An Improved Mechanism for Preventing Freezing of Water Pipes.
We, ARNOLD NÜESCHI, of Flawyl, Veterinary, and ROBERT NÜESCHI, of Altstätten,
Mechanician, both in the Empire of Germany, 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:-
-
The present invention relates to a safety mechanism for preventing the freezing
of water pipes and has for its object a mechanism by means of which water
pipes of any kind may be closed or opened at desirable points, thus the stream
of the inflowing water can be closed at will and the water of the piping can flow
off whereby the danger of freezing of the water within these pipes is fully removed.
My invention will be fully understood with reference to the accompanying
drawing in which an example of the mechanism forming the subject matter of
my application is represented. The plug of the cock a is provided with an
angular boring f by means of which the water inlet pipe d as well as the water
outlet pipe e alternatively might be connected with the piping conducted upwards
into the different rooms of a dwelling. For sake of clearness I call this piping
house piping." A. cover c provided with an adjusting screw ? keeps the cock
in position such as to only allow a rotation in direction of its longitudinal axis.
The angular boring f of the plug of the cock is prolonged somewhat upwards by
means of a tube formed projection o. The house piping his connected to this
tube formed prolongation o by means of a socket s.
"
The house piping up to the lever arm is rigidly connected with the plug b
of the cock. In consequence hereof the house piping is rotated when the lever
arm t is rotated and owing to the existing connection the plug of the cock effects
a rotation corresponding to that of the lever arm.
In order to tighten the rotatable part of the house piping against the fixed part
of the same, a stuffing box, w, is arranged above the lever arm, the tightening
being effected by means of a packing i rigidly connected with the upper part of
the house piping.
The cock casing a may be provided with two or more apertures whereby it is
possible to conduct the liquid to one of the different openings by turning the
lever arm in a certain angle.
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:-
In a safety mechanism for preventing the freezing of water pipes, especially
house piping, the combination with a cock a, having a plug connected to the
lower part of the piping and provided with an angular boring, a lever arm t
fixed to the movable part of the house piping and adapted to rotate the plug b
in such a manner as to bring the angular boring in face of a second opening of
the cock casing whereby the inflowing water is stopped whilst the water within
the house piping flows off, substantially as described.
