IMPROVEMENTS IN STEAM TRAPS
Year: 1884

page_text: I ROGER PYE, of 69 Darwen Street, Blackburn, in the County of Lancaster, Mill
Furnisher, do hereby declare the nature of my said invention, for "IMPROVEMENTS
IN STEAM TRAPS" to be as follows:-
This invention consists, of an improved steam trap, of simple and inexpensive
construction.
According to this my invention, I employ a trap or closed vessel, having inlet
and outlet ways-Within the trap is a hollow float, (preferably of copper) provided
with a lid, and perforated at its higher or upper part, the float is connected to a
cap or socket pipe, which is received on the end of the outlet pipe, the end of
which terminates within the float, and is sealed-Ports or outlet passage ways, are
formed through the socket, and pipe referred to-The upper portion of the float
is perforated, so that when the water of condensation rises, to a certain height, the
end or upper part of the float, being against the lid, or a stop piece on the lid, of
the trap the water enters the float, through the perforations, until the float being
filled, or partially so, sinks, whereon its downward motion, turns the socket, until
its passage way, is over or linable with the passage way on the outlet pipe, and so
the water is discharged except sufficient for raising the float for purpose of closing
the outlet.
The use of a float, enclosing the outlet ports, protects the latter from sediment,
and obstructions.
There is an air valve as ñqual

I ROGER PYE of 69, Darwen Street, Blackburn, in the County of Lancaster, Mill
furnisher, do hereby declare the nature of my invention for IMPROVEMENTS IN
STEAM TRAPS" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention consists of an improved steam trap of simple and inexpensive
construction.
According to this my invention I employ a trap or closed vessel, having inlet
and outlet ways
Within the trap is a hollow float (preferably of copper) provided
with a lid, and perforated at its higher or upper part, the float is connected to a
cap or socket pipe, which is received on the end of the outlet pipe, the end of
which terminates within the float, and is sealed, Ports or outlet passage ways are
formed through the socket, and pipe referred to. The upper portion of the float
is perforated, so that when the water of condensation rises to a certain height,
the end or upper part of the float being against the lid, or a stop piece on the lid
of the trap, the water enters the float, through the perforations until the float
being filled, or partially so sinks, whereon its downward motion turns the socket
until its passage way, is over or linable with the passage way on the outlet pipe,
and so the water is discharged except sufficient for raising the float for purpose of
closing the outlet.
The use of a float enclosing the outlet ports protects the latter from sediment,
and obstructions-There is an air valve as usual.
Such being the nature and object of the 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 partily in section.
Fig. 2. is an end elevation of Fig 1.
Fig 3. is a detail.
At 1 is the casing of the trap-2. the inlet 3 a float mounted upon or connected
to the barrel 4. of the plug cock 5. so as to be lifted or elevated upwards by the
water of condensation until the upper part of the float comes in contact with
the stop piece 6 whereon the water enters the float by way of the perforations 7
and soon as the float looses its buoyancy it sinks to the bottom rest 8. The motion
of the float turns the barrel 4 until its port comes over or opposite the port in the
plug cock 5. and the water is discharged from the float by way of the exit 9. The
float will as the water accumulates in the casing 1. gradually rise, fill, descend and

page_text: discharge as above described. At 10 is a screw plug affording facility for cleaning
the trap. I do not claim the float per se what I do claim is
1. The general construction, combination, and arrangements of parts constituting
the improved steam trap herein described and illustrated by drawings.
2. The barrel, plug cock 4, 5. in combination with the float 3 as herein described
and illustrated.
