To all whom it may concern.-

Be it known that I, JOHN HENRY, citizen of the United States, residing at Grand Forks, in the county of Grand Forks and State of North Dakota, have invented new and useful Improvements in Grain-Doors for Cars, of which the following is a specification.

My present invention pertains to grain doors for cars; and it consists in the simple, practical and advantageous gra n door hereinafter described and claimed.

In the drawings, accompanying and forming part of this specification: Figure 1 is an elevation taken from a point within a car and showing my improvement in position to close the lower portion of the door opening. Fig. 2 is a horizontal section taken in the plane indicated by line 2-2 of Fig. 1, looking downward. Fig. 3 is a detail section taken in the plane indicated by line 3-3 of Fig. 1, and showing the upright bar of the fastening means and the portions of the doors adjacent thereto. Fig. 4; is a detail vertical section taken in the plane indicated by the line 1-4 of Fig. 1, looking toward the right. Fig. 5 is a view similar to Fig. 1 but showing all of the parts positioned to afford a clear door opening. Fig. 6 is a detail vertical section, taken in the plane indicated by line 66 of Fig. 5, looking toward the right, and showing the swinging bar by full lines in its lower position, and by dotted lines in its upper position. Fig. 7 is a detail perspective of the upper end of the upright bar comprised in the fastening means. Fig. 8 is a horizontal section taken in the same plane -as Fig. 2 and illustrating a modification hereinafter specifically referred to.

Similar letters of reference designate corresponding parts in Figs. 1 to 7 The bar A. above the door opening B is provided in its inner side with a recess a,

and the upper portions of the door post-s C are rabbeted, as indicated by 7).

Pivoted to the posts C at points 0 in the rabbets b are the arms d of the horizontal, vertically-swinging bar D comprised in the means for fastening-4. 0., supporting and preventing outward movement of the doors, hereinafter described. On its forward side the bar D is provided with a projection c, and to the rear side of said bar is loosely connected a pendent handle f. Thus when the bar D is swung up into the position shown in Figs. 5 and 6 to clear the door opening, the projection 6 will be accommo dated in the recess a, while the handle f will depend so that when desired the bar can be conveniently pulled down into its Working position shown in Figs. 1 and 2.

For the purpose of detachably securing the bar D in its upper and idle position, I prefer to employ the latch E. This latch pivoted at g, and its inner and comparatively heavy arm is provided with a depending portion h which rests between the inner side wall of the car and a strap 2' attached thereto, and is adapted to retain the bar D against the bar A. The outer arm of said lat-ch E is provided witha tail portion j, designed for the engagement of a hook-bearing rod or other device employed to raise the inner arm of the latch with a view to releasing the bar D precedent to pulling the same down through the medium of the before mentioned pendent handle f.

In addition to the bar D, the door fastening and supporting means comprises an upright bar F, upright strips G fixed to the inner sides of the door posts C and forming therewith rabbets 70, lower keepers Z and upper keepers m, carried by and projecting beyond the inner edges of the strips G, and keepers 29 carried by the bar F and project-- ing beyond the sides of the inner portion 1 thereof and located in a horizontal plane slightly above that of the keepers Z. The bar F comprises the mentioned inner portion 1" and a comparatively wide outer portion 8 against which the adjacent portions of the doors H are adapted to bear outward, as

clearly shown in Figs. 2 and 3. The lower end of the bar F is removably seated in a recess in the door sill t and between said sill and a fixed strip a, and, as best shown in Fig. 7, the inner portion 1" of the said bar is extended above the outer portlon 8 thereof 7 D. Vhen the bar D hen, however, it is large pieces of merchandise are to be moved therethrough, the bar D is swung inwardly and upwardly, whereupon it. will be disengaged and separated from the bar F, and

i then said bar F may be lifted out of its socket between sill z, and strip u, and stored away for future use.

To position the bar F and bar D for use, the manipulation described is reversedz'. e., the bar F is placed in the socket between sill t and strip a, and then, while the bar F is inclined slightly inward, the bar D is positioned between the notched end of the bar portion 1" and the flange to, after which the adjacent portions of the bars F and D are swung outward until they rest in a vertical position, whereupon the bar D will be seated between the notched portion and the flange w, and with its projection e in the notch '0, in which position the bar D will serve the purpose heretofore ascribed to it.

The doors H are preferably, though not necessarily, flat steel plates, and while I show the said doors as connected through chains I with the side wall of the car body,

-I do not confine myself to the use of chains or any other connecting means, since without affecting my invention the doors H may be entirely unconnected with the car body.

To put the doors H in the position in which the same are used, which position is shown by full lines in Fig. 1, it is simply necessary to place the doors, while in a position above the keepers ;0, against the rabbets 7c and the inner side of the outer portion 8 of the bar F. The doors are then slid down-- ward until they rest on the floor of the car body, and then, as will be manifest, the doors will be confined between the outer walls of the rabbets 7c and the inner side of the portion 8, on the one hand, and the keepers Z, m and p, on the other hand. When thus placed the doors will bear outward against the outer walls of the rabbets 7c, the portion 8 of bar F, and the bar D, and consequently outward movement of any portion of either door is efiectually prevented. It will also be manifest that the doors are securely fastened in position and are braced or reinforced and supported by the door posts, the bar F and the bar D.

When it is desired to discharge grain or other substance carried in bulk from the car body through the portion of the door opening controlled by either door, it is simply necessary to raise either door to a point above the keepers 72, and then swing or otherwise move the said door to the position shown in Fig. 5.

In Fig. 8, I illustrate a modified construetion in which a sheet-metal upright bar F of channel-form in horizontal section, is employed in lieu of the upright bar F, heretofore referred to, and the bar D (which may be made of metal, wood or other suitable material) is adapted to afford a bearing for flanges s on said bar F while the said flanges are designed, in turn, to afford bearings for the doors H whlch are confined thereagainst by keepers p on the lower portion of the bar F in the manner before described. lVith the exceptions noted, the modified construction is similar to that shown in Figs. 1 to 7; it being noted, however, that in said modified construction it is departing from the modifications may latch E so that said latch can be conveniently moved; the tail-portion j being preferably apertured for said purpose as shown in Fig. 6.

In both of the disclosed embodiments of my invention, the swinging bar is preferably a steel pipe of rectangular form in crosssection, this in order to secure both strength and lightness.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. In a grain door for cars, the combination of a car body having a door opening and door posts equipped with rabbets, and also having a socket located intermediate the posts; an upright bar movable vertically into and out of the socket and having a comparatively wide outer portion, an upwardly extending and notched inner portion and an upwardly extending outer portion spaced from said inner portion; a vertically swinging bar held against outward movement by the posts and constructed to seat between said upwardly extending portions of the upright bar and having a projection to seat in the notch of the inner portion and also hav ing arms pivoted to the posts, vertically movable doors that bear outward against the posts, the outer wide portion of the upright bar and the vertically swinging bar and are arranged in the rabbets of the posts, and keepers in the posts and other keepers on the upright bar and arranged in a different horizontal plane from those on the posts, for holding the doors against'the posts and the wide portion of the upright bar.
