DOOR-HANGER.

Specification of Letters Patent.

Application filed March 18, 1908.

Patented Nov. 2, 1909. serial No. 421,951. i

To all whom 'it may concern:

Be it known thatI, GEORGE T. BUDDLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Door-Hangers, of which the following is a specification.

My invention pertains particularly to improved means for hanging elevator doors. However, certain features of the invention are also applicable to doors for other purposes.

My invention is illustrated in its preferred embodiment in the accompanying drawings, in which- Figure l is a broken View in inner elevation of the open frame or wall of an elevator shaft and the door combined therewith in accordance with my invention; Fig. 2, a broken vertical section taken as indicated at line 2, Fig. 4, and showing the relation of the upper part of the door, the

track and the hanger through the medium of which the door is supported on the track; Figs. 3 and 4, vertical sectional vie-ws taken respectively at the lines 3 and 4, Fig. 2; and Fig. 5 is a perspective view of one of the removable hub-sections or bushings with which the doorsupporting wheels are equipped.

In the construction illustrated, A represents the open framework or skeleton-wall of an elevator-shaft; A1, a horizontal track carried thereby; B, an elevator-door, and C a hanger for-the door.

The walls of the elevator-shaft A may be of any approved construction. In that illustrated, the framework has, as a part thereof, upright posts c, al, which carry laterally or inwardly projecting bosses a2 which support the track A1.

The door B may be of any approved construction. As shown, it comprises vertical marginal posts b; a top cross-bar b1; a bottom cross-bar 52,' an intermediate cross-bar b3, and vert-ical rods b4 joining said crossbars.

The hanger C is preferably of the form shown, comprising hanger-arms or brackets c, 01,' a pair of rider-bars c2, c3, secured to the upper portions of said brackets on opposite sides thereof, so as to lie on opposite sides of the plane of the track A1, and peripherally-grooved wheels c4 mounted on the track A1 and having trunnions 010 which indirect-ly support the bars c2, c3 of the hanger. The bars c2, c3, are connected intermediately by studs c5 equipped with sleeves or rollers c6. These roller-equipped studs serve to stiffen and tie the bars together in spaced relation. The track A1 is equipped with screws or projections c7, cs, in the paths of the wheels, serving to limit the movement of the wheels in their extreme movements. The bars c2, c3, are provided at their lower edges, between the studs c, with recesses c9 adapted to accommodate the trunnions of the wheels in the operation of hanging the door, or when it is desired to remove the wheels for the purpose of renewing the trunnions or bushings of the wheels. Each wheel c4 'has trunnions 01 projecting from both sides,

and upon said trunnions are journaled hubsections or bushings c having flanges 012 which flank the sides of the wheel and lie adjacent to the inner surfaces of the bars c2, c3. Each of the hanger-brackets c, c1, has an enlarged upper end-portion notched on its opposite sides to receive the bars c2, c3, and has an inwardly offset lower portion behind which the track A1 lies. Near the lower end of the offset portions of the bracket is a lateral Harige C13 adapted to lie above the edge of the top cross-bar b1 of the door, and the lower end of the bracket affords a `Harige c14 which embraces the inner surface of the bar b1. The flange c13 is connected with the upper edge of the door by screws c which support the door. The bars c2, cS are connected by bolts c1G with blocks a' which are vertically movable in slots x1 in the upper portions of the bracketarms c, c1; the blocks being adjustable by means of screws x2 which are secured through the walls :r3 above said slots and bear upon the upper edges of the blocks. `When the screws are turned down, the bracket-arms c, c1, are elevated with relation to the bars c2, c3, thereby elevating the door. The upperedge of the rail is provided with a recess f1 preferably with an abrupt shoulder f2 and a curved surface f3. f

rIhe bushings c11 are preferably made of softer material than are the peripheries of the wheels, and the track and bars which are engaged respectively by the wheel-peripheries and by the bushings, so that the principal wear will come upon said bushings. When necessary, the door may be blocked up, the studs c5 may be removed, and

the wheels may be taken out byl bringing their trunnions to a position corresponding with the recesses c in the lower edges of the bars c2, c3.

The operation will be readily understood: The door may be moved upon its track in the usual way, the wheels traveling on the rail A1 and the trunnions moving relatively to the bars c2, c3 of the door. n case of any tendency to bind, the trunnions 010 will turn within the bushing 011,' and, when necessary, the trunnions will slide with relation to the bars c2, 03, while the wheels are traveling on the rail A1.

Near one end of the rail A1, and beyond or outside the screw c7, is a recess g in the upper edge of said rail` Then the screw 07 is removed, the adjacent wheel may be removed by bringing it to the location of the recess g. In like manner, the other wheel may be removed by first removing the screw cs and utilizing the recess f1 to accommodate the wheel in the operation of removal.

In the event of sagging of the door, the set-screw :r2 maybe turned in farther to elevate the door.

rlhe foregoing detailed description has been given for clearness of understanding only, and no undue limitation is to be understood therefrom.

What I regard as new, and desire to secure by Letters Patent, is-

l. The combination of a frame provided with a track, wheels mounted on said track and provided with projecting trunnions, removable bushings on said trunnions, a door equipped with hangers, and rider-bars carried by said hangers bearing on said bushings.

2. The combination with the framework of an elevator shaft equipped with a rail, of a door, a pair of hanger-brackets connected with said door and equipped with riderbars provided at their lower edges with recesses, and wheels mounted on said rail and having trunnions supporting said rider-bars between said recesses and the ends of said bars.

3. The combination with the framework of an elevator shaft, of a rail carried thereby, wheels mounted on said rail, a door provided with hangers and having rider-bars adjustably secured at their ends to said hangers, said bars lying on opposite sides of the rail, and a recess in said rail to permit removal of a wheel.

4. The combination with a frame-work of an elevator shaft, of a rail carried thereby and provided on its upper edge with recesses, removable screws carried by said rail adjacent the recesses and projecting from the rail, a door, a pair of hanger-brackets, wheels mounted on said rail and equipped with trunnions, and rider-bars connecting the upper end-portions of said brackets and supported on said trunnions.

5. The combination with the frame-work of an elevator-shaft, of a rail carried thereby, a door, a pair of hangerbrackets slotted transversely of their upper extensions, wheels mounted on said track and equipped with trunnions, blocks adjustably confined within said slots, rider-bars attached to said blocks and supported on the trunnions of said wheels, and screws for adjusting said blocks, for the purpose set forth.

6. The combination with the frame-work of an elevator-shaft, of a rail carried thereby, a door, a pair of hanger-brackets, wheels mounted on said track and equipped with trunnions, removable bushings on said trunnions, rider-bars adj'ustably secured to said brackets, adapted to ride on said bushings and provided with a recess in their lower edges between said wheels, and removable studs at opposite sides of said recess surrounded by sleeves and adapted to hold said track-bars in spaced relation, for the purpose set forth. l
