of the Commissioners of Patents, with his Petition, ou the 26th February
1867.
I, JOHN GEORGE TAYLOR, of 29, Boulevart St. Martin, Paris, in the Empire
of France, Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF CHAINS AND FASTENINGS," to be as
follows:-
My improvements consist, first, in the application to key and other chains
of a spring hook rounded on the inside and outside, thereby remedying the defect
existing in these articles as at présent manufactured, namely, the weakness of
the spring hook. With this spring hook I use any suitable chains, but prefer
chains made of oval wires or rounded both inside and outside.
Secondly, I make what are known as "epinglette" chains with oval wire,"
that is, thick in the middle and thin at the sides; by this means I produce a
chain of equal size to the round wire as at present made, but which chain will
consume much less metal than if made of round wire; these chains may be
made either by hand or machinery.
Thirdly, I make all ordinary chains which are usually made with round wire
with the oval or double-rounded wire already described, my object being to
obtain chains of less weight than when made of the round wire usually
employed.
Fourthly, I make chains as shown in Figures 3 and 4 of the accompanying
Drawing, by means of parts having teeth or undulations fitting into each other;

page_text: I do not bind myself to any size or form of these parts, but it is essential to
my Invention that they fit in to each other, as shown in the Drawing. I use
the springs made with oval wire for all sorts of chains, such as dog chains,
vest chains, bag chains, and for all other suitable purposes..
Fifthly, I make silk, leather, or other chains with fuschia-shaped ornamental
fastenings at the ends, which fuschias may be composed of any metal; by this
system I obtain the form of chain shown at Figure 6; Figure 7 shows
another adaptation of the fuschia instead of the round ball in use. I also
adapt my improved spring hook to all sorts of silk and leather chains.
Sixthly, I make key chains with silk or other textile material, using my
improved spring hook as a fastening.
In the annexed Drawing Figure 1 is a front view of the spring hook for
holding keys together, and also a section of the same through the line 1, 2;
Figure 2 represents a chain made of oval wire, the section being taken through
the line 3, 4; in these two Figures the wire used is oval, as shown; Figures 8
and 4 are two specimens of chains made of pieces of different forms with teeth
or undulations, and united together by soldering, riveting, stamping, or other-
wise; Figure 5 shows the connection of a key chain with the spring hook
represented in Figure 1; Figure 6 shows a silk, leather, or other chain, with
fuschia-shaped ornaments at the ends, which fuschias may be made of any
metal; Figure 7 shows another adaptation of the fuschia instead of the round
ball now used. I adapt my spring hook to all sorts of chains of silk, leather,
or other material; Figure 8 shows a silk or any textile fibre key chain, the
two ends of which may be fastened by any sort of spring hook.
