Improvements in Travelling Hangers for Doors, Gates,
and the like.
I, JAMES THOMAS MCCABE, residing at 160 Huron Street in the City of
Toronto, in the County of York and Province of Ontario, Canada, Builder, do
hereby declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The object of this invention is to provide a frictionless travelling hanger which
can be cheaply and readily manufactured, and by means of which a door or gate
may be properly hung in order that it can be moved in a predetermined direction,
over a predetermined space, with as small au expenditure of applied force as
possible and the invention consists essentially of the device hereinafter set forth
and more particularly pointed out in the claims.
.

Fig. 7 is a sectional view of a third alternative form of hanger.
Like letters of reference refer to like parts throughout the Specifications and
drawings.
It might here be stated, before entering into a description of the construction
shown in the different figs., that the same principle is involved throughout the
different forms of shown constructions, and that the differences existing between the
different constructions are mere changes of form which may be effected in carrying
out the details of construction.
The device shown in Fig. 1 consists of a wheel A having a hub B. The hub B
is fitted with bearing C substantially V-shaped in cross section, upon which run
the balls D. The hanging strap E has a bearing F in the form of a frustum of a
cone, the angle of which corresponds with the angle of the V-shaped bearing C.
Formed centrally through the cone-shaped bearing F is an opening G through
which passes a spindle H having connected to one end a cone-shaped bearing I
corresponding in all particulars with the cone-shaped bearing F. The cone-shaped
bearing I is adjustable either to or from the cone-shaped bearing F, in order that
these bearings can be adjusted to permit of the balls running easily upon them, and
also in order that they can be adjusted to increase or diminish the space between
them to fit as closely as possible the balls, to prevent side motion between the
grooved wheel A and the hanging strap. The spindle H, it will be noticed, is
screw-threaded and is screwed into the cone-shaped bearing F of the hanging strap,
in order that the bearing I may be rigidly secured in its adjusted position and in
relation to the bearing F. The hanger strap E may be of any suitable shape, size
and length, but prefer to so construct the hanging strap E that its lower
extremity will be vertically below the vertical axis of the wheel, in order that
when the door is hung the weight of the door will be evenly distributed on each
The lower end
side of the wheel A, and the rail upon which the said wheel runs.
of the hanging strap E is preferably set within a mortice in the top of the door,
and passing through the door and the hole K in the lower end of the hanging
strap E is a bolt, screw, or rivet by means of which the door is fastened to the

page_text: lower end of the hanging strap. The wheel A is provided with a substantially
V-shaped circumferential groove L, which runs upon a correspondingly shaped
track M. The track M is provided with two or more curved arms N, each having its
concaved side contiguous to the track M, in order that a recess may be formed to
allow of a clearance between the grooved wheel A and the arm, to permit of the
free travel of the grooved wheel along the rail. The upper end of each of the
arms N is bored out to receive the shank O of an adjusting screw P, by means
of which the track is raised or lowered to permit of the attainment of the proper
height of the track for the door, and to permit of the adjustment of the hanger to
allow of the door being made plumb with the frame or jamb. It might here be
stated that these arms serve in the capacity of hangers for the track, and that one
of the arms or hangers is located at the middle of the track, whilst the other
hanger or arm is located at one end of the track. By means of these hangers or
arms any variation of the door frame from shrinkage or other causes can be
rectified, and the track can always be adjusted to hang the door in its proper
relation to its surrounding parts. In the event of any variation in the size of the
bore of the hub the balls can be fitted to the bore by the adjustment of the coned
bearings F and I, that is provided it is necessary to increase the space for the
balls, the coned bearing I can be adjusted from the coned bearing F, and in the
event of the space for the balls requiring to be diminished, the coned bearing I can
be adjusted toward the coned bearing F, in order that the bearing surfaces can be
exactly fitted to the size of the balls to produce an easier and steadier running
wheel. In Figs. 2 and 3 a hanger strap E is employed. It will be noticed by
reference to Fig. 2 of the drawings that the hanger strap E is provided with
two V-shaped bearing surfaces respectively R and S arranged one in either side
face of the hanger strap, and that passing through the hanger strap is a pin or
spindle T. Loosely mounted upon the spindle T are two hemispherical bearing
cases U arranged one on either side of the hanger strap E. Each of the bearing
cases U is provided with an annular V-shaped bearing V corresponding in location,
size, and shape to the adjacent bearing in the side face of the hanger strap E.
Within the annular bearings formed by the bearings in the hanger strap and the
bearing cases are balls D, and it might here be stated that the balls D run within
the bearing cases, and that the bearing cases turn upon said balls, and that in
addition to the bearing cases turning upon said balls the balls support and carry
the hanger strap. The only object of the pin or spindle T is to keep together the
bearing cases and hanger strap, and to hold the several parts in their proper
relation to each other. It might here be stated that two tracks are provided for
the hanger shown in Fig. 2, and upon these tracks run the bearing cases U. Each
of the tracks for the hanger shown in Figs. 2, 3, and 7 are similar in construction
to the track shown in Fig. 1. In Fig. 3 the hanger is shown to consist of a hanger
strap E, at its upper end provided with a bearing C substantially V-shaped in
cross section (similar to the bearing C shown in Fig. 1 of the drawings). Upon
the bearing C run the balls D. Located one on either side of the hanger strap E,
and in juxta position to the bearings C, at the upper end of the hanger strap E,
is a hemispherical bearing case U. Each of the bearing cases U is provided with
a bearing in the form of a frustum of a cone, the angle of which is equal to the
angle of the V-shaped bearing C, and this cone-shaped bearing is arranged to
complete the bearings for the balls D. Passing through the bearing cases U is a
pin or spindle T having each end upset against the outer side of the bearing cases.
The object of the pin or spindle T is to hold together the several parts, namely,
the bearing cases and the hanger strap, and keep them in their proper relation to
each other. In Fig. 7 I have shown a construction similar to that shown in Fig. 3,
with the exception that the pin or spindle T is screw-threaded, and the cone-shaped
bearings and the bearing cases U are screwed on the pin or spindle T into their
proper position. A nut W is screwed on each end of the pin or spindle T, and
against its respective bearing case U, for which it forms a lock and prevents the
travel of the hanger unscrewing the bearing cases from the pin or spindle. As

page_text: shown in Fig. 7 the foot or end of the hanger strap is enlarged, and this end may
be of any suitable shape and size. I prefer however to make the foot X of the
hanger strap circular shaped and bevelled, in order that it can enter a corre-
spondingly shaped recess in the plate Y, which is securely fastened to the top of
the door by means of screws. The object of making the foot X of a circular form
is to permit of the union of this circular shaped foot and the plate Y forming a
swivel to permit of the hanger turning a curve without binding on the track.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I hereby declare that
what I claim is :
1. The travelling hanger herein before described and illustrated in Fig. 1 of the
