COMPLETE SPECIFICATION
Improvements in Multi-colour Printing, and in Apparatus to be
Employed therein.
I THEODORE JONES TURLEY of 315 E clid Avenue, Nashville, Davidson
County, Tennessee in the United States of America, Banker do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertamed in and by the following statoment
My invention relates to improvements in multi-color printing devices (that is
devices for printing in two or more colours including black as a colour when
equed) and it is specially applicable to newspaper and magazine or similar work
where it is desuable to print advertisements, announcements, headings, ornamenta-
tions, and the like, in colors contrasting with the body of the paper or the like on
which the printing is effected.
My main objects are to provide attachments that can be readily applied to
existing pinting presses, without requiring any alteration in the construction of
Buch presses, and to make various forms of such attachments rendering my
invention suitable for the various classes of work in which multi-color printing is
used, so that the various colors may be printed at one impression, thus avoiding in
ordinary cases the necessity of passing the paper through the press more than once.
and in no case more than twice, the latter being required in one form of my
invention, though the punting is practically effected even in this case with
substantially the same expenditure of time and labor as in punting by one
impression.
My further objects are to simplify to a great extent the mechanism for operating
such devices; to provide means for readily placing the device within the main form
at any point desued, without confining it to a particular space in the columu, to
provide means whereby the width of the colored matter to be printed may be easily
varied without it being necessary to provide separate complete forms for various
widths, such as one, two or three columns; and to reduce the space lost in luking
the supplemental form aud insure the thorough king of the whole of the said
form, and generally to improve the construction and operation of this class of
devices
I attain these objects by the mechanism shewn in the accompanying drawings,
and hereinafter describedl

Figures 34 to 40 illustrate the application of my color inking apparatus to bed
and cylinder presses, and to perfecting presses for tinting a background
Referring to Figures 1 to 6, a supplemental form E, is retained within a frame X,
normally below type-high so that the inking apparatus is to be so adjusted that its
inking roller will dip below type-high for king the supplemental form.
The letter A. indicates a poition of the frame of a piess on which are supported
the impression cylinder C, the feed table B, and the bed D, carrying the main
form E, in which is locked at the point desired my color printing device o.
supplemental form E. This device consists of an open rectangular fame X, having
inclined lugs e, projecting upwardly from the bottom and ribs a, with flat upper inces
extending longitudinally of the frame. The supplemental form-holder E upon which
electrotype or plate is seemed, has coresponding inclined lugs e, and ribs with flat
lower faces, depending therefrom, adapted to engage the inclined lugs e', of the
frame, so that as the form-holder is moved transversely of the frame, it will also bo
cnused to move vertically upward until the flat faces of its lugs e, rest upon the ribs
or projections a, of the fiame, affording a firm base for the form-holder when an
impression is taken.
A bell crank lever is pivoted on the frame, its two arms W and W', bemg in
different horizontal planes, the former engaging a slot win a spring actuated dog V,
while the latter is connected to the form-holder by a pin to, projecting upwardly
into a socket in the bottom of the form-holder. In the sides of the form-holdet arc
guide ways e, into which the pins ell, passing through the sides of the frame X,
enter for the purpose of limiting the upward movement of the form-holder and
preventing its displacement from any cause.
The side bar U, is detachably secured to the frame by a forked lug u, which
snugly holds the bar from any lateral movement. By making the side bar separable
from the frame the latter can be readily locked within the main form E at any
portion of the column and the side bar easily adjusted, the space between it and
the frame being filled in with ordinary printers' side stick. It is to be understood,
of course, that the supplemental form-holder is used at the side ouly of the nam
form.
The side bar U, is provided with a slot, in one end of which is journalled a
roller, upon which rests an inclined projection or cam e', on the front end of the
dog V. This dog has on its rear end a slot v', through which a pivot pin 9, passes,
forming a fulcrum upon which the dog moves forward and upward, the forward
movement being limited by the length of the slot. In its lower position, the dog
rests upon webs g, extending across the forward portion of the slot and into recesses
in the lower face of the dog. A spring, in the slot », of the dog, with one end
engaging the pin 7, and the other in contact with the front end of the slot in the

page_text: dog, tends to press the dog forward against the roller x, upon which the cnm x',
rides, thus norinally holding the free end of the dog up aud keeping the arm W, of
the bell cıank lever in its extreme forward position, thereby retaining the form-
boldor normally below type-high.
