1910, Serial No. 578,592. Divided and this application filed August 21,1912; Serial No. 716,122.

To all z't may concern:

' Be it known that I, CLEMENT Gr. HARRING- TON, residing at 915 Olive street, St. Louis.

Missouri, and being av citizen of the United States, have invented certain new and useful Improvements in Dumping-Cars, of which the iollowing is a full, clear, and exact do seription,-such as will enable others skilled the'jart to which it appertains to make and 510 to use the same. 4

.This application is a divisional application of Serial No. 578.592 filed August 23rd, i910, reference being had to the accompanying drawings which illustrate the preferred form of theinvention; though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications'thereof will occur to persons skilled in the art. i

In said drawings: Figure l is a view in side elevation of one-half of a car embodying the features of the present invention. the undisclosed. half being a duplicate of that.

disclosed. Fig. 2 is a transverse, vertical section taken on the plane indicated byline 22 of Fig. 1 Fig. 3 is a longitudinal vertical, fragmentary section taken on the plane indicated by line 3-3of Fig. 2, and looking in the direction indicated by the arrow. Fig. 4 is an inverted plan view of one half of the ear showing the hoppers with the door operating mechanism therefor. Fig. 5 a detail hereinafter described.

This invention relates to improvements in steelhopper cars, and particularly to such as are provided with levcr actuated dumping.

' valves.

Among the objects in View are simplicity 0 and efficiency of manipulation of the operating parts as well as the effective distribution of strains.

Referring to the drawings by numerals, l, l'indicatcs the longitudinal plates of the center sill, and 2,2 the side girders, which latter form the sides of the car. i

The car may be divided into as many hoppers as preferred, but for the purpose of illustration the car is indicated as being provided with four hoppers, two being arranged side by side in each half-length of the car;

. and each hopper consisting ofthe respective side or side girder 2, and front and rear inclined floors 3 and longitudinally extending laterally incl'nied floors, 4, 4. Each side girder 2 depends below the outer floor 4 of the respective hopper, and intermediate of the length of said floor are arranged castings 5-6, spaced apart and each riveted to the side girder 2 and extending to and affording a support for the inclined floor 4; Each casting 5 preferably consists of a hollow casing, made up, as bestseen in Fig.6, of side plates 5 and a connecting crossweb 5" extending along the inner inclined edges of the plates 5 along the upper horizontal edges thereof, and down along the outer edges thereof, the inner lower edges being left disconnected. and the said Web-5f" receiving the rivets with which the casting or casing 5 is connected to the side girder 2'. Each plate 5'.- of each casing 5 is formed at. its upper inclined edge with a notch 6', producing an ear 7, and these two cars of each casing are perforated for receiving a pintle or hinge bolt 8. Thecenter plates 1 are connected-at their upper edges by cross webs or plates 9 5 extending downwardly between the sill' members and united thereto. Upon the webs 5L4) is arranged a V shaped cover plate 10 riveted or otherwise suitably secured to the plates 9 and having its opposite legs extending downwardly across the u per edges of the center sill plates 11 and forming the inner inclined floor 4 of the adjacent hopper. The upper edge of each plate 1 is provided an angle bar 11 riveted to the plate 10. said angle having outstanding horizontal flange. Between each of the plates 1 and the contiguous floor 4 are arranged castings or casings 5 constructed exactly like the casings 5 and supporting the contiguous floor 4. The floors 4 terminate a considerable distance above the bottom central point of respective hoppers and the remaining portion of each hopper is completed by a pair of valves or doors 12,

riveted to the plate 1 and extending to and door 4 and is provided about all of its edges with adownwardly extending flange 13 lying. when the door is closed, within the notches (3, at the upper edges of said d0"( i'rs A pair of binge straps lat ll. riveted to the under side of each door are designed to enthe pinl'les 89 in the ca ings 5 and 5 for pivotally sustaining the door in engagement with the pintles, each strap 14 ektcnding between the pair of'sidc plates 5 of the respective casing carrying the given pintle 8. Obviously, as many of the casings 5 and 5 and binge straps 14 may be provided asdesircd, but a pair for each door is usually sutlicicnt. The flange 13 along the lower edge ofveawch door 12, is preferably formed with a downwardly turned bend 13' adapted to snugly fit a correspondingly shaped. portion of a pressing 15 extending throughout the length of and centrally 'beneath the open bottom of each hopper. and terminating at its ends in end flanges 16,16, riveted to the depending cross plates or bulk heads 1? at the ends of the open bottom of the hopper. .The conformity of flange l3 with-the transverse angular form of the pressing 15 insures a snug, close fit of the doors 12, providing against springing of the parts or other openings afi'ording opportrtnity for leakage.

Each door is supported in its closed position by a pair of bell crank levers 20, 21 carrying, at their ends next the doors shafts 19 on which are supported rollers 18 bearing against the outer or under faces of the doors, Each bell crank'ispivotally' supp0rted, the pivot comprising preferably a fixed pin as 22 projecting. from a suitable bracket 22 carried :by the respective bulk head 17.

