Abstract

A snow gate attachment to be used at the end of a snow plow blade, adapted when in operation to prevent snow from discharging from the end of the blade, thereby preventing ridging when crossing driveways and the like. The gate attachment has a frame with a bracket adapted to be mounted to the end of a plow blade, the gate member proper pivotally mounted to the frame, and actuating means mounted on the frame for actuating the pivoting movement of the gate member between an operating position and an inoperative position.

Claims

1. A snow gate attachment for a plow blade provided on a vehicle comprising a frame, bracket means mounted on the frame for securing the frame to the free end of a plow blade, a gate member pivotally mounted to the frame, actuating means positively actuating the pivoting movement of the gate member between a first position and a second position whereby the gate member, when in the first position, will be in a horizontal position when mounted with a plow blade and extending forward of the blade to block the discharge of snow from the plow blade, the gate member being pivotable in a vertical plane parallel to the axis of the vehicle on which the plow blade is mounted for trapping snow, and a second position whereby the gate member will be clear thereof and allowing the snow to be discharged from the plow blade, the frame and gate member being mounted rearwardly of the plow blade.

2. An apparatus as defined in claim 1, wherein the frame includes flange means adapted to be mated with a similar flange means at the end of a plow blade, shaft means journaled to the frame and fixed to the gate member, actuating means mounted to the frame at one end thereof and to lever means fixed to the shaft means at the other end thereof for rotating the shaft means and thus pivoting the gate member between the first and second positions, the frame and gate member being mounted rearwardly of the plow blade permitting a clear discharge of the snow from the plow blade when the gate member is in its second position.

3. A gate member as defined in claim 2, wherein the gate member is an elongated rectangular member mounted at one end to the shaft means and normal thereto.

4. An apparatus as defined in claim 3, wherein the frame includes a guide wall in a vertical plane adapted to be juxtaposed with the gate member and for supporting said gate member in its vertical plane.
