SNOW- PLOW.
SPECIFICATION forming part of Letters Patent No. 394,244, dated December 11, 1888.
Application filed March 19, 1888. Serial No. 267,684. (No model.)
To @ZZ whom it may concern;
Be it known that I, EDWARD P. CALDWELL, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain Improvements in Snow-Plows, ol which the followiu is a specification.
The object of my invention is to provide a machine for clearing the snow from railroadtracks; and I seek to provide a machine by means of which the track may be cleared from i In the d rawings forming a partof this specig ication, Figure l is a sectional elevation of a snow-plow cnnbodying my invention. Fig. 2
is a front elevation of the same. Fig. 3 is a front elevatiml of t-hc cutter, showinga modified arrangement of the knives.
In the drznvings, 2 represents a portion of a suitable car, upon which may be supported y both the snow-plow itself and the means for drivin it. Mounted in suitable standards, 3, upon this car `is alongitudinal shaft, 5, that projects for a suitable distance beyond the forward end of the car. This shaft may be driven by any suitable means, but preferably from an engine arranged upon the car 2. Secured to the forward end of the shaft 5 is a conical cutter, formed, preferably, of a series of knives having their cutting portions arranged at an angle to the surface of the cone, and having open spaces between through which the snow may pass to the interior of the cutter. Spiders 9 are preferably arranged upon the shaft 5 at suitable distances apart, and a block, ll, is arranged at its forward end, and to these spiders and to this block the knives 7 are preferably secured. In the rear of the conical cutter I prefer to arrange suitable elevators for taking up the them,
snow aft-er it has passed through the spaces between the knives an d to the rear of the cutter, and carrying it up and throwing itout at the side of the track. Any suitable means may be used for thus removing the snow, such as a conveyer, an exhaust-fan, or an elevator. I have shown in the drawings two elevators, one arranged at cach side of the machine. These elevators each consist of a belt, 13, preferably formed of rubber, passing around suitable rolls at the top and bottom of themachine. A series of buckets or slats, l5, are secured upon this belt. The elevators may be driven by a sprocket-chain, IT, from the shaft 5. The snow, as it falls into the space behind the conical cutter, is taken up by these elevators, carried upward and dumped on both sides of the track. A suitable apron, 19, is preferably arranged at the bottom and sides of the conical cutter, as shown in Figs. I and 2. rlhe apron is provided with acutting-edge at. the bottom, and may be at the sides. The knives 7 may be straight, as shown in Figs. l and 2, or they may be of spiral form, as shown in Fig. The conical form of the cutter permits it to be pushed easily into the snow, and but a small amount of power will be required to force the snow-plow through a drift of any size. The cutter being pushed into the snow is rapidly rotated as it is advanced, and the snow is forced in through the open spaces between the knivesinto the interior of the cutter and passes to its rear end, where it is taken up by the elevators in the manner already described.
The apron 1.() trims off the snow at thebottoni and the sides of the cut and leaves it with sloping banks, which are not as liable to IOO hollow conical cutter open at its rear end and formed of the series of knives 7 arranged with open spaces between them, and means for discharging the snow that passes to the interior and out of the rear end of said cutter, substantially as described.
2. The combination, in a snow-plow, of the hollow conical cutter open at its rear end and formed of the series of knives arranged with open spaces between them, means for rotating said cutter, and an elevator for raising and discharging the snow, arranged in the rear of said cutter, substantially as described.
3. The combination, in a snow-plow, of the hollow conicalY cutter open at its rear end and formed of the series of knives 7, arranged with the open spaces between them, means for rotating said cutter, and the bottom Vand side aprons, l 9, substantially as described.
4. The combination, in a snow-plow, of the EDWARD P CALDWELL.
