PROVISIONAL SPECIFICATION.
Improvement in or connected with Screw-down Valves, Draw-off
Cocks, and other Valves or Taps.
I, WALDEMAR GOLLE, Manufacturer, of 94, Lothringerstrasse, Berlin, N.,
Germany do hereby declare the nature of this invention to be as follows:-
This invention relates to screw down valves, stop cocks, draw-off taps, closet
valves and other valves or taps which are subject to frequent use, and has for its
object, to facilitate the after adjustment, cleaning or repairs of such valves, by
avoiding the necessity of shutting the main valve controlling the pipe in which the
said draw-off cock is situated.
For this purpose I provide the valve casing with a stopcock situated between
the valve proper and the flange or screw joint which connects the valve casing to
the supply pipe or reservoir.
In the accompanying drawing
Fig. 1 represents a screw down valve packed with an indiarubber disc and
provided with an auxiliary stopcock according to my invention.
Fig. 2 represents a turncock provided with an auxiliary stopcock according to my
invention.
A is the valve casing, provided with an enlargement B adapted to serve as a
casing for the auxiliary valve, which for the sake of simplicity is an ordinary conical
plug C ground into the casing B. This plug may have a prismatic head and a
removeable key, or it may be provided with a handle or other suitable device for
opening and closing the plug.
If it is desired, to repair the draw-off cock or screw down valve, the liquid passage
leading to the said valve is first closed by means of the auxiliary cock, B, C; as
described.

COMPLETE SPECIFICATION.
Improvement in or connected with Screw-down Valves, Draw-off
Cocks, and other Valves or Taps.
I, WALDEMAR GOLLE, Manufacturer, of 94 Lothringerstrasse, Berlin N., 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 screw-down valves, stop-cocks, draw-off taps, closet
valves and other valves or taps which are subject to frequent use, and it has for its
object, to facilitate the after adjustment, cleaning and repairs of such valves, by
avoiding the necessity of emptying and shutting off the pipe in which the said valve
is situated.
Such an improvement is particularly useful in large buildings containing many
kitchens, workshops, gas engines, lavatories, hydraulic lifts or other appliances
which require a frequent and intermittent supply of water, and where it would be
inconvenient to shut off a considerable length of pipes, when it is necessary to
replace a packing disc in one of the delivery taps or valves.
For this purpose I provide the valve casing with a stopcock situated between the

page_text: valve proper and the flange or screw joint which connects the valve casing to the
supply pipe or reservoir.
In the drawing filed with the Provisional Specification
Fig. 1 represents by way of example a screw-down valve packed with an india-
rubber disc and provided with an auxiliary stopcock according to my invention.
Fig. 2 represents a turncock provided with an auxiliary stopcock according to
my invention.
The valve casing ▲ has on its inlet side an enlargement B adapted to serve as a
casing for the auxiliary valve, which, for the sake of simplicity, is an ordinary
conical plug C ground into the casing B. This plug may have a prismatic head
and a removeable key, or it may be provided with a handle or other suitable device
for opening and closing the valve.
If it is desired, to repair the draw-off cock or screw-down valve, (A) the liquid
passage leading to the said valve is first closed by means of the auxiliary cock C,
as described, after which the repairs may proceed, while there is pressure fluid in
the supply pipe.
In the same manner as the valves shown in the drawings, other kinds of valves
may be provided with an auxiliary tap, as the improvement is independent of the
special construction of the main valve.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
In screw-down valves, draw-off cocks, closet taps and other taps or valves, the
combination of the ordinary valve or valve-casing, with an auxiliary stop-cock for
the purpose of facilitating repairs, cleaning, and exchange of parts, substantially as
described.
