SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 281,954, dated July 24, 1889.

Application filed March 29, 1953. (No model.)

To 0. whom it may concern Be it known that 1, WILLIAM H. H BAKER, a citizen of the United States of America, residing at Freeport, in the countyof Stephenson and State of Illinois, have invented certain new and useful Improvements in Snow- Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or fig ures of reference marked thereon, which form a part of this specification.

This invention relates to a snow-plow and track clearer adapted to remove banks or drifts of snow from railways, its object being to take the snow from the bank in the front of the plow and deposit it to the rear or upon one or both sides of the track.

The invention consists in certain novel constructions and combinations of devices, which will be hereinafter fully described, and pointed out in the appended claims.

In the accompanying drawings, Figure l is a perspective view of a snow-plow constructed according to my invention. Fig. 2 is a side elevation of the same. Fig. 8 is a rear view with the side boards let down. Fig. 4. is atop view. Fig. 5 is a bottom view of the snowplow detached.

The letter A designates an ordinary platform-car, provided with a firmly-braced trans verse wall, 13, a little to the rear of its midlength, and with hinged side boards, 0, arranged to close up against the ends of said wall. From the lower edges of these side boards project short arms 0, carrying at their outer ends short thimbles or sleeves d, and when the side boards are raised these short arms project downward through openings in the platform and alongside the side beams of the car in such position that the thimbles or sleeves may be engaged by hooks 6, projecting from latch-rods E, mounted in guides e" on the outer surface of the car-beams. These latch-rods extend rearwardly, and are connected together at their rear ends by a cross-bar, E, arranged under the platform in rear of the transverse wall 13, and having its ends extending through opening c' formed in the side beams of the car.

A hand-lever, F, is pivoted in brackets, so that the lever may be used for moving the latch-rods to engage or disengage the thimbles, as desired, for holding up the side boards or allowing them to fall. A spring is attached to the cross-bar E, and to a pin projecting below the platform, said pin being arranged to throw the latclrrods normally forward, so that their hooks will be held in engagement with the thimbles. A notched arc-bar, F", is arranged to engage the lever F and hold it in any position desired. Another hand-lever, G, is pivoted on the platform in rear of the transverse wall B, and has secured to it two ropes, which pass over pulleys g and g, from which they pass, respectively, around pulleys g and g, mounted side by side upon the top of the transverse wall at its middle, and thence pass over pulleys g and g at the ends of said wall, and are attached to the tops ofthe side boards.

A notched arc-bar, G, is arranged to engage the lever G and hold it in its rearward position, as shown in Fig. 2, when the side boards are raised.

To the front of the car is firmly secured a snow-scoop, H, consisting of an inclined floor, h, supported by a frame work composed of oblique side beams, h, rear and front beams, cross-bars, and side boards. The rear beam of the snow-scoop is firmly bolted to the front end beam of the car, and the front portion of said scoop is braced by curved iron braces l, which extend from the front to the rear ends of the side boards, which also serve as cutters.

The letter M designates the snow-plow, which is composed of two shares or wings, m, con nected at an angle in front and diverging rearwardly, their rear ends extending nearly to the side boards. These shares or wings are thoroughly braced at their tops by a cross-bar, a, and their lower edges are thoroughly braced.

At the middle of the front cross-baris mounted a grooved wheel, g, which runs upon a single rail, 0', arranged longitudinally at the center of the car-platfor1n, and near the ends of the rear cross-bar are mounted wheels 8, which run upon the platform at each side of the rail. By means of these wheels the snow-plow may be adjusted forward or rearward, as desired. The cross-bars are provided with bolt-holes, in which pass bolts, which also pass through holes in the car-platform and serve to hold the plow securely upon said platform. There are two longitudinal series of these holes in the platform, so that the play may be adjusted in different positions in relation to the scoop.

The snow-scoop may be provided with a small pair of truck-wheels, XV, to run upon the railway-track and support the forward end of said scoop, which should be arranged to stand in close proximity to the track.

The complete snow-plow and track-clearer, as now described, is to be coupled to a locomotive and the scoop driven into the snow which it is desired to remove, the side boards having been previously lowered. A load of snow is guided upward by the scoop, and as it is forced onto the platform it is divided by the snow-plow, and parts guided each way by the shares and dumped over the edges of the car and along the sides of the track, where the drift of snow is very deep, rising above the top of the snow-plow M. Said plow should be adjusted considerably to the rear of the scoop, so that the top of the bank will not fall over behind it; but where the track is covered to the depth of a few feet the plow M may be arranged close in the rear of the scoop, and a continuous charge of snow elevated by the scoop will be divided and distributed evenly along the sides of the track, thus making a clear path for trains.

The side boards may be adjusted horizontally, and will then cause the snow to be dump ed farther away from the track than if they hung down vertically.

The services of two or three men may some times be necessary behind the plow M to keep the platform clear of snow.

I reserve the right to make subsequent application and claim the novel features and combination shown or described but not specifically claimed.

Having now fully described my invention and explained the operation thereof, I cl aiml. The combination, with the platform-car provided with a snow-scoop and "the single longitudinal rail, of the double-shared snowplow provided with the grooved wheel to run upon said rail, and the two side wheels to run upon the platform, and means for securing said snow-plow in different adjustments upon the platform, substantially as described.

2. The combination, with the platform-car and its hinged side boards, provided with the projecting arms carrying latch thimbles or sleeves, of the latch-rods moving in suitable guides and provided with hooks for engaging said thimbles or sleeves, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

XVILLIAM H. H. BAKER.
