a full, clear, and exactspecification, which will enable others skilled in the art to which it a pertains to make and use the same.

y invention relates generally to improvements in snow plows; and it consists, essentially, in the novel and peculiar combination of arts and details of construction, as heremafter first fully, set forth and described and then pointed out in the claims.

The object of this invention is the production of an efiicient and serviceable snow plow, whichthough applicable to general use, is especially designed for country roads. In order to accomplish this object, I constructthis snow plow, in the preferred embodiment of my invention, as shown in the drawings, in which- Figure 1 is a side elevation of my snow plow as it appears when in actual use. Fig. 2 is a plan of the same. Fig. 3 is a plan of the sled and a part of the pushing device by which the sled is propelled and steered. Fig. 4 is a rear elevation of the snow plow roper, details of construction of the pushing mechanism being omitted. Fig. 5 is an elevation, partly in section, of mechanism for raising and lowering the rear end of the movable platform to change the inclination thereof. Fig. 6 is an elevation of this device as it appears when turned through an; angle of 90 degrees. Fig."- 7 is a plan of part of the pushing and steering mechanism detached. Figs. 8, 9, and 10, are further details in perspective, of this device.

Like parts are designated by the same characters and symbols of reference in all the various figures.

This snow plow' comprises two mainstructures', viz. the snow plow proper A, and a sulky B, by which latter, and horses C, hitchedthereto, the snow plow is propelled by pushing the same ahead.

The snow plow proper is comprised of a frame structure conslsting, preferably, of

v a pair of substantial runners 12, 13, which are connected by a series of transverse bars or rails 14, 15, 16.

, U on this frame structure, which is, referab y, constructed of wood, there is a xed -a platform D, which inclines upwardly and rearwardl at an angle of degrees, more or less. t traverses the frame structure and extends beyond the rear end thereof for some distance. Upon this fixed platform there is located a second latform E, of the same width as the fixed p atform, but somewhat shorter than the latter. This second platform, which I shall hereinafter term the movable platform, is hinged or pivotally connected to the fixed platform at its forward end, a slight distance from the forward end of the fixed platform; strap hinges 17, or analogous means being employed for this purpose. The rearv end of this movable platform E is supported by an elevating device F, of any approved design, an example of such a device being best shown in Figs. 5 and 6. It comprises, preferably, a rotatable screw 18, rovided at its upper end with a hand whee or other suitable means 19, which by a ball and socket joint 20, at the lower end of the screw, permits of the screw being rotated and rocked to adapt itself to different positions it may have to assume when rotated to raise or lower the movable platform.

Upon this screw 18 there is mounted a nut 21, which nut has trunnions 22, oscillatably mounted in bearings 23, fixed to the deflect snow rising on the movable platform I 1, 2, and 4, jointed together angularly at v,mold board of a the apex 26, to serve similar in action to a low, to elevate the snow and throw it off t e movableplatform. To

the sides of the movable platform are hinged fenders 28, 29, preferably strap hinges 30. These fenders are PI'OVI ed with means for ehan g their an larity with reference to thi movable p atform, an example of such means being illustrated in Fig. 4.

' A strap 31, on each fender, is pivotally connected to the fender at 32, which strap has a series of notches 33, to engage a pm 34. This pin is placed into a U-shaped support 35, rising from the runners 12, 13, and supportin the fixed platform D near its rear,

end. y changing the notches in the straps 31, the fenders may be angularly-adjusted to throw the snow descendin from the defiectorsfarther away from t e runners, or dropping it nearer thereto, as the case may I re uire, in an obvious manner.

purpose of pushing and steering the plow,

ll employ peculiarly constructed mechanism,

comprising a bar 38, located medially between the runners 1-2, 13, upon the cross rails 15, 16. This bar abuts .Wlth. one end against a stop 39, Figs. 3 and 4, comprising,

desired, an iron angle bar; and this end of said bar 38 is, preferably cylindrical, as indicated at 42, Fig. 7 and provided with a hole 40, in which there is a substantial pin 41, passing through the rail'15; the. hole 40 being, preferably, oblong, as shown, the ob- 'ect of which will further on appear. This ar 38 extends some distance beyond the rail 16, and it has-near its outer end a further journal 42, embraced by a U-shaped strap 43, Figs. 3 and 4, secured upon the rail 16. This journal 42 is transversely slotted at 44, Fig. 7, to receive a pin 45, passing through the slot, the strap and the rail 16, as illustrated in Fig. 4.

