PROVISIONAL SPECIFICATION.
Improvements in Bell Alarms for Cycles, and other Uses.
I, ALFRED DE COURCY, of Mary Street Saint Paul's, Birmingham, in the County
of Warwick Manufacturer, do hereby declare the nature of my said invention to
be as follows:-
My invention has for its object improvements in bell alarms for cycles and
other uses which are simple and certain in their action and less liable to become
out of order when in use.
In carrying my invention into practice I form my bell or alarm in two main
portions the base piece which has an upwardly turned flange at its edge and the
bell or gong which covers and is mounted over the base piece. Upon the centre
of the base piece I mount or fix a centre pillar upon the lower the lower portion
of which I place a toothed pinion and also a star wheel above the pinion which
is fixed thereto. The thumb or finger lever projects through a part of the turnedi
up flange and is pivoted close to the edge of the base piece the inside end of the
lever carries a toothed quadrant which gears into the pinion. A spring is connected
to the base of the quadrant and to the hase piece which keeps it normally to one side
so that when it is pushed a double action is produced by the quadrants return which
is due to the action of the spring. Mounted on a side post and working into the
star which is a double winged trembling piece and also mounted on the side post
above the trembling piece is a hammer for striking the bell the back end of the
hammer being pivotted to the back of the trembling piece. One of the points of
the star wheel are formed larger than the others so that it abuts against one of the
wings of the trembling piece and prevents the parts from rattling. When the pinion
wheel is revolved by the quadrant operated by the lever and spring it causes the star
wheel to oscillate the trembling piece and consequently the hainmer which strikes the
inside of the bell rapidly and with distinct blows.

Improvements in Bell Alarms for Cycles, and other Uses.
I, ALFRED DE COURCY, of Mary Street, Saint Paul's, Birmingham, in the County
of Warwick, Manufacturer, do hereby declare the nature of my said 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 has for its object improvements in bell alarms for cycles and other
uses which are simple and certain in their action and less liable to become out of
order when in use.
My bell or alarm is formed in two main portions, the base piece which has an
upwardly turned flange at its edge and the bell or gong which covers and is

page_text: mounted over the base piece. Upon the centre of the base piece I mount or fix
a centre pillar, upon the lower portion of which I place a toothed pinion and also
a star wheel above the pinion which is fixed thereto. The thumb or finger lever
projects through a part of the turned up flange and is pivotted close to the edge of
the base piece; the inside end of the lever carries a toothed quadrant which
gears into the pinion. A spring is connected to the base of the quadrant and to
the base piece which keeps it normally to one side so that when it is pushed a
double action is produced by the quadrant's return which is due to the action of the
spring. Mounted on a side post and working into the star wheel is a double
winged trembling piece, and also mounted on the side post above the trembling
piece is a bammer for striking the bell, the back end of the hammer being
pivotted to the back of the trembling piece. One of the points of the star wheel
is formed larger than the cthers so that it abuts against one of the wings of the
trembling piece and prevents the parts from rattling. When the pinion wheel is
revolved by the quadrant operated by the lever and spring it causes the star
wheel to oscillate the trembling piece and consequently the hammer which strikes
the inside of the bell rapidly and with distinct blows.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a double sized sheet of drawings upon
which I have illustrated examples of my improved bell alarm. It will be readily
understood that the general design and arrangement may be modified without
departing from the principle of the invention.
Figure is a general external view of one of my bells complete.
Figure 2 is a cross part section and part elevation of Figure 1 showing the
internal mechanism.
Figure 3 is a plan view with the gong or bell removed, so as to clearly show
the mechanism mounted on the base.
Figure 4 is a plan view of the star wheel.
Figure 5 is a plan view of the winged trembling piece.
The bell A as usual is mounted upon the pillar P attached to the hase B, and
apon the lower portion of this pillar I place the toothed pinion ci which is fixed
to the star wheel C. The lever L, on one end of which is formed the quadrant Q
is pivotted at l¹ to the base and gears into the pinion cand this lever and quadrant
is kept in its normal position by the spring S which is secured to the turned up
flange b'. The winged trembling piece D is mounted upon the side post d' fixed to
the base and is provided with the recess into which the teeth or points of the star
wheel work. Also mounted on this side post and pivotted at to the back of the
trembling piece is the striker or hammer H for striking the gong or bell. The
strengthening piece 4' is mounted on the side post and on the pillar P so as to ensure
the star wheel and trembling piece being always kept in proper position. To sound
the gong the lever is pulled outwards by the hand and returns inwards by the action
of the spring, thus rapidly revolving the pinion and star wheel, thereby imparting an
oscillating motion to the winged trembling piece, by which means the hammer is
caused to rapidly strike the inside of the bell or gong. To lasten my bell to the
bandle bar of a velocipede or other article I form my clip from the spring steel
band F and pivot or hinge it at fl to the bracket G which is fixed to the base of the
bell. This spring clip may be tightened around the part to which it is attached by
the set. screw as shown at Higure 1 or by the nut working on the screwed pin
which is fixed in position by the end g of the bracket as shewn at Figure 6. Instead
of the nut 1 may use a wing nut if desired.
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 :-
CLAIMS.
First. The improvements in bell alarms for cycles and other uses consisting

page_text: piece such as D or its equivalent for operating the hammer such as H in the-
manner substantially as herein before described and as shown upon the accompanying
sheet of drawings.
Second. In bell alarms the combination of the mechanism mounted on the base B.
for operating the hammer in the manner substantially as hereinbefore described and
as shown upon the accompanying sheet of drawings.
