Complete Specification Left. 24th Jan., 1890-Accepted, 1st Mar., 1889
PROVISIONAL SPECIFICATION.
Improvements in Injectors for Feeding Steam Boilers with
Water or other Liquids.
We THOMAS SANDIFORD of 32 Liley Street Rochdale Brass Founder and ALFRED
DIGGLE of 96 Mitchell Street Rochdale Brass Founder both in the County of
Lancashire do hereby declare the nature of this invention to be as follows:-
In a injector which is constructed with steam nozzle, combining nozzle, delievery
nozzle and one over flow chamber. In the centre of combining nozzle is an aperture
by which the steam passes freely in a diagonal line, so as to form a vacuum to lift the
water to injector delievering to one overflow chamber.
The aperture is covered by a concaved shell with space enough to allow steam and
water to escape the edge of which is made flat.
Directly opposite on the combining nozzle their is a loose disc or valve which will
close immediatly the momentum is formed to force the water into the boiler, thereby
stopping the water from flowing at overflow.

COMPLETE SPECIFICATION.
Improvements in Injectors for Feeding Steam Boilers with
Water or other Liquids.
We THOMAS SANDIFORD of 32 Liley Street Rochdale and ALFRED DIGGLE of
96 Mitchel Street Rochdale both in the County of Lancashire Brass Founders
Excelsior Brass Works Liley Street Rochdale 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 :-
"In an injector consisting of steam nozzle, combining nozzle, and delievery nozzle.
In the center of combining nozzle is an aperture by which the steam passes freely
in a diagonal line so as to form a partial vaccum, to lift the water to injector,
delievering same to one overflow chamber.
The aperture is covered by a concave shell with space enough to allow steam and
water to escape. The edge of which is made flat, directly opposite on the combining
nozzle their is a loose disc or valve, to cover the mouth of concave shell which is
closed by a spring immediately the momentum is formed, forcing the water through
delievery nozzle into boiler, such being the nature and object of the said invention we
will proceed to describe in detail the manner, in which the same is to be performed
and in order that the same may be clearly understood. we have sectional drawings
illustrated and have marked the same with letters for reference.
A is a steam cone by which the injector is worked A 1 and A 2 are nut and
union by which the steam nozzle is kept firm.
B is combining nozzle divided by an aperture which drawing shows closed by disc C
the spring D keeping same up to concave face edge. E is water side the steam
forcing down combining nozzle drawing the water and discharging same down
passages B1 between steam and combining cone then through the diagonal
passages E1 the disc or valve C. being opened by force of steam blowing through
steam cone A untill the momentum is formed to deliever water through delievery
nozzle F to boiler, when the disc will close by the action of spring D working loosely
on combining nozzle.

page_text: The nozzles A B F are all made fast being screwed in body of same G is the
overflow by which the steam and water escape from the aperture in combining
nozzle.
F is delievery nozzle through which the water passes to boiler.
Having now particularly described and ascertained the nature and object of our
Invention and in what manner the same is performed we declare that what we claim
is as follows
In an Injector having a sliding disc working to and fro on the combining nozzle
by means of the steam and spring as herein before described.
