improvements relating to Cycle and like Bells.
1, HARRY LUCAS, of Tom Bowling Lamp Works, Little King Street, in the
City of Birmingham, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention consists of improvements relating to cycle and like bells, my
object being to provide a simple connection between the dome or upper part and
the base or bottom plate, and to so arrange the same as to improve the sound or
tone of the bell.
In the application of my invention to the construction of a bell for attachment
to a cycle or like vehicle, 1 form the dome or upper part of the bell from suitable
metal in the ordinary manner, with a projecting screwed stem from its interior or
under side. The base or bottom plate of the bell has a stem projecting from its
upper side which we screw into or attach with one end of a flexible connecting
piece secured, at its opposite end to the dome or upper part, and thus the two parts
are connected together by a flexible joint permitting of the free vibration of the
dome when struck by the hammer or striker.
With one method of making the flexible joint or connecting piece, I twist a
circular or other wire to the form of a spiral spring, making the pitch of the coils
and the pitch of the threads of the projecting stems to correspond with each other,
thus enabling the stems to be screwed into the coil.
By another method I form the joint by coiling a flat strip of metal, afterwards
cutting the necessary screw thread within the same.
I attach the bell to the cycle or other vehicle by means of a clipping band or
strip, or in any other convenient manner.
I do not limit the application of my invention to bells of any one type or
pattern, but adapt the same to the construction of varying forms of bells,
making such modifications as may be necessary to suit the particular service
required.
I, HARRY LUCAS, of Tom Bowling Lamp Works, Little King 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 :-
This invention consists of improvements relating to cycle and like bells, my
object being to provide a simple connection between the dome or upper part and

page_text: Dase or bottom plate, and to so arrange the same as to improve the sound or
tone of the bell.
In the accompanying sheet of explanatory drawings to be hereinafter referred to;-
Figure 1 is a front elevation, partly in section, representing an alarm or signal
bell constructed in accordance with my invention and mounted upon a supporting
stand or stem.
Figure 2 is an elevation of the base plate of the bell with a clip bracket fixed
to it for the purpose of attachment to the handle bar or in some other suitable
position upon a bicycle or other vehicle..
Figure 3 is an inverted plan of the dome or upper part of the bell showing the
central flexible connection.
Figure 4 is a part sectional elevation of the dome showing the central projecting
stud to which the upper end of the flexible connection is affixed.
Figure 5 is an elevation of the base plate stud to which the lower end of the
flexible connection is affixed.
Figure 6 is an elevation of the flexible connection.
The same reference letters in the different views indicate the same parts.
In the application of my invention I form the dome or upper part A of the bell
from suitable metal in the ordinary manner, preferably providing an internally
projecting lug a (Figure 3) which is struck by the sliding hammers B on their
reciprocation by the lever C and intermediate mechanism not shown on the
drawings, such mechanism forming no part of this invention. The base plate D is
attached to the upper part of the supporting standard or stem E (Figure 1) or to
a clip bracket G, Figure 2, by the end F of the screw stud F which is shown
separate at Figure 5, such screwed part being made of the required length to suit
the stem or clip to which the bell is to be attached.
The dome A and the base plate D are secured together by the flexible
connection J consisting preferably of steel wire of a circular section which I coil
to form a spiral spring such as is shown at Figure 6. Over each end of the
spring I force a retaining collar such as J¹ and in the interior of each end I cut
a screw thread for the reception of the central screw stud A¹ projecting from the
underside of the dome, and the screwed sleeve K. The sleeve K has a tapped
hole formed through it to receive the end F of the screwed stud F. The two
parts are thus connected, as shown at Figure 1, by a flexible joint permitting of
free vibration of the dome when struck by the hammers. The flexible connection
also permits of a slight movement of the dome relatively to the base plate in the
event of the bell falling and striking the ground or a hard substance, and it is thus
rendered less liable to damage than a bell having a rigid connection between the
two parts.
Instead of screwing the studs F and K into the ends of the flexible joint or
connection as herein before described, I sometimes employ plain or unscrewed studs
and press or force them into the opposite ends of the spring or when employing
screwed studs I may make the pitch of the threads to correspond with the pitch of
the coils of the spring forming the joint or connection.
I sometimes form the flexible joint by coiling a flat strip of metal, afterwards
cutting the necessary screw thread within the same or making other provision for
its attachment to the dome and to the base plate.
I do not limit the application of my invention to bells of any one type or
pattern, but adapt the same to the construction of varying forms of bells,
making such modifications as may be necessary to suit the particular service
required.
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. In cycle and other like bells the use of a flexible joint or connection
substantially as and for the nu

page_text: 2. The construction of a flexible joint or connection for a cycle or like bell
consisting of a coil spring J having external collars J and an internal sleeve or
bush K at its lower end, the upper end of the spring being secured upon the dome
stud A substantially as and for the purposes described and as illustrated.
3. The improved cycle or like bell comprising a dome such as A and a base
plate D secured together by a flexible connection such as J, in combination with
suitable hammers and striking mechanism substantially as described and as
illustrated.
