U-shaped side frame members. The hinge means between the cover member and the coal-receiving member mounts the coal-receiving member and cover member off center between the juncture of the rear legs and the bight portion of the inverted U-shaped frame members so that the coal-receiving member can rotate under its own weight to a position wherein coals and ashes can be readily removed from its interior. The coal-receiving member can be locked in a substantially horizontal position by retaining pins received through the juncture of the front legs and bight portions of the inverted U-shaped frame members and inserted into the coal-receiving member to preclude it from rotating.
