Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
HOLMES, of Derby, in the County of Derby, Cutler, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fifteenth day of May, in the seventh year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Henry
Holmes, Her especial licence, full power, sole privilege and authority, that
I, the said Henry Holmes, my exors, admors, and assigns, or such others as
I, the said Henry Holmes, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN THE MANUFACTURE OF BRICKS, TILES, AND
OTHER PLASTIC SUBSTANCES;" in which said Letters Patent is contained a proviso,
that I, the said Henry Holmes, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
to be inrolled in Her said Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Holmes, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):―
DESCRIPTION OF THE DRAWING.
Figure 1 is a plan of the machine; Figure 2 is an elevation; Figure 3 i3
a longitudinal section; Figure 4 is an end elevation. The letters of reference
correspond in each Figure.
A, A, A, A, Figure 1, is the table, which is supported and turns round upon
the pillar E, E, shewn in Figures 2 and 3; B, B, B, B, are angle pieces, cast
or screwed to A, A, A, A, and have their faces lined with brass; C, C, is a
plattin or piston, shewn at Figures 2, 3, and 9, the size of the brick on the
face, and has projecting pieces which work or slide in grooves in the pillars, as
shewn in Figure 9; N, a spindle, shewn in Figure 3, which slides through
the cross bar F, F, as shewn in Figure 3; this is drawn up by a barrel spring
acting upon the cross bar F, F, and under the collar upon the spindle.
D, D, D, is the frame supporting the table, and is shewn in Figures 2, 3,
and 4; G, G, in Figures 2, 3, and 4, is a cover to hide the barrel spring.
H, H, H, H, Figure 1, is a block fitted upon the pillar E above the table
A, A, A, A, and is intended to hold the moulds a, a, a, in Figures 1, 2, 3 and 4,
from sliding closer to the centre of the table.
I, Figure 1, is a latch to hold
the mould from sliding from the centre, and is capable of being turned up to
allow the mould to be taken out, as is shewn at Figures 1, 3, and 4. At
Figures 6 and 7 are shown the mould detached and in work at Figures 1, 2, 3,
and 4. Figure 1 represents one of the recesses in the table without the
mould, with the latch turned up ready to receive it. J, J, Figures 1, 2, 3,
and 4, is a pair of screw boxes, the lower of which is fixed to the rod N, the
upper one turns freely on that rod, the work of which is to depress or force
down the plattin C, C, when required to press or make the brick, tile, or other
plastic substance. The mode of working the machine is as follows:-The
mould, as shewn at Figures 6 and 7, being placed in the place appointed, as
shewn at Figure 1, and the latch being turned down to hold it in its place,
the clot of clay is put in the mould, and when this is done, and the superfluous
clay struck off, the table is turned round till under the plattin or piston C, C,
and is kept there by a notch cut in the under side of the table, into which notch
a catch O, shewn in Figure 8, and in work at Figures 2 and 4. This catch

page_text: is held up by a weight M, shewn at Figures 8, 1, 2, 3, 4, which is at the oppo-
site end of the lever to the catch. This being in the notch, the lever J is
pulled, which depresses the plattin C, C, and presses the brick, or tile, or other
plastic substance. This being returned to its original position, allows the
spring to raise the plattin, and while this is being done the mould placed at
right angles with the same will be ready to come under the same operation,
and the table being turned for the same will throw the pressed brick at a right
angle with the plattin, and will allow of the latch being turned up and the
mould being taken away.
In making tiles and other articles formed of plastic material, the moulds
and the plattin will have to be varied according to the figure of the article to
be made.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I make no claim to any
of the parts separately, nor do I confine myself to the details shewn, provided
the general character of my Invention be retained; but what I claim is, the
mode of arranging the table A suitable for receiving several moulds, combined
with the use of a suitable plattin presser C, as herein described, and the mould
marked 6 and 7.
In witness whereof, I, the said Henry Holmes, have hereunto set my
hand and seal, this Eleventh day of November, in the year of our
Lord One thousand eight hundred and forty-four.
HENRY (L.S.) HOLMES.
