SNOW-PLOW,

Specification of Letters ma.- P tented July 15, 1913.

Application filed May 17, 1912. Serial No. 697,972.

To all whom it may concern:

Be it known that I, JOHN D. BEAVER, a citizen Of the United States, residing at St. John, in the county of Stafford, State of Kansas, have invented certain new and useful Improvementsin Snow-Flows; and I do hereby declare the following to be a full, clear, and exactdescription of the invention,

such as will enable others skilled in the art to which it a-ppertains'to make and use the same. a

This invention has special reference to new and useful improvements in snow plows and more particularly to a device of improved construction attached to the front of locomotives andstreet cars for cutting into snow and throwing the same to opposite sides of a' trackway.

The invention consists in providing a snow plow eml'iodying opposite mold-boards or wings secured together to form a sharp penetrating po nt. and rotatahly supporting defleoto'r wheels for discharging the snow at the opposite sides of the track, while means are also provided-to prevent the entrance of snow between the wheels and mold-board as a well as to control the operation of said wheels. I, With the above and other objects in view,

the invention consists of certain combina tions and arrangements of parts as Wlll be, hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my improved snow plow attached to a locomotive, the front part of which is shown in general outline. Fig. 2- is a top plan view thereof. Fig. 3 is a bottom plan view of the device detached. Fig. 1 is a central longitudinal sectional view thereof taken on the line 44 of Fig. 2. Fig. 5 is a cross sectional view taken on the line 55 of Fig. 1. Fig. 6 is a horizontal sectional view taken on the line 6-43 of Fig. 1.

As illustrated, my improved snow plow is shown as attached and forming the plow of a locomotive 10, the front part of which is shown in general outline and said plow comprises opposilc mold-hoards or wings 11 disposed in convergent relation from their front to their rear ends and having their top and bottom edges .12 and 13 respectively disposed in parallel relation while the forward edges of said mold-boards are inclined downwardly and are secured together to form a sharp penetrating point 14 to readily out into the snow and to discharge the same at opposite sides of the plow against the -mold boards while the top edges 12 are formed with or connected by a top portion or shield plate 15 servingto r1gidifythe structure and prevent the entrance of snow from the top. The opposite mold-boards 11 are connected at their rear ends and above their lower edges by a cross brace 16 which serves for the attachment of the plow to the locomotive and also serves to hold the said mold-boardsin. spaced relation while spaced parallel and forwardly inclined bearing ,members v 17 are connected to the cross brace .16 at their rear ends and are secured at their forward portions to the inner faces of the mold-hoards adjacent the lower edges of the latter to form brace po-rtlons 18 to reinforce the plow point.

Rotatably journaled in the bearing members 1-7 are the ends of a drive shaft 19 upon which are rigidly mounted traction wheels 20 to travel on the track rails 21 and impart rotation to the shaft while the beveled gears 22 are carried by the-inner faces 'of said tract-ion wheels and, normally engaged by smaller beveled gears 23 rotatably mounted on the inner ends of a pair of inclined driven shafts 24 rot-atably supported in crossed relationand operating through the opposite mold-boards at their outer ends. Mounted on said outer ends are deflector wheels or disks 25 having tapered hub caps 26 preventing the collection of snow thereon and also provided with radial deflector plates 27 on their outer faces, such blades tapering toward their inner ends and extending rearwardly so as to deflect or discharge the snow cut by the plow at opposite sides of the track during the rotation" of such disks or wheels.

Arcuat'e or crescent-shaped guard plates 28 are secured attheir forward edges to the (ipposite 1nold-boards in front of the wheels or disks and have their rear portions offset from the mold-board and encircling the disks or wheels beyond the outer faces of shaft 19 and has traction wheels 30 on its tion and control while the driving means provided insures of positive operation of In order to assist the rotation of the snow wheels or disks and secure the benefit of the full weight of the plow for this purpose, a drive shaft 29 is rotatably mounted in the bearings 17 forwardly of and beneath the ends, while the drive chain 31 is engaged around a sprocket wheel 32 rigidly mounted centrally of the shaft 29 and a sprocket wheel 33 centrally'mounted on theshaft 19 and as these sprockets wheels are of thesame relative proportions or diameters as the traction Wheels to which they are re spectively connected, a. uniform speed of rotation willbe imparted to the shaft 19, driving the plow wheels. The shafts 24 are providedwith clutch members 34 splined thereon and controllable by throw'levers 35 for moving the same into and out of engagement with clutch members- 36 carried by the gears 23 so as to control the operation of the snow or plow wheels and throw the same into or out of operation as desired. An outwardly and rearwardly directed shield 37 is carried by the rear end of each mold-b0ard for further deflecting the snow beyond the tracks, especially in windy weather.

It will thus be evident that I have provided a very efiicient snow plow which embodies a very durable construction and which is also capable of convenient operathe snow wheels.

I claim: t 1 1. A snow plow embodying opposite I mold-boards united at their-inclined forward edges, a top guard plate for said rotating said wheels and-arcuatefguard plates secured to the mold-boards and hav ing offset rear portions encircling and overlying the front'port-ions. of the wheels to prevent the entrance of snow between the latter and said mold-boards.

2. A snow plow comprising a pointed casing having side portions, a brace connecting the rear ends of said side portions and adapted for attachment to a locomotive, bearing members connected to the brace at their rear ends an secured to the inner face of saidside portions/at their forward ends, shafts rotatably mounted in the hearing members, traction wheels carried by the shafts for rotating the same, driver gears carried by one of the shafts, transmission gearing connecting. a the shafts, deflector disks disposed adjacent to the opposite outer faces of the casing-and having deflector plates, inclined shafts rotatably support-ing said deflector disks, transmission gears carried by the respective inclined shafts and meshing with said driver gears, and means for throwing said inclined shafts into, and out of operative relation with the first said shafts.

'- In testimony whereof, I aflix my signature, in presence of two witnesses.

' JOHN D. BEAVER.
