.To all whom it may cmtcern:

Be it known that we,HARRY STILLsoN HART and OTTO W. MEIssNEE,citzensof the UnitedA The principal object o f theinvention is to.

provide a simple, economical, and efficient hopper-bottom dumping-car with means to facilitate the discharge of materials therein.

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

The inventionV consists, principally, in a hopper-bottom dumping-car, in which there are combined a supporting-frame portion, a V-shaped hopper portion extending longitudinally of the car and with its apex arranged l at or near the longitudinal center of the car and the bott-'om portions of which are pivotally secured to the underframing of the car, so as to provide Ya maximum opening and facilitate the du mping'of the materials substantially as hereinafter set forth.

The invention consists, further, in a hopper-bottom dumping-car provided with, a supporting-.frame portion,`a.Vshaped hopper portion extending longitudinally of the v car with its apex arranged at or. near the longitudinal center` thereof and the entire dis- `tance between the inner axles of the cartrucks, the inclined side portions of which are divided into upper and lower portions extending above and below the underpinning of the car, with the lower portions pivotally secured to the underpinning, and means for closing both of such bottom portions by and during one and the same operation, substantiallyas hereinafter set forth.

Theinvention consists, further and nally, in the features, combinations, and details 72, a 'plan' view of the same; Fig. 3,.a longitudinal sectional elevation taken-on line 3 of Fig. 2 looking in the direction of the arrow; Fig. 4, a cross-sectional view taken on line 4 Aof Fig. l looking in the direction of the arrow;

Figs. 5, 6, and 7, enlarged sectional details of parts more fully hereinafter described.

I n the art to which this invention relates it' is well known that dumping-bottom cars lhave become a necessity with the large raillways of the country and that in the use of vV-,shaped hopper-bottom cars which are selfdischarging, particularly those known as the Rodger type, it is desirable to have the hopper so constructed and arranged that it may be used for discharging ballast between the tracks in the desired shape-viz., by the use of one swinging portion. It is also Well known that whenv it is made in this way it has objections, in that it cannot be used to advantage for the discharge of other materials, such as coal, for the reason that such material is apt 4to stick in the dischargingopening. It is therefore desirable to provide this type of car with maximum openings and so arrange it that it may also be used as the older Rodger` type with minimum openings to carry and discharge ballast, all of which lwill be understood and appreciated by those skilled in the art. 4In constructing a car in accordance with these improvements We make a car-body the underpining of which is provided With fside sills a, intermediate sills b, andnon-continuouscentersills c. Theunderpinning hassecu'red to it upright or vertical side frame portions formed of stakes d and upper portions @secured thereto. End boards or portions f arel also provided and secured to the underpinning, so that all of such parts not only assist in carrying the load, butinthe stiening of the structure towithstandjthe stress and strains incident to ordinary use.

To provide means by which the load may be carried, .we provide a V-shapeddumping- IOO hopper portion extending longitudinally and with the apex thereof arranged below the underpinning and at or near the longitudinal center of the car. This hopper` portion is formed of inclined sides divided into two parts-upperlixed parts g, the lower portions of which are secured to the intermediate sills and the upper part to the side framing of the car, and lower swinging portions h and i, which in turn have their Lipper ends pivotally secured in metallic brackets o, attached to the lower inner edges of the intermediate sills-so that when the parts are in their closed or operative position, as shown particularly in Fig. 4, they are arranged at substantially the same a-ngle, though in broken or dierent planes.

' From an examination of Fig. -t it will be seen that both of the lower swinging portions may be swung open, so as to provide a maximum opening between the intermediate sills, and thereby facilitate the discharge of coal or loose bulky freight. It oftentimes becomes necessary,however,toprovide meansby which one of such doors may be held closed while the otheris operated,soas touse the carasaRodger ballast-car-that is,a carin which one lower portion is movable and the otherimmovable.

' For this we provide onelower portion with a l the further swinging portion h is adapted to roll.

be opened and closed, as desired. It is of course desirable that some simple mechanism be used which will effectually permit both of such lower swinging portions to be opened and closed by and during the same operation. To provide s uch mechanism, a single rockshaft l is used and rotatably mounted in the framework of the car. To this rock-shaft is secured a plurality of chains lmwhich are also secured to the lower free edge of the farther swinging portion of the hopper, as shown at n. The lower ends of the near swinging portion of the hopper are provided with idlerrolls 19, one for each chain, each of which is mounted in and between the metal bars q, which are tied together by means of the bolt r, the bolt acting as a'guide to keep each chain in engagement with its particular idler- By this arrangement it will be seen that when the chains are wound up both of such swinging doors are closed during one and the same operation, and when the rock-shaft is free to rotate both of such doors may be opened during the same operation. Again, it will be seen that when the hooks 7c are in engagement with the eyebolts j on the near swinging portion of the hopper such portion will remain stationary while the other swinging portion is free to operate. The rock-shaft may be provided with ratchet-and-pawl mechanism t, (shown to the right of Figs. 1 and 2,)

which is shown, described, and claimed in Patent No. 716,075, granted to Otto W. Meissner the 16th day of December, 1902, which controls the operation thereof and needs no further description here, in that it forms no material part of the invention.
