page_text: LETTERS PATENT to Isaac Sharp, of Middlesborough, in the County of
York, Estate Agent, and William Bulmer, of the same Place, Brick
and Tile Maker, for the Invention of "IMPROVEMENTS IN APPARATUSES FOR
THE MANUFACTURE AND FOR THE DRYING OF BRICKS, TILES, AND OTHER LIKE
WARE."

Sealed the 22nd May 1861, and dated the 26th November 1860.
PROVISIONAL SPECIFICATION left by the said Isaac Sharp and William
Bulmer at the Office of the Commissioners of Patents, with their Petition,
on the 26th November 1860.
We, ISAAC SHARP, of Middlesborough, in the County of York, Estate
Agent, and WILLIAM. BULMER, of. the same Place, Brick and Tile, Maker, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUSES FOR THE MANUFACTURE AND FOR THE DRYING OF BRICKS, TILES, AND
OTHER LIKE WARE," to be as follows:-.
Our improvements in apparatuses for the manufacture of bricks, tiles,
pipes, and other like ware, consist in the. employment (in a trough or case in
or to which the moulds or dies are fitted, and into which clay from a pug.
mill or other source is placed or driven) of a shaft with two or more curved
arms or "wipers." in combination with a cranked lever free to play upon a fixed

page_text: point, on which it is centred or hung. The lever is so placed with regard to
the wipers on the shaft, that upon the revolution of the shaft one wiper comes
in contact with the short arm of the lever, causes it to move on its centre,
and consequently the long arm to be raised, whereby the clay is prevented
from being carried round by the next "wiper," and at the same time a species
of channel is formed in the direction of the moulds or moulding orifices in
the box or case. The following or next wiper in succession bears against the
raised long arm of the lever,. depresses it, and thereby forces the clay in front
of it through the moulds or moulding orifices, and so on.
Our improvements in apparatuses for drying bricks, tiles, and other like
ware, or pottery ware, consist in the construction of drying sheds, with grooves
or channels formed at or in the sides thereof for the reception of movable
shelves, upon which the articles to be dried are supported. Fire contact with
the ground is broken, and the products of combustion are made to pass through
the articles on their transit to the chimney.
SPECIFICATION in pursuance of the conditions of the Letters 'Patent, filed
by the said Isaac Sharp and William Bulmer in the Great Seal Patent
Office on the 25th May 1861.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ISAAC
SHARP, of Middlesborough, in the County of York, Estate Agent, and
WILLIAM BULMER, of the same Place, Brick and Tile Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of November, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her beirs and successors, give and grant unto us,
the said Isaac Sharp and William Bulmer, Her special licence, that we,
the said Isaac-Sharp and William Bulmer, our executors,, administrators, and
assigns, or such others as we, the said: Isaac Sharp and William Bulmer,
our éxecutors, administrators, and assigns, should at any time: agree with,
and no others, from time to time and at all times. thereafter during the
terin 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 APPARATUSES
FOR THE MANUFACTURE AND FOR THE DRYING OF BRICKS, TILES, AND OTHER LIKE
WARE," upon the condition. (amongst others) that we, the said Isaac Sharp

