PROVISIONAL SPECIFICATION.
Improvements in Steam Traps.
I JAMES CONLONG of Hollin Bank Blackburn in the County of Lancashire Mechanic
do hereby declare the nature of this invention to be as follows:-
The object of this Invention is to more effectually remove the water from steam
pipes, and to improve the shape or form of said steam "traps" to more effectively
resist the pressure of steam.
In carrying out this Invention I form the box or trap of two oval iron dishes
flanged on the edges and bolt them together with bolts. The flanges forming a belt
round the box.
On the top part of the box 1 form a preparation for connecting a feed pipe, for
reciveing the water and steam from the pipes.
On the opposite side at or near the bottom of box I form a similar connection
for discharging the water on the top I fit an air valve to carry the air from the
pipes.
the arm.
In the internal arrangement I employ a ball float attached to an arm, formed with
an axis extending across the box, resting in a bearing formed in the box and working
freely on its axis. To the same arm or axis, I form a second arm at or near right
angles to the same. To this arm I fit a sliding weight with a set screw to fasten to
At a convienent distance from the axis on the arm extending to the ball
float, I connect a valve working freely on the arm of the double circular seating
type, but so constructed that the seatings are equal in diameter top and bottom. To
obtain this I form the valve face with a loose seating at the top and the valve spindle
with valve attached I form in two parts jointed between the valve wings or I form the
body of valve with an opening in the side to admit the bottom valve and joint the
valve spindle. In the valve the opening is closed when the valve has been fit and
ground in by a screwed plug and made steam and water tight.
The lever or arm carrying the aforesaid weight is set vertically and the arm
carrying the ball float horizontally or nearly so when in position for discharging
water.
The action of the trap is as follows on the steam and water entering the box by the
feed pipe the ball float rises in the box and lifts the valve which has been held down
by the weight of the ball float lever and weight lever (the weight lever arm and
weight being slightly over the centre) and allows the water to escape.
When the water sinks it is followed by the ball float and weighted lever bringing
the lever back over the centre and pressing down the valve shuts off the steam and
water, causing the valve to be full open to discharge water and fully closed down
when the water lowers in the box, and having equal seating in the valve, the pressures
are equal.

COMPLETE SPECIFICATION.
Improvements in Steam Traps.
1, JAMES CONLONG, of Hollin Bank, Blackburn, in the County of Lancashire,
Mechanic, 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 to more effectually remove the water from steam

page_text: pipes and to improve the shape or form of said steam traps to more effectively resist
the pressure of steam.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is partly a longitudinal section and partly a side elevation and Fig. 2 a
cross section of my improved steam trap complete, Fig. 3 is a longitudinal section on
an enlarged scale of the valve connected therewith.
In carrying out this invention and referring to the figures generally I form the
box of the steam trap of two oval iron dishes a, a' flanged on the edges and
secured together by means of bolts b, the flanges c forming a belt round the box.
On the top part a¹ of the box a, a¹, I form preferably on the side thereof, a
preparation or nozzle d, for the connection of a feed pipe which receives the con-
densed steam or water from the steam pipes. On the opposite side, at or near the
bottom of box a, a¹, I form a similar connection e for the discharge of the
condensed steam or water and on the top I fit an air valve f, to carry the air away
from the steam pipes or trap.
h
a,
In the interior of the box a, a¹ on the lower part a thereof, I employ a ball float
attached to an arm h, formed with an oscillating axis i extending across the box
and resting in bearings k, formed in the box a, a¹. On the said arm or preferably
on the axis i, I form a second arm l, at or near right angles to the same, which arm /
I provide with a sliding weight 1, made adjustable thereon by means of a set screw.
At a convenient distance from the axis i, I connect linklike to the arm / extending to
the ball float g, a valve m m³, see Fig. 3, of the double circular seating type, working
freely on the arm h, but so constructed that the seatings n, n¹ are equal in diameter
top and bottom. To obtain this, I form the valve casing p at the top with a loose or
removable seating n¹, and the valve spindle o with valves m m³, in two parts jointed
between the valve wing m² and the valve m; or I form the body or valve casing p
with an opening q in the side thereof to admit the bottom valve m which is afterwards
jointed to the valve spindle o. The said opening 9 is closed when the valve m m¹
has been fitted and ground in, by a screw plug g' made steam and water tight. In
order to prevent the valves m m being moved out of their true position by the float
arm h, I form the valve casing p with a stay or bridge p¹ through which the upper
end of the valve spindle o passes. The lever or arm carrying the aforesaid
weight is set vertically and the arm carrying the ball float g horizontally or nearly
so when in position for discharging the condensed steam or water from the trap. In
lieu of employing a ball float g as shown in the drawings a tile float may be used in
connection with the valve m, m¹ described.
The action of the trap is as follows, on the steam and water entering the box a, a'
at d through the feed pipe, the ball float g rises in the box a a¹ and lifts the valve m m¹
which has been held down by the weight of the ball float lever arm h and weighted
lever arm. The weighted lever arm and weight being slightly over the centre
it assists the movement of the same and thereby effects
in the direction of the float
an instantaneous opening of the valve m m¹ until the desired amount of condensed
steam or water has been discharged through the outlet e. When the water sinks in
the trap, it is followed by the float 9 and weighted lever arm 1 from the position
shown in dotted lines, to the position shown in full lines, thus bringing the weighted
lever over its centre of oscillation and pressing down and thereby closing the
valve m, m³.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is:
"In steam traps."
