Petition, on the 22nd April 1861.
IN
We, EDWARD DOUGLAS BOURNE, of Birmingham, in the County of Warwick,
Accountant Clerk, and PAUL DAVIS, of Birmingham aforesaid, Manufacturer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
CERTAIN KINDS OF CORNICE POLES AND CURTAIN RODS, AND IN THE RUNNERS USED
IN CORNICE POLES AND CURTAIN RODS, AND IN THE MANUFACTURE OF TUBING TO
BE MADE INTO THE SAID CORNICE POLES AND CURTAIN RODS," to be as follows:-
Our Invention relates to cornice poles of the kind called grooved cornice
poles and curtain rods of similar construction. The said grooved cornice poles
are commonly made either of a single tube having a slit running its whole length
or of such a tube having a smaller square slit tube in its inside.
In making grooved cornice poles and curtain rods according to our Invention
we make the same of a small slit tube within a larger slit tube, the said small
Price Sd.

page_text: tube being cylindrical in figure and the large tube either cylindrical or semi-
cylindrical, or of the figure of a part of a cylinder greater or less than a semi-
cylinder. We make the said small slit tube either in one piece. with the
larger tube, or attach it thereto by brazing or soldering.
We make the runners used in curtain rods and cornice poles of a cylindrical
or semi-cylindrical figure, the lower end of each runner passing through the
slit of the curtain rod or cornice pole, and being attached to the curtain in the
usual manner.
When we make a grooved cornice pole or curtain rod with its inner small
tube in one piece, we manufacture the tubing of which the cornice pole or
curtain rod is to be made in the following manner:-We draw a plain tube
upon a mandril, having on one side and running its whole length a semi-
cylindrical trough or depression, into which the metal is forced by a rod or tool
placed over the said trough or depression, the whole being drawn through a
draw plate, having in it a guide to maintain the position of the rod or tool.
By a second drawing the trough or depression made in the tube may be closed
so far as to give the whole the figure of a small tube within and excentric to
another, there being a slit or opening running along the double or compound
tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Douglas Bourne and Paul Davis in the Great
Seal Patent Office on the 22nd October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
DOUGLAS BOURNE, of Birmingham, in the County of Warwick, Accountant
Clerk, and PAUL DAVIS, of Birmingham aforesaid, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of April, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fourth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Edward Douglas Bourne and Paul Davis, Her special
licence that we,
Paul Davis
the said Edward Douglas Bourne and
our executors, administrators, and assigns, or such others as we, the said
Edward Douglas Bourne and Paul Davis, our executors, administra-
tors, and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,

page_text: should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN CERTAIN KINDS OF
CORNICE POLES AND CURTAIN RODS, AND IN THE RUNNERS USED IN CORNICE POLES
AND CURTAIN RODS, AND IN THE MANUFACTURE OF TUBING TO BE MADE INTO THE SAID
CORNICE POLES AND CURTAIN RODS," upon the condition (amongst others)
that we, the said Edward Douglas Bourne and Paul Davis, our executors
or administrators, by an instrument in writing under our or their hands
and seals, or under the hand and seal of one of us or them, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Edward Douglas Bourne and Paul
Davis, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement thereof, that is to say:-
Our Invention relates to cornice poles of the kind called grooved cornice
poles, and to curtain rods of similar construction. The said grooved cornice
poles are commonly made of a single tube having a slit running its whole
length, or of such a tube having a smaller square slit tube in its inside.
In making grooved cornice poles and curtain rods according to our Inven-
tion, we make the same of a small slit tube within a larger slit tube, the
said small tube being cylindrical in figure, and the large tube being either
cylindrical or semi-cylindrical, or of the figure of a part of a cylinder greater
or less than a semi-cylinder.
Figures 1, 2 and 3 of the accompanying Drawing represent transverse
sections of cornice poles or curtain rods made according to our Invention.
a, Figure 1, is the small slit cylindrical tube, situated within a larger slit
tube b; the slits of the two tubes coinciding with each other at c. In place of the
large tube b, Figure 1, a hollow semi-cylinder or half tube d may be employed,
as represented in Figure 2. Or a portion of a tube less than a half tube may
be employed in place of the large tube, as represented at e, f; Figure 3. Or
the parts e, f, Figure 3, may be flat or in the same plane. The small tube is
marked a in Figures 1, 2, and 3. The small slit tube a, Figure 1, may either be
in one piece with the larger tube b, or attached thereto by brazing or soldering
or otherwise attached.
When the cornice pole or curtain rod has the figure of a reeded tube, such
as is represented in cross section in Figure 4, the small slit tube may form

