Year: 1868

page_text: LETTERS PATENT to Charles Henry Gardner, of West Harding Street,
Fetter Lanc, in the City of London, Printing Machine Manufac-
turer, for the Invention of "IMPROVEMENTS IN LITHOGRAPHIC AND
ZINCOGRAPHIC CYLINDER PRINTING MACHINES."
Sealed the 23rd February 1869, and dated the 28th August 1868.
PROVISIONAL SPECIFICATION left by the said Charles Henry Gardner
at the Office of the Commissioners of Patents, with his Petition,
on the 28th August 1868.
I, CHARLES HENRY GARDNER, of West Harding Street, Fetter Lane,
in the City of London, Printing Machine Manufacturer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LITHO-
GRAPHIC AND ZINCOGRAPHIC CYLINDER PRINTING MACHINES," to be as follows:-
The object of this Invention is to ensure accuracy of lay and register
in printing by means of cylinder machines. For this purpose an
appliance is used supported on the feed table near to the gripper;
this appliance consists of a bar or rod carrying arms or plates made
adjustable at required distances apart on the bar or rod by screws or

page_text: otherwise. Two or more of these arms are provided at the ends with
adjustable bits, plates, or pieces; these are adjusted on the arms (pre-
ferably by screws and slots) to regulate and register the margin of the
sheet while being printed; they or the arms may be graduated. The
bar or rod and the arms thereon have a rocking or rising and falling
motion. This is best effected by mounting levers or arms on the bar or
rod, one carrying a friction roller working against the cylinder, and the
other being actuated or controlled by a cord. The ends of the adjustable
arms rise to allow the sheet to be taken from them by the gripper.
I sometimes use a gripper consisting of a bar or rod carrying a number
of arms, teeth, or tiues, formed with holes through which the bar or rod
is passed, and the arms, or teeth, or tines are adjusted and tightened in
place by screws, the teeth, arms, or tines being decreased in thickness
towards the working end.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Henry Gardner in the Great Seal Patent
Office on the 27th February 1869.
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 Twenty-eighth day of August, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Charles Henry Gardner, Her
special licence that I, the said Charles Henry Gardner, my executors,
administrators, and assigns, or such others as I, the said Charles Henry
Gardiner, 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 "IM-
PROVEMENTS IN LITHOGRAPHIC AND ZINCOGRAPHIC CYLINDER PRINTING MACHINES,"
upon the condition (amongst others) that I, the said Charles Henry
Gardner, my executors or administrators, by an instrument in writing

page_text: under my, or their, or one of their hands and seals, should particularly
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 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, that is to say :-
The object of this Invention is to ensure accuracy of lay and register
when printing by means of cylinder machines. For this purpose an
appliance is used supported on the feed table near to the gripper; this
appliance, which I call or entitle a "lay motion appliance," consists of a
bar or rod carrying arms or plates made adjustable at required distances
apart on the bar or rod by screws or otherwise. Two or more of these
arms are provided at the ends with adjustable bits, plates, or pieces;
these are set or adjusted on the arms, preferably by screws and slots, to
regulate and register the margin of the sheet while being printed; they
or the armis may be graduated. The bar or rod (with its arms, teeth, or
plates) has a rocking or rising and falling motion. This is best effected
by mounting levers or arms on the bar or rod, one carrying a friction
roller working against the cylinder, and the other being actuated and
controlled by a cord. The ends of the adjustable arms rise to allow the
sheet to be taken from them by the gripper.
I sometimes use an improved gripper which consists of a bar or rod
carrying a number of arms, teeth, or tines formed with holes, through
which the bar or rod is passed, and which arms, teeth, or tines are
adjusted and tightened in place by screws; the teeth, arms, or tines are
decreased in thickness towards the working end.
The accompanying Drawings represent an appliance or "lay motion
appliance" constructed according to my Invention and intended to
ensure accuracy of lay, margin, and register.
Figure 1 is a plan of this appliance. A is a bar or rod, on which are
mounted a number of arms or plates B', B2, B3, B', at any required
distances apart at which they are adjusted (and held) by screws b, b.
The arm B (shewn in edge view, Figure 2) has at one end an adjustable
bit C, the position of which on the arm is regulated by a screw d working

page_text: in a slot e. There is a similar bit C adjusted by screw d and slot e on
the arm B. The bits are adjusted to press upon the paper and determine
or regulate the required margin, being set more or less forward on the
arms according to the desired size or extent of margin. The arms B², B*,
or their bits C may be engraved or otherwise marked with a graduated
scale to secure precision.
Figure 3 is a perspective view of the bit C.
Figure 4 is an edge view of the bar B¹ or B. The free ends of these
bars rest
upon the paper.
A rocking or rising and falling motion is communicated to the
appliance by levers G, H, adjusted and held on the bar A by screws g, h.
Figure 5 is an edge view of lever G, and Figure 6 an edge view of
the lever H. i is a friction roller mounted in one end of the lever G,
and working against the cylinder of the printing machine. A cord or
string K is attached to one end of the lever H in order to work it and
regulate its action. The other end of this cord is attached to a
working part of the machine, so that the cord and lever work the
bar A so as to lift the ends of the arms B', B2, B3, B4, at the required
time to allow the sheet to be taken from them by the gripper.
J, J, Figures 7 and 7* are pedestals screwed on the feed table or lay
board, and acting as bearings to support the ends of the bar or rod A
which is held therein by set screws j, j.
Figure 8 is a plan of an improved gripper consisting of a bar or
rod M, shewn in transverse section Fig. 9, on which are a number of
arms or teeth N. Figure 10 is a side view of one of these teeth N.
Each tooth has a hole at one end, through which the bar or rod is passed.
I prefer to form the teeth N as shewn in Figure 10, that is to say, so that
the tooth decreases in thickness towards the working end. p, p, are
screws by which the arms or teeth N are adjusted and held in position
on the bar M. Hence instead of those teeth or arms being fixtures,
as is usual in ordinary grippers, they can be shifted and adjusted on the
bar M so as to accommodate them to and cause them to correspond
with the position of the arms or plates B1, B2, B3, B', of the lay motion
appliance, shewn in Figures 1 to 7 inclusively.
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim,-
First. The construction and employment of the appliance, or as I call

page_text: it lay motion appliance, hercin-before described, for securing accuracy of
lay, margin, and register, such appliance having its parts arranged and
combined substantially in the manner and for the purpose above set
forth.
Second. The construction and employment of a gripper having its
arms or teeth capable of being shifted and adjusted in place, substantially
in the manner and for the purpose described.
In witness whereof, I, the said Charles Henry Gardner, have here-
unto set my hand and seal, this Twenty-sixth day of February,
in the year of our Lord One thousand eight hundred and sixty-
nine.
Witness,
M. HENRY,
68, Fleet Street,
London.
