SNOW-PLOW.

SPECIPICATIQN forming part: of Letters Patent No. 309,275, dated December 16, 1884. Application filed April 19, 1884. (No model.)

the locomotiveengine; and the objects of my improvements are, first, to provide a system of cutters fastened to and forming a part of the plow-frame, so that a solid block of snow may be removed; second, to arrange for the raising and lowering of the point of the plow,

and by the use of a hinge or hinges to be able,

when desired, to place the plow upon the same horizontal level with the truck platform; third, to afforda method of locking the plow in a firm position to the truck-platform after the same has been loaded; fourth, to permit the withdrawal of the material upon the load ed plow and furnish means for dumping the same upon either side of the track at any de sired point. I attain these objects by the mechanism illustrated in the accompanying drawings, in which" Figure 1 is atop plan View. Fig. 2is a side view with the plow upon a horizontal level with the truck-platform. Fig. 3 is a side View with the point of the plow lowered, ready for commencing work. Fig. t is a side view of the plow upon a longitudinal level with the truck-platform, but tilted laterally for the purpose of dumping the snow at the side of the track.

Similar letters refer to similar parts th roughout the several views.

A represents the platform, which in practice is mounted upon car-trucks that by preference have small wheels in front and larger and bolted one to each of the cross-beams A. in such manner that the push'bar D is firmly held from lateral displacement,yet free to turn within the bearings formed by the joint union of the semicircular straps and cross-beams.

E is a bolster firmly secured to the push-bar near its rear end, and E is still another bolster firmly secured to and made apart of the plow proper. This bolster E has a cylindrical bearing in the center, around which passes a semicircular strap, a, and by which the bolster is secured and made to turn within the concave bearing formed upon the top of the push-bar.

F are longitudinal plow-beamsbeveled upon the under side at their front ends, so that when will be presented to the snow-drift.

F is a cross-beam near the forward end, and

F is the, rear crossbar by which the plowbeams are firmly united.

In practice the entire frame-work that comes in contact with the snow is covered with metal or other suitable material, and by which the floor of the plow is formed.

Midway the length of the plow-beams, and upon the under side of the same, is firmly secured the bolster E, thus fastening the plow to the push-bar in such manner that it can be rocked upon the same in the direction of its length.

G is a stop placed between the beams F,

and against which (in the act of plowing) the forward end of the push-bar rests. H are vertical posts, mortised one intocach of the outside plow-beams near their rear ends, and H are braces placed at an angle to the posts H, and stepped into the beams F, so as to make the back end of the plow secure.

I are beams running parallel with beams F, but above the same.

I is a cross-beam uniting the rear ends of beams I.

. J are braces, arched for strength, crossing each other diagonally and firmly bolted to the beams I, for the purpose of keepingthis upper frame in a rigid position.

K are metallic cutters secured to the forward ends of both the upper and lower frames of the plow. The upper ends of these cutters fall back, so as to make an oblique cut when the plow is forced into the snow-drift.

K is also a cutter running across and unit- ICO ing the front ends of the beams I. These knives or cutters act as supporting-bars for securing the front end of the upper framework in a firm position.

In order that the plow may be prepared for the shock incident to the end thrust when encountering a heavy body of snow, gains are made in the beams F, as at f, so that the shoulder of the gain will impinge against the forward end of the sills of the truck-platform. The hinged posts B are also notched, as at b, so that a shoulder is formed, which extends under the rear end of .the plow when ready for work, and holding it in the position shown in Fig. 3. Other notches are made in these hinged posts, as at b, and by means of which the plow is held upon a horizontal level with the truck-platform, as shown in Fig. 2. If desired, a lever, wheel, rack, and pinion, or any other well -known device may be employed to facilitate the tilting of the loaded plow when in the act of discharging the snow. Any well known mechanical device may also be used to raise and lower the plow, although, when properly balanced, it is believed that any mechanism will not be necessary for this purpose. Should it become necessary, in order to carry a heavier load than the open plow will admit of, doors or other appliances may be used upon the sides, so as to inclose the whole or a part of the side opening until the time for dumping.

The operation is essentially as follows: After placing the car-platform upon the necessary trucks, and having the plow mounted thereupon, as hereinbefore described, the coupling is in any well-known manner made with the locomotive, the plow being forward of the same, with the rear elevated, so as to cause the forward end to dip, and after being secured in this inclined position by the use of the hinged supporting-posts the run is made, the plow forcibly thrust into the snow-drift, the knives, while materially lessening the friction, quickly separates the mass to be removed from' the embankment, and as the impetus given promptly fills the plow, therear end can be lowered, and when the plow is secured from rocking the whole can be withdrawn,(if the bank is too heavy to drive through,) when by the tilting of the plow the snow can be deposited upon the side of the road out of the way, and the operation repeateduntil the passage-way is cleared, all of which will be readily understood without further description.

Having now described my invention, what I claim as new, and desire to secure by Iletters Patent, is

1.- The combination of the cutters, the plowbeams,the upper longitudinal beams,the pushbar, the stop against which the push bar rests, and the truck-platform, arranged and operating substantially as described.

2. The combination of the push-bar, the plow-beams, the cross-bolster secured to the same, the hinged connection between the bolster and push-bar, and the hinged plow-supporting posts at the rear end of the plow, all arranged and operating substantially as described.

3. The combination of the plow-beams, the push-bar, the bolsters E E, the latter hinged to the plow-beam, the truck-platform, and the centrally-notched supporting-posts at the'rear end of the plow, all arranged and operating substantially as described.

4. The combination of the truck-platform, the plow-beams, the cross-supports A, the push-bar mounted upon the cross-supports, and the bolsters E E, all arranged and operating substantially as described.

5. The beveled plow-beam having the notches f, the posts H, braces H, beams I, cross-beams I, knife-bar K, and braces J, all arranged-and operating substantially as described.
