  • Patent number: 5136795
    Abstract: A snow plow assembly has a frame with a rear portion adapted for attachment to a motor vehicle and a blade assembly adapted for rotation about a vertical axis with respect to the front portion of the frame. Two ends of a chain are attached to the blade assembly on either side of the vertical axis. The middle section of the chain can slide in a track (e.g. an arcuate tube) attached to the frame. The yaw angle of the blade is adjustably controlled by sliding the chain with respect to the track. Means are also provided for adjustably securing the chain to the track after the desired angle for the blade has been obtained. In addition, the blade assembly can include means for permitting rotation of said blade about a horizontal axis. In this embodiment, two lever arms extend upward from the blade assembly on opposite sides of the vertical axis. The upper end of each lever arm is attached to one end of the chain.

  • Patent number: 4991323
    Abstract: A combined snow plow/winch device is provided which includes a mouldboard for plowing snow and a winch for moving loads, both simultaneously mounted to a front of a vehicle. The mouldboard is pivotally mounted to the vehicle for limited movement about a horizontal axis against a biasing member. The winch includes a cable receiving drum, a cable wound about the drum by rotation of the drum, and drive structure for rotating the drum. The winch is mounted to the vehicle above the horizontal rotation axis of the mouldboard. A fairlead is affixed to the mouldboard above and forward of the horizontal rotation axis. During operation of the winch to move objects, the winch cable passes through the fairlead and exerts a force on the mouldboard such that the mouldboard pivots forward against the biasing member, allowing the cable to be straightened between the drum and the object to be moved.

  • Patent number: 4976054
    Abstract: A snowplow leveling system is described for use on a standard plow mounting structure having a reversing table mounted to a plow blade system and rotatably mounted on a support frame. The support frame is pivotally mounted about a horizontal axis onto a motor vehicle which has an elevatable lifting point. The snowplow leveling device is mounted on the support bar of the reversing table. The leveling device may include two slider mechanisms mounted on support tracks located on opposite ends of the support frame of the reversing table. Positioning struts hingedly connect the slider mechanisms to the support frame. Additionally, a lifting chain connected at each end to the slidable mechanisms and in the middle to a lifting hitch attached to the support frame aids in maintaining the leveling position of the snowplow system of the present invention.

  • Patent number: 4962599
    Abstract: A quick connect-disconnect coupling is provided for snow plows and like devices. The coupling includes a hitch ear plate and a retaining ear plate preferably attached to the plow. The hitch ear plate has a configured gathering surface and the retaining ear plate has a hitch pin opening extending therethrough. A bracket arrangement preferably attached to the vehicle contains a spring biased axially movable hitch pin. The hitch ear plate positions the retaining plate so that its opening is in registry with the hitch pin when the plow is to be coupled to the vehicle. Rotation of the hitch pin allows the spring to axially move the hitch pin and snap the pin through the hitch pin opening to lock the plow to the vehicle.

  • Patent number: 4821436
    Abstract: A high-performance plow system to be attached to a pickup truck or similar vehicle. The plow blade can be angled across the plowing surface and with respect to the motion of the vehicle up to about 45.degree., it can roll to allow the blade to track changing pitch angles along the plowing surface contours. The blade has two protective mechanisms, the first one being an appropriately-designed rake angle scraper structure, disposed at the bottom edge of the plow blade, the second one being a mechanism which attaches the blade to an A-frame assembly (AFA) by pitch and shear pins. The shear pins break if too tall an object is hit and allow the blade to fall over the object. The pins allow 30 second removal/attachment of blade.

  • Patent number: 4658519
    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.

  • Patent number: 4369590
    Abstract: Scraper apparatus for being carried at the rear of a vehicle such as a light truck or the like includes an attachment frame adapted for being carried by the vehicle beneath its chassis thereof at the rear of the vehicle. A blade-carrying frame for carrying the blade at the rear of the vehicle is pivotally and detachably securable to the attachment frame at the rear of the vehicle by use of a securement frame or unit providing telescoping interengagement with the attachment frame, and pivotal interengagement with the blade-carrying frame to define a transverse pivot axis to permit pivoting of the blade-carrying frame upon the axis relative to the vehicle. A winch selectively raises or lowers the pivot-remote end of the blade-carrying frame under remote operator control. The blade is pivotally secured to the blade-carrying frame by a sleeve in which is rotatably journalled a shaft secured to the blade.
