Specification of Letters Patent.

Patented Sept. 16, 1919.

Application filed June 14, 1918. Serial No. 239,985.

To all whom it may concern:

.Be it known that I, CLINTON G. Ti-ionrn, a citizen of the United States, residing at Rosedale, in the county of Parke and State of Indiana, have invented certain new and useful Improvements in Car-Doors, of which the following is a specification.

This invention relates to doors of that class which lie when closed flush with the wall or side of the structure to which they are applied, and which are opened by two movementsfirst, bodily outward from the side of the structure, and secondly, a sliding movement longitudinally parallel with the side of the structure to uncover the opening.

The object of the invention is to provide a simple and efficientdoor of this character which may be swung snugly within the door opening and easily shifted laterally to open or close it.

Another object is to provide an improved form of hanger or carrlage for supporting the door.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the c0mbination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the inven- 'tlOn;

In the accompanying drawings Figure 1 represents a side elevation of a portion of a freight car showing this improved door applied and in closed position,

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a detail vertical section on an enlarged scale taken on the line 3-3 of Fig. 1,

Fig. 4 represents a side elevation of a portion of a car and door with parts broken out and in section, and

Fig. 5 is a detail horizontal section.

In the embodiment illustrated, a portion of a car body 0 is shown, the side wall of which has a door opening to be closed by a sliding door I), the mounting of which constitutes the gist of this invention.

To the door at suitable distances from the opposlte ends thereof are journaled two rock shafts 1 and 2, which are securely held to the door by means of bearing clips 3 in which they are free to turn. Each rock shaft is provided at its upper end with an L-shaped crank bend 4c- The vertical portion of each bond is secured to a carriage in the form of a casting 5 and is adapted to turn therein." These carriages 5 are mounted to travel in an upper horizontally disposed track 6, secured to the wall C above the door opening. Each of these carriages is equipped 6 5 with rollers 7 and 83, mounted on a, shaft 11 in transverse ahnement and whlch are deslgned one to engage the edge of an upturned flange 9 at the front of the track and the other the lower face of a laterally extending flange 10 at the rear thereof. This track 6 is made in the form of a housing with an opening in its lower wall or bottom through which the carriages 5 extend and in which they travel, said housing operating to protect them against the weather. Each of the carriages 5 is shaped to fit and slide easily in the housing 6 and each has a shank or neck 5 extending between. the flanges 9 and 10. A lateral extension 5 projects forwardly from shank 5 and 1s apertured to re ceive the end of one of therock shafts. A. recess extends upwardly from the base of the extension 5 in whlch roller 7 is mounted,

the side walls of said recess embracing flange 9and operating as guidesto prevent lateral movement of the carriage. It will be seen that by having roller 7 travel on flange 9, the weight of the carriage will be support ed by said flange and roller 8 engaging 9O flange 10 will balance the carriage and cause it to move easily.

The carriages 5 are connected by a rod 12 shown clearly in Fig. 4 which holds them in properly spaced relation and also operates as a brace.

The rock shafts 1 and 2 have crank por tions 18 and 14; intermediately of their ends with which are engaged the opposite ends of a cross bar 15 having a bearing 16 midway its ends and in which is journaled one end of a crank shaft 17. This crank shaft 17 is revolubly mounted in a bearing 18 fixed to the outer face of the door D and has a laterally extending handle 19 at its lower end designed to fit over a keeper 20 positioned in its path on the door D, said handle having a slot 21 for this purpose. After the handle has passed over the keeper 20 a key 22 fixed to the door by a flexible element here shown "Fig. 1.

4 a I u a ing shown in closed position as In Fig. 1, the

In the use of this apparatus, the door be key 22 is first removed to release handle 19, which is swung outwardly thereby rocking the crank shaft 17 and moving the bar 15 longitudinally toward the right, which causes the rock shafts 1 and 2 to turn in their bearings 3, which causes their crank bends or upper ends 4 to swing inwardly and to bodily lift the door D out of its opening and when it has been so lifted it may be moved longitudinally on the tracks 6 and 25 to uncover said opening.

To close the door, the operation is reversed.

It will thus be seen that the structure above described is simple and strong and reliable in its operation and may be readily applied to any car or building either already made or in the course of construction.

The foregoing description and the drawings have reference to what may be considered the preferred or approved form of m invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, etc., as may prove expedient and fall within the scope of the claimed inventio Having thus fully described my invention,

Copies of this patent may be obtained for five cents each, by addressing the what I claim as new Letters Patent, is

l. The combination with a wall having a door opening, tracks above and below said opening, the upper track being in the form of a housing having a longitudinal opening in its bottom with an upstanding flange at one side edge of said opening, and a lateral flange at the other side, a carriage mounted in said housing with transversely alined rollers positioned one to travel on the top edge of said upstanding flange, and the other on the lower face of said lateral flange, said carriage having a forwardly projecting lateral extension, a rock shaft carried by and depending from said extension and rotatable therein, means connected to turn said rock shaft, and means for locking it in one position to hold the door closed.

2. The combination with a wall having a door opening, a track above said opening in the form of a housing having a longitudinal opening in its bottom with an upstanding flange at its outer edge and a lateral flange at its inner edge, the lateral flange being in and desire to secure by a plane above the upstanding flange, a car-,

riage mounted to travel in said housing having a shank extending through said bottom opening and provided at its lower end with a forward extension, said carriage having a recess extending upwardly from the base of said extension, a pintle extending through said shank and having a roller thereon positioned in said recess to travel on the edge of said upstanding flange, and another roller to engage the lower face of said lateral flange, and a rock shaft rotatable in said extension.

In testimony whereof I aflix my signature in presence of two witnesses.
