Application filed .May 9, 1913. Serial No. 766,586.

i Illinois, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification.

This invention relates to improvements in the class of hangers for sliding doors commonly known as flexible hangers, in that they comprise a flexible or hinging connection between the frame of the hanger or the portion that rideson the supporting track, and the apron or straps which are secured to the door and serve as the direct suspension means for the latter.

One of the objects of the improvements embodied in this application, is to provide a hanger especially adapted for use with a tu bular track, of simple and strong construction, being made of butfew pieces, and in which provision is made against the derailment or jumping of the frame from the track. I

A further object is to provide a hanger of the class described, in which the door suspended therefrom may swing freely outwardly or away from the structure for which the door is provided, without affecting the vertical alinement of the hanger frame and the position of the wheel on the track, and will maintain the hanger-frame and door in true vertical alinement should the door swing laterally toward the buildm it further object of my invention is to provide an adjustable connection between the hanger frame and the door straps or apron so that the latter may be fitted to doors of varying thickness and the center of the door maintained in the central vertical plane of the track and trolley wheel.

laterally outwardly on the pivot belt; which connects said pendant and the hanger frame; Fig. 3 is a front elevational view of the parts shown in Figs. 1 land 2-, taken at theinner side of the hanger.

Referring to the details of the drawing, the reference numeral 4; indicates the hood portion of a cast iron hanger frame from which extends downwardly a neck i which connects the hood 4 with an extension comprising two lugs each having an upwardly curved toe portion at", and heel portions 4 the latter having flat under-surfaces 4, said lugs or foot extensions being spaced apart as shown in Fig. 3, and having extending horizontally therethrough openings to receive a pivot bolt 8.

Mounted to swing on the portions of the bolt 8 projecting from the outer sides of the lugs l is a stirrup 7 made of a single piece of strap metal bent outwardly from its pivotal point, as at 7, and again bent to provide the horizontal portion 7 which is centrally perforated to receive a bolt 11 which connects the right-angled apron plates 9 and 10 with said stirrup. The upper horizontal portions of the apron plates are slotted to receive the bolt 11 whereby said apron members may be adjusted relative to each other on said bolt and thus adapt them to doors of different thickness placed between and bolted to said members in the usual manner. The slots referred to are not shown in detail because they are well known features in hangers.

12 represents a tubular track formed with a longitudinal slot along one side adapted to receive any suitable supporting bracket (not shown), by which it is connected with a. building. A wheel 5 is mounted on a spindle or axle 6, which has suitable bear ings in the opposite walls of the frame hood 4, the periphery or tread of the wheel con centrically conforming to the tubular track 12.. The inner wall of the vertical portion P of the hanger frame, is formed with a curved surface 4 which is concentric with the walls of the tubular track 12, and extends out to the toe 4: The distance between this curved surface l and the too 4", and the tread of the wheel 5 is such that the hanger cannot be removed from the track by lateral movement, but must be placed upon and disconnected from the track at the ends of the latter.

When the hanger described is in its normal position, the flat under-surfaces 4 of the feet 4, rest against the upper surface of the apron strap 9, and thus maintain ing the vertical position on its track of the hanger frame, such arrangement being clearly indicated inFig. 2. 1

It willbe obvious that the curved inner wall 4 while permitting the free longitudinal sliding of the hanger frame on the track serves as a guide for the hanger, and will also forinan effective stop to prevent derailment of the hanger should the latter be pushed upwardly as an incident of the operation of the door suspended from the hanger.

Constructed as described, it will be seen that the hanger frame proper, including the bearings for the spindle or axle 6, and including the extensions 4, and the 'bearings for the pivot bolt 8, is a single casting.

The pendant portions of my improved hanger, including the stirrups 7 and the apron straps 9-l0, are included in other copending applications for patents, and I therefore do not claim sameper 86, but

What I claiin'and desire to secure by Letters Patent, is

A door hanger comprising a comb nation with apron plates for attachment to a door, and a stirrup ad ustably secured to said plates, a casting provid ng a wheel housing within which is ournaled a wheel, the lower )OltlOIl of which CEtStlD terminates 2 in an integral lug to which said stirrup is pendeiitly secured, a lateral integral projection from said lug against which the apron plates impinge when the door is in a.

vertical plane, and a lateral integral projection above said lug, against which the track upon which said wheel travels is. adapted to abut when said hanger 1S thrown out of its vertical. plane.

In testimony whereof I'aflix my signature in the presence of two witnesses.
