DUMP-CAR.

SPECIFICATION forming part of Letters Patent No. 723,516,dated March 24, 1903.

Application fileddanuary 5, I903. Serial No. 137,941. (No model.)

To all whom it may concern:

Beit known that I, FREDERIO A. DELANO, a citizen of the UnitedStates, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Oars, of which. the following is a specification. The invention relates to that class of cars which is used for the purpose of carrying loose bulky freight and which may be used,

as desired, for the purpose of carrying such freight as ballast, coal, ore, and the like and permitting the larger portion of it to be automatically discharged, as will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and efficient dump-car with a flat floor portion and inclined discharging portions,by which dilferent kinds of freight may be carried and discharged to suit difierent circumstances and conditions.

Further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists principally in a dump-car in which there are combined a supporting-frame, a fiat bottom portion extending longitudinally of the car out andto each side of the longitudinal center and provided with downwardly and outwardly inclined lateral edges forming discharging-aprons, side boards formed of vertical portions arranged at or near the outer side of the car, and swinging doors pivotally secured to the vertical portions, inclined downwardly and inwardly to meet the floor portion:

The invention consists, further and finally,

in the features, combinations, and'details of construction hereinafter described and" view showing but one of the lower swinging side boards swung into discharging position.

In the art to which this invention relates it is well known that it is very desirable to have dumping-carstbat is, cars adapted to carry loose bulky freight and automatically discharge t-he same. It is also well known that these dumping-cars do not at present meet all conditions required by the railroads. For instance, oftentimes it is not desirable to have a dumping-car which can only carry bulky freight and discharge it through or outside of its bottom portion, for the reason that all of such freight must be discharged at one and the same operation, while it is often desirable to discharge a portion only of the freight automatically to either orboth sides of the car, leaving the rest to be discharged by shovel or manual labor to some other portion of the railroad. -Again, it is well known that it'is desirable to have a car which may 'be used for dumping purposes when desired, but which can also be used for carrying freight requiring a flat bottom portion-such as railway-rails, telegraph-poles, lumber, and material requiringmanual'handling.

The principal object, therefore, of this invention is to provide a car which will remove used to carry manyvarieties of freight which require a1fiat bottom and also for the carrying of'loose bulky freight and automatic-discharge of the same, all of which will more fully hereinafter appear.

In illustrating and describing these improvements I have only illustrated and described that which I consider to be new, taken in connection with so much thatis old as will properly disclose the invention and enable those skilled in the art to practice the same, leaving out of consideration other and wellknown elements, which if set forth herein would only tend to confusion, proliXit-y, and ambiguity.

gIn constructing a car in accordance with these improvements I provide a supportingframework formed of a plurality of deckbeams a, extending transversely of the car and the entire width thereof. These deckbeams are preferably formed of metal I-beams of the desired size in cross-section to resist the stress and strains incident to the ordinary usage of the car. Secured to these deckbeams is a plurality of longitudinal sills 19, forming intermediate sills, and a pair of longitudinal sills c, forming center sills, which extend longitudinally the entire length of the car and are secured to the upper surfaces of the deck-beams.

To carry the desired load, the car is provided with a floor portion formed of a central flat portion 01, arranged longitudinally of the car, having downwardly and outwardly inclined lateral edges forming dischargingaprons e. These discharging-aprons, as well as the central fiat floor portion, are preferably formed of sheet metal and extend downwardly and outwardly from the longitudinal sills to the extreme outer edges of the deckbeams, to which they are also secured. In order to confine the load, as well as furnish means for strengthening the frame structure to withstand the stress and strains incident to ordinary use, side boards are provided, formed of upper fixed vertical portions g and lower swinging portions h, pivotally secured thereto, which extend when in operative position downwardly and inwardly until they meet the flat floor portion at its intersection with the inner ends of the discharging-aprons.

