Year: 1852

page_text: LETTERS PATENT to Charles Griffin, of Leamington Spa, in the
County of Warwick, Gentleman, for the Invention of "Im.
PROVEMENTS IN APPARATUS FOR FIXING TYPE OR PRINTING SURFACES
IN A CHASE."
Scaled the 17th January 1853, and dated the 9th November 1852.
PROVISIONAL SPECIFICATION left by the said Charles Griffin at
the Office of the Commissioners of Patents, with his Petition,
on the 9th November 1852.
I, CHARLES GRIFFIN, of Leamington Spa, in the County of Warwick,
Gentleman, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR FIXING TYPE OR PRINTING SURFACES
IN A CHASE" to be as follows:
This Invention consists of apparatus having corresponding in-
clines, parts of such inclines being moveable by means of screws, so
that the space occupied by the apparatus will be wider or narrower

page_text: according as the screws are moved in one direction or the other, at
the same time causing type or printing surfaces in a chase to be
retained correct and secure, or to be released.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Charles Griffin in the Great Seal Patent
Office on the 9th May 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
CHARLES GRIFFIN, of Leamington Spa, in the County of Warwick,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of November, in the
year of our Lord One thousand eight hundred and fifty-two, in
the Sixteenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Charles Griffin, Her
special licence that I, the said Charles Griffin, my executors, adminis-
trators, and assigns, or such others as I, the said Charles Griffin,
my executors, administrators, 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 Inven-
tion for "IMPROVEMENTS IN APPARATUS FOR FIXING TYPE OR PRINTING
SURFACES IN A CHAсE," upon the condition (amongst others) that I,
the said Charles Griffin, by an instrument in writing under my hand
and scal, 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 Charles Griffin, do hereby declare
the nature of the said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by
the following statement thereof (that is to say):
This Invention consists of apparatus having corresponding inclines,
parts of such inclines being moveable by means of screws, so that
the space occupied by the apparatus will be wider or narrower ac-
cording as the screws are moved in one direction or the other, at
the same time causing type or printing surfaces in a chace to be re-
tained correct and secure, or to be released. And in order that my
Invention may be more fully understood, I will proceed to describe
cording as the screws are moved in one direction or the other, at
the same time causing type or printing surfaces in a chace to be re-
tained correct and secure, or to be released. And in order that my
Invention may be more fully understood, I will proceed to describe
the means pursued by
G
DESCRIPTION OF THE DRAWING.
Figure 1, shows a plan of an apparatus constructed according to
my Invention partly in section. Figure 2, is one of the moveable
inclines shown separately; a, a, 'is a double incline; and b, b, are two
inclines which are capable, if moved towards each other or away
from each other as desired, by means of screws c, c, which screw
into the two moveable inclines b, b, such screws being moved by
a spanner on c. The moveable inclines b, b, are made with slots,
and they are connected to the inclines a, by means of screws d, d;
hence, although the parts b, b, are capable of movement along the
inclines a, a, they are retained from separating one from the other.
The parts a, and b, are shown in their contracted or narrowest con-
dition, and the width occupied by the parts a, and b, will be greater
and greater, according as the inclines b, b, are moved towards each
other by the screws c, c, and they would, by being so expanded,
cause type in a chace to be compactly held. I would remark that,
although I believe the arrangement shown to be the most convenient
and best for carrying out my Invention, I do not confine myself
thereto, as variations may be made therein so long as inclines are
arranged in combination with screws, and capable of being moved
thereby, in place of being set up by driving as heretofore.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that

page_text: what I claim is, the combining inclines with screws for fixing type
or printing surfaces in a chace.
In witness whereof, I, the said Charles Griffin, have hereunto
set my hand and seal, this Fourth day of May, in the year of
our Lord One thousand eight hundred and fifty-three.
Witness,
CHARLES EDWARD CLARKE,
30, Upper Parade,
Leamington Spa.
