SPECIFICATION forming part of Lettere retene- Ne. 677,352, dated .my 2, 1901.

. Application filed March 22, 1901. Serial No. 52,327.' (No model.)

To aj whom. may concern.- A Be it known that I, HARRY STILLSON HART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Ulinpois, have invented certain nen7 and useful"` Improvements in Convertible Dump-Cars, of

Which'the following is a specification.

My invention relates to that class of cars.

which is adapted to be used as a dump-caret. e., a hopper-car-and which is arranged to be converted into a gondola car-a car with a fiat bottom and vertical sides -and particularly to the means by which the movable sections that form the inclined hopper sides at one time and the floor-bottom at another time of which will more fully hereinafter appeal'. f

The principal object of 'the invention is to provide a simple, economical, and efficient convertible dump-car; and the invention consists in the eatu res, combinations, and details of construct-ion hereinafter described and claimed.

In the accompanying drawings, Figure lis a transverse sectional elevation of the body of a car constructed in accordance with .my improvements, showing the movable sections in one position to form a dumping gondola car and taken on line l of Fig. 3 looking in the direction of the arrow; Fig. 2, a similar view showing the parts in position to'form a hopper-car; r` Fig. 3, a longitudinal sectional elevation ot' one end of a car as it appears -When constructed in accordance with these improvements and Iarranged to form a hopper-car, taken Online?) of Fig. 4; Fig. 4, a plan view of one end of the car as it appears when constructed in accordance with th ese improvements and with the parts in position to form a hopper-car looking at it from above; Fig. 5,

asimilar view of the parts arranged to form a gondola car orcar with a fiat dumping-bottom; Fig. t', a cross-sectional elevation of a car constructed in accordance with these irnprovements and showing the movable sections in position to form a tlatbottom gondola car; Fig. 7, a detail view of the side frame portion, showing the slotted guiding l plate for holding the inclined end sections in' position; Fig. 8, an elevation of the end of one or" inclined end sections; Fig. 9,a 1ongitndinal sectional detail taken on line 9 of Fig. 3,showing a portion of the side, slotted guidingplate, and inclined end section with its snpporting-trunnion; Fig; 10, an enlarged sectional detail showing one 'of the vertical swinging sides of the carin an open position; Fig. 11, a similar view showing it in its closed position; and Fig. l2, a side elevation ot' a portion of the side of the car, showing the sectional swinging vertical sides.

In the art to which this invention relates it is well known that thereis ademend for a class of convertible c'ars which 'at certain seasons of the year can be used as ballastcars-viz., a car with inclined hopper sides arranged to carry and deposit ballasting mate-4 rial between .the tracs in piles, so that it will not interfere with the running. ofn the train-and that the car should be so constrncted as to be capable of being used'at other times as a fiat-bottomed orgondola car for carrying coal and other materials.' It is also desirable to have in this class of cars an arrangement by which the material in the gondola car can be discharged at each side thereof. In cases Where it is desirable to carry and discharge gravel or similar material bymeans of a dischargingplow to ferm embankments the vertical sides of the car should be arranged to open in such a inanner that as the plow is dragged from end to end of the car the material may be discharged at the sides. Again, gondola cars are also n'sed for carrying coal, bearing ores, metal, and similar materials, and it is dcsirable to have the bottom arranged in such a manner that the material can therethrough.

The principal object, therefore, of the invention is to provide a convertible dump-car which will contain all the advantages above set forth-z'. e., a car that can be used as a dnmping-hopper and gondola car or as a gondola car with swinging sides-all of which will more fully hereinafter appear.

