page_text: LETTERS PATENT to Jacob Furnival, of Leamington, in the County of.
Warwick, Thomas Furnival, of Coleridge, John Derbyshire, of Longton,
and Francis Joseph Emery, of Burslem, all in the County of Stafford,
for the Invention of "IMPROVEMENTS IN APPARATUS FOR SUPPORTING ARTICLES
OF CHINA AND EARTHENWARE IN KILNS AND OVENS."
Sealed the 17th June 1859, and dated the 3rd January 1859.
PROVISIONAL SPECIFICATION left by the said Jacob Furnival, Thomas
Furnival, John Derbyshire, and Francis Joseph Emery at the Office of
the Commissioners of Patents, with their Petition, on the 3rd January
1859.
We, JACOB FURNIVAL, of Leamington, in the County of Warwick, THOMAS
FURNIVAL, of Coleridge, JOHN DERBYSHIRE, of Longton, and FRANCIS JOSEPH
EMERY, of Burslem, all in the County of Stafford, do hereby declare the
nature of the Invention for "IMPROVEMENTS IN APPARATUS FOR SUPPORTING
ARTICLES OF CHINA AND EARTHENWARE IN KILNS AND OVENS," to be as follows:-.
This Invention has for its object improvements in apparatus for supporting:
articles of china and earthenware in kilns and ovens. For these purposes;
bars or rods of clay or earthenware are formed or moulded with spurs or steps.
thereon at intervals apart, the spurs or steps forming part of and solid with
the bars or rods. In making up a frame for receiving a number of plates or

page_text: other like articles, three or more such bars or rod sare combined together by an
upper and a lower disc of clay; the lower ends of the three stepped or spurred
rods or bars are fixed in the lower plate. Slots are made in the upper disc,
and the upper ends of the stepped or spurred rods or bars are made so as to
pass through such slots and to be readily fixed therein, by which or other like
arrangement of frame the articles may be piled therein on the projecting spurs
or steps, and then be placed wholly into the saggar, in lieu of piling separately
in the sagger as heretofore.
In some cases ring frames of a circular or other shape are used formed in a
suitable manner to be placed one above the other, and so as to be kept apart a
suitable distance by moveable or fixed projections. Each frame is provided with
fixed or moveable spurs or steps projecting inwards, on to which the article to be
fired is placed, and is by them supported. The upper surface of each ring or
frame is in some cases made with a groove to receive the under projections of
the ring or frame above; or such under projections enter recesses formed in
the upper surfaces of the rings or frames to receive those projections.
Another method of supporting the article to be fired consists in providing
cranks with notches placed on the under side and corresponding recesses on
the upper side, each notching and fitting in the other. These cranks may be
either of the shape commonly in use, or of other convenient form.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jacob Furnival, Thomas Furnival, John Derbyshire, and
Francis Joseph Emery in the Great Seal Patent Office on the 2nd July
1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we JACOB
FURNIVAL, of Leamington, in the County of Warwick, THOMAS FURNIVAL,
of Coleridge, JOHN DERBYSHIRE, of Longton, and FRANCIS JOSEPH EMERY, of
Burslem, all in the County of Stafford, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of January, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said. Jacob Furnival, Thomas Furnival, John Derbyshire, and Francis
Joseph Emery, Her special license that we, the said Jacob Furnival, Thomas
Furnival, John Derbyshire, and Francis Joseph Emery, our executors, admi-
nistrators, and assigns, or such others as we, the said Jacob Furnival, Thomas

page_text: Furnival, John Derbyshire, and Francis Joseph Emery, our executors, admi-
nistrators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed;
should and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVEMENTS IN APPARATUS FOR SUPPORTING ARTICLES OF
CHINA AND EARTHENWARE IN KILNS AND OVENS," upon the condition (amongst
others) that we, the said Jacob Furnival, Thomas Furnival, John Derbyshire;
and Francis Joseph Emery, our executors or administrators, by an instru-
ment in writing, under our, or their hands and seals, or under the hand
and seal of one of us or them, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Derbyshire, on behalf of myself.
and the said Jacob Furnival, Thomas Furnival, and Francis Joseph Emery,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:-
This Invention has for its object improvements in apparatus for supporting
articles of china and earthenware in kilns and ovens. For these purposes
bars or rods of clay or earthenware are formed or moulded with spurs or steps
thereon at intervals apart, see Figure 1, the spurs or steps a, a, a, forming
part of and solid with the bars or rods. In making up a frame for receiving
a number of plates or other like articles, three or more such bars or rods are
combined together by an upper and a lower disc of clay; the lower ends of
the three stepped or spurred rods or bars are fixed in the lower plate b; slots
are made in the upper disc, and the upper ends of the stepped or spurred rods
or bars are made so as to pass into or through such slots, and to be readily
fixed therein, by which or other like arrangement of frame the articles may be
piled therein on the projecting spurs or steps, and then be placed wholly into
the saggar, in lieu of piling separately in the saggar as heretofore. Figure 2.
shows several plates piled on three such bars or rods; and Figure 3 is a plan
thereof.
In some cases ring frames c, c, of a circular or other shape, see Figures 4
and 5 are used, formed in a suitable manner to be placed one above the other
and so as to be kept apart a suitable distance by moveable or fixed projections
d, d; each frame is provided with fixed or moveable spurs or steps a, a, a,

page_text: projecting inwards, on to which the article to be fired is placed, and is by
them supported. The upper surface of each ring or frame c is in some cases
made with a groove to receive the under projections of the ring or frame
above, or such under projections enter recesses formed in the upper surfaces
of the rings or frames to receive those projections. Figure 6 shows another
form of support d.
Having thus described the nature of our Invention, we would have it under-
stood that what we claim are the combinations herein described.
In witness whereof, I, the said John Derbyshire, have hereunto set my
hand and seal, this Second day of July, in the year of our Lord
One thousand eight hundred and fifty-nine.
JOHN DERBYSHIRE. (L.S.)
