PROVISIONAL SPECIFICATION.
An Improved Mixing and Suction Valve.
I, WILHELM FISCHER of Ludwigshafen-on-the-Rhine in the German Empire
Merchant, do hereby declare the nature of this invention to be as follows:-
The casing of the valve of this invention has two inlets and one outlet all of which
may be closed or regulated by means of a double seated valve comprising a valve-
plug or body capable of being operated so as to take on to or be moved away from a
fixed seating on the casing and a movable seating formed at the open bottom of a
hollow cylinder slide the interior of which is in communication with one of the inlet
orifices of the casing, both the valve plug or body and the hollow cylinder slide being
separately adjustable. By this construction the areas of the two inlets for the liquids
to be mixed or for the liquid or gas to be drawn or raised and steam or other gas
for effecting this purpose, and also the area of the outlet may be separately opened
shut and adjusted.

COMPLETE SPECIFICATION.
An Improved Mixing and Suction Valve.
1, WILHELM FISCHER of Ludwigshafen-on-the-Rhine in the German Empire,
Merchant, 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 invention relates to a mixing and suction valve in which the outlet passages
for the liquids or gases to be mixed may be set in any given relation to each other
consequently enabling the relative proportions of the fluids to be regulated.
In the accompanying drawing Figs. 1 and 2 are respectively a vertical section and
a horizontal section of the valve of this invention.
The valve has two inlets d S, e T, the passage through the former being closeable by
valve body c and seating o formed at the end of hollow cylinder slide 6 and through
the latter by the same valve body c and seating o¹ formed inside casing a.
Connected
to the valve body c is a rod h which higher up is carried by a screw thread in the
head of hollow cylinder slide 6 and in the guide or carrier m. The rod has fixed-
upon it a hand wheel k by which it may be turned round and thereby moved up and
down. The guide m engages between supports p fixed by their lower ends in the
valve casing and by their upper ends in a cross stay n with a central screw threaded
orifice in which works a screw spindle g through hand wheel 1 fixed upon it, upon
turning which the guide m and with it rod his worked up or down. If rod h is not
turned but only worked up or down from guide m the hollow slide 6 will accompany
it in its movement. If, on the contrary, rod h is turned, only the valve body c is
operated.
Supposing the valve to be closed and it is desired to admit liquid or gas by inlet e T,
then wheel is turned round moving rod g downwards and with it guide m, rod h
and hollow slide b which latter carries with valve body e so as to move it away from
its seating o¹. If it is desired to admit fluids by both inlets d S, and e T, then wheel k
is turned round moving rod / downwards whilst hollow slide 6 remains stationary. In
this way the valve body c is moved away from both seatings o, o¹.

page_text: Figs. 3 and 4 are views similar to the preceding, of a modified form of the
apparatus. The modification consists in that is a fixed part cast in one piece with
the valve casing, only the rod and valve body c being worked up and down.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A mixing and suction valve with two inlet passages and two tubular outlets, which
latter have a valve seating formed at the ends, closeable by a valve body common to
both, and either the one slideable within the other or both fixed, substantially as
described and shewn.
