UNITED STATES PATENT OEETcEc ROBERT B. NEVENS, OF LOWELL, MASSACHUSETTS.

IMPROVED sNow-PLow.

Specification forming part of Letters Patent No. 58,1211, dated September 18, 18663.

To all whom t may concern:

Be it known that I, ROBERT B'. NEvENs, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Snow-Blows, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, makin g part of this specification, in whichi Figure l is a plan or top view; Fig. 2, a side elevation, and Fig. 3 a transverse section.

'I construct my improved snow-plow in the form ot" a triangle, the longest side of which is generally one or more times as long as eitherJ ot the other sides, which are equal.

The long side consists of a beam or fence, A, which has a perpendicular face, a., and the back side is beveled at b, terminating in a' sharp edge, c, at the lower front corner.

A metallic facing, d, is secured to the perpendicular side of the fence A, the lower edge of which facing extends downward below the feneeA and has a thin lower edge. The equal sides B B are joined together at e, and their other ends are firmly secured to the fence A at f.

A transverse leveli ng-beam, O, extends from the junction ot' the sides B B to the fence A, at right angles with said fence, and is secured thereto and to the sides B B at a'.

Two load-platforms, D D, are affixed to the fence A and sides B B, about half-way from the leveling-beam C, to the extremities of -the fence A. l

Two n'iold-boards, E E, rise from the top of the annular sides B B, and are held in position by pins or other suitable fastenings.

Hooks l 2 3 are secured to each of the sides B B, at suitable distances apart for chains F, G, and H to connect, by which the plow is drawn and guided.

The center draft-chain, G, is intended to take most of the strain when the plow is in use, and the auxiliary brace-chains F and H serve to guide the plow, and prevent it from swinging laterally to any extent. The auxiliary brace-chains are connected with the center draft-chain by hooks g and h, and may be tightv ened or slackened by hooking intodift'erent links 4 5. 6 7 8 901;' the center draft-chain, several `of which are provided for that purpose.

My improved snow-plow is designed for breaking out town-roads, which are frequently graded around side-hills, where it is necessary to move the snow oli' at one side, but may be used `on any common road, and, as both ends of said plow are alike, it may be drawn in either direction by removing the chains from one end and hooking them on at the other..

As my improved snow-plow enters and passes through the snow (in either direction) the' fence A and facing d present sufficient resistingsurface to prevent the plow from being moved sidewise when the snow is being forced outward by either of the inclined or angular sides B B 0r mold-boards E E.

.The leveling-beam C serves to level oft" any inequalities, and to fill up cavities which the plow might pass over.

After t-he road has been plowed out, the furrow may be considerably widened by ruiming the fence A along in the middle portion of said furrow. The lower edge ot' the facing' d cutting into the snow exerts sufficient resistance laterally to cause either of the angular sides to force the snow out-ward and form a wider track.

1f teams are met in plowing out roads, my improved plow may be easily vturned upon its side, as shown in Fig. 2, teams allowed to passfthe plow turned down to its working position, and plowing resumed without the inconvenience ot' shoveling around it to get auother team past, as is common with all ordinary snow-breakers used on country-roads.

I claim- 1. The combination and arrangelnent of the fence A and facing d, sides B B, leveling-beam O, and 1nold-boards E E, substantially as and for the purpose set forth.

2. In combination with a snow-plow constructed and arranged as above stated, the employment ofthe auxiliary brace-chains F and H, connected with the center draft-chain, G, substantially in the manner and for the purpose speciied.` 1
