1, RICHARD CHARLES MARSH, of 76, High Street, Birmingham, in the County of
Warwick, Watch Manufacturer, do hereby declare the nature of my said 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 has for its object improvements in watches and has particular
reference to the mode in which the bows are attached to keyless watches. Hitherto
very great weakness has existed in the attachment of the bow to the pendant as the
bow cannot penetrate all the way through the pendant because of the winding spindle
and hence the bows continuously separate from the pendant and are an endless cause
of trouble. They also offer very great facilities to pick-pockets as a single twist of
the hand will remove the bow therefrom-at any rate in ordinary watches this is the
case.
Now my invention is intended to obviate this difficulty.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a sheet of drawings upon which I have
shown four figures illustrating the parts constituting my invention.
They are as follows:-
Figure 1 is a broken off front elevation of the face A of a watch showing the
bow B partly in elevation and partly in section as well as the button S, and spindle s¹
and the pendant E.
Figure 2 shews the pendant part E as it would be made according to my
invention.
Figure 3 is the locking ferrule K which when added to Figure 2 forms a part of
the pendant.
Figure 4 is a general view of the bow B.
The button S shown in Figure 1 with its spindle s¹ which is broken off passes
through the pendant E in the usual manner and would be attached to the usual
winding gear inside the watch, and in this button and spindle there is no novelty.
The pendant E is new in construction and consists of two pieces viz. the bottom
piece E and the upper outside portion or ferrule K. The inner part of K is tapped
with a screw thread to fit upon the reduced upper part of the pendant E. In each
side of the pendant E I cut a hole e which finishes with the narrow neck e³.

page_text: The bow B shown clearly at Figure 4 has the two ends reduced to the necks 1
but leaving the enlarged shoulder at each end. This bow is shown in position at
Figure 1 and is put together by inserting the shoulder through the hole in the
neck of the pendant, when the bow is slided down into the smaller part e² when the
screw cap or ferrule K is screwed upon the upper end of the pendant until it reaches
the neck of the bow which it permanently secures in position.
The effect of this arrangement is that the enlargements at each end of the bow B
has the same effect as a rivet head and prevents the bow from being either twisted off
or withdrawn excepting very great force indeed or some mechanical instrument is
applied for the purpose of shearing it. It will thus be seen by this simple arrangement
that I am able to secure the ends of the bow in self-winding watches almost as securely
as is the case if the bow were one solid ring.
It will be obvious that instead of the enlargement e² in the neck pendant E the
slot may continue up to the top of the neck so that the bow would slide down from
the top the ferrule then following so as to lock it in position. The ferrule K may if it
is found necessary be secured against turning back by the insertion of a pin either
vertically or crosswise or it may be made in two parts like lock nuts.
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 improvements in watches consisting of a bow having the reduced necks b¹ and
collars at the end thereof fastened inside the pendant tube E and locked therein
substantially as and for the purpose herein set forth and shown upon the drawings.