Upon the outer edge of the side bar U is an elevated track or rail ¹, for
operating the roller T, on the end of an arm t, Figure 1, pivoted to the frame O,
of the inking apparatus, which arm carries at its opposite end the form roller T¹,
normally in contact with the main ink rollei Q, on the shaft R, above which are
the two distributive rolleis n. The frame O, of this inking apparatus is provided
with two clamping jaws N by means of which it is secured upon a cross bar K.
This bat is held in place between clamping jawa, on collar brackets I, preferably
adjustably mounted upon standards II, on brackets G, adjustably secured to the
main frame of the press. In Figure 1, the brackets G, are shown with single
clamping jaws, but it is obvious that there may be two or more such jaws. if it is
desired at any time to provide more than one inking apparatus, located at different
distances from the impression cylinder.
In the preferable construction the standards H nie formed in one with the
brackets G, and are preferably circular in cross section, to receive the collais I,
ou which are formed the clamping Jaws 1, which support the cross bar K, the sand
collars being capable of being raised and lowered on the standards and fixed nt
any height thereon by set screws.
Jounalled in ears, on each collar I, 16 a pinion L, gearing with rack teeth h,
formed longitudinally on the standards 11, the shaft of the pinion being provided
with a hand wheel M, by which the pinion can be rotated. By this construction,
it will be seen that when it is desired to raise or lower the collar, the binding
screw which fixes the colla is eased, and the operator turns the hand wheel M,
in the desned duection, causing the pinion L, to rotate in gear with the rack h,
thus moving the said collar up or down.
As the form E passes under the inking apparatus, the cam tinck ', engages
the wheel T, thereby causing the form roller T at the opposite end of the aim t,
on which the two are mounted to be depressed below type-high so as to ink the
form E with ink, fed to the roller Q, from the reservoir P, by the doctor roller m³.
Passing under the impression cylinder C which is now above type-high, there is
no eflect upon the supplemental painting device. Upon the reversal of the bed,
the impression cylinder C being lowered to type high, ongages the dog V,
depressing it and causing the bell crank lever W W to move the supplemental
form to type-high for an impression.
In order to provide for the printing of colors in various widths without having
to provide separate complete devices for the different widths, I form the sides of
the frame X, and the ribs e', detachable as shown in Figure 10, the side frames "
and y, being secured together by dovetail joints, at the ends, aud provided with
mortises into which corresponding tenons y, formed on the ends of the bs a, me
adapted to fit The bottom of the frame, in this construction, forms a "guid"
composed of the several libs a. When it is desired therefore to alter the width
of the color printing, the frame can be readily dismantled, the side pieces of the
proper length selected and the form readily assembled with the parts in the same
relation as above described.
Between the edge of the frame and the point where the form roller first strikes
the plate or type upon the form-holder, there is considerable lost space, and to
insure a proper inking of the whole of the supplemental form, and at the same
time reduce this space to a minunum, I employ the construction shown in Figure 11
which is an enlarged view of a portion of the making apparatus.
Instead of employing a single roller upon the aim t which is moved by the track
or al u, to uk the supplemental form, au additional roller t' of larger diameter
than the roller T¹ is jou nalled in an upward extension of the said arm, and both
receiving ink from a roller " 1otating in contact therewith. By this arrangement,
the form 1ollers can be caused to dip more closely to the edge of the frame X and

page_text: enter the form close to the edge of the same than where a single oller of larger
diameter is used. Motion 18 transmitted to the inking olleis, from the bed of
the press by a friction wheel S, which should be in contact with the chase, but
I do not wish to be restricted to this means of transmitting such motion as in
presses where the impression cylinder is provided with a cucular ack, other
suitable means may be employed for this purpoчe
The
In Figures 7 and 8 I have shown a construction similar to that illustrated in the
preceding figues with a supplemental form E, aanged to print a colored border
or other matter around a contrasting centre. The means for accomplishing this
result consists of the centrally apertured supplemental form-holder E, seemed by
posts, passing through an aperture 2', in a voitically and horizontally movable
plate E to a frame Z, arranged to rise and fall between the inclined lugs el on
the bottom of the frame X. The aperture in the plate E, is of sufficient leugth
in the direction of the horizontal motion of the said plate to allow of the said
motion without coming in contact with the form-holder E. Springs ', inter posed
between the frame Z, and the plate E, near the edges of the aperture,
normally tend to keep the form-holder E, sented upon the said plate below_type-
high. Two levels y and fulciumed at the bottom of the frame X, and
connected by a pin upon one of the said aims and engaging a slot in the other
aim, extend upwardly and support by a sliding contact, the frame Z
lever y, is prolonged through sluts or openings in the side bar U, and dog V, with
an arm, curved upwardly and adapted to be pressed downward by any suitable
means (such as a shoe Figure 9, secured by a bolt, to a downwardly
projecting standard g, supported by the cross bar K.) so as to cause the upper
ends of the levers yy to raise the frame Z, and the attached form-holder E,
above type-high, as it passes under the supplemental mking apparatus When
the army, is released from the shoe z", the springs 2, will push the fame Z,
downward until the form-holder E, is seated upon the plate E. The form-
holder E', is firmly fastened by any suitable means to the lugs in the frame X,
and projects up through the aperture E in the form-holder E, and always carries
its form at type-high so that the latter may be inked by the man ink rollers. By
this arrangement it will be seen that two colors may be printed by the same device,
one either as a plain border, around the cential electiotype or plate, in contrasting
color, or either or both in letters, figures etc, of different colors.
