FALLS, IOWA.

To all whom. itmayconcem:

Be it known that I, BEVILL WALLER VVI-IrrwoRTH, a citizen ofthe United States of America, and a resident of Cedar Falls, Blackhawk county, Iowa, have invented certain new and useful Improvements in Freight-Car Grain-Doors, of which the following is a specification.

My invention relates to improvements in door-closures, and the objects of my im provements are, first, to provide a removable sectional closure for the door-casing of a freight-car or other container or housing, having. a movable section permitting a restricted opening of the closure; second, furnishing the closure with other movably connected parts to provide another opening at another location; third, to mount the closure to allow it to be bodily shifted relative to the door-casing and secured in that position,

'andotherwise to improve and modify the construction and mounting of a door as will be more specifically described in the specification, pointed out in the claims, and shown in the drawings annexed hereto, wherein Figure 1 is a front elevation of my im' proved door-closure as mounted within a door-casing; Fig. 2 is a like view thereof with the lowest section thereof swung open upwardly; Fig. 3 is a rear elevation of the structures shown in Fig. 1, and Fig. 4 is a like view showing the uppermost swinging sections dropped; Fig. 5 is a transverse section of: a building or car, showing oppositely placed doors of my construction as shifted bodily away from their casings, and detachably secured in elevated positions; Figs. 6 and 7 are enlarged edge views of my improved sectional door, with the uppermost hinged sections thereof respectively in closed and in opened positions; Fig. 8 is an edge view of the door,with the lowest section thereof elevated, and the uppermost hinged sections dropped; Fig. 9 is a perspective fragmental view of the rear of said door asclosed into its casing; Fig. 10 is a perspective view of the middle section of the door, with its depending parts, and Fig. 11 is an enlarged detail view of one of the turn-buttons for said door.

responding parts throughout the several views.

My special object in this invention is to I provide an improved construction of graindoor for freight or box-cars, but it is to be understood that my invention may be applied and used with or without any modification of its parts, as a door-closure for any other description of container or housing.

My improved closure is formed of a plurality of hingedly connected sections and suitably positioned to close the opening of a door-casing 3. The door is composed of a middle section 1 to which is hinge'dly connected a single swinging, bottom section 2 by means of double-joint hinges, and to whose upper part is hingedly connected a plurality of swingingly connected sections 4 adapted to close the upper part of the door opening. The double joint swinging connection or connections of the lowest section or flap 2 may be of any desired type, which -which has a channeled arm 14. Immediately underneath each arm-part 14 a vertical T- .bar 21 is secured to the swinging section 2,

the upper end of the web thereof having an orifice to receive a pintle 1.2 to which the lower end of the curved part 13 is pivoted. This forms a double-joint connection between said sections, and, as shown in said Fig. 8, the arm 14 may be manually lifted to both elevate and swing the section 2 relative to said middle section 1.

As best shown in said Fig. 10, the middle section 1 is provided with dependingspaced projections 32 between which said section 2 is mounted on said double iointed hinges so forwardly projecting hooked parts 16 adapted to receive removably the lower edge of the section 2. When the section 2 is closed, with its lower edge secured in the hook 16, a turnbutton 19 pivoted at 18 on the section 1 may be turned over its upper edge to secure it at that location, and other turn-buttons 15 may be-turned to engage the arm parts 14 of said hinge connection to hold the latter looked over the T-bars 21. The end edges of the middle section 1 overlie the rear face of the casing jambs 3 and are secured to said jambs, by means of turn-buttons 8 which are pivoted on said jambs. As shown in Fig. 11, each turn-button 8 as also theother turnbuttons mentioned, have projections 30 which overliethe elements which they fasten and also haveoflset oblique cam-edges 31. These cam-edges 81 engage the vertical edges of the sections or other parts which they fasten when swung downwardly, forming a tight, compressive securing means, the cam in each case preventing the abutment from becoming displaced downwardly out of engagement with the object fastened. This prevents separation of the door-parts under the jars of movement of the car.

The section 1 is reinforced on its front face by medial angles or T-bars 17, and the section 2 by medial T-bar 20. A horizontal bar 9 is secured to the rear face of thesection 1 between the end-bars 7, to partially depend therefrom to overlap the vsection 2 and thus cover and protect the joint-between said sections. The upper longitudinal edge of the section '1 is covered by a'metal strip to prevent wear. This upper edge also has h nged thereto to swing rearwardly a plurality of hingedsections 4, by means of hinges 5. These sections are narrower than the-section 1 and are, when swung upwardly lnto closed position against the jambs 3, secured thereto by means of hooks and staples 6. 1

The numeral 22 denotes a pair of guide plates having flanges secured to the rear faces of the upper parts of said jainbs opposite the ends of said sections 1, said plates having slanting guideway slots 26 toreceive therethrough the round shanks of headed or headless pins or projections 23 on the end edges of the section 1. At the lower ends of said slots are recessed squared seats 27 (see 'Fig. 5) to receive said shanks to interlock therewith to holdthe'same from moving upwardly, as shown in said Fig. 9. At'the upper end of each slot 26 is a forwardly rehooked depending clips 25, supported on rafters 24 of the car. This leaves the door opening in each-case free andunobstructed. The slot 26 in each guide 22 is made slanting in order to provideclearance for projecting parts of the door when the latter is swung to its opened position. T

The grain door shown, as mounted in a freight-car in Fig. 5, when closed, tightly seals up the door opening, and it, with its door casing, is positioned within the car relative to the ordinary car door and its casing not shown. The swinging drop sections 4 are each relatively narrow and hinged together so that oneor more of them may be dropped insidethe car to provide an opening of adesired type between the upper 1on gitudinal edge of themiddle section 1 and the top of the door casing, asmay be re quired when different kinds of grain are being transportedin the car. The opening thus provided isalso utilized as an entrance for receiving the grain in the loading of the car. opened to permit evacuation of the grain from the car through the opening thus provided, by the use of the swinging arms 14. When these arms are lifted, as shown in Fig.

8, the double-joint connection first lifts the' section 2 upwardly out of engagement with the hook 16, and then swings the section outwardly.
