The edges of the end of the door to which it is attached inward doorway and door not only conform in shape on a plane with the opposite edge of the door or to each other, but also they are preferably flush with the side of the car. Thus by the 5o beveled orinclined, as shown, in orderto make use of a single track at the top and the two roo hangers, one rigid and the other swiveled, We are enabled to accomplish what has required double this number of parts heretofore, but in lieu of the lower track and hangers We eniploy other means for locking the door, which Will be explained. To return to the swivel- 'hanger it may be stated by Way of amplification that the swivel-joint is formed by forming a recess l5 in the rear of the rigid lower portion of the hanger and locking the cylindrical stein 1G therein by means of a Wedgeshaped key or block 17, as shown in Fig. 5. In this connection it may be stated that in the modification shown in Fig. 7, in lieu of the switch-block one end of the track is simply bent inward, and in the modification shown in Fig. 8 the track, instead of inclining or converging at one end, is bent inward ab ruptly at both ends alike. In the construction shown in Fig. G the hanger has a Wheel therein to reduce or prevent friction.

As a locking means the following is pro vided: At one end the door is provided With tongue or tenen 18 vand the door-frame with asocket-plate or mortise 19 adapted to receive the tongue or tenen 1S. At the opposite end the door is provided with locking hook or button 20, Which swings around on a pin and hooks at the rear on the door-frame.

Cleats 2l vand 22 are placed on the side of the car as guides and stops for the door when open to stop it and to prevent its swinging outward; also the door may be furnished with a handle .23, by which it is easily grasped to slide it back and forth.

It is evident that other slight changes might be resorted to in the form andy arrangement of the several parts described Without departing from the spirit and scope of our inveir tion, and hence We do not Wish to limit ourselves to the exact construction herein set forth; but,

Having fully described our invention, What We claim as new, and desire to secure by Lerters Patent, is

The combination With a car, a door and a track secured to the car over the opening for the door, said track being made in two sections and arranged to gradually recede from the car body, of a switch block between said sections of the track, said switch block having a curved opening or recess, flanges on said switch block coincident with one Wall of the recess or opening and with a portion of the outer face of the switch block and forming a continuation of one track section, anges on the outer edge of the switch block and forming a continuation of the vother track section. and hangers on the door adapted to run on said track sections and flanges, substantially as set forth. i

vIn testimony whereof We have signed this specication in the presence of two subscribing Witnesses.
