DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 755,607, dated March 29, 1904.

Application filed May 29, 1903. Serial No- 159227. (No model.)

I To all whom it may concern:

Be it known that I, FREDERICK F. Brsononr a citizen of the United States of America, and

a resident of Chicago, in the county of Cook and State'of Illinois, have invented 'certain' new and useful Improvements in Door-Hangers, of which the following is a specification.

The present invention relates to single-track hangers for sliding doors and the like, and has for its object to provide a simple, light,

and durable construction and arrangement of parts in which a substantial attachment and support of the track-railis provided and the accidental disengagement of the pulley and pulley-frame from the track-rail prevented without liability to binding of the parts, all as track-rail, which in the present invention is formed by an angle bar of metal, the longitudinal apex ofwhich is arranged uppermost to afford an inclined track-surface on each side of such apex, as shown; I

2 is one of the supporting-brackets of the track-rail, having the usual base for attach ment to the wall of the building or other object and a horizontallyprojecting? arm 3'for attachment to the track-rail, as hereinafter described. 1.

. 4. is an angular or oblique extension on the outer end of the arm 2 aforesaid, and such extension is adapted to fit the under surface of the angle-bar track-rail land aiford an extended abutment or support for such rail.

5 is an angular tongue near the outer end of the arm 3 aforesaid and having a spaced relationto the aforesaid extension 4 to form a receiving-recess'for the inner edge of the track-rail to aid in the rigid and substantial attachment of said rail to the supportingbracket.

ing the operation of 6 is a transverse screwor rivet passing through the rail 1 and the extension 4. to lock the parts in position after assemblage.

7 is the track-pulley, the periphery of which is formed with an angular groove to fit the track-rail aforesaid and be guided thereby in the actual use of the hanger. i

8 is the pulley-frame, the upper portion of which is of an arched form'to afi'ordbearings for the respective ends of the journal-shaft of'the track-pulley 7, While its loweriportion is of the usual strap formfor attachment to the face of the door. In the present construction the upper arched portion of the pulleyframe 8 has an expanded top or hood 9 for inclosing the track-pulley from the weather, 8.50., and said hood is provided with a centrally-arranged gap 10 at one side edge, which is adapted to receive the nozzle of an oil-can and maintain the same in proper position duroiling the pulley and track.

11 is a lateral lug on the inner face of the pulley-frame 8 and against which the upper end of the door is adapted to'abut in the application of the pulley-frame to such door. In the present construction such lug is of an angularform and is adapted to constitute a bearing-support for the retaining-roller by which the pulley-frame and pulley are held from accidental disengagement from the track. s

12 is the retaining-roller, which in the present construction is journaled in an oblique direction upon the lateral lug 11 aforesaid and has bearing upon the-under side of the outer inclined. longitudinal member of the track rail, as shown. With the described arrangementa limited movement of the pulley-frame and its connections with relation to the track- 'rail and in an oblique direction is permitted without a disengagement from the track-rail,

and by this provision any ordinary tendency of the parts to bind in the normal operation of the appliance is avoided] Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hanger for doors and the like, the combination of atrack-pulley, a pulley-frame,

I a track-rail of an angle-bar fo'riii with its apex arranged'uppermosmand a supporting-bracket having an obliquely-disposed upward extension at its outer end fitting the under side of said track-rail, substantially as set forth.

, 2. In a hanger for doors and the like, the

oombinationof atrack-pulley, a pulley-frame, Q a track-rail of an angle-bar form with its apex, arranged uppermost, and a supporting-bracket having an obliquely-disposed upward extension at its outer end fitting the under side of said track-rail, and provided with a tongue having spaced relation thereto to form a receiving-recess for the inner-edge of the trackrail, substantially asset forth. .7

,3. In a hanger for doors and the like, the

I combination of a track-pulley, a pulley-Frame, a track-rail of an angle-bar form with its apex arrange d uppermost, a supporting bracket as set forth.

having supporting connection withsaid rail, w and an obliquely-arranged retaining-roller journaled on the'pulley-frame and having ,bearing upon the under side of the inclined outer member of the track-rail, substantially as set forth.

4. In a hanger for doors and the like, the

combination of a track-pulley, a pulley-frame,

a track-rail of an angle-bar form with its apex arranged uppermost, a supportingbracket having supporting connection with said .rail, a triangular lug on the inner side of the pul- Icy-frame, and an obliquely-arranged retaining-roller journaled on said lug and having bearing upon the under side of the inclined outer member of the track-rail, substantially 5. In a hanger for doors and the like, the

combination of a track-rail of an angular form, a grooved track-pulley, and a pulley-carrying frame having a hood atits upper end, said hood having a central gap at one of its side FREDERIOKF. 'B'isoHoFF.
