I, STEN ERIC ERICSON, of 2B, Bryggaregatan, Stockholm, in the Kingdom of
Sweden, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:
This invention relates to valves or cocks for water or other fluid.
The common kind of valves or cocks suffer from the disadvantage that when
they have to be repacked or otherwise repaired, the water or other fluid has to
be turned off by means of some other valve nearer the source. For instance when
a water tap in the kitchen or other place in a house needs re-packing or other
repairs the water has to be turned off in the street or, at the best, where the
water pipe enters the house.
The object of this invention is a valve which may be repaired without the
water having to be shut off first by means of some other valve, and the invention
consists, briefly speaking, in providing, besides the ordinary valve, an auxiliary
valve in the same casing, either so arranged that it closes itself only when the
ordinary valve is wholly open or taken out for repairing or so arranged that it
may be independently operated.
In the accompanying drawings Figure 1 shows a vertical section of a valve
according to this invention; Fig. 2 is a horizontal. section of the same, and
Fig. 3 is a vertical section of a modified valve.
Referring to the drawings by letters (like letters referring to the same or
corresponding parts in the different figures) a represents a division wall (in a
globe-valve), which is provided with valve-seats on both sides; 61 and 62 are the
two corresponding valves of which 61 is the valve ordinarily used for the jetting
on and turning off the water and 6 the auxiliary valve. A nut d or the like is
screwed on to the lower side of the valve 6 and the length of the same is so
adjusted that it prevents the auxiliary valve 62 from engaging with its seat until
the ordinary valve b¹ is either screwed up as far as possible or removed from the
valve casing. The auxiliary valve 62 is, on the side opposite its seat, provided
with a stem f, which is surrounded by a spiral spring e, tending to close the
valve 6 so much that the pressure of the water acting in the same direction as
the spring is fairly brought to bear upon the valve so as to entirely close it when
the ordinary valve b¹ does not prevent the closing of the auxiliary valve. When
the ordinary valve 61 has been repaired, it is screwed into its place, whereby the
auxiliary valve will be forced back from its seat and be held away from it, until
the ordinary valve again needs repairing. The auxiliary valve, being only used
while the ordinary valve is being prepared, will, of course, last a very long time.
The ordinary valve b¹ may be provided with a catch, to prevent the valve from
being screwed out too much, except when it is to be repaired, in which case the
catch is removed.
The modification shown in Figure 3 consists in having the auxiliary valve,
preferably in the shape of a plug, placed below the ordinary valve 6¹, and inde-

I, STEN ERIC ERICSON, of Bryggaregatan 2B, Stockholm, Sweden, Mechanical
Engineer, do hereby declare the nature of this invention, and in what nanner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to valves or cocks for water or other fluid.
The common kind of valves or cocks suffer from the disadvantage that when
they have to be repacked or otherwise repaired, the water or other fluid has to be
turned off by means of some other valve nearer the source. For instance when
a water tap in the kitchen or other place in a house needs re-packing or other
repairs the water has to be turned off in the street or, at the best, where the water
Fipe enters the house.
The object of this invention is a valve which may be repaired without the water
having first to be shut off by means of some other valve, and the invention con-
sists, briefly speaking, in providing, besides the ordinary valve, an auxiliary
valve in the same casing, either so arranged that it closes itself only when the
ordinary valve is wholly open or taken out for repairing or so arranged that it
may be independently operated.
In the drawings left with the provisional specification Figure 1 shows a
vertical section of a valve according to this invention; Fig. 2 is a horizontal
section of the same, and Fig. 3 is a vertical section of a modfied valve.
or
Referrng to the drawings by letters (like letters referring to the same
corresponding parts in the different figures) a represents a division wall (in a
globe-valve), which is provided with valve-seats on both sides; 61 and 62 are the
two corresponding valves of which 61 is the valve ordinarily used for the letting
on and turning off the water and 62 the auxiliary valve. A nut d or the like is
screwed on to the lower side of the valve 61 and the length of the same is 80
adjusted that it prevents the auxiliary valve 62 from engaging with its seat until
the ordinary valve 61 is either screwed up as far as possible or removed from the
valve casing. The auxiliary valve 62 is, on the side opposite its seat, provided
with a stem f, which is surrounded by a spiral spring e, tending to close the
valve 6 so much that the pressure of the water acting in the same direction as
the spring is fairly brought to bear upon the valve so as to entirely close it when
the ordinary valve b² does not prevent the closing of the auxiliary valve. When
the ordinary valve 6 has been repaired, it is screwed into its place, whereby the
auxiliary valve will be forced back from its seat and be held away from it, until
the ordinary valve again needs repairing. The auxiliary valve, being only used
while the ordinary valve is being repaired, will, of course, last a very long time.
The ordinary valve b¹ may be provided with a catch, to prevent the valve from
being screwed out too much, except when it is to be repaired, in which case the
catch is removed.

page_text: The modification shown in Figure 3 consists in having the auxiliary valve,
preferably in the shape of a plug, placed below the ordinary valve b¹, and inde-
pendent thereof. In that case the auxiliary valve may be turned by a suitable
key; so that persons that are not allowed to draw off liquid may be prevented
therefrom by simply closing the auxiliary valve which shuts the fluid off before
it reaches the ordinary valve. This kind of valve is especially suitable for use
in wine casks or the like.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination with a valve, of an auxiliary valve which automatically
closes only when the ordinary valve is fully opened or removed, substantially as
and for the purpose set forth..
2. The combination with a cock or tap-valve, of an auxiliary valve adapted to
be independently operated, substantially as and for the purpose set forth.
3. The combination with a cock or tap-valve, of an auxiliary valve adapted to
be turned by a removable key, substantially as and for the purpose set forth.
