Improvements in and in the Manufacture of Sheet Metal Socket
Handles for Saucepans and other Hollow-ware Utensils.
I, JOHN PINSON, of the Firm of Pinson and Evans, of Melbourne Works,
Wolverhampton in the County of Stafford, Wrought Hollowware Manufacturers,
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 the manufacture of sheet metal socket handles,
for fixture to sheet metal saucepans or other sheet metal culinary utensils, by
forming the tubular portion of each handle in one piece of metal with a flap by
which the handle is to be attached to the utensil, and fixing the flap at the required
angle with the tubular portion of the handle in a specially secure manner, whereby
considerable economy in manufacture will be ensured, and neater and lighter
handles produced which will be as strong in use as the less sightly handles now
employed for the purpose.
According to this invention, a metal blank for a handle is cut to a shape which
will not only form the tubular portion of the handle with tongues which will project
from the abutting edges along the underside of the tube, but will form also the flap
of the handle. When the part of the blank to form the tubular portion of the
handle has been bent up to the required tubular shape, the flap remains joined along.
its upper end with the upper side of the tubular portion. When the flap has been bent
back at the proper angle with the tubular portion, it is securely held in such
position by the aid of the tongues which project from the tubular portion of the
handle and which, for such purpose, pass through a hole formed in the flap, and are
clenched back against the inner face of the flap, or preferably within a recess
formed in the inner face of the flap so that the clenched portions of the tongues
will not prevent the flap bedding properly against the surface of the utensil to
which it is to be fixed.
In order that this invention and the method of carrying it out may be clearly
understood, I will now proceed to describe the same with reference to the accom-
panying drawings.
Figure 1 shews a flat metal blank of the shape in outline required for the
formation of the entire handle, including both the tubular portion and the flap. A
curved slit a' is cut in from each side of the smaller end of the blank, as shewn, for
the purpose of forming the shoulders of the intended flap and also the tongues
above referred to, and which are hereinafter more fully described. The blank is
also punched with a hole b through which the tongues are to pass when the blank
has been properly bent to admit thereof, and with holes c by which the flap is to be
riveted to a utensil. The hole d is merely the usual hole for use in hanging up a
utensil.
The blank is next bent in suitable tools, as will be readily understood, into the
shape shewn in plan by Figure 2, in longitudinal section by Figure 3, and in
transverse section on line of Figure 3 by Figure 4, that is to say, the portion A
of the blank which is intended to form the tubular part of the handle is formed into
a trough-shape, and the flap B is bent up at an angle with the portion A, and a
recess or sinking e is formed in the underside of the flap, that is to say, in the side
of the flap which is to come against the utensil when the handle is fixed thereto.
In Figures 2 and 3 the tongues a arcashewn as angular projections on each side,
respectively, from the inner end of the portion A of the blank.

page_text: The blank is next bent into the form shewn in plan by Figure 5, in longitudinal
section by Figure 6, and in transverse section taken on line y y of Figure 6 by
Figure 7, that is to say, with the part A bent up into the finished tubular form
required, and which is preferably oval in section for convenince in handling. In
Figures 5 and 6 the blank is shewn the opposite way up to that in which it is
shewn by Figures 2 and 3, that is to say, with the part which is to form the under-
side of the handle downwards. In forming the blank to the shape shewn by
Figures 5 and 6 the tongues a a are brought together, as shewn more especially by
broken lines Figure 5, and their ends are then in such position in relation to the
hole through the flap that if they are bent slightly inwards at their points they
will enter and pass through such hole as the flap is bent further back.
The next process is to slightly bend in the points of the tongues and bend back
the end of the flap as far as possible against the inner end of the tubular portion,
with the tongues projecting through the hole bin the flap; and the flap is then held
upon a die, suitably recessed to receive the embossed portion occasioned in forming
the recess e, and the tongues are clenched down against the inner face of the recess,
as shewn by Figures 8 and 9 which are, respectively, a longitudinal section and a
view of the inner end of the finished handle. The tool on which the flap is held
for this purpose is, of course, cambered or curved on its face to give the flap the
curved shape which will make it fit against the utensil to which it is to be fixed.
It will be seen that the upper end of the flap remains joined as a continuous
piece of metal with the upper part or back of the tubular portion of the handle,
being simply bent at an angle therewith; and that the underside of the handle is
securely connected with the flap by means of the tongues a which project from the
tubular portion immediately on each side of the slit or joint along the underside of
the handle.
When a handle constructed as above described is fixed to a sheet metal sauce-
pan or other utensil, and the utensil is subsequently coated with tin, as is usual, the
molten metal thoroughly fills up any crevices in the joint or connection between the
tubular portion of the handle and the flap, and between the entire handle and
the utensil, and the tongues are consequently firmly soldered or cemented in place
with the result that the handle, though light and cheap in manufacture, is very
strong.
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. The improved manufacture of sheet metal socket handles for saucepans and
other hollowware utensils, which consists in forming the tubular portion and flap of
each handle in one piece of sheet metal with tongues projecting at the inner end of
the underside of the tubular portion on opposite sides of the slit or joint therealong,
passing such tongues through an opening formed in the flap and clenching them
back against the inner face of the Hap, or against the inner face of a recess formed
in the flap, substantially as described.
2. Sheet metal socket handles for saucepans and other hollowware utensils, each
having a flap formed in one piece of metal with the tubular portion and tongues
projecting from the underside of suck tubular portion passing through the flap and
clenched back against the inner face thereof or against the inner face of a recess
sunk therein, substantially as described.
3. Sheet metal socket handles for saucepans and other hollowware utensils made
substantially as described and shewn by the drawings herewith.
