Improvements in or relating to the Ink Ducts or Fountains of
Printing Machinery for Multi-colour or other Printing.
I, FRANCIS CORNWALL TAYLOR, of 2095, Lexington Avenue, in the City,
County, and State of New York, United States of America, and of 19, Bucking-
ham Street, Strand, London, Printer, do hereby declare the nature of this
invention to be as follows:
-
This invention relates to the ink ducts or fountains of printing machines and
is primarily designed for use in multi-colour printing where several colours or
tones are printed at one impression although applicable to ordinary or mono-
colour printing.
In Letters Patent No. 8748 of 1896 is described mechanism for sub-dividing
the ink duct or ink trough or fountain into a number of compartments the
number and size of each of which can (to a certain extent) be altered as therein
specified.
Now according to my present invention instead of using the arrangement of
mechanism shown in the aforesaid patent I now use an ordinary solid or con-
tinuous duct roller or fountain roller or any other suitable roller or equivalent
and I form a number of separate and independent divisions or partitions of special
construction for dividing the duct or fountain into as many compartments as
desired and of any size or sizes and so as to obtain a better, easier, and much
finer adjustment.
Now these divisions or partitions I construct of one, two or more plates or
cheeks of rigid material advantageously a metal non-corrodible with ink and in
conjunction with these I insert or use any suitable elastic flexible or pliable
material or packing such as a sheet or sheets of india-rubber or equivalent which
advantageously extend a little beyond the rigid plates or cheeks to form a pack-
ing for preventing escape of the ink between said packing and the surface same
bears against for instance I may advantageously use two rigid plates or side
cheeks with the elastic or other insertion between same being secured together
in any suitable manner.
These independent partitions or divisions are each shaped at one part or edge
to correspond with or as a counter-part to the bottom etc. of the ink duct or ink
fountain and also at another part or edge as a counterpart to partly encircle the
fountain roller or ink duct roller so that when pressed firmly against said duct
and roller--as hereinafter described-the aforesaid packing makes an ink-tight
joint therewith.
Now in order to permit these or equivalent divisions or partitions to be respec
tively mounted at any point or points in the length of the ink-duct or fountain
and at various distances from one another I use a longitudinal rod or bar (or
two or more of same) extending over the ink-duct i.e. over these divisions or
partitions (which latter would be of equal sizes) and in order to individually

page_text: on or
to
grip and hold or control each of the several divisions or partitions and prevent
lateral movement thereof I form the underside of said rod or bar (or bars) as a
rack or equivalent such for instance as a series of forks therein or slots therein
transverse to the length of said bar or downwardly projecting pins or screws
may be used whereby the upper edge of each said partition or division is sup-
ported and held firmly in any desired position said bar or bars being mounted
in any suitable supports and provided with suitable means
force same downwards or otherwise tighten said bar or bars upon the
edges of the partitions or better still (and in order to obtain a finer adjustment
than would be possible with the aforesaid rack) I may use a slotted plate bar or
bars formed or mounted on the fixed frame of the machine (or two or more bars
forming a slot between them) so that one or more slots or edges are provided
over or adjacent to the ink duct and I provide a set screw or other suitable and
independent means adapted to slide along in said slot or on said edge and be
tightened therein or thereon upon each said division or partition respectively
for instance a number of grooved sliding blocks or grips may be used provided
with a set screw or means to fix same in any desired position (or other suitablo
clamps may be used) in said slot or on said bar or plate said screw or equivalent
screwing through said slide blocks which are tapped for this purpose and to the
lower end of this screw or the like is swivelled or otherwise suitably attached a
fork or device adapted to embrace the edge of one of the aforesaid divisions or
partitions (or said fork or device for embracing the said partition may be suitably
attached to the underside of the block) or said divisions or partitions may each be
formed or provided with an extension or attachment adapted to slide in or
operate in conjunction with said slot so that each of the partitions or divisions
may be thus independently adjusted by sliding same along in said slot to-or
otherwise placing same in-the exact position desired and then rigidly fixing
same by the above or other suitable means (for instance if desired I may provide
each said partition or division with a screw clamp or the like independent means
adapted to slide on or fit over the edge of a plate or bar and be clamped or
screwed or otherwise rigidly attached thereto at any desired position) whereby
the packing of the said divisions or partitions will be compressed against or
firmly pressed upon the bottom etc. of the ink duct or fountain and also against
the fountain roller and thus any number and width of separate ink-tight com-
partments are formed by very simple and inexpensive means capable of being
easily and most exactly adjusted when required.

Improvements in or relating to the Ink Ducts or Fountains of
Printing Machinery for Multi-colour or other Printing..
