Improvements in Cocks for Water-conduits.
I, ARNO RICHARD WAGNER, of 2 Kitscher Strasse, Crimmitschau, in the
Kingdom of Saxony, German Empire, 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 :-
My invention relates to cocks for water-conduits and has for its object to provide
means for protecting the pipes of the water-conduit from freezing in.
My invention will be more readily understood by reference to the accompanying
drawings, in which :
Fig. 1 is a sectional elevation of the cock with closed inlet-valve.
Fig. 2 is a side view of the cock with opened inlet-valve, partly in section.
Fig. 3 is a section of Fig. 1 on line a-b.
Fig. 4 is a transverse section of the cock.
Fig. 5 is a side elevation of a part of the cock.
Fig. 6 shows a section of a modification of the cock with the air-valve closed.
Fig. 7 shows a section of a modification of the cock with the air-valve opened.
A is the inlet-pipe, provided with the inlet-valve D preferably made of rubber,
B is the outlet-pipe and E the spindle, extending through the pipes A and B, and
bearing a cone F for opening and closing the air-valve C. The spindle E may
be moved by a spring J (Fig. 1 & 2) or by the turn of a screw H, as shown in
Fig. 5.
The air-valve C, as illustrated by Figs. 1, 2, 3 & 4, may be arranged as well at
the part A as at the part B, according as the cone F is mounted on the spindle E.
The pipe G serves for connecting the parts A and B and for the passage of the
water.
The operation of the described cock is as follows:
When the inlet-valve D is closed by the spindle E forming the connection
between the outlet part B and the valve D, the air-valve C is opened at the same
time by the cone F, as may be seen in Fig. 1. By the entrance of the air the
water contained in the pipe E and the outlet B, will completely flow out and is
thereby prevented from freezing in.
By opening the inlet-valve D, as shown in Fig. 2, the air-valve C is closed by
the backward movement of the cone F and does not admit the entrance of the air,
so that the water is not hindered to flow out by the exit B.
The air-valve C may be shut by the pressure of a spring S (Figs. 1 & 2) at the
drawing back of the cone F, or it is constructed as a ball-valve (Figs. 6 & 7). In
Fig. the inlet-valve D is closed and the ball-valve C admits the entrance of
the air by the opening K of the valve-chamber, whilst in the position, shown by
Fig. 7, the inlet-valve D is opened and the ball-valve C shuts the opening K by
the pressure of the water flowing through the opening L and pressing the ball of
the valve up to the opening K.
My improved cocks serve as outlet-cocks for water-conduits and are advan-
tageously distinguished from other constructions of this kind, because the inlet-
valve is located in the interior of the buildings, whilst the outlet may be out of
doors.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A cock for water-conduits, consisting of the combination with a spindle E,
moved by a spring J or the turn of a screw Hof an inlet valve D mounted on

page_text: said spindle and operated by the same, of an air-valve C, constructed as a spring-
valve or ball-valve and situated at the outlet-part of the cock, and of a cone or
equivalent part mounted on the spindle E and operating the air-valve C, for the
purpose as described.
Dated this 24th day of December 1892.
