PROVISIONAL SPECIFICATION.
Improvements in Chiming Apparatus.
I, EDWARD HASTINGS HORNE, of 11 New Inn Hall Street, Oxford, Clerk
in Holy Orders, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in chiming apparatus for small or
large bells whereby I obtain a compact and efficient arrangement of parts capable
of automatically producing a considerable number of "changes."
For this purpose I employ a ringing "barrel," which is made up of a number of
rods parallel to the spindle and arranged round it, each rod being capable of
independent revolving motion on its own axis and carrying one or more projecting
arms or pins to actuate the levers or cranks connected with and operating the bell
hammers.
On each or some of such revolving rods are fixed a ratchet wheel, preferably of
four teeth, to prevent backward motion, and a spur wheel, preferably of eight
teeth, to cause forward motion, placed at or near the ends of the rods. A stop
pawl acts in connection with each ratchet wheel.
In connection with such rods and wheels I employ certain fixed projections or
pins placed near the ends of the "barrel "and not far from the spindle, which
projections or pins are capable of being thrown out of gear. These projections
are intended to gear with and actuate the spur wheels as the "barrel" is revolved,
and thus cause a partial, preferably a quarter, revolution of the rods.
I also place some of the spur wheels (preferably the alternate ones) at one end
of the "barrel," the others at the other end of the "barrel," in order to allow the
projections or pins which actuate some of the spur wheels to be thrown out of gear
for one or more revolutions of the barrel, while others remain in gear thus
increasing the number of changes.
This throwing out of gear of the fixed projections or pins is effected by a step
by step motion operated from the barrel or barrel spindle."
I preferably arrange the projecting arms or pins for operating a given hammer
lever on alternate rods by which means important advantages are gained.
If desired the levers or cranks operated by the projecting arms or pins on the
rods may be shifted in a direction parallel to the barrel spindle to bring them into
position to be operated by a different set of such arms or pins.

Improvements in Chiming Apparatus.
I EDWARD HASTINGS HORNE, formerly of 11 New Inn Hall Street, Oxford,
O but now of 20 Christchurch Road, Hampstead, in the County of Middlesex, Clerk
in Holy Orders, 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 improvements in chiming apparatus for small or
large bells whereby I obtain a compact and efficient arrangement of parts capable
of automatically producing a considerable number of "changes."
For this purpose I employ a ringing "barrel" which is made up of a number of

page_text: rols parallel to the spindle and arranged round it, each rod being capable of
independent revolving motion on its own axis and carrying one or more projecting
arms or pins to actuate the levers or cranks connected with and operating the bell
hammers.
On each or some of such revolving rods are fixed a ratchet wheel, preferably of
four teeth, to prevent backward motion and a spur wheel, preferably of eight teeth,
to cause forward motion, placed at or near the ends of the rods.. A stop pawl.acts
in connection with each ratchet wheel.
I find it convenient, but not necessary, to make the ratchet wheel and the
projecting arms or pins in one piece.
In connection with such rods and wheels I employ certain fixed projections or
pins placed near the ends of the "barrel" and not far from the spindle, which
projections or pins are capable of being thrown out of gear.
These projections or pins are intended to gear with and actuate the spur wheels
as the "barrel" is revolved and thus cause a partial, preferably a quarter,
revolution of the rods.
66
I also, according to one arrangement, place some of the spur wheels (preferably
the alternate ones) at one end of the "barrel," the others at the other end of the
barrel," in order to allow the projections or pins which actuate some of the spur
wheels to be thrown out of gear for one or more revolutions of the "barrel,"
while others remain in gear, thus increasing the number of "changes."
25.
I may also effect the same object of throwing some of the spur wheels out of
gear when all the spur wheels are placed at one end of the "barrel," some being
made to project further from the end of the "barrel" than others, as will be
hereinafter described.
This throwing out of gear of the fixed projections or pins is effected by a step
by step motion operated from the "barrel " or "barrel" spindle. I find it
convenient to use for this purpose a ratchet wheel, preferably of twenty teeth,
which is advanced one tooth at each revolution of the spindle, and which carries
a ring cam acting as hereinafter described.
I preferably arrange the projecting arms or pins for operating a given hammer
lever on alternate rods, by which means important advantages are obtained, but
may arrange them in any other convenient order.
I
And in order that the 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.
The drawings represent one form of machine embodying the invention herein
described.
As the invention consists essentially of the "barrel" and 'its attachments;
including the fixed projections or pins and step by step cam gear, and effects no
novelty relating to the frame, cranks or levers, I may make the machine of any
suitable form and may use levers or cranks of any suitable kind.

In all the figures like parts are indicated by similar letters of reference..

