RAILROAD SNOW-PLOW AND CAR COMBINED.

SPECIFICATION forming part of Letters Patent No. 376,698; dated-Tanuary 17, 1888.

' L Application filed October 30, 1886. Serial No. 217,628. (No model.)

To aZZ whom it may concern:

Be it known that I, JosEPH WooLLEY, a citizen of the United States, residing at Rutland, in the county of Rutland and State of Vermont, have invented a new and useful Snow- Plow and Car Combined for Removing Snow from Railroads, of which the following is a specification.

My invention relates to an improvement in that class of railroad snow-plows in which are combined rearwardly and upwardly inclined surfaces of a different degree of inclination, mold-boards, and cutters upon said surfaces.

The objectof my invention is to provide a snow-plow which shall require less power to successfully operate the same, and which shall at the same time do its work more effectually than the devices of this class heretofore in use; and with these ends in view my invention 0011- sists in the'combination,with a forward wedgeshaped inclination, inclined surfaces continuing upwardly and rearwardly from the-forward inclineat a less degree of inclination than the same, and downwardly-extending sides, of the mold-boards provided with a beveled point or cuttingedge and extending from the center of the upper port-ion of the forward incline to the rear corners of the plow with agradual increasinglateral curvature, the outline ofsaid mold-boards from their point to their rear ends being vertically concave in cross-section, cutters upon theopposite edges of the first incline and extending-rearwardly to and upon the rear inclines, the side faces of said cutters tapering upwardly-from their lower portions and their front edges sloping upwardly and rearwardly and being beveled to form a sharp cuttingedge, and a top covering the upper portions of said mold-boards and projecting beyond the edges of the same.

In the accompanying drawings, Figure 1 is a side elevation of my complete device; Fig. 2, a top plan view of the same; Fig. 3, an'end elevation, and Fig. 4 a front elevation.

In the drawings, the reference-letter E indicates the sidesof'a car carrying and forming a part of my improved snow-plow. The forward portion of the plow consists of a wedgeshaped nose or projection, D, provided with an upwardly andrearwardly sloping upper surface, WlllChl'EflOllGS its highest point at the line a a, which line also marksthe lowest point of surfaces P P, sloping upwardly and rearwardly to the end of the car, but at a less de gree of inclination than the slope of the first inclination, D. Y Vertical mold-boards B B are located upon said inclines P P and D, the beveled point a ofsaid mold-boards being centrally. located upon the upper part of the first incline, D,

from which point the mold-boards extend to the rear end corners of the car with a gradual increasing lateral curvature, and the vertical out-line of said mold-boards in cross-section is vertically concave from the point it to the rear end of the mold-boards, as shown in Figs. 3 I

and 4; but I wish it understood that the moldboards do not change their vertical position and form a spiral curve, as has heretofore been the case.

Beveled cutters G O are located upon the,

opposite edges of the first incline, D, and extend rearwardly asho'rt distance upon the upper inclines, P P. The side faces of these cutters O G gradually taper upward to their top edges, and their cutting or front edges, 0', slope, upwardly and rearwardly and are beveled to form a sharp cuttingedge, 0'.

being removed in its passage up the inclines, and by constructing the cutters in the above- The cutters limit the width of the cut and guide the snow 7 described form they offer the least resistance 1 possible to the passage of the snow.

A horizontal top or roof, A, is secured upon the upper edges of said mold-boards, and the outer edges of the top are madeto conform to the lateral curvature of the mold-boards and project a short distance'beyond the edges of the same. p

By constructing the mold-boards, inclines, and cutters in the manner before described, a snow-plow is produced which, when performing its work, imparts to the snow being removed a gradual upward and lateral motion in such a mannerthat the resistance offered to the passage of the snow and the forward movement of the plow is reduced to a minimum.

Having fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isv 1. In asnow-plow, the combination ofa forward wedgeshaped incline, inclined surfaces wardly from the forward incline at a less degree of inclination than the same, and the downwardly extending sides, of the moldboards provided with a beveled point or cutting-edge and extending from the center of the upper portion of the forward incline to the rear corners of the plow with a gradual. increasing lateral curvature, the outline of said mold'boards from their point to their rear ends being vertically concave in cross-section, cutters upon the opposite edges of the first incline and extending rearwardly to and upon the rear inclines, the side faces of said cutters tapering upwardly from their lower portions and their front edges sloping upwardly and rearwardly and being beveled to form a sharp cuttingedge, and a top covering the upper portions of said mold-boards and projecting beyond the edges of the same, substantially as described.

JOSEPH \VOOLLEY.
