Abstract

A device for selectively controlling the height of a snow blower auger housing relative to the surface from which snow is being removed. Glide wheels are attached to the sidewalls of the auger housing of a snow blower to support the snow blower auger housing and to provide for clearance between the scraper blade and the surface to be cleared of snow. A glide wheel assembly may be fixably appended to the side walls of the auger housing and provides for easily adjustable height to set and maintain the height of the scraper blade in the auger housing at a desirable distance above the surface.

Description

    FIELD OF THE INVENTION
  • The present invention relates to devices for snow blowers, and more particularly, to a glide wheel assembly for maintaining proper blade-ground clearance during operation of self-propelled snow blowers. The glide wheel assembly may be configured for use on snow blowers for stand-behind operation that have an engine situated above two drive wheels and an attached front-mounted auger housing.
  • BACKGROUND OF THE RELATED ART
  • Self-propelled snow blowers may be configured for stand-behind operation and have an engine situated above two drive wheels and an attached front-mounted auger housing. To ensure effective operation and snow removal, the operator must maintain a proper clearance between the auger housing horizontal bottom leading edge (conventionally called a scraper blade) and the surface from which snow is being removed. The proper adjustment of this clearance is critical because if the scraper blade clearance above the surface is excessive, the snow is not cleanly removed. If the clearance above the surface is insufficient, the scraper blade may dig into the surface, making operation of the snow blower difficult. In addition, the front of the auger requires physical support during operation to carry some of the weight of the device.
  • Wear shoes or skid shoes have been developed for snow blowers or similar devices that maintain the proper clearance between the scraper blade and the ground surface. For example, U.S. Pat. No. 2,768,453 to Adams describes a wear shoe mechanically affixed by bolts to a snow scoop assembly. To compensate for different plowing conditions or to account for plate wear, the height of the snow scoop above the surface to be plowed is adjusted by an operator by loosening the bolts and increasing or decreasing the amount of the wear shoe projecting below the bottom of the snow scoop. The bolts are then tightened, mechanically fixing the wear shoes to the snow scoop assembly.
  • U.S. Pat. No. 5,438,770 to Miller describes a track-driven snow blower with pivot wheels that can be lowered to assist in turning corners. The pivot wheels do not set the height of the auger housing during snow removal. Miller shows skid shoes on the auger housing to support the front of the auger housing during snow removal and to set the distance between the lower leading edge of the auger housing and the surface to be cleared of snow.
  • U.S. Pat. No. 4,441,266 to Westimayer describes a skid shoe detachably mounted to the side of the snow blower auger housing such that the skid shoe mounting assembly can be easily reassembled to a plurality of preset heights. Normal wear of the skid shoes requires that they be adjusted frequently to prevent digging of the lower leading edge of the auger assembly into the plowed surface. Replacement of the skid shoes is required when the skid surface is worn away. Another characteristic of skid shoes is that they skid over only minor irregularities in the surface. When skid shoes encounter larger obstacles during plowing, such as cracks or ridges of ice, forward movement can be abruptly halted, making operation awkward and physically strenuous to the operator.
  • In light of the foregoing, a need exists for an assembly that supports a snow blower auger assembly, that provides selective control over the height of the auger leading edge above the surface to be cleared of snow, and that does not experience the excessive wear of skid shoes and the resulting required frequent adjustments to them. Similarly, it would be advantageous to provide a means of support for the auger housing that could climb over larger obstacles rather than colliding into them and stopping forward motion of the snow blower.
  • SUMMARY OF THE INVENTION
  • The present invention is directed to providing a glide wheel means to support the snow blower auger housing and to provide for clearance between the scraper blade and the surface to be cleared of snow. The use of glide wheels rather than skid shoes reduces the friction between the auger housing and the ground. The wear of the wheels is negligible as compared to the wear experienced by skid shoes. The height difference between the scraper blade and the bottom of the wheel remains constant, preventing the scraper blade from digging into the surface to be cleaned. The wheels are located so that the height of the scraper blade above the bottom of the wheels is between about 0.0 cm and 2.0 cm. Glide wheels have the further advantage over skid shoes in that they roll over obstacles that skid shoes would collide with or dig into.
  • As the engine of the snow blower accounts for most of the weight of the snow blower, and the drive wheels are typically situated directly beneath the engine, the drive wheels typically carry most of the weight of the snow blower. Accordingly, the glide wheels carry only a small portion of the weight of the snow blower, normally on the order of 250 newtons (mass of 25.5 kg) or less. The glide wheels may therefore be of moderate construction, and may be made of any appropriate material known to those skilled in the art. The glide wheels should be fairly narrow so as to displace as little snow as possible during snow blowing operations. In a preferred embodiment, the wheel width is about 2.5 cm. The wheels may be of steel or aluminum and have rubber or plastic running surfaces, or the wheels may be all-synthetic, providing the advantage of avoiding rust or corrosion, a feature that is of particular importance in the area of the bearings. The running surfaces are preferably abrasion resistant and relatively hard. In a preferred embodiment of the present invention, Polyolefin-cored wheels having polyurethane running surfaces without tread and Delrin® bearings are used.
  • The glide wheels are mounted generally parallel to each sidewall of the auger housing. In this embodiment, the glide wheels rotate during snow blowing operations along a substantially linear path. When sharp turns are encountered, such as corners, the glide wheels easily slide sideways to accommodate the turn. If desired, the glide wheels may articulate in the manner of a caster.
  • It is a further object of the present invention to provide a glide wheel mounting assembly means that is easily adjustable for the accommodation of a range of clearances between the scraper blade and the surface to be cleared of snow. In this embodiment, the glide wheel mounting assembly is comprised of a bracket plate to which a cylindrical axle for a wheel is perpendicularly affixed at a location in the central portion of the bracket plate. The area of the bracket plate where the axle is affixed may be raised by stamping, pressing or forging to provide a concave space, with room for a protrusion of the axle and means to bind the axle to the bracket plate, such as by welding. Viewed from the side, the bracket plate extends in width beyond the wheel, both to the left of the wheel and to the right of the wheel. In the portion of the bracket plate that extends past one side of the wheel, there is a hole to accept a bolt or other suitable fastener from the sidewall of the auger housing. In the portion of the bracket plate that extends past the other side of the wheel there is a slot to accept a bolt or other suitable fastener from the sidewall of the auger housing. The wheel is held onto the axle by a suitable fastening means such as a cotter pin, a stop nut, a cap nut, or other means that are known to those skilled in the art.
  • In yet another embodiment, there is one glide wheel mounting assembly for each of the two sidewalls of the auger housing. The assemblies are bolted into place on each sidewall of the auger housing. On each assembly, the side of the bracket plate having the hole acts as a pivot against which the bracket plate may be rotated. Such a configuration has the added advantage of vertical adjustment for the axle and wheel.
  • In yet another embodiment, the bracket plate could be slotted at both sides to accept bolts or other suitable fasteners, providing the additional benefit of increasing the range of the adjustment possibilities without extending the length of the slot.
  • These and other unique features of the glide wheel assembly and method disclosed herein will become more readily apparent from the following detailed description of preferred embodiments, the accompanying drawings and the appended claims.