page_text: and William Bulmer, or one of us, our executors or administrators; by an
instrument in writing under our, or their, or one of our or their hands and seals,
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 we, the said Isaac Sharp and William Bulmer,
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 thereof, reference being had to the Drawings
hereunto annexed, that is to say:
Our improvements in apparatuses for the manufacture of bricks, tiles, pipes,
and other like ware, consist in the employment in a trough or case in or to
which the, moulds or dies are fitted, and into which clay from a. pug mill or
other source is placed, or driven, of a shaft with two or more curved arms or
wipers in combination with a cranked lever free to play upon a fixed point on
which it is centred or hung. The lever is so placed with regard to the wipers
on the shaft, that upon the revolution of the shaft, one wiper comes in contact
with the short arm of the lever, causes it to move on its centre, and conse-
quently the long arm to be raised, whereby the clay is prevented from being
carried round by the next "wiper," and at the same time a species of channel
is formed in the direction of the moulds or moulding orifices in the box or
The following or next wiper in succession bears against the raised long
arm of the lever, depresses it, and thereby forces the clay in front of it through
the moulds or moulding orifices, and so on.
case.
Figure 1 of the accompanying Drawings is a side elevation, and Figures 2
and 3 are sections of apparatuses for the manufacture of bricks, tiles, and
other ware constructed according to our Invention. A is the trough or case
supported upon rollers or wheels B, B, in which the wiper is free to revolve.
a is the shaft on which the wiper is mounted, supported in bearings in the
sides of the trough A, and carrying the curved arms or wiper blades b; b¹; c is
the shaft.carrying the cranked lever d; d. Motion is communicated to the
shafts a and c in the following manner:-The fly wheel e, to which motion is
communicated, is mounted on a shaft carrying a pinion f gearing into a
toothed wheel on.a. shaft also. carrying a pinion h in gear with another
toothed wheel i mounted on a shaft k, which also carries an eliptical rack
in gear with a similar rack m mounted on the wiper shaft a. Supposing the
wiper blades b; b, and the cranked lever d, d¹, to be in the position. shown by
the full lines in Figure.3, then on motion being communicated to the shaft a,

page_text: #
and clay being fed into the apparatus from a pug mill or other source, the
wiper blade will move to the position shown by the dotted lines in its course,
striking the arm .d', taking: it into the position shown by the dotted lines.
During the ascent of the. wiper blade b, the other blade 6 has descended into
the position shown by the dotted lines, and in its course has taken clay with
it, which it drives forward under the lever arm d; to the mould o; the lever
arm d prevents the clay being carried round with the wiper, and forms with
the bottoin: of the box a channel or passage to the mould, until the continued
advance of the wiper causes the lever arm' d to descend and assist in ejecting
the clay; the wiper continuing to revolve, comes in contact with the.arm.d¹;
and raises the arm d to the position shown by the dotted lines, and so on for
each revolution of each wiper blade. The moulded articles are led away over
rollers in the manner common to brick and tile making machines. The
mould shown at:o is used for the manufacture of perforated bricks, and that
shown at Figure 4 for the manufacture of solid bricks; any form of mould-
can, however, be used in the apparatus. Although we have shown the trough
mounted on wheels, it will be readily understood that they may be dispensed
with.
.. Our improvements in apparatuses for drying-bricks, tiles, and other like
ware, consist in the construction of drying sheds, with grooves or channels
formed at or in the sides thereof for the reception of movable shelves, upon
which the articles to be dried are supported. Fire contact with the ground is
broken, and the products of combustion are made to pass through the articles
on their transit to the chimney.
Figure 5 is an external elevation; and Figure 6, a horizontal section of a
shed or apparatus constructed in this manner; Figure 7 is a section through
the-line A, B, and Figure 8 a section-through the line E, F; of Figure 6.
at; a, a, a, are the sheds built with ledges b, b, on which the shelves c, c," ȧre
laid; one of the shelves is shown in plan and 'end view detached at Figure 9.
They are made of flat bars of iron d, d, and of angle iron c, c, as shown.
The shelves are laid on the ledges b; b, and the articles to be dried are laid on
them, as shown in Figure 6; by this means they are easily placed in position,
and with equal facility-taken down. e; e, are fire-places for heating the sheds,
and f,f, are flues leading therefromn to the chimneys' g, g.`
And having now described the nature of our said Invention, and in-what-
manner the same is to be performed, we declare that we claim,
First, constructing apparatuses for the manufacture of bricks, tiles; and other
like ware, with a shaft carrying two or more curved arms or wipers made to
work in a box or trough, in combination with a cranked lever, substantially

page_text: in manner herein-before described and illustrated at Figures 1, 2, and 3 of the
accompanying Drawings.
Second, the construction of sheds or apparatuses for drying bricks, tiles, and
other like ware with grooves or channels for the reception of movable shelves,
substantially in manner herein-before described with reference to Figures
5, 6, 7, 8, and 9 of the accompanying Drawings.
In witness whereof, I, the said Isaac Sharp, have hereunto set my hand
and seal, this Twenty-third day of May, One thousand eight hundred
and sixty-one.
ISAAC SHARP. (L.S.)
