GEORGE M. BOLL, OF MOUNT HOPE, KANSAS.

GRAIN-BIN.

Specification of Letters Patent.

Application filed September 22, 1908. Serial No. 454,197.

To all whom it may concern: I

Be it known that I, Gnonon M. Born, a citizenof the United States, residing at Mount Hope, in the county of Sedgwick and State of Kansas, have invented certain new 3' and useful Improvements in Grain-Bins; and I do herebydeclare the following to be I a full, clear, and exact description of the invention, such as Will enable others skilled in the art 1 which it appertain's to make and use the same.

My invention relates to granaries or bins for the storage of grain and particularly to the grain is removed.

It. has for its object to provide additional protection against theft and to preserve the grain in the. vicinity of the door against moisture and fire.

Another object is to strengthen the wall of the bin to oifsetthe weakening caused by cutting away a part thereof to form the door way.

The invention also conten'iplates the con-. struction of the door in such a manner and of such size as to permit of the passage of persons therethrough whereby the bin n'iay be used for other purposes when grain is not stored therein.

The invention consists of a double doo'r, the-outer one being constructed of heavy material and hinged to swing outwardly while the inner door is composed of sliding sections which are separably removable.- Adjustable truss bars are placed across the doorway between the inner and outer doors.

The invention also consists in the features of cm 'truetion and combinations of devices hereiii' ifter described and specified in the claims.

in the acrannpanying drawing illustrating the preferred embodiment of my invention: Figure l is an elevation of a circular metal bin provided with a door constructed in accordance with my invention. Fig. 2 is a broken elevation showing the door on an cnlargcd scale. the outer door being open. Fig. 2") is a broken elevation of a portion of the intcrior of the bin showing the slides holding the sections of the inner door. Fig

'l is a i i vertical sectional view on the line a of i Fig. 1. and Fig. 5 is a horizontal sectional view on the line l/ I/ of Fig. 'l. Referring more particularly to the draw- 5 mg,

the granary or bin 1 is consirncicll of i sheet metal in any suitable manner. doorway or opening is cut in the walls of the bin of sufficient height and width to permit persons to pass therethrough. Around the outer edge of said doorway there is secured a projecting frame 3 con'iposed of angle irons riveted to the walls. Portions of the top and bottom angle irons are extended to one side to form hinge-lugs l. The outer door 5 is constructed of a sheet metal plate (3 around the edges of which are riveted iiiwardly extending angle irons 7. The top and bottom angle irons on the door are ex.- t'cnded on one side to form other hinge-lugs b which are secured to the lugs -'t of the door frame by pivot pins 5). The angleirons of the door are adapted to fit outside of the angle irons ot the door frame. The angle iron on the side ot'the door next to the hingelugs is. cut away, as at 10, adjacent to said lugs to tit over the hinge-lugs the door frame when the door is closed. The door should it the frame closely so as to be as near air tight as possible and prevent the entrance of moisture or lire. Anysuitable locking device may be employed for securing the door.

The sliding sections 11 composing the inner door are arranged in vertical channelpieces [2 which are prel'erably riveted to the sides of the inner door frame. comprising angle irons 13 which are in turn riveted to the inner edge of the dooiwvay. Said angle irons are secured by the same rivets which fasten the angle irons composing the outer door frame. A portion of each channelpiece at the top of the doorway is cut away, as at 1%, to permit the-upper section to be removed inwardly. After the upper section is removed each of the other sections may be raised and taken out in turn through said out out portions. The upper section is retained in place by havingits upper edge engage a groove in a channel or U-shaped iron 'l5 which is; constructed similarly to the lower parts oi? the channel-pieces and is fastened to the top angle iron of the inner door frame. The lower edge of the upper section is provided with a pivoted latch 16 adapted to be turned down outside of the ltiXl'. lower section. When it is desired to l'tlllUYt said upper scction, the latch released whereupon the lower edge of said sec 1 tion may be pushed inward and its upper edge a l'tcrward removed from the groove in the top channel iron to. 'lhowall ol' the bin is strengthenedwhere Patented tlcpt. 7, 1909. 7

. opposite parts'thereof to outer door frame and the doorway is cut by adjustable truss rods 17 which may. be placed at the desired distancejapart. Each of said truss rods comprisestwo parts 18 which are hin ed to the opposite edges of the doorway and are connected by a turnbuckle 19. Said truss rods are arranged between the inner and outer doors, the hinged parts being connected to loops or staples 20 which are passed through and secured to the projecting portions of the angle irons forming the inner and outer door frame. \Vhen the bin is partially or entirely emptied, the truss rods may be disconnected at the turnbuckle, allowing the fall down and hang ong the edges of the doorway as illustrated in dotted lines in Fig. 2.

I claim: i r

The combination, with the wall of a grain 'bin having'a doorway therein,'of an an inner door frame projecting respectively from the outer and I inner faces of said wall, a flanged outer door adapted to close around the outer frame, said inner door frame being provided with groovesat its sides, and a plurality of removable door sections arranged in said grooves.-

2. The combination, with the wall of a grain bin having a doorway therein, of an outer door frame and an inner door'frame both comprising angle irons secured by the same rivets to the outer and inner edges of said doorway, an outer door adapted to close upon the outer frame, to the lateral edges of the inner frame, and

channel-pieces,
