Improvements in and relating to Orchestrions and other Musical
Instruments.
I, JOHANN DANIEL PHILIPPs, of 9, Solmstrasse, Frankfurt a/M, Orchestrion
Builder, 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 present invention relates to a double relay for crchestrions and like instru-
ments and has for its object to provide a substitute for the spring-pressed
actuating device for reversing the valves.
The accompanying drawings illustrate the arrangement in vertical section.
E is the pipe which extends in the usual manner from the scale block. It
opens into the wind chest K which is however not a compressed air wind chest,
but an air suction wind chest. On the inner floor or bottom of this air suction
wind chest K there is arranged the small suction bellows A into which the
duct e opens.
From the duct e there branches off a duct which communicates
by means of the perforated brass slide X directly with the wind chest K. Into
the wind chest K there opens at any suitable points the suction pipe S, and the
passage M which leads to the small bellows L. The bellows L is situated below
the passage M in the case of percussion instruments, and above the passage M
in the case of orchestrions. The passage M has also an aperture h which leads
into the open air. The apertures and are closed or opened by means of the
valves I and H which are mounted on a rod G that is operated by the small
bellows A.
The mode of operation is the following:-
The wind chest K is maintained constantly in a condition of rarifaction by
means of the suction pipe S. If now the air hole which belongs to the pipe E in
the scale block C becomes uncovered, the air will enter through the pipe E into
the passage e, and the rarified air in the wind chest K will suck the bellows A
pward. By this means the valve II is closed so that the rarifaction of the air
n the wind chest K now keeps on acting through the pipe M and raises or
epresses the bellows. I accordingly which thereby throws in a well known
anner into operation the mechanism that serves to produce the desired sound
tone. But if on the contrary, the entrance of air through the pipe E be
nterrupted, the rarifaction of the air in the wind chest K will suck the air from
he passage and bellows A through the slide X and passage x, so that the
ellows A will sink and thereby close the valve I, and open the valve H, and the
ellows L will be caused by the air entering at h, to rise, or (if the bellows L
situated above) to fall.
Having now particularly described and ascertained the nature of my said
vention and in what manner the same is to be performed, I declare that what
claim is:
11
A reversing action for pneumatic double-relays characterized by the fact that
a suction wind chest K there is arranged a hollawa A

page_text: excess pressure of the atmospheric air when the pipe E is open to the outside,
and is depresed when the pipe E is closed to the outside, by reason of the fact
that the sucking action of the wind chest K empties the interior of the bellows A
through the slide X and the passages and e, whilst by the rising and falling
movements of this bellows A, the valves H and I are operated in such a manner
that the passage M and consequently the bellows L, enters alternately into com-
munication with the suction wind chest K and the atmospheric air.
