GRAIN-DOOR.

Patented Oct, 21,- 1919.

Application filed December 22, 1917. seria ivo. 208,442.

To all whom it may concern:

Be it known that I, BEvILL N. Van'- I woR'rH, a citizen of the United States of grain doors, particularly those employed on a railway. box-car, and the objectof -my improvement is to furnish a doorwhlch will be movable longitudinally along the outer face of a car, and which will be movable to shift into or out of a door-casing to a position for such longitudinal movements,

without obstructing the door-opening and without in any way modifying the interior walls of the car; Other improvements. will be more specifically described, pointed out in the "appended claims, and shown in the drawings, in which Figure 1 is an-elevation of a portion of the outside of one side of a box-car equipped with lay-improved grain door, the latter being shown in its closed pos1t-1on;.F-1g. 21s a -fragmental view, in

- plan, of this partof the car and closed door as shown in said Fig. l, but with parts removed; Fig. 3 is an enlarged fragmentary view of said door and the movable closurefor the crevice between one side edge of the door and the casing jamb; Fig. at is a like view to that given in said Fig. l, but showing the door shifted away from the-doorcasing opening; Fig. 5, like Fig. 2 1s a frag- 'mental plan view of the parts shown in Fig.

at, with parts removed or sectioned away; Fig. 6 is a rear elevation of the door and its casing; 'Fig. 7 is an enlarged detail plan View of the movably-connected fixed and movable rails and the mechanism for releasably holding the movabl rail: Fig. 8- is an elevation of parts shown in said Fig. 7, with the lower anti-friction bearing and guide rail, and showingthe door after its opening movement has commenced;-Fig. 9 is a plan view similar to Fig. 7, but showing the moving'parts in an intermediate position, and Fig. 10 is a like view, showing these parts in their final positions; Fig. 11 is an elevation of the parts shown in Fig. 10, showing theca'm completely rotated; Fig. 12 is a transverse vertical section taken on the broken line 12-12 of Fig. 10,'and looking in the direction indicated by the arrow.

In the drawings, similar numerals of reference denote corresponding parts throughout the several views.

The numeral 1 denotes a railway box-car having a door-casing 2, whose opening may be closed by a door at, the latter being movably supported sis-follows. a I

On the outside of the door-casing, over its opening, is supported a track-rail 22, preferabl'y a Z-bar in cross-section, while on the outside of th car, at the same height, is bracketed a spaced fixed track-rail 23, the

' rail 22 being bodily translatable to or from the car, so that one of its ends may be i brought to abut uponf an end of the fixed rail toplace the two rails in longitudinal ahnement. A fixed bracket 28 on the car, as shown-in Fig. 5, has a longitudinalslot 29 to receive a bolt 30 which also passes through an end of the rail 22, the bolt being slidable in said slot, when the rail 22 is shifted outwardly away from the car 1. Another bracket i-l is fixed on said car at the opposite side of the door-casing :2. and has a horizontal part 45 provided with a longitudinal slot 50 through which extends a depending T-head lug 51, shown in Fig. 8, to disconnectibly and nlovably connect the other end of the rail '22, here denuded of part of its lower flange, to said bracket. The adjacent end'of the fixed rail 23 is secured to the outer extremity of the l) acket ll, and has its enddenuded of part of its web and upper vertical flange over said slot. Another bracket 32 supports the other end of the rail 23.

The door i has its edges preferably seated andextendcd into rabbeted grooves 3 in the adjacent parts of the door-casing. to serve as stops and closing-1neans.- Thedoor has a pair of erect hooked bars 2-l secured to its upper part on spacing block to serve as hangers, in each of which are alined'orifices to receive the pintles of rollers which -roll along the upper flat parts of the rails 22 and 23! -As shown in said Fi when I the door is seated or closed within the doorcasing '2, the rail 22 is shifted'bodi'ly inwardlytoward' and'nearly in contact with the outer-face of the ca l, being thus con- ,siderably'ofiset fromand out of alinement with the fixed rail 23.

nally along said rails.

