GRAIN-DOOR.

SPECIFICATION forming part of Letters Patent N0. 778,946, dated January 3, 1905.

Application filed June 10, 1904. Serial No. 211,946.

To aZZ whom it may concern:

Be it known that we, ULYSSES M. BOGARD and ALBERT L. MAPLE, citizens of the United States, residing at Glasford, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Grain- Doors; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to doors for grain-cars, and relates particularly to the supporting and fastening devices therefor.

The invention has for its object a car-door which is made in two sections for the purpose of increasing the length of the door as the car is filled with grain and the same have a telescopic relation with swingably-supported hangers for raising said doors out of position.

The invention consists, further, in the support for a car-door which comprises a rod journaledin suitable bearings attached to the body. of the car, which is provided with depending integral rod portions which have a telescopic relation with tubular members attached to the face of the grain-door, of a pair of coil-springs wound around the first-mentioned rod, one end of said spring fixed in the woodwork of the car, and the opposite end bearing against the outer face of the depending rods for the purpose of assisting in raising the car-door and to also prevent lateral displacement of the depending hangers, also the the grain-door during any sudden jar or motion of the car. Y

The invention consists of certain other details of construction to be more specifically set out in the specification and illustrated in the accompanying drawings, in which Figure 1 is an inside elevation of a car-door and the mechanism for supporting and raising such door. Fig. 2 is a vertical section taken on the line a a of Fig. 1. Fig. 3 is asectional detail to show the door as it appears when raised and locked in position against the roof of the car. Fig. 4 is a detail in front elevation,showing the manner of locking the graindoor to the body of the car.

Like numerals of reference indicate corresponding parts throughout the figures.

1 denotes the body of the car, only a portion of its flooring, the side sills for the door,

and a longitudinal sill of its roof being shown, and is deemed sufiicient to illustrate the application of our invention thereto. The dooropening of the car is indicated as 2 and the main section of the grain-door as 3, which is of a suitable height and is of sufficient width to extend across the door-opening 2 and have a bearing against the inner face of the posts or sills forming the side framework of said opening. When the door 3 is in the position shown in Figs. 1 and 2, we have provided for rigidly fixing or locking the same in such a position. This we accomplish through the pivoted latch 4:, which has a short stud 5, adapted to engage and be forced into an opening in the side sills or posts of the door-opening. Thus to remove the door 3 either by raising or swinging the same it will first be necessary to swing the latch 4 and release the stud 5, when the door may be moved to some other desirable position.

6 denotes a longitudinally-carried rod adapted to lie parallel with and adjacent to one of the longitudinal beams forming the roof of the car, and said rod is journaled in the boxing 7, suitably attached to said beam, and 8 indicates a pair of depending rods which are integral with the rod 6, and the body of said rods have a telescopic relation with tubes 9,attached to the front face of the door 3, said rods when the door is in its lowermost position extending into the tubes 9 to give the same a bearing or a purchase to adapt the raising of the door in the manner to be described.

10 denotes a second section of the door 3, and is hung upon the rods 8 by means of the angular plates 11, which are attached to the body of the section 10 and are provided with an elongated slot, (not shown,) through which the rods 8 pass. In the position shown in Fig. 1 the sections of the door are in their lowermost position and of a convenient height for shoveling grain into the car. As the grain reaches the height of the door, as is now shown, the section 10 is elevated on the rods 8 until its lower 13 denotes a pair of coil-springs of the proper tension, which are carried on the rod 6, one end fixed to the body of the car, as at 14, and their opposite ends dropped down and having angular extensions 15 bearing or exerting pressure against the outer faces of the'extreme upper portions of the rods 8. These springs serve a double purpose: first, they assist the operator when swinging the door inwardly and upwardly out of position; secondly, the fixing of the springs in the body of the car prevents any lateral movement of the rod 6 and also any displacement of the door by reason of any jar or movement of the car.

To raise the door out of position to permit of the removal or discharge of the grain contained in the car, the door may be raised by inserting a bar beneath the cleat 16, attached to the lower outer face of the section of the door 3 when the operator may raise the door in a vertical line,permitting the tubes 9 of said door to telescope over the rods 8, and when the door reaches its extreme upper position the plates 11 will engage with a bowed portion 17 of the rods 8, andacatch 18, which has a hinged joint with the body of the door, is caused to engage with the rod 6 and serves as a hanger for the forward end of the door when in such raised position, (see Fig. 3,) and the lower or what may be termed the rear end of the door when in such raised position may be held so elevated by some suitable catch, (not shown,) attached to the roof of the car.

We are aware that a grain-car door is not new and that to elevatesuch a door on rods and to swing the same out of position is not new; but we do not know of a car-door which.

is made in two sections for the purposes herein, which have a telescopic relation with hangers which are integral with a swingably-supported rod, nor are we aware of the use of coil-springs serving to assist in elevating the door and the further purpose of preventing lateral displacement, nor to the particular form of latch for locking the lower section of the door when in its lowermost position.

It is obvious that the details ofconstruction may be modified and equivalents resorted to without affecting the principle and scope of the invention.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent of the United States, is

1. In a device of the class described,the combination of a grain-door made in two sections, a pivotally-mounted rod having integral depending portions telescopically connected with the door, and coil-springs on the pivoted rod, adapted to prevent longitudinal movement of the rod in its supporting-journals, substantially as specified.

. 2. In a device of the class described,the combination of a grain-door made in two sections, a pivotally-mounted rod having integral depending rods, tubes on the outer face of one section of the door with which the depending rods have a telescopic relation, angular plates on the other section by means of which said section is hung on the rods, and coil-springs on the pivoted rod, with one end of the springs fast in a support and the opposite end exerting pressure upon the depending rods, substantially as specified.

3. In a device of the class described,the combination of a grain-door made in two sections, a rod, with integral depending portions, pivotally connected with the door-frame, springs to prevent longitudinal movement of the rod and assist in swinging the door to a horizontal position, tubes on the lower section of the grain-door with which the depending rods have a telescopic relation, the upper section slidably arranged on the depending rods by angle plates, said section adapted to drop down against the inner face of the lower section, levers with studs thereon engaging the framework of the door to lock said door in position, substantially as described.

4. In adevice of the class described,the combination of a grain-door made in two sections, tubes on the lower section with which depending rods on a pivoted rod have a telescopic connection, springs on said pivoted rod to prevent longitudinal movement of said rod and assist in swinging the door to a horizontal position, angular plates with eye-holes engaging the depending rods, on the upper section, levers with studs thereon on the lower section and hooks on the door-frame engaging the upper section when raised to lock the grain-door in position, a cleat on the lower section to aid in prying the door up, a hook to lock the door in its telescoped condition to the pivoted rod and a suitable hook to lock the door in its telescoped condition in a horizontal position to thel ceiling of the car, substantially as specifiec In testimony whereof we affix our signatures in presence of two witnesses.
