DUMP-CAR.

Application lcd December 1, 1909. Seria1 No. 530,742.

To all whom 'it maf., concrn: A

lie it known that l, -WJLLIAM trl.. OLnnN,

a citi-zen of the United States, residing at AJoliet, in the county ot' virili, State ot' Illi- 5 nois, have invented certain new and useful Improvements in Ihilmp-Cars, of which Ithe following is a specification, reference being hadto the accon'lpanying drawings.

This invention relates to improvements in l dump ears of' the same general type shown and described in'Letters Patent- No. 929,104, dated July 52T, i909, granted upon my a pplieation, in which, as there shown, the `ear-body is providedv with two large hopperl like chambers the lower ends of which are closed by a4 plurality of swinging doors so arranged as to discharge material toward opposite sides of the car.

One oi' the. leading objects of the present invention is to provide novel closing means tomvhich all the doors at a sidelof the. car are connected and which will compel each of said doors to be brought to a perfect closing .position and ready to be locked, and this too regardless of whether the doors move exactly in unison orfby reason of the lifting chains being attached uncqually or for other cause, some one. or more ot the doorscomes toa full closing position after the other door or doors has or have been closed. y

` Another object is to improve the locking mechanisn'i employed in connection with the s\\';ingi1ig doors whereby any of the doors or vany `number of such doors may be Yquickly and readily disconnected from the mechz .nism that yis mployed for silmlltaneously unlocking the doors to allow of materialbeing dumped, sothat such door or doors will vremain closedwhi'le the remainder of the 40 doors at that side of the ear will be un- 'locked by the'operation of the generallocking mechanism referred to. l

It is a :further object of the invention to provide improved means for locking all of the doors immediately after they have been raised into Vclosed position, and in the event that the` doors are raised by the air1 )ressure devicesreferred to,to automatically move such locking mechanism by air pressure.

I accomplish these stated objects as well as improve generally 'the construction and ,dieration of dump cars of the -type mentio-ned` by the devices and Vcombinations of vdevices shown in the drawings and hereinafter specifically described.

l That which I believe-to be new -Will be i pointed out in the claims.

' In the drawings z-*Figures 1- and Q toi gether constitute a side elevation of a car embodying my improvements, a portion of illustrato some ot the operating mechanism located at the end of the car, and the other end portion of the car being omitted in Fig. 2. Figs, 3 and i together constitute a plan vie\\',--some parts being in sectiom-of so much of the complete ear as is shown in Figs. 1 andQ. Fig. is a section through the car-body at the line 5,5 of Fig. l and showing in elevation some of the door operating mechanism. Figs. G and 7 are vertical crosssections taken respectively at lines G-G of Fig. l and 7-7 'of Fig. 2. Fig. 8 is an enlarged detail, being a side elevation of the lever and pawl-and-ratchet means employed to raise by h'andthe `doors at one side of the car. Fig. 9 is a detail of one of nism for operating the same, the latch being in inoperative position. FigalO is a view of the salncpartsV shown in Fig. 9 but with the latch projected into the position it will oc- Fig. 11. is an edge view of the devices of Fig. 9, the supporting parts for such devices being in sectio1`1,-tl1e.section being taken on line 11--11 of Fig. 9.

Referring to the several figures of the drawings, in which corresponding parts are indicated by like reference characters'VfQ() indicates the side sills of the car, preferably formed ot' heavy channel' pieces, and 2l inof'ehannel pieces spaced a distance apart as shown in Fig. 5. Asl sta-ted in the said Letters Patent', No. 929,104, the centra-l sill is not. continuous from end'to end, as it does not. extend across the delivery openings in the bottom ot'. the Car.

22 indicates the body of theV car.

Thecar is divided centrally, as shown in' large compartments having sloping sides and Aends. ments are normally closed by two doors for tral line of the car, ass town, and are pret'.v erably constructedas fnl-ly described in mv said form patent. 'lo the doors at each the car-body being broken away in Fig. 1 to cupy when holding a door in closed position.

dicates the central sill, made also as shown' Figa, by partition 2.3, thus' forming two The bottoms of these comparte.

the door lat-ches and a part of the mechaj each compartment, the doors being indicated bv 9.1i. The doors are ln liged along the een#l side of the car is attached la flexible connection which as shown consists of two chain sections 25-26 and an intermediate rod section 27. One end of each chain section is attached in any Suitable manner to .one door, the other ends of the chain sections being attached to the ends of the rod sections as shown. The attachment to ,the doors is preferably through the intervention of a hinged bail, as shown, and as described in my said former patent. Instead of forming the flexible connection of two chain sections and the intermediate rod section, it is obvious ot course that a continuous, chain mightbe employed, but inasmuch asthelcentral portion does not have to pass around any pulleys, I prefer to intel-pose the rod section as being less liable to stretching or distortion than chain links.

