PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Raising Liquids.
I, MARK MACER, of Belgrave House, Enfield Highway, in the County of
Middlesex, Wheelwright, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to simplify the construction of pumps and water
lifters for raising liquids from a lower to a higher level.
Now according to this invention I take a tube of any suitable diameter and
material preferably galvanised wrought iron and to the bottom thereof I attach a
valve box containing a ball valve fitting a seating. Attached to or forming part
of the valve box is a suction rose or strainer to prevent the pump from becoming
choked by stones sticks and other substances.
Above the valve box and projecting into the tube is a steam pipe terminating"
in a trumpet mouthed or other suitably shaped nozzle which nozzle projects
upwards.
To start the pump it is only necessary to admit steam or other fluid under-
pressure to the nozzle.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Raising Liquids.
1, MARK MACER, of Bellgrave House, Enfield Highway, in the County of
Middlesex, Wheelwright, 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 object of this invention is to simplify the construction of pumps and water
litters for raising liquids from a lower to a higher level.
Now according to this invention I take a tube of any suitable diameter and
material preferably galvanised wrought iron and to the bottom thereof I attach a
valve box containing a ball valve fitting a seating. Attached to or forming part
of the valve box is a suction rose or strainer to prevent the pump from becoming
choked by stones sticks and other substances.
Above the valve box and projecting into the tube is a steam pipe terminating
in a trumpet mouthed or other suitable shaped nozzle which nozzle projects
upwards.
To start the pump it is only necessary to admit steam or other fluid under
pressure to the nozzle.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying drawings in which :-
Figure 1 represents section of an apparatus for raising liquids constructed
according to this invention.
Figure 2 represents a modified form of the same.
The same letters denote the same parts in both figures.
a is a tube of any suitable diameter and material but preferably of galvanised
wrought iron this tube forms the delivery pipe or rising main of the pump.
Attached to this tube by screwing or otherwise is a valve box 6 containing a

page_text: ball valve c fitting a seating d. The valve box and valve are preferably constructed
of gun-metal. Attached to or forming part of the valve box is a suction rose or
strainer to prevent the pump from becoming choked by stones sticks or other
substances.
Above the valve box b and projecting into the tube a is a steam pipe g termi-
nating in a vertical nozzle to direct the jet of steam or other fluid under pressure
upwards. I have found in practice that if the area of the pipe a is contracted
somewhat just above or on a level with the orifice of the nozzle the efficiency of
the apparatus is increased. This may be conveniently done by heating the pipe
and swaging or rolling the same to the required shape.
a
In the modified form of the apparatus shewn at Figure 2 the valve box has its
interior surface formed as shewn so as to contract the area above the orifice of the
nozzle and the seating for the valve c is formed in the suction rose f.
On admitting steam or other fluid under pressure to the pipe g the apparatus at
once commences to force the fluid contained in the well or tank up the rising main
or pipe a.
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 :-
1. In an apparatus for raising liquids the combination of a valve box having a
seating therein to receive a ball valve a delivery pipe attached thereto and a steam
pipe projecting into the said valve box above the valve and terminating in a
vertical nozzle all substantially as hereinbefore specified.
2. In an apparatus for raising liquids the combination of a steam pipe g
terminating in a vertical nozzle in a valve box b containing a ball valve c with a
pipe a having its area contracted above or on a level with the orifice of the said
nozzle substantially as herein before specified.
3. The modified form of the apparatus substantially as hereinbefore specified and
shewn at Figure 2 of the accompanying drawings.
Dated this 26th day of October 1893.
