y enable others skilled inthe art to which it .m

appertains to make and use the same.

My inyentlonrelates to an improvement in V coal or grain cars, the object of the same being to provide acar of this character constructed with double hoppers, and to provide doors forsaid hoppers which shall be automatic in their movements, which shall be so braced as to prevent all possibility of being forced open by the weight or pressure of the load, and so arranged as to depend no lower when open than when elosed, thus allowing the hoppers `to be built much deeper than in cars of ordinary construction; and with these ends in view my invention .consists in certain novel features of construction and combinations of parts, as will be hereinafter fully set forth, and pointed out in thel claims.4

In the accompanying drawings, Figure l is a view in side elevation ofa dumping-car emloodyin g my invention. Fig. 2 is a plan View ofthe same. Fig. 3 is a reverse plan view.

Fig. 4 is a detached view, showing the doors in their open position.

My improved car is transversely divided `into two compartments, A, by the partitionwall B, which is composed of two sections, G andD, Whichmeet at the top and diverge toward the bottom a certain distance, and then running parallel to the bottom of the carframe, the `vertical parallel portions forming the upper end walls of the hoppers E. The

e two sections C and D, being thus` placed at an angle with each other, tend to deflect the contentsof the car into the said hoppers. The floors of the said compartments are composed of the inclinesF and G, which commence at the partition B and extend longitudinally nearly the length ofthe compartment. 'These inclines are similar to the faces of the partitionB in so far `as the deilection ofthe contents of the caris concerned, and also in that thelower vertical portions form the-wallsof the hoppersE. The doors of these hoppers extend .from the extreme ends of the car-body, havcone continu-` ous pitch, and are much deeper than hoppers lofordinary construction. At the lower ends of these hoppers, and at an angle with the vertical sections of the partition B, are the l doors H; It will be readily seen that, owing 1 to the .construction of the hoppers E, the y weight or pressure on the doors will be but a small fraction ot' that on the old stylel of car, and that the liability to be forced open when loaded, so great with bottom-door cars, this case greatly lessened.

lrepresents a beam running longitudinally through` the center of the car, passingithrough the partition B, and secured to transverse end beams, J. On either side of the said beam I, parallel with and` midway between the same and the outer beams, `K L, are the beams M N, 'also secured to the said end beams, J, inany desired manner. To the said beams M is secured one end of the metal straps J', which pass around the hoppersl, and at the other end are fastened tothe beams N.- These straps, being secured to the hoppers and the beams, serve to relieve the former of a portion of the weight or pressure ofthe load within them.

Two transverse beams, O and l?, are placed doorsH are hinged the arms U,th'e inner ends` of which are hinged to a cross-bar, V. Depending slotted standards VV are firmly secured to the beams M `and N, they, slots X in "said standards forming guideways for the trunnions Y, projecting'from the ends of the cross-bar V. i Q

Z is a plate bolted or otherwise firmly secured to the brace Q. A hole orv perforation passing through said `plate Z and' brace Q forms a bearin g for the outer end of the shaft A', which passes transverselybeneath the car-` frame, the inner end iof said shaft being supported in depending bearings B' C', secured to the beam I. On the shaft A', between the bearin gs B' G',is rigidly secured a pinion, D', which meshes with a rack-bar, E', rigidly bolted or otherwise firmly secured at the lower end to the middle of the cross-bar V, the upper end of said rack-bar passing through a hole or perforation in the beam I.

To the plate Z and to one side of the shaft -A is pivoted a pawl, F', adapted to engage with the ratchet G', which is mounted on the outer end of the shaft A. A cam, H', pivoted to the plate Z, is adapted to lock the pawl F' in position when in engagement with the said ratchet G'. On the opposite side of the shaft. on the plate Z, is pivoted another pawl, I', also adapted to be engaged with the ratchet G', as will be hereinafterexplained.

K' is a projection or stop, against which the pawl 'l' rests when out of engagement with the ratchet G'. j

' It will be readily seen that by my improved construction of doors great strength is obtained, the arms U acting as braces 'to keep the doors in their closedadjustment. When the car is loaded the parts arein the positions shown in Fig. 1. \Vhen it is desired to dump the coal or ore it is simply necessary to turn the cam H' and lift the pawl F', the weight or pressure of the load against the doors forcing the same open. This movement forces the lower sides of the doors toward the depending standards ,W,' thus, through the intervention ofthe hinged arms U, elevating the cross-bar V, which is guided by the projecting trunnions traveling in the slots X ofthe depending standards. This upward movement of the cross-bar V turns the shaft A' by means of the pinion D', secured to said shaft, and the rack-bar E', secured to the cross-bar V. rIhe pawl I', when resting against the projection or stop K', being in nearly a vertical position, is, byl the jar .ofthe falling coal, shaken from the pin, and

falls by gravity against the ratchet G', and, engaging with the same, prevents the doorsfrom closing; or, immediately before unloading, it`

can be pushed down against said ratchet and the same result accomplished. When the car is entirely emptied the pawl I' is raised, and

'the weight of the rack-bar, together with that ofthe cross-bar and doors, closes said doors automatically, and the car is ready to be reloaded.

It will be observed that the doors work automatically; that, no chains being used, the breaking of such in winter-a very great objection to the present style of doorsin use-is entirely avoided, and that, owing to the construction of the operative parts, the doors, when open, hang no lower than when closed, thus allowing the hoppers to be constructed much deeper than in the present style of cars.

My improved hoppers and doors are adapted to be applied to any style of car, are adapted for use in granaries, and may be used with a single door. When an ordinary box-car is fitted with my improved style of hoppers and doors, trap-doors could be used to 'raise up, and thus present a smooth floor for ordinary freight. When used on flat-bottom cars the shaft A' is hung lower, so that the top of the rack-bar will not penetrate the oor of the car.

In view of the many changes which might be made in my improvedl device without departing from the spirit of my invention, I would have it understood that I do not limit myself to the exact construction of parts herein shown and described, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

2. The combination,with a car-body divided transversely into two compartments, each provided with a hopper, of doors pivotally secured at their upper ends for closing the said hoppers, arms hinged at one end to the doorsand at the other end hinged to the cross-bar, said cross-bar being provided at each end with a trunnion and depending slotted standards adapted to guide said cross-bar in its movements, and means whereby said cross-bar may be raised or lowered.

3. The combination,'with a car-body divided transversely into two compartments, each provided with a hopper, of doors pivotally secured at their upper ends for closin g said hoppers, arms hinged at one end to the lower sides of the said doors, and at the other end hinged to a cross-bar provided at each end with a trunnion, depending slotted standards adapted to guide said cross-bar in its movements, and a horizontal shaft and intervening mechanism,

' whereby said doors may be opened or closed simultaneously, substantially as set forth.
