HERBERT T. HERR, OF DENVER, COLORADO, ASSIGNOR TO THE HERR DUMP CAR COMPANY, OF DENVER, COLORADO.

Dun-CAR.

To all whom. 'it may concern:

Be it known that I, HERBERT T. HERB, a citizen of the United States, residing in the cit and county of Denver and State of Co orado,v have invented certain new and useful Improvements in Dump-Cars' and I do declare the followi to be a ful clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom anying drawings, and to the letters and gures of reference marked thereon, which form a part of' this specification.. q

My invention relates to an improvement indum ing cars, and is more particularly ada te to Vthe constructive type of dump car dy having a centrally disposed longitudinal truss beam or A frame, with end lloors inclined downwardly, at a suitable rtion of thecar body; on `to the bottom o which are secured two or more longitudinally ed dumping or discharge doors.

novel and important feature embodied in my invention, which I believe to be Vge.- nerically new, and a radical departure from existing details in this class of construction, is the means whereby I secure the discharge doors to the bottom'ol the car with a sepa-y rable liingeloek by the use of which I am enabled to release the disehargge doors from engaged members upon the opposite side of the doors act as a hinge, around which thereleased doors swing, either inwardly or outwardly as theccasc may be.. This arrange-A mentl enables mc to disc-ha the entire load f upon either side of the trac ,'or between the rails of the track, or iii part upon either side of the track, or `in part between the rails of the track and upon either side of the trackV as conditions may require. 'l'lie separable hinge-locking construction embodies'a fur.

ther novell end important feature, inasmuch as it will take up a limited amount of sag in the doors, liable ,to arise in practice, due to war iing, ete., or to failure of the winding mee ianisin to carry the doors completely home, `the locking pins be' formed with a suitable sloped point to e ect this move` ment.

M v construction further atords ,in either of these several dumping positions a maximum area of open dumping space enabling me thereby to discharge the. entire Bpeeieation of Lettera Patent. l

load veryquickly, if so desired, entirel utomatically, by gravity, requiring no iand slioveling of any portion of the load. V

My invention comprises a winding-,mechanism whereby the released doors may be lifted and re laced in osition, and properly secured by t e hingeocks for reloading the car. Considering the several positions into which the doors may be dropped, from an of which they can be replaced by this win ing. attachment, the construction is comparatively quite simple, efficient and durable.

My invention further comprises a foot- 'I brake mechanism, mounted upon the winding mechanism whereb the operator is enab ed to fully control t e speed with which the loaded doors are permitted to drop, thereby avoiding the danger of dama 'ng the construction from the impact of the eavily loaded doors, were they ermitted to drop freely upon the parts. his foot-brake attachment also enables the o rator to govern the distance to which the tors are permitted to o n, and with an interlocking pawl and ratc et suitably mounted upon' the winding mechanism, secure them in any partly opened position, when desired to particularly control the discharge of the material being dum ed.

A ditional detailsv as to the construction and operative functions of my invention will be more fully hereinafter set forth.

vReference is to be had to the accompanying drawings forming a part of this specification in which: Figure 1 is a reduced sende, outline, side elevation of the preferred type of a two-tloor y dump car, showing in general outline my attached construction, the centrally disposed discharge doors being shownin the raised or closed posit-ion; the released or open position of the saine being shown in broken lilies.V A portion of the side of the car at the operative end is broken away in this fi re to more clearly show the arrangement ogltlhe separams of a car bodyV ble lunge operating levers and winding or tral longitudinal truss-beam, being in cross section line 7-7 of Fig. 1, viewed inthe direction of the arrow, showing the central 1on- 'tudinal truss beam and the side channel earns, the attached discharge doors, secured by the hin e-locks, upon their inner edges to the sides o the central truss beam, and upon their outer ed es to the side channel beams and showing a so a ortion of the door raisin crank shaft. 1g. 8 is a detail view in si( e elevation of one form of the hinge-lock, designed to be secured to the side channel of the car body, being shown in engagement with the end of a door-beam hinge. Fig. 9 corresponds with Fig. 8, showing the hingelock in end elevation and a part of the doorbeam hinge in side elevation. Fig. 10 is a corresponding view of the door-beam hinge and hinge-loc designed to be secured to one side of the central truss beam. Fig. 11 is a detail end elevation, and Fig. 12 is a corresponding side elevation of one of the joint pins of the liinge-lock, with the connecting yoke piece, whereby the pin is secured to a section of the connecting bar as shown in Fig. 8. Fig. 13 is a detached detail view in front elevation'of the hanger portion of the hingelock shown in Fig. 8. Iigs. 14 and 16 are respectively, end and side elevations, and Fig. l5 a corresponding plan view, of an end of a door-beam hinge.

