Improvements in Bicycle and like Bells
(A communication from abroad by NELSON FOGG HUMPHREY, of the City of
Boston, in the County of Suffolk, State of Massachusetts, United States of
America, Mechanic.)
I, ALFRED GEORGE BROOKES, of 55 & 56 Chancery Lane, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:.
This invention relates more especially to that class known as single stroke bells,
and the object of the same being to obtain a sharp, decisive blow, and the
immediate retraction of the hammer, from the edge of the bell, so as not to
muffle the tone.
In the drawings, Fig. 1 is a top or plan view with the bell removed but shown
in dotted lines.
Fig. 2 is a section on line 2.2 Fig. 1.
Fig. 3 is a section on line 3.3 as shown in Fig. 4.
Fig. 4 is a section on line 4.4 as shown in Fig. 3.
As shown in Fig. 1. A, is à section of the handle bar of a bicycle, to which
is clamped the bell B, by suitable clamp screws a.
Secured on the clamp strap a¹ is a post or projection a² having a screw threaded
portion a3 to support a bell a*.
On the post or projection is secured an arm a³, the outer end a of which is
turned at right angles with a perforation a' in order that a piece of spring wire a
may be passed through the same, one end of the said spring wire as is partly
bent around the post or projection a² and passed through the perforation a and
in order to give elasticity to the spring wire as a whole turn a is made in the said
spring wire, and at a point a10 on the said spring wire is secured a hammer a,
the said spring wire is then carried over and forms a loop or eye a¹³ for the
purpose of engaging with the lever a¹.
The lever a is pivoted on the post or projection a² one end of which is carried
towards the edge of the bell so as to engage with the projection a6 and act as a
resistance spring to the hammer spring when it strikes the edge of the bell,
thereby preventing the hammer from muffleing the tone of the bell, the opposite
end is passed through the loop or eye a¹³ of the spring wire a and carried under
and outside the edge of the bell in order that a handle may be formed and carried
a sufficient distance so as not to interfere with the tone of the bell.
The outer end of the lever a¹ is made in the shape of a circle as at a¹ and
is covered with an eyelet a" as shown in Figs. 3 and 4 to give the same a finish,
and make it easy to operate.
As the lever a¹ is pivoted on the post or projection that supports the bell, the
handle of the lever will swing in the same arc of a circle as the outer edge of the
bell, thus allowing the handle to be placed nearer to the edge of the bell than is
the general custom.

page_text: In pulling the lever a" in the direction of arrow 10 the spring wire a³ with its
hammer a is drawn over by the loop or eye a¹³ in the same direction, causing a
tension on the hammer spring wire a8 and the opposite end a¹ of the lever a¹ is
moved an equal distance from the projection as and when the lever a¹ is released
the hammer through its spring, tension strikes the edge of the bell, and is instantly
brought away from the same by the end a¹5 coming in contact with the projec-
tion aº.
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:
-
1. In combination with a bicycle or like bell, the hammer, with its spring wire
engaging with an operating lever, said operating lever resisting the hammer from
the edge of the bell, substantially as described, and for the purpose set forth.
2. In combination with a bicycle or like bell, the hammer, with its spring wire.
engaging with an operating lever, said operating lever, resisting the hammer from
the edge of the bell, and movable in the same radius of circle, as the circum.
ference of the bell, substantially as described, and for the purpose set forth.
3. In combination with a bicycle or like bell, the hammer, with its spring wire
engaging with an operating lever, said operating lever, resisting the hammer from
the edge of the bell, and the handle end of the lever covered with an eyelet.al
substantially as described, and for the purpose set forth.
Dated the 7th day of December 1897.
