PROVISIONAL SPECIFICATION.
Improvements in Watch Bars for Watches.
L, MATTHEW WILCOX of 48, Spon End, Coventry in the County of Warwick,
Watch Jeweller, do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object improvements in watch bars for watches and is
for the purpose of producing greater exactness and better fit in the bringing together
of the parts and thus the solidity and stability of the works of the watch is
increased.
This I effect in the following manner :-The steady pins of watch bars have
hitherto been rivetted, tapped, or otherwise fastened into the said bar as a separate
piece of metal but instead of this I use a piece of metal of sufficient thickness to
be able to cut the said pins out of the solid bar by machining enough of the solid
part away to leave the pins projecting above the said surface. These pins may be
of any shape but I make them, by preference, round, as usual, and it will be seen
that it is utterly impossible for the pins to be ilisplaced by turning or by any move-
ment or jerk of the watch, either when at work or when the parts are taken to
pieces for repair.
Thus greater exactness and stability are ensured.
Dated this Seventh day of January 1889.

COMPLETE SPECIFICATION.
Improvements in Watch Bars for Watches.
1 MATTHEW WILCOX of 48 Spon End Coventry in the County of Warwick,
Watch Jeweller do hereby declare the nature of my said invention to be as
follows:-
:-
My invention has for its object improvements in watch bars for watches and is for
the purpose of producing greater exactness and better fit in the bringing together of
the parts and thus the solidity and stability of the works of the watch is increased.
This I effect in the following manner:
The steady pins of watch bars have hitherto been rivetted tapped or otherwise
fastened into the said bar as a separate piece of metal but instead of this I use a
piece of metal of sufficient thickness to be able to cut the said pins out of the solid
bar by machining enough of the solid part away to leave the pins projecting above
the said surface. These pins may be of any shape but I make them by preference
round as usual and it will be seen that it is utterly impossible for the pins to be
displaced by turning or by any movement or jerk of the watch either when at work
or when the parts are taken to pieces for repairs. Thus greater exactness and
stability are ensured.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a sheet of drawings upon which I have
illustrated two applications thereof and from which it will be easy for any workman
to extend the same to any other loose or moveable parts of watches of whatsoever
construction they may be.
Figure 1 is a plan of the back plate of a watch showing the two bars A and B
attached according to my invention.

page_text: Figure 2 is a section through the watch showing the details of the attachment of A
and B to the plate C.
Figure 3 shows the back view of bar A with the solid pins a², a², a projecting
therefrom as having been machined from the plate itself.
Figure 4 is the back view of bar B showing the two solid pins & and
therefrom as having been cut out of the solid plate.
projecting
On reference to Figure 2 it will be seen that the pins a' and a² are quite solid with
the plate A and that they enter into corresponding holes in plate so that there is
absolutely no possibility of the pins moving or turning as in the case of the old plan
in which the pins are rivetted or tapped into the bars.
It will be evident that though I have only shewn bars A and B as having the
solid pins than any other removeable parts may be so formed with their pins from
the solid.
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
The improvement in watch bars for watches having the pins for fixing the same
cut out of the solid with the said bar substantially as and for the purpose herein set
forth and shewn upon the drawings.
