Improvements in Anti priming Pipes for Steam Boilers, also
applicable to Separating Water from Steam in Steam Pipes
generally.
I GEORGE HENRY RICHMOND of
Derby Street Moss Side Manchester in the
County of Lancaster Mechanical Engineer do hereby declare the nature of this
invention to be as follows:-
The object of this invention is the construction of an apparatus which shall
prevent the escape of water with the steam from steam boilers and is also applicable
to the separating of the water of condensation formed in steam pipes from the
steam therein.
In carrying out my invention I form a horizontal casing provided with an inlet at
one end and at a distance up the inlet I provide a plate depending from the upper
surface of the casing to a slight distance beyond the inlet and at a further distance
beyond the plate I devide the casing into two compartments by means of a horizontal
plate and in the upper compartment thus formed I provide an outlet. On the under-
side of the lower compartment I form a pocket from which pocket I take a further
outlet such inlet and outlets may be provided with flanges sockets or other coupling
devices as desired. The application of this apparatus is as follows:-
When used as an anti-priming pipe the apparatus is placed within the boiler with
the outlet from the higher compartment fixed to the underside of the outlet block of
the boiler the whole apparatus being held in position by suitable brackets and the
outlet from the pocket in the lower compartment being put into communication with
the water in the boiler some distance below the water line by means of a pipe. It
will now be seen that upon the stop valve being opened steam and water will rush
through the inlet of the apparatus and come into contact with the plate depending
from the upper surface and will so be directed into the lower compartment from
which compartment the water will pass away into the pocket and through the pipe
into the water of the boiler and the steam will rise through the space formed between
the horizontal plate and the plate depending from the upper surface of the apparatus
into the higher compartment from which compartment it will issue through the
outlet thence through the stop valve and into the pipes in a perfectly dry state.
When the apparatus is used as a separator it is to be fixed as near the engine or
other machine to which the steam is being taken as possible with the inlet towards
the boiler and the outlet towards the engine or other machine such inlet and outlet
in this case being arranged upon the same centre line and upon the steam and water
of condensation coming to the apparatus the water will be caused to fall by reason of
the plates into the pocket from which it is to be discharged through a suitable steam
trap into the atmosphere and the steam will enter the engine or other machine in a
perfectly dry state. It will be obvious that when used as a separator the apparatus
may be fixed either horizontally or vertically and that as the lower compartment is
formed in the length of the apparatus thore is not much more room occupied by the
whole apparatus than there is by the flanges used to couple two lengths of pipe of the
same size together. This form of apparatus enables me to dispense with the long
vertical pocket hitherto in use which occupies much room and is so unsightly and
although I have only described one inlet it will be seen that when used as an anti-
priming pipe the apparatus may be provided with two inlets and two depending

page_text: plates so making the apparatus double ended which modification would enable the
apparatus to take up less head room in the boiler.

Improvements in Anti-priming Pipes for Steam Boilers, also
applicable to Separating Water from Steam in Steam Pipes
generally.
GEORGE HENRY RICHMOND of 5 Derby Street Moss Side Manchester in the
County of Lancaster Mechanical Engineer do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of this invention is the construction of an apparatus which shall
prevent the escape of water with the steam from steam boilers and is also applicable
to the separating of the water of condensation formed in steam pipes and apparatus
from the steam therein.
And in order that ny invention may be more readily understood and carried into
practical effect I have hereunto annexed a sheet of drawings illustrative of the same
which I will now proceed to explain with the assistance of the various figs. and
letters of reference marked thereon like letters being used in all views to denote like
parts.
Fig. 1 is a sectional elevation of my improved apparatus as applied for preventing
the escape of water from hoilers and
Fig. 2 is a sectional elevation of my improved apparatus as applied to steam pipes
or other apparatus for separating the water of condensation from the steam therein.
A is a casing provided with an inlet B at one end or as in the case of Fig. 1. at
both ends and at a distance up the inlet B I provide a plate C depending from the
upper surface of the casing A to a slight distance beyond the inlet and at a further
distance beyond the plate 1 devide the casing into two compartments by means of
a horizontal plate D and in the upper compartment E thus formed I provide an
outlet F. On the under-side of the lower compartment G in Fig. 21 form a
pocket H from which pocket H I take a further outlet J such inlets and outlets may
be provided with flanges K sockets or other coupling devices as desired.
The application of this apparatus is as follows:-
When used as an anti-priming pipe the apparatus is placed within the boiler
with the outlet F from the upper compartment E fixed to the underside of the
outlet block L of the boiler the whole apparatus being held in position by suitable
brackets and the outlet J from the lower compartment G heing put into communi-
cation with the water in the boiler some distance below the ordinary water level
by means of the pipe M. It will now be seen that upon the stop valve being opened
wet steam or steam and water will rush through the inlets B and come into contact
with the plates C depending from the upper surface and will so be directed into
the lower compartment G from which compartment G the water will pass away
through the pipe M into the water of the boiler and the steam will rise through
the space formed between the horizontal plate D and the plate C into the compart-
ment E from which compartment it will issue through the outlet F thence through
the stop valve into the pipes in a perfectly dry state.
When the apparatus is used as a separator it is to be fixed as near the engine
or other machine to which the steam is being taken as possible with the inlet B
towards the boiler and the outlet F towards the engine or other machine such
inlet and outlet in this case being arranged upon the same centre line and upon
the steam and water of condensation coming to the apparatus the water will be

page_text: caused to fall by reason of the plate C into the pocket H from which it is to be
discharged into the atmosphere. The steam trap which I find most suitable for
this purpose consists of the bottomless float O working in the tank N and actuating
the quick threaded screw valve P the air being discharged through the apparture
provided for the purpose the steam will now enter the engine or other machine
in a perfectly dry state. It will be obvious that when used as a separator the
apparatus may be fixed either horizontally or vertically and that as the lower
compartment is formed in the length of the apparatus there is not much more
room occupied by the whole apparatus than there is by the flanges used to couple
two lengths of the same size pipe together. This form of apparatus enables me
to dispense with the long vertical pocket hitherto in use which occupies much
room and is so unsightly.
Having now particularly described and ascertained the nature of my said inven-
tion together with the best methods with which I am acquainted for carrying the
same into practical effect I wish it to be understood that I do not confine myself
to the precise details relative proportions or dimensions of the various parts as the
same may be considerably varied without departing from the invention but what I
claim is
The combination of a casing with the plates C and D substantially as and for
the purposes hereinbefore described and illustrated on the accompanying drawing.
