PROVISIONAL SPECIFICATION.
Improvements in Bells, and in their Attachment Means.
I, ALFRED NICHOLAS, of Water Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates, in the one part, to cycle and other bells, and in a further
part, to attachment means for securing principally cycle bells to cycles and other
objects.
My invention of the first part consists in clapper or hammer operating mechanism ;
in another part, in a new construction of hammer or clapper, and in a further part,
in means for connecting the said hells to cycles or other objects.
In carrying out the first part of my invention, I take a base plate, bracket or
frame and fit or locate preferably upon the top side of the same, a jointed toothed
sector, having a lever or presser extending itself beyond the boundary of the bell,
and with the teeth of the sector, which is situated upon one side of the base plate,
meshing or intergearing with a half pinion, having made integral or formed in one
piece with it, a toothed sector, which engages with a pinion fast to the hammer
sleeve, mounted upon a vertical axis.
The combined half pinion and toothed sector is mounted and turns upon a hollow
post or pillar, carried by the base plate and encircled by a coiled spring, one end of
which is made fast to the pillar and the other end to the sector and pinion, which
spring is made active by the pressing of the lever, and on the releasing of the lever,
the spring returns the parts of the mechanism to their normal positions.
The movement of the lever sector imparts motion to the half pinion and through
it and its sector to the hammer, which is rotated through its pinion.
The hammer consists of a loose bolt, working stiffly within a case or sleeve and
kept therein and limited in its sliding motion by stops.
The bell, which is mounted over the mechanism, with its inside lower lip or
edge coming approximate to the hammer, sets the hammer bolt, that is, on the said
hammer being rotated, one tip of the bolt, which extends in advance of one end of
its carrying casing, strikes the bell, and is, by the impact, driven in, causing the
other end of the said bolt to extend beyond the other end of the casing and as the
said other end is brought against the bell in its turn, it pushes the bolt hammer
back again, and so on, the bell being continuously struck by the alternate ends of
the bolt.
I wish it to be understood that 1 do not limit myself to the exact means for
rotating the hammer herein described.
In carrying out the means for attaching a bell to a cycle or other object, I fit or
provide the underside of the base plate with a band spring, one end of which is
free and the other fixed or made last to the said base plate. The free end is
pierced with a hole, wherethrough the hooked end of a screwed rod, directed up the
middle sleeve or upright tube of the bell, and taking into a rotating screw box,
having a head extending above the crown of the bell, passes. By rotating the
head, the hook-ended screwed stem is made to advance or retire, and in advancing,
pulls up the band and draws the same around a handle bar or other part of a
machine or other object.
By having the means for slackening and tightening the band clip upon the crown
of the bell, there are no outstanding bolts or other connection parts upon the bell,
and neatness of annearance is obtained

page_text: Instead of the connection being made by the hooked end of the screwed rod
engaging with a hole in the end of the clip, it may be made by rivetting the screw
to the clip or otherwise.
In another form of clip, I provide the band with screwed ends, which, when
brought together, form a divided screwed stem, suitable for taking a screwed head or
nut. When in use, this screwed stem passes through a hole or piercing in the base
plate, which has upon its underside, concaved seatings for taking upon a tube or
other member of a machine or object.
By screwing the screw upon the split or screwed ends of the band clip, the said
band clip is drawn up and the member embraced by it is forcibly drawn upon the
seatings, hence the connection.
The band clips may if necessary be made segmental or in sectional parts, and
connected or joined together by hook and eye ends. Or the said band clips may
be jointed at a part or parts, or the same may be made in two parts jointed claw-
like, and made of stout metal, so as to open out or close upon a tube or other
member, by such means no threading of the clip over or above the member is
necessary, as the attachment is effected laterally.

ALFRED NICHOLAS,
By Henry Skerrett,
Agent for Applicant.
I, ALFRED NICHOLAS, of Water Street, in the City of Birmingham,
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:-
My invention relates, in the one part, to cycle and other bells, and in a further
part, to attachment means for securing principally cycle bells to cycles and other
objects.
"My invention consists in the first part in clapper or hammer-operating
mechanism; in another part, in a new construction of hammer or clapper, and, in a
further part, in means for connecting the said bells to cycles or other objects.
In carrying out the first part of my invention, I take a base plate, bracket or
frame and fit or locate preferably upon the top side of the same, a jointed toothed
sector, having a thumb lever or presser extending beyond the outside boundary of
the bell, and with the teeth of the sector, which is situated upon one side of the
central stem, meshing or intergearing with a half pinion, having made integral or
formed in one piece with it, a toothed sector, which engages with a pinion fast to a
hammer sleeve mounted upon and turning upon a fixed vertical axis and disposed
within the inside of the bell and a central stem.
The combined half pinion and toothed sector is mounted and turns upon a post or
pillar, carried by the base plate and encircled by a coiled spring, one end of which
is made fast to the pillar and the other end to the sector and pinion, which spring
is made active by pressing the lever, and on the releasing of the lever, the spring
returns the parts of the mechanism to their normal positions.
The movement of the lever sector imparts motion to the half pinion and through
it and its sector to the hammer, which is rotated through its pinion.
The hammer consists of a loose plunger-like striker, alike unto a bolt working
stiffly within a case or sleeve and kept therein and limited in its sliding motion
by stops.
The bell, which is mounted over the mechanism, with its inside lower lip or edge
coming approximate to the hammer sets the hammer bolt, that is, on the said

