The object of. this invention is to facilitate the opening of railwayditches and the removal of the dirt therefrom.

The invention consists in the peculiar construction and arrangementof parts, as hereinafter fully set forth, and pointed out in the claims.

A represents a flat car, to the opposite sides of the rear end of which are hinged, by bolts 01'' other suitable detachable means, the rear ends of two bars, 13. The bars B are hinged at their forward ends to the outer forward corners of the frames 0, that carry the plows and the carriers. The bars B and their connections are made of sufficient strength to support the plows against the resistance of the ground. The frame 0 is formed of a baseframe and an outer side frame, meeting each other at an obtuse angle, as shown in Figs. 3 and 5, and firmly connected together.

To the inner side of the base of the frame 0 are attached, by spring-standards D or other suitable supports, narrow side boards, E, to keep the dirt in place upon the carriers while being carried back by the said carriers.

To the forward end of the frame G is attached the plow F, which is made angular in cross-section, as shown in Fig. 5, and with its point in line with the angle of the said frame 0. The cutting-edges or shears of the plows are made sharply inclined,and the outer shear is made wider than the outer partof the frame 0 to shear off the sides of cuts or banks. The inner side of the base-shear has a narrow inclined flange formed upon it to correspond with the inner side board, E, and is intended to serve as a guide to conduct the dirt to the carrier.

To the base of the frame 0 is pivoted a series of rollers, G, around which passes the endless belt H to form the base of the carrier. To the inclined outer side of the frame G is pivoted a series of rollers, I, around which passes an endless belt, J, to form the outer side of the carrier. The adjacent edges of the endless belts H J meet or nearly meet at the angle of the frame 0, and are covered by the central belt, K, which is made thick and has its side edges beveled to fit against the upper surfaces of the said belts H J. The inner side of the belt K is made of such a width as to fit the space between the adjacent edges of the belts H J. The outer part of the belt K projects a little beyond the beveled sides of the said belt, as shown in Figs. 3 and 4, to serve as flexible flanges. to pack the edges of the said belt and prevent dirt from working in between the belt K and the belts H J. The belt K, at the front and rear ends of the frame 0, passes around guide-rollers L, the faces of which are so formed that the inner side of the ICO * said belt K will exactly fit the said faces. The

rollers L are pivoted to supports attached to the frame 0.

To the outer ends of the rear rollers,GI, are attached beveled-gear wheels M, the teeth of which mesh into the teeth of the beveled-gear wheels N,attached to the opposite ends of the shaft 0, revolving in bearings attached to the frame 0, so that the side belt, J, will be carried by the movement of the base-belt, H.

To the journal of the inner end of the rear roller, G, is attached a crank-wheel, P, to the crank-pin of which is pivoted the jointed piston-rod of a small engine, Q, attached to the rear part of the inner side of the frame 0. The engine Q is designed to be supplied with steam through a flexible hose leading to the locomotive-boiler.

To the forward and rear parts of the frame 0 are attached the ends of bails R, to the middle parts of which are attached pulley-blocks S, the ropes T of which also pass around the pulleys of blocks U, suspended from the outer ends ofthe derrick-booms V. From the pulley-blocks U the ropesT pass around guide-pulleys W, pivoted to supports attached to the derrick-posts X. The ends of the ropes T are attached to windlass Y, pivoted to supports attached to the car A, and which are driven from a small engine, Z, attached to the car A and receiving steam from the locomotive-boiler, so that either or both ends of the frame 0 can be raised and lowered quickly to pass obstructions or give a desired depth to ditches and inclination to banks.

With the outer ends of the derrick-booms V are connected pulley-blocks a, the ropes b of V which pass around the pulleys of blocks 0, connected with the upper ends of the derrick-posts X. The ends of the ropes b are secured to the belaying cleats or cavils d, or other supports attached to the derrick-posts X, so that the booms V can be adjusted to swing the frames 0 outward or inward by means of the tackle a c I).

To the outer forward corner of the base of the frame (3 is hinged the outer end of a bar, 0, which is connected with the inner forward corner of the frame 0 by a hand-screw, f, swiveled to the said bar 0, and passing through nuts attached to the said corner of the frame 0, or to some suitable support connected with the said frame 0, so that the lateral inclination of the frame 0 can be regulated by turning the said screwf. The inner part of the bar 0 passes through the guide-block g, which moves up and down along a frame or post, h, attached to the forward corners of the car A, and has nuts 2' formed upon or attached to its ends to receive the screws j, having hearings in the said frame or post h, so that the said inner end of the bar 0 can be adjusted vertically by operating the screws To the upper ends of the screwsj are attached beveled-gear Wheels it, into the teeth of which mesh the teeth of the beveled-gear wheels Z, attached to the shaft m. The shaft m works in bearings attached tothe frame or post 7:, and to its end is attached a hand-wheel, a, for convenience in operating it to raise and lower the inner end of the bar 0, and thus regulate the lateral inclination of the frame 0.

