JEAN BAPTISTE MARTIN, OF ST. POLYCARPE, QUEBEC, CANADA.

SNOW-PLOW.

T all whom it may concern:

Be it known that I, JEAN BArTIs'rn MAR- TIN, a subject of the King of Great Britain, residing at St. Polycarpe, county of Sonlanges, in the Province of Quebec, Canada, have invented certain new and useful Tmproveuients in Snow-Flows; and I do hereby declare that the following is a full, clear, and

' exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to machines for removing snow from railway tracks, streets, roadways and similar places, and particularly to the general type of such machines commonly known as snow plows.

Broadly speaking, it comprises a casing adapted to house the working parts of the machine, means for supporting the casing, a chute leading from the casing, delivery spouts movably connected to the chutes, means for moving the delivery spouts to desired positions, means for deflecting snow from one to the other of the delivery spouts, means for forcing snow through the casing to the chute, means for guiding snow into the casing, and means for driving the several operating parts.

In order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings, like reference characters designate the same parts.

In the drawings: Figure l is a side elevation of the machine; Fig. 2 is a central vertical longitudinal section; Fig. 8 is a plan view; Fig. 4 is a rear end elevation; and, Fig. 5 is a front end elevation.

In the preferred form of the invention, a casing 1 is provided, in which the several working parts of the machine may be mounted. This casing is provided with a lower open end adapted to be fed forward against a snow bank, and has extending across this open end a plurality of substantially vertical cutting knives 2, by which the snow is separated into blocks as it comes through the opening. Vithin the casing and just above and behind the opening, is revolubly mounted a shaft 3, provided with a plurality of vanes 4, adapted to engage the snow and force it rearwardly through the machine.

Specification of Letters Patent.

Application filed March 8, 1909.

Serial No. 482,136.

Extending from blade to blade. are a plurality of cutting knives 5, adapted to divide the blocks of snow which pass to the interior of the casing 1. The snow is delivered by the vanes 4t to an inclined chute 6, terminating in two delivery spouts 7 pivotally mounted on rods extending vertically through the chute. The pivotal mounting of these spouts allows them to be swung toward one side or the other of the machine, as may be desired, for delivery of the snow at the sides of the machine. To effect the swinging movement of the spouts, a lever 8 is connected to a rod 9, extending through the chute and in alinement with the pivot rods of the spouts 7.

A blade or bar 10 is secured to the rod 9 in such position that it lies between the adjacent faces of the spouts 7. Consequently, movement of the blade 10 will effect a like movement of the spouts 7. A large deflector plate 11 is fixed to the opposite edge of the rod 9, and is so constructed as to direct all snow entering the chute into either of the spouts 7, as may be desired, or, if preferred, to allow the snow to pass equally into the two spouts. It will be noticed that the plate 11 moves simultaneously with the blade 10, though in the opposite direction. Consequently, if it is desired to deliver snow at the right of the machine, the lever 8 will be moved to swing the spout 7 toward the right, the bevel plate 11 moving at the same time toward the left, so that all of the snow will be deflected so as to enter the right hand spout 7 which is over the right side of the machine.

The connections between the spouts 7 and the chute 6 must be such as to make the spouts a practical continuation of the chute. The top and bottom connections may be very easily made by simply constructing the parts so that they overlap each other, the ends of the spouts sliding freely over the adjacent faces of the chute. The outer sides, however, present a difficulty. This difficulty is overcome by hinging the side plate 12 of the chute to the spout and mounting the edges of the side plate to slide freely in guides 18 on the casing 1. In order to prevent possible binding between the edges of the plates 12 and the guides 13, the plates may be provided with extensions 14 adaptedto pass through keepers or loops 15 on the casing 1.

As the machine is fed forward against a Patented Aug. 24, 1909.

snow bank, it is evident that the snow will tend to pile up over the top of the casin In order to prevent this, an inclined guice plate 16 has been connected to a late which is slidably mounted in the rear of the casing.

At the lower end of the chute 6, an opening is formed, and in this opening is mounted a shaft provided with a plurality of blades 17 This device is adapted to force upwardly into the end of the chute 6 any snow which may pass beneath the casing l as it is fed forward for the operation of the large blades 4.

Should it be desired to use the machine to load snow direct onto wagons or other vehicles, a hood 18 may be used. This hood is removably hinged to the top outer ends of the spouts 7. It is kept normally in a substantially horizontal position simply by the pressure of the air and snow rushing through the spouts while the machine is in operation.

The machine may be mounted on suitable trucks of well known construction, and the several parts may be driven by belt and pulley or any other suitable connections with a motor 19.

It is clear that changes may be made in the construction, arrangement and disposition of the several parts of the invention, without in any way departing from the field and scope of the same, and it is meant to include all such within this application, wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is 1- 1. A snow remover including a casing having an aperture adapted to be fed against the snow, rotating vanes within the casing adapted to feed the snow therethrough, and cutting blades connecting the outer edges of said vanes.

2. A snow remover including a casing having an aperture adapted to be fed against the snow, an inclined chute leading from said casing, means for forcing snow through said casing and chute, delivery spouts pivotally connected to said chute and adapted to swing horizontally, means for. swinging said spouts, and means for deflecting the snow as it passes from the chute so that it will enter the outermost spout.

3. A snow remover including a casing having an aperture adapted to be fed against the snow, an inclined chute leading from said casing, means for forcing snow through said casin and chute, delivery spouts pivotally connected to said chute and adapted to swing horizontally, means for swinging said spouts, means for deflecting the snow as it passes from the chute so that it will enter the outermost spout, and means for holding said spouts in adjusted position.

A snow remover including a casing having an aperture adapted to be fed against the snow, an inclined chute leading from said casing, means for forcing snow through said casin and chute, delivery spouts pivotally connected to said chute and adapted to swing horizontally, means for swinging said spouts, means for deflecting the snow as it passes from the chute so that it will enter the outermost spout, and side plates hinged to the spouts and slidably connected to the casing.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
