GUTTER SNOW-PLOW.

Application filed February 26, 1915.

To all whom it may concern:

Be it known that I, WARREN F. WHEELER, a citizen of the United States, and resident of Stoneham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Gutter Snow-Flows, of which the following is a specification.

This invention relates to plows adapted to work beside a sidewalk curb and force snow outwardly therefrom to clear the gutter beside the curb.

The invention has for its object to provide an effective gutter plow adapted to be adjusted to meet various requirements, and of strong and durable construction.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification: Figure 1 represents a side view of a snow plow embodying my invention, the scraper hereinafter referred to being raised; Fig. 2 represents a view similar to a portion of Fig. 1, showing the scraper lowered; Fig. 3 represents a section on line 3-8 of Fig. 1; Fig. 1 represents a section on line 44 of Fig. 1; Fig. 5 represents a section on line 55 of Fig. 2, and a front elevation of parts at the left of said line.

The same reference characters indicate the same or similar parts in all the views.

My improved snow plow comprises a frame which includes an inner runner 12, an outer runner 13, and a superstructure extending above the runners, the whole forming a rigid frame capable of being drawn by a horse, and supporting the movable parts hereinafter described.

Since the construction of the superstructure may be variously modified it need not be described in detail further than by stat ing that it preferably includes front and

rear uprights

14, 15, at opposite ends of the outer runner, and formed of metal integral with said runner, horizontal frame members including a longitudinal member 16 bolted to the upper ends of said uprights, transverse members 16 connecting the member 16 to a similar longitudinal member,

not shown, at the opposite side of theframe,

uprights 16 bolted to the inner runner, and other suitably arranged and connected members required for the strength and rigidity of the frame as a whole.

17 represents a vertically movable scraper, which has an oblique front face curved outwardly from its upper to its lower edge, the latter being substantially horizontal. The scraper is obliquely arranged, as shown by Fig. 3, and its forward end extends across the path of the inner runner 12 in advance of the forward end of said runner,-the rear end of the scraper being between the two runners.

The scraper is formed and arranged to move snow obliquely from the path of the inner runner 12 toward the outer runner 18. The forward end of the scraper has a vertical edge 1'7 (Fig. 5) adapted to move in close proximity to the face of a curb at the inner edge of a gutter. The length of the scraper is preferably considerably less than the distance between the runners, so that the snow displayed by the scraper may accumulate between the runners, although, as hereinafter described, provision is made for the escape of a part of the displaced snow outwardly across the outer runner.

I have provided means for varying the height of the scraper, so that its lower edge may work as closely as may be desired to the surface of the gutter. Included in said means is a vertical hanger or connecting rod 19 pivoted at 20 to an ear 21 on the central portion of theupper edge of the scraper, and at 22 to a lever 23 which is fulcrumed at 24 to a fixed upright 26 on the frame, said lever being adapted to swing in a vertical plane and thus raise or lower the scraper 17, through the hanger 19. The lever 23 may be locked in various vertical adjustments by a locking dog 28 carried by the lever and a fixed segmental arm 29 having notches to engage said dog. The arrangement is such that the lower edge of the scraper may be forced below the level of the runners, as shown by Fig. 2, so that the entire forward portion of the structure is slightly lifted and its weight is exerted on the scraper.

60 leveler, is pivoted at 38 to a fixed standard The hanger or rod 19 and lever 23 constitute a simple and effective means for vertically adjusting the scraper and causing it to raise the forward portion of theframe, if desired, but do not prevent horizontal displacement and oscillatory movements of the scraper. I have therefore provided for this purpose scraper-bracing means conforming to vertical movements of the scraper and preventlng oscillatory movements and hori- 'zontal displacement thereof. I have embodied said means in a pair of longitudinally extending

struts

31,32, pivoted at their rear ends upon a transverse pin 33, which is supported by the inner runner 12 and by abracket 34; attached thereto behind the scraper. The forward ends of said struts are suitably connected as by bolts 35 to the scraper 17, the inner strut 32, which is at the outer side of the runner 12, being con- ,nected to the forward end of the scraper,

while the outer strut 31, which is offset inwardly from the runner 12, is connected to the central portion of the scraper.

The struts swing in vertical planes, and while they conform to' vertical adjustments of the scraper, they prevent it from swinging and from being displaced horizontally. V The movements of the struts are practically unopposed by friction, so that the struts perform their function without impeding or reto'form, in a gutter, a path or trench that is much-,-narrower than the. space between the "just-outside the inner runner and close to a two runners, one margin of said path being sidewalk curb, and the other margin being between the runners. By thus narrowing the path formed by the scraper the action of the scraperis so concentratedthat the plow is enabled to effectively remove hard snowand slush from a gutter close toa side- Walk curb, and leave the removed material between the runners and separated from the curb. The. runners are-sufliciently spaced apart to afiord a wide runner base, and prevent the plow from being top heavy.

.37 represents a bar adapted to smoothen or flatten aridge of snow left by the scraper 117. Said bar, which is technically called a 39 on the frame at a point adjacent to and behind the scraper, and extends. obliquely in a direction parallel with the scraper through the above-mentioned opening and across the outer runner 13, as indicated by Fig. 5, the outer portion of the leveler bearing on the rear upright 15. Said upright therefore serves to back the leveler and pre vent its rearward displacement.

The leveler 37 is adapted to swing in a vertical plane, and is adjustably supported by a hanger all pivoted at 42 to the leveler, and a lever 43 fulcrumed at 44 on a fixed upright 45 and pivoted at 4:6 to the hanger 4:1.

The lever 43 swings in a vertical plane and may be locked at different adjustments by a dog 47 and a fixed notched segment 48. The

adjustment of the leveler will depend on the height of the ridge of snow left by the scraper.

The leveler may be a stout wooden bar provided with a wear plate 37 (Fig. 4) in sliding contact with the upright 15.

Having described my invention, I claim:
