Improvements in Alarm Watch Bracelets.
I, CARL OTTO MAJOR of Marschallstr., Dresden, in the German Empire, Hotel
Keeper, 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 relates to a bracelet or wrist or arm band provided with a watch
in combination with a mechanism which when suitably adjusted has for object to
wake, rouse or remind the wearer at a given time by means of a blow or other
sensation of feeling.
In the accompanying drawing
Figs. 1, 2, 3, are respectively side views and a top view of the bracelet.
The other figures shew details of construction.
The watch with its mechanism and the waking or reminding mechanism are
firmly attached to the bracelet. The awaking or reminding mechanism consists of
a pin a, or of a hammer, fixed underneath the watch mechanism to a spring lever b
having a tendency to spring downwards and raised by a tappet disc c through a
lug d fixed on lever 6 for a length of time corresponding to the strength of the
spring, to then, upon every time one of the tappets e of disc c slides away from
lug, pass through an aperture in the inner circumference of the bracelet and
deliver a blow upon the wrist or arm surrounded by the same (Figs. 5, 7, 10). The
spring (watch spring) serving to drive tappet disc c is lodged in a casing e' and
wound up by turning knob f thereby actuating toothed gearing g, h, a spring pawl
engaging in teeth of wheel g. This driving spring is independent of the watch
mechanism which has a special driving spring of its own.
The operation of the spring in casing e is retarded by a train of wheels one of
which is carried on the spring casing and the others 2, 3, 4, 5, 6, 7, 8, in connection
therewith.
In order to propel the pin a or a hammer to strike the wrist or arm at a given
time the unwinding or slackening of the spring lodged in casing e' is altogether
prevented by the arrest by means of a pins of a wing or arm t,-acting as a
socalled fly-carried on spindle of toothed wheel 8 and means are provided for the
release of the fly at the desired time by the action of the watch mechanism. The
means consist in the stop pin & being fixed to a flat spring u arranged underneath
the watch dial v and carrying the hour wheel w which is provided with a lug or
tappet x. When the time for waking or reminding the wearer has not arrived this
lug or tappet is held down by a tubular part y turning and adjustable from the
dial (Figs. 8, 11, 13) by means of a so called waking pointer z. In Fig. 11 the fly
is shewn in the arrested position the hour wheel w and with it spring u and stop
pins being held down from tappet but so soon as the waking time has arrived
this tappet springs into a recess 1 (Figs. 8, 11, 13) in tubular part or spindle y on
which the waking pointer z is fixed thereby also allowing the hour wheel and with
it the stop pin to be sprung upwards by spring u the stop pin being thus removed
from the fly or arm t (Fig. 10). For this purpose the recess I on party is so
adjusted relatively to the axis of the waking pointer that when this is set at the
desired waking or reminding time the tappet x which moves in a circle with the
hour wheel w underneath part y may spring into the recess 1 of this latter at
the time indicated by the waking pointer. In order to be able to set the waking
pointer z without the necessity of removing the watch glass 2 underneath which it
is located there is fixed in the bracelet a ring 3x (Figs. 1, 2, 3) containing the
watch work 4* (Figs. 8, 10) shewn in dotted lines only and the waking or reminding
mechanism. Above the dial va mounting 5* holding the watch glass, arranged to

page_text: turn and provided with a recess 6× (Figs. 8, 11,) receives in this recess the inner
end of the waking pointer (Figs. 11, 14) so that this may be set by turning the
watch glass mounting.
The ring 3x is held in the bracelet which is suitably formed for the purpose by
means of the finger spindles f, f³, one of these serving for winding the watch
mechanism and the other for winding the waking or reminding mechanism. The
watch glass mounting 5* is held in the ring 3x by studs 7x (Figs. 8, 11) fixed
therein and which engage in an annular groove 8* of mounting 5*. In order that
this may not be turned in the same direction as the hour wheel w the bracelet is
provided with a spring pawl 9 (Figs. 1, 2, 3, 12) which engages in teeth formed in
the outer edge of mounting 5* thereby allowing this to turn only in the direction
shewn by the arrow (Fig. 12). As the bracelet, in order that the pin a or hammer
operated from tappet disc c may act efficiently, must closely encircle the wrist or
arm, means are provided for giving the bracelet play when there is no cause for
waking or reminding the wearer. They consist in extending the length of the
spring catch 10 (Figs. 1, 2) of the bracelet closure and providing the same with
projection 11 which when in the closed position (Fig. 2) or partly open position
(Fig. 1) takes against a projection 13 or 13x, in the hollow part 14 of the bracelet
for the purpose in the latter case of opening the bracelet between the parts 14
and 15 (Fig. 1) to a certain extent, and preventing any further undesired opening
of the same.
It is obvious that instead of a pin or a hammer other instruments may be used
and operated for waking, rousing or reminding the wearer of the bracelet for
example a slight cut, scratch, pinch etcetera may be given. Further the bracelet
instead of being formed of two rigid parts may be constructed of links or chain
work or of a rigid upper part of metal attached to the wrist or arm by a chain or
strap.
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. A watch bracelet the watch of which is in connection with mechanism by
which after adjustment of the same and at at time determined beforehand the
wearer is waked, roused, or reminded by the communication of a sense of feeling
from the bracelet substantially as described and shewn.
2. A waking or reminding bracelet which when there is no cause for waking,
rousing, or reminding the wearer may be set in an extended or partly open position
to allow of free play for the wrist or arm, substantially as described and shewn.
