IMPROVEMENT m sNow-PLows.

Specification forming part of Letters Patent No. 49,216, dated August 8, 1865; reissue No. 7, 109, dated May 16, 1876; application filed April 24, 1875.

To all whom at may concern:

Be it known that I, AENEE L. BAUSMAN, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Improvement in Snow-Plows; and I do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a side view of the device e1n bodying my invention. Fig. 2 is a horizontal section thereof in line as m, Fig. 1.

Similar letters of reference indicate .corresponding parts in the two figures.

My invention relatesto a device for removing snow from-railways. It consists in constructing the plow or device with mold-boards or wings, having double walls which form a chamber for steam or hot air, by which the mold-board or wings may, when the plow is in use, be kept in a heated state, and the snow prevented from adhering theret It also consists of rotaryblades, which are located at the rear of the plow so as to extend over the rails, and thus shovel snow therefrom, in combina tion with rotary brushes, likewise located at the rear of the plow so as to extend over the rails, and thus sweep the snow therefrom, a shovel and brush for each rail being mounted on the same axis, whereby the advance plow separates the bank of snow, the shovels remove the solid portions of the snow left on the rails, and the brushes clean the rails of the loose particles, the motion of theshovels and brushes being at a right angle to the line of the rails.

. Referring to the drawings, A A represent ner, to support two shafts, D D, parallel with and directly over the two lines of rails of the road. These shafts D D carry radial blades E, which may be of cast metal or heavy rolled metal platesfour blades to each shaft will probably be sufficient. These blades serve theoffice of shovels. 0n the shafts D there are secured brushes F, which are'constructed of flat wires 1), driven or otherwise fitted in wooden cylinders 0. These brushes, however, may be constructed in various ways. On each shaft D there is keyed a pinion, d, and these pinions gear with wheels 6 c on a shaft, G, which receives motion by a belt, f, or by gearing from the axle 9, when the plow advances. The plow removes and casts aside the superincumbent mass in front. The shafts D D rotate and impart rotary motion to the blades, and the snow on top of the rails will be shoveled to the side thereof. The brushes cleanly sweep the snow from the track to the side thereof. In consequence of keeping the moldboards or wings in a warm or heated state by means of the steam or hot air introduced thereinto, into the space a, the snow is prevented from adhering thereto and caused to slide freely oif, thereby enabling the plow to work efficiently at all times. A safety-valve may be employed at the top of the plow, or the rear of the wings may be perforated with small holes t, for the escape of the steam or hot air.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A snow-plow for railroads, constructed with double walls, to admitof a steam or hotair chamber between its exterior surfaces, for

the purpose of keeping said surfaces in a heated state, substantially as set forth.

2. Rotary shovels, in combination with rotary brushes, placed at the rear of a plow and over the two lines of rails, the shovel and brush for each rail being mounted on the same shaft D, and operating substantially as and for the purpose set forth.
