PROVISIONAL SPECIFICATION.
Improvements relating to Cycle and like Bells.
We, HARRY LUCAS, Managing Director, and AUGUSTINE CAMPBELL DAVISON,
Engineer, both of the Firm of Joseph Lucas Limited, of "Tom Bowling" Lamp
Works, Little King Street, in the City of Birmingham, do hereby declare the
nature of this invention to be as follows:-
This invention consists of improvements relating to bells for cycles, motor-
cars, and other services, of the type in which the ringing or sounding of the bell
is effected automatically by the rotation of one of the wheels of the vehicle.
The object of our invention is to arrange for the attachment of the bell with a
portion of the vehicle framing adjacent to a wheel in a neat and convenient man-
ner, and to provide simple and effective means whereby the bell mechanism can
be readily put into connection with the wheel or disconnected therefrom as
required.
in the application of our invention to a bell to be arranged for operation by
the front or steering wheel of a cycle, we connect the ordinary dome of the bell
by its central pin or stud to a metallic arm or bracket suitably formed to permit
of its attachment with one of the sides or legs of the steering fork by means of a
band clip, or fastener, such as is now employed for the attachment of a bell to
the cycle handle.
On an extremity of the central pin or stud of the dome which projects beyond
the bracket we pivot an arm or lever, the outer or free end of such lever being
connected by a catgut line or otherwise with an operating lever or finger piece
conveniently arranged on the cycle handle. On the lever pivotted upon the dome
stud we mount a spindle which projects through a slot in the bracket herein-
before referred to, and carries at one end a toothed wheel for engaging a like
wheel formed with the hammers, and mounted with them on the dome pin or
stud; the opposite end of the spindle carries a roller to be rotated by contact
with the rim or tyre of the front or steering wheel of the cycle.
The roller is normally kept out of contact with the cycle wheel by the action
of a spring arranged in combination with the lever on which the roller is carried,
but when the rider moves the operating lever or finger piece, herein before referred
to, against the action of the said spring the roller is forced into contact with
Whilst the roller is inain-
the cycle wheel and will thus be rotated thereby.
tained in contact with the wheel the bell will ring continuously with the rotation
of the wheel, but on the release of the operating lever or finger piece the afore-
said spring will withdraw the roller from the wheel and thus stop the ringing
of the bell.

E CAMPBELL DAVISON,
Tom Bowling" Lamp
Engineer, both of the Firm of Joseph Lucas Limited, of
Works, Little King Street, in the City of Birmingham, 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 consists of improvements relating to bells for cycles, motor-
cars, and other services, of the type in which the ringing or sounding of the bell
is effected automatically by the rotation of one of the wheels of the vehicle.
The object of our invention is to arrange for the attachment of the bell with a
portion of the vehicle framing adjacent to a wheel in a neat and convenient man-
ner, and to provide simple and effective means whereby the bell mechanism can
be readily put into connection with the wheel or disconnected therefrom as
required.
Un the accompanying sheet of explanatory drawings to be hereinafter referred
to.-
Figure 1 is a side elevation representing a portion of the front end of a bicycle
having a bell with automatic ringing mechanism arranged thereon in accordance
with our invention.
Figure 2 is a plan showing the bell with its attachment bracket and operating
roller or disc.
Figure 3 is an elevation of the bell from the base plate end, showing the
pivoted arm or lever on which the operating disc is mounted, and a portion of the
attachment bracket.
Figure 4 is an end elevation of one of the guide brackets for the bell line.
Figure 5 is a plan view showing the bell line pull lever.
The same reference letters in the different views indicate the same parts.
In the application of our invention to a bell to be arranged for operation by
the front or steering wheel of a cycle, we fix the bell A to a metallic arm or
bracket B suitably formed to permit of its attachment with one of the sides or
legs as C of the steering fork by means of a band clip fastener D such as is now
employed for the attachment of a bell to the cycle handle.
On the extremity E of the central pin or stud of the bell which projects beyond
the bracket B we pivot an arm or lever F, the outer or free end of such lever
being connected, preferably by a catgut line G, with an operating lever or finger
piece H pivoted upon the bracket J which is clipped in a convenient position on
the cycle handle bar. On the lever F we mount a spindle K. which projects
through a slot in the bracket B and in the base or cover plate A' of the bell,
and carries on its end within the bell a toothed wheel for engaging a like wheel
formed with the hammers, and mounted with them on the central pin or stud
of the bell in the ordinary manner. The outer end of the spindle K carries the
roller L which is rotated when pressed into contact with the rim of the front or
steering wheel of the cycle. The roller L has a rubber band embracing its rim
or periphery, and if desired the parts herein before described may be so arranged
as to permit of the rotation of the roller being effected by contact with the tyre
instead of with the rim of the wheel.
The roller L is normally kept out of contact with the cycle wheel by the action
of a spring M arranged in combination with the lever I on which the roller is
carried, but when the rider moves the operating lever or finger piece H, herein-
before referred to, against the action of the said spring, the roller is forced into

page_text: contact with the cycle wheel and will thus be rotated thereby. Whilst the roller
is maintained in contact with the wheel the bell will ring continuously with the
rotation of the wheel, but on the release of the operating lever or finger piece
the aforesaid spring will withdraw the roller from the wheel and thus stop the
ringing of the bell.
The bracket N carrying the roller n is clipped on the handle bar in a suitable
position for effectively guiding the bell line G.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In cycle and like bells in which the ringing or sounding is effected auto-
matically, the combination with a fixed arm or bracket having the bell mounted
thereon and provided with means for its attachment in a position adjacent to
one of the road wheels of the cycle or other vehicle, of a pivoted arm or lever
carrying the mechanism whereby the motion of the said road wheel is trans-
mitted when necessary to the bell mechanism, substantially as described and as
illustrated.
2. The general arrangement and combination of parts forming the means
whereby the mechanism of a bell for a cycle, motor-car, or for like services, can
be readily put into connection with a wheel of the vehicle or disconnected there-
from as required without movement of the bell itself, substantially as and for
the purpose described and as illustrated.
