GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 739,149, dated September 15, 1903.

Application filed January 19,1903. Serial No. 139,547. (No model.)

To all whom it may concern:

. Be it known that I, FRANK W. CANALES, a citizen of the United States of America, and a resident of Portland, Cumberland county, State of Maine, have invented certain new and useful Improvements in Grain-Car Doors, of which the following is a specification.

My invention relates to inner doors such as are used in freight-cars for retaining grain and preventing it from pressing against the outer or regular door.

The common practice at the present time on the grain-carrying railroads is to retain the grain in the car by nailing boards across the doorway on the inside of the car, pulling off these boards when the grain reaches its destination and the car is to be emptied.

My invention relates to a door designed to take the place of these boards and to become a removable part of the car. Such doors must be able to resist the great pressure of the grain. It must be firnily held against-movementin any direction. It must be constructed 5) as to be easily'and quicklydumped. It is also desirable that no cleats or other-obstructions should be used in fastening the door in place which will obstruct the inside so rface of the car near the lower part.

My door conforms to the above conditions; and my invention consists in the various combination of parts hereinafter set forth.

I illustrate my inventionby means of the accompanying drawings, in which- Figure llis a front elevation of my door in place in the doorway of a car. Fig. 2 is an enlarged section on y y of Fig. 1. Fig. 3 is a partial elevation looking from the inside of the car and showing the upper left-hand corner of the door with the means of holding it in place. Fig. 4 is a detail section on .2 z of Fig. 1. Fig. 5 is'a detail of the angle-bar, and Fig. 6 is a detail section on was of Fig. 1. A represents the main door-frame of the car, and B is the frame of my door, which rests against the inner side of the main doorframe. The frame B consists of the top bar I) and bottom bar b with the side bars b.

The grain is heldback by a plurality of shutters pivoted to the frame, so as to be swung outward by the pressure of the grain. As here shown, these shutters are two in number, D and l), and they are pivoted horizontally, each being bolted or otherwise secured to a bar (1, having a pivoted hearing at d. The upper portion o f-the space within the frame is filled in by a panel 0. The shutters are held in place by vertical holdingbars E, pivoted at e at the upper part of the frame, and means are provided for locking.

the lower ends of these bars. As here shown, I make use of a horizontal shaft f, journaled at f below the lower ends of the bars E and provided with arms or offsets g, against which the lower ends of the bars bear when the arms are in an upright position. As here shown, the'bars are made of T-iron, and the arms 9 are bifurcated to straddle the webof the bars E, thereby preventing the latter from moving laterally.

being fastened in place by a latch h, pivoted at t". This latch is retained by the common device of a staple 'i and a pin.

The arms are held in an upright position by a lever h on the shaft, this lever It will be seen that when the pin is withdrawn the lever .is allowed to. falldown, thus releasing the arms 9 and holding-bars E and allowing the grain to run out through the shutters. Means are provided for holding the frame B against the inside of the doorframe and preventing it from being lifted up. For the purpose of holding it down I provide a vertical guide j, which is secured on the inside of the car above the frame B, the lower end of the guide being contiguous to the upper edge of the frame,uear the corner thereof,

so that the frame is held firmly down and cannot be worked 'up ward by the motion of the car or otherwise. To hold it against horizontal motion endwise or backward, I make use of an angle-bar j, which slides in the vertical guide and fits down over the corner of the frame 13. As here shown, the guidej has a longitudinal dovetail slot in which fits the dovetail projection j of the angle-bar 7. Thus the angle-barj may slide down to hold the corner and slide up to release it. The angle-bar .is held down by a key or pin m, which passes through the guide j, above the angle-bar.

The door, as will be seen, may be easily and quickly taken out and put in, and when once in placeit is secure against any strain which can be brought against it.

The door may be stored in any suitable way when not in use, but in practice I prefer to hang it by hooks against the roof of th car.

It is evident that the shutters may be one or more in number, but I prefer in practice to have two.

I claim 1. In a grain-door for cars the combination.

I of a frame, shutters pivoted horizontally on said frame, vertical holding-bars outside of said shutters pivoted at the upper portion of said frame and locking mechanism for locking the lower ends of said bars.

2. In a grain-door for cars the combination of a frame, shutters pivoted horizontally in said frame, vertical holding-bars outside of said shutters pivoted at the upper portion of the frame, a horizontal shaft below said bars, arms on said shaft against which the lower ends of the bars bear, a locking'lever secured to said shaft and a latch for holding said lever in locking position. V

3. In a grain-door for cars the combination of a frame, shutters in frame, means for retaining and releasing said shutters, a vertically-disposed angle-bar fitting over and retaining the upper corner of said frame and a vertical guide for retaining said angle-bar and permitting it to slide vertically.

4. in a grain-door for cars, the com hination of a frame, shutters in said frame, means for retaining and releasing said shutters, a vertically-disposed angle-bar fitting over and retaining the upper corner of said frame, a vertical guide for retaining said angle-bar and permitting it to slide vertically, said guide resting against the top of said frame to hold it down. v

5. In a grain-door for cars, the combination of a frame, shutters in said frame, means for retaining and releasing said shutters, 'a vertical guide having its lower end contiguous to the top of said frame to hold it down, said guide having a dovetailed slot, an angle-bar fitting over the upper corner of said frame and having a dovetailed projection fitting in said slot and a key passing through said guide above said angle-bar for holding it down.

i 6. In a grain-door for cars the combination of a frame, one or more rods pivoted horizontally in the sides of said frame and extending from one side to the other, metal plates secured to said rods to form shutters adapted to swing outward, vertical holding-bars outside of said shutters pivoted to the upper portion of the frame and means for locking the lower end of said bars.
