SNOW-PLOW AIN'D SNOW-LOADED.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed October 11, 191s. Serial No. 251,757.

T1 all whom it may concern:

Be it known that I, WALTER Imsnm Sumo, a citizen of the United States of America, and resident of the town of St. Francis, in the State of Maine, in the United States of America, have invented certain new and useful Improvements in Snow-Flows and Snow-.Loa ers, of which the following is the specification.z

The invention relates to improvements in snow plows and snow loaders, as described in the present specification and illustrated in the accompanying drawings, that form part of the same.

The invention consists essentially in the novel arrangement and construction of parts, whereby the roadway is cleared and the snow directed away from the machine in the delivery thereof.

The objects of the invention are to provide in a snow clearing machine certain advantages, which constitute subject matter divided from copending application Serial No. 250,075 and improvements on the machines described in the specifications attached to Letters-Patent of the United States Nos. 1,084,498 and 1,093,493 on J anuary 13th, 1914, and April 14th, 1914, said improvements much facilitating the operation of the machine and insuring a wider application of the same; and generally to furnish a machine to the public, that will prove efficient and economical for clearing roadways of accumulations of snow in the winter time.

In'the drawings, Figure 1 is a side elevation of the machine.

.Fig. 2 is a front elevation of the machine showing the plowshare' and an extension chute for loading purposes and omitting the running gear.

Fig. 3 1s a side view of a ortion of the machine showing the particu ar parts illustrated in Fig. 2.

Fig. 4 is a plan view showing the same parts pertaining to this invention, and illustrated particularly in Figs. 2 and 3.

Like numerals of reference indicate corresponding parts in eachfigure.

Referring to the drawings, the main frame 1 is carried on the sleds 2 and 3, the former sled 2 bein the front or guiding sled and the latter s ed 3 the rear sled, said sleds being equipped with means for turn g, so as machine may be hauled by a motor driven vehicle.

The driving gear shaft 4 is journaled in suitable bearings supported by the frame 1 and is operatively connected to the motor ,5.

The beams 6 swin slope downwardly. he bars 7 are rigidly secured to the upper sides of the beams 6 and the bars 8 are rigidly secured to the lower sides of said beams and extend beyond said bars 7, the latter being bent downwardly and secured to the bars 8 by means of the pivot bolts 9.

The bars 10 extend upwardly from the pivot bolts 9 and are p'ivotally secured to cranks 11, fixedly mounted on the shaft 12, said shaft 12 being rotated by the segmental gear 13. The segmental gear 13 is 0 erated by the worm 14 at the end of the s aft 15 on which is mounted the hand wheel 16.

It will now be seen that by turning the hand wheel, the worm, coactlng with said segmental car, will operate said gear and consequentfi the cranks, thereby raising or lowering the said beams through said suspension bars 10,

The bearings 17 are supported at the lower ends of the beams 6 and in these hearings the cutter shaft 18 is journaled.

The cutters 19 are fixedly mounted on the shaft 18 at each side of the machine and are formed of the vanes 20 of considerable length transversely of the machine and in cross section of spider shape, said vanes having the knives 21 in contact with the snow.-

he cutters 19 are rotated with the shaft 18 and the latter is driven by the chain 22 and sprockets 23 and 24, said sprockets being mounted on the shafts 18 and 4.

This driving mechanism turns the said cutters several hundreds of revolutions per minute, which has the efiect of driving great quantities of snow upwardly and for that reason the inclosed chutes 25 are provided, said chutes communicating with the flaring and substantial} semi-circular hoods 26 re inforced by the eavy la es 27, that extend on the shaft 4 and baflles to protect the machinery from the flying snow and also rigid supportsfor other parts ofthe mechanism.

The extension hood 28 is firmly secured by hinges 29 to the plates 27 on either side or one on each side if found convenient, and projects in an oblique direction outwardly in alinement with the main hood 26, and is separable therefrom, so that it may be transferred as stated aforesaid from one side to the other to coincidewith the work of the scraper plow as described hereinafter.

The extension hood 28 terminates at its upper end in a canopy top 30, and the outer hinged diflecting plate 31, this plate being hinged to said canopy top and extending thereacross and at each end terminating in the inwardl turned flanges 32.

. The extension hoo 28 forms the middle section of the delivery hood the top section 30 being hinged to said middle section and extending outwardl therefrom as a curved deflecting late for irecting the snow downwardly. T is pivotally suspended from the outer end of the top 30 and is inwardly turned at each end, forming the flanges 32, thereby provid ing a deflecting plate for continuing the fall of the snow from the deflecting top into .a'

convenient conveyance alongside the machine.

The hood' section 28 is operated by the cable 33 and chain 35, the links of said chain locking in the ring 36 slotted at 37 in the bracket 34.

It is more satisfactor with the extension hood to use a plow 43 ormed and mounted like a scraper. This scraper low 43 is rigid'with the frame 44. The rame 44 is formed with the flanges 45, which are secured to the bars 8 by the bolts 46, therefore the frame 44 is suspended by the bars 10 and adjusted by the reach bar 47, having the turnbuckle 48 and secured to an eye 49 from the machine body and to the eye bolt 50 secured in the frame 44. The brace 51 is secured across the V-sections of the frame 44. The scraper plow 43 is rigidly secured to one of the V-sections of the frame and ex tends therefrom to the opposite side of the machine, the extreme end being connected to the machine body by the chain 52. The strut 53 extends from a bolt 46 to the back of the scraper plow 43 and is rigidly secured thereto.

The plow 43 is finished off at its lower end in the steel knife 54 land extends across from the inner end of a cutter 19 in an angular direction to the far side of the machine in front of the other cutter, completely blockin the latter, so that all the snow is dii-ecte drives it into the chute above, whereby means of the centrifugal force and the .cur

he transverse deflecting plate 31 to the uncovered cutter and this rent of air created by the rapid revolution of the cutter, it is driven into the extension hood 28 and against the deflecting plate and.

so down into the accompanying vehicle to be transported to the dumping ground.

The rotary cutters on each side are preferably inclosed from the outer sides by the casings 55, into which the snow is guided and elevated by the cutters.

1 In the operation of the invention, the machine is drawn along the road to be cleared and the cutters set in motion. The scraper plow cuts the packed snow and directsall the snOW in its path into the path of a cutter and by means of the elevating vanes the snow is lifted into-the chutes, from which it reaches the hood and is flung off the edges of said hood against the canopy and deflectin plate and deposited.

Tarious changes may be made in the construction of this machine and in its mode of operation without departing from the s irit of the invention so long as they are within the scope of the claims.

What I claim is 1'. In a machine of the class described, a frame, means for gathering and elevating the snow, a chute and delivery hood, forming a discharge passage in sectional pieces the middle section being a removable extension hoodjoining a top forming a downward:l[y deflecting surface.
