Improvements in Bell Action Mechanism.
I, JAMES GLAZEBROOK STORMONT of Maney, Sutton Coldfield, in the County
of Stafford, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in bell actions, or bell action ringing
mechanism, and consists essentially in the employment of angular shaped spring
arms, terminated by clapper heads at their free ends, and clamped or fixed at their
other ends, and with the said arms, arranged in the form of the letter T, with a steel
spring lifter (in the form of a flat sheet steel or other spring metal tongue) inter-
posed between them; so that on the said lifter being pressed aside, by the passing
and repassing of the wiper end of the short arm of a lever, the branches of a
forked end, or the teeth of an escape lever or toothed quadrant, the clapper spring
arms are alternately lifted, and suddenly released, hence the ringing by the contact
of the clapper heads with the lip of the bell.
In carrying out one form of my invention in connection with a cycle bell, with a
double pair of clappers, I secure the inner ends of the angular branches of the
clapper arms, to the middle of a central pillar or axis, upon the terminal ends of
which, the bells come, and with the lips of them, coming within a short distance of
each other, sufficient for the working of a lever between them, without touching.
The free ends of the spring arms, which are directed outwardly, and at right
angles to the attached ends, are terminated by clapper heads, arranged to come
approximate to the lips of both bells, while between the said attached ends of the
clapper arms, which are made from spring thin sheet metal, thin sheet metal spring
tongues are interposed, which are alternately acted upon by dissimilarly disposed
wiper ends of the branches constituting the short arm of an operating lever,
jointed and fulcrumed to an outstanding bracket, lying between the clapper arms,
and with a T-piece constituting a stop, terminating it.
ACTION.
Assuming that the wiper end of the first branch of the lever, is upon the top
side of the interposed lifter, the turning of the lever upon its joint centre, deflects
the said lifter downwards, turns back the lower clapper arm of the front side, and
after the said wiper end has passed the lifter, the same springs back, and so also
does the clapper arm and clapper, hence a ring. The further movement of the
lever, brings the other branch of the short arm of it, upon its interposed lifter,
which depresses or pushes back, and releases, the other clapper arm, hence a second
ring, while the return or back movement of the lever, pushes the lifters aside, and
so again operates the upper pair of clapper arms, and so gives an intermittent
ring.
The action may be repeated or multiplied by increasing the number of branches
or teeth.
Instead of the acting ends of the short arm of the lever being branched and
terminating in dissimilar planes, the said end may be made in the form of a toothed
quadrant or sector, with the teeth presented and overhanging the free ends of the
interposed lifters, so that the describing of an arc by the lever, lifts and releases
alternately the lifters, hence a repeater action, with continuous ringing.
The lever is returned to its normal position, by a distension, coiled or other
spring. Or the said lever may be made to reciprocate a rack, whose teeth over-
hang and come in contact with the spring tongue lifter, or lifters, as aforesaid, so
D

page_text: that by the reciprocation or raising and falling of the rack, the teeth are made to
impinge consecutively upon the yielding and free end or ends of the lifter or lifters,
which are turned aside, and suddenly released, on the passage of each and every
tooth, hence continuous ringing.
My bell action mechanism is applicable for single, double, multiple, or other
repeater action ringing bells.
The levers, or their equivalents, may be in the form of hand wheels, provided
with teeth or otherwise.

