PROVISIONAL SPECIFICATION.
Improvements in Household Chiming Clocks and in Mechanism
connected therewith, the same being partly applicable to Public
and other Chiming Clocks.
We, WILLIAM HENRY WILKINSON of Pelican Works Great Hampton Street,
Electro-plate Manufacturer, trading as T. Wilkinson and Sons, and JOHN KING
WALTER of Brighton Terrace, Park Road, Clockmaker, both of Birmingham
in the County of Warwick do hereby declare the nature of this invention to be as
follows:-
The combination of resonating gongs (Plant and Perry's Patent No 5320, 1884)
with household clocks by means of a particular kind of mechanism of levers and
trackers, for the purpose of chiming the hours and quarters, playing airs, changes,
or musical compositions upon the said gongs.
In mechanism usually employed in household clocks with bells or sounding
instruments other than resonating gongs, the hammer is worked direct from the
barrel, the hammer-shaft itself being lifted by the projecting pins of the revolving
cylinder, but it has been found impracticable to strike the resonating gongs
satisfactorily in this manner.
Our invention consists in disposing the gongs and their corresponding hammers
at any convenient distance from the clockwork and barrel, and connecting them with
the latter by means of levers and trackers, lines of silk or other suitable material,
and in various other ways.
The gongs may be placed in any convenient position inside or outside the clock-
case, or in an adjoining apartment, communication being effected by means of levers
of wood, iron, or other suitable material, or by lines of silk or other cord connecting
the gong-hammers with the clock movement.
We may strike the hour upon one gong, or upon two or more gongs together
forming a concord or a discord, thus giving loudness and novelty to the hour-tone
according to the purpose of application.
This improvement of striking two or more gongs together to form one compound
sound for the purpose of imparting loudness and novelty to the hour-tone of
household clocks made in accordance with our invention, is also applicable to all
other kinds of striking clocks, including turret and public clocks having bells or
other sounding instruments.

5 Improvements in Household Chiming Clocks and in Mechanism
connected therewith, the same being partly applicable to Public
and other Chiming Clocks.
We, WILLIAM HENRY WILKINSON of Pelican Works Great Hampton Street
Electro-plate Manufacturer and trading as T. Wilkinson and Sons, and JOHN KING
WALTER of Brighton Terrace, Park Road Clockmaker, both of Birmingham in the
County of Warwick 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 :-
Our invention relates to improvemente. in household chiming clocks and in

page_text: mechanism connected therewith and consists in the combination of patent resonating
gongs (Plant and Perry's Patent No. 5320, 1884) with the movement of a
household clock by means of a particular kind of mechanism consisting of levers
and trackers, lines of silk or other cord for the purpose of chiming the hours and
quarters, playing airs, changes, or musical compositions upon the said gongs.
In mechanism usually employed in household chiqing clocks having bells or
sounding instruments other than resonating gongs, the hammer is worked direct
from the movement, the hammershaft itself being lifted by the pins of the revolving
barrel. This method however has been found impracticable with resonating
gongs.
Our invention consists in placing the gongs and their corresponding hammers at
a distance from the clock movement either inside or outside of the clock case, or in
another apartment, and working them by means of levers of wood or other
suitable material, or by lines of silk or other cord connecting the gong hammers
with the clock movement.
Each clock may have one or more gongs, according to the purpose of
application.
In a chiming clock made in accordance with our invention we may strike the
hour upon one gong, or upon two or more gongs together, thus forming a concord
or a discord according to the purpose of application. To effect this we arrange the
pins of the barrel to operate simultaneously on two or more gongs, or by an
arrangement of two or more hammers fixed on one arbor and playing upon two or
more gongs at the same time, and in various other ways.
This improvement of striking two or more gongs together to produce a compound
sound for the purpose of giving loudness and novelty to the hour-tone of household
clocks made in accordance with our invention, is also applicable to all other kinds of
striking clocks, including turret and public clocks having bells or other sounding
instruments, and may be effected in such clocks by an arrangement of two or more
hammers fixed on one arbor the same being lifted direct off the pin-wheel and
allowed to strike two or more bells or other sounding instruments simultaneously,
and in various other ways.
In the accompanying drawings
Fig. 1 is a front view in elevation, illustrative of our invention for improve-
ments in household chiming clocks and shewing the manner of striking the gong
above the movement.
Fig. 2 is the same with the gong below the movement, the barrel G revolving in
an opposite direction, but we do not confine ourselves to the precise details
herein described since they may be considerably modified without departing from
the principle of the invention.
A is the gong in its framework B. C the hammer with its bearing at D. E is
a pad or cushion forming a rest for the hammer C. F is a spring fastened to B
and to the hammershaft C to increase the force of the blow. G is the clockwork
barrel with any required number of pins L. L. H is the barrel lever with its
bearing at I and working preferably between the plates of the movement.
J, represents a line of silk or other cord connecting the barrel-lever H and the
hammer-shaft C at their ends K. Instead of a line or cord J may be a lever of
wood or other material hinged loosely to H and C at the points K. This line or
lever J may be of any required length corresponding to the distance of the gongs
from the clock movement.
M is the vibrator or gong note, and N N are supports for securing the gong
frame to the top of the movement or to the bottom of the clock-case.
When the barrel G revolves (Fig. 1) as indicated by the arrow, its projecting
pins L L lift and release alternately that end of the barrel lever H with which
they engage, and motion is thereby communicated, by means of the line or lever J,
to the hammer C, which rises and falls accordingly, striking and sounding the gong
note M in its descent.

page_text: In Fig. 2 the barrel is caused to revolve in an opposite direction as shewn, the
lever H being depressed and released alternately.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is
―.
1. In a household chiming clock, the combination of one or more resonating
gongs with the clock movement by means of lines or levers for the purpose
substantially as described.
2. The line or lever J which connects the barrel-lever H with the hammer-
shaft C, for the purpose substantially as described.
3. Striking the hour simultaneously upon two or more resonating gongs for the
purpose substantially as described.
4. In a household or public clock having bells or other sounding instruments other
than resonating gongs, striking the hour upon two or more bells or other sounding
instruments simultaneously for the purpose substantially as described.
