A communication froin F. SAURER & SONS, of Arbon, Switzerland.
I. ALFRED JULIUS BOULT, of 323 High Holborn, in the County of Middlesex, M.L.M.E.,
do hereby declare the nature of this invention to be as follows:-
The present invention relates to a pump by means of which the fluid to be pumped
can be discharged either in one or in several directions, and in which in the latter
case the quantity to be discharged can be varied or regulated. This object is attained
by employing two or more forcing valves in separate chambers and by the chamber
over the suction valve not being in direct communication with the chambers under
the forcing valves but by means of openings formed in the plunger or piston or pistons
which is adjustable round its longitudinal axis by which means the quantity of fluid fed to
and discharged through the different valves can be regulated.
The plunger or piston or pistons is preferably adjusted by means of a lever attached
thereto.
In case the pump is constructed with two discharge pipes and valves the plunger
or piston or pistons may be formed with three openings by means of which the fluid
can be fed to either one or both of the said discharge pipes and valves while also the
quantity thus discharged inay he regulated by the position of the plunger.
If more than two discharge pipes are used the plunger can be formed correspondingly
with more openings, the construction of the pump otherwise remaining the same.
The plunger may be actuated in any well known or desired manner and the pump
may be mounted in any desired position, horizontal, vertical, or inclined.

Improvements in Pumps.
A communication from F. SAURER & SONS, of Arbon, Switzerland.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex, M.I.M.E.
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 :-
The present invention relates to a pump by means of which the fluid to be pumped
can be discharged either in one or in several directions, and in which in the latter
case the quantity to be discharged can be varied or regulated, This object is attained
by employing two or more delivery valves in separate chambers and by the chamber
over the suction valve not being in direct communication with the chambers under
the delivery valves but by means of openings formed in the plunger or piston or
pistons which is adjustable round its longitudinal axis by which means the quantity
of fluid fed to and discharged through the different valves can be regulated.
In the annexed drawing:
Fig. 1 is a vertical section of a pump constructed according to the present invention
and Fig. 2 a partial cross section on the line m-n of fig. 1.
This pump is characterised.
1. by a plunger k, being movable around its axis by means of a lever a.

page_text: chambers in which they are situated, are separated from each other and that the Buid
can be discharged in two directions if desired.
3, by the chamber above the suction valve d not communicating directly with the
chainbers below the delivery valves b, c, the plunger interrupting such
communication.
The plunger is perforated at the points p in such a manner that it can be adjusted
by the lever a so that its passages p may communicate with one or both delivery
valves and therefore the fluid to be discharged by the pump can be forwarded to
one delivery valve or to both according to the angular position of the plunger k.
The above described arrangement is the same if there are used more than two delivery
valves and in that case the number of the directions in which the fluid can be dis-
charged will be correspondingly increased. The operation of the plunger may be
effected in any known and desired manner both as regards its longitudinal as well
as its angular or rotary motion. The pump may be arranged vertically as illustrated
in the accompanying drawing, or it may be arranged horizontally or inclined at any
desired angle.
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 correspondents, I declare that what I claim is —
1. In a pump the combination with two or more delivery valves b c arranged in
separate chambers and one or more suction valves d arranged in another chamber
of a recessed or hollow plug such as working in the passage connecting the
delivery and suction valve chambers and so arranged that it may be turned on its
axis so as to deliver liquid in any desired and variable proportion as to the quantities
to one or more of the delivery valves or valve chambers substantially as herein
described and illustrated in the accompanying drawings.
2 In a pump a recessed or hollow plunger such as having one or more lateral
openings such as communicating with its interior said plunger being adapted to be
turned upon its axis substantially as described and illustrated in the accompanying
drawings.
3. The combination and arrangement of parts constituting the complete pump
substantially as herein described and illustrated in the accompanying drawings.
