ICE OR SNOW PLOW FOR RAILROAD-TRACKS.

SPECIFICATION forming part Of Letters Patent N0. 405,039, dated June 11, 1889.

Application filed May 2, 1388. Serial No. 272,552. (No model.)

T0 at whom it may concern.-

Be it known that I, EDWARD LESLIE, of Orangeville, in the county of Dufferin, Prov ince of Ontario, and Dominion of Canada, have invented a new and Improved Ice or Snow Plow Flanger for Railroad-Tracks, of which the following is a full, clear, and exact description.

The invention relates toice or snowplows such as shown and described in Letters Patent No. 380,042, granted 'to me under date of March 27, 1888.

The object of the invention is to design an effective ice or snow plow, which will loosen any hardened snow or ice immediately next to the track, and a flanger that will remove the snow and ice in proximity to the inside rail and discharge the same at a sufficient distance from the track to prevent it from falling back.

The invention consists in an independent raising and lowering mechanism whereby the preceding snow or ice plow or the following flan ger may be put into operation either separately or to co-operate, as desired. 1

The invention further consists in providing the snow or ice plow mechanism and the flanger mechanism with an independent device, whereby the shock or strain consequent upon either the snow or ice plow or the flanger striking an obstructionsuch as a switch-which invariably results in either tearing out the obstruction or demolishing the snow plow or flanger, or both, will break, shear off, or tear out such device, thus permitting the obstruction and the above-mentioned mechanism to remain unharmed.

The invention also consists of certain parts and details and combinations of'the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the'accompanying drawings, formingapart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is aperspective view of the improvement as applied. Fig. 2 is a like view of the ice-plows and rail-scrapers. Fig. 3 is an enlarged sectional end elevation of part of the same on the line at a; of Fig. 2, and Fig. 4 is a perspective view of the fiangers and their immediate connections.

The truck A, of any approved construction, is provided with a frame B, having at its front upper end a cross-beam B, carrying the bear ings B in which is journaled the transverse shaft 0, provided with the crank-arms O, pivotally connected with the Vertical posts D D, secured to each other by a transverse brace D so as to form a frame D, carrying the ice-plows E and the scrapers F.

The frame D rests with its rear end against the front ends of the longitudinal beams B of the truck-frame, and the front ends of the said beams B are connected with each other by the brace B and form a guide for the vertically-sliding frame D. r r On the lower end of each post D is held a plate G, having a beveled rear edge G, resting against a pin 13 secured to the respective longitudinal beam B 'of the truck-frame 13. Next to this plate G is placed the ice-plow E, which extends below the plate G and the post D, and is held close to the inside of the respective track-rail H, and when in its lowermost position extends with its bottom end to within a short distance of the railroad-"ties H.

On the outer face of each plow E is held a scraper F, formed of an Lshaped plate, and extending,with its arm F, across the top of the re spective rail H when the post'D is in its lowermost position. The arm F of the scraper F is slightly inclined toward the rear, so as to facilitate the removing of the snow or ice scraped up by the lower edge of the said arm F. By means of the said inclined face G of the plow G and the pin B the ice-plowE and the scraper F are prevented from coming in contact with the tread of the truck-wheels.

The plate G and the plow E are secured to the lower end of the respective post D by a heavy bolt E, and the scraper F is secured by the smaller bolts E and E to the plow E;

but the bolt E passes through the plow E, and the plate G and is held into the post D, while the other bolt E is shorter, and only screws into the plowE without passing into the plate G or the post D, as shown in Fig. 3. Thus when the frame D is in its lowermost position and the apparatus is in operation and the plows E strike against a switch-rail or other obstruction in the track, then the force of forward movement of the truck A causes the shearing off of the small bolt E and the Ice plow E, scraper F, and plate G swing rearwardly and upwardly, turning on the heavy bolt E as a pivot. A breaking of the switchrails is thus prevented. The bolt E is then replaced by a new one to secure the several pieces together, as above described.

On the rear upper end of the frame B is held a transverse beam B, provided with hearings in which is journaled a transverse shaft I, having crank-arms I pivotally connected with the upright posts J, connected with each other near their lower ends by the transverse beam J so as to form the frame J the latter supports at the ends of the beam J the flangers K K, held at an angle to the said beams and formed like a scoop, with the outer open ends extending rearward. The inner closed end of each flanger K is provided with a downward projection K, extending below the top of the respective rail ll, so as to gather up the snow and ice between the rails II and loosened by the plows E, before mentioned. The outer ends of the two flan gers K are connected with each other at their back by a brace K. The outer ends of the flangers K extend a considerable distance beyond the outside of the rails H, so as to deliver the snow and ice a suitable distance to each side of the track. On the inner edge of the trans verse beam J 2 are held the vertical guide plates J against which rest the upwardlyturned ends B of the longitudinal beams B secured to the truck-frame.

