Improvements in Bells for Velocipedes.
I, PAUL SCHILLING of Mehlis in Thüringen, Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows :-
This invention relates to a double bell for velocipedes the operation of which is
such that by actuating a single handle, first one dome and then the other dome will
sound.
A double bell according to my invention is illustrated in the accompanying
drawings, in which,
Fig. 1. is a vertical section on the line B B Fig. 3.
Fig. 2 is a front elevation with the domes removed.
Fig. 3 is a horizontal section on the line A. A Fig. 1, and
Fig. 4 is a part elevation corresponding to Fig. 1. but shewing the operating
levers in another position.
The two drums and are fixed on a fork-shaped upright a centrally above
one another in such a manner that the outer dome e partly covers the inner one b.
The upright a is fixed on the velocipede frame by means of an angular clamping
piece and screw hook e. The screw hook e is tightened by means of a nut h
which has a wide round foot h' that engages in a groovey and it is thus prevented
from falling out when it is being unscrewed. is the hammer for the inner dome

Improvements in Bells for Velocipédes.
I, PAUL SCHILLING of Mehlis in Thuringen, 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:-
This invention relates to a double bell for velocipedes the operation of which is
such that by actuating a single handle, first one dome and then the other dome will
be sounded.
.
A double bell according to my invention is illustrated in the drawings, left with
my Provisional Specification, in which,
Fig. 1 is a vertical section on the line B B Fig. 3.
Fig. 2 is a front elevation with the domes removed.
Fig. 3 is a part horizontal section on the line A A Fig. 1, and
Fig. 4 is a part elevation corresponding to Fig. 1 but shewing the operating
levers in another position.
a is a fork-shaped upright on which two domes and are fixed these being
arranged centrally above one another in such a manner that the outer dome c
partly covers the inner one b. The upright a is fixed upon the velocipede frame
by means of an angular clamping piece and screw hook e. The screw hook e
is tightened by means of a nut h, which has a wide round shoulder that
engages in a groove g, and which is thus prevented from falling out when it is
being unscrewed. is the hammer for the dome and the hammer for the outer
dome c.
The hammer is mounted on a lever m which is capable of being rotated
about a pin on the arms a' of the upright; it is provided with a handle n and is
held by a spring o in a state of tension in the position shown in Fig. 1.
The lever is provided on its front side with an upwardly bent tongue p which
serves to actuate the hammer i for the inner dome as presently explained.
The lever q of the hammer i is capable of rotation about a pin on the arms a²
of the upright, and carries at its rear end g', two lateral tappets s between which a
shoe is capable of moving. A spring serves to keep the hammer-arm in the
position shown in Fig. 1, and a spring serves to keep the shoe t pressed upon the
fever 4.
The shoe is formed with a rear extension which engages
with
the bent end p of the lever m, but springs back when the end p of that lever has
moved over and the handle m has been released.
The mode of operation is as follows:-
When the lever mis pressed downwards by pressure upon the handle n, the
upwardly bent end p bears against the underside of the rear end of the shoet.
Now since the shoe t is connected by means of the tappets s with the lever q,
the latter is raised at its rear end by the descent of the hammer i. This continues
until the upwardly bent end p of the lever m releases the end of the shoe (Fig. 4)
whereupon the shoe end actuated by the spring again falls down, and the
hammer i (in consequence of the hammer arm 7 striking against the arms a of
the fork frame a) springs against the inner dome and causes it to sound. Upon
the arm being still further depressed by pressure upon the handle n, and being
then released, the hammer k will fly up against the outer dome and strike it.
The front end p of the lever m will thereupon move downward, moving past the
shoe end of the shoe t, since the shoe t can rotate about the pin sin the tappets s,
thus placing the spring v in tension. When P has moved past the shoe t, the
shoe will fly back again under the action of the spring v.

page_text: 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 a velocipede, having two domes the striking hammers of which are
operated from one handle, such as described.
2. A bell for a velocipede, having two domes, the striking hammers of which
are operated by a single lever (m) the arrangement being such that when the
operating lever is actuated its rear end (p) will first operate the lever (7) of the
hammer (i) of one dome (6) through the medium of a shoe () and then release
the levers () in such a manner that the hammer (i) will strike the dome (b,)
and the release of the lever (m) will cause the second dome to sound substantially
as described.
3. In a bell of the kind referred to in Clain 1, the shoe (¹) arranged so as to
be capable of rotation on the rear end (g) of the hammer-lever (7) operated by
the lever (m), in combination with the spring (e) for pressing the said shoe (t )
upon the lever (2), the arrangement being such that the latter can be raised by the
lever (m) but remains uninfluenced in its position when the lever (m) moves down
into its normal position, substantially as described.
4. In a bell of the kind referred to in Claim 1, a clamping piece having a
groove (g) to receive a shoulder (41) on the nut (4) substantially as described for
the purpose specified.