Improvements in Bell Action Mechanism.
1 JAMES GLAZEBROOK STORMONT of Maney, Sutton Coldfield, in the County
of Stafford, Mechanical 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 :-
This invention relates to improvements in bell actions, or bell action ringing
mechanism as hereinafter described.
Figure 1 of the accompanying drawing, represents partly in section, and partly
in elevation a cycle bell, provided with repeater action ringing mechanism, con-
structed and arranged according to my said invention.
Figure 2 represents a cross section on the dotted lines A B Figure 1, and
showing the upper clapper heads of the clapper arms respectively, and also how
the toothed sector at the inner and jointed end of the thumb lever, engages with
the tip of the free end of a deflector spring, which, by its alternate change of
position, through the medium of the teeth as aforesaid, operate respectively and
intermittently the clappers whose arms are made of spring metal.
Figure 3 represents partly in section, and partly in elevation, the said bell, but
viewed at right angles to the position as represented in Figure 1.
Figure 4 represents a plan of the striking mechanism separately.
Figure 5 represents an edge view of the same, with the clappers separated, and
with the deflecting spring coming between them.
Figure 6 is a plan of the said deflecting spring, whilst
Figure 7 represents a combined toothed sector, and thumb lever or pull.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a, b, are double armed clappers, having angular branches a, b, made from spring
metal, terminated outwardly by heads a³, 3, and with the inner ends a, b, clamped
and firmly held by an affixing screw c, taking into a supporting bracket d',
branching from a pillar d, upon the ends of which the crown and foot bells e,/, are
secured.
is a deflector, in the form of an interposed flat steel spring, located between
the inner and parallel branches of the said clapper arms, and with the tip g², which
is free to deflect, extending itself beyond the head end branches of the said clapper
arms, and with which free and extended. end, the teeth of toothed sector 43, of a
thumb lever, jointed at 13, supported by ramified bracket arms, engage so that on
the lever being moved in the direction of the arrow, the deflector is deflected in
the direction of the dotted arrow, and by it, the angular Branches a² are deflected
intermittently outwards, whilst the return movement of the said lever through the
intervention of the coiled spring which is distended by the first movement,
deflects the said tip end g², in a reverse direction, thereby intermittently deflecting
...*2.

page_text: the branches, hence a repeating action by the intermittent striking of the spring
clappers against the lips of the respective bells, both on the forward and back
motion of the lever.
Thus assuming the mechanism of the bell to be in a condition as represented in
Figure 2, the pulling of the lever in the direction indicated by the arrow, causes
the first tooth of the toothed quadrant, to press forward the free end of the
deflector, and then suddenly, release the said tip, which comes upon the second
tooth; then by the still continued movement of the lever, the second tooth bends
the deflector to the extent of a further tooth, and releases it, and so on to the
number of the teeth of the sector, and as the clapper arm is suddenly released by
the said tip end of the deflector wiping over the teeth, an impact, or a striking is
performed at each sudden release. Then by the repassing of the said teeth past
the tip end as aforesaid, on the lever returning to its normal position through the
intervention of the pull spring i, an intermittent ringing is performed by the
clapper heads of the branch deflected by the reaction.
The lever is prevented from being pulled too far, by stops 4, coming against
the supporting bracket which carries the said lever (as a stop).
The bell is carried by a band or other clip j.
Instead of employing a toothed sector for giving a succession of rings, by the
passing and repassing of the teeth of the same over the free end of the deflector,
a single tooth or wiper end may be employed to press forwards or backwards the
deflector or the deflector escape, and further, instead of jointing the thumb lever
forward of the tip of the deflector spring, the same may be extended in length, and
jointed on the opposite side of the clamping screw to that shown in the drawing,
and with the tooth or teeth of the same presented to the tip of the free end of the
deflector in front.
Instead of employing two bells or ringing domes, three or more may be employed,
in which case, three or more double or single sets of clappers are employed and
operated in manner as described.
In the clapper arm mechanism, instead of arranging branches upon the two
opposite sides of the yielding deflector escape, branches or clappers may be
arranged on one side only, hence the ringing only in one way instead of both ways.
as before described.
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
:-
First In bell action repeating mechanism, actuating the clippers by means of
a spring deflector or a yielding deflector escape, disposed or located between the
clapper arms, carrying one, two or more clapper heads, for the striking of one
two or more bells, substantially as described and set forth.
Secondly In bell action repeating mechanism, arranging spring clappers or
the inner branches of them upon the two opposite sides or upon one side of a spring
deflector, or a yielding deflector escape, operated by a lever or like expedient, as
described and set forth.
:
Thirdly I bell action repeating mechanism consisting essentially of clappers,
having interposed between them a spring deflector escape, operated by a toothed
thumb lever, brought back by a spring, and which said parts are constructed,
arranged, and operate and cooperate in manner and for the purpose, substantially
as described and set forth.
