SNOW-PLOW.

SPECIFICATION formingpart of Letters Patent No. 768,607, dated August 30, 19.04. I Application ilel April 4, 1904. Serial No. 201,607. (No model.)

T o all whom, it may concern:

Be it known that I, ARTHUR LABELLE, a subject of the King of Great-Britain, residing in the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Snow- Plows`; and I do hereby declare that the fol- A'lO lowing is av full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This invention relates to new and useful improvements in Asnow-plows adapted for use upon railroads for the-purpose of clearing .snow from the tracks thereof; and it consists in certain features of novelty in the construction and operation of theparts thereof, all as hereinafter more fully described, and specifically set forth in the claims.

The object of the invention is to produce a snow-plow of the character described which will be so constructed as to cut its way through an embankment of snow and present only such portion of the snow tothe wedge constituting the plow proper as will be necessary for clearing a given track, thus avoiding the packing of snow, which has been found to be an obstacle in the Way of the successful operation of snow-plows heretofore suggested.

Referring to the drawings, in which similar numerals of reference indicatecorresponding parts in all the views, Figure l is a side elevational view, partly broken away for the purpose of better showing details of construction. Fig. 2 is a plan view of the snowplow with the roof of the cabin thereof re manipulating the plow.

Referring to the drawings, l is a rear truck provided with supporting wheels 2 and a transverse bolster 3, adapted to support the platform 4, upon which platform is mounted the plow, which for convenience is hereinafter referred to as a wedge.7 At the forward end of the platform 4 are supporting-wheels 5, which are of less diameter than the wheels tors of the plow for the purpose of shelterj ing such operators from iiying material operated upon in the process of cutting through the snow.

Extending longitudinally of the car comprising the truck 1, bolster 3, platform 4, and supporting means is a sheathing 8, which extends from the truck-platform down to a point just slightly. removed from the said track-rails 6, so as toprevent the passage of snow laterally under the truck, which snow might have a tendency t'o dislodge the car from the track. Projecting slightly beyond the forward end 9 of the car and extending thence upwardly of the inclined iioor 10 are side walls 11, which are provided with vertical braces 12, transverse braces 13, and with the doors 14, connected to the side walls by means of the strap-hinges 15, as shown in the drawings, or by any other convenient securing means. -Projecting laterally from the walls 11, as best shown in Fig. 2, are socketed members 16, which are adapted to receive vertically-reciprocatory rods or bolts connected with the doors 14 for the purpose of securing the doors ina forward position, as shown by the dotted lines in Fig. 2, this position being desirable when the point 17 of the plow isswung toward the left o'r lower side, as shownv in the drawings. It will be noted that the door shown dotted in Fig. 2 is at the upper side or right-hand side as the apparatus advances; but when the plow is turned to that position it is preferred that the opposite door shall be open and the door at the righthand side shall be closed.

Suitably supported upon the platform 4 is a wedge shaped structure comprising the wings 18,.which converge toward the point 17. as best shown in Fig. 2.' The point 17 may comprise a casting, if desired, to .which is secured the said wings 18, the said casting affording a better resisting medium for the SiO IOO

impact of the snow and ice which will be projected thereagainst in the practical use of the apparatus. Connected with the inclined floor 10 at each side of said Hoor are sockets 19, into which sockets 19 pins passing through the lugs 2O on the point 17 may be projected for the purpose of securing the wedge in a position wherein the point will be held at either side of the said inclined floor 10. Between the wings 18, at the forward ends thereof and just behind the point 17, is a supporting-roller 21, upon which the said wedge will ride in its lateral movement. Extending transversely between the wings 18 within the lower portion thereof are brace-rods 22, which by means of angular extensions 23 are connected with said wings and which extend from thence to the plate 24, (shown in Figs. 3 and 4,) while a second transverse brace 25, also connected with said wings, extends to said plate 24, the braces 22 and 25 being connected with said plate at opposite sides of the eentral opening in said plate 24, upon which it turns. Below the plate 24 is a second plate 26, between which and said plate 24 frictionredueing balls 27 are provided, and the plate 24 is freely rotatable upon said plate 26 when desired. Connected with the upper portion of the said wings 18 are a plurality of bracerods 28 and 28, which are connected to a yoke 29 or which terminate in a yoke embracing the upper end of the fixed standard 30.

