I a A Ffrei'ght car built in accordance with thisinvention comprises a main supporting frame 10' adapted tobe, mounted upon 36 trucks11 in a conventional manner. The ,frame 10 includes a pair of central longi- Vtudinal stringers '12, lateral longitudinal stringers 13, and endvgieces 14. Centrally .-a series of vertical struts or ts 15 and 16, the latter located neenthe. on 'tudinal center of the car and tot e stringers 12.

i The body of the car 18 is of the inclined 'orf'hopper bottom type and is supported upon the, frame 10, said body 18 having the inclined bottom sections 19 inclined toward each othe r toward the center of the car, the plan'esof said inclined bottoms intersecting the generallplane of'the frame '10 substan-o Specification of Letters'Pa tent.

tially'midway between the ends of the body 18 and its transverse center. The lower extremities of the bottoms 19 are spaced apart in a well known manner and 'them'aterial carried 'by the body and to be supported therefrom is intended to be discharged from the inclined bottoms through said space. I

The housing 17. above referred to is of substantially an inverted V-shape and 'is rigidly supported upon the upper ends of said upper ends being shaped to conform to the said sha e of the housingintp the inner or lower si e ofwhich the posts extend as indicated in Figs. 2 and 4. The lower edges of the housing extend over the lower ends 7 of the bottoms 19 and'are spacedtherefr'om "'eh-utes being on each side of the central side of the transverse center of the car. In other words thereare four of said chutes provided as indicated, although it is to be in thisrespect. The four several discharge chutes are normally closed by upwardly. movable gates or valves 20. The valves 20 normally rest when in closed position; upon thebottoms 19 and are adapted to swing upwardly in arcs of circles just below the horizontal plane and in parallelism, although the exact location thereof may be varied if desired. Connected to the rock shafts 22 are pairs of flcxible connections 23 indicated as chains, the upper ends of the chains are connected to the respective shafts 22 by any convenient means such as eyebolts, and the lower ends thereof being connected to the several valves 20', preferably at the outer or up er ed es so as not to interfere withthe 0w 0 material through the posts 15 and 16' above referredtoythe' s o as to provide discharge chutes; two of said.

stringers 12 and likewise two being on each' lower edges of the housing 17. As a preferrecl means for mounting said gates orunderstood that the invention is not limited V 22 are shown as being in a substantially the chutes nor the operation of the chutes.

on their pivots. Each rock shaft 22 is 4 adapted to be operated by a wrench or-crank in a well known manner to be applied on 5 an outwardly extended polygonal end there 7 of; A ratchet wheel- 24 mounted thereon is adapted by cooperation with a pawl 25 to:

retain'the shaft in any desired ad usted posi-' tion so as to maintain the valves 20 shown,

10 if desired. I

By the construction described it ispos sible for the car to be discharged or emptiedof as-much or as little of itsload 'as desired and for the flow to vbe stopped by simply releasing the pawl from its ratchet permitting the valves or catches to gravitate to the bottoms l9 automatically cutting 01]? the flow. Again, another advanta e of this construction is that there areno oors' 20 or gates to swing below the'car bottom, an

objection frequently met with in devices of this "character; The gates being swung outwardly on arcs of circles are easily 0 erated to open,-and yet there is no possib' ity for the weight of the'm'aterialto'causethen to. open when not desired. The gates may all be opened or only part of them as may be desired at any onetime.

That portion ofthe car body between. the

3 0 stringers 12 is bridged by strips 26. The

mar ms of the housin '17 are preferably provided with flanges 1%, whereby it is impossible for material to sift through between the edges of the housing and the walls of 85 the car body and to; be lost. Said flanges may be integral-with the housing or may be made separately and secured to the several parts by riveting or in any other suit able manner. The flanges also serve to 40 stren hen the structure, the same being subjecte to rough usage in ordinary practice.

While there has been described herein a' preferred embodiment of car bodyto which the operating devices are attached, it is to be r understood that the operating devices may be applied to many coal cars already in use without departing materiall from the spirit of the invention embraced t ereby'.

Havin thus described the invention, what is claime as new is:

1'. Thehereinde'sc'ribed car comrising a car body having bottom.

inclined toward each other andspaeed apart, v

a housin extendingtransversely of the car body an covering the said space ,.lthe lower" edges of the housing being spaced" from. the said bottoms and forming discharge chutes, a-series of valves below the housing and resting. normally upon the said inclinedbot- [toms of the, car body, and -means operative within the housing to cause the elevation and opening of the valves upwardly from said normal posit-ion;

2. The hereindescribed self dumping, coal car eom'prisinga car body'having an --in-- elined bottom, a housing extending transversely of the ear and projecting over the lower edge of the said bottom, the lower edge of thehousing being spaced from the bottom forming a discharge chute, an are shaped valve pivotally mounted below the housing and resting normally upon said bottom closing: said chute; a transverse shaft extending within the housing, and a flexible connection between the valveand the shaft, whereby on"rotation ofyt-he shaft and who will-be lifted tolopen the. disehar'gefchutex '3. The herei'nde'scr'ibed coal car comprising a body havingjnclined bottom sections and transversely of the car, connections be- 9 tween the rock shafts and the valves, and

means to control the operation of the rock shaft, substantially as s'et' forth.
