CLOSURE FOR GRAlN-RECEPTAOLES.

SPECIFICATION forming part of Letters Patent N0. 755,859, dated March 29, 1904.

Application filed January 15, 1903. Serial No. 139,236. (No model.)

T0 at whom, it may concern:

Be it known that I, ALBERT L. ELIEL, of Parlin, Middlesex county, New Jersey, have invented certain new and useful Improvements in Closures for Grain-Receptacles, of which the following is a full, clear, and exact description.

This invention relates to a closure for bins or cars that are adapted to hold grain or similar material, and particularly to closures that are adapted to be slid up out of the way in order to permit the exit of the material inclosed.

The invention further refers to a closure of the class specified that has ameans for relieving the pressure on the door or closure, so that the act of opening the same is easier.

The invention refers more particularly to a specific form of relief in the shape of smaller openings provided with doors placed conveniently in the main door and to be opened previous to the opening of the main door.

The invention is also designed to provide a door of the class described that can be easily placed out of the way and manipulated with considerable freedom and ease.

Reference is to be had to the accompanying drawings, forming part of this specification,

in which similar figures of reference refer to similar parts throughout the several views.

Figure 1 is a view of a door provided with my new relieving means, and Fig. 2 is a horizontal section on line 2 2 in Fig. 1. Fig. 3 is a front elevation on a new door to be hereinafter described, and Fig. 4 is a central vertical section of the same, and Fig. 5 is a partial section on the line 5 5 in Fig. 3.

In'Fig. 1 I show a door 10 in dotted outline, which represents a closing-door for bins of grain or grain-cars. This door 10 is adapted to rest on the bottom of the car 11, and as now made these doors are adapted to slide up and out of the way to allow the grain to flow out. The grain in transportation settles and,

coupled with its weight, usually forces the door in its bearings so tightly that it is impossible to raise the same, and in most cases the operator is compelled to destroy or damage the door in order to effect an opening. In my construction of a door I provide an opening or openings which can be provided with a door 12, fitting snugly therein. In Fig. 1 I show two means of securing these smaller doors 12. These smaller doors are hung by means of hinges 13 and can be looked as in one case by a pivoted bar 14:, which is adapted to lock behind the clips 15, and can be securely tightened by means of a suitable cam device 1 1, or, as shown in the right-hand side of Fig. 1, the door 12 can be provided with a socket 16, placed in line with a similar socket 17 on the car-floor, and a pin 18 can be slid down to tighten the door. It will thus be seen that when it is desired to raise the door 10 the smaller doors 12, which are comparatively easy of operation, can be opened, which allows the grain immediately adjacent to the door 10 to flow out through these smaller openings, thereby relieving the pressure behind the main door, when it can be slid up out of the way and the emptying of the car completed in a short time. In Fig. 5 I illustrate a door 20,

made on this principle, having the side ears 20 and it has in turn the smaller relievingdoors 21, hinged at 22, which can be secured by means of the latches 23, or any other suitable device can be employed. Secured to the cars 20 are cords or ropes 24, running over the pulleys 29 and supporting the counterweights 25. These counterweights can be boxed in, if desired. Running through perforations in the ears 20* are the chains 26, supported at convenient points at the top and bottom, as at 27. In this way a door is provided the raising of which is facilitated by the opening of the doors 21, as described above for the doors 12, when it is desired to raise the main door 20. It can be started, if necessary, by means of a bar placed under a clip 30; but if this is not necessary the door can be slid up by hand, the counterweights 25 making this comparatively easy and the chains 27 running through the openings in the ears 20. When the door has reached the top, it can be tilted, as shown in outlines in Fig. 4:, and the bottom end of it swings upward and inward to engage a latch 28, which holds it in its raised position,

the chain 26 assuming the position shown at 26, enough slack being provided therein to allow of the twisting shown. This door being made, preferably, of corrugated iron or steel makes a comparatively light and strong door, with the flexible means of support that allows of its being easily and compactly placed in its raised position.

It will thus be seen that I have devised a door provided with a relieving means that will very much facilitate the unloading of grain from receptacles adapted for its storage.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a closure for grain-receptacles comprising a door adapted to bemoved vertically and having ears attached to its opposed upper ends, and slack chains secured at their ends and adapted to pass through the ears on the H door when the door is moved vertically, said chains acting to support one end of the door when the door is swung to an approximately horizontal position by the binding and tightening of the chains due thereto.

2. In a closure for grain-receptacles, comprising a door adapted to be moved vertically and having ears attached to its opposed upper ends, slack chains secured at their ends and arranged to pass through the ears on the door, counterweights secured to the door, said chains acting to support the upper end of the door when the door is swung to an approximately horizontal position by the binding and tightening of the chains due thereto, and means for securing the door in its approximately horizontal position.

3. In a closure for grain-receptacles, comprising a main door, smaller doors arranged in the main door, ears on the opposed upper ends of the doors, slack chains secured at their ends and arranged to pass through the ears when the door is moved vertically, said chains acting as a pivot when the door is swung to an approximately horizontal position, and supporting the door when it is swung by the tightening of the chain, and means for supporting the free end of the door in its approximately horizontal position.

' 4. In a closure for grain-receptacles, a main door, smaller doors arranged in said main door, the smaller doors each being provided with a pivoted bar arranged to rotate parallel with said smaller door and tvengage clips attached to said main door when said smaller door is closed, and a cam device situated in the center of said pivoted bar, and adapted to lock said pivoted bar against rotation.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALBERT L. ELIEL.
