IMPROVEMENTS IN LITHOGRAPHIC PRESSES
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of the Patent Office, London, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirteenth day of March, in the eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Moses Poole, my exors, adññors, and assigns, Her especial licence, full power,
sole privilege and authority, that I, the said Moses Poole, my exors, admors,
and assigns, or such others as I, the said Moses Poole, 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, the Invention of "IMPROVEMENTS IN LITHOGRAPHIC
PRESSES," communicated to me by a certain Foreigner residing abroad; in
which said Letters Patent is contained a proviso that I, the said Moses Poole,
shall cause a particular description of the nature of the said Invention, and in
what manner the same is to be performed, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and 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.
1. NOW KNOW YE, that in compliance with the said proviso, I, the said
Moses Poole, do hereby declare that the nature of the said Invention, and the

page_text: manner in which the same is to be performed, are fully described and ascer
tained 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:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side view of a lithographic press constructed according to
the Invention. Figure 2 is a longitudinal section, Figure 3 is a plan, and
Fig. 4 is an end view of the press. The other Figures shew detail views of
some of the parts, and in each of the Figures the same letters indicate the
same parts. a, a, is the framing of the press, the nature of which is clearly
shewn by the Drawings. 6 is the main or driving shaft which receives rotatory
motion by the crank handle c by manual labor, or the shaft may receive
motion from a steam engine or other power. d is a pinion fixed on the main
shaft which takes into and drives the cog wheel e on the axis or shaft f, and
on the axis or shaft f is.affixed the pinion g, which takes into and drives the
cog wheel h, which is fixed on the axis or shaft i, and the surface of the wheel
his broader at the part j, as is clearly shewn in Figure 5 of the Drawing, and
this part takes into and alternately drives the cog wheels and m, the cog
wheels l, m, being respectively fixed on the shafts or axes l, m, on which
are also affixed the chain wheels 12, m³, which give motion to the chains n
and o.
The chain.n gives motion to the chain wheel fixed on the cranks,
axis, or shaft p. The cranked axis or shaft p, by means of the connecting
róds q, q, gives motion to the carriage of the scraper or presser r, for in
this arrangement of press the scraper or presser r is moved to and fro over
the lithographic stone, which remains fixed and stationary. The scraper or
presser is of the ordinary construction, but is carried by two end plates s, 8,
which are combined into a carriage which moves on four wheels s¹, s¹, which
move on two fixed rails, one on each side of the machine, and the wheels aro
kept down by two other rails, which are above the wheels, being guided in their
action by flanges, as shewn. The lithographic stone t is fixed on a fixed table
or platform u, which is capable of being adjusted in its position by means of
screws u¹, u, and to one side of the carriage of the scraper or presser r is
affixed a rack s2, which, in its to and fro movements, gives motion to the
pinion on the axis of one of the two rollers w, w, on which is placed an
endless felt, and this endless surface receives ink from the roller x, and
transmits it to the inking roller y, the axes or necks at the ends of which are
carried by a carriage z, z, moving on four wheels z¹, on the same rails or

page_text: surfaces as the other wheels move, as before described, and to and fro motion
is communicated to the carriage of the inking roller, as herein-after explained.
The roller receives ink from the roller A, which revolves between two
straight edges B, forming a trough, into which and over the upper part of the
roller A a supply of lithographic ink is placed, and motion is communicated to
the roller by the pressure and movement of the endless surface on the rollers
w, and motion is communicated to the roller A by the surface pressure and
movement of the roller x. I would here remark, that the arrangement of
inking apparatus may be varied so long as it is suitable to transmit ink to an
inking roller or rollers suitably arranged for inking a lithographic stone,
whether the same be fixed as herein described or moveable. It should, how-
ever, be stated, that in case of the stone being made moveable and the scraper
fixed as to position in placing of moving to and fro over a stationary litho
graphic stone, then the inking roller will not require to be moved over the
stone, as the stone may have suitable motion, in addition to passing under the
scraper or presser, to pass under an inking roller supplied with ink, by the
working of the machinery. But it is preferred, in carrying out this part of
the Invention, that it should be used in conjunction with the other part of the
Invention before explained, which consists of giving motion to the presser or
scraper in place.cf giving motion to the stone. The carriage of the inking
roller receives motion in the following manner :-The chain o gives motion to
the chain wheel C fixed on the axis D, and on that axis is also affixed the
chain wheel E, which gives motion to the chain F, which takes into and gives
motion to the chain wheel G affixed on the cranked axis H, which, by means
of the connecting rods I, I, gives motion to the carriage of the inking roller.
The endless chains are kept distended by means of rollers J, J, J, as shewn.
I would remark, that other arrangements of mechanical parts may be
employed in place of those shown, for giving motion to the carriage of the
scraper or presser, and the details of such scraper and presser, and the
carriage thereof, may be varied, so long as the scraper or presser is suitably
arranged for being moved to and fro whilst the lithographic stone remains
stationary.
Having thus described the nature of the Invention, and the best means I
am acquainted with for performing the same, I would have it understood
that I do not claim any of the mechanical parts separately; but what I
claim is,
First, the so arranging a lithographic press as to cause the scraper or presser

page_text: And, secondly, I claim the so applying inking apparatus to a. lithographic
press that ink may be applied to an inking roller or rollers, and the surface of
the stone inked by the working of the press, as herein described.
In witness: whereof, I, the said Moses Poole, have hereunto set my hand
and seal, this "Eleventh day of September, in the year of our Lord
"AND BE IT REMEMBERED, that on the Eleventh day of September,
in the year of our Lord 1845, the aforesaid Moses Poole canie before our
said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, 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 purpose.
Enrolled, the Thirteenth day of September, in the year of our Lord
One thousand eight hundred and forty-five.
