page_text: TO ALL
WHOM HESE PRESENTS SHALL COME, I, THOMAS
GILBERT, late of Yarmouth, in the County of Norfolk, but at present residing
at Colchester, in the County of Essex, Gentleman, do send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent, bearing date at Westminster, the Seventh day of August, in
the fifty-first year of His reign, did give and grant unto me, the said Thomas
Gilbert, my executors, administrators, and assigns, His special licence, full
power, sole privilege and authority, that I, the said Thomas Gilbert, iny exe-
cutors, administrators, and assigns, during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within that part of
our United Kingdom of Great Britain and Ireland called England, Wales,
and Town of Berwick-upon-Tweed, my new Invention of "CERTAIN IMPROVE-
MENTS IN MACHINERY FOR DELIVERING OF BRICKS, TILES, ORNAMENTS, POTTERY
WARE, AND OTHER ARTICLES MADE IN MOULDS AFTER THE MOULDS ARE FILLED;" in
which Letters Patent there is contained a proviso obliging me, the said
Thomas Gilbert, under my hand and seal, to cause a particular description of
the nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled His Majesty's High Court of Chancery, within two
calendar months next and immediately after the date of the said recited
Letters Patent, as in and by the same, (relation being thereunto had,) may
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Gilbert, do hereby declare that my said Invention is described in
manner and form following; that is to say:-

page_text: Fig. 1 is a perspective view of the machine on a scale of one inch to a
foot for bricks, but the size of the different parts must vary according to the
purpose intended. A, A, the main axle or shaft, with two wheels, B and D,
firmly fixed on it, and worked by any power applicable to machinery. B, the
upper shaft wheel; C, the tempering wheel fixed to the axle for tempering
the composition in the tub; D the lower shaft wheel acting upon E, which
removes the full moulds from under the cylinder, and replaces them with
empty ones. E, E, E, the moulding table. a, b, c, spaces or apertures for
receiving the moulds for the bricks. When other articles are required, the
form of the apertures or the moulds may be varied. G, the cylinder or clay
tub to receive the composition. N. B.-There is nothing new in the con-
struction of this clay tub but its situation in this machine. H, the bench on
which the cylinder stands.
Fig. 2, part of a wheel which may be used instead of D, for light work.
Fig. 3, plan of the upper part of the moulding table. A, B, two spaces for
receiving the moulds. C, C, two brick frames or moulds occupying tho
third space.
Fig. 4, plan of the under part of the moulding table; this part must be
firmly fixed to Fig. 3, with screws, pins, or otherwise.
Fig. 5, a pivot that goes through Figs. 3 and 4, and works in a socket in
the centre of the stool, Fig. 6, which together with Figs. 3 and 4, form the
moulding table shown in Fig. 1.
Fig. 7, plan of the bench on which the cylinder rests.
Fig. 8, represents a brick mould frame open. a is a representation of a
brick moulded on a pallet board; b, a pallet board; c, the pallet board taken
off to shew the pins it rested upon at d, d. It is sufficiently high for a person
to put his hand under to take cut the bricks (or other moulded article);
there are orifices at the bottom of the mould frame to let out the water.
This mould is furnished with hinges or other means to open and shut, so that
by lifting up the top and pulling down the front, the bricks or other articles
are delivered on pallet boards.
Fig. 9 shews the bottom of the moulding frame.
Fig. 10, the end and a method of fastening it. The mould is not drawn
on a scale of an inch to a foot, as it would be too diminutive to explain the
principle. To work the machine,-the moulding table being furnished with
the necessary frames for the articles required to be made, and the cylinder G
with composition, the power is applied to the top of the shaft A, A, when
the upper wheel B turns the wheel C, which works the axle in the cylinder
G, and fills the moulds with the composition; the lower wheel D acting on E,

page_text: having just a sufficient number of cogs to turn the moulding table one third
round, removes the moulds that are filled from under the cylinder, and replaces
them with empty ones; the moulded articles being on pallet boards, are
carried away by hand as fast as the machine presents them, and other pallet
boards are put in the moulding frame during the operation; the wheel B
having a deficiency of the same number of cogs, causes the tempering wheel
C to be at rest while the moulds are changing, and prevents a pressure on
the moulding table; likewise, there being a deficiency of cogs on the wheel D,
causes the moulding table E to be at rest during the time the moulds are
filling, so that the horse, or whatever power is applied, does not stop in any
part of the operation; by placing two, three, or four moulding tables round
the main axle or shaft, the same motion will work them all. Bricks, tiles,
ornaments, pottery, and other articles are made by this machine, by changing
the form of the moulds and varying the moulding table.
In witness whereof, I, the said Thomas Gilbert, have hereunto set my
hand and seal, the Third day of October, in the fifty-first year of the
reign of our said Sovereign Lord George the Third, by the Grace of
God, of the United Kingdom of Great Britain and Ireland King,
Defender of the Faith, and in the year of our Lord One thousand eight
Inrolled the Fifth day of October, One thousand eight hundred and
eleven.
