LETTERS PATENT to William Pitt and Edward. Turner Davies, of
Birmingham, in the County of Warwick, Brassfounders, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF CORNICE POLES AND
PICTURE RODS, AND IN RINGS AND CHAINS.. TO BE USED IN. CONNECTION
THERE WITH."
COMPLETE SPECIFICATION filed by the said William Pitt and Edward
Turner Davies at the Office of the Commissioners of Patents, with their
Petition and Declaration, on the 22nd August 1855, pursuant to the
9th Section of the Patent Law Amendment Act, 1852.
We, WILLIAM PITT and EDWARD TURNER DAVIES, of Birmingham, in the
County of Warwick, Brassfounders, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF CORNICE POLES AND
PICTURE RODS, AND IN RINGS AND CHAINS TO BE USED IN CONNECTION THEREWITH,"
and the manner in which the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to say:―
Our Invention has for its object the manufacture of the above-named
articles on a metallic base, which is less expensive than brass, and afterwards
imparting to then one or more coatings or coverings of metal, by which they
are rendered equal in appearance and utility to.the same description of article
manufactured.in. brass, whilst a great advantage in point of economy is
obtained.

page_text: We will now proceed to describe the manner in which our Invention is to
be carried into effect. In manufacturing cornice poles and picture rods, we
first produce by any ordinary and suitable means a tube of sheet zinc of the
requisite size, and having the seams or joints brazed or otherwise secured if
it be desirable to have a close tube, or left merely butt-jointed (by which it is
to be understood that the edges are only brought into close contact), when an
open tube will answer the purpose. This tube then receives a coating of brass,
by deposition of that metal in a state of solution, after which, if it be desired
to produce a higher degree of colour and finish, it may undergo the process of
electro-gilding. In manufacturing curtain rings, we also first produce a zinc
tube, and having brazed or soldered the joint (if necessary), we proceed to
turn it round into a ring, in the same manner as now practised in the manu-
facture of brass rings. We then subject the ring to the brassing process,
before described, after which it may receive the subsequent operation of
electro-gilding. The eye for the curtain hook is then rivetted through the
ring, which is then complete. In the manufacture of picture chains, we employ
sheet zinc, from which we stamp or strike up the links of any form of loop
we may require, and then coat them with brass, and electro-gild them
(if necessary) in manner described with reference to the articles before
mentioned.
Having thus described the nature of our said Invention, and the manner
in which the same is to be carried into effect, we wish it to be clearly under-
stood that we do not confine ourselves to these precise details; but that which
we claim as of our Invention is, the improvements described in the manufac-
ture of cornice poles, picture rods, and rings and chains, to be used therewith
by making them of zinc, coated and coloured to resemble brass, as herein
more fully set out and specified.
In witness whereof, we, the said William Pitt and Edward Turner Davies,
have hereunto set our hands and seals, this Eighteenth day of
August, in the year of our Lord One thousand eight hundred and
fifty-five.
