Date of Application (in United Kingdom), 15th Sept., 1893
Complete Specification Left. 11th May, 1894-Accepted, 23rd June, 1894
An Improved Cap for Watch Movements.
We, AUGUSTE HENCHOZ-ARNOLD, and FRITZ HENCHOZ-HUGUENIN, trading
together as Henchoz frères, of Locle, in Switzerland Manufacturers, do hereby
declare the nature of this invention to be as follows:-
Watch caps as heretofore constructed for covering and enclosing watch move-
ments, to protect them from dust, when to be sent off without their cases, are
difficult to manipulate, both for the watch-maker and for the private individual,
and in order to remove the said cap it is necessary to turn and shake the watch,
so as to cause the cap to fall off. Furthermore, the cap cannot be replaced in
position without touching and injuring the polished surface of the works. The
improved cap about to be described is devised to obviate these inconveniences, and
is capable of ready manipulation.
In the accompanying drawings
Fig. 1 shews a watch movement provided with two studs or projections a¹, b¹, by
means of which the cap shewn in perspective view, Fig. 2, is fixed in place.
This cap consists of a plate A, having a cylindrical rim A', and adapted to
exactly cover the bridges and moving parts of the watch. The studs or pro-
jections a¹, pass through holes a, b, formed in the plate A, and are provided
with notches in which the bolt B engages when it is turned in the direction of the
arrow shewn in Fig. 2. This bolt thus prevents the raising of the cap which it
retains firmly against the movement.
The said cap is also provided with a suitable projection which may be readily
taken hold of when it is desired to remove the cap.
In the arrangement shewn in the drawing the projection consists of a socket C,
serving also to protect the centre square, and provided with a circular groove c
which may be easily engaged between the nails of a person's two fingers. This
projection C may however be of any other suitable form, and may be fixed upon
any other part of the cap.
Dated this 15th day of September 1893.

We, AUGUSTE HENCHOZ-ARNOLD, and FRITZ HENCHOZ-HUGUENIN, trading
together as Henchoz frères, of Locle, in Switzerland, Manufacturers, 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, reference being had to the drawings accompanying our Provisional 5
Specification and to the letters and figures marked thereon, that is to say :-
Watch caps, as heretofore constructed, for covering and enclosing watch move-
ments to protect them from dust, when to be sent off without their cases, are
difficult to manipulate both for the watchmaker and for the private individual,
and in order to remove the said cap it is necessary to turn and shake the watch 1
so as to cause the cap to fall off. Furthermore, the cap cannot be replaced in
position without injuring the polished surface of the works. Our improved cap is
devised to remedy these inconveniences, and is capable of ready manipulation.
In the drawings filed with the Provisional Specification,
Fig. 1 shows a watch movement provided with two studs or projections a', ',
means of which the cap, shown in perspective, in Fig. 2 is fixed in place.
by
This cap consists of a plate A having a cylindrical rim A' and 'adapted to
exactly cover the bridges and moving parts of the watch. The studs or pro-
jections a, b, pass through holes a and b formed in the plate A, and are provided
with notches in which the bolt B engages when it is turned in the direction of the
arrow shown in Fig. 2. This bolt B thus prevents the raising of the cap, which
it retains firmly against the movement.
The said cap is also provided with a suitable projection which may be readily
taken hold of when it is desired to remove the cap.
In the arrangement shown in the drawing, the projection consists of a socket C
serving also to protect the centre square and provided with a circular groove c
which may be easily engaged between the nails of a person's two fingers.
The projection C may, however, be of any other suitable form, and may be fixed
upon any other part of the cap.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The improved cap, provided with a projection (such as C) of any suitable shape,
and fixed on any part of said cap, the projection being so arranged that the cap
may be readily removed from the movement to which it has been applied, substan-
tially as described and for the purpose set forth.
