PROVISIONAL SPECIFICATION.
A Burglar Detector, Fire Alarm, and Police Call.
WILLIAM WRIGHT Police Constable of 170 High Street Notting Hill, in the
County of Middlesex do hereby declare the nature of this invention to be as
follows:--
I construct of wood, brass, copper and zinc, an automatic machine by means of
which any person attempting to enter any premises to which it is affixed, will at
once arouse the inmates, and at the same time call the attention of the police in
the surrounding neighbourhood to the fact of their having made the attempt to enter:
such premises.
Or in case of fire, or any other emergency may summon police assistance,
immediately by simply turning a handle or bell pull without leaving their chamber..
And I construct it in the following manner.
I take two pieces of wood (oak by preference) one inch in thickness, one piece
5 ins. wide and 7 in length the other 4 ius. wide and 7 ins. in length. Both of
which, I encase in stout sheet brass, in the wider one I drill 2 holes inch in
diameter and insert in each an india rubber buffer 1 inch in diameter this I call.the
bed. To the other I affix with screws a 5 inch strong spiral spring, encased in
brass and working on a pivot, with a triangular piece 5 ins. in depth the same as a
door spring, with 4 holes for screws, which when screwed to the bed I call a stage.
1.next drill 3 holes in. in diameter right through the stage at the back, one in
the centre and close to the edge opposite the spring, one 14 in. from the right side
and 1 in. from the back. I take a piece of ins. brass wire, 3 ins. in length and
drill a small hole at the top and solder a ring 1 ins. therefrom as a check, which I
place in the hole as an upright piston or lever. I next take an ordinary pistol
with a trigger with the flat side outwards, and drill a hole through same. 1 take
3 pieces of brass and form them into a cradle for butt of pistol, which I solder
onto the stage at edge near spring and opposite upright. I. drill a hole through
stage in centre of cradle, and pass a 1 in. brass screw through same into butt of
pistol thus securing it in an upright position with two additional screws through
cradle at sides. I then take 2 brass screw pulleys small with grooved wheels, and
screw one each side of pistol into stage, and pass a piece of twice laid brass wire
through hole at top of upright pulley at right side, through hole in trigger and
pulley on left side of pistol knot and secure the ends with brass binding wire, this
I call my trigger lever. I drill the other hole 1 in. from the back and left side
edges, and take a piece of brass wire 4 ins. in length, and drill a small hole at
top, which I bend to form the segment of a circle. I take a 1 inch iron spring.
hook, and pass a piece of brass wire through eye of same and hole at top of wire.
and secure it with solder, and pass it through hole at back, this I call my rocket
lever I then screw a small brass screw eyelet onto stage at side of rocket lever,
and screw a small circular brass plate at back for a recoil plate. I then take a
piece of 1 in. copper tube 3 ins. in length, in side of which I cut a slot 1 ins. deep, .
by in. in width and solder a brass rim at top. I then cut a round piece of brass
and drill a in. hole in centre in which I solder a brass screw. I then solder the
whole into tube for a bottom. I next drill a small hole in copper tube in. from
the bottom. I drill a small hole in stage near left side and screw in the tube for a
rocket tube. I next take a piece of brass tube ins. in diameter and 9 ins. in
length in one end of which I secure a small grooved wheel, the other end I secure
in hole at back of stage for a lift for lid of case. I next take a piece of 1 in.
copper tube 14 ins. in length, to which I solder a brass rim. I then cut a circular...,
•

page_text: piece of brass, and drill a hole in. in diameter in which I secure a dowel screw
and solder the whole into the tube for a bottom, and screw it into the stage 1 ins.
from left side of pistol, for a blue light socket. I next screw into stage between
socket and lift a brass loop handle for raising stage when required, I then take a
piece of brass 3 in length, in. in thickness, ins. wide, in one end of which I
secure a stout brass hook, and drill a hole in the other, and one in the centre, and
rivet a length of brass chain in the hole at end, this I call the main lever and
communicator, I then drill a hole 1 in. from the back, in side of stage, and screw
on the main lever.
I next make a case of wood, 18 ins. in length 10 ins. in width, and 7 ins. deep,
and line the bottom with No. 25, sheet brass, the remainder I line and cover with
zinc, in lid of which 1 fix by means of a bracket and eyelet, a piece in. brass
wire as a traveller for lift. I then bore a hole in end of base in. in diameter, and
insert a short length of steel tube as a lead for chain communicator.
I then screw
a small brass pulley into bottom of case, in a line with and 4 ins. from tube as a
lead for communicator. I next bore a hole in diameter 8 ins. from end, and 1 from
side through bottom of case. I then take a piece of brass rod 6 ins. in length and
cut a thread 1 in. in length at one end, and place a fly nut and a square ditto
thereon. I then pass the end through hole in bottom of case, and secure with brass
nut outside, and locking same inside with the other nuts. 1 then cut a strip of
brass, 6 ins. in length, ins. in width, and drill a hole at each end.
