IMPROVEMENTS IN OR CONNECTED WITH CYLINDER PRINTING MACHINES
Year: 1861

page_text: LETTERS PATENT to William Grove, of 104, Shoe Lane, in the City of
London, Gentleman, for the Invention of "IMPROVEMENTS IN OR CONNECTED
WITH CYLINDER PRINTING MACHINES."
Scaled the 3rd October 1861, and dated the 19th April 1861.
PROVISIONAL SPECIFICATION left by the said William Grove at the
Office of the Commissioners of Patents, with bis Petition, on the
19th April 1861.
I, WILLIAM GROVE, of 104, Shoe Lane, in the City of London, Gentleman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
OR CONNECTED WITH CYLINDER PRINTING MACHINES," to be as follows:-
My improvements in cylinder printing machines refer to the collection or
reception of the sheets of paper after having been printed. My Invention
consists in the employment of a delivery board constructed as hereafter stated,
and placed at an incline behind the lower of two delivery rollers through
which the sheets of paper pass, in combination with a frame carried on the
outer ends of levers pivotted on fixed centres, whereby the position of the
sheets is regulated on to the delivery board. The delivery board is supported
upon or connected to springs in such manner that the paper as it is delivered
depresses the table, and allows of the next sheet or sheets being deposited at
or about the same plane as the preceding sheets, until the delivery board
becomes full, when the printed sheets are removed therefrom, or from time to

page_text: time, as occasion may require, and the table rises to receive a fresh supply,
and descend as before. An adjustable stop is affixed near the lower end of
the table to prevent the sheets falling from it. The frame for directing the
sheets on to the delivery board receives motion through rods and levers from a
cam or eccentric so as to rise and fall as required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Grove in the Great Seal Patent Office on the
19th October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GROVE, of 104, Shoe Lane, in the City of London, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of April, in the year of our Lord.
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Grove, Her special licence that I, the said William
Grove, my executors, administrators, and assigns, or such others as I, the
said William Grove, 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 Inven-
tion for "IMPROVEMENTS IN OR CONNECTED WITH CYLINDER PRINTING MACHINES,"
upon the condition (amongst others) that I, the said William Grove, my
executors or administrators, by an instrument in writing under my, or thoir,
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 Grove, do hereby declare
the nature of my 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say-
My improvements in cylinder printing machines refer to the collection or
reception of the sheets of paper after having been printed.. My Invention

page_text: consists in the employment of a delivery board, constructed as hereafter stated,
and; placed at an incline behind the lower of two delivery rollers through which
the sheets of paper pass, in combination with a frame carried on the outer
ends of levers pivotted on fixed centres, whereby the position of the sheets is
regulated on to the delivery board. The delivery board is supported upon or
connected to springs in such manner that the paper as it is delivered depresses
the table, and allows of the next sheet or sheets being deposited at or about
the same plane as the preceding sheets, until the delivery board becomes full,
when the printed sheets are removed therefrom, or from time to time, as
occasion may require, and the, table rises to receive a fresh supply, and
descends as before. An adjustable stop is affixed near the lower end of the
table to prevent the sheets falling from it. The frame for directing the sheets
on to the delivery board receives motion through rods and levers from a cam
or eccentric, so as to rise and fall as required.
Figure 1 represents so much of an ordinary cylinder printing machine as is
necessary to explain my Invention; Figure 2 is the same in plan, or part of
the same, shewing the drums and driving wheels; Figure 3 is an elevation of
a part of a four-feeder printing machine, known as a "Dryden" machine.
Similar letters refer to similar parts in all the Figures.
ひ
a is the laying-on board, on which the blank paper is placed, and is carried
in the direction of the arrow by the usual means, and is so placed as to be
carried round the drum b; a is the iron bar or frame supporting the laying-on
board (a and are the corresponding laying board and drum on the other.
side, to print two sheets at a time). The blank paper passes over the
drum b, (6), and by means of dropping bars, shewn in Figure 1 by dotted
lines, or by any other usual or well-known mechanical contrivance, such as
grippers or fingers, the sheet is passed along between the tapes d, d, in the
usual manner. The sheets from the drum pass, by the aid of its dropping
bar or other suitable or usual means, along the same tapes d, d, and are passed
on to the impression cylinders (which are not shewn in the Drawing) between
the rollers e, e, and the sheets are returned impressed with the type along or
between the delivery tapes f, f, g, g, being rollers, operating in the usual
manner, carrying the tape, passing over the roller h, through the two delivery
rollers i and . The tapes revolve, and the feeding continues in the usual
manner. When the paper passes through the two delivery rollers it is guided
by the outside or margin tapes, shewn at k, passing over a roller or guide 1.
The sheets as they advance will be disengaged from the margin tapes k by the
open frame m and n. At m is a grip to arrest the progress of the paper when
clear of the delivery rollers i, . The frame is continued, as at n, to draw the

