Improved Device for Automatically Locking Cooks in the Closed
Position.
1, EMIL UBRIG, of Ahorn Allee II, Westend near Berlin, in the Empire of
Germany, Manufacturer, do hereby declare the nature of my said invention to be
as follows:-
This invention relates to a device for cocks, in particular gas-cocks, its object
being to automatically lock the plugs of cocks when in the closed position, and
thus wholly obviate the escape of gas arising from an improper or imperfect closing
of the cock.
With this improved cock, accidents and misfortunes such as gas-poisoning and
explosions, arising from the escape of gas from imperfectly closed cocks, cannot.
possibly occur.
It consists
The device is very simple and inexpensive, and can be fixed as well on new as
old or existing cocks without any essential alterations being necessary.
essentially of a spring, which, on turning the plug of the cock into the closed
position, either directly by means of a lever on the plug of the cock, or indirectly
by pressure against same, effects the complete closing of such plug, and locking of
same in this closed position in such manner, that the plug can only be opened by
overcoming the pressure of said spring.

Improved Device for Automatically Locking Cocks in the Closed”
Position.
1, EMIL UBRIG, of 11 Ahorn Allee, Westend near Berlin Manufacturer, do
hereby declare the nature of my said 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 use in connection with all kinds of cocks,
but especially gas-cocks, its object being-to effect an automatic and secure locking
of the plugs of cocks' when in the closed position; gas escapes arising from an
improper or imperfect closing of the cock, are thus wholly obviated, while accidents
and misfortunes, such as explosions, gas poisoning, etc. due to gas escaping from
improperly closed cocks, cannot possibly occur. Moreover the device is exceedingly
simple and may be attached to the taps or cocks' at present in use without any
material alterations being necessary.
Fig. 1 is a gas cock provided with the locking device and especially adapted for
use in streets, corridors etc.
the Jasion in the closed nosition:

page_text: Fig. 3 is a front view and
Figs. 4 and 5 side views of a gas cock provided with wire spring and shown in
the open and closed position respectively.
Fig. 6 is a modified construction of same.
In addition to the ordinary arm or lever a provided with counter-weight a¹ a
second lever b is connected to the lever a (Figs. 1 and 2). The free end of lever /
is hook-like and receives a spiral spring c, the other end of which latter is held
by the eye d of the part e of the fittings. On turning on the cock, the spring c
is put under tension and the lever b is moved so far past the vertical centre
that an accidental self-closing of the cock cannot take place (Fig. 1). It will
be seen that such closing cannot happen until the lever « has been raised so
as to carry the lever beyond the vertical centre, when the spring c under
tension brings the lever b into the closed position (Fig. 2) and securely locks
the cock.
The wire spring ƒ (Figs. 3, 4 and 5) for closing the cock and having two free
ends or arms¹, f, is secured to the cock by means of a screw or in any other
suitable manner. The arms, of spring fact on a cross piece i correspondingly
cut away in such manner that the tension of the spring on cross piece i effects the
secure automatic closing of the cock after same has been turned into the closed
position. The tension of the spring f for effecting this secure closing, is caused by
the plug being turned into the open position (Fig. 4) i.e. by the cross piece i forcing
the arms, of the spring f apart.
In the modification shown in Fig. 6 the spring f is arranged at the other end of
the plug of the cock beneath the nut . By means of such arrangement, the spring
is more easily attached to the cock and it may also serve for keeping the cock
tight.
If it be required, (in connection with the device shown in Figures 3-6), to
effect only a part closing of the cock, this may be readily done by correspondingly
cutting away the cross piece i so to form shoulders for the arms f, f of the
spring f.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Improved device for automatically locking cocks in the closed position, con-
sisting of a spiral spring (c) attached to the fittings of the cock and a lever (b)
respectively firmly secured to the plug of the cock, substantially as described and
shown in the drawing.
2. A device for automatically locking cocks, consisting of a spring (f) acting on
crosspiece (i) of the plug, which puts the spring under tension when the cock is
open, substantially as described and shown in the drawing.
