Improvements in Cocks or Taps.
We, LAMBERT ENGELS, FRANÇOIS HUBERT ENGELS and CÉSAR FRANÇOIS
ENGELS, trading as Engels frères, Metal Founders, of 11 Rue Gantois, Lille
(Nord), in the Republic of France, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the construction of cocks or taps with
fluid-tight cap-joints, capable of being used on pipes or conduits for water, steam,
gas or other fluids.
In order that the said invention may be more readily understood, we have shown
our improvements in the accompanying drawing by way of example only.
In this drawing:
Figure 1 is a vertical longitudinal section, and
Figure 2 a vertical transverse section, showing a cock having our improvements
applied thereto,
Figure 3 shows the said cock half in plan, and half in longitudinal section on
the line 1-2, Figure 1, the cap being removed in the half-section.
Figure 4 is a vertical longitudinal section, showing the application of our
improvements to a cock of small dimensions.
Figure 5 shows the said cock half in plan, and half in horizontal section on the
line 3-4, Figure 4.
Like letters indicate corresponding parts throughout the drawing.
Our improved cock comprises the usual shell or seat a in which turns a plug b.
In our improved cock, however, both the seat and the plug are provided at their
upper part with an inclined surface, so as to form a kind of circular groove or
channel as shown in the drawing.
In this groove is placed a ring e, to form the joint, this ring being either of
anti-friction metal or other material answering the same purpose and suitable for
ensuring a tight joint.
The whole is covered by a cap or cover d provided with lugs, Figures 1, 2 and 3,
and secured by means of the bolts or studs e, by pins or in any other suitable
manner; this method of fastening is preferred for use with fairly large cocks; for
cocks of smaller dimensions, however, the cap d is screw-threaded internally and
screws onto the upper part of the shell or seating a, Figures 4 and 5.
The cap or cover d, when secured to the seat a of the cock, presses against the
ring c and tightens the joint so that the plug is retained in its seat; fluid-tightness
is thus ensured and no accident need be feared.
It is obvious that our improvements can be applied to cocks of all kinds and
dimensions.

(Nord), in the Republic of France, do hereby declare the nature of this invention
and in what mauner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in the construction of cocks or taps with
fluid-tight cap-joints, capable of being used on pipes or conduits for water, steam,
gas or other fluids.
In order that the said invention may be more readily understood, we have shown
our improvements in the drawing accompanying our Provisional Specification, but
by way of example only.
In this drawing:-
Figure 1 is a vertical longitudinal section, and
Figure 2 a vertical transverse section, showing a cock having our improvements
applied thereto,
Figure 3 shows the said cock half in plan, and half in horizontal section on the
line 1-2, Figure 1, the cap being removed in the half-section.
Figure 4 is a vertical longitudinal section, showing the application of our
improvements to a cock of small dimensions.
Figure 5 shows the said cock half in plan, and half in horizontal section on the
line 3-4, Figure 4.
Like letters indicate corresponding parts throughout the drawing.
Our improved cock comprises the usual shell or seat a in which turns a plug b.
In our improved cock, however, both the seat and the plug are provided at their
upper part with an inclined surface, so as to form a kind of circular groove or
channel as shown in the drawing.
In this groove is placed a ring c, to form the joint, this ring being either of
anti-friction metal or other material answering the same purpose and suitable for
ensuring a tight joint.
The whole is covered by a cap or cover d provided with lugs, Figures 1, 2 and 3,
and secured by means of the bolts or studs e, by pins, or in any other suitable
manner; this method of fastening is preferred for use with fairly large cocks; for
cocks of smaller dimensions however, the cap d is screw-threaded internally and
screws on to the upper part of the shell or seating a, Figures 4 and 5.
The cap or cover d, when secured to the seat a of the cock, presses against the
ring c and tightens the joint so that the plug is retained in its seat; fluid-tightness
is thus ensured and no accident need be feared.
It is obvious that our improvements can be applied to cocks or taps of all kinds
and dimensions.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The improved cock or tap having a fluid-tight joint for the cap or cover,
comprising a ring arranged in a circular groove formed by two inclined planes
situated in the upper part of the shell or seating and of the plug respectively, the
whole being covered by the cap or cover which presses upon the ring and is secured

page_text: to the shell or seating of the cock in any suitable manner, substantially as
berein before described with reference to the accompanying drawing, for the
purpose specified.
