IMPROVEMENTS IN COCKS OR TAPS
Year: 1883

page_text: PROVISIONAL SPECIFICATION left by the said John Ohren at the Office
of the Commissioners of Patents on the 31st May 1883.
JOHN OHREN of Rio de Janeiro in the Empire of Brazil, Civil Engineer,
"IMPROVEMENTS IN COCKS OR TAPS
"
This invention has for its object the construction of cocks or taps for controlling
the supply of fluids, in such a manner as to adinit of the plug being easily removed
without the application of any tool, cleaned and replaced with great facility, and
without the necessity for screwing or unscrewing any part of it.
My improved tap consists of a taper shell or barrel having at convenient angles
thereto the ordinary inlet and outlet connecting pieces cast on it. The shell or
barrel has at its smallest end and at right angles to the axes of the barrel a small
lug cast or otherwise attached to it. The plug is made taper to fit the taper
interior of the shell and has the usual fluid passage through it. At its largest end
it may be fitted with a handle or lever, or may be formed square, or other shape,
to engage in a key, or other appliance for turning the same. The opposite or
small end of the plug projects beyond the shell or barrel, and coincident with the
extremity of the shell there is a circumferential indent cut in it. To the lug is
pivotted a sheet metal catch that takes into the indent in the plug and thus
retains it in its place. To remove the plug all that is necessary is to press one
extremity of the catch, when the plug will be released and can be withdrawn at
pleasure. The plug and its seat can then be cleaned, and on being reinserted in
the, barrel and the catch pressed down, it is again fit for use.
Taps or cocks formed in this way may be made of any suitable metal or material
and are adapted for most purposes where the removal of the plug with facility for
the sake of cleaning, or otherwise dealing with it and the adjacent parts, is
requisite.

This invention has for its object the construction of cocks or taps for controlling
the supply of fluids in such a manner as to admit of the plug being easily removed
without the application of any tool, cleaned and replaced with great facility and
without the necessity for screwing or unscrewing any part of it.
My improved tap consists of a taper shell or barrel having at convenient angles
thereto the ordinary inlet and outlet pieces cast on it. The shell or barrel has at
its smallest end and at right angles to the axis of the barrel a small lug cast or
otherwise attached to it. The plug is made taper to fit the taper interior of the
shell, and has the usual fluid passage in it. At its largest end it may be fitted
with a handle or lever, or may be formed square or other shape to engage in a key,
or other appliance for turning the same. The opposite or small end of the plug
projects beyond the shell or barrel, and coincident with the extremity of the
shell there is a circumferential indent cut in it. To the lug is pivotted a metal
catch that takes or springs into the indent in the plug, and thus retains it in its
place. To remove the plug all that is necessary is to press one extremity of the
catch when the plug will be released and can be withdrawn at pleasure. The
plug and its seat can then be cleaned, and on being reinserted in the barrel and
the catch pressed down, or home, it is again fit for use.
In order that the foregoing may be more easily understood drawings are attached
hereto of which the following is a description. In each of the views similar letters
refer to the same parts. Fig 1 is an elevation in which A is the "cone," B the
barrel, C, C, the plug, D the handle or lever, E the connecting piece to the service
and F the stop, while G is the catch pivotted to the lug H by the screwed pivot I,
and takes into the indent J of the plug C, shown more distinctly in Fig 2. In
Fig 1 the lug H is shown as cast on to both the barrel and the lower part of the
cone, or connecting piece, while in Fig 3, which is a view taken on the opposite
side of Fig 1 a slight modification of. the previous form is exhibited, the lug being
drawn as cast on to the connecting piece alone. Fig 4 is an elevation, the view
being at right angles to that of Fig 3.-Fig 5 shows the application of the invention
to an ordinary gas tap, and Fig 6 the application to a bib-cock.
Taps or cocks formed in this way may be made of any suitable metal or material,
and are adapted for most purposes where the removal of the plug with facility
for the sake of cleaning or otherwise dealing with it, and the adjacent parts is
requisite.
Having now described and particularly set forth the nature of this invention
and the manner in which the same is, or may be used, or carried into effect, I
would observe in conclusion that I do not confine or restrict myself to the precise
details or arrangements which I have described or referred to, as variations may
be made therefrom without deviating from the principles or main features of this
invention, but what I consider to be novel and original and therefore claim as
the invention secured to me by the hereinbefore in part recited Letters Patent
is,-
The construction of cocks and taps having an indent J cut in the plug O, which

page_text: 18 secured to the barrel by a catch G pivotted to a lug attached to the barrel or
lower part of the cone or connecting piece, or both, as herein described and
shown on the drawings.

In witness whereof I the said John Ohren have hereunto set my hand
and seal this twentysixth day of November in the year of our Lord
One thousand eight hundred and eighty three.
