DUMP-CAR.

SPECIFICATION forming part of Letters Patent No. 704,578, dated July 15, 1902.

Application tiled March 11, 1901.

To @ZZ zultom it may concern:

Be it known that We, EDGAR M. RAY and ROBERT B. MCCONNEY, citizens of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and usefulY Improvements in Dump-Cars, of which the following is a specification. Y

This invention relates to that class of cars ro which are adapted to carry coal, mineral-bearing ores, gravel, sand, and like substances, to the means by which the holding portion thereof is dumped, and, iinally, to the means by which the holding and dumping mechanr5 isms are held in position during transportation, all of which Will more fully hereinafter appear. p

The principal object of the invention is to provide a simple, economical, and efficient 2o dump-car.

A further object is to provide a dump-car having a iixed frame with means for holding the load in position for transportation and permitting it to be dumped at desired times.

A further object is to provide a dumpingcar having a iixed frame portion with a holding dumping-box and means for holdingit in looked position, as Will be hereinafter more fully described.

The invention consists, principally, in a dump-car in which there are combined a fixed frame portion, a body portion vibratingly held therein, and means for holding the dumping body portion in carrying position.

The invention consists, further, in a dumping-car in which there are combined a fixed frame portion, a dumpingY body portion eX- tending longitudinally of the car and swingingly mounted in the frame portion, `and 4o means for looking and holding the dumpingbody in carrying position.

The invention consists, further, in a dumping-car in which there are combined a fixed frame portion and tilting dumping-boxes ar- 45 ranged longitudinally of thercar and open at the outer side, swinging sides hinged to the frame and forming closures for the open side of the holding-boxes, and means for holding the dumping-box portions in carrying posi- 5o tion.

' The invention consists, further and iinally,

sean no. 50.668. (No model in the features, combinations, and details of construction hereinafter described and claimed.

In the art to which -this invention relates it 7o is Well known -that the problem ofcarrying broken material-such as coal or mineral-bearing ores, gravel, and sand-and delivering it to a desired point of destination as economically as possible is one that has long interested railroads and users ot railroad-cars.

In the particular class of cars to which this invention rrelates it is well known that the majority of such cars may be used for the purpose ofcarrying materials and dumping 8o them, but that, generally speaking, they are unlitted for the purpose ofl delivering articles, excepting by an automatic dumping process. It is often desirable, however, to have these cars so arranged that the material 8 5 can be shoveled out of the cars. This is especially the oase in delivering coal or mineral-bearing ores in small quantities when it must be discharged by shoveling.

The principal-object, therefore, of our in- 9o vention is to provide a car of the class described Whioh is simple and economical to build and efficient in operation, one that can be used either for the purpose of automatically dumping the load or shoveling it out by manual labor, all of which will be appreciated by those skilled in the art.

In illustrating and describing these improvements We have chosen to illustrate and describe them in connection with a peculiar roo type of frame, and have only deemed it necessary to describe so much of a car as is old,

taken in connection with what we consider to be new, as will properly disclose the invention to others and enable those skilled in the art to practice the same,fleaving out of consideration other and Well-known parts, which, if illustrated and described herein, would only tend to confusion, prolixity, and ambiguity.

