GRAIN-Doon.

Speccaton of Letters Patent.

Patented April 8, 1906.

Application filed May 12,1904, Serial No. 207,565.

signed particularly for freight-cars; and the object of my invention is to provide a door` of simple but strong and durable construction and one that will be comparatively inexpensive to manufacture and place on a car and can be easily operated to close the car or obtain access thereto.

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.

ln the accompanying` drawings, forming.

against the side of the car when it is raised.

Fig. 6 is a vertical longitudinal section of a oar, showing a modified construction of the device for supporting the door thereon. Fig. 7 is a detail of one of the door-supporting rods or hangers. Fig. 8 is a similar view y showing the rod swung to another position.

Fig. 9 is a section on the line x of. Fig. 8. Fig. 10 is a section on the line 2 z of Fig. 8.

In the drawings, 2 represents a freight-car of ordinary construction, having the usual door-posts 3 and rafters 4. A rod 5 is secured on the top of the car above the door upon suitable brackets 6, and rods are slidably mounted on said rod 5 and have hooked lower ends 8. The door 9 is provided with castings 10 and 11 to receive the rods 7 and slide freely up and down thereon to allow the door to be raised to the top of the car or drop to the bottom thereof to close the door.

Suitable guides 12 vare provided on the door-casing, and a relief-door 13 is arranged near the bottom of the doorV 9. A bar 14, having an inclined or beveled surface, is provided on the door 9, and beneath said bar are castings 15, which when the door is raised slide past the hooks 8 and engage the same and `support the door when it is lowered. The rods 7 have sufficient play in the castings 10 and 11 to allow the bar 14 to press the hooks 8 out of the path of the castings 15, and when the castings have been lifted above said hooks the operator can press the rods into their normal position, where the hooks will engage the castings and support'the door when it is lowered. v

Opposite the door-opening between two of the rafters l provide a rod 16, having an offset 17 near one end and carrying a hook 18, that is freely slidable on said rod from end to end thereof. A casting 19 is secured to the bottom of the door and provided with a link 20, that is adapted to engage the hook 18 when the door is lifted and swung up to a horizontal position under the roof of the car.

rThe track supporting the door extends a considerable distance beyond the door-opening on one side, as indicated in Figs. 1 and 6, to allow the door to be moved away from the opening. When the door is moved along the track-rails away from the opening, it may be secured against the side of the car by hooks 21, engaging the castings 11, and whenever desired the door may be swung up under the car-roof and supported by the rod 16. At such times the offset in said rod will prevent the supporting-hook 18 from slipping on the rod and allowing the door to interfere with the corresponding door on the other side of the car.

In Fig. 6, 'l have shown a slight modification in the construction of the door, which consists in providing hangers 22, slidable on the rod 5 and wherein the rods 7 are swiveled instead of being integral, as shown in Fig. 1. Lugs 23 are provided on the rods 7, that are adapted to enter slots 24 in castings 25 on the upper door-section 26, which rests upon the lower section and may be raised simultaneously therewith or independently thereof, as preferred.

If it is desired to spout grain into the car, it will be found quite convenient to raise this upper door-section and insert the spout between it and the lower section. The lugs in the slots 7 will normally register with the slots in the castings 25 when the door-section is raised, and when the castings have passed the lugs the operator grasping the lower ends of the rods 7 can turn them in their supports IOO and move the lugs away from the slots 24, so that the door-section will be held in its raised position. The other' parts of the door are substantially the same as shown in Figs. 1 and 3.

I claim as my inventionA- l. The combination, with a car, of a track suspended over the door-opening and extending along the side ofthe car beyond said opening and provided with sliding hangers 22, rods 7 swiveled in said hangers at their upper ends and having their lower ends inwardly turned forming hooks 8, a door 9 having guides for said rods, and stops to engage said hooks S when the door is raised, substantially as described.

2. The combination, with a car, of a track mounted thereon, a door slidably supported on said track and arranged to be swung inwardly thereon to a position beneath the roof of the car, a rod having an offset supported beneath said roof, a hook slidably arranged on said rod, and a link carried by said door and arranged to be engaged by said hook when the door is lifted.

3. The combination, with a car, of a track mounted thereon over the door-opening, hangers slidably arranged on said track, rods swiveled in said hangers and provided with lugs near the upper ends, a door composed of two sections slidably mounted cnrsaid rods, the upper section having guides provided with slots to receive said lugs and allow said upper section to be moved to the upper ends of said rods, Jfor the purpose specified.

In witness whereof I have hereunto set my hand this 5th day of May, 1904.

JOHN RILEY.

In presence ot RICHARD PAUL, M. HAGERTY.
