Improvements in the Manufacture of Handles for Pottery Ware.
We JOSEPH GOSLING and JAMES FREDERICK COATES, of Hanover Iron
Works, Hanover Street, Burslem, Staffordshire, Potters' Engineers do hereby
declare the nature of this invention to be as follows:-
The improvements relate to the manufacture of handles for pottery ware and
have for object the moulding of the same by means of a die and press instead of by
means of plaster casts as obtains at present.
To accomplish this and to effect our improvements, we construct a die primarily
in two halves, an upper and lower, with suitably formed recesses for moulding the
shape of the handle, but the lower half is also constructed with a shaped piston
following the contour of the handle, which piston is capable of ejecting the
moulded handle from the lower half of the die by being operated by a foot
treadle.
Variations in the pattern of the dic, and the press mechanism for actuating the
same may be made without departing from the peculiar character of the
invention.

page_text: Fig. 3 shows a plan view of a portion of such apparatus, and
Fig. 4 a perspective view of the shaped piston for ejecting the moulded
handles.
The same letters indicate corresponding parts wherever they occur.
a is the upper half of the die, either resting in, formed with, or attached to any
suitable support b, and a' is the lower half of the die also either resting in, formed
with, or attached to any suitable support 61; such supports being part of an
ordinary or other die press, the mechanism of which is not shown as such will be
well understood.
с
The upper half of the die, as at a, is recessed to the requisite depth, such recess
or recesses being also curved longitudinally to the figure of the handle to be
moulded; while the lower half of the die, as at a', is constructed with a corre-
spondingly curved opening, or openings, passing completely through it. The
curved piston e is arranged to slide in this opening, or openings, being properly
shaped and fitted for the purpose, and may rest on, form part of, or be attached to
the table c' at the end of the rod d, or even may be attached directly to such rod,
or otherwise. The uppermost face of the curved piston c is also formed with a
recess or recesses therein corresponding with those marked a' in the upper part of
the die.
The mode of operation is as follows:-
When the piston c and die a¹ occupy the relative positions shown in Fig. 2, and
when the upper portion of the die is raised clear of the lower by means of the
ordinary press mechanism, the apparatus is ready to receive the necessary supply
of clay or other material. This being accomplished, the two halves of the die are
pressed together, and the moulding of the handle is complete. The upper part of
the die is then again raised clear of the lower, and the shaped piston c is elevated
by a foot treadle, or by other means, for communicating motion to the rod d, when
the moulded handle can readily be removed from the die on account of its elevated
position on the projecting curved piston.
Variations in the pattern of the die, and the press mechanism for actuating
the same, may be made without departing from the peculiar character of the
invention.
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:-
In apparatus suitable for moulding handles for pottery ware, a die press
combined with a piston shaped to the requisite pattern and so arranged as to
enable it to pass through the lower half of the die and capable of sliding up and
down therein, and at the same time forming the support for the material composing
the handle both before and after moulding the same, for the purpose and in manner
substantially as herein shown and described.
