ABRAHAM LINCOLN CHAMPION, OF MACON-GEORGIA.

FREIGHT-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 768,513, dated August 23, 1904. Application iiled April 9, 1902. Renewed February l5, 1904., Serial No. 193,554. (No model.)

, CHAMPION, a citizen of the United States, and

aresident of Macon, county of Bibb, and State .of Georgia, have invented certain new and useful Improvements in Freight-Oar Doors, of which the following is aV specification, reference being' had to the accompanying draw-- ings, forming a part thereof, in which similar letters ofk reference indicate corresponding parts.

|This invention relates to improvements in freight-car doors and means for hanging them, the object thereof being to provide an eiiicient and durable device of this character which is adapted to freely slide back and forth on a straight line with but a minimum of friction and which is durable and efficient in general operation.

The invention will be hereinafter fully described, and specifically set forth in the anneXed claims.

In the accompanying drawings, forming part of this specification, Figure l is a side elevation of a part of a car-body having my improvements'attached thereto. Fig. 2 is a vertical sectional elevation taken on aline .fr of Fig. 1, and Fig. 3 is a plan view of a part of the upper supporting-rail.

In the practice of my invention I secure to the side A of the car-body by bolts, rivets, or-

other suitable means and located over the doorway ct a longitudinal rail B, which is provided with-a recess throughout-nearly its entire length. Upon each end of the rail B is a short recess b, which recesses engage a longitudinal plate B', the parts being secured together by means of the bolts C and nuts c, the outer surface of the plate B being even with the end parts. of the strip B. The rail B is of suiiicient length to allow the door to entirely clear the doorway when said door is opened, and vertical' stops D are located at each end to limit the sliding movement of the door. Beneath the doorway, running parallel with lthe rail B, is a similar rail, which comprises the recessed part E and outer plate E', the parts of this rail being set at right angles to the rail B. Located between the two sections of the rail B is placed a series of rollers and slides freely thereon.

F, which are each provided with an integrallyformed hub f and spindle or, shaft f', which are journaledv in openings in the parts B and B and which registerwith each other, whereby the rollers may freely revolve upon hori- Zontal axis. A set of rollers Gr, having integral hubs and spindles similar to the rollers F, are journaled between the two parts E and E of the lower rail, and these rollers revolve upon vertical axis.

Secured to the door C' at the top thereof is a hanger H, which bears upon the rollers F Lateral displacement of this hanger is prevented by the downwardly-eXtended Iiange /L upon the backl thereof. A similar hanger I, but which is in inverted position, is placed upon the bottom of the door, and this hanger bears upon the rollers Gr. at its vertical part c', an `upwardly-extended iange c" being formed at the back to prevent lateral displacement. By the use of this door and novel means for hanging same it is obvious that the door will slide back and forth freely without catching and lateral pressure either from the inside or outside will not tend to in any way displace the hanging mechanism.

Any suitable fastening devices maybe employed in connection with the door, and itis readily adaptable for attachment to the ordinary car-body.

Having now `described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination with the body of a car of rail E, E', recessed as specified, attached to the said car below the doorway thereof, so that the said recess will be at right angles to the surface of said body, a plurality of rollers G, formed with hubs and spindles integral therewith, and journaled in the parts E, and

IOO

and with its recess at right angles to the surface of the body of said ear, a plurality of rollers G, formed with hubs and spindles integral therewith and journaled in parts E, E', ot said last-named rail, so that their spindles said last-named rollrecess of the said rail of a ear-door the hanger H fastened to will be vertical and that ers will revolve in the E the top thereof, bearing upon the rollers F. and sliding thereon, the downwardly-extelnling` flange z, upon the back o'l said hanger and arranged to prevent lateral displznenwnt of said door, the inverted hanger l fastened to the bottom or' said door bearing npon the rollers (5r, and sliding thereon, and the npwardly-extending liange v', upon the back ol said hanger l, arranged to prevent lateral displacement of the bottom ol said door.

1n testimony that l claim the foregoing as my invention l have signed my name, in presence of two witnesses, this 15th day of February, 1902.