. At the sides of the bar 38 there are straps 46, best shown in Figs. 7 to 10 inclusive, a pivot bolt 47 passing through these straps near the end of the bar 38, which end is, preferably, horizontally rounded ofi as indicated in Fig. 8 at 49. To these straps is bolted a short extension 38, of the bar 38, and the outer end of this extension is vertically rounded OK, as shown at 49*, in Figs. 9 and 10.

The reach 51, of the sulky B extends forwardly and abuts against the rounded end 49 of the extension 33*, and connects with naeaeer the latter b two straps 50, placed onthe upper and ower surfaces of the extension 38 and the forward end of the reach 51;

"ah handle bar. I, the forward end of which engages the bolt 54, and the rear end of which reaches to within a convenient distance of the operator standing on the foot board 37.

The operation of this pushing and steer.- in mechanism is substantially as follows:

he horses being properly hitched to the sulky and moving forward, causes the reach of t e sulky to push against the extension 38, and this, in turn, pushes against the push-bar 38, and by it, move the' snow plow orwardly into the snow in front of/ the plow. This snow ascends the forward portion of the fixed platform (which has sharpedges) and is de ected therefrom by the deflector and discharged from thefenders, as already described. When it is desired to make a turn in the road, the operator moves the handle bar 51 in the proper direction. This handle bar is a long lever having its fulcrum in the pivot bolt 56, and its short arm connected to the push bar 38 by the bolt 54. It follows that by this movement of the handle bar the rear end of the plow is deflected from a straight course, which movement the sulky will follow until the handle bar is again brought in normal position or alinement with the reach 51. And in order that this reach 51 and the push bar 38 may readily assume this angular position,'the end of the extension 38, or the forward end of the reach (or both) is rounded off at 49.

In operating this snow plow over undulatory ground a condition may arise wherein the sulky and the plow may not be in the same horizontal plane which would cause torsional stress in the reach or in the push bar 38. To avoid this objectional feature, ll

have provided the push bar 38 with the.

journals 42, 42, so that either the plow or the sulky may rotate or rock; and to permit this rocking movement, the slots in the journals are provided for the reception of the pins 42 and 45. These pins, while not essential when the plow is being pushed, are, nevertheless, necessary when the plow is backed up and} the push rod 38 pulls on these pins. And in-order that the snow plow may readily rise or fall to follow undulations of the ground over which the machine is being moved, ll have provided the aaeaeer ends of thereach 51- and the extension 38 with a positively functioning connection, by supplying these ends with castings having segments of cog wheels 57, as shownin Fig. 7, whereby the angular movement of the reach and the push 'bar is greatly facilitated.

I may here state that while metal may be largely employed inthe construction of this snow plow, I'prefer to construct the principal parts thereof of wood, it being a wellknown fact that snow will readily adhere to metal when the latter is cold, and thereby prevent rapid and efficient movement of the snow on the platforms, the deflectors, and

It is also desirable that when the fenders. an ice-crust has formed on the snow to be moved, this crust be broken; and for this purpose I mount on the forward ends of the runners vertically disposed knives 60, which will accomplish the desired function in a satisfactory manner. On country roads which. have been covered with snow on which there has been more or less traffic, so that the snow is packed and grooved or guttered bythe runners of sleighs or by vehicle wheels and then more snow has fallen whichit is necessary to remove to preserve this thin, hard packedlayer so that trafiic with sleighs may be carried on, I have provided the snow plow with a pair of auxiliary runners 61, 62, spaced apart the usual spur width of a farm wagon or sleigh, which is also the distance of the grooves or tracks in the snow. These two auxiliary runners are somewhat less in depth than the runners 12, 13, and when running in the guttered tracks prevent the snow plow from sinking deeper into the snow than desired, thereby preserving a sufficiently deep snow-bed on the road to render trafiic with sleighs, sleds, and cutters easily feasible, which would not be the case were all the snow on the road removed by the plow. It will thus be noted that this snow plow is not necessarily designed to completely remove snow from streets or roads, but rather to leave thereon a layer of snow on which traffic with road vehicles is possible.

I have hereinbefore stated that the snow plow is propelled by a team of horses, but it is evident that the propelling power may be other than animal power, such as traction engines, and the like.

I have hereinbefore described the preferred embodiment of my invention with considerable minuteness; but I desire it to be distinctly understood that I am aware that changes in the details of construction disclosed may be made, and parts omitted without departing from the sco e of my inventi n as defined in the subjomedclaims.
