ATION.
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 both simple and certain in their action and less liable to become
derranged in use.
My bell or alarm is formed by two main portions the base piece which has an
upward flange at its edge and the bell which covers or is mounted over the base
piece. Upon the centre of the base piece I mount or fasten a pillar in a centre
hole upon the lower portion of which I hang a toothed pinion and also a toothed
wheel above the pinion and these may be fast together. The thumb or finger lever
projects through a part of the turned up flange being pivotted near the edge of the
base piece and 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 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 spring. Gearing into the wheel is a small
pinion working upon a side post and above this pinion, the hammer for striking the
bell is mounted. This hammer is oblong or oval in shape having a slot running
lengthwise and it is mounted upon the post or pin carrying the side pinion so that
as the pinion is revolved by the large wheel operated by the lever and spring, the
hammer strikes the inside of the bell rapidly and with distinct blows as it
reciprocates at each blow upon the pin by the slot before mentioned. The bell is
screwed upon the top of the centre pillar.

COMPLETE 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 inven-
tion, 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 both simple and certain in their action and less liable to become
derranged in use.
My bell or alarm is formed by two main portions the base piece which has an
upward flange at its edge and the bell which covers or is mounted over the base;
piece, upon the centre of the base piece I mount or fasten a pillar in a centre hole"
upon the lower portion of which I hang a toothed pinion and also a toothed wheel
above the pinion and these may be fast together. The thumb or finger lever
projects through a part of the turned up flange being pivotted near the edge of the
base piece and the inside end of the lever carries a toothed quadrant which gears

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 spring. Gearing into the wheel is a small
pinion working upon a side post and above this pinion the hammer for striking the
bell is mounted. This hammer is oblong or oval in shape having a slot running
lengthwise and it is mounted upon the post or pin carrying the side pinion so that
as the pinion is revolved by the large wheel operated by the lever and spring, the
hammer strikes the inside of the bell rapidly and with distinct blows as it
reciprocates at each blow upon the pin by the slot before mentioned. The bell is
screwed upon the top of the centre pillar.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a sheet of drawings upon which I have
illustrated an example of my invention which will be sufficient to make the principle
known to others. It will be readily understood that the general design and
arrangement may be modified without departing from the principle of the
invention.
Figure 1. is a general external view of one of my bells complete.
Figure 2. is a cross part section and part elevation of the same bell as shown
by Figure 1 but showing the internal mechanism.
Figure 3 is a plan with the upper or bell portion A. removed so as to show the
mechanism clearly as mounted upon the base B.
Figure 4 is a plan and side view of the new hammer H.
Figure 5 is a sectional plan of the pinion w' showing the flat neck w upon which
the hammer H is mounted and loosely slides.
The bell A is as usual mounted upon a spindle E attached to the base B with
the striking mechanism consisting of the lever L which is one with the quadrant Q
gearing into the pinion g' fast with the spur wheel W both of which turn or
revolve upon a neck of the spindle E with W gearing into the pinion to which
revolves upon the pin P the pin P being fast to the base B. The lever L and
quadrant Q are kept in a normal position by a spring S to which I lay no claim.
My hammer H as seen in detail at Figures 4, is oval or oblong with a slot
hole which fits loosely upon the projections to wo formed on the pinion w
which prevents the hammer H from turning round except with the pinion to³.
As the pinion to is rapidly revolved by the lever L and mechanism the
hammer is constantly thrown against the inside of the bell with a succession of
blows which take place both as the lever L is thrust outwards by the hand and
as it returns inwards by the spring S and thus the alarm is produced most
effectively. I may mount a spiral or other spring above the collar p' on P but
if not P may be shorter than shown.
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
1st. The improvements in bell alarms for cycles and other uses consisting of
the bell A mounted upon its base and capable of being operated upon by the
hammer H substantially as herein set forth and as shown upon the accompanying
drawings.
2nd. In bell alarms the combination of the parts A with the mechanism
mounted upon B operating and in combination with the hammer H substantially
as set forth and illustrated.
3rd. In bell alarms the use of the hammer H substantially as herein described
and shown.