I pass one end
overrod, and screw the other to bottom of case, these I call a stanchion and
stay. I also take a in. brass ring, and a stout piece of brass 14 in length and
wide, and drill a hole at each end, which I rivet to ring, and pass a copper
tube 1 in. in length through the other as a precautionary charge or communicator
from pistol to blue light, the ring being placed over barrel of pistol. I next
place the machine in case at end near tube, and secure it by means of 12 in.
screws through bottom of case. I then take a square stick in. in thick and
3 ft. 6 ins. in. length, and cut. it into 4 lengths 31-21 ins. in length, and
1-4 ins. in length and join them with hinge plates to fold up at side of bed at
bottom of case, the short length I screw into small tube at side of a 4 oz. signal
rocket with whistle attachment, and place and fasten a firing charge, composed of
equal parts of sulphur chlorate of potash, and nitre at end of rocket and place it
in copper rocket tube. 1. then place a copper friction tube through eyelet with
end in hole of rocket tube and hook the eye at other end on to spring hook of
rocket lever. I then take a friction blue light, and screw it into copper socket at
side of pistol. I then place a blank charge of gunpowder in pistol which I cock,
place a percussion cap on nipple. I next fill small copper tube of precautionary
charge with gunpowder, place ring of same over barrel of pistol with one end of
tube resting on barrel of pistol the other on top of blue light, which I encase in water-
proof paper.
I then raise stage perpendicular. Place the hook of main lever over
stanchion and the machine is ready for action. The machine is connected to doors,
windows etc. by means of springs, wires, and cranks, according to construction of
premises.
And the advantages claimed for this my invention, are these, that at any house
or other premises to which it is affixed any would be thief, attempting to open any
doors, or windows to which it is connected not only alarms the inmates but gives
immediate information to the police not only on that but surrounding beats.
As the moment, he raises a window or opens a door, the whole machine is set in
motion, the lid of case flies up, the pistol is discharged with a loud report which
calls attention. The rocket flies up in the air about 300 ft. thus shewing the police
the direction in which their assistance is required. The blue light is ignited and
brilliantly illuminates the neighbourhood of the house, thus indicating the actual
house where the attempt has been made, and rendering the escape of the thief.
highly improbable as the light is so bright, that he would be discernable from a
considerable distance.

page_text: Or in case of fire, or any other emergency the machine could be set in motion by
the occupier, simply turning a handle or pull, fixed over their bed, and are thus
enabled to summon police aid without leaving their chamber. The whole is
weather proof.
WILLIAM WRIGHT.
A Burglar Detector, Fire Alarm, and Police Call.
WILLIAM WRIGHT No. 170 High Street, Notting Hill London, in the County
of Middlesex Police Constable 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:-
I construct of wood copper, brass and zinc an automatic machine, by means of
which any person attempting to enter any premises to which it is affixed, will at
once arouse the inmates, and at the same time call the attention, of the police, in
the surrounding neighbourhoods, to the fact of their having made an attempt to
enter such premises. Or in case of fire, or, in any case of emergency may summon
police assistance immediately by simply turning a handle, or bell pull without
leaving their chamber.
And I construct it in the following manner. I take two pieces of wood oak by
preference, one inch in thickness, one piece 7 inches in length, and 6 ins. in width
the other 7 inches in length and 4 ins. in width, both of which 1 encase in stout
sheet brass in the wider one I drill two holes and insert in each an india-rubber
buffer T, this I call the bed A. To the other I affix with screws, a strong spiral
spring S. encased in brass, and working on a pivot, with a triangular piece 4 inches
in depth, the same as a door spring, with holes for screws, which when screwed to
the bed A. I call a stage B. I next take a piece of brass wire to form a sliding
piece C. to which I fix a wire cord d'. I next take an ordinary pistol P. and
twist the trigger flat surface outwards, through which I drill a small hole. I then
take 3 pieces of sheet brass and form them into a cradle for butt of pistol, which I
solder onto stage at edge near spring S. and opposite sliding piece C. I drill a hole
through stage in centre of cradle, and pass a stout brass screw through same into
butt of pistol thus securing it in an upright position with 2 screws through cradles
at sides I then take 2 small brass pulleys with grooved wheels d. and screw one
each side of pistol into stage. I next take the wire cord d' through right side of
sliding piece C. through pulley and hole in the trigger of pistol from right to left
then through pulley and sliding piece on left side and secure ends at back of same.
