APPARATUS FOR HOISTING AND CONVEYING EARTH FROM SEWER-TRENCHES.

SPEGIFJ IGATION forming part of Letters Patent No. 280,645, dated July 3, 1883.

Application filed May 15. 1883. (No model.)

To all whom, it may concern:

Be it known that I, PATRICK H. lVIOCAULEY, of Des Moines, in the county of Polk and State of Iowa, have invented an Apparatus for Hoisting and Conveying Earth from Sewer- Trenches, of which the following is a specification.

My object is to save time,'labor, and expense in making excavations for sewers and removing ground away on wagons; and my invention consists in the manner of forming and combining a portable elevated railwaytrack and car-dumping device adapted to be placed across a trench and under a portable derrick, as hereinafter fully set forth, in such a manner that a person on the elevated track can readily direct a bucket that is raised and lowered in'the trench by horse-power to con vey dirt from the bottom of the trench into a car 011 the track, and also move the car and dump its contents into a ivagon aside of the trench. a

Figure l of my accompanying drawings is a perspective view of myapparatus in position as required for practical use. Fig. 2 is a see tional view, showing a truck on the elevated track in position to receive the contents from a bucket suspended over it by means of the derrick and tackling. Fig. 3 is an enlarged detail view and longitudinal section of the elevated track and dump combined therewith. Fig. 4 is a top view of Fig. 3. Fig. 5 is a transverse section of the track and dump. Jointly considered, these figuresclearly illustrate the construction, application, and opera tion of my complete invention.

a a are the parallel rails of my elevated portable track. They are preferably made of hard wood covered with iron plates 1), connected by means of cross-pieces c, and supported upon frames d, that are rigidly fixed to their ends by means of bolts, or in any suitable way, in such a manner as to adapt the complete elevated track to be placed across a trench, as clearly shown in Figs. 1 and 2.

a are planks fixed on the outside of and parallel with the rails a to form walks for the operator.

at are the side pieces of the dump-frame, rigidly fixed against the ontsides and ends of the rails a.

f is a section of track pivoted between the pieces a by means of a rod, 9. I) are metal plates fixed on top of the pivoted track-rails. They extend beyond and terminate in upward wheel-supports b.

h are bridles pivoted to the suspended track'- section f by means of a rod, i, that extends through the side pieces, f and connected with the inside faces and ends of the track rails a by means of bolts k, in such a manner that the tilting motion of the pivoted tracksection f will be restricted by the bridles, as indicated by dotted lines in Fig. 3.

m represents a four-Wheeled truck adapted to be operated upon'thc elevated track.

Numbers 1 2 3 are the legs of a tripod or derrick, pivoted together at their top ends in such a manner that they can be folded into parallel positions relative to each other when not in use, and readily spread apart at their lower ends, to be set astride of a trench and over my elevated track.

' n represents a bucket having a hinged bottom, suspended from the top of the derrick by means of pulleys and a rope in such a manner that it can be readily raised and lowered in the trench.

a, is a rope-directing pulley attached to the lower end of one of the legs of the derrick. By passing the rope over this pulley and hitching a horse to its free end the bucket can be easily raised, when filled with ground, by the movements of the horse along the side of the trench. \Vhen a loaded bucket is thus elevated above the track, the operator can move the truck on under it and unlateh its hinged bottom, and allow the contents to drop into the box of the truck, and then move the truck over the elevated track and upon the pivoted section and dump f to engage the wheelsupports I). By then lifting on the front end of the truck-box sufficiently to disturb its balance the pivoted section will be tilted and the rear and open end of the truck will descend sufficiently to allow the contents of the box to drop into a wagon placed underneath, as clearly shown in Fig. 1. The operator upon one of the plank walks'of the elevated track can then depress the front end of the truck and move it in position to be filled again, and by so doing the pivoted section and dump will be readjusted as required to receive the loaded truck again. Clay, sand, earth, and rock, or

any material excavated from the trench, can thus be readily hoisted and placed upon a wagon to be carried away or dumped 011 the surface at either side of a trench to be in a convenient position for filling it into the trench again, and much of the time, labor and cost of shoveling dirt in building sewers dispensed with.

The complete portable apparatus can be readily advanced from one point to another as the excavation of the trench progresses.

I claim as my invention- 1. The portable elevatedrailway-track and dump composed of the rails a I), cross-pieces 0, frame (I (7, hinged track-section f, having wheelsupports I) I)", the pivoted bridles 71,

and pins or bolts 1 substantially as shown and described, to operate in the manner set forth, for the purposes specified.

2. The hoisting and conveying apparatus, composed of the portable elevated railwaytrack a b a a, the pivoted tracksection and dump f, having Wheel-supports I), and hinged bridles II, the derrick consisting of three legs pivoted together at their top ends, a suspended bucket having a hinged bottom, and a truck, on, substantially as shown and described.
