Improvements in and relating to Means used in Supporting Biscuit
and Glost Ware in Kilns and Ovens.
We, ELIAS LEAK, and HARRY AYNSLEY, Manufacturers, both of Fenton, Stafford-
shire, do hereby declare the nature of our said 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 reference to certain improvements in and relating to means
used in supporting biscuit and glost ware in kilns and ovens, the Invention having
special reference to the "slings used in supporting wash-bowls and the like during
the hardening on process after the pattern has been applied to the ware while in
a biscuit state.
Such slings are used in the manner illustrated in Fig. 1, of the accompanying
drawings, and have hitherto most generally been made by being moulded in a con-
tinuous strip of the rectangular flatsided section shown at, a, Fig. 1, and by such
strip being afterwards cut transversely into portions of about the width represented
at, b. This method of manufacture is disadvantageous in that the transverse cutting
of the strip is very liable to distort the shape of the sling, and, moreover, such flat-
sided shape is detrimental in use as it prevents the firing operation having a proper
effect upon the portion of the ware covered by or in contact with such slings.
It has been sought to remedy this defect by making the slings of the angular
formation represented in the side elevation Fig. 2, and in the under plan view Fig. 3,
such slings being also pressed through a die and cut off into portions of the required
length and being also bent round the finger or any handy appliance; which likewise
involves several operations in the manufacture of each of the slings, and with a con-
sequent liability of distorting the shape of the sling. Such angular shape was of
advantage only in that it reduced the surface of the part upon which the supported
bowl rested, the bottoin part of the sling which rested upon the edge of the supporting
bowl being left flat as theretofore.
The present Invention is designed to obviate the aforesaid disadvantages and to
manufacture such slings entire at one operation integral with lineal or pointed parts
respectively adapted to rest on the supporting bowl and to support the upper
.bowl.
In accordance with the present improvements we make the slings of an arched
saddle like or analogous formation with lineal or pointed edge or intervening parts, 1,
adapted to rest on the lower or supporting bowl, c, and with lineal or pointed
parts, 2, adapted to support the upper bowl, d.
The improved sling is represented in side elevation in Fig. 4 of the accompanying
drawings and in plan view Fig. 5. Fig. 6, represents the same in use in supporting
the bowls Fig. 7, represents a section through a plane indicated by the
line, e, f. Fig. 6, and Fig. 8, represents a section through a plane indicated by the
line, g, h, Fig. 6.
We manufacture the improved slings by moulding them entire at one operation in
suitably formed moulds of the construction illustrated in plan view in, Fig. 9, and in
sectional elevation in Fig. 10, or of any other suitable construction. 3, represents a
mould adapted with a rising false bottom 4, and, 5, represents a reciprocating die. The
mould and the die are, at the parts, 6, 7, respectively adapted to form the parts, 2, 1,
of the sling by compressing the clay or material of which the slings are formed between
them. Upon the die rising the false bottom is by any suitable means caused to
immediately follow it and to raise the moulded sling clear of the mould.

page_text: 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 hereinbefore described improvements in or applicable to the formation
of slings used in supporting wash-bowls or other biscuit and glost ware in kilns
and ovens.
2. The manufacture of such slings by moulding them entire at one operation
integral with lineal or pointed parts adapted to rest on the supporting bowl and to
support a superposed bowl.
3. As a new article of manufacture a moulded sling formed entire at one operation
with lineal or pointed parts adapted to rest on the supporting bowl and to support a
superposed bowl.
