IMPROVEMENTS IN CYLINDER PRINTING PRESSES
Year: 1871

page_text: LETTERS PATENT to Charles Henry Gardner, of West Harding Street,
Fetter Lane, in the City of London, Printing Machine Manu-
facturer, for the Invention of "IMPROVEMENTS IN CYLINDER PRINTING
PRESSES." A Communication from abroad by Victor Eugene
Mauger, of Reade Street, New York, in the United States of
America.
Sealed the 5th March 1872, and dated the 6th September 1871.
PROVISIONAL SPECIFICATION left by the said Charles Henry
Gardner at the Office of the Commissioners of Patents, with his
Petition, on the 6th September 1871.
I, CHARLES HENRY GARDNER, of West Harding Street, Fetter Lane,
5 in the City of London, Printing Machine Manufacturer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN CYLINDER
PRINTING PRESSES," communicated to me from abroad by Victor Eugene

page_text: .
Mauger, of Reade Street, New York, in the United States of America,
to be as follows :—
* This Invention relates to the construction and arrangement of the
grippers or gripers of cylinder printing presses and to the means of
connecting the same with the apparatus, the object being to render the 5
said grippers or gripers adjustable in order that they may be regulated,
adapted, or accommodated for holding various sizes of sheets of paper or
like material to be acted on or printed by the press, (instead of only
holding sheets of one size as in ordinary arrangements.)
The grippers are secured to vibrating rods and they are controlled in 1
their motions by cams or other usual and suitable contrivances. Now,
ordinary grippers extend a certain fixed or determinate distance from
their carrying rods, whereas, according to this Invention, the improved
grippers fit through perforated sleeves, bushes, collars, or the like,
mounted upon the rods, or through apertures in the rods, and they can 1
be pushed, drawn, slidden, or adjusted therein to the required length, to
suit or accommodate themselves to various sizes of sheets to be held
between or by them; and when so adjusted or regulated they are
clamped or kept in proper position by set screws or other equivalent
adjustable fastening contrivances. Instead of rendering the grippers 2
thus adjustable on the rods, they may be made extensible by forming
them in two or more sections or telescopic portions, so that one or an
outer portion may slide or move over another or inner portion, or the
latter may slide or move under the former.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 21
filed by the said Charles Henry Gardner in the Great Seal Patent
Office on the 6th March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
HENRY GARDNER, of West Harding Street, Fetter Lane, in the City of
London, Printing Machine Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of September, in the
year of our Lord One thousand eight hundred and seventy-one, in the
30

page_text: thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Henry Gardner, Her special
licence that I, the said Charles Henry Gardner, my executors, dminis-
trators, and assigns, or such others as I, the said Charles Henry
Gardner, 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 Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN CYLINDER PRINTING PRESSES," Communicated to me
from abroad by Victor Eugene Mauger, of Reade Street, New York, in
the United States of America, upon the condition (amongst others)
that I, the said Charles Henry Gardner, my executors or adminis-.
trators, by an instrument in writing under my, or their, or one of their
5 hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, 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 Charles Henry Gardner, 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 thereof, reference being had to the
accompanying Drawings and to the letters and figures marked thereon,
5 that is to say :—
This Invention relates to the construction and arrangement of the
grippers or gripers of cylinder printing presses and to the means of
connecting the same with the apparatus, the object being to render the
said grippers or gripers adjustable in order that they may be regulated,
10 adapted, or accommodated for holding various sizes of sheets of paper or
like material, to be acted on or printed by the press, instead of only
holding sheets of one size as in ordinary arrangements.
The grippers are secured to vibrating rods and they are controlled in
their motions by cams or other usual and suitable contrivances. Now,
35 ordinary grippers extend a certain fixed or determinate distance from
their carrying rods, whereas, according to this Invention, the improved
grippers fit through perforated sleeves, bushes, collars, or the like,

page_text: mounted upon the rods or through apertures on the rods, and they can
be pushed, drawn, slidden, or adjusted therein to the required length to
suit or accommodate themselves to various sizes of sheets, to be held
between or by them, and when so adjusted or regulated they are clamped
or kept in proper position by set screws or other equivalent adjustable 5
fastening contrivances. Instead of rendering the grippers thus ad-
justable on the rods, they may be made extensible, (and thereby
adjustable,) by forming them in two or more sections or portions, so that
one or an outer portion may slide or move over another or inner portion,
or the latter may slide or move under the former.
The accompanying Drawings represent apparatus constructed accord-
ing to this Invention. Figure 1 is a vertical transverse section of a
printing cylinder provided with the improved gripper or griper
attachment; Figure 2 is a side view of the same; Figure 3 is a
detailed sectional side view of a modification of the same.

Ordinary presses now in use are provided with grippers of a certain
size and description, which will answer for all ordinary purposes, but
where one cylinder is used on a double feeder press, as, for example, the
oscillating cylinder on the well known "Wharfedale," and registers two
sets of grippers for holding the sheets alternately at opposite ends, such 2
grippers are only useful for certain defined sizes of sheets of paper
unless the grippers are made adjustable. To thus render them
adjustable is the object of this Invention.
A is a printing cylinder; it is provided with two sets of grippers
B, B', mounted according to this Invention. The grippers are secured 2
to vibrating rods a, a, and controlled in their motions by cams or other
equivalent mechanical means in any ordinary manner.
Ordinary grippers are made to extend a suitable distance from the
rods to hold sheets of corresponding size, whereas the improved grippers,
constructed and arranged according to this Invention, fit through g
perforated sleeves c, c, which are mounted upon the rods a, or they may
be mounted through apertures in the said rods. They are adjusted on or
in the rods to suit the several various sizes of sheets of paper to be held
between them and clamped in such position by set screws b, b,
or other similar means. The grippers, instead of being adjustable on 3
the rods may be made extensible (and thus adjustable) by forming

page_text: them in sections, as shown in Figure 3, so that the outer section may be
moved or slidden on the other or inner section.
Having now described the nature of the said Invention and in what
manner the same may be performed, I declare that I claim, the
adjustable grippers applied to the printing cylinders, substantially as
herein-before described.
In witness whereof, I, the said Charles Henry Gardner, have
hereunto set my hand and seal, this Fifth day of March, in the
year of our Lord One thousand eight hundred and seventy-
two.
Witness.
