Specification Accepted, 26th Oct., 1888
I FRIEDRICH KRANICH Senior of Louisenstrasse 24, Darmstadt in the Empire of
Germany, Spur Maker 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 high pressure motors and reference being made to the
accompanying drawings.
Fig. 1 is a front elevation of the improved motor with cover plate and certain
interior parts removed. Fig. 2 is a front elevation with central part of cover removed
Fig. 3 is a cross section thereof. Figs. 4 to 9 are detail views on an enlarged scale
showing the chambers and passages or ports, the relative arrangement of which is
hereinafter described.
The improvement consists principally in so arranging a rotary body with certain
chambers or passages therein in combination with a stationary body having other
passages or ports that live steam or other motive fluid may in issuing from the passages
of the rotary body impinge or strike upon the sides of the passages or ports in the
stationary body or bodies and cause the rotary movement of the rotary body.
The invention also consists in certain features of construction and combination of
parts hereinafter described and claimed.
Within a suitable casing is journalled a rotary shaft W on which is keyed a wheel
or rotary body e having in its periphery a series of recessed chambers formed by a
series of walls or cross paddles integral with the wheel and two lateral wings g g
fastened against the same and having ports k inclined in direction as shown
in Fig. 4.
Around the periphery of the wheel e is the stationary ring e having entrance ports
in suitable number as shown in Fig. 1 communicating with the annular chamber 6¹
On each side of
in the casing to which live motive fluid is passed through pipe a.
the wheel e are the stationary annular plates 7 perforated by the exhaust passages k
corresponding to the passages & in the rings g g against which the rings 17 abut, but
inclined athwart the body of the plates in a direction contrary to the passages k so as
to form an angle thereto lying in the cylindrical plane of the wheel e or tangential
thereto.

page_text: The frame of the machine is suitably formed to permit the exhaust motive fluid
from the outlets e¹ of the passages k¹ to pass to the main outlet F. The motive fluid
entering the chambers in the periphery of the rotary wheel rotates the latter by
impact owing to the inclined position of the ports d and in issuing from the chambers
when the passages and k¹ coincide causes a further rotary force to be given to the
wheel by the angular change in the direction given to the issuing motive fluid by
the shape of the said passages.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is,
In rotary motors
1. The combination of a rotary wheel having in its periphery chambers, inclined
exhaust passages to said chambers, annular stationary bodies abutting against said
wheel and inclined passages in said bodies corresponding to and contrary in inclined
direction to said exhaust passages for the purpose set forth.
2. The combination of a rotary wheel having in its periphery, chambers adapted to
be fed with live motive fluid, lateral inclined exhaust passages to said chambers,
annular stationary bodies abutting laterally against the periphery of said wheel and
inclined passages in said bodies corresponding to and so inclined as to form with said
exhaust passages when in coincidence, angular passages lying in the plane of relative
direction of said passages for the purpose set forth.
3. The combination of a rotary wheel having on its periphery a series of angular
paddles, lateral flange plates secured to said wheel so as to form with said paddles a
series of chambers inclined exhaust passages in said plates, annular stationary walls,
abutting against said plates a series of passages in said walls adapted to form with
said exhaust passages when in coincidence, angular exhaust passages lying in the
cylindrical plane whose axis is the rotary axis of said wheel an annular stationary
ring enclosing the periphery of said wheel and live passages in said ring substantially
as set forth.