As a modification of the supplemental form and its connections, I sometimes
use the construction shown in Figures 12 to 14, particularly where it is desired
to print more than one color in the same column, necessitating the use of two or
more torms close together.
In this coustiuction, the supplemental form is aanged to move longitudinally
of the bed of the press instead of transversely as in the construction shown in
Figures 1 to 11. Referring now particularly to Figures 12 to 14 the frame X of
the supplemental form E, is adapted to be locked within the main form, and is
provided with transverse tuclined ribs el against which corresponding bae,
depending from the supplemental form E, are adapted to act, so as to move the
form bonizontally and vertically within the frame X The movement of the form E,
will thus be in the duection of the length of the press and not transversely as in
the former instance In connection with the frame X, is a side bar U, preferably
separable from the frame, so that the frame and form may be placed in any column
of the main form, the side bar being at the side of the bed of the press, for the
purpose hereinafter described. Upon the outer edge of this side bai is an elevated
ial or track ', of a length equal to the length of the matter to be painted in
color by the supplemental form. When properly placed, the rail is adapted
to engage the roller T, on the end of the arm cariying the form roller T' so as to
depress the said form roller into contact with the electroty pe, or plate, on the
supplemental form E.
Extending transversely of the fiame X, is a rock shaft, fiom which an aim
projects upwardly, and is connected by a sliding connection to the end of the

page_text: form E. This 1ock shaft may be of various lengths according to the distance of
the supplemental frame from the side of the bed of the press on which the side
lai U, is a ranged. A spring' connects the rock shaft with the frame X, and
tends to keep the supplemental form E, normally below type high. Instead of
placing the sping on the rock shaft, I may employ a spring or springs between
the back of the frame and the form, in which case the arm may be provided with a
ollei in sliding contact with the form.
Upon one end of the rock shaft is an arm f which is preferably provided on
its upper end with a friction ruller and projects normally slightly above type-high,
Fulcrumed to the side bai U, at between lugs thereon is a lever V, of a length
equal to or slightly greater than the length of the matter to be printed. This
lever extends over and rests upon the end of the arm which arm keeps the said
lever normally elevated above the side bar as shewn in Figure 14, where its position
is slightly exaggerated for the purpose of better illustration. It will thus be scen
that when the impression cylinder is lowered to typo high as the form passes theic-
under the lever V₁ will be pressed down by the impression cylinder thereby turning
the arm, and the lock shaft f, to which it is attached, and elevating the
supplemental form on the inclined ribs e' to type high for an impression.
I prefer to use, with this device, an inking apparatus, similar to that already
desciibed
The impression cylinder C, in the operation of the device is normally slightly
above type-high so that as the bed and the supplemental form locked therein is
moved back and forth no effect is had upon the elevating mechanism until the
impression cylinder is lowered to type high. In the movement of the bed of the
press to the light the track a elevates the roller T, depressing the form toller T,
and mks the type or electio plate upon the supplemental form E, and as the form
passes underneath the impression cylinder which is above type high, love VI just
Clears the same Upon the reversal of the bed of the press, the impression
cylinder being lowered to type high, engages the lever V, depressing the same and
elevating the form E, thereby causing an impression to be taken
When the form passes from under the impression cylinder, the spring causes
the rock shaft to lower the form to its normal position below type-high
While my present invention is preferably used with other supplemental forms, it
is of course equally adapted for separate use
For large piesses and for the greatest range of work, I prefer to use the con-
structions whereby I cau dispense with the use of supplemental forms, though I
may still use the same character of inking apparatus as her erubefore described,
with slight modifications as may be found desuable. In these constructions I still
maintain the feature of "attachment to the ordinary" press, and it is manifest that
It is very desi able to print upon ordinary type, without using the supplemental form
Refemng to Figures 15-25, 1 should state at the outset that while I have
shown in Figures 15 and 16, the form as extending nearly across the bed of the
press it is to be understood that the matter to be painted may occupy greater o
less space in width and length, the particular width and length simply being shown
for the purpose of clear illustration.
