SNOW SCOOP Filed March 28, 1963 INVENTOR ATTORNEYS United States Patent M 3,218,738 SNOW SCOGP Raymond E. Bower-man, 2220 Avon, Saginaw, Mich. Filed Mar. 23, 1963, Ser. No. 268,699 2 Claims. (Cl. 37-53) The present invention is directed to a snow scoop and more particularly to a concave work faced structure useful for removal of ice and snow from the cave areas of house roofs without damage to shingles or roofing. Still more particularly, the invention is directed to a lightweight scoop having an elongate handle permitting the householder to remove snow burden from the cave areas of his roof without the necessity for using ladders, scaffolding, or the like during the winter months of snowfall, and wherein skids, extending from the scoop provide an avoidance of damage to roofing materials.

In northern climates, particularly, homeowners are aware of the damage to roofs brought about by the heavy snow burden at the unsupported overhang of the roof at the eaves. The damage is not restricted to the strain imposed by loading. The damage is also related to the building up of ice and snow so that, as the ice and snow melts and alternately freezes on the roof, it is forced upward and under the shingles, through the underlayment and sheathing and ultimately results in leaks and damp walls where the water is forced inside and upward by the alternate freezing and thawing condition. Homeowners have found that this condition is avoided if the cave area can be kept free of accumulated snow and ice. No tools for this purpose have been devised. As a result, shovels, and even garden rakes, have been put to use at great danger to the users and to the roofs since such implements occasionally rip or pierce the roofing material.

The present invention has, therefore, been devised to allow the homeowner to strip roof edge accumulations of ice and snow without damage to the roof and without ever leaving the ground.

Newer homes tend to have relatively shallow rather than steep roofs. This makes it more and more necessary to provide some simple means of snow removal.

Accordingly, the principal object of the present invention is to provide a unique concave faced snow and ice scoop for roofs.

Another object is to provide such a roof scoop wherein a handle extension is provided.

Still another object is to provide skid-like appendages to the working edge of such scoops so as to avoid damage to roofs and roofing material.

Other objects including rugged service construction will be more completely appreciated by those skilled in the art as the description proceeds.

General description In general, the invention comprises a blade element which is elongate and concave in curved planar form between the upper and lower edges. A socket is secured to the blade and extends from midway between the ends of the blade outwardly in the direction faced by the concave surface. The lowermost working edge of the blade is provided with skid-like projections which continue the concave surface but curve upwardly toward the concave surface of the blade thus spacing the working edge from surface contact where, for example, the scoop is drawn across a plane surface. The skid-like projections provide a spacing interval and their plane curvature allows the movement of the scoop over a roof surface without allowing corners or edges of the structure to dig into the roofing material.

The handle structure is of light weight and is selectively extendable as by the addition of handle sections using a 3,218,738 Patented Nov. 23, 1965 sleeve connector. This allows the homeowner to reach upward in accord with variant roof heights and the like and in avoidance of using ladders and the like.

In operation, the blade is extended upward by the operator and is then lowered into skid engagement with the roof. Then the blade is pulled by means of the operator in a downward motion toward the edge of the roof. The concave surface is thus moved toward the roof edge and entrapped snow and ice is thus scraped from the roof. The lower working edge of the blade is maintained in a parallel spaced relation above the roof plane surface by reason of the skid extensions and the skid extensions ride over the shingles or lapped roofing without gouging or damage. The homeowner then moves over and removes another strip of snow and ice from the roof edge.

Specific description Referring to the drawing and in particular reference to FIGURE 1, a scoop 11 attached to the handle 12 is shown extended upwardly by a homeowner or user 13 and onto the roof 14 of house 15 in the area of the eaves 16. It will be seen that as the scoop 11 is drawn downwardly along the plane of the roof 14, the skids 17 provide a guide so that the blade of the scoop 11 can at no time gouge the shingles 18 or roof 14. The skids 17 ride over the irregularities and maintain a smooth glide by reason of the curl and positioning of the skids 17. This action removes the snow and ice debris from a critical area adjacent the eaves 16 and prevents icing and water damage to the roof 14 and house 15.

