We, VEIT RIPPERGER, of No. 6, Moritzwallstrasse, and HEINRICH KÖNIG, of No. 7,
Mittelstrasse, both of Erfurt, in the Empire of Germany, Mechanics, do hereby
declare the nature of this invention to be as follows:-
The apparatus which forms the subject of the present invention and which is
fixed upon the velocipede, serves as a protection from the attacks either of men or
animals, more especially the latter by enabling the immediate discharge of detonat-
ing caps or the like arranged upon an endless strip to be effected whenever desired.
In one constructional form or modification of the apparatus a detonating hammer
is fixed upon the end of a spring and is raised by the action of a bevelled portion
of the hand-or operating lever, upon a stop secured to the side of the hammer,
the said hammer striking upon a block or anvil as soon as the bevelled part has
passed beneath the said stop. To one end of the hand or operating lever is pivotted
a short lever, having a laterally projecting pin or stud at its opposite end. Upon
this hand lever being pressed forward, the said laterally projecting pin or stud
passes between a fixed guide plate and a spring strip-guiding plate, under the
action of a spring acting upon the upper edge of the said short lever and carries
with it the strip of detonating caps or the like, which may be wound up in the
form of a roll. When the hand lever moves back the pin or the said short lever
slides above the fixed guide plate under the action of a spring below the said short
lever, whilst the hand or operating lever by reason of the lateral displacement
of the same upon its pivot against the action of a spring on said pivot, clears the
stop on the side of the hammer.
In another constructional form we may use instead of the fixed guide plate
a spring-plate and a bent lever, the arm of which is raised by the hammer in the
forward movement and presses the other arm against the spring plate and con-
sequently the laterally projecting pin against the strip and guide plate whilst
upon the return movement the said pin moves freely between the spring plate
and the guide plate. In order that the bevelled part of the hand lever may pass
by the stop on the hammer the said hammer is pressed to one side.
The apparatus is covered with a projecting cap which may likewise serve as a
bell. The spring bow fixed thereon engages in recesses in the base plate and
enables the dome to be readily removed for the purpose of renewing the detonating
strip.

We, VEIT RIPPERGER, of No. 6, Moritzwallstrasse, and HEINRICH KÖNIG, of No. 7,
Mittelstrasse, both of Erfurt, in the Empire of Germany, Mechanics, do hereby
declare the nature of this invention and in what manner the same is to be por-
formed, to be particularly described and ascertained in and by the following
statement:
The alarm device which forms the subject of the present invention and which
is adapted to be fixed to cycles, enables detonating caps arranged in the form of a
band or strip to be fired when desired to prevent the attacks of men or animals
and more especially the latter.
My improved alarm apparatus is shown in the accompanying drawing, in which
Figure 1 is a plan of one form of my improved device.
Figure 2 is a side elevation of the same.
Figure 3 is a plan of another form of the device.
Figure 4 is a side elevation of a portion of Figure 3.
Figure 5 is a plan of a further modified form of the device, and
Figure 6 an elevation of a portion thereof.
As shown in Figures 1 and 2, an anvil a is arranged on a base plate A which
may be fixed to any convenient part of the cycle, over which anvil is guided the
end of the detonating strip y, which is in the form of a roll. Detonation takes
place by the striking of the hammer fixed to the spring f, upon the anvil a.
This hammer is raised by the action of the rounded portion z of the operating
lever g upon a stop n, the said hammer striking the anvil a under the action of
the spring as soon as the rounded part of the lever g has passed under the said
stop n, in moving in the direction indicated by the arrow in Figure 1.
To enable the operating lever g to be returned to its original position without
lifting the hammer, the stop n is bevelled downwards from left to right, so that
the said lever will slide over the said stop n. The lever g is for this purpose
made displaceable on its axis m and is continually acted upon by a spring v as
shown in Figure 2. When therefore the lever is moved backward or in the
direction opposite to that indicated by the arrow in Figure 1, it will be displaced
along its axis m and compress the spring which will react to force the lever to
its original position immediately it leaves the stop n, the hammer in the meantime
remaining stationary.
The feeding of the detonating strip is effected by the backward and forward
motion of the lever g, as shown in Figures 1 and 2. For this purpose a small
lever is pivoted to the upper end of the operating lever g, the opposite end of
said small lever being provided with a laterally projecting pin u which bears
upon the detonating strip y, passing over the spring plate ? connected with tho
anvil a.
passes
At the commencement of the feeding operation, the pin u of the lever
over the fixed guide piece b, and presses upon the detonating strip y under the
action of a small spring q', fixed on to the lever g. If now the said lever g is acted
upon, the pin u on the lever slides between the guide b and the spring plate p
and carries the detonating strip with it. When the lever g is at or near the end
of its movement, the angle between the said lever and the lever will be such that
a second small spring fixed to the said lever g will engage with the underside
of the lever / so that immediately the lever u leaves the guide b the said spring
will press the lever upwards into such a position that in the return movement

