1, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by Heinrich Wissner, of Mehlis Thuringia, in the Empire of Germany,
Manufacturer,) to be as follows:-
This invention relates to bells for velocipedes the object being to simplify their
striking mechanism and consequently lessen the cost of their manufacture.
The said mechanism comprises two hammers carried upon a spring or springs
secured to an oscillating finger; an operating lever having a tooth or teeth or
projections thereon by means of which the finger is oscillated; and stops against
which the two parts of the spring or the springs alternately bear during the forward
and backward movement of the lever, the said spring or springs serving not only.
to carry the hammers and cause them to strike but also to bring back the finger
and hammers to their normal position.

COMPLETE SPECIFICATION.
Improvements in Bells for Velocipedes.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication to
me by Heinrich Wissner, of Mehlis Thuringia, in the Empire of Germany, Manu-
facturer) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to bells for velocipedes the object being to simplify their
striking mechanism and consequently lessen the cost of their manufacture.
The said mechanism comprises two hammers carried upon a spring secured to an
oscillating finger; an operating lever having a tooth or teeth or projections thereon
by means of which the finger is oscillated; and stops against which the two parts
of the spring alterately bear during the forward and backward movement of the
lever, the said spring serving not only to carry the hammers and cause them to
strike but also to bring back the finger and hammers to their normal position.
:-
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing in which :-
Figure 1 is a plan of a double gong velocipede-bell constructed according to
my invention, one of the gongs being removed to shew the interior mechanism, and,
Figure 2 is a section of the bell with the gongs.
Similar letters in both the figures indicate similar parts.
In the drawing I have shewn my invention applied to a double gong bell,
a, a being the gongs secured to pins & on a plate c in the usual manner.
d, d are the hammers, two of which are provided for each goug; e, e are the
springs carrying the hammers and fis the oscillating finger to which the springs e

page_text: are secured the said finger working on a stud g on the plate c; h is the operating
lever pivotted at i to the plate c, and j, j, j are the teeth or projections on the lever
which when the latter is turned on its pivot by means of the handle k in the
direction indicated by the arrow Figure 1 successively move the finger f towards
the left hand; 1, 1 are the stops against which the springs e bear. Thus when the
handle is moved in the said direction the parts of the springs e carrying the left
hand hammers by bearing upon their stops will return the finger f to its central
or normal position after the operation of each of the teeth ; thereby causing the
right hand hammers to strike the gongs a three times in succession. On the lever
handle being released the lever will return to the position shewn in Figure 1
under the action of a spring m secured to a stud n on the lever and to a stud o on
the opposite side of the plate c. As the lever returns its three teeth will
successively move the finger f towards the right hand and the parts of the springs e
carrying the right hand hammers d, will, by bearing against their stops 1, cause
the left hand hammers to strike the gongs a three times in succession thus giving
six strokes upon each gong, or twelve strokes in all, at each operation of the
lever . The play of the lever is limited by one of the pins & to which the gongs
are secured located in a slot p in the lever.
It will be obvious that the number of the teeth on the lever h may vary.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A bell for velocipedes comprising two hammers carried upon a spring secured
to an oscillating finger, an operating lever having a tooth or teeth or projections
thereon by means of which the finger is oscillated, and stops against which the two
parts of the spring alternately bear during the forward and backward movement of
the lever, the said spring serving not only to carry the hammers and cause them to
strike but also to bring back the finger and hammers to their normal position,
substantially as set forth.
2. The improved bell for velocipedes hereinbefore described and illustrated in
the accompanying drawing.
