Improvements in or connected with Alarm Clocks.
I, ALBERT SILBERMANN of 74, Blumen Strasse, in the Kingdom of Prussia,
German Empire, Manufacturer do hereby declare the nature of this invention to
be as follows:-
My present invention has reference to improvements in or connected with alarm
clocks, consisting in an arrangement attached to an ordinary alarm clock, by which
means a light is struck, at the same time as the alarm is set in motion.
I attach to the back of the spring-drum of the clock a segmental-shaped cam
which sets in motion the apparatus for lighting a candle, and which acts only when
the spring-drum of the alarm begins to revolve.
In order to make my invention more fully intelligible, I will proceed to describe
the form of apparatus I prefer to use, with reference to the accompanying drawing,
in which:
Fig. 1 is an elevation of the clock-work mechanism.
Fig. 2 is a side view partly in section of the clock-work mechanism with the
apparatus for igniting a candle attached to the back thereof.
Fig. 3 is a rear elevation of the apparatus, after the candle has been ignited.
Fig. 4 is a rear elevation of the same, but showing the apparatus, before the
alarm has been set in motion.
Figs. 5 to 10 are various details.
To the back of the clock A a casing B is attached containing the igniting
apparatus. This apparatus is set in motion by a segmental-shaped cam a attached
to the alarm-drum C coming in contact with a pin 6 which is connected to the
apparatus in B.
In the tube e is placed a candle-holder f, which presses upwards under the
influence of the spring g. f is provided with a handle h moving vertically in the
slit i of the tube e, by which the candle can be pressed down ready for lighting.
The top of the casing B is provided along part of its length with a slit m,
widening out to a circle at a spot vertically above the opening of the tube e.

slide n; in this latter is also provided a small hole r in which catches the rod s, on
the slide being moved towards it, as shown in Fig. 4. This rod s has towards its
lower end a thread cut in it and carries here a nut t, from which projects towards
the clock-work mechanism the pin b. The end of the rod moves vertically in the

COMPLETE SPECIFICATION.
Improvements in or connected with Alarm Clocks.
I, ALBERT SILBERMANN, of 74 Blumen Strasse, in the Kingdom of Prussia,
German Empire, 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 :-
My present invention has reference to improvements in alarm-clocks, consisting
in an arrangement attached to an ordinary alarm-clock, by which means a light is
struck, at the same time as the alarm is set in motion.
I attach to the back of the spring-drum of the clock a segmental-shaped cam
which sets in motion the apparatus, for lighting a candle, and which acts only when
the spring-drum of the alarm begins to revolve.
In order to make my invention more fully intelligible, I will proceed to describe
the form of apparatus I prefer to use with reference to the drawing filed with my
Provisional Application, in which :
Fig. 1 is an elevation of the clock-work mechanism.
Fig. 2 is a side view partly in section of the clock-work mechanism with the
apparatus for igniting a candle attached to the back thereof.
Fig. 3 is a rear elevation of the apparatus, after the candle has been ignited.
Fig. 4 is a rear elevation of the same, but showing the apparatus, before the
alarm has been set in motion.
Figs. 5 to 10 are various details.
To the back of the clock A a casing B is attached containing the igniting
apparatus. This apparatus is set in motion by a segmental-shaped cam a attached
to the alarm-drum C coming in contact with a pin which is connected to the
apparatus in B.
In the tube e is placed a candle-holder f, which presses upwards under the
influence of the spring g. f is provided with a handle h moving vertically in the
slit i of the tube e, by which the candle can be pressed down ready for lighting.
The top of the casing B is provided along part of its length with a slit m,
widening out to a circle at a spot vertically above the opening of the tube e. A
slide n with an igniting surface o moves to and fro in the slit m.
A small pin p
behind which presses the end of a spring q (Figs. 3 and 4) projects down from the
slide n in this latter is also provided a small hole in which catches the rod s, on
the slide being moved towards it, as shown in Fig. 4. This rod s has towards its
lower end a thread cut in it and carries here a nut t, from which projects towards
the clock-work mechanism the pin h. The end of the rod moves vertically in the
small tube w, and is forced upwards under the influence of the spring u.
The action of the whole apparatus is as follows:
с
A candle with a self-igniting wick is placed in the holder f, which is then by
means of the handle h pressed down into the tube e compressing the spring g. The
slide is then moved over the opening of the tube e, and is held by the rod s
catching in the hole r. On the alarm-drum e being set in motion by the clock-work,
the curved cam a strikes against the pin b pressing it down, thus withdrawing the
rods from the hole r, and releasing the slide n, which under the influence of the
spring 9 flies back, the rubbing surface o igniting the wick of the candle, which
thereupon is pushed up by the spring y in tube e.
The slide is arrested at the side of the casing by the stop p, which is provided

page_text: with the handle y for the purpose of removing it from its seat, should it be
required to renew the igniting surface o.
I extend the winding pins c and d of the alarm and clock out through the
casing B, so that this casing need not be removed, when it is necessary to wind up
the clock.
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. In an alarm clock, the combination with the alarm drum c, of a cam a,
operating a rods by means of a pin b, whereby the rod s is withdrawn from its
normal position and releases a slide n, which, under the influence of the spring
flies back, and causes the rubbing surface to ignite the wick of the candle k,
substantially as herein before described and illustrated by the drawings.
2. The general construction, arrangement and combination of the several and
respective parts, together forming my invention of improvements in alarm-clocks,
substantially as herein before described and illustrated by the drawings.
