Improvements in Jointed Metallic Cornice Poles and Rods.
We TONKS LIMITED of Moseley Street Birmingham in the County of Warwick
Manufacturers and WILLIAM HENRY TONKS the younger, Director of Tonks
Limited aforesaid do hereby declare the nature of this invention to be as
follows:
:-
The said invention has reference to such jointed metallic cornice poles and rods
as are provided with movable or adjustable ends or parts to fit the angles or recess
of the window or portion of the room to which the cornice pole or rod is fitted or
applied; and the said invention consists of the construction and combination of
parts hereinafter described constituting an improved joint for jointing the movable
ends or parts of the cornice pole or rod to the middle part for permitting of the
accurate adjustment of the said movable ends or parts to the angles or recess of
the window or part of the room to which the pole or rod is to be applied.
We will describe the said invention as applied to the jointing of the movable
ends of a cornice pole to the middle or straight part of the pole.
For connecting the said ends of the tubular cornice pole to the middle or
straight part, we use a junction piece consisting of a hollow ellipsoid to which the
ends of the parts of the pole to be connected are jointed, the joints being formed
by pins or axes situated respectively on each side.of and at a short distance from
the plane in which the shorter axis of the cllipsoid is situated. The ends of the
two parts of the pole to be jointed to the ellipsoidal junction piece are bevilled on
each side of the joint pin, the said bevilled parts on each side of the joint part of
the pole forming a right angle with cach other.
By this construction of joint, the jointed end of the pole can be inclined to the
fixed or straight part of the pole at any angle between a right angle and a straight
line, the continuity of the two parts of the pole being unbroken or without
angle in any position of the end piece; hence, rings of the diameter proper for
sliding on the pole or rod can pass without obstruction the jointed parts of the pole
or rod.
Joints of the construction described may be introduced at any part or parts of
the cornice pole or rod which requires or require to be at an angle with the adjacent
part or parts.

Improvements in Jointed Metallic Cornice Poles and Rods.
We TONKS LIMITED, of Moseley Street, Birmingham in the County of
Warwick, Manufacturers and WILLIAM HENRY TONKS the younger Director of
Tonks Limited, aforesaid, do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The said invention has reference to such jointed metallic cornice poles and rods
as are provided with movable or adjustable ends or parts to fit the angles or recess
of the window or portion of the room to which the cornice pole or rod is fitted or
applied; and the said invention consists of the construction and combination of
parts hereinafter described constituting an improved joint for jointing the movable
[Price 8d1

page_text: ends or parts of the cornice pore or rod to the middle part for permitting of the
accurate adjustment of the said movable ends or parts to the angles or recess of
the window or part of the room to which the pole or rod is to be applied.
We will describe the said invention as applied to the jointing of the moveable
ends of a cornice pole to the middle or straight part of the pole.
For connecting the said ends of the tubular cornice pole to the middle or straight
part, we use a junction piece consisting of a hollow ellipsoid to which the ends of
the parts of the pole to be connected are jointed, the joints being formed by pins
or axes situated respectively on each side of and at a short distance from the plane
in which the shorter axis of the ellipsoid is situated. The ends of the two parts
of the pole to be jointed to the ellipsoidal junction piece are bevilled on each side
of the joint pin the said bevilled parts on each side of the joint part of the pole
forming a right angle with each other.
By this construction of joint the jointed end of the pole can be inclined to the
fixed or straight part of the pole at any angle between a right angle and a straight
line, the continuity of the two parts of the pole being unbroken or without angle
in any position of the end piece; hence, rings of the diameter proper for sliding
on the pole or rod can pass without obstruction, the jointed parts of the pole
or rod.
Joints of the construction described, may be introduced at any part or parts of
the cornice pole or rod which requires or require to be at an angle with the adjacent
part or parts.
Figure 1 of the accompanying drawing represents in plan, a jointed metallic
cornice pole or rod to which joints constructed according to this invention are
applied;.
Figure 2 represents in elevation and Figure 3 in vertical section, a portion of the
cornice pole or rod drawn to a larger scale;
Figure 4 represents the joint parts of Figure 2 detached and
Figure 5 represents in plan the middle part of the pole jointed to the junction
piece and one of the end parts of the pole in section and detached from the junction
piece;
Figure 6 represents the same view as Figure 5 with the two parts of the pole or
rod jointed to the junction piece.
The same letters of reference indicate the same parts in the several figures of the
drawing.
a is the middle tubular part of the metallic cornice pole or rod and b, bare the
movable tubular ends of the same, the said end parts being connected to the middle
part a by the hollow ellipsoidal junction piece c and the parallel joint pins or
axes d, d, the said pins or axes d, d being situated respectively on each side of and
at a short distance from the plane in which the shorter axis of the ellipsoidal
junction piece c is situated as best seen in Figures 2 and 3. The inner or jointed
ends of the two parts b, 6 of the cornice pole or rod are bevilled at e on each side
of the joint pin d as best seen in Figures 5 and 6, the said bevilled parts e on either
side the joint pin d forming a right angle with each other. The joint pins or
axes d, d consist of headed and screwed pins which are passed through holes made at
the junction of the bevilled parts e of the pole ends b, band also through holes
made in the hollow ellipsoidal junction piece c, and the said pins or axes are
fastened in their places on the underside of the pole by screw nuts at d², d² as seen
in Figures 2 and 3. In place of screw pins and screw nuts, rivets may be used for
forming the pins or axes of the joint. The end parts b, b of the cornice pole or rod
thus jointed to the middle part a by the ellipsoidal junction piece c and vertical
parallel pins or axes d, d can be inclined at the angle represented to the middle
part a shown in Figure 1, or at either of the angles indicated in dotted lines in the
said Figure 1; or the said end parts may make any angle not exceeding a right
angle with the middle part.
When the end parts b, b of the cornice pole or rod are inclined or placed at any
desired angle with respect to the middle part a their continuity with the middle

page_text: part of the cornice pole is unbroken or is without angle and the curtain rings
having the diameter proper for freely sliding on the pole or rod can pass without
sensible obstruction the jointed parts of the pole or rod as will be understood by an
examination of Figure 1.
It is preferred to make the hollow ellipsoidal junction piece c by core casting,
but the said junction piece may be otherwise made. For example, it may be made
in halves by stamping and spinning and the halves joined edge to edge by brazing į
or the end portions of the junction piece may be made by stamping and spinning and
joined together by casting between their edges a middle band, or brazing a middle
band between them, the said band having cast or made in it the holes through
which the joint pins or axes pass.
Although we have represented a cornice pole or rod of the simplest kind, that is,
consisting of a middle part and two jointed end parts yet we wish it to be under-
stood that our improved joints may be introduced at any part or parts of the cornice
pole or rod which require to be at an angle with the adjacent part or parts as
before stated.
Having now particularly described and ascertained the nature of the said inven-
tion and the manner in which the same is to be performed we declare that we claim
as the said invention of "Improvements in jointed metallic cornice poles and
rods":-
Jointing the movable parts of tubular metallic cornice poles and rods by means
of ellipsoidal junction pieces to which the ends of the movable parts are jointed by
parallel pins or axes situated respectively on each side of and at a short distance
from the plane in which the shorter axis of the said ellipsoidal junction pieces is
situated, the inner or joint parts of the ends of the pole or rod to be jointed to the
junction piece being bevilled on each side of the joint pin, the bevilled parts
forming a right angle with each other substantially as herein before described and
illustrated in the accompanying drawing.
