Improvements in the Joints of Cornice Poles and the like.
I, WILLIAM ALFRED BIBB, of Dora Road, Small Heath, in the City of
Birmingham, Brassfounder, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the joints of cornice poles, curtain rods and other
articles of a kindred nature, the sections of which are required to make angles
relative to one another in order to fit within a window or other recess, and my
said invention has for its object, the production of a simple and efficient joint which
may be made from sheet or other metal and thereby considerably reducing the cost
of manufacture.
A joint constructed according to my invention consists of two diagonally divided
hemispherical halves or segments, respectively attached by screws to the opposed
ends of two adjacent sections, of a cornice pole, and with the metal at the diagonal
edge of the one half or shell being spun or turned over or otherwise connected to
the diagonal edge of the other half, so that the said halves of the joint can be
turned upon one another when the pole sections to which they are attached are
placed to an angle relative to each other or when such an angle between the
sections is changed.
In carrying out my invention, I take two diagonally faced or edged hemispherical
shells, united together to form a complete sphere but turning upon one another at
their diagonal edges, the joint between which may be strengthened by an interposed
joint. Each half shell has a shank or socket and a screw or other attachment for
securing the same to a pole end.
When the sections of the pole are in a horizontal plane then the shank or
connection of one half of the joint is lignable with that of the other, but by rotating
one shell or half upon the other shell or half, the connection ends are brought to an
angle as may be required.
In joints made from cast metal, I make the diagonal faces of the half rolls with
flanges and connect the same together by spinning or closing a metal ring over
them so that the diagonal edge of the one hemisphere will work over the like edge
of the other hemisphere and by the turning the one hemisphere or the other the
shanks of them are made to change their relative angles.
Dated this 27th day of April 1896.

I, WILLIAM ALFRED BIBB of Dora Road, Small Heath in the City of
Birmingham, Brassfounder, 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 :-
This invention relates to the joints of cornice poles, curtain rods and other
articles of a kindred nature, the sections of which are required to make angles
relative to one another in order to fit within a window or other recess, and my
said invention has for its object, the production of a simple and efficient pin-less
joint which may be made from sheet or other metal and thereby considerably
reduce the cost of manufacture.
A joint constructed according to my invention consists of two diagonally divided
hemispherical halves or segments, respectively attached by screws to the opposed
ends of two adjacent sections of a cornice pole, and with the metal at the diagonal
edge of the one half or shell being spun or turned over or otherwise connected to
the diagonal edge of the other half, so that the said halves of the joint can be
turned upon one another when the pole sections to which they are attached are
placed to an angle relative to each other or when such an angle between the sections
is changed.
In carrying out my invention, 1 take two diagonally faced or edged hemispherical
shells, united together to form a complete sphere but turning upon one another at
their diagonal edges, the joint between which may be strengthened by an interposed
disc. Each half shell has a shank or socket and a screw or other attachment for
securing the same to a pole end.
When the sections of the pole are in a horizontal plane then the shank or
connection of one half of the joint is lignable with that of the other, but by rotating
one shell or half upon the other shell or half, the connection ends are brought to
any angle as may be required.
In joints made from cast metal, I make the diagonal faces of the half shells with
flanges and connect the same together by spinning or closing a metal ring over
them so that the diagonal edge of the one hemisphere will work over the like edge
of the other hemisphere and by the turuing the one hemisphere or the other the
shanks of thein are made to change their relative angles.
As a modification, the meeting edges of the hemispheres may be directed in a
horizontal plane instead of obliquely. In such a case then the shanks have
respectively clearances to allow for the horizontal movement of the half spheres one
upon.another.
Figure 1 of the accompanying drawings represents a view, upon a small scale, of
a cornice pole fitted with my improved pin-less joints.
Figure 2 is a topside plan of one of the joints separately, upon an enlarged
scale.
Figure 3 represents a like view as Figure 2, but with the sections of the joint in
positions relatively at right angles to one another.
Figure 4 is a side elevation of Figure 2, and Figure 5 represents a vertical
section of Figure 2 upon the dotted line z.
Figure 6 represents, partly in section and partly in elevation, the parts of the
joints separately.
Figure 7 represents upon a further enlarged scale, a like view as Figure 5.
Figure 8 represents partly in elevation and partly in section, a modified form of
joint in which the segments are made of cast metal with the flanged edges connected
by a spun sheet metal ring.

page_text: Figure 9 represents a like view of the modification in which the meeting edges.
of the sections of the joint are in a horizontal plane.
In Figures 1 to 7, a, a' are two hemispherical shells or hollow segments, with
their meeting edges a, a, disposed in an oblique plane and united together by the
boundary elges a', of the one part being taken over the beaded edges a', of the
other, hence the formation of a pin-less joint and the connection of the halves
together without the employment of a cross pin, rivet or like expedient.
bis a disc, diaphragm or internal stay for diametrically supporting the shells at
their outer edges or at the part where the joint comes.
c is the shank of one shell a, which has an attachment screw d, designed to take
into either wood or metal and e is an internal supporting disc for the said shank.
The shell a¹ is also provided with a like shank, shell and supporting disc c', d'
and e'.
Instead of employing screws such as d, d', the shanks c, c', may be extended into
sockets adapted to take onto the ends of a pole and be there secured by small screws
or otherwise.
Instead of the hemispheres being connected together by turning the edge of the
one over the beaded edge of the other, the said edges may be formed into outwardly
directed ring flanges, which are connected together by a spun-on ring or equatorial
band.
In Figure 8, a, a¹ are the cast metal segments, respectively provided with
shanks c, c¹, and attachment screws d, d', and with the edges of the opposed faces
having flanges or beadings a³, a³, connected together by a spun-over ring or
equatorial band of sheet metal aº.
In Figure 9, a, a' are the segments of the joint, which are shown as made of cast
metal and provided with shanks c, c', and attachment screws d, d', whilst the
horizontal meeting faces have flanged edges a³, a', connected together by a spun-on
ring or annular band of sheet metal a. a, a, are clearances for the meeting edges
of the opposed sections to the joint to admit of the one part working horizontally
upon the other.
In adjusting the sections of a pole, the axes of the same are taken slightly out of
the horizontal plane, and to bring them back again, it is necessary to give one of
the sections a slight twist or turn.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
First. A pin-less joint for cornice poles, curtain rods and the like, consisting of
two diagonally or obliquely divided hemispherical parts or segments with the
meeting edges united or coupled together in such a manner as to admit of the one
part turning or working upon the other for the purpose herein set forth.
Secondly. A pin-less joint for cornice poles, curtain rods and the like, consisting
of two horizontally divided hemispherical segments with their meeting edges united
together in such a manner as to admit of the one part turning or working upon the
other for the purpose herein set forth.
Thirdly. The improvements in the construction of cornice pole and other like
joints, substantially as herein described and set forth.
