PROVISIONAL SPECIFICATION.
Improvements in and connected with Alarum Clocks.
WALTER FIELDER of 57 Shakespeare Road, Herne Hill, Surrey Manu-
facturing Electrician do hereby declare the nature of this invention to be as
follows:-
This invention has for its object arranging or employing any alarum clock in
connection with an electrical sounding appliance at any distance therefrom, so
that when an electrical contact is automatically made by the release of the clock
alarum mechanism, the sounding is produced and continues until an intermediate
contact breaker is operated on by hand.
The electric current does not pass through the clock.
In all cases the clock can be used independently either as timepiece or ordinary
alarum, no wires, permanent connections, or other alterations being made.
The invention is principally intended for calling or waking persons.
The alarum clock can be set in one room and the electrical sounder in another or
both can be together.
As an example. The alarum clock is set, say, for six o'clock, and at that hour
the alarum mechanism will cause to establish an electrical contact and set the
signalling appliance in motion wherever that may be placed, which will continue
ringing until the person to be called gets up and stops it by operating on a contact
breaker.
There are several methods by which this invention can be carried into practice.
For instance, the flat or wide part of key which winds the alarum is inserted
between a Ụ, or other shaped projection behind clock and directly the alarum
mechanism is released the key revolves and turns the projection on to a contact
point or plates, thus completing the electrical circuit. The movable piece being
again set by moving clock forward when the said piece automatically returns to its
original position. It can then be used as an ordinary electric call bell by turning
the movable piece either to the right or left as the case may be. The bell rings
ouly when and as long as the movable piece is kept turned.
Another method is for the striker or other part of the alarum mechanism to
release a catch and allow contact to be made by contact maker, thus completing
the electrical circuit. The contact maker can be replaced by hand and the
apparatus used as an ordinary electric call bell.

Improvements in and connected with Alarum Clocks.
IWALTER FIELDER of 57 Shakespeare Road Herne Hill London S.E., Manu-
facturing Electrician, 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 has for its object arranging or employing any alarum clock which

page_text: has the alarum winder or key at the back thereof, in connection with an electrical
sound signalling appliance at any distance therefrom, so that when the electrical
contact is automatically made by the turning of the winder or key when released
by the alarm mechanism the electrical sounding is produced and continues until an
intermediate contact breaker is operated on by hand, or the clock moved forward
or off the stand, thus necessitating the person awakened getting out of bed to stop
the electrical alarum.
I carry out my invention in the manner shown by the accompanying drawing in
which :-
Figure 1 is a view in front elevation illustrating my invention.
Figure 2 is a broken view in end elevation thereof.
Figure 3 is a view in plan thereof, and
Figure 4 is a broken view in back elevation.
D
Throughout the views similar parts are marked with like letters of reference.
Upon a suitable stand X of wood, or other suitable non-conducting material,
I pivot a U-shaped piece of metal A so that the said U-shaped piece is free to
oscillate on its centre. On one side of this U-shaped piece is a terminal screw B
passing through the stand X and provided on the opposite side thereof with the
usual thumb nut b. The terminal screw B is connected with the upper end of the
U-shaped piece A by means of a small spiral spring C which acts both to keep
the said U-shaped piece in a vertical position abutting against the small stop
and also to form an electrical connection between the said U-shaped piece A and
the terminal screw B. Near to the lower end of the U-shaped piece A. is a
second terminal screw B' passing through the stand X and having on the other
side thereof the usual thumb nut. The terminal screws B and B are attached
by wires to an ordinary electric bell and battery in the usual manner. The alarum
clock is placed ou the base X' of the stand X and held firmly thereon by means
of suitable clips or the like so that its alarum winder fits in the U-shaped
• piece A.
When
The action of the apparatus is as follows:-The winder of the alarum having
been wound up the key is left in a vertical position and the clock is placed on the
base of the stand so that the said key engages with the U-shaped piece A.
the time arrives for the alarum to work the winder begins to revolve and
immediately forces the U-shaped piece over into contact with the terminal screw B,
thus completing the circuit and causing the electric bell or other sound signalling
appliance to act until stopped by the person awakened, either by moving the clock
forward or off the stand, or by operating any intermediate contact breaker.
It will be understood that the parts A, B and B', will be arranged with respect
to each other and to the base of the stand to receive and fit an alarum clock of any
desired shape and construction.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction herein before described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The improved apparatus for operating electric bells or other sound signalling
appliances from alarum clocks, substantially as hereinbefore described and illustrated
by the accompanying drawing.
2. The combination of the stand X and base X', of the oscillating piece A, of the
terminals B and B and of the spring C, all combined, arranged and operating, as
and for the purpose set forth.
3. The combination with an alarum clock and an electric bell or other sound

page_text: signalling apparatus, of a contact maker and breaker adapted to be operated by the
winder or key of the alarum mechanism of the clock, as set forth.
