IMPROVEMENTS IN PRINTING MACHINES
Year: 1858

page_text: LETTERS PATENT to Henry Ingle, of Shoe Lane, in the City of London,
Engineer, for the Invention of "IMPROVEMENTS IN PRINTING MACHINES."
aled the 13th July 1858, and dated the 14th January 185
PROVISIONAL SPECIFICATION left by the said Henry Ingle at the
Office of the Commissioners of Patents, with his Petition, on the 14th
January 1858.
I, HENRY INGLE, of Shoe Lane, in the City of London, Engineer, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN PRINTING
MACHINES," to be as follows:-
My Invention consists in imparting the to-and-fro motions to the table:
carrying the types or printing matter from a quadrant in the centre of the
machine, or two quadrants, one on each side of the machine, made to rock,
and connected by steel or other suitable bands or chains to the ends of the
table, and in driving the cylinder or drum carrying the paper by means of a
rack or racks which work into a toothed wheel loose upon the shaft of the
cylinder. Upon the cylinder is a ratchet, which permits of the cylinder and
wheel being driven and moving together when the rack upon the table moves
in one direction, but when going in the contrary direction the wheel only
moves and the-cylinder is fixed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Ingle, in the Great Seal Patent Office on the
14th July 1858.

page_text: WHEREAS Iler most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of January, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Ingle, Her special licence, that I, the said Henry Ingle, my
executors, administrators, and assigns, or such others as I, the said Henry
Ingle, 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 terin 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 MACHINES," upon the condition (amongst others) that I,. the said
Henry Ingle, my executors or administrators, by an instrument 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 Henry Ingle, 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 Invention consists in imparting the to-and-fro motions to the table
carrying the types or printing matter from a sector or quadrant in the centre
of the machine, or two sectors or quadrants, one at each side of the machine,
made to rock, and connected by steel or other suitable bands or chains to the
ends of the table; and in driving the cylinder or drum carrying the paper by
means of a rack or racks which work into a toothed wheel loose upon the
shaft of the cylinder. Upon the cylinder is a ratchet which causes the
cylinder and wheel to move together when the rack upon the table moves in
one direction, but permits the cylinder to remain stationary and moves the
wheel only when going in the contrary direction.
In the Drawings hereunto annexed, Figure 1 shews in side, and Figure 2
in end elevation, the principal parts of a printing machine constructed according
to my Invention.
A is a quadrant, which is centred or works in sockets formed at A' in the
lower part or bed of the frame B of the machine; C is a connecting rod or
lever joined to the quadrant at a, and in connection with the cogged wheel D,

page_text: to which motion is communicated through the pinion E, which is driven in
any convenient manner. Thus as the wheel D revolves a to-and-fro motion
is imparted to the quadrant. Round the quadrant A bands or chains are
passed, which are connected to the ends of the table F for carrying the type
or other printing matter, so that as the quadrant moves it carries with it the
table and parts connected thereto. On the upper part and at one side of the
table there is a rack G into which a toothed wheel H is geared, which is
loose on the shaft I carrying the cylinder or drum K for receiving the paper.
On the inner side of the toothed wheel G (a view of which is given at
Figure 3) there is a notch or stop 6 formed, and to the end of the cylinder K,
seen at Figure 4, which abuts against the wheel G, a ratchet or paul c is
attached, which as the rack and table move in one direction leaves the
cylinder stationary, allowing time for the paper to be placed on; but when
going in the contrary direction the paul enters the notch and causes the
cylinder to move with the toothed wheel, and thus the paper is passed over
the type or printing surface. The table runs on flanged rollers c, c, seen in
Figure 2, and in dotted lines, Figure 1.
Instead of employing bands or chains passing round the quadrant for
imparting motion to the table or type carrier, I sometimes form a rack on the
surface of the quadrant, which gears into teeth formed on the lower part of
the table. Two quadrants may also be employed, one at each side of the
machine.
. And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,―
First, the employment in printing machines of a quadrant or sector or
sectors or quadrants for imparting the to-and-fro motion to the table or type
carriers, essentially as herein-before described.
Secondly, the method of driving the cylinder or drum which carries the
paper by means of a rack or racks in gear with a toothed wheel loose
upon the shaft of the cylinder, in the manner herein-before described, and
illustrated in the Drawings hereunto annexed.
In witness whereof, I, the said Henry Ingle, have hereunto set my
hand and seal, this Fourteenth day of July, One thousand eight
hundred and fifty-eight.
HENRY INGLE. (LS.)
