Ink Ducts.
WALTER ALLEN, 11, Clerkenwell Close, and CHARLES WOLFE, 43, Wiskin Street,
Clerkenwell, both of London, Engineers, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to provide means whereby the stop-pieces which are
used to regulate the distribution of Ink or other fluid in Binder's, Printer's and
similar ducts can be securely locked at the required distances, thus obviating the
lateral creeping motion which they are at present subjected to, and more especially so
when a variety of colored inks are employed.
And for an improved method of revolving the Duct roller.
For this purpose I preferably adjust a grooved plate or travelling rod parallel and
in proximity with the duct and duct roller, the said groove being shaped in a
longitudinal direction and somewhat of dovetail form-The said grooved plate is
furnished with a number of travellers or sliding catches formed in such a manner
that their bases correspond with the shape of the groove, thus permitting a lateral
motion only when required, these travellers slightly project over the ink duct and
are provided with set screws which are employed to lock the stop pieces for regulating
the supply of ink or other fluid at their proper distances and at the same time
securing the travellers in or against the grooved plate or travelling rod by a levering
motion.
Instead of employing set screws springs can be provided, and the travellers may be
shaped in such a manner that their bases correspond with the outer surfaces of a
travelling rod in place of being of dovetail form, or the springs or catches may be

surface.
An arm placed at a suitable angle and fixed to the table of the press is provided to
raise a pawl lever to lessen the amount of resistance for revolving the duct roller.
The pawl lever is an attachment to the Duct roller and is furnished with a pawl
which engages with a ratchet wheel combined with the said roller, upon the table of
the press receiving an inward thrust the aforesaid arm fixed thereto raises or levers
by a gradual motion the pawl lever which in parts through the pawl and ratchet a
reciprocating motion to the duct roller.

Improvements in and Connected with Binders' and Printers'
Ink Ducts.
We, WALTER ALLEN and CHARLES WOLFE, both of Clerkenwell, in the county of
Middlesex, Engineers, do hereby declare the nature of the said 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 improved means of ensuring the desired positions of the
movable stops or division pieces by which the separation of the colors or the dis-
tribution of the inks or other liquids is effected in binder's, printer's and similar
ducts; but is especially applicable to blocking prosses of the nature illustrated in the
drawings accompanying the Specification of Lotters Patent granted to us on the
27th day of October, 1884, No. 14181, and in which are combined a vertically
reciprocating press block by which the desired impressions are given to the book or
article under treatment, and an under horizontally reciprocating table and inking
apparatus, the former of which serves to support the book or article while being
pressed as aforesaid, and the latter of which is adapted to take ink or color from an
intermittently rotating duct roller operated by the forward reciprocating movement of
the said table and from a stationary inking or distributing table and to distribute it as
required on the under surface of the block ready for the next impression; the special
objects of the Invention being to prevent the shifting or lateral creeping motion to
which such stops are subject as at present applied in such apparatus; and to cause
the intermittent rotating movement of the duct roller to be more easily and advan-
tageously effected than as at present.
The accompanying drawings illustrate the inking apparatus of a blocking press
adapted in accordance with part of the Invention the subject of our said former
Letters Patent, and also illustrate the application of the present improvements
thereto.
Fig. 1. represents a side elevation of such apparatus, representing the same as
adapted with the present improvements. Fig. 2. represents a plan view thereof.
Figs. 3. and 4, are drawn to a larger scale, and respectively represent a sectional
elevation and partial plan view of the ink or color duct and duct roller, and the
improved means of securing the said division pieces.
5. represents the duct for containing the ink, color or liquid required to be used,
and, 6. represents the duct roller, by the intermittent rotation of which in the
direction of the arrow, 7, the said ink, color or liquid is supplied to a travelling
roller, 8, supported by the travelling frame, 9, when the latter is slid thereover in the
direction of the arrow, 10, and by which roller when the movement of the frame, 9, is
reversed, the said ink, color or liquid is transferred to the table, 11, from which it is
transferred in the usual manner by the rollers, 12, to the printing block, 13, which
is indicated in dotted lines.
14, represents the removable stop pieces which are shaped to conform to the roller
and to the duct, and by which the duct, in such and other analogous inking apparatus,
is divided off as required, either in such a manner as to use only any required
longitudinal extent thereof, or for dividing it off into different sections or portions for
the reception of various inks, colors or liquids, such as when requiring to print in two
or more colors at one operation of the press, and each of which sections or portions
may be of any required length, and which is effected in a usual manner by placing
the stop pieces, 14, in such positions as may be desired.

page_text: The especial object of part of our present improvements is, as aforesaid, to ensure
the desired positions of such stops or division pieces in such a manner as to prevent
the same from shifting in position during the operation of the press; and this we
effect in accordance with such part of our said improvements, by constructing the
frame, 15, of the duct with a recess or guiding slot, 16, running longitudinally
thereof, and parallel with and in proximity to the duct, 5, and preferably made of an
undercut or dovetail shape in cross section, and by adapting to such recess or slot
removable hold-fasts or detaining devices, 17, one to each stop-piece, 14, and each
consisting essentially of a part corresponding in formation with that of the slot, 16,
and of a part, (preferably overhanging the duct) to which a thumb-screw, 19, is
applied in such a manner that when turned in the proper direction it is caused to
press the stop piece, 14, above which it is adjusted securely down into the duct and
against the duct-roller, such turning movement of the screw being also effective in
jamming the holdfast firmly in the said dovetail slot, 16. The position of the
stops, 14, is thus effectually ensured for so long as may be desired, and when it is
required to remove any stop, or to shift its position, this can at any time be effected,
it being first relieved from the pressure of its detaining screw by unscrewing the
latter to a sufficient extent.
As an equivalent arrangement to that hereinbefore described, the slot, 16, may be
formed in a separate plate to be bolted or screwed to the frame, 15.
The duct roller, 6, is intermittently rotated, in accordance with the present improve-
ments, by means of a pawl, 20, which engages with a ratchet wheel, 18, fast on the
duct roller shaft, 21, and is centred at, 22, to a lever-arm, 23, which is mounted
loosely on the duct roller shaft, and at its free end is adapted with a freely turning
roller, 24.
The position of the lever arm, 23, when out of action, is indicated by the dotted
lines in Fig. 1, in which it rests upon the stop piece, 25, bolted to the frame, and the
method of its actuation in accordance with the present improvements is indicated in
the same Fig. in full lines.
In the operation of the apparatus during the forward movement of the said
travelling frame, 9, the lever arm, 23, is very gradually raised by means of an
incline, 26, which is bolted or otherwise suitably secured to such frame; and which
operates upon the roller, 24, of the lever arm, and by such means operating the
pawl, 20, the duct roller, 6, is very gradually rotated, and with much greater ease
than as heretofore actuated.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The hereinbefore described improved means of ensuring the desired positions of
the movable stops or division pieces by which the separation of the colors or the
distribution of the inks or other liquids is effected in binder's, printer's and similar
ducts.
2. The application of such improved means referred to in Claim 1. and of the
herein before described improved means of intermittently rotating the duct roller,
separately, and in combination, to inking apparatus constructed and adapted sub-
stantially as hereinbefore referred to and as represented in the accompanying
drawings.
