IMPRQVEMENT IN SNOW-FLOWS FOR RAH-WAYS.

t'pccification forming part of Letters Patent No.1 10,446; dated December 27, 1870.

To all whom it may co'i'we'rn:

Be it known that I,'Tn3EnIUs DOUGHERTY, of the city and county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Snow-Flows; 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 and use the same, reference being had to the accompanying drawing making part of this specification, in which-- I Figure 1 is a perspective view of the device illustrating my invention. Fig. 21s a bottom view.

Similar letters of reference indicate correspondin g parts .in the two figures.

My invention consists in a railway snowplow which is independent of the locomotive, and in which its shovels receive rotary motion through intermediate gearing by -means of drivin g-rods which are attached to the wheels of the plow, and to receive power from the lo comotive. By this means the wheels of the plow cannot s1ip,.and thus prevent the rotation of the shovels. Side pieces or wings are hinged to the plow, and have springs ar= ranged therewith, so that snow will bepressed outside of the track, while the win gs will give to posts or other obstacles on the road.

In the drawing, f represents the forward end of the plow, which is inclined, and -by which the snow is raised and delivered to the revolving shovels b.- Each shovel consistsof suitably-forniedblades,radiating from asleeve, c, which is made to slip on a shaft, 0, which passes through the platform 1' of the plow. These sleeves are notched or perforated, and by means of keys or bolts j are firmly secured to their shafts 0, but are readily removable, when desired, for purposes of adjustment or repairs. Tothe shafts of there are fixed gear wheels 9 g, which mesh with similar wheels near the forward end of the plow to guide it upon the track and take the weight of the snow. To the sides of the plow are hinged wings k k, having springs so arranged that snow'will be pressed outside of the track, while the wings are not interfered with by posts, or otherwise along the road. a a are drivingrods which are secured to the running-wheels of the plow, and extend so as to be connected of snow around and about said shovels. I

obviate this great defect by the employment of the driving-rods a.

When the engine starts, therunning-wheels of the shovels will surely be rotated. The slipping tracks may cause theformer to fly, but this will not stop the shovels. Said running-wheels cannot slip owing. to their-connection with the engine.

It is evident that my device possesses superior advantages for the purposes intended, and when no longer needed its driving-rods are to be, detached from thelocomotive, and the plow, can then be moved out of the way and laid by for future-use.

What- I claim is- 1. The spring wings k. at, the side of the I plow, substantially as and for the purpose dey driving-rods a, arranged in relation to each otherand' to the running-wheels of the plow, substantially as andfor the purposes described. The above specification of my invention signed and. witnessed, at Philadelphia, this 13th day of August, A. D. 187.0.
