Application --fi1ed March-s, 1923. -Seria1 N0. 623,800.

To all whom it may con-061%:

Be it known that 1; JosErH DRAKE, a citizen of the }United States of America, and a; resident of Blue Rapids, in the county of Marshall'and State of 'Kansas, have'invented "a new and Improved Grain-Gar Door, of which the following is a de scription.

My present invention is'desi gned more particularlyas an improvement on-the grain car door forming the subjectmatter of my Patent Number 1 ,450,842, granted April 23, 1923, and an application filed by hie-"September 14, 1922, Serial Number 588,193.

The invention forming t/he subject matter of the patent and "application referred to comprisesan assemblage-including a main built-in'car door and an auxiliary door at the bottom ofthe main door.

The: present invention {is characterized by a. novel auxiliary door andits appurtenances and the -geI1'er-al object of the invention is toprovide an auxiliary door having novel means for engaging the main door and maintaining theauxiliary door in position while bracing't'he main door as 'well as to provide on the auxiliary door novel means to receive a bar or lever for workingthe auxiliary door-loose for thedischarg'e of the contents of the car.

Reference is to be had to the accompanying drawings iorminga part ofthis specification; it being understood that the drawings are merely illustrative of one example of the invention.

Fignrel is an exteriorview of "a grain car door embodying my invention showing the same emplaced;

Figure 2 is a viewshowingthe "auxiliary door in plan' and 'with an end thereof in horizontal section and showing a portion ofthe'car body in horizontal section online 2-2, 'Figure 1;

-'Figure 3 is a itac'e view of one of the bar *sections -a pp'urtenant to the auxiliary 'doorand having supporting and bracing relation to the main door;

Figure 4 I is --a transverse vertical section on the line M, Figurel;

Figure 5 is a-pe'rspective view of a portion of the auxiliary door;

19 applied to the face 'of door -10.

In carrying out 'm'y invention in accordance with the illustrated example iny improved au-x-ilia ry door designated generally bythe numeral lO haS a width tobe disposed E in 1 the usual Y door opening- 11, of a car 1'2't-o overlap the'sides of the'door frame at them interior of the car, saicLa-uX- iliary door being positioned at the 'bottom of the'opening beneath the main door 13 which may be of any approved construction. In'theauxiliarvdoor 10 at each end-is a series of recesses or depressions Y 14 extending from the face of said door and advantageously through plate '15 5 applied thereto, said plate and the series of holes being oblique.

At the'centerof theauXiliary door 10 at the outside is-a broad vertical slidab'le element 1 6, said element inthe raisedp'osi- Mon-overlapping the lo'Weredge portion of main door 13. In element 16 F isa *vertic'al slot l7 through which a bolt-18 pa'sses, the bolt passing also-through horizontal strap The ends a of the strap 19 are fastened in *any suitable manner to vertical strengthening plates {20 applied to *the door 10 inward from the ends thereo'f. A plied --to door 10 also at the front are vertically disposed angle pieces- 21 w hi'ch l ie 'close to {the-sides of-element 16 to g'uidethe sa me.

- At the top of door '20 l-prov-ijde,*as in my previous constructions re'ferred to, "bar sections 22 having studs 23 to be taken hold of in manipulating said -bar sections lengtlr w ise. The bar sections are accon'ifmo'dated in a longitudinal 'rabbet 11'0 -at the top of door "1-0 and lie behind theqangle pieces 21 and plates 20. Transverse bolts pass through the plates -20 "and through oblique slots 25 i-n bar sectionsf22-so that a longitudinal movement of the said bar' sections will cause" the same toniove vertically byreason efthe oblique s'lots and the bolts. On the door 10 at' the en ds oft he rabbet llO'are inclines '26 tobeengaged by the outer ends of the bar sections 22. @n the door It) at the bottom of-the rabbet l10 are produced vertical shoul'ders 27' and correspond- -ing"'notches 122 are formed in thelower edges of the bar' 22, see Fi g'ure so that said shoulders 27 constitute stops for the bar sections 22 in the lowered position of the latter.

