SELF-DUIVIPING CAR.

Specification of Letters Patent.

Patented Nov. 2S, 1905.

Application filed Nvembel' 27. 1903.v Serial No. 182.875.

To @ZZ whom t may concern:

Be it known that we, PATRICK R. BANNON and J AMES L. BANNON, citizens of the United States, residing at Joliet, in the county of WV ill and State of Illinois, have invented certain new and useful Improvements in Self- Dumping Gars, of which the following is a specification.

This invention relates to means for constructing railroad road-beds of dirt, stone,&c. or for conveying and dumping such material to form a roadway for any purpose; and it consists generally of a series or train of selfdumping cars which are coupled together, provided with suitable trucks, and constructed with bottoms and sides formed of short sections fiexibly coupled together to form an endless conveyer, which is adapted to travel over suitable pulleys, wheels, guides, or other supports and to convey the filling material to the rear end of the train, where it is automatically dumped upon the road-bed under construction.

The especial objects attained by our invention are the conveying of the filling material commonly used in the construction of roadbeds from the source of supply to the point where it is required and the dumping of such material directly on the road-bed, whereby much of the grading now done by hand-shovels is saved.

A further object is to provide means whereby the entire train-load of filling material may be conveyed to the end of a track laid to the edge of a gully, ravine, marsh, Sac., and

' dumped at suchpoint, thus providing a fill or foundation upon which the track may be extended, and the operation repeated until the work is completed, thus avoiding the erection of trestles or the use of false work, the frequent laying and raising of temporary or construction track, and other expensive expedients. 1 4

An additional object is to provide carrying means that may be loaded or filled at the top in any well-known manner and, if desired, may be unloaded at the sides with shovels in the usual way instead of automatically at one end of the train as especially provided by our invention. v

A further object is tosecure a conveying and dumping ldevice that may be easily moved over a track from a point of supply of the filling material to the place where such material is to be utilized.

In this application for patent we have shown our invention as applied to cars adapted to travel over railway-rails; but it will be apparent that the same principles may be utilized in connection with trucks mounted on traction-wheels. It will also be'plain that the supporting-beams, which constitute thel frame on which the conveyer travels, will permit of varied treatment as to size, material, shape, and arrangement, all within the scope of the essential features of our invention. Te therefore do not wish to be understood as confining our invention to the exact construction and arrangement shown herein, but intend that this application shall be a preferred exempliication of the principles of our invention.

In the accompanying drawings we have.

shown our invention which- Figure l shows in side elevation three cars constructed according to our invention combined with an engine of an ordinary form for transmitting motion to the conveyer which constitutes the car-floor. Fig. 2 is a top plan view of the cars shown in Fig. l. a longitudinal section of one car and the end of the adjacent car constructed according to our invention and on a larger scale than Figs. l and 2. Fig. 4 is a cross-section on the lines 4 4 of Fig. 3. Fig. 5 is a detail showing the rod-and-pinion gearing which is utilized in our invention as a feature of the driving means. Fig. 6 is a detail in plan, on an enlarged scale, of a portion of the driving devicesvwhich are secured to the under side of the car-floors and which, with the rod-andpinion gearing and intermeshing sprocketwheels, cause the travel of the car-sections. Fig. 7 is a detail showingthe method of supporting the car-floor at the dumping end of the train.

Referring to the details of the drawings, 8 represents the cross-sills of the car-frame, which are suitably supported on axles and wheels and to which are bolted the uprights 8a and the longitudinal sills 8b. Connected to the uprights about midway their top and bottom are transverse iron beams 8c, and at the upper ends of the uprights are channel-beams 8d, which extend longitudinally with the frame and serve as guides for the sides of the car-floor. Supported on the cross-sill beams in a series of views, of

8 are I-beams 9, which extend longitudinally of the car and furnish a support for the L- Fig. 3 is y IOO' IIO

bars 9, in which are suitable bearings for the shafts, on which are mounted the series of grooved rollers 10. Secured. to the upper fianges of the cross-beams 80r are short lengths of I-beams 11, to the upper flanges of which are bolted L-bars 11, in which are bearings for the shafts of the grooved rollers 12.

