SPECIFICATION forming part of Letters Patent No. 256,451, dated April .18, 1882.

I Application filed October 26, 1881. (No model.)

To all whom it may concern:

Be it known that I, SILAS ADAMS, residing at Gardner, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvementsin Snow-Plows, of which the following is a specification.

My invention relates to improvements in the kind of snow-plows used on common roads and sidewalks.

The objects of my improvements are, first, to provide a cheap and convenient implement for breaking roads in the snow, which will be free from the dangerous and very annoying ridges or cores always existing in snow-roads broken out with devices mounted upon runners or traveled principally by two-horse teams; second, one which may be profitably used for smoothing snow roads which have become out of repair by reason of thaws, holes, 860.; also one pro-eminently adapted to clearing snow from sidewalks. Iattain these objects by the mechanism illustrated in the accompany ing drawings, in which similar letters refer to similar parts throughout the several views.

Figure 1 is a vertical longitudinal section of forms of my improved snow-plow; Fig.2, a plan, and Fig. 3 a front elevation.

A is a movable colter, fastened to the fore end of the plow by a hinge, and is moved to the right and left for the purpose of cleaving the snow, and also forshearing off the same from either side to widen the road after being broken through.

J is a lever which moves the colter.

I is the pivot on which the lever turns, and H isaloop by which it is engaged with'the colter.

E is the bottom or platform on which the driver stands, managing his team and also the lever J. This platform is entirely smooth on the bottom surface, turning up slightly at the fore end, and being drawn over the road-bed,

This is an implement some six feet long, three feet high, five feet wide at the rear end, and coming to a point forward, and made most- ]y of boards. The bottom boards are screwed to the cross-bars of wood, making a platform. To these bars are screwed the posts, to which are screwed the side-boards or moldboards. This forms the body, open behind. To the fore end of this is fastened by hinges the thin cutter or colter, some eighteen by thirty inches, moved right and left by a lever device in the hand of the teamster, who rides inside on the platform. This colter cuts and divides the snow six or eight inches above the ground, and the mold-boards crowd the snow outside of the road, while the flat bottom, turning up before, passes over the residue, pressing it down level fora good road-bed, free from that annoying ridge so common and so dangerous. Y

I am aware that previous to my invention double mold boards, movable colters, and wings have been frequently applied in various ways to snow-plows. I therefore do not claim any patent thereon, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a snow-plowhaving a fiat bottom without runners and adapted to press uniformly over the road-bed, of a colter fastened to the fore end of the plow by strong hinges with operating devices, as set forth.

2. The combination, with a snow-plow having a flat bottom without runners and adapted to press uniformly over the road-bed, of a colter and operating devices, as described.

3. The combination, with a snow-plow hav ing a flat bottom to run upon the snow and SILAS ADAMS.
