GRAIN-DOOR.

To all whom it may concern:

Be it known that I, EDWARD PossoN, a citigen of the United States, residing at Chicago, in the county of. Cook and State of` Illinois, have invented certain new and useful Improvements in Grain-Doors, of which the following is a specification.

The object of my invention is to provide a new and improved inner door for box cars.

A further object of my invention is to provide such a door that shall be .adapted to go across the lower part of the door openinwithout obstructing the upper part thereoV AStill another object is to provide, such a door that shall be adapted toopen andv close with facility. i

These. objects and others in connection therewith will be made apparent in the following specication and claims, taken in connection with the accompanying drawings., in which- Figure 1 is an elevation showing my improved door in closed position. Fig. 2 is a vertical section on an enlarged scale, taken on'the line 2 in Fig. 1, looking in the direction of the arrow. Fig. 3 is a horizontal section, taken on the line 3 in Fig. 2, looking in the direction of the arrow. Fig. 4 isl a hori zontal section, taken on the line 4 in Fig. 2, looking in the direction of thearrow. Fig. 5 is a horizontal section, taken on the line 5 in Fig. 1, looking in the direction of the arrow. Fig- 6 is an elevation,.'partly insection, showing part of the door bracing mechanism. hung in the top of the car. Fig'. 7 is anel'evation of the car Wall adjacent to Figs. 8 and 9 are detail sections oni the cor'- respondingly numberedlines in Fig. 7.

In, the particular embodiment of my in' vention which I havechosen to illustrate in the accompanying drawings, the door opening 15 in the side wall of a box car is boundtom by the floor 17. Avertical `rod 18 is supported, in proximity to the inside face of each side door post 16. At an`intermediate point in the height of each` rod 18 a bracket 19 engages the same, this bracketbeing se-V cured to the post 16 by meansftholt 20 and nut 2l, as shown `in F igt'r'lhrod `18 is also secure y fastened at its top and bot'd tom. The two dO'OfIIS 22' have ripper and lowensleeves 23 and124 onan edge 'of each.

is adapted to close the of each closure slide for raising them,

ends of by the bolt which-engage the rod- 18, thu's forming a'I hinge joint therewith. Thus, it is apparent that each door 22 .is adapted to swing horiz'ontally about the rod 18 as an axis, the two doors meeting in a vertical line at the center of the door openingwhen they are closed. :The'upper edge of eachdoor has a inglip 26. Each door has a folding handle 27 attached vto the outside thereof.- Above the handle a panel 28 is struck up slightly from the general surface of the door ,and below-the handle up. These' panels add somewhat to the strength of the door. Vithin the panel 29 lon the sides thereof are attached the guides 30.' Between them at the lower part of the panel 29 an opening' 31 is cut out, and a sliding closure 32 mounted in the guides 30 opening 31. Inward depressions 33` are struck in the lower edge 32 to serve as handles The angle iron34 Vextends horizontally across the door opening and has attached to its middle point by the rivets 37 the end 36 of the vertical angle iron 35, the said endv being iattened out for the purposeof af- 27 alarger panel 29 is struckv l bent over strengthening lip 25 and the lower edge of eachdoor has a similar strengthen fording greater security of attachment. At

its ends, the horizontal'angle iron 34 has one iange cutaway, as indicated by the reference numeral 38.` This leaves the other flange adapted to project out at each end behind the vertical side posts 16. Short .chainsl 41 have their ends 40l attached. to the angle. iron 34 near its ends, the remaining the said chains being attached to rings"42.which engage the rods 18. The outwardly projecting ange of the vangle iron branch 35 `carries a tongue 43 attached 44'.-- A clip 4 5 riveted toone of the, doors 22 is adapted to receive the said tongue 43. The sheet metal door sill 47 extends on the floor 17 between the side posts 16. At itscenter the Hooris cut away, as indicatedl by-the reference Anumeral 4 8: in Fig. 2. f Adownwardlyprojecting st'ud 49 is riveted to the/lower end dit theangle iron bar 35 and projects through a holein `the sill 47 directly aboveV the notch 48 Tli'eyertical meetingledges yof the doors 22 are folded over so as vto strengthen them, `these vfolds 'being opposite on the two doorsand iapping past each other, as indicated by the reference numerals'50 and 51 in EFig. 5. `Atlthe top of the door opening the two hooks 52 are secured and in these the horizontalmember 34 is adapted to rest. The ho'ok 53 is. secured by bolts 55 to the carline 54 and this is adapted to receive the extremity of the angle iron bar 35.

A vertical notch 58 is cut on the inside face of the frame members 56 and 57 (see Fig. 7). A short piece of strap iron 59 is laid'across the said notch 58, its ends being riveted or bolted' to the respective members 56 and 57. On the inside face of each door is a hook v which is adapted to engage the strap iron 59 whenl the door is opened wide.

It will be observed that the angle iron members 34 and 35 constitute a frame having a T-shape. When in the position 4shown in Fig, 1, the ends of the top-memberof this T-frame rest against the side posts 16 and the bottom end of ther T-frame engages the door sill. Thus, the T-frame supports the inner meeting edges of the doors 22 and also the top edges of. these doors, holding them securely against the pres'sure, as of a body oi grain, from within the car.'

Assuming that thedoors are closed and that the car is filled with grain, the procedure to open the doors .will be as follows: By means of the hand hold 33 in the slide 32 the latter is raised in its guides 30, as indicated at the right of Fig. 1.- The slides 32 being raised, the grain will run out through the openings 3l until there will be substantially no grain remaining to exert a pressure against the doors 22. Then from the outside of the car the T-frame 34-35,

is lifted up and the member 34 caught onthe hooks 52 at the top of the door opening, there being enough slack in the chains 41 to permit this. Next, by means of thehandle 27, one of the doors 22 is raised vertically, the hinge sleeves 23 and 24 sliding up on the vertical rods 18. After the door 22 has been raised high enough to get it above the grain which at this time will slope down to the door sill 47, then the door 22 is swung in horizontally, and the hook 60 on its inner face is caught over thestrap iron 59 on the inner face of the .car wall. Similarly, the other door 22 is raised and swung back and supported in its place against the inner face of the car wall. Finally, the depending member 35 of the T-frame 34-35 is swung inwardly and up in-a transverse vertical.

plane and its end is then caught on the hook 53 in the center of the car ceiling. Thus, the whole door opening 15 is entirely unobstrueted., The reverse operation of closing the doors will be suliiciently obvious from the descriptionA that has just been given of how they may be opened. It is to be observed that the meeting edge of the lefthand door 22,-as viewed in Fig. 1, is between the angle iron b ar 35 and the corresponding edge of the right-hand door 22` (see Fig. 5).

Thus, the engagement between the members 43 and 45 serves to hold both doors 22 tightly against the T-frame 34-35.

The little'metal blocks 61 are embedded in the Hoor adjacent to the lower edges of "the doors where they meet when closed, on the inner sides thereof (see Figs. 1 and 2). These blocks roject slightly above the surface'of the goor and 'are gently beveled toward the doors when the latter are open, but are steeply beveled toward the doors when closed. It is apparent that they will therefore act as catches to hold the lower edges of the doors 'tightly closed.

In combination, a wall with a door opening therein,I doors hinged at the sides so that they may slide vertically on their. hinges, and a rigid T-shaped brace to hold the doors, the bottom member thereof engaging the door sill and the ends of the top member engaging the side posts of the door opening.
