A NEW OR IMPROVED MANUFACTURE OF ORNAMENTAL METALLIC TUBES
Year: 1856

page_text: LETTERS PATENT to William Bayliss, of Birmingham, in the County of;
Warwick, Tube Maker, for the Invention of "A NEW OR IMPROVED
MANUFACTURE OF ORNAMENTAL METALLIC TUBES."
Scaled the 18th November 1856, and dated the 11th June 1856.
PROVISIONAL SPECIFICATION left by the said William Bayliss at the
Office of the Commissioners of Patents, with his Petition, on the
11th June 1856.
I, WILLIAM BAYLISS, of Birmingham, in the County of Warwick, Tube;
Maker, do hereby declare the nature of the said Invention for "A NEW OR.
IMPROVED MANUFACTURE OF ORNAMENTAL METALLIC TUBES," to be as follows,:-
My Invention consists in the manufacture of ornamental metallic tubes, by
pressing a plain tube upon a mandril having upon it the ornamental figure to
be given to the tube, the said pressure being applied as herein-after described.
In carrying my Invention into effect I proceed as follows:-In making.
a twisted tube, I place a plain tube upon a twisted mandril, and placing the
said mandril in a lathe, communicate thereto a slow rotatory motion; a tool,
something like a cutter, but blunt. at its end, is fixed in the slide rest of
the lathe, and is made to advance from end to end of the tube during its
rotation. The tool described presses the tube into contact with the mandril in
its interior.
My Invention is applicable to taper tubes of the same diameter throughout,
and to the production of other patterns than the twisted pattern described.

by the said William Bayliss. in the Great Seal Patent Office on the
4th December 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BAYLISS, of Birmingham, in the County of Warwick, Tube Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of. June, in the year of our Lord One
thousand eight hundred and fifty-six, in the nineteenth year of Her reign, did,
for Herself, Her heirs and successors, give and-grant unto me, the said William
Bayliss, Her special licence that I, the said William Bayliss, my executors,
administrators, and assigns, or such others as I, the said William Bayliss, 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 terni
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 "A NEW OR IMPROVED MANUFACTURE
OF ORNAMENTAL METALLIC TUBES," upon the condition (amongst others) that I,
the said William Bayliss, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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 I, the said William Bayliss, 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 of manufacturing ornamental metallic tubes by
pressing a plain tube into 'contact with a mandril, the said mandril having
upon it the ornamental figure to be given to the tube, the pressure being
applied as herein-after described.
*
My Invention is applicable to the manufacture of taper tubes, having
convex or concave flutes situated in the same planes as the axis of the tube, or
passing spirally round the said tube.
In carrying my Invention into effect I place a plain taper tube upon a
twisted mandril; I place the said mandril and tube in a lathe, such as is used
for cutting screws, and communicate to the said tube and mandril a rotatory

page_text: motion. A tool is fixed in the slide rest of the lathe, and is carried from end
to end of the tube during its rotation, the said tool moving as the cutting tool
moves in a screw-cutting lathe. The end of the said tool is formed so as to fit
the bottom of the twisted flute, whether the said flute be convex or concave.
The said tool presses the tube into contact with the mandril in its interior, and
communicates to the said tube the figure of the said mandril. The tube may
be removed from the mandril by unscrewing it therefrom. When the flutes to
be made in the tube are not twisted, then no rotatory motion is communicated
to the mandril, but the tube placed upon the mandril is pressed into contact
with the said mandril by a suitably shaped tool. The said tool is pressed upon
the tube either by hand or by being placed in the slide rest of a lathe; or
the tube and mandril may be fixed on the bed of a planing machine, and the
pressing tool fixed in the place of the cutter in the planing machine. By
carrying the tube and mandril under the tool, as in working the ordinary
planing machine, the tube may be pressed into contact with the mandril. The
tube and mandril are made partially to rotate from time to time, so as to bring
those portions of the tube which have not been previously acted upon under
the operation of the pressing tool.
My Invention is applicable especially to the manufacture of taper tubes, as
there is difficulty in removing the tube from the mandril if the mandril is of
uniform diameter throughout. The tube, however, may be removed from
a mandril of uniform diameter by heating the said tube suddenly, and thereby
expanding the same.
IIaving now described the nature of my said Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein described, as the same may be varied
without departing from the nature of my said Invention; but I claim as my
Invention manufacturing ornamental metallic tubes, by pressing a plain tube
upon a mandril having upon it the ornamental figure to be given to the tube,
the said ornamental figure being such as will permit of the withdrawal of the
mandril from the tube.
In witness whereof, I, the' said William Bayliss, have hereunto set my
hand and seal, this Third day of December, in the year of our Lord
One thousand night hundred and fifty-six
Witness,
WILLIAM BAYLISS. (L.S.)
