PROVIDIUNAT OF
Improvements in Valves for Regulating the Discharge of the Water
of Condensation from Steam Traps.
I, WILLIAM BURLEY of 83 Pelton, Road, Greenwich in the County of Kent,
Millwright and Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in valves for regulating the discharge of
the water of.condensation from those steam-traps in which a ball or float lever is
employed for operating the discharge valve.
According to my invention the valve consists essentially of a cylindrically shaped
box or chamber communicating with the discharge outlet, and of a pair of rotary
Formed in
reciprocating discs working in conjunction with said box or chamber.
the box or chamber and in the discs are ports or openings which more or less
coincide when the water in the trap is discharged.
The ports or openings in the box or chamber may be at the end faces thereof
and the discs be carried by and move with an axis or spindle passing through the
box or chamber; the said axis or spindle being actuated by a ball or float lever
whose position is controlled by the rise and fall of the water level in the trap. By
this construction it will be seen that the end faces of the cylindrical box or
chamber would constitute valve seatings, and the discs, rotary valves working in
equilibrium thereon.
In order to facilitate the ready fitting together of the parts, one of the discs
may be formed in a piece with the axis or spindle, while the other may be made
detachable and be adapted to fit onto the opposite end of the said axis or spindle,
which is reduced in diameter at this part for its reception. The detachable disc
may be locked to the axis or spindle so as to turn therewith by a groove and
feather; and may be kept from shifting longitudinally thereon by nuts screwing
onto the end of the axis and pressing the disc tightly against a shoulder produced
by the reduction of the axis. The ball or float lever may be furnished with a
boss having a taper hole therein and adapted to fit onto a corresponding conical
portion formed on the opposite end of the axis or spindle, these parts being tightly
connected together by means of a uut or nuts.

COMPLETE SPECIFICATION.
Improvements in Valves for Regulating the Discharge of the Water
of Condensation from Steam Traps.
I, WILLIAM BURLEY of 83, Pelton Road, Greenwich, in the County of Kent,
Millwright and 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 :-
This invention relates to improvements in valves for regulating the discharge of
the water of condensation from those steam-traps in which a ball or float is
employed for operating the discharge valve.
According to my invention the valve consists essentially of a cylindrically shaped
box or chamber communicating with the discharge outlet, and of a pair of rotary

page_text: reciprocating discs working in conjunction with said box or chamber. Formed in
the box or chamber and in the discs are ports or openings which more or less
coincide when the water in the trap is discharged.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
Figure 1 is a longitudinal elevation ;
Figure 2 a horizontal section; and
Figure 3 a longitudinal vertical section of my improved valve.
Figure 4 is an elevation of the valve spindle shewn separately.
Figure 5 is a longitudinal section ;
Figure 6 a plan; and
Figure 7 a vertical cross-section taken on the line X X of Figure 5, shewing a
steam-trap with my valve applied thereto. The trap is of ordinary construction
and consists of a rectangular chamber A having an inlet at B through which the
steam and water of condensation enter, and an outlet at C through which the
water of condensation escapes. D is a tight fitting cover which is firmly bolted to
the rectangular chamber A and is provided with a valve E which closes when the
pressure within the trap rises above that of the atmosphere, during the entry of
steam, but opens when the pressure falls, so as to admit air to the trap and thus
destroy the vacuum which would otherwise exist after the condensation of the
steam. A lever handle E' may be pivotted to the cover in such a position as to
enable the valve E to be conveniently opened when it is desired to test the
working.
Referring more particularly to Figures 1 to 4 a is the cylindrically shaped box or
chamber formed with an internal cavity or space a' which communicates with the
water outlet. The end faces a² of this chamber constitute valve seatings or
surfaces upon which work the rotary discs or valves 16, said end faces being
provided with ports or openings as leading to the internal cavity or space a¹, and
the discs or valves with corresponding ports or openings 6. Passing centrally
through the chamber a is an axis or spindle 6 by which the said discs or valves are
carried and with which they move, the disc 1 being formed in a piece with the
spindle, while the disc is detachably connected thereto by the nuts 6. This
spindle has a shoulder at 65 against which the detachable disc bears, when the
nuts are tightened up, without unduly pressing upon the end faces a², the said
disc being locked to the spindle by a groove and feather or other suitable means so
that both the discs and the spindle move together. The opposite end of the
spindle is formed with a conical or taper portion 6 which is adapted to receive the
boss of the ball or float lever 6', said boss being provided with a taper or conical
hole, so that when the ball lever is in place on the valve spindle the parts can be
firmly connected together by tightening up the nut 68. This mode of connection
enables the angular position of the ball-lever relatively to the valve spindle to be
readily adjusted so that the discharge of the water can take place at the desired
water level.
It will thus be seen that as the water level within the trap rises the ball 6° will
actuate the ball-lever and so give a partial rotary movement to the spindle b,
thereby causing the ports or openings in the discs or valves to more or less
correspond with the ports or openings in the end faces of the cylindrical box a and
in this way put the contents of the trap into communication with the discharge
outlet. In Figure 5 the parts are supposed to be in about the position they
occupy when the discharge valve is just opening to allow the water to escape. It
will be seen that my valve is so constructed and arranged that it will under
ordinary circumstances always remain covered by the water in the trap.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved valve substantially as hereinbefore described consisting

page_text: essentially of a box or chamber having ports or openings therein communicating
with the discharge outlet and of a pair of rotary reciprocating discs likewise
having ports or openings therein and constituting equilibrium valves working over
the ports or openings in the said box or chamber though the intervention of a ball
or float-lever.
2. The improved construction of valve consisting of a box or chamber such as a,
and of a valve spindle such as 6 having a pair of discs or valves thereon one of
which is detachable said spindle also having a conical or taper portion near one of
its ends for the reception of the ball-lever substantially as hereinbefore described
with reference to Figures 1 to 4 of the annexed drawings.
3. My improvements in valves for regulating the discharge of the water of
condensation from steam traps substantially as hereinbefore described with
reference to the annexed drawings.
