We GEORGE GORDON PICKING and WILLIAM HOPKINS both of Bow Road in the
County of Middlesex Engineers do hereby declare the nature of this invention to be
as follows:-
This Invention relates to Improvements in Steam Dryers and water Ejectors, or
apparatus employed to automatically collect and discharge the water of condensation
from steam pipes, coils heaters pans and similar steam vessels or chambers, and has for
its object the more perfect collection of the fine particles of water contained in the
steam than in apparatus at present in use, also the automatic discharge of the water
thus collected.
The vessel according to this Invention is by preference made cylindrical and divided
by a perforated diaphragm in or about the middle. The steam and water enters on
one side of the upper part and is directed by an Internal pipe so that it dashes on the
perforated diaphragm or sides of vessel this deposits the water in the lower chamber
the upper half is also divided crossways so that the steain now comparatively free from
water passes through an opening in the top of the partition and is again directed by
another Internal pipe so that it again dashes on the perforated diaphragın or sides of
vessel this further frees the steam from the particles of water that might escape the
first pipe, and the steam then issues from the opposite side at or near the top of
the vessel dry and free from water of condensation.
The water collected in the lower vessel is automatically discharged by a float or
cistern working on a trunnion and draws a valve off the end of the discharge pipe
when the cistern sinks by reason of the water in the chamber having accumulated so
that it fills the cistern..
When the water from the inside of cistern is discharged out of the water pipe the
cistern or float rises and by so doing closes the valve or end of discharge pipe and
remains closed until sufficient water again accumulates to sink, it...

GEORGE GORDON PICKING and WILLIAM HOPKINS both of Bow Road in the County
of Middlesex Engineers, do hereby declare the nature of our said invention 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 improvements in stean dryers and water ejectors or
apparatus employed to automatically collect and discharge the water of condensation
from steam pipes coils, heaters, pans and similar steam vessels or chambers and has
for its object the more perfect collection of the fine particles of water contained in
the steam than in apparatus at present in use also the automatic discharge of the
water thus collected.
The vessel according to this invention is by preference made cylindrical and divided
by a perforated diaphragm in or about the middle. The steam and water enter on one
side of the upper part and is directed by an internal pipe so that it dashes on the
perforated diaphragm or sides of vessel this deposits the water in the lower chamber,
the upper half is also divided cross ways so that the steam now comparatively free
from water passes through an opening in the top of this partition and is again directed
by another internal pipe so that it again dashes on the perforated diaphragın or sides
of the vessel this further frees the steam from the particles of water that might escape
the first pipe and the steam then issues from the opposite side at or near the top of the
vessel dry and free from water of condensation.
The water collected in the lower vessel is automatically discharged by a float or
cistern working on a trunnion, and draws a valve off the end of the discharge pipe
when the cistern sinks, by reason of the water in the chamber having accumulated,
so that it fills the cistern, when the water from the inside of the cistern is discharged
out of the water pipe, the cistern or float rises and by so doing closes the valve or
end of the discharge pipe and remains closed until sufficient water again accumulates
to sink it.
And in order that our invention may be fully understood we shall now more
particularly describe the same and for that purpose shall refer to the Figures on the
annexed drawing the same letters or reference indicating corresponding parts in the
figures.
Figure 1. is a section of a steam dryer and water ejector constructed according to
this Invention.
Figure 2. is a plan of same in section.
Figure 3. is an external elevation.
Figure 4. shews a plan of same.
Referring to Figure 1, A is the outer box of the steam dryer, B is the cover bolted
on to same, C is the perforated plate, D is the float placed inside the outer box and
freely moving up or down working on the trunions E, which drop into recesses in
the sides of the outer box. The discharge pipe F is attached at the upper end to the
outer box A.

page_text: The cover B has two or more pipes G and H cast to same also a partition I.
The water and steam enters at J and passing through the holes K it is dashed against
the sides of the outer box A, the particles of water contained in the steam falling
through the perforated plate into the float or cistern D, the steam now partially freed
from its water rushes through the opening L down the pipe G and out at the opening M
it is again dashed against the sides of the outer box A and the remainder of the water
contained in the steam or such particles that might have escaped the first pipe are
thrown through the perforated plato into the float or cistern D below, the steam now
passes on perfectly free from water, the water dropping through the plate C and filling
the outer space N it runs over into the inside of the float D and causes it to sink this
uncovers or draws the valve off the end of the pipe F, the pressure of the steam then
acting on the surface of the water contained in the float D discharges the water up
the pipe F and from the outlot O, when sufficient water is blown out of the float D it
rises, and by so doing closes the valve on end of pipe F which remains closed until
sufficient water accumulates in the float to again sink it.
Having now described and particularly ascertained the nature of our said Inven-
tion and the manner in which the same is or may be performed we would observe
that what we consider to be novel and original and therefore claim as the invention
secured to us by the herein before in part recited Letters Patent is :-
Firstly. The arrangement and combination of parts constituting the improved
steam dryer and water ejector substantially as hereinbefore described and represented
in the accompanying drawings.
Secondly. The arrangement of a steam dryer with one or moro pipes to separate
the water from the steam as shewn and described.
Thirdly. The combination in one vessel of a steam dryer and a water ejector
worked by a float or any modification of same substantially as described.
Fourthly. In steam dryers and water ejectors the arrangement of an inner cistern
or float working on a fulcrum or trunnions substantially as herein before described.
Fifthly. In steam dryers and water ejectors in which the float works on a fulcrum
or trunnions the arrangement whereby the discharged pipe is brought near the
bottom of the outer box in the manner and for the purpose hereinbefore described.
Sixthly. In combination with the discharge pipe outer box and float as described
the use of the valve to close the end of the discharge pipe substantially as described.
