SNOW REMO'VER.
Application filed May 8, 1923. Serial No. 836,480.
Snow Removers, of which the following is a specification.
The present invention relates to machines for removing snow from roadways, and more particularly to machines of this character which employ rotary fan ploughs for V excavating the snow and then discharging it by centrifugal action to the side of the roadway or into a suitable vehicle to be conveyed to a dumping ground.
The objects of this invention are, to provide a rotary snow remover which is adapted to be mounted on the chassis of a motor vehicle and to be removed therefrom when not in useto 1provide a snow remover having a fan ploug of improved construction, enabling the apparatus to be readily driven through deep snow; and to provide an apparatus of this characterin which the motive power of the plough'is independent of the power plant for propelling the vehicle on which the apparatus is mounted, thus making it feasable to employ the apparatus in connection with trucks of relatively low power.
Referring to the accompanying drawings for a particular description of an embodiment of the present invention:
Figure 1 1s a side elevational view, with parts broken awa of a motor truck havmg my improve snow remover applied thereto.
Figure 2 is a front elevational view.
Figure 3 is a detail view, showing in cross section apart of the fan-plough casing and one of the fan blades. I
The drawings show the snow remover mounted on the chassis of a Ford truck. The numeral 10 designates the engine which propels the truck and the numeral 11 designates the propeller shaft, The truck, of
course, is provided with the usual steering wheel 10 and the usual foot and hand levers for controllin the engine drive.
The apparatus embodying the present invention is mounted on an elongated rectangular frame 12 which is detachably sup- :ported on the chassis of the truck in any approved fashion. Preferably, this frame is provided with a housingl 13 which is secured thereto by the uprig ts 14 and which completely encloses a drivers seat 15, for
the purpose of protecting the driven from exposure. Secured to the forward end of the frame is a pair of volute housings or casings 16, which have front circular openings 17 and which are formed with tanential discharge portions or pipes 18. lurved pipe sections 19 are fitted to the upper ends of these discharge portions, for the purpose of directing the snow, which is forced and blown through the discharge pipes, laterally or to the side of the roadway where it will not impede trafiic. Pipes 19 are'preferably made detachable so that they may be turned through an angle of 180, thereby adapting the apparatus to discharge snow at either side of the roadway or partly on both sides.
. Mounted in each of the housings 16 is a. rotary fan-plough which, in the illustration, consists of four blades 20 secured to a circular disk 21, which has a hub 22 keyed on. a drive shaft 23. Each of the blades 20 has a flange 24 riveted to disk 21, an intermediate portion at right angles to disk 21, and a cutting edge 25 which extends at an acute angle to the plane of rotation and in the direction of rotation. Attention is particularly called to the fact that the cutting edges 25 extend substantially beyond the outer periphery of casing 16. These cutting edges, therefore, will excavate a path through the snow of substantiall greater diameter than the diameter of tie casing and will therefore facilitate the movement of said casing as it is forced through the snow by the propulsion of the truck.
I preferably employ an individual motor 7 for each of my fan-ploughs. The motors for driving said ploughs are designated on the drawings by the numeral 26. These motors are mounted in any suitable manner at the sides of frame 12 adjacent the rear end thereof and have a driving connection with theaforementioned shafts 23. The shafts 23 may extend above or below the cros members of frame 12, as required by particular power'plant conditions. By employing a separate individual motor for each of my fan-ploughs, I am enabled to provide a.
regard to the power of the truck on which the remover is mounted, and furthermore obtain a direct drive from an individual motor to each plough, whereby each plough may with facility be independently operated snow remover of any desired power without at the speeds required by the condition of the roadway.
Having particularly described an apparatus embodying my invention, what I claim as new and desire to secure by Letters Patent of the United States is;
1. An apparatus for removing snow from roadways, comprising a truck having a propulsion power plant, a frame mounted on the chassis of said truck, a pair of housings having open front ends secured to the forward end of said frame, said housin s having discharge pipes extending upwardly and tangentially therefrom and having laterally curved extensions, :1 motor mounted on each side of said frame adjacent the rear end thereof, a shaft driven by each of said motors projecting forwardly therefrom into said housings, a plurality of blades in each of said housings secured to said shafts ra dially thereof, each of said blades having a cutting edge inclined in the direction of rotation, said cutting edges extending in front, of said housings and beyond the outer peripheries thereof.
2. An apparatus for removing snow from roadways, comprising a truck having a pro pulsion power plant, a frame mounted on the chassis of said truck, a pair of volute housings havin circular front openings secured to the forward end of said' frame, said housings having discharge pipes extending tangentially therefrom, a pair of motors mounted on said frame, a shaft driven by each of said motors projecting forwardly therefrom into said housings, a plurality of blades in each of said housings secured to said shaft radially thereof, each of said blades comprising a body portion substantially perpendicular to the plane of rotation and a portion inclined in the direction of rotation terminating in a cutting edge, the inclined portions of said blades extending forwardly beyond said housings and radiall beyond the outer peripheries thereof? 3, An apparatus for removing snow from roadways, comprising in combination with a motor vehicle, a volute casing mounted at the forward end of said vehicle having a circular front opening and a tangential discharge conduit, a driving shaft extending centrally into said casing, a plurality of blades-in said casing secured to said shaft radially thereof, each of said blades comprising a body portion substantially perpendicular to the plane of rotation and a portion inclined to the direction of rotation terminating in a cutting edge, the inclined portions of said blades extending forwardly.
ing, a motor mounted on said frame having 4 a driving connection with said shaft, a circular disk in said casing secured centrally to said shaft, a lurality of blades attached to said disk radially of said shaft, each of said blades comprising a body portion substantially perpendicular to said disk and a portion inclined in the direction of rotation terminating in a cutting edge, said inclined portions extending forwardly beyond said casing and radially beyond the outer periphery thereof.
5. In an apparatus for removing snow from roadways, a frame adapted to be mounted on the chassis of a motor vehicle, a casing mounted atthe forward end of said frame having a circular front opening and a laterally directed discharge conduit, a driving shaft extending centrally into said casing, a motor mounted on said frame having a driving connection with said shaft, a circular disk in said casing secured centrally to said shaft, a plurality of blades attached to said disk radially of said shaft, each of said blades comprising a flange riveted to the outer face of said disk, a body portion substantially perpendicular to said disk, and a portion inclined in the directionof rotation terminating in a cutting edge, said in clinecl portions extending forwardly beyond said casing and radially beyond the outer periphery thereof.
6. In an apparatus for removing snow from roadways, a frame adapted to be mounted on the chassis of a motor vehicle, a casing mounted at the forward end of said frame having a circular front opening'and a laterally directed discharge conduit, a
driving shaft extending centrally into said casing, a plurality of blades in said casing attached to said shaft radially thereof, each of said blades comprising a portion inclined in the direction of rotation and terminating in a cutting edge, said inclined portions extending. forwardl beyond said casing and radially beyond t 1e outer periphery thereof. In testimony whereof I hereunto aflix my signature.
