PROVISIONAL SPECIFICATION.
Improvements in Injectors.
A communication from abroad by VALÈRE MABILLE, of Mariemont, Belgium,
Engineer:
I, SAMUEL SHEPPERSON DIXON, of 24 Queen Victoria Street, in the County
of Middlesex, Merchant, do hereby declare the nature of this invention, as com-
municated to me by my foreign correspondent, to be as follows:-
This invention relates to injectors for locomotive and other steam boilers: and,
as will be seen from the accompanying drawing, it has the advantage of being
extremely simple in its arrangement and construction, so that it may easily be
fitted up or taken to pieces for cleaning. This simplicity of arrangement and
construction also serves to render the injector much less liable to derangement
than is the case with injectors as usually constructed.
In the figure, which represents a longitudinal section of an injector made
according to this invention, A is the main piece and B the cock in same. C, D
and E are three internal cones. C is screwed into the rear end of A and D is
inserted from the forward end and abuts against the collar a. E is inserted
from the same end and is engaged by D as shown. F is a nose piece fitting on
the forward end of A.
Dated this 21st day of October 1890.

COMPLETE SPECIFICATION.
Improvements in Injectors.
A communication from abroad by VALÈRE MABILLE, of Mariemont, Belgium,
Engineer.
I, SAMUEL SHEPPERSON DIXON of 24 Queen Victoria Street, in the County
of Middlesex, Merchant do hereby declare the nature of this invention, as
communicated to me by my foreign correspondent, and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to injectors for locomotive and other steam boilers, and,
as will be seen from the accompanying drawing, it has the advantage of being
extremely simple in its arrangement and construction so that it may easily be
fitted up or taken to pieces for cleaning. This simplicity of arrangement and
construction also serves to render the injector much less liable to derangement
than is the case with injectors as usually constructed.
In order that this invention may be more readily understood I have annexed
hereunto two sheets of drawings illustrative of the said invention in which drawings
similar letters of reference indicate similar parts. In these drawings Figure 1
is a side elevation, Figure 2 an end clevation, with the attached waste-cock
hereafter to be mentioned shewn in vertical section, and Figure 3 a horizontal
section but with the waste-cock seen in plan. The said waste-cock is omitted in
Figure 1.
A is the main casting and B the cock or valve in the water branch or inlet X.
C is the steam cone and is screwed into the rear end of A. D is the combining
cone and is inserted from the forward end of A so that its flange d abuts upon

page_text: the annular ledge a.
The cone E is also inserted from the fore end of A and
engages D as shewn in Figure 3. F is the receiving or discharge cone screwing
into the discharge chamber end of the casting E as shewn. G is the wastecock.
The principle of action is as in other injectors of this type.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :—
The arrangement and combination of parts substantially as set forth.
S. S. DIXON.
