"
WILLIAM HART and GEORGE HART, of the City of Manchester, in the County of
Lancaster, Brassfounders and Finishers. IMPROVED APPARATUS FOR INJECTING
FLUIDS INTO STEAM BOILERS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE FOR
OTHER PURPOSES."
This Invention which is represented in the accompanying Sheet of Drawings has
for its object the regulating of the supply of water or other fluids to steam boilers
and other purposes, and consists in making the nozzle marked a moveable so as to
cut off or enlarge the supply as required. For this purpose the nozzle a is provided
at its upper part with an internal and external screw b, c, one communicating with
the steam inlet and the other with the water supply. Connected to the water
regulator there is a hand wheel d, which on being turned acts upon the nozzle a
through the screw c and nut c, and shuts off the water, or steam may be cut off by
the spindle, and so answer the same purpose, the advantage being a great saving of
expense in the cost of the apparatus, and, being enabled to cast the body all in one
piece, there is less liability to get out of order.
be
This Invention is also applicable for any purpose where water is required to
raised and forced, such for instance as steam fire engines or any other purposes
where water is required to be lifted and forced.

WILLIAM HART and GEORGE HART, of the City of Manchester, in the County of
Lancaster, Brassfounders and Finishers. "IMPROVED APPARATUS FOR INJECTING
FLUIDS INTO STEAM BOILERS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE FOR
OTHER PURPOSES."
This Invention has for its object the regulating the supply of water or other
fluids to steam boilers and for other purposes, and consists in making the nozzle of
the injector moveable, so as to cut off or enlarge the supply of steam or water as
required. For this purpose the moveable nozzle is provided at its upper part with
an internal and external screw, one being in communication with the steam inlet
and the other with the water supply. Connected to the steam and water regulators
there are hand wheels fixed by screws and nuts. When one of the hand wheels is
turned it acts upon the nozzle through the screw and nut, and shuts off the water,
and by turning the other hand wheel which turns the steam spindle the steam is
cut off, or both can be turned at one time and so answer the same purpose.
All the parts where steam or water enters the injector are chambered out, and
where the water leaves there is a screwed pap which can be raised or lowered, or
regulated to the pressure required.
This Invention will be clearly understood by referring to the accompanying
Drawing which is part section of the improved injector.
a represents the body or shell which is cast all in one piece; b, the steam inlet ;
c, the water inlet; d, the overflow, and e the passage to the boiler or other place in
which is screwed the regulating pap f
For regulating the supply of liquids or fluids to the steam boiler or other place
we make the nozzle g moveable, so as to cut off or enlarge the supply of steam or
water as required. The upper part of the nozzle g is provided with an internal
screw j and external screw k, the internal screw j being in communication with the
steam inlet by means of the screw on the steam spindle m which is turned by the
hand wheel n fixed on the steam spindle, so that by turning the hand wheel n in
one direction it enlarges the supply of steam or in the other cuts it off. The external
screw k is in communication with the nut p which is fixed to the hand wheel q,
so that when the wheel q is turned in one direction it raises the nozzle g, and when
it is turned in the other it is lowered and allows the water to flów or be cut off as
required; or both of the hand wheels can be turned together and so answer the
same purpose. When this injector is only required for forcing we dispense with
the steam spindle m, and only use the nozzle g, which can be made moveable or
stationary.
Having now described the nature and particulars of our said Invention and the
manner in which the same is to be performed, we desire it to be understood that we
claim the improved apparatus for injecting fluids into steam boilers, which improve-
'ments are also applicable for other purposes as herein described and shewn, or any
mere modification thereof.
In witness whereof, I, the said William Hart, have hereunto set my hand
and seal, this Tenth day of July, in the year of our Lord One thousand
Witness,
