page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
CARTWRIGHT, of Brewer Street, Golden Square, in the Parish of Saint James,
Westminster, in the County of Middlesex, Engraver and Printer, send
greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of that part of the United Kingdom
of Great Britain and Ireland called England, bearing date at Westminster,
the Twenty-seventh day of July, in the fifth year of His reign, give and
grant unto me, the said Edward Cartwright, my exors, admors, and assigns,
His especial licence, full power, sole privilege and authority, that I, the said
Edward Cartwright, my exors, admors and assigns, during the term of years
therein mentioned, should and lawfully might make, use, exercise, and vend,
Invention
within England, Wales, and the Town of Berwick-upon-Tweed, my
of "IMPROVEMENTS ON OR ADDITIONS TO ROLLER PRINTING PRESSES;" in which
said Letters Patent there is contained a proviso that if I, the said Edward
Cartwright, shall not particularly describe and ascertain the nature of said
Invention, and in what manner the same is to be performed, by an instrument
in writing under my hand and seal, and cause the same to be inrolled in
His Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever thereby granted,
shall utterly cease, determine, and become void; as in and by the same,
relation being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Cartwright, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawing hereunto annexed, and the following
description thereof (that is to sny):-
My said Invention of Improvements on or Additions to the Cylindrical
Roller Printing Presses in common use, consists in certain methods of com-
municating an alternating or a backward and forward motion to them, and
also in a new construction of roller printing presses, all of them being
actuated by the powers of horses, steam engines, or other first movers of
machinery. In order, however, to explain more clearly the nature of these
improvements, I shall proceed to describe the Figures contained in the
Drawing, which, as aforesaid, is annexed to this Specification, and in which
said Drawing the same letters of reference indicate the similar parts in all
the Figures.
Fig. 1 is a front and Fig. 2 a side view of a cylindrical roller printing press.
A, A, &c., the press frame; B, B, &c., the rollers; C, the plank; D, is a
horizontal bevel wheel, affixed upon an upright shaft, which is to be turned
by any first moving power. This wheel has teeth only partly around it, as
shewn in Figs. 1, 2, and 3. It works into the two other bevel toothed wheels
E and F, which are affixed either on the top roller of the press, as shewn,
or they may be affixed upon the bottom rollers, and the horizontal wheel be
placed underneath them if more convenient. The wheel D communicates an
alternating or a backward and forward motion to them by the toothed part of
it taking into the one or the other of the toothed wheels E and F in suc-
cession, and thus also communicates a backward and forward motion to the
rollers and plank of the press.
Fig. 3 represents another method of communicating an alternating motion
to one or more cylindrical roller printing presses. Here the partially toothed
bevel wheel D is made to act alternately upon two bevel toothed wheels E
and F, mounted upon a horizontal shaft G, which may have upon it one or
more toothed spur wheels H, working into one or more other toothed spur
wheels I, aflixed either upon the axis of the top or the bottom rollers of the
printing presses, as may be most convenient. It is here shewn as being fixed
upon the axis of a top roller.
Fig. 4 is another method of communicating an alternating or backward
and forward motion to a cylindrical roller printing press. J is a shaft or axis
to which a rotatory movement is to be given by any first mover of machinery.
K is either a crank upon the shaft, or a stud affixed upon the side of a wheel;

page_text: upon the neck of the crank a coupling or half hole, or upon the stud a hole
L., at one end of the connecting rod M, acts, whilst another hole, coupling, or
half hole N, at the opposite end of the connecting rod M, acts upon another
stud affixed in the toothed segment O, which moves either upon an axis working
in centres in the two cheeks A, A, of the press, or upon a fixed axis. This
teethed segment O works into and turns backwards and forwards alternately a
toothed spur wheel P, affixed as here shewn upon the axis of the top roller B,
but the positions of the different parts may be changed if thought necessary,
and the motions be communicated from below, in which case the toothed spur
wheel P may be affixed upon the axis of the bottom roller. Two or more
cranks may also be placed along the shaft or axis J, at different angles, so as
to equalize the movement of the machinery, and each crank may be made to
actuate a separate press.
Fig. 5 is a section, and Fig. 6 a plan, of several roller printing presses
arranged in a circular manner, and of a revolving circular table, made of cast
iron or other proper material, and answering the purpose of the planks in the
usual printing presses. Here it becomes necessary that the rollers, instead of
being cylindrical as usual, should be conical, and also that the toothed wheels
which actuate them should be bevelled accordingly. The axes of the rollers
also must be inclined instead of being parallel to each other. The upper face
of the revolving table must also be flat or plane, but the lower face may be
made conical if preferred. Q. Q, &c., is the frame; R, R., &c., the rollers;
S, S, &c., the inclined axes of the rollers; T, the circular table; U, the hori-
zontal bevel toothed wheel which actuates the toothed bevel wheels V, V, &c.
upon the axis of the rollers; W, W, &c., other toothed bevel wheels, to
communicate similar and uniform movements to the rollers of each press;
✗, ✗, &c., friction rollers serving to guide the circular table in its course.
Y, the axis of the wheel U; Z, the step of it (shewn by dotted lines).
I do not mean or intend hereby to claim as my Inventions any of the parts
of these machines which are already known or in use, but I do hereby claim
the methods described of communicating an alternating or backward and
forward movement to the common cylindrical roller printing presses by means
of horses, steam engines, or other first moving powers, and also the con-
struction, arrangement, and method of working the printing presses with
conical rollers and revolving circular table, as above described.
In witness whereof, I, the said Edward Cartwright, have hereunto set
hand and seal, this Twenty-seventh day of September, in the
of our Lord One thousand eight hundred and twenty-four.
