for the Invention of "IMPROVEMENTS IN MACHINES FOR PRINTING FROM
COPPER, STEEL, AND OTHER METAL PLATES, APPLICABLE ALSO FOR PRINTING
FROM LITHOGRAPHIC STONES."
Sealed the 24th April 1868, and dated the 28th October 1867.
PROVISIONAL SPECIFICATION left by the said Alfred James Waterlow,
Walter Blandford Waterlow, and Sydney Hedley Waterlow at the
Office of the Commissioners of Patents, with their Petition, on the
28th October 1867.
We, ALFRED JAMES WATERLOW, WALTER BLANDFORD WATERLOW, and
SYDNEY HEDLEY WATERLOW, all of Carpenters' Hall, London Wall, in the
City of London, Manufacturing Stationers, Lithographers, and Printers, do
hereby declare the nature of our said Invention for "IMPROVEMENTS IN MACHINES
FOR PRINTING FROM COPPER, STEEL, AND OTHER METAL PLATES, APPLICABLE ALSO FOR
PRINTING FROM LITHOGRAPHIC STONES," to be as follows:-
Our Invention has for its object the facilitating of the rapid printing of
impressions from steel, copper, or other metal plates, or from lithographic
[Price 8d.]

page_text: stones, so that by the use of our improved machine a greater number of
impressions may be obtained in a given time than is possible by the employ-
ment of any press or machine for the purpose hitherto constructed.
Our Invention consists in so constructing such machines that the engraved
plate is in them mounted on one side or end of a box or frame, which box or
frame is revolved or rotated by a horizontal shaft on which it is secured. On
that side or end of the box opposite to that on which the plate is carried are
two or more curved pieces or inclines, the object of which will be herein-after
explained. On the same shaft as the box or frame is keyed a large tooth
wheel, into which gears a pinion for driving inking roller; this it does by
means of another small tooth wheel on the spindle of inking roller. The large
tooth wheel carries also near to its periphery and at its inner side, that side
nearest to the revolving box or frame, a stud on which is mounted a small
roller; the purpose which this roller serves is to press forward two levers,
which being connected. with the scraper for removing the superfluous colour or
ink bring the scraper into contact with the plate during its passage over the
surface of the plate. The bed plate of the machine is provided with rollers
the same in number as there are curved pieces or inclines (as herein-before
mentioned) on one side or end of the revolving box or frame. Upon a
revolving motion being imparted to the box or frame these curved pieces or
inclines will press upon the rollers and thereby raise the box or frame so as to
will pre
keep the plate uniformly in contact with and maintain its contact with the
printing cylinder during
ring the tim
time that the paper or other material is receiving
the impression. To allow of this alternate gradual up-and-down motion of the
revolving frame or box, the said frame or box, although secured upon the
shaft so that it must revolve. therewith, is provided with slots or guides to
admit of this motion, which can only take place when that end or side of
frame or box carrying the plate is uppermost, stops being provided for the
slots or guides to prevent any vertical motion when the end of the frame with
the curved pieces or inclines is uppermost. The whole of the arrangement,
herein-above described is supported in suitable framing on a bed plate, and can
be arranged so as to be driven by either hand, steam, or other motive power.
This Invention, although described as for use in steel, copper, or other plate
printing, can be applied also for lithographic stone printing.

Patent, bearing date the Twenty-eighth day of October, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Alfred James Waterlow, Walter Blandford Waterlow, and Sydney
Hedley Waterlow, Her special licence that we, the said Alfred James
Waterlow, Walter Blandford Waterlow, and Sydney Hedley Waterlow, our
executors, administrators, and assigns, or such others as we, the said Alfred
James Waterlow, Walter Blandford Waterlow, and Sydney Hedley Waterlow,
our 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 MACHINES FOR
PRINTING FROM COPPER, STEEL, AND OTHER METAL PLATES, APPLICABLE ALSO FOR
PRINTING FROM LITHOGRAPHIC STONES," upon the condition (amongst others)
that we, the said Alfred James Waterlow, Walter Blandford Waterlow, and
Sydney Hedley Waterlow, our executors or administrators, by an instrument
in writing under our, 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 we, the said Alfred James Waterlow, Walter
Blandford Waterlow, and Sydney Hedley Waterlow, do hereby declare the
nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
Our Invention has for its object the facilitating of the rapid printing of
impressions from steel, copper, or other metal plates.

