PROVISIONAL SPECIFICATION.
Knobs for the Lids of Tea Kettles, Tea and Coffee Pots, and the like.
I, THOMAS STOKOE LYON, Metal Worker, Ivy Holme, Haydon's Road, South
Wimbledon, Surrey, do hereby declare the nature of this invention to be as
follows:-
In carrying out my invention I provide a blank of any suitable metal or
material having a groove formed in same, and by placing two of these blanks
together with the hollows of grooves facing each other the grooves form centre of
stem and bottom end of shank of knob; and by bending the two upper ends of
blanks at right angles with the grooves the head of shank is formed to take the top
of knob which top of knob is made by clenching or closing a disc around the edge
and under head of shank.

COMPLETE SPECIFICATION.
Knobs for the Lids of Tea Kettles, Tea and Coffee Pots, and the like.
I, THOMAS STOKOE LYON, of Ivy Holme, Haydons Road, South Wimbledon
in the County of Surrey, Metal Worker, 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 an improved manufacture of knobs for the lids of tea
kettles, tea and coffee pots, and the like whereby the stems or shanks of the knobs
are made out of one piece of sheet metal in a more economical manner than
hitherto.
In order to enable the invention to be clearly understood I will describe how it
can be carried into practice by reference to the accompanying drawing.
In manufacturing my improved knobs I first stamp or otherwise form a blank of
the shape shewn in plan at Figure 1 and in edge view at Figure 2 of the drawing
out of suitable sheet metal. I then by stamping form the centre part with a recess
and bend down the ends at right angles, as clearly shewn in the side view at
Figure 3, and the underside and end views at Figures 4 and 5 respectively.
a represents the recessed part, and b, b the turned down ends; the blank thus
recessed and with its ends turned down is then doubled at its centre b', the edges
or corners c being brought together into the position shewn in Figures 6 and 7
which are elevations at right angles to one another, the end portions 6, b being
brought together so as to form a circular head to the stem or shank c', as shewn in
plan at Figure 8, such head being adapted to receive the cap or top d of the knob of
the usual form, as shewn in section at Figure 9, the said top d of the knob being
clinched or closed around the edge and under the head of the already formed stem
or shank c', as shewn in sectional elevation at Figure 10. Figure 11 is a front
elevation of the complete knob, and Figure 12 an underside view of the same.
In cases where the knob has a separate piece of material (such as ivory, bone or
the like) inserted in the top or head thereof to serve as a label or for any other
purpose, the top of the knob is formed in the shape of a ring f, as shewn at
Figures 13 and 14 which are respectively a sectional elevation and a plan of a knob in

page_text: which e represents a flanged disc which is inserted in the ring-shaped top f, the
said ring being turned over the flange of the disc e and under the head of the
shank e¹.
In the drawing I have shewn a form of blank suitable for making knobs round or
circular in plan, but it will be obvious that any other suitable shape of knob may
be formed by modifying the shape of the blank.
When the knobs are made from tin or terne plate, I can make my blanks from
scrap thereby utilizing what is otherwise generally waste material.
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 :-
1. Forming the shanks or stems of knobs for the lids of tea kettles, tea and
coffee pots, and the like from blanks of sheet metal in the manner substantially as
hereinbefore described and illustrated in the accompanying drawing.
2. A knob for a lid for a tea kettle or like article having a stem or shank
formed from a blank of a shape such as that shewn in Figure 1 of the drawing and
having the cap or top clinched or closed over the head of the stem or blank,
substantially as hereinbefore described and illustrated in the several figures of the
accompanying drawing.
3. The manufacture and use of the improved knobs for lids of tea kettles and like
articles hereinbefore described and illustrated in the accompanying drawing.