In practice the door 10 is placed in the opening across the doorway at the bottom beneath the main door 13 at the inner side of the door frame and the element 16 and bar sections 22 are then raised to engage the main door after which the nuts 28 of bolts 24: and the nut 29 of bolt 18 are tightened, holding the auxiliary door 10 firmly in position. The raising of the bar section 22 causes the outer ends thereof to overlap the door frame whereas in the lowered position the said bar sections will clear the door frame. To remove the door 10 the bar sections 22 are lowered to disengage the ends from the door frame and a lever bar A is employed by entering the end thereof in that hole 14 of a series which is nearest to the adjacent door frame so that the lever A may be caused to move the door 10 endwise. The endwise movement of the door 10 is made progressive by engaging the lever bar A in successive recesses 14 until the said auxiliary door is clear of the main door frame, whereupon the auxiliary door may be readily moved outwardly.

In the present application the bar sections (22) are not claimed broadly. The generic invention residing in said bar sections is claimed is an application filed by me September 14, 1922, Serial Number 588,193. The bar sections 22 having a length to over lap the door frame form no part of the present invention and are not incidental to the present invention. The said bar sections thus arranged to overlap the door frame form part of the invention forming the subject matter of an application filed September 14:, 1922, and pending concurrently herewith.

The car is prepared for loading as follows: The auxiliary door 10 is placed in position as described and the bar sections 22 are moved to the raised position. Then the first ordinary grain door section is placed in position resting upon the sections 22 and said ordinary grain door section is then nailed solidly to the doorway post. Subsequently, the doorway is built up with rough doors as high as desirable. I would state that when the bar sections 22 are raised and the slide 16 moved to the raised position, the

nuts

28 and 29 are tightened up.

'lVhen the car is unlocked and the door is to be taken out to discharge the cargo, the slide 16 and the bar sections 22 are lowered. The lever bar A is then employed to disengage the auxiliary door from the car frame to permit removal of said auxiliary door. The bar sections 22 are so formed and arranged as to overlap the door frame when the bar sections are raised and form part of the invention claimed in the present application, the illustrated form in the present case lending itself particularly to the projection of the bar sections overlapping the door frame to a material extent.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictlyto the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim:

1. An auxiliar grain car door adapted to be emplaced in the doorway of a car heneath a main door, said auxiliary door having a longitudinal series of recesses at an end thereof adapted to receive the end of a lever for prying the auxiliary door and wise from its position in the doorway, the outermost recesses being adjacent the end of the auxiliary door whereby to be overlapped by the framework of the car and to be ex posed in succession as the lever is successively engaged with the recesses.

2. An auxiliary grain car door adapted to be emplaced in the doorway of a car beneath a main door, said auxiliary door having an oblique longitudinal series of recesses at an end thereof adapted to receive the end of a lever for prying the auxiliary door endwise from its position in the doorway, the outermost recesses being adjacent the end of the auxiliary door whereby to be overlapped by the framework of the car and to be'exposed in succession asthe lever is successively engaged with the recesses.

3. An auxiliary door adapted to be placed in the door opening of a car beneath the main door, a vertically slidable element mounted on said door movable to or from a position projecting above said auxiliary door for overlapping at a main door, and bar sections at each side of said vertical element at tl e top of the door and movable vertically to engage the main door to temporarily support said main door until the latter i nailed fast, said bar sections having a length to be given a position overlapping the main door frame.

45. An auxiliary door adapted to be placed in a door opening of a car beneath the main car door, angle pieces on the ClOOlilt the front and spaced from each other forming a vertical guideway, an element on the door slidable. between said angle pieces, a strap extending across said angle pieces and across said element and having a slot and pin connection with said element to permit the vertical sliding of said element, said element being movable to a position ,to project above the auxiliary door to overlap the main door.

An auxiliary grain car door having a longitudinal rabbet on the upper edge thereof, bar sections in said rabbet and formed with oblique slots, transverse bolts passing through said slots and through fixed parts of said auxiliary door, said bolts and slots adapted by a longitudinal movement of the bar sections to give a rising and lowering movement to said sections, inclines on the auxiliary door at said rabbet on which inclines the outer ends of said bar sections 10 rest, and stop shoulders in said rabbet, said bar sections having notched portions to engage said stop shoulders in the lowered position of said bar sections.