Upon one side of the bar 0 are formed, or to it are attached, rack-teeth 0, into which mesh the teeth of the gear-wheel p, attached to the shaft q. The gear-wheel]; is made long and with a bulged or convexed face, as shown in- Fig. 6. The shaft q works in bearings attached to the frame or post it, and has a handwheel, 1', attached to its upper end for convenience in operating it to adjust the bar 0 longitudinally, and thus move the plow toward or from the track. The friction of the bar 0 when moved longitudinally is lessened by rollers 11, pivoted in recesses in the block 9, and which bear against the sides of the said bar 0, as shown in Fig. 6. With this construction, as the car A moves forward the plow F raises the dirt from the bottom of the ditch or cuts it from the face of a bank, and the belts H J K carry it back to the rear end of the frame 0, where it falls upon the endless belt 8, which passes around aseries of rollers, 13, pivoted to a frame, a. The frame a is designed to be supported by bails and tackle from derricks, in the same manner as the side carriers, as indicated in Figs. 2 and 5, so that its position can be regulated as circumstances may require. The carrier-belt s is driven by a small engine, to, to which steam is supplied from the boiler of the locomotive. The engine w is attached to the side of .the frame a, and its jointed piston-rod is connected with a crank-wheel attached to the inner roller, t. lVith this construction the carriers 8 t a can be swung around so as to deliver the dirt upon cars or, placed in the rear of the car A, with which the plows and carriers are connected, as shown in Fig. 10. In this case the cars a; are provided with a conveyer extending the entire length of the train. The conveycr is formed of slats y, the adjacent edges of which are beveled and overlap each other, as shown in Figs 14 and 15. The slats y are connected together at their centers by links a, the ends of which are contracted and interlock with each other, as shown in Figs. 15 and 16. The slatsg are connected near their ends by links 1,

the ends of which are contracted, and are connected by short links 2, as shown in Figs. 16 and 17. The contracted end parts of the links a 1 are placed in recesses in the beveled edges of the slats y, as shown in Fig. 15. The couplings, in connection with the beveled edges of the slats 3 allow the said slats y to have alittle play upon each other when the cars are passing around curves. It the conveyor, at a distance apart equal to the length of a car and the distance between two adjacent cars, the end couplings, 1 2, are omitted, and the adjacent edges of the slats 3 are beveled from the center toward each end, as shown in Figs. 10

and 11, to give the conveyer the lateral play necessary in passing around curves.

When thetrain of cars is'to be drawn from place to place the conveyer should be so adjusted that the single slat-couplings will be directly, over the ear-couplings, so that the train can pass around curves without strainin g the conveyer.

Each link Z1 is made in two equalparts, the division being made in the center of its side bars. The adjacent endsof the parts of the links have right-andrleft screw-threads out upon them to receive the right-and-left nuts 3, so that the wear can be taken up by turning the said nuts.

To the inner side of eachend of each slat 3 is attached a pairot hangers, 4, to andbetween tthe lower ends of whichis pivoted a small wheel, 5, and to the center of each slat y is attached a pair of hangers, 6, to and between the lower ends of which is pivoted the wheel 7. The wheels 7 are made larger than the wheels 5, and have their faces grooved and provided with side flanges to fit upon the corresponding-shaped top of a bar, 8, to prevent the conveyer from having a lateral movement.

The side wheels, 5, roll upon the tops of the bars 9. The bars 8 and 9 are secured to crossbars 10, the ends of which are attached to the posts 11 at a little distance from their upper ends. The lower ends of the posts 11 are attached to the cars or. The bar Sis placed at a little lower level than the bars 9 on account of the greater size of the wheels 7, and the bars 8 9 and posts 11 are strengthened in position by truss-rods 12, which pass through the posts 11 and bars 9 and beneath the bar 8,

as shown in Fig. 12. The lower part of the conveyer slides upon rollers pivoted close to the decks of the cars or, and is kept from lateral movement by cleats 13, attached to the decks of the cars. At the front end of the first car of the train and the rear end of the last car the wheels '5 pass around wheels 14,

attached to shafts 15, which are pivoted to posts 11.

To the middle part of the rear shaft, 15, are attached two rag-wheels, 16, at such a distance apart as to receive between them the guidewheels 7. The teeth, arms, or projections of the wheels 16 are so formed as to engage with the hangers 6, to which the said wheels 7 are pivoted, so that thelupper part of the endless conveyer willbe drawn toward the rear end of a the train by the revolution of the shaft 15.

To one end of the shaft 15 is attached a crank-wheel, 17, to the crank-pin of which is pivoted the jointed pistonrod of an engine, 18, attached to the side of a car, an, as shown in Fig. 10. The engine 18 is supplied with steam through aflexible pipe, 19, from a boiler, 20, placed upon a tool-car, 21, coupled to the rear car, 00.

To the rear end of the rear car, as, is attached a V-shaped guide or chute, 22, to guide the dirt discharged from the endless conveyers at the rear end of the rear car to the sides of the track. With this construction, as the train moves forward the plows F raise the dirt. The belts H J K carry it back and discharge it upon theendless apron s, by which it is conveyed to the conveyer 3 As the conveyor y is loaded it is carried back by the engine 18 until that part of the conveyer over each car in the train is loaded. When the conveyer is loaded the plows F are raised from the ground, the conveyery is adjusted to bring the beveled cleats over the car-couplings, and the train is then drawn to the place where the filling in is to be done. The engine 18 is then started and the dirt is discharged from the rear end of the rear car,'w.
