We, PAUL BRENNICKE and THEODOR SCHILLER of Berlin in the Kingdom of
Prussia and German Empire, Engineers do hereby declare the nature of our
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
For the steam-motors used hitherto there is a boiler which forwards the steam
through pipes to the valve chest or cylinder for which it is intended. The steam
forced through these pipes does not keep up the tension it originally had on leaving
the boiler but a certain per centage of it is condensed, and a correspondingly greater
quantity of fuel is required to keep up a certain uniform power.
The accompanying drawing shews an atmospheric steam motor in which all
deficiencies produced by loss of steam are removed and an explosion rendered
impossible.
Fig. 1) shows a front view of the motor.
Fig. 2) shows a section through X Y.
Fig. 3) is a side view of the motor.
Fig. 4) is a section through U Z, in which the connection of the nozzle with the
valve-chest is conspicuous..
Fig. 5) is the opposite side view of the motor and shows the distribution of
steam.
Fig. 6) shows the valve-rod with the cam-disk.
"
7) shows the nozzle construction.
The water, which is sucked up out of a reservoir or tank by a pump, passes
through a so-called nozzle into a spiral-shaped serpentine-pipe which is situated
under the cylinder and which is kept in a heated state by a fire direct under it.
The steam passes on from there to the cylinder which has likewise become heated
by the heating gases. Steam is generated by small quantities of water being
constantly injected into the serpentine-pipe in which the water evaporates, and by
its continuously passing through the heated pipe the steam thus generated increases
in dryness and consequently in tension.
A indicates the pump by means of which the water is raised through the suction-
pipe S and connecting-pipe B and forced into the nozzle E. This nozzle, the separate
D

page_text: parts of which are shown in Fig. 7, is hollow, runs to a point at the end and is
provided with a screw-thread by means of which it is screwed into a particular
flange of the elbow-pipe D. This elbow-pipe has besides 2 other flanges. In the
middle of the screw-thread of the nozzle and at right angles to the cylinder part
of the nozzle, there is a hole a through which the water passes into the nozzle;
from the latter it is injected continuously into the serpentine-pipe in which it
evaporates.
The water thus converted into steam and constantly gaining in tension by the
heat of the serpentine pipe, leaves the latter (F) and passes into the valve-chest
and from there into the cylinder. The slide k is regulated in this case by the
valve-rod and the cam-disk, which latter is represented in Fig. 6. The fire-gases
which heat the serpentine-pipe afterwards pass round the cylinder situated above
the latter, through several chambers P1 P2 P3 and through openings R of the
partitions, which are alternately at the front or back of the latter, and when
their force is exhausted they escape through the chimney. When the steam has
performed the work it was intended for, it can be discharged through a valve v
(Fig. 5) which is in connection with the regulator, into the same tank it came from
originally in the shape of water. For the purpose of controlling the quantity of
water filled in there is a regulating-cock C in the pipe connecting the pump with
the nozzle and an indicator shows the degree or the quantity of water filled in
on a limbus. M is a clack valve placed within an air-vessel L which is attached
to the top of the pipe for the purpose of securing a uniform supply of water to the
nozzle, by regulating the pressure in the pipe.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
In a motor:
1) The application of a nozzle E in combination with a spiral-shaped serpentine
pipe F situated under the cylinder, water being constantly injected into the said
serpentine-pipe for the purpose of producing motive power, and the direct connection
of all parts named with the fire box, substantially as described.
2) The application of a clack valve M within an air-vessel L placed upon the
supply pipe for the purpose of regulating the pressure therein substantially as
described.
3) In a working cylinder, the casing P1 P2 P³ with alternating openings R. R.
for the purpose of heating it, substantially as described.
