IMPROVEMENTS IN PRESSES SPECIALLY ADAPTED TO THE COPYING OF LETTERS.
Year: 1860

page_text: LETTERS PATENT to Jean Joseph Baranowski, of Chalcot Terrace, in the
County of Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN
PRESSES SPECIALLY ADAPTED TO THE COPYING OF LETTERS.
Sealed the 21st August 1860, and dated the 24th February 1860.
PROVISIONAL SPECIFICATION left by the said Jean Joseph Baranowski
at the Office of the Commissioners of Patents, with his Petition, on
the 24th February 1860.
I, JEAN JOSEPH BARANOWSKI, of Chalcot Terrace, in the County of Mid-
dlesex, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PRESSES SPECIALLY ADAPTED TO THE COPYING OF LETTERS," to
be as follows:--
My Invention consists in constructing presses in the following manner :-
To the sides of a bed-plate I cast. or fix upright lugs, or form the lugs by
bending up a metal plate. In the lugs and near the ends are apertures for
the reception of the axes of two, excentric rollers. Each of these rollers has
cast on or formed in a piece with it a lever, and when the press is at rest, or
when pressure is not required to be exerted, the lever of one roller lies or
folds down upon the opposite roller. A top plate of metal or metal lined with
wood of corresponding size to the bed-plate is held up from the bed-plate, and
in contact with the excentric rollers by bands of elastic web or other suitable

page_text: material passed over both rollers, and connected to the upper surface of the
plate. The book containing the damped copying paper and the writing to be
copied, or the article to be pressed, is inserted between the plates; the levers
of the rollers are simultaneously raised one in each hand, and on being turned
down outwards the excentric rollers gradually increase in their power until the
maximum of their excentricity has been attained. After pressure has been
maintained a sufficient time the handles are returned to their original position,
when the book or other article may be removed from the press. The excentric
rollers being placed equidistant from the centre, and about midway from the
centre and the end of the press at each end, causes the pressure to be equally
distributed over the whole book or other article to be pressed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Joseph Baranowski in the Great Seal Patent Office
on the 24th August 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN JOSEPH
BARANOWSKI, of Chalcot Terrace, in the County of Middlesex, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of February, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto.
me, the said Jean Joseph Baranowski, Her special licence that 1, the said
Jean Joseph Baranowski, my executors, administrators, and assigns, or such
others as I, the said Jean Joseph Baranowski, 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVEMENTS IN PRESSES SPECIALLY ADAPTED TO THE COPYING
OF LETTERS," upon the condition (amongst others) that I, the said Jean
Joseph Baranowski, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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.

page_text: NOW KNOW YE, that 1, the said Jean Joseph Baranowski, 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 thereof, reference being had to the Drawings hereunto
annexed, that is to say :-
My Invention consists in constructing presses in the following manner :→
To the sides of a bed-plate I cast or fix upright lugs, or form the lugs by
bending up a metal plate. In the lugs and near the ends are apertures for
the reception of the axes of two eccentric rollers. Each of these rollers has
cast on or formed in a piece with it a lever, and when the press is at rest, or
when pressure is not required to be exerted, the lever of one roller lies
or falls down upon the opposite roller. A top plate of metal or metal lined
with wood, of corresponding size to the bed-plate, is held up from the bed-
plate and in contact with the eccentric rollers, by bands of elastic web or
other suitable material passed over both rollers, and connected to the upper
surface of the plate. The book containing the damped copying paper and.the
writing to be copied, or the article to be pressed, is inserted between the
plates; the levers of the rollers are simultaneously raised one in cach hand,
and on being turned down outwards the eccentric rollers gradually increase in
their power until the maximum of their eccentricity has been attained. After
pressure has been maintained a sufficient time the handles are returned to
their original position, when the book or other article may be removed from
the press. The eccentric rollers being placed equidistant from the centre, and
about midway from the centre and the end of the press at each end, causes
the pressure to be equally distributed over the whole book or other article to
be pressed.
In the accompanying Drawings, Figure 1 is a plan, and Figure 2 a side
view, of a press constructed according to my Invention, adapted to the copying
of writings of, say, octavo size. A is the bed-plate, the sides of which are
bent or turned up to form the lugs B, B, of which there are two on each side.
An aperture is formed in each lug for the reception of the axes a, a, of the
eccentric rollers C, C, shown in dotted lines at Figure 2. b, b, are lever
handles formed in a piece with or fixed to the rollers. In the Drawings the
parts are shown in the position in which no pressure is exerted, and with the
lever bandle of one roller folded down and resting upon the other roller.
D is a top plate of metal, with corrugations c, c, c. These corrugations are
not essential, but I prefer to use them as they strengthen a light plate, and
form so many separate surfaces for the rollers C, C, to act upon. d, d, are
metal loops passing over the rollers, and fixed to the top plate. The ends e, e,

page_text: of the bed-plate are bent round, as shown at, Figure 2, for the purpose of
strengthening it, and also for. holding a case containing damped blotting and
other paper. At Figure 2 a book for copying is shewn in its position in the
'press.
Figure 3 is a plan, and Figure 4 a side view, of a press constructed
according to my Invention, adapted to the copying of writings of, say, quarto
size. The arrangements of the levers are the same as those in the press last
described, but for the purpose of strength the bed-plate as well as the top
plate is corrugated. The bed-plate A is screwed or otherwise fixed on two
transverse ribbed plates E; E, the ends of which are turned up to form the
lugs B, B.
Although I prefer to form the top and bottom plates of metal, yet they may
be made entirely of wood, or of metal lined with wood, or vice versa, and
instead of bending up the metal: to form the lugs, the latter may be made in
separate pieces, and may be screwed or otherwise attached to the bed-plate.
And having now described the nature of my said: 'Invention, and, in what
manner the same is to be performed, I declare that I claim the construction
of presses in which pressure is exerted by means of two eccentric. rollers
'placed. and acting essentially in manner and for the purpose herein-before
described.

In witness whereof, I, the said Jean Joseph Baranowski, have here-
unto set my hand and seal, this Twenty-second day of August, One
thousand eight hundred and sixty.
