COMPLETE SPECIFICATION.
Improved Alarm Clock with Double Bell.
I, ROBERT FRIEDEL, a subject of the Emperor of Germany, of Villa Villeroy,
Schramberg (Wurttemberg), in the Empire of Germany, Merchant, 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:-
This invention relates to an alarm clock whose characteristic feature consists
in the arrangement of two bells. By this arrangement of two bells, the efficiency
of the alarm clock is considerably increased, since the oscillating haminer, which
is operated in the usual manner by the alarm mechanism, strikes against a bell
in both directions. If bells of different tone are chosen, the alarm sounds
peculiar, somewhat like the railway signal with double-tone bells. The bells
are provided either on one common support or on separate arms.
On the accompanying drawings are shown various modifications of both
arrangements.
Figs. 1 & 2 are front elevation & plan of an alarm clock, according to which
the bells a, a¹ are supported by vertical pins b, b₁ secured to the arms A A' of
the support or bracket, which is provided on a pin C of the clock case or in any
other suitable manner.
In Figs. 3 & 4, which are likewise front elevation & plan of a second modifi-
cation, the suspension of the bells a, a¹ is effected directly on the supporting
arms A A' in such a manner that the bells are located below these arms and
horizontally.
Figs. 5 & 6 are front elevation & plan of a modification, according to which the
bells a, al are provided on the supporting arms A A' laterally and in a vertical
position.
Figs. 7 & 8 are front elevation & plan of two different modifications of the alarm
clock, according to which both bells aa are attached to separate supporting
arms B B and may be suspended from the arms (Fig. 7 left side) or mounted
upon same (Fig. 7 right side).
In all modifications, the construction of the clock and its alarm mechanism
remains as usual, for which reason an explanation thereof has been desisted from.
It may only be observed that the slot c in the casing for the stem of the hammer d
is located, if the bells are arranged symmetrically to the vertical axis of the
clock, in the centre between the same in order that the hammer d may strike with
the same force against both bells. The shape of the clock case, as also its material
is of no moment for the invention; protection is claimed for the arrangement
of a double-bell or of two bells in connection with all forms of alarm clocks.
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. An improved alarm clock with two bells, against which strikes the oscillat-
ing hammer arranged in the centre between the same substantially as described
hown in the drawings

page_text: 2. An improved alarm clock with two bells secured either on one or on separate
supporting arms substantially as described and shown in the drawings.
3. An improved alarm clock with two bells of different tone substantially as
described and shown in the drawings.
