SNOW/PLOW.

SPECIFICATION forming part of Letters Patent No. 399,895, dated March 19, 1889.

Application filed March 29, 1888.

To all whom it may concern:

Be it known that 1, ERIC M. l'IEssELBoM, of Rushford, in the county of Fillmore and State of Minnesota, have invented a new and Improved Snow-Plow, of which the following is a full, clear, and exact description.

The invention relates to a snow-plow for which Letters Patent No. 263,1 78 of the United States were granted to me under date of August 22, 1882.

The object of the invention is to provide a new and improved snowplow which is very simple and durable in construction and very effectively cuts up the snow and discharges it the wings E and E, respectively.

dicate corresponding parts in all the figures. Figure l is a side elevation of the improve- Fig. 2 is a plan view of the same, and

; end of the truck B.

B, of any approved construction,and adapted to be pushed forward by a locomotive or other inotive power. The snow-plo'wA is provided with a bottom, C, extending rearwardly and upwardly, and having at its front end a cutting-edge, C, reaching to within a short distance of the track-rails on which the truck 3 runs. The front edge, projects a suitable distance in front of the truck I In the middle of the bottom C and a short distance from its cutting-edge is erected a knife or cutter, D, having an inclined front cuttingedge, D', and extending rearwardly, terminatingin the sidewisc and rearwardly-extend-v ing curved wings E and E.

At each side of the bottom (1 and near its I sides II.

tral knife or cutter, D, and secured to the same by suitable means.

The rear edges, F, of the side knives, F, are nearly perpendicular and preferably slightly curved, as shown in Fig. 1. From the rear end of each knife F extends rearwardly a wedge-shaped side plate, H, terminating in a point at its rear end near the bottom edges of The plates H are secured to the side edges of the bottom 0, thus forming, with the central knife or cutter D, a chute or passage-way for the snow. On the top edge of eachwingE or E is hinged an upwardly-extending wing, I or I, respectively, serving to prevent the snow from passing over the top edges of the wings E and E and onto the truck B or between the trackrails.

The rear ends of the extension-wings I and l are connected with each other by a brace, J, which can be removed, so as to permit the wings I and I to fold inwardly when the snowplow is not in use.

The operationis as follows: The snow-plow A is driven into the snow-bank by a locomotive or other motor pushing against the rear The front cutting-edge, O of the bottom C cuts into the snow and causes the latter to pass onto the top of the bottom C. The side knives, F, and the central knife, 1) also cut into the snow-bank to its full depth, so that two blocks of snow are cut out of the bank, and the said two blocks pass rearwardly along the bottom 0 on the forward movement of the plow in the chute formed between the central, knife, D, and the *hen the two blocks of snow finally come in contact with the wings E and E, respectively, they are forced outward and over the top edge of the side H near their rear ends.

The snowis thus delivered a suitable distance 1 easily and rapidly cleared from snow.

front end is held a knife or cutter, F, which extends upward and outward, having afront cutting-edge, F, slightly inclined rearward, as shown in Figs. land 2, and extending from f to f in line with the edge D of the central knife, D. The top edges of the two side knives, F, are connected with each other by a brace,

' Patent In a snow-plow, the combination, with an G, also passing over the top edge of the cenl inclined bottom, of a central vertical knife held on the said bottom, Wings extending rearwardly from the rear end of the said central knife, extension-Wings hinged to the top edges of the said Wings, side knives secured to the sides of the said bottom near its front end,

the said side knives extending upward and outward, a brace secured to the top edges of the said side knives and central knife, and

Wedge-shaped sides extending rearward from the said side knives and along the sides of the 10 said bottom, substantially as shown and described.
