Improvements in and in the Manufacture of Joints for Cornice Poles
and analogous Articles.
I, WILLIAM ALFRED BIBD, of 28, Dora Road, Small Heath, in the City of
Birmingham, Commercial Traveller, do hereby declare the nature of this inven-
tion to be as follows:--
This invention has relation to the joints employed for connecting together
the parts of cornice poles, curtain rods and analogous articles and particularly
to joints of that class made up of two sheet metal-hemispheres connected so as to
admit of turning upon one another by turning the edges of the one over the
edges of the other with a sliding fit, the said hemispheres being respectively
attached to the meeting ends of two lengths of a pole or rod to be connected,
by screws carried by them taking into the said pole or rod ends.
The objects of my present invention are to obviate the necessity of attaching
the fixing screws to the hemispheres of the joint and to provide a stronger and
improved article in which the joint between the two parts is straight, or in the
same horizontal plane as the connected rod lengths.
In carrying out my invention the body of the joint consists of two hemi-
spheres, each formed from sheet metal and having straight edges, one of the said
edges being formed into an annular tongue and over which the edges of the
other hemisphere are turned loosely, so as to admit of the one part having a free
tuning movement upon the other in a horizontal plane. This circumferential
joint makes an annular beading around the ball, and a mount or pummel, prefer-
ably made from sheet metal, is secured to each half for the attachment of the
affixing screw thereto.
Each mount may consist of a cup shaped fitting having a closed end which is
concaved to conform to the curvature of the sphere and has gaps at opposite
points to form clearances for the annular beading of the joint to move within.
They are attached respectively to the halves of the sphere preferably by running
solder through a gap or holes in the closed end of the mount, so arranged that
the one hole comes above the beading on the one side of the sphere and the other
below the said beading on the other sphere.
The screws may have square shanks which are rivetted or otherwise connected
to stout metal discs (dished or corrugated to give strength) which are placed up
to annular shoulders at the open ends of the mounts or pummels and then
secured by turning or closing over their own edges, the metal at the edges of
the said pummels.
Instead of employing affixing pins secured in this manner to the pummels,
they may be dispensed with and the said pummels, after being suitably reinforced
if necessary may be crease-wormed to screw onto the end of a wooden pole.

page_text: Other suitable means may be employed in lieu of soldering, for securing the
mounts or pummels respectively to the halves of the sheet metal ball joint.
Dated this 9th day of November 1809.

Improvements in and in the Manufacture of Joints for Cornice Poles
and analogous Articles.
I, WILLIAM ALFRED BIBB, of 28, Dora Road, Small Heath, in the City of
Birmingham, Commercial Traveller, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :- -
This invention has relation to the joints employed for connecting together
the parts of cornice poles, curtain rods and analogous articles. The present
invention, which is an improvement upon, or an amplification or development of
the invention described in the Specification of a previous Letters Patent granted
to me and bearing date the 28th day of April 1896 No. 8891, has particular
reference to joints of that class in which two sheet-metal hemispheres are con-
nected in such a manuer as to admit of rotating upon one another by turning
the edges of the one over the edges of the other with a sliding fit, the said hemi-
spheres being respectively attached to the meeting ends of two lengths of a pole
or rod to be connected, by screws carried by them taking into the said pole or
rod ends.
The objects of my present invention are to obviate the necessity of attaching
the fixing screws to the hemispheres of the joint and to provide a stronger and
improved article in which the joint between the two parts is straight, or in the
same horizontal plane as the connected rod lengths.
Figure of the accompanying drawings represents a plan of a pin-less cornice-
pole joint constructed or made up in accordance with the present invention.
Figure 2 represents another plan of the joint but shows the one member of tho
same turned into a position at right angles to the other member.
Figure 3 shows a complete longitudinal section of the said joint upon the
dotted line r Figure 2.
Figure is a sectional view of the several component parts from which this
joint is made up, dis-assembled from one another.
Figure 5 is an elevation of the two halves of the joint, showing the hemi-
spheres with their respective mounts or pummels sepainted, it being understood
that this view is only a diagramatic one to show the relationship between the
parts and that the component elements are not actually assembled in this manner
in the process of manufacture.
Figures 6 and 7 respectively represent elevations of the opposed ends of the
pummels or mounts of the joint, whilst
Figure 8 shows a section and Figure 9 a plan of the spherical part of the joint,
which is composed of two hemispherical and horizontally divided shells working
one upon the other.
The same letters of reference indicate corresponding parts in the several
figures of the drawings.
In carrying out my invention the body a, of the joint consists of two hemi-
spheres b, c, each formed from sheet metal and having straight edges b', c', which