page_text: one of the flutes of the said tube, as will be understood by an examination of
the said Figure 4. The small tube g may either be soldered or brazed, or
otherwise attached to the other part of the cornice pole or curtain rod, or be.
fixed to the wood with which the interior of the reeded tube is filled when the
said reeded tube is filled with wood. A small open or slit cylindrical tube,
similar to the tube g, Figure 4, may be attached to a wooden lath, and used as
a curtain lath. A curtain lath of this description is represented in transverse
section in Figure 4 A of the Drawing. The runners by which the curtain is
suspended are situated and work in the small tubes a and g of the cornice
poles or curtain rods, Figures 1, 2, 3, and 4, and in the tube g of the curtain
lath, Figure 4 A; the eye of the runner passing through the slit in the said
tubes a, g, and g³.
We make the runners used in cornice poles and curtain rods of a cylindrical
or semi-cylindrical figure, the lower end of each runner passing through the
slit of the cornice pole or curtain rod, and being attached to the curtain in the
usual manner. Figure 5 represents a cylindrical runner: and Figure 6 a
semi-cylindrical runner made according to our Invention. When we make a
grooved cornice pole or curtain rod and its inner small tube in one piece, as
represented in Figure 1. we manufacture the tubing, of which the cornice pole
or curtain rod is to be made, in the following manner:-We take a plain or
cylindrical tube and place it upon a mandril, having on one side and running
its whole length, a semi-cylindrical trough or depression. A mandril of this
kind is represented in transverse section in Figure 7, the said mandril being
marked, and the semi-cylindrical trough or depression i. The mandril h with
the plain or cylindrical tube upon it is first drawn through a draw plate of the
kind represented in Figure 8, the semi-cylindrical tongue pressing one side
of the tube into the trough or depression i in the said mandril. The tube has
now the figure represented in transverse section in Figure 9. In order to give
the tube, Figure 9, the shape of the cornice pole or curtain rod, Figure 1; it
has to be subjected to another drawing process. This second drawing is
effected by means of the draw plate, Figure 10, which said draw plate has a
circular opening with a notch m on one side. A plug-n having a rib, which
fits in the notch at m of the draw plate, being fixed in the said draw plate;
the tube, Figure 9, upon the mandril is passed through the draw plate,
Figure 10, when the parts o, p, of the tube, Figure 9, are forced into contact
with the plug n, Figure 10, and the tube is made to assume the shape of the
cornice pole or curtain rod, Figure 1. When we make cornice poles and
curtain rods of the forms represented in Figures 2 and 3 we take strips or
sheets of metal, and give them the required form by passing them through

page_text: draw plates, the openings in which have the figures of the cornice poles or
curtain rods, Figures 2 and 3. The openings in the several draw plates which
we employ are bevilled or tapered, as is well understood.
Having now described the nature of our Invention, and the manner in
which the same is to be performed, we wish it to be understood that we do not
limit ourselves to the precise details herein-before described and represented
in the Drawing, as the same may be varied without departing from the nature
of our Invention: but we claim as our Invention,--
Firstly, the improvements in grooved cornice poles and curtain rods, herein-
before described and illustrated in Figures 1. 2. 3. and 4 of the accompanying
Drawing, that is to say, making the said cornice poles and curtain rods of a
small cylindrical slit tube situated within a larger slit tube: also making the
said cornice poles and curtain rods of a small slit cylindrical tube situated
within a hollow semi-cylinder, or a portion of a tube greater or less than a
hollow semi-cylinder: also making the said cornice poles and curtain rods of a
small slit cylindrical tube having a flat plate running on either side of the slit.
as described with reference to Figure 3.
Secondly, making curtain laths of a small cylindrical slit tube attached to a
lath of wood, as herein-before.described and represented in Figure 4 A of the
accompanying Drawing.
Thirdly, making the runners used in grooved cornice poles and curtain rods
of a cylindrical or semi-cylindrical figure. as herein-before described and illus-
trated in Figures 5 and 6 of the accompanying Drawing.
Lastly, the improvement or improvements in the manufacture of tubing to
be made into grooved cornice poles and curtain rods, herein-before described
and illustrated in Figures 7, 8, 9, and 10 of the accompanying Drawing.
In witness whereof, we, the said Edward Douglas Bourne and Paul
Davis, have hereunto set our hands and seals, this Nineteenth day
of October, in the year of our Lord One thousand eight hundred
and sixty-one.
