PROVISIONAL SPECIFICATION.
Improvements in Traps or Boxes for Condensed Steam or Water.
I, GEORGE FLETCHER, of Masson and Atlas Works, Litchurch, Derby, in the
County of Derby, Engineer, do hereby declare the nature of this invention
(partly communicated to me by Ernest Y. Connell, of Nevis, in the West Indies
Engineer and partly my own invention) to be as follows:-
This invention relates to improvements in traps or boxes for condensed steam
or water of the kind wherein a float is employed in connection with the water
discharge.
In boxes or traps of this type, when discharging, the steam and water rushing
into the box or trap impinge on one side of the float and tend to force it to one side
thus interfering with the efficient working of the trap.
Now it is the object of my invention to remedy this defect and to this end
I provide means whereby the inflowing steam and water are evenly distributed
round the box so that pressure is not exerted on one side only of the float.
In carrying out my invention I provide a chamber or recess running round the
inside of the said trap or box into which the steam and water inlet opens. The
recess is separated from the body of the box by a baffle or the like which leaves an
opening into the box around the whole extent of the recess.
By this arrangement it will be obvious that the steam and water flowing through
the inlet pass into and around the chamber or recess and escape into the body of
the trap through the opening left between the recess and the baffle so that they do
not strike the float at one point as hitherto but are evenly distributed round the
same.

COMPLETE SPECIFICATION.
Improvements in Traps or Boxes for Condensed Steam or Water.
I, GEORGE FLETCHER, of Masson and Atlas Works, Litchurch, Derby, in the
County of Derby, Engineer, do hereby declare the nature of this invention
(partly communicated to me by Ernest Y. Connell, of Nevis, in the West Indies,
Engineer and partly my own 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 traps or boxes for condensed steam
or water of the kind wherein a float is employed in connection with the water
discharge.
In boxes or traps of this type, the steam and water rushing into the box or trap
impinge on one side of the float and tend to force it to one side thus interfering
with the efficient working of the trap.

page_text: Now it is the object of my invention to remedy this defect and to this end
I provide means whereby the inflowing steam and water are evenly distributed
round the box so that pressure is not exerted on one side only of the float.
In carrying out my invention I provide a chamber or recess running round the
inside of the said trap or box into which the steam and water inlet opens. The
recess is separated from the body of the box by a baffle or the like which leaves
one or more openings into the box around the whole extent of the recess.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which :-
Figure 1 is a vertical section of a steam trap or box made according to my
invention; and,
Figure 2 is a horizontal section on the line 2-2 Figure 1.
a is the box or trap, 6 the steam and water inlet into the same and c the float
having arms or guides c¹, c' which slide on a hollow spindle d supported in the
cover a¹ of the steam trap in the ordinary manner and serving as the discharge or
outlet pipe for the condensed steam or water.
e is the chamber or recess running around the inside of the trap or box a and into
which the steam and water inlet b opens as clearly shewn in the figures.
fis the baffle which separates the recess e from the body of the box or trap a,
the said baffle fleaving an opening g into the box around the whole extent of the
recess e.
By this arrangement it will be obvious that the steam and water flowing through
the inlet 6 pass into and around the chamber or recess e and escape into the body
of the trap a through the opening g left between the recess e and the baffle f so
that they do not strike the float c at one point as hitherto but are evenly distributed
round the same.
It will be understood that the shape and general arrangement of the recess e and
baffle can be altered and modified if required without in any way departing from
the spirit of the invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In traps or boxes, for condensed steam or water, of the kind wherein a float
is employed, forming a chamber or recess around the inside of the trap, into which
recess the inlet for the steam and water opens and which itself opens into the body
of the trap, substantially as, and for the purpose, hereinbefore described.
2. The manufacture and use of the improved trap or box for condensed steam or
water herein before described and illustrated in the accompanying drawing.