In illustrating and describing Athese improvements it has been thought advisable to only show and describe so much as is old, in connection with what is new, as is necessary to' properly disclose the invention, leaving out otconsidcration other and well-known 'sitiotnso as to framing is provided with. side stakes 7c, ar:

the end sills b, and which is alsol providedl with intermediate sills c, running from endA to end of the car. The ear is also provided with transverse or needle beams d, which act to tie and support-the side and intermediate sillstogether.

o provide per portion which is formed of inclined sides made in two seetions-one a fixedy section e, forming the inclined sides of thev lower portion of the hopper, withjts vapexarranged longitudinal of and ator near the center of one side .of .which is provided with a the car, singleswinging'door f, pivotal-ly securedin position by means-ot lthe'hinges g, and the other an upper incliued'side h of the hopper, forming a movable side section thereof and which is provided with ixed ooring'j of the ear, turn secured in any usual mannerto the side and intermediate sills. As 4shown in Figs. 2, 3, ande, these parts are arranged to form a ballastear, and while' the inclined sides do not form a continuous incline it understood that they can be so arranged if it should seem desirable o r necessary. To support theuppe inclined sides in their open poform a ballastcar, the underranged inthe east-iron socketsl and carrying the permanent side sections m oi' the car, asV fully set forth. Where it; is desirable, (and I will say I think italways i hereinafter more pret`erable,) end portions fn are provided and arranged at an incline at 0r When desired to use or convert thecar into shown in Fig. 6, the upper swinging sections of the hopper are folded ina gondola car, as

wardly, beam s, arranged longitudinally of the ear and pivotally mounted in sockets i. The'inclined end portions are first raised, so that they may-be swung rearwardly toward the end of the car, and then lowered aS-.the trunnions slide downwardly in theA straight.v4 portion u of the grooved plate ungtil` they: lie in a fiat plane. as shown in 'Fig'., and cover for a Aballast-caigI make a li'op-I hinges t', hinged to the which flooring is in will be'l near` each end of the inclined sides, as shown particularly in: Fig. 3, and at the upper portion thereof only. These end portions are provided (see Fig. 9)

`upper ends of the sidestakes, a lower portion arranged y position roekshafts so asto rest upon a swinging center the opening 29 (Shown at the saine piace in Fig. 4.) The end of the ear is provided with permanent ends fu, as shown in Fig. 5, which are secured to the ends ot each of the sides and which act to practically' complete the gondola car.

Itis desirable thatmeans be provided by` which anymaterial in a gondola ear maybe dumped through the bottom thereof. To accomplish this resul lief's lwin'ging center beam s vis' provided, extending out from either. end 'thereof to the end ofthe ear and at one end cari-yin g a handF lever x. By swinging this hand-lever first in 'one direction the swinging center beam is `moved, so that one ofj'the swinging sections h may drop down into the position shown-in Fig. v1. B y 'swinging the hand-lever' new in the opposite direction the other swinging secftion It may also dropdown andall of the material in the car descends into the hopper, from which itmay be 4discharged through .the door f, as in the case of a ballast-car. It is highly desirable'that these swinging upper hopper side portions be made in several seeA ving al' bar or rod wtions, so that the partsover' the needle-beams,

as shown at h "inrFigs; .land 5,.e'an strike the needle-beams andv yet not'actto prevent the other sections of the doors from'swinging down agai'iist 'the lower'fixed portion of the hopper vto rest,or be supported thereon; otherwise it will be seenthatthe load would notA be discharged as eiiieiently as possible and that there would be too m'u'eh of 'a load 0n the unsupported pertionsgtheXQfg -.O ther. portions, as the swinging sections h2, Vwhich form thee'nds of the upper hopper portion, are arranged so as to remain in aat plane on account of contacting cross-beams y, which are arranged at or near'e'achend ofthe hopper. It is also desirable that means be provided when the car isusedas a gondolacar for the discharging of material through ,the sides of the car for the purpose of formingkembankments or for any other purpose.V In order to prov-ide for this, the yerticalfside sections of' the gondola car are l made of two parts-enea fixed up per section 20, which isrigidly secu red to the and the other inthe shape of see tional doors 2l andhinged to the upper per'- tion. These vertical'v swinging' side sections and to hold them in locked 22 are provided, having lugs 23 there'on adaptedtoengage with projections 24 on the.l yswinging sides when4 in closedeposition and hold such doors locked,

are arranged, as shown in Figs.10, 11, 'and 12,

to swin g outwardly,

as shown in Figs. l and 2,-hut which maybe rocked to release such projections,

the doors to be swung as shown in Fig. 10, and permit outwardly. It will be seen that when thefcar is used as a gondola car and to discharge'm'aterial through the sides the permanent ends may be removed and a dischargingfplow drawn through the car,
