COMPLETE SPECIFICATION.
Improved Domestic Kettle.
RICHARD THOMPSON Drawer-in in a Cotton Mill of 29 Buskmeadow Street
Oswaldtwistle, near Accrington, Lancashire, 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 of an improvement in the construction of domestic kettles,
and has for its object to avoid or do away with certain effects which are caused by
the present defective construction. These effects are frequently the cause of accidents
and annoyance, the first of these effects are the lifting of the lid of the kettle when
boiling water in it, by means of the steam generating a little pressure inside, and
thus allowing the steam to come in contact with the hand of any person who should
try to remove the kettle from the fire, the second effect being the spurting out of
the kettle spout boiling water into the fire, which has the effect of puting out the
fire and causing a great amount of dirt about the fire range, this spurting out is
also caused by the same as the first one, that is a little pressure being generated
inside and lifting the water through the spout into the fire.
This invention consists of providing an escape for the steam as fast as it is
generated so as not to allow of pressure accumulating with such force as to lift up
the lid or force the water out of the spout. This escape is effected by means of a
tube or tubes which form the handle of the kettle and the steam escapes away into
the atmosphere. To prevent the part of the handle that has to be taken hold of
geting too hot and burning the hand, I cover it with asbestos, wood, or any substance
which is a poor conductor of heat and will not burn or break readily.
In order that my said invention may be fully understood and carried into
practical effect I will now proceed to more particularly describe the same and for
that purpose shall refer to the letters of referance marked upon the annexed sheet
of drawings.
Fig. 1 shows an elevation of a domestic kettle with my invention applied in the
handle thereof. Fig. 2 shows a sectional elevation of the same.
The handle as shown at H consists of a tube or tubes which is connected or
attached to the higher part of the kettle body A and is provided with an escape
opening for steam at J. It will be seen that when this kettle is upon a fire boiling
the steam generated will escape into the two pipes or tubes H H and through the
opening J into the atmosphere without geting sufficient pressure inside the kettle
to lift the lid C or force the water out of the spout B. Over the part of the tube H
which has to be taken in the hand, or that part of the tube that forms the handle
for the kettle I provide a covering D of some material which is a very poor

page_text: conductor of heat so as to protect the hand, but I wish it to be understood that I
make no claim for this covering of the handle.
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
First. In domestic kettles the employment or use of a tube or tubes forming the
handle. with an escape opening or openings for steam as and for the purpose
specificied.
Second. The arrangement and combination of parts constituting my improvement
substantially as hereinbefore described.
Dated this Fifteenth day of July 1893.
