Williams at the Office of the Commissioners of Patents, with their
Petition, on the 17th March 1868.
We, WILLIAM HULSE and EDWIN WILLIAMS, both of Birmingham, in
the County of Warwick, Manufacturers, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE MANUFACTURE AND ORNAMEN-
TATION OF METALLIC BEDSTEADS AND OTHER ARTICLES OF METALLIC FURNITURE,
▲ PART OF WHICH IMPROVEMENTS MAY ALSO BE APPLIED TO THE ORNAMENTATION
OF METALLIC TUBES AND OTHER METALLIC ARTICLES," to be as follows:-
Our Invention consists, firstly, of the following improvements in
manufacturing the head and foot rails of metallic bedsteads and like
parts of other articles of metallic furniture. The said head and foot
rails generally contain an ornamental panel. In making the ornaments
of the said panels we take a plate of sheet iron of a size and shape
proper to form the foundation of the said panel, and we make several
holes in those parts to which the ornaments are to be applied. We
place the said plate in a mould which has been prepared in the ordinary
way for the production of the required ornament by the casting process.
The said plate is situated in the mould, between the two halves of which

page_text: the mould is composed the ornament in one half, the mould being on
one side of the plate, and that in the other half of the mould on the
other side of the plate. Melted cast iron being poured into the mould
ornaments are cast on each side of the mould, the ornaments on one
side being connected with those on the other side through the holes
in the plate, the melted metal running through the said holes and
forming junctions between the ornaments on the two sides of the plate.
The panel may be finished by painting or japanning or in any other
manner.
Our Invention consists, secondly, of the following method of orna-
menting the pillars of metallic bedsteads and other articles of metallic
furniture:We first lacquer the brass or other pillar, or lay on a ground
of the required colour; we harden this lacquer or ground by stoving
so as to render it secure against being removed by the subsequent treat-
ment; we next apply a lacquer of the colour which the ornament is
required to have; this lacquer is applied uniformly over the whole of
the tubular surface. We next draw or paint on the surface in asphaltum
or Brunswick black the design which it is wished to produce on the
pillar in the colour last applied; or the design may be applied by the
process of transferring. After the design has hardened we immerse the
pillar in a solution of common soda or other alkaline solution, by which
treatment the whole of the second or coloured coating of lacquer is
removed, excepting that covered by the design in asphaltum or Bruns-
wick black. After removing the pillar from the soda solution and
washing and drying it, we apply turpentine or other liquid which will
dissolve asphaltum or Brunswick black, by which treatment the design
in the coloured lacquer underneath is exposed. The pillar so treated
has an ornament in the colour of the second coating of coloured lacquer
on a ground of the first coating of lacquer or other ground.
This part of our Invention is applicable to the ornamenting of
cylindrical and taper and other kinds of pillars for metallic bedsteads
and other articles of metallic furniture as well as to metallic tubes for
various purposes, and to metallic articles in general.