To adapt the color uhers for use in connection with my main ink rollers, a
slightly modified construction of the device for causing the color ink roller to ink
its appropriate matter is necessary, as will appear in the description to follow.
In Figure 15, the matter is hyed in an ordinary chase with the lines aanged in a
direction laterally of the bed D, of the press to which it is secured in the usual
manner. The press is of course, supplied with the ordinary ink fountain and tablo
arianged and operating in the usual way. The form is composed of ordinary
type from which different colors, red, black, blue and yellow nie to be printed as
indicated by the names of said colors. The form 18 locked in the chase by quoins
as customary.
The color inking devices are arranged in proper position with reference to tho

page_text: impression cylinder side by side laterally of the press, Figure 15 or longitudinally
in advance of the other as in Figure 16, according as the form is placed laterally
un longitudinally of the press
The side frames 0, of these king devices are clamped to a cross-bai or cross
bars K, which may be supported by brackets ( as shewn in Figure 1, or as shown
In Figures 15, 16 by biachets attached to the framing A of the press.
Jom nalled in these frames are main rollers Q and distributing and feed rollers n.
Mounted above the rollor Q, is a suitable reservon Pas shown in Figure 22, from
which ink is fed to the roller Q, by the ductor rollers m and m Aims are
fulcrumed in the lower part of the flames O, and each of the said aims carries
at one end a form roller T and at the opposito end a small wheel T see Figme 19,
the latter of which is adapted to be elevated by coming in contact with metal
strips locked within the form and placo below type high, thus depressing the
form roller and causing the said rollei to mk the form. These strips
are made
of standard lengths and can be readily set up with the type with the usual furniture.
The form ollei T is normally held above type high by any suitable means, such
for instance as a sping between the aim t, and the frame O.
To give motion to the color ink rollers I preferably mount them on a shaft R,
provided at one or both ends with a fuction wheel S, uning in contact with metul
strips, set in the main frame at any suitable point or secured to the bed in any
suitable manneı. These strips are shown at a slight distance from the edge of
the form, but they may be placed alongside of the form, or the wheels may
be operated by the edge of the chase if desired.
When the colors extend lengthwise of the form, and the latter is placed laterally
of the press bed as in Figure 15, the strips s' for operating the color inkers are of
uniform height and the same length as the matter to bo printed in a given color,
but where the form is placed longitudinally of the press bed, these strips must be
of different construction as shown in Figure 17, where it will be secu that one of
the stups & is provided with a cam projection or elevated rail, corresponding in
length to the length of matter to be punted in colo -in the instance shown, to the
length of the "yellow." The roller T being normally above type high will be
thus depressed ouly when the wheel T is raised by the elevated rail or cam
projection, on this strip, as it passes under the olleis. The other strip shown
has two projections, but any number may of course be employed in accordance
with the number of colors to be printed.
Up to this point the construction and the operation of the inkeis somewhat
resemble that bereinbefore described, the main point of difference lying in the
omission of the supplemental form and holder, and in the introduction of the metal
strips in the body of the form for operating the wheels T'. In the present case
however the ordinary main mik rollers are removed (Figure 15,) and in their
bearings are mounted biachets having projecting bosses or pins of the same
diameter as the shafts of the rollers removed so that they can readily be seated m
the beatings of the said rollers. These bosses may be confined to the bearings by
the same cap and screws or bolts used with the old mk rollers
Supported by the upper ends of the brackets M' is a transversely extending
bar K passing through rectangular or polygonal holes in the frames, in which the
said bat can be moved laterally of the press but not otherwise.
