Improvements in Burglar or Fire Alarms.
I, NICHOLAS WAY, Junior, of 45, St. Germains Road, Forest Hill, London, S.E.,
Master Mariner, do hereby declare the nature of this invention to be as follows:-
I'drill a hole through a window frame or a hole through a brick or partition at
any convenient place in the room. Through this hole I pass a tube with a
flange at one end for holding same. At the flanged end of this tube I form a
stuffing box. Passing through this tube I have a second tube and this tube is
sufficiently long to pass out at the end of the first tube. At the end of this
tube I have a whistle or siren, and on the end of the tube inside the room I
have a reduced nozzle on which I attach a flexible tube of sufficient length to
reach to any part of the room that may be desired. On the end of the flexible
tube I put a mouth-piece, or a ball or cylinder with pistón. When one blows
through the flexible tube from the mouthpiece, the whistle or siren will give
out a shrill note. Or in the case of a ball being used by compressing it you blow
the whistle or siren, and you do the same by forcing the piston down the
cylinder, and the whistle or siren being out of doors will be readily heard by
the nearest policeman, and giving the alarm. By its construction the whistle
or siren can be withdrawn during the day when not wanted and a plug substi-
tuted in its place.
I do not confine myself exactly to the mode of construction but to the appli-
cation of a whistle or siren passing through a window frame, wall or partition for
calling.

Improvements in Burglar or Fire Alarms.
I, NICHOLAS WAY, Junior, of 45, St. Germains Road, Forest Hill, London, S.E.,
Master Mariner, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained. in and by the following statement:-
I drill a hole through a window frame or a hole through a brick or partition_at_
any convenient place in the room. Through this hole I pass a tube with a
flange at one end for holding same. At the flanged end of this tube I form a
stuffing box. Passing through this tube I have a second tube and this tube is

page_text: sufficiently long to pass out at the end of the first tube. At the end of this
tube I have a whistle or syren, and on the end of the tube inside the room I
have a reduced nozzle on which I attach a flexible tube of sufficient length to
reach to any part of the room that may be desired. On the end of the flexible
tube I put a mouth-piece or a ball or cylinder with piston, which may be placed
on the wall. When one blows through the flexible tube from the mouth-piece,
the whistle or syren will give out a shrill note, or by pressing the ball or push-
ing in the piston, the whistle or syren is blown and the aperture emitting the
sound being out of doors will be readily heard and give an alarm.
By its construction the whistle or syren can be withdrawn during the day
when not wanted and a plug substituted in its place.
In order that this invention may be more readily understood, reference is had
to the accompanying drawing which shows my appliance partly in section.
To the window frame or equivalent part A shown in section, I fit the tube
or socket B which passes through a hole in the frame and is screwed in position
by means of the flange b. The whistle C which may be of any suitable form fits
closely within this socket and extends at the outside for a convenient distance
the openings of the whistle being external to the window so that the sound when
the whistle is blown occurs outside the house.
The whistle is provided at its inner end with a nipple e to which the rubber
tube D is fitted. This tube can be of any length to extend to the desired part
of the room and can be secured along the wall if necessary. It is shown with the
mouth-piece d at its extremity but as above described any well known means
for producing. air pressure for the purpose of sounding the whistle can be fitted
in place of the mouth piece.
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) An improved burglar or fire alarm, consisting of a whistle or like device
secured in the window frame or other convenient part of a house having its
sounding end at the outside and a connection from the whistle inside the room
having means for supplying air pressure, substantially as and for the purposes
described.
(2) The improved burglar and fire alarm, consisting of a socket fixed in the
window frame or other part, a whistle fitted within the said socket and detachable
from it and adapted to sound outside the house and means for sounding the whistle
from inside, substantially as and for the purposes described.
Dated this Eighth day of June 1900.
