IMPROVEMENTS IN INKING APPARATUS FOR BLOCKING AND PRINTING PRESSES "
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We WALTER ALLEN, of 37, Percival Street, Clerkenwell, in the County of
Middlesex, Engineer, and CHARLES WOLFE, of 43, Whiskin Street, Clerkenwell, in
the same County, Engineer, do hereby declare the nature of our Invention for
IMPROVEMENTS IN INKING APPARATUS FOR BLOCKING AND PRINTING PRESSES " to
be as follows:-
This Invention relates to improvements in inking apparatus for blocking and
printing presses, especial objects of the Invention being to dispense with the use of
continually re-inking the inking table by hand after every few impressions taken
and to readily and effectually keep a better and more even supply of ink upon the
inking table.
For this purpose we arrange suitable roller carriages having slots cut in them
in which the spindles on which the inking rollers run are placed and which may be
caused to move along the arms suitably fastened to the sides of and running
parallel with the table on which the book-covers or other article to be blocked or
printed is placed and retained in any required position by a screw or other suitable
means. Above the slot in which the spindles are placed we fasten a washer or
other suitable piece to prevent the spindles from jumping out when the machine is
in operation.
Brackets may be adapted and suitably fastened to the sides of the ribs of the
machine to which is fastened the inking table the height of which is adjusted by
means of thumb or other screws as hitherto.
To the end of the inking table we secure by screws or other means (in any
suitable or convenient manner) a duct, which may contain ink or one or more
suitable coloring matters and preferably in the front thereof we arrange a duct
roller (made of any suitable metal) which is caused to revolve by means of a
ratchet wheel fixed upon the end thereof and which is actuated by means of a paul
working on a stud which can be moved up and down in a slot in the end of one of
the arms so as to allow the paul to take one or more teeth on the ratchet wheel.
The duct roller carries the ink round with it and in the action of working the
table and connections, the distributing rollers working in the carriages suitably
fixed upon the arms carry the ink from the duct roller on to the inking table from
which it is carried by other rollers on to the block in the ordinary manner.

page_text: There may also be arranged one or more reciprocating rollers to more evenly
spread the ink on the inking table.
By the arrangement herein before described the mere act of pulling the table and
connections by a handle fixed at the side away from the press the inking table and
block are re-inked and by the act of pushing the table and connections with the
book-cover or other article to be blocked or printed on it the duct roller is caused
to move partly round and present a fresh supply of ink for the inking rollers to
again ink the inking table and block.
This inking apparatus may also be applied to blocking and printing presses
driven by machinery.

page_text: We, WALTER ALLEN, Engineer, of 37, Percival Street, Clerkenwell, in the
County of Middlesex, and CHARLES WOLFE, Engineer, of 43, Whiskin Street,
Clerkenwell, in the same County, do hereby declare the nature of our Invention for
"IMPROVEMENTS IN INKING APPARATUS FOR BLOCKING AND PRINTING PRESSES "
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
This Invention relates to improvements in inking apparatus for blocking and
printing presses, especial objects of the Invention being to dispense with the use of
continually re-inking the inking table by hand after every few impressions taken
from the block, thereby saving time and labor, and effectually keeping a better and
more even supply of ink thereon.
On the accompanying drawings Fig; 1, represents a plan view of the improved
inking apparatus adapted to an ordinary blocking press such as are now in common
use, the upper part of which is not shown.
Fig; 2, represents a side view of the same along the line a-b.
Figs; 3, and 4, respectively represent a plan and front view of a roller carriage.
In carrying the Invention into practical effect movable roller carriages are
arranged along arms, 14, having slots, 1, cut in them, in which the spindles, 2, on
which the inking rollers, 3, 4, 5, 6, 7, run are placed and above which slots washers, 8,
or equivalent pieces are placed, which when turned round as shown in Fig; 3,
permit of the removal of the said rollers for repairs or otherwise. These washers, 8,
are kept in position as shown in Fig; 1, by lock nuts, 9, on bolts, 10, and thus
prevent the inking rollers from jumping out when the machine is being worked.
13, represents a key piece which may be inserted between the arms, 14, and the
roller carriage for firmly holding it in position when the bolt, 10, is turned.
The rollers, 3, 4, 5, 6, 7, may be adjusted to the required height by means of
screws, 11, and kept in such positions by lock nuts, 12.
The arms, 14, are secured to the table, 15, by screws or other means and may be
made of any required length, according to the number of rollers intended to be
used in the machine, and may be kept at the proper distance apart at the ends by
a stretcher bar, 17, near which an upright piece or bracket, 18, is fastened-having a
movable stud, 19, projecting therefrom which works in the slot, 20, On this
stud, 19, works a paul, 16, which is arrested in its backward movement by the
pin, 21. A duct, 22, for containing ink or one or more coloring matters is secured
to the end of the inking table, 23, by bolts or other means, and in the front thereof
we arrange in bearings, 23*, a duct roller, 24, made of iron or other suitable metal
on the end of the spindle of which a ratchet wheel, 25, is fixed or secured which
may have any number of teeth in it. The inking table, 23, is supported and
adjusted to the required height by screws, 27, working through brackets, 28, (which
are secured to the sides of the ribs of the machine by screws or bolts) and is kept
in such position by lock nuts, 29.
When the machine is worked the operation of pushing the table, 15, by means
of the handles, 26, under the block-(which is not shown) to block say a book cover
causes the paul 16, to come into contact with and move the ratchet wheel, 25,
partly round, thereby causing the duct roller 24, also to partly revolve and present
a fresh supply of ink which is taken therefrom by the roller, 7; and in the operation
of pulling the table, 15, by the said handle from under the block, the ink is carried
on to the inking table, 23, by the roller, 7, and the block is re-inked by the
rollers, 3, 4, which have taken a fresh supply of ink from the inking table.

page_text: In both of the aforesaid operations the reciprocating rollers, 5, 6, spread the ink
on the inking table, 23, so that an even supply is maintained at all parts of the
said table.
The duct roller, 24, may be caused to move either one or more teeth forward at
each operation of blocking say a book cover, by the adjustment of the movable
stud, 19, in the slot, 20, and by this means the supply of ink can be regulated by
the attendant to suit the work being done.
This arrangement of inking apparatus is also applicable to blocking and printing
presses driven by steam or other power.
We wish it to be understood that we do not confine ourselves to the means for
actuating the duct roller, as this may be effected by other means than that shown
and described, and the duct may be placed above or below, or in any other
convenient position; nor do we confine ourselves to the number of inking rollers
used as this is not material to the Invention, as we may when required dispense
with the rollers, 5, 6, 7, though they are preferably used when the improvements
are adapted to printing presses.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. The combination with blocking and printing presses of the duct 22, duct
roller, 24, ratchet wheel, 25, and movable paul, 16, or other equivalent means for
actuating the said duct roller and re-inking the inking tablo, 23, when the machine
is is operation.
2. The combination with blocking and printing presses of adjustable roller
carriages having washers, 3, which when in the position shown in Fig; 1, prevent
the inking rollers from jumping out of the slots, 1, when the machine is in
operation, and when turned round as shown in Fig; 3, permit of the removal of
such inking rollers for repairs or otherwise, and with screws and lock nuts for
securing such roller carriages in the position required along the arms, 9, holding
the washers, 8, over the slots, 1, and adjusting the height of the inking rollers,
substantially as herein before described with reference to the accompanying
drawings.
Dated this 16th day of January 1885.
