f This invention relates to snow plows for steam and street railways, trucks and .the l1ke and the principal object of the inventlon 1ste provide spiral conveyor means for forcing the snow to one or both sides of the track or road.

Another object of the invention is to pro- 'vide blower means for receiving the snow from the conveyor means and for blowing the snow to a distant point. o.

In a' further aspect, the invention contem plates a novel method of removing snow from road surfaces, whereby the snow is completely -tkenup' and subsequently automatically scattered at points remote from the road bed so as to eliminate banks and piles at the side of the road.

This inventlon also consists 1n certain other features of construction and in the combina-y tion and arrangement of the several parts, to 2o" be hereinafter fully described, illustrated in theaccompanying drawings and specifically pointed out in theappended claims.

In describing my invention in detail, reference will behad to the accompanying drawings wherein like 'characters denote like or corresponding parts ythroughout the several views, and in which p 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. v

Figure 3 is a sectional view taken onf-line 3-7-3 of Figure 1.

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

Figure 5 is an end view ofvthis form.

FigureG is a sectional view of a further modification.

Figure 7 is a sectional view through this modification. l

Figure 8 is a sectional view of another modification. u

Figure 9 is a sectional view through this modification.

In these views 1 indicates a casing which 'has its lower portion of substantially semi' cylindrical forinv in cross section with its up per part inclinin'g upwardly andoutwardly as at 2. This casing is supported in any suitable manner in front of the engine, street car, automobile, or other vehicle so that it will scoop u the snow from the track or road in front o lthe Vehicle. As shown in Figure l the casving 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 broughtadjacent thesurface .to be cleared of snow. A shaft 5 issuitably journaled in the said casing and this shaft carries the right and 60 left hand screwed conveyors which extend from a point adjacent the center` of the shaft to the ends of the casing. This shaft is connected in any suitable manner with the source of power so that the shaft may be rotasted'. y

It will thus be seen that the snow drifts or deposits will be cut by the blades of the conveyors and the snow thus severed will be forced towards each end of the casing by the conveyor blades. If the ends of the casing are open the snow will be deposited on each side of the track or road, but this is undesirable since it lines the edge of the road with heavy banks, and if the latter freeze the plow could not force through to remove later snow deposits. y

I prefer, therefore, to attach a casing 8 at cach end of the casing l and to extend the ends of the shaft 5 through these casings. 80 These extended ends of the shaft carry fan blades 9 so that a blast is created in each casing to drive the snow delivered to the casings by the conveyors through the outlet lpipes 10 and the delivery pipe 11 whichV is 85 discharge it from the outlet 22 at the top Ael() This arrangement is perhaps the most e cient so that the fan 9 will throw the snow from each end of the casing as the snow is deliveredto them by the conveyors. I may place deector plates 13 aroundthe upper portion of ,the casing at the ends thereofto prevent snow from being thrown back lupon the plow or the vehicle. In this form a splder 14 is placed/at each end of the casing to carry 4 the journals for the shaft. p

In the modification shown in Figures 6 and 7 the shaft 5 carries but one conveyor blade' en through the snow on the track or road the' spiral screws will cut the snow and move it transversely of the road bed,-and if the blower device is used, the removed snow can be delivered to a distant point so as to remove the the danger of the banked snow at the side of track falling back upon the track, and blocking future passage of the plow.

In the modification shown in Figures 8 and 9 a double conve or is used which is so arranged as to fee the snow to the center of the ca sing. 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 ther;E

o the fan easing. This fan has its shaft 23 geared to the shaft 24 on which the conveyors 25are carried. The fan shaft is connected in any desired manner with a source of ower.

of all the forms illustrated. By moving the snow toward Vthe center of the plow from each end, the plow is more readily guided as the force on each side is substantially the Same. Thus the tendency of the vehicle to slip olf or toward the edge of the road is avoided.

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

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

WVhat I claim is 1. A snow plow of the class described comprising a horizontally arranged semi-cylindrical casing, a fan casing connected therewith, a spiral conveyor in 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 caslng.

A fan casing 2O is connectedwith outlet for the fan casing and means for y driving the fan and the conveyors.

s now remover of the class described comprising a casing, a horizontally arranged spiral-conveyor in said casing adapted to cut and feed snow transversely of the casing, a fan casing communicating with the horizontal casing and adapted to receive snowtherefrom, said fan casing having an adjustable discharge opening, and a fan' in the fan. casing for discharging the snow from the latter.

4. A snow remover of the class described comprising a casing, a spiral conveyor therein formed `of right and left hand parts and arranged to feed snow in opposite directions, a fan casing in the rear of the conveyor casing and communicating with the conveyor casing adjacent the point of meeting of the right and left hand parts of the conveyor, a fan in said fan casing, an outlet for the fan casing, and means for driving the fan and the conve or.

snow plow of the class described comprlslng a casing, a spiral conveyor therein formed of right and left hand parts and arranged to feed the snow to the center of the casin the axis of the conveyor being horizonta 1y arranged and extending transversely of the road bed, a fan casing .1n the rear of the conveyor casing and communicating with the center of said conveyor casing, a fan in said fan casing, an outlet for the fan casing, and means for actuating-the fan and conveyor. l
