A communication from abroad by EMIL HERMANN NACKE, of Kötitz, near Coswig,
Kingdom of Saxony, German Empire, Machine Maker.
I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, 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 :-
Steam traps or apparatus for discharging condensed water, working with an open
floating vessel or with a hollow float often fail in working, especially in the small
passages of the internal outlet valve, because of impurities choking or obstructing the
passage of the valve.
The object of this invention is to overcome this objection, and the invention consists
in providing steam traps or apparatus for discharging condensed water with a device,
whereby the internal outlet valve can be opened from the outside of the apparatus
without opening the latter or removing the steam pressure from it so that a
powerful steam-jet is caused to issue through the widely opened valve, and remove all
obstructions.
Figure 1 of the annexed drawings represents a steam trap or condensed water
discharge apparatus constructed according to this invention; is the internal outlet
valve and its seat; is a lever, on the longer arm of which the vessel hangs by
means of the rod s. k is a cylindrical spindle fitting easily within the cylindrical hole
of the valve seat n and carrying at its lower end the valve m. At its upper end the
spindle is threaded, so that by means of the nut ġ the valve m can be drawn tightly
against the valve seat n. If now a steam jet has to be driven through the outlet
valve vi, while the apparatus is under full steam pressure, the nut q is screwed by
means of its star-shaped arms into the position indicated in dotted lines and is then
forced down, so as to cause the spindle k to descend, until it meets the rod s. As
this rod is pressed down the lever h will lift the outlet valve v i. As soon as the
spindle is released from the pressure above, it will be automatically raised by the
steam pressure within the apparatus, until the valve m fits tightly on its seat.
If it is desired to allow steam to pass through the valve v, i for a certain period,
without being obliged to hold the spindle k in its lowered position by hand, the bent
arm is turned from its position, indicated in dotted lines, into the position in full lines,
so that it takes above one arm of the nut q and thereby prevents the steam pressure
driving the spindle k upward.
The opening of the valve v, i, can also be effected by a cam d, as illustrated in
Figures 2 and 3; by turning this cam by means of an arm w arranged outside the

page_text: apparatus, into the position indicated in dotted lines, the lever h is lowered and
consequently the valve vi opened.
The spindle k may be constructed as a screw spindle as illustrated in Figure 4, the
seat n being in this instance screw threaded internally. If the spindle k is turned,
the opening of the valve v, i, will easily be accomplished, oven against great internal
steam pressure and a great area of the valve m.
Mechanism such as is represented in Figures 1, 2, 3 and 4 can be applied to any
apparatus for discharging condensed water, whether working with an open floating
vessel or with a hollow float, in order to open the internal outlet valve from outside the
casing without removing the steam pressure.
In order to offer facilities for easily adjusting the valve cone in the line of its
axis after having removed the cover and for preventing any automatic displacement
by jerks or shocks after closing the cover and furthermore to prevent the point of
the valve cone slipping out of the opening or seat i in its movements, I provide the
following arrangements:
Above the tapering part of the valve its head is formed square or, if round, is
provided with two opposite plane sides. The upward prolongation of this head is
provided with an external thread, by means of which the valve v is screwed into a
nut, at the end of the lever h. The cover is provided with a projection o which
*comes near the head of v, there being a small intermediate space; the space between
the head of and the wall of the upright u is also very limited, so that if v
touches u or o, its point will never be outside of the opening i, therefore the valve in
being closed will always be guided into its seat.
Again the upright u (see Figure 5) is provided with two cheeks e which loosely
receive between them two sides of the head of v, so that v has only very limited play
for turning, as long as its head remains between the two cheeks e. The two latter are
prolonged sufficiently to form shoulders for the projection o of the cover, thus
preventing the projection o being brought into close proximity with the valve v and
jamming it against u, if the cover be closed.
If the cover is removed and the valve cone has to be adjusted in the line of its axis,
the pin c is withdrawn and the lever / with the valve v is raised a certain distance, as
indicated in Figure 5, until v is released from the cheeks e, e and can then be turned
at will.
It is obvious that with the cover removed any adjustments can easily be accomplished,
whereas, if the cover is closed any displacement by chance is prevented and the valve
cone v is unable to slip out of its seat.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, as communicated to me, I declare
that what I claim is
1. Constructing steam traps or apparatus for discharging condensed water with
mechanism whereby, without opening the casing of the trap or apparatus and without
removing the steam pressure, the internal outlet valve (which works otherwise only by
the automatic action of the trap or apparatus) can be opened at will from the outside,
so as to cause a steam jet to rush through the valve and to clean it from any impurities
which may have interfered with its proper working, substantially as hereinbefore
described.
2. The arrangement specified of a valve cone capable of being adjusted in the line
of its axis in combination with the projection o and the cheeks e, e, which, if the
cover is closed, prevent the valve cone from being displaced or unduly turned, as
set forth.
