PROVISIONAL SPECIFICATION.
Improvements in and relating to Bells for Velocipedes.
We, JOSEPH LUCAS, and HARRY LUCAS, trading as J. Lucas and Son, of the
Tom Bowling Lamp Works, Little King Street, Birmingham, in the County of
Warwick, Manufacturers, do hereby declare the nature of this invention to be
as follows:-
Our invention relates to certain improvements in the construction of bells for
velocipedes whereby we obtain a more perfect and reliable instrument ;-
We construct our improved bell in the following manner;-On a suitable bracket
adapted to be fixed to the handle bar, or other convenient part, of the velocipede
are mounted two gongs. In the hollow space formed by and between them is
mounted on a suitable pivot a U-shaped arm carrying a clapper at each end, one
clapper being set to strike one gong and the other the other gong. Connected with,
or forming part of this U-shaped arm is a straight arm having a longitudinal slot
with which engages a pin mounted eccentrically on a disc mounted on a short axle
carried in a suitable bearing on the main bracket. This bearing is preferably
formed by a snug on the bracket and an undercut to receive a small spur pinion on
the end of the axle carrying the disc with eccentric pin.
In a suitable position on the main bracket is fulcrated a finger lever having a
toothed quadrant, or its equivalent, engaging with the pinion on the axle carrying
the disc with the eccentric pin, thus adapting the finger lever to manipulate the
U-shaped arm carrying the clappers and so sound the bell; the proportion between
the pinion and the toothed quadrant being such as to cause the clappers to
reciprocate several times to once of the finger lever. A suitable spring is arranged
to operate between the finger lever and the main bracket to restore the finger lever
to its normal position. To prevent the parts rattling or shaking I employ the
method of locking the lever and reciprocating arm as set forth in Challis Patent
No. 16451 of 1886, of which we are the registered proprietors. We so arrange the
several moving parts that as they approach their normal state of rest by the action
of the spring, the end of the finger lever carrying the toothed quadrant is moving
in an opposite direction to the slotted lever attached to the arm carrying the
clappers, and on each of these parts we form a projection the one adapted to come
in contact with the other, so that they are kept firmly up to one another by the
action of the spring controlling the finger lever, and thus prevent the several parts
rattling or shaking due to the vibration of the machine.
It will be obvious that the striking mechanism hereinbefore described may be
applied to bells having only one gong equally as well as to those having two.

Improvements in and relating to Bells for Velocipedes.
We, JOSEPH LUCAS and HARRY LUCAS, trading as J. Lucas & Son, of the
Tom Bowling Lamp Works, Little King Street, Birmingham, in the County of

Price 811

page_text: what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
Our invention relates to certain improvements in the construction of bells for
velocipedes, whereby we obtain a more perfect and reliable instrument.
Our improved bell is constructed in the manner shown in the accompanying
drawing in which
Figure 1 is a view in plan of a bell having a double gong, and
Figure 2 is a view in side elevation-partly in section-thereof.
Throughout these views similar parts are marked with like letters of reference.
On a suitable bracket A adapted to be fixed to the handle bar or other con-
venient part of the velocipede are mounted two gongs B and B in the usual
manner.
In the hollow space formed by and between these two gongs is mounted on a
suitable pivot a U-shaped arm C carrying a clapper at each end, one clapper e
being set to strike the gong B, and the other clapper c' to strike the gong B¹, as
shown in the accompanying drawing. Connected with, or forming part of, this
U-shaped arm C is a straight arm D having a longitudinal slot d with which
engages a pin e fixed eccentrically to a disc E mounted on a short axle e' carried
in a suitable bearing a on the bracket A. This bearing a is undercut to receive
a small spur pinion F on the axle e carrying the disc E with the eccentric
pin e.
In a suitable position on the bracket A is fulcrated a finger lever G having a
toothed quadrant G', or its equivalent, engaging with the pinion E on the axle e',
thus adapting the finger lever to manipulate the U-shaped arm C carrying the
clappers c and c¹ and so sound the bell, the proportion between the pinion and the
toothed quadrant being such as to cause the clappers to reciprocate several times
to once of the finger lever. A spring H is arranged to operate between the finger
lever G and the bracket A to restore the finger lever to its normal position after
movement. To prevent the parts rattling or shaking we
employ the method of
locking the lever and reciprocating arm as set forth in Challis' Patent No. 16451
of 1886 of which we are the registered proprietors. According to this device the
several moving parts are so arranged that as they approach their normal state of
rest (by the action of the spring) the end of the finger lever carrying the operating
mechanism is moving in an opposite direction to the arm carrying the clapper or
clappers, and on each of these parts a projection is formed the one adapted to come
in contact with the other, so that they are kept firmly up to one another by the
action of the spring controlling the finger lever, and thus prevent the several parts
rattling or shaking due to the vibration of the machine.
In applying this device to our improved bell, we form or fix on the arm C a
downward projection d¹ and on the toothed quadrant G¹ carried by the finger
lever G we form or fix a snug g in such a position that it will
come into
contact with the projection d' on the arm C before the quadrant G has come
to the end of its return stroke, and be kept engaged therewith by the action of
the spring H.
It will be obvious that this mechanism can be applied to bells having but one
gong equally as well as to those having two.
We wish it to be particularly understood that we do not bind ourselves to the
exact details of construction hereinbefore set forth and shown by the accompanying
drawing, but that we hold ourselves at liberty to make such changes and alterations
as fairly fall within the spirit and scope of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1st. The improved bell, constructed, arranged, and operating, substantially as
herein set forth and illustrated by the accompanying drawing.

page_text: 2nd. In a velocipede bell, the combination with one or more gongs or bells, of
a finger lever carrying a toothed quadrant, of a reciprocating arm carrying one or
more clappers and having connected with it a slotted arm the slot of which is
adapted to receive a pin mounted eccentrically on a disc operated by the toothed
quadrant on the finger lever through a small spur pinion, of a projection on the
aforesaid slotted arm adapted to engage with a snug on the toothed quadrant, and
of a spring acting between the finger lever and the bracket of the bell, all combined,
arranged, and operating, as and for the purpose set forth.
Dated this 10th day of April 1891.
