SPECIFICATION forming part of Letters Patent No. 515,678, dated February 2?, 1894. Application filed May 22, 1393- Serial No. 475,020. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM Lnsrnn HAR- VEY, of Stanberry, in the county of Gentry and State of Missouri, have invented a new and Improved Ditching-Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved ditching machine, which is simple and durable in construction, very effective in operation, and more especially designed for use on railroads to form aditch on one or both sides of the road bed.

The invention consists principally of a scraper arranged on the side of the platform car and connected at its ends with draft beams held on the car, transverse levers pivotally-connected with the scraper and with transverse sliding blocks on the car, and a hoisting device connected with the said levers and located on the car, as hereinafter described and claimed.

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

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

Figure 1 is a plan view of the improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a cross section of the same on the line 3-3 of Fig. 2. Fig. 4: is a perspective view of the scraper; and Fig. 5 is a like view of the spreader. I

The improved ditching machine is mounted on a platform car A, of any approved construction, and on the sides of which are ar ranged the scrapers B alike in construction, each provided with a bottom B, and the two shown in the drawings.

The front ends of the sides B and B of each of the scrapers B are connected by the chains G with a draft bar 0 connected by a chain (3 with a draft beam D pivoted at D on top of the platform car A, and held in place by a brace D also pivoted on the car, to permit of swinging the said draft beam inward when not in use. The rear ends of the sides B and B of each of the scrapers B are connected by the chains 0 with a draft bar 0 connected by a chain 0 with the rear draft beam D similar in construction to the beam D and pivoted on the platform car and held in place by a pivoted brace D as plainly shown in the drawings.

The inner side 33 of each of the scrapers B is provided at its upper edge with a pivoted wing B so as to prevent the accumulating dirt from falling onto the railroad track. This side B of each scraper is pivotally-connected with a link E formed at its upper end with a row of apertures one of which is adapted to be engaged by a pin E, held in an arm 13. pivoted on top of the platform car near the middle thereof, as plainly shown in the drawings. The link E serves to guide the scraper and also assists in regulating the depth the scraper is to go down into the ditch.

The outer side B is provided at its upper edge with a pivoted wing 13 adapted to give slope to the side of the ditch to be formed, the said wing B being provided with curved guide arms B extending inwardly toward the middie of the wingso as to guide incoming dirt down into the scraper B. lhis wing 13 is pivotall -connected by a link B with a shaft B? arranged longitudinally and held in pivoted .U shaped arms B -secured to the sides of the scraper B near the ends thereof, as plainly shown in the drawings.

The shaft B of each of the scrapers is con--.

nected with levers F pivoted on swivel blocks- F pivoted on transversely-sliding blocks F fitted to slide on guideways F arranged trans versely on top of the platform car A. The front lever F of each scraper B is provided with a clevis G on which is secured one end of a rope G extending upwardly and inwardly to wind upon a drum H, mounted to rotate loosely on a longitudinally extending shaft I, journaled in suitable hearings in the-upper ends of the standards A erected on the platform car A.

The rear levers F of the scrapers B are provided with cleviscs G on which are secured the ends of a rope G also extending upwardly and inwardly to wind on a drum H mounted to rotate loosely on the longitudinal shaft I, previously mentioned. This shaft I carries a sprocket wheel I, over which passes a sprocket chain 1 also passing over a sprocket wheel I secured on a shaft 1 extending longitudinally, and mounted to turn in suitable bearings secured to the top of the platform car A. The outer end of this shaft 1 carries a bevel gear wheel 1 in mesh with a bevel gear wheel I, secured on a transversely-extending main driving shaft J, of a pair of engines J of any approved construction and deriving theirsupply of steam from a boiler J located between the engines on the rear end of the platform car A. If desired the boiler J may be dispensed with, and the engines supplied with steam from the locomotive used for hauling the car over the railroad track.

On the drums H and H are formed clutch teeth H and H respectively, adapted to be engaged by the clutches K and K respectively, mounted to slide on and to turn with the shaft l, so that when the said clutches are in mesh with the clutch teeth on said drums,

the latter are rotated on rotating the shaft 1 from the main driving shaft J, of the pair of engines. The clutches K and K are adapted to be shifted longitudinally on the shaft 1, and for this purpose the said clutches are engaged by clutch bands K and K respectively, connected by links K and K respectively, with hand levers K and K respectively, fulcrumed on the front and rear standards A and under the control of the operator. By this arrangement each of the drums I-Iv and H can be independently controlled by the operator shifting the corresponding lever K or K to cause the respective drum to rotate or not, as desired.

