Middlesex do hereby declare the nature of this invention to be as follows:-
This invention has for its object improved methods of forcing air or other gases
for blowing church or other musical organs or for any other similar purpose in
which it is desirable to obtain a steady flow of compressed air or other gases
independent of the demand upon the quantity and when it is desired that the
portion of the machinery which compresses the air should work with as little noise
as possible the generating force being operated at any convenient distance in a
situation where noise is not objectionable.
The whole apparatus when applied to blowing an organ, consists of the ordinary
reservoir commonly attached to organs, and a feeder or feeders: these also being
similar to those usually employed worked by means of a rocking bar or otherwise.
The feeder or feeders are operated by means of a piston or pistons working within
a cylinder or cylinders driven by compressed air: the valve arrangement of the
cylinder may be of any ordinary or well known kind.
Connected with this air cylinder, are two air mains which may be carried to any
suitable distance to where the generating power may be placed in such a position
where noise is of no material moment and the connecting pipes if necessary may
be lead considerable distances. The power generating portion of the apparatus
consists of any means of obtaining motive power suitable to driving an air com-
pressor such air compressor drawing air from the exhaust side of the air cylinder
which operates the feeders and pumping it into the pressure main of the said
cylinder-thus producing a continuous circulation of air through the pressure and
exhaust pipes as required.
Attached to the pressure pipe, are branch pipes to the pressure and exhaust sides
of the valve boxes on the motor or motors and suitable valves, preferably 3 way
cocks when more than one notor is used are placed upon the pressure and exhaust
mains or on the branches which valves or cocks are regulated by the air reservoirs
in such a manner that, as theso rise or fall more or less air pressure is admitted to
the motors actuating the feeders.
In another arrangement single cocks or valves may be used one being placed on
either the supply or exhaust from each motor opened when the corresponding
reservoir begins to fall and closed when it is full, combined with a single valve on
the main pipe which is operated by the combined action of the reservoirs.
In connection with the air reservoir a suitable compressing chambor which may
be in the form of small bellows or a cylinder and piston hereinafter called the
"regulator" may be arranged.
This compressed air is led by means of a small pipe into the place where the
motive power is situated and is used for operating a bye-pass between the pressure
pipe and the exhaust pipe or for operating directly on the suction valves of the air
compressor in such manner as to keep them elevated and so prevent the compressor
from compressing air-the air cylinder will not then be supplied with air at
pressure, and will cease operating the feeders until such time as the reservoir falls
sufficiently to allow the air compressor to re-commence working.
The regulation of the power supplied to the air cylinder actuating the feeders
may be automatically obtained without the use of the third pipe by utilizing the
increased rossure in the circuit when the reservoir is full

page_text: For further regulation a bye-pass may be placed between the pressure and
exhaust air pipes in a convenient position to enable the organist or operator to
open the circuit and thus allow of the free circulation of air during intervals
when the organ is not required and thus reduce the consumption of gas or other
motive power and in addition for this purpose a regulating apparatus consisting
of a bellows arrangement or piston and cylinder connected with the air pressure
main or the reservoir may be placed in conjunction with the throttle valve of the
motive power engine by which its speed is reduced when no air pressure is
required.
Suitable escape or other valves may be placed in the pipes to allow of the
discharge of any water which may collect.

Improvements in Machinery for Forcing, Air or other Gases.
JOHN CHARLES RAYMOND OKES Engineer, The Limes, Brondesbury Park,
Middlesex WILLIAM TOM GOOLD, Engineer 18 The Hawthorns, Finchley,
Middlesex 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 has for its object improved methods of forcing air or other gases
for blowing church organs or other musical instruments or for any other similar
purpose in which it is desirable to have a steady flow of compressed air or other
gases, irrespective of the quantity required, and where it is desired that the position
of the machinery which compresses the air should work with as little noiso as
possible, the generating power being at a convenient distance and in a situation
where noise is not objectionable. The whole apparatus where applied to blowing
an organ consists of the ordinary reservoir commonly attached to organs and à
feeder or feeders these also being similar to those usually employed, worked by
means of a rocking bar or otherwise.
The feeder or feeders are operated by means of a piston or pistons worked
within a cylinder or cylinders driven by compressed air. The valve arrangement
of the cylinder may be of any ordinary or well known kind.
Connected with this air cylinder are two air mains which may be carried to any
buitable distance to where the generating power may be placed in such a position
where noise is of no material moment and the connecting pipes, if necessary, may
be lod to considerable distances. The power generating portion of the apparatus
consists of any means of obtaining motive power suitable to driving an air
bompressor such air compressor drawing air from the exhaust side of the air
cylinder which operates the feeders and pumping it into the pressure main of the
said cylinder, thus producing a continuous circulation of air through the pressure
and exhaust pipes as required. Attached to the pressure pipe are branch pipes to
the pressure and exhaust sides of the valve boxes on the motor or motors and
suitable valves, preferably three way cocks. Where more than one motor is used
they are placed upon the pressure and exhaust mains or on the branches, which
valvės or cocks are regulated by the air reservoirs in such a manner that as tho
reservoirs rise or fall less or more air pressure is admitted to the motors actuating
the feeders. It is obvious that this method of regulation of the air motors; placed
at a distance from the power generating engine, can' be carried out in several
manners, for instance single cocks or valves may be used, one being placed on either
the supply or exhaust from each motor and opened when the corresponding
reservoir begins to fall and closed when it is full, combined with a valve on the

page_text: main pipe which is operated by the combined action of the reservoirs-or another
plan can be used whereby, in connection with the air reservoir; a suitable-
compressing chamber which may be in the form of a small bellows or a cylinder
and piston called the regulator may be arranged. The compressed air is led from.
the main by means of a small pipe into the place whore the motivo power is.
situated and is used for operating a byepass between the pressure pipe-and the-
exhaust pipe or it may be placed directly on the air compressor or upon the suotion
valves of the air compressor in such a manner as to keep them elevated and so
prevent the compressor from compressing air-the motor cylinder will then not be-
supplied with air at a pressure and will cease to operate the feeders until such time-
as the reservoir falls sufficiently to allow the air compressor to resume work. In.
the five sheets similar letters refer to similar parts as follows :

mover is worked at a distance from the secondary motor by compressed air, the use
of a delivery and return air pipe together with regulating apparatus as described
and herein set forth.
