IMPROVEMENTS IN. CHIMING AND REPEATING CLOCKS
Year: 1884

page_text: I ADOLF OBERLE of 20 Lord St. Cheetham Hill Road, Manchester in the County
of Lancaster de hereby declare the nature of my invention for "IMPROVEMENTS IN.
CHIMING AND REPEATING CLOCKS" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement ;—
The object of my invention is principally to simplify the construction of chiming
and repeating clocks, and consists in the employment of two trains only instead of
three, as is usual, which will make the clock, almost as simple as an ordinary eight
days clock. The trains may be driven either by springs or weights, with fusee or
going barrels. One train is working the going part of the time-piece, and the other
train is working the four-quarters chiming and hour striking part, thus giving the
same result as when three trains are employed and chiming or repeating the first,
second third, and fourth quarter on four or more bells or gongs and then striking
the hour.
And in order that my invention may be better understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference,
corresponding letters indicating like parts in the various figures.
Fig. I on the said drawing represents a represents a front view of a chiming and
repeating clock, constructed according to my invention and showing the chiming
and repeating mechanism at rest. Figures 2 and 3 are side views.
Fig. 4 is a front view of the wheel mechanism of the clock.
Fig. 5 is a front view indicating the position of the different parts when the
repeating commences. Fig. 6 is also a front view, showing the means for actuating
the quarter chiming rack. Referring to Figs. 1. 2. 3. 4. a is the frame of the clock
within which are suitably mounted the trains b & c which may be driven either by
springs or weights with fusee as illustrated in the drawing in Fig. 4. or going
barrels..
The said train b, is working the going parts of the clock by means of the wheels efg,
and the train c working the four quarter chiming and hour striking part by means
of the wheels h. i. k. On the spindle or axis within the frame a is fixed the
barrel m, provided on its periphery with pegs or pins n, which come into contact
with four or more hammers o, the latter chiming the respective quarters, on the
bells por gongs, when the barrel m is rotated. The side of the said barrel m near
to the front plate of the frame a, is also provided with pins g which for a certain
length of time are brought into contact with the lever r, fixed on the shaft s which
D

page_text: carries the hammer for striking the hours. The barrel m is caused to slide in its
bearings by means of a spring t which is fixed at the back plate of the frame a, and
presses against the barrel spindle or axis l. As soon as the hour rack lever r, with
its arm u disengages the incline v¹, formed on the lower part of the lever v the
action of the spring t causes the barrel m, to slide forwards and bring either the
pegs or pins q into contact with the hammers o, thus causing to strike the hour or
chime the quarters respectively. When the chiming, repeating or striking
movement is at rest as shewn in Fig. 1. the barrel m is pushed back and
kept out of operation by the arm u' of the hour rack u which presses on the
incline v formed on the lever v. The locking lever w which engages and
disengages the hour rack and quarter rack x at certain times is provided at one
end thereof with two teeth y instead of only one as usual for the purpose of
overstepping the open space z, which is formed between the second and third
teeth of the hour u and quarter rack z.
The open space z has for its object to leave room for the gathering pallet y¹ to
revolve, whenever the hour and quarter racks. u & are at rest or when the
hour rack is working and the quarter rack x is at rest or vice versa. The teeth
of the locking lever w which gear with the teeth of the quarter rack x are longer
than the teeth of the locking lever w, which gear with the hour rack, in order
that during the time when the locking lever w is engaged, with the teeth of the
quarter rack, the hour rack u is clear of the teeth of the locking lever w. and
will only come into gear with the latter, and commence its functions after the
teeth of the quarter rack x have passed the teeth of the locking lever w.
Both of the said rack levers are arranged to rock on the same fulcrum or pin 1.
The action of the chiming or repeating movement is as follows:-The bell crank
Jever 2 is actuated by the pins 3 fixed on the wheel 4 see Fig. 5, which drives a
part of the finger movement, and causes to lift the locking lever w, at the first,
second, and third quarter always to the same height, and thereby disengaging the
quarter and hour rack levers x & u. During the time the arın ¹ of the quarter
rack lever x falls on to the quarter snail 5; the hour rack lever u is prevented
from falling by means of the pin 6 which is fixed thereto and bears against the
lever 7. When lifting the locking lever w, the pin 8, fixed thereto will clear the
arms of the gathering pallet y', and the chiming and striking movement will begin
to act in order to chime the respective quarters, while the gathering pallet y', will
revolve freely in the open space z of the hour rack lever u. This action is repeated
until it is time to chime the four quarters. When the bell crank lever 2 is caused
to lift the locking-lever w higher than previously, and thus lifting at the same
time the lever 7 and disengages the latter from the pin 6 of the hour rack
lever u.
The tail of the latter as well as the tail of the quarter rack lever will then
fall on their respective snails 5 & 9. see Fig. 6, when at the same time the catch
lever 10 by means of a spring 11, is caused to engage the top part of the lever v
and retaining the latter in a slot formed at the extremity of the catch lever 10,
thus preventing the barrel m, from sliding. After such has taken place it will
chime the fourth, during which time the locking lever wis not in gear. with the
hour rack lever and will permit the tail u² of the latter to fall back on its snail 9
by each stroke.
During the last stroke the pin 12 which is fixed on the quarter rack x comes
into contact with the catch lever 10, and disengages the latter from the lever v
which causes the barrel m to slide and bring the pins q for striking the hours into
contact with the lever . At the same time and as the fourth quarter has been
chimed the locking lever wis engaging the hour rack lever and will pass the
latter striking the respective hour, during which time, the gathering pallet y', will
revolve disengaged in the open space z of the quarter rack lever x.
During the last hour stroke the arm u¹, presses the hour lever u against the
incline of the lever vand presses the barrel m back again to its original
position. viz. near the arm of the quarter chiming hammer o. The locking

page_text: ering pallet y is prevented from rotating by the pin 8 of the locking lever w.
aving now particularly described and ascertained the nature of my said
ntion, and in what manner the same is to be performed, I declare that what I
n is
CLAIDIS.
In a four quarter chiming and repeating clock, the employment of two
trains b & c only, instead of three as is usual, one train b working the going
part of the time piece and the other train c working the four quarter
chiming and hour striking part, for the purposes specified. substantially as
described and illustrated in the annexed drawings.
d. The combination of the hours rack, lever u, and quarters rack lever x,
gathering pallet y'. locking lever w, lever 7. bell crank lever 2 lever v
catch-lever 10, barrel m and snails 9 & 5. for the purpose specified
substantially as described and illustrated in the annexed drawings.
