*RAILWAY CAR.

' :Application filed May gijl,

My iinvention relates to hopper bottom "cars. of, the boxcar type, and it has-for its principal object the provision of a new and improved form and arrangement; of parts byavhi'ch a car can be used alternatively to .Vi'y.g0()(l advantage either asa dump. car .foirthe transportation of grain, coal, sand or,like naterial, or as a; box car for the transportation of commodities which it is necessary ;.to place in 1 position and unload by hand.

It is {another object. of =l11y 1 invention to improve devices ofthis typein sundry cleitails y'hereinafter pointed out. ,The prefe rred means by whichlhaveaccomplished my several objects areillustratedfln the drmving and are hereinafter specifically idescribed.

,That-which-I believeto benew and desire to cover, by Letters Patent isset; forth in the claims. a

In the drawing' 'Fig. 1, isia fragmentary vertical sectional view through one side portion of the floor .of ma car, transversely of, the car, showing .my. improved construction.

Fig. i2 is a top ,plan viewuof certain, of the parts shown iingFig. 1, but with the hinged-z floor closure. turned up out of. position.

;'Fig.,3 is. a side view of certain of the parts as seenfromzthe left in Fig.1; and

' vFig. l isan enlargedxdetail view being substantially a section taken on line 44 20f Fig. 1. 1 i i Beferring to the drawings, in which corresponding .parts are indicated ibyi-the same reference characters, 10 indicates one of the center sills and 11 one of the side sills of a car. 12.,indicates the door post of any approved type for the doorway at one side of the car, and 13 indicates the tread or sill of the doorway, being shown in the form of an angle iron.

For the purpose of providing for the ready unloading of grain, coal or any such product, from the car, I have provided one or more hoppers, preferably one at each side i of the car between the side doors. For this purpose. a sub-flooring is provided consisting of a plate or structure of sheet metal with depressions formed therein at opposite sides of the center sill 10, one of such depressions constituting a hopper 141, being illustrated in Fig. 1. An opening 15 is provided through the bottom of hopper 14 1923. seriarnb. 642-,00.

at each side, of the car, .with af iall e ;l 6.; in the form ofga; metal cast ng securedbyr vets '17. about the opening 15. ;As;sl1own.-in,-E g.

;1, the frame-116 is provided withgrooves shaft 22. The shaft 22 is 'mo untedi in a' bearing '23 depending fromtheframe ,16, and a bearing 24: depending from the, side silLll. The shaft 22 is alsoprovided with a hand =wheel Z5 keyed or otherwise -fi-gmd thereon,;for rotating the. shaftto move the ;door,19 longitudinally ofthe car-through the nediumof thepinion21. fAttheend of the rack formed by theteetl1 20,,a; lug or, long tooth 26 is providedadapted by-enigagement with the pinion 21, to linritthe longitudinal movementof the. .door 19.

For locking the shaft 22 against, rotation and thus holding the door 19, closed, I have providedfja key 27 (see Fig. .3) slidably mounted in a longitudinally extending,. key way formed as. apart of bearing 24. Tllhe key ;is adapted by engagement .with a SQUii-lfid portion :28 of; the shaft to hold the shaft against rotation. Nilhen it is desired to rotate the shafdthekey isnnoved longitudinally. to bring a notch 29 formed infits iupper. edge into positionsopposite; theshaft, For holding the key 27; in loCkingpcsition, the; key ,and the wall portions of thef-pocket containing the key are; provided withiopenings,therethrough for the reception of agar seal :30 or. other suitable securingmeans. ,A

pin 31 serves to hold the key'27 from withdrawal from the bearing 24.

By the means above described, a very substantial floor is provided for the car, the joints between the frame 16 and the door 19 being such as to prevent the escape of grain or other small articles. ever, it is desired to unload the car, this can be accomplished to very good advantage by the opening of the door 19, as above described.

For closing the side doorwayof the car, without the necessity for nailing strips to the door posts as is often done when *bOX I cars are to be used for hauling grain, I have provided a closure 32 hinged at its lower WVhen, how- "Ledge at the doorway." "33, designates a simi- 18.1 closure -at the other side of the car. With these closures turned upwardly and latched in verticahposition, they provide supplemental or grain doors, some such means being ordinarily employed-1n addition to the usual side doors when the car is loaded with bulk freigh'tof a granular chatf acter. 1 -10 poses, the closures are-turned down into horizontal position, as shown in Fig. 1, and

" serve as part of the'car flooring to cover the hoppers; the upper faces ofthe closures 32 and '33 in this position'being preferably flush with the upper surface of the remaining portions of'the floor of the car.

p The guideways or grooves 18 in the'frame openings for the car 'seal'might not register.

'1; Awrailway through the floor thereof,a door formed of I claim; 7 r

car having an opening metal slidably mounted in position to .close said'opening, teeth formed on said door, a"

' pinion meshing with-said teeth, ashaft con 'nected with said pinion for rotating it to ,I move the door, a key slidably mounted adjacentto said shaft and adapted'when in operativeposition to prevent rotation of the shaft, and'releasa ble means for locking the key imposition.

'- "-2; A railway car having an opening *through the floor thereof, a door formed of metal slidably mounted in position to close said opening, teeth formed o'nsaid door, a pinion meshing with said teeth, a shaft con-' nected with said pinion for rotating 'it for 1 moving the door, a key slidably' mounted adjacent to said shaft adapted by engagement 7 'With'a fiat face portion of the shaft to hold the-shaft against rotation and-provided with a notch which can be brought slidably into position opposite the shaft for permitting rotation of the shaft and an opening" 7 through the key for the insertion of a car When the car is used for other pur seal for-'holdin the key in lockingposition.
