Year: 1865

page_text: LETTERS PATENT to Charles Horton Williams, of Birmingham, in the
County of Warwick, Manufacturer, for the Invention of "IMPROVEMENTS
IN THE MANUFACTURE OF CORNICE POLE AND OTHER RINGS."
Sealed the 4th July 1865, and dated the 6th April 1865.
PROVISIONAL SPECIFICATION left by the said Charles Horton Williams
at the Office of the Commissioners of Patents, with his Petition, on the
6th April 1865.
I, CHARLES HORTON WILLIAMS, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN THE MANUFACTURE OF CORNICE POLE AND OTHER RINGS," to be
as follows:-
My Invention consists in making cornice pole and other rings from sheet
metal in the manner herein-after explained. I take a strip of metal of the
required width, and by a drawing process of the ordinary kind I give it the
form of a shallow hollow trough or open tube, the sides of the trough or tubo
being parallel or nearly parallel. The said hollow trough or tube may be
plain or have any required ornamental sectional form. I bend and cut the
hollow trough or open tube into ring-like pieces in the way practised in the
ordinary manufacture of cornice pole rings, the concave or hollow part of the
trough or tube being inwards or forming the inside of the ring. I next join
the opposed ends of the rings by brazing. The ends of the rings having been
joined together the parallel sides of the rings are bent or turned inwards, and

page_text: rounded. This bending or turning in and rounding of the sides of the rings is
effected at a lathe. The rings are then finished in the ordinary manner.
Instead of bending inwards and rounding the sides of the trough or open
tube after it has been fashioned into rings, as herein-before described, tho
bending inwards and rounding of the sides of the trough or tube may be
effected by a drawing process or otherwise before the trough or tube is made
into rings. In this case the pieces of open tube have only to be bent into an
annular figure, and the opposed ends brazed to complete the rings, with the
exception of the ordinary finishing process. Instead of making the rounded
edges of the ring by turning the sides of the strip or trough of metal inwards,
the rounding of the edges may be effected by turning the sides of the strip or
trough of metal outwards. The general figure in cross section of the shaped
strip or trough of metal is in this case that of a half tube, with its edges
turned back upon the outer or convex side. By manufacturing cornice pole
and other rings according to my Invention great economy in the quantity of
metal used is secured; the rings are also lighter than ordinary rings, and work
very smoothly.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Horton Williams in the Great Seal Patent Office on
the 30th September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
HORTON WILLIAMS, of Birmingham, in the County of Warwick, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of April, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Horton Williams, Her special licence that I, the said Charles Horton
Williams, my executors, administrators, and assigns, or such others as I,
the said Charles Horton Williams, my executors, administrators, 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, 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 THE MANUFACTURE OF CORNICE POLE AND OTHER RINGS,'
upon the condition (amongst others) that I, the said Charles Horton Williams,
"

page_text: my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 I, the said Charles Horton Williams, 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 thereof, that is to say:―
My Invention consists in making cornice pole and other rings from sheet
metal in the manner herein-after explained. I take a strip of metal of the
required width, and by a drawing process of the ordinary kind I give it the
form of a shallow hollow trough or open tube, the sides of the trough or tube
being parallel or nearly parallel. The said hollow trough or tube may be
plain or have any required ornamental sectional form. I bend and cut the
hollow trough or open tube into ring-like pieces in the way practised in the
ordinary manufacture of cornice pole rings, the concave or hollow part of the
trough or tube being inwards or forming the inside of the ring. I next join.
the opposed ends of the rings by brazing. The ends of the rings having been
joined together, the parallel sides of the rings are bent or turned inwards and
rounded. This bending or turning in and rounding of the sides of the rings is
effected at a lathe. The rings are then finished in the ordinary manner.
Instead of bending inwards and rounding the sides of the trough or open
tube after it has been fashioned into rings, as herein-before described, the
bending inwards and rounding of the sides of the trough or tube may be effected
by a drawing process or otherwise before the trough or tube is made into-
rings. In this case the pieces of open tube have only to be bent into an
annular figure, and the opposed ends brazed to complete the rings, with the
exception of the ordinary finishing process. Instead of making the rounded
edges of the ring by turning the sides of the strip or trough of metal inwards,.
the rounding of the edges may be effected by turning the sides of the strip or
trough of metal outwards. The general figure in cross section of the shaped
strip or trough of metal is in this case that of a half tube with its edges
turned back upon the outer or convex side. By manufacturing cornice pole
and other rings according to my Invention great economy in the quantity of
metal used is secured, and the said rings when in use run or slide much more
smoothly and easily than rings of the ordinary manufacture.
Having explained the nature of my Invention I will proceed to describe

page_text: with reference to the accompanying Drawing the manner in which the same
may be performed.
In making cornice pole or other rings according to my Invention I take a
strip of metal of the required width, and by a drawing process of the ordinary
kind I give the said strip the form represented in Figure 1, that is, the form
of a shallow hollow trough or semi-tube, the sides of the said trough or tube
being nearly parallel. I next bend and cut the hollow trough or tube into
ring-like pieces, in the manner commonly practised in making cornice pole
and other rings, the concave part of the trough or tube being inwards or
forming the inside of the rings; I next join the opposed ends of the rings by
brazing; I finally take the joined rings, and by means of a lathe or other-
wise I bend or turn inwards and round the nearly parallel sides of the trough
as represented in Figure 2, which represents a section of the metal of a
finished ring, the said bent and rounded edges being marked a in the said
Figure 2. The rings are then finished, and where necessary the small loops
or supplementary rings are attached to them in the ordinary way. The hollow
trough or semi-tube may either be plain or have any required ornamental
sectional form.
Figure 3 represents in section a trough or open tube, in which the edges or
sides 6 have been bent inwards and rounded by the drawing process, by which
the trough or tube is made, and Figure 4 represents a plan of a strip of metal
which has been partly drawn of the section of Figure 3, the turned-in and
rounded edges of the trough or strip being marked b. Troughs or open tubes
of the section of Figure 3 are made into rings in the manner herein-before
described with respect to the trough Figure 1, excepting that the bending
inwards and rounding of the edges after the troughs bave been made into
rings is dispensed with. Figure 5 represents a front view, section, and edge
view of a finished cornice pole ring made from a trough or open tube of the
section of Figure 3. Figures 6 and 7 represent sections of troughs or open
tubes in which the rounded edges are bent back upon the outer or convex side
of the trough or tube, instead of being turned inwards as previously described.
The rounded and turned back edges c of the troughs or tubes, Figures 6 and 7,
may either be made by the drawing process by which the trough or open tube
is made, or after the troughs or open tubes have been made into rings, as
herein-before described.
Rings made according to my Invention may have any desired ornamental
section.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not

page_text: limit myself to the precise details herein described, and illustrated in the
Drawing, as the same may be varied without departing from the nature of my
Invention; but I claim as my Invention the improvements in the manufacture
of cornice pole and other rings from sheet metal, herein-before described and
illustrated in the accompanying Drawing, that is to say, manufacturing the
said rings of shallow troughs or open tubes, the concave or hollow part of the
said troughs or tubes being inwards or forming the inside of the rings, the
edges of the said troughs or tubes being bent or turned inwards or outwards,
and rounded either before or after the said troughs or tubes are made into
rings, substantially in the manner described and illustrated.
In witness whereof, I, the said Charles Horton Williams, have hereunto
set my hand and seal, this Twenty-ninth day of September, in the year
of our Lord One thousand eight hundred and sixty-five.
CHARLES HORTON WILLIAMS. (L.S.)
