3,002,298 SNOW PLOW Russell B. Baldwin, Rahway, NJ. (60 McCoy Ave, Metuchen, NJ.) Filed July 24, 1959, Ser. No. 829,390 3 Claims. (Cl. 37-45) The present invention relates to a snow plow generally, and specifically to a hand propelled snow plow.

Previously proposed and presently in use are snow plows of the hand propelled type which have scoop bodies intended to receive a load of snow when the plow is pushed over a ground surface, such plows having storage means for the gathered snow for transporting the same to a place of disposal. The plows proposed and in use are not really successful for many reasons. Principally, when cleaning a sidewalk or driveway of snow, an individual desires merely to move the snow to one side of the sidewalk or driveway and does not require the total removal of the snow from the area to a place of disposal. Such snow plows having means for storing a quantity of snow temporarily until removal to a place of disposal are awkward to handle, consume excessive labor and time in the removal of the snow to the disposal area, and are therefore inefficient in operation. Other snow plows proposed and in use are satisfactory for a single use in clearing a sidewalk, for instance, of a quantity of snow. A second or later use of the snow plow, after the sidewalk has been cleared, is ineffective for the reason that such a plow merely pushes to one side the snow and the already compacted snow at the sides of the sidewalk prevents efficient removal of the snowand piling thereof along the sidewalk.

An object of the present invention is to provide a hand actuable snow plow having means for elevating and casting to one side snow removed from a ground surface.

Another object of the present invention is to provide a snow plow, of the hand actuable type, and one which is moved with ease and facility over a ground surface scooping up light or compacted snow and disposing of such snow in a row along the path of movement of the snow plow.

A further object of the present invention is to provide a snow plow which is sturdy in construction, one having a minimum of moving parts easily replaced and easily reassembled, one which ishighly efiective in action, and one which is economically feasible.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in conjunction with the annexed drawings, in which:

FIGURE 1 is a plan view of the snow plow according to the present invention, upper end portions of the handle not being shown;

FIGURE 2 is a side elevational view, portions of the handle being broken away;

FIGURE 3 is a view taken on the line 3--'3 of FIG- URE l; and

FIGURE 4 is a rear elevational view, the upper end portions of the handle being omitted.

Referring in greater detail to the drawings in which like numerals indicate like parts throughout the several views, the snow plow of the present invention comprises a scoop body having a forward end 12 and a rearward end 1-4.

The scoop body 10 is formed from a pair of laterally spaced

upstanding walls

16 and 18, the wall 18 extending from the forward end 12 to and about the rearward end 14, as shown in FIGURE 1, and the wall 16 extending from the forward end to a point adjacent to and spaced from the rearward end 14, as also shown in FIGURE 1.

Patented Get. 3., 1961 The space between the terminating point of the Wall 16 and the rearward end 14 forming a discharge means or opening 20, FIGURE 1.

An upwardly sloping apron 22, adapted to roll snow into the scoop body 10, projects from the forward end 12 of the scoop body.

A pair of

side members

24 and 26 extend longitudinally of the scoop body 10 below the same and extend from the rearward end of the apron 22 to a point forwardly of and spaced from the portion of the wall 18 adjacent the discharge means 20. An axle 28 extends between the

side members

24 and 26 and has its ends fixedly secured in

theside members

24 and 26, as shown most clearly in FIGURE 4.

Freely rotatable on the axle 28 are ground-

engaging wheels

30 and 32 inwardly of and adjacent the

side members

24 and 26, respectively.

An endless belt conveyor 34 is rotatable about spaced

rollers

36 and 38, constituting horizontal axes, and has its upper flight 40 positioned between the lower ends of the

walls

16 and 18 and has its lower flight 42 below and adjacent to the lower ends of the

walls

16 and 18.

The roller 36 is journaled on a shaft 44 which has its ends secured to the forward ends of the

side members

24 and 26. The roller 38 is journaled on the shaft 46 which has its ends supported in

upper side members

48 and 50 which extends along the lower ends of the

walls

16 and 18, respectively, and form supports for the

walls

16 and 18.

A back member 52 (FIGURE 4) extends between the rearward ends of the

upper side members

48 and 50 and connects the latter together, the

upper side members

48 and 50 having their front ends connected to the forward ends of the

side members

24 and 26, respectively, and also to the lower ends of

bars

54 and 56 which extend rearwardly and upwardly and carry on their upper ends a handle 58.

Brace

members

60 and 62 extend upwardly from the midportions of the

side members

24 and 26 and have their upper ends secured to the underfaces of the

bars

54 and 56, as shown in FIGURES 2 and 3.

Cooperating means is provided on the

wheels

30 and 32 and on the lower flight '42 of the conveyor 34 drivingly connecting the

wheels

30 and 32 to the conveyor 34. Specifically, this means consists in a plurality of angularly arranged ridges 64 on the exterior face of the conveyor 34, the ridges 64 being arranged in spaced relation thereabout. The means also includes a plurality of spaced grooves 66 on the periphery of the

wheels

30 and 32, the grooves 66 being conformably shaped to and receivably engaging the ridges 64 on the lower flight 42 of the conveyor 34 for drivingly connecting the

wheels

30 and 32 to the conveyor 34.

The angular disposition of the ridges 64 on the upper flight 40 of the conveyor 34- serves to deliver to the discharge opening or means 20 in the wall 16 snow received from the apron 22 when the conveyor 34 rotates on its

rollers

36 and 38.

In use, the snow plow of the present invention is employed to remove snow from a ground surface such as a sidewalk, driveway, or the like. Upon forward movement of the scoop body responsive to pushing eflort applied to the handle 58, snow will enter the scoop body 10 over the apron 22 and will be transported by the upper flight 40 of the conveyor 34 to the discharge means 20 in the wall 16 of the scoop body 10. The forward movement of the scoop body 10 over the ground surface rotates the

wheels

30 and 32 in the clockwise direction and the wheel 32 drives the conveyor 34 in the counterclockwise direction, as shown in FIGURE 3, so as to convey the snow from the apron 22 upwardly through the scoop body to the curved portion of the wall 18 which, together with the angular disposition of the ridges 64 on the upper flight 40, delivers the snow to the opening in the side wall 16 for delivery along the path or driveway over which the snow plow is manually propelled.