Jounalled in suitable frames, clamped to this bar by set screws, is a shaft r,
upon which are mounted the sectional main ink rollers of standard widths
corresponding to the width of the matter to be printed in black, the said rollers
aligning with such matter On the shaft are secured collats to hold the rollers
against lateral displacement, and between the separato rollers in proper order,
are placed spacing collars of less diameter than the tollers
These spacing
collais are of various standard lengths, such as 1 2. 3. 4. 5. 6. and so ou "ems
and aligu when properly adjusted with the matter to be printed in colors. If the
blue matter is "ems" wide, the spacing collar aligning therewith will be n“ eins
"

page_text: and so forth By making these collars of standard lengths, the pressinan
enabled to quickly and accurately assemble the black ink rolleis upon the shaft
which is preferably done as follows-The form is placed upon the imposing
stone, at each end of which is secured a suitable supporting plate and the shaft r is
placed in the beating of these plates, and a collar is first secured in place thereon
at a point opposite the outer line of the hist column of matter. The sectional ink
1ollers are then shipped on the shaft with the spacing collars ' in proper order
and finally all is clamped in position by the other end collar .
The frames or brackets M' are unclumped from the bar K', and the ink roller
shaft quickly set in the bearings of the said brackets, which are again clamped in
position upon the bar K, so that the black ink rollers will align with then
appropriate matter, and the spaces between them formed by the collars fall
opposite the color type.
Against the sides of the sectional rollers, I preferably place thin metallic
washers for the purpose of preventing the said rollers from spreading while in
contact with the form.
By this construction of inain ink rolleis it will be seen that they can be quickly
and accurately adjusted in proper position upon the shaft, and then readily attached
to the press. With the form placed laterally on the bed, the main ink rollers
remam always at a fixed distance above the form, but if for any reason it is desired
to place the form longitudinally of the press, as in Figure 16, the main ink rollers
must be raised to clear the type for other colors To accomplish this 1 employ
the construction shewn in Figures 16 to 20 where the main uk rollers Ti nie
mounted in slotted bearings in the frames O' instead of circulai bearings so as to
provide for a slight vertical movement of the shafts R' on which the said rollei>
are mounted. Two sets of rollers are preferably employed but it is manifest that
one set might be used in either of the constructions shown. Suitable distributing
ollers set at an angle to the main tollers are mounted loosely on shafts carried
m bearings on the frames O' above the bearings of the rollers 'T' so that the said
distributing rollers may vibrate across the face of the ink rollers as the latter are
tuned by the ink table, thus spreading the ink evenly on the black ink
rollers.
Pivotted to the frames O', are levers having one end normally held upward by
springs connected to the flames Oue aim of each of the said levers is preferably
provided with a recess in which the end of the shaft R' may rest, while the other
eud carries a wheel T adapted to be engaged by the elevations or cam tracks on
the metal strips locked in the form at each side thereof and outside of the
strips s, herein before described
By
Depressions alternate with the elevations on the said strips such depressions
corresponding in length to the length of the matter to be printed in colors.
this arrangement it will be seen that as the form moves under tho black ink rollors,
the wheels T will be alternately depressed and raised, running in the depressions
while the color type is passing under the black ink roller which is thus raised by
the spings above type-high to clear the color type Riding on these elevations or
rails, the wheel is raised thereby depressing the black ink roller into contact with
the black type matter.
With the inkers and strips airauged as described and shown in Figure 16 it
Bill be plain that the color ink will be deposited upon the appropriate section of
the form as the wheels T, are raised by the rails or olovations as the form passes
under the color inkers while the color ink rolleis T will be held clear of the black
type as the wheels 'T' pass from their rails In a similar manner the depressions
on one of the strips s permit the wheels T' to lower thereby raising the black ink
roller above the type, while the elevations raise the said wheels at the proper time,
to cause the black ink rollers to ink the matter to be printed in black.
As a modification of the foregoing construction I may employ the construction
illustrated in Figures 21 to 23 inclusivo, in which the metal strips for depressing
the color ink rollers are arranged outside the form instead of being locked within

page_text: the said form. In these figures the cross bar K supports the frames O* in which
are jou nalled the main ink cylinder or roller Q, and the vibrating distributing
rollers. The reservoir P, is seemed to the frames O' in a horizontal position,
and carries in its feeding end the ductor roller, m on the axis of which is a ratchet
wheel, m, engaged by a pawl, m³ carried at one end of a rod, I, to which a recipro-
eating motion is given by any suitable means, such for instance as a pitman,
nctuated by an eccentric, mounted upon the rotating shaft of the main ink
roller, or by any other suitable cam rotating with the said ink rolleı.
Extending transversely of the frames is a rock shaft from which project two
aums, in the outer ends of which 18 mounted a suitable shaft upon which the
ductor roller m² 15 journalled.
