Application led May 17, 1926. Serial No. 109,618.

This invention relates to improvements 1n snow-plows and has for its primary object to provide a device of this character that.

may be linstalled upon the forward end of a conventional tractor in order that the same may be pushed along a road or public high- Way to clear the snow therefrom, the devicev `being operatively lconnected. to the power take of shaft of the tractor.

to provide a device ofthis character that may b`e readily associated with a conven` tional form .of tractor without altering the construction of the tractor and without-requiring any'unusual skill in theapplication of the plowto the tractor.

Other objects will become apparent as the lnature of theA invention will be'better understood, the same comprising the novel 20 form, combination, and arrangement of parts hereinafter more fully descrlbed, shown in the accompanying drawings and claimed.

In the drawings wherein 'like'numerals designate'like parts throughout the several ae views:

Figurel is al side elevation of my im?` proved snow plow as actually associated witha conventional form of tractor. p

Figure 2is a bottom plan view ,of the tractor and plow.

Figure 3 is an enlarged top plan view of the snow. plow per se. l l

Figure 4 is a front end elevation thereof. li'gure 5 is a detail longitudinal section, Figure 6 is an enlarged top plan view of a supporting and steering skid for the plow that isoperatively connected with the steering wheels of the tractor inorder that the plow will be guided in the same direction with the tractor.

.Now having particular reference to the drawings, 5 .designates generally a conventional tractor which is disclosed as bei one of theFordson type,- the construction o f 4which is well known and even a generalV description is therefore not necessary. My device constitutes the provision of a palr of' spaced parallel' and horizontal frame bars wise rigidly secured to the forward end pf the chassis bars of the-tractor as clearly dis- An additional object of the invention is the housing 6-6 that are so constructed as to 'ermit the inner ends of the same to be holte `or other-1 orce 0105614 Dboth Figures 1" and :2. .'Theffor#r ward ends of these bars 676 are formed with depending arms 7 fro'm the lower ends of which extend forwardly projecting and -f downwardly inclined bars 8 u on whlch is supported .a relatively large fan housing 9, the lbottom wall 'of which ,is

so formed as to present -a horizontal front edge as clearly disclosed in Figure 4, and to` to conical which horizontal edge is pivotally connected a horizontal plow b at its forward edge with spaced lteeth 11 ade 10 that is equippedv same to be fed upwardlyv upon the plow blade intothe housing'in an obvious manner. Y.

Arranged transversely upon the barst-#6 are a. pair of spaced thatareinterconnecte at their opposite ends arallel beams 12-,12 c

by cross .bars 13e-13. Journaled' within 'bearings 14E intermediate -the 'ends of the s beams 12-12 is a longitudinal shaft 15 that extends forwardly through an opening 16 in .the rear wall ofthe housing 9 and rejects loutwardly thereof as' more clearl in Fi ure 5 .at which' outer end t e same' is provi ed with a snow cutting auger 17.' At

Mounted uponI the'vshaft 15 .wi

housing? is an auger fan unit2e that wr i snow fed into Athe housing in afreai'-, |105 65 that will bite into the snow and cause the action of the same'in order to discharge the snow through an exhaust opening 25 1n the `top of the housing and at the` rear side thereof, and from which 'said exhaust opening leads a laterally extending pipe 26 to convey the snow to the side of the roadway.`

Mounted at the opposite sides of the houssaid chain lengths 44-44 obviously tendlng ing 9 are snow cutting reels 27--27 that serve to permit the plow and tractor to pass between kthe snow anks without interference, said reels consisting each of a vertically inclined shaft 28 suitably journaled at its opposite ends and being equipped at its upper end with a beveled gear 29 that is in mesh with a beveled gear `30 upon the forward end of a shaft 31 extending along the adjacent sides of the housing and being equipped at its rear end with a beveled gear 32. The gears 32 of the shafts 31 are in mesh with beveled gears 33-33 upon the ends of a shaft 34 which is arranged in parallel relation with the heretofore described beams 12-12 and is journaled at its opposite ends within suitable bearings arranged upon the beam connecting bars 13-,13'A Said shaft 34 is equipped with a spur gear 35 adjacent its right hand end, the teeth of which are in mesh with the teeth of a similar gear 36 upon the heretofore mentioned shaft 19 in order that when said shaft 19 is rotated by reason of the `power take off -shaft of the tractor such rotation willY be imparted to the shafts 31 and consequently the cuttingv reels 27-27 will be operated for a purpose heretofore described. v

Mountedl beneath the fan housing supporting bars 8 is a horizontal board 37 to thecenter of which is pivoted .as at 38 a horizontal skid-board 39 'equipped at its outer ends with sleigh runners l1()-40. The pivotal` connection 38' between said boards 37 and 38 extends-loosely between cross slots yin the respective boards as clearly disclosed in Figures 2, 5 and 6, said slots permittin the skid to have a limited transverse and longitudinal sliding movement to facilitate the proper steering of the low when the front steering wheels of t e tractor are turned in a manner hereinafter more fully described.

Secured to the rear ends of the runners of the skidare the forward ends of chain lengths 41-41 which chain lengths are extended diagonally .across the under side of the plow in opposite directions and are then trained over pulleys 42-42 supported from the depending arms 7 a's shown in Figures 2 and 5. The chain lengths are then extended diagonally beneath the plow in opposite directions and are secured at their inner ends to arms L1:3-43 that are attached to the wheels supporting spindles of the tractor fronty steering wheel in order that when saidp wheels are turned for steering the tractor, a corresponding movement of the in similar directions with that of the tractor.

The forward ends of the runners 40-40 of the skid have connection with chain lengths 44--44 that are extended inwardly and toward the front end of the housing 9 at which point they are anchored as at 45,

` snow plow that is well adapted for all the purposes heretofore designated and even though I have herein shown and described the invention consisting of certain detail structural elements it is nevertheless to be understood that departures may be had.

therefrom without effecting the spirit and scope of the appended claims.