I, FRANCIS CORNWALL TAYLOR, of 2095, Lexington Avenue, in the City,
County, and State of New York, United States of America, and of 19, Bucking-
ham Street, Strand, London, Printer, do hereby declare the nature of this
invention 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 the ink ducts or fountains of printing machines and

page_text: is primarily designed for use in multi-colour printing where several colours or
tones are printed at one impression although applicable to ordinary or mono-
colour printing.
In Letters Patent No. 8748 of 1896 is described mechanism for sub-dividing
the ink duct or ink trough or fountain into a number of compartments the
number and size of each of which can (to a certain extent) be altered as therein
specified.
Now according to my present invention instead of using the arrangement of
mechanism shown in the aforesaid patent I now use an ordinary solid or con-
tinuous duct roller or fountain roller or any other suitable roller or equivalent
and I form a number of separate and independent divisions or partitions of special
construction for dividing the duct or fountain into as many compartments as
desired and of any size or sizes with means to independently adjust each said
partition whereby I obtain a better, easier, and much finer adjustment. Now
these divisions or partitions I construct of two (or more) plates or cheeks of
rigid material advantageously a metal non-corrodible with ink and in conjunc-
tion with these I insert or use between same any suitable elastic flexible or pliable
material or packing such as a sheet or sheets of india-rubber or equivalent which
advantageously extends a little beyond the rigid plates or cheeks (on those edges
which bear against the duct and duct roller) to form a packing for preventing
escape of the ink between said packing and the surface same bears against
the two rigid plates with the elastic or other insertion between same being secured
together in any suitable manner.
These independent partitions or divisions are each shaped at one part or edge
to correspond with or as a counter-part to the bottom etc. of the ink duct or ink
fountain and also at another part or edge as a counterpart to partly encircle the
fountain roller or ink duct roller so that when pressed firmly against said duct
and roller-as hereinafter described the aforesaid packing makes an ink-tight
joint therewith.
Now in order to permit these or equivalent divisions or partitions to be respec-
tively mounted at any point or points in the length of the ink-duct or fountain
and to be accurately adjusted at various distances from one another and in order
to individually grip and hold or control each of the several divisions or partitions
and prevent lateral movement thereof I use a longitudinal rod or bar (or two or
more of same) or frame extending over the ink-duct i.e. over these divisions or
partitions (which latter would be of equal size) said bar or bars being mounted
on or in any suitable supports and provided with suitable means to force same
downwards or otherwise tighten said bar or bars upon the edges of the partitions
or I may use a slotted plate bar or bars formed or mounted on the fixed frame
of the machine or two or more bars forming a slot between them so that one or
more slots or edges are provided over or adjacent to the ink duct and I provide
a set screw (for each partition) or other suitable and independent means
(for each partition) adapted to slide along in said slot or on said edge
or edges and be tightened therein or thereon upon its said division or partition
for instance a number of grooved sliding blocks or grips may be used provided
with a set screw or means to fix same in any desired position (or other suitable
clamps may be used) in said slot or on said bar or plate said screw or equivalent
screwing through said slide blocks which are tapped for this purpose and to the
lower part or underside of this set screw or the like is swivelled or otherwise
suitably attached a fork or device adapted to embrace the edge of one of the afore-
said divisions or partitions (or said fork or device for embracing the said partition
may be suitably attached to the underside of the block) or said divisions or
partitions may each be formed or provided with an extension or attachment
adapted to slide in or operate in conjunction with said slot so that each of the
partitions or divisions may be thus independently adjusted by sliding same along
in said slot to or otherwise placing same in-the exact position desired and then
rigidly fixing same by the above or other suitable means (for instance if desired
I may provide each said partition or division with a screw clamp or the like

page_text: independent means adapted to slide on or fit over the edge of a plate or bar and
be clamped or screwed or otherwise rigidly attached thereto at any desired
position) whereby the packing of the said divisions or partitions will be com-
pressed against or firmly pressed upon the bottom etc. of the ink duct or fountain
and also against the fountain roller and thus any number and width of separate
ink-tight compartments are formed by very simple and inexpensive means
capable of being easily and most exactly adjusted when required.
In the accompanying drawings I have illustrated my invention carried into
practice with slide blocks each having a set screw passing therethrough and
swivelled to a forked device adapted to embrace the upper edge of a division or
partition whereby the latter can be independently adjusted and fixed at any
desired position in the ink trough.
Referring to the drawings:-
Fig. 1 is a plan view of an ink duct with a number of divisions or partitions
therein and means to adjust the latter in position in the ink duct according to my
present invention.
Fig. 2 is a cross sectional view on line 2-2 Fig. 1.
