I, FRANZ MESSEDAT, of Aachenerstrasse 21, Cologne, in the Empire of Germany,
Merchant, 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 an improved alarm revolver principally for the use of
cyclists.
In the annexed drawing, Figs. 1 and 2 show this revolver in plan view, the cover
being removed. Fig. 3 is a cross section on line x-x of 'Fig. 1, and Fig. 4 is a side
view. Fig. 5 shows a detail of the construction.
Cyclists are often attacked by dogs and thus exposed to danger. In order to avoid
such danger the present revolver is intended to be used with blank cartridges in order
to scare away dogs.
The revolver arranged at a convenient place, preferably on the steering handle / of
the cycle consists of the plate a wwer which there turns the cartridge chamber b
provided with teeth b' and 62 on its upper border and on its circumference.
This cartridge chamber 6 is shown in the annexed drawing as capable of receiving
10 cartridges.
With the teeth 62 there engages a dog c under the effect of a spring c¹ and hinged
on an arm & of a lever d d¹ pivoted at d².
The arm d¹ projecting beyond the bed plate serves as a handle. On the arm d
there operates a spring d³, which tends to keep or return in or to the position shown
in Fig. 1, on pulling the arm d¹ the arm d moves from the position shown in
Fig. 1 into that of Fig. 2, the cartridge chamber b is turned one tooth 62 further and
the spring d³ is brought into tension on letting the arm d¹ go, the spring d³ brings
the dog c as well as the levers d d back into their original position (Fig. 1)
and the spring c¹ brings the nose of the dog c again into engagement with the next
tooth 6º.
The striking pin f causing the explosion of the cartridge and provided with a
point f, is guided in a bracket e and also in the arm i which is attached to the
striking pin of which the pin f projects downwards below the under surface of the
armi. The arini is displaceable, in a slot e¹ in the back wall of the bracket & and
lies with a conveniently formed surface on the bent surface of a tooth b¹ of the
cartridge chamber b. When turning the latter by means of the lever d d¹ the
tooth being in engagement with the, inclined surface of the arm i lifts the arm i
causing it to slide upward in its slot lifting the pin f and bringing the spring fon
the pin f into tension. After the point of the tooth has passed from under the
surface of the arm i, the latter is driven down by the spring f the pin f moving
down with it and a cartridge is thus exploded by means of the pin f. The shell a
has under the striking pin ƒ an opening a¹ (Fig. 5) for passage of the wad and
powder gases from the cartridge. Laterally from this opening a there are provided
conveniently also one or more openings in the shell a to allow of pushing the cartridge
cases out from below.

page_text: By displacing the angular lever h pivoted on the support e by hand (after removal
of the bell g) the arm i can be lifted and remain upheld on the end of the lever, so
that the revolver is out of action.
The whole arrangement is enclosed by a casing g, which is formed suitably, as a
bell. The latter is connected in a detachable manner by means of the spring g¹ with
the shell a; the bent ends g² engaging recesses in the casing a and being detachable
by means of the pin g³. The bell g is operated by the lever m provided with handle
and hammer and serves simultaneously as alarm bell.
The filling of the chamber with cartridges and the removal of the empty cases can
be done after taking off the bell g. This removal is very simple and it is sufficient
to press by means of the pin, g³ the one bent end g² of the spring g¹ out of its recess,
in order to be able to take off the bell.
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. An alarm revolver principally for the use of cyclists in which the cartridge
chamber b pivoted on a shell a is provided with teeth 62 for turning the chamber b
by means of the lever d d¹ and dogs e and also with teeth b¹ for lifting the striking
pin f and bringing into tension the spring f² thereof.
2. A revolver as in Claim 1, wherein the mechanism is enclosed in a detachable
casing, formed. as an alarm bell..
Dart is on day of May 1990.
