{Specification of Letters Patent.

Patented May 1d, 1918.

Application filed June80, 1814. Serialilt'o. 177,962.

To all whom it may concern:

Be it known that I, GEORGE M. PIPER, a citizen of the United States of America, and a resident of Cedar Falls, Blackhawk county, Iowa, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification.

My invention relates to improvements in door-hangers, and specifically the object of my invention is to provide a hanger between hinged doors and a carriage movable upon a track positioned thereover, which may always be operable in any positions of the doors relative to the track without coming to a dead center.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure 1 is a front elevation of my improved doorhanger as operatively connected between a carriage on a track and a door thereunder, parts of the track and door being broken away; Fig. 2 is a plan of the hinge-part of said hanger, Fig. 3 is a cross-section of said track, showing said carriage therein, and Fig, 4 is a horizontal section taken through the doorway of a building, showing doors hinged to a jamb thereof and to each other and operatively connected to an overhead track by my improved hanger, dotted lines indicating different opened positions of said doors.

Similar numerals of reference denote corresponding parts throughout the several views.

Referring first to Figs. 1 to 3, the numeral 19 denotes a, tubular track supported on a building 12 above its door-opening and doors 89. The bottom of the track has a longitudinal slot 20, providing a pair of parallel runways u on which may roll a carriage having ro lers 18 pivotally mounted on a body 17, said body having a hanger 16 with depending threaded stem 13.

The door 9 is hinged at 11 to one jamb of the doorway, while the door 8 is hinged to the door 9 on hinges 10.

A hinge formed of the parts 1 and 2, having alined sockets 5 and 6, whereby they are pivotally connected on a pintle 3, has its part 1 secured to an upper corner of the door 8 by means of bolts 7. The hinge-parts 1 and 2 have a propor rule-joint 4, which thus limits the relative movements of these parts so that they cannot swing to or be yond a dead-center with said doors. The hingep-art 2 has a verticalorifice near its free end to permit it to be mounted to rock on the stem 13, and is secured thereon for vertical adjustment by means of nuts 14 and 15 engaging its under and upper surfaces.

The track 19 is, in Fig. 4, shown as supported on the building 12 set off from the doors 8-9 when the latter are closed, for the purpose of a diagrammatic illustration, the usual position of said track bein immediately above and in the plane of t e doors when the doors are so hinged to the building as to underlie the track.

When the doors underlie the track, the hinge-parts 12 are fully extended as shown in Fig. 2. In Fig. 4c, the dotted lines display one position of said doors 89 when folded together so as to extend outwardly at a right angle to the building, in which position the hinge-parts are flexed at less than a right-angle. The second dotted line osition shown, indicates the position of said folded doors when swung toward the building.

If the track were immediately above said doors, the hinge-parts 12 would be in the full line positions shown in Fig, 2, with the doors positioned closely parallel to the building, but the hinge-parts prevented by its rop-joint from passing to or beyond a dea -center. However, it will be obvious that when the track is spaced away from said doors as shown, the hinge-parts will not arrive at their stopped osition.

This arrangement of the oors, their relations to each other, to the building and said track as connected to the latter by said prop-joint hinged movable door-hanger, permits the doors to be freely swung to any position outwardly, and be as freely returned to a closed position, without any binding, or interference with their operation due to the hanger parts passing relatively to or beyond a position of dead center. The doors are thus supported from sagging, freely movable, and easily actuated from a closed to an entirely opened position, and the reverse.

It should also be noted, that the use of my improved door-hanger and prop-joint hinge permits the doors to be positioned either in a plane passing through said track, or beyond said plane as illustrated, whereby in &
