page_text: I, JOSEPH TAMBOUR, of II Mathildenplatz No. 5, Vienna, Austria, Official, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of bell for cycles and appliances
for actuating the same as follows.
A base plate, secured by a clamping device in the usual manner either to the
handle bar or other part of the cycle frame, or preferably to the tubular rod of the
brake, carries a single or double dome-shaped bell mounted on a central stem, on
which, within the bell is mounted loose a two armed lever carrying sliding or
spring strikers which on the rotation of the lever are thrown outward by the
centrifugal action and strike projections on the bell or belle. The arm is con-
nected through toothed multiplying gear with a pinion, also loose on the central
stem, with which gears a toothed rack sliding in guides on the base plate and
having a stem projecting beyond the bell, which stem is either actuated by hand for
ringing the bell or is otherwise actuated on applying the brake as will be presently
described.
up
When fixing the bell to the tubular brake rod, the base plate of the bell has
two projecting screws passing through a clamping plate, so that on passing the
brake rod between the bell and the clamping plate, and tightening the latter
by nuts on the screws, the bell is clamped on to the brake rod, while the stem
projecting from the toothed rack of the bell projects downward and is attached
to a looped wire bracket that is clamped on to the steering fork or its rod, and
that may also constitute the lamp carrier. Thus on actuating the brake lever for
applying the brake the brake rod will move the bell downward, and the stem of
its rack being fixed, the rack will be caused to rotate the gearing of the bell, and
sound the latter.
Or the reverse arrangement may be employed, that is to say, the bell be clamped
on to the steering fork, and the upward directed stem of the toothed rack be
connected to a clamp on the brake rod, so that on the depression of the latter, the
rack will be actuated so as to ring the hell. In order to enable the bell to be so
adjusted that it will not be rung when the brake is applied, the stem of the rack,
instead of being fixed to the said bracket clamped on the steering fork or on the
brake rod, as the case may be, is provided with a sliding piece that can either be
fixed by a setting screw so as to nip the said bracket between it and a fixed head
on the end of the rack stem, or it can be slid away from the bracket so that the rack
stem is not attached to the latter.

of the gong, which is thus sounded.
A helical or flat volute spring attached at one end to the rack q and at the other
end to the plate a effects the motion of the rack in the one direction.
The bell is attached either as usual to the handle bar or cycle frame, or preferably
the bell is arranged to be operated in connection with the brake mechanism, as
shewn at Figs. 3, 4, 5 and 6. In this case the base plate a carries two screws gh
which at the same time serve as axis to the wheel f and as guide to the rack
and to the back of the plate a is fixed a saddle piece r; the screws g h pass through
a clamping plate rl and are provided with screw-nuts s s¹.
By these means the bell is clamped to the brake rod of the cycle, as shewn at
Fig. 5.
The projecting tail of the rack bar q is formed with a T head and carries a
sliding piece t with correspondingly shaped head, and which is adjustably secured
to the slotted end of 9 by a screw nut t¹ on a threaded pin u.
The heads of q and t are made to embrace a wire bracket 2, shewn detached
in plan and side view at Fig. 7, which is formed of a loop shape as shewn, and
which is clamped upon the steering fork by means of a screw and nut w w¹. This
bracket may also be so formed as to constitute the support for the lamp, as indicated
at Fig. 8.
Thus on depression of the brake rod for applying the brake, the bell will be
moved downward while the rack q is held stationary and consequently the 'bell
will be sounded.
It will be seen that by loosening the screw nut t¹ so that the piece t can slide
on the rack bar q, the bell will not be sounded on depressing the brake rod.
The arrangement can also be reversed as shewn at Fig. 6, the bell being carried
by the bracket, suitably bent up for the purpose, while the rack bar q is clamped
to the brake rod y, so that the rack q is moved on applying the brake, the bell
being stationary. Figs. 9, 10 and 11 shew a perspective view, a side view and a
plan of another form of the bracket 2, for clamping the same on the two limbs
of the steering fork, being provided with clamping rings for this purpose.
The above described bell and its attachments can be readily applied by any one
to his bicycle; owing to its position, it is protected from injury in the event of
falling, and should any part be damaged it can be readily replaced.
pro-
If the cycle has no brake, the bell is attached to the steering tube and the
jecting tail of the rack q is arranged in an inverted manner so that its end, provided
with a button, can be operated by the hand, while holding the handle bar.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In a bell for cycles, the combination with a base plate a of a sliding toothed
rack geared by means of toothed gearing p f with a toothed sleeve 0, loose on
a central pin, and having radial arms on which are sliding blocks or balls which on
the rotation of the arms by the motion of the rack, are thrown by centrifugal action
against projections on the gong of the bell, so as to sound the same, substantially
as described.
2. In a bell constructed as set forth in the first claim, adapting the outer end of
the rack bar q to be connected to a bracket attached to the steering tube or fork
while the bell is attached to the brake rod by a clamping device, substantially as
described.
3. In a bell constructed as set forth in the first claim, adapting the rack bar q to
be attached to the brake rod while the bell is attached to a bracket on the steering
tube or fork, substantially as described.
4. In the arrangement of the bell referred to in Claims 2 and 3, effecting the
attachment of the rack bar q by means of a clamping piece t secured by a screw
