I, WILLIAM TELFER, Manager to Messieurs Walter Neilson & Co, Ironfounders,
of Park Foundry, Kinning Park, in the County of Renfrew, do hereby declare the
nature of my said Invention for "AN IMPROVED MODE AND MEANS OF SECURING
HANDLES IN SAUCE-PANS AND OTHER HOLLOW-WARE;" to be as follows:-
The object of my Invention is to enable the hollow form of sheet-metal handles
to be more easily and quickly secured into the sockets cast for them in sauce-pans,
goblets and other such hollow-ware, than they have been heretofore.
And the nature and novelty of the improvements consist as follows-in casting
two small projections exactly opposite each other on the inside and near the centro
of the conical sockets cast on the pans or vessels into which the handles have to be
secured; these projections would preferably be square or at least have a flat side on
the inner face, which would be at a uniform distance from the bottom of the socket,
and project rather higher than the thickness of the sheet-metal handle to be secured
by them.
188-1
The handles constructed first all as described in the Specification of my Patent
N° 6575 April 19 would then one at a time have their inner ends slipped over a
round punching die, with the small square hole in it at the proper distance,
regulated by a screw or other stop against which the end of the handle would be
pushed, when a screw or lever punch erected over the hole in the die would be
brought down to punch the hole in the upper side of the handle; but the punch
would also be formed with a round edged compressing feather behind it, which
after the hole is punched, would press the thin sheet-metal between the hole and
the end of the handle down into a corresponding groove in the die, and form this
into a sheet hollow longitudinal rib. Then on the punch and presser being lifted,
the workman would turn the handle half round on its internal round die, until a
regulating or setting spring pin prong fitted on the underside, would slip up into
the punched hole, be turned down and so set the handle truly opposite, so that when
the punch is again brought down, it would punch the second hole and form a
Price-8d1

of the handle so formed would then be ready for being driven tight into the socket,
the bollow grooves slipping over the projections in the socket until this came
opposite the holes punched for them in the handle. A long steel spindle is then
inserted down into the hollow handle from its outer wide end, formed with two
small eccentric or curved cam expanders, one on each side of its inner end just
below the projection, and which on being turned by a cross lever or hand wheel on
the outer end of the spindle, forces out the hollow grooves of the handle into their
former conical shape to fill the socket perfectly tight below the retaining projections,
and thus secure the handle so rigidly to the socket that it cannot be removed.

I, WILLIAM TELFER of Park Foundry, Kinning Park in the County of Renfrew,
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:—
The object of my invention is to enable the hollow form of sheet metal handles
to be easily and quickly secured into the sockets cast for them in saucepans,
goblets, and other articles of hollow-ware. To that end I cast two or more small
horns or projections diametrically opposite each other on the inside and near the
centre of the conical socket which is cast on the pan or vessel into which the handle
is to be secured and in the tubular handle I punch two holes corresponding to the
horns in the socket and form grooves or depressions in the line of the holes to
permit of the insertion of the handle the depressions being afterwards pressed
out by a suitable tool to secure the handle and prevent its withdrawal from the
socket.
My invention is illustrated by the accompanying drawings in which figure 1, is
a sectional plan of a goblet showing the horns or projections formed in the socket
for the handle. Figure 2 is a longitudinal section and figure 3 is an end elevation
of the pot handle and figures 4 and 5 are end and side elevations of the tool which
I employ by preference, for pressing out the depressions formed in the end of the
handle. The two (or more) horns or projections a, are formed in the socket A, at
an approximately uniform distance from the bottom of the socket and project
rather higher than the thickness of the sheet metal handle to be secured by them
the horns being rectangular in plan and their inner faces being flat in order the
better to secure the handle.
The pot handle B, is by preference constructed in the manner described in the
specification of my Patent N° 6575 of 1884 and the holes b, and grooves or
depressions c, are formed in the flat piece of sheet metal from which the handle is
made, by employing suitable punches and dies; or they may be formed by slipping
the end of the handle over a round punching die with a small square hole in it at
the proper distance which may be regulated by a screw or other stop against which
the end of the handle may be pushed, when a screw or lever punch crected over the
hole in the die would be brought down to punch the hole in the upper side of the
handle. The punch is also formed with a rib or compressing feather behind it,
which after the hole is punched presses the thin sheet-metal between the hole and
the end of the handle down into a corresponding groove in the die to form the
groove or depression in the end of the handle. On the punch and presser being
lifted the handle may be turned half round on its internal round die, until a
regulating spring pin or prong fitted on the under side slips up into the punched
hole and sets the handle truly opposite, so that when the punch is again brought
down it punches the second hole and forms a second hollow groove in the end of
the handle exactly opposite the first. The end of the handle B, when formed as

page_text: shown in figures 2, and 3, is driven tightly into the socket A,.the hollow groove c,
slipping over the horns or projections a, in the socket until the horns are opposite
the holes punched for them in the handle. A tool of the kind shown in figures 4,
and 5, which consists of a lever spindle D, formed with two small eccentrics or
curved cams d, is then inserted into the handle B, with the cam pieces below the
horns a, and is slowly turned by means of a cross lever D¹, until the cam pieces d,
press out the grooves or depressions of the handle to fill the socket perfectly tight
below the retaining horns or projections and thus secure the handle so rigidly to
the socket that it cannot be removed.
This mode of securing pot handles into their sockets has the advantage over the
usual method, of saving time and labour and the breakage which occurs in rivetting
on the handles, while the pots or pans may be stored or shipped apart from their
handles which may be afterwards fitted in their sockets; and the handles may be
suitably varnished by dipping and be dried at high temperatures to which it is not
advisable to expose the hollow ware after tinning.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
(1) The mode and means of securing handles in hollow ware by forming horns
or projections within the sockets, punching holes and grooves in the handle to fit
over such horns and subsequently pressing out the grooves below said horns
substantially as herein described.
(2) As an improved article of manufacture a tubular handle for saucepans or
other hollow ware, formed with holes and grooves or depressions as and for the
purpose set forth.
(3) As an improved article of manufacture a sauce-pan, pot, or similar article of
hollow ware formed with a handle socket having internally projecting horns
adapted to secure the handle in its socket substantially as described.
(4) As means for securing the handles of saucepans and other hollow ware a tool
having cams or eccentrics d; operating as set forth.