page_text: Our Invention consists in so constructing such machines that the engraved
plate is in them mounted on one side. or end of a box or frame, which box or
frame is revolved or rotated by a horizontal shaft on which it is secured. On
that side or end of the box opposite to that on which the plate is carried are
two or more curved pieces, or inclines, the object of which will be herein-after
explained: On the same shaft as the box or frame is keyed a large tooth
wheel, into which gears a pinion for driving the inking roller; this it does, by
means of another small tooth wheel on the spindle of inking roller. The large
tooth wheel carries also near to its periphery and. at its inner side, that side
nearest to the revolving box or frame, a stud on which is mounted a small
roller. The purpose which' this roller serves is to press forward two. levers
which being connected with the scraper for removing the superfluous colour or
ink bring the scraper into contact with the plate during its passage over the
plate's surface. The bed plate of the machine is provided with rollers, the
same in number as there are curved pieces or inclines (as herein-before
mentioned) on one side or end of the revolving box or frame.
Upon a
revolving motion being imparted to the box or frame these curved pieces, or,
inclines will press upon the rollers, and thereby raise the box or frame so as
to keep the plate uniformly in contact with and maintain its, contact with the
printing cylinder during the time that the paper or other material is receiving
the impression. To allow of this alternate gradual up-and-down motion. of.
the revolving frame or box, the said frame or box, although, secured upon the
shaft so that is must revolve therewith, is provided with slots or guides to
adinit of this motion, which can only take place when that end or side of frame
or box carrying the plate is uppermost, stops being provided for the slots or
guides to prevent any vertical-motion when the end of the frame with the.
curved pieces or inclines is uppermost. The whole of the arrangement herein-
above described is supported in suitable framing on a bed plate, and can be
arranged so as to be driven by either hand, steam, or other motive power.
In order that the nature of our said Invention and the means by which the
same is effected may be particularly described and ascertained, we append to
this Specification two Sheets of Drawings marked I. and II, and having
figures and letters of reference marked thereupon, the like letter being used
to denote a similar or corresponding part in each Figure.
In these Drawings, Figure 1 (Sheet Number I.) is a side elevation of a
machine constructed according to our invention for steel plate printing;.
Figure 2 is an end view; Figure 3, view of opposite end of machine; and
Figure 4 is a plan: In Sheet Number II., Figures 5, 6, and 7 shew the
revolving box or frame, herein-before mentioned, to an enlarged scale, Figure 5

page_text: being an end view, Figure 6 a side view; and Figure 7'a' plan of same; Figurerg

A is the revolving box or frame carrying at top, side, or end (at p, p,
Figure 6) the engraved plate to be printed from; B is the shaft on which
the revolving box or frame A is carried. The curved pieces inclinės at
opposite side or end of A are denoted by C; these are shewn by 'dotted lines
in Figure 1, and will be seen more clearly in Figure 5. The large tooth
wheel on shaft B is shewn by dotted lines in Figure 4, and marked D. The
pinion E is driven by the tooth wheel D, and in its turn drives pinion F on
spindle of inking roller. G is the intermediate pinion for driving inking
roller (see Figure 3).. The stud with roller for pressing forward the two
levers connected with scraper K is marked H, the levers I and 12; L; L, are
rollers on bed plate of machine on which the inclines C, C, press when a
revolving motion is given to A. The slots, in A, which serve as guides in the
alternate up-and-down motion are marked M, and their stops to prevent the
vertical motion when the end of A with the inclines C, C, is uppermost are
denoted by N,,N; n, n, are balance weights for the purpose of operating the
stops N. That end of A carrying plate is provided with a rack, as shewn in
Figure 5, for the purpose of revolving the impression cylinder O.. P is a cam
for working the gripper Q for holding the sheet to receive the impression
(see Figure 8). R, .Eigure 1, is a lever for bringing inking roller into
contact with plate; S is a small roller carried on A, and operating R; T is a
rod with gab for throwing R into and out of gear; U is a plate for cleaning
the engraved plate after the impression has been taken from the same; this
plate is brought into position and retained by means of cam u (Figure 6)
and lever u; W, Figure 6, is a cam on shaft B, operating levers X, X', so
as to raise and lower feeding board Y.
The sheet of paper to be printed is placed upon feeding board Y, which
rising, the gripper Q operated by the cam P takes hold of it. The rack upon
A revolves the impression cylinder O, and during the up-and-down motion
of A the plate passes under the paper on cylinder O, and in its passage
imprints the same. A with the plate next comes into contact with plate U
by which it is cleaned. The plate is brought into contact with inking roller
by the lever R, and after receiving its supply of ink is brought into contact
with the scraper K by means of the stud and roller H and levers I, 12; by
means of this scraper the superfluous ink is removed, and the plate is again
ready for printing.
Having now particularly described and ascertained the nature of our said

page_text: Invention, and the manner in which the same is to be performed, we wish it
to be understood that what we claim is
legal a
Firstly. The construction and use of machines for steel, copper, and other
plate printing in which the printing surface is carried at one side or end of a
box or frame made to rotate or revolve along with a shaft, which shaft carries
also a large tooth wheel operating through other tooth wheels and levers. the
other component (moving) parts of the machine.
And, secondly. The peculiar conformation of. that side or end of the box or
frame which is opposite to the side or end carrying the plate or printing.
surface, by which in conjunction with rollers on bed plate a gradual alternate.
up-and-down motion is imparted to the box or frame, so that the plate or
printing surface is kept in uniform contact with and with equal pressure.
against the printing cylinder during the operation of printing.
Thirdly. The slots or guides in the box or frame admitting of this motion,
and the stops for preventing such motion taking place excepting at the proper
time, all as described in this. Specification, or illustrated in the appended
Drawings.
. In witness whereof, we, the said Alfred James Waterlow,. Walter
Blandford Waterlow, and Sydney Hedley Waterlow, have hereunto
set our hands and seals, this Twenty-fourth day of April, in the year
of our Lord One thousand eight hundred and sixty-eight."
