Improvements in and in Means for Compressing Air for Signalling, or
for Operating Burglar or Fire Alarms or other indicators of a like
or similar kind, or for Forcing Purposes.
1, LOUIS MOREY, of 95, Battersea Rise, Clapham Junction, Loudon, S.W.,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in and in means for compressing
air for signalling or for operating burglar or fire alarms or other indicators of, a
like or similar kind or for forcing purposes.
The air compressor reservoir consists of a cylindrical body combined with which
are two valves, and a packed piston working in a cylinder or tube,-one valve
closing upon the stroke of the piston in one direction, and the other valve open-
ing to pass on the compressed air.
According to one construction the air compressor cylindrical body is dome-
ended and has open ends which will be screw tapped and plugged to form a union
with the leading pipes of supply or discharge as may be found requisite.
The air compressor body will be cast, and the open ends described will facilitate
or contribute to that production.
With the said cylinder body there are combined as part of the casting holding
down plates or lugs for securing the device in position and above the said body
are cast faces, flats or ears which serve as carriers or attachment means for bear-
ings for the air pump and driver device.
Following this construction the upper faces or bolting blocks will receive the
shoes or feet of bearings to carry a pump cylinder the piston whereof is worked
by a crank and transmission.
The end of the cylinder is connected through a valve or double valves (ball
valves for instance) so as to lead in air to the pump eylinder on the back stroke
of the piston but so arranged as to close the said valve or valves before the second
valve or valves opens or open upon the return stroke.
The said second valve or valves is or are connected by a drilled hole through
the cylinder body and connects or connect with the interior of the compressor
chamber.
The crank shaft is driven by gearing from a counter shaft and motion obtained
through a pulley and band or by a hand wheel or other means as the case may be.
The air tube or tubes leading to the signalling device is or are carried from the
compressor chamber through screw caps applied on or two seatings on the cylin
der body.
A corresponding fitting is provided for the application of a pressure gauge and
also where desirable for the application of a safety valve.
According to a modification of this invention the cylindrical body may be fitted
with capped ends instead of such being formed in the casting, that is, the body
made as an open ended cylinder or tube and the foot plate and end covers are made

page_text: with a flange to fit to the cylinder body and may be rivetted, or be screw threaded
and soldered or be otherwise attached to render the fitting air tight.
The air pump tube and the valves are fitted to the base plate and operate as
follows: The air inlet valve is fitted to its seating and communicates directly
outside with the air and when the piston is lifted the air is drawn in to the
cylinder but on the return stroke the said valve will close and the second valve
leading to the compressor cylinders will open by reason of the air forced out
therethrough from the piston cylinder into the compressor chamber.
The other cover of the cylinder is fitted with a central cap or cover to the open-
ing wherein the end of the piston cylinder is secured, and the piston rod passes
out through such cover and cap.
The piston rod so extending will be fitted with a handle or be linked to a crank
to give the requisite reciprocating motion.
On the top of this chamber is fixed in any suitable position the air valve, and
on the top of this valve is a weight which is connected to the main wire of the
signalling device or to be operated by a magnet, and this said valve weight is
held up thereby, so that upon the connections being operated by disturbing the
condition of quiescence of the signal or alarm, or if any place or thing has been
disturbed, the said valve weight will be released and will fall over on
the valve ΟΙ valve lever and thus operate to open the valve
and so allow the air to escape from the compressor chamber through the lead-pipe
to effect the signal or alarm.
The compressed air will be led away through a proper pipe attached to the
cylinder body or to the cap or cover of the said body.
This air compressor may be attached by the lead off pipes directly to any signal
or alarm or to a secondary reservoir connected with the signal or alarm.
Thus the compressed air communication from the compressor will be constant
after the charging takes place and whilst the signal or alarm remains in normal
condition; but, upon any disturbance of that condition, that is by opening a door,
window, sky light, strongroom, safe, cellar-cover or flap, or cabin on board ship,
or a railway train, or omnibus, or air pillow when a sleeper has to be aroused, or
otherwise any place the access to which is prohibited or restricted the signal com-
munication will be given and the tap or valve connected with the alarm will
become opened to permit of the escape of the compressed air through a whistle,
syren, or other sound emitter and such sound will be continued during the time
and until the attention of the authorised parties, attendant, watchman or officer
has been called.
Combined with this so actuated signal an electric circuit and electric light can
be employed which will be switched on thus indicating the location outside of the
premises or place and also the alarm signal can be given inside.
An electrical communication to operate an armature or to set free a spring,
or to release a weight to operate the compressed air tap or valve may in some cases
be employed if found desirable.
This compressor device may be employed for purposes of forcing, such as
inflating pneumatic tyres of vehicles, or for forcing through any system of pipes
a pressure of air to cleanse same, or to serve to remove obstruction therein.
Again it may be used as a blowing engine such as for organ blowing, or with
lighted gas as a blow pipe, or for forced draught, and many such like ways
where a maintained pressure of air may be useful or desirable.