page_text: lie in a horizontal plane when the joint is in use. One of the said edges b₁ is.
formed into an annular tongue or ib, over which the edge c', of the socketted
mouth, of the other hemisphere is turned loosely, so as to connect the two
shells together but still admit of the one part having a free turning movement
upon the other in a horizontal plane. This circumferential joint makes au
annular beading around the ball, to each half of which a separate mount or
pummel d, e, preferably made from sheet metal is secured for effecting the
attachment of the affixing screw thereto.
Each of these mounts d, e may consist of a cup shaped fitting having a closed
end d, e, which is concaved to conform to the curvature of the sphere and has
opposite sinkings,, to form clearances for the annular beading of the joint
to move within. They are attached to their respective halves of the sphere
preferably by running solder (marked f) through gaps or holes d, e, in the
closed seating ends of the mounts, so arranged that the one hole comes above
the beading on the one side of the sphere and the other below the said beading
on the other sphere, as clearly shown in Figures 3, 4, 6 and 7.
The attachment screws g, may have square or angular shanks g', which are
rivetted or otherwise rigidly connected to siout metal discs dished or corru-
gated (if desired to give strength) which are placed up to annular shoulders d', et
at the open ends of the mounts or pummels and then secured by turning or closing
over their own edges, the metal at the edges of the said pummels.
Instead of securing the discs plates or carries of the attachment screws to the
sheet metal mounts by turning the metal of the one over that of the other as
described, they may be affixed by soldering, screwing or otherwise, whilst instead
of employing affixing pins secured in this manner to the pummels, they may be
dispensed with and the said pummels, after being suitably reinforced if necessary,
may be crease-wormed to screw onto the end of a wooden pole.
Other suitable means, such as screw pins and nuts may be employed in lieu
of soldering, for securing the mounts or pummels to the respective halves of
the sheet metal ball joint, and I do not confine myself to the particular menus
of herein described for connecting together the respective hemispheres of the joint,
so long as they admit of turning or rotating about one another.
It is understood that in making up this joint, the two sections of the hemi-
sphere are first connected to one another, then the mounts or pummels are soldered
or otherwise attached to their respective halves, and finally the discs carrying
the attachment are secured to the pummel.
It is obvious that my improved method of securing the attachment screws to
the mounts or pummels is applicable to joints in which the rotating hemispheres
are connected by pins or pivots, and also to cornice pole and analogous joints
of the type described in the Specification of my Letters Patent dated the 26th day
of April 1897 No. 10296.
Figure 10 represents a section of one such application, being a part of the
joint, e the sheet metal mount or pummel and h the carrier disc of the attach-
ment screw g.
It is also obvious that the method herein described of connecting the sections
of the sphere to their respective pummels or screw-carrying mounts is applicable
to ioints of the diagonal type as described and represented in my before-referred
to Letters Patent No. 8891 of 1896. Figure 11 is a sectional view showing this
application be. heing the sections of the ball, the diagonal joint between
them and d. e the screw-carrying mounts, which are attached to their respective
sections of the sphere by screw solder at f, or by pins, rivets or equivalent means.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
First In cornice pole and analogous joints having sheet metal mounts or
pummels; connecting the attachment screws through the medium of plates or

page_text: carriers, which are secured within the mounts, or within the open ends of the
mounts, substantially as herein described and also as set forth in the acconi-
panying drawings.
Secondly: The manufacture of pin-less sheet metal ball-joints for cornice
poles and analogous articles, from two sheet metal hemispheres, rotatably con-
nected to one another, with the joint between them disposed either horizontally
or obliquely, and each being fixed or attached to a sheet metal or shell mount,
pummel or pole-end cap, substantially as herein described, and also as set forth
in the accompanying drawings.
Thirdly The manufacture of pin-less sheet metal ball-joints for cornice
poles and analogous articles, from two sheet metal hemispheres, rotatably con-
nected to one another, with the joint between them disposed either horizontally
or obliquely, and ench being fixed or attached to a sheet metal or shell mount, to
which the attachment screws are affixed through the medium of plates or carriers,
substantially as herein described, and also as set forth in the accompanying
drawings.
