SEVERIN BORLAND, of the City of Manchester, in the County of Lancaster,
Engineer "IMPROVEMENTS IN OR APPLICABLE TO INJECTORS,"
Firstly, My invention relates to injectors, constructed without steam cone
spindles, and its object is to so arrange them that when when fixed several feet
above the surface of their water supply they will draw and lift it to start and
maintain the working of the injector, and my invention consists in dividing the
combining cone, or in using two combing cones with a space for overflow between
the first and second, in addition to the ordinary overflow, between the second
combining and the discharging cono
The fluid from both overflow orifices is or may be taken away from the same
branch or pipe.
Secondly My invention consists in combining the improvements described under
the first head of my invention with injectors described in the specification of
Letters Patent granted to myself N° 2499 A.D. 1880, by forming a short combining
cone so as to receive a second combining cone within a projecting casing from
the first.
This second cone has wings on its exterior that keep it central within the
projecting casing of the first combining cone and leave a passage, for the overflow
from between the first and second combining cones, that conducts it to join the
passage and outlet leading from the ordinary overflow orifice, between the second
combining and discharging cones.
Thirdly. My invention refers to an improved arrangement of injector with or
without the improvements under the first head of my invention, and it relates to
an improved combination and construction.
.
It consists of a casting having junctions for four pipes or connections one for
water, opposite to one for overflow, one for steam opposite to another for the
combining and discharging cones for the combined steam and water
The said casting has a diaphragm with a central orifice prepared to receive the
end of the combining cone or the end of the first combining cone which has
exterior wings the second part of the combining cone is also made with exterior
wings and to come in contact with the ends of those of the first combining cone.

page_text: The exterior wings of both cones fit into the interior of a casing or union which
also holds the end of the pipe attached to the end of the discharging cone and
these wings leave an annular passage leading to the branch in the said casting for
overflow.
By screwing the union on to the junction of the casting all the nozzles or cones
are properly held and securely jointed in their places, and by unscrewing the union
the combining cones or nozzles can be readily removed or replaced and the other
cones or nozzles inspected, and this is done without disturbing the pipe connections.
An ordinary steam cone or nozzle is used with the last described combination.
Fourthly. My invention relates to injector nozzles or cones combined with a
cistern for water supply and overflow, and consists of a cistern or box for water
a steam cone arranged in the casing of one side of the cistern a discharging cone
opposite to the steam cone in the casing of the opposite side of the cistern, with a
The water in
combining cone or cones between the steam and discharging cones.
the cistern or box surrounds the exteriors of the cones or nozzles and thus this
injector receives its supply of water directly from the cistern or box and the
overflow has also direct communication with the water in the interior of the box
or cistern which is kept supplied with water by means of a cock or equilibrium
or other valve, and ball or other float, floating on the surface of the water in the
cistern, which ball or float, will shut off or admit the water supply accordingly as
the level of the water in the cistern rises or falls above the level fixed upon.
In some cases, the combining and discharging cones are connected so as to be
moveable to and from the steam cone, to regulate the water supply, and in this
case, these adjustable cones are or may also be connected with the float, in the
cistern, by a lever, in such way that a fall in the level of the surface of the water
in the cistern, will move the combining cone nearer to the stream cone, and vice
versa when the water level of the cistern rises.
