I Application filed May 3,1928. Serial No. 166,156.

My present invention has reference to grain or similar cars, and my primary object is a particular construction andmounts for inside doors of such cars, whereby the doors may be readily moved to. an out of the way position in aear and secured there when the car is empty, and readily returned and efiectively locked to the door openings when the car is to be filled.

A further object is to provide a box or grain car with inside tracks ofrpa rticular and peculiar formation, the rails of each track being engaged by rollers on the posts or hanger members for the doors, so that the doors, after they are unlocked, may be raised on their hangers and moved bodily therewith to the other end of the rails which terminate at the center of the ends of the car, at which points the doors may belowered and secured to the said car ends, so

that the doors will be sustained in an unobstructing position when the car is empty, and further wherein, when the doors are in normal car closing position they will be effectively, locked on the car to establish a grain tight closure therefor.

A further ob'ect is the provision of a device for this purpose which may be readily installed in different classes of box cars, and

which, while of an extremely simple construction, will be found thoroughly effective for its purposes.

lVith the abovebroadly statedobjects in view, the improvement further resides in certain other novel features of construction,

' combination and operative association of parts, my preferred embodiment of which is illustrated by the accompanyingthree sheets of drawings in which:

Figure 1 is a central vertical and longitudinal sectional view through a sufficient portion of a box or grain car to illustrate the application of my improvement;

Figure 2 is a horizontal sectional view approximately on the line 2-2 of Figure 1; Figure Bis a transverse sectional view showing the door latched against one'end ofthe car;

Figure 4 is a fragmentary side elevation, as seen from the outside; and i r "Figure 5 is a detail elevation of the upper 7 portion of one of the hangers, the rail being in section.

distinction by thenumeral 3, and each of these posts is bored to provide spaced sockets V 4-; for the reception of bolts that are slidably, mounted through brackets 6 that are fixed on theouter side of the doors 7.

,On each bracket plat-e6 there is pivotally secured a cam member 8 designed to engage with thehandle portion 9 ofeach bolt when the bolts are thrown home. f

Each door 7 has on its ends facing out wardly the vertically, extending cleats 10% the outer edges of which engage the inner edges 'of the sides of the door opening 2 to make a grain tight joint, and on the' outer face of each door thereis securedan elongatedmetallic supporting member 11 having the flanged ends 12. The brackets 6iare secured on thecleats 10 and on extensions 10 thereof, which might be separate bloc-ks;

A rod l3'extends through suitable openings in the flangeslgof the members 11, and for conveniencel will hereinafter refer to the said rods 13 as hangers for the doors 7 The lower end of eachThanger may be j Fixedlysecured by any suitable means to, or adjacent to, the top ofthecar 1 there are oppositely directed rails 18(1Each' rail preferably has the cross-section of an ,I-beam;

that is, each side. ofr'the' rail is grooved.

throughout itslength. "Each Trail includes a straight portion 19 arranged substantially parallel with and (close to the respective sidesjof the car. 1 From the straight portions 19 'tlierails are curved, preferably in an ogee curve, as at 20, and from thence are extended in a straight portion, as at 21, tothe respecrails, terminate ina plane with a vertical [T'By reference to FigureQ of the drawings it will be noted, that the respeetive} ends' o'f 'tive ends of the car. Thefportions 21 of the I the rails 18 have depressions therein, as at 22 and 23). The depressed portions 22 are disposed in a line with a vertical center of the door openings 2, and of course, the depressed portions 23 are disposed at the ends of the ear. The rollers 17 are designed tor. travel on the lower flanges of the rails 18' and are out of contact with the webs of the said rails.

lVhen the doors 7 close the doorways 2 the rollers on the hangers 13 will be received in the depressions 22, which allow the said doors to rest on the floor of the car, on each hanger 13 there is secured a flexible element which is preferably in the nature of a chain 24, while on the upper edge of each door 7 a hook 25 is pivoted. When the bolts 5 are thrown to' unlocking position the door 7 is-raised on its hanger and is held out of car floor contacting engagement by bringing the hook25 into one of the links of the chain 241 The door may be now bodily moved with the hanger on the track 18, and after travelingoverthe curved portion 20 of the said track, the door is swung on its hanger to bring the said door transversely of the car. The door is further moved on the track until the said door contacts the end of the car. The hanger with the door rollers will move downwardly as the rollers are received in the depressions 23, and the ends of the car have pivotally mounted thereon angular latch members 26 which are swung to engage with and .hold the door from movement. hen the doors are thus positioned no obstruetion is offered to the loading or the emptying of the car if used for other materials not requiring the use of grain doors. lVlienthe doors are brought to elose the openings 2 a perfect grain tight joint between the doors and the car is eiTectiv ely provided, and incident to the latching of the doors in either their opener closed positions accidental movement ofthe said doors is positively, prevented. a

While I have shown and described my invention as embodied in the form which I at present consider best adapted to carryout its purpose; it will be understood that it capable of modifications andthat I do not. desire to be limited in the int srprctation ot the following claims except as here necessitated by the. state of the prior art. l V hat I claim as my invention a ud'desire to securehy Letters Patent is lf'l he con'ibination of a grain car or the like having door openings inthe sides thereof. inside doors for closing said openings. and means for locking the doors in cloed position, ofa double-flangedover head track having a portion disposed over each door and from thence curved toward and terminating at the centerof the ends, ahaii'ge hay ng a b furcated upper end, rollers' ournaled therein and disposed on flanges of the tracks, means swingably connecting each hanger to each door, and means for holding the doors raised on the hangers.
