PROVISIONAL SPECIFICATION.
Improvements in Whistles and Foghorns.
I, WILLIAM BENJAMIN BARKER, of 19 Bullins Terrace, Marsh Lane, Bootle,
in the County of Lancaster, Master Mariner, do hereby declare the nature of
this invention to be as follows:-
:―
This invention has for its object to provide a simple, inexpensive, and improved
whistle or foghorn, or improvements connected with whistles or foghorns, of the
type or kind in which two or more notes are produced.
In a whistle or foghorn according to this invention, two or more notes are
sounded, and the sounding parts are of cylindrical form, and in two or more parts,
both or all of which are on the same axis longitudinally; and, in the case of a
vertical arrangement, are one above another.
According to one arrangement, as applied to whistles or foghorns of the tubular
type with the openings in the side thereof, the tubular portion is divided, or made
up of parts, and the steam or air is conveyed or controlled by a single valve to the
different parts or chambers, this being preferably done by providing an inner tube
or tubes which pass up into the second chamber or other chambers, from the lower
one. In one case, the division may be in the form of a plug filling the tube, and
through which steam is conducted and discharged near or adjacent to the openings
in the tube, and the steam is led to this plug by an inner tube which is carried
down from said plug to near the valve. Above this valve a second plug, with
openings or cuts adjacent to the openings in the lower whistle, is provided. The
valve seat is provided on a flange, which flange is fastened to the flange of the pipe
supplying steam or air to the whistle or horn. The valve, in one case, is operated
by a spindle passing down through the whistle and inner tube, it being suitably
operated by a bell-crank lever connected with said spindle.
By this invention, condensed water in the steam pipe (in case of steam being
the fluid used) is more easily and quickly got rid of, and consequently, the whistle
or horn gives sound more quickly and clearly. By arranging the different parts
which give the different notes in line axially as described, a simple and cheap
instrument is provided; and moreover when made, the parts, arranged as described,
are easily coupled up and taken to pieces.
In one modification, a foghorn under this invention consists of a duplex or
multi-note sounding device of the kind above described, combined with 'an
expanding horn, the device being disposed in the smaller or inner part thereof.
The improvements herein described may be applied to other forms of whistles or
foghorns, than the one hereinabove referred to.

I, WILLIAM BENJAMIN BARKER, of 19 Bullins Terrace, Marsh Lane, Bootle,
in the County of Lancaster, 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 ascertained in and by the following statement:-
This invention has for its object to provide a simple, inexpensive, and improved
whistle or foghorn, or improvements connected with whistles or foghorns, of the
type or kind in which two or more notes are produced.
In a whistle or foghorn according to this invention, two or more notes are
sounded, and the sounding parts are of cylindrical form, and in two or more parts,
both or all of which are on the same axis longitudinally; and, in the case of a
vertical arrangement, are one above another.
According to one arrangement, as applied to whistles or foghorns of the tubular
type with the openings in the side thereof, the tubular portion is divided, or made
up of parts, and the steam or air is conveyed or controlled by a single valve to the
different parts or chambers, this being preferably done by providing an inner tube.
or tubes which pass up into the second chamber or other chambers, from the lower
one. In one case, the division may be in the form of a plug filling the tube, and
through which steam is conducted and discharged near or adjacent to the openings
in the tube, and the steam is led to this plug by an inner tube which is carried
down from said plug to near the valve. Above this valve a second plug, with
openings or cuts adjacent to the openings in the lower whistle is provided. The
valve seat is provided on a flange, which flange is fastened to the flange of the
pipe supplying steam or air to the whistle or horn. The valve, in one case, is
operated by a spindle passing down through the whistle and inner tube, it being
suitably operated by a bell-crank lever connected with said spindle.
By this invention, condensed water in the steam pipe (in case of steam being the
fluid used) is more easily and quickly got rid of, and consequently, the whistle or
horn gives sound more quickly and clearly. By arranging the different parts
which give the different notes in line axially as described, a simple and cheap
instrument is provided; and moreover when made, the parts, arranged as described,
are easily coupled up and taken to pieces.
In one modification, a foghorn under this invention consists of a duplex or
multi-note sounding device of the kind above described, combined with an
expanding horn, the device being disposed in the smaller or inner part thereof.
The improvements herein described may be applied to other forms of whistles or
foghorns, than the one hereinabove referred to.
In the drawings illustrating this invention, I shew three modifications.
In Figures 1, 2 and 3 is shewn a whistle or foghorn by which two notes or
sounds are given out. Of these, Figure 1 is a sectional elevation; Figure 2 is a
detail in section of the lower part of the apparatus; and Figure 3 a plan at the
line A A Figure 2.
Figure 4 is an outside elevation shewing a modified form of whistle or fog-horn
shewn in Figures 1 to 3; and Figure 5 shews another modification.
The same letters and figures of reference are used to denote the same or equivalent
parts wherever they occur in the drawings.
Referring in the first instance to Figures 1 to 3, a is the case of the whistle, and
it may conveniently consist of a length of ordinary tube. Within this case there
is at the bottom a plug e, and half way up another plug i, these plugs practically
filling the tube, and forming the space within it into lower and upper chambers b
and c.
The plugs e and i have within them the spaces f and j, and these spaces are

