IMPROVEMENTS IN TAPS
Year: 1884

page_text: I, PROSPER AUGUSTE MAIGNEN, of 22 Great Tower Street in the City of London,
Filter Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN TAPS" to be as follows:-
My invention relates to taps which have to be fixed in orifices such as exist for
taps in Filters or other Vessels, and it is designed to afford a permanently secure
watertight and tasteless joint, thus obviating in these respects the drawbacks
attendant upon the use of Cork or india rubber as now practised.
My invention mainly consists of utilizing the reaction of a stop and a screw on
the through pipe of the tap, which leads through the orifice of the containing vessel,
to compress a packing of suitable material such as asbestos, in or around the orifice
in the containing vessel through which the pipe passes.
This may be effected in various ways with equally satisfactory results.
For example; The stop may be rigid with the through pipe and pressing on the
inner wall of the containing Vessel.--The through pipe is screw-threaded on the
outer end to receive the valve pipe, the rotative travel of which gives the necessary
pressure to produce the reaction of the stop and thereby to compress and expand a
packing of asbetos filled into the orifice of the containing vessel around the through
pipe.
Again, this may be modified or added to by forming the valve pipe with a flange
face abutting on a corresponding face formed around the orifice of the containing
vessel, the packing in this case being placed between the said faces, and compressed
by the reaction before specified.
Again, the stop, in place of being rigid with the through pipe, may be free to
travel upon the screw-thread, which, in this case, is formed at the same end of the
through pipe. The necessary resistance to rotation to permit the travel of the
screw, is produced by forming the stop with a projection, or of irregular shape, so
as to engage with the bottom of the containing chamber.-In this case the through
pipe and the valve pipe may be in one piece.
Again, the tightening up may be effected by an exterior nut, and the valve pipe
may be screwed on after the joint is made.-This will be suitable for convenience
in packing.

vessel.
I have specified instances of various modifications of my invention; but reserve
to myself the right of specifying further modifications (should I find such desirable)
in my complete Specification, so long as I do not depart from my main device, as
herein before indicated, of a reacting screw and stop on the through pipe of a tap,
to compress a suitable packing in or around the tap orifice.

page_text: COMPLETE SPECIFICATION.
I, PROSPER AUGUSTE MAIGNEN, late of 22 Great Tower Street, but now of
32 Saint Mary at Hill, both in the City of London, Filter Manufacturer, do hereby
declare the nature of my invention for "IMPROVEMENTS IN TAPS," and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
My invention relates to taps which have to be fixed in orifices such as exist for
the water exit in filters or other vessels, and it is designed to afford a permanently
secure and watertight joint, and thus obviate in these respects the drawbacks
attendant upon the use of cork, as now practised.
My invention mainly consists in utilizing the reaction of a stop and a screw on
the through pipe of the tap which leads through the orifice of the containing vessel,
to compress a packing of suitable material, such as asbestos or indiarubber, in or
around the orifice in the containing vessel through which the pipe passes. This
may be effected in various ways with equally satisfactory results, and in order
that my invention may be the better understood, I now proceed to illustrato
examples of the same in the accompanying sheet of drawings, in which like letters
refer to like parts throughout the figures.
Figure 1 represents one form of my tap. In this case the stop A is rigid with
the through pipe B, and presses on the inner wall of the containing vessel. The
through pipe B is screw threaded on the outer end to receive the valve pipe C, the
rotative travel of which gives the necessary pressure to produce the reaction of
the stop, and thereby to compress and expand a packing D filled into the orifice of
the containing vessel around the through pipe.
Again, (See Fig 2) this may be modified or added to by forming the valve pipe C
with a flange face E abutting on a corresponding face E', formed around the orifice
of the containing vessel, the packing D in this case being placed between the said
faces, and compressed by the reaction before specified.
Again, (See Figs. 3. 4 & 5) the stop A in place of being with a through pipe may
be free to travel on a screw thread F which is formed at the same end as the
through pipe. The necessary resistance to rotation to permit of the travel of the
screw is produced by forming the stop A with a projection, or of irregular shape, so
as to engage with the bottom of the containing chamber.
The through pipe and the valve pipe may be in one piece as shown in figures 3, 4,
and 5.
In the last named figure, the compressing nut and the flange of the tap are
formed with contrarily inclined faces, so as to press the packing D in a conical
form. Again, referring to figure 6, the tightening up may be effected by an exterior
nut G, and the valve pipe may be screwed on after the joint is made. This would
be suitable for convenience in packing.
The packing may be filled between the stop and the wall of the containing vessel
as shown in figures 4 and 6.
It will be seen that my device is capable of various modifications, of which I
have specified several examples, but it will be understood that I do not depart from

page_text: my invention so long as I employ my main device, as herein before indicated, of a
reacting screw and stop or nut on the through pipe of the tap, to compress a suitable
packing in or around the tap orifice.
Having now fully described and ascertained the nature and object of my invention
and the manner of its performance, I declare that what I claim is
1st The combination of a reacting screw and stop or nut on the through pipe of
a tap with suitable compressible packing in or around the tap orifice, substantially
as specified.
2nd The combination of a tap as first claimed with an opposing face and flange
between which the packing is compressed, substantially as specified.
3rd The construction of my tap in any of its modifications in one, two, or three
pieces, to suit circumstances, substantially as described.