page_text: of the lever g the pin u will move over the top of the guide b, and will, after
passing this guide again rest upon the detonating strip y when the above described
operation may be repeated.
In the modification shown in Figures 3 and 4 the alternate pressing of the
pin u against the detonating strip y, and the release of the same therefrom is
effected by replacing the guide 6 by a second spring plate i, arranged at such
a distance from the plate pas to leave sufficient space for the pin u to move freely
between the said springs i and p. When the hammer his lifted, by means of the
lever git acts upon the armi c of a bell-crank lever d pivoted to the plate A and
causes the other arm n¹³ of said lever to press upon the spring plate i so as to grip
the pin u between the said spring plate i and the spring whereby the detonating
strip will be fed forward to bring another cap into position below the hammer.
After the striking of the hammer, the spring plate will resume its original
position so as to allow the pin u to pass back without acting upon the detonating
strip y
P
In the modification shown in Figures 5 and 6 the curved portion z of the lever g
is formed on the lever which is pivoted to the said lever g at its upper end
as at s. A spiral spring q for drawing the said lever g back is attached at one
end to the pin u on the lever and at the other end to a point r fixed to the
plate A, the parts being so arranged that, when the curved part of the lever 7
is out of contact with the bevelled stop n the points r, and s lie in a straight
line, and the pin u will then be lifted out of contact with the detonating strip.
When, however, the surface of the lever is pressed against the stop u by the
forward motion of the lever g in lifting the hammer h, the said lever will be
turned on its pivot s, owing to the pressure of the hammer spring f, until the
pin u comes into contact with the detonating strip y which will be fed forward
by the said pin u until the hammer is lifted.
The apparatus is covered for the purpose of renewing when necessary the
detonating strip, with an easily removable protecting cap, which when suitably
arranged and provided with a striking device, can serve also as a signal bell.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
-
1. An alarm apparatus for cycles, for giving detonating signals, consisting of
a lever g, worked from the outside, which operates a hammer h, fastened to a
spring f, by the engagement of the lever with a stop n on the said hammer h,
the latter striking the detonating cap of the strip y on the anvil a when the
stop n is released by the said lever g, the said strip being, prior to each stroke,
fed forward by the lever 1, furnished with a pin u and pivoted to the said lever g,
in such a manner that the pin u is forced during the forward motion, by the
action of the springs q', between the fixed guide band the spring plate p, con-
nected with the anvil a so as to feed forward the detonating strip y, while during
the backward motion the pin u, under the action of the spring 2, slides over the
guide b without touching the said strip y, the said lever g in this backward
movement passing over the bevelled stop pin n and being displaced laterally
against the action of a spring substantially as described.
2. In a device of the kind referred to in the first claim a modified form of
feed for the detonating strip consisting of a plate i acted upon by one arm n²
of the bell-crank lever d the other arm c of which rests upon the hammer h,.in
such a manner that, when the hammer is lifted, the arm n¹ of the bell-crank
lever is pressed against the said spring plate i so as to cause the pin u to
engage with the detonating strip y substantially as described.
3. In a device of the kind referred to in the first claim a modified form of feed
for the detonating strip comprising a lever / having a curved part z for engaging
with the stop n of the hammer in such a manner as to cause the said lever / to

page_text: turn on its pivot s and thereby move the pin u into engagement with the
detonating strip which will be carried, forward with the said pin u; while, after
the hammer has been released the pin u is raised from the detonating strip, and
kept from engagement therewith during the return movement by the spring q
connected to the pin u, which spring serves at the same time for effecting the
return movement of the lever g, substantially as described.
