Improvements in Kettles.
I, RIVERS DUNNETT of Bristol Street Birmingham in the County of Warwick,
Manufacturer:-Do hereby declare the nature of this invention to be as follows:-
My invention has for its object, the making of a single kettle useful for two
purposes; viz. :-a vessel for boiling or heating, and a vessel for generating steam,
for bronchitis purposes.
Thus my invention, which is an improvement upon application for Letters Patent
made by me on the 3rd day of August 1888 No. 11247, consists 1st, of a lidless
kettle, with a combined spout and filler, and when so made, is used as an ordinary
kettle. 2ndly, in converting the said vessel into a bronchitis kettle, or apparatus
for charging the atmosphere of a room with steam or vapour, to render the same
humid.
By my said improvements, as hereinafter described, steam does escape from the
spout, as in ordinary kettles, so that the same cannot boil over, as the steam generated,
is collected at the rear top part of the vessel, which has a ventilating tube or
whistle.
In carrying out my invention, I take an ordinary closed vessel, of the shape of a
kettle, and with the front top side, or that part sloping from the crown, provided with
a jug or funnel shaped spout, which does duty as a spout for pouring, and as a funnel
for filling.
The neck of the spout, which is considerably contracted, is extended downwards
into an open ended tube, which comes within an inch or so of the bottom of the
vessel.
By thus providing the spout with a water outlet only, steam generated is always
kept away from it, and is allowed to escape only through a tube or opening in the top
rear part of the vessel.
The ventilating or steam pipe is directed rearwardly, and through the back upright of
the handle, as a support.
The said ventilating tube, may be fitted with a whistle or alarm, which whistles or
indicates when steam is given off, or water boiling.
The open top of the spout may have a close fitting lid, hinged preferably to the
inner side, and in such a manner, that when pouring, the lid moves away, and after
pouring, the entrance to the spout is closed.
Instead of a depending tube proceeding from the spout to near the bottom of the
vessel, a half-round or other shaped passage may be substituted therefor; this said
passage, which cuts off the front, from the back of the vessel, where steam accumulates,
is made of a trough-shaped shell, soldered at its opposite edges to the front inside of
the vessel.
In a bronchitis kettle, the top or crown of the vessel is fitted with a short thick
swivelling ventilating tube, and to which, the inner bent end of a length of tubing
is fitted, and to the end of this said tubing, another length, or the spreader, is
fitted.
The kettle, as well as having a spout from which to pour, and with which
to fill, may be provided with an ordinary spout, so that the funnel spout is used for
filling only.
Lidless kettles so constructed and provided, are safe, and free from danger, as

page_text: they cannot boil over, as the steam generated is allowed to pass away at the back;
and further, when the water therein boils, it is indicated by the sounding of the
whistle or alarm.

Improvements in Kettles.
1, RIVERS DUNNETT of Bristol Street Birmingham in the County of Warwick
Manufacturer, 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 relates to kettles or other like culinary vessels, for heating and
boiling water, and is an improvement upon Letters Patent granted to me on the
3rd day of August 1888 and numbered 11247.
Figure 1 of the accompanying drawings, represents partly in elevation, and partly
in vertical section, a lid-less and musical kettle, provided with improvements made
according to one form of my invention. It will be seen that the said kettle, has an
inside and outside spout, the former depending from the front inside top part, and the
latter shaped alike unto a jug or funnel spout, whereby the said outside spout,
constitutes both the means for filling the kettle, and emptying it.
The rear top side or crown of the kettle, has a steam escape tube, whereby steam is
allowed only to escape.
a. is the kettle body part, a² the enclosed top thereof, an outside funnel or jug
shaped spout, and an inside depending spout, with its open lower end 63 directed
to near the bottom a³ of the said kettle, so that should a kettle turn over, or tilt
upon
its side, when the same is partially filled, the water contained within it, is trapped or
prevented from escaping.
The rear crown of the kettle, is provided with a steam escape e, consisting of an
open piece of tubing, with the outside covered or stoppered by a hinge valve c²,
whose joint is at e³, to admit of itself closing, on the pressure of the steam being
less than the weight of the valve.
Thus, on steam accumulating within the inside crown of the vessel, the same is
liberated through the steam escape, which is directed rearwardly through or by
the handle, so that the hand of a person, on removing the kettle when boiling, is
free from the steam issuing therefrom.
Instead of employing a hinge valve c³, as in figure 1, I may employ a ball valve
as in figure 2.
a is the kettle, c the steam escape, c² the valve, and c³ the seat thereof. The outside
end of the said steam escape, is pierced or covered with wire gauze, as shown in end
elevation figure 3.
The said figure 1, is provided at its closed crown, with a whistle, signal, or musical
sounding device d, consisting of a whistle, musical note, or the like d², and a hooded
top do, and is adapted to whistle or give forth a signal or musical note, that the kettle
is boiling.
Thus, on steam accumulating within the inside crown of the vessel, the same
passes through the sounding or musical device d, or through the stean escape c.
When the sounding or musical device is used in conjunction with a steam escape,
then the same gives forth an intermittent or chattering musical sound, in consequence
of the pressure of the accumulated steam being intermittently relieved, by the passing
of it outwardly through the escape.
Figure 4 represents a modified form of my anti-boiling over and musical
kettle.
The depending tube b in figure 1, is now substituted by an inside partition spout

