GRAIN-DOOR.

Specification of Letters Patent.

Patented Feb. 4, 1919.

Application filed October 11, 1917. Serial No. 195,986.

To all whom it may concern Be it known that we, HUGO S. BRYANT and FIRM MILLER, citizens of the United States, residing atAtchison, in the county of Atchison and State of Kansas, have invented certain new and useful Improvements in Grain-Doors, of which the following is a specification.

This invention relates to grain doors and has for its principal object the production of an efficient means for supporting the door.

Another object of this invention is the production of a grain door wherein efficient means are provided for releasably retaining the door in a set position.

A still further object of this invention is the production of a grain door wherein the door is slidably mounted upon a plurality of pivotally supported hanging rods, [thus permitting the door to Slide or to swing as circumstances may require.

One practical form of construction and assembly of the present invention will be hereinafter described and is illustrated in the accompanying drawings, in which;

Figure 1 is a front elevation of a grain door constructed in accordance with the present invention;

Fig. 2 is an elevation of the inner side of the door;

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1 looking in the direction of the arrows; and

Fig.4 is a vertical line 4-4 of-Fig. 1, tion of the arrows.-

In the preferred embodiment of the present invention, about to be described, 1 designates the base beam which supports the uprights 2. The lintel beam 3 is carried upon the upper ends of the uprights 2, as shown in Fig. 2. The retaining plates 4 are positioned upon the uprights 2, the base beam 1 and the lintel beam 3 to permit the securing elements 5 to be passed through the plates 4 for firmly connecting the beam uprights and lintel beam to ether, thus forming the door frame.

rackets 6 are fixed upon the lintel beam 3 by the screws 7. The supporting bar 8 is carried by the sleeves 9 formed on the lower ends of the brackets 6. The bar 8 has heads 10, which hold the bar against longitudinal movement through the sleeves 9, although the bar may rotate when necsection taken on the looking in the direcessary. The T-joinits 11 are carried by the bar 8. The depending rods 12 are connected to the T-joints 11 and extend downwardly in parallel spaced relation with respect to each other. Since the bar 8. is rotatably supported by the sleeves 9 of the brackets 6 it is obvious the rods 12 may swing when necessary.

The door consists of a primary section 13 and an auxiliary section 14. Hinges 1 5 are secured by the elements 16 upon the primary section 13 and the auxiliary section 14 for hingedly connecting the sections together. The hollow columns 17 are positioned upon the primary section 13 of the door, and the U-bolts 18 are passed about these columns 17 and project through the primary section 13 of the door. The reinforcing plates 19 are positioned upon the outer surface of the primary section 13. The projecting ends of the U-shaped bolts 18 are passed through the plates 19 to carry the washers 20 and nuts 21 upon their projecting ends for retaining the U-bolts 18 in engagement with the primary section 13 of the grain door. As a consequence the hollow columns 17 are fixedly mounted upon the inner surface of the primary section 13. The lower ends of the columns 17 depend a slight distance below the lower edge of the primary section 13.

The rods 12 project into the upper ends of the hollow columns 17 as shown clearly in Figs. 2 and 3, thus slidably supporting the grain door. Therefore the door may be moved toward the rafter 3, although under ordinary conditions it will rest upon the base beam 1. The base beam 1 is provided with pockets 22 and the lower ends of the hollow columns 17 project into these pockets 22, when the door is in a closed position, thus preventing accidental outward movement of the grain door. If it is desired to swing the door outwardly, it will be necessary to lift the door a short distance prior to out-ward swinging movement thereof.

The uprights 2 are provided with notches 23 formed in their inner edges, as is clearly seen in Figs. 2 and 4. The sections of the grain door are provided with eyes 24, and the latches 25 are carried by the eyes 24. Bolt eyes 26 are carried by uprights 2 and nuts 27 are mounted upon the projecting ends of the bolt eyes 26 for fixedly securing these bolt eyes in the notches 23 formed in and 2. Slides 38 and 39 the uprights 2. When the two sections of the door are to be retained in a set position, the latches 25 have their free ends swung to engage the eyes 26, thereby retaining the two sections of the door in the set position. It is of course obvious that the latches 25 of the auxiliary section may be released from engagement with their respective eyes 26, thus permitting the auxiliary portion 14 to be swung to a lowered position, although the primary section will still be retained in a locked position upon the base beam 1.

The handle 28 is bolted as indicated at 29 to the .outer surface of the primary section 13 of the grain door, while the handle 30 is riveted or otherwise secured as shown at 31 to the inner surface of the primary section 13 adjacent the lower portion thereof. By the provision of these handles, which may be gripped and lifted, the grain door may be slid upwardly on the depending rods 12 or the grain door may be moved upwardly a slight distance and then swung outwardly to entirely disengage the door frame.

The uprights 2 are provided with reinforcing sheets 32 on their forward portions, as shown in Fig. 3. The primary section 13 and the auxiliary section 14 of the grain door are provided with reinforcing sheets as indicated at 13 and 14. It should be noticed however, that packings 33 are interposed within bulged portions of the sheets 13 and 14' adjacent ends of each section, as shown in Fig. 3 and these bulged portions bear upon the reinforcing sheets. Weather strips 34 are mounted upon the ends of the sections 13 and 14 and these weather strips 34 have outwardly projecting flanges 35, bearing upon the sheets 32 when the door is in a closed position, thus preventing weather from beating around the ends of the door.

The primary section 13 is provided with a pair of openings 36. Guide ways 37 are carried upon each surface of the primary section l3 and adjacent each side of the openings 36, as is clearly shown in Figs. 1

are slidably mounted upon the guide ways 37. The slides 38 are connected by the rivets 40 to the slides 39. As a consequence a pair of slides will be provided for each opening 36, thereby positively preventing the passage of weather through the openings 36 when the slides are Copies of this patent may be obtained for five cents each, by addressing the hooks 43 of the chains 42 are hooked into I engagement with the brackets 44.

Safety chains 45 are connected to the brackets 44 and have their upper ends fixedly mounted upon the brackets 46 carried by the. rafter 3. By providing these safety chains 45, the downward movement of the grain door will be limited when it is out of engagement with the base beam 1. Therefore if the door is swung slightly outwardly from engagement with the base beam 1, the safety chains 45 will prevent the hollow columns 17 from disengaging the depending rods 12.

It is of course obvious that minor changes may be made in the construction of this invention without departing from the spirit of the device, such for instance as the re-' moval of the provision of additional rein forcing and elements and for this reason it is not intended to limit the construction of this grain door to the specific construction herein shown, as it is desired to include all such forms of the invention as properly come within the scope of the device as claimed.

What we claim is:

In a device of the class described, the combination of a door frame having pockets, a door, hollow columns fixed upon said door and having theirvlower ends projecting below the lower edge of thedoor, means carried by said frame and extending into said columnsfor directing movement of the door, said columns being adapted to extend. into said pockets for holding the door in a set position, and flexible means carried by said frame and engaging the door for holding the door against displacement.

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