Improvements in or applicable to Bells for Velocipedes.
I, CARL LOHMANN, of 22, Jewin Street, in the County of London, Merchant,
do hereby declare the nature of this invention (a communication from Heinrich
Wissner, of Mehlis Thuringia, in the Empire of Germany, Manufacturer,) to be
as follows:-
This invention relates to the combination with a single or double striking bell or
trilling alarm for velocipedes of an attachment whereby the bell can when required
be used as a jingler or trembling bell.
In carrying out the invention I apply upon the stem of the bell a movable
arm adapted when operated by the rider to clip a jingling or trembling hammer
and keep it from striking the gong, or to free the said hammer as required,
a suitable stop being provided to retain the arm in either of its two positions.

COMPLETE SPECIFICATION.
Improvements in or applicable to Bells for Velocipedes.
I, CARL LOHMANN, of 22, Jewin Street, in the County of London, Merchant,
do hereby declare the nature of this invention (a communication from Heinrich
Wissner, of Mehlis Thuringia, in the Empire of Germany, Manufacturer,) 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 the combination with a single or double striking bell or
trilling alarm for velocipedes of an attachment whereby the bell can when required
be used as a jingler or trembling bell.
In carrying out the invention I apply upon the stem of the bell a movable arm
adapted when operated by the rider to clip a jingling or trembling hammer and
keep it from striking the gong, or to free the said hammer as required, suitable
stops being provided to retain the arm in its two positions.
To enable the said invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a sectional elevation of a single gong bell provided with the improve-
ments, and
Figure 2 is a similar view but shewing some of the parts in different positions.
Figure 3 is a plan of the bell with the gong removed, and
Figure 4 is a section on the line 4, 4, Figure 1.
a is the stem of the bell provided at one end with the clip b, c is the gong
attached to the said stem and d is a spring hammer pivotted at e to the plate f
all of which parts being of well known construction require no further description.
is the trembling hammer which is suspended from the plate f and the shank
of which is preferably composed of a spiral spring which is arranged as shewn in
Figure so that normally the said trembling hammer will be in such close
proximity to the gong that the said gong will be struck by the said hammer when
g
the latter vibrates.
h is the movable arm or lever pivotted upon the stem at i and at one end j shaped

page_text: to partially encircle the stem of the hammer g as shewn most clearly in Figure 3.
The other end of the lever h is adapted to engage in a notch in a lever m
pivotted to the stem at n in such a manner that the movement of the lever m will
cause the movement of the lever h.
With this arrangement it will be understood that when the levers and m
are in the position shewn in Figure 1 the hammer 9 will be free to strike
the gong, whilst when the said levers are in the position shewn in Figure 2
the said hammer g will be held or gripped so that it cannot strike the gong.
In order to retain the levers in either position as required I advantageously.
provide spring stops o, o in the stem a. Each of these stops consists of a headed
stud located in a suitable recess and acted upon by a spring to force its head into
a hole in the corresponding lever as shewn in Figure 4. In the drawing these
stops are so placed that one acts when the levers are in one position and the
other when they are in the reverse position.
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 velocipede bell having a trembling hammer arranged as described and
adapted to be released and gripped substantially as set forth.
2. The manufacture and use of the improved velocipede bell hereinbefore
described and illustrated in the accompanying drawing.