Fig. 18 is a corresponding view with the parts 1n position showing the door-beam hinge reeased. v

Similar reference characters throughout the description indicate corresponding parts in the several figures.

In this present application I describe and illustrate, merely in a general way, a construction of dump car adapted to embody my invention referring specifically to only so much of the car body construction as is necessary to enable one skilled in the art, to fully and clearly comprehend the construction, application and cooperation of my invention.

Referring to the drawings, briefly stated, I provide in the car body construction a censection an A-shaped plate member A, Fig. 7, the lower edges of which are transversely supported by a number of struts A formed of angle bars which are secured to the sides thereof, on a transveise line with the door beam hanger-locks as shown in Figs. 2 and 7, and side channel beams or car sills, B. B., sloping end floors C. C., Fig. 1, inclined downwardly ata suitable angle from the ends of the car body toward the central portion thereof, at the termination whereof are suitabl disposed transverse beams D. D. Figs. 1 an( 2, thus forming in the central bottom portion of a two-door c'ar body between the lber of transversely dispose( sides of the central truss-beam member and not limit myself to this number of openings and doors, since under certain conditions a greater vnumber of doors, with probabl diminished areas of openings would be diissirable. Referring to Fig. 7, I indicate in broken lines the several positions into which the doors may be dropped, also iiibroken lines the several corresponding positions from either of which the doors can be carried up to their respective closed ositions by two longitudinally disposed cran shafts 10, 10.

In diagram Figs. 3 to 6b, Fig. 3 shows the doors set to discharge the load to the outer sides of the track; Fig. 4 to the inside of the track; Fig. 5 partly to the right hand side and partly between the track rails. Fig. A6 partly to the left hand side and partly between the track rails. Fig. 6 with the door F released, and the door E closed, Fig. 6h with the door E released and the door F closed; Figs. 1, 2 and 7, all doors in closed position.

I secure the doors to the car body by a suitable number of hinge-locks, 1, 1 shown iii enlarged detail Figs. 8 to 16 inclusive, comprising the main hanger, secured b a flange portion 1 to the side channels B, and t e central truss beam A. Cast integrally with this flanged base and extending downwardly from the side thereof, are two longitudinally bored joint-pin lugs 1b, upon the top of one of which is formed aA longitudinally slotted boss 1 which serves as a guide or carrier for a connecting bar 2, mounted upon which, ad-

jacent the hinge-lock hanger is a yoke-piece 2 carrying a ioint-pin 2", designed to register with, ani be engaged by `the bored hanger lugs 1h.

The hinge lock shown in Fig. 1() is suhstantially a du licate of that shown in Figs. 8 and 9 descriged above, excepting that on this the flanged base 1a and the bored jointpin lugs 1b are disposed relatively at a slightl different angle, and the flanged part 1 is orined double or as a jaw-flange, designed to be secured to, and'conform with the'sloping sides of the central truss beam A. On to the under sides of the discharge doors E and F are secured a corres onding numdoor beam hin es 3, 3, the ends of which, )rejecting slig itl beyond the sides of the ioors, are forme into joint-pin eyes, or hinge ends, 3, 3 designed to register with the slotted spaces orined between the bored hangerlugs 1b, 1h of the hinge-locks, in which posi' tion they are engaged by the eoperating jointins 2", as shown in ligs.8,9, l() and 17.