That portion of the flexible connection formed by the chain section 25 passes up through a suitable opening in the usual long plate 28 that extends from end to end of the car at the side of the car and over a suitably-journaled pulley 29 and -then-ee over a pulley 30 at right angles to the pulley 2!) so as to direct the chain toward that end of the car Where. the operating mechanism is located. The pulley 30 is preferably covered by a suitable housing 31. The otherend of the flexible connection referred to,- namely the chain section 2G, in like manner is led over a pulley' 29 and around a pulley 30, and, as clearly shown in Fig. 3, is looped around a pulley 32 which is journalcdV in aV yoke 33 at the end of a rod 34, which, in the construction shown, is the rod of a piston movable in a' cylinder 3G. Atthe opposite side of this piston 35 is connected another rod 37 which has attached at its opposite end a chain 38 adapt-ed to be wound upon a drum 39 .extending transversely of the car. This drum is.l mounted upon a shaft 40 suitably supported in bearings.v The shaft 40 in the 'construction shown is locked end to end to another shaft 41 bymeans of a suitable socketed casting 42. The

shafts 40'and-4l therefore in eit'ect are a single shaft and might if desired benardey of'a single piece, although 1 find it a praetical advantage `to make it in two parts as described. Around the shaft member 41. is a Strong coiled' spring 43 having one end secured to the coupling connection 42 and its.

other end secured to a fixed part ot the car frame. The tendency of this spring is to kcep'the chain 3S coiled ori the drum 39. The inner end of the shaft section 4l is adi' jacent to the longitudinal center of the ea r,

as clearly shown in Fig. 3, and it has fixed] ysecured to it near that` end a ratchetwheel 44.

45 'indicates a lever, loosely journaled upon the shaft 41, the lever in the ctms-truetion shown being bifurcatcd so as to straddle.

the ratchet wheel 44. As shown,'this lever is not made of a single piece but the handle port-ien lies between the two members that straddle the ratchet-wheel 44 and is riveted to such.p:1rts, suitable filler blocks being interposed between the handle portion and the bifurcated end nien'ibers, as clearly shownin Fig. 3. bifureated lever ot' course could be used. Between the forked endsl ot` this lever 45 and a short dist-ance from the ratcl'i'et-wheel 44 is journaled at 47 a pawl Fig. 8) 46, adapted to engage the teeth ot the ratchet-- wheel 44 and turn such ratchet-wheel when the lever is raised, the pawl of course sliding over the rat'cl'iet-teeth when the lever is being depressed. lImmediately below the pawl 46 when the lever is depressed, is pivvotally secured a locking dog 48, the pivot of the same being indicated by 49. This pivot 49 is supported in a fixed bracket 50. The dog 48 at the opposite side of the pivot is provided with a short upwardly-projecting arm 5l which is adapted to he contacted by the lower edge of the lever 45. \Vhen the lever 45 is raised, as is indicated in Fig. 8 in dotted lines, so as to remove it from contact with the arm 51, the dog 4S will fall into position against the ratchet-wheel 44 to lock the same against backward rotation, the pawl 4G at the Same. time falling into position' to vcause a rotation of the ratchet-wheel as the lever continues to be turned upward. When thc lever is moved downward sufficiently far to come in. con-- tact with' the arm 51, the dog 48 will be forced. out of locking engagement with the ratchet-wl1eel 44, and, as it rises, will turn` the pawl 4G also out'of engagement with the 1'atehet'.wheel, leaving the vratchet-wheel An ordinary one-piece free to rotate backward to permit the doors ]"iower, the hand power being applied through a hand wheel 52 lixed on. the end of a shat't 53 journaled in suitablesupports, as clearly shown in Fig. 1. '.I`o this shaft 5:5 is securedone end of a chain 54, the other. end ot which chain is equipped. with a hook 5:3 that isv adapted to be readily .inserted in and withdrawn from ahole. 5G in the lever 45 near the tree end thereof.

