GAR-DOOR.

Specification of Letters Patent.

Patented Oct. 12, 1915.

Application filed March is, 1914. Serial No. 825,647.

To all whom it may concern:

Be it known that we, WILLIE L. RENNER and MARK A. BROWN, citizens of the United States, residing at Dublin, in the county of Erath, State of Texas, have invented certain new and useful Improvements in Car- Doors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in car doors.

One object of the invention is to provide a cheap and novel car door locking device for the door which cooperates with the hangers to cause said hangers to bind the rollers against the track. 1

Another object is to provide a simple auxiliary locking means for the operating levers of the door locking means which is adapted to receive the ordinary car seal.

A further object is to provide a sliding car door which may be swung open inwardly or outwardly, and which will fit snugly within the door casing, thus obviating the necessity for the use of cleats.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is an elevation of the door showing the same in locked position. Fig. 2 is a vertical section on the line 22 of Fig. 1. Fig. 3 is a vertical sectional view on the line 33 of Fig. 1. Fig. 4 is an enlarged vertical section on the line 4-4 of Fig. 1. Fig. 5 is an enlarged detailed elevation of the operating levers in released position. Fig. 6 is a vertical section on the line 66 of Fig. 1.

Referring particularly to the accompanying drawings, 10 represents a door to the upper end of which are suitably secured the leaves 11 of double hinges. These leaves are pivotally connected with the intermediate leaves 12, which are in turn pivotally connected with the hangers 13. These hangers are provided with the grooved rollers 14 mounted on the longitudinally extending track 15 disposed above the doorway. Above the track 15, and parallel therewith, is a substantially Z-shaped guiding track 16 against the inner face of the depending portions of which the vertically extending lugs 17 of the brackets or hangers 13 engage.

Secured to the doorway below the track 15 are. the angle plates 18, behind which the upper edge of the door 10 is adapted to engage, when the door is swung into closed position.

Secured to the outer face of the door, and slightly below the center thereof is a bracket 19, this bracket being provided with a plurality of perforated cars 20 between which are engaged'the cars 21 and 22 respectively of the operating levers 23 and 24. A pivot pin or bolt is passed through the ears 20, 21 and 22, thus pivotally mounting the said levers on the bracket. Loosely connected to each of the hangers 13 is a bar or rod 27, these rods being joined at their lower ends to a singlev link rigidly connected thereto, and indicated at 28, this link being pivotally connected to the lever 24as indicated at 29. The pivotal end is forked as indicated at 30v to permit the free passage of the link 28 thereunder. Pivotally connected on each side of the lever 23, and at theforked end thereof is a downwardly and laterally extending rod or bar 31, the lower terminal of which is bent to extend vertically downwardly as indicated at 32 and guided in a housing 33 mounted on the outer face of the lower end of the door. To the sill '34 of the doorway are secured the socket members 35 which receive the lower ends of the portions 32 of the rods 31 when the door is in closed and locked positions.

As clearly shown, these levers 23 and 24 are arranged to swing downwardly to operative position, the outer endof each of the levers being provided with a transverse slot 36 for the reception of a staple 37 carried by the door. Mounted on the lever 23 is a housing 38 in which is arranged a slidable bolt 39, this bolt having a thumb piece 40 on its upper end and a beveled nose 41 for engagement with the staple as the staple passes through the slot 36 of the lever. This nose is arranged to slide under the staple under the influence of a spring 42 arranged in the housing 38. Formed obliquely through the nose 41 is an opening 43, the ends being arranged on opposite sides of the staple so that the wire of the car seal 44 can be passed therethrough and lock the nose to the staple. This prevents unauthorized movement of the operating. levers.

From the foregoing, it will be seen that by reason of the double hinge, the door is capable of swipging inwardly and upwardly so,

as to rest on the sill, and by reason of the lugs 17 engaging with the guide track 16, the door is prevented from rattling. The angle plates 18 serve as additional means to prevent rattling, and positively hold the up-' per edge of the door against outer movement. l/Vhen the door is in open position, that is when it is moved away from the sill 34, the lower edge of the door drops outside of the sill and below, the door being suspended the full length of the hinges.

It will also be understood that, by the provision of the double hinged hangers, the door can be opened Very easily, even when there is great pressure on the door from within.

To close the door, the lever 24 is thrown downwardly which causes the upper edge of the door to swing inwardly and behind the angle plates 18. The bottom of the door then rests on the sill, and by throwing both of the levers down, the rods 31 are engaged in the sockets 35, and the staple 37 disposed through the slots 36 so that the nose 41 is engaged therewith. Then, by placing the wire of the car seal through the opening 43, the door is locked agamst unauthorized openlng.

What is claimed 1s:

1. The combination with a car door,fand a track therefor, of a bracket mounted on the door, a pair of vertically swinging levers ers and the door, connections between the hangers and one of the levers, locking bolts slidably mounted on the door and pivotally connected to the other lever, the said levers being provided with slots, a staple carried by thedoor and received in the slots, and an auxiliary locking device carried by one of the levers for engagement in the staple.

2. The combination with a car door, frame, and track, of hangers mounted on the track, double hinge connections between the hangers and door, a pair of levers pivotally mounted on the door, locking bolts carried by the door for cooperation with a part of the frame, links connectingone of said levers and the hangers whereby the door is capable of being lifted and swung from its frame and connections between the sliding'bolts and the other lever for releasing the bolts, and means carried by one of the levers for automatically locking the levers to the door.

In testimony whereof, we afiix our signa tures, in the presence of two witnesses.
