COMPLETE SPECIFICATION.
Improvements in the Necks of Wrought Metal Kettles, and in the
Manufacture of the same.
I, CHARLES HENRY HILL, of the Firm of Francis Hill, of Belmont Works,
Belmont Row, Birmingham, in the County of Warwick, Manufacturer, do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
My invention has for its object improvements in the necks of wrought metal
kettles and in the manufacture of the same which I make stiffer and more
substantial and in every respect superior and better able to withstand the wear
from frequently replacing of the lid of the kettle upon the neck. According to
my present invention I add to the top of the neck either internally or externally or
partly externally and partly internally a stiffening ring or rings of cast iron or
metal which may be either annealed or not according to the mode adopted for
securing the same in position and which I shall explain hereafter more fully.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
and also a single sheet upon which I have illustrated various modes of carrying
the same into practice, but it must be understood that the various shapes shown
are only for the purpose of example and may be varied as to design or shape.
Figure 1 is a part section and part side elevation of the neck A of a kettle
made according to my invention.
Figure 2 is a broken off plan of Figure 1.
Figure 3 is a section of the stiffener B showing its form before it is secured to
the neck A of the kettle.
Figure 4 is a cross section of the stiffener B made according to a modification
with a wrought iron or steel hoop E cast in the ring B.
Figure 5 is a perspective view of the ring E before it is applied to the mould
in which B is cast.
Figure 6 shows a modification of B which in this case bas a recess formed on
the top to receive the lid of a kettle, the lid in this case being flangeless.
Figure 7 is a modification of the foregoing in which the stiffening ring B is
covered by the neck B of the kettle on its outside face.
Figure 8 is a modification of Figure 7.
Figure 9 is another modification of Figure 7 showing the stiffening neck B
outside the neck A.
Figure 10 is a broken off plan of the neck A showing a modification of the
mode of flanging by short ears as the principal of which is generally applicable to
the rings B as the turn flanges or lips may in most cases be made with short lips
instead of a continuous flange.
The necks of kettles are now made when the lid enters and rests by turning the
edge over and by sometimes wiring it as well known. At this portion of a kettle
the wear and strain is considerable and when this portion is worn out the kettle is
useless. Now according to my invention kettles are strengthened at the mouth
and formed at the mouth when the lid enters, and rests, by a supplemental ring of
metal such as cast iron, cast brass, wrought iron or steel or other metal which is

page_text: sometimes annealed to allow it to bend and sometimes it is fastened in other ways
without being annealed as will be hereafter explained.
According to one mode I make a cast metal ring as seen in section at Figure 3
and having rebute b¹ and a projection 62. This ring is placed in the hole of the
neck A and forms a binding to the edge of A being secured to A by turning over
the edge 62 as seen at Figure 1. It will thus be seen that the raw edge of A is
entirely covered and protected and that the substantial casting B takes all the
wear and by which I obtain a stiff and firin and lasting base for the lid of the
kettle or similar vessel.
The turn over lip 2 may however he provided for by forming a wrought metal
ring of say such material as hoop iron or steel as seen at Fig. 5 which is then
placed in the mould when the cast metal is run around it as seen in section at
Fig. 4. The lower portion is then bent up instead of 2 when the effect is
similar.
Sometimes I make the lids of kettles without a ring to enter the kettle in
which case I form the stiffening ring B with an internal projecting flange b* so
as to leave the rebute 3 into which the lid fits as seen at Fig. 6 but in this view
is shown before being bent over but otherwise when finished it would appear as
seen at Fig. 1.
The same stiffening effect may be produced by a partially covered ring B as
shown at Fig. 7 and 8. In Figure the neck A of wrought metal forms the
outside bead a¹ and the hole a² for the lid and is worked round at a³ to entrance B
while at Fig. 8 it is held in position by rivits R which may either pass through as
those seen or they may be cast as projections on B as seen at Fig. 9 only that at
Fig. 9. they are internal and the ring B is exterual, though the principle of
stiffening is the same in both examples.
At Fig. 10 I have shown the neck A. which may be made from any wrought
metal with ears a, a, a of which these may be any convenient number to turn over
and embrace the stiffening ring and generally, as I have before said ears may be
formed on the stiffeners B instead of continuous flanges for turning over, the
principle of stiffening being substantially the same.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is.
First. The improvements in the necks of wrought metal kettles and the like
consisting of the strengthening ring B made from cast metal annealed or its
equivalent, placed over opening of the neck and bent round at 62 to embrace the
neck A substantially such as explained and illustrated by Figs. 1, 2 and 3 upon
the drawings.
Second. In improvements in the necks of kettles and the like, making the
strengthening ring B with a wrought metal hoop E as and for the purpose herein
set forth and shown by Figs. 4 and 5.
Third. The modification shown by Fig. 6 in which an internal flange is
provided in one piece with the strengthening ring B as herein set forth.
Fourth. The particular mode of making and mounting the strengthening ring B
such as illustrated by Figs. 7, 8, & 9 and substantially as herein set forth.
Fifth. The improvements in the necks of kettles and the like as illustrated on
the drawings Figs. 1 to 10 inclusive and as set forth therein.
Dated this 11th day of November 1896.
