GRAIN-CAR noon. i

Application filedrseptcmber l l, 1922. Serial No. 588,193.

to provide an auxiliary grain car door'to be' employed beneath any approved main car door, said auxiliary door adapted to be detachably secured at its ends to the sides of the door frame and provided with an opening controlled by a closure so that the auxiliary door while in positionwill permit the flow of grain or other bulk material and be bodily removable when su'flicient' of the materialhas run from the car.

The present invention is designed more especially as an improvement on the grain car door forming the subjectmatter of an application filed by me March 17 1922, Serial Number 544,501 and has for its prime object to provide on the auxiliary door, rest means for the main built-on grain door, said object and others as will appear being attained ina manner and by means hereinafter fully set forth.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is an exterior view of a grain car door embodying my'inventlon showing the same emplaced;

Figure 2 is a horizontal section on the line 22, Figure 1, showing the auxiliary door in closed and fastened position;

Figure 3 is a view similar to Figure 2 but showing the closure of the auxiliary door swung away from the opening in'said door and showing the sections of the auxiliary door flexed;

Figure 4 is a longitudinal vertical. section taken on the line 4-4, Figure '5;

Figure 5 is a transverse vertical section on the line 5 5, Figure 1.

In. carrying out my invention in accordance with the illustrated example my improved auxiliary door designated generally by the numeral 10 has a width to be disposed in the usual door opening 11 of a car 12 to overlap the door frame, said auxiliary door being positioned at the bottom of the open ing beneath the main door 13 of any approved construction;

Said auxiliary door includes two sections 14 contacting at their opposed ends and a closure 15 for the space or opening presented at the juncture of said sections, said closure 15 being hinged as at 15 to one section 14 and adapted to overlap the other section when the two sections are alined. The sections 14 at their opposed ends have respectively upper and lower hinge leaves 16 having face members 16 rigid therewith and connected by hinge pins 17 sothat the door may break or flex outwardly at the center. y

i In accordance with the present invention I provide on the auxiliary door composed of the sections 14 bar sections 20 each having slots 21 extending obliquely, there being a pair of such slots in each bar section 20, the slots 21 in a section being opposite to the slotsin the other section. Said slots receive transverse pins 120 passing through adjacent fixed parts of the auxiliary door sections 14. Knobs 121 serve as handles for sliding the bar sections 20. Said bar sections 20 aredisposed on the auxiliary door win the vertical plane of the built-on grain door 13 and may be moved longitudinally to cause the engagement withthe pins 120 at the slots 21 to raise or lower the bar sections 20 for contacting with the grain door 13 at the lower edge or said sections 20 may be so moved as to disengage the grain door 13. The sections 20 constitute a rest for the door 13. i

In order to lock the auxiliary door with the sections 14 alined and the closure 15 swung to the closed position between the said sections, I provide a lock bar 22 of a length to extend horizontally across the closure 15 and overlap the sections 14. Said bar is swingably secured at one end as by a U-bolt 23 which passes through one door section 14 and through reinforcing plates 24 applied to said section at the inner and outer surfaces thereof. At the opposite end the lock bar 22 is adapted to beheld by a latch 25 hinged as at 26 to the opposite door section. The bar 22 is U-shaped or channeled in cross section and accommodates is in the latching position against the bar 22.

\Vith an auxiliary door constructed as describedthe same is placed in position in the doorway at the bottom. When the grain or other bulk material is to be discharged the lock bar 22 is released'and the'closure 15-is swung on its hinge to the open position to permit the material to flow outwardly between the door sections 14. The auxiliary door 10 is removable bodily, the removal being effected by flexing the door at its hinge 17. Restsections 20 arelowered from engagement with door 13 in removing auxiliary door 10." v I The auxiliary door 10 is rounded or bevelled at the lower edge as at 10 and at the upper edgeas at 10*, the lower bevel engaging the sill plate 12"* provided on the car 12 of the door opening 11' as usual, and the upper bevel being presented to' the lower edge of the main door At the top the closure 15 extends above the auxiliary door 10 and its hinge member 16 to a height tooverlap the main door 13% A block 28 is-secured tothe floor of the car 12 just inward from the plane of the auxiliary door 10 at the medial line of said auxiliary door to constitute a stop' in the placing of the door in position beneath the main door 13. V

The car is prepared for loading as follows; The auxiliary door-'10 is placed in position as described andthe bar sections 20 aremoved to the raised position. Then the first ordinary grain door section is placed in position resting upon the sections 20 and said ordinary grain door section 'is then nailed solidly to the doorway post.

Itwill be'observed that the slots 21 are at only a slight angle and materially within the angle of repose for which reason there is no tendency whatever of the plates-to be moved to alowered position under the weight ofthe main door 13. v

I would state inconclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit' myself strictly to the exact details herein illustrated;- si'nce, manifestly, the same can= be considerably varied without departure from the spirit of the invention as definedinthe appended claims.

Having thus described my invention, I claim 1. Anauxiliary grain car door adapted to be detachably secured at its ends in a door opening beneath a main door, said auxiliary door including sections'hinged together and presenting an opening therebetwecu, a closure for said opening hinged to one of said sections and movable to close or open position, and means on said sections of the auxiliary door movable in a vertical plane to engage the maindoor above and constitute a support therefor until said main door is nailed in position.

2. An auxiliary grain door adapted to be det'achably secured 1n the door opening otagrain ca'r beneath'the main door,-said auxiliary door having means to afford. temporary support for the main door,said'means being movable on the auxiliary door and into engagement with the main door to constitute a temporary support thereforuntil said main dooris nailed in position.

3; An auxiliary grain door adapted to be detachably secured in the door opening oi. a grain car beneath the main door, and a support for the main door mounted on the auxiliary door, said rest having oblique slots and the auxiliary doonhaving pinspassing through said slots sothat the movement of saidsupport will serve to-move the same into contact with the bottom of the main door to hold-said main door temporarily in position unt i l. nailed.

1. An auxiliary grain car door adapted to-be detachably secured inthe door opening of the g rainear beneath the main door, said auxiliary door including sections hinged to gether, and an element on-eac'h-section of the auxiliary d'oorat the top and movable in avertical plane to'contact with the main door and constitute a support therefor or to be lowered out of contact 'with the main door, said element each having a pair of oblique slots therein and the auxiliary door sect-ions having pinspassing through said slots so that a longitudinal movement of said elements will impart vertical movement to engage said main door for temporarily holding said main door until nailed.