Re erring tov Fig. 12it will be seen that/the -From the4 above it will end of the joint-pin 2b is tapered at a suitable angle 2c to permit of its taking-up to some extent, a sa ging door hinge 3", when the pms are thrust ome, and engage the hinge end between the hanger lugs 1", gy moving the connecting bars, 2, 2, 2, 2. hese bars are suitabl disposed, one each adjoining the side sills B, of the car, and two beneath the cer: tral truss beam A, each mounted in their respective hanger slots f1, and carrying the several joint-pins 2b as shown in Figs. 2 and 7. The extreme end of 4each bar'2, 2, 2, 2 adjoining the operativeend of the car is jointed, respectively, to vertically disposed o erating levers 5,'6, 7 and 8 as shown in igs. 1 and 2, each mounted on a suitable bearing 5b, 6", 7b, or 8. 'Upon the side of each lever, above the bearing is formed, respectively, a stud 5?, 6, -7 or 8, each of which is engaged by a self-acting retaining hook, 4, 4,4, 4, as show n in Figs. 1, 17 and18 positively securing the levers in the position corresponding with the normally engaged position of the'joint pins 2b, thereby preventing the accidental disengagement of the joint pins` and release of the discharge doors.

The mechanism hereinbefore described comprises the entire construction required to retain two discharge 'doors in their closed positions, or to manipulate the attachments in a way to effect any of theaseveraldumpingl positions shown.

-It is im o rtant that the o eratorbe enabled to re ease the doors wit out havin to leave his osition on the'operative en of the car. l) rovide means whereby this can be done` o release the doors and discharge as shown in Fig. 3, which is outside dump, the operator disengages the locking pawls 20, -20 from the ratchets 21, 21 mounted on the winding crank shafts 18, 18, Figs. Vl and 2, hereinafter described, and therespectivc retaining hooks 4,l 4, and

moves the outer operating levers 5 and 8 from the, position shown in Fig. 1,-in full lines, to the position shownin broken lines, thereby withdrawing the respective jointpins 2h, as shown in Fig. 18, releasing the eorrespondingdoor beam hinges 3 upon the outer sides of the doors. The ins and hinges'upon the inner lsideslof t e doors, remaining in engagement, as shown-in Fig. l0, forni the hinge joint around which the discharge doors swing, as shown in Fig. 3.

liended howthe several discharge positions may be effected, by moving the corresponding operating levers 5, 6, 7 or 8. It will 'also be seen Jthat all `doors can be entirely disengaged and `'conveniently moved aside, making'all part-s of the de tail construction readily accessible to mechanics or car repairers, if necessary.

The mechanism for raising the released be readily compreinto the closed, reloading position, as shownin Fig. 7, is provided in` du ilicate, cach construction copcrating witi itsl correspending door, located upon either side of t e central truss beam and inasmuch as the constructions are identical a description of either, will apply to both.

In a two-door car, as shown in Figs. l and 2, a longitudinal crank shaft l0, has formed thereon Aa crank .10", slightly longer than the door. This crank shaft is mounted in hanger bearings 1.1, Il which are secured beneath the car body adjacent the ends of the discharge door, substantiallyin a plane' beneath the longitudinal center of tho door, as shown in Fig. 7. Mounted upon the cranks are a number of antifriction rollers 22, 22 correspondin with the number of hinge beams secure( upon each of the dischargedoors, which in Figs. l and 2 is shown to be four, this is optional, however, as a greater number may be found necessary to meet the requirements of practice. The rollers are placed in position to register with the hinge beam irons against which they roll when the door is being raised by the crank, a separate rolling plate may be used if desired. l

Referring to Figs. 1 and 2 it will be seen that the door swings freel between the crank arms 10h permitting the crank lO to assume a position beneath the same when the door is dro ped regardless of the position occupied Y the crank rior to the releasing of the door, orwhe't er the door be released from the inner or outer side. And it will also be seen that Vthe door can be carried back to the closed position by rotating the crank in the corres onding reuired direction. It will also )cobserved t at the crank forms a hanger the released door, assuming a .position at right angles thereto with the weight and force exerted longitudinally through the crank arms l0", sional forces upon the crank shaft, by lthe weighted door, which otherwise might tend to give the same a permanent set.

