PROVISIONAL SPECIFICATION.
Improvements in Bells for Velocipedes.
I, HEINRICH WISSNER of Mehlis, Thuringia, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows :—
My invention relates to bells for velocipedes.
According to my invention I use a double bell for velocipedes wherein two gongs
are fixed upon a vertical plate carried by a rod of the velocipede. The said plate
also carries the striking mechanism consisting of two bent hammers with springs
appertaining thereto, an intermediate lever and an operating lever by means of
which the rider actuates the hammers and thus rings the bell. When the operating
lever is pressed downwards at one end it raises with its other extremity one end of
the intermediate lever which in its turn causes one of the hammers to move.
The
operating lever then releases the intermediate lever, whereby one of the springs
operates to cause the hammer to strike against its gong. I provide another spring
for returning the operating lever to its original position after being released by the
operator. The inner extremity of the operating lever is curved so as to actuate
the intermediate lever in the opposite direction when the said operating lever is
released. The second hammer is thereby moved and thrown towards its gong by
the second spring. Thus the gongs ring alternately on pressing and releasing the
operating lever.

Improvements in Bells for Velocipedes. .
I, HEINRICH WISSNER, of Mehlis Thuringia, in the Empire of Germany,
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:-
My invention relates to double-gong bells for velocipedes, and comprises improve-
ments in the striking mechanism.
The said mechanism consists of two bent hammers with springs appertaining
thereto, an intermediate lever and an operating lever by means of which the rider
actuates the hammers and thus rings the bell.
To enable my invention to be fully understood will describe the same by
reference to the accompanying drawing, in which :-
Figure is a plan of a double-gong velocipede bell provided with my improve-
ments, one of the gongs being removed to shew the striking mechanism:
Figure 2 is a sectional elevation:
Figures 3 and 4 are views of the striking mechanism similar to that shewn in
Figure 1, except that the parts are shewn in different positions to illustrate the
operation.
indicate the two gongs of the bell, which gongs are carried upon the
spindle mounted in a plate c attached to a clip d, by means of which latter the
bell may be connected to the handle-bar or to some other suitable part of a
velocipede.

page_text: bent hammer e. jis a spring which serves to return the hammer e in its normal
position, that is to say, with its rear end in contact with the spindle b, and j' is a
spring which serves to return the hammer el to its normal position. As the rear
end of the hammer is in contact with the intermediate lever !!: it follows that the
said spring also serves to return the said intermediate lever to its normal position.
is the operating lever which is acted upon by a spring k¹.
-When
The operation of the striking mechanism is as follows, that is to say -
the outer end of the operating lever is pulled in the direction of the arrow, Figure 1,
that is, against the pull of the spring k¹, it acts with its inner end upon the adjacent
end of the intermediate lever and causes the said intermediate lever, together
with the hammer e to which it is connected, to inove as shown in Figure 3: when
the lever has been pulled far enough it moves out of engagement with the end of
the said lever g so that the latter and the hammer e are free to move back to their
normal position under the action of the spring j, the hammere at the same time
striking its gong a. As the operating lever k moves back under the action of its
spring its inner end again impinges against the end of the lever g, but, in this
case, upon the opposite side thereof to that which it previously operated upon; the
result of this is that the lever g is moved as shewn in Figure 4 to act upon the rear
end of the hammer e¹ and move the same against the pressure of its spring
that, when the lever is again released by the operating lever k, the said spring
will cause the hammer e¹ to strike its gong a' and at the same time return the lever
to its normal position, as shewa in Figure 1. It will thus be understood that cach
time the operating lever is pulled and released, first the hammer e and then the
hammer e is operated.
y
so
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 a double-gong bell for velocipedes the combination of two hammers which
are operated alternately through the medium of an intermediate lever pivotted to
one of the said hammers and with which the operating lever engages, substantially
as described.
2. The manufacture and use of a double-gong bell for velocipedes having striking
mechanism constructed, arranged and operating substantially in the manner herein-
before described and illustrated in the accompanying drawing.
