SNOWPLOW Filed Dec, l5, 1929 4 Sheets-Sheet 4 INVENTOR ATTORNEY Patented Jan. 20, 1931 PATENT OFFICE RAYMOND LEE HULSLAN'DER, OF WORTHINGTON, MINNESOTA p sNowrLow Application -led `December 13, 1929. Serial No. 413,846.

-This invention relates to a snow plow, `the general object of the invention' being to provide a scoop for scooping up the snow as the plow is pushed into the snow, with a con- B caved part for receiving ythe snow from the scoop and a wheel having blades thereon which pass over the concaved part when the wheel is being rot-ated .so as to throw the snow to one side of the road or the other, ac` cording to the direction of lrotation of ythe Wheel so'th'at the snow is not banked in the road, but is thrown to one side of the road.

Another object of the invention is to provide cutting blades on Vthe wheel which exe tend forwardly of the other blades Aand act to dcutand loosen the snowbefore it is operated on by said other blades. Another obj ect of the invention Ais to` provide hinged wings for increasing the length of the concave when the plow is `working in deep snow and to provide a Apointed device on 'the hub of the wheel for preventing deep snow from pressing against the front face of the wheel.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to 4'be hereinafter fully described, illustrated in the accompanying drawings and claims.

'In describing the invention in detail, reference will 'had to the accompanyingvdrawings wherein likecharacters denotelike or 'corresponding parts `throughout the several views, 'and in which :-w p

Figure 1 is an elevation, with parts in sec# tion, showing the plow attached'to atractor.

Figure 2 is a top pla-n view of Figure `1.

FigureB is a front view of the plow.

Figure 4 is av vertical sectional View through the plow.

Figure 5 is 'a rear view of the plow.

Figure 6 is a sectional detail view showing the means for driving the wheel of the plow from the tractor.

In these views, fthe numeral 1 indicates a housing having its sides sloping upwardly and inwardly to its fiat 1top`.2 andthe numeral 150 3 indicates a "concaved part vattached to *the specifically pointedl out in the appended front of the housing at its lower end, and 4 indicates a'scoop attached to the front edge of the concave and adapted to scoop up snow as the device is moved along so that the snow will enter the concave. Side pieces 5 are connected with the `sides of the housing and the ends of the 'concave andv scoop andk form groundengaging shoes. Abrace 6 extends from the bottom of the housing under the concave and scoop and acts to brace theparts. A horizontally arranged bearing member? is fastened to the top ofthe housing and rotatably supports a shaft 8 to which the hollow hub of a wheel 9 is. fastened, the hub portion having it-scorners tapered to form the blades 10. "The wheel is arranged above the concave in such 'a manner that its blades will pass over the same as fthe wheel is rotated. Flat blades 1l are fastened to the wheel between the blades 10 and these blades are bent, as at 12, where they join the wheel, so that the major portions of the blades 11 are in advance of Jhe wheel. Each vblade is sharpened or beveled on each edge. A pointed -meniber'l is connected with the front face of thehub and is composed of substantially triangular shaped parts connected together at their inner ends, with their small ends arranged adjacent the point of connection of the blades 1'1 with the wheel.

A substantia'Hy L-`shaped wing 14 is hinged to the front of the housing, at each side there# of, thesewings forming extensions of the'conca-ve when they are swung forwardly and when swung rearwardly,they will rest on the sides of the housing so that the concave will be ofless length than when the wings are in forward position.

A pair of beams l5 have their front ends connected with the housing and their rear ends are adapted to be pivotally connected wit-ha part of a tractorv A, as shown at 16, and a shaft 17 has its front end journaled to the rear face of the housing and carries a sprocket V18 over which passes a chainV 19 which also passes over a large sprocket 20 on the `rear end of the shaft 8 which carries thel `wheel 9. A shaft 2l is rotatably arranged in a housing V22 supported by the hangers 23 from the tractor, and this shaft 2l `is connectthrough the concave.

ed by the couplings, shown generally at 24, with the shaft-,17, so that the plow can have movement in relation to the tractor without affecting the'driving connection between the shafts 17 and 2l. A sprocket 26 is connected with the rear end of the shaft- 17 and a chain 27 passes kover this sprocket and over a sprocket 28 on a shaft 29 arranged in a housing 30. A pair of gears 31 is fastened to the shaft 29 within the housing and one of these gears meshes with an idle gear 32 in the heusing, which in turn meshes with `a gear 33 loosely arranged on a shaf this shaft 34 being driven from one of the drive shafts of the power plant of the motor by the chain and sprockets, shown generally at 35. A gear 36 is loosely arranged on the shaft 34 and meshes with the other `gear 31. A double clutch arrangement 37 is. slidably mounted on the shaft 34 and is adapted to be moved from a neutral position into engagement with either of the gears 33 or 36, so as to drive the shaft 29 in one direction or the other. This clutch is manipulated by a shift lever 38. Y n

A worm gear 39 is fastened to therear end of the shaft 29 and meshes with a worm gear 40 on a shaft 41 transversely arranged on the tractor and having the drums 42 atfits ends to which cables 43 are connected. YThese cables pass forwardly over the pulleys 44 at the front of the tractor and then pass downwardly and are connected with the front ends of the beams 15, as shown at 45.

A clutch 46, including a lever 47, is provided for connecting and disconnecting the gear 40 with the shaft 41. The shaft 4 1 is also provided with the brake means, shown generally at 48.

From the foregoing it will be seen that th plow can be raised and lowered when the shaft 41 is connected with 1the shaft 29, so that the plow can be adjusted to pass over obstructions or can be held in raised position when it is being conveyed to and from the point of use and that the wheel of the plow is driven in either direction from the power plant of the tractor, though it will, of course, be understood that a separate motor may be provided for driving the wheel, if desired. Y

The wheel will remove the snow from the concave and throw it a distance from thek road as the blades 10 on the wheel pass This will prevent banks of snow being formed on the. sides of the road. The blades 11 act to cut the snow in front ofthe wheel and loosen the same so that the blades 10 can properly operate on the same and the scoop Vwill pick up the snow and cause it to pass into the concave. When the plow is operating in deep snow, either or both wings should beraised to increase the length of the concave, as shown in Figure 3, though these wings are not needed in light tion that the advantages and novel features t 34 in the housing,

snow. The pointed device 13 also acts in deep snow to cut the snow from in front of the hub of the wheel and prevents this snow from retarding the forward movement of the plow. The rapidly revolving wheel, having its blades Vpassing through the concave, will set up a centrifugal force which acts to throw the snow a considerable distance away from the road.

It is thought from the foregoing descripofthe invention will be readily apparent.

It isto be understood that changes may be made in the construction and in the combinationv and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