To the inner ends of the flangers K K are secured the brackets K K connected with one end of the chains L and L respectively, extending forward and passing over the lower curved ends of the vertical rods L and L respectively, held in suitable keepers 011 the truck-frame B, as is plainly shown in Fig. at. The other ends of the chains L and L extend inwardly toward each other, and are secured to the ends of the plate N, pivoted in its middle to the vertical rod N, held in suitable keepers on the front of the middle beam of the truck frame B, between the rods L and L Near the outer end of the two transverse shafts C and I are formed drums O and 0, respectively, on which are secured the chains P and P, respectively, passing rearward and over a drum Q, 011 which they are secured. This drum Q is mounted to rotate in suitable bearings formed on the car R in the rear of the truck A, and the drum is operated by a chain Q, connecting the said drum with one end of a piston-rod Q supporting a piston working in the cylinder Q operated by steam or air and under the control of the engineer. On the outer ends of each of the two shafts C and I is also secured an arm S and S, respectively, held inclined to each other and connected with the chains T and T, secured to the lower end of the vertical lever U, fulcrumed in the middle of the truck A. A short chain V is secured to the other end of the arm S, and is connected with the frame 13, serving to prevent the arm S and its shaft I and the flangers K returning to their former position after the flangers are raised.

The operation is as follows: IVhen the ma chine is in the position shown in Fig. 1. and the truck A is pushed forward by suitable means, then the plows E loosen the ice next to the inside of the rails II, so as to form a clear space for the flanges of the following car-wheels to prevent a derailing of the cars. The scrapers F, held on top of the rails ll, remove all snow and ice from the same, so as to clear the rails for the tread of the following car-wheels. The tlangers K K at the rear of the truck A gather up a large amount of snow and ice located between the rails and at their outside, and at the forward motion of the truck the snow and ice pass through the open ends of the scoop-shaped scrapers and are delivered a suitable distance beyond the sides of the track. \Vhen the plows E strike an obstruction in the track, the bolts E are sheared off, as above described, and the plows are thrown upward and rearward above the rails II. The truck A is moved beyond the obstruction, the bolts are replaced by new ones, and then the apparatus is again moved forward, as above described. When the flangers K strike an obstruction, the plate N, connected by the chains L L with the said Hangers, is broken,and the latter are free to swing rearwardly, turning with their frame J on the crank-arms I of the shaft I. WVhen the obstruction is removed or passed, then the plate N is replaced by a new one. The plate N is purposely so made that when the flangers or either of them meet an abnormal obstruction the plate N will break about the shaft N, thus leaving both flangers free and avoiding any twist being thrown upon the frame-work of the flanger, which would be the case were one Hanger free and the other held fast. I purposely make the chains L L and their connections with the Y plate and flangers much stronger than the plate N where the same is pierced by the shaft N, and in this way when an obstruction is metit results in freeing both flangers.

hen the operator desires to raise theplows E and scrapers F, he throws the lever U forward in the direction of the arrow a, whereby the chain T pulls on the arm S, thereby turning the shaft 0, so that the crank-arms C swing upward and raise the frame D, carrying the plows and scrapers. The latter are thus raised above the track-rails H, and can clear switch-rails or frogs located between the rails. hen the obstruction is passed, the lever U is moved to a vertical position, whereby the frame D by its own weight slides downward to its former position. The flangers K K are raised above the track by moving the lever U in the reverse inverse direction of the arrow a, so that the chain T pulling on the arm S turns the shaft I, and the latter, by the crank-arms I, raises the frame J and the flanger K connected with the said IIO ITS

frame. By moving the'lever U forward or backward I am enabled to throw either the plows E. and scrapers F or the flangers K upward out of contact with the rails and hold them in this position, so that only the plows E and scrapers F or the Hangers K, as desired, are'at work.

WVhen the operator desires to raise the plows, scrapers, and flangers simultaneously, then steam or air is admitted to the cylinder Q so as to raise its piston and piston-rod Q whereby the drum Q is turned and the chains P and P are wound up on the said drum Q. As the chains P and P are connected with the shafts O and I, the latter are consequently turned and raise the frames D and J in a similar manner to that above described in reference to the lever U.

It will be seen that the several devices are fully under the control of the operator, and if the plows E or flangers K should strike an unseen obstruction they operate automatically and without injuring or destroying the obstruction. Instead of using crank-arms O and I on the shafts O and I, I may employ similar devicessuch as cams, levers, or eccentricsfor raising the frames D and J.

It will be seen that by supporting the frames D and J from the truck-frame, instead of the car-body, I am enabled to clear the rails perfectly on curves, as the said frames are not affected by the swaying of the carbody or the lateral motion of the car-springs when the car passes over the curve.

One of the objects of my present invention is to support an ice-plow, scraper, and flanger solely from the truck, and in such a way that the devices do not receive any motion from the movement of the car-body when the same may move in relation to the truck.

My invention is illustrated and is best carried out with the truck-frame and journalboxes for the wheels so arranged that the frame and journalboxes always move together; but it can be used on either form of trucks, although on trucks where there is a movement between the frame and journalboxes as close an adjustment of the scrapers and flangers to the top of the rail cannot be had as can be made in the case where the truck is so constructed that there is practically no movement between the frame and the journal-boxes.
