PROVISIONAL SPECIFICATION.
Improved Construction or Forms of "Thimble Pins" used for
Supporting Pottery-ware whilst being Fired.
JOHN ALFRED EDWARDS, ARTHUR JAMES BAILEY EDWARDS, and
WALTER PROCTER EDWARDS King Street, Fenton, Staffordshire, Earthen-
ware Manufacturers, do hereby declare the nature of this invention to be as
follows:-
This our invention has reference to "thimble pins," and the object of our said
invention is to construct the internal and external tapering portion of such "thimble
pins" of such a shape or configuration that when in use for supporting pottery-ware
whilst being fired, we considerably lessen the liability of adhesion of such "thimble
pins" to one another.
As is well known "thimble pins" as at present made, when used for supporting
pottery-ware whilst being fired are superimposed and fit one into the other,
the glaze from the ware often causing the "thimble-pins" to stick or adhere firmly
together.
To carry our said invention into practice we form by means of a metal die or
dies attached to a suitable machine, clay "thimble-pins" having a conical hole or
aperture formed in the larger end, and the tapering portion of a square, rectangular,
triangular or polygonal cross-section, or the outside tapering portion of the
"thimble-pin" may be made plain and conical as at present, and the aperture or
hole formed in the larger end of a square, rectangular triangular or polygonal
shape, or the thimble pins may be made with ribs on the inner surface of the
tapering holes, and the outer conical surface left plain, or ribs may be formed on
the outer conical surface of the "thimble pins," and the tapering aperture left plain,
so that when the tapering portion of the "thimble-pins" are placed in the aperture
formed in the larger end of each other, the said tapering portions do not fit closely
all round, but only touch or bind against the internal peripheries of the apertures
at three or more places according to the shape of the "thimble pin" used, thus it
will be understood that when the article supported by the said "improved thimble
pins are being fired, the evaporation of the glaze will not cause the "thimble
pins" to fasten or stick together by reason of the reduced surface of contact.

Improved Construction or Forms of "Thimble Pins" used for
Supporting Pottery-ware whilst being Fired.
JOHN ALFRED EDWARDS, ARTHUR JAMES BAILEY EDWARDS, and
WALTER PROCTER EDWARDS, King Street, Fenton, Staffordshire, Earthen-
ware Manufacturers, 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 our invention has reference to "thimble pins" used for supporting pottery
ware whilst being fired, and the object of our said invention is to construct the
internal and external tapering portions of thimble pins of such a shape or con-
figuration that when in use for supporting pottery ware whilst being fired, we

page_text: As is well known thimble pins as at present made when used for supporting pottery
ware whilst being fired are superimposed and fit one into the other, the glaze from
the ware often causing such thimble pins to stick or adhere firmly together.
To carry our said invention into practice we form by means of a metallic die or
dies attached to a suitable machine, clay thimble pins of any convenient size having
a conical hole or aperture formed in the larger end, and the tapering portion of a
square, rectangular, triangular, or polygonal cross section, or the outside tapering
portion of the thimble pin may be made plain and conical as at present, and the
tapering aperture or hole formed in the larger end of a square, rectangular,
triangular or polygonal shape, or the thimble pins may be made with longitudinal
ribs or ridges on the periphery or surface of the tapering aperture and the outer
conical surface plain, or longitudinal ribs or ridges may be formed on the outer
conical surface of the thimble pins, and the tapering aperture left plain, so that
when the tapering portion of the thimble pins are placed in the aperture formed in
the larger end of each other, the said tapering portions do not fit closely all round,
but only touch or bind against the internal peripheries of the apertures at three or
more places according to the shape of the thimble pins used, thus it will be under-
stood that when earthenware articles supported by the said improved thimble pins
are being fired, the liability of adhesion of such thimble pirs to one another by the
evaporated glaze will be considerably lessened by reason of the reduced area of
contact.
In order that our said invention may be more readily understood and explained
in detail we have hereunto annexed a sheet of drawings on which letters of reference
are marked on corresponding parts on all the figs. alike.
DESCRIPTION OF DRAWINGS.
Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 are side elevations of different forms of
thimble pins made according to our invention.
Figs. 1, 2, 3, 4, 5, 6ª, 74, 84, 94, 104 and 11* are sectional plans taken
through the line x-x on Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11.
Fig. 12 is a side elevation shewing the way thimble pins fit one into the other
whilst in use for supporting pottery ware.
The above figs. being drawn about full size.
In these figs, a indicates the external parts or portions of our improved form of
thimble pins which fit or bear against the internal tapering surface of each other,
when such thimble pins are superimposed or fitted one into the other as shewn at
Fig. 12. In the section plan illustrated at Fig. 94 it will be seen that longitudinal
ribs or ridges b are shewn formed on the inner periphery or surface of the tapering
aperture of such thimble pins, and in Figs. 11, 11A and 12, ribs or ridges bare
formed on the outer tapering portion of the thimble pin, and we find that by using
our improved forms of thimble pins for supporting pottery ware whilst being fired
that we considerably lessen the liability of adhesion of such thimble pins to one
another by reason of the reduced area of contact as hereinbefore mentioned.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is ;-
1st. The construction of thimble pins for use in supporting pottery ware whilst
being fired of any convenient size having a conical hole or aperture formed therein,
and the outside tapering portion of a square, rectangular, triangular or polygonal
cross section, for the purpose of lessening the liability of adhesion of such thimble
pins to one another when in use, by reason of the reduced area of contact as herein
substantially described set forth and illustrated at Figs. 1, 1ª, 2, 2^, 3, 3, 4, 4^,
5, 5, 6, 6, 7, 7, 8, 8, 10 and 104, on the drawings hereunto annexed.
2ndly. The construction of thimble pins for use in supporting pottery ware
whilst being fired of any convenient size having the outside tapering portion plain and
conical and the hole or aperture of a square, rectangular, triangular or polygonal

page_text: shape for the purpose of lessening the liability of adhesion of such thimble pins to
one another when in use by reason of the reduced area of contact as herein
substantially described and set forth.
3rdly. The construction of thimble pins for use in supporting earthenware whilst
being fired of any convenient size, having the outside conical surface plain and
three or more longitudinal ribs or ridges 6 formed on the periphery or surface of
the tapering apertures for the purpose of lessening the liability of adhesion of such.
thimble pins to one another when in use by reason of the reduced area of contact
as herein substantially described set forth and fully illustrated at Figs. 9 and 9ª, on
the drawings hereunto annexed.
4thly. The construction of thimble pins for use in supporting pottery ware
whilst being fired of any convenient size, having three or more longitudinal ribs or
ridges 6 formed on the outer conical surface of such thimble pins, and the tapering
surface or periphery of the aperture in such thimble pins plain, for the purpose of
lessening the liability of adhesion of such thimble pins to one another when in use
by reason of the reduced area of contact as herein substantially described set forth
and illustrated at Figs. 11, 11 and 12 on the drawings hereunto annexed.
