COMPLETE SPECIFICATION.
Improvements in Automatic Cut-offs for Gas, Electric, and
other Conduits.
We, JULIUS KLEINE and FRANZ LINDNER, both of 25, Potsdamer Strasse,
Berlin, Kingdom of Prussia, German Empire, Manufacturers, 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 a device for automatically checking a gas, electric, or
other conduit after the latter has been open for a certain definite time, so that the
medium conveyed by the respective conduit can be consumed but for that time;
and the object of our invention is, first, to hinder an unduly long use of the
respective medium, and, second, to prevent the arising of accidents-by leakages of
that medium when not in use. We attain that purpose in general by releasing at
the proper time a weight, by the pressure or momentum respectively of which
cocks, levers or equivalent parts are moved, so that by these parts the gas,
electricity or other medium is turned off, as will be more fully described hereinafter.
In order to make our invention more clear, we refer to the accompanying
drawing, in which similar letters denote similar parts throughout the different
views, and in which :-
Fig. 1 shows a simple mode of execution of our device, the clock-work for
operating the click d being left away;
Fig. 2 shows an improved form, combined with a gas-meter,
Fig. 3 shows the working-parts of Fig. 2 in another position;
Fig. 4 shows a modification, to be used in connection with the arrangement of
Figs. 2 & 3.
Referring to Fig. 1, a is a rack connected with a weight b, and gearing with a
cog-wheel c on the shaft or plug of the gas-cock that is to be closed. Weight >>,
and with it rack a, are held in their upper position by a click d catching into a
suitable recess of said weight. This click is acted on by a suitable wheel-work
(not shown in Fig. 1) at the proper predetermined time, so that the parts b and a
are then released and cog-wheel c is turned, whereby the closure of the respective
gas-cock is effected.
We may also make use of the momentum of the weight when the latter is falling
a certain distance. We prefer to employ then the modification shown in Figs. 2 & 3,
in which said weight b is guided by a tube e, into which takes the click d. Fig. 2.
This click is operated by a pin f fixed to disk g; the latter is slowly rotated by the
clock-work h.
Rack a has a projection a¹ with an enlarged head a³, and is held by the mediation
of this head by a pair of pliers ii, which are secured to any suitable part. The
legs are grooved in their inner sides, as indicated by dotted lines, these grooves
forming an elongation of the space of guide-tube e. As soon as weight b is released
by click d, it falls down into the grooves, so that by the momentum of the weight,
and by the action of the latter on the sloping grounds of the grooves, the pliers are
opened, as shown in Fig. 3. Rack a is, thus, released by, and disconnected from,
the pliers, so that now by the weight of the rack cog-wheel c is turned, and the
rack opened.
Instead of employing a rack and a cog-wheel for turning the cock, we may also
use a lever k. Fig. 4. which takes through a suitable opening in the nart a

page_text: Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we
-claim is
°
1. As a checking-device for conduits, the combination with a weight & adapted
to be held in raised position by a click or equivalent part, of a second weight a
adapted to be acted on by said first weight when released, and to act in its turn on
the cock or cut-out of the conduit, substantially as described.
2. As a checking-device for conduits, the combination with a weight b adapted
to be held in raised position by a click or equivalent part, of a second weight a
held by a pair of pliers i, said.first weight when released, being adapted to open
the plier, and the second weight when released by the plier being adapted to turn
the cock or cut-out of the conduit, substantially as described.
