To all whom, t may concern: I

, Be it known that I, JOHN W. HAWN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and usefullmprovements in Car-Doors; and I do declare the. following to. be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to the figures of reference marked thereon, which form a part of this specification.

My present invention relates to car-doors, and more Vparticularly to a door for use on railway-cars laden with grain or like freight which is loosely carried in the cars and is apt to escape through small openingslaround or under the ordinary door. Y

The object of m-y invention is to provide a device of .the class described which will oc@ cupy but a small space in the car when not in use, which may be easily and quickly posiv tioned when desired, and when so-positioned and locked will prevent the-escape `of grain therethrough.

My device while embodying these advantages is simple and economical in construction and comprises improved details of structure, which will be hereinafter described, and pointed out in the claims, reference being had vto the accompanying drawings, forming part of this specification, in which like reference-numerals refer to like partsthroughout the several views, and in vvhich-` Figure 1 is a front elevation of my door positioned on an ordinary grain-car. Fig. 2 is a horizontal sectional view on "the line m, Fig. 1. Fig. 3 is a vertical sectional view on the line g/ y, Fig. 1. Fig. 4 is a detail view of one of the latches. Fig. 5 is a detail view of one of the sliding hinges joining the upper and lower doors.

Referring more in detail tothe parts, 1 is the side of an inclosed or boX car such as is used on railways for carrying grain.

2 is the floor of the car, and 3 and 4 the jambs on each side of the door. Throughout the length and near the inner edge of jamb 4 is a groove or cut-out portion 5, protected on its inner side by a plate 6, which is secured to the inner side of said jamb. 7 is a plate secured to the side of 'jamb'4 adjacent to the door, partly covering groove 5 and having a slot therein to forma catch for one of the doorlatches, as will presently loe described. J amb 3 is formed with an angling inner surface 9, to which is secured a plate 10.

11 is a plate secured to the side of jamb 3 adjacent to the door and having a flange 12 at its inner end parallel with the angling surface 9 of jamb 3 and forminga recess between said flange and plate 11.

13 is the body of the door, to one edge of the outer side 'of which is'secured a plate 14, having a `flange 15 at its outer end, which is bent 'slightly outwardly and then continued a Short distance parallel with door-13, thereby providing a 'recess 16 between said flange and said door. The opposite edge of door 13 is provided with a plate 17, the outerl edge of which is4 curved outwardly and backwardly at an angle to said plate to form a hooked lip 18.v Secured to the top of door 13 by means of sliding hinges 19 is an auxiliary door 20, whichis provided at its edges with flanged plates similar to plates 14 and 17 on door 13. When door 13 is not needed, auxiliary door 20 is swung downwardly thereagainst and the whole is raised by means of a chain 21, which runs over a pulley 22, hung from' the top of the car, and is secured to a pin 23 in door 13. When the door has been raised, a ring 21.a on the end of chain 21 is slipped over a pin25 in one of the jambs and the lower end of the door raised to a seat on bracket 24, secured to the top of thecar, (shown in dotted lines, Fig. 3,) a positionwhich will not interfere with the loading of the car with bulky merchandise, although readily accessible when its use is desired. When it is desired to load the car with grain, bracket 24 is turned to permit thelower end of the door to fall, and by removing the chain-ring 21 from pin 25 the door is lowered until it rests on the floor of th'e car, the`plates 17 and 14 lbeing a little to the sideof jambs 3'and 4. The door is then pushed forward and sidewise, the iiange 15 of plate 14 entering the vertical groove 5 in jamb 4 and the' hooked lip 18 of plate 17 engaging the iange 12 on plate 11. 'Latch 26, which is pivoted to door 13, is turned until the hooked end 27 thereof enters and bears against the top of the slot in plate 14, and the keeper 23 is swung inwardly till its lower end bears against the outer upper edge of latch 26 to retain same in its locking position. On the opposite edge of door 13 is pivoted a latch 29, the finger 30 on the outer end of which is adapted to enter and bear against the top of a slot in plate 11 or against a pin on said plate, while the angling finger 31 thereon is forced against the face of said plate. Latch 29 is held in its locking position by a pivoted keeper 32 similar to keeper 28. When said latches have been secured in the positions described, the hooked end of latch 26 and linger 30 of latch'29 `prevent the raising of door 13, while the angling finger 31 prevents the lateral movement of same.

Should it be desired to load the car above door 13, auxiliary door 2O is raised and pushed into position by sliding it along hinges 19 until the plates on its edges enter the groove 5 and engage the flange 12, as described in connection with door 13, when said door 2O is locked by latch 33 being forced against jamb 3.

34 represents brackets on door 13, forming seats against which to place a bar in opening the door.

As can be readily seen from the drawings and description, it will be impossible for any grain to escape between the sides of the door and the jambs or between the bottom of the door and the floor of the car, as when the latches are secured in their locking positions a close joint is formed on the sides and the door is held tightly against the floor of the car.

I do not wish to be understood as limiting myself to the exact details of structure herein shown and described, inasmuch as the same may be varied without departing from the spirit of my invention.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a device of the class described, the combination with a pair of jambs, one of which is provided with a vertical groove the other having an angling inner face with a hooked plate secured thereto, of a door adapted to fit over and impinge against said jambs, a plate secured along said door adjacent to one of the side edges thereof and having an angling flange on the outer edge thereof adapted to enter said vertical groove, a plate sccured along said door adjacent to the opposite side edge thereof and having a hooked lip along its outer edge adapted to engage the hooked portion of the plate on said angling jamb, substantially as set forth.

2. In a device of the class described, the combination with a pair of jambs, one of which is provided with a vertical groove the other having an angling inner face with a hooked plate secured thereto, of a door adapted to fit over and impinge against said jambs, a plate secured along said door adjacent to one of the side edges thereof and having an angling flange on the outer edge thereof adapted to enter said vertical groove, a plate secured along said door adjacent to the opposite side edge thereof and having a hooked lip along' its outer edge adapted to engage the hooked portion of the plate on said angling jamb, said door being adapted for vertical movement along said jambs and for lateral displacement from its position thereagainst, and means for holding said door to prevent vertical or lateral movement thereof, substantially as set forth.

3. In a device of the class described, a door, a pair of jambs, means on said jambs for retaining said door in a vertical position, slotted plates on the sides of said jambs, pivoted latches on said door having lingers at their ends adapted to engage slotted plates on said jambs, and an angling liange on the end of one of said latches adapted to bear against thc face of one of said jambs, and keepers on said. door for retaining said latches in their locking position.

4. A device of the class described comprising a pair of jambs, in one of which is avertical groove, a plate on the opposite jamb having an angling iiange thereon, a door 13 having plates along' the edges thereof, one of which is adapted to lit within said groove and the other to engage said angling lange, and an auxiliary door swung on sliding hinges at the top of said door 13 and having plates on its edges corresponding with the plates on door 13.

In testimony whereofl I ailix my signature in presence of two witnesses.

JOHN IV. laIAlVN.