Vithin the cabin 7 is provided an ordinary brake-staff 31, supported within the bracket 32 and by means of the base-plate 33 between the flooring 101 and the superposed iiooring 34 within said housing. Upon the said brakestaff 31 is a small pinion 35, which meshes with a gear 36 upon the shaft 37, suitably supported between the flooring 10'1 and the superposed flooring 34, while on said shaft 37 is a sprocket 38, and engaging with said sprocket is a chain 39, which extends thence to the hangers 40, connected to the inner faces of the said wings 18. An ordinary hand-wheel, as 41, on the brake-staff 31 is adapted for rotating said brake-staff, pinion 35, gear 36, and actuating the chain 39 through the sprocket 38, and thereby swinging the wedge upon the pivot- plates 24 and 26. (Shown in Figs. 3 and 4.) rlhe standard 31, as will be noted, is of an increased diameter at its lower portion and is fixed in position by means of the plate 42, which is connected with the liooring 10 by means of bolts 43 projected through the timbers thereof. As the wedge must necessarily rock to some extent in its movement from the central point 44 (shown in Fig. 2) to the extreme sides of the car, owing to the inclination of the flooring 10, it is necessary that the plates 24 and 26 be so formed as to compensate for such rocking, and for this reason the openingI 45 in the plates 24 and 26 is larger at the top than at the bottom, and as the bracerods 22 and 25 are connected at opposite sides of the plate 24 at opposite sides of the pivotal opening45 itis evident that more or less rocking of the members 24 and 26 will result lrom the shifting of the wedge. This is compensated for by means of the plate 46, the upper face of which is curved approximately in an are of a circle struck from the yoke 29 at the upper end of said standard 30, the said plato 46 being a part of the plate 42 or connected therewith in such manner as to be lixed against movement thereon. Upon th\l advance lace ofthe cabin 7 are provided a plurality ol loops or eyes 48 at different distances from the sides thereof, and the hooks 49 are adapted to be connected with the lugs 50 upon the wings 18 and engage with said loops 48, or, il (clesired, anumber of hooks may be connected with said loops adapted to engage with eyelets ou the wings.

For the purpose of facilitating the lateral shifting of the wedge and to assist in supporting the rear thereof friction-rollers 5l are provided, one upon each inner side of the wings 18, as best shown in Fig. 3, the said rollers assisting in supporting the structure oi' said wedge.

The operation of my improved apparatus is as follows: An engineer othersuitable means being connected with the structure hereiubefore described it is propelled over the tracks 6 and the advance end thereof forced into the snow, which is cut by means of the said walls 11, so that only such portion thereof as is necessary to permit the passage of trains will be disturbed, a single track being' cleared only at one time. In driving the apparatus lorward snow will ride up the inclined iioor it), and if it is a single track the point 1T of the wedge may be supported centrally of the car; but if there is a track either at the right or left of the track on which the apparatus is being propelled the wedge will be turned by means of the hand-wheel 41 and its appurtenant connections to such position that the snow will impinge only one face of said wedge and be driven either to the right or 'lOO left, as may be desired, thereby cutting', lilting up, and throwing to one side or to both sides of the track the snow which it ls desired to remove without in any manner disturbing the surrounding bed of snow. As it has been found in practice that the snow becomes densely packed and has been almost impossible to remove in some instances, the cutting and separation from the main bed ol that portion which it is desired to remove is considered of great advantage, wherefore the cutting edges 52 of the side walls .Il are found to be of great utility, these cutting edges extending beyond the cara sullicient distance for practical use.

While l have shown in the accompanying drawings the preferred form of my invention, it will be understood that l do not limit myself to the precise form shown, l'or many of the detailsmay be changed in form or position'w'ithout affecting the operativeness o r utilityof `my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
