page_text: I JOHN JAMES ROYLE of 27 and 29 King Street West, Manchester, Mechanical
Engineer, do hereby declare the nature of my invention to be as follows:-
In the returning of water of condensation to Steam Boilers by what is known
as Return Steam traps a difficulty is experienced when the water of condensation
comes to the "drip" box at various pressures and the object of this invention is to
render it possible to return to the boiler the water coming at such various pressures
without interfering with each other and holding up the water in one or more of
the "
drips."
“
In carrying out my invention I reduce the pressure of the steam and water at
each of the drips to a common pressure by a suitable arrangement of Steam Trap,
preferably a trap of which the actuating mechanism is on the atmospheric or low
pressure side of the valve such as in the Steam Trap for which Letters Patent
No. 6231 were granted to me on the 30th day of December 1882 and known in the
market as Royle's Syphonia" Trap. It is a property of this type of trap that it
really acts as a reducing Valve and reduces the pressure to a point sufficient to
operate the mechanism of the trap. It will thus be seen that by having one of
such traps on each "drip" in front of the drip box, the condensed water could be
discharged into the said box at an uniform and common pressure although coming
from a series of drips having various pressures say 5, 15, 20 or any higher
pressure.
In carrying out my invention I combine a series of these traps or the essential
parts of them in one box or enclosed casing. In using the "Syphonia" trap
I employ the well known Valve and float and arrange a series of such valves and
floats each under an inverted bottomless vessel fixed to the side of the main casing
and either side by side or over each other. Such casing having a small hole through

The "drip" box and Return trap which I prefer to use with these my present
improvements is one described in an application for Letters Patent by myself
No. 10148 and dated the 27th of August 1885 but it is also applicable for use in
connection with other descriptions of Return Steam traps. It will be obvious that
this combination of traps really forms a multiple steam trap and as such may be
used as a compact arrangement of steam trap for draining more than one set of
steam apparatus. By carrying the outlet pipe of this multiple arrangement upwards
it may if desirable be converted into what is known as a lifting trap.

Steam Traps, Applicable also in the Construction of a
Multiple Steam Trap.
I JOHN JAMES ROYLE of 27 and 29 King Street West, Manchester, in the
County of Lancaster, Mechanical Engineer, do hereby declare the nature of my
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
In the returning of water of condensation to steam boilers by what is known
as Return Steam Traps, a difficulty is experienced when the water of condensation
comes to the "drip" box at various pressures and the object of this invention is
to render it possible to return to the Boiler the water coming at such various
pressures without interfering with each other and holding up the water in one or
more of the "drips."
In carrying out my invention I reduce the pressure of the steam and water at
each of the drips to a common pressure: by a suitable arrangement of steam trap
preferably a trap of which the actuating mechanism is on the atmospheric or low
pressure side of the valve such as in the Steam Trap for which Letters Patent
No. 6321 were granted to me on the 30th day of December 1882 and known in the
market as Royle's "Syphonia" Trap. It is a property of this type of trap that it
really acts as a reducing valve and reduces the pressure to a point sufficient to
operate the mechanism of the trap. It will thus be seen that by having one of
such traps on each " drip" in front of the drip box the condensed water could
be discharged into the said box at an uniform and common pressure although
coming from a series of drips having various pressures say 5, 10, 15, 20 lbs. or any
higher or lower pressure.
On the accompanying drawing Fig. 1. is an end sectional view, Fig. 2. a side
sectional view and Fig. 3. an end exterior view of a Multiple Steam Trap con-
structed according to my invention and designed to receive the drips from six
separate and distinct drip pipes. Figs. 4. and 5. are an end view and side sectional
view respectively (upon a larger scale) of one of the valves employed shewn
separately.
In carrying out my invention I combine a series of traps or the essential parts
of them in one box or enclosed casing A. In using the "Syphonia" trap I employ
the well known valve B. (see Figs. 4. and 5.) and float C. and arrange a series of
Buch valves B. (one for each drip pipe and connected thereto by the tail pieces B¹)
each with its float C. under an inverted bottomless vessel D. fixed to the side of the
main casing A. and arranged either side by side or over each other-Such bottomless
vessels D. having a small hole E through or near the top to allow the condensed
water from its own respective drip pipe to enter and raise the ball float C. and
ensure the necessary lifting action.
Now supposing the casing A. to be filled with water it will be obvious that the
floats C. will all rise to their highest position (as indicated by one of the floats in
Figa, 1. and 2.) and open the valves B. Any water of condensation coming would

page_text: thus flow freely out through each valve into the casing A. and away by the outlet F.
until steam arrives when it would be trapped under the bottomless vessels D. causing
the floats C. to fall (as indicated by the five other floats) and close the valves B.
The small holes E. however allow this trapped steam to escape slightly so giving the
floats C. a constant tendency to rise and re-open the valves B. and liberate any
condensed water which may have accumulated in the pipes. It will thus be seen
that as the closing of the valves B. is caused by the accumulation of steam under
the vessels D. they really act as so many Reducing Valves reducing the steam (and
water) as it issues from the valve B. to a pressure equal to a column of water
measured from the water line under each vessel D. up to the outlet pipe F. It is
therefore clear that the closing of these valves B. being determined by the accumu
lating steam under the vessels D. and irrespective of the pressure behind such
valves a series of such valves arranged as illustrated enable me to overcome the
difficulty before mentioned viz:-that of various pressures interfering with each
other as all the pressures are by this improved apparatus reduced to one common
pressure as before stated. The outlet F. thus discharges at an uniform but lower
pressure into the atmosphere.
The "drip" box and Return trap which I prefer to use with these my present
improvements is one described in an application for Letters Patent by myself
No. 10148 and dated August 27th 1885, but it is also applicable for use in con-
nection with other descriptions of Return Steam trup. It will be obvious that this
combination of trap really forms a multiple steam trap and as such may be used
as a compact arrangement of steam trap for draining more than one set of steam.

if desirable, be converted into what is known as a lifting trap.
it may,
Although I have described my Patent "Syphonia" Trap as being the simplest
and most suitable for the purpose of this combined Trap, yet I do not confine
myself to such as there are other arrangements known in the market which would
perform the work in a more or less similar manner and the combination of which
as aforesaid I should consider to be modifications of my invention.
Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that the essential
feature of my invention and what I desire to claim is :-
1st. The improvements in or applicable to what are known as Return Steam Traps
substantially as herein before described.
2nd. The reducing action by which a series of pipes conveying steam and water
at various pressures is reduced to a common pressure substantially as and for the
purposes herein before described.
•
3rd. The general arrangement of Steam Trap forming a Multiple Trap where
compactness is of importance substantially as and for the purposes hereinbefore
described.
