FRED D. LINTON,.OF TORONTO, CANADA.
ROTARY SNOW-PLOW.
SPECIFICATION forming part of Letters Patent No. 541,766, dated June 25, 1895.
Application filed February 23, 1895. Serial No. 539,389. (No model.)
To all whom it may concern.- Be it known that I, FRED DALLAS LINTON, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Rotary Snow-Plows; and I hereby declare that the following is a full, clear, and exact description of the same.
This invention relates to certain new and useful improvements in snow plows, and relates more particularly to the general construction and operation of the plow whereby.
the snow may be gathered from the front of an advancing plow and readily thrown to any required distance clear of the track and the object of the invention is to make a simple, effective and easily operated snow plow, which can be driven at any required speed and which can be adjusted to regulate the distance which the snow is to be thrown to the side of the road-bed; the whole device being hereinafter more fully set forth and more particularly pointed out in the claims. In the drawings, Figure 1 is a perspective view of the snow-plow looking at it from the front. Fig. 2 is a similar View showing the casing partially broken away to illustrate the discharge-chute. Fig. 3 is a perspective View of the snow-plow looking at it from the back. Fig. at is a cross-sectional view on the lines a a, Fig. 1. Fig. 5 is a perspective view of one of the rotary fans. Like letters of reference refer to like parts throughout the specification and drawings.
The fan consists of a hub A to the outer end of which is secured a series of radial spokes B, and to the inner end of which is secured a series of tangential spokes O, which correspond in number and location with the radial spokes B. The outer faces of the radial spokes B are all in the same plane, in order that the cutting blades D may be bolted or otherwise secured to them in their proper relation to each other. The tangential spoke 0 corresponding with its radial spokeB is in position on a line transversely crossing the horizontal axis of the hub A, and the side face of the radial spoke B and the side face of its corresponding tangential spoke O are in the same plane in order that the horizontal blade E may transversely cross the horizontal axis of the hub A. By arranging the the free revolution of the fan.
horizontal blades E transversely to the horizontal axis of the hub A, the requisite suction can be created to draw the snow from the front of the cutting blades into the fan chamber, and at the same time this arrangement of the horizontal blades E avoids any considerable resistance during the revolution of the fan. In addition to the suction created by the blades, the blades have a discharging force sufficient to throw the snow within the fan chamber out through the discharge chute in the top of the side of the body of the frame. As the force of the fans would be sufficient to throw the snow to a considerable distance from the plow, and when used in populated districts considerable danger would arise from the violent discharge of the snow, I find it advisable to regulate the distance which the snow is to be thrown, and this I accomplish by the means I hereinafter set forth.
The fan revolves in a fan chamber F formed in the body of the frame G, and this fan chamber is of a sufficient size to allow of In the top of the fan chamber F is an outlet portH which connects with a discharge chute I. The discharge chute I opens out through the top of the side of the frame G, and hinged to the top of the frame G and overhanging the outlet of the discharge chute I is a lid or cover J. Connected to the frame G and located one on each side of the lid J are two segmental plates K, and formed in each of the segmental plates K isaguide L. Connected to each side of the lid J and workingin its respective guide L is a pin M. Connected to the lid J isa lever Nby meansyof which the said lid Jis opened or closed; On each side of the opening of the discharge chute-through the top of the side of the frame G is a flange O for the purpose of breaking the wind from the discharge chute during the advance of the snow plow. Supporting the outer end of the V strength to the shaft, and prevents it sagging IOO and causing the blades of the fan to bind on the wall of the fan chamber. The rear end of the shaft P is journaled in a bearing R formed in the back of the frame G. The front of the frame G is provided with an outwardly flaring mouth S which scoops in the snow to the revolving fan or fans. The top of the mouth S is provided with an adjustable slide T, which can be raised or lowered as required. When the snow is of a great depth the slide can be raised to its fullest extent or completely removed if required in order that the revolving fans may cut into the full depth of the snow and discharge it through the discharge chute I. Again, when the snow is of only a slight depth it is necessary to lower the slide to approximately the depth of the snow, in order-that thelower part of the fans can cut the snow and suck it into the fan chamber, and discharge it through the discharge chute I. \Vithout the slide T the revolution of the fans when the plow was running through a light fall of snow would have a tendency to knock the snow to one side in place of sucking it into the fan chamber and throwingit out through the discharge chute. To allow of the adjustment of the slide T there is formed through the sides of the slideT and through the sides of the mouth S a series of holes through which are passed slit pins or bolts U. These allow of the convenient adjustment of the slide T, and at the same'time hold it securely to the mouth.
Imay find it advisable in place of using one revolving fan to use several fans in which case the construction and operation of each of the fans is similar to the one just described, each fan revolving in its respective fan chamber and discharging its contents through a discharge chute into the last or final discharge chute from which it is delivered. In this case the last or final discharge chute is of greater dimensions than the other discharge chutes, in order that the output from the remaining discharge chutes may be emptied into it without causing the snow to block.
When several rotary fans are employed there is mounted on the rear end of each of the fan shafts P a sprocket wheel V, and passing around the sprocket wheels V is a sprocket chain WV which engages with a sprocket wheel X mounted on the driving shaft Y one end of which is journaled in a bearing formed in the back of the frame G.
The operation of the device is as follows: Motion is transmitted to the shafts P of the fans, and the fans areset in motion. The cutting blades D break the snow and permit of its being sucked into the fan chambers by means of the horizontal blades E. The revolution of the horizontal blades E throws the snow from the fan chambers into the discharge chute where it is thrown with force to the side of the road bed. To regulate the distance which the snow is to be thrown I find it advisable to open or close the hinged lid J. By opening the hinged lid to its fullest extent the snow can be thrown to the greatest possible distance by the horizontal blades E, but by closing the lid J the distance which the snow is thrown is shortened, and by almost. completely closing the lid J the snow could be delivered almost at the side of the snow plow. It is necessary to provide some means for regulating the distance which the snow is to be thrown, in order that accidents will be avoided while the plow is passing through populated or built up districts.
I do not confine myself to driving the fans by any particular style of gear, as I may employ any convenient means which will successfully accomplish the purpose.
Where a series of fans are employed I find it advisable to drive the fans at different rates of speed; that is, the fans farthest remote from the delivery end of the discharge chute are driven at a much higher rate of speed than the fan contiguous to it, as the fans farthest remote from the delivery end of the discharge chute have farther to throw their output, and consequently require a greater force for that purpose.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A snow plow consistingof afan chamber, a fan within the fan chamber, consisting of a hub, a series of radial spokes connected to the outer end of the hub, a series of tangential spokes connected to the inner end of the hub, a blade connected to each of the radial spokes and arranged to transversely cross the horizontal axis of the shaft, a cutting blade connected to the outer side of each of the radial spokes and a discharge chute from the fan chamber, substantially as specified.
