Abstract
The lateral plough is attached to the hitch assembly of a grader or snow plough and is used to remove selected segments of an elongated pile of gravel or snow. The plough has an arcuate blade for pushing the gravel or snow forward. A gate is attached by a hinge to the outer end of the blade for preventing the gravel or snow from exiting from the blade as the grader or plough advances. The angle of the blade may be adjusted by shortening or lengthening the effective length of a chain which extends from the outer edge of the gate to the blade.
Claims7
A lateral plough adapted to be attached to a hitch assembly of a motor vehicle for removing selected segments of an elongated pile of particulate material comprising:
- a blade having an inner end adapted to be in proximity to said motor vehicle and an outer end adapted to be remote from said vehicle, said blade adapted to swing from an operative position in which its ends are at approximately the same elevation and said blade is in position to push said particulate material forward to an inoperative position in which said outer end is higher than said inner end;
- a gate pivotally disposed at the outer end of said blade and having an outer edge which swings toward said blade to a closed position in which said outer edge is adjacent to said blade and which swings away from said blade to an open position in which said gate prevents said particulate material pushed by said blade from exiting from the blade as said plough advances;
- resilient means for biasing said gate open when said blade is in said operative position but being opposed and overcome by the force of gravity when said blade is in said inoperative position thereby allowing said blade to close.
A lateral plough adapted to be attached to a hitch assembly of a motor vehicle for removing selected segments of an elongated pile of particulate material comprising:
- a blade having a longitudinally extending axis and having an inner end adapted to be in proximity to said motor vehicle and an outer end adapted to be remote from said vehicle, said blade adapted to swing from an operative position in which its ends are at approximately the same elevation and said blade is in position to push said particulate material forward to an inoperative position in which said outer end is higher than said inner end, said blade having an end wall at the outer end thereof, said end wall extending laterally from the longitudinal axis of said blade;
- a gate pivotally attached to said end wall for preventing said particulate material pushed by said blade from exiting from the blade as said plough advances, said gate being pivotal from an open position in which said gate prevents said particulate material pushed by said blade from exiting from the blade as said plough advances to a closed position in which said gate is adjacent to said blade;
- resilient means for biasing said gate open when said blade is in said operative position but being opposed and overcome by the force of gravity when said blade is in said inoperative position thereby allowing said blade to close.
An assembly for removing selected segments of an elongated pile of particulate material including:
- a frame adapted to be attached to a hitch assembly of a motor vehicle;
- a lateral plough having opposite ends, one said end being pivotally connected to said frame and the other said end terminating at an end wall, said plough having an arcuate blade for pushing said particulate material and having a gate pivotally attached to said end wall;
- and means for causing said plough to pivot about said frame with resulting raising and lowering of said end wall;
- said pivotal connection between said plough and said frame comprising a stud which extends from said plough to a plate, a pair of first rods extending from said plate and being rotatably mounted to a trunnion and a pair of second rods which are fixed to said trunnion and to said frame.
