Abstract: A winged plow for moving snow or other materials with a vehicle has a support frame pivotally connected with one end of a plow vehicle. An elongated plow blade having two opposing ends is pivotally connected with the terminal end of the support frame for generally horizontal rotation between a centered position with the plow blade oriented generally perpendicular to the support frame and an angled position with the plow blade rotated substantially away from the centered position. One of a pair of plow blade wings is pivotally connected at each of the opposing ends of the plow blade for rotation between a closed position in which the wings project generally forward, the wings and plow blade defining a generally U-shaped assembly, and an open position in which the wings project in generally opposite directions, away from each other, effectively extending the length of the plow blade.

Abstract: A hinged snowplow includes a T-shaped support frame for attachment to a vehicle, the support frame having a free end. A cowling having a pair of extending plow blades pivotally secured thereto, is pivotally secured to the free end so as to pivot in a generally vertical plane about the free end. The cowling has a first stop engageable with the support frame to limit pivotal movement of the cowling about the frame to a first or normal plowing position. A second stop on the cowling is engageable with the support frame to limit the pivotal movement of the cowling about the frame to a second or tipped position. A trip bias mechanism between the frame and the cowling biases the cowling and plow blades to the first position in which the blades are normally positioned for plowing. The cowling and blades are rotated against the trip bias mechanism toward the second, tipped position when the blades hit an obstacle.

Abstract: Support apparatus for supporting logs, boards and other work pieces to be cut either transversely or lengthwise, as well as for supporting a chain saw by its blade for performing the cutting. A support platform includes a top surface, preferably inclined downwardly toward an operator position, and a restraining rail to hold the work pieces in position for cutting. A spring-biased, rotatable axle mounts the chain saw by the free end of its blade for pivotal movement along one side of the platform to transversely cut work pieces. Alternately, a rigid saw support holds a chain saw vertically upright with its blade plane parallel to the direction of elongation of the work pieces for rip cutting. An outwardly extending, side support, opposite the saw support, movably mounts a second platform for additional support and movement of long logs, boards or other work pieces.
