I, EDWARD PETER WAGGONER, of No. 715 E. Fayotte Street, in the City of
Syracuse, County of Onondaga, and State of New York, United States of America,
Mechanical 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 certain new and useful improvements in return-steam-traps,
the function of which is to free steam-pipes from the water of condensation and to
return such water to the steam-boiler, and consists in certain novel combinations of
parts and in novel details of construction as hereinafter set forth.
Referring to the drawings,
Figure 1 represents a side elevation of my apparatus, a portion of the bulb of the
receiving-chamber being shown in section ;
Figure 2, a plan view of the same; and
Figure, 3 a section through the trunnions in the plane of the line 33 of Figure 1.
1 represents the receiving-obamber, which is preferably constructed with brunchos 2
and 8 suitably connected together. To the branch 2, at its onter end, is attached a
cap 4, that may be removed for the purpose of cleaning the receiving-chamber. The
branch 3 is pivoted to hollow trunnions 5 6, through which the water of condensation
enters and leaves the receiving-chamber. The said trunnions entor suitable stuffing-
boxes 78 and communicato with chambers 9 10, which are preferably cast integral
with the base of my improved trap and are severally directly connected with the
water-inlet-valve 11 and the water-outlet-valve 12. The chamber 9 is preferably
constructed larger than the chamber 10 and is provided with a partition 13, which
divides said chainber 9 into two compartments 9 and 14, the compartment. 9 boing
directly connected with the inlet-valve 11, and the compartiment 14 being directly
connected with tho steam-supply pipe 15, which is preferably cast integral with said
base. To the outside of the compartment 14, and proforably aligned with the axis of
the receiving-chamber, is suitably securod a hollow trunnion 16, which enters a
stuffing-box 17. A pipe 18, oscillating in unison with the receiving-chamber, is
provided at one end with an extension which is directly connected to the stuffing-box 17
and oscillates in alignment with the trunnions 5 6.
I usually provide the receiving-chamber with an exterior pipu 19, preferably, cast
integral therewith, and having one end connected to the pipe 18 and its opposite end
extended upwardly and connected to the top of the bulb of the receiving-chambor 1.
Within the bulb of the receiving-chamber and preferably cast integral therewith is a
deflector or spreader 20, the function of which is to distribute the live-steam within
the receiving-chamber and secure the better, evacuation thereof. At a suitable point
on the bulb of the receiving-chamber and pivotally attached thereto is a link 21,
which in turn is pivotally attached to a lever-arm 22, supported in a projection 23 of

page_text: the base of the trap. To one end of tho said lever is attached a weight 24, of
sufficient size to raise the receiving-chamber into its uppermost position, as shown in
dotted lines, Figure 1. The base of the trap is provided with a stop 25, upon which
the receiving-chamber rests when in its lowest position, or when filled with the water
of condensation. The steam-supply pipe 15 previously described is provided with
an exhaust-valve 26, having a valve-stem extension 27, which is operated by the
oscillation of the receiving-chamber. Said steain-supply pipo is also provided with
an inlet-valvo 28 which controls the passage of the live-steam from the boiler into
said pipe. This valve 28 is operated by an arm 29, which projects from the
receiving-chamber 1 and is provided with a pin moving in a slot in an extension
of the stem of the valve 28. Although the said slot is quite long, it is so arranged
that the oscillation of the receiving-chamber will only open and close the valve when
said receiving-chamber reaches its extremes of oscillation.
Having now described the various mechanical details of any invention, 1 will
explain its operation, referring to Figure 1. When the receiving-chamber and other
operative parts of the device are in the position shown, the said chamber is full of
the water of condensation and the live-steam is about to enter or is entering the
valve 28. As the steam enters through the steam-supply 15, it passes into the
compartment 14, then through the hollow trunnion 16, and the pipes 18 and 19,
into the upper portion of the bulb of the receiving-chamber. Said steam is there
distributed by the deflector 20, and the water of condensation in the receiving-
chamber is forced, or, by the balancing of the pressure, is allowed to flow through
the lower branch of the said chamber and the hollow trunnion 6 into the enlarged
chamber 10, and thence to the boiler through the outlet-valve 12. As tho receiving-
chamber begins to lighten itself by the ovacuation of the steam, the weight 24 at the
end of the lever-arm 22 begins to raise said receiving-chamber into its uppermost
position, as shown in dotted lines, and the arm 29 begins to close the live-steam-inlet
valve 28. As soon as the supply of the live-steam is shut off, the pressure of the
live-steam within the various parts of my improved trap opens the exhaust-valve 26
and permits the water from the returns to promptly enter the receiving-chamber 1.
The water entering the receiving-chamber compels the same to descend and thus close
the exhaust-valve 26 and open the inlet-valve 28, whereupon the live-steam is free
to again enter said receiving-chamber for permitting the discharge of the water
therefrom.
The principle upon which my improved trap works, is that the pressure in the
steam-heating system is sufficient to force the water of condensation through the
inlet-valve of the device and into the receiving-chamber, that the prossure in
the receiving-chamber is reduced by the exhaust-valve in order that said chamber
may descend by the weight of the water of condensation, and that the live-stoam
flowing into the receiving-chamber equalizes the pressure in the receiving-chamber
and the boiler and thereby allows the water of condensation to flow by gravity into
the boiler.
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. In a steam-trap, a suitably-supported receiving-chamber oscillating upon and
communicating with hollow trunnions and communicating with the water-inlet and
outlet, an exterior live-steam supply oscillating in unison with the said receiving-
chamber and connecting and communicating with an oscillating extension oscillating
in alignment with the said trunnions, but having no communication therewith,
substantially as and for the purpose described.
2. In a steam-trap, a receiving-chamber provided with a deflector for the distribution
of live-steam and oscillating upon hollow trunnions connecting with the water-inlet
and outlet, and an exterior steam-supply pipe oscillating in unison with said receiving-
chamber and not communicating with said trunnions, substantially as and for the
purpose specified.

page_text: 3. In a steam-trap, the combination of a receiving-chamber oscillating upon and
communicating with hollow trunnions, with a base provided with a suitable support
for said receiving-chamber, n steam-supply provided with a valve operated by the-
oscillation of said receiving-chamber, an exhaust-valve communicating with the steam-
supply, a chamber having two compartments, one communicating with the steam-
supply and one with the water-inlet, a water-outlet, said water-inlet-compartment and
water-outlet being in direct communication with said receiving-chamber, and an:
exterior oscillating pipe conveying live-steam to said receiving-chamber for evacuating:
the same, substantially as and for the purpose set forth.
