Invention of "IMPROVEMENTS IN PRINTING MACHINERY."-A communication
from abroad by Richard March Hoe, of New York, in the United States
of America.
Sealed the 25th April 1865, and dated the 16th November 1864.
PROVISIONAL SPECIFICATION left by the said William Edward Newton,
at the Office of the Commissioners of Patents, with his Petition, on
the 16th November 1864.
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 to certain
improved mechanical arrangements for delivering the printed sheets from the
impression cylinders and depositing them in pile on tables provided for the
purpose.
The Invention is more particularly applicable to the fast printing machines
in which a large number of sheets are required to be delivered in rapid
succession with little or no space or interval between the end of one sheet
and the commencement of the succeeding sheet.
The main feature of novelty consists in adapting to every pair of delivery
rollers two or more sets of carrying tapes and rollers with the requisite fly

page_text: frames and tables to receive the printed sheets, which, as they are taken in
rapid succession from the impression cylinders by the delivery rollers, are fed
alternately into the grip of one of two sets of carrying tapes and rollers, so
that first one set of tapes and then the other may receive a printed sheet and
have time to deposit it on the table.
The mechanical arrangements whereby this feeding of the printed sheets
alternately to one or other of two sets of carrying tapes and rollers may be
effected, may be varied. I do not therefore intend to confine myself to any
particular form of apparatus whereby the result may be obtained, but I will
explain as examples some three or four arrangements that will effect the
object. For instance, two sets of carrying tapes and rollers are to be placed
one above the other and as near together as possible. Both sets are mounted
in a vibrating frame so that they may be moved up or down in a vertical
direction, in order to bring the nip of first one set of tapes and then of the
other opposite to the bite of the delivery rollers. A guide bar placed between
the delivery rollers and the carrying tapes directs the issuing edge of the
printed sheets, first to one set of tapes and then to the other. In this way
each set of carrying tapes will only have one half of the printed sheets to
dispose of, and will consequently have ample time to deposit them on the table
by means of the fly frames as is well known.
An obvious modification of this arrangement is to mount the rollers and
pullies of the carrying tapes in a stationary frame, and to move the delivery
rollers up and down so as to bring them alternately opposite to the grip of the
sets of carrying tapes in order that the printed sheets as they issue from
between the delivery rollers may be delivered first to one set of tapes and
then to the other.
According to another arrangement the edge of the printed sheets' as they
issue from the delivery rollers are blown by means of an intermittent blast
from air pipes into the grip of first one and then the other set of carrying
tapes. To this end there are two horizontal air pipes placed one above the
other near the grip of the delivery rollers, and these pipes are provided with
cocks which are operated at the proper moment by means of suitable
mechanism adapted to any convenient part of the machine. The under one
of these pipes is perforated with holes on the top side, and the other one on
the bottom side, and as the printed sheets pass between them it will be under-
stood that by allowing a blast of air to issue from one or other of these pipes
alternately the sheets may be blown either up or down, and thereby directed
into the grip of either the top or bottom set of carrying tapes as the case may
be. The blast of air required for this arrangement may either be obtained

page_text: from a reservoir of compressed air conveniently placed for the purpose, or
some of the working parts of the machine may be made to act on an air pump
or bellows, and thus force air through the perforated pipes.
Another mode of directing the printed sheets alternately to the upper and
under set of carrying tapes consists in the employment of a vibrating or
oscillating directing bar which is placed opposite to the nip of the delivery
rollers, and as it oscillates on its centre of motion it will direct the sheets either
up or down as may be required. The fly frames which receive the printed
sheets from the carrying tapes and deposit them on the tables are of the kind
usually employed in Hoe's circular bed rotary printing machine, and therefore,
require no description.
It will be obvious that more than two sets of carrying tapes and rollers may
if desired be adapted to each pair of delivery rollers, and also that two more
or second sets of carrying tapes and rollers may be adapted. to each of the
original sets of carrying tapes, so that the total number of printed sheets that
issue from each pair of delivery rollers may be subdivided a second time and
formed into four separate piles which will be formed by the fly frames in the
ordinary manner.
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 16th May 1865.

Man, an Invention for "IMPROVEMENTS IN PRINTING MACHINERY," being a com-
munication from abroad, upon the condition (amongst others) that I, the
said William Edward Newton, my executors or administrators, by an instru-
ment in writing 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 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): :-
This Invention of "Improvements in Printing Machinery" relates to
certain improved mechanical arrangements for delivering the printed sheets
from the impression cylinders, and depositing them in piles on tables provided
for the purpose.
The Invention is more particularly applicable to the fast printing machines
known as Hoe's rotary circular bed printing machines, but it may also be
advantageously adapted to other printing machines in which a large number
of sheets are required to be delivered in rapid succession with little or no
space or interval between the end of one sheet and the commencement of the
succeeding sheet.
The main feature of novelty in the present Invention consists in adapting to
every pair of delivery rollers two or more sets of carrying tapes and rollers
with the requisite fly frames and tables to receive the printed sheets, which,
as they are taken in rapid succession from the impression cylinders by the
delivery rollers, are fed alternately into the grip of one of two or more sets of
carrying tapes and rollers, so that first one set of tapes and then the other
may receive a printed sheet, and have time to deposit it on the table.
The mechanical arrangements whereby this feeding of the printed sheets
alternately to one or other of two sets of carrying tapés and rollers may be
effected may be varied. I do not therefore intend to confine myself to any
particular form of apparatus whereby the result may be obtained.
In the accompanying Drawings I have shewn as examples three arrange-
ments that will effect the object. Fig. 1 represents in elevation an
arrangement in which two sets of carrying tapes a, a, a, a, and rollers a', a¹,
a', a', are to be placed one above the other, and as near together as possible.
Both sets are mounted in a vibrating frame 6 which moves on a centre pin 6¹,