It will be seen from an examination of the drawings and the foregoing description that the discharging-aprons and the upper fixed portions of the side boards act as bottom and top chords, respectively, of a girder, which are connected and secured together at intervals by a plurality of vertical posts 2'. These posts are attached to the deck-beams and the inner surface of the fixed side boards and act as struts of the chords. Each end of the car is provided with a vertical end board f, as shown, which may also be formed of a piece of sheet metal. From the foregoing description, construction, and arrangement and an examination of the drawings it will be seen that these side girders dispense with the usual side sill and the expense attached to constructions which require the same, all of which will be understood and appreciated by those skilled in the art.

To close the doors and hold them in locked position, many devices may be used; but I only show one means of accomplishing the same-viz., a rock-shaftj, rockingly mounted in suitable hearings in the framework of the car and provided with a plurality of locking lugs or projections 70, which when the parts are in the position shown in Fig. 2 serve to hold the swinging side boards in locked po sition, but when rotated or rocked to the positions shown in Fig. 5 permit one or both of the swinging side boards to be swung to their rest easily thereon and does not require to be automatically discharged; second,that it may be used, as shown in Fig. 4, for the automatic discharge of abonteighty per cent. of the load to both sides of the car, leaving the rest or central portion to be discharged by manual labor, and, third, that it may be used to discharge nearly one-half of the load to one side of the car only, leaving the balance to be discharged by manual labor to such other point or points as it is desirable to discharge the same, all of which will be understood and appreciated by those skilled in the art.

I claim- 1. In a car of the class described, the combination of a supporting-frame, a fiat bottom portion extending longitudinally of the car out and to each side of the longitudinal center and provided with downwardly and outwardly inclined lateral edges forming discharging-aprons, and side boards formed of vertical portions arranged at or near the outer side of the car and swinging doors pivotally secured to the vertical portions inclined downwardly and inwardly to meet the floor portion, substantially as described.

2. In a carof the class described, the combination of a supporting-frame, a bottom portion provided with a flat central portion extending longitudinally of the car and provided with downwardly and outwardly inclined lateral edges forming dischargingaprons, and side boards formed of fixed vertical upper portions at or near the outer sides of the car and lower swinging portions pivotally secured thereto and inclined downwardly and inwardly to meet the edges of the floor portion, substantially as described.

3. In a car of the class described, the combination of a supporting-framework formed of a plurality of deck-beams arranged transversely of the car and a plurality of longitudinal sills resting upon such deck-beams, a floor portion formed of a flat central portion arranged upon the longitudinal sills and provided with downwardly and outwardly inclined lateral edges extending to the outer edges of the deck-beams, and side boards formed of upper fixed vertical portions at the outer sides of the car and lower swinging portions pivotally secured thereto and extending downwardly and inwardly to meet the edges of the .fiat floor portions, substantially as described.

4. In a car of the class described, the combination of a supporting-framework formed of a plurality of deck-beams arranged transversely of the car and a plurality of longitudinal sills resting on such deck-beams, a floor portion formed of a fiat central portion arranged upon the longitudinal sills and provided with a discharging-apron at each lateral edge of the same formed of a piece of sheet metal, side boards formed of upper fixed vertical portions and lower swinging portions, and a plurality of side posts secured to the deck-beams to the upper fixed portions of the side boards so that such side boards, discharging-aprons and side posts form the bottom and top chords and struts, respectively, of a side girder, substantially as described.

5. In acar of the class described, the combination of a supporting-framework formed of a plurality of transverse deck-beams extending the entire width of the car and a'plurality of longitudinal sills laid thereon and secured thereto, a floor portion formed of a car, and a plurality of vertical side posts secured to the deck-beams and extendingupwardly therefrom and inside of the fixed vertical side boards to which they are secured, substantially as described.

6. In a car of the class described, the combination of a supporting-framework, a fiat floor portion thereon extending longitudinally of the car and to each side of its longitudinal center, side boards extending upwardly from the framework of the car and formed of fixed vertical upper portions at or near the outer sides of the ear and beyond the lateral edges of the flat floor portion and lower swinging portions pivotally secured thereto and inclined downwardly and inwardly to meet the flat floor portion at or near its lateral edges, and side posts extending upwardly from the frame portion, and inside of the vertical fixed side boards to which they are secured, substantially as described.
