Specification of Letters Patent.

Application filed April 28, 1909. Serial No. 492,653.

To all whom it may concern:

Be it known that I, EDGAR B. GILLELAND, citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in GrainDoors, of which the following is a specification.

This invention comprehends certain new and useful improvements in grain doors for freight cars, and the primary object of the invention is a door of this character that may be manufactured at a relatively low cost, and the parts easily assembled, which will be durable in construction and withstand the pressure of the grain, and the hard usage to which doors of this character are subjected, and which at the same time will be light and easy to handle.

With these and other objects in View as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure 1 is an outside face view of a grain door constructed in accordance with my invention; Fig. 2 is a vertical longitudinal sectional View, the door being shown in closed position in full lines, and in folded and raised position in dotted lines; Fig. 3 is a detail perspective view on an enlarged scale of the relief door or panel; Fig. 4 is a similar view of the upper section of the main door; Fig. 5 is a horizontal sectional view on the line 5 5 of Fig. 1; Fig. 6 is a perspective view of the lower section of the main door; Fig. 7 is a partial sectional and top plan view, the section being taken approximately on the line 7-7 of Fig. 1; and, Fig..8 is a sectional perspective View of the lower corner of the main door, illustrating details which will be hereinafter specifically described.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring to the drawings the reference letter A designates my improved grain door which is preferably constructed in upper and lower sections 1 and 2 both of which are formed of relatively light sheet steel or similar metal, the section 1 being relatively smaller as shown and the two sections being hinged together, along their horizontally disposed abutting edges by partially countersunk hinge members 3, the lower section 2 being thereby arranged to be swung inwardly and upwardly so as to be folded upon the upper section 1.

In the present embodiment of the invention the upper section 1 of the door is provided near its upper corners with brackets 4 that are designed to receive vertically eX- tending rods 5, the lower ends of said rods 5 being connected together by a cross rod to form a substantially U-shaped frame, and the upper ends of the rods 5 being pivotally connected to staples 7 that are bolted or otherwise secured to the top cross beam 8 of the door frame or casing. It is to be noted that the straps or brackets 4 are of an interior length greater than the diameter of the rods 5 so as to permit of a sidewise movement of the door in the direction in the length thereof, for a purpose that will be hereinafter pointed out.

As above stated, one of the objects of my invention is to produce a door which will be strong and yet light. To this end, both sections of the door are formed with longitudinally extending corrugations 9, the lower section 2 is provided with battens 10 preferably of angle-iron or steel riveted thereto, the side edges of both sections are curled upon themselves as indicated at 11, and the upper and lower edges of both sections are trussed as indicated at 12, the truss formation being formed of a plurality of major portion of the'stress is directly imposed upon the .side edgesof the. door beyond the vertical stiles or jambs.

Y 15 designates the relief door or panel. This is also preferably constructed of sheet Steel having a portion bent inwardly at its upper edge as indicated at 16 to form a handle by which it may be pried open.V The side edges of the panel 15 are bent laterally as indicated at 17 to form flanges which .fit within preferably angle-metal flanges 18 riveted to the two middle battens so as to formdoor guides or channels as best illustrated ,in Fig. 5. The lower edge of the relief panel is bent inwardly and downwardly as indicated at 18 so as to fit closely Y' over the returned lower edge of the lower section 2, this construction preventing any leakage of thegrain at* this point, and being adapted to, engage with the upper edge of the relief opening so as to retain the re- ,lifef panel or door within its guides or channels and to prevent the panel from being lifted entirely out when opening the same to permit the unloading of the grain..

In order to holdthe door in a raised or inoperative position, I have, in the present embodiment of my invention, turned the upper ends of the rods 5 outwardly, where they engage the staples 7, thence down- K wardly, inwardly and upwardly to form tion illustrated two upwardly facing hooks; and I have cut out the returned lower edge of the lower door section 2 near the corners thereof as indicated at 20 so as to form openings to receive the hooks-.19` so that the latter may engage ianges 21 constituted by the remaining portions of the returned lower edge. If

desired, the metal defining the sides of the openings 20 may be-entirely sheared off or bent inwardly or outwardly and riveted as indicated at 22.

p It will be understood that in the operation of opening the door, the lower section, 2 is moved inwardly and upwardly so as to fold upon the upper section 1, the latter moving downwardly on the rods 5 in this movement until the straps or brackets 4 engage with the connecting rod 6 at the lower ends of the rods 5. When the lower section 2 has been folded up against the upper section 1, the door may be raised iirst at one corner and then at the neXt so as to cause the flanges 21 to engage over the hooks 19 and hold the two sections securely vfolded one p upon the other, and the entire door is then swung inwardly and upwardly to the posiin dotted lines in Fig. 2, the door being slid along the rods 5 and the cross rod 6 being engaged with a carline r hook 23. By the provision of the relatively large retaining straps or brackets 4, the door may be slightly tilted to effect the engagement of the flanges 22 with the suspension hooks 19, thereby avoiding the il'cessity of the operator lifting the entire weight of the door at one time. l .I

From the foregoing descriptionl in connection with the accompanying drawing, it is manifest that I have provided a very simple, durable and eflicient construction of grain door which can be easily applied to a car of any height, either common, standard, or special, without the necessity of any changes in the construction of the car itself or of the door.

Preferably the lower section 2 of the main door is provided with a strip 24 secured thereto by counter-sunk rivets at the upper edge of t-he relief opening so as to prevent the leakage of grain at this point.

Having thus described the what is claimed as new is:

1. In a grain door, suspension rods, supports with which said rods are connected for a laterally swinging movement, a door constructed in upper and lower sections hinged together at their meeting edges, the upper section being slidably mounted upon said rods, means for connecting the lower section of the door to said rods with such section folded upon the upper section, and means for holding said rods and the door in folded condition in an elevated positiony underneath the roof of a car.

2. In a grain door, suspension rods, supports with which said rods are connected at one end and on which they are arranged to swing laterally, a door constructed in upper and lower sections, the upper section having a sliding connection with the rods, and the lower section being hinfed to the upper section, the lower section being provided at its lower edge with anges, and the rods being provided at their upper ends with upwardly facing hooks designed to engage said flanges.

3. A grain door,

invention,

comprising suspension from each other and thence downwardly and inwardly and upwardly to form upwardly facing hooks, supports with which such ends are plvotally connected for a lateral swinging movement of the rods, a connecting rod connecting the rst named rods at one end of the latter, a door embodying an upper section, brackets secured to said upper section and extending over said first named rods and of an interior length greater. than the diameter of said rods, and a lower section hinged to the upper section and provided at its lower edge with flanges designed to engage said hooks.

4. A grain door having its lower edge returned upon itself to form a support, the returned portions being partially cut away to form openings, leaving a portion remaining to form lianges defining a wall of said openings, suspension rods for holding said door in an elevated position, and brackets secured to the door and having a Vertical sliding connection with the rods, the rods being provided with hooks to engage said flanges and the door being constructed in upper and lower sections hingedly connected together, the flanges being formed on the lower section and the brackets being se-
