IMPROVEMENTS IN COPYING PRESSES
Year: 1874

page_text: LETTERS PATENT to Charles John Henry Kleinau, of King William
Strect, Strand, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN COPYING PRESSES."-A communication from abroad
by René Fouret, of the Firm of Hachette and Company, of Paris,
in the Republic of France.
PROVISIONAL SPECIFICATION left by the said Charles John Henry
Kleinau at the Office of the Commissioners of Patents, with his
Petition, on the 3rd March 1874.
I, CHARLES JOHN HENRY KLEINAU, of King William Street, Strand,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN COPYING PRESSES," to be as follows :—
The follower or moveable pressing plate of copying presses of the
ordinary construction is raised and lowered by means of a screw which
passes through a female screw tapped or formed in the central part of

page_text: the cross head, and is provided at its upper end with a lever or handle
for working the same, while its lower end is provided with a hub, flange,
or collar, which is held down or attached to the pressing plate by means
of a collar secured by screws.
In presses constructed in this manner the thread of the male screw
is exposed, and is therefore liable to get covered with dust. Morcover
as the lower end of the screw must necessarily turn loosely in its socket,
it follows that the pressing plate will not be held steadily but will be
liable to wobble about in its guides, and will not give a steady
pressure.
It is the object of the present Invention to obviate all these objections
and inconveniences, and this is effected by firmly securing on the top
of the follower or pressure plate a screw box, in which is formed or tapped
a female screw to receive the malo screw, whereby the follower or
pressing plate is raised or lowered. This male screw is provided at its
upper end with a hand wheel or lever, whereby it is actuated in either
direction, and it is also provided with a loose collar which is secured
to the top of the cross head of the press by screws or otherwise, and
forms one of the points of resistance to the thrust of the impelling
scrow. The screw box of the follower or pressing plate is turned
accurately externally, and extends up to and into and is made to fit the
socket formed in the cross head for the passage through it of the
impelling screw, so that the socket acts as a guide to the screw box.
The thread of the impelling screw is therefore completely covered in
and protected from damage by dirt or otherwise, and the screw box
being made to fit its socket, and being firmly socured to the follower or
pressing plate, this latter is found to rise and fall with a steady motion,
nd is effectually prevented from wobbling about.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Charlos
John Henry Kleinau in the Great Scal Patent Office on the 15th 30
September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
JOHN HENRY KLEINAU, of King William Street, Strand, in the County
of Middlesex, send greeting.

special licence that I, the said Charles John Henry Kleinau, my exe-
cutors, administrators, and assigns, or such others as I, the said Charles
John Henry Kleinau, my executors, administrators, and assigns, should

times thereafter during the term therein expressed, should and lawfully
might make, use, excrcise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN COPYING PRESSES," a communication to
him from abroad by René Fouret, of the Firm of Hachette and
Company, of Paris, in the Republic of France, upon the condition
(amongst others) that I, the said Charles John Henry Kleinau, my
executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, 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 on or before the Fifteenth day of September
One thousand eight hundred and seventy-four,
NOW KNOW YE, that I, the said Charles John Henry Kleinau, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing.
hereunto annexed and to the letters and figures marked thercon (that
is to say) :-
The follower or moveable presser plate of copying presses of the
ordinary construction is raised and lowered by means of a screw which
passes through a female screw tapped or formed in the central part of
the cross head, and is provided at its upper end with a lever or handle
for working the same, while its lower end is provided with a hub, flange,
or collar, which is held down or attached to the pressing plate by means
of a collar secured by screws.
In nossos constructed in this manner the thread of the mail screw is

page_text: exposed, and is therefore liable to get covered with dust. Moreover
as the lower end of the screw must necessarily turn loosely in its socket
it follows that the pressing plate will not be held steadily but will be
liable to wobble about in its guides, and will not give a steady
pressure.

page_text: being so arranged that the male screw is enclosed and protected from
dirt or dust obtaining access thereto as hercin set forth.
In witness whereof, I, the said Charles John Henry Kleinau, have
hereunto set my hand and seal, the Fourteenth day of September,
in the year of our Lord One thousand eight hundred and seventy-
four.
Signed, sealed, and delivered
by the above-named Charles
John Henry Kleinau, in the
