An Improved Process for Producing Steam or Vapour, and an
Improved Device for Using the Steam for Pumping Water or
other Liquids.
I, RICHARD FIEDLER, Managing Director of the Firm of Transportabler
Dampfentwickler Gesellschaft mit Beschrankter Haftung, of Berlin, Jagerstrasse
11, in the Empire of Germany, 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 an improved process for producing steam and an
improved device for using this steam for pumping water or other liquids.
In the annexed drawing Fig. 1 shows the steam producer in vertical section.
Fig. 2 is a perspective view of the device for lifting or pumping water.
This process for steam producing consists in utilizing a body of any form pre-
ferably a cylindrical metal block in which there has been accumulated a certain
quantity of heat, this block having been heated in an appropriate fire place,
kitchen stove, forge hearth blast furnace or the like up to a high temperature.
When such a block 6 (Fig. 1) is placed in a glowing state in a cylinder c which
by means of appropriate heat insulation is protected as far as possible against
radiation and is closed tightly, by means of a cover d, it gives a certain number
of calories, which can be used for producing steam and be easily transported for
use at any place.
When the steam production is to begin, one has only to admit water through
the cock h, so that the water comes into contact with the glowing block and is at
once transformed into steam. The steam produced in the cylinder escapes
through the pipe r, and is carried to the place of consumption by means of appro-
priate pipes.
In the present case the example of construction shown in Fig. 2 has been
chosen, in order to explain the before described process for steam producing in
connection with a device for pumping water. The steam producing apparatus !
is placed on approximately the same level as the water w which has to be pumped
into the upper receiver e.
By means of a hoses the steam producing apparatus is in connection with the
receiver, so that by opening the cock h water enters into the steam producer l,
and the steam production begins. The steam produced in the steam producer / is
naturally only under a tension, equal to the pressure of a water column of the
tubes, as by the production of an over pressure in the steam producing appa-
ratus the water would be pressed back into the tube s and the steam produc-
tion would be interrupted. The steam leaving the tube passes to a pulsometer ?
of known construction, which by means of the pipe s¹ sucks the water, and
delivers it through the rising pipe 2 into the same receiver e, from which the
feed water flows to the steam producing device.
It appears to be a paradox, that steam of a tension, which measured as a water
column, is hardly equal to the rising height, should be able, to attain not only

page_text: the same rising height by direct pressure, but even to surpass it and to give a
considerable effect.
This effect is nevertheless produced by two causes. The one cause is that a
part of the steam is condensed and the exterior atmosphere pressure pressing in
consequence of the vacuum produced overcomes a part of the rising height. The
other much more important cause is that as already previously mentioned, there
takes place an intermittent rise of the steam tension, which is considerably
higher than the pressure of the water column to be overcome. As soon as the
steam produced in the steam producing apparatus has pressed back the feed
water in the pipes and has thus lost some of its tension, the water enters again
with increased velocity into the steam producer and continues to do so, until its
vis viva is compensated by the now again increasing steam pressure, whereupon
the water is again pressed back and so on. During the period of increase of the
steam pressure in the steam producer the steam pressure gives increased pressure
on the water in the rising tube 2 which is already in upward movement, and
drives it into the receiver. In this apparatus there takes place the same process
as in the water raising device known under the name of hydraulic ram.
The importance of this invention lies in the means of working the water rais-
ing device by steam power without as with hitherto known steam generators
expensive outlay for steam boilers, furnaces, chimneys and the like.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. An improved process for producing steam or vapour whereby heat is accu-
mulated in appropriate bodies such as metal blocks and the like and water or
any other liquid is conducted to them for the purpose of producing vapour.
2. A form of construction of the invention described in Claim 1 for raising or
pumping water and other liquids after the manner of a hydraulic ram, whereby
in a steam generator by means of the vis viva of the feeding water there is pro-
duced an intermittent increasing and diminishing pressure, so that the same in
the period of the increase can raise the liquid to a greater height than that, from
which the feeding water comes.
