PROVISIONAL SPECIFICATION.
Improvements in or relating to Injectors.
I, JOHANN HEINRICH of 22 Breslauerstrasse Berlin, O. in the Empire of
Germany Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention relates to double injectors and to injectors having double jet
nozzles and the object of the invention is to provide for the simple and automatic
charging or setting in action of the two jets the one after the other, as required to
set the injector in action, by the means hereinafter described.
The passage by which the steam passes to the main jet opens in the conical wall
which forms the seat of the valve by which the said passage is closed, the passage
by which the steam passes to the subsidiary jet which is used to bring the injector
into action terminates below the valve aforesaid. The valve is double having an
outer conical sleeve sliding on an inner tubular part flanged outward at its inner
end and having lateral orifices communicating with the interior of the tube and
closed by the outer sleeve. When the valve is raised the spindle which is fixed to
the inner tube draws out this tube so that the steam passes into the inner tube by
the orifices now uncovered and sets the first injector in action or, where a double
jet is used in a single injector, sets the inner jet in action. When the injector is
charged a continued lifting of the valve spindle will cause the flange on the tube to
arrive against and lift the outer conical sleeve on the valve so that the steam will
now pass also to the main jet or, where a double jet is used with a single injector,
to the annular jet around the aforesaid inner or central jet.
In a double injector the counter tube into which the jet nozzle projects may be
fixed at its lower end by a bridge carrying in its centre a screw threaded pin in the
line of the axis of the counter tube. This pin passes through a hole in the casing
and is secured by a nut outside the casing, a washer or washers surrounding the
pin under the nut.
Dated this 29th day of October 1891.

The invention is illustrated in the annexed drawing,
Fig. 1 showing in section a double injector.
Fig. 2 a single injector with double nozzle.
Fig. 3 is a detail of Fig. 2.
The passage k by which the steam passes to the main jet opens in the conical
wall which forms the seat of the valve by which the said passage is closed, the
passage by which the steam passes to the subsidiary jet which is used to bring

double having an outer conical sleeve i sliding on an inner tubular part f flanged
outward at its inner end and having lateral orifices e communicating with the
interior of the tube and closed by the outer sleeve. When the valve is raised, the
spindle which is fixed to the inner tube f draws out this tube so that the steam
passes into the inner tube by the orifices e now uncovered and sets the first injector
in action Fig. 1, or where a double jet is used in a single injector (Fig. 2) sets the
inner jet in action. When the injector is charged, a continued lifting of the valve
spindle d will cause the flange on the tube f to arrive against and lift the outer
conical sleeve i on the valve so that the steam will now pass also to the main jet
(Fig. 1) or where a double jet is used with a single injector, to the annular jet
around the aforesaid inner or central jet (Fig. 2). In a double injector the counter
tube O into which the jet nozzle projects may be fixed at its lower end by
bridges carrying in its centre a screw threaded pin t in the line of the axis of the
counter tube. This pin passes through a hole in the casing and is secured by a
nut outside the casing, a washer or washers w_v surrounding the pin under the
nut u as shown in Figs. 1 and 3. The upper end of the tube O is flanged at r to
fit securely in a similar recess in the supporting casing.
a
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. A double injector or injector with double nozzle having passages arranged
with reference to the valve and valve seat in combination with the double valve as
described.
2. In a double injector the construction for fixing the counter tube O as set
