Year: 1884

page_text: I IACOT BURMANN Bienna Switzerland Watch Manufacturer do hereby declare
the nature of said invention for NEW AND IMPROVED ELECTRIC ALARM WATCH OR
CLOCK STAND AND CERTAIN IMPROVEMENTS IN OR CONNECTED WITH WATCHES OR
CLOCKS FOR ACTUATING THE SAID ALARM OR AN ORDINARY ELECTRIC BELL to be
as follows:
This invention consists of a stand provided with an electric alarm arrangement
for watches or clocks which latter are provided with an arrangement so as to
cause the alarm to sound at any desired time or the watch or clock may be put in
connection with the push of an ordinary electric bell so as to actuate it at a
distance.
The drawings accompanying this specification will serve to illustrate the
principle of my said invention.
Fig. 1 shows a vertical section of the watch stand with a side view of the clutches
which hold the watch.
Fig. 2 is a front view of the same. In both views the same letters refer to the
same subjects.
The watch-stand is formed of Box A made of wood or other suitable material in
the under part of which is placed a suitable battery B In the upper part of Box A
is fixed a metallic bearing E upon which is fixed the Bell C by means of a hollow
screw J.
The bell C covers the alarm-mechanism composed of an electro-magnet D with
an armature G carrying a hammer M which strikes against the Bell C as soon as
the magnet is excited.
The head of screw J carries the clutches Z and Z¹ intended to support the watch
The hole in J is provided with a tube L made of an insulating material so as to
insulate the hollow screw J from the screw K which passes through the same. The
screw K is screwed into a metallic bearing H independent of the bearing E and
connected with one pole of the battery B.

page_text: The other pole of the battery is connected with the spring O forming with N an
interrupter which may be acted upon by a button P maintained by spring Q either
in the position shown in the drawing or with the oprings O and N in contact with
one another.
The head of screw K is connected with a spring Y which is formed so as to lean
against the bezel A¹ of the watch when the latter is placed on the clutches Z
and Z¹.
The alarm-watch intended to actuate the electric bell of the watch-stand is an
ordinary watch the case of which is provided with an insulating ring I insulating
the the metallic bezel A¹ from the watch case D' and E¹. The bezel A¹ is provided
with an alarm hand Cwhich may be turned by hand so as to place it opposite any
hour on the dial when it is desired that the alarm shall act. It will be seen by the
above described arrangement of the metallic parts of the watch stand that when the
contact of the interrupter NO has been established by acting upon the button P
the electric current furnished by the battery B will traverse the electro-magnet D
and cause the electric bell to ring as soon as metallic connection is made between
the spring Y and clutches Z or Z¹ which connection is made as follows:-
In Fig. 4 it will be seen that the hour hand B¹ of the watch is provided with a
little spring B which forms a metallic connection between the watch movement
(or case) and the bezel A' as soon as it comes in contact with the alarm-hand CI
thus completing the circuit and causing the bell to ring.
As is shown in Fig. 1 the watch-stand is moreover provided with a button U fixed
on a spring T by pressing which the spring T. is brought in contact with a spring R
fixed on
a screw S of the bearing H so that the alarm may be made to act
independently of the watch if desired.

page_text: I IACOT BURMANN of Bienna Switzerland Watch Manufacturer 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 consists of a stand provided with an electric alarm arrangement
for watches or clocks which latter are provided with an arrangement so as to cause
an alarm to sound at any desired time or the watch or clock may be put in
connection with the push of an ordinary electric bell so as to actuate it at a
distance.
In the accompanying drawing figure 1 shews a vertical section of the watch stand
with a side view of the watch and of the clutches holding the same. Figure 2 is a
front view of the watch constructed according to this invention. Figure 3 is an
enlarged vertical section of the alarm watch connected to the electrical stand
clutches.
In all the figures the same letters refer to the same parts.
The watch stand is formed of a box S made of wood or other suitable material
in the interior of which is placed an electric battery A of any suitable system. The
two poles a and b of the said battery are in electrical contact the one with the
metallic tube X the other with a spring F
The tube X is united to another spring G by means of a wire g and the spring G
leans against the push-pieces K¹ so as to ascertain the electrical contact between the
metallic tube X and the metallic stud Y bearing the contact lever Y¹.
;
The spring F is connected with the solenoid of an electro magnet B which is
fixed to the metallic plate W. A support D is fixed upon the electro-magnet B and
carries the pivots of an armature F of non-conducting material said armature F is
provided with a metallic disc f, with a contact spring H a bell hammer I and a
weight G. The spring H leans upon the contact screw M the stud O of which is
insulated from plate W by means of the pieces P and P¹ made of insulating
material. By means of a screw nut N the length of the contact screw M may be
regulated at will. The bell C is fixed by means of a screw K upon a stud E which
is screwed in the plate W. The metallic head L carries three clutches Z' and Zu
upon which is placed the watch.
From the above described disposition of the metallic parts of the watch stand it
is evident that the electric current furnished by the battery A will traverse the
electro-magnet B and cause the electric bell to ring as soon as a metallic connection.
is made between the stud Y and on of the clutches Z' or Z".
Now the case of the alarm watch intended to cause the ringing of the electric
bell of the watch stand, being provided with an insulating ring I insulating the
metallic glass bezzel A' from the watch case D' and E' and the glass bezzel A¹

page_text: having a metallic hand C¹ arranged so as to come in contact with the hour hand as
soon as the latter passes the hour on which the hand C¹ has been placed by turning
the glass bezzel A it is evident that the aforesaid electrical connection between the
stud Y and the clutches Z¹ or Z¹¹ will be established as soon as the contact lever Y¹
between the hand C¹ and the hour hand is established, if the contact hand Y is in 5
the position shewn in figure 3. The electric current coming from one pole of the
battery passes then from the stud Y into the glass bezzel A¹ and hand C, and from
thence through the hour hand into the metallic parts of the watch mechanism
which is connected with the case D' E' and from there through the clutches Z¹
and Z and through the electro-magnet back to the battery B.
The end of the hand C, or of the hour hand, or of both is, or are provided with
a small spring B₁ arranged so as to determine the time during which the hands
remain in contact with one another.
The push-piece K¹ enables the spring G to be put in contact with a metallic
pin H which is electrically connected with the pole a of the battery A so as to 1
cause the electric bell to ring independently of the above described alarm
arrangement in order to call up an employer or a servant or for other purposes.
Although I have described the watch as applied to my improved stand it is
evident I may employ it so connected with any electric bell as to cause such bell to
ring at any desired time automatically.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
Firstly. The construction of a watch or clock stand provided with electrical.
alarm mechanism substantially as set forth.
Secondly. The means whereby an electric bell is put in action automatically
either in connection with my electric alarm stand or an ordinary electric bell at any
desired time substantially as set forth.
Thirdly. The means whereby a watch or clock constructed as described can be
made to ring an electric bell at any time substantially as set forth.
Fourthly. The combination of a watch or clock. and electric alarm stand
arranged and operated substantially as set forth.
