Abstract: A quarter frame end dump trailer has one or more resilient members placed in its drag link in order to permit the use of an air ride suspension in a tandem axle, spread axle or other multiple axle configuration.

Abstract: An elevating system elevates a payload platform between a first position and a second position, such elevating system having a stowed position, an operational position, and a fully-deployed position. The elevating system includes an extendable actuator rod pivotably mounted on a frame and a link pivotably mounted to the extendable actuator rod and pivotably mounted to the payload platform. The extendable actuator rod and the link are moved from the stowed position to the operational position by increasing the length of the extendable actuator rod from a first length to a second length. The extendable actuator rod and the link are moved from the operational position to the fully-deployed position by increasing the length of the extendable actuator rod from the second length to a third length.

Abstract: A trailer for a dumping vehicle having a front and a rear for unloading of materials. The trailer includes a tapered bottom floor extending between the front and the rear, the bottom floor at the rear being wider than at the front. A pair of opposed sidewalls extend from the bottom floor, each sidewall at an obtuse angle to the bottom floor.

Abstract: An amusement park attraction having a dynamic ride vehicle for executing a sequence of distinct motion patterns and for providing unique ride experiences in the amusement park attraction or other environment. The ride vehicle includes a movable chassis and a body having a passenger seating area. A motion apparatus, including Ycomputer controlled actuators, imparts motion to the body along a plurality of axes independent of any motion of the chassis as it moves along a path in the amusement park attraction. As the vehicle travels along the path, articulation of the body and appropriate steering of the vehicle enables the vehicle to execute, in cooperation with the motion apparatus, a sequence of distinct motion patterns. Execution of the motion patterns enhances the passengers' sensation of vehicle movement that is actually taking place, as well as the sensation of a realistic moving ride vehicle experience that is actually not happening.

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 tree transport trailer (10) which is adapted for use with hydraulic tree spades without additional jacks or reinforcement, comprises a frame (12) and a plurality of carriers (34 and 36) mounted for pivotal movement about offset axes (40, 44) between a loading/unloading position in direct stopped engagement with the underlying surface and a transport position out of engagement therewith. An actuator (46) is provided for effecting pivotal actuation of the carriers. A trailer (80) incorporating a second embodiment with independently actuated pivotal carriers (96) is disclosed.

Abstract: A self-loading dump body truck comprising a vehicle having a frame, first and second cross members mounted on the frame, the first cross member being positioned near the rear of the vehicle and the second cross member being positioned forwardly of the first cross member, a cargo box pivotally connected to the first cross member and being supported by the second cross member in a lowered positioned, and inverted U-shaped boom member pivotally connected to the first cross member, the cargo box and the boom member having a common pivot axis, a hydraulic cylinder for pivoting the boom member with respect to the frame, a slide connected to the boom member and slidably engaging the cargo box for movement with respect to the cargo box as the boom member is pivoted, and a connecting arrangement for selectively connecting the slide to the cargo box for pivoting the cargo box as the boom member is pivoted.

Abstract: An apparatus for collecting litter from roadways and grounds includes a ground engageable rotating drum with easily removable and replaceable fingers which slip in and out of channels mounted on the drum. A spring finger assembly rotates against the drum to aid in litter pickup and to strip material from the drum and deposit same on a conveyor. The conveyor directs the litter into a hopper, which, when full, is lifted by an arrangement of pivots and linkage arms to raise upwardly, then swing rearwardly and tip to dump the litter into a suitable receptacle.

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.

Abstract: A door linkage for a side dump railroad car operable to automatically lower the door on the low side of the car when the car body is tilted to dump its contents thereof.

Abstract: A generally rectangular lifting stabilizer arm is pivotally connected on opposite sides at one end thereof between a pair of stationary truck frame members and is movably connected on the outer free end by a pair of slide track type connections to oppositely disposed longitudinal members of a dump frame that is pivotally connected to the stationary truck frame members, and a hydraulic cylinder-piston assembly is pivotally connected on one end to a central portion of the rectangular lifting stabilizer arm and is pivotally connected on the opposite end to the dump frame, whereby actuation of and minimal travel of the cylinder-piston assembly pivots the lifting stabilizer arm and cylinder-piston assembly, and pivots the dump frame in different arcs from horizontal positions above the truck frame members to a raised dump position.
