COMPLETE SPECIFICATION.
Improvements in Steam-atomizers.
I, BRUNO WILLIBALD EMIL GRIEP, of No. 37, Hammerbrook Street, in the
City of Hamburg, in the Empire of Germany, Railway Station-master's Assistant,.
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:
-
The present invention relates to improvements in steam-atomizers for diffusing
steam in spray or in the form of dew to render it more effective in wetting the
air of closed rooms in order to absorb the sensible dry heat of such rooms for
instance of railway cars, theatres and the like, and with this end in view my
invention consists in certain novel features of construction and combination of
parts, as will be hereinafter fully described with reference to the accompanying
drawing, in which:
Figure 1 is a vertical section through the improved steam-atomizer;
Figure 2 is a similar view showing a somewhat modified form of the said
steam-atomizer.
Like letters of reference indicate corresponding parts.
On the walls of the respective room or apartment to be cooled or wetted there
are arranged one or more tubes a communicating with a suitable source of steam,
for instance with the calorifers or pipes of a steam heating arrangement. The
free extremity of the steam tube a leads into a chamber d of a cup shaped
connecting piece d carrying a suitable steam outlet tube b covered by a cap or
cowl 6. Extending from the connecting piece d and contiguous to the steam
tube a there is another pipe r designed to carry off the condensed steam or water
of condensation formed in the connecting piece d and outlet tube 6 when steam is
allowed to pass through them. The outlet of steam may be regulated by means of
a suitable screw down valve f arranged in the wall of the connecting cup-piece d
and fitting with its conical or needle shaped stem f¹ into a corresponding seat
provided in the partition wall 3. By screwing the valve stem f¹ more or less into
its seat the passage of a determinate quantity of steam form the tube a into
the outlet tube 6 is permitted or such passage entirely cut off respectively.
The screw down valve acts not only as a stop valve but also as a sprayer or
atomizer, so that the steam escapes through the space left betwen the cowl and
outlet tube in an extremely fine atomized state for impregnating or saturating
the surrounding air with the required moisture, whilst the condensed steam is
permanently conveyed through the pipe r.
In some cases it may be desirable or expedient to arrange a separate con-
trolling or cut off valve for the steam supply tube in order to allow that only a
predetermined quantity of steam can pass into the outlet tube in case the
above mentioned screw down valve or atomizer is wholly opened by mischief
loving persons or has become loose in any way. This feature of my invention
may be carried into practice as shown in Figure 2 by arranging or providing in
the connecting piece or cup-shaped casting d between the steam supply tube a
and the steam outlet tube or the regulating valve or atomizer f respectively,

page_text: besides the chamber da further chamber in the walls of which
chambers a separate controlling valve f may be lodged so as to control or
cut off respectively the supply of steam into the said chamber d. This controlling
valve may be protected by any suitable means or in any suitable manner from
being actuated by unauthorized persons. A second delivery pipe r¹ for the
condensed steam may extend from the said intermediate chamber d. The steam
passing through the pipee a enters therefore first into the chamber d of the cup d
whence it escapes through an opening de provided in the partition do and regulated
with reference to its outlet area by adjusting the position of the controlling
valve f, into the chamber. The supply of steam from this latter chamber
into the outlet tube b may be regulated by means of the screw down valve f as
already explained above with reference to Figure 1.
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. A steam-atomizer comprising the casting (7) having a partition forming
two chambers, a steam supply pipe communicating with one of said chambers, a
steam outlet pipe extending from the other chamber having a covering cap, a
discharge pipe for water of condensation from said second chamber, and a valve
controlling the passage of steam-through an opening in said partition, sub-
stantially as and for the purpose set forth.
2. A steam-atomizer comprising a casting (d) having suitable partitions forming
three chambers, a steam supply pipe communicating with one of said chambers, a
steam outlet extending from the second chamber, discharge pipes for water of
condensation from said second and from the third chamber, a valve device
controlling the quantity of steam passing from the first to the third or inter-
mediate chamber, and screw down valve controlling the passage of steam from the
third into the second chamber, substantially as and for the purpose described.
