SNOWPLOW.

Application filed November 16, 1925. Serial No. seam.

This invention relates to means for clearing pavements, highways and roads generally-of snow and provides a plow which may be readily applied to or removed from a tractor, and which maybe adjusted at the front to admit of the propelling force being applied to hold the. nose of the plow upon the road with a greater or less pressure as required.

The invention furthermore provides a plow which may be cheaply constructed, maintained at a little or no expense and which is effective, durable and easily manipulated.

While the drawings illustrate a preferred embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied, and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof. I

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,-

Figure 1 is a top plan view of a snow plow embodying the invention, showing the same applied to a conventional'tractor.

V Figure 2 is a vertical, central, longitudinal sectional view of the plow,

Figure 3 is a vertical, transverse sectional view on the line 3'3 of Figure 2, looking in the direction of the arrows, and

Figure 4 is a detail perspective view of the nose of the plow.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates a tractor of any approved to demonstrate the application of the invention.

V The plow comprises clearer blades 2, which are oppositely inclined and of a length to extend along opposite sides of the tractor, as illustrated most clearly in Figure 1. The .blades 2 may consist of planks and are reinforced at their lower edges by angle bars 3 which sustain the wear and strengthen the blades. Couplings 4 and 5 are applied to the nose of the plow and connect the forward ends of the blade 2, the coupling 4 being disposed. against the type the same being illustrated forward'side of the-nose andengagin'g, the

outer faces of the blades2" adjacentthe polnt, whereas the coupling- 5 is arranged upon the rear side of. the. noseiandincontact with the rear faces of theblades 2 adj acent the point, the two couplings 4] and 5 being riveted or otherwise secured by suitable fastening means, The lower forward portion of the nose is. beveled, as (indicated 5 at.6, to ride over obstructions as willbe readily appreciated. The forward ends of the reinforcing bars 3 underlap the lower ends of the wings comprising the forward coupling 4. The lower, rear corners of the 7 blades 2 are beveled, as indicated at 7 to insure riding over obstructions when the plow is backed.

A cross bar 8 extends between the forward ends of the blades 2 and receives a clevis 9v 7 which is attached to the rear side thereof, and which comprises a vertical rib in which is formed a vertical series of openings 10 which provide for vertical adjustment of a push bar 11 which is attached at its rear the inner faces of the blades 2 adjacent the nose and support the cross bar 8 and sustain the forward pressure exerted thereon. Stay chains 13 connect the rear end of the push bar 11 with the blades 2 and serve to prevent lateral displacement of the plow and cause the same. to run in a straight line.

A rear cross bar 14 is connected centrally to the rear of the tractor 1 and projects beyond opposite sides thereof and the projecting ends are bracingly connected to the respective blades 2 by means of bars 15 and 16, the bars 15 being longitudinally disposed whereas the bars 16 are oppositely inclined. These bars 15 and 16 may be connected to the respective parts in any preferred way and when the bars consist of wood they are reinforced at their ends by metal straps 17 which are connected to brackets 18 applied to the parts to which the stay bars 15 and 16 are connected. It is also observed that similarbrackets 18 are attached to the blades 2 for reception of the outer ends of the chains 13. Strips 19 are attached to the in; ner. faces of the blades 2 and extend vertically and serve to strengthen the blade and 1 also to receive the brackets 18 which are connected thereto.

The snow plow Will be of such dimensions as to receive the tractor between the blade 2, longitudinal stay bars 15 and 16 and the rear cross bar 14, as shown most clearly in Figure 1. In the operation of the device the plow is advanced by a pushing force applied thereto through the bars 11, 15 and 16, lateral displacement of the plow being prevented 'byrthe parts 13, and 14-, as Will be readily appreciated. This construction is such as to admit of the plow being readily placed in position for use and easily and quickly removed to be stowed away when not required for immediate service.

' Having thus described the invention, 1 claim:

The combination with a tractor, of clearer blades at. the sides thereof and forwardly ends of the said blades.

converged, a cross bar connecting the, clearer blades adjacent their forward ends, a clevis attached. to the cross bar and having a vertical rib in Whicha vertical series of open-- ings is formed, a push bar adjustably connecting the front end of the tractor With the stay bars at the sides of the tractor connecting the outer ends of the rear cross bar With intermediate portions of the said blades, and forwardly diverged staybars connecting the ends of the rear cross bar With the rear In testimony whereof I affix my signature.
