page_text: A New or Improved Fire or Burglar Alarm for Enclosed Places.
I, LOUIS MOREY, of 95, Battersea Rise, Clapham Junction, London, S.W.,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved fire or burglar alarm for enclosed
places the object being to set up a fire or burglar alarm (so called) externally
or outside of enclosed places, such as buildings, warehouses, dwelling-houses,
stables, repositories, and the like or similar places in such wise that the signal
or alarm will be sounded outside thereof, so as to call attention of the police
or watchman appointed for the purpose.
In carrying the invention into practice an air chamber is provided made of
metal, rubber or otherwise which said chamber is to be fixed or hung upon a
wall or as may be convenient or suitable for the purpose.
The said air chamber will receive compressed air, forced into same by pump
or otherwise, and in connection with the chamber there will be provided inlet
and outlet tubes or pipes or other suitable fittings. To the inlet will be connected
a valve or tap (spring, screw, or otherwise) and a suitable union to connect to
the filling a paratus or from a compressed-air-main or source of supply.
From the outlet of the chamber a pipe or tube is to be carried to the point
where the signal or alarm is to be located, such as to the frame of a door or
window, skylight, or whatsoever place, found convenient or requisite, to sound
the outside alarm for the watchman or police. Connected with the said pipe or
tube will be a valve or tap and a whistle, horn or other sounding device mounted
and attached exteriorly of the frame of the door or window by means of a plate,
flange or disc and screws.
Preference will be given to the employment of a whistle having the sound of
the ordinary regulation police whistle.
The signal-emitter whether whistle, horn, or gong, will be covered and pro-
tected by a hood or cover to prevent same being tampered with.
Connected with the alarm-valve or -tap will be provided a chain, lever or attach-
ment serving to operate or effect the sounding of the alarm when the normal
condition of the fittings. is disturbed; for instance the connection may be to,
either sash of a window or a casement, opening either inwards or outward, to
doors or other places or fittings such as skylights, or otherwise so that on the
places being disturbed the outside alarm will be forthwith sounded to call
assistance.
In case of the same being employed as a fire alarm, hooks or eyes may be
attached to fusible-plugs," sconces, or bosses of fusible metal and combined with
springs which upon being "set" and released would operate the alarm or signal
in case of fire.
It will equally will be understood that electrical connections
combined with and be set up for onerating the said outside olamni dani

page_text: In combination with the opening doors, sashes, casements, or the like catches
may be applied to prevent same being opened beyond a certain distance; or,
should same be closed again, it will not interfere with the operation of the
alarm.
The connecting chain, bracket, lever or attachment may be so applied as to
allow of its being detached by day and to provide for its ready connection at
night or other time when premises may be left without attendance and so as not
to interfere with the use of doors, windows or the like under ordinary conditions.
An indicator will be connected with the air chamber or outside-signal denoting
when the air chamber is fully charged and ready for use.
I, LOUIS MOREY, of 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 a new or improved fire or burglar alarm for enclosed
places, the object being to set up a fire or burglar alarm (so called) externally
or "outside of enclosed places such as buildings, warehouses dwelling-houses,
stables, repositories, and the like or similar places in such wise that the signal
or alarm will be sounded outside thereof so as to call attention of the police
or watchman appointed for the purpose.
In carrying this invention into practise an air chamber is provided made of
metal, rubber, or otherwise which said chamber is to be fixed or hung upon a
wall or upon the floor, on a bed plate or other point of fixture or as may be
convenient or suitable for the purpose.
The said chamber will receive compressed air forced into same by pump
or otherwise, and in connection with the chamber there will be provided inlet
and outlet tubes or pipes or other suitable fittings. To inlet will be connected a
valve or tap (pring, crew, or otherwise) and a suitable union to connect to the
filing a peratus, or from a cor pre-id-pir-main, or source of supply.
From the outlet of the chamber a pipe or tube is to be carried to the point
where the signal or alarm is to lur located, such as to the form of a frame of a door
or window, skylight, drawers, doors of safes, skylights, flaps of cellars, gates,
window blinds, or shutters, loose footboards or whatsoever place found convenient
or requisite to sound the outside alarm for the watchman or police. Connected
with the said pipe or tube will be a valve or tap and a whistle, siren, or other
sounding device mounted and attached exteriorly (of the frame of the door or
window or the like or in a wall or any call station) by means of a plate, flange or
dise and screws or bolts or same may be placed in a wall-box grating or cover.
Preference may be given to the employment of a whistle having the sound of
the ordinary regulation police whistle.
The signal omitter, whether whistle, siren, horn, or gong, bell or otherwise,
will be covered and protected by a hoed, cover, or grating, to prevent same from
being tampered with.
Con ete with the alama valve or tap will he provided a chain, lever, or attach-

fittings is disturbed for instance, the connection may be either sash of a window
or casement, or cover or plate opening either inward or outward, upward or down-
ward and to doors, or other places or fittings such as skylights cabins on board
ship, storerooms, railway carriages compartments or otherwise so that on places
being disturbed the outside alarm will be forthwith sounded to call assistance.
In case of the same being em, loyed as a fire alarm hooks or eyes may be attached
to fusible plugs, sconces or bosses of fusible metal, and combined with springs