Referringnow to said Figs. 7 to 11 inclusive, the numeral 32 denotes a bracketedshelf fixed on the side of the car 1, said shelf having the longitudinal edge of cam form, and having a roller 52 rotatably imounted on "a stud thereon to extend slightly beyond ts edge. This shelf underlies the horizontal slotted bracket 45, spaced therefrom, and is cut away at the rear sufficiently to seat it above the depending v bracket part 44 as, also over the depending part of a smaller bracket 46, the horizontal.

part of the latter resting across the shelf 32,-

an'diboth orificedin line with the orifice in thefloverhanging bracket part as, said 'a-l'ined OIlfKZGS receiving a short rock-shaft 4-2 on whose upper end above the bracket 4:5 is.

fixedly mounted a cam 38 having a reentrant recess ll intermediate between a curved part '33" and aflattened part 48, the latter being undercut, as shown in F ig. 11 Between the brackets and 3-2 and overlyin the bracket part 47 of the bracket 46, a bifiircated arm 4.8 isfixed on the rock-shaft 4:2 to extend horizontally; therefrom and has a roller 49 rotatably mounted between its forks.

ea go -"-of the I elinevl bearing for the door When the (100114: is seated in the rabbets 3 of; the casing'2 ,the extended part-54 of the movable rail 22 extends slightly behind the flattened part &3 of said camj VVl1'en the door. is and the rail 22 are moved together outwardly, the end 545 of the rail rocksthe cam, its'shaft 4'2and' the arm 48, having entered the recess 41 of the cam 33. When the door'4 is shifted'longitudipally to the right on the now alined rails 22-23, it contacts with and rides upon the "roller 49 in ,said arm 48, thus holding the cam 33 fast against the movable ra-il'22 atits end part 5-1 tojlock the rails 22-23 in alinemen-t. The rails are thus retained in fixed alinement until the door is shifted back to the left to release said rollerji9.

In the operation of translating the door and movable'railoutwardly, as above described, the roller 52 bears agamst the inner facehof the'door while being moved to the anti-friction bearing, the cam ri'rht, as an I I I I shelf 32 also acting as an 1nitS; further progress to the right. A like bracketed shelf 56 fixed on the car below the shelf 3'2 carries a rotatable. roller 57, asshown' in- Fig. 8, which'likewise acts as an anti-fric-. tion bearing for the lower part of said door while the latter -'is being translated to the the door engages these sloping arms and is pushed inwardly to its seat in the door-casing. While this is being effected, the extended part 54 of the rail rocks the cam 33 its edge passing into the recess 4:1, and the arm 48 rocking to its first posit-ion. I have shown in said Figs. 1 and 3, fasteningmeans and crevice-closures for said door when the door is seated in the door-casing rabbets 3.

The numeral 39 denotes a flat bar-,or which may be an angle-bar, positioned vertically alongside the T-iron side-plate 9 of said door and hung on hinges 37 having extensions or hasps 38. On said door in line with said hasps are plates 34 having paired lugs 35 to receive the hasps between them, the -lugs being orificed to receive split-keys 36 to fasten the hasps releasably to the lugs, when the bars or angles 39 are swung over to cover the-crevices between vthe door-casings and theT-iron 9, and also overlie the plates 9 to secure the door inplace in its seat. lhe T-irons 9 .seal the ra'bbetcrevice 40 between the door edge and the jamb-Q.

The crevices are thus sealed, and exit of small grain avoided. v Certain of these closures 39 may be dispensed with when desired, as indicated in Figs. 4 and 5, and other fastening, means employed without departing from the principle of my invention,

A swinging door or grain-outlet 6 is provided in the lower part of the doors, hinged thereto and operated by means of lever-arms 7 on double-joint hinges, to simultaneously lift and swing outwardly 'saiddoor, but this feature is not claimed herein, being specifically claimed in a pendingapplication for patent.

It will be observeld that in my improved device, the grain door-is suspended outside of the car, is translatable longitudinally therealong, and that there are noparts extending into the interior of the car to 0b- ;stri'lct loading thereof. 4

first position, theleft-hand vertical edge of It is to understood that this invention is intended to'include all mechanical equivalents of its parts, and that various changes can be effected without departing from its principles. I

Having described my invention, what I 1 claim as new, and desire to secure by Letters the fixed rail when the door is being shifted from one to the other.
