Year: 1867

page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the County
of Middlesex, Engineer and Patent Agent, for the Invention of "IM-
PROVEMENTS IN TYPOGRAPHIC PRINTING MACHINES."-A communication from
abroad by Auguste Hippolyte Marinoni, Builder, of 29, Boulevart St.
Martin, Paris.
Sealed the 11th October 1867, and dated the 18th April 1867.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the
13th April 1867.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN TYPOGRAPHIC PRINTING MACHINES," to be as follows:-
This Invention relates to improvements in machine typographic presses for
printing on both sides of a sheet by means of cylindrical stereotypes.. To
these machines I apply the running margin by the aid of an arrangement of
tapes indicated in the accompanying Drawing; in this manner I am enabled
to use as many feeding places as the speed of the machine requires.
In the machine represented in Sheet 1 of the Drawings I have shown four
cylinders D, D1, D2, D³ in red outline, as also the framing and gearing for
producing the necessary movements. In Sheet 2, I have shown the arrange-
ment of the additional feeding tapes in brown color, while the yellow lines
indicate other tapes arranged according to this Invention.

cylinders; B, B', printing cylinders; C, C¹, type cylinders; E, E¹, inking
rollers; F, F¹, distributing rollers; G, G¹, pressing rollers; H, H', drawing-

for conducting the sheets on to the receivers; K, eccentric shaft; L, feeding

machine I place the cylindrical stereotypes on the cylinders C, C, the sheets
to be printed being placed on the table L; their direction of motion is shown
by the arrows. The sheets are held by the rollers Q, and are carried along
by the tapes on cylinders D, D', D2, D³, thence pass to cylinder B, which by
its rotation prints the one side of the sheet by means of the stereotype carried
by cylinder C. The rotary motion continuing the sheet will be transferred
to cylinder B', which prints the reverse side of the sheet on cylinder C¹ in a
similar manner. The sheet printed on both sides is conducted to one or
other end of the machine, as shown at O, by means of the receiver, the
direction being determined by the guide I. Motion is imparted to the
receiver's inking rollers, distributing and drawing-off rollers, by the aid of
shaft K driven by bevil gear, on which shaft are also mounted the eccentrics
for producing the several movements. The inking in this improved printing
machine is effected in the same manner as in ordinary by means of rollers of
gelatine or other suitable material. The printing cylinders are covered with
india-rubber, cloth, or calico.. The stereotypes are produced by means of
the ordinary cylindrical moulds, and are secured to the cylinders by bolts and
sliding attachments in the usual manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the
11th October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of April, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Clark, Her special licence that I, the said William Clark, my executors,
administrators, and assigns, or such others as I, the said William Clark, my

page_text: 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 Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN TYPOGRAPHIC PRINTING MACHINES,"
a communication to me from abroad by Auguste Hippolyte Marinoni, Builder,
of 29, Boulevart St. Martin, Paris, upon the condition (amongst others) that
I, the said William Clark, 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.
NOW KNOW YE, that I, the said William Clark, do hereby declare the
nature of the 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 two Sheets of Drawings hereunto annexed, and to
the letters and figures marked thereon (that is to say):
:-
This Invention relates to improvements in machine typographic presses for
printing on both sides of a sheet by means of cylindrical stereotypes. To
these machines I apply the running margin by the aid of an arrangement of
tapes indicated in the accompanying Drawings; in this manner I am enabled
to use as many feeding places as the speed of the machine requires.
In the machine represented in Sheet 1 of the Drawings I have shown four
cylinders D, D1, D2, D3, as also the framing and gearing for producing the
necessary movements; in Sheet 2 I have shown the arrangement of the
additional feeding tapes in brown color, while the yellow lines indicate the
other tapes.
A, pulley and driving gear for communicating rotary motion to all the
cylinders; B, B', printing cylinders; C, C', cylinders carrying the type or
blocks; E, E', inking rollers; F, F, distributing rollers; G, G¹, inking
rollers; H, H', drawing-off rollers; I, guide for conducting the sheets in both
directions; J, J¹, tapes for conducting the sheets on to the receivers ;
K, eccentric shaft; L, feeding tables; M, M', receivers; 0, 0', receiving
tables;
Q, frictional margin rollers carried by bell-crank levers R, R, and
operated by cams P. In order to print in this machine I place the cylin-
drical stereotypes on the cylinders C, C', the sheets to be printed being placed
on the tables L; their direction of motion is shown by the arrows. The sheets
are held by the rollers Q, and are carried along by the tapes on cylinders

page_text: D, D1, D2, D3, thence passing to cylinder B, which by its rotation prints the
one side of the sheet by means of the stereotype carried by cylinder C.
The rotary motion continuing the sheet, will be transferred to cylinder B¹
which prints the reverse side of the sheet on cylinder C in a similar
manner. The sheet printed on both sides is conducted to one or other
end of the machine, as shown at 0, 0¹, by means of a receiver, the direction
being determined by the guide I. Motion is imparted to the receivers, inking
rollers, distributing and drawing-off rollers by the aid of shaft K driven by
bevil gear, on which shaft are also mounted the eccentrics for producing the
several movements.
The inking in this improved printing machine is effected in the same
manner as in ordinary by means of rollers of gelatine or other suitable
material. The printing cylinders are covered with india-rubber, cloth, or
calico. The stereotypes are produced by means of the ordinary cylindrical
moulds, and are secured to the cylinders by bolts and sliding attachments.
Having described the nature of this Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is, the improvements in machine
typographic presses herein described and represented in the Drawings, the
chief feature being the superposition of cylinders D, D¹, D3, D³, in the
manner described, in any suitable number according to the rate of supply
required of the machine.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Twenty-fifth day of September, in the year of our
Lord One thousand eight hundred and sixty-seven.
