SNOW SHOVEL Filed Oct. 4, 1961 l lm United States Patent 3,082,554 SNOW SHOVEL Karl Steeb, 149 Harlem Ave., Buffalo, N.Y. Filed Oct. 4, 1961, Ser. No. 142,841 2 Claims. (Cl. 37-123) This invention relates to a snow shovel and more particularly to such a snow shovel which permits of the removal of all types of snow, that is, heavy and light, fresh and partly refrozen, with less efiort and fatigue than conventional shovels.

It is an important object of the invention to provide a lever and fulcrum action which, on depressing the rigid handle of the shovel will lift the entire scoop thereby to break all sides of a body of snow on the shovel from the snow bank.

It is another important object of the present invention to provide a snow shovel which embodies both such a lever and fulcrum action for initially raising the shovelful of snow from the ground and also a swinging handle arrangement for subsequently lifting and swinging the snow shovelful with a minimum of stooping or other exertion beyond relative movement of the arms of the shoveler.

Another object of the invention is to provide such a snow shovel in which the shovelful of snow does not interfere with the movement of any of the working parts and in particular in which none of the moving parts have to work through the shovelful of snow in the shoveling operation.

Another important object of the invention is to provide such a shovel which is securely held at three widely spaced points so that the shovel automatically levels itself to avoid both accidental discharge of a shovelful of snow and also to avoid the necessity of any effort to hold the shovel level.

Another object of the invention is to provide such a shovel which spaces itself at proper elevation from the ground to facilitate entry of the scoop into the snow bank, this being achieved by runners Which also form part of the fulcrum structure.

Another object of the invention is to provide such a shovel in which its runners can also be used like a sled in moving the shovel from place to place.

A further object of the invention is to provide such a snow shovel which is shaped to cut the snow away in the form of a large block each time the shovel is used, this being achieved by high thin side walls for the scoop in combination with the lever and fulcrum action which lifts the entire scoop.

Another object is to provide such a shovel which is of light weight skeleton form but at the same time is adequately reinforced to be rugged and to stand up under conditions of severe and constant use without getting out of order or requiring repairs.

Other objects and advantages will appear from the following description and drawings in which:

FIG. 1 is a side elevational view of a snow shovel embodying my invention and showing the same in position to enter the bank of snow along the ground.

FIG. 2 is a top plan view thereof.

FIG. 3 is a transverse section on an enlarged scale taken generally on line 33, FIG. 1.

FIG. 4 is a vertical longitudinal section, on an enlarged scale, taken on line 44, FIG. 2.

In the accompanying drawings the parts of the snow "ice shovel are shown in the position which they would occupy in the hands of the user preparatory to entering the bank of snow along the ground.

The scoop of the snow shovel is indicated generally at 10 and is in the form of a rectangular piece of sheet metal having two side walls 11, the scoop being curved to forma bottom wall 13 and a reversely curved rear wall 14, the leading edge 15 of the scoop forming the horizontal bottom cutting edge of the shovel which is moved horizontally along close to the ground to out under and elevate a shovelful of snow onto the bottom 13. To facilitate such movement and to avoid digging in of the forward edge 15 into the ground or gravel or upwardly projecting concrete pieces or other low obstacles which may comprise the surface being shoveled each side wall 11 is provided with a horizontal bottom runner 18 which extends horizontally rearwardly from the cutting edge in the position of the shovel preparatory to entering the bank of snow along the ground and each runner in this position preferably extends rearwardly beyond the rearmost extremity of the scoop 10 as best illustrated in FIG. 4. The rear of each runner 18 is formed to provide a socket 19 having a horizontal bore 20, the bores of the two side walls being in axial alinement with each other and each containing the end of a cross rod 21 which is preferably made of wood and of cylindrical form. This cross rod can be secured in position as by screws 22 extending through the walls of the sockets 19 and anchor ing in the ends of the cross rod 21 as best shown in FIG. 3.

Each side Wall 11 also includes a generally vertical bar 25 extending upwardly from the socket 19 and at its upper end curving forwardly to terminate at the upper horizontal edge 26 of the rear wall 14 of the scoop 10. From this point each side wall is continued downwardly in the form of a curved bar 28 which conforms to the shape of the sheet metal scoop 10 and joins the forward end of the runner 18, the edges of the sheet metal scoop 10 being secured to one face of this curving bar 28, as by welding. Each of these curving bars 28 is in the form of a curved flange extending inwardly from an imperforate side wall 30 which side walls form the vertical sides above the scoop and the upper edges 32 of which form cutting edges which separate the sides of the shovelful of snow being removed from the bank both to facilitate removal of the shovelful of snow and also to insure shoveling a path having vertical sides.

Each entire side wall 11 can be made in the form of a single stamping and it Will be noted that it is provided with a large opening 35 in the rear of the scoop 10 thereby to reduce both the weight and the cost of the shovel.

A feature of the invention resides in the provision of a bail-like handle indicated generally at 40 in addition to the more or less conventional stifi or rigid handle indicated generally at 41. The rigid handle can be in the form of a wooden shaft 42 having its lower end inserted into a sheet metal socket 44 secured, as by welding, to the rear face of the scoop 10 intermediate its bottom wall 13 and rear wall 14. At this point the shovel can be reinforced by a sheet metal strut 45 which is shown as being of square tubular form in cross section with its upper end secured as by welding to the socket 44 and its lower end bearing against the center part of the wooden cross bar 21. The outer end of the stilf handle 41 is shown as having a conventional handle grip 46.