On the inner ends of the drums H and H are secured the ratchet wheels 11 and H respectively, adapted to be engaged by sliding pawls L and L respectively, mounted to slide on the innermost standards A, as plainly shown in Figs. 1 and 2. The lower ends of the sliding pawls Land L are connected with the crank arms N and N respectively, formed on the ends of longitudinally-extending shafts N and N respectively, of which the former is provided at its outer end with a second crank arm N and the other shaft N is provided at its outer end with a hand lever N under the control of the operator. The crank arm N of the shaft N is connected by alink N with a hand lever N fulcrumed on one of the standards A, and under the control of the operator.

On the hub of the sprocket wheel I is secured or formed a brake wheel 0 engaged by a brake band 0 secured at one end at O, to a stud projecting from one of the innermost standards A. The other end of the brake band Ois connected with a crank arm 0 held on the inner end of a longitudinallyextending shaft 0 journ aled in suitable bearings on the top of the platform car A, the outer end of the said shaft being provided with a handle 0 under the control of the operator.

The operation is as follows: When the several parts are in the position as shown in Figs. 1, 2 and 3, and theplatform carAis pushed forward by a locomotive, then the scrapers B on the sides of the platform car A pass into the ground with their front ends, thus taking up the dirt which fills onto the top of the scrapers. Usually the platform car A is pushed forward a distance corresponding to about the length of the scrapers, so that the latter are filled with a considerable amount of dirt. When this has been done, the operator sets the engines J in motion, and connects the hoisting drums .H and H with the shaft I, so that the rotary motion of the latter rotates the said drums to Wind up the ropes G and G whereby an upward swinging motion is given to the levers F, which thus raise the scrapers B off the ground; the car is'then drawn by the locomotive to the place of dumping, and then one of the drums H or H is-released from its respective clutch, and at the same time the corresponding pawl L or L is withdrawn, to permit a free revolving ofthe drum to unwind the corresponding rope thereon. By this arrangement the levers connecting with the unwinding rope swing downward, while the other levers remain in an uppermost position, so that the scrapers B assume an inclined position, and thus automatically discharge the dirt on the said. scrapers. When this has been accomplished, the lowered end of the scraper is again raised by connecting the corresponding clutch with the drum, so that the rotary motion given to the shaft Lwinds up the rope to bring the scraper back to its ing this second revolving of the shaft I the other drum is disconnected from its respective clutch and held in a locked position, by the corresponding sliding pawll' or L. The car is then returned to the ditch, the scrapers are lowered into the former place, andthen the car pushed forward, and the, above described operation is repeated.

It will be seen that by the arrangement described, the scrapers B can be raised after being loaded and moved inwardly and rested on the top of the car on opposite sides of the main shaft, so as to permit of pushing the car through narrow places, bridges and the like, without danger of the scrapers striking walls of bridges and similar structures. It is further understood that when the levers F commence to swing upward, the bars E guide the upward movement of the scrapers, and the blocks F connected with the levers do not commence to slide inward until after the bars E have passed a vertical position.

As illustrated in Fig. 5, a spreader P may be attached to the levers F for the purpose of spreading the dirt on the place of dumping, it being understood that this spreader then takes the place of the scrapers. Each of the spreaders is provided with an inclinedside wall P, and a bottom P as shown in 5. The inner end of the inclined side Wall P is normal position, it being understood thatd ur- IIO , provided with a clevis P for connection with the draft beam. The upper portion of the side wall P is curved outward, as shown at P so as to form a kind of pocket and prevent the dirt from falling inward over the upper edge of the wall P. On thetop of the said inclined wall P is journaled a shaft P for connection with the levers F in a manner similar to the connection of the scrapers with the said levers. When this spreader is passed over the fill, the inclined wall P pushes the accummulated dirtoutward, so as to even the same.

Having thus fully described my invention, I claim as new and desire to secure by Letter Patent l.
