T '0 all to hem it may concern:

lie it known that I, Jaeon S. Barman, citizen of the United States, residing at Kansas tity. in the county of Jackson and State of fitissonri, have invented certain new and useful improvements in tonibined Grain- !)oors and Car-Doors, of which the following a specification.

My invention relates to a combined grain and car door; and one of my objects is to provide a door whicn will perform the double function of a graiindoor and an ordinary candooi'. so that each side of a car need only he provided with one door instead of two as is (cu tomary when the ear is equipped for hauling grain.

Other objects of the invention will hereinafter appear, and in order that it may be tally understood. reference will now be made to the accompanying drawings, in Whieh:

Figure 1 represents a broken side elevation of a box-car equipped. with my improved door. the latter being in a closed position. Fig. 2 is a vertical central section on line li ---llt oi Fig. 1. Fig. 3 is a detail croas seetien'of the door-jambs of the ear and my improved door, the latter being partly disengaged from the former preparatory to opening the door. is a broken side elevation of the (fit-i with my improved door in an open position. Fig. 5 is a cross section on line V--V ot'i ig. l.

1 designates" a box-car provided at its sides with doorways 2.

3 designates a pair of door-jainhs at oppo site sides of each door my. Said doorjanihs are made oi sheet-metal having veriieal pockets 4 pressed therein to receive the vertical edges of the. door, as shownin Fig. 5.

(i designates my improved door, which consist (it a ma n section 7 and a pair o't flaps which latter are secured to the vertical sides of the main section by it and adapted to swing' inwardly as shown in Figs, 3-3 and 4 to permit the door to open. The tree edges of tlaps 8 are tapered at their upper portions 10 so that said edges maybe more readily inserted in pockets et when closing: the door.

Section 7 of the door is provided at its upper portion with an opening 11, which is normally closed by a Wicket 152 secured by hinges 13 to the. upper side of raid ening;, through which latter the car may he tilled \vith grain when the door is in a closed tion.

Door 6 is suspended from a pair of hangers H. each of whieh consis'a of a hood 15. a hrack t it; seen red to the upper portion of section T, and a lint; I? pivotally connected. at its ends to the underside of hood to and the up er side of bracket 16 so that: section 7 n'iay swing outward to the position shown in Fig. 3, prepa atory to opening the door.

Hood is provided with a pair of grooved rollers 18 arranged to travel upon a traek l9 suitably 'zeured to the upper portion of the ear. Said track is circular in rro as-seetion so that the 'JOOVQtl rollers may rock laterally thereon and permit the lower portion of the door to swing outward as ndicated by the dotted lines a. Rv suspending the door in this manne it i evident that the instant it is unloel immediately forced outwardly by the grain within the ear hence there \vili he no necess ty to employ a ertnvhar or other inzple lneut apt to injure the door in opening; the

same. t

The door is locked in closet position to transverse bar 20 engaging poiets pivotaliy secured, at its eentrat t sectimi T by a holt fit. Ti 3 are rounded so that when. tin heveled sides t ot the l said together with the door Wili i) need inward and press flaps 8 ti htly against the inner sides t" of the pockets to pro cage of grain at these points.

The pivotal inovenn-nit of harhy a pair of loops seei'tred to section and when, it is desired to .toelt the car, sai bar is held in a horizontal position, see l. by a latch 23 pivoted to the door and revided with a eurved upper end i t to pass throng: i s the nut the hat. provided with a apl'- V 1 hen dosired the Wire of a there through and around the adgacent loop 22, as Will he readiiy understood.

26 designates a handle secured to the lower portion of section 7 to otter a convenient. grip When opening or closing the door.

27 designates av retaining ip secured by a hinge 28 to a strip 29 for the purpose of forming a grain-tight joint between the lower edge of the door and the threshoid of the doorway. Said retaining-strip may 2G is limitedt, l l

it Will he held against thelower portion of door 6 by any suitable fastening device, a pin 30 pass ing through a staple 31, being shown. Pm 30 is secured from loss by a small cable 32 attached to handle 2". Staple 31 is secured to the lower portion of the door and extends through an opening in the retaining-strip, as shown in Fig. l.

When it is desired to open the door, pin 31 is removed from the staple and the retainirig-strip 27 is lowered to the position shown in hi g. 1. Latch 28 is then swung out of engagement with the lower end of bar 20 so that the latter may swing on its pivot to disengage its extremities from "the pockets 4-.

1f the car be loaded with grain the pressure thereof will force the door to swing out-- ward at its lower end, as hereinbeifore described, but if it be loaded with merchandise;the door can be pulled outward bodily to clear the doonjambs and the side oi" the car. When the door is pulled. out in this manner links 17 turn on their pivots so that the door may be slid backward to uncover the doorway without interfering with the side of the car, the foremost flap being previously foldedback against the inner side of sections 7 indicated by dotted lines, Fig. 4, to reduce the distance at which the door need be pushed backward to fully uncover the doorway 2. The backward movement of the door'is limited by a stop 33 secured to the side of the car.

Having thus described my invention, what i. claim I i. A. car-door consisting of a main section and pair oi flaps hinged to the vertical edges thereof, metallic .door-jarnbs at the sides of the car door-way having "sockets to receive the free edges of the laps, said ochets having beveled sides, and means for ocking the door in a closed position, the

extremities of said means being arranged to enter the pockets and engage the beveled sides thereof.

A car-door consisting of a main section 'and a pair of flaps hinged to the vertical edges thereof, door-jambs at the sides of the car-doorway having pockets to receive the free edges of said flaps, said pockets having beveled sides, and a bar pivoted to the main section of the door adapted to engage the beveled. sides of the pockets, substantially as described. I

3. A car-door consisting of a main section and a pair of flaps hinged to the vertical edges thereof, door-j ambs at the sides of the car-doorway having pockets to receive the free edges of said flaps, said pockets having beveled sides, a bar pivoted to the main section of the door adapted to engage the beveled sides of the pockets, and a latch pivoted to the door for securing said bar in a locked position.

A car-door consisting of a main section and a pair of flaps hinged to the vertical edges thereof, door-jambs at the sides of the car-doorway having pockets to receive the free edges of the flaps, said pockets having beveled sides, means for locking the door in a closed, position, the extremities of said means being arranged to enter said pockets and engage the beveled sides thereof, members for carrying the door, and means pivoted to the door and said members whereby the door may swing outward. bodily to disen its flaps from the pockets.

in testimony whereof I afiix my signature in the presence of two witnesses. JACOB S. BENDER.
