PROVISIONAL SPECIFICATION.
Improvement in Evaporating Devices for Cooling Gas- and Petroleum-
motors the Cylinders and Pistons of which are Rotating Round
a Stationary Črank.
I, OSCAR BRÜNLER, of Eutritzsch-Leipzig Braustrasse 15 in the Empire of
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:-
In order to cool the cylinders of gas- and petroleum-motors in cases in which the
cylinders rotate round a stationary crank, the arrangement illustrated on the
enclosed drawing is made.
This drawing represents a vertical section of a rotating machine provided with
this cooling-device.
The cylinders are at some distance surrounded with a cooling-jacket e of wire-
gauze which is as fine as not to let through water, but permits the latter to
evaporate.
The interspace closed up by the jacket e, is continued through the perforations d
which are opposed by the similar perforations d of the stationary crank-axle c.
The latter is hollow from these perforations up to pipe b which leads into the.
water-reservoir a. The interspace which is closed up by the jacket e is now filled
with water by means of the tap f, whereupon the cock g is opened. When
the motor is at work a strong evaporation takes place through the wire-gauze e,.
with which, as is known, a cooling of the cylinders goes hand in hand. The
evaporated water is replaced through fresh water being sucked from the vessel a
through pipe b.

Improvement in Evaporating Devices for Cooling Gas- and Petroleum-
motors the Cylinders and Pistons of which are Rotating Round
a Stationary Crank.
I, OSCAR BRÜNLER of Eutritzsch-Leipzig, Germany, 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 :-
In order to cool the cylinders of gas- and petroleum-motors in cases in which the
cylinders rotate round a stationary crank, the arrangement illustrated on the
enclosed drawing is made.
This drawing represents a vertical section of a rotating machine provided with
this cooling-device.
The cylinders are at some distance surrounded with a cooling-jacket e of wire-
gauze which is as fine as not to let through water, but permits the latter to
evaporate. The interspace closed up by the jacket e, is continued through the
perforations & which are opposed by the similar perforations d of the stationary
crank-axle c. The latter is hollow from these perforations up to pipe 6 which leads.
into the water-reservoir a.
The interspace which is closed up by the jacket e is now filled with water <by
means of the tapf, whereupon the cock g is opened. When the motor is at work
a strong evaporation takes place through the wire-gauze e with which, as is known,.

page_text: a cooling of the cylinders goes hand in hand. The evaporated water is replaced
through fresh water being sucked from the vessel a through pipe b.
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:
A cooling-arrangement for gas- and petroleum-motors the cylinders and pistons of
which are rotating round a stationary crank; consisting of the cylinder-jacket e
of close wire-gauze which is supplied with water through the pipe b, the hollow
shaft c, and the perforations d, at the rate at which the water is evaporated at the
surface of the gauze-jacket, through the quick rotation of the cylinders, as and for
the purpose set forth."
