vTo @ZZ whom it may con/cern:

' Beit known that I, JOSEPH E. DRAKE, a citizen of the United States, and a resident of Blue Rapids, in the county of Marshall and State'of Kansas, have invented a new and Improved Grain-Door, of which the following is a full,

clear, and exact description.

The purpose of this invention is to construct a substantial grain-door for freight-cars, which doorvwill involve lfew parts and none readily detachable, thus making it practically impossible for the parts to be stolen, as frequently happens at obscure railway-stations. l

A further object is to construct the door so `that when moved into inactive position it will not interfere in any way with the use of the car for ordinary purposes.

This specication is an exact description of one example of my invention, while the claims define the actual scope thereof.

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

' the line 2 2 of Fig. 3 looking upward into the roof of the car and showing the grain-doors folded. IFig.' 3 is a fragmentary cross-'section showing in section one grain-door closed and in elevation the other grain-door thrown up-l ward. Fig. 4 is an enlarged elevation of the.

grain-door, and Fig. is a detail of one of the latches for holding the grain-doors raised.

Two grain-doors and their appartenant parts are provided for each car; but in this speciiication I will describe them inthe singular. The grain-door, as best shown in Fig. 4, is made up of two rigid main sections 10 and 11, held securely by a U-shaped framebar 12. Intermediate the sections 10 and 11 a transversely-slidable loading-door section la is located. This section 14 has at each end and'on its outer side battons 15, and at its middle two battons 16 are located, (sce Fig. 3,) these battons being one at each side of the door-section 14 and serving to limit the sliding movement of said section, so as to prevent'its complete detachment from the door, but enabling it to be moved toward either side, so as to leave an opening at one or the having a point 19 on its lower edge, this pointv being adapted to engage the floor of the car 'and hold the grain-door against swinging inward, as will be more fully apparent hereinafter. The door is preferably constructed of stout sheet metal and is held to move vertically over and from the opening 18 by means Yof guides 20, as shown. The U -shaped framebar 12 is best constructed of metal and has its connecting or horizontal portion 12a arranged above the npperedge of the graindoor and parallel therewith. 18a represents a spring-catchfor holding closed the doorsection 18.

The grain-dooris mounted by means of the portion 12a of the frame-bar 12in a splittube guide 21, located inside of the car and extending horizon tally along the vertical wall thereof just over the door opening. This guide 21, as illustrated best in Fig. 2, extends for a distance equal to the width of .the dooropening and thencecontinnouslyon past the door for an equal distance. Saidl guide is formed directly over the door with notches 21a, these notches extending from the split inner side of the guide downward across the bottom thereof, so as to allow the grain-door to be dropped into vertical position. The split or open side of the guide 21 is located at the inner side of the guide as contredistinguished from thebottom thereof, and consequently the grain-door can only be dropped into the vertical position when the side portions of the U-shaped frame 12 lie directly opposite the notches or openings 21a. The door `is held raised directly underthe roof of the car by means of an angular latch 22, which is carried on a rock-bar 23, and this har is tted to slide in a split-tube guide 24, similar to the guide 2l except that it is fastened to the roof inside of the car, and its split or open side is on the bottom of the guide, as contradistinguished from at the side thereof.

mately the same distance that the guide 2l extends, andat a point directly opposite the door the guide 24 isformed with a notch 24a The guide 24 extends approxiloo in its side, so as to allow the latch 22 to be rocked laterally. At all other points the sides of the guides 24 hold the latch against rocking movement; but when the point ofthe notch 24a is reached the latch may be swung back into said notch, thus clearing the graindoor and releasing it.

In the use of the invention when the door is to be folded it is raised so that the ends of the side portions of the frame 12 may move through the notches 21, and then the sliding plate 18 of the door is moved back and the latch 22 is thrown laterally, so that upon returning it may be moved into the opening 17 of the section 1l of the door, thus holding the door raised into horizontal position.

When this has been done, the entire structure, including the grain-door and the latch 22, should be slid horizontally in the guides 21 and 24, so as to move the grain-door toward one end of the car. To move the door into active position, it should be slid back to a point opposite the door-opening, the latch 22 swung laterally to disengage the door, and the door dropped, the said parts of the frame 12 moving through the notches 21a. The door may then be swung snugly against the frame of the door-opening, and by pushing down the plate 18 the spur 19 may be engaged with the Hoor of the car, thus holding the door in position, as Fig. 3 illustrates. This having been done, the car maybe filled with grain by moving the section 14 from one side to another. To empty the car, the plate 18 should be moved up by the use of a pinchbar or the like, thus uncovering the opening 17. v

It will be observed that when the two grain-doors of the car are provided they Will interfere with each other in folding unless provision is made for sliding them toward opposite ends of the car, and in Fig. 2 it will be observed that the two pairs of guides 21 and 24 extend oppositely toward the ends of the car. j

When, therefore, the doors are to be folded, one is moved up first and slid toward its proper end of the car, and then the other is moved up and slid toward the opposite end. This operation is reversed when the doors are to be moved down into position for use.

If desired, a suitable fastening 25 (see Fig. 1) may be provided to hold the door-section immovable relatively ,to the other parts of the door, and this fastening may have a lock applied thereto, if desired.

Various c hanges in the form and details of my invention may be resorted to at will without departing from the spirit of my invention. Hence I consider myself entitled to all forms of the invention as may lie Within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a railway-car, of

a grain-door,and a guide in the' form of a split tubehaving a notch extending laterally from the split side thereof, the grain-door including'a part running in the split tube and capable of moving laterally through the notch.,for the purpose specified.

2. The combination of a split tube forming a guide and having a lateral notch extending from the split portion thereof, and a member running in the split tube and having a transversely-extending portion capable of moving through .the notch, for the purpose specified.

4. The combination with a railway-car, of two split tubes forming guides, said tubes each having a laterally-disposed notch extending from the split portion thereof, a graindoor having a part running in one split tube and capable of* moving through vthe not-ch therein, and a latch for the grain-door, said llatch having a part running in the other split tube and being capable of lmoving through the notch thereof, said split tube being located directly under the roof of the car so as to hold the door folded in horizontal position adjacent to ,the roof.

5. The combination of a split tube forming a guide and having two laterally-disposed notches therein, a grain-door, and a U -shaped frame-bar, the middle portion of which runs in the split tube and the side portions of which are capable of `moving through the notches in the tube, for the purpose specified.

6. The Vcombination with a grain-door, lof a split tube forming a guide and having a lateral notch therein, and a latch comprising a latch proper and a bar slidably fitted in the split tube and having the latch joined thereto, said latch extending transversely of the bar to permit the latch to move through the notch in the guide-tube.