In Figs. land 2 areshown secured upon the end meshes with a bevel pinion 13 mounted upon the lower, end of an upwardly inc-lined l countcrshaft 14, which is suitably supported in bearings l5 and l5, adjacent the operative end of the car, disposed, beneath and at an angle nearly parallel to the slope of the'v inclined end floor (l. Upon the upper cud of this counter-shaft 14 is secured a bevel gear wheel 16 which mcshcs a ith a bevel pinion 17, which is keyed upon thc end of ii -short horizontal winding crank -shaft l.'

which f orms ii part of thc crank winding or' door raising mechanism. This winding discharge doors, rom any of the several l crankshaft is mounted and rotates lrccly in or stop for i thereby eliminating -torizo bearings 19 and 19, both suitably'seeured upon the operative end of the car body. Formed upon the upper side of the bearing 19 is a boss 19h, upon which is mountedla right and .left locking pawl 20, designed to engage. a ratchet 21, which is securely keyed upon the winding crank shaft 18, adjacent the. hand-crank 18,

The above described construction comprises the attachments adapted to secure, release and raise the discharge doors, roviding for the opening of the doors to t eir maximum limit, permitting of the ra id discharge of the load, ordinarily desirab e when dumping coal or ore into bins or chutes. In practice, however, it is frequentlyY necesssary that the opening of the discharge doors be controlled,| articularly in the case of han dling grave or ballast along the line in road work, where it is desired to distribute the same from a moving car with the doors partly open. I accomplish this result by the use of a foot-brake construction.

Referring to Figs. 1 and 2, a band brake wheel 23, of the usual construction is secured upon the counter-shaft 14, from which the Afriction strap .24 is secured to a short crank arm 25 formed upon a -transversely disposed rock-shaft 26, suitably mounted upon the car frame, upon the ends of which shaft are formed two foot-tread arms 27 which carry atransverse tread board 28, located adjacent the hand-crank, and accessible ,to the operator when operating eitliei' the inner or outer release levers. By appl 'il'ig the brake the dropping of the door can be controlled and brought to a stop in any part of the swing, b f the engagement of the brake-'retarded cran shaft '10, beneath the door and when so stopped can be securely retained byinterlocking the pawl 20. and ratchet 2l, upon the winding crank sliatt.

Referring to Figs. 3 and 7, it will be seen that to raise the released doors from the osition shown in Fig. 3, which is outward vt iscliarge, the opcratorgrasps the cooperating hand crank 18, hanging downward as in Fig. I, and rotates it outwardly, as indicated in broken lines in Fig. 2. ln Fig. 4 whieliis inward dum i, rotatetlie Arespective hand crank inwardly. ln Fig. 5, the left side door F heilig inward duni i, rotates the cool-wrating crank inwardly, tlie r 'ht side door' E being outer dump, rotatest ie right ,side-crank outwardly. 'lhus it will be seen that the direction of discharge is a guide to the required movement of the hand crank to rcturn the door, conse. nent-ly even though my construction embot ies this plurality of dmiiping positions, confusion on the part of the operator in manipulating the parts is not likely to arise.

ln view of the foregoing description a brief coniicctet-l ,refere'nceas to the operation of the mechanism, will be readily undeistood.

Let it be supposed that the operators wish to dump a load from the two door car, inwardly, as shown by diagram Fig. 4. Disengaging the pawls from the .winding shaft ratchets, and the respective retaining hooks 4, 4 from the inner operating levers 6 and 7, these levers are'drawn outwardly from the car to the extreme outward position as shown in broken ,lines in Fig. 1, disengaging the door hinges upon the inner sides, and permitting the doors to drop as shown in `ig. 4, discharging the load inwardly. The load having been discharged inwardly with the operating levers still in the outwardy position, corres onding with the released position of the liinge members, to return the open doors to the closed position, the operator proceeds to turn the hand crank 16, inwardly, adjustin the pawl 2() accordingly in engagement witii the ratchet 21 upon the winding crank shaft. When the empty doors have been carried up to the closed position, and retained by the pawl and ratchet, the operating levers are thrown inwardly, carrying the hinge-locking mechanism into positive enga ement with the door beam inges as has een shown, while the retaining hooks 4- 4 automatically engage the respective lever studs 6 and 7 securing the levers and cooperating door hinge construction in the closed door position,