or the like,
In combination with the openings deois, sashes, casements,
catches may be applied to prevent same being opened beyond a certain distance
or should same be closed again it will not interfere with the operation of the
alarm.
The connecting chain, wire, cord, bracket, lever, or attachment valve or push
may be so applied as to allow of it being detached or cut off by day, and to
provide for its ready connection at night or other time when premises may be
left without attendance and so as not to interfere with the use of doors, windows,
or the like screens or shutters for openinga, under ordinary conditions, as in
daylight when the chamber, house, warehouse, or premises, are in full or general
open use.
An indicator such as a gauge or a safety valve will be connected with the air
chamber or outside signal denoting when the air chamber is fully charged and
ready for use.
This invention is illustrated in the accompanying drawings, wherein :--

aforesaid, may be made of metal, as shown in Fig. 1, 2 & 10, or of rubber or other
elastic material as shown in Fig. 3, or of any suitable substance. The chamber a
may be fixed upon the floor as in Fig. 1, 2, 10, or be suspended from or hung
upon the wall or affixed to a hanging biarket e as shown in Fig. 3. It will be
obvious that the chamber a, however, for containing the air under pressure which
when released sounds the whistle, horn, or siren, may be of various designs,
shapes, or patterns, such as for instance, cylindrical, spherical, rigid collapsible,
telescopic, or otherwise all as may be most convenient or suitable.

page_text: Air is forced under pressure, into the chamber or reservoir a, through a suitable
inlet or passage way d (see Figs. 2 & 3) by means of a pump as e Fig. 3, or
a belles such as Fig. 3^, or any other suitable contrivance or means
as for instance a foot air pump a hand lever air pump, a circular
hand air pump, or the like or the air may be admitted directly
from a compressed air main or other source of supply. g is the com-
pressed air outlet tube leading to the whistle, siren or other sound emitter h
placed in any suitable position upon or in the wall, door or window frame, sky-
light, flap of cellar, gate, coal-plate, or other convenient part, of any building
to which the device may be applied.
i Fig. 1, 2, 3, 10, is the valve or cock controlling the outlet tube or pipe g
of the apparatus.
A suitable construction of valve for this purpose is shewn in detail in Fig. 7,
and the following is a description thereof is the valve seating kept up by
pressure in the vessel or reservoir a and by spring is the outlet pipe to whistle
or other sound emitter when the valve i¹ open; is a valve seating which is
down when valve is open and prevents air escaping through and allows it to
pass to pipe ³. The spring keeps valve up when weight is raised. is
the fulcrum upon which weight works. is the ton of valve where the
weight strikes. 28 are screw holes for securing the valve to the wall and 29
is a hole for wire connection from the windows and doors. As will be seen
upon particular reference to Figs. 1 and 2 the alarm valve or tap i is connected
by wires chain or cords k from the end of lever to catches the window, sky-
lights, doors, or other desired portions of, or positions upon, the building fitted.
Fig. 2 shows particularly a catch 7 well adapted for use upon windows sashes
and to which the connecting wires h may conveniently be attached.
m is the
sliding window frame, m¹ the stationary sash m² is a slot cut in the lever or
catch and in which works the pin m³ made fast in the wall. The slot only
allows the window to be opened a certain distance, the pin working therein catches
at end of slot and prevents the window orening farther at the same time it pulls
the wires in such manner as to open the valve i and cause the whistle to be
sounded by the escape of compressed air through the tube g to the sound emitter h.
But of course it will be understood that other constructions of catch, or means of
attachment of wire cord, or chain, to the window or windows may be employed if
found convenient or suitable without departing from this invention.
A form of catch suitable for a door is shown in Figs. 6, 6, 6³. is the catch
fixed upon door op is a weighted lever pivotted as at p¹ upon a supporting
bracket and set in position to give the alarm when the door is opened, q is
the wire leading thereirom to the alarm, r, rare grooved pulleys one with a
square hole in boss so that it can be turned from the outside and lift up the
lever p
By this arrangement the alarm can he set from the outside and also
be released, by turning the wheel r. The wire s running over to the lever p
lifts same high enough so that the catch misses it.
When employed in conjunction with fu-il pluggs this invention is applicable
as a fire alarm & in Fig. 8 is illustrated an arrangement of device so acting.

at 3, to a spring strong enough to balance plugs, t is a second bell crank con-
nected by chain to the main wire t, and is a wire connecting the two bell
cranks. When the plugs are melted the spring draws the wire and works the
crank and thus pulls wire t which is connected to air valve and will throw it
open and allows air to escape and thus sound the alarm. In addition to this
water tank supported upon angle brackets from the wall may be employed.
This tank shou'd be kept full say within an inch of the top and when the plugs
are melted and the spring tightens up it pulls lower r and opens water

x indicates the batteries y are the main wires running through the building and
z are the connecting wires running to main wires from the windows, doors, etc.
There is a continuous current through all the wires so that when a window, or
door, is opened the current becomes broken and the magnet that holds the valve
in position ceases to operate and therefore the weight falls over and opens the
valve thereby allowing the air to escape to the alarm.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The new or improved fire or burglar alarm for enclosed places as and for
the purpose specified.
2. In a fire or burglar alarm the air reservoir with inlet and outlet valves in
connection with a whistle or other sound emitter operated by, and in combination
with suitable wires or their equivalents and attachments connecting the windows,
doors or the like, with the outlet valve of the air compresser, or compressed air
supply all arranged, constructed and operating as and for the purposes herein set
forth, described, and shewn.
