ATTORNEY WITNESSES UNITED STATES HARRY D. CURTIS, OF OSEKOSH, WISCONSIN.

SNOW REMOVER.

To all rv/mm it may concern:

Be it known that I. HARRY D. Culrris, a citizen of the United States, residing at ()shkosh, in the county of Winnebago and State of \Visconsin, have invented new and useful improvements in Snow Removers, of which the following is a specification.

This invention relates to snow plows for steam and street railways, trucks and the like and the principal object of the invention is to provide spiral conveyor means for forcing the snow to one or both sldes of the track or road.

Another object of the invention is to provide blower means for receiving the snow from the conveyor means for blowing to a distant point.

This invention also consists in. certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which-:

Figure 1 is a sectional view showing my blower located in front of a locomotive, the

section being taken on line 1-1 of Figure 2..

Figure 2 is a sectional view of one form of the invention.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Figure 4 is a sectional view showing a modified form of the plow.

Figure'5 is an end view of this form.

Figure 6 is a sectional view of a further modification.

Figure 7 is a sectional view through this modification.

Figure 8 is a sectional modification.

Figure 9 is a sectional view through this modification.

In these views 1 indicates a casing which has its lower portion of substantially semicylindrical form in cross section with its upper part inclining upwardly and outwardly as at 2. This casing is supported in any suitable manner in front of the engine or street car or other vehicle so that it will scoop up the snow from the track or road in view of another Specification of Letters Patent.

front of the vehicle. As shown in Figure 1 the casing is attached to the engine by the arms 3. The lower edge of the casing is provided with an adjustable shoe 4 so that the shoe may be brought adjacent the surface to be cleared of snow. A shaft 5 is suitably journaled in the said casing and this shaft carries the right and left hand screwed conveyors 6 which extend from a point adjacent the center of the shaft to the ends of the casing. This shaft carries a gear wheel 7 which is connected in any suitable manner with the source of power so that the shaft may be rotated.

It will thus be seen that the snow scooped up by the casing will be forced towards each end of the casing by the conveyor blades and if the ends of the casing are open the snow will-be deposited on each side of the track or road.

I prefer, however, to attach a casing 8 at each end of the casing 1 and to extend the ends of the shaft 5 through these casings. These extended ends of the shaft carry fan blades 9 so that a blast is created in each casing to drive the show delivered to the casings by the conveyors through the outlet pipers 10 and the delivery pipe 11 which is connected with said pipes 10 by the rotary elbow 12. In this way the snow may be dellvered at any desired point or either side of the road bed.

In the modification shown in Figures 4 and 5 the ends of the casing 1 may be left open so that the fan 9' will throw the snow from each end of the casing as the snow is delivered to them by the conveyors. I may place deflector plates 13 around the upper portion of the casing at the ends thereof to prevent snow from being thrown back upon the plow or the vehicle. In this form a spider 14 is placed at each end of the casing to carry the journals for the shaft In the modification shown in Figures 6 and 7 the shaft 5 carries; but one conveyor blade 6 which delivers the snow to one end of the casing. The gear 7 is located at one end of the shaft and a fan 9 may be connected with the other end so as to deliver the snow received from the conveyor t0 the outlet pipe 10. I may use scooping side plates 15 at the ends of the casing for protecting the journals and the gear and fan from the snow, said plates forcing the snow to the conveyor. 4

It will thus be seen that driven through the snow on the track or road the conve or means will force the snow to each side the track or road or to one side thereof and if the blower device is used this snow can be delivered to a distant point so as to remove the danger of the banked snow at the side of the upon the track.

In the modification shown in Figures 8 and 9 a double conveyor is used which is so arranged as to feed the snowto the center of the casing. A fan casing is connected with the rear of the conveyor casing, at the center thereof, and the fan 21 therein acts to draw the snow from the'conveyor casing'and then discharge it from the outlet 22 at the top of the fan casing. This fan has its shaft 23 geared to the shaft 24 on which the conveyors 25 are carried. The fan shaft is connected in any desired manner with a source of power.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily'apparent.

track falling back as the plow is guano? I desire it to be understood that I may make changes in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended clalms.

What I claim 1s:

1. A snow comprisin a horizontally arranged semicylindrica casing, a fan casin connected therewith, a spiral conveyor 1n the first mentioned casing a fan in the. fan casing, means for actuating the conveyor and fan and an adjustable conduit connected with the fan casing.

2. A snow plow of the class described comprising a casing, a spiral conveyor therein formed of right and left hand parts and arranged to feed the snow to the center, a fan casing in the rear of the conveyor casing and connected with the center of said conveyor casing, a fan in said fan casing, an outlet for the fan casing and means for driving the fan and the conveyors.

In testimony whereof I ,aflix my signature.