In constructing a carin accordance with these improvements we make the underframe of center sills a extending longitudinally of the car and intermediate sills b extending likewise at a point between the sides of the car andv the center sills. These sills extend outwardly at each end of the car, as shown in Figs. l and 2, and are tied together at the extreme ends by means of the end sills c and end plates d. To further strengthen the lindert-raming and furnish side stakes or posts for the car,we provide aplurality of U-shaped T-beams e, which are arranged transversely of the car-frame underneath the sill portions above described and extend upwardly at each side of the car with the iianged portion of the beam arranged on the inner side, so that the supporting-sill may rest thereon and the sides of the car be fastened thereto. These U- shapde metallic members act in a dual capacity-that of tie rods and side stakes or posts. They are secured together longitudinally at their upper ends by means of channel-beams f, which tie them together in an efficient manner. The web of such channel-beams is secured to the flanges of the T-beam side posts so that they present a smooth inner surface to the interior of the car with their fianges extending outwardly. These channel-beams, which secure the U-shaped T- beams together, may be made in sectionsthat is, they may be made formed of two angle-irons joined together by a Web-plate or may be made of one integral channel-beam to suit different circumstances or conditions. The'ends of the car are formed of a steel plate w the entire width and depth of the body portion. To strengthen the same, end posts g, formed of angle-irons, are provided at each end of the car, secured together by means of the horizontal member of the end U-shapecl T-beams and at their upper ends by means of angle-irons 7i., which also secure them to the upper endsof th'e U -sliaped beams, as shown particularly in Figs. l and 3. One side of these end posts may be also secured to the outer Aintermediate sills, as shown particularlyin Fig. 3. The portion of the car above described forms what we prefer to term a fixed frame portion-that is,

such parts are rigidly secured together and the relation at all times fixed so as to practically support the movable parts and load, as hereinafter more fully described. l

To provide means vby which the load may be carried during transportation and dumped or discharged when the desired destination is reached, we provide what we term dumping-box portions t', which are substantially 'box of it.

L-shaped in cross-section and practically U- shaped in longitudinal section-that is, the box portion is open at one side and the top, or, in other words, has one side portion, a bottom portion, and two end portions, but is lacking in a top portion and one side portion. These dumping-boxes are arranged longitudinally of the car and mounted upon rockshafts j and are formed of a plurality of L- shaped metal T-beams lc, extending transversely of the box and joined together by flat plates which form the inner side, two ends, and the bottom portion. These dumpingboxes are mounted upon rock-shafts above described, which in turn have their journal portionsin saddles or brackets t resting upon the sills of the car. A plurality or series of these supporting saddles or brackets is provided and the square rock-shafts Aare provided with cylindrical journals at the points in which they rotatablyengage with the brackets. We prefer to provide two or more of these dumping-boxes on each side of the car arranged longitudinally therewith, so that such car may be used to carry two or more different kinds of material, and, as in the case of mineral-bearing ores, carry dierent grades of ore. It will be understood, however, that the car may be provided with but one of these dump portions on each side of the car and extending longitudinally thereof.

It is desirable that some means be provided when the car is in carrying position to close the outer open side of the dumping-box and also to lock such dumping-box in fixed position to carry the load. In order to accomplish this result, a swinging door n is provided and pivotally mounted at each side of the car, preferably to the upper fixed portion of the side, so that when it is in its closed position and the dumping-box in` its carrying position, as shown in one-half of Fig. 2, the swinging door completes the closure for the open side and practically makes a complete To lock this swinging door in position, as well as to form a seal between the swinging door and the box, and thus prevent leakage of tine material, a hooked lockingplate m is provided, mounted upon a rockshaft o, adjacent to the outer lateral free edge of the dumping-box, as shown in Fig. 2. The swinging door is provided with a lip p, adapted to be engaged by the hooked edge 'on this locking-plate, as shown in Fig. 4.

The rock-shaft of this hooked plate is provided with an operating-handle q and one of the end stakes of the car with a link c, adapted to be slipped down over the free ends of the operating-handle and hold it in its locked position, which also assists in holding the dumping-box in its locked position.

To provide means by which the man ual exertions of the trainman may be used to tilt the dumping-box from a carrying to a dumping position, or vice versa, asegmental geared lever r is provided engaging with a handwheel s by means of a train of compound IIO gears t, all of which enables the trainman to tilt such boxes with the least exertion possible. A pawl n, may be used to engage with one of the spur-gears to assist in holding the dumping-box in locked position.

IVhile we have described ourimprovements with considerable detail as to form, construction, and arrangement, we do not desire to be limited thereto unduly or any more-than is pointed out in the claims. On the contrary, we contemplate all proper changes in form, construction, and arrangement, the omission of immaterial elements, and the substitution of equivalents, as necessity may demand or circumstances render expedient.
