SPECIFICATION.
Improvements in Securing Handles to Sauce-pans, Stew-pans, and
certain other Cooking Utensils.
We, EDWIN CHESSHIRE, of Newhall Street, in the City of Birmingham, and
JOHN HENRY CHESSHIRE, of Old Meeting Street, West Bromwich, Staffordshire,
trading together as Izons & Company, Ironfounders and Hollow-ware Manu-
facturers, and HIRAM FRENCH, of 100, Littleton Street, West Bromwich,
aforesaid, Foreman, 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 consists of the herein-described improvements on the method
described in the Specification of Letters Patent No. 21661 of A.D. 1891 of
securing tubular metal handles in the cast sockets of sauce-pans, stew-pans and
other cooking utensils which have tubular handles and cast metal sockets for the
same. In the Specification of the said prior patent the tubular handle which is
circular is described as being made with one or more longitudinal indented grooves
at that end which fits in the socket which latter has one or more inwardly
projecting pegs or pips which take into the indented grooves in the handle when
the latter is placed in the socket. After the handle has been inserted in the socket
it is secured by pressing the parts of the groove behind the pips or pegs into a
cylindrical shape by rotating a tool which is inserted at the open end of the handle.
By our present invention we are enabled to dispense with the indented longitudinal
groove or grooves in the handle and with the pips or pegs in the socket and we fix
the handle more securely than heretofore. We employ the same kind of tool as
described in the Specification of the prior Patent above referred to and it is to be
understood that this tool herein referred to and shewn upon our drawing forms no
part of this present invention.
We will describe our invention by referring to the accompanying drawing on
which
Fig. 1 is a sectional elevation and Fig. 2 is a front view and Fig. 3 is a cross
section of the metal socket formed according to our present invention and
Fig. 4 is an end view and side elevation of the tubular sheet metal handle for
fitting in the same;
Fig. 5 is a longitudinal section of the handle fixed in the socket ;
Fig. 6 is a cross section of the same on line X X of Fig. 5 and
Fig. 7 is a cross section of the same on line Y Y of Fig. 5 ;
Fig. 8 illustrates the tool which we employ for fixing the handle shewn by Fig. 4
into the socket shewn by Fig. 1;
Fig. 9 is a longitudinal section of the handle fixed in the socket according to a
modification of this invention and
Fig. 10 shews the formation of the tool for fixing the handle in the socket as
shewn by Fig. 9.
Fig. 11 shews a further modification of our invention and
Fig. 12 shews a further modification of the same.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
In carrying out our present invention that end a of the tubular handle A which
fits in the cast socket B of the sauce-pan or other cooking utensil is made oval as
shewn in Fig. 4 the hole 6 in the socket B being made of corresponding shape as
shewn in Fig. 2. The shorter axis of the oval is by preference vertical passing
through the usual open joint of the tubular handle. To make the end à of the
handle oval it is only necessary to take an ordinary round handle and slightly

page_text: flatten it between a pair of dies. In the oval hole 6¹ in the socket B (which hole
is made slightly taper corresponding with the handle) we cast a circular groove c
which is concentric with the axis of the handle and is of about the same diameter
as the longer axis of the oval hole. This groove is clearly shewn in Figs. 1 and 3.
To fix the handle A in the socket B the smaller end a of the handle is inserted in
the socket as far as it will go; the tool D Fig. 8 is then passed into the handle as
in the prior Patent No. 21661 of A.D. 1891 above referred to until the extreme
end d of the tool comes in contact with the bottom of the socket. The tool D
is then by its handle d¹ turned round so that the bits or projections d³ d' thereon
will force out into a cylindrical form those portions of the handle which are near
the groove c so that those portions will be pressed into and fill the groove as shewn
in Figs. 5 and 7 thus securely fixing the handle in the socket. It will be under-
stood that the bits d' d' of the tool D have to be made of just the proper size to
fit into the oval end a of the handle. By making the tubular handle A oval where
it fits in the socket B and fixing it therein as above described the handle cannot
possibly become loose or be removed from the socket.
It is to be understood that we do not confine ourselves to employing only one
circular groove c as above described and shewn in Figs. 1 and 5 as we may use two
of these circular grooves as shewn in Fig. 9 where the said grooves are respectively
marked c c¹ the groove c¹ being placed nearly at the bottom of the hole in the
socket. In this case it will be understood that the tool D must have
projections d d as shewn in Fig. 10 corresponding with the groove c' so that when
the tool D is inserted in the handle and turned as above described these por-
tions dod will bulge out the end of the handle into the groove c' simultaneously
when the bits or projections d³ d bulge out the other portions of the handle into
the groove c.
In further modifications of our invention shewn by Figs. 11 and 12 respectively
the groove c (Fig. 11) is or the grooves c c (Fig. 12) are made semi-circular and
thus extend only half-way round the socket instead of being made circular and
extending all round the socket as in the examples above described with reference
to Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10. In these cases the bit or projection d' or
bits or projections d' de on the tool D have to be dispensed with.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The improvements in securing tubular metal handles in the cast sockets of
sauce-pans, stew-pans and other cooking utensils hereinbefore described and
illustrated in the accompanying drawing consisting in making the handle hole in
the socket and the end of the handle which fits therein oval in cross section in
combination with a circular or semi-circular groove or grooves such as c c in the
socket and then, after the handle has been pushed home into the said socket,
forcing out by a tool such as D a portion or portions of the handle into the said
groove or grooves in the socket so that the handle and the socket will be engaged
together in the manner substantially as herein before set forth.
2. The manufacture and sale of sauce-pans, stew-pans and other cooking utensils
in which the tubular metal handles are secured in the cast sockets in the manner
substantially as hereinbefore described and illustrated by the accompanying
drawing.
Dated this 6th day of October 1893.
