I JOHN HARRINGTON of the Enamel and Cradle Spring Works, Coventry in the
County of Warwick, Manufacturer do hereby declare the nature of the said
Invention for IMPROVEMENTS IN OR CONNECTED WITH CHIMING APPARATUS to be
as follows:
The invention has for its object a novel arrangement of parts whereby I am
enabled to set chiming apparatus in work by means of a clock connected thereto
by electrical connections and whereby I am enabled to cause a clock to regulate
the action of such chiming apparatus when they are both in close juxta-position or
when they are separated by a considerable distance and even in different rooms.
For this purpose I employ a clock of any ordinary construction and a separate
chiming apparatus provided with its own driving gear, and I cause the minute hand
or some other suitable moving part of the clock to make and break contact at the
required times so as to cause an electric current to pass through the connecting
wire and through an electro magnet or solenoid and thereby give motion to a lever
or to a sliding bar which is provided with a stop.
This stop is so arranged that when in its normal position it will come against
the fly or other moving part of the chiming apparatus to stop any motion thereof,
but when a current is passing through the electro-magnet or solenoid, the said stop.
is moved out, of the way and the chiming apparatus is permitted to work.

I JOHN HARRINGTON of the "Enamel and Cradle Spring Works" Coventry in
the County of Warwick, 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:—
The invention has for its object a novel arrangement of parts whereby I am
enabled to set chiming apparatus in work by means of a clock connected thereto by
electrical connections and whereby I am enabled to cause a clock to regulate the
action of such chiming apparatus when they are both in close juxta-position or
when they are separated by a considerable distance and even in different rooms.
For this purpose I employ a clock of any ordinary construction and a separate
chiming apparatus provided with its own driving gear, and I cause the minute
hand, or some other suitable moving part of the clock to make and break contact
at the required times so as to cause an electric current to pass through the
connecting wires and through an electro magnet or solenoid and thereby give
motion to a lever or to a sliding bar which is provided with a stop. This stop is
so arranged that when in its normal position it will come against the fly or other.
moving part of the chiming apparatus to stop any motion thereof but when a
current is passing through the coil surrounding the electro magnet or solenoid the
said stop is moved out of the way and the chiming apparatus is permitted to work.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation and Figures 2 and 3 are opposite end elevations of
an ordinary chiming apparatus fitted with my improvements: a is the driving
barrel which may be rotated by a weight or by a spring; this driving barrel a by
suitable gearing as shown, or by other suitable arrangements of gearing gives
motion to the pin barrel b, to the fly c and to the locking plate d; ee are the
hammer or striking levers which are acted upon in the one direction by the pins bl
of the pin barrel band in the other by springs f. To the framing of the chiming
apparatus under the outer end of the stop lever I mount an electro magnet h or
it may be a solenoid, which when an electric current is caused to pass through the
surrounding coil attracts the outer end of the detent or stop lever g and thus
liberates the locking plate d and the fly c thereby enabling the chiming apparatus
to work.
The said detent or stop lever g is for the above purpose provided with an
armature g¹ and with a pin g' working through a slot in the plate or frame which
pin when in the position shown in the drawings comes into contact with a pin c¹
projecting from the axis of the fly c. i Figure 2 represents one of my improved
chime sounding tubes, for which I obtained Letters Patent No 14270 of the
year 1884 but gongs or other suitable sounding apparatus may be employed.

page_text: Chiming apparatus constructed in the manner shown in the drawings or in any
other well known manner and provided with an electro magnet h or solenoid to act
on the detent or stop lever ġ may be fixed at any desired distance from the
regulating clock or even in different rooms and a number of such chiming
apparatuses may have their electro magnets or solenoids h connected by electrio
wires to the clock which latter is fitted with one or more insulated contact pieces
connected with one pole of the battery or other source of electricity whilst the clock
is in metallic contact with the other pole of the battery. I cause the minute hand
or some other suitable moving part of the clock to make and break contact with
the aforesaid insulated contact piece at suitable times so as to cause an electric
current to pass through the connecting wires and through the electro magnet or
solenoid h which will then attract the armature g¹ and so liberate the locking
plate & and fly c thereby setting free the chiming apparatus which will continue to
act until the contact is again broken by the action of the clock, and the detent or
stop lever g by being liberated from the electro magnet or solenoid h again falls
into one of the notches of the locking plate d.
I have not thought it necessary to represent in the drawings a clock provided
with one or more insulated contact pieces and capable of making and breaking
contact therewith and of transmitting an electric current to the electro magnet or
solenoid has such aided by the above description will be readily understood.
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
Providing independent chiming apparatus with an electro magnet or solenoid
capable of acting on an armature carried by a stop or detent and electrically
connecting such chiming apparatus with a clock which is capable of making and
breaking contact substantially as herein described and for the purpose stated.
