April 15, 1952 c. A. HANSON ET AL 2,593,025
SNOWPLOW SHOE Filed April 1, 1947 w m5 0N A N EH A m s E L .R A H C ALBERT L. HANSON ATTORNEY Patented Apr. 15, 1952 ""Munisiirgg Mi Application April 1, 194*I-; sii' 1 Claim. (c1 8 The object of our invention is to provide novel snow plow shoes made in one piece instead of being made in two parts bolted together as has been the usual practice. Where the snow plow shoe is made in two parts and bolted together, there is danger of the shoe breaking through the bolt holes before the shoe is completely worn out from use.
It is also an object of our invention to pro- .vide forms which lendthemselves to chill casting whereby longer wear is obtained from the shoes.
It is also an object of our invention to make a snow plow shoe which is easily installed and which will last much longer than the snow plow shoes heretofore in use.
We attain these and-other objects of our invention by the mechanism shown in the ac vention having an upstanding central portion integral with the rest of the shoe.
Fig. 6 is a modification of the form shown in Fig. 5 in which the upstanding central portion is narrower than in the form shown in Fig .5; and I Fig. 7 is a modification of the form shown in Fig. 1 in which the ends are not as curved and an additional reinforcing strip of steel is included.
Referring to the drawings and specifically to Fig. 1, I provide a shoe I having opposite upwardly curved ends 2, a longitudinal reinforcing rib 3 and a. central upstanding projection 4 through which a bolt hole 5 extends transversely.
Referring toFig. 2, I provide a pair of spaced elongated upstanding projections 6 which extend substantially the length of the shoe and through which bolt holes I extend transversely,
as shown.
Referring to Fig. 3, there is illustrated a modification of the invention having shorter upstanding projections 8 through which bolt holes Referring to Fig. 4, there is illustrated another modification of the invention having upstanding projections Ill spaced farther apart and adjacent the edges or the snow plow shoe and having oprt 13h- M M pxtending transversely through said projections Ill.
Referring to Fig. 5, there is illustrated another preferred modification of the invention in which a single upstanding projection I2 is provided which extends the entire width of the snow plow shoe and through which transversely extends the bolt'hole I3.
Referring to Fig. 6, there is illustrated a modification of the form shown in Fig. 5 in which a narrower projection I4 is provided and the end of the shoe issomewhat differently shaped.
Referring to Fig. 7, there is illustrated a modification of the form shown in Fig. 1 with a longitudinal reinforcing rib 3 and an inverted approximately U-shaped strip of steel I 5 cast in the metal of the projection l6 where there-is not clearance enough between the shoe and the snow plow for enough cast-iron to hold the shoe without the bolt breaking off the top of the projection.
The snow plow shoe is connected to the snow plow by a suitable snow plow hitch to which it is engaged by a bolt extending through the bolt holes shown in the drawings. These snow plow shoes slide the plow along the ground, thereby wearing out the replaceable shoes or skids rather than wearing out the plow proper. The larger plows have three shoes under them, one under each wing and one in the point of the plow. The smaller plows have two shoes, one located under each end. All the shoes are of the same basic design, namely, having one bolt to attach them to the plow and all having one or more upstanding members or longitudinal projectionswith the bolt hole through said upstanding members. This invention eliminates putting the bolt holes through the bottom of the shoe which would tend to weaken the shoe. The zhoe is easily installed on the plow with a. single olt. All the forms shown lend themselves to chill casting where the bottom part of the shoe becomes very hard to the point of brittleness while the projection through which the bolt passes remains reasonably soft and tough, thereby serving as a strong back to prevent the bottom half of the shoe from breaking. This fact alone will enable the shoe to wear from three to four times longer than the ordinary cast-iron shoe.
In Figs. 5, 6 and 7, the ends of the shoes do not turn up as much as the shoes shown in the other figures. This is because on some plows there may be an obstruction that the end of the 3 shoe strikes against in oscillating on the bolt if the ends of the shoe are built up too high. All models of our shoes can be made with or without this feature.
We claim:
A snow plow shoe having upwardly curved opposite end portions and spaced integral upstanding projections on its top surface extending substantially the length thereof and providing longitudinal reinforcement therefor, said projections being provided with opposed apere tures for attaching the shoe by a single connecting bolt, the bottom portion of said shoe being provided with a relatively hard brittle wear-resistant surface with the upper portion of the shoe relatively soft and tough and strengthening the relatively hard brittle bottom portion against breakage, whereby increased REFERENCES CITED The following references are of record in the file of this patent:
