A communication by HANS NICOLAI HANSEN-Goos, of Flensburg, in the
Province of Schleswig-Holstein and Kingdom of Prussia.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object an improved construction of valve which will
permit of an opening or closing being easily made in a space exposed to the full
pressure of steam, etcetera, and is therefore especially adapted for high pressures.
In carrying out the invention, the fluid pressure is balanced by subjecting two or
more equal areas to equal pressures in opposite directions. For this purpose the
cone is made hollow and the apertures for the entrance and the outlet of the steam
are placed one above the other and the steam enters both sides of the cone instead
of pressing against one side only. The pressure therefore coming from two
opposite sides will balance itself.
The steam or other fluid under pressure is conducted at its entrance as well as at
the outlet around the cock. Thus it is clear that the under aperture may be
employed for the inlet and the upper for the outlet or vice versa.

Improvements in Cocks or Valves.
A communication by HANS NICOLAI HANSEN-GOos, of Flensburg, in the
Province of Schleswig-Holstein and Kingdom of Prussia.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.1.M.E. of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster and 323, High Holborn in the
County of Middlesex, Civil Engineer, 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 :-
This cock or valve, which is intended especially to be employed where high
pressures exist, is furnished with a balanced plug, that is, one which is practically
free from pressure or at any rate one in which the pressures arising from the liquid
passing through are equally distributed. For this purpose, the plug is made
hollow and the liquid (as shown on the accompanying drawing) passes first from
the aperture of entrance through two channels o o half around the plug, which is
made hollow and then enters from both sides into the plug through apertures ff.
Two other apertures 9 g for the outlet of the liquid are placed under the
apertures ff, and the liquid on going out at both sides is also conducted around
the plug through the channels u u to the outlet i.
Thus the liquid is pressing against both sides of the plug instead of pressing
against one side only. The pressure coming from two opposite sides will balance
itself and thus the plug is balanced.

page_text: The liquid is conducted at its entrance as well as at the outlet round the plug,
thus it results that the under aperture. may also be employed for the inlet and the
upper for the outlet with the same effect.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
The improved cock or valve in which the liquid at the entrance as well as at the
outlet is conducted through two apertures of a plug placed opposite to each other
to avoid a pressure from one side.
