Abstract: A mounting for a drive mechanism of an elevator used in a carry-type earthmoving scraper wherein the elevator assists in loading material into the scraper. The drive mechanism includes provision for absorbing torsional vibrations generated by flights of the elevator striking material being loaded and, coincident therewith, axial alignment is maintained between driving and driven members of the drive mechanism.

Abstract: An operator's compartment mount which isolates the operator's compartment from the vehicle frame. The operator's seat mount and roll-over protective structure rear mount are secured directly to the vehicle frame. The front portion of the roll-over protective structure is mounted directly to the operator's compartment and the rear portion is isolation mounted to the vehicle frame.

Abstract: A conveyor drive roller mounting system for controlling misalignment of the drive roller by mounting an end of the conveyor drive roller on a resiliently mounted torque arm which permits the drive roller to align with the conveyor path of movement.

Abstract: An instrument panel cover pivotally connected to the vehicle dashboard and adapted to be folded upon itself into a position above the dashboard to minimize the storage space required by the panel cover when not in use and to eliminate obstructions in the operator compartment or the operator's field of vision.

Abstract: A control lever assembly mounted on a panel including a mounting bracket adapted to be mounted to one side of the panel over an opening therein and a pivot pin fixed to the bracket having its axis disposed in a plane parallel to the plane of the opening in the panel. A rotary bearing device surrounds the pin and is journaled thereon to rotate about the pin axis. A handle is fixed to the bearing device and extends through the opening in the panel with the distal end portion of the handle being disposed on the opposite side of the panel. A centrally-apertured, flexible seal member surrounds the handle and is disposed between the bearing device and the mounting bracket to seal the assembly to the one side of the panel.

Abstract: An elevating scraper comprises a bowl which can be hydraulically raised and lowered, a motor-driven elevator which can be hydraulically raised and lowered, an ejector hydraulically movable forwardly from an aft position to eject material from the bowl and a hydraulic control system for operating the aforesaid components.

Abstract: A motor scraper has a dozer-type ejector blade which is forwardly movable to eject earth from the scraper bowl by an operating mechanism which includes a movable carriage having three hydraulic rams mounted thereon. The ram cylinders are rigidly connected in parallel physical arrangement on the carriage. The piston rods of two rams are pinned to the ejector blade and the rod of the remaining ram is pinned to the scraper frame. The blade and carriage are initially disposed in their rearward positions. To move the blade forward to eject earth from the bowl, pressurized hydraulic fluid is supplied simultaneously to all ram cylinders to initially cause the said two rams to extend fully and move the blade part way forward (while the said one ram causes the carriage to remain stationary) and to then subsequently cause the said one ram to extend fully and move the carriage forward and thereby cause the blade to move all the way forward.
