PROVISIONAL SPECIFICATION.
Improvements in Cocks or Taps.
We, ULYSSE ANDRÉ and OLIVIER DURAND of Barcelona, Spain, Engineers,
do hereby declare the nature of this invention to be as follows:-
With cocks or taps as at present constructed the plugs are liable to offer resist-
ance to the power applied thereto for opening or closing them, because of the
plug entering too far into the casing. This frequently necessitates striking upon
the lower portion of the plug, in order to diminish the amount of grip between
the plug and the casing.
Our invention has for object to provide a cock or tap in which such gripping
is impossible, and the extent of penetration of the plug in the casing is maintained
constant.
Fig. 1 shows by way of example a cock or tap according to this invention.
Figs. 2 and 3 are sections on the lines 1-2 and 3-4 respectively.
The plug a is screw threaded at a¹ to receive a nut e in the form of a ring which
is perforated with holes, of which there may be four, that allow of the operation
of the same by means of a skewer or pointed instrument.
The upper part of the plug casing is also screw-threaded at b¹ and receives a
nut a connected by connecting portions e' to a washer c' in such a manner as to form
a kind of abutment for the upper spring hereinafter referred to.
Two springs r and 1 of equal power, surround the plug, and are situated, the
former between the casing and the nut e, and the other between the nut e and the
washer c².
The parts of the nute which are in contact with the springs are bevelled to
facilitate sliding of the nut on the latter.
The putting together of the cock or tap is effected as follows:-
The plug a having first been placed in the position it is to occupy, the nut e is
located at equal distances from the casing and the washer forming the abutment,
this being readily effected by means of the nut e and washer c.
When this cock has been put together, the springs and being of equal power
will keep the nut e and consequently the plug in a constant position. This position
may readily be varied by means of the part c. It is obvious that if this part c be
screwed in one direction, the plug will be caused to move into the casing, and that
if it be screwed reversely the contrary effect will be produced.

COMPLETE SPECIFICATION.
Improvements in Cocks or Taps.
We, ULYSSE ANDRÉ and OLIVIER DURAND of Barcelona, Spain, Engineers,
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 —
With cocks or taps as at present constructed the plugs are liable to offer
5 resistance to the power applied thereto for opening or closing them, because of

upon the lower portion of the plug, in order to diminish the amount of friction
between the plug and the casing.
Our invention has for object to provide a cock or tap in which such gripping
is impossible, and the extent of penetration of the plug into the casing is main-
tained constant.
In the drawings left with our Provisional Specification
Fig. 1 is a central section shewing by way of example a cock or tap according
to this invention.
Figs. 2 and 3 are sections on the lines 1-2 and 3-4 respectively of Fig. 1.
The plug a is screw-threaded at a¹ to receive a nut e in the form of a ring which
is perforated with holes, of which there may be four, that permit of its being
turned by means of a pin wrench or pointed instrument.
The upper part of the plug casing bis also screw-threaded at
nut c connected by bars c' to a washer e in such a manner that
abutment for the upper spring hereinafter referred to.

Two springs, and of equal power, surround the plug stem, and are situated,
the former between the casing band the nut e, and the other between the nut e
and the washer 2. The parts of the nut e which are in contact with the springs
are bevelled to facilitate the sliding of the nut on the latter.
The putting together of the cock or tap is effected as follows:-
C
The plug a having first been placed in the position it is to occupy in the casing b,
with the springs r, surrounding its stem, the nut c with washer 2 is screwed onto
the casing at and the nut e on the plug stem is set at equal distances from the
screwed part of the casing and the washer c. When the cock has been thus
put together, the springs r and being of equal power, will keep the nut e and
consequently the plug in.a constant position in an end ways direction. This position
may readily be varied by adjusting the position of the nut for as will be obvious if
the nut e be screwed in one direction the plug will be caused to move into and fit
the casing more tightly, and if it be screwed in the reverse direction the contrary
effect will be produced.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A cock or tap provided with two springs arranged to act equally and in
opposite directions on the plug substantially as hereinbefore described for the
purpose specified.
2. The construction of a cock or tap substantially as described and shewn
according to which the plug stem is provided with two springs one of which is
arranged between the casing and an adjustable nut on the plugs stem whilst the
other is arranged between the said nut and a washer connected to another mut
screwed on the casing, the arrangement being such that when the plug is placed in
position it is to occupy in the plug casing endways movement of the plug will be
resisted by the action of the two springs.
