  • Patent number: 10000901
    Abstract: The snow shovel comprises a shovel with a de-icing system and a light. The shovel may comprise a plurality of wheels at the bottom rear side of the blade. The light is battery operated and illuminates the work area in front of the shovel. The de-icing system comprises a fluid system, a heat system, or both.

  • Patent number: 8381420
    Abstract: A material dispenser that may be used with a snow removal machine is comprised of a container, broadcaster actuator, and broadcaster in one embodiment. The material dispenser allows the operator to broadcast dry treatment material from a container mounted to the snow removal machine regardless of whether the precipitation engaging member of the snow removal machine is operating. The broadcaster actuator operates to cause the treatment material to be placed on or adjacent the path of the snow removal machine. The broadcast actuator may be positioned on a handle member of the snow removal machine so that it is convenient for the operator to engage the broadcast actuator while operating the snow removal machine or when the precipitation engaging member is not removing precipitation. A slide gate may be used to throttle the volume of treatment material exiting the container, and a slide gate actuator may be remotely mounted.

  • Patent number: 6003916
    Abstract: A snow-removal, such as a snow shovel, snow plow and the like, includes a heated blade. The snow-removal device might also provide a selection of temperature settings for the heated blade. The snow-removal device at least fluidizes the snow when the blade slices into it, whereby the fluidized snow lubricates the interface region between the blade and the snow, diminishing the physical effort required.

  • Patent number: 5729857
    Abstract: A snow removal device for rapidly removing large amounts of snow from the top surfaces of an automobile. The snow removal device includes a mitt element that receives a person's hand and a portion of the arm to a point in between the elbow and the shoulder. The mitt element is affixed to the rear surface of a plow structure, wherein the mitt element retains the hand so that the palm of the hand faces the rear surface of the plow structure. The mitt element and the plow structure combine to retain a person's arm in a manner that prevents the arm from bending at the elbow. The plow structure has a substantially planar front surface that displaces snow as it moves across the top surfaces of an automobile. The bottom of the plow structure is configured so that is can conform to the changing contours of the automobile without scratching any finished surface that the plow structure may encounter.

  • Patent number: 5706592
    Abstract: A snow removal push board and snow barrow. More specifically, the invention is a snow push board made up of a generally rectangular board with handles on one side and a scraping edge directly opposite the handles. The push board is operated by grasping the handles in front of the waist and allowing the board to be on an approximately forty-five degree incline from the user's waist to the ground while pushing the scraping edge along the ground. The snow barrow includes a board having a scraping edge and generally triangular sides. The snow barrow has handles for the user to grasp and push the barrow with two large wheels in the rear and two smaller wheels in the front of the barrow for maneuvering. The snow barrow also has structure for dispensing salt using either a vertical pinwheel or track dispersement axles in between the rear wheels of the barrow. The amount of salt dispensed can be controlled by adjusting a gauge.
