IVM. CHADVICK AND S. J. B. ANDERSON, OF TERRE HAUTE, INDIANA.

RAILROAD DITCI-IING-JNIACHNE.

Specification of Letters Patent No.

To all whom i may concern:

Be 1t known that we, WM. CHADwIoK and i S. J. B. ANDERSON, both of Terre Haute,

in the county of Vigo and State of Indiana, have invented a new and useful Railroad Ditching-Machine; and we do hereby declare that the same is described and represented in the following specification and drawings.

To enable others skilled in the art to make and use our invention we will proceed to describe its construction and operation referring to the drawings in which the same letters indicate like parts in each of the figures.

Figure l, is an elevation of one side of the machine. Fig. 2, is a plan of the machine, the top frame on the right hand half being omitted to show the parts below more clearly.

The nature of our invention consists in a series of levers arranged upon a railroad car, and extending over the sides and arranged to hold and operate scoops or scrapers, to take the earth from the sides of the rail track to make a ditch by the side of the railroad on which the car runs that carries the levers. Also in making the scoops or Scrapers so that they can be worked either end forward, the same side up to be filled. Also in making a vibrating mouth piece to the scrapers that can be worked, so as to aid in loading the scraper.

In the accompanying drawings A, is the body or top of a railroad car mounted on the trucks B, B, so as to travel, or run on a rail road of ordinary construction. C, C, are two bars-fastened on the top of each end of the car, into which bars the posts D, D, are fastened to support the top frame E., as shown in the drawing. There are ten llevers numbered from l, to l0, fastened to the car A, with eye bolts so as to vibrate freely the ends of tive of these levers project from one side of the car and the ends of the other five project from the opposite side as shown in Fig. 2. The ditching scoops F, F, are hung to the levers 7, and 9, by chains as shown in Fig. l, and the scoop F, is connected to the levers 6, and 8, by iron rods or bails G, G, and the scoop F', to the levers 8, and 10, by chains Gr', G. The levers 2, 4, 7, and 9, are provided with pulleys H, H, for the ropes I, I, which are fastened to the top frame E, and pass under the pulleys H, H, on the levers to (raise them) and over 21,942, dated November 2, 1858.

pulleys in the top frame E, and are fastened to the rollers J, J, which are arranged to turn in hangers K, K, fastened to the top frame E. The rollers J, J, have the large pulleys M, fastened to them; to which pulleys the ropes N, N, are fastened; the other or opposite ends of these ropes are fastened to the shafts 0, C, which shafts are provided with cranks I), l), and are arranged to turn in standards Q., Q, from the frames l, R, fastened to the body A. The shafts O, O, are provided with ratchet wheels S, S, and pawls T, T that are arranged to vibrate, so that when they are in the position shown at U, they catch the teeth of the wheels S, and hold it; but by drawing them into a perpendicular position, right opposite the standard Q, the ratchet wheel will be released and may be turned back to unwind the rope on the shaft O, and let down the scoop.

The levers l, 3, 5, 6, 8, and 10, have ropes V, V, fastened to them near their outer ends which ropes pass over pulleys in the top frame E, so as to be pulled by the attendant, and raise the end of the scoop attached to the lever, and depress the opposite end, so that it will catch the earth, as the car is drawn along on the road, and hold the earth so caught, until the car arrives where the earth taken up by the scoop is to be deposited; when the scoop may be emptied by raising it so near perpendicular that the earth will slip out.

The scoops F, and F', are made in the form shown in the drawing, that is with curved bottoms and both ends alike, so that they will catch the .earth with the same facility, when the car moves them in either direction.

It is a great advantage to make the scoops, so that they can be filled at either end, as one end of the scoops can be filled when moving in one direction and the other end when moving in the opposite direction, and in this way both ends can be filled with facility with a much larger load than if they were filled at one end only.

rlhe bars C, C, frames R, R, and bars W, lV, are so arranged on the body A, as to prevent the levers from swinging sidewise when working the scoops.

To use'this machine the operator adjusts the scoops to the desired height by turning the cranks P, l?, then by pulling the ropes V, V, to raise one end of the scoops and los depress the other end, to catch the earth and load one end of the scoop, and while doing so, he can turn the crank P, and lower the scoop while it is being lilled and after y it is filled 'raise it again to carry the load to the place of deposit; and when it arrives there one end may be raised without stopping the car so as to empty and deposit the load as may be desired.

Should it bc desirable to do so one of the scoops may be removed and one or more plows put in its place to plow the earth and prepare it for the scoop; or instead of the plows chains may be applied to take up stones stumps or other articles that require to be removed from the side of the road.

Fig. 3, is a plan and elevation of a scoop with a vibrating mouth piece X, hinged to the bottom of the scoop. This mouth piece has perpendicular sides to which the bail Y, is attached, and there is a slot Z in one side for a bolt which limits the vibrations of the mouth piece. The arm Z is fastened to one side of the mouth piece to enable the operator to work it up and down as he desires.

Ve believe we have described and represented our invention, so as to enable any person skilled in the art to make and use it.

We will now state what we claim and desire to secure by Letters Patent to wit:

l. 7e claim the levers 2, t, 7 and 9, arranged on a car substantially as described for holding the scoops at the side of the car and for adjusting or raising and lowering them as required.

2. 7e also claim the levers l, 3, 5, 6, 8 and 10, arranged on a railroad car as described, for operating the scoops so as to catch their load of earth and for dumping them as required.

8. `We also claim the scoops F F made as described so that they may be worked either end forward the same side up to be lilled.

4. `We claim the vibrating mouth piece X, hinged to the scoop so as to be vibrated substantially as described.
