We, GEORGE WILLIAM PHILIPSON, formerly of 23 Sprowston Road, Forest
Gate, but now of "South Side," Southchurch Road, Southend, Bank Accountant,
and GEORGE AMBROSE PHILLIPSON and JOHN HUGH BLO18, both of 40 and
42 Woodgrange Road, Forest Gate, Electricians and Cycle Manufacturers, all in the
County of Essex, 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 invention consists of the combination of an electric bell, electic lamp, and

page_text: suitable switches and contacts, so arranged that an alarm by both bell and lamp
can be given either automatically or optionally or both.
The apparatus is designed to give public notification and alaim of danger
fiom fire, burglary, or other imminent and critical sources of danger to property
and person.
In carrying our invention info effect we preferably mount an electic bell and an
electric lamp on the same baseboard or plate, and we fit a lamp o lantern
(preferably of red glass) over the electric lamp or over both bell and lamp and fix the
same in a conspicuous position on the premises or property to be guaided, so that
passers-by would, by hearing the bell and seeing the light, be informed that aid
was requined within such premise. The hell is connected by conducting wires
with a battery, and the lamp, by other conducting wires, with any suitable supply
of electricity. In the course of the several conducting wires we interpose pushes,
switches on contacts, at suitable places capable of being automatically operated by
any usual arrangements in case of fire, burglary, &c., and we also interpose at any
desed points manually operated pushes, switches or contacts, so that an alarm can
be given by a person in charge The pushes, switches or contacts, are two-fold
so that by a single action both currents can be closed and the electric lamp and bell
be simultaneously operated.
If desued the apparatus may also he caused to communicate with a fine-station,
police-station, or other desired place

and Fig. 8 is a vertical section, of a double automatic switch to be operated by
doors of sales, windows, &c, and connected with both alam-bell and lamp.
Fig 9 is a plan and Fig. 10 is an elevation of a metal case enclosing the double
automatic switch shown at Fig. 5 to 8
Fig. 11s a front view and Fig 12 a side elevation of a double optional
switch to turn the two currents for the alarm on and off as may be required
Fig. 13 is a face view of the dial case and lever of the switch shown at Figs 11
and 12
Fig. 14 is a diagram showing one manner in which the alarm and snitches may
be manged for use in a building.
The alarm represented at Figs. 1, 2, 3, which is to be placed in a conspicuous
position on the outside of premises to be protected, is constructed as follows:-
a is a base-board or plate on which are mounted a bracket & carrying an
Incandescent electic light e, and a bracket d caying an electite belle with its
mechanism, are the connecting wies to the bell from the terminals ff.
and g g are terminals connected with the lamp bracket b. The terminals ftale
connected with the bell line wires, and the terminals g g with the lamp line wires.
The bell and lamp mechanism ale of any ordinary constinction and separately
form no part of our present invention. The bell and lamp may be enclosed in
a lantern a¹ of the form represented at Figs. 1, 2, 3 o1 of the form represented at
Fig. 4.
The double automatic switch represented at Figs. 5 to 10 19 constructed as
follows.―

his an insulating block, are contact surfaces fixed to the block and inter-
posed in the electric light cu cunt, and are other contact surfaces also fixed to
the block and interposed in the bell encuit, is the contact budge for the
electie lamp en cunt, and is the contact budge for the electric bell circunt, these
bridges are canied by the spindle m, on which is also mounted the operating
levei n
o is a spring acting upon the lever n with a constant tendency to retain
and return it and the contact biidges to the contact on
position, whilst an
aim p fixed to or operated by the door of a sale, or other door, window or movable
"

page_text: article, acts, when the door, window or the like is closed or otherwise placed in
position of security, to force the lever n and contact bridges k l to the "curent off"
position, Figs. 9 and 10, is a metal case enclosing the automatic switch above
described and provided with a slot 2 to enable the aim p to enter the case and act
on the levet n. The bridges klare insulated from, and caused to move with, onch
other in the manner represented at Fig. 8, that is to say, the bridge is fixed
igidly to the spindle mand the budge is 11gidly fixed to an insulating block l'
which is centrally bored to fit the spindle m and is caused to move with the latter
and with the bridge by a pin from the latter bridge passing into a hole in the
block . The bridge is insulated from the spindle m by a short sleeve forming
part of the block and passing into a hole formed in the centre of the bridge 7.
The lever n is insulated from the spindle m by a sleeve o collar n, and is
connected to an insulating block n by two pins n¹ passing from said lever into
boles formed in the block, and the latter is grooved across its underside to fit the
centic part of the bridge 7, the lever n is fixed in position on the spindle m by
means of a nut m' which secures the two bridges and the insulating blocks, as also
one end of the spring o, in proper relative position on the spindle m, thereby
causing all such parts to move with the spindle The other end of the spring o is
fixed to a post ³ fixed to the insulting block h. The spindle m passes through
a sleeve m² fixed to the block h, and is acted on at its lower end by springs m³
to force the bridges & into close contact with the contacts (1) tespectively.
The double regulating and optional switch_represented at Figs 11, 12, 13, 1s of
similar construction to the switch shown at Figs. 5 to 8, like parts being indicated
by similar letters of reference m all the figures, the pincipal differences being as
follows:-
The lever n in Figs 11, 12, 13 is of suitable form to be operated by hand and is
mounted above a dial g, which is provided with stops qq to limit the motion of
the lever n and with the words "On" and "Off" to indicate the effect of the lever
in either of its two extreme positions, whilst the sping o is dispensed with. It
will be evident that the switch shown at Figs 5 to 8, by simply removing the
sping o, could be used as an optional switch.
In both forms of switches the contacts are connected by wires with the
terminals, and these latter are connected by wires 33 with the electric light
circuit, and the contacts are connected by wies with the terminals ²², and
these latter are connected by wies 3 with the bell encuit.
Jn Fig. 14, which represents a vertical section of a house or similar building
fitted with our improved alarm and fittings, A. represents a safe or strong 1001n,
B a battery and conductors for the bell circuit, conducting wires of the light
circuit, D the combined bell and light alarm, E an automatic double switch fixed
in the interior of the safe, Fan optional double switch for breaking the circuits
before opening the safe in order to avoid giving a useless alarm, and FF optional
double switches for enabling the occupants of either of the 100ms fitted with the same
to raise an alarm in case of fire, illness, thieves, or other danger or necessity. The
bell and light conducting wes are led into the back of the safe or strong room A,
and are connected with the automatic double switch E, which latter is inter posed
in both cucuits and is placed in the "contact off" position by means of the arm p
attached to or operated by the door of the safe or strong room.
The optional
double switch F is also inter posed in the bell and light circuits and may be placed
in any suitable position and locked up for security. Thus, when closing the safe
or strong-room door, the automatic double switch E is thereby set to the contact
off" position and the optional double switch F 1s set by hand to the "contact ou
ot to line "
position, so that if the safe door were opened while the switch F
were in this position, the currents would pass to the bell and lamp and so give an
alarm. When however it is desned to open the safe for business purposes, the
Switch Fis first placed by hand to the "contact off" position, after which the safe
door can be opened without giving an alaim
