We, RUDOLF RAUSCH, Sculptor, and LUDWIG BLAUHORN, Bank Clerk, both of St.
Marx, Vienna, in the Empire of Austria, do hereby declare the nature of this
invention to be as follows:-
Alarm apparatuses for velocipedes as hitherto constructed have the disadvantage
that the rider must loosen his grip of the steering handle in order to put in action the
alarm, whereby the stability of the machine is reduced at the very moment when
careful steering appears most necessary.
The present invention has for its object to obviate this disadvantage by the
arrangement of an alarm apparatus which, by the rotation of one of the handles on
the steering har, will be put in operation and thus render unnecessary the loosening
of the grip on the steering handle.
The following is one method in which we carry the invention into effect.
On the end of the handle bar is a handle, which is provided with a metal bush
capable of revolving and which is fixed toward its outer end to a toothed ring. The
bell is placed on the outer end of a spindle, which is fixed to a casing placed over one
end of the handle bar and soldered or otherwise fixed thereto. The spindle carries a
hinge for the hammer, the hinged block or carrier of which is pressed, by means of
a spring, constantly against the aforesaid toothed ring. To the outer end of the
handle is attached a bell-shaped protecting casing. When required the handle will
be revolved in one or the other direction around the handle-bar and move the toothed
ring with it, whilst the spindle will hold the bell and the hammer-carrier stationary.
By these means the hammer receives an oscillating movement by the indentations of
the ring and the bell is caused to ring.
Instead of the hammer remaining stationary and the operating ring being made
movable, the spindle may, on the contrary, carry the bell and the hammer and be
attached to the movable handle, whilst the toothed ring may be attached to the
handle bar.

ascertained in and by the following statement:-
Alarm apparatus for velocipedes as hitherto used have the disadvantage that the
rider must loosen his grip of the steering handle in order to put in action the alarm,
whereby the stability of the cycle is reduced at the very moment when careful
steering appears most necessary.
The present invention has for its object to obviate this disadvantage by the
arrangement of an alarm apparatus which by the rotation of one of the handles on
the steering bar, will be put in operation and thus render unnecessary the loosening
of the grip on the steering handle.
In the annexed drawing are shown two forms of construction of such an alarm
apparatus.
Fig. 1 shows the apparatus in a longitudinal section.
Fig. 2 is an end view, the bell being taken off whilst Figs. 3 and 4 are two
similar views of a modification.
The handle b provided with an interior metal socket 61 turns on the end of the
steering rod a, this handle b being fixed to a toothed ring c. The bell d is scated
on the exterior end of a spindle d' which is fixed on a socket a' slid over the end of
the steering rod and brazed or otherwise fastened thereto.
The spindle d' carries a hinge joint de for the hammer which is pressed
continuously by a spring f with its tooth f against the toothed ring c. On the
handle bis arranged a bell shaped protecting socket 2.
When used the handle b is turned in the one or the other direction round the
steering rod a and turns the toothed ring c whilst the spindle d with the bell d
and the hammer f remains stationary. The hammer f thus receives an oscillating
movement by the action of the teeth of the ring c and strikes the bell.
Instead of making the support of the hammer stationary and the driving ring c
movable, as shown in the drawing, the spindle d' with the bell and the hammer f might
also be connected with the rotary handlo, whilst the toothed riug c is fixed on the
steering rod.

In the modification shown in Figs. 3 and 4 the bell d is not arranged on the
exterior, but on the interior end of the handle 6 and is also sounded by turning the
latter. The aların mechanism shown in Figs. 1 and 2 can be used for this purpose
or in its place the following device. Over the steering rod a is slid a socket
which on both ends, are soldered short lengths of tubes rand of which serves
as bearing for the bell and prevents the handle from falling off. On the tube "
is soldered a disk s which carries the known aların mechanisu, and under which
a disk u is provided, with which by means of screws t the toothed wheel z is
connected. By turning the handle, which is cemented on a metal tube m the toothed
wheel is turned and the spring operated hammer is driven against the bell.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. An improved alarm apparatus for velocipedes having a handle b adapted to
turn round its longitudinal axis on the steering rod a and giving during its rotation
an oscillating movement to the hammer f and thus sounding the bell d arranged
at the outer or inner end of the handle.
2. In an alarm apparatus as described in Claim 1. a toothed ring o which
is fixed on the rotary handle ba hammer pressed by means of a spring
against the teeth of this ring c and a bell d connected fixedly with the end of
the steering rod.
3. In an alarm apparatus as described in Claim 1 a toothed wheel connected
with the rotary handle on its interior end driving by its rotation the spring operated
