SNOWPLOW.

Application filed February 27, 1928. Serial No. 257,875.

The invention relates to a new and improved form of snow plow tobe preferably drawn by a team, provision being made whereby the plow is held to its course and cannot slide laterally. v

It is one obj ect of the invention to provide a snow plow ofthe general type having a scraping blade and a pair of runners, in which novel provision is made for permitting the blade to be swung forwardly or rearwardly to vary the width of out, according to the width of the road or. the depth of snow and consequent resistance to pull.

In its preferred form of construction, the plow embodies a relatively long and. a comparatively short runner between which the scraping blade extends, and it is a further object to provide unique means for raising the front end of the long runner when the plow is to be turned, thus greatly facilitating lVith the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described I and claimed, description being accomplished by reference to the; accompanying drawings.-

Fig. 1 is a top planvlew.

Fig. 2 is a side elevation.

Fig. 3 is a fragmentary longitudinal section on line 3-3 of Fig. 1. a i

Figs. 4 and 5 are detail longitudinal sectional views on the correspondingly num-- bered lines of Fig. 1. Figs. (Sand 7 are detail vertical transverse sections on lines 6-6 and 7- -7 of Fig. 4. Fig. 8 is a transverse sectional view on line 8-8 of Fig. 1. i

Fig. 9 is a small plan view showing'the machine adjusted for a narrow cut.

The preferred details of construction have beenillustrated and while these details will be herein specifically explained, it is to be understood thatwithin the scope of the invention as claimed, variations may be madel The numeral 10 denotes a relativelylong runner preferably formed primarily of a length of channel metal, the front end of sa d runner being provided with an appropriate hitchll. Hinged to the front portion of the runner 10-is a suitably shaped scraping blade 12 having a steel cutting edge 13, said blade projecting laterally and rearwardly with regard to said runner. Behind the rear end of the blade 12, is a comparatively short'runner 14 preferably formed of channel metal, said rear end of the blade 12 being hingedly connected with the front end of said 'runner 14. Between the two runners 10-14 is a horizontal plate 15 having a plurality of bolt holes 16 at spaced points. Two inwardly converging, transverse bars 17-18, are secured at their outer ends to the runner 14 and at their inner ends to the plate 15. Two similarly converging transverse bars 19-20 are secured at their outer ends to the runner 10.

The inner ends of these bars may well overlap each other and lie upon the plate 15 and a bolt 21 is passed through the innerends of these bars, said bolt being receivable in any of the openings 16. When this bolt is removed, the blade 12 may be swung forwardly or rearwardly to dispose its outer end at thedesired distance from the runner 10, thus regulating the width of cut. Then, after proper adjustment has been made, the parts are again secured by reinsertion of the bolt 21 in the proper opening.

. The hinge axes of the blade 12 are inclined rearwardly and are parallel with each other, and this relation of axes has a tendency'to incline the short runner 14 in one direction or the other, when the blade 12 is swung forwardly or rearwardly. To overcome this tendency, instead of hinging the outer or rear end of the scraper 12 directly to the runner 14, Ihinge it to a horizontally elongated plate 22 as shown most clearly in Figs. 1 and 5, the plate being connected with the runner by bolts 23 passing through vertical slots 24.

When these bolts are loosened, swinging of the blade 12 will incline the plate 22 somewhat, but the runner 14 will remainhorizontal. Then, after proper setting has been effected, these bolts are again tightened. 'Appropriate braces 25 are provided for the blade 12, the rear ends of these braces being adjustably secured as'at 26, to permit any necessary movements of them during setting of the plowvwith the blade 12 at one angle. or another.

In the present showing, two curved reinforcing bars 2728 are, secured to the rear side of the blade 12 at its outer and inner ends respectively, and the braces are connected with the upper portions of these bars. Between their ends, the bars 2728 are provided with rearwardly projecting lugs 2980 respectively. Lug 29 is received be tween and is spaced from upper and lower forwardly projecting lugs 31-32 on the plate 22. Lug is similarly received between vertically spaced lugs 3334 ona plate 35 which is secured to the runner 10. Vertical screws 36-37 are swiveled in the lugs 3132 and 33-34 respectively, and are threaded through the lugs 29-30, said screws having hand wheels or the like 38, By rotat-ing these hand wheels, the entire blade 12 is raised or lowered as required.

Front andrear plates 39-40 contact with the outer side ofthe runner 1O 'and project downwardly below the same to bite into the snow and hold said runner against lateral slippage, said plates being preferably secured to the runner by appropriato'bolt and slot connections 41. A similarplate 42 is disposed at the inner side of the channel metal runner 14 and is secured by a bolt and slot connection 43, to the vertical flange 44 of an angle metal bar which extends longitudinally of said runner 14, in opposed relation with the vertical webofthe latter. The base 45 of this angle metal bar is secured by rivets or the like 46 upon the base flange 47 of the runner 14.

Near itsfront end, the lower 'edgeot the runner 10 is formed with a longitudinally extending notch 48. WVithin this notch, is

a turning shoe 49 which is swiveled on the lower end ofa vertical screw 50 carried by the runner 10. Normally," shoe 49 is confined totally within the notch'48. When the entire plow is to "be turned around or otherwise turned however, the screw 50 is operated to tion of the vertical web of the channel metal bar, of which the runnerlO is formed, and

p I cut awaya length of the base flange 51 of this bar, of less length however than the notch, leaving a portion 52 of said base flange projecting beyond the-rear edge of said notch. This base flange portion is curved upwardly as shown at 52 and is riveted or otherwise secured to the rear end of a horizontal plate 53. Between the front portion of this plate and the top flange 54 of the runner 10, is a vertical sleeve 55' which ispreferably flanged a single met-al'bar.

" be made, as above "stated;

at its ends at '56 and riveted or otherwise secured to said flange 54 and plate 53. This flange and plate are formed with openings alined with the sleeve, and the screw 50 passes through said openings and sleeve, being threaded into the latter. As above described, the shoe 49 is swivelled upon the lower end of this screw and when the shoe is idle, it may well contact tightly with the lower side of. the plate j I prefer to form the shoe'49prihcipally of This bar'is bent between its ends to provide upper and lower horizontal portions 57-58, integrally "connected at their rear ends by 'asp'acingportion 59 The tront'end 60 of the portion 58is curved u pwardly and the front end ofthe portion 57 is bentdo'wnwa'rdly at 61 and secured to said end 60,"being then extended rearwardly as at 62 and securedto a verse-alarm lilwhich is maybe preventedbya cotter pin- 01 the like 64 passed through said screw,- torinstancqunw der-the bar portion62.

Preferably, the runner 10 'is provided with an'appropriate seat 65 torthe driver, as his weight assistsmaterially m' holdmg the plow on its course. 7