page_text: hammer being rotated, one tip of the bolt, which extends in advance of one end of
its carrying casing, strikes the bell, and is, by the impact, driven in, causing the
other end of the said bolt to extend beyond the other end of the casing and as
the said other end is brought against the bell in its turn, it pushes the bolt hammer
back again, and so on, the bell being continuously struck by the alternate ends of
the bolt.
I wish it to be understood that I do not limit myself to the exact means for
rotating the hammer herein described.
In carrying out the means for attaching a bell to a cycle or other object, 1
fit or provide the underside of the base plate with a band spring, one end of
which is free and the other fixed or made fast to the said base plate. The free
end is pierced with a hole, wherethrough the hooked end of a screwed rod,
directed up the middle sleeve or upright tube of the bell, and taking into a rotating
screw box having a head extending above the crown of the bell, passes. By
rotating the head, the hook-ended screwed stem is made to advance or retire, and
in advancing, pulls up the band and draws the same around a handle bar or other
part of a machine or other object.
By having the means for slackening and tightening the band clip upon the crown
of the bell, there are no outstanding bolts or other connection parts upon the bell,
and neatness of appearance is obtained.
Figure of the accompanying drawing represents partly in vertical section, and
partly in elevation, a cycle bell provided with a repeating striker and striker-
operating mechanism, and also with attachment means, constructed according to my
invention.
Figure 2 represents a complete vertical section of the bell.
Figure 3 represents a horizontal section of the bell upon the dotted lines x-x
Figure 1, thus showing the intergearing driven and driving elements of the
mechanism and the revoluble striker, whose ends are alternately made to strike and
recede inwards on each rotation of the casing within which it is carried and wherein
it slides.
Figure 4 represents a similar view as Figure 2 but with the section taken at
right angles and upon the dotted line A of the said Figure 2.
Figure 5 represents an elevation and topside and underside plans of the striker
casing and its driving pinion.
Figure 6 is a part section and a plan of the bolt-like striker separately.
Figure 7 represents the arbor or upright spindle upon which the carrying casing
of the striker rotates.
The same letters of reference indicate corresponding parts in Figures 1 to 7.
Located within the interior of the bell a, is a reciprocating plunger-like striker b,
carried by and working to and fro within a revoluble carrier casing c, having made
fast to its underside, a pinion d, through which pinion and the centre of the casing
and through a stop-hole 6', in the striker, an arbor or spindle e, carried by the base
plate, upwardly passes and upon which the pinion and casing revolve when the
said pinion is driven by its teeth engaging with those of a toothed sector f, having
upon the opposite side to the toothed part of it, a half piuion f¹, which combined
sector and half pinion rotate freely about the central stem or pillar g, as a centre
of motion.
Encircling the lower part of the central stem or pillar g, is a coiled spring h, with
one end, made fast to the pillar and the other end 2, taking around a stud, on
the toothed sector, so that as the said combined sector and half pinion is partly
rotated through the teeth i', of a toothed lever sector i, turning about the pivot-
pin 3, secured to the said base plate j, as a centre, the coils of the spring are wound
up or compressed, its re-action automatically takes the striker-operating mechanism
back to its normal position.
The toothed sector i, has a thumb lever or arm 2, extending through a gap j2, in
the base plate.
Thus, by pressing the said thumb lever in the direction of the arrow Figure 3,

