Improvements in Injectors.
THOMAS WILLIAM MORROW Engineer Railway Hotel, Walker Gate via.
Newcastle-on-Tyne Northumberland do hereby declare the nature of this invention
to be as follows:-
The improvements I claim are simplicity of construction and substitution of a
core of water instead of a core of steam. The outer casing of injector is filled
with steam and by means of a cone valve regulated by handle or wheel can be
adjusted to suit any pressure of eteam, by opening the valve a rush of steam passes
through cone, causing the water to follow in proportion to velocity of steam.

Improvements in Injectors.
1 THOMAS WILLIAM MORROW of the Railway Hotel, Walker Gate via.
Newcastle-on-Tyne, Northumberland, England 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 :-
My invention is designed to provide a cheap and simple construction of steam
injector for feeding water into steam boilers, or other vessels.
But in order that my invention may be better understood I will now refer to the
accompanying sheet of drawings which are to be taken as part of this Specification
and read therewith.
Figure 1, illustrates an elevation and Figure 2, a sectional view of my
injector.
Similar letters of reference indicate similar or corresponding parts where they
occur in both views.
In the drawings (A) is a steam cylinder to which is connected a pipe (B) leading
from the boiler. In said cylinder (A) is arranged a conically shaped regulating
valve (C), provided with a seat (D); (E) is a water inlet tube and (F) is the
outlet. When the valve (C) is open a passage (G) is formed which allows the
steam to enter the tube (F).
Any suitable arrangement may be used to either open or close said valve (C),
such as clutch gear, or the inlet tube may be screw threaded and a hand-wheel
employed.
A stuffing box (H) is formed upon one end of the cylinder (A) for the purpose
of allowing the tube (E) to be freely adjusted without permitting the steam to
escape.
The use and action of my invention are as follow:-
Steam from the boiler is admitted to the cylinder (A) through the medium of the
pipe (B), the regulating valve (C) is then opened, and the steam rushes through
the passage (G) into the pipe (F), the result is that a strong suction is caused,
which draws the water from the inlet pipe (E) and forces it through the pipe (F)
into a steam boiler, or other vessel.

page_text: 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 steam injector consisting of the combination and arrangement of a cylinder (A),
the water inlet and outlet tubes (E) and (F) and the conically shaped regulating
valve (C) provided with a seat (D), substantially as and for the purposes herein
described and as illustrated in my drawings.
Dated the 13th day of June 1894.
