Rotor Shaft Adjustable Relative To Direction Of Travel Patents (Class 37/247)
  • Patent number: 7997016
    Abstract: A self-propelled snow remover has a machine body, a snow-removing implement mounted to a front part of the machine body for undergoing rolling and vertical movement relative to the machine body, and an operating unit mounted to a rear part of the machine body. An alignment operating member is mounted to the operating unit for rolling and vertically moving the snow-removing implement. The alignment operating member is disposed on one of opposite sides of a widthwise central line of the machine body. A return operating member is mounted to the operating unit for automatically returning the snow-removing implement to a predetermined reference position. The return operating member is disposed proximate to the alignment operating member at a position closer to the widthwise central line of the machine body than the alignment operating member and further towards the rear part of the machine body than the alignment operating member.

  • Patent number: 7712233
    Abstract: To prevent or minimize bridging of material to be dispersed within a containment vessel, a rotatable auger is positioned in close proximity to a curvilinear inner wall surface of the vessel. The auger has an axis that moves parallel to the curved wall surface in a manner such that the auger flights maintain a close working relationship relative to the curved wall surface as the auger is positioned for movement therealong. A spreader apparatus is positioned to receive material dispensed through the vessel outlet port to broadcast the dispensed material externally of the vessel.

  • Patent number: 7165345
    Abstract: The automation mechanism has of three rubber discs, two of which are connected to two swiveling brackets. The brackets are directed by two cables and two cable levers, each one connected to each handlebar. The swivelling brackets consist of two rubber discs that make contact to the center disc at the left side of the shroud. This center disc is connected to the rotating snow auger inside the shroud, which is the driving force for this invention. When one of the rubber discs makes contact with the rotating rubber disc at the center, it rotates a drive chain that is connected to a sprocket near the discharge chute. The sprocket rotates a clutch that rotates a worm gear, and in turn, rotates the discharge chute. Once the discharge chute reaches its maximum rotating limit, the clutch disengages by slipping. The operator can move the chute either right or left by pulling on either the left or right lever on the handlebars, while operating the snow blower at the same time.

  • Patent number: 6810609
    Abstract: A snow tiller (10) suitable for grooming ski hills, trails, or other areas, provides an adjustable profile tiller assembly. The snow tiller (10) is preferably pulled by a tracked vehicle (12) and has a tiller assembly formed of a plurality of tiller subassemblies (56,58). By varying the respective orientation of the tiller subassemblies (56,58), the snow tiller (10) can selectively provide coactive, level, convex, or more complex snow profiles depending upon the tiller configuration, snow conditions, and the intended uses. The snow tiller (10) also provides a control system to substantially maintain a selected snow profile while selectively permitting individual tiller subassemblies to float, thereby reducing the possibility of damage. The assembly can simultaneously provide an automatic release mode to protect the equipment from damage.

  • Patent number: 6756750
    Abstract: An electric vehicle driven by a pair of left and right electric motors is provided. The vehicle includes a controller for controlling the start of the vehicle. The controller performs such control as avoiding brake drag caused by the operation of the electric motors before the elimination of the braking of a pair of left and right parking electromagnetic brakes.

  • Patent number: 6637134
    Abstract: Snow track preparation machine with mill installed in a revolving manner and including a pump driven by a power source, a hydraulic motor connected to the pump on the delivery side and the return side, an actuator supported on the assembly frame and realized for rotation of the mill and driving wheels. The power source is made up of a motor (2) which drives the driving wheels (5,6) and the pump (9) and actuator (16) are influenced by a control unit (17) connected to a sensor of motor rpm nD, to a sensor of the rpm of the driving wheels na1 and na2, to a sensor for the hydraulic motor of the mill and an actuator path sensor with the control unit (17) connecting the magnitudes detected by the sensors by means of an algorithm and controlling on the basis thereof the pump (9) and the actuator.

  • Patent number: 5398431
    Abstract: A snowthrower (20) including an improved impeller (50) which has an "open center" configuration and which is substantially made from a single piece of plastic. Impeller (50) includes a pair of curved blades (60) which are supported, braced and stiffened by a plurality of "spiders" (62, 64, 66, 68, 72, 74, 76 and 78) which form recesses for receiving a shaft (42) which spans between the side walls (36) of the snowthrower housing (22). Curved blades (60) of impeller (50) extend transversely between a pair of somewhat circular plates (52, 54). Plates (52, 54) preferably include teeth (54b, 54c, 52b, 52c) which help to break up snow and ice and assist in propelling snowthrower (20).

  • Patent number: 5077920
    Abstract: A power broom assembly includes a vehicle, a rotatable broom mounted to the front of the vehicle, and an airblast assembly mounted to the front of the vehicle above the broom to suck up an overspray of material which has been swept up by the broom. An airblast assembly for use in the power broom assembly includes a casing, a cross flow blower in the casing, and at least two outlets in the casing which are selectively openable and closeable by flexible wall portions which are movable radially inwardly and outwardly to substantially change the inner contour of the casing. A drive system of the power broom assembly includes a first transmission unit which has first and second output shafts, and a second transmission unit which includes an input shaft. At least the first and second output shafts of the first transmission unit and the input shaft of the second transmission unit are aligned along a single axis.

  • Patent number: 4480397
    Abstract: This snowblower equipment includes a snowblower unit arranged to be readily and removably attached to the rear frame of a truck, and a truck so equipped, such that the rear frame or platform of the truck remains free for conventional trucking, either with or without the snowblower unit attached to it. This snowblower equipment includes a pivot section attached to the rear frame of a truck and at the edge of it, and having a lifting mechanism with upright pivots around which a second pivot section swivels bodily with the snowblower unit fixedly secured to it. The snowblower unit may thus selectively swivel between a lateral projecting position and a rearward projecting position relative to and outward of the rear frame.
