IMPROVEMENTS IN PRESSES
Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, the
said HENRY CURZON, of the Borough of Kidderminster, in the County of of
Worcester, Machinist, send greeting.
WHEREAS. Her most Excellent Majesty Victoria, by Her Letters Patent
under the Great Seal of Great Britain, bearing date at Westminster,
the Sixteenth day of April, in the second year of Her reign, did, give
and grant unto me, the said Henry Curzon, my exors, adiñors, and assigns,
Her especial licence, full power, sole privilege and authority, that I,
the said Henry Curzon, my exors, admors, and assigns, and such others
as I, the said Henry Curzon, my exors, admors, and assigns, should at
any time agree with, and no others, from time to time and at all times
hereafter during the term of years therein mentioned, should and lawfully
might make, use, exercise, and vend, within England and Wales, and the
Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN PRESSES;"
in which said Letters Patent there is contained a proviso that I, the said
Henry Curzon, 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 imme-
diately after the date of the said in part recited Letters Patent, reference
being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Curzon, do hereby declare the nature of my Invention, and the

page_text: 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):-
My Invention relates to a certain mode of combining mechanical instru-
ments into a press, as hereafter described.
DESCRIPTION OF THE DRAWING.
The Drawing shows a perspective view of a press constructed according to
my Invention.
a is the bed of the press; and b, b, two uprights or side
framings of the press, which are strongly affixed to or form part with the bed
of the press; c, c, are two ties or braces which combine the two side framings
b, b, and keep the upper part of the frame stiff. Each of the side framings b
has two racks b¹ formed thereon, or securely affixed thereto, as is clearly
shown in the Drawing; dis the platten or moving surface of the press, having
bearings e, e, in which the two axes f, f, turn.. On each of the axes f, f, there
is a screw wheel g, which respectively take into and are driven by the screw h,
which turns in suitable bearings at one side of the framing, as will readily be
understood on examining the Drawing; and in addition to the screw wheels
g, g, the axes f, f, have each two toothed pinions i, i, affixed thereto, which
take into the racks b¹ on the uprights or side framing b, consequently when
the screw is turned the axes f, f, will be turned, and by means of their
pinions taking into the toothed racks the platten will be caused to raise or
fall according to the direction in which the screw h is turned, and motion is
communicated to the screw h by means of the axes J, which is turned by a
winch handle k, there being a bevelled toothed wheel affixed in the axes j,
such bevelled tooth wheel taking into and driving the wheel affixed to the
upper end of the screw h. By this combination or arrangement of parts a
very powerful yet simple construction of press is obtained, and I would remark
that the variations may be made in the driving means which I have described
to the press, and yet retain the peculiar combination of the racks b¹, the
axes f, f, and the pinions i, i, for it will be evident when greater power
is desired, that instead of the winch handle k a screw wheel may be affixed
on the axesj, and there may be an additional axes turned by a winch handle in
suitable bearings, with a screw on it taking into and driving the screw wheel
on the axes j, or that the screw h may be dispensed with, and in place of the
screw wheels g, g, to apply two cog wheels (gearing into each other) on the
shafts or axes f, f, and either applying a crank handle to one of the axes f, or
when greater power is desired to have bearings on the platten for a third axes;

page_text: on which axes is to be affixed a pinion to take into and drive one of the cog
wheels on the axes f, all which will readily be arranged by a mechanic capable
of making the other parts of the press.
Having thus described the nature of my Invention, I would remark that I
lay no claim to any of the parts separately, and it will be evident that in place
of having the racks 6¹ stationary, they may be affixed to the platten or
moveable part of the press, and in such case the axis of the pinion i would be
stationary as to their position; but what I claim is the mode of constructing
presses by combining the parts b¹, b¹, b¹, b¹, f, f, and i, i, i, i, as above
described.
In witness whereof, I, the said Henry Curzon, have hereunto set my
hand and seal this Eleventh day of Octcher in the wo
HENRY CURZON. (LS.)
AND BE IT REMEMBERED, that on the Twelfth day of October, in
the year of our Lord 1839, the aforesaid Henry Curzon came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that pourpose.
Inrolled the Sixteenth day of October, in the year of our Lord One
thousand eight hundred and thirty-nine.