'lo-sulli'ciently windthe chain. 38 upon the drum 39 so as to insure the complete closing of the '(loolis, the lever 45 must be moved up and down several times, according to. the/construction illustrated, .and it is therefore important that the chain, when fully let out from the shaft'fi', be not long enough to perl-nit the lever'i to be swung 1 down sufficiently to contactwith vthe arm 51 of the dog 48, be( '.ause,'if thatl happened, the said dog would be released from lot-king engagement 'with the ratchet-wheel as before ldescribed and Aallow the"partially raised i 'i doors to fallU It will be understood that by thus reciprocating lthe lever through thel operation ot' the hand wheel 52, the eliain 38 will be. wound up on the drum 39, drawing toward the drum the rods 37 and. 34, as well as the piston interposed between them and drawing also the flexible connect-ion consisting of the ehaiiisections 25-26 and the interposed rod section 2T. These chain sections 25 and 2G, connected as they are to the front ends of the two swinging doors, necossai-ily pull those doors toward a closed posi tion, and, assuming that the doors are of the saine weight, that the chain sections are of the same length, and that each door inov'es toward closing position with the saine amount of frictioiial resistance, both doors will` be brought into raised position'practically at the saine time. It, however, these Conditions with reference to each door are not equal for any causev` 'one door will lbe brought to a 'closed position ahead ot the other, but, by the construction provided wherein one chain section is looped around a pulley that travelsI lengthwise ot the car, the door that lags behind in its closing,-

wliether due to its chain section hating; be-

come unduly elongated from use, oi' because.

of unduefrictional or other resistaneef nuist be brought'to an absolutely tight clos ing position the saine as the otheigdooibecause the pulley 32 will rotate sutliciently during its bodily movement toward the end of the car to permit of a drawing up vof the chain section attached to the slowein-iiiovinerv door so as to insure suoli slower-nioving4 door coniingtt.) place, and thistoo without. in any wise releasing the upward pull necesto hold the other door in position.

itdoes away with the 'necessity of niaintaining the lifting: chains always of exactly the same length.

45 t `The mechanism-sd tar described is duplicated atteaeli-Side'fof th'e car', and it is neees-v sary 'When/raising ,these doors by hand )ustdescribed-to'.separately operate the two sets offinechanisiii for raising the doors at fthe twolsides., I ,contemplate however, the

,Y of the doors when desired by power, and to that end I have rovided air mecha aisin nism which I will Vnow escribe. l

jindicates a reservoir suitably secured @inA place on the oar and supplied with air ,from-.the usual train pipe 58 through a triple valve' 59,-the connectioii being the saine as in the use of the ordinary air-brakes.' A reductiontof air in' the train plpe 58 causes ,air to flowthrough the pipe 60 into the cyl- Vinder- 36, forcing the .piston therein back until ,a port near the inner end of such pisy ton-fisuncouered allowing the air to escape therethrough into ,av crosspipe 61 from Awheneeiitv-is conducted into another cylinder 36 atthe opposite side ofthe eary and f o'rcv ing back therein the piston iii that cylinder. When that piston has been forced back to the liinit ot' its stroke, all i'our doors ot' the car will have been tightly closed by the suceessive pulls exerted on the tivo ilexibleoonnections already described. When the piston that last acts to vlose the doors on its side of the car has about reached `the limit. ot' its inward stroke, it uiirovers 'a port that permits the air tto rush into va pipe ('2, troni which it is conducted to one et a pair ot cylinders suitably mounted near the end of the ear and whose function will be hereinattei.' described, lour-iiay valve ($3 permits the reservoir 57 to be cut out and the apliaiatus used as in straight air brakes.

I provide lot-king mechanism tor securing; the doors in their closed position, the saine being' ot" substantiallyl the saine character as that described in my said toi-nier lateiit,N i. 920,104, but ditl'eriiig ironi what is described in that patent in that provision is iliade for permanently securing the lot-king` mecha- -iiisiii of any one or more oi. said doors troni being' alt'eotcd by the turning oit the. rook sha'lt. The looking mechanism referred to is descril ed as follows'z-( indicates a shaft, preferably angular in cross-section, as shown, except at its bearingportions, one of such shafts beingprovided for each doei' and beingl of a length substantially thesanie as the length ot` the dooi'. lllach of these shafts is suitably journaled near its ends in a pair ot braekets ($4 formed of short sections of channel-iron that are secured near the innerl tane ot' one ot the side sills 2th The portion of the shaft tit-l4 between the channel.- iroii pieee-s (34 is squared or angular, as indilcated inliig. 1l, and to thissquaifcd portion is secured one end ot' alink (l5 between the forked upper end of which l'iivotally attachcd another lilik (Sti, which at its other end is pivotally attached toan irregularshaped block (37 that constitutes the holdingfl a short link (59', tothe other end ofwhich is pivotall y atta ehed an arni 70, to the upper end of which ai'fin is pivotally attached a link Tl that is iii .turn c'oiiiieoted xedly to along `rook`shaft 72, tlie rock-shaft being scribed. in my said former patent, and' pro-` jeeting toward V tliatgend of the oarwher'e is located the door-operating mechanism thatV suitably supported, as `for exampleas de? rnisms for both set of a removable f secure the arms s arm 70 and link 71 disconnected as suggested crank lcveraud said crank.