I next take a piece of brass rod, and bend it in shape of a straight arch E, which 1
pass through boles in stage B. In centre of arch I secure a spring hook E'. I
then fix a tube guide F. to the stage B. and insert a friction tube in the tube F,
and connect the friction tube to hook E'. I next take a piece of copper tube G. and
solder a brass rim at one end, and cut a slot in, side of same. I then cut a circle
of stout sheet brass, and drill a hole in centre in which I secure a stout screw.
I then secure same in end of tube by solder or other means for a bottom and drill a
hole in copper tube to receive the friction tube. I then screw the large tube G.
close to left side, and solder it to stage B. This I call my rocket tube. I next
take a piece of copper tube, H. to one end of which I solder a brass rim. I then
cut a circular piece of sheet brass and drill a hole in centre in which I secure a
dowel screw, and solder the whole into the other end of tube for a bottom and
screw it into stage to form a blue light socket. I next fix a rod j carrying
a brass grooved wheel j at back of stage to form a lift to lid of case.
I next
screw a brass loop handle K. at back of stage for raising the same.
I rivet a
lever to the side of the stage B, in one end of the lever I secure a stout brass

page_text: hook L¹ to hook over stanchion M. I attach a length of brass chain L" to the
lever I to start the apparatus.
I next make a case of wood and line the bottom with sheet brass, the remainder
I line and cover with zinc in lid of case I fix by means of a screw eyelet a piece
of brass wire to guide the pulley J. I next bore a hole at end of case and insert
a short length of brass tube as a lead for chain L" of communicator.
I then screw
a small brass pulley L³ into and inside of bottom of case as a further lead for chain
communicator. I then take a piece of brass rod M to form the stanchion, and cut
a screw thread at one end and place a square and fly nut thereon. I then pass the
end through a hole in bottom of case and secure with a square nut outside and
locking with fly nut inside. I then fix a strip of sheet brass M' as a support for
stanchion. I next take a brass ring N to fit over the pistol muzzle, with a
projecting piece carrying a short piece of copper tube N' to contain powder &c. for
the purpose of firing the blue light, when the pistol is discharged.
I next place the machine in at end near tube and secure with screws through
hottom of case. I then take a square stick and cut it into 4 lengths R and join
them with hinge or rule plates, to fold up at side and bottom of case, and form a
stick for the rocket R. I then make a firing charge of equal parts of sulphur,
chlorate of potash, and nitre, which I fix to bottom of rocket and place it in rocket
tube at side of stage. I next take a friction blue light V. and screw it into copper
tube H at side of pistol. I then load pistol with a blank charge of gunpowder and
place a percussion cap on nipple. I next fill copper tube N1 with gunpowder or
other combustible & place ring of same over muzzle of pistol with one end of
tube N secured to top of blue light which I encase in waterproof paper. I then
by means of handle K raise the stage B. to a perpendicular position, and place the
hook of lever Lover stanchion M, and the machine is ready for action. The
machine is secured by iron brackets or other suitable means to the outside of any
upper window, or on the roof of the premises, and can be painted to resemble a
bird cage, or flower box etc. The tube of case is passed through the outer wall
into the inside of premises, and is connected to the doors and windows, by means
of wires and cranks or by electric wires at discretion of occupier according to
construction of premises.
And the advantages claimed for this my invention are these at any house or
premises to which it is affixed, any would be thief attempting to open any door or
window to which it is connected not only alarms the inmates but gives immediate
information of the fact to the police on surrounding beats for the instant the door
or window is opened a few inches the machine is set in motion. As the lever L
becomes detached from the stanchion M. the lid of case is raised by the rod j. and
the stage B. assisted by the spring S falls down on bed A. As the parts C. E
project through the stage B. they are pushed upwards thereby pulling the trigger
and operating the firing tube, and the pistol is discharged with a loud report to
call attention. The rocket flies up about 31 0 feet, into the air, thus showing police
on surrounding beats the direction in which their assistance is required. The blue
light is ignited and brilliantly illuminates the neighbourhood thus indicating the
actual house where the attempt has been made, thereby rendering the escape of the
thief highly improbable as the light is so bright that he would be discernable at
considerable distance and his description obtained, or in case of fire, or other
emergency the machine could be set in motion by having a connection to the bed
chamber when the occupier by simply turning a handle could summon police
assistance or call the fire brigade without leaving his bed, and the whole can be
connected and disconnected at leisure by means of a spring hook and eye attached
to the wires. The whole of the combustibles are weatherproof.
Having now fully ascertained the nature of my said invention, and how the same
is to be performed, I declare that what I claim as my invention is
A machine for the purpose of preventing and detecting burglaries and calling

page_text: police assistance, or in case of fire the fire brigade, or in any case where
immediate assistance is required, and that the whole is constructed substantially
in the manner above described and for the purpose stated in this my Complete
Specification.