page_text: the toothed sector i, turns the toothed sector f, through the medium of the half
pinion, whereby the pinion d, is rapidly rotated and with it the revoluble
striker casing c, which, in its turn, carries with it the plunger-like striker b, and
being longer than the casing, one or other of its ends is always projecting to
a distance beyond one or other of the casing ends and within the range of the inside
of the bell, so that as the projecting end is rapidly brought round and against the
inside of the bell it strikes and rings the same and is, by the impact, driven or shot
back through the casing, causing the other end in its turn to extend alike uuto the
first-named end or to be ready to again strike the bell when the said last named end
is brought round to its acting position. This is repeated continuously and two
rings of the bell are made by every single rotation of the striker.
The hollow pillar or stem g, which is carried by the base plate j, and forms the
base to the bell, has fitted within its upper part a rotating screw box k, with
a milled head k³, presented to the crown and with the inside stem part receiving a
like-screwed stalk m, having at its lower end a hook m', over which the pierced and
loose end n of a band clip n, having its after end n², made fast to the base plate j,
passes. The band clip is drawn tightly around the member to which the bell is
attached by turning the milled head k², which draws the screwed stalk m, and with
it the free end of the clip up to the stem g, hence the connection.
Figure 8 represents a section of a modification of the striker part of my
improvements, and Figure 9 a topside plan of the same, but with a portion
removed.
In this form, the striker b, works within an open-topped casing c, instead of
a closed one and is made to move stiffly by a spring p, located round the central
stem e, carried by the base plate j, and between the head e', and a washer <², coming
upon the topside of the striker.
a is the bell, d the pinion, and f the driving sector of it.
Figure 10 represents a further modification of the striker part of my
improvements.
Figure 11 represents the same in vertical section, whilst Figure 12 is a plan
thereof.
In this arrangement the striker, is the same in principle as the one already
described, but the plungers are in duplicate, so that to each rotation of the carrier,
four rings are given instead of two.
a is the bell, b, 62 are the reciprocating strikers, c is the casing or carrier, d the
pinion, e the stem, passing through an axial hole in carrier and pinion and through
slots or stop holes in the strikers, 2 is the stem head having a coiled spring,
coming between it and the washer 2, located upon the topside of the upper
striker b, which has a sinking about its middle for the lower striker to work and be
guided within. f is the sector driving the pinion d, and j is the base plate carrying
the stem e.
When the double striker is rotated, the ends are continuously driven in as they
impinge against the inside of the bell, hence four strikes and rings to each single
rotation.
Instead of the strikers being in duplicate they may be of any convenient number
so as to multiply the rings.
Instead of the connection being made by the hooked end of the screwed rod
engaging with a hole in the end of the clip, it may be made by rivetting the screw
to the clip or otherwise.
or nut.
In another form of clip, I provide the band with screwed ends, which, when
brought together, form a divided screwed stem, suitable for taking a screwed head
When in use, this screwed stemn passes through a hole or piercing in the
base plate, which has upon its underside, concaved seatings for taking upon a tube
or other member of a machine or object.
By screwing the screw upon the split or screwed ends of the band clip, the said
band clip is drawn up and the member embraced by it is forcibly drawn upon the
seatings, hence the connection.

page_text: Figure 13 represents such an attachment arrangement as last described.
a is the bell, g the hollow stem, n the endless band clip, with sectional screwed
stalks n', n, at its ends, which, when placed together, take into and up a screw
box k, which when rotated by its head k³, draws the split stalks up the screwed
interior.
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 :-
-
First. In repeater-action bell mechanism, employing as the striker, a reciprocating
double-striker-ended bolt, working within or upon a revoluble casing or carrier, so
that on being rotated, its ends alternately strike and ring the bell, and by such
impact the said bolt is impelled rearwards and the one end taken from out of range
of the bell and the other end taken into a striking position, substantially as
described and set forth in Figures 1, 2, 3, 4, 5, 6, 8 and 9.
Secondly. In repeater-action bell mechanism, employing a striker consisting of
two or more bolts, each having double striker ends adapted to alternately strike and
ring the bell and be thereby taken into and out of a striking position, as referred to
in the preceding claim and substantially as described and set forth in Figures 10,
11 and 12.
Thirdly. The improvements in the construction of striker mechanism for repeater-
action bells, substantially as herein described and set forth.
Fourthly. In the motion-transmitting mechanism of bells, employing in connection
with the same, a double toothed sector, or a combined sector and half pinion,
revoluble about a post, pillar or upright, and with the larger toothed sector adapted
to engage with the pinion of the striker and the smaller sector adapted to mesh or
engage with the teeth of, and be driven by, a lever sector mounted upon a pin or
pivot as a centre, substantially as described and set forth.
Fifthly. The general construction, arrangement and combination of the
parts of repeater-action bell mechanism, substantially as herein described and
set forth.
Sixthly. An attachment means for bells, consisting of a band clip, with one end
made fast and the other end attachedly connected to a tightening or drawing-up
expedient directed through the bell and operated by a screw box, nut or equivalent
substantially as described and set forth in Figures 1 to 4.
Seventhly. The modified form of bell attachment means described and represented
in Figure 13.