page_text: connected together by the internal tube d. The lower plug e has a threaded neck e'
upon it; and is fastened or secured to the flange m by this neck e', which screws
into the flange.
The supply of steam to the whistle is controlled, and admitted to the chambers b
and c, by the valve n, the face of which rests, when closed, upon a seat on the
lower edge of the neck e'; and it is moved onto and off its seat by a spindle o,
which passes from the valve n up through the tube d, the plug i, and the cap h, of
the chamber c; and its operation is effected by the lever p.
Steam passes from the chambers f and j of the plugs e and i into the sounding
chambers b and c through peripheral apertures g and k, the said apertures being
disposed adjacent to the openings b and c in the case a, so that the steam flows
from the apertures g and k upwards along the plane in which these openings are
disposed. According to the notes or tones required to be sounded, so will the
openings for steam and the relative sizes and lengths of the chambers of the whistle
be made.
As regards the manner of construction of this apparatus, the flange m forms
a base for the whole device. Into it is first screwed the plug e, and this plug,
together with the tube d and plug i, forms a support to the casing a, the casing, in
construction, being fitted over the plugs i and e.
In the modification shewn in Figure 4, there is combined with the whistle a
sound directing hood r, by which the sound is caused to take a horizontal
direction; and so, in the case of the application of the invention to a ship, is caused
to be propagated outwards from the vessel; this hood however per se forms no part
of the present invention, it being set forth and covered under the Specification of
my former Letters Patent No. 604 of 1895. The steam in this case may be
conveniently admitted to the interior of the whistle by a valve n¹ secured to the
under side of the flange m, as in ordinary whistles. In other respects, the
construction of whistle is the same as that set forth with reference to Figures 1
to 3.
Referring now to the modification shewn in Figure 5, this consists of the
multi-note sounding device or whistle of the kind above described, combined with
an expanding horn. In this case, the whistle shewn is a double note whistle with
two openings and c', plugs below the openings and c¹, and a plug h above,
forming a roof to the upper chamber of the whistle. Outside the whistle is the
horn shaped tubes, such horn extending from the flange m for a considerable
distance above the upper part of the whistle proper, the tube a, forming the case
of the whistle, being also carried up, so as to make the space existing round the
whistle proper-i.e. between the case a and the tubes unbroken for the whole
length of the apparatus, and so obviate any break in the passage for the travel of
the sound, and prevent thereby defective sounding of the apparatus.
The upper
part of this extended portion of the case a is carried outwards or expanded at a³,
as shewn. Steam would, in this case, be admitted to the whistle or apparatus by
a valve below the flange m in the ordinary way.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A fog-horn or whistle adapted to give two or more sounds or notes, having
sounding parts arranged one upon the other, or in line, substantially as herein
described.
2. A fog-horn or whistle adapted to give two or more sounds or notes, consisting
of or comprising a case, and, plugs at different points in said case, and connected
together by a tube, through which the steam is conveyed from the point of
entrance through the first chamber to the second or others beyond; substantially
as described.
3. The fog-horn or whistle, particularly as set forth with reference to, and
shewn in, Figures 1 to 3, and Figure 4, of the drawings.

page_text: 4. A fog-horn or whistle adapted to produce two or more sounds or tones,
comprising sounding parts arranged one above the other, and an outer expanding
horn, arranged and operating substantially as described.
6. The fog-horn or whistle, particularly as set forth with reference to and shewn
in Figure 5 of the drawings.
