RAIL=SCRAPER AND SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 353,738, dated December 7, 1886.

Application tlled April 10, 1886.

To all whom, it may concern:

Be it known that I, ELISHA B. DURFEE, a citizen of'the United States of America, residing at Lincoln, in the county of Lancaster, in the State of Nebraska, have invented a new and useful Rail scraper and Snow-Plow, of which the following is a specification.

My invention has relation to improvements in rail-scrapers and snow-plows for use on railways and tram ways; and the objects are, first, to provide a device of the kind named which will clear the rails from snow, slush, andotherobstructions accumulated thereon at a less expenditure of power than is required by the devices ormachines heretofore known and in use; and, second, to provide a rail-scraper or snow plow which will also operate as a brake. and thus dispense with theusual car-brake. These objects I attain by the mechanism illustrated in the accompanying drawings, wherein- Figure 1 is a side view of my invention attached to a car in operative position. Fig. 2 is a perspective view of the upper and stationary wheel-case. Fig. 3 is a perspective view of the lower and adjustable wheel-case. Fig.

4 is a side view of the plow-point or railscraper, shown on a larger scale than in the other figures. Fig. 5 is aside view of the several parts united. Fig. 6 is a top view of the plow-point 01' rail-scraper. Fig. 7 is a side view of a sectional case and scraper applied to a car. Fig. 8 is a perspective view of a sectional stationary wheel-case. Fig. 9 is a side view of a sectional scraper, showing the upper and lower wheel-case united and the point attached. Fig. 10 is a perspective view of a sectional adjustable wheel-case; and Fig. 11 is a perspective view, showing in detail the mechanism for adjusting the lower wheel-case, the ends of the operating-rod being broken off.

In the drawings, similar notations refer to the same parts, and reference being had thereto, the letter A designates the upper and stationary wheel-case, consisting of two substantial metal plates having their ends united by means of bolts or other proper detachable fastenings, substantially as seen at 1, said plates being shaped so that when united they shall surround the car-wheel. For the purpose of atfording space for the axle and axle-box of the car, the plates are cut away, as seen at 2 3; and in order that the case may be readily fixed to the timbers of the case, the upper edges are flanged, as seen at 4, the flanges being provided with bolt-holes to take the fastening means. In the inner wall of the stationary wheel-case is formed an opening or bearing, :10, to receive the journal of the means for raising the adjustable case, as will be hereinafter more fully stated. In each wall of the stationary wheel-case is cut a slot, y, vertically arrangedto take the lugs or bolts projected from the outside of the adjustable wheelcase.

The letter B designates the lower and adj ustable wheel-case. This consists of two substantial metal plates secured together firmly, but detaehably, by any proper means, and in crosssection is the same configuration as the upper case, but is made smaller, so as to fit within the upper case and slide up and down therein. The junction or lap of these plates is preferably in the middle of the sides, in order that the ends may be clear to receive the plowpoint or scraper and have it secured thereto. The ends of this adjustable casing may be cut away, as seen at 5, to receive the plow, and from the sides are projected lugs or bolts 6, which set within the slots g of the upper case and hold the lower case from tilting, and also serve as guides in its movements up or down. To the side of this lower case is fixed a rackbar, I), which is engaged by the gearing having its bearing in the case, and by means of which the lower case is adjusted.

The letter O designates the plow-point or scraper, formed with a shank to set in the end of the lower case, and is secured therein by bolts or other means. The projecting part or point 7 of the plow is shaped to enter under any substance in front of the wheel and cast it aside. To the rear of the plow-point or scraper O is fixed the flange-scraper G, to clear or scrape the flange of the rail in front of the flange of the car-wheel free from ice or snow or other obstruction.

The letter a designates the crank-bar set in the end of the car and provided with a gear 011 its lower end, which meshes withagear on the bar A, journaled under the car, as seen at a. This bar a is provided with a screw or ICO gear, 8, which meshes with a gear, 9, on a I do not claim as new, except as in combination with my invention, this mechanism for operating the lower case, but simply adopt it as a means for effecting the adjustment of the .lower case.

The mechanism for raising or IOWBIlIlgiZhQ deep, and to lessen the danger to any living object falling in front of the wheel by throwing it off the rail.

The plates forming the wheel-cases are de tachably secured together to permit them to be attached and detached without raising the car from the rail. The plow or scraper is not specially intended to throw the accumulations permanently from the rail, but rather to clear the path of the wheel.

v The wheel-case B, with the plow or scraper united thereto, can be raised and lowered at will, and may be pressed on the rail,and serve in this position instead of the ordinary brake. If the ordinary brake is used, the ends of the wheel-case must be provided with openings to take the brakeshoe. I In Figs. 7 to 10, inclusive, of the drawings I have shown my invention as sectional and of such form as is particularly applicable to cars which are turned about and always run with the same end forward. The device in tion the cases may be formed of one plate bent in shape,substantially as seen in the drawings.

What I claim, and desire to secure by Letters Patent, is-

1. The combination of the fixed wheel-case A and the wheel-case B, detachably and adjustably connected to the wheel-case A, substantially as described.

2. The combination of the fixed case A and i the wheel-case B, detachably and adjustably secured to the wheel case A, and a flangescraper, O, substantially as described.

3. The combination of the fixed wheel-case A, the wheel-case B, detachably and adjustably secured to the wheel case A, the scraper O, and flangescrapertl, substantially as described.

4. The combination of the Wheelcase A, fixed to the body of the car, and provided with gear 9, the wheel-case B, adj ustably-set about the wheel-case, A, and provided with rack-bar b, the plow or scraper G on the end of the case B, and provided with a flange-scraper, O, and means for revolving the said gear and raising and lowering the case B, substantially as described.
