page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "INDOWS DRINTING MACHINERY" A communication
Sealed the 21st August 1857, and dated the 10th June 1857.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
10th June 1857.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN PRINTING MACHINERY," to be as
follows:-
This Invention of improvements in printing machinery relates, in the first.
place, to a novel or improved arrangement or construction of parts, whereby
the sheets of paper to be printed on are fed into printing machines; and,
secondly, to improved means of delivering the printed sheet from the machine,
and depositing on a receiving board or table.
The first part of the Invention consists in arranging the drop roller, whereby
the sheet of blank paper is carried into the machine in such a manner that
this roller may have a regular motion imparted to it, dependent upon the
surface speed of the impression cylinders and type cylinders.
Heretofore the rotation of the drop roller was so far independent of these

page_text: parts, that an increase in the speed of impression, or type cylinders, or the
carrying tapes, did not necessarily involve an increase in the surface speed of
the drop roller, and the consequence was that it was very difficult, if not
entirely impossible, to obtain a perfect register; whereas by causing the drop
roller to derive its rotary motion by means of suitable gearing from the
impression rollers or travelling tapes, all the parts are made to travel at the
same relative speed, and the paper will be carried in with such regularity
that, when the parts are adjusted, a perfect register may be obtained.
The second part of the Invention relates to an improved mode of working
the fly frame, into which the printed sheets are delivered, and are deposited
upon the receiving table.
As now constructed the cam shaft carrying the fly cams is placed under the
centre of the press at the greatest possible distance from the fly frames, to which
it is intended to give motion by the intervention of geared levers, connecting
rods, intermediate levers, bell cranks, and other complicated contrivances.
This mode of transmitting the motion through so many parts is objectionable,
in consequence of the wear and tear of such parts causing play or looseness
in the parts severally, the whole effect of this looseness evincing itself in the
inaccurate operation of the fly frames. Moreover, these connecting rods, &c.
are of great inconvenience to the pressman, in getting in and out of the pit
underneath the press, to attend to the regulation of the fly cams, inking
apparatus, and other, working parts of the machine.
The improvement consists in placing a fly cam shaft at each end of the
press, and actuating such shafts by suitable toothed gearing mounted on side
shafts, geared to a central main shaft, causing the cams on the cam shaft to
act more directly on the fly frames than heretofore, and avoiding the incon-
veniences above mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office
on the 10th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME; I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of June, in the year of our Lord 3
One thousand eight hundred and fifty-seven, in the twentieth year of Her

page_text: reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Edward Newton, Her special license that I, the said William
Edward Newton, my executors, administrators, and assigns, or such others
as I, the said William Edward Newton, 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 PRINTING MACHINERY," being a communication
from abroad, upon the condition (amongst others) that I, the said William
Edward Newton, by an instrument in writing under my hand and seal, 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 William Edward Newton, 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 Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
-
The first part of the Invention of "Improvements in Printing Machinery,
and which has been communicated to me by my foreign correspondent as
aforesaid, applies to that description of printing machinery in which the sheets
of paper to be printed are drawn into the machine by the agency of what are
termed feeding
or drop rollers (that is to say), in cases where the sheets are
not fed directly from the feed board to the form, but where the feed board is
terminated by a feeding cylinder carrying a series of belts or endless tapes,
which, in conjunction with another series of tapes, convey the paper between
them to the form, after it has been introduced between them by the said drop
roller, acting in conjunction with the feeding cylinder, upon which the fore-
most edge of the sheet is laid in such a manner as to be seized by the drop
roller falling upon it; and in consequence of the rotary motion of the feeding
cylinder, the sheet is conducted between the aforesaid tapes, when the drop
roller rises, to afford an opportunity to feed another sheet.
It has been customary, heretofore, upon starting the machine, for the feeders
to set the drop rollers in motion by hand, and then to allow them to derive
their impetus from their brief contact with the feeding cylinder, and the result
has been unsatisfactory, inasmuch as, during its elevation or detachment from
the feeding cylinder, its velocity is reduced by natural causes, so that upon