page_text: paper flat down from the margin tape. The frame m is fixed on to the outer
ends of levers pivoted on fixed centres o, and a regular motion is given to the
frame m, working on the pivot o by the connecting rod p, which is in two
pieces, so as to be adjusted to its proper length by means of a left and right-
landed screw and collar, so as to regulate the fall of the frame m, n. This
rod is connected to a bell-crank lever q, "and is worked by the heart wheel
or cam r, or other suitable contrivance, which is connected on to the drum
spindle, by which a regular motion is given to the frame m, n, on the delivery
of each sheet from the delivery rollers i, ¹. When the paper has been passed
along the margin tapes k, and is disengaged by the frame m, n, it is delivered
on the delivery or receiving board s. As the paper is delivered on the board
it will accumulate, and may be removed from time to time, as inay be con-
venient; and in order to avoid the necessity of a frequent renewal of the
paper I furnish the said delivery or [receiving board with springs on the under
side, in such a manner that the paper as it is delivered depresses the table or
delivery board, so as to allow space for the next sheet or sheets being deposited
at or about the same plane as the preceding sheets, until the delivery board
becomes full. I have shewn on the Drawings, Figures 1 and 3, the said
springs t, t, but I do not desire to limit myself to springs alone; any other
apparatus producing a similar effect may be adopted.
Figure 3 represents an elevation of a part of a four-feeder printing machine,
known as a "Dryden" machine, as aforesaid, but I dispense with the extra
delivery board usually used on such machines, using one on each end of the
ínachine. Figure 8 s shews one of such delivery boards. The sheet will be
carried along the delivery tapes passing over the roller q, Figure 8, and will
be brought up to 92 by a clip or other well-known mechanical means for turning
sheets, and will pass down f' through the delivery rollers i, i¹, and will pass
along the margin tapes kas before described, and deliver the sheets on to the
receiving board, the frame m, n, operating to disengage the sheet from the
guiding or margin tapes as before described. x is the pinion for regulating
the time or movement of the cam. The connecting rod works at each end in
slots to give an extra action if required. y, Figure 2, is a part of the frame
holding the driving apparatus, and carries the bevel wheels, 2, which give
motion to the drum. The colored parts are those which relate to my
improvements, or those connected therewith. An adjustable stop is affixed
near the lower end of the table to prevent the sheets sliding down or falling
from it.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I declare that I do not desire to bind

page_text: myself to the use of the particular details, provided the main features of my
Invention be retained, and although I have described the said apparatus as
applied to the particular machines described, the same apparatus may be
applied to all cylinder printing machines, and that I claim the employment
of the delivery board, as before described, in combination with the frame or
apparatus herein-before described for placing the printed sheets on the said
delivery board, substantially in manner herein-before described.
In witness whereof, I, the said William Grove, have hereunto set my
hand and seal, this Nineteenth day of October, One thousand eight
hundred and sixty-one.
WILLIAM GROVE. (L.S.)
