Figure 2, a front elevation;
Figure 3, a top elevation, and
Figure 4, a perspective view of the anti-friction roller.
A represents the base of the hanger, secured by screws or in any well known
manner to the top of the door B. At one end of said base is an upright standard or
arm C, cut away at e to allow of its free passage along the trackway.
Hinged to the upright arm (1 is a swinging lever or arm D, having an opening or
slot formed in its forward end.
On the rear side of this swinging lever or arm and along the slot d is secured
a bracket E, having its lower end extended and turned upward at e to form a guide
for the track-rail support and a bearing for a small wheel G, which abuts against the
lower edge of the track-rail and its support to prevent the track-wheel from jumping
the track.
Within the opening or slot d in the forward end of the swinging lever or arm D is
a large track-wheel F, having a groove fin its periphery, in which the track-wheel
runs, the shaft of which passes through the swinging arm D and the bracket E.
In the forward end of the swinging lever or arm D and in front of the slot d is
another opening d', through which a metal rod H, having screw-threads at each
end, passes.
The rod H is bent at 7, as shown, to allow of its free passage along the track-
way. One end of said rod passes through the base A of the hanger down into the
door B, where it passes through a guide-lug k on a countersunk plate K in the edge
of the door B, and is secured by a milled nut m. One side of this milled nut m passes
through an opening in the front of the countersunk plate K for the purpose herein-
after described. On the other or upper end of rod is a nut M, for adjusting the
door to its working position when first hung upon the track.
Irstead of this nut M a groove can be cut in the rod H and a set-screw inserted
through the swinging lever or arm D, if desired. An anti-friction roller, composed of
a base P, roller p, and shaft r, is secured to the floor at a point near the rear of the
door B, which works in the groove s in the lower edge of the door, and the doors are
prevented from running too far forward by a stop R.

page_text: The operation is as follows: The door having been secured to the base of the
banger, the groove in the track-wheel Fis place upon the track-rail O, secured to its
support. The door now being suspended in position upon the track, it is adjusted to
the proper working position by monns of the swinging levor or arm 1, metal rod H,
and the nut M, when it can be moved forward and backward.
As soon as the door sags and refuses to operate, the milled nut m, projecting through
the countersunk plate K, is turned, which causes the door to be raised to its proper
working position again, when it will operate freely. It will be seen that by this
arrangement doors can be raised or lowered after they have become sagged and
inoperative without removing any portion of the door or studding, as the milled nut
projecting through the countersunk plate is always accessible. It will also be noted
that the metal rod I assists the upright arm or standard C in suspending the track-
wheel F, and that hy this construction only a half-inch space is required between the
head-jaws.
I have described my invention as applicable to doors only; but it is obvious that it
may be applied to windows and blinds as well.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the samo is to be performed, 1 declare that what I
claim is:
1. In a door-hanger, the combination of a track-rail, a base-plate secured to the top of
the door, a standard on said lase-plate an arm hinged at one end to said standard, n
bracket secured to said arm, wheels on the arm and bracket for contact, respectively,
with the upper and lower edges of said track-rail, a supporting-bar at the outer or free
end of said arm, and adjusting mechanism on said supporting-bar for effecting the
vertical adjustment of the door substantially as shown and described.
2. In a door-hanger, the combination of a track-rail, a base-plate secured to the top
of the door, a standard on said base-plate, an arm hinged at one end to said standard, a
bracket secured to said arm, wheels on the arm and bracket for contact, respectively,
with the upper and lower edges of said track-rail, a supporting-bar at the outer or free
end of said arm, and separate adjusting mechani-in at the top and lower ends of said
supporting-bar for effecting the vertical adjustment of the door substantially as shown
and described.