The bell crank levers 21-21, carrying rod 19 forthe outer door 12, are continued, in the form of flatbars 23, and the outer ends thereof project beyond the side girder 2 and are twisted, 'as at 24, for presenting their flat faces toward the outer face of the girder.

These levers are connected together by a tie f rod The extensions 23 are bent approximately at the point of the twist 24.- for producing an angular portion adapted to extend. when the doors are in closed position, about the horizontal flange. of the angle bar 2 of girder 2. The outer ends of the extensions 23 are preferably slotted and adaptedfor engagement wit-h locking members 25- -25 projecting outwardly from the side fa e of the side girder 2. The locking members extend thro-u h the slots and suitable cotter pins 26 retain the levers in raised position. It is to be noted that when the parts are in closed position, the shaft 19 is .in that alinementwith the pivots 22, com

monly known as a dead center, so that the pressure exerted on ea. hot the doors 12 ill betaken up directly by the pivots 22 with no appreciable pressure on the outer portions of the levers 21, such pressure he door 12.

ing taken up as a direct longitudinal stress by the short arm 20.

The free arm of each inner lever 21 is pivotally engaged by a depending link 27, said link at its lower end pivotally engaging a slide bar 32, a rod 28 being provided for and connecting the links 27 of the pair of inner levers 21 for each inner door .12. The inner ends of bars 32 are fixed to slides 29 carried on and engaging ways 30, each slide having an upper and a lower flange lapping the upper and lower edges of their respective way 30. A similar slide 31 slidingly engages each way 30, and is spaced thereon ontwardly from slide 29 and connected with slide 29 by the bar 32, said bar being bent or otherwise constructed at its outer end to form an operating handle or grip 33. \Vhen the door is closed the links. 27 extend substantially vertically above the rod 28,

thus practically locking the connected levers 21 against rotation. Near the outer end of each bar 32, the. same is formed withan aperture 32' registering when the door 12 is closed, with a corresponding openin 30 formed in way 30, through which registering openings is passed a removable key or other suitable locking device. 32" for locking the bar 32 and more effectually retaining the parts in a closed position. Each bar 32 may be of any desired length. and each link 27 preferably of a length for causing; the rod 28 to lie beneath pressing 15 when the innerdoor 12 is open, asseen at the le it end of Fig. 2. Each Way 30 braced and supported by stays and braces 3t. 34', extending downwardly from parts of the car body, and each way 30 prefer-ably consists of a flat strip which extends across the entire width of the car, so as to serve'as a way for the slide of the inner door 12 of each of the hoppers of the laterally juxtaposed pair.

For guiding and enabling forcible opening of the doors, when frozen or otherwise stuck in closed position, by movement of bars 15), each of said bars extends through and travels transversely within a pair ot guiding brackets 35 fixed to the respective At the lower terminu ol move ment of each bar 19. the outstanding tlangc or web of an angle plate 34' is arraa wd. said angle plate being comprised in the lu-ae-ket 35, so that the bar snstaincd against eXf c'ess downward movement. Obviously, as man brackets may be provided as desirer but two such brackets spaced apart along the door are usually sutlicient for each rod 19.

lt is to be observed that each T stress of the load is thua distributed from 1 team;

' the hinges directly to. the sills almost-enti'rely as a downward-component and with but a minimum of lateral or burstingstrain. Obviously, while the means of attachment for various parts has been herein mentioned the levers with the doors, insures ease and certainty of operation.

, Either door 12 of any hopper may be manipulated independently of the other, whereby the entire load may be discharged. near the center of the car, by openingonly the inner doors, or

approximately one-half of the load may be dimharged' at each side of the car, by.open-.

' ing only the outer doors, or the load may be discharged directly downwardly by opening of thedoors simultaneously. The simultaneous opening of both doors of one hopper uncovers the openings in the bottom 1 s j with a car body and a dumping door thereof; that hoppeigas indicated at the left of Fig. 2, and'its load can thus'be practically instantly discharged. To close the outer doors, it is only necessary tolift the projecting. ends 23 of outer levers 21 into engagement with locking-membe'rs25, which lifting movement, causing travel of rollers 18 alongthe-under side ofthe door,-will swing said door closed, and the retaining pins 26 may be positioned for locking the parts closed. Toopen said doorrequires only the i removal of the pins 26' and the starting of the outer. ends of the levers downwardly for moving bar- 1'9 from theline of dead center,

whereupon the door will be released and will open by reason of the weight of the sustained load or maybe forced open by engagement of'the rod 19 with the guides 35.

The action of t he inner set 'oflevers, for operating the inner door 12, is the same as that just,described, except that the slide bars 32 are shifted longitudinally in lieu of the swinging movement of the outer ends of the outer levers, the links 27 transmitting movement from slide bars 32 to the inner levers 21.