page_text: Improvements in and in Means for Compressing Air for Signalling, or
for Operating Burglar or Fire Alarms or other Indicators of a like
or similar kind, or for Forcing Purposes.
I, LOUIS MOREY, of 95, Battersea Rise, Clapham Junction, London, S.W.,
Plumber, 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 certain new or improved means for compressing air
for signalling or for operating burglar or fire alarms or other indicators of a like
or similar kind or for forcing purposes.
In the accompanying drawings, Fig. 1 is a plan view of an air compressor
reservoir.
Fig. 2 a partial sectional longitudinal view of Fig. 1.
Fig. 3 is a central sectional view of a modification of the construction of air
compressor.
Referring to Figs. 1 and 2 the air compressor reservoir consists of a cylindrical
body a, combined with which are two valves b, c, and a packed piston d, working
in a cylinder e, one valve b, closing upon the stroke of the piston in one direction
and the other valve c, opening to pass on the compressed air to the reservoir.
According to one construction the air compressor cylindrical body, is dome
ended and has openings a¹ and ve², at the ends which will be screw tapped and
fitted with plugs to form unions for the leading pipes of discharge of compressed
air, and are to be fitted with regulating or reducing valves one or more as required
to regulate the discharge of the compressed air, and render it uniform at varying
internal pressures.
The air compressor body is in this case of cast metal and the open ends described
serve to facilitate or contribute to the casting of such cylindrical body.
If only one lead off pipe be required the one end will be simply plugged or
stopped as shown at ', to the left hand side of Figs. 1 and 2.
With the said cylindrical body there are combined as part of the casting, hold-
ing down plates or lugs f, for securing the device in position and above the said
body are cast faces, flats or cars y, which serve as carriers or attachment means
for bearings h, for the air pump and driver device.
Following this construction the upper faces or bolting blocks will receive the
shoes or feet of bearings to carry the pump cylinder e, the piston d, whereof is
worked by a crank i and transmission gear k.
The cylinder is connected through a valve b, or double valves (ball valves for
instance) so as to lead in air to the pump cylinder and on the back stroke of the
piston to force same into the compressor chamber, but so arranged as to close
the said valve or valves before the second valve or valves c, opens or open upon
the return stroke.
The said inner valve or valves c, is or are connected by a drilled hole c', through
the cylinder body e, and connects or connect with the interior of the compressor
chamber a.
The crank is driven by gearing k, from a counter shaft, and motion obtained
through a pulley and band or by a hand wheel or other means as the case may
be, indicated at m, as a hand wheel.
The air tube or tubes leading to and through the regulating valve ³, to the
signalling device is or are carried from the compressor chamber a, through screw

page_text: caps applied on or to seatings on the cylinder body such as at 2, the same in the
drawings representing a stop cock and reducing valve w³.
Corresponding fitting is provided for the application of a pressure gauge and
also where desirable for the application of a safety valve w
According to the modification shown in Fig. 3 of this invention the ends n,
are cast and the cylindrical body a, is formed of sheet metal.
The cover and bottom plate are made with a flange o, to fit to the cylinder
bokly, and may be rivetted or be screw threaded and soldered or be otherwise
attached, to render the fitting air tight.
The air pump tube e and the valves b, c, are fitted to the base plate and operate
as follows: The air inlet valve b, is fitted to its seating and communicates
directly outside with the air and when the piston is lifted the air is drawn into
the cylinder e, but on the return stroke the said valve will close and the second
valve c, leading to the compressor cylinder will open by reason of the air forced
out therethrough from the piston cylinder into the compressor chamber.
The cover of the cylinder is fitted with a central cap or cover and air tight
stuffing box, to the opening, and the end of the piston cylinder c is secured at c',
and the piston rod d, passes out through such cover and cap.
The piston rod so extending will be fitted with a handle or be linked to a
crank to give the required motion, or hand lever may be fitted for operating the
pump.
On the top of the chamber a, is fixed the compressed air lead opening, and
the safety valve when such is used. ³, represents the reducing regulating valve,
in this case a screw down valve, serving the purpose of and corresponding to
of Fig. 2.
The main wire of this signalling device or sound emitter is connected to the
door, window or place to be guarded so that upon the connections being operated,
by disturbing the condition of quiescense of the signal or alarm, by electric wires
and contact, or mechanically; or if any place or thing has been disturbed, the
valve of the sound emitter or alarm will be released, so allowing the air to escape
from the compressor chamber w, through the lead pipe to effect the signal or
alarm.
The compressed air will be led away through a proper pipe attached to the
cylinder body or to the cap or cover of the said body, through the regulator valve
and thence to the sound emitter outside the building or to the watch box of the
attendant in charge as before indicated.
This air compressor may be attached by the lead off pipes directly to any signal
or alarm, or be connected to a secondary reservoir or reservoirs which will be con-
nected with the signal or alarm located at different parts of the building, or series
of buildings or compartments of a railway train or otherwise.
Thus the compressed air communication from the compressor will be constant
after the charging takes place and whilst the signal or alarm remains in normal
condition, but upon any disturbance of that condition, that is by opening of a
door, window, sky-light, strong-room, safe, cellar flap or cover, or cabin on board
ship, or a railway train or carriage, or omnibus or otherwise any place the access
to which is prohibited or restricted the signal communication will be given and
the tap or valve connected with the alarm will become opened to permit of the
escape of the compressed air to and through a whistle, syren, or other sound
emitter, and such sound will be continued during the time and until the attention
of the authorised parties, attendant, watchman or officer has been called.
Combined with the so actuated signal an electrical circuit and electric light or
gas pilot light can be employed which will be switched or turned on thus indi-
cating by the location outside of the premises or place, and also the alarm signal
can be given inside, all operating at the same time.
An electrical communication to operate an armature or to set free a spring, or
to release a weight to operate the compressed air tap or valve may in some cases
be employed if found desirable.
