& Co Patent Agents Southampton Buildings London for an Invention
of "IMPROVEMENTS IN INK-DISTRIBUTING APPARATUS FOR PRINTING PRESSES
Communicated to him from abroad by Augustus Sidney Doane, of the City
and State of New York, United States of America
PROVISIONAL SPECIFICATION left by the said William Robert Lake at
the Office of the Commissioners of Patents on the 11th July 1882.
WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co., Patent
Agents, Southampton Buildings, London. "IMPROVEMENTS -IN INK-DISTRIBUTING
APPARATUS FOR PRINTING PRESSES." [A communication to him from abroad by
Augustus Sidney Doane, of the City and State of New York, United States of
America]
This Invention relates to improvements in ink distributing apparatus to be used
in job printing presses and comprises an oblong square slab or plate placed at the
rear of and above the bed of the press and supported upon a cross plate elevated
sufficiently above the said bed to allow the form inking rollers to be passed up and
down over the slab or plate to receive their supply of ink therefrom which
supply of ink the said rollers impart to the form or types secured upon the bed.
At the extreme upper end of the slab or plate is placed an ink fountain
constructed in the usual manner.
"
Upon each side of the said plate or slab I arrange in such a manner that they
may be free to move up and down upon the same, grooved slides or a carriage
intended to receive and carry in grooved portions a 'messenger ." roller and in
advance of this messenger roller I arrange any desired number of rollers arranged
at an angle, for being generally employed.
These rollers are placed angularly so that they may have a vibratory movement
imparted to them in travelling up and down over the slab or plate.

page_text: Links or connecting levers pass about centrally from the groove slides on the
carriage to the roller arms or supports for the form inking rollers so that as motion
is communicated to the roller arms it will in turn be communicated to the carriage
and thus the vibrators and messenger roller are caused to move up and down over
the slab or plate.
In some cases, in addition to the vibrators, I employ what are termed "rider
rollers" or rollers placed between and above or over each pair of vibrators.
The said messenger rollers and vibrators are covered with the ordinary compo-
sition used by printers to form inking rollers. The rider rollers may be covered
in a similar manner or may be plain cylinders of wood or iron or iron or wood
covered with cloth or other fabric.
In addition to perfect control of the ink the full form in the chase can be covered
and therefore a heavier or larger form can be worked without straining the
machine, and the impression being light on back, no dry pressing of the printed
sheets is required.
My improvements may be used in any form of job printing press wherein a disc
is employed for distributing the ink.

by the said William Robert Lake in the Great Seal Patent Office on the
10th January 1883.
WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co., Patent
Agents, Southampton Buildings, London, IMPROVEMENTS IN INK-DISTRIBUTING
APPARATUS FOR PRINTING PRESSES." A communication to me from abroad by
Augustus Sidney Doane, of the City and State of New York, United States of
America.
This invention relates to improvements in ink-distributing apparatus to be
used in job printing presses, and comprises an oblong slab or plate placed at the
rear of, and above, the bed of the press, and supported upon a cross plate elevated
sufficiently above the said bed to allow the form inking rollers to be passed up and
down over the slab or plate to receive a supply of ink therefrom, which supply of
ink the said rollers impart to the form or type secured upon the bed. At the
extreme upper end of the slab or plate is placed an ink-fountain constructed in the
usual manner.
Upon each side of the said plate or slab I arrange, in such a manner that they
may be free to move up and down upon the same, grooved slides, or a carriage,
intended to receive and carry in grooved portions a Messenger" roller, and in
advance of this messenger roller I arrange any desired number of rollers placed at
an angle, four being generally employed. These rollers are placed angularly so
that they may have a vibratory movement imparted to them in travelling up and
down over the slab or plate. Connecting levers pass about centrally from the
grooved slides on the carriage to the roller arms or supports for the form inking
rollers, so that, as motion is communicated to the roller arms it will in turn be
communicated to the carriage, and thus the vibrators and messenger-roller are
caused to move up and down over the slab or plate.
In some cases, in addition to the vibrators, I employ what are termed "rider
rollers" or rollers placed between and above or over each pair of vibrators. The
said messenger roller and vibrators are covered with the ordinary composition used
by printers to form inking rollers. The rider rollers may be covered in a similar
manner or may be plain cylinders of wood, iron or iron and wood covered with
cloth or other fabric.
In addition to perfect control of the ink the full form in the chase can be
covered, and therefore a heavier or larger form can be worked without straining
the machine, and the impression being light on the back, no dry pressing of the
printed sheets is required.
My improvements may be used in any form of job printing press wherein rocking
roller-arms are employed for distributing the ink.
In the accompanying drawing
Figure 1 is a side view of a job printing press having the improved distribution
roller attached, the messenger roller being represented as receiving a supply of
ink from the ink-fountain and the form inking rollers receiving their supply of
ink from the slab or table.
Figure 2, is a similar view showing the form inking rollers after they have passed
over the form and the vibrators after they have travelled over the slab or table
followed by the messenger roller
Figure 3, is a plan of the distribution rollers as shown in Figure 1.

page_text: Figure 5 is a sectional side view of the fountain showing the means for operating
the duct roller of the fountain.
Figure 6 is a section of the fountain showing the knife and one of its regulating
screws.
Figure 7 is a top view or plan of a portion of the ink-fountain, messenger
roller, and ink slab or table.
After the fountain lias been charged with ink which is to be supplied to the
slab or table, its flow is regulated or the quantity to be supplied is governed, by
the regulating screws, Figure 6, which bring the knife of the fountain closer to, or
farther away from, the duct roller; this duct roller is caused to rotate by means
of the pawl and ratchet wheel Figures 5 and 7, the ratchet wheel being attached
on one end of the duct roller, and the pawl being operated by the strap or cord
connected to one of the roller arms forming the roller carriage. As the sliding
carriage connected by the links to the rocking roller arms is moved back on the
slab or table, the messenger-roller receives a supply of ink from the duct-roller of
the fountain and places it upon the slab or table, so that on the succeeding return
movement of the carriage; the vibrators will thoroughly distribute upon the slab or
table the ink to be imparted to the form rollers before they descend to ink the
form of type.
Having thus fully described the said Invention as communicated to me by my s
Foreign correspondent, and the manner of performing the same, I wish it under-
stood that I claim.
The combination, with the roller carriage, carrying the form inking rollers, of a
slab or table, the sliding carriage in which are received two or more vibrating
rollers, a messenger roller, and an ink fountain, and with or without one or more
rider rollers placed above, or between, the said vibrating rollers.
In Witness whereof I the said William Robert Lake, have hereunto set my
hand and seal this Ninth day of January in the year of our Lord One
thousand eight hundred and eighty three.
