,new and useful Improvements in Silding-Door Tracks and Hangers, of which the following isa specification.

This invention relates to sliding-door tracks and hangers; and its objects are, first, to produce a noiseless track and means for vertically adjusting the same; second, to provide means'for disconnecting a hanger from the top of a door without disturbing its ver-- tically-adjusting mechanism, and, third, to afiord means for vertically adjusting a hanger by lengthening or shortening it without disconnecting it from its door.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of a sliding-door track and hangers embodying my improvements. Fig. 2 is an end view of the same. Fig. 3 is a detailed end view of one rail of the track and its supporting-trough. Fig. 4 is an isometri'oal'detail'of a fragment of the railsupporting troughs of the track, a screw for adj ustably connecting such troughs with their soflit, and a front door-stop. Fig. 5 is an isometric detail of devices for supporting unadjustably one end, as S, of the track. Fig.

6 is an isometric detail of two fragments of the connecting-webs'of the Tail-supporting troughs and aslightly-yielding joint connecting their adjacent ends together. Fig.7.is an isometrical detail of a complete, hanger minus its wheelsgthe wheel-frame being disconnected from the otherparts thereof. Fig. 8 is an isometric detail of the parts unassembled composing the hanger shown in Fig. 7- minus the wheel-frame. Fig. 9 is a detail of the parts of the hanger shown in Fig. 2. Like letters of reference indicate corresponding parts throughout the several views. 45

A represents parallel metal troughs connected by a supporting-web A and are preferably integral. 1

B represents preferably continuous rails of wood or fibrousunaterial resting in and supported by the troughs A and projecting above the edges thereof to prevent the hangerwheels from coming in contact therewith.

O is any suitable non-conducting or sounddeadening material, as felt or. the like, interposed in sheet form between the rails B and the inner surfaces of the'troughs A.

D is a soffit provided with downwardly-projecting lugs D, having threaded screw-holes extending vertically upward therethrough to receive screws, referred to hereinafter.

E, Figs. 1 and 6, is a semitoggle-joint connection between the adjacent but non-contiguous ends of the two pairs of troughs A, formed by means of a metal strap E, rigidly secured into the interior of one of. the supporting-websA of such troughs by means of rivets E extending therethrough and yield- F represents screws for suspending and ver-v I tically adjusting the completed track, Figs. 1 and 2. Each of these screws, Fig. 4., has formed thereon an annular shoulder F adapted to engage the retaining-lip F on the web A, which retaining-lip F and screw-head F insure vertical adjustment of the track by turning the screw F up-or down, as may be required. V

G is a door-stop secured to the bottom of the troughs A by means of screws G, provided with a rubber buffer G and rendered longitudinally adjustable by the longitudinal slots G3 therein.

H is a track-suspending loop secured to and depending from the under side of the soifit D.

H" is an L-shaped suspending-lug having its vertical arm H secured to the web A of the troughs A and its horizontal arm H inserted into the loop H.

I is a base-plate having horizontal slideways I' l thereon, the latter also having a longitudinal slot I in the top thereof to admit a part to be described hereinafter.