page_text: resuming its contact with the feeding cylinder it has a tendency to retard the
sheet more or less in an increased ratio to the varying speed of the machine,
thereby causing an imperfect register.
.
To obviate this difficulty, the drop roller, according to the present improve-
ments, is at all times to be driven or impelled at a velocity corresponding to
that of certain other parts of the machine, as will be best understood by
reference to the accompanying Drawings, in which Fig. 1 represents a
sectional elevation; and Fig: 2, a corresponding plan of a portion of a type
revolving printing machine.
A is the type cylinder; B and C, impression cylinders at opposite sides of
the type cylinder; D and E are feeding cylinders to the impression cylinders
B and C respectively; F and G are drop rollers; I; I, and J, J, represent
the series of tapes carried by the feeding cylinders; and K, K, and L, L, are
the series of counter tapes, which run in contact with the tapes I, I, and J, J;
M and N are portions of the feed boards on which the paper is placed by the
feeders to a point a little beyond the point of contact between the feeding
cylinders D, E, and the drop rollers F, G, whence it is conducted by them to
the tapes I, K, and J, L, which convey it to the type cylinder or form. The
drop rollers F and G are shewn in their elevated or detached position ready
to receive the sheet of paper. The other position is shewn by dotted lines.
The drop roller F in its elevated position lies in contact with the impelling
roller O, which is driven by contact with the tapes K, K, running with the
same velocity as the surface of the type under all circumstances, and imparting
the same velocity to the drop roller, and as a consequence the sheet is bound
by two rollers, having an equal velocity at their surfaces, and is carried
smoothly and uniformly to the form, thereby ensuring as good a register as if
fed directly to the form by hand from the feed board. The drop roller G is
driven in a similar manner by a series of pullies P, on a shaft running in
contact with the roller H, and occupying the intervening spaces on that roller
between the tapes, the operation and result being similar to the other case.
The second part of the Invention relates to an improved mode of giving
motion to what are termed the fly frames, as at present in use on type revolv-
ing printing machines. As now constructed, the cam shaft that carries the fly
cams of this part of the apparatus, is placed under the centre of the press at
the greatest possible distance from the fly frames, to which it is intended to
give motion by the intervention of geared levers, connecting rods, intermediate
levers, bell cranks, and other complicated contrivances. This mode of trans-
mitting the motion through so many parts is objectionable, in consequence of
the wear and tear of such parts causing play or looseness in the parts severally.

page_text: The whole or accumulated effect of this looseness evinces itself in the inaccurate
operation of the fly frames. Moreover, these connecting rods and some of the
other parts occasion great inconvenience to the pressman, when getting in and
out of the pit underneath the press, to attend to the regulation of the fly cams,
inking apparatus, and other working parts of the machine.
The improvement, which forms the second part of the Invention, will be
apparent upon examining the several Figures in which this part of the machine
is shewn. Fig. 3 is a side elevation of one end of a six cylinder rotary press,
for which I have obtained Letters Patent, shewing the fly frames for the first,
second, and third cylinders, and the improved mode of operating them. Fig. 4
is an end elevation of the same; Fig. 5 is a plan view, shewing all the parts
necessary to a correct understanding of this improvement.
In Fig. 5, A is the cam shaft of the press, and on which the fly cams were
formerly placed. A bevelled wheel B is keyed on its extremity at the rear
side of the press, and transmits its motion through the bevel pinions C, C, to
the longitudinal shafts D, D, and from the wheels E, E, at the end of the
shafts D to the pinions F, F, on the fly cam shafts G, G, at either end of the
press (the shafts D and the bevil wheels may, if desired, be placed within
the framing of the press). The right-hand end of the plan corresponds with.
Figures 3 and 4; H, H, H (Figures 3 and 5), are the fly cams, and they are
of the nature of a wiper. The excentric part elevates the fly frame I, and the
concentric part retains the fly frame in that position while the sheet is passing
down before it, and the termination of the cam allows the fly frame to descend
by the action of the spring K, and lay the sheet on the fly board J. The fly
frame No. 2, in Figures 3 and 4, is raised by the cam H acting on the arm or
crank M, which has a roller L attached to it, which rolls on the periphery of
the cam.
This crank is keyed to a short cross shaft, having a bearing in a
projection on the upright frame, and another crank or lever N is keyed to the
other end of the cross shaft. The crank or lever N is attached by the
connecting rod O to the crank or lever P on the fly frame shaft, and on
the other end of the fly frame shaft is a crank or arm S, attached to a spring
rod and spring K, which tends constantly to force the fly frame I to the
horizontal position, and is opposed by the cam.
The fly frame No. 3 is operated in the same manner, except that the cross
shaft, on which are keyed the cranks or levers M and N, is a little longer, and
has two bearings. Between these bearings is a beam T, which turns on the
cross shaft, and has the roller L attached to one end, and transmits its motion
at the other end to the crank P on the fly frame shaft, No. 1, by means of the
connecting rod R. One long shaft D, and one wheel C, might be used instead

page_text: of the arrangements above described, but from motives of mechanical con-
venience I prefer two separate shafts.
Having now described the Invention of "Improvements in Printing
Machinery," that has been communicated to me by my foreign correspondent,
and having explained the manner of carrying the same into effect, I would
observe, in conclusion, that what I claim as new in the above described
machinery, and desire to secure by Letters Patent, is,―
First, communicating motion to the drop roller in its detached position,
either by contact with the roller O, or otherwise in combination with the tapes
K, K, or with the pullies P and the roller H, or their equivalents, for the
purpose herein described and set forth.
Second, I claim the mode, herein shewn and described, of actuating the fly
cam shaft, and fly frame, or any mere modification thereof, whereby the fly
cam shaft and fly frame may be acted on more directly than heretofore.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Third day of December, in the year of our
Lord One thousand eight hundred and fifty-seven.
