I, ROGER PYE of 69 Darwen Street Blackburn in the County of Lancaster, Mill
Furnisher do hereby declare the nature of this invention to be as follows:-
In the construction of steam traps according to this my invention in order to ensure
a constant or frequent discharge of the water of condensation I employ a barrel or
pipe valve upon which is placed a semicircular or saddle valve, the latter being
attached by rod to a float, the ports in the pipe and saddle valves being opened and
closed by the rod through the action of the ball as the water accumulates in the trap,
and is discharged therefrom.
This form of valve obviates all difficulties through deposit on the seating of the
valves by reason of lime or other matter in the water.
The pipe and saddle valve are applicable to any kind of float, and in some cases the
float may be directly connected with the saddle valve, without the intervention of a
connecting rod.
The air valve consists of a rod on which is a loose mushroom beaded valve, the rod
extends across the steam trap or cylinder and is provided with screw adjustment
which may be on the rod or on the seating of the valve whereby the valve may be
adjusted or set to its true working position when first applied, and then it is secured
by lock nut.

Improvements in Steam Traps and in Air Valves thereof.
I, ROGER PYE of 69 Darwen Street Blackburn in the County of Lancaster, Mill
Furnisher, 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 :-
In the construction of steam traps according to this my invention in order to
ensure a constant or frequent discharge of the water of condensation I employ a barrel
or pipe valve upon which is placed a semicircular or saddle valve, the latter being
attached by rod to a float, the ports in the pipe and saddle valves being opened and
closed by the rod through the action of the ball as the water accumulates in the trap,
and is discharged therefrom.
This form of valve obviates all difficulties through deposit on the seating of the
valves by reason of lime or other matter in the water.
The pipe and saddle valve are applicable to any kind of float, and in some cases the
float may be directly connected with the saddle valve, without the intervention of a
connecting rod.
The air valve consists of a rod on which is a loose mushroom headed valve, the rod
extends across the steam trap or cylinder and is provided with screw adjustment
which may be on the rod or on the seating of the valve whereby the valve may be
adjusted or set to its true working position when first applied, and then it is secured
by lock nut.
Such being the nature and object of this my said invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this specification in which
Fig. 1 is a side elevation of my improved steam trap.
Fig. 2 is a like view in section.
Figs. 3 and 4 are views of parts detached and the several figures on sheet 3
illustrate details of the trap or parts detached.
According to this my invention I employ a hollow tubular or pipe valve 1 upon
which is placed and free to move thereon a semicircular or saddle valve 2 in part
spanning the tubular valve 1, the saddle being by rod 3, connected to a float 4, the
ports 5 and 6 in the pipe 1 and saddle valve 2 being opened and closed (see sheet 3) as
the float 4 rises or falls according to the level of water within the trap, that is to say,
when water accumulates, the float 4, will rise and through the rod 3 turn the saddle
valve 2 on its seating pipe 1 bringing the ports 5-6 over each other as shewn by
Fig. 2, and discharging the water whereon the ball and valve assume position shewn
at Fig. 3. Sheet 3.
The air valve consists of a rod 8 on which is a loose "mushroomn headed" valve 9.
The rod 8 extends across the cover or lid 7 of the trap and is provided at its other end

page_text: with a small hand wheel 10 and screw adjusting nut, so that the air valve may be
adjusted and then screwed by the said nut and when once adjusted requires no further
attention.
In first starting the trap the air valve 7 is open allowing the air to escape through
holes 8 84 but as the trap becomes heated the metal rod 8 expands carrying the
valve 9 to its seating 7A and so closes the apertures 84 84 and prevents the escape of
steam, at 11 is a "baffle" plate to prevent the sudden inrush of water disturbing the
float, and 12 is cleaning out plug.
This form of saddle valve 2 obviates all difficulties through deposit on the seating
of the valves by reason of lime or other matter in the water. The pipe 1 and valve 2,
may be used in combination with any form of float and in some cases the float may
be directly connected with the saddle valve, i.e. without the intervention of a
connecting rod such as 3. 13 is the inlet pipe.
The body or shell of the trap is made in two parts, the top portion 7 forming the
cover or lid, to examine the inside of the trap it is only necessary to withdraw the
bolts 14, 14, and remove the cover 7. the part 2 with float 4 can then be lifted out.
-
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. The hollow pipe 1 and the valve 2 in combination with a float such as 4
constructed as and for the purpose herein fully described.
2. The air valve consisting of expanding rod 8 and valve such as 9 in combination
with the seating 7A having aperture 8 as and for the purpose herein fully described.
3. The general construction, arrangement and combination of parts constituting
the improved apparatus herein fully described for purpose set forth and substantially
as illustrated by drawings annexed hereto.
