Snow stop includes a base member, and a snow-restraining member. The snow stop can have a series of holes for ventilation of adhesive as well as for forming "glue-rivets" with cured adhesive, and can have slots (grooves) to the holes or boundary of the snow stop to assist in ventilating adhesive solvent. The holes and grooves also can provide for increased physical bonding with the adhesive and hence, roof. The base may be round with the snow-restrainer included in intersecting upstanding member...

Apparatus is disclosed for removing snow from an inclined surface such as a structural roof, including an elongated flexible sheet having a low surface coefficient of friction, and adapted for sliding along the inclined surface, the sheet being attached to a rod and the rod having an attachment for propelling the apparatus.

A snow skate is disclosed which provides improved control and skate-like performance, particularly on hard-pack or icy surfaces. The snow skate has edges which increasingly project from the central flat region of the ski to the forward area. Preferably this is achieved by making the base increasingly concave forward and rearward from a central generally flat region.

A snow plow with a clutch mechanism for allowing the plow blade to deflect when an off-center portion the blade strikes an obstacle.The clutch comprises two plates in axial alignment, with one plate being attached to brackets for the plow support and the other plate being attached to brackets supporting the blade. One plate has a number of small protuberances and the other plate a corresponding number of shallow pockets. The plates are releasably held in nested relation by an axially adjustable ...

In a snow gun, each of air and water are discharged through V-jet nozzles in the form of generally flat and V-shaped jets or sprays. The nozzles are spacially positioned and angled so that the air jet intersects the water spray along a line of intersection where they are of equal width. This provides efficient atomization of the water with the result that snow can be made at milder freezing temperature.

A surfboard for surfing on snow has an hourglass profile including dimension lines curved inwardly in the runner zone, and wherein bindings each form an angle with a line perpendicular to the longitudinal axis of the surfboard. Both dimension lines are offset longitudinally with respect to each other and are positioned so that the most curved point of each dimension line is located on the axis of symmetry of the axes passing through the two bindings.

A snow blower augers snow scrapped from a path to a fan. The fan is co-axial with the auger at one end of an auger housing. A fan shaft extends through an auger tube. The fan shaft is supported on one end by a fan housing bearing attached to the housing and at the other end by a bearing in the auger tube. The auger is supported at one end by a drive housing bearing attached to the housing and at the other end by a bearing on the fan shaft. This arrangement makes it possible to have an open passa...

A method and an apparatus for producing ridges on snow covered fields are described. A row of snow is severed from the snow cover and elevated to provide a trench in the snow cover. The row is then deflected to one side of the trench and deposited on the undisturbed snow covering beside the trench. This produces a wind barrier on the snow covered field, reducing wind erosion of the snow cover. In preferred embodiments, two spaced trenches are cut and the rows of snow removed from them are placed...

A snow vehicle having a frame, a body, a windscreen on the frame, two front steerable skis and two rear crawler tracks. An engine and drive train are located at the rear for driving both of the tracks. The drive train includes two fluid couplings, each coupling a crawler track, respectively. Two seats are positioned forwardly of the engine at the intersection of two lines seen in plan to extend from the geometric centers of front skis to the geometric center of opposite rear crawler tracks. A st...

A snow brake has three major portions, all of which are formed together in a single mold by casting. The first part is a gripper base having a rectangular U-shaped cross-section and an elongated side elevation. A slit extends upward from a bottom of the base to receive a roof seam. Set screw openings extend inward from one side wall and to the slit. Indentations are formed in the side opposite the set screw openings, so that the set screws may press portions of the seam into pockets formed by th...
