SUPPORTING MEANS. Fon snrnnve DOORS.

Specification of Letters Patent.

Patented Nov. 23, 19115.

Application filed May 3, 1915. Serial No. 25,371.

To all whom t may concern Be it known that I, dass L. DEAN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Support ing Means for Sliding Doors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to supporting means for sliding doors and more particularly those of the type that are used on barns and like structures where parts are exposed to the weather, the invention including mea-ns whereby the door bearings are housed and whereby the track on which the door runs is so secured as to prevent accidental dislodgment if one of the supporting parts becomes loosened.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

Referring to the drawings, Figure l is a view in elevation of a door mounted on supporting means that embody features of the invention; Fig. 2 is a plan view enlarged of a strap, strap hanger and roller; Fig. 3 is a view in detail of the strap hanger and roller; Fig. 4 is a view in section in detailV of the strap hanger and roller; Fig. 5 is a transverse section in detail showing the housing of the roller; Figs. 6, 7 and 8 are views in detail of the track rail and bracket for supporting the same; Fig. 9 is a view showing the form of a blank from which the roller housing may be readily formed.

In the drawings, a track rail l that preferably has a rounded upper face and at least has a depending longitudinal flange 2 is supported by a series of brackets each having a body 3 with projecting upturned integral flanges 4 and an attaching screw or bolt 5 whereby a bracket may be applied to a wall. A clamping member 6 is oppositely disposed to the flange 4 on the body of the bracket 3, which is notched to overlie, the clamping member and flange 4 coperating to grip the longitudinal flange of the rail l. Thus the rail body rests on the integral part 4 of the bracket and is retained there by the clamping member 6, binding screws 7 or the like being used to draw the parts together.

A suitably flanged pulley 18 is journaled on a hollow spindle 8 that operates as a tie to connect the inner wall 9 and the outer wall 10 of a pulley housing. The latter is formed of a suitable blank such as shown in Fig. 9 folded between its margins whereby an upper or cover wall 11 holds the side walls 9 and 10 in spaced relation, the marginal portions 12 of the wall lObeing inturned and abutting either directly against the inner wall 9 or against a Ushaped hanger 13, the arms of which are not only riveted as indicated at 14 but are also bent to hook over and bear on the top part ll. Preferablythe spindle 8 has a cylindrical bore with oil holes l5 whereby the bore may be packed with wicking and lubricant and the end closed in any convenient manner, thus affording constant supply of oil or the like in the pulley hub. Preferably a flange 16 on one end of the member 8 and a cotter pin 17-on the other end effect the locking of the walls 9 and 10 from separating.

As a result of this construction a support for a sliding door obtained that provides a very rigid support which is readily applied to a barn or like structure.

The pulley housing is such as to prevent ice and snow from clogging the action of the pulley.

Ubviously, changes in the details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is 1. Door supporting means comprising a plurality of track hangers each consisting of a bracket having an outer upturned integral flange, a cooperating clamping member astride the bracket, a rail adapted to be gripped between the flange and clamping member, means for securing the clamping member and flange together, pulley housings each consisting of a single piece of sheet metal bent to form top, side and end walls, a pulley spindle securing the walls of the housing in position, a pulley on the spindle adapted to ride on the rail, and a U strap on each pulley housing for attaching a door thereto.

2. In door supporting means, a sheet metal housing for a pulley comprising a blank bent transversely between its ends to form front, top and back walls, the marginal portions of theJ back wall being bent forward into contiguity with the margins of the top and front wall, a hollow spindle having an annular flange at one end thereof extending through alined openings in the front and baok- Wall, a Cotter pin `seczuring In testimony whereof I aflix my signature the spindle imposition, an ofil duet beingin presence of two Witnesses. provided from the interior o the s indle,v Y

a pulley rotatable on `the spindle, arid a U JESS L' DEAN' 5 strap having inturned end portions that Witnesses: overlie the top Wall of the housings against t C. R. STUHNEY, oneside of which the strap is secured. ANNA M. Dorm.