page_text: fixed in the stationary framing. By this arrangement the carrying tapes and
rollers a, a, may be moved up or down in a vertical direction, as indicated by
dotted lines in the Drawing, in order to bring the nip of first one set of tapes
and then of the other opposite to the bite of the delivery rollers c, c.
A guide
bar d, placed between the delivery rollers and the carrying tapes, directs the
issuing edge of the printed sheets first to one set of tapes and then to the
other. In this way each set of carrying tapes will only have one half of the
printed sheets to dispose of, and will consequently have ample time to deposit
them on the table by means of the fly frames as is well known.
An obvious modification of this arrangement is to mount the rollers and
pullies a¹ of the carrying tapes a, in a stationary frame, and to move the
delivery rollers c, c, up and down so as to bring them alternately opposite to
the grip of the sets of carrying tapes a, a, in order that the printed sheets as
they issue from between the delivery rollers c may be delivered first to one set
of tapes and then to the other, and conveyed by them to the fly frames e, e,
whereby the printed sheets are deposited on the tables f, f.
Fig. 2 represents in elevation another arrangement in which the forward
edges of the printed sheets as they issue from the delivery rollers c, c, are
blown by means of an intermittent blast from the air pipes g; g', into the grip
of or against first one and then against the other set of carrying tapes a, a.
To this end there are two horizontal air pipes g. 9', placed one above the
other below near the grip of the delivery rollers c, c. These pipes com-
municate with two vertical air pipes 9, 9%, which are connected with two
pumps n, n, as seen in the detached view, Fig. 2, for the purpose of letting
on the air to the pipes 9, 9', alternately. These pumps n are-operated at the
proper moment by means of a pair of excentrics o, o¹, on the bevil wheel
shaft p, as shewn in the Figures. The under one of these pipes g¹ is per-
forated with holes on the top side, and the other one 9 on the bottom side,
and as the printed sheets pass between them a blast of air is caused to issue
from the holes in one or other of these pipes alternately, so that the sheets
will be blown either up or down, and thereby directed into the grip of or
against either the top or bottom set of carrying tapes a, a, as the case may be,
as shewn by red lines in the Figure. The blast of air required for this
arrangement may, if desired, be obtained from a reservoir of compressed air
conveniently placed for the purpose, or the cranks or excentrics o, o¹, on the
shaft p may be made to act on bellows or on the air pumps as at n, and thus
force and compress air into the pipes 9³, or into a compressed air reservoir,
from whence it will pass through the pipes 93, 9³, into the perforated pipes g, g².
Another mode of directing the printed sheets alternately to the upper and

page_text: under set of carrying tapes is shewn at Fig. 3, and consists in the employment
of the vibrating or oscillating direction bar h, which is placed opposite to the
nip of the delivery rollers c, c, and as it oscillates on its centre of motion it
will direct the sheets either to the right or to the left as may be required.
The oscillating directing bar h is actuated by means of a rod i connected to a
weighted lever j, which is operated by a cam on the shaft k. The fly frames e
which receive the printed sheets from the carrying tapes a, a, and deposit
them on the tables, are of the kind usually employed in Hoe's circular bed
rotary printing machine, and therefore require no description further than to
say that they are actuated by the cams 1, 1, which are rotated by means of the
bevil gear shewn in the Drawings, or by any other convenient mechanism
connected with the working parts of the machine.
It will be obvious that more than two sets of carrying tapes and rollers a, a,
a¹³, a', may, if desired, be adapted to each pair of delivery rollers c, c, in all
the arrangements described, and also that two or more second sets of carrying
tapes and rollers may be adapted to each of the original sets of carrying tapes
a, a, so that the total number of printed sheets that issue from each pair of
delivery rollers c, c, may be subdivided a second time, and formed into four
separate piles, which will be formed by the fly frames e', e', in the ordinary
manner.
Having now described this Invention of improvements in printing machinery,
and having explained the manner of carrying the same into effect, I claim as
the Invention secured to me by Letters Patent as aforesaid the adaptation to
the delivery rollers of fast printing machinery of two or more sets of
conducting tapes and rollers for the purpose of carrying away and con-
ducting the printed sheets to separate fly frames and tables as herein set
forth.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, this Twelfth day of May, in the year of our
Lord One thousand eight hundred and sixty-five.
