Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY KEMPTON, of South Street, Pentonville, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Royal Letters Patent under the Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Twenty-third
day of March One thousand eight hundred and forty-seven, in the tenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Henry Kempton, my exors, admors, and assigns, Her
especial licence, full power, sole privilege and authority, that I, the said
William Henry Kempton, my exors, adñiors, and assigns, or such others as
I, the said William Henry Kempton, 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 COPYING PRESSES;"
in which said Letters Patent is contained a proviso, that I, the said
William Henry Kempton, shall cause a particular description of the nature of
my said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, to be inrolled in Her said
Majesty's High Court of Chancery, within six calendar months next and.

page_text: 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Henry Kempton, do hereby declare that the nature of my said 5
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 Drawings hereunto annexed, and to the figures and letters
marked thereon, that is to say:-
My Invention consists of a copying press so arranged that the act of 1
shutting a lid or cover acting on a bed or surface is by the resistance of a
spring or springs caused to produce the requisite pressure for copying letters
or other documents.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a plan of the copying press open, and Figure 2 a section
thereof, the lid or cover being closed. a is a rectangular frame; b, a bed or
surface constantly pushed upwards by a spring c, or more than one spring may
be used or other arrangements for giving the requisite elasticity between the
bed or surface b, and the lid or cover e may be resorted to; f, f, are stops to
prevent the bed or surface b rising too high. The letter or other document
with damped paper and other materials, as in other flat copying presses, are to
be placed on the surface of the bed b, and then the simple act of closing the
lid or cover e will cause the bed 6 to be pressed downwards, resisted by the
spring, and the lid is to be retained shut by a bolt g, or other means for a
short time, when the desired copyright will be obtained.
I would remark that I do not confine myself to the details shewn and
described, so long as the peculiar character of my Invention be retained; but
what I claim is, the mode of combining the parts, so that by the act of
shutting the lid or cover on to the bed, together with suitable elastic means
between them, there shall be suitable pressure obtained to form a copying
press.
In witness whereof, I, the said William Henry Kempton, have hereunto
set my hand and seal, this Thirtieth day of August, in the year of
W. H. (L.S.) KEMPTON.
