Specification of Letters Patent.

Patented Feb. 23, 1915..

Application filed February 17, 1912. Serial No. 678,230.

To all whom it may concern:

Be it'known that I, EUGENE H. DAVIS, a citizen of the United States, residing at Grand Junction, in the county of Mesa and State of Colorado, have invented new and useful Improvements in Car-Doors,of which the following is a specification.

This invention relates to car doors.

The object of the invention is the provision of a simple and efficient device of this character which maybe converted from a closure into vestibule forming members between the cars while being loaded and unloaded and which may be adjusted to adapt itself to the different distances between the cars. With this type of device, stock may be loaded into one car at the side thereof and be driven through the end doors to the adjoining cars by using a platform from one car to the other, this platform preferably being adapted for arrangement within the cars so as to prevent crowding of stock against the doors.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure 1 is an end elevation. Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1 and showing the doors in open position in dotted lines. Fig. 3 is a detail perspective view of the end of the stock car showing the doors for a,double deck car, the lower ones of which are open. Fig. 4 is a detail elevation showing two cars connected together.

Referring to the drawings and more particularly to Figs. 1 and 2, 1 represents the end of a freight or stock car which is provided with a doorway or opening 2 adapted to closeby the doors 3 and 4. As shown in Fig. 2, each door is provided adjacent its top and bottom with straps 5 whichextend entirely across the door and are spaced away therefrom so as to receive the pivot or hinging rods 6 which extend from the floor 7 to the upper part of the doorway and lie parallel with the door jamb or frame 8. The door 4 has pivoted thereon a pair of locking members 9 which are adapted to engage hooks 10 carried by the door 3.

In Figs. 3 and 4, separate pairs of doors 11 and 12 are shown each hinged in a similar manner to the doors 3 and 4 and each being provided with latching levers 13, as

shown. The doors 11 are adapted to control the entrance to the lower deck while the doors 12 control the entrance to the upper deck. In Fig. 4, a platform 14 is shown extending between the cars which in Fig. 2 is shown placed inside the car across the doorway so as to prevent the stock from crowding against the doors. When a plurality of cars are arranged, as shown in Fig. 4, the stock may be driven into the side of one car and from there into the other cars through the vestibules formed by the doors. In this manner, it will be seen that each car does not have to be loaded separately and considerable time and trouble can be saved. Furthermore, if found to be necessary, the separate cars may be left connected in this manner during travel as the doors will adjust themselves readily to the distance between the cars, as before described. The platform can be held in position in any suitable manner. When the cars are arranged, as shown in Fig. 4, the free edge of each door is held to the free edge of the opposite door on the adjoining car by means of the locking member 9 and hooks 10.

hat is claimed is In combination, two cars, said cars being spaced apart, a platform adapted to extend between said cars and connect the floors thereof at the entrancepoint to said cars, means for sustaining said platform in position, two vertically disposed doors, a vertically disposed rod secured'inthe doorway of each of said cars, an upper and lower metal strap secured in spaced relation so as to provide a guideway, upon each door, said strap adapted with said doors to straddle one of said pair of rods, whereby to be hingedly mounted thereupon in slidable relation, said doors being slidable into said cars and adapted to be extended forwardly thereof to have their edges arranged in con- 100 tacting relation, means for holding said In testimony whereof I aflix my signadoors 1n extended. posltlon, each of sa1d ture 1n presence of tWo wltnesses.

doors being guided in slidable movement be- EUGENE H. DAVIS. tween the edges of said platform and the Witnesses:

to move rectilinearly in said cars. A. S. JOHNSON.
