  • Patent number: 6513267
    Abstract: A snow removing machine equipped with a snow removing plate is disclosed. The snow removing plate is mounted to a front portion of a vehicle body which forms part of the snow removing machine. An operating handle having grip portions is mounted to a rear portion of the vehicle body and obliquely extends upward. A battery, an electric motor and a power transmission mechanism are located below a linear line intersecting between an upper end of the snow removing plate and the grip portion. This causes the battery, the electric motor and the power transmission mechanism to be located below a view line of an operator when he looks at the snow removing plate, avoiding the view line from being disturbed to allow the operator to look at the upper end of the snow removing plate in his working attitude for thereby providing ease of operation of the snow removing machine.

    Abstract: A plow blade is described which has first and second sections, e.g., a moldboard and a trip board, which are rotatable with respect to each other and maintained in a desired angular relationship with respect to each other via an elastic torsion joint. The elastic torsion joint includes an elongated inner member at least partially surrounded by an elongated outer sleeve. Resilient elastic cushioning wedges (e.g., elastomeric wedges) are situated between the inner member and outer sleeve in such a manner that rotation of the inner member with respect to the outer sleeve compresses the cushioning wedges and elastically resists rotation. The inner member and outer sleeve are respectively affixed to the moldboard and trip board (or vice versa) so that when the trip board strikes an obstruction and is biased with respect to the moldboard, the elastic torsion spring resiliently yields, and then causes the trip board to snap back to its original position with respect to the moldboard once the obstruction is removed.

The guide member has a downwardly facing air inlet at a fore end positioned forward of the snow plow blade to intercept and capture without interruption an air stream which, by reason of forward movement of the vehicle, is directed toward the leading concave surface of the snow plow blade, then upwardly along that surface, and through a rearwardly facing air outlet at the aft end positioned aft of the snowplow blade. An air stream containment passage intermediate the air inlet and the air outlet is effective to receive the air stream from the air inlet and redirect it toward the air outlet from whence it is exhausted away from the snow plow blade and toward the radiator of the motor vehicle.

  • Patent number: 5782016
    Abstract: A scraper apparatus is disclosed for mounting under a body of a truck. The apparatus includes a table having a forward and a trailing end. The forward end is pivotally secured to the body of the truck. The arrangement is such that the table is permitted to pitch relative to the body of the truck. A bearing is secured to the table and is disposed between the forward and the trailing ends. A mold board scraper is disposed below and supported by the table with the mold board scraper being rotatably secured to the table by the bearing. A hydraulic cylinder secured to the mold board scraper rotates the scraper relative to the table and an actuator pivots the table for controlling the pitch of the table and the mold board secured to the table so that scraping of snow, ice and gravel regardless of the level thereof relative to the truck is permitted.

  • Patent number: 5762147
    Abstract: This invention is a simple, safe, and inexpensive beam structure for tractor forward mounting of a blade (24). A pivot plate (11) is mounted at the tractor lower mid-section. Parallel beams (12) are positioned through the pivot plate (11) and extend beyond the tractor front and rear. The aft ends of beams (12) are attached to the tractor 2 or 3 point rear hydraulic lift arms (26). The forward ends of the beams (12) are the blade primary attachment points. A counterweight (13) attached rearward will raise the blade (24) when the tractor 2 or 3 point rear hydraulic lift arms (26) are lowered. The blade (24) is lowered by raising the 2 and 3 point rear hydraulic lift arms (26), thereby, giving effective vertical control of the front mounted blade.

  • Patent number: 5729919
    Abstract: The present invention comprises one or more anti-drift stabilizers mounted on the leading edge of a snow plow's blade. These stabilizers are mounted at an angle that is in the same direction as the angle of the snowplow in relation to the plow truck. As snow or other media is channeled to one side of a plow blade it exerts a force in the opposite direction thus tending to cause a plow to want to knife or drift in a direction opposite where the snow or other media is being deposited by the blade. As snow or other media passes over the surfaces of the stabilizers it exerts pressure that is opposite to, and counteracts the knifing action created at the emptying end of the plow by the accumulation of snow. The result of this is that the plow can be operated safely without the need to make constant corrections for the knifing and without the added danger of the inattentive operator being pulled from the roadway or into oncoming traffic and causing property damage or personal injury.

  • Patent number: 5720122
    Abstract: A plow blade assembly for clearing a surface during a plowing operation comprises a plow blade having a front and rear surface and a lower edge. The plow blade is pivotally supported on a support frame for movement between a forward and a retracted position. The plow blade is normally resiliently retained in the forward position. An actuator is flexibly connected to the plow blade so that the position of the blade can be selectively varied and maintained at a location between the forward and retracted positions.

  • Patent number: 5715613
    Abstract: The present invention relates to a blade which can be removably secured to the bottom of a conventional snow plow. The blade enables the operator of the snow plow to collect snow in either the forward or rearward running directions of the snow plow. This blade has a construction which specifically enables the blade to be employed beneath a conventional snow plow. More specifically, the blade of the present invention includes an angularly positioned forward plow surface and a rearward plow surface. These two plow surfaces are interrelated by way of a number of equally spaced reinforcing ribs. Securement means are included to enable the forward plow surface to be removably secured to the bottom edge of a conventional snow plow.

  • Patent number: 5615745
    Abstract: An all terrain vehicle having a vertically movable blade at the forward end thereof is described wherein the vertical movement of the blade is controlled by a lift handle positioned rearwardly thereof and which is pivotally mounted on a lift handle bracket. The lift handle has a locking pin mounted thereon which is positioned rearwardly of the rearward end of the lift handle bracket when the blade is in its raised position. When it is desired to lower the blade, the lift handle is pivotally moved with respect to the lift handle bracket to disengage the locking pin with respect to the rear end of a lift handle bracket. A rub block is positioned on the outer surface of the lift handle bracket for engagement with the lift handle to prevent the locking pin from wearing or cutting a groove in the lift handle bracket.

  • Patent number: 5603172
    Abstract: A plow blade comprising a forward facing longitudinally curved major portion and a minor blade resiliently and pivotally mounted on the major portion and being disposed between the major portion and the surface to which the plow is applied. Also included in the preferred embodiment is a `reversing` cylinder which is selectably operable to apply a force to urge the minor blade into a selectably rearward angle without inhibiting the resilient movement of the lower portion to respond to surface obstacles by deflecting into a further rearward position. Also provided of the present invention are selectable intermediate minor blade positions, such as perpendicular to the surface, to facilitate removal of residual surface material, e.g. packed snow and ice. Alternate embodiments include a retrofit kit applicable to existing plows to provide the features of the present invention.
