Salesman, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to give alarm at any Fire Station (or all if needed)
of the first stage of a fire at any house, and also at the same time to give alarm to the
house itself. We effect this by laying down wires in each street, connected with an
Electric Bell and Battery at any Station, the Bell bearing the name of the street,
whence the wires proceed; and offshoot wires from these into each house in the street
by carrying from top to bottom of each house, in the street, wires connected with a
bell and battery in the house, and by so arranging further wires in relation to those
named, and to an Electric push in each room in each house, that a fire breaking out in
any room, will bring about such action on the push there as to complete the Electric
circuits to the bell in the house and the bell at the Station. If thought necessary by
the Authorities over any Fire Brigades to avoid the number of Bells at any Station
the Bells can be concentrated according to their views.

Improvements in Electric Fire-alarums.
MARCUS ASH ISRAEL, 4 Nassau Street, Soho, London, W.C., Brass Worker
HENRY ASH ISRAEL, 37 Central Meat Market, West Smithfield, London, E.C., Meat
Salesman, do hereby declare the nature of our invention for IMPROVEMENTS IN
ELECTRIC FIRE-ALARUMS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
The object of our said Invention is to give alarm at Fire-Stations of the first stage
of the outbreak of fires as well as on the premises wherever they occur.
To effect our
object we run wires in pairs in each street continue these wires in pairs to the nearest
Fire-Station or Fire-Stations and connect them with electric bells and batteries there
set up so connecting them that the whence of each pair of wires is plainly indicated.
From the street wires we carry offshoot wires into each house of a street and continue
these house-wires from bottom to top of the house. Also from bottom to top of each
house we carry a pair of independent house-wires connected with an electric bell and
battery placed in each house. We then carry from each set of house-wires offshoot
wires into each room of each house and there connect them with an electric push in
such fashion that a fire breaking out in a room will bring about such action on the
electric push there as to complete the electric circuits to and set ringing both the
electric bell in the house giving alarm there and that bell at the Fire-Station that is
connected with the street in which the house is situate where the fire has commenced
giving alarm there also as well as making known to the Station attendants the closely
proximate whereabouts of the fire. We explain our arrangements to carry out our
purpose by the Drawings hereunto annexed.
Fig. 1 represents a street in plan each shaded block A, A, A, representing a house
and the lines ab and c d representing a pair of wires run in the street and carried on
by their band d ends to a Fire-Station represented in vertical section in Fig. 2. A in
Fig. 2 represents an electric battery and B an electric bell in the Fire-Station placed in
any convenient position say on a shelf affixed to a wall and the 6 and d ends of the
street wires are made continuous with the band d wire-ends of A and B. On the bell
is noted the name of the street whence the wires run. The offshoot wires carried into
cach house from ab and c d (Fig. 1) are represented by the lines ef and h
respectively. Fig. 3 represents a house in vertical section the lines ik and Im repre-
senting wires running on to the top of the house from respectively the wires ef
and appertaining to that house. The lines no and pq represent an independent pair
of wires running from bottom to top of the house and connected with the o and
ends of the electric battery C and bell D which are placed in any convenient position
in the house say by the top of the staircase. The lines rs and tv represent wires
running respectively from the wires ik and I m into each room of the house and the
lines w x and y z wires running respectively from the wires no and p q into each room.
The wires rs, tv, in x, and y z terminate in each room in an electric push E. Of this
wire-

push Figs. 4 to 7 give details of construction. The same same letters indicate the
same parts in each Fig. Fig. 4 is an elovation, Fig. 5 a plan Fig. 6 a plan of the
base A (Fig. 4) of the push and Fig. 7 principally a section on a plane passing per-
pendicularly through the line A' B₁ of Fig. 5. The cap B (Figs. 4, 5 & 7) of the
push screws to the base as shown in Fig. 7. We generally make A and B of wood
and the other parts of the push of metal. Attached by screws to the base of the push
so as to have one end free are four flat springs a, a, a, a, (Figs. 6 & 7) and the s, v, x,
and ends of the wires r, tv, wc, and y z are so arranged as to be severally in electric
contact with these springs. Fixed rigidly to the cap of the push is a light cylindrical
tube bb (Figs. 4, 5, & 7) open at bottom but covered at top in which works a piston ce
(Fig. 7) hollow but with bottom end closed of which the rod d (Figs. 4, 5, & 7)
terminates at its free end in a hook. Within the piston cc (Fig. 7) around its rod d
and setting against its closed end and the covered end of bb is a spiral ring e e.
Also fixed rigidly to the base of the push are two standards and y the standard
У
being flattened out at top (Figs. 4, 5, & 7). Hinged to is a lever hh which is
flattened out at its free end similarly to g and the hook of the piston rod d takes on
to hh. Referring to Fig. 7 it will be seen that the spring e e if left free would set
against the cover of bb and bring cc into contact with a, a, a, a, but between the
flattened ends of gand h we place a prop or stay of sealing-wax of such length
that cc is nori held out of contact with a, a, a, a. On the occurrence of a fire
however in a room fitted as described the stay k softens and bends or melts the
spring ee acts the piston c c comes into contact with a, a, a, a, and there is set up
a complete electric circuit in the house so that its electric bell is set ringing and also a
complete electric circuit to the Fire-Station in wire-connection with the house so that
the bell at the Station is set ringing too and the attendants there are informed both of
the occurrence of a fire and of its locality. For the stay k we do not confine ourselves
to sealing-wax other material being available fusible metal for example that will give
or melt at a temperature of about half as high again as the average of a room.
populous neighbourhoods additional circuits may he made to Police-Stations. Street
wires may in many streets he conveniently run under the copings of the houses.
Instead of noting names of streets on the bells at Stations the streets may be made
known by electric indicators.
In
Having now described and particularly ascertained the nature of our said Invention
and the manner in which the same is or may be used or carried into effect we would
observe that what we consider to be novel and original and therefore claim as our
Invention is
The giving alarm at more than one place at one and the same time of the outbreak
of a fire in the manner and by the means substantially as hereinhefore described.