In FIGURE 2 the preferred embodiment of the scoop 11 is shown. This comprises a blade 19 which is a gem erally rectangular piece of metal formed to provide a concave face 20 between an upper edge 21 and a lower working edge 22. A pair of skid-like projections 23 extend from the blade 19 in a generally tangential manner and then curve arcuately upwardly and rearwardly toward the concave face 29. The skid-like projections 23 are positioned at each end of the blade 19 and become the curved plane skids 17 seen in the schematic representation in FIGURE 1. A handle 12 is secured to the blade 19 so that the blade 19 is pulled toward the user 13 and snow and ice debris is scraped up by the working edge 22 and is gathered by the concave face 20.

The handle 12 is a lightweight elongate wood or metal tubular element which is insertable and secured in a socket 24 and is secured in place as by through fastener 25 or other suitable means such as by means of internal mating threads, rivets or the like as well known in the art of attaching handles in sockets. As will be seen later, the handle 12 is extendable in sectional increments to ad just for desired length.

The socket 24 is tubular to receive the handle 12 and is secured to blade 19 at the upper edge 21 thereof and midway between the ends of the blade 19. This attachment of socket 24 to the concave face 20 of the blade 19 is accomplished by welding, brazing, or by rivet fasteners 26, as shown. It will also be understood that the socket 24 may under certain circumstances be made integral with the blade 19 without departure from the spirit of the invention. The socket tongue portion 27 stiffens the blade 19 so that relatively thin light weight stock may be employed; the socket 24 is also provided with strap brace 28 diagonally in the plane of handle 12 and socket 24 which strengthens the connection of socket 24 to blade 20 in elimination of fatigue between socket 24 and blade 20. This ideally adapts the scoop 11 to the contemplated pulling action on the handle 12.

In FIGURE 3 a modified blade 19' is shown in which a recurled skid 23 is employed. The recurled skid 23' is made integral with the blade 19' and extends tangentially therefrom at the ends of the working face 22' and then spirals outward and upward to substantially close on the concave surface 20'. The tangential extension is sufficient to space the Working face 22 from contact with a plane surface over which the blade 19' is drawn.

FIGURE 4 represents another modification of skid to blade. The skid 23" on blade 19" comprises a split tube slipped over the blade 19" at the ends of the working face 22" and secured thereto as by welding or brazing. The wall thickness of the tubular skid 23" provides the desired spacing interval in use between the surface worked on and the working edge 22". Where spacing is desired to be greater than the wall thickness of the tubular skid 23", then attachment of the tubular skid 23" to the blade 19" is selected to provide the desired offset from the working edge 22". Theselection of. diameter for the tubular skid 23" is made in accord with the skid action desired and approximates the action obtained by the

skids

23 and 23. The advantage is a matter of cost since less scrap is involved with the non-integral skid 23".

In FIGURE still another modification of the invention is shown wherein a non-integral skid 23 is secured to the blade 19 at each end of the working edge 22" as by welding, brazing or riveting to the blade 19". The form of the curl is either as in FIGURE 1 or FIGURE 3 and again some cost advantage is obtainable by reason of a stock saving unobtainable if the skid were formed integrally with the blade. Substantially equal performance is achieved using the skid 23" and the working edge of the blade 22 is seen to be more rigidv in the FIGURE 5 form of structure.

In FIGURE 6 the handle 12 is shown extended by addition of extension handle increment 29 as secured together by coupler 30. The handle extension 29 is made from wood or tubular metal stock. The coupler 30 comprises a tubular section of an internal diameter to provide a slip fit over the diameter of handle 12 and increment 29. The coupler 30 is pierced diametrally to accommodate

screws

31 and,32 which pass through

openings

33 and 34 in register with the pierced openings in the coupler 30. Wing nuts 35 and 36 respectively serve to threadably engage the, screws 31 and 32 to secure the handle 12 and handle increment 29 in parallel axial alignment and against the pulling action imparted through the handle and to the scoop 11.

Operation In operation, the scoop of the present invention is assembled to suitable length by adding selected handle increments. This allows the scoop to be extended from the ground and onto the roof adjacent the eaves. By pulling the scoop toward the eaves the snow and ice debris is scooped off of the roof edge. During this action, the skid members ride over roof irregularities and space the lower working edge of the scoop blade from damaging contact with the roof or roofing materials. Seasonal usage of the scoop of the present invention has resulted in avoidance of roof damage at the eaves which is so prevalent in newer homes with shallow roof overhang.

Having thus described my invention, additional changes, modifications, and improvements will be appreciated by those skilled in the art and such changes, modifications and improvements are intended to be included as they fall within the scope and spirit of the hereinafter appended claims.
