摘要： Power adjusted bulldozing attachment for a tractor having a Cframe and a bullgrading blade thereon capable of pitching, tilting, and single and double angle angling. An intermediate region of the blade has a universal mounting to the front of the C-frame. Pairs of strut members incorporating power units are connected to the end sections of the blade and to the legs of the C-frame for pitching and tilting the blade. The blade is angled by shifting the struts by means of power pistons on the legs of the C-frame. Piston locks fix the struts at locking points on the frame legs so that the blade, formed of bisected sections, can have the sections swung similarly to single angles or oppositely for double angle contouring.

摘要： An axle adjusting mechanism for the dual front axle bars and the single rear axle bar of a combine harvester, wherein the ground clearance of the individual axles may be varied by relocating the axle supports on the combine chassis frame. Adjustment of the front axle bars is accomplished by unbolting the gearboxes or casings which carry the wheel drums and hubs from the chassis framework, effecting eccentric adjustments thereof, and then rebolting the same in such adjusted positions to the framework, thereby changing the elevation of the framework, and consequently the axle bars which are supported thereby. Adjustment of the rear axle bars is carried out in a similar manner by unbolting the rear axle bar support from the chassis framework and raising or lowering such framework, as the case may be, relative to the support and re-bolting it in its adjusted position. Since no gearing is involved, no change in the angularity of the rear axle bar is resorted to. In the case of front axle bar adjustment, one set of bolt holes on each axle bar supporting member is designed for selective mating register with two sets of bolt holes on the chassis framework, while in the case of rear axle adjustment, one set of bolt holes on the chassis framework is designed for selective mating register with two sets of bolt holes on the axle bar supporting member.

摘要： A straw chopper attachment of the type in which a deflector plate directs the straw toward and against a chopper blade rotor disposed within a hood and in which chopper blade wear may be compensated for by shifting the deflector plate toward the rotor to preserve a predetermined optimumm blade-to-plate clearance gap. The plate is pivoted within the hood for swinging movement toward and away from the rotor and the necessary adjustments may be made exteriorly of the hood without necessitating access to the latter.

摘要： A closed centre hydraulic control system for a track-laying vehicle comprises a pair of spool valves and a pair of variable relief valves. Each spool valve controls the supply of hydraulic fluid to the clutch and brake cylinders associated with a respective one of the tracks of the vehicle and is operable in three positions: a first position in which the brake is disengaged and the clutch is engaged, a second position in which the clutch is disengaged and the brake is disengaged, and a third position in which the clutch is disengaged and the brake is fully engaged. Movement of the spool valves from the second to the third positions is effective to increase progressively the pressure at which the relief valve relieves hydraulic fluid supplied to the associated brake cylinder, so that the brakes are progressively engaged during the movement of the spool valve from the second position to the third position.

摘要： A burning table having a pan with a sloping bottom terminating in a clean-out trough. The water level in the table is controlled by over-flow pipes, one of which is valved to permit lowering the water level below the grating which catches the torch cut parts and the other of which controls the maximum water level necessary for burning but which is manually removable to permit complete draining of the pan and clean-out trough. A spray header extends along the pan opposite the clean-out trough and sprays water at high pressure through nozzles to wash debris resulting from the burning operation into the clean-out trough upon closing the valved over-flow pipe for filling the pan to the maxium water level necessary for burning. Bars for supporting the plate to be cut are mounted to minimize warpage and damage from the flame and to be readily replaceable.

摘要： Frame-steered, all crawler tractor having articulated frame sections end-to-end, and crawler tracks provided on one section which can be retracted from those confronting crawler tracks in tandem therewith which are provided on the other section. In driving the tractor into a turn I thus afford a retractive endless track, say a rear track which, as I make the turn, takes the inside of the turn, but at all times keeps its distance from the front track at the inside of the turn. There is no interference because the retractive track, in the case of the rear track for instance, does not try to climb up on the front track, and the resulting close-coupled articulated vehicle is not train-like in length.

摘要： A plurality of elastomer means of varying deflection rates arranged such that vertical shock and dampening is achieved by a first low and a second high deflection rate means, lying in the same parallel plane. Both elastomer means have generally flat top and bottom faces, the second elastomer means being thinner than that of the first and positioned in close proximity thereto.
