PROVISIONAL SPECIFICATION.
A Process for Producing Coloured Effects in Metal Work.
I, THOMAS GIBSON Jeweller 144 Camden Street Birmingham do hereby declare the
nature of this invention to be as follows:-
A new method for introducing colours into drugget pins, carpet pins, all kinds of
fancy nails, picture hooks, coffin nails and the like by means of perforation by which
colours can be shown through, as for instance the covering shell of a drugget pin or
nail will be pierced with a pattern and then coloured material placed inside and all
stamped together and thus the colour will be shown through the pattern pierced and
so with picture hooks and the like.

COMPLETE SPECIFICATION.
A Process for Producing Coloured Effects in Metal Work.
I, THOMAS GIBSON, of 144 Camden Street, Birmingham, Warwickshire, Jeweller
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention consists in the herein described improved process for producing
coloured effects in metal articles such as drugget and carpet pins, fancy nails, picture
hooks, coffin nails and the like which process enables the said ornamented articles
to be produced very cheaply and in such a manner that the colours will be less liable
to wear away
I will describe my invention by referring to the accompanying drawings on which
Figure 1 represents in elevation and Figure 2 in plan a drugget pin or fancy nail
constructed according to this invention ;
Figure 3 is a sectional elevation of the same;
Figure 4 is a sectional elevation of the same before going through the final stamping
process; and Fig. 5 shews the parts of the said pin or nail separately;
Fig. 6 represents in front elevation, Fig. 7 in back elevation and Fig. 8 in side
elevation a picture hook constructed according to this invention and Figs. 9 and 10
shew parts of the said picture hook separately.
Referring firstly to Figs. 1 to 5 both inclusive in which the same letters of
reference indicate the same parts.
A is the head of the drugget pin or fancy nail and B is its shank. The head A
consists of an inner disc a as usual fixed to the shank B and covering this disc
is an outer raised sheet brass or other metal shell c perforated in any desired
pattern as by holes d. Immediately beneath the shell c is a disc e of coloured
material, preferably crystal tin, or other suitable substance which will show through
the perforations. The underside of the head is covered by the sheet metal disc fas
usual through which the shank B passes. A disc of cardboard 9 or other suitable
substance is or may be used in the head so as to give solidity. In making the nail
the disc f is threaded on to the shank B and the discs g and e placed upon the
head a and covered by the shell c the edges of which are closed around the discs.
The compound head thus formed (see Fig. 4) is then subjected to great pressure
in dies of corresponding shape, as in a drop stamp, so as to render the head solid
and force the coloured metal or other substance e into the perforations & flush
with the top of the head of the nail, as shewn in Fig. 3, and thus impart an
ornamental appearance to the same.

page_text: In this example, as only one coloured disc e is used, the colour shewing through
each of the perforations & will be the same, but it will be evident that the colours
can be varied by using two or more discs of different colours and sizes so that the discs
underneath will overlap the smaller discs above, or the upper disc or discs may be
notched or have cut away parts so as to shew the disc or discs of a different colour or
colours underneath; for instance, as in the picture hook illustrated by Figs. 6 to 10 in
which two discs of different colours marked respectively e¹ e² are used, the disc el
being for instance red and the disc e blue. The disc or piece e¹ is placed in front of
the disc e² and the former has cut away parts at i so as to show the disc e² behind and
make the perforations d in the part c appear red and blue alternately.
In this example the discs e¹ e² are held in place by tongues c¹ on the front part c
which are closed down on to the disc e².
It will be evident that my invention as above described can be similarly applied to
the ornamenting of those drugget and carpet pins, fancy nails, picture books, coffin
nails and like articles which have heads of a polygonal or other form.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
-
1. The herein described improved process for producing coloured effects in the
heads of drugget pins, carpet pins, fancy nails, coffin nails and the like, consisting in
forming the beads of the said articles of a perforated shell enclosing one or more
coloured metal discs or parts arranged so as to shew through the said perforations, the
said shell and internal coloured parts being compressed together, for the purpose and
substantially as herein before set forth.
2. The herein described improved process for producing coloured effects in the
heads or fronts of picture hooks, consisting in perforating the heads or fronts of
the said articles and securing at the back thereof one or more metal discs or
parts arranged so as to shew through the said perforations, for the purpose and
substantially as hereinbefore set forth and illustrated by Figures 6 to 10 of the
accompanying drawings.
