Specification of Letters Patent.

Serial No. 120,959.

To all whom fit1/my concern Be it known that l, Fammi S. lneonosnv, a citizen of the United States, residingat St. Louis, in the State ot Missouri, have 1nvented a. certain new and uset'ul l'mprovement. in Dump-Cars, of which the 'following iS a full, clear, and exact description, reference being had to the accompanying draw- Ines.

tIhe object of this invention is to produce a very light and strong railway ear; the principles ot' the invention are particularly adaptable to dump cars of the type known as the lngoldsby dump ear though the invention is not limited thereto. Such type of car is illustrated ir. Patents Nos. 551,319, (313,279, and (332,650, granted to Ine Dec. l0, 1895, Nov. l, lStlS, and Sept. 5, 160), respectively; it has sides, preferably trussed or gil-der, and a central longitudinal beam to which there are hinged dumping doors swinging downward at their outer edge.

AS the car has been heretofore ctmstructed, the central beam has carried halt oi? the load and each ot the sides a quarter ot' the load, each bolster thus receiving at its center one fourth of the load and at each end one eighth. Heretotore I have braced the longitudinal central beam by trussing beneath it to enable it to carry halt the load, but as the ear sides must necessarily he oi considerable height to form said walls tor the load, I have determined to avail myself of their strength to carry a portion of the load heretofore carried by the central heam. l do this by dividing the central beam in two and resting its ends at the middle o'l the car on a cross beam carried by the sides, so that the two sides, (in addition to their halt o't' the load) together carry one halt ot' the load on the central beam, that is, for each side one eighth oit the entire load in addition .to the one fourth heretofore carried, making each side carry three eighths of the load, wherefore each holster carries at its center one eighth ot the load and at each end three sixteenths. The value of this arrangement is evident when it is remembered that the strength of a beam increases as the square et' its depth, and that the car sides may be made and simply for purposes of retaining the load should be made) much deeper than it is possible to make a central truss without carrying the central beam up unduly high into the car, wast-ing space, or unduly raising the center of gravity of the whole car.

The present invention consists of such an apportionment of the strains, and the 1n -ians by which I am able /to accomplish it, resulting in doing away with any truss for the central beam, and lightening and simplify-- ing the construction. Thisis clearly illustrated herein in the drawings and is hereinafter t'ully explained.

in the drawings, Figure l is a side elevation ot a little over one half a car embodying the present invention; Fig. 2 is a longitudinal section of suoli car from the other end, the section heilig taken at one side of the center as indicated bythe line Q-Q of Fig. 3; Fig. 3 is an end view of the car, half oi' it being in vertical section. Fig. 4 is a bottom plan of a portion ot' a car 'at the middle thereof, and Fig. 5 is a top plan of such portion. Fig. 6 is a transverse section of the car at the center. Fig. 7 is a 'cross section ot' the central beam, being on the line 7---7 ot' Figs. 5 and G. Figs. S and 9 are diagrams illustrating the distribution of the weight ot' the load in the present 'form of car and in my earlier form, respectively.

The sides A. o the car are plate girders composed each of sheet steel plates a, 'an upper chord o', lower chord; (1.211,3, and struts a, u, riveted to the pl-Bies. At the ends ot' the car there are inclined tloors B riveted to the girder plate of the sides. At the upper end ot this inclined Hoor is an upper cross beam C and beneath this beam is the bolster D. The struts a* are secured to the ends ol' the bolster. Secured to the side girder and to the bolster are the projecting longitudinal beams C secured to the end sill C2 and braced by diagonal posts C. Running trom the end ot the car are suitable dral't plates It) which are secured to the lholster, and i'rom the junction ot' .these draft plates with the end sill are diagonal beams C running tlnt'iugh the bolster to the girder sides. 'lhe specific form of this much of the construction does not. enter into the present invention.

At the middle of the car on the inner side of' cach girder plate a, I prefer to rivet tri- Iet angular strengthening plates G, and extending crosswise of the car I place the beam H which for dump cars preferably is an inverted V-shaped plate havin its ends /L flanged outwardly and rivete to the sides through lthe intermediate strengthening plates. This cross beam is given depth by the angle beams J riveted toit and bowing down .toward the center of the car. y

The central longitudinal beam is designated N. As heretofore stated, in the Ipresent invention this is divided into two parts each being supported at one end by a bolster D and at the other end by the central cross beam H, where they are connected by the underrunning splice plate n. The beam N consists of an inverted V-shaped sheet metal plate (of aslmany sheets. as desired) strengthened by suitable cross braces P, P, P2. At the bolster end, these longitudinal beams extend across the center frame d of the bolster between that frame and the tens sion vstrap d thereof, hese three vparts being riveted together. he bolster may have a lower channel member d2 and intermediate struts d3 and bi'aces dt, as shown. The

` self and Joseph R. Bowling, and will not be herein further described.

At thecenter of the car, as stated, the two sectionsof the longitudinal beam N are secured to the cross beam H. This is accomplished by connections n beneath the .longitudinal beams, riveted to them and to the cross beam. In order to take the buiiing of plates Q which continue the planes o the' :.jv; longitudinal beams within the cross beam Bti . 'the angles n.

and tugging lstrains directly through the longitudinal center of the car, as well as fto brace the cross beam H, l provide a air l-l, these plates being Banged inwardly at `their ends g and being riveted in place, 'the same rivets passing through these langes q through the cross beam Hand through This construction` makes a ,very rigid' structure for the longitudinal strains, while the weight on the longitudinal beams at the .center is transferred to the sides of the car.

- Now, in the above described construction, that portion of the load which would pril imarilyY come on the .central beam (that is, halt the entire load), has halffone 'fourth the entire load) taken by the cross beam H, the other quarter of the entire load being beams, as indicated. ycar illustrated by Fig. 9, half of the load distributed to the two centers of the bolsters, one eightheach. The quarter of the entire load carried by the central beam is distributed to the two sides, so that each side carries its own quarter of the load, and the eighth of the load received from. the central cross beam, making three eighths andfthus distributing to each end of each of the bolsters three sixteenths of the entire load. The central longitudinal beam being thus relieved of half its work may be made sutliciently rigid without any trussing whatsoever, being simply braced bythe cross braces which are otherwise necessary to form the supports for the floor hinges. The result is that a simpler car is produced, and oneof fewer parts and much lighter, the load being distributed to the parts which are necessarily of such size as to carry it.

The distribution of the weight is clearly illustrated in the two diagrams, which may be considered as beams resting on top oi each other and corresponding to the bolsters, sides and longitudinal and transverse ln the older form of is borne by the central beam, and carried directly to the center of the bolsters, each; and a quarter ot the load isborne by each car side, 2; coming` onto each end of each bols-ter.

In the new form, illustrated in Fig. 8,

These doors, which are adapted to swing down ward between sector-shaped shields V, may be secured in closed position by locking mechanism, and after beingrdropped they may be elevated by suitable raising mech anism. The locking` and raising mechanisms (designated generically 'l` and U, respectively)` are fully shown in the prior patents referred to and willA not be herein further described. The braces l? carry the toggles of the raising mechanism, andthe braces P bumpers for the doors. Each of these braces consist of )airs of u rights and.
