To allwhom tmag concern,"
Beitknown that 1, Jaoon J LIBBY, a c ty zen of the United States of America,res1ding at Fostoria, Seneca County, Ohio, have inventedxnew and useful Grain Doors, of
. which thefollowing is a specification.
This invention relates to closures of a readily removable type,. for loin openings or doorways.
This invention has utility when 1ncorporatedas a grain door forbox cars of railys-1 a,
4 Referring'to the drawings: Fig. 1 is a side elevation of car having; an embodiment of the invention incorporated therewith; Fig. 2 is a plan view of'an assembled sectional unit;
Fig. 3 isa perspective view of the cleat carrying side of one of the sections of the section of the unit from that shown in Fig. 5 isa fragmentary view on an enlarged scale showing in plan the'hook and seat engagement, as well as the button holdin g assembly features,
A railway box car 1 is shown as having a side doorQ slidable clear of the doorway or opening 3 having parallel sides 4.
A. door section 5 is shown as having a cross cleat 6 slightly spaced from an end 7 j provided with a pair of projections or hooks 9 to detachably engage with seats 10 in plates 11 anchored by rivets 12 to the inner face13 of a second door section 14. This second section 14 has a cleat 15 on its outer side, similar to the cleat 6 of the section 5, with door frame engaging points or prongs 8, also protruding therefrom, similar to the prongs 8 of the cleat 6. The two rows of seats 10 extend inward from the cleat 15, but upon the opposite side of thesection 14. Beyond these seats 10 and still more remote from the cleat 15, this door section 14 has a pair of parallel slots 16.
The first door section 5, isv shown as having a pair of pins 17 fast therewith, provided with swiveled cross-barsorbuttons 18, which in protruding after insertion through the slots 16, may be turned crosswise of such a railway box 1 Fig. 4; is a perspective view of the other I door unit.
slots 16, and thereby readily serve as holding means for maintaining the two sections of the door unit in assembled parallel relation. The hooks'9 as engaged in diflerent seats 10 provide a ready assembly means for varying the effective length of the unit to meet conditions of varying widths of doorways- In practice, when a car is cleaned out and ready'to be loaded with grain, or other bulk material, a pair of unit sections are taken, the hooks9 being entered in seats 10in such region that as the slightly buckled sections are "forced into parallel relation with'the' bethe'width adjustment, these button holding means may be turned for looking the lNith small or very fine bulk material, gunnyysacking or other backing may I be placed along the'door frame, the threshold and between the units as built up, to such height as "may be desired in closing the doorway. However in top groove 19 a rope-20 may be partially embedded to project and seat-in bottom groove 21 of the next section to packL-the joint. 'When the loaded car reaches its destination and it is desired to unload the same byyallowing the material to flow from the door, there is no occasion to mutilate the car or the door-units. In fact, the most ready way is to turn the buttons 18 to align with the slots 16, and then with little effort the section 14; may be swung outward at an easily controlled rate for governing the discharge stream, as the first section is also drawn outward by the hooks 9 still engaging the seats 10. This outward opening of the door unit, automatically withdraws the points 8 from embedded relation. Assuming that this isthe lower door unit which has been removed, the flowing of the bulk material in discharge does not result in a toppling down of the upper sections,'105 I which when built of wood and faced or iii' ing the sections together to approximate the width of the opening between the parallel sides thereof, when the sections are in-parallel relation, there being a lock for said connecting means which in the adjustment of the sections is shiftable as to only one-of the closure sections.
2. A grain door unit'for railway box cars embodying a pair of sections, e'ach of less length than the width of the car doorway, and a hinge connection between the sections :adjustably-and detachably unitingthe sections, there being a lock for said connection mounted on one of the sections indevdependently-of shifting therealong.
3. A-doorsection having a projection, a
second door section having a series of seats engageable by the pro ect1on m ad ust1ng the assembly of the sections to different widths of doorways, said sections being provided with embedding means for engaging opposite sides of a door trame and means adjustable along one-oi": said sections only for drawing the sections in position against disengagement of the projection from a seat and simultaneously mounting the sections in the frame by driving the engaging means into the frame. i
4. A door section having a terminal project-ion, a second door section having a row of seats which in setup position of the section extend transversely of a doorway, said sections being provided "with embedding means vtor engaging opposite sides of a door frame, and means carried by the projection carrying section adjustable along one of said sections only for drawing the sections assembled in parallel relation with the projection engaging a and simultaneously mounting the-sections in the frame by driving the engaging means into the frame.
5. A sectional grain car door unit embodying a-pairof hinge connected se'ctions having their remote ends provitiled with cross cleats spaced inwardly i'romsuch ends, anddoorway frame engagingprongs carried by said sect-ions adjacentsaid cleats, said pair of sections being adjustable tor Width, and a lock for the hinge fixed as to onev of said sections. a
6. A rain car door unit embodying a pair of sections for assembly with each other and each provided with a cross cleat spaced from the outer end thereof, the other end of one of said. sections being provided with a pair of hooks, the other sectionbeing providedwith two rows of'seats extending away irom its cleatand engageable by the hooks in assembling the sections into parallel'relation to have the cleats approximate a doorway width and the projections beyondthe cleats engage a doorframe on the inner side, said seat carrying section having more remote from its cleat than said seats, apair of slots, and buttons carried by the hook carrying section to protrude through said slots and shittable to lock the sections .in parallel relation, and releasable from outside the door for outward swinging of the door in door unit removal.
