Positioned onthe underside of thefi'ont I end portionfof the shovelelement is pair of l runners 4, as carrying means therefor, the said runners being spaced'apart and pivotally connected at their front ends and being 'ad-J g justed'aslhereinafterdescribed." Y As a hitching means; for the shovel portion of the plow to a tractor, a 'beam" 5, is pivotally connected to each side thereof iin close proximity .to the runner elements're- 7 spectively as shown at A,- the said beams'ex tendingrearwardly and being in parallelism with their respective sides of the. tractor and havingaflcross bar 6, connecting: the rear ends of said beams by which means the plow is hitched to a tractor as conveyingr 'ni'ez'in'stherefor, it being'understood that the exact ,di sclosure' of the hitching means may vary require for the dififerent r y p v 'otthe beams in close proximity to the rearend of the shovel is a j strut element 7 as carrying means therefor, V

the said: struts being 'apertured as at; '8 re- 1 "sp'eetively, it'being understood that the "said strut members arein pairs and spaced apart as' jshown' in Fig; i 4 by whiehfmeans the extended. ends ofthe side carrying beams 9 will Islidably engage on the outside thereof and being stationarily supported by. apinorgbolt 10, engagingflin theapertiiresof the struts and similar "apertures in the extended end portions that "willregister 7 with the' first said apertures asthe beams are rocked'vertically' to'their lselectedpositions Oppositely positionedto each shovel beam is a brace member 11, having one end secured V to the beam 5, the other endto the upper extremity of the strut, by which means a truss -'is formed to carry the load imposed on the shovel without serious deflection of the said beam 5. i :When transportation of the snow plow is r a bolt as connectingmeans for the shovel, the

required; the shovelportion thereof maybe elevated to a position shown by dotted lines.

"B, in Fig.1 through the medium of'a cable 12 and a spool 13 on which the cable is wound,

employed to suit the styleoftractor selected other than. that shown in the drawingsif" e '1 Positioned on'the shovel element is a mould board 19, preferably Inadea V-shape,

the apex thereof having a plate 20 attached thereto and being aperturedas at 21 to receive rear ends. of the mould board being secured to the said shovel by means of straps-22 respectively, the said straps extending across the ends and. being secured to theshovel by nuts-.23 threadedly engaging thereon by which" the V-shaped mould board is easily placed and removed.

-.Intermediately. positioned to the apex and rear end ofthe mould board is a bracing ele ment 24 as means to resist the pressure i'mposed at either side thereof.

In the event of the road bed being irregular as to its surface or the earth mi-ry;. it may become necessary toraise the share of the shovel to avoid cleaving the earth.. As a convenient means to raise and lower the same; the run- 11ers heretofore referred toare adjustablyarby turning thelatter describedshaft by a. wheel 30 on the outer end. thereof, the said ranged by means of jack elements. 26' positioned between the rear portion of the runners the body of theshovl; .the jacks being operated byshafts 27 a'nd-28 respectively, the said shafts extending from their respective jacks in axial alignment and entering ahousing 29 in whichthe same are trunnioned, it i being understood that the said housing is securely aifixed to the body of the shovel, and functions as an enclosure for bevel gears r'gidly attached to the adjacent ends-of the said shafts. I v V As ameans to rotate the said shaft, a sec- ;ond shaft 30 positionedat right angles thereto is likewise trunnioned in the housing and has a beveled gear secured on the end thereof In mesh with each of the first said gears and jacks are operated. c V V V V I The rear end portion of each of the runners has a brace member 31Ipivotallyengaging on As a modification for the floor of the shovel,

' I have provided a wing. member 33 hingedly connected to each sidethereof,theouter edge of. each of the said wing members diverging rearwardly and being so arranged that the bank of the snow will be vertical or inclined outward at the option of the operator as the plow is driven therethrough. 1

a In Figure 9 is shown one wing of the plow positioned on a plane with the top side of the shovel, as means to slantingly position the bank of snow as shown at 34 in Fig. 11, while the wing on the oppositeside ofthe shovel is droppedto a vertical position to form a verticall dis o sed bank as shown at 35. The latter escri ,d position of the wing tends to trowel the'wall to a compact smooth surface and the *outer end portion of the mould board which extends overthe side as shown at X in Fig.' 9,, will uniformly smooth the top of the bank as shown at 36, in Fig. 11.

While I have shown and described the wing members to be hingedly connected, I do not confine the assembly to that alone as they may be detachably arranged,*but in either event competent bracing Wlll beprovided when the said wings are positioned on the plane with the upper face of the shovel, andsuch other modifications may be employed as lie Within the sco pe of the appended claim, and-what I 'claimfas new and desire to secure by Letters Patent is: i 'In a snow plow of the class described comprising a shovelf member and a V-shaped mould board carried by the shovel, each member of the mould board being perpendic} ular with respect to the plane of the shovel, a pair of beams pivotally attached to the shovel, a spaced distance from the share of the shovel, the otherend pivotally engaging at the rear of a tractor as propelling means for theshovcl, a strut upwardly extending and secured to each of the beams, the strut having a plurality of aperturesspaced longitudinally therealong, a, brace member attached to and extending forward from the rear end of each ofthe' beams, the'forward end of each brace and each of the rear corners of the shovel being carried by the struts at the tops thereof, by which means the upward slant of the shovel maybevaried and a truss function obtained as a result of the assembly,

the forward end. of the shovel being carried and spaced from the ground by a'pair of arcuate'runners, allv substantially as shown. In testimony whereofI afiix'my signature.
