T at whom it may concern.-

Be it known that LWARREN F. WHEELER,

0f Stoneham, in the county-of Middlesex My invention relates to snow plows forclearing snow from the sidewalks of streets in the appended claims.

and highways; and consists in a'plow em-v bodying the novelties in construction, arrangement and mode of operation which are hereinafter fully described and pointed out Figure 1. is a perspective view of the plow as seen from a point on the left of the'plow.

Fig. 2. is a perspective view as seen from a point on the right of the plow. Fig. 3. is a longitudinal section taken as on line 17, a, Fig. 1, and showing in dotted lines the position of the plow when raised and supported on runners A and A. Fig. 4. is a transverse section taken as on line 2, Fig. 1, and viewed from the left of said line. Fig. 5. is a rear elevation.

Referring to Fig. 1, the general construction of the plow will be seen to consist, in part, of two sleds, A and B, an inner and an outer one, the runners on the right side of the sleds being only about half the length of the runners on the left side. and A of the inner sled are pivoted at their rear ends to the corresponding ends of the outer runners B and B, by bolts Oand O and are shodwith metal. Runner B extends nearly the entire length of the plow and at its forward end is incased in an inclined iron share D, which rests on a twisted iron shoe D that forms a brace betweenthe share D and an overhanging beam E, and also extends along the bottom of the runner B to the rear end thereof. Upon the forward end of runner B is constructed the side F of the plow,

. framed and planked in a substantial manner and forming at its curved front edge an acute angle with the opposite side F with which it is there'united. Side F is in line with run- 56 ner B while said opposite side is oblique The runners A thereto and its outer wall or face is concaved.

Referring now to the opposite side, shown in Fig. 2, there will be clearly seen the substantially framed and planked side F joined at the front with side F and supported on the same shoe D to which they converge, and also upheld by a floor plank F (shown in Figs. 1 and 3 but omitted in Fig. 2 to avoid confusion of lines) extending diagonally from 'a cleat on and near the top of the front end of runner B, to the top of-the front end of runner B The lower edge of side F, which overhangs and extends'below the runners on its side of the plow, is provided on the outer face with an iron scraper F which comes in contact with the surface of the sidewalk when in practical operation. A draw-bar G is strongly bolted to beam E, and provided with suitable irons for attaching thereto the shafts by which the plow is drawn, as shown, and is also stayed by an iron rod H which is bolted at its front end to draw-bar G, and thence extends through side F and is bent downward and bolted to runner B, as indicated by dotted lines. Runners A and B are made shorter than runners A and B to accommodate them to the oblique side F, which crosses their paths. To the rear end of side F is hinged a wing extension I, as shown in Fig. 1, which has a movement on its hinges so that it may be swung outwardly into line with side 4 scribed are normally wholly supported upon runners B and B. These runners have crossbeams, or planks, J and J bolted at one end to the top of runner B and the other end to cleats secured to the inner face of runner B, as clearly shown in Fig. 2, runner B being higher than runner B- as well as longer.

A plank floor K is laid openly across the tops of runners A and A upon which the operator of the plow stands when it is in practical use; and an oblique plank K is bolted at one end to the top of the forward endof runner A, and at the other end to-the top of the forward end of runner A, thus firmly connecting the two runners at their forward ends.

In practical use, besides propelling and guiding it, there are two operations of the plow, namely, raising and lowering it, and swinging the Wing scraper I in and out as may be required. These two operations are accomplished by the means and in the manner which I will now describe. When the plow is raised to clear its scrapers from the sidewalk, or highway over which it is simply passing, it is then wholly supported upon the auxiliary runners A and A pivoted to runners B and B, as described. To thus raise the plow there are provided two levers L and M. The long lever L is pivoted to the lower end of a block L bolted to the inner wall of the side F. A short distance back from the pivot block L of lever L, and near runner B, is secured a fulcrum block L resting on plank K which connects the forward ends of the inner runners A and A. Over this fulcrum lever L is arranged to pry in raising the plow. The transverse lever M, the free end of which crosses the path of the free end of lever L, is pivoted to a block M, bolted to the inner wall of side F, and is arranged to pry over a fulcrum block M also resting on plank K near runner B.

To raise the plow the operator depresses the free end of lever L, which in its passage downward comes in contact with the free end of lever M, which crosses its path as before stated, and carries it down also, thus lifting simultaneously upon both sides of the plow. Upon one of the upright posts of the crossframe which connects the sides of the plow is bolted an iron ratchet bar N, with which a ratch-plate N, on lever M, engages as the lever is moved down, and by such engagement with the teeth thereon the plow-may be thereby suspended at various heights as required, supported on runners A and A, through plank K and the pivotal connections described. When the plow is thus raised to carry it over curbstones or uneven surfaces, in order to keep the forward ends of runners A and A within proper limits of separation therefrom, and so that they will follow readily, they are loosely chained to hooks attached to the interior walls of the sides F and F, as clearly shown in Figs. 3 and 5. Thus the plow may be raised and lowered at will, while in practical operation, and may be held suspended at a suitable elevation to clear its scrapers from the surface while it is transported from place to place on said auxiliary runners. To swing wing I into any desired position a vertical rod P is employed, having upon its top a crank P by which it is turned, and being seated at its lower end in a hole in a block J 2 bolted to plank J, and also steadied by a brace P through which it passes, secured to the cross-beam P of the plow frame. Coiled about the lower end of rod P is a rope It secured at one end to the rod and at the other end to a horizontal bar R hinged to runner B and jointed to another horizontal bar R which is hinged to wing I, as clearly shown in Fig. 1. The end of bar R which is jointed to bar R rests upon a wearing board or plate R secured across the floor planks as shown, and moves back and forth thereon in its practical operations. By turning crank P and thereby coiling the rope R around rod P, the jointed ends of bars R and It willbe drawn toward rod P thus increasing the distance between the two outer ends of said bars, and consequently forcing wing I to swlng outward, accordingly as such compound hinge is thus caused to open. And the wlng will be held so spread outward as long as the rope is so drawn upon; but if the tension on the rope is relaxed by turning the crank P in the opposite direction, then the wing wlllbe closed, to the extent the rope is slackened, by the frictional contact of its scraper with the surface of the sidewalk, or with the snow or other obstructions thereon.

4:. A snow-plowcomprising a body composed of parts F and F and Wing I, mounted upon a sled B and provided with overhanging scrapers F and I; an auxiliary sled A arranged beneath and connected with sled B to support the plow and uppersled when raised from the ground; and means .for raising the plow from the ground and securing it in such position; all substantially as and for the purposes specified.
