SNOW PUSHER.

Application filed December 1, 1923.

To all whom it may concern:

Be it known that I, SAMUEL A. Brown, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in Snow Pushers, of which the following is a specification.

My invention relates to snow pushers and its objects are to provide a snow pusher.

which will require comparatively little offort by its user to push snow, which when pushed against a layer of snow will cause it to roll; which will retain its sharp edge and proper adjustment as it wears; which is so balanced that strainsproduced will be transmitted equally to all parts, and which is of simple and rugged construction.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a picture view illustrating my improved snow pusher in. action rolling up a layer of snow,

Figure 2 a front face view of Figure 1,

Figure 3 an enlarged fragmentary rear view of Figure 1,

Figure 4 a section on line 4-4 of Figure 3, and

Figure 5 a diagrammatic view of the cross section of a blade which forms a part of my invention.

Referring to the drawings 1 indicates a blade having a curved part 2 preferably arcuate in cross section, a flat part 3 integral with the lower edge 4 of the curved part, and a fiat part 5 integral with the upper edge 6 of the curved part. The flat part 3 is disposed within an are 7 coinciding with the arcuate part 2 and the flat part 5 is disposed without the are as shown in Figure 5. The flat part 3 will retain its sharp edge and angular relation to the pavement until it is worn out, thereby insuring an efiicient wedging action for separating snow or ice from a pavement at all times.

The pushing means includes a socket 8 preferably provided with openings 9 for lightness and having integral arms 10 diverging from the socket. The closed end 11 of the socket abuts curved part 2 adjacent its upper edge 6 and arms 10 extend Serial No. 677,940.

end 11 of the socket, stiffen the connectionbetween the socket and the arms. A handle 14- fits within socket 8 and is secured thereto by screws 15. It IS readily seen that these parts, which constitute the pushing means, are designed and positioned to transmit all strains from the blade to the handle and thus prevent distortion of the blade.

To use my improved snow pusher the flat part 3 is forced through the snow to the pavement. This brings the blade 1 in position to push the snow and cause it to roll. By pushing on handle 14:, flat part will separate the layer of snow or ice from. the pavement; the curved part 2 will cause the layer to turn over on itself, and flat part 5 will prevent the layer from fall-- ing rearward without forcing the snow into a hard roll which would make it difficult to push the blade against the snow. Thus by pushing handle 14 the parts 2, 3 and 5 all function to cause the layer of snow to roll so that comparatively little effort is required by the user to clean snow off the pavement. In case flat part 8 should enan obstruction in the pavement which would abruptly stop its movementand produce a torsional strain on the blade, the arms 10, socket end 11 and ribs 13 will transmit this strain to handle 14 and thereby prevent distortion of the blade.

By constructing a snow pusher with a blade having a flat part on the opposite edges of a curved part, the snow or ice may be easily cleaned oif the pavement by merely pushing the blade. By providing a socket having its end abutting the blade adjacent the upper edge and the arms extending to a point adjacent the lower edge, the snow pusher may be used on a pavement having an uneven surface without distorting or bending the blade.

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is I 1. A snow pusher provided with a blade having a curved part, and a flat part extending from the upper edge of the curved part.

2. A snow pusher provided with a blade having an arcuate part and a flat part extending from the upper edge of, the arcuate part, the fiat part being without an arc coinaiding with the arcuate part.

3. A snow pusher provided with a blade having a curved part; a flat part on the lower edge of the curved part,v and aflat part on the upper edge of the curved part.

4. A snow pusher provided with a blade having an arcuate part; a flat part on the lower edge of the arcuate part, and a fiat part on the upper edge of the arcuate part,

the flat part on the lower edge being within an arc coinciding with-the arcuate partand the flat part on the upper edge being without the arc. I

5. A snow pusher including a blade having a curved part; a socket having its closed end abutting the curved part adjacent its upper edge; arms diverging from the s0cl et, secured to the curved part and extend ing to the lower edge thereof, and a handle in the socket.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
