A snowplow mount is provided wherein a vehicle mount extending from the plowing vehicle is affixed to a reversing table, which is in turn rotatably connected to a plow moldboard at one or more pivots. One of the moldboard or the reversing table includes a bearing thereon, the bearing having a bearing bore defined therein. The other of the moldboard or the reversing table includes a pin which is elastically journalled within the bearing so that the pin and bearing may both rotate with respect to each other as well as translate with respect to each other in radial directions (i.e., in planes which are generally parallel to the axes of the pin and the bearing bore). Thus, loading of the moldboard allows the moldboard to translate with respect to the reversing table at the pivot as well as rotate. The reversing table is rotatably affixed to the vehicle mount with a linear actuator affixed therebetween so that actuation of the linear actuator will cause the reversing table to rotate with respect to the vehicle mount. The linear actuator is elastically mounted between the reversing table and vehicle mount so that the two may rotate a slight amount with respect to each other, with such rotation being elastically resisted. As a result, shock loading of the moldboard (and thus the reversing table) will not be readily transmitted to the linear actuator.

A combined shovel and clearing tool with a shovel and a clearing tool member for being coupled to the shovel. The clearing tool member can be selectively retained in a usage disposition, such as relative to a leading edge of a shovel blade, and in a storage disposition, such as relative to a trailing edge of the shovel blade or relative to a handle of the shovel. The clearing tool member can be retained by, for example, a clip arrangement, an elastic tether, or a rigid arm. Bristles can project from an obverse side of the shovel blade. The handle and the blade can be reconfigurable by, for example, a relative pivoting or a selective coupling of the handle with multiple receiving portions on the blade. A universal clearing tool can be coupled to a standard shovel.

An automotive vehicle safety device for melting ice and snow on roadways and in areas immediately adjacent the vehicle tires includes ductwork extending from a heater mounted adjacent the vehicle engine with the ductwork terminating at front and rear undercarriage mounted v-shaped ducts. Each v-shaped duct includes a pair of heating vents disposed adjacent each vehicle tire that blows heated air onto the roadway for melting the ice and snow. A heating grid is securable to the vehicle undercarriage for providing additional radiant heat to melt ice and snow, and a dashboard-mounted control panel provides for the manual activation of the heater and the heating grid while sensors mounted to the undercarriage and electrically connected to the control panel provide for automatic activation of the heater and heating grid upon sensing a predetermined temperature.

A vehicle is disclosed which includes a chassis and a storage and dispensing apparatus. The storage and dispensing apparatus can be mounted directly to the chassis or disposed within or on a body, which in turn is mounted to the chassis. The storage and dispensing apparatus has an opening therein to permit material to be transported therethrough. A conveyor assembly for selectively conveying materials from the opening of the storage and dispensing apparatus is also included. The conveyor assembly can include a dual auger arrangement. The vehicle includes a spreader chute that is operably arranged with the conveyor assembly to direct the materials to a spreader. A liquid storage system for storing liquid is provided. A liquid dispensing system is provided for selectively dispensing liquid from the liquid storage system. The liquid dispensing system includes an anti-icing system for selectively dispensing liquid from the vehicle and a pre-wetting system for selectively dispensing liquid onto material being transported by the endless conveyor out of the vehicle.

The snow shovel easily and with minimal effort, scoops up a pile of snow, pivot and wheels the contents to another location, whereupon operation of a lever releases its load. The telescoping frame and rotatable handle provides a selection of lockable positions. The front mounted scoop head is pivotally mounted to the lower end of the frame. Upon activation of a release lever, the scoop head is allowed to rotate downward, releasing its load. A wheel assembly mounted to an intermediate portion of the frame supports the shovel in an inclined position, allowing the user to concentrate on applying force in a forward direction rather than expending effort lifting the handle. Furthermore, the wheel assembly acts as a fulcrum whereby downward pressure on the handlebars of the shovel elevates the scoop for ease of transport. The wheel assembly may be rotated towards the frame when not in use.

A single joystick type control handle controls the chute and deflector of a snowthrower. The control handle can be moved laterally from side to side and a second linkage including a gear connection laterally rotates the chute from side to side in the same direction, i.e. movement of the control handle to the left rotates the chute to the left and vise versa. The gear connection has a mechanical advantage that increases the amount of the angular rotation of the chute, i.e. the chute rotates further than the angular movement of the control handle. The control handle can also be moved longitudinally from fore to aft and a second linkage comprising a flexible cable pivots the deflector up and down on the chute in the same direction, i.e. moving the control handle forward pivots the deflector down and vise versa. A locking mechanism is provided to hold the chute and the deflector in their adjusted positions.

This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15). We protect homeowners, their cars and their plows from injury when plows strike hidden objects. Protection devices comprise safety springs (60) and pivots (63, 67 and 69) of FIG. 3B, the tension-release mechanism mentioned but not detailed in FIG. 15, annor shields (396, 398) of FIG. 16 and various others mentioned or provided for in our drawings but not detailed. We prefer cars' chassis tie-down ears (72) in FIG. 3A, as connector points for our plow or thrower arms. For cars lacking such ears, we propose add-on ears. For example, tie-down ear (126) in FIG. 6.