has been described. 'The' turning of lthis rock-shaft 72 throws the latches 67 that are controlled by itrinto and out of operative position, as is fully explained in my said patent. .It is understood that thev latching devices are duplicated for each side of the car.

lIn my said fo'rn'ier patent, when a rockshaft 72 was operated, the latching mechay door at'one side of the car \ve1e simultaneously operated and had to be simultaneously operated. In my lpresent construction, the latching` mechanisms for both doors can be operated together, or, if desired, one in place so as to be unaffected by the turnlng of the rock-shaft 72, but such permanent locking,lr of the one door will not affect the latching or unlatehing of the-other door. I accomplish this objectby making the pivot 73 that unites the pin and by providing a fixed bracket 74.- at one side of the arm" 70 through a hole in Which can be passed a pin or other locking device and thereby firmly7 to said bracket. WVith the and the arm 70 locked in this manne-r to the bracket 74, it is evident that the turning of the rock-shaft' 72 can have no effect upon the latch connected with the arm 70, and it is door can be permanently lockedv arm "70 and link 71 of each aiso evident-'that when said arm 70 is locked tothe bracket 74 the latch 67 connected -With said arm 70 cannot be' disturbed and therefore the door. will be, for the time heilig,l firmly lockedtin place.

At the end of each rock-shaft 72 is fixcdly secured a. short crank --arm 75, and also on the said rot-.k shaft auf] lying' next to the said crank armis a bell .crank lever 76, which, however, is not fixediy' secured to the said shaft so as to rotate therewith but is free to rock indcpeiulently thereof. This bell crank lever isprtfvided, as shown, (see lflig. 5)

I ith a hole 77 throughn-'hich apin is adapted 'to be passed an'd also' through a corresponding hole in the crank arm 75, thus for the time heing'loc-king together said bell Y To eachv bell crank t is pivotally,attached one end of a f lung connecting rodffS.

At its upper end, this lever is suitably connected to a chain S2, the ends ofwhich are secured to '.aud adapted to Wind upon the shafts of two hand Wheels Stk- 83 located at ,the end of the l .a|j`and near opposite Sides thereof.

The two bell cranks 76 are similar, .but are differently positioned upon their respective rock-shafts 72, whereby, upon the turning of the lever79, they will be caused to simulta-neously turn their respective rock-shafts,

'will proceed to describe how lthe v79, and hence .as the assuming that they are secured to their ifsspective"tranks. 75 as"described, s0 that the latching mechanism at; each .side of the car will be simultaneously operated and in the same manner. sired to unlatclrthe doors at one side of the car only so as to dump onlyat that side, the bell crank lever at that side of thecar will It is evident that if it is dehe locked to its adjacent crank 75, While the one side of the carbe left locked While the` others are being opencd,.but that by locking both bell. cranks to their respective cranl" 75 all of the doors-can be rsimultaneously opened, or, by the proper disconnection from the latching' mechanisml of certain of the a rms 70 and locking them to t-heirrespective brackets 74, any one or more of the doors on .either or both sides of the car may be disconnected and removed from the eii'ect of the general unlatchmal mechanism.

.Having now described the manner ofA operating the latching mechanism -by hand, I 1' same operation is performed by the power mechanism provided.

I have hereinbefore called attention to the factthat the air, after having moved both pistons in the respective -cylinders 36, escapes throug'h a pipe 62. passes into the rear end of one cfa pair of cylinders arranged at the end of the c ar, the cylinder into which it passes being ivrcatml by 84. This cylinder is provided with ne usual piston whose piston rod 85 is suita ly connected with the'vertically-disposed lever piston is pushed out that lever 79 Will be-'swungon its pivot 80, turning the respective cranks 76 through the cross rod 78, and, tl'nough'the consequent .movement of the rock-shafts 72, causing a latchin'g of the doors, as before described. The other cylinder referred "to is indicated by SG'and is provided 'also'of course with a v piston, the rod for which is the same 'rod 85v that is connected to the piston in thecy1in der 84.
