T ctZ wholt it 71mg/ concern: Y

Beit known that I, LAURA A. CLMER, a citizen of the Unitedy States, residing at Chicago, in the county of Cook and' State of Illinois, have invented anew and useful Improvement in Door-Hangers, of which the following is a specification. l

My invention consists in an improved door.- hanger; and my especial object is to provide a simple, cheap, and particularly eective ballbearing hanger of this nature.

In the accompanying drawings, which show my Aimproved hanger in its preferred form in use in connection with a door, Figure 1 is a broken or fragmentary elevational view of a structure having a door suspended by means of the improved hangers; Fig. 2, an enlarged vertical transverse section at line 2 of Fig. 1, and Fig. 3 aninner face View of a detached ball cup or cage.

In the preferred construction each hanger is supplied with a relatively large track-ball which travels between an upper and a lower track-railV and is itself antifrictionally journaled on ball-bearings in two iianking ball cups or cages carried by theV hanger. Normally the track-ball rolls on the lower trackrail; but when the door is lifted its contact is changed to the upper rail, whereby derailing is prevented and binding rendered impossible.

A represents a door B, uprights anking the door at the desired distance apart; C, a cross-beam D D', upper and lower track-rails,

respectively, and E E hangers mountedon said track and atttached to the door.

Each hanger-framecomprises, preferably, an inverted-U-shaped member having an inner vertical side piece a, top connecting-web ct, outer vertical side piece a2, a downward-extending attaching-shank as, and a separately'- formed block a4, secured by a rivet o5 andY forming, virtually, a lower web joining the two side pieces.

Each hanger-frame preferably is equipped with one track-ball F, confined between annular rows of bearing-balls b b', contained in removable cups G Gr,. respectively. The hanger-frame is cast or formed integrally, with the exception of the block d4, and is provided with annular perforations to receive the cups G G'. The cups, preferably of steel, are formed with fianges c and inner retainserial No. 721,842. no man.)

ing-lips c', the former of Which'it into annular recesses, so as to be flush with the outer surfaces, as shown. Screws the heads of which when countersunk bear partly on the flanges c, serve to secure the cups in place. Retaining-washers may be provided for the balls, if desired, though none are shown.

The rails D D' are of less thickness than the block CL4, and spaces are also provided above and below them to obviate danger of binding. The rails are concaved to receive the track-balls, and the upper rail is only sufficiently above the track-balls to aord the necessary clearance. Thus confined it is impossible for the door to get oif lthe track or to bind.

The track-rails are preferably of steel and are secured together at the ends by common supporting-brackets H. These brackets may be dispensed with, however, and direct attachment to the building structure employed.

Where used, they will be of suitable form to adapt them to the conditions present. Where secured to uprights, as shown, they may be simply short angle-irons. v p

The hanger is adaptedfor use with doors and gates in many situations, such as barndoors, elevator-doors, parlor-doors, tbc. The form of the hanger-frame and its mode of attachment to the door may be varied to suit vvarying conditions. of hangers maybe used on a door, and Where the track is a long one Vit may become desirable to provide intermediate supports forthe lower rail, in which case said rail could not be completely encircled by the han ger-frame, as is evident. Y f

, The track-ball may be replaced by an antifrictionally-journaled revolving member of other form and manyof the advantages of my' construction still be retained. In operation the track-ball while performing the function of ashaft revolving on an axis normal to the door also shifts or turns in other directions, whereby new wearing-surface is constantly presented to the points of contact.

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

l. The combination of avdoor, or the like, suitably-supported upper and lower trackrails, a hanger-frame secured to the door, and a track-ball confined between said rails and Any required number IOO antifrictionally journaled in said hangerframe, substantially as and for the purpose set forth.

2. A hanger for doors, or the like, comprising aframe having Vertical side pieces separated by a space and joined together hpa web, ball-cups in said vertical side pieces, annular rows of balls in said cups, and a trackball journaled between and uponV said annu- 1o lar rows of balls, substan tially as and. forthe purpose set forth. n