page_text: One of the wires or cords which are connected with the bell hammers (of
which there are eight), is shown at a passing through the top of a wooden case X
enclosing the machine. This wire a is connected to one arm of a crank lever b by
which it is operated; eight of these crank levers are mounted on the horizontal
rod or shaft c carried by the cross bar d. The lower end b¹ of each of such crank
levers is made broader than the upper or main part for wear, and it is kept in its
normal position by resting against the fixed buffere attached to the angle iron f
fixed to the end frames. If desired springs may be used to return the crank
levers to their normal position.
In order to actuate the crank levers b, the revolving part or "barrel" is arranged
as follows: A spindle g supported at its ends in bearings h attached to the end
frames Z, has keyed thereon a plain ratchet wheel; with which acts a stop pawl k
to prevent motion of the spindle g in a wrong direction; the said spindle also
carries a "barrel," made up of two circular iron plates or discs 11 firmly keyed
thereon and having a circle of nine holes in each, see Figure 3, through which
pass nine rods m, each of which has fixed thereon one or more of the following
parts, namely, a ratchet wheel n, a spur wheel p and a stop pawl 9, hereinafter
described.
Each rod m is capable of revolving around its own axis, and the portions thereof
not occupied by the parts n, p, q are covered by short collars or tubes r, which
merely keep such parts in position.
The revolution of this "barrel " or cage actuates the crank levers b, which
operate the bell hammers as above described. There is also fixed on the spindle g,
at its extreme left end, a flat steel arm s, which carries a short steel pin t to
advance the ratchet wheel v one tooth at each revolution of the spindle g.
The fixed pins or projections a pass through a bearing block w and are fixed
into a head piece y, which is moved to the right and to the left with the two pins
by following the motions of the oscillating lever z, a spring y' keeping the head
piece y against the end of the lever z. This oscillating lever z follows the rises
and falls of the ring cam A of the ratchet wheel v.
I will now describe in detail several of the parts above referred to.
The spur wheels p are of the form shown at Figures 1, 3, 10, 11 and 12, having
a boss attached to steady them on their rods m. These spur wheels are made
in three varieties, as shown at Figures 10, 11 and 12, namely, with the boss pl
mainly on the left, mainly on the right or half on each side. If a spur wheel p
used on a rod m has half or more of the boss on the right, that rod will always be
revolved through a quarter turn at each revolution of the main spindle g, for the
fixed projections or pins will never be moved far enough to be out of
gear with
it. On the other hand, if a spur wheel, which has most of the boss p¹ on the left
is used on a rod m, that rod will be unaffected by the fixed pins whenever the
latter are moved to the left by the automatic action of the oscillating lever z and
spring y.
In the arrangement of machine shown there is never more than one of
these wheels p on each bar m.
The ratchet wheels n shown at Figures 1, 3, 4 and 5 have on one side thereof a
semi-circular projection B, which is the projecting arm or pin intended to actuate
the crank levers 6 and ring the bells. There may be as many as four of these
wheels n on one bar, but when two projections can be placed on one wheel the
number will be less than four.
A stop pawl g, which is made with a wide boss see Figures 3, 4 and 5, is placed
opposite each of the four-tooth ratchet wheels n on the next bar to control its move-
ment. The spring which keeps the stop pawl q up to its work, bears against one
of nine small fixed rods D, of which three are shown in Figure 3 and one in
Figures 1, 4 and 5.
The short collars or tubes r are used to fill spaces on the rods m not occupied by
wheels p, n or pawls 9.
A split pin m' is passed through a cross hole at each end of each rod m to keep
the latter in its bearings.

page_text: The manner in which the fixed projections or pins a actuate the spur wheels p is
shown in Figure 3, where four out of the possible nine spur wheels are shown in the
act of passing the two pins or projections & and of being turned a quarter revolution
by them.
The manner in which the semi-circular projections B come into action is shown
at Figure 3, where one of the four-tooth ratchet wheels n is shown having two such
projections. One of these will actuate the crank lever on the first turn of the
shaft g and "barrel," the second on the next turn, and then for two turns there will
be no projection in action on the ratchet wheel n but projections upou one or two
wheels n arranged upon the same bar or rod m, but opposite to other crank levers b,
will then come into action.
By means of the arrangement of machine herein shown and described I obtain
the following results:-
Starting from the position of rest, the rod m which first brings a projection B
into action against one of the crank levers b, rings the bell corresponding to that
crank lever in position 1 among the bells. The rod m which follows next after the
above rod will then bring a projection B into action against another crank lever b,
thereby ringing the corresponding bell in position 2, and so on. As there are four
possible positions of the projections B around each rod m, I can therefore ring as
many as four different bells in position 1 successively in four turns of the handle.
This applies to each of the rods m (but the ninth rod has a somewhat different
character as it relates to the gap or lead between the changes). If then, to give
one example, I make the bells of odd number, 1, 3, 5, 7, to ring only in positions of
odd numbers 1, 3, 5, 7, and even bells in even positions, I have two independent.
sets of changes for four bells each, which changes can be combined in any way I
please without confusion of bells. 1. have only then to cause one of these sets of
changes to fall behind the other set every fourth turn of the handle and I obtain
four times four or sixteen different changes. I find also that by the use of a
20-tooth ratchet wheel with a cam on it, I can still further mingle the changes so
that they do not follow in the same order but change about constantly (though I
have still only 16 different changes) until 80 changes have been rung, when the
order begins again.
By placing two of the projections, which in the arrangement above described
would be on the eighth rod m, on the ninth rod, I obtain a lead or gap not between
each change, but between every other change, as in some methods of ringing by
hand.
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. The use, in connection with a chiming apparatus, of a revolving ringing
"barrel," made up of a number of rods parallel to its spindle and arranged round it,
such rods being mounted in a pair of discs fixed on the spindle and receiving
independent revolving motion and carrying one or more projecting arms or pins to
actuate the crank levers connected with and operating the bell hammers, substan-
tially as herein shown and described.
2. The combination with each of the above mentioned revolving rods, of one or
more ratchet wheels and pawls to prevent backward motion and a spur wheel and
fixed projections or pins acting thereon to cause the forward motion thereof, sub-
stantially as herein shown and described.
3. The combination with the revolving rods and spur wheels above referred to,
of operating pins or projectious capable of being thrown into and out of gear with
the said spur wheels, substantially as herein shown and described and for the
purpose stated.
4. The combination with the revolving rods above referred to, of spur wheels
fixed thereon in different positions and of operating pins or projections so controlled
as to be capable of being taken out of gear with some of the spur wheels for one or

page_text: more revolutions of the ringing "barrel" while other spur wheels remain in gear,
substantially as herein shown and described.
5. In chining apparatus the novel combination and arrangement of parts, sub-
stantially as herein shown and described.
