SPECIFICATION forming part of Letters Patent No. 768,799, dated August 30, 1904.

Application iiled April 4, 1903. Serial No. 151,110. (No model.)

T0 @ZZ whom, it may concern:

Be it known that I, JOSEPH R. HERNDoN, a citizen of the United States, residing in Marshall, in the county of Harrison and State of Texas, have invented certain new and useful Improvements in Freight-Car Doors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specitication.

My invention relates to a ush door forV freight-cars and means for operating said door and locking it in a closed condition.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is an elevation of the wall of a freight-car with my door shown in closed and locked position.- Fig. II is a vertical section taken on line II II, Fig. I. Fig. III is a vertical section through the upper end of the door-opening lever, the bolt-lever, and the catch by which the levers are held. Fig. IV is an elevation of the car-wall with the door shown in open position. Fig. V isa vertical section taken on line V V, Fig. IV. Fig. VI is a section on line VI VI, Fig. I.

A designates the wall of a freight-car,pro vided with a doorway B, that extends from the car-floor C to a top bar D. Above the doorway at the exterior of the car-wall is a strip or plate E, to which a hanger track-rail F is secured. The door-frame is rabbeted to receive the door that tits therein, the lower rabbet forming a shoulder G, upon which the door rests. (See Figs. II and V.)

l designates the door, which is supported from the track-rail F by hangers consisting of rail-engaging leaves 2 and door-carried leaves 3, that are connected by links 4, so that the door may be raised and lowered to seat it in the rabbets of the door-frame to rest upon the lower rabbet-shoulder G, as seen in Fig. II, when closed.-

v5 designates locking-bolts, the outer ends of which are loosely fitted in guides 6, set into the door 1, and which are adapted to enter keepers 7, set into the side wall A of the car when the door is closed, as seen in Figs. I and with the keepers and at the same time stops for the bolts are provided. The inner ends of the locking-bolts 5 are pivoted at 8 to a swivel 9, that is rockingly mounted on a pivotbolt 10, by which the swivel is connected to the door l.

l1 is a hand-lever hinged to the swivel 9 at l2 and provided with a transverse aperture I3. (See Figs. III and IV.) The hand-lever 1l is adapted for service in rocking the swivel 9 to operate the locking-bolts 5 for the purpose of effecting connection between said bolts and the keepers 7 and the disconnection of such parts. The aperture 13 in the handlever is adapted to receive an apertured'stud 14, projecting outwardly from the car-door when the lever is swung inwardly to said stud, as permitted by its hinge connection with the swivel 9. A

15 designates a bracket secured to the eX- terior of the car-wall beneath the doorway therein. This' bracket has hinged to it at 16 a door-operating lever consisting of an inner member 17 and an outer member 18, united by a pivot-pin 19, theV outer member being provided with a transverse slot 20. The inner lever member I7 Ycarries a boss 2l, that is adapted to enter a socket-block 23, secured to the lower edge of the door. (See Figs. II, IV, and V.)

24 is a guide-rod mounted upon the car-wall, and 25 is a guide-chain secured to the door l and carrying a ring 26, that rides upon said guide-rod and directs the travel of the lower end of the door as it rides to and fro in the travel of the hangers on the track-rail F.

In the practical use of my door the parts are operated as follows: When the door is in the open position, (seen in Figs. IV and V,) it hangs suspended to the full extentpermitted by its supporting-hangers, and its lower edge occupies a position below the shoulder Gr at the bottom or' the doorway. When the door is to be closed, the operating-lever, consisting of the members 17 and 18, is swung upwardly, so that the boss 21 on its inner member will enter the socket 22 in the lower wall, and at the same time the lower edge of the door is swung outwardly to permit said boss to enter the socket-block 23 at the bottom of the door. The operating-lever is thenswung inwardly toward the door, in which movement the door is lifted, so that its lower edge is raised to the level ol' the shoulder at the bottom ot' the doorway and will ride thereon into the position seen in Fig. II, its upward travel being permitted by reason ot' the ilexible form of the door-hangers. lVhen the parts have been moved into the position stated, the aperture 2O in the door-operating lever receives the stud 14 and tits thereover, as seen in Figs. II and III. The bolt-operating lever 11 is then rocked to throw the bolts 5 into engagement with the keepers 7 by rocking the swivel 9, and the lever is moved inwardly to the stud 14, which passes through the aperture 13 in said lever. been fitted to the stud 14 they are secured by a sliding pin 28. The pin 28 is carried by the bolt-operating lever 11 and connected thereto by a slide-bolt 29. The slide-bolt 29 operates in a slot 11 in the lever 11. The

point of the pin 28, which passes through the aperture in the stud 14, is preferably provided with a seal-wire aperture 30.

It will be understood that when the door is to be opened it is only necessary to disconnect the sliding pin 28 from the stud 14, when the bolt-operating and door-operating levers f After the levers have A may be moved reversely from that in which they were moved in closing and locking the door, and in so doing the door will lirst be unlocked and then unseated from its position flush with the car-wall and may be moved along the wall to unclose the doorway by the hangers riding' upon their supporting trackrail.

The door-operating lever is composed of the two parts 17 and 18, united by the pivotbolt 19, so that the outer member of said lever may swing laterally with respect to the inner member when the door is open and the lever is hanging downwardly, as seen in Figs. IV and V, thereby preventing the lever from being broken by striking against any object encountered thereby.

What I claim isY 1. In aea'r-door of the character described, the combination with jointed hangers, the door hung thereon, and a track for said hangers; of a door-raising lever, a number ot' locking-bolts, a lever for operating same, and one lock for locking simultaneously both the doorraising lever and the bolt-operating lever.

2. In a car-door ot' the character described, the combination with jointed hangers, the door hung thereon, and a track upon which said hangers travel; of a door-raising lever, a swivel, locking-bolts pivoted to said swivel, locking-fingers pivoted to said bolts, a lever for rocking said swivel, and a lock which locksv simultaneously both the door-raising lever, and the swivel-rocking lever.
