,Toallwhom it 'may concern: flanges of the side-members of the doorit known that I, ABNEii J. DENToN, a frame .1. Thus when the car isflled with citizen of the United States, and a resident lgrain, the outward pressure thereof u 'onthe of `Nebraska City, in the county of Ot'oe and oor is received on said rollers 7 and t e door G0. State of Nebraska, have invented certain maytbe raised with comparative ease, the en- -'new and useful Improvements in Grain-'Car` gagement between the'door-'frame and the lDoors, ofwliich the following is a specfi'eaplates 9 causingwthe latter to move up `with tion. 1 j the door, while the rollers 7 roll up between My invention relates to doors for grainsaid plates and the backs ofthe guide-bars, 65 cars and it is theobject thereof to provide a as indicated by the dotted lines in. Fig. '5. door of this class ofxsimple, inexpensive'and The plates 9; in addition to providing an en` durable construction, and .having means for lar ed bearing surface for the rollers, prevent raising the vsame to-provide a relief openin lea aoe of grain around the'llanges of the thereunder, means for elevating the door an door-frame through the U-sliaped guide and 10 l sus nding the same near the roof of the car, between. the' rollers.
an means for vreducing the friction'between For raising lthe door, a' hoisting mechanthe door and door-frame to` facilitate the -ismisprovided,asfollows: To the roof-beams raising thereof when under pressure of the 10-of the car, near the conter thereof and exgrain inthe car; tendin longitudinally of the 'car, a shaft 11 75 dying my invention 4is revo ubly mounted as shown in Figs. 1, 2 1s illustrated in the accompanying drawings and 7. On one end of said sliaftis secured a v -in which j j notched wheel 1Q, and adjoining said Figurel is a transversesection of a car notched Wheel isvinounteda ratchet-lever-13 having my doors applied thereto, Fig. 2 is an carryinga manually-releasable dog adapted 8o 425 inside elevationshowing one of the doors in 'to engage the not-chedfwheel so that the closed osition, Fig. 3 is a detail plan section shaft may be turned thereby. pawl 14 throng one side ofthe door and the' anti is mounted on one ofthe roof-beams 10 near friction guide therefor, Fig. 4 is a detail elethe notched wheel, said pawl being weighted v vation of the face of said'guide, Fig.` 5 is a'. to hold the samenormallyin engagement 85 30l sectional elevation of the same, Fig. 6 is al dewith the wheel. The `pawl may be raised ofthe hoistingehaas.
tail sect-ioiiofv the upper side of ,the door, out of engagement witlil he wheel by pulling showin onefof the sus ension hooks tliere-l downwardly on the cord 15, a stoppin. 16 for, an Fig.. 7'isadeta' end elevationof one being provided to limit the upward movevnient of the pawl. To the shaft 11, at 90 'In carryin ont my inventionl rovide a points in aline'ment with-the edgesof the vone-section ooi' whichis preferab Iy formed door, are connected chains 17- which extend by frame l-of angle-iron, or similar rolledfrom the shaft over ythe pulleys 18 andy "steel'structural shapes,with 'a coveriniY 2 of thence downwardly, being connected with` `slieet-n'ietal placed over said frame.' o the the' sides ofthe door, as shown. v The pulleys 05 4 0- inside ofthe door, at the positions shown in 18 are' supported by hooks 19, disposed near Fig. .2, aresecured the lu -bars 3 which are the roof of the car, and, vwhennecessary in adapted to be engagedbyiooks 4 as shown, the operation of the. door, may be released toholdthedoorin u right position against .from said' hooks. On the. shaft 11 near the E the guides therefor, efore the car is villed ends of the chains 17 are4 secured the ,drums 100 y-With grain.. The outwardly extending flangesv 20, the ends of which are conifornn tapering o f the sidefmembers of the door-frame 1 extoward the chains. Near the tops of the tend lbetween the' flanges of the U-shaped door posts 6- are hooks 2 1 whichare adapted guideba'r's 5 which are secured to the doorto engage the outwardl extending flange of posts 6 at the positions shown.v Within said the Aupper ineinbei` of t e door-frame, when 105` guide-bars 5 are disposed the small. rollers 7, the saine is elevated as show n at .the rightof the same-normally resting upon and being 1, and in Fig. 6. v
spaced apart at regular intervals by transnunloading acar provided with my door,
verse lugs 8', inte ral with the guide-bars, as the lioistingshaft 11 is turned, b ineens of 'shown in Fig.j5. gRestingagainst' said rollers the ratchet-lever 13, to windthe -c ams 17 oii v 11b` 7 are the plates 9 which, in tum, are engaged 'the shaft. One o'r two turnsof the shaft raises by the ledges of ythe outwardly extending the door sufficiently to foriria relief opening raised a much greater distance by eaeh turn of the shalt than at lirst, This may he done for the reason that after the pressure ol: grain on. thel door has been released the saine may be very easily raised and, therefore, the
- leverage of the hoisting' apparatus may be reduced to accelerate the operation. Alter the door has been raised vertically lar enough to enable it to be engaged by the suspension hooks 21, the eliains are slaekened slightly and the pulleys i8 are disengaged i'roin the -hooks 19. The Achains are then drawn taut, as represented at the right ol Fig'. l, and by is swungl up to a position near the roof ol' the car, as represented by the dotted linesv in Fig. 1, the outer edge thereof being sin )ported by the hooks 21 and the hoisting-shalt beingsr held to its position by the engagement ol' the pawl 14: With the wheel l2. In returning; the
iO'door to its closed position, the saine is lowered by alternately releasing` the pawl, turning the shaft by means el the ratchetdwer, to lower the door, and rengaging the paul to hold the shaft While the ratchet-lever is released in nialing the return nroveinent thereof. Alter the door is swung down to the Vertical position, the pulleys 18 are reengaged with the hooks 19, the door is released from the suspension hooksZl, and lowered lo to its closed position.
New, having described my invention, what lclairn and desire to secure by Letters Pat ent is: f
l. In a grain car, the combination with a door having lVertical outwardly extending! flanges at tbe sides thereof, ol guides seeured l to fthe door-posts, rollers held within said guides, and plates resting against said rollers, the flanges at the sides ol' the door being arranged to engage said plates, substantially as described.
2. ln grain ear, the eolnbiinition with a door having vertical, outwardly extending flanUes at the sides thereof, o'le guides ser-.ured to tie door posts, .rollers held within said guides, means for spacing and supporting said rollers, and plates held by eaeh oit said guides and resting" against said rollers, he flanges at the sides ol the door beingl arranged to engage said lates, and the arrangement being suoli tliat the plates inay inove up with the door when the saine is raised While under pressure oli `grain.
3. ln a grain car, a vertically slidahle door, hooks diSDosed near the rooi" ol" the ear above the door and adapted to support` the saine when engaged thrn'ewith, a hoisting-shalt I disposed near the eenter ol 'the car and exlurther turning ot the hoisting-shalt the door tending longitudinally near the roo'lV thereof', chains erninectiug said. shalt and the door, and pulleys engaged by said chains and removably held near the supportingduvolts, as and lor the purpose described.
d. ln a grain rar, a door, anli--l'rivtion deriees arranged between the door und door-- posts, ineans disposed above the door near the rar roo'l" lor suinuzrhly supportingl` the door, a hoisting-shalt und chains adapted lo raise the door verlii'nll \j, and pulleys engaged by said, chains, the said pulleys bein.;r releasable to eliuflnge the direction ol pull olt the chains upon the door, \\'hereh\ the suine alter being lilted and engaged with the sup porting means may be s uur up\\:ndl \r to a position adjoining the car roo'l".