To malle the frame rigid and strong and provide bearings for shafts to be described, there are bolted to the beams 11 wooden beams 13, which extend longitudinally of the car and have bolted to them the upper portions of uprights 8. Secured to the center of the cross-sills 8 are coupling-heads 14:, which may be of any desired pattern and have adapted thereto any suitable form of coupling whereby two cars may be 'exibly secured together. Supported on the under side of the midway beams 8 are pillow-blocl s 15, which provide bearings for the shafting 18", by which power is transmitted from one car to the other. The car-bodies are of the general gondola form; but the fioors are constructed from plank in short sections 16, near the ends of which are suitably secured the iron plates 17f, which form the sides of the car and correspond in width to the floor-sections- Bolted to the under side of each car-licor section are short rails 16, the downwardly-depending web of which fits the grooved periphery of the rollers 12, thus forming guides and supports for the Hoor-sections which are loaded. To the upper sides of the Hoor-sections are bolted rails 16, ycorresponding to the length of such section, the web of which fits the grooved face of the rollers 10, which thus support the sections of the floors that have been unloaded. To the under side of the can floor and alongI the center of same are bolted plates 17, each of which is formed with rounded teeth 17 along its sides, with a pair of lugs 17 at one end and a single lug 17C at the opposite end, and said lugs have openings therethrough for coupling-pins. The lugs 17 of one plate are coupled to the single lug 17c of the adjacent plate by the coupling-pin 17d as clearly shown in Fig. 6. ltwill be understood that each of these plates corresponds in length to the length of one of the fioor-sections, so that the coupling-point is at the edge of each section. The plates 17 constitute a series of links in an endless belt, through which power is applied to the under side of the floor of the car-sections from sprocket-wheels, which mesh with the teeth of the plates. The door-sections are also secured together by hinges 17, as shown in Fig. 41.

Extending' transversely of the cars, near the ends thereof, and mounted in suitable bearings in the frame are shafts 18, on which are mounted sprocket-wheels 19 and beveled pinions 20. Arranged between the oppositelyplaced beveled pinions 2O are smaller beveled pinions 18, which are fixed on the opposite cnds of the shafts 18]. It will be noted, as shown in Fig. that the pinion 18 on one end of the shaft 18 of one car meshes with only one of the adjacent beveled pinions 20, thus transmitting motion thereto and driving the transverse shaft 18, on which said pinion 2O is mounted, whereby the opposite pinion 2O on the same shaft 18 is driven and communicates its power to the beveled pinion 18fL on the shaft 18b on the next car in the train, thus transniitting power from one car to the other. The sprocket-wheels 19 are so spaced on the shaft 18 as to engage the teeth 17l1 of the plates 17, thus causing the floor-sections to traverse the length of each car and of the whole train. At the outer ends of the first and last cars of a train composed of cars constructed as above described are mounted drums 20, having six flat sides which correspond in length to the length of the floor-sections and furnish supports for such sections when they turn to dump their contents at the unloading end of the train and when they return from their inverted or dumped to their upright position at the front end of the train, as shown in Fig. 1. These drums are mounted on the shafts 18, that carry the sprocket-wheels 19, and are arranged on opposite sides of such wheels and also near the ends of the shafts, so as to furnish a support for the floor-sections at the center and near the ends of the latter. The engine 21, mounted on the separate car Q1, may be of any desired construction and is used to drive the shaft Q2, which inturn, through suitable intermeshing beveled gears, drives the shafts 25, carrying beveled pinions which intermesh with the beveled wheels 20 on the ends of a shaft 18, suitably mounted at the end of the train. It will be understood that the gears 2O and the shaft 18 and shaft Q3, with its pinions, will be arranged on both end cars of the train, so that an engine for driving the conveyer may be applied at either end, as may be most convenient. 1t will be also understood that a train made up of cars of the character described will be hauled over a railroad-track by any suitable locomotive, which will be coupled to the train at the end opposite the dumping-car.

1n operation a train of cars embodying the features above set forth may be filled at the top by any suitable loading apparatus, the cars being moved past the loading-point as fast as they are filled. When all the cars are full, the train will be pushed rear end first by a locomotive to the place on the road-bed to be filled, when the rear or dumping car will be run out as far as the road-bed will permit, whereupon the engine 21 will be started, thus moving the conveyer-sections of the loaded cars toward the rear end of the train, where as the sections turn about the drum on the outer end of the last car the material will be dumped directly on the right of way or roadbed under construction. When the bed has IOO IIO

been lled to the desired grade at one point, new rails will be added at the end of the track to permit the continuation or extension of the filling operations as before until the work is completed.

I/Ve have not shown in detail the construction and arrangement of the driving means for the car or conveyer sections, because it is manifest that various methods may be adopted for applying` power to such sections to cause them to traverse a train.

Having thus described our invention, what we claim, and desire to obtain by Letters Patent, 1s-
