WILLIAM W. OSBORNE, OF KANSAS CITY, MISSOURI.
SPECIFICATION forming part of Letters Patent No. 250,164, dated November 29, 1881. I Application tiled October 5,1881. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM W. OSBORNE, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in Snow-Flows, of which the following is a full, clear, and exact description.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a sectional side elevation of my improvement. Fig. 2 is a side elevation of the same, part being broken away. Fig. 3 is a plan view of the same, partly in section, through the line mm, Fig. 2.
The object of this invention is to effect the removal of deep snow from railroad-tracks in a speedy and economical manner.
Arepresents the frame of the snow-plow, which is made triangular at bottom and top, and with its top much smaller than its base, so that the forward edge and the sides will incline upward and inward. The frame A can be made of wood or iron, and must be of sufficient strength to withstand the pressure of the snow. The inclined sides of the frame A are covered with boiler-iron B, and to the said boiler-iron B are secured, by metal straps or other suitable means, coils of steam-pipe 0, two inches (more or less) in diameter, and of sufficient strength to resist a steam-pressure.
of two hundred pounds (more or less) to the square inch. The pipes O are placed close together, and are made in sections, the upper end of the pipe of each section being connected with the steam-space of a boiler, D, by a pipe, E, so that steam can be sent through all the pipes or only through the lower sections, as the depth of the snow may require. The forward bends of the horizontal pipes G are formed of bent couplings H, to prevent the said pipes from being weakened by being bent. The couplings H lie close together and add to the strength of the nose of the plow, and render it less liable to be injured by striking against ice or other solid obstructions. The pipes G are covered and protected by a casing, F, of sheetiron, secured to the inner plates, B, by bolts or rivets. The plow is mounted upon trucks G in such a manner-that its base may be about two inches above the track.
The steam can be supplied by a boiler, D, placed within the plow, or by the boiler of a locomotive. In the latter case a second loco motive will be required to push the snow-plow forward. When the boiler D is placed within the snow-plow water-tanks and receptacles for fuel should also be placed within the said plow for convenience in keeping up a supply of steam.
The pipes E should be supplied with cocks, so that the passage of the steam can be controlled as may be required.
With this construction the surface of the plow in contact with the snow will be kept hot, so that the snow will slide off the said surface freely, and will be more or less melted, so as to pack and remain in place when thrown from the track.
I am aware that it is not new to use horizontal steam-pipes connected in front by return- N bends, and arranged in planes parallel to each other and to the track, or to use a double casing divided into channels for the reception of steam; but D What Icelaim as new andof my invention 1s 1. A snow-plow constructed substantially as herein shown and described, consisting of the frame, the inner iron plates, the coils of steam-pipes, and the outer sheet-iron casing, as set forth.
2. In a snow-plow, the combination, with the trucks G and the boiler D, of the frame A, the inner iron plates, B, the coils of steam-pipe O, and the outer sheet-iron casing, F, substantially as herein shown and described, whereby the surface of the plowin contact with the snow will be kept hot, as set forth.
