Improvements in Electric Apparatus for Striking a Bell, Bells, or the
like, or Producing other Effects by Means of and at a Distance
from a Clock.
I, EDWARD ROBERT DALE, of 100 Bedwin Street, Salisbury in the County of Wilts,
Electrical Engineer, do hereby declare the nature of this invention to be as follows:--
This invention relates to simple devices in connection with a clock for performing
an operation at a distance from said clock, such as for instance the striking of one or
more electric bells or gongs, the lighting of a lamp or the operating of any mechanism
for attracting attention signalling or the like. I provide two small metallic washers
insulated from each other by an intermediate washer or layer of vulcanite, shellac, or
the like. One washer is connected by preference by mere tying to the positive wire
from a galvanic battery or other source of electricity, and the other washer is
similarly connected to the negative wire, the circuit passing through an electric bell
at a distance. This washer device is mounted on the clock plate or case or bell
bracket or so that the hammer of the clock in falling or rising strikes against an arm
or piece of wire projecting from one of the metal washers, whereby the circuit is
completed and the electro-magnet of the electric bell is energized so that its clapper
or hammer strikes the bell. Or the clock pendulum may act upon the said projecting
arm instead of the hammer, if it is desired to toll a bell at a distance.

Improvements in Electric Apparatus for Striking a Bell, Bells, or the
like, or Producing other Effects by Means of and at a Distance
from a Clock.
I, EDWARD ROBERT DALE, formerly of 100 Bedwin Street, but now of Crane Villa
Salisbury in the County of Wilts, Electrical Engineer, 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.
My invention relates to simple devices in connection with a clock or the like for
performing an operation at a distance therefrom, such as for instance the striking of
one or more bells, or gongs, the lighting of a lamp or the operating of any mechanism
for attracting attention signalling or the like,

page_text: Fig. 1 shows an arrangement by which the striking hammer of a clock in the act
of striking the hour may also cause a bell at a distance to be sounded.
Fig. 2 shows an arrangement by which the pendulum of a clock when in motion
causes a glow lamp at a distance to be flashed.
Fig. 3 shows an arrangement by which the act of tolling a bell causes a gong at a
distance to be sounded.
Fig. 4 shows an arrangement by which the barrel of a musical clock or the like in
revolving causes the notes to he sounded at a distance by single stroke gongs or other
devices.
Referring to Fig. 1, A is the bell or other device for attracting attention or for
signalling or the like to which is connected one lead a from an electric battery or
other source of electricity B and a lead b direct from an insulated button or washer C
on the clock case D. The lead b is prolonged from the insulated washer C to the
clock plate E with which it is connected.
The other lead c from the battery is carried direct to an insulated button or washer
F on the clock case D and from thence is prolonged and attached to but insulated
from, the clock plate E at any suitable position so that the striking hammer G in
rising or falling in the act of striking the hour may also strike a spring or other
suitable contact piece H connected to the lead c and in so doing complete the circuit
and thereby operate the bell or other device A for attracting attention or for signalling
or the like.
Referring to Fig. 2 A is a glow lamp or other, device for attracting attention or for
signalling or the like to which is connected one lead a from a battery B and a lead b
direct from an insulated button or washer C on the clock case D. The lead b is
prolonged as in Fig. 1 but not shown in Fig. 2, from the insulated washer C to the
clock plate with which it is connected.
The other lead C from the battery is carried direct to one or two insulated buttons
or washers FF conveniently attached to the clock case D so that the pendulum G
when vibrating may strike a spring or springs or other suitable contact pieces H
connected to the lead c and in so doing complete the circuit and thereby cause the
glow lamp A to flash or operate other device for attracting attention or for signalling
or the like.
Referring to Fig. 3, A is'a gong or bell or other device for attracting attention or for
signalling or the like to which is connected one lend a from a battery B and a lead b
connected to the axle or other convenient part of the apparatus usually employed for
tolling for example a church bell.
The other lead c from the primary or secondary battery B is carried direct to an
insulated button or washer F conveniently attached to the framework D so that an
arm or lever G attached to the supporting axle of the bell when vibrating as the bell
is tolled may strike a spring or springs or other suitable contact pieces H connected
to the lead c and in so doing complete the circuit and thereby cause the bell or gong
to be sounded or operate other device for attracting attention or for signalling or the
like.
Referring to Fig. 4, the time barrel Z of a musical clock or box is provided with
holes indentations or the like instead of pins as is more usual and in revolving causes
a series of pivoted weighted levers G which carry at one end insulated contact
pieces G to vibrate. A represents one of a series of single stroke gongs or other
electrical musical devices for producing the melody at a distance to which is connected
one lead a from a battery B and a lead b direct from an insulated button or washer C
on the clock case D. The lead b is prolonged from the insulated washer C to an
insulated washer Ei on the clock plate E and again prolonged from the insulated
washer E' in preferably helical form to the insulated contact piece G¹ at the end of
one of the series of levers G.
The other lead c from the battery is carried direct to an insulated button or
washer F on the clock case D and from there is prolonged and attached to one of a
series of insulated contact pieces H. Normally the contact pieces G are held clear
of the contact pieces H by the plane surface of the cylinder but when the point G³

page_text: of a lever G falls by its own weight into a hole or indentation or the like on the
cylinder Z the contact piece G' strikes the corresponding contact piece H completing
the circuit and thus causing the corresponding gong or other electrical musical device
to be sounded at a distance.
To facilitate the attachment of the leads b and c to the clock case or the like the
two small metallic washers C and F may be joined together but insulated from each
other by an intermediate washer or layer of vulcanite shellac or the like, both
washers being connected by preference by mere tying each to a lead.
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 combination in a clock or the like of electrical contacts in such manner
that the circuit is closed whenever a moving part such as a pendulum hammer or
the like inakes contact with one of the said electrical contacts to perform an operation
at a distance by means of electrical conductors or leads for attracting attention
signalling or the like.
2. The constructions as described and shewn on the drawings.
