APPARATUS FOR RAISING AND MOVING EARTH.

SPECIFICATION forming part of Letters Patent No. 399,970, dated March 19, 1889.

Application filed April 2, 1888. Serial No. 269,235. (No model.)

To all whom it may concern:

Be it known that I, HOWARD ADAMS OAR- SON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Apparatus for Raising and Moving Earth, of which the following is a specification.

My invention relates to that class of apparatus employed for raising and moving earth and other material in which buckets are filled at the place from which it is desired to move the material, and then raised and caused to travel to the place where it is desired to dump their load; and the invention consists in certain details of construction, hereinafter fully described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side elevation of an apparatus for raising and moving earth em bodying my invention. Fig. 2 is a side view of a portion of the .track and gear, drawn on. a larger scale. Fig. 3 is a plan or top view of the same. Fig. 4 is an end view of the same. Fig. 5 is a vertical transverse section taken on line a; .90 of Fig. 2.

The frame of the apparatus consists of standards A A, provided at their lower ends with small wheels B, that run on a track, 0. The standards are connected together at their lower ends by stringers 1 and are connected across the top by cross-beams E, that carry two longitudinal stringers, F, and to the crossbeams E is hung by-bolts G abeam, H, which forms a track for the travelers to run upon; or, if desired, the track may be hung from the stringers F. The travelers each consist of four hangers, I, (two on each side of the track,) to the upper end of which are secured short spindles, upon which are mounted wheel J, and to the lower end of the hangers I are secured bearings K, in which are mounted short pieces of shaft L, which are connected together by short pieces of shafting L and universal joints M, thus making one continuous shaft, but with joints, so that it can pass round curves. To each of the shafts L and between the bearing K, I rigidly secure drums N, provided on each side with a flange and a ratchetwheel, P, and to the inner side of the bearings K, I secure pawls Q, (see Fig. 5,) which take into the teeth'of the ratchet-wheels P. To each of the drums N is secured one end of a rope, R, and to the other end of 'the rope is usually secured a bucket or receptacle, S. On one end of the shaftL is mounted a bevel gearwheel, T, that is in gear with a bevel gearwheel, U, mounted upon a short cross-shaft, V, that runs in bearings W, hung from the track H by means of hangersI and wheels J, the two wheels T U being held in contact with each other by means of straps or stays X, secured to the bearings K K at one end, the shaft V passing through the other end, as shown. Upon the shaft V is also mounted the main winding-drum Y, to which the end of the winding-rope Z is secured, the other end being connected to a drum, a, that is driven by a small engine, I). The shaft V is provided with sleeves or ring-buffers m in that part that comes into contact with the counterbuifers, as hereinafter described.

To the stringers F are secured counter-b u ifers (Z by means of bolts 6, upon which they are free to turn, and to the stringers F are also secured compressiombraces f, against which the counter-buffers (Z rest when pulled to the right. These compression-braces are stiffened by braces g, as shown- To the upper end of the counter-buffers are secured short levers h, to each of which a cord or rope, j, is secured. one end is secured to the traveler farthest from the engine, and then is led by means of grooved pulleys to a drum, Z, driven from the engine I).

The operation is as follows: The train of traveling drums being brought over the place from which it is desired to move the earth or similar material, (the counter-buffers d nearest to the train having been previously lowered,) the train is drawn back until the sleeves on the shaftV arein contact withthe counter-buffers d, and the winding-rope Z is then drawn, so that the pawls Q can be thrown out of contact with the ratchet-wheels P and the buckets freely descend by their own weight. The pawls are then again thrown into contact with the ratchet-wheels. WVhen the buckets have been filled, the engine I) is started and winds the rope Z onto the drum a and off of the drum Y, thereby causing the is a tail-rope, which at latter to revolve, which, through shaft V and bevel-gears U T, imparts a rotary motion to the shaft L, and with it the drums N, thereby winding the ropes R upon them and raising the buckets S to the desired height when the motion of the winding-drum a is stopped and is left free to unwind. The tubs are prevented from descending by the pawls Q. The train is then drawn back by the tail-rope It to the point where it is desired to dump the load. When the buckets are emptied, the train is drawn back by means of the windingrope Z, and the operation is repeated.

Although in the drawings I have shown three buckets, it is obvious that more may be employed or only one, as may be required, and more than one track and train of buckets and travelers may be employed side by side upon the same framing.

I have described the buckets and travelers as carrying their load from the engine; but, if desired, they can be carried toward the engine by reversing the action above described and properly manipulating the counter-buf- 2 5 fers. The counter-buffers not in use are held up out of the way, as shown at d.

Although in the foregoing description the shafts L L are described as being connected by universal joints so as to pass round curves, it is obvious that when the apparatus is to be used on a nearly straight track other joints or a straight shaft without joints may be employed.

What I claim as my invention is 3 5 1. In an apparatus for raising earth or other material, a train of drums, N, attached to a continuous shaft adapted to travel and hung from rail H, in combination with the ratchetwheels P and pawls Q, substantially as and for the purpose set forth.

2. In an apparatus for raising and moving earth or other material, a train of drums adapted to travel, secured to short shafts mounted in bearings hung from the track, in

combination with short shafts connected to the shafts of the drums by universal joints, substantially as and for the purposes set forth.

3. In an apparatus for raising and moving earth or other material, a train of drums, N, adapted to travel, secured to shafts L, mounted in bearings K, hung from the track H, in combination with shafts L, connected to the shafts L by universal joints M, bevelgears T U, shaft V, driving-drum Y, and rope Z, substantially as shown and described. 5 5

4. The ring-buffers m, in combination with the shaft V, carrying the driving-drum Y and bevel-gear U, and the counter-buffers cl, substant-ially as and for the purposes set forth.

5. A train of drums mounted upon a shaft and supported in bearings hung from the track, in combination with bevel-gears T U, driving-drum Y, and rope Z, substantially as and for the purposes set forth.

6. In combination with a movable frame supporting a track, a train of drums secured to a shaft mounted in bearings hung from the track, said shafts consisting of sections secured together by universal joints and driven by bevel-gears from a counter-shaft, which is driven by a rope passing around a drum on said shaft, substantially as shown and described.

7. In combination with a movable frame supporting a track, a train of drums secured to a shaft mounted in bearings hung from the track, and driven by bevel-gear from a countershaft, which is driven bya rope passing around a drum on said shaft, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HOWARD ADAMS CARSON.
