Improvements in Audible Signalling Apparatus.
WILLIAM HICKIN, of the Firm of T. Hickin & Son, 83 Buckingham Street
Birmingham Brass Founders do hereby declare the nature of this invention to be
as follows:-
The object of my improvements in fog alarms & other such analogous articles is
to produce a long clear sound from a whistle or its equivalent & also to make
quick & short sounds by the action of an air pump & an air bag with or without
the air bag.
In carrying out my invention-I construct, any required air pump-to be worked
by hand, or otherwise. At the bottom of the air pump, I attach a stirrup foot-rest
or other base. Upon the air pump, towards its top, & near the working handle
I fix a bracket. Upon the pipe towards the bottom of the air pump, the outlet
valve, I screw an elbow thereon-in the bracket on the air pump, I place therein,
a brass stop-tap, & upon the end of this tap, I screw a whistle, or its equivalent→
I construct an air bag, for expansion-& contraction, having an inlet, & outlet,
tubes this air bag is made of india-rubber, or other suitable material, & covered
with, or without leather-or other substances. Thus, I place one end, of the
tubing, of the air bag, upon the elbow, leading, from the valve of the air pump-
& the other end, of the tubing of the air bag. Upon the end of the brass stop
tap which is held by the bracket, & the air bag, is suspended between, the brass
stop-tap & the elbow on the valve outlet-I work the handle, of the air pump-
while my foot, holds the stirrup-foot rest-& the air flows into the air bag-&
expands it, I turn the brass-stop-tap on, & there is a continuous flowing, clear
sound, of the whistle, or its equivalent acting as a fog alarm, to any approaching
vessels, or boat, or any other thing-& also emitting any call, or signal, which may
be required, either on sea, river, or land. When I do not want, to use the air bag,
I attach the whistle, or its equivalent to the elbow, at the outlet valve, on the air
pump & quick & short sounds are produced-when the air pump is worked.
It is understood, I shall adopt any mere modifications, that may be required in
carrying out my invention in fog alarms & other analogous articles & shall use
such required material, in the manufacture of such articles, that may be required
as brass German silver-iron, wood, india rubber-& such like equivalent
substances also instead, of the whistle, at times, I shall use gong's trumpet's,
horn's & such like.

COMPLETE SPECIFICATION.
Improvements in Audible Signalling Apparatus.
WILLIAM HICKIN of the Firm of T. Hickin & Son, 83 Buckingham Street
Birmingham Manufacturers, 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 object of my improvements in audible signalling apparatus is to produco a
ID071

page_text: long, & clear sound, from a whistle, or its equivalent, & also to make quick & short
sounds by the action of an air pump, & an air bag.
In carrying out my invention, I construct any required air pump, to be worked
by band, or otherwise. At the bottom, of the air pump, I attach a stirrup foot, or
rest, or other base, or air pump or apparatus may be held in any position, or even
held in the hand, or it may be fixed in either part of the vessel enclosed in a box,
by mean's of brackets, or otherwise upon the air pump, towards its top, & near
the working handle, I'fix a bracket & in this bracket, I place therein a brass stop
tap, or tube pipe-or any required connection, & upon on end thereof, I screw a
whistle or an organ reed, or the whistle's equivalent. Towards the bottom of the
air pump, the outlet valve, I fix or screw an elbow or any other connection.
I construct an air bag, for expansion, & contraction, having au inlet & an outlet
tubes or apertures, this air bag is made of indiarubber-or other suitable material,
& covered with or without leather or other substance.
Operation-thus I place one end of the tubing of the air bag, upon the end of
the elbow, leading from the valve, of the air pump, & the other end of the tubing,
of the air bag, upon the end, of the brass stop tap, or tube pipe or connection, which
is held by the bracket-& the air bag is suspended between the brass stop tap or
tube, or connection, & the elbow on the valve outlet pipe. I work the handle, of
the air pump, while my foot hold's the stirrup foot rest, & the air flows into the
air bag, & expands it. I turn the brass tap, on, or the connection is open, & there
is a continuous flowing clear sound of the whistle, or organ reed, or its equivalent-
& acting as a fog alarm to any approaching vessel, or boat, or yacht, or any other
thing, & also emitting any call or signal, which may be required either on sea, river
or land.
'
When I do not want to use the air bag- or the air bag, in case of accident is
damaged, I attach the whistle, or organ reed, to the elbow, at the outlet valve, or
I may use the organ' reed in my mouth as a fog alarm.
The accompanying drawing' illustrates my improvements in audible signalling
apparatus. Same letters of reference indicate corresponding parts. Fig. I repre-
sents my audible signalling apparatus. a. air bag. b. air passage, or tube end,
of the air bag, fitted on to elbow, of the outlet valve, or whistle or organ reed
connection, or tap. c. leather covering over the air bag, to protect, the india
rubber bag. d. elbow fitted, on to the pipe, of the outlet valve, of the air
pump. e the brass stop tap for turning on or off the flow of air, from the air
bag. f. the whistle, or organ reed. g. the bracket, holding, the apparatus to the
air pump. . the air 'pump. i. stirrup foot rest, fitted upon the bottom of the air
pump. k. the working handle of the air pump.
It is understood,' I shall adopt any mere modification, that may be required in
carrying out my improvements in audible signalling apparatus, & shall use such
materials in the manufacturing of such apparatus, that may be desired as brass,
German silver, iron, wood, india-rubber, leather zinc-& like equivalent substances
or instead of whistles at times I shall use trumpets horns & such like.
Having now particularly described, & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is―
1st. The use of an air bag, to produce a continuous alarm or worked as a signal
with such attachments that may be required.
2nd. The combination, of an air bag, with an air pump as set forth, described &
illustrated in the accompanying drawings.
