A sliding door 12 is hung on a track 13 invention may be and is movable over the outer surface of the side of the car on said track to open and close theopening 11, said door 12 being suspended on said track by rollers 14 and being held against the side of. the car during movement by a series'of guide brackets 15 15, This is purely a conventionalarrangement and is practically all box car .construction. I r

Referring noW to the application of the invention to the box car illustrated, fol

lowing the usual practice where the car is employed for transportin wheat, rye, oats and'other commodities in iulk, there is provided a so-called grain door 16, composed of the -planks 1717 vertical cleats 18-18 and diagonal brace 19, the cleats and brace serving to connect the planks, saidcleats being arranged a short the planks 17,. This door 16 is placed inside the car, one edge 20 of the door overlapping the door post 21, an angle-iron'22 or cleat being provided upon and secured to said post for abutting theiedge of the door, and the of said door lying adjacent the other post 23 and in abutting relation with a displace'able angle-iron 24, secured to 23 as will be explained presently. It will be seen from Figure 3 that the grain door,

that there is no interference with the operation of' thesliding door 12. The angleiron 22 serves toprevent endwise or longithe grain door in one the car is in transit or being door site direction. f

The displaceable angle-iron is suspend ed for pivotaland slidable movement from a lag screw or bolt 25,

F or retalnlng the angle-1ron 24 or lock-bar against movement, as shown in Figures 1 to 3, inclusive, there is provided a second lag screw or bolt 28, driven into one face of the door post 23 near the floor of the car, and the adjacent flange of the lock-bar 24 is provided with a slot 29, preferably right-angular in shape and opening at the inner edge of the lock-bar, the slot 29 being flared at its open end for facilitating slightly engagement with the bolt 28 The slot 26 permits the engagement of the bolt 28 With the slot provided therefor, this beingaccomplished by raising thelock-bar until the bolt 28 enters the slot-29, and then permit-" ting the lock-bar to drop. of the lock-bar 24when in sition abuts the door plate the lowered 'po- 30 and a recess 30 is provided in one flange of the an lebar to permit of the insertion of a crowar 31 (Figure 4) for raising the lock-bar when it is desired to release the door while subject to pressure of the contents of the car.

The purpose of the angle-iron 24 engaging the door plate 30 is toprevent the escape of the material held between the edge of the door 16 and the post 23. Additional lag screws and slots therefor may be provided in the lock-bar'where the opening be subject to flexing. However, this might as freadily'be taken care of by employing a heavier angle-iron.

As will be seen in Figure2, the lockbar 24 is adapted to be swung up into the car when not'in use, and will thus be out ofthe way,'it being evident from Figure 2'that the distance between the. upper end of the bar and the top plate 31 of the door opening is suflicient to permit such swinging, and the slot 26 is of such length that the upper end of the lock-bar cannot slide outwardly into the path of the sliding door 12.

ment when seating same in the stirrup. From'theforegoing it will be seen that the inner or temporary door 16 is rigidly re tained in position against the pressure of the contentsof the car, and that the removal oi the door, even though under great pressure, may be quickly and facilely accomplished by'the use of the crow-bar as previously mentioned; This'means a great saving in time while the cars are atfthe pits where and'thereby re duces the time required for unloading and 1 consequently releases the car from the siding; 2o

, With reference to Figures and 8, there is provided a modification wherein the door post is shown at 38', this post being of the standard wooden construction; In this arrangement'the door post is provided on the face38' with a fulcrum plate 39, near the top of the side opening, said plate being securedto the post by screws 40, or the like,

i and said plate having a vertical substan tially central slot 41; In this instance the takes the same form as the bar 24 but said bar 24' is provided with a fixed bearing stud 42, said stud lying within; the slot '41. A lock plate 43 is secured by screws 44 tothe face 38 of the post 38, relatively close to the floor of the car, said plate having a slot 45 therein 46 into which the lock-stud 47 stud also being fixed on the angle-bar 24'. The studs 42 and 47 tical, the latter only being fully shown, comprising a shank reduced at 48 to enter andriveted at 49; The each have a nut 50 thereon, there being provided sufficient play to permit the lock-bar to be swung into the car when not in use. The post 38 is pro vided with an elongated recess 51 for accommodating the stud 47, and a recess, not shown, is also provided for the stud 42. This form of the invention eliminates all projections from the door post into the open I-Iowever, both forms so far merchandise.

vReferring now to Figures 9 and .10, an

application of this invention to a steel door post 52 is there shown. There are a number of different styles of teel door posts, but that shown will serve to convey the idea here. In this instance, the lock-bar 53 is pivotally and slidably mounted uponf 31c 0 1e rovided witha notch. drops, said are substantially idenand such as might interfere'with loading,

door post, a slot 55 in one lock-bar serving to engage door post is slottedv shown in Figure 10, said stud havingareduced shank 58 riveted at 59 in the door post, the enlarged portion ofthe studentering the slot-55 and being provided with In some instances the door post jo'li' nietal is hollow, that is, there is-no wooden post within the steel casing, and in this event the stud 57 may be modified as shown iii-Figure 11.= Here-the stud, designated-57 is loosely mounted in the steel casing 61, and said casing isprovided with a" countersunkopening for receiving the head of thestud when not inuse, the stud being withdrawn until the nut 62thereon abuts the casing, whereupon the lock-bar, in this instance similar in con struction to that shown inFigureil, may be engaged therewith It will be readily seen.

tha the several forms of this invention shown readily adapt the device to use on the various typesof box freight doors. g 7

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is 1. In combination, a container for material in bulk, said container having'a side opening 1 and aside post, a closure within said container for said opening, a bar on one sideof said opening,

and means fixedly mounted on the post and with which said baris slidably engageable for holdingsaid bar for retaining said closure only against pressure fromwithin the container. l

2. In a device of the character described,

in combination, a vertical post forming one side of an opening, a floor, a closure "for said opening, a flanged element pivotally and slidably mounted on a fulcrum on said post immediately adj acent'to the top of the opening, means on the post for locking said flanged element in with by movement of the flanged element in two planes, flanged element being recessed to afford a space wherein a tool'may be inserted in contact with said flanged element and the floor for disengaging said eleme'nt'from said.
