"
For this purpose I form or cast on the side of the vessel a dovetail socket, that
is to say, a socket, the internal diameter of which gradually increases from the
mouth or external orifice inwards. Upon one side of the bore of this socket, I cast
a solid wedge with its point nearest to the mouth or external orifice of the socket.
The tubular handle, which may either be tapering or not, is made with a butt
joint, and of such a size at one end as will just enter the mouth or external orifice
of the socket. The handle is inserted into the mouth or external orifice of the
socket with its butt joint in contact with the point of the wedge, and is then
driven into the socket by a mallet. The wedge enters tia butt joint and opens it
out more and more as the handle is driven into the socket, thus making the handle
gradually increase in diameter as it enters the socket, so that when it is driven
home every part of it inside the socket is larger than the orifice by which it
entered, and it is firmly fastened without any other operation than merely driving
it in. In another modification of my Invention I cast the socket of the same form,
but instead of casting a wedge upon one side of the bore of this socket, I cast a
wedge shaped pin in the centre of the base of this socket, which, instead of entering
the butt joint of the handle, enters the tube of the handle itself and opens it out.
In a third modification of my Invention I cast the socket of the same form, as
herein before described, but instead of the wedge or the pin, I enclose a loose ball or
marble of metal or other hard material in the core upon which the bore of the
socket is cast, such ball or marble being of greater diameter than the mouth or
external orifice of the socket. This ball or marble enters the tube of the handle as
it is being driven into the socket and opens it out.

"IMPROVEMENTS
IN SECURING TUBULAR HANDLES TO CULINARY AND OTHER HOLLOW-WARE
VESSELS."
This Invention relates to improved means for securely fixing tubular metallic
handles to cast iron sauce pans and other similar hollow-ware vessels without
rivetting, and without weakening either the vessel or the handle by drilling,
punching, or otherwise forming holes therein.
For this purpose I form or cast on the side of the vessel a dovetail socket, as
shown at a, a, on Fig. 1 of the annexed Drawing, which represents in longitudinal
and transverse section a small portion of the side of a hollow-vessel with the socket
cast therewith.
The socket a, a, is so formed that its internal diameter increases gradually from
the mouth or external orifice b, b, inwards. Upon one side of the interior of this
socket I cast a solid wedge c, c, with its point nearest to the mouth or external
orifice b, b, of the socket a, a.
The tubular handle d, d, (Fig. 2) which may be either tapering or not, is made
from sheet metal in the usual manner with a butt joint, as at e, e, and of such a
size as will just enter the mouth or external orifice b, b, of the socket a, a
The handle d, d, is inserted into the orifice of the socket a, a, with the end of its
butt joint e, e, in contact with the point of the wedge c, c, and it is then driven
driven into the socket by a mallet.
The wedge c, c, enters the butt joint e, e, and opens it out more and more as the
handle is driven into the socket, thus causing the handle to gradually increase in
diameter as it enters the socket, so that when it is driven home, as shown at Fig. 3,
every part thereof inside the socket a, a, is larger in diameter than the orifice b, b,
by which it entered, and it becomes firmly fastened into the socket without any
other operation than merely driving it in. Fig. 4 is a plan or top view showing
the external appearance of the socket and handle.
In a modification of my Invention, shown in section at Fig. 5, I cast the
socket a, a, of the same form both inside and outside as before, but instead of
casting a wedge upon one side of the bore of the socket, I cast a conical pin or
peg ff, in the centre of the base of the socket, which, instead of entering the butt
joint of the handle, enters the end of the tube itself and opens it out.
In a further modification of my Invention illustrated by Fig. 6, I cast the
socket a, a, of the same form as before, but instead of the wedge c, c, or the pin f, f,
I enclose a loose ball or sphere of metal or other hard material in the core upon
which the bore of the socket a, a, is cast, such ball or sphere being of greater
diameter than the mouth or external orifice b, b, of the socket.
This ball or sphere g, g, enters the end of the tube of the handle as it is being
driven into the socket, and opens it out in the same manner as the pin or peg.
Having now described the nature and object of my said Invention, together
with the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I claim as my Invention,―
First. The socket a, a, cast or formed on the side of the vessel having its
internal diameter conical, and gradually increasing from the mouth inwards, and
provided with a fixed wedge or a conical pin or peg, or a loose ball for the purpose
specified.

page_text: Secondly. The combination with such socket so formed and provided of a tubular
metal handle made with a butt joint, and expanded and fixed by being driven into
the socket, as hereinbefore described.
In witness whereof, I, the said Charles Ezard, have hereunto set my hand
and seal, this Sixth day of April, in the year of our Lord One thousand
eight hundred and eighty two.
