6 Claims.
Thi invention relates to snowplows and more particularly to motor driven snowplows such as are specifically adapted for use in removing snow from sidewalks, driveways, and the like.
An object of the invention is to provide a snowplow which may be easily handled and which Will operate to move the snow to the side of a path being cleared.
A further object of the invention is to provide a snowplow which is so constructed that it will permit movement of the snow in a lateral direction and in such a manner that the snow will be packed into the side of the path being cleared, as the plow is moved along said path to thereby provide for the accommodation of a greater amount of snow and prevent the removed snow from falling back upon the cleared path.
A further object of the invention is to provide such a snowplow which is motor driven and which may be detachably connected to a power device, such as a hand tractor or the like.
Further objects and advantages of this invention will be more clearly understood from the following description and from the accompanying drawings, in which- Fig. 1 is a perspective view showing the snowplow of my invention and a hand tractor to which said plow is attached.
Fig. 2 is a front view of said plow in central vertical section.
Fig. 3 is a side view thereof in central vertical section.
Fig. 4 is a plan view of said plow.
Fig. 5 is an end view, partially broken away to show the driving mechanism.
As illustrated in the drawings, the numeral 5 denotes a conventional hand tractor, such as commonly used and mounted on a pair of wheels 6 which are driven by a suitable motor I to propel devices attached to said tractor. The tractor is controlled by means of handles 8 to which are conveniently located hand operated levers 9i0 for controlling the speed of the engine and also the clutch by which said engine is connected to the wheel 6.
My improved snowplow is attached to the said tractor and driven thereby and, in the embodiment shown, the said plow comprises a back plate I i mounted on suitable brace bars 12-! 2 to which are connected brackets I3l 3 by means of which the said plow is fastened to the tractor 5 by suitable fastening members, not shown.
Attached to the back plate H is a supporting frame consisting of a supporting hoop 14 at one 2 hoop l5 at the opposite side. These hoops are connected by a tie bar I 6 running along the front of the plow.
The hoop It has a plurality of spokes ll which support a suitable bearing l8 and a separate bearing I9 is provided at the opposite side of the plow in a housing I9a which is connected to the back plate H.
A screw 20, preferably in the form of a helical blade extending around a tubular member 2|, is supported by suitable bearings 2Z22 and secured to a shaft 23 which is journaled in the bearings The said shaft 23 has mounted thereon a sprocket 24 which is driven through a chain 25 by means of a sprocket 26 on a drive shaft 21 that is driven by the motor I.
At each end of the back plate I l and extending rearwardly from the hoops I l-I5, there is provided a pair of side plates, or shields, 2828 which extend to a point rearwardly of the front of each of the wheels 8 of the tractor so as to shield the said Wheels from any loose snow which would otherwise fall in front of the wheels and interfere with the traction thereof.
My improved plow is also provided with an auxiliary plow 29 which preferably includes a pair of deflector blades 3030 that diverge rear- Wardly towards the sides of the plow and extend upwardly from and along the leading edge of the back plate which extends over the top of the screw 28.
In the operation of my improved plow, the screw 20 is rotated in the direction of the arrow shown in Fig. 3 as the said plow is driven forwardly by the tractor 5. Rotation of said screw will move the snow endwise along the screw and force it to one side, through the supporting ring as, with sufficient force to pack the snow into the side of the path being cleaned.
The said plow will accommodate snow up to a height equal to the top of the back plate ll. Any snow above that height will be deflected sideways to both sides of the plow so that it will be deflected away from the engine I and fall on the surface of the path from which it will be picked up on the next trip of the plow.
In order to support the plow at a predetermined distance above the surface being cleaned, there is provided a pair of shoes 3l3l below the sup-' porting rings i l-l5. These shoes will support the plow so that the bottom of the scraper bar 32, which is provided at the lower edge of the back plate ll, will be maintained at a slight distance side of the back plate and a separate supporting above the said surface.
It has been found, by actual use, that my improved plow is highly efficient in its operation, easy to use, and that it will remove snow to a height extending even above the top of the screw 29. It has also been found that the forwardly projecting portion Ila of the back plate II will guide the snow downwardly into the screw 20 and thereby increase the efficiency of'the machine in clearing snow of asubstantial depth.
The side plates 2828 will aid in smoothing the snow against the side of the path and also prevent it from accumulating in back of the plow and in front of the trailing tractor as the plow is moved forwardly through the snow.
I claim:
1. A snowplow of the character described comprising a frame including a pair of hoops located at opposite sides of said frame, bearing means co-axial with said hoops, a screw rotatably mounted in said bearing means, means for driving i said screwya back plate extending around a portion of the rear of said hoops and having a-leading edge projecting forwardly over the tops of the hoops, and an auxiliary plow including a pair of diverging blades mounted upon said forwardly "projecting portion of the back plate and extending rearwardly and upwardly from and along the leading edge of said back plate whereby the rotat- .ably'driven screw is capable of moving snow transversely along said back plate and force said snow through one of said hoops, and said auxiliary plow deflects snow above the height of the back plate.