Fig. 3 is a local perspective view on an enlarged scale showing in detail the
means for adjusting and fixing the division or partition.
a is the sloping bottom of the ink duct or trough same being made if desired
capable of adjustment towards and away from the duct roller 6 by means of the
adjusting screws a screwed through the frame of the machine.
6 is a continuous (i.e. non-divided) duct roller or fountain roller of any well-
known or suitable construction--this roller b and the part a thus forming an ink
trough same being old and constituting no part separately of my present inven-
tion.
cc are the divisions or partitions same being formed as shown of two sheets
or plates of metal non-corrodible by ink and enclosing between them a thin sheet
of india-rubber which latter projects slightly beyond the edge c¹ which is
curved to the radius of the roller and also slightly beyond the edge which fits
against the bottom a of the ink trough.
is slot in the slotted plate d* fixed to or carried by or formed on the fixed frame a
in any suitable manner and extending over the ink trough and parallel there-
with this frame or slotted bar d being open at one end d see Fig. 1 so as
to permit the introduction in said slot between the projecting edges dd of the
slide blocks f which have grooves f¹ f2 formed therein of corresponding shape to
the edges did see Fig. 3.
9 is the set screw which screws into and through the block f (the latter being
tapped for this purpose) this screw 9 being provided with any suitable means to
revolve same such as the square head g¹ at the top end, while the lower end of
said screw is swivelled to the fork or saddle piece h which latter is of a width
to receive therein between the division or partition c which it embraces and sup-
ports on both sides as shown in the drawings.
A separate slide block f with its set screw g and fork his provided for each
division or partition & the number of the latter varying according to the number
of compartments into which it is desired to divide the ink trough.
It will thus readily be seen that each division or partition c embraced and sup-
ported by its saddle piece or fork h carried on the slide block f can be moved
laterally along the ink trough to the exact position required and there fixed in
position by means of the set screw 9 which is tightened up so that an ink-tight
joint is made between the edge c¹ and the duct roller b and the edge 3 of the
bottom of the trough a and thus the most accurate adjustment of each of the
divisions or partitions c can be obtained.
care rivets or screws (or other suitable fasteners) which are passed right
through the two plates c and packing e* (through the holes provided therein)
and then riveted-whereby said two plates c and packing are all firmly secured
together to thus form the division pieces or partitions of special construction
according to my present invention.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Constructing the division pieces or partitions for dividing into a number
of compartments the ink ducts or fountains of printing machinery for multi-
colour or other printing-by forming same of two plates or cheeks of a suitable
rigid material such as sheet metal non-corrodible by ink and shaped to correspond
with the bottom of the ink duct and the duct roller respectively with a sheet of
india-rubber or equivalent inserted and secured therein between and projecting
beyond the aforesaid shaped edges to serve as a packing in combination and
acting in conjunction with means to independently adjust and fix each said
partition in any desired position in the ink trough substantially as and for the
purposes herein before described.
2. Constructing the division pieces or partitions for dividing into a number
of compartments the ink ducts or fountains of printing machinery for multi-
color or other printing by forming same of two plates or cheeks c of sheet metal
non-corrodible by ink with the edge curved to the radius of the duct roller and
the edge shaped to correspond with the bottom of the ink duct, a sheet of india
rubber inserted and secured in between said metal cheeks c and projecting beyond
same along the edges cl and c² thereof so as to form a packing in combination
and acting in conjunction with means to independently adjust and fix each said
partition in any desired position in the ink trough substantially as and for the
purposes herein before described.
3. Constructing the division pieces or partitions-for dividing into a number
of compartments the ink ducts or fountains of printing machinery for multi-
colour or other printing by forming same of two plates or cheeks c of sheet
metal non-corrodible by ink with the edge c curved to the radius of the duct
roller and the edge c² shaped to correspond with the bottom of the ink duct, a
sheet of india rubber inserted and secured in between said metal cheeks c and
projecting beyond same along the edges and c² thereof so as to form a pack-
ing, in combination and acting in conjunction with a slotted plate such as d
mounted over the ink trough, slide blocks such as f adapted to slide in said slot
and be guided therein by means of horizontal grooves f¹ f2 (in each said block f)
fitting over and corresponding to the edges d' of said slotted plate d, a vertical
hole through each said block tapped to receive a screw therein a screw adapted
to screw through said block a saddle or forked device h swivelled to the lower end
of said screw and adapted to embrace and hold one of the said partitions, and
means at the upper end of said screw whereby to revolve same substantially in
the manner and for the purposes herein before set forth.
4. The improved construction of division pieces or partitions and means of
adjusting and fixing same for dividing into a number of compartments the ink
ducts or fountains of printing machinery for multi-colour or other printing all
combined and arranged to act substantially in the manner and for the purposes
hereinbefore described and illustrated in the drawings hereunto annexed.
