Carrying Excavating Tool Patents (Class 37/240)
  • Patent number: 6367176
    Abstract: The rotary snow blower plow with a plow worm (18) which delivers the snow and a fan blower (19) which throws the delivered snow. The fan blower (19) is located on a line with the plow worm (18). The fan blower (19) and the plow worm (18) can be mounted on a common shaft (23) so that they rotate with the same angular speed. The rotary snow blower plow is characterized by high efficiency since the flow of snow need not be deflected by 90 degrees. It is especially suited for clearing of side walls and preparation of half pipe courses.

  • Patent number: 6164349
    Abstract: A machine includes a number of saw blades rotatably supported on a spindle for cutting a timber into a number of panels. One or more feeder rollers may feed the timber through the saw blades. A number of cutter elements are disposed between the saw blades for forming a gap between the saw blades and for machining a rounded edge to each of the panels. A milling cutter is rotatably supported in front of the saw blades and includes one or more milling blades for machining the timber to form a number of rounded bulges before the timber is cut into the panels by the saw blades.

  • Patent number: 5940995
    Abstract: A shaping apparatus for the working/maintenance of a snow-boarding half-pipe. The apparatus comprises a framework with a curved portion serving to support and guide a pair of drive chains actuated to run over an endless path. To the drive chains are attached scraper elements adapted to extend perpendicularly outward from the endless path of the chains, the scraper elements being designed to cut away snow from the half-pipe surface to be shaped. The scraper elements further incorporate elements serving to move the detached snow along the shaped surface and to smooth the surface. The apparatus is intended for attaching to a self-actuated vehicle, to be powered therefrom.

  • Patent number: 5561921
    Abstract: A vehicular apparatus which is adapted for removing fluids including snow and/or ice and de-icing or anti-icing liquids from a surface as the apparatus traverses the surface. The apparatus comprises: a first container for receiving a first portion of the fluids removed from a zone of the surface; apparatus for collecting and transferring the first portion of the fluids from the zone to the first container; a second container for collecting residual fluids remaining on the zone of the surface after the first portion is removed; a tank for containing water and a diaphragm pump for pumping water from the tank through nozzles at high pressure on the zone of the surface to loosen the residual fluids or make them airborne; and an air sweep connected in fluid communication with the second container for drawing or sweeping the loosened residual fluids and water into the second container concurrently with impinging high pressure water on the surface.

  • Patent number: 4827637
    Abstract: The apparatus for clearing a trafficked surface such as a road, express highway and airport runway of snow, slush, water, dirt and the like comprises a framework in which two rotatable drums are mounted and around which a conveyor belt for the material to be cleared movable transverse to the direction of travel or inclined in the operating location is guided. The conveyor belt is movable into a position inclined at an acute angle with respect to the normal of the trafficked surface. One of two strands of the conveyor belt is contactable on the trafficked surface while the other oppositely movable strand of the conveyor belt is liftable from the trafficked surface.
