IMPROVEMENT IN SNOW-FLOWS.

To all whom it may concern.-

Be itknown that I, J EREMIAH B. WILLIAMS, of MadisomDane county, and State ot' Wisconsin, have invented certain new and useful Improvements in Snow-Flows for Removing` Snow from Railways; and I do hereby declare that the following` is a full, clear, and exact dcscriptitn thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in which- Figure lis a perspective view; Fig. 2, a top plan view, and Fig. 3 a plan view of a modified form of the same.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

A represents the forward truck of a car. To the front of this car A is secured by a suitable hinge or pivot-joint a snow-plow, B, consisting of a metallic scoop or plate projecting forward, the front end resting upon or just above the rails of the track, and its rear portion being curved upward and outward in the form of a double-mold-board plow, as shown. The corners at the rear of this plate B are curved slightly forward, as shown at a.

C represents a scoop-wheel of peculiar construction. This wheel has four or more wings projecting radially from its hub or sh aft, which wings are curved on their edges somewhat in the form of a scoop, as clearly shown in the various figures. By having the wings of the wheels thus formed they are adapted to the concave surface of the plow B, so as to sweep close to its surface in their revolution, and at the same time present acurved or scoop-shaped surface to the snow, by which the latter is more readily seized and more thoroughly removed. Two of these wheels are mounted upon their respective shafts b in such a way that they occupy a position above and in front ot' thc plow B, the wings of said wheels revolvingin close proximity to the upper surface of theplow B. The shaft b extends through anl opening in the rear portion of the plow B, as shown in Fig. l, and bein g suitably mounted in the frame of the truck A extends back to a point near the rear axle thereof, as shown ,in Fig. l. A beveled gear, c, on the axle D gears into the pinion e on the end ofthe shafts b, and as the car advances motion is thus conveyed to the wheels C.

Fig. 3 represents my invention applied to a car, in which the snow-plow B is so constructed as to deliver the snow taken up by it all on side of the track. This is accomplished by so forming or curving the scoop portion of the plow that its wing or mold-board portion shall stand diagonally to the track in a single direction instead of in two directions, as in the Figs. l and 2. This is intended to be used when there is a doubletrack railway, in which case it is necessary that the snow should be delivered on the side opposite to that of the adjoining track. Either one or two wheels may be used with this form of plow, as may be found most expedient.

It will be observed that there are two forms of wheels shown. (See Fig. 2, in which C and 02 indicate the two wheels respectively.) C is shown longer than O2, and has the rear end of its wings rounded, as shown in Figs. l and 2, by which it is brought in closer proximity to the plow B at that point. A lever, h, is secured to the platform or body of the car. A rod, i, connects this lever to the plow B, by

- which means theplow may be raised or lowered, as may be desired.

The operation is as follows Vhen the track is obstructed by drifts or banks of snow, the car provided with my improvement is put in motion, and as it advances into the drift the scoop or plow B scrapes the snow up, and lifting it from the track forces it back upon the plow, where the revolving wheels G seize hold of it by means of their scoopshaped wings and throw it outward to cach side clear from the track. These wings may be made of such width as to cause them to interlock or overlap, care being taken to soadjust them upon their shafts that the wings shall not come in contact.

In the ordinary snowplow, if the drift be high the forcing of the plow into it only serves to pack the snow more solidly on the track. By my improvement the plow is relieved from the pressureof the accumulated mass of snow by means of the revolving wheels, which, revolving rapidly, lift the snow therefrom and remove it to either side. Even in the case of a hard drift the wheels C will cut or borc a assage into or throughv the drift, cutting and.

)osening up the mass, when, by the combined ction of the wheels C and the plow B, the now will be displaced and crowded to each side f the track.

If desired, the scraper d and brush f may be ecured to the truck in such a. position as to lear the rail of any particles of snow which lay be left adhering after the passage of the low B.l v

Having thus fully described my invention, :s construction and operation, what I claim as ew, and desire to secure by Letters Patent,

1. The digging or excavating wheel C, having its wings attached in line with its axis, and having the outer edges of said wings formed scoop-shaped or curved, as shown.

2. The wheel C, in combination with the plow B, constructed and operating substantially as set forth.

3. Pivoting the plow B in such a way that it can be raised or lowered by means of the lever h and rod t', substantially as shown.'