The bail-like handle 40 preferably includes a somewhat stiff length of wire or cable 50 the opposite ends of which are secured in anchor fittings 51 which later are secured to the rear face of the rear wall 14 at the opposite extremity thereof so as to be widely spaced from the center of the shovel. A tubular grip 53, preferably made of wood, surrounds the center part of the stiff cable 50 and can be secured in position in any suitable manner (not shown), the sides Slla of the cable diverging from the ends of the grip 53 to the anchorages 51. When not in use the grip 53 can be attached to the stiff handle 41 in any suitable manner as shown by dotted lines in. FIGS. 1 and 2, the shaft 42 being provided for this purpose with a catch, shown as being in the form of an eye 54- by which the grip 53 is caught. It will be noted from an inspection of FIG. 1 that with the runners 18 of the scoop riding horizontally on the ground and the bail like handle 41 raised to an upright position, the grip 53 of this handle is at approximately the same height as the grip 46 of the rigid handle 4-1.

In the use of the .snow shovel the operator moves the rigid handle 41 so as to cause the cutting edge of the scoop 10 to cut down into the snow bank (not shown) until the runners 18 are brought into engagement with the surface of the groundthe full length thereof. The shoveler then releases the grip 53 of the bail-like handle 4!) from the catch 54 and seizes this grip 53 with one hand and the grip 46 with the other hand. By a hori zontal pressure applied to the grip 46 of the rigid handle 11 he then causes the scoop 10 to move forwardly with its runners 18 travelling along the surface of the ground so as to cause the cutting edge 15 to travel under the shovelful of snow to be removed and so as tocause this shovelful to be piled up on the scoop. In this movement the top edges 32 of the side walls 11 of the scoop cut the sides of the shovelful of snow being removed so as to produce vertical side walls in the shoveled path. This function of the vertical side walls 11 is particularly advantageous when shoveling through deep snow.

After a full load of snow has been gathered on the shovel, the shoveler presses downwardly on the grip 46 of his rigid handle 41. This causes. the sockets 19 to be brought into pressure contact with the ground and to act as a fulcrum in lifting the entire scoop 10. In this lifting or upward movement of the scoop 10 the upper edges 32 of the side walls 11 of the scoop cut upwardly through the body of snow to be removed thereby to further separate this body from the surrounding bank. Also the forward cutting edge 15 is moved upwardly so as to cut the forward end of the shovelful of snow being removed from the bank. The net efiect, of this upward movement of the scoop 10, particularly with heavy or somewhat packed snow is to separate a complete block of snow from the bank as the shovelful to be removed.

Accordingly, the loadedshovelful can now be moved rearwardly preparatory to the final swing and in this rearward movement the grip 53 of the bail-like handle is lifted slightly so as to free the fulcrum engagement of the sockets 19 from the ground and the grip 46 of the stiff handel 41 is moved .rearwardly.

At the end of the rearwardswing the shoveler moves the grip 46 of the stiff handle 41 forwardly and at the same time progressively lifts the grip 53 of the bail-like handle 40 so that the movement of the shovel ful of snow is upwardly and forward, taking full advantage of the return pendulum action of the load from its rearward swing. In this forward movement the scoop is guided to swing to one side and in this movement it will par ticularly be noted that the shoveler has full control of the movement of the shovel from three widely spaced points, namely the grip 46 of the stiff handle 41 and the widely spaced anchor fittings 51 for the bail-like handle 40'. At the end of the swing the shovel is brought to a stop but the shovelful of snow continues sliding off the scoop 10 to the side of the path being shoveled.

It will be noted that by virtue of the long rigid handle 41 in relation to the fulcrum provided by the sockets 19 a very powerful leverage advantage is provided in lifting up the entire scoop 10 to carve out a shovelful of snow from the bank, this being accomplished with little effort and being particularly effective where the snow is heavy and packed or partly refrozen. At the same time by locating these fulcrum points 19 behind the scoop 10' the entire scoop is lifted so that the full length of the cutting edges 32 provided by the side walls 11 is effective in cutting through the body of snow to be removed as a shovelful and also the horizontal cutting edge 15 of the scoop is lifted a very substantial distance so as to cut away the front part of the shovelful of snow from the bank. It will also be noted that by the wide spacing of the anchor fittings 51 the scoop is supported from three widely spaced points and under full control at all times. It will also be noted that by securing the anchor fittings 51 to the rear face of the rear wall 14 of the scoop, the bail-like handle 4% never comes in contact with the shovelful of snow and does not interfere with its free release at the end of the discharge swing of the shovel. It will also be noted that the rails 13 are effective in holding the cutting edge 15 of the scoop at the proper elevation and to avoid this cutting edge digging into the ground obstacles and that also the rear ends of these rails, as well as the fulcrum points provided by the sockets 19 are adequately strengthened and also acts as a reinforcement by virtue of the strut 45 between the center of this rod and the socket 44 for the rigid handle 4-1.

Also each side wall 11 can be made of low cost sheet metal and :by virtue of the large opening 35 therein behind the piece 12 of sheet metal, it can be made light in weight and lower in cost. Also, by virtue of the runners 18 the shovel can be moved from place to place with little effort.
