Improvements relating to the Interruption of Currents of
Compressed Air or other Gas.
I, AUGUST RIEDINGER of the Kommanditgesellschaft für Popp'sche Druck-
luftanlagen, August Riedinger & Co., of Augsburg, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide mechanism whereby a current of
compressed air or other gaseous fluid may be controlled, that is to say cut off or
reinstated without friction or with inappreciable friction.
A current so controlled is very suitable for the impulsion of regulating mechanism
and by the absence of friction in its own control allows of very great delicacy of
result.
The invention consists in passing the said current of air out of one nozzle into
another placed opposite thereto and in line therewith and adapted to receive it.
The interruption of the current is attained by bringing a solid screen or plate
between the nozzles so that the air current striking against the plate diverted
and prevented from entering the opposite nozzle, or the interruption may take place
by moving one of the nozzles so that it ceases to be in line with the other. When
a screen is used as aforesaid the nozzles may be stationary and the screen movable,
or the screen may be stationary and the pair of nozzles movable.

COMPLETE SPECIFICATION.
Improvements relating to the Interruption of Currents of
Compressed Air or other Gas.
I AUGUST RIEDINGER of the Kommanditgesellschaft für Popp'sche Druck-
luftanlagen August Riedinger & Co. of Augsburg in the Empire of Germany
Manufacturer 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 object of this invention is to provide mechanism whereby a current of
compressed air or other gaseous fluid may be controlled, that is to say cut off or
reinstated without friction or with inappreciable friction.
A current so controlled is very suitable for the impulsion of regulating mechanism
and by the absence of friction in its own control allows of very great delicacy of
result.
The invention consists in passing the said current of air out of one nozzle into
another placed opposite thereto and in line therewith and adapted to receive it.
The interruption of the current is attained by bringing a solid screen or plate
between the nozzles so that the air current striking against the plate is diverted
and prevented from entering the opposite nozzle or the interruption may take place
by moving one of the nozzles so that it ceases to be in line with the other. When
a screen is used as aforesaid the nozzles may be stationary and the screen movable,
or the screen may be stationary and the pair of nozzles movable.
In the accompanying drawings the twe nozzles A, B connected respectively to
pipes for supplying and forwarding the compressed air are shown as mounted
opposite to one another in a stationary frame in Figs. 1 and 2 the screen P being

page_text: movable, in Figs. 3 and 4 the screen is fixed while the nozzle frame is movable the
nozzles being then connected to flexible or jointed pipes, in Figs. 5 and 6 the
nozzles are shown without a screen, the one nozzle A being fixed and the other B
movable.
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
The method for controlling an air or fluid current consisting in passing. a current
of air or fluid from a nozzle into another nozzle opposite thereto and causing the
entrance of the said current into the receiving nozzle to cease by insertion of a
screen between the nozzles or by shifting one of the nozzles out of alignment with
the other substantially as set forth.
