To all @071 am it may concem:

Be it known that we, Aaron W. WILSON and IRWIN E. RICE, citizens of the United States, residing at Casper, in the county of atrona and State of Wyoming, have invented certain new and useful Improvements in Car-Doors, of which the following is a specification.

The present invention relates to improvements in grain doors for railway cars, ordinarily known as box-cars, of the general type wherein a plurality of door elements or sections are. so mounted that they may be con veniently moved to positions to open or close the door opening of the car.

An important object of the invention is to above mentioned char acter, whereby the door or door-sections, when not in use, may be stored within the box-car, inan out-of-the-way position, in a manner to occupy the minimum space.

A. further object of the invention is to provide guide means for holding the door or door-sections in their closed positions, such guide means being adapted to be moved oilt of the way when the door opening is uncovered to provide the maximum clearness space in proximity to the door opening.

A furtherv object of the invention is to e abOW-B mentioned character, whi ch are simple in construction, inexpensive to manufacture, convenient in use, and may be installed upon almost. any boxcar without material alteration to the construction thereof. 1

()ther objects and advantagesof the invention -will be apparent during the coursr of the following description.

In the accompanying drawings forming part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of a box-car equipped with apparatus embodying our invention, Fig. 2 is a transvere: 22; View online 22 3 is a similar View taken ,on -1,Fig. 4. is a vertical longitudinal sectional view taken on line 44 of F 2, and, Fig. 5 is a horizontal longitudinal sectional view taken on line 55 of Fin. 1.

in the' drawings, wherein for the purpose of iilustratic-n is shown a preferred embodiment of the invention, the numeral desigbox-car, preferably designed to carry grain ar the like. 1 This box-car is proin Fig. 5.

preferably oppositely arranged occurring at one side of the posts 14:. When the door openings are uncovered, for the purpose of unloading the car, the track-sections 12 are swungawayfrom the posts 14, to occupy positions. within the recesses 16, to afiord the maximum cle'arness space in proximity to the door openings. When the car is loaded with grain, as it is gradually unloaded the door elements 27 are movedup into the horizontal tracks one at a time. When thecar is practically empty the last door section is moved to the horizontal tracks, thus enabling the tracks 12 to be swung to the inner position, as clearly shown As clearly shown in Fig. 5, when the track-sections 12 are arranged Within the spaces 16, they are approximately flush with the inner walls of the longitudinal sides 17 of the box-car. Means are provided to detachably lock each vertical track-section 12 within the recess or space 16, preferably embodying a spring catch 18, secured to the inner wall of the longitudinal side 17, as shown at 19.

he numeral 20 (see more particularly Figs. 2, 3 and 4), designates upper horizontal rail-sections which are rigidly secured to the top 21 of the grain car b straps 22 secured to rafters 23 sleepers 24. These horizontal track-sections 20 may be secured to the top of the box-car by any other suitable means. Thehorizon- ,tal track-sections 20 are arranged in superposed pairs, theklower pair being adapted or registration with the vertical track-sections 12 (to the right in Fig. 2), while the upper horizontal track-sections 20 are adapted for registration With the vertical track-sections 12 to the left. Each of the horizontal track-sections 20 is approximately L-shaped in cross-section, and has horizontal and' vertical flanges 25 and 26, as

more clearly show 1 n Fig. 4. Each door is formed of a plurality of door-sections or its inner side and near its ends with trans verseverticalgrooves 28, adapted to slidably receive the flanges 13 of the vertical. track-sections 12 and tln flanges 26 of the horizontal track sections 20. These doorsections or strips 27, when in their operative positions, are arranged between the posts 14 and the vertical track-sections, as shown in Fig. 5, and are adapted to slidably engage therewith to be freely raised and lowered with relation thereto. By the flanges 13 fitting within the transverse grooves 28 of the door-sections 27, the door-sections and the vertical traclcsections 12 are locked together, whereby it is impossible to swing the track-sections into the recesses or spaces 16. When the door-sections or strips 27 are moved upwardly and upon the horizontal tracks 2-0, the flanges 26 enter the transverse grooves 28, while the flanges engage the upper sides of these door elements. Corresponding ends of the horizontal track-sections Q-O are preferably closed, as shown at 29, to limit the movement of the door-sections 27 in one direction longitudinally of the horizontal lliHJlPSQCtlOllS. The movement of these door-sections in an opposite direction Hit" be temporarily prevented by means oi pii latch-hooks 30 as shown.

The operation of the ap aaratus is as follows: hen it is desired to close or partly close the door openings 11, the vertical traclosections 12 are swun to their 0 erative positions, subsequent to which the doorsections or sections are moved longitudi naliy oi the horizontal track-sections and pass from the outer ends thereof onto the upper ends of the tracks ctions 12. These door-sections then slide downv-rardly upon the track-sections l2, and assume the operative position as shown in Figs. i and it It is obvious that any suitable number of these door-sections may heal-ranged in proximity to the door opening, while the others in the same set may be stored in the upper portion of the car upon the horizontal track-see tions 20. V hen it is desired to uncover the door openings, the door-seetions 27 are moved upwardly along the vertical tracksections 12 and passed upon the horizontal track-secti us 20, whereon they are stored.

(lopies this patent may he obteined for five cents each, by addressing the Commissioner of Patents.

The vertical track-sections are then swung outwardly to occupy positions Within the re cesses or spaces 16.

It is to be understood that the formant our invention herewith shown and described are to be taken as preferred examples of the same, and that various changes'in the shape, size and arrangement of parts may be re sorted to Without departing from the sp rit of the invention or the scope of the sub joined-1 claims.

Having described the invention, what is claimed is:-

1. The combination with a structure hav ing spaced upstanding posts forming a door opening therel'ietween, of substantially vertical horizontally swinging rails formed L-- shaped in horizontal cross-section arranged adjacent :the posts, and provided at their free edges with laterally extending flanges, means to pivotally connect the corresponding opposite edges of the rails with the posts so that the rails may be swung horizontally and the flanges thereof brought to positions over-lapping the inner sides of the posts, and

. a plurality of door sections vertically movable with relation to the rails and arranged between the posts and the rails and having near their opposite ends transverse slots to receive the flanges of the rails whereby the rails are locked in the inner position while the door sections are in the closed position.

The combination with a wall of a car provided with a door opening and having substantially vertical recesses formed upon its inner side adjacent the opposite sides of the openijug; of substantially vertical horizontally swinging rails pivotally moiinted. within said recesses and adapted for move ment into and out 01 them and provided near their free edges with laterally extending flanges to be moved into proximity with the opening; and vertical door sections provided with transverse grooves to rec 'e the flanges whereby the rails are locked against lateral movement.

In testimony whereof we affix our signatures in presence of two witnesses.
