I WILLIAM BRIERLEY of number 72 Drake Street Rochdale in the County of
Lancaster Brass Founder do hereby declare the nature of my invention for
"AN IMPROVED INJECTOR FOR INSTANTANEOUSLY LIFTING AND FORCING LIQUIDS
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention consists of an improved arrangement or arrangements in injectors
for allowing the escape or free exit of steam thus aiding or assisting the water to
effect a passage uninterruptedly to its destination consisting of a valve to bo
operated by manual exorcise obviously the injector may be instantaneously started.
In order that my invention may be understood I refer to the accompanying sheet
of drawings Fig 1 is a vertical section of an injector shewing my improved
arrangements attached.
Fig. 2 is a vertical section of another modification of an injector with my
improved arrangements attached. It is well known that steam escapes from the
nozzle into the chamber A the mechanism of the nozzle being understood does not
require description in the drawings obviously prevents the passage of the water but
I provide a suitable valve B. which is opened for exit of steam into the chamber C
thence out as is well understood at the overflow or pipe D which valve it will bo
necessary to operate or open particularly when it is required to start or commence
the working of the injector it being manifestly evident that whon the superfluous
steam is extracted or allowed to pass out of the injector that a free and uninterupted
flow thro the passage. E. is the result.
Another modification of my arrangements is shewn in Fig. 2, the type of injector
being a non-lifting one water being admitted at the passage or inlet and the
steam at the passage or inlet G both combining and forming a jet to force the water
as is well known steam escapes into the chamber H. if an outlet were not provided
for the steam to escape the steam would obviously accumulate in the said chamber
consequently forming back pressure and thus obviate the passage of the water thro
the passage or nozzle. I to its destination the use of the valve B is for the purpose
of effecting a noiseless injector, the valvo B being opened affords a free passage to and
allowing any superfluous steam to pass out at the overflow or passage. J. the
opening and closing of the valve being effected by by operating the wheel K
attached to the spindle L having a suitable screwthread thereon. Having now

page_text: particularly described and ascertained the nature of my said invention and in
what manner the same is to be performed I declare that what I claim is,
First In an improved injector for instantaneously starting to lift and force liquids
the general construction and arrangement as herein fully set forth and substantially
as described and shewn in the annexed drawings hereunto.
Secondly. In an improved injector for instantaneously starting to lift and force
liquids the use and the application of the valve B. in combination with a chamber
or chambers substantially as and for the purposes herein fully set forth and fully
described in the annexed Drawings.
