CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 575,173, dated January 12, 1897. p

Application filed August 28, 1896. Serial No. 604,184. (No model.)

T' all whom t may concern:

Be it known that I, HENRY J. SoHMIoK, a Vcitizen of the United States, residing in Hamburg, Pennsylvania, have invented certain Improvements in Oar-Doors, of which the following is a speciiication.

The object of my invention is to provide simple and eiiicient means for supporting and guiding the door of a car so that it can be to moved longitudinally in either direction, so as to open or close the doorway, can be closed into the doorway iiush with the side of the car, or withdrawn from said opening and supported in a position close to the car side when the doorway is open. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a perspective view of part of a zo car having doors mounted in accordance with my invention. Fig. 2 is a transverse vertical section of part of the car, showing the door closed into the doorway. Fig. 3 is asectional plan view, also showing the door closed into the doorway. Fig. 4 is a transverse section illustrating a modified form of hanger for the door. Fig. 5 is a perspective view of said modified form of hanger, and Figs. 6, 7, and 8 are sectional plan views showing the door 3o in different positions.

A represents part of the car side, and B part of the roof of the car, D being one of the sliding doors intended to close the doorway in the side of the car.

The door D is suspended by means of arms a a from a block F, which is centrally pivoted at b to a carriage G, provided with grooved wheels d, which are adapted to angular rails H, secured upon the roof of the 4o car, so that the carriage is free to move longitudinally along but is confined vertically to said rails. Each of the rails has at one point in its length an offset f, the offsets of each pair of rails being parallel with each other, so that as the carriage G is traversed longitudinally it will, during one portion of its movement, occupy a position close to the outer edge of the roof of the car and during the other portion of its movement will occupy a position farther inward from said edge, 5o these inwardly-extending portions of the rails being in line with the doorway-openin g in the side of the car.

The operation of opening the door will be understood on reference to Figs. 3, 6, 7, and

8, Fig. 3 showing the door closed, Fig. showing it when the carriage has reached the end of its run on the inner portions of the guiderails, Fig. 7 showing it when the carriage is passing from the inner tothe outer portions o of the guide-rails, and Fig. 8 showing it when the carriage is traversing the outer portions of said guide-rails.

As the door is moved its rear end is swung outward and its front end inward until the carriage reaches the end of the inner run of the guide-rails, a reverse swing of the door being effected as the carriage runs from the inner to the outer portions of the guide-rails until the door finally assumes a position par- 7o allel with the car side, as shown in Fig. 8.

NVhen the door is closed, outward movement of the front end of the same is prevented by a projecting plate g on the front door-jamb and inward movement by a guard-rail h on the inside of the car at the top of the dooropening, so that the hanger-arms a are relieved from strain.

Charing-bands i are applied to the car side in order to prevent contact of the battens of 8o the door with the boarding on the car side as said door is moved back and forth, and a chang-plate m is applied to the outer face of the door at the bottom of the same, this chafing-plate serving by engagement with t-he guard-rail m' to prevent any outward swinging of the bottom of the door when the latter is opened, the door when open being thus held close to the car side. A similar guard-rail may be used at the top of the door, if desired. 9o

Suitable stops n n', located, respectively, on the door and car side, serve to limit the slid# ing movement of the door in opening the same.

In order that the door may be moved backn ward to open it without first pulling the rear edge of the door laterally out of the door-opening, said rear edge of the door, as well as the rear jamb of the doorway, are beveled or inclined, as shown in Fig. 3. I'Ience on imparting a rearward sliding movement to the door the rear edge of the same will be automatically forced out of the door-opening, as shown in Fig. (i.

To prevent the accumulation of snow or ice upon the rail structure on the roof of the car, I provide a hood p, which projects over, covers, and protects the rails, the carriage G, and the block F, from which the dooris suspended, as shown in Fig. 2. These hoods are omitted from Fig. 1, as their illustration would prevent a proper showing of the rail structures.

In Figs. 4 and 5 I have illustrated a modification of my invention in which, instead of a double rail upon the roof of the car, a single rail Il' only is employed, and the block F', from which the door is suspended, has a single vertical wheel d.' running upon this rail in place of the carriage with its pair of wheels Cl, the rail I-I having an offset f, suitably located, so as to carry the door into the dooropening as it is moved longitudinally forward and out of the door-opening as it is moved rearward. In this case the depending arm a' of the block F is swiveled in the bracket on the door, so that the latter can swing on the supporting-block for the same purpose as the door shown in Figs. l, 2, and 3 swings on the pivot Zi. In this case the hood p prevents the lifting of the door so as to carry the wheel d off of the rail H.

Having thus described my invention, I claim and desire to secure by Letters Pat ent- 1. The combination of the car having upon the roof of the same a guideway offset so as to present two parallel longitudinal planes, one farther inward from the edge of the roof than the other, with a hanger-block, a cardoor suspended therefrom, means whereby the movement of said hanger-block is controlled by the guideway on the roof of the car, and a pivotal connection whereby the door is free to swing on a vertical axis as well as to slide, substantially as speci fied.

2. The combination of the car having on the roof of the same a pair of rails constituting a guideway and offset so as to form one portion of said guideway farther inward from the edge of the roof than the other, with a hanger-block having portions engaging said guideway,a door suspended from said han gerblock, and a pivotal connection whereby the door is free to swing on a vertical axis as well as to slide, substantially as specified.

3. The combination of the car having on the roof a pair of rails constituting a guideway, and offset so as to form one portion of said guideway farther inward from the edge of the roof than the other, a carriage having wheels engaging said guideway, a hangerblock pivoted to said carriage, a door suspended from said hanger-block, and a pivotal connection whereby the door is free to swing on a vertical axis as well as to slide, substantially as specified.

4. The combination of the car having on the roof a pair of flanged rails constituting a guideway, and offset so as to'form one portion of said guideway farther inward from the edge of the roof than the other, with a hangerblock, a door suspended from said hangerblock, grooved wheels adapted to the flanged rails so as to be free to move longitudinally thereon,but confined vertically thereto, means for connecting said wheels tothe hangerblock, and a pivotal connection whereby the door is free to swing on a vertical axis as well as to slide, substantially as specified. A

5. 'lhe combination of the car having on the roof an offset guideway, a hanger-block having its movement controlled by said guideway,a door suspended from said hanger-block, and a pivotal connection whereby the door is free to swing on a vertical axis as well as to slide, and a guard-rail on the inside of the car for limiting the inward movement of the front portion of the door when the latter is closed into the doorway, substantially as specified.

6. The combination of the car having on the roof an offset guideway, a hanger-block having its movement controlled by said guideway,a door suspended from said hanger-block so as to be capable of moving longitudinally and also laterally into and out of the doorway, and a guard-rail for limiting the lateral outward movement of the bottom of the door when the latter is open,snbstantially as specified.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.

HENRY J. SOI-IMICK.
