JACOB S. BENDER, OF KANSAS CITY, MISSOURI.

GRAINJDOOR FOR BOX-CABS.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Anplication filed December 8. 1906. Serial No. 346.862.

To all whom it may concern:

Be it known that I, JACOB S. BENDER, a citizen of the United States, residing at 1857 Jefferson street, Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Grain-Doors for Box-Cars, of which the following is a specification.

My invention relates to improvements in grain doors for box cars, and my object is to produce a door of this character which will prevent leakage of grain, will successfully resist the pressure of the grain, and'may be easily opened regardless of said pressure The door embraces two sections, the upper one of which is slidably and pivotally mounted, while the lower one is hinged, so that it may be let down preparatory to unloading the car.

In order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which Figure 1 shows a broken interior'view of a box car provided with my improved grain door. Fig. 2 is a broken exterior view of the same. Fig. 3 is a broken cross section on line III-III of Fig. 1. Fig. 4 is a broken horizontal section on line IV-IV of Fig. 1. Fig. 5 is a broken horizontal section on line VV of Fig. 1. Figs. 6 and 7 represent a pair of castings forming part of the invention.

In carrying out the invention I provide a door consisting of an upper section 1 and a lower section 2. Section 1 is strengthened by transverse corrugations 3, so that it may be made of thin metal in order to reduce its weight as much as possible, and yet give it the requisite strength to successfully resist the strain imposed thereon by the grain. It is provided at its ends with vertical flanges 4, which snugly fit against the inner sides of the door posts 5, and thus prevent leakage of grain at these points. Said upper section is also provided with a pair of sheaths 6 for the reception of a pair of slotted links 7, upon which the upper section is suspended, it being normally supported at the lower ends of the links by bolts 8 eX- tending through the sheaths, the slots of the links and the section.

The upper ends of links 7 pivotally engage a pair of eye-bolts 9, while their lower ends are formed into inturned hooks 10, which slide within and engage the lower ends of the sheaths when section 1 is slid upwardly on the links preparatory to raising it to the position shown by dotted .lines, Fig. 3, where it is supported by hooks 10 pivotally secured to the carlines 11.

By first sliding sections 1 upwardly it is obvious that their adjacent ends will not overlap when swung to the position shown by dotted lines, Fig. 3. Hence they may be easily engaged with or disengaged from said hooks and either one may be let down without disturbing the other.

When in a lowered position the upper sec tion overlaps the lower section 2 against which it abuts its entire width to prevent leakage of grain between the two sections. Section 2 is reinforced with a pair of inwardly turned end flanges 12 and an outwardly turned longitudinal flange 13 along its upper edge. It is further reinforced with a longitudinal strap 14, which unites hinge members 15, integral with the lower portion of section 2. Hinge members 15 are secured to similar members 16, integral with a threshold plate 17, by a pintle 18.

19 designates a pair of castings secured to the floor of the car and the lower ends of posts 5, and provided with inclined pockets 20, to receive flanges 12, and thus prevent leakage of grain at the ends of the lower section. Said .castin s are also provided withreversely-dis posed eepers 21 22 for the reception of the ends of a bar 23 employed to reinforce and lock the lower section in a closed condition, see Figs. 2 and 3.

Bar 23 is pivotally secured by a bolt 24 to the upper central portion of section 2, so that when the latter is closed, said bar may be swung to the position shown in Fig. 2, and thus engage behind the keepers, grooves 25 being provided at the rear thereof for the reception of the terminals of the bar.

The swinging movement of bar 24 is limited by a pair of loops 26 on member 2, and when in engagement with the keepers its movement is further limited by a latch 27, so that its ends cannot disengage the keepers until said latch is swung to an inoperative position. Latch 27 is pivoted to section 2 by a pin 28 adjacent to one of the loops, so that the latter will support the latch in its operative position, when it is swung into engagement with said loop. See Fig. 2.

Both sections set in from the path of the outside door A, with which box cars are usually equipped, and the lower section is so hinged that when opened it will swing down way of the outside door.

to a perpendicular position and be out of the Thus when the car is loaded with merchandise, which does not require a tightly fitting door, my sections may be swung to their inoperative positions, so that only the outside door A will have to be opened when it is desired to gain access to the interior of the car.

Section 2 is made considerably shorter perpendicularly than section 1, so that when the car is loaded with grain the bulk of the weight against the door will be upon the upper section. Hence the lower section may be readily opened when it is desired to unload the car, so that sufficient grain may be taken from the opening thus left to allow the upper section to be swung upwardly out of the way and give access to the interior of the car, preparatory to unloading the remainder of the grain.

Having thus described my invention, What I claim is 1. A grain door for cars having a hinged section, loops secured to said section, a bar pivoted to the section for locking the same, the ends of said-bar extending through the loops, keepers adapted to be engaged by said ends and a latch pivoted to the section adapted to be turned into one of the loops beneath and hold the bar in a locked position.

2. A grain door for cars consisting of an upper section, a hinged lower section provided at its upper ends with inturned flanges, castings secured to thedoor posts of the car and provided with pockets for the reception of the flanges and with reversely disposed keepers, and a locking bar pivoted to the outer face of said lower section with its ends adapted to engage behind said keepers.

3. A grain door for cars consisting of an upper section, a lower section provided along its upper edge with an outturned reinforcing flange and along its lower edge with hinge members, a threshold plate to which the hinge members are pivotally secured on a line outside the plane of the upper section, castings ings on the door posts provided with inclined pockets adapted to receive said flanges and with oppositely disposed keepers laterally beyond said pockets, and a locking bar centrally pivoted to the lower section with its extremities adapted to engage between said keepers when said flanges are in place.

5. A grain door consisting of a lower section, an upper section provided with vertical sheaths, slotted links arranged in said sheath and provided with inturned hooks for engaging the lower ends thereof after the upper section has been slid. upwardly, bolts passing through the upper ends of the sheaths, the slots in the links, and the section, means above the doorway to which the links are pivotallysecured so that they may swing upwardly with the upper section, and hooks for supporting said upper section in a raised position.

In testimony whereof I afliX my signature, in the presence of two witnesses.

JACOB S. BENDER.