page_text: which is equivalent to a tube spout, and which partition spout is marked 6', with its
lower open end 6 coming within a short distance of the bottom of the kettle, and
with its upper and open end leading to the outside spout b.
The other parts are marked with the same letters of reference as in figure 1.
In figure 4, the valve of the steam escape, is shown open, whilst in figure 1, it is
represented closed..
Figure 5 represents a silent lidless kettle constructed according to my invention.
a is a kettle, a² the closed crown thereof, b the outside spout with an inside spout
directed downwardly from the top which thereby as aforesaid, prevents the kettle from
boiling over, or the water escaping through the upper part of the vessel, should the
same be inadvertently turned over, or upon its side.
c is the steam escape, with its outer open end, covered by wire gauze, to prevent
soot, or other solid matters, from gaining access to the interior of the kettle, through
the said escape.
Figure 6 represents a combined lidless and bronchitis kettle, constructed according
to my invention.
a is the body of the said vessel, a² the enclosed top or crown, having fitted within
it, a socket a³, wherein the end e², of a bronchitis tube length e, takes and fits. The
said length passes through the rear side of handle f, and is fitted with a supplementary
tube length e³.
The kettle is provided on its front top side, with an outer spout b, leading to,
and from an inner spout, alike unto that represented in figure 1, or of that in
figure 4.
:
By centreing the bronchitis tube within. the crown of the vessel, it admits of being
adjusted or turned to any position between the handles.
Figure 7 represents a lidless and silent kettle, made according to another form of
my invention.
f
a is the body of the vessel, 6 the spout, and a hooded steam escape, fitted to the
crown of the vessel. By cowling in the open top or outlet of the steam escape, the
steam issuing therefrom, is spread outwardly, instead of allowing it to impinge on
the hand of a person taking hold of the vessel.
Figure 8 shows a bronchitis kettle, provided with a counterpoise weight, at its rear
top side, to counterbalance the weight of the bronchitis-tube-length.
Usually bronchitis kettles are overbalanced, by the weight of the steam tube, and
the object of this part of my invention, is to remedy this defect, by placing at the
rear of the vessel, a weight slipped on to the handles, or other part.
a is the vessel, 6 the spout, e the bronchitis-tube-length, f the handle of the vessel,
through which the said length passes, h the weight, with recess h², at its inside face,
to admit of it being slipped on the rear base part of the handle, see also figures ý
and 10.
Figure 11 represents a lid kettle, provided with whistle, signal, or other like means,
for indicating the boiling of the water within a vessel.
a is the vessel, the lid thereof, with a whistle, signal, or other musical indicator d,
fitted within its top or dome part, and wherethrough steam issues, and creates e
tension, attention on the boiling of the water within the vessel.
The kettle has an ordinary spout b, with its inner end directed inwardly at b³,
to the bottom of the kettle, for the purpose as aforesaid.
The inwardly directed spout, besides having the advantages as aforesaid, it forms
the only outlet for the egress of water (when full) on vessel turning over.
I wish it to be understood, that I lay no claim to the use of musical or whistling
devices, in connection with kettles, as I am aware that like devices have heretofore
been employed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First Providing kettles, and other like vessels, with inside pouring and trapping
:
:

page_text: spouts 62, substantially as and for the purpose as, described and set forth in
figures 1, 4 and 11.
Secondly -The combination with outside jug or funnel spouts b, as in figures 1, 4,
5, 6, 7 and 8, or an ordinary spout, as in figure 11, of an inside depending outlet or
inlet spout 62, as set forth.
Thirdly Providing lidless, or lid kettles, or like vessels, with an indicating
whistle, signal, or musical sounding device, whereby the boiling of a kettle is
indiented, substantially as described and set forth in figures 1, 4 and 11.
Fourthly Thirdly :-Employing in connection with the top or crown of a lidless,
or lid kettle or like vessel, of a steam escape, egress tube, or device c, substantially
as described and set forth in figures 1, 4, 5, and 7.
Fifthly Fourthly:--Fitting steam escapes, or steam egress devices, with hinged,
or other valves and cowls, for the purpose, substantially as described and set forth in
figures 1, 4 and 7.
Sixthly Fifthly:-The combination with a kettle, or like vessel, of a valved
steam escape c, and a whistle, signal, or musical sounding device d, as set forth.
SeventhlySixthly:-In bronchitis kettles, counterbalancing them, by means
of an added weight, at the rear, or other part opposite to the bronchitis tube,
substantially as set forth.
Eighthly Seventhly:-Fitting the attachment end of bronchitis-tube-lengths, to
kettles, by means of a socket and swivelling joint arrangement, as set forth in
figure 6.
Lastly-The improvement in kettles, as herein described and set forth.
