T0 all whom, it mfay concer-71,.-

Beit known that I, GEORGE H. HULETT, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Excavating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionv relates to certain new and useful improvements in apparatus for excavating, removing, and depositing earth on a large scale-such, for instance, as the construction of canals-the object of the invention being to provide a system of cooperating apparatus all mounted on tracks extending lengthwise the cut or excavation and on roadways or berms at the side of the cut and adapted to make the excavation, to remove the excavated material and deposit same at the sides of the cut or excavation in an even and uniform manner, the entire operation being continuous and uninterrupted.

With this end in view my invention consists in the combination and arrangement of the s everal parts of the system, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is aview in end elevation of an excavation, showing th'e apparatus therein. Fig. 2 is a similar View showing the double-cantaliver endlessbelt conveyer mounted on a roadway on top of the Spoil-band formed by the apparatus of Fig. 1. Fig. 3 is a plan View showing the apparatus of Figs. l and 2 in their respective positions in the ditch and on the spoil-bank. Fig. 4 is a view in end elevation of the excavating-machine and feeder, and Fig. 5 is a view tents. This hopper 4 is of somewhat greater capacity than the shovel and, if desired, may serve two excavators working on opposite sides of same. This hopper 4 is mounted on a truck 5, traveling on a track 6, parallel with the excavator-track 2, so that it may be moved along with the excavator, and is provided with inclined sides 7 and an open bottom, under the restricted opening of which the reciprocating plunger or feeder 8 rests and moves. This plunger or feeder is mounted in suitable guiding-supports 9 and is reciprocated by the engine 10, with which it is connected bysuitable gearing, the engine being mounted on the car 5, carrying the hopper.

At each stroke of the plunger 8 the bottom of the hopper is opened, and the spoil which passes therethrough is engaged by the plunger on its return stroke and pushed onto the endless-apron conveyer 11, which latter is also carried by the car 5. This apron conveyer 11 is located in rear of the hopper 4 with its front end in a position to receive the spoil ejected from the hopper and is carried by the frame 12, supported near its free rear end by the supports 13. This conveyer projects upwardly and rearwardly, as shown, and terminates over a hopper 14, carried by the frame 15, which carries the transverse belt conveyer 16, so that as the spoil is discharged from the conveyer 11 it falls into hopper 14 and passes from thence onto the transverse conveyer, by which it is carried over the side of the excavation and deposited.

By interposing the feeding device- 8 between the hopper 4 and the apron elevator or conveyer 11 the spoil, from fine dirt up to large pieces of rock, will be delivered uniformly to the apron 11, thus preventing the possibility of overloading the apron 11 or the belt conveyer 16, onto which the apron discharges. This apron 11 is actuated by the engine 10 and gearing carried on the platform of the car 5; hence is in motion so long as the feeding device is in motion.

The transverse endless conveying-belt 16, which receives the spoil from the apron 11, is located in rear of 'the excavator 1 and apron 11 and at right angles thereto. This belt 16 is inclined upwardly to one side of the excavation or ditch and extends suiiiciently lIO far beyond the side thereof to deposit the spoil at a point where it will not have to be rehandled during the operation of shaping the sides of the ditch. This belt 16 is supported throughout its length by the doublecantaliver tower 17, which is mounted on a truck 18, which travels on a trackway 19, located at the side of the excavation, and discharges the spoil which forms the first spoilbank. This belt conveyer 16 projects about equal distances at both sides of its supporting-truck 18, with its outer end at a height sufficient to form the first spoil-bank without changing its inclination.

In Fig. 3 I have illustrated an excavation representing the half of a canal and on the No. 3, and LCut No. 4 and have also illusv trated a second level, showing the steamshovel and apron therein. bank would probably be formed from the excavators in cuts Nos. 1 and 2, while the spoil from cuts Nos. 3 and 4 is carried over spoilbank No. 1 to fo'r-m a second spoil-bank No. 2. In forming this second spoil-bank two belt conveyers are employed, one of which (marked 16a) is pivotally supported at its ends on trucks 20, one of which is mounted on a track 21, located in the ditch adjacent to and parallel with the trackway on which the hopper and apron elevator are carried, while the other truck is mounted on trackway 19, on which the cantaliver-tower 17, serving the excavator in cut No. 1, is mounted. This conveyer 16a discharges into the hopper 22 of the belt conveyer 16, carried by the cantal liver-tower 17, mounted on a truck which travels on the track 23 on the road-bed at the top of spoil-bank No. 1.

With my apparatus I prefer to` mount the outer or discharging conveyer 16 on the cantaliver-tower and the inner conveyers 16*l on pivoted trucks.

With the apparatus arranged as described all the parts thereof can be advanced as the work progresses and the excavated material removed from the ditch and deposited at the sides without any rehandling, the operation being continuous so long as the steam-shovels are at work. Again, by employing hoppers and a feeder for each excavator there is no danger whatever of overloading the aprons or belt conveyer, as would be the case were the contents of the steam-shovels deposited into open-bottom hoppers or directly onto the aprons. By interposing the feeders the material is uniformly distributed onto the apron and from the aprons to the belt conveyers. Hence overloading either of these parts is absolutely prevented. Again, by mounting the trucks on tracks parallel to each other and to the cut all the parts of the The first spoil-v apparatus may be advanced as the work progresses without any interference from one another and without interfering with one.

another while at work.

While I have shown a single transverse conveyer and also a transverse conveyer made up of two endless conveyers, it is evident that each transverse conveyer may be made up of more than two sections, so that the spoil may be removed any reasonable distance from the cut, and by arranging them as shown in Fig. S-that is to say, by providing the hopper and feeder in cut No. 1 with'a single transverse conveyer--the spoil discharged therefrom forms the roadway on which to mount the supports of the next conveyer in order, and so on throughout the system.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to limit myself to the exact construction of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a track laid longitudinally in the cut, a steam-shovel or other excavator mounted thereon, a second track parallel with the first track, a truck carrying a hopper and feeder on said second track, an

elevating-conveyer also carried by the truck carrying the hopper and feeder, and an endless-belt conveyer receiving the spoil from the elevating-conveyer and located at right angles to the excavation and mounted to move in the direction of length of the latter.

2. The combination of a track laid longitudinally in a cut, a steam-shovel or other excavator mounted thereon, a second vtrack parallel with the first track, a truck carrying a hopper and feeder mounted on said second track, an endless conveyer also mounted on the truck carrying the hopper and feeder, a track on the berm or bank adjacent to the cut, and an endless conveyer carried thereby, and located in a position to receive the spoil as the latter is discharged from the endless conveyer leading from the hopper.

3. The combination with a track laid longitudinally in a cut, a steam-shovel or other excavator thereon, a second track parallel with the first track, a car carrying a hopper and a IOO IIO

elevating-conveyer also extending in the direction of the length of the tracks for receiving the material as it is fed from the hopper, of a plurality of endless-belt conveyers located transversely to the cut and mounted on tracks parallel to the track carrying the hopper and feeder, the iirst conveyer delivering the spoil to the next succeeding one, each system of conveyers depositing the spoil to ,form the roadway on which to mount the outer support of the next following couveyer. I

5. The combination with a car-mounted exf cavator, a car-mounted hopper, a feeder for the latter and an elevating-conveyer located in a position to receive the spoil from the feeder, of a car-mounted cantaliver-tower mounted on a truck running parallel with the excavator and carrying a transverse belt conveyer onto which the spoil is deposited from the elevating-conveyer.

ln testimony whereof I have signed this specification in the presence of two subscribing witnesses.
