OF CHICAGO, ILLINOIS.

Doon-HANGER.

SPECIFICATION forming part of Letters Patent No. 317,496, dated May 12,1885. V

Application filed uly 28, 1884. (No model.)

To ail whom t may concern:

Be it known that I, CHAnLEs W. BUL- Lann, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Door-Hangers, which is fully set forth in the following speciication, reference being had to the accompanying drawings, in which- Figure lis an elevation of a sliding door having my device applied thereto, parts being broken away to show the construction; Fig. 2, a sectional view on the line as x, Fig. l; and Fig. 3, a detail view.

My invention relates to door-hangers-such as are used in supporting and guiding sliding doorsand is in the nature of an improvement upon the door-hanger shown and described in my prior application, No. 136,463, filed June 30, 1884.

I will now proceed to describe my invention, and then specifically point out the novel features in the claims.

As in my previous application above mentioned, the door A is suspended from the. rails B, beveled, as shown at b', by means of the wheels C, upon the axles c of which the brackets D rest. This bracket is preferably constructed of wrought iron, and is composed in the present instance of the three arms d d d2, the central one of which passes down through a plate, G, secured on the door, as shown, and is screw-threaded to receive a nut, c, arranged in a mortise in the door below the said plate, whereby the bracket is adj ustably secured on the door. The arms d l2 also pass through said plate and hold the bracket in line with the door, sliding freely in the plate to permit the adjustment ot' the bracket by means of the nut c. Tubular guides b may be formed on the plate G for these arms to pass through. The crossbar d3 of the bracket rests upon the axle c of the wheels C to support the door.

In my previous application, hereinbefore mentioned, I employ, as a device, to prevent any lateral canting of the door, a conical roller mounted to revolve on one of the vertical arms of the bracket as an axis. If by any irregularity of the rails B this roller were brought against both rails at the same time, it would not turn, and would cause a frictional resistance to the movement of the door. To obviate this I mount on one or both of the arms d d2 rollers E, the axis of which is at right angles to the beams. Preferably these rollers may be adjustable, being mounted on suitable gudgeons, e', on a sleeve E', surrounding the arm and clamped thereon at any desired point by a set-screw, c2. With this construction the rollers may be so adjusted as to bea-r constantly on the beveled surfaces b of the beams B, thus preventing any tilting of the door laterally. The ends of the gudgeons are hammered down to retain the rollers, and washers c3 may be interposed between the said ends and the rollers.

It is obvious that a transverse axle mounted in a suitable bearing in the frame, and having its projecting ends suitably shaped, would accomplish the same result inthe same manner,

and also that rollers of other shapes than that shown may be employed.

It is also obvious that these rollers may be applied with other forms of brackets differently attached to the door. Itherefore do not wish to be understood as limiting myself to the precise details herein described, and shown in the drawings, as many mechanical changes therein ma-y be made without departing from the principle of my invention.

Having thus described vmy invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the door and the beams beveled on their inner faces, of brackets secured to the door and having wheels to rest upon the beams, and rollers mounted i on said brackets with their axes at right an gles to the beams, and arranged to bear against the beveled faces thereof, substantially as and for the purposes specified.

2. The combination, with the door and the beams beveled on their inner faces, of brackets secured to the door and having wheels to rest upon the beams, and rollers adjustably mounted on said brackets with their axes at right angles to the beams, to bear against the beveled faces thereof, substantially as and for the purposes specified.

3. In a door-hanger, the rollers E, mounted on sleeve E, adjust-ably secured on bracket D, substantially as and for the purposes specified.

4. The combination, with the door and the substantially as and. for the purposes specibeams beveled on their inner faces, of the ed. brackets adjustably secured to the door, and CHARLES W. BULLARD.

having wheels to rest upon the beams, and Witnesses 5 rollers adjustably mounted on said brackets 1 with their axes at right angles to the beams, W' C' ('ORLIES to bear against the beveled faces thereof,
