JOHN RILEY, OF MINNEAPOLIS, MINNESOTA.

GRAIN-DOOR FOR FREIGHT-CARS.

SPECIFICATION forming part of Letters Patent No. 719,875, dated February 3, 1903.

Application filed .l'uly 18, 1902.

To aZZ whom it may concern:

Be it known that 1, JOHN RILEY, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Grain-Doors for Freight-Oars; of which the following is a specification.

My invention relates to devices for use in connection with box freight-cars when loaded with grain; and the object of the invention is to provide a door of simple but strong and durable construction and one that can be easily handled and will form when closed a grain-tight joint with the sides of the dooropening.

A further object is to provide a grain-door that is particularly adapted for cars containing flax or other small grains.

A further object is to provide a door which when not in use is raised and moved to an inoperative position against the side of the car, where it isout of the way when it is desired to load the car with merchandise and where it cannot accidentally become loosened from its support and cause injury to the workmen in the car.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 represents a partial longitudinal vertical section of a freight-car, showing the inside of the car and one side opening with my invention applied thereto. Fig. 2 is a vertical transverse section of one side of the car, showing the door closed. Fig. 3 is a similar view showing the door open or raised. Figs. 4 and 5 are details of the locking mechanism provided on each side of the door. Fig. 6 is a detail showing the door in its raised position and unlocked. Figs. 7 and 8 are details of a modified form of the door.

In the drawings, 2 represents the side of the car; 3, the floor; 4, the roof, and 5 the doorposts provided upon each side of the opening in the car.

6 represents a track supported by brackets Serial No. 116,021. (No model.)

7 on the side of the car above the door-opening, and being similar to the track usually provided on the outside of-the car I make no claim, broadly, to the same herein.

8 represents guide-bars provided upon each side of the door-opening and secured at the top by bolts or other suitable means to a timber 9 and near the bottom provided with fastening devices, such as bolts 10, which firmly securethe guidesto the door-posts.

The door which I prefer to employ is shown in Fig. 6 in detail and consists of a series of bars 11, preferably of wood, arranged at intervals and provided with' an outer covering of corrugated sheet metal 12, the surfaces of the bars being grooved or ribbed to coincide with the corrugations of the covering. The covering is secured to the bars by rivets or bolts, and at the ends of the door I provide vertical channel-bars 13, which receive the ends of the bars and the edges of the corrugated covering and protect them against injury and also brace and strengthen the door and cause it to slide easily in the guideways. At the top of the door, near the ends thereof, I provide castings 14, having outwardlyturned flanges or brackets 15, provided with holes to receive pins 16, that are provided on their outer ends with hooks 17. The pins turn freely in their bearings, and secured thereon between the brackets 15 are hooks or hangers 18, that swing with the pins and when the dooris raised are adapted to hook over the track 6 and support the door, While permitting it to be moved back and forth on the track.

Upon each door-post 5, opposite the point where the pins 16 will be located when the door is closed, I provide plates 19, fitting within recesses in the door-posts and projecting'beyond the edges of notches or recesses 20, also provided in said posts. These notches are adapted to receive the hooked ends of the pins 16 and when the pins are swungaround to their locked position draw the sides of the door snugly against the door-posts and form agrain-tightjoint therewith, aided, ofcourse, by the pressure of the grain inthe car, which will tend to force the door out and seat it firmly against the posts. If preferred, addi- IOC tional locking devices may be employed besides those at the top of the door; butI do not consider that any locking means will be necessary at the bottom, as the pressure of the grain will be sufficient to hold the door firmly to its seat. The guide 8 on that side of the opening toward which the door is moved when raised I provide with an offset 21, which when the door is raised and supported on the track allows the castings 141: and the, locking devices and hooks carried thereby to be moved past the guides to the position indicated by dotted lines in Fig. 1, where the door is hung against the side of the car. I prefer to provide lugs 22 on the castings 14:, projecting in toward the hooks 18, and by slipping the pins 16 in their bearings in either direction the hangers 18 will pass behind these lugs, and when the door is raised and the hangers disengaged from the track they will be prevented from swinging down to the position shown in full lines in Fig. 1 and the pins 16 will be prevented from turning in their bearings until the door is in its closed position and the operator desires to lock it, when the pins are moved lengthwise to move the hangers 18 out of engagement with the lugs 22 and allow the hooks 17 to swing into engagement with the plates 19.

In Figs. 7 and 8 I have shown a door of modified construction, which consists in pro viding castings 23 at each end of the door and having lugs 24:, whereon bars 25, preferably of wood, are secured by any suitable means. The surfaces of the bars and of the castings are corrugated, as shown, to coincide with the corrugated sheet-metal covering, corresponding to that heretofore described, that is secured to the bars and castings by rivets or bolts. In this form of door the channel-iron end bars are dispensed with, the castings having flat outer faces which bear upon the door-posts and form close-fitting grain-tight joints therewith.

To adapt the door (either the form shown in Fig. 6 or in Figs. 7 and 8) for use with cars loaded with small grain, such as flax, I prefer to provide straps 26, secured to the doorposts near the bottom of the door, and provide vertical grooves 27 in the castings 23, that are adapted to receive the straps 26 and positively prohibit any leakage of the small seeds around the bottom of the door.

I have shown a door of a combined wood and iron construction, but do not wish to confine myself thereto, as one entirely of wood may in some instances be preferred, and in some cases a door entirely of metal may be desired, and hence I do not desire to be confined to the materials employed or to the details of construction.

I have shown my invention applied to the door-openings in the sides of a car; but it will be understood that it may be used in the ends of the car as well.

I claim as my invention 1. The combination, with a freight-car, of a track secured over the opening in the side of the car, a door, hangers provided thereon and adapted to rest and slide upon said track, locking devices provided in connection with said hangers, guides for said door, and an offset provided in one ofsaid guides near said track, for the purpose specified.