To one of these arms is connected a rod 1 having a projecting stud upon its
lower end (see Figure 22A) engaging a cam on the end of the main roller Q and
so timed that the said rod may be raised as the pawl and ratchet nie operated to
turn the ducto roller, m, thus taking ink from the esei von and feeding it
intermittently to the main roller, Q Near the edge of the bed of the press is a
supplemental fiame or hanger O Figure 23 which is clamped to the cross bar, K,
and passing through bearings in this hanger and one of the finmes (* is a shaft R
upon the outer end of which shaft is mounted a friction wheel S¹ in operative
contact with a metal bai S³ (preferably corrugated) extending the whole length of
the bed of the press
Motion is transmitted from the shaft R to the shaft R of
the ink rollei Q, by a gear g², meshing with a gear o³ on the shaft R. The bar S'
18 preferably provided with an upwardly projecting tongue S³, upon which 18
adapted to be seated grooved metal strips S corresponding to the metal strips
Figure 17 and at each end of the said strips is placed an inclined block S' winch
is held in position by a fiction screw clamp S passing through the side of the
block and engaging by functional contact, the side of tongue 8. These strips
are to be of a length coresponding to the length of the matter to be printed in
colors. A vibrating shaft R³ passes through a bearing in the opposite side of the
fame O and through bearings in the lower part of the frames On this shaft
18 an arm p which is adapted to be raised by an upwardly projecting extension
on a vibrating aim t² which is pivotally supported upon the frame O³, the aim t
carries at its fice end a fiction wheel or 1oller T which is adapted to be engaged
by the inclined block S and thus caused to pass without jerk or jar upon and from
the strip St at a predetermined point in the movement of the bed of the press
upward extension pupon the arin is provided with a laterally projecting lug or
boss through which a set screw passes and bears upon the top edge of the frame by
which the vertical movement of the arm may be regulated. A stud on the
frame O³ works in a guide slot p³ in the aim or the guide may be on the frame
and the stud upon the hanger if desired
An
On the shaft R' between the frames O2 are laterally extending ating p* having
studs projecting therefrom, and engaging the upper edge of an offset in the
frames in which the form tolle T is mounted. These frames are slidably
connected with the frames O' by the vertical guide pins 2, working in sockets in
the lugs A on the said fiames O2 and are pivotally connected to the said fiames by
a link while they are connected together by the tie rod p
The shaft of the form tolle T is mounted in curved slotted bearings in the
frames and a set screw limits the movement of the shaft in its bearings, which
movement may be varied by proper adjustment of the said act sciew
A spring connects the form roller shaft with the frame 02, thus normally
holding the sliding fames in the extreme upward position, and consequently
Leeping the form ioller normally out of contact with the form on the bed of the
press.
As the wheel T' comes in contact with the strip S₁ it is raised, thereby raising
the aim whose extension p³ comes in contact with and moves the nim p on the
end of the shaft R* rocking the latter and causing the arms p to lower. The
movement of this arm downward depresses the frames and the form roller carried

page_text: thereby, until the latter is brought into contact with the form on the press, to inк
the same.
As soon as the wheel is released from the strip S the spring s³ draws
the roller out of contact with the form.
I have described two arms, p' for depressing the frames k', but it is obvious that
one may answer the purpose, though it is preferable to use two because of the equal
distribution of the strains secured thereby.
In soing cases it may not be convenient or possible to arrange all the color inkers
back of the impression cylinder or under the feed boaid as in the construction
herein before described, and in back delivery presses, it is obvious that these inkers
cannot all be applied under the feed board but must be at ranged in front of the
impression cylinder In Figures 24 and 25 I have shown such modification of my
invention as will readily meet this contingency. In these figures, the mkers back
of the impression cylinder are in all respects the same as that disclosed in
Figmes 21 to 23 one of these inkers is adapted to print the blue and a short
strip S for depressing the "blue" roller Ta will be used, while the other roller T"

canaly
"rollei T, the stupa S in each case corresponding in length to the
length of color to be printed.

The back ink rollers are in every respect similar to those employed in connection
with the construction shown in Figure 15 to apply the other colonis- this case
red orange and green-a shaft R' is Journalled in slotted bearings in the brackets
which brackets also cari y the shaft for the black ink rolleis Upon this shaft K
winch is capable of a limited vertical movement, are the sectional ink rollers of
standard "em" lengths and secured thereon with spacing collais if desired, in the
same manner as tho black ink rollers. On the outer ends of this shaft nie two
fiction wheels F which are of slightly greater diameter than the ink rollers. As
long as these wheels are on the ink table, the rollers r' will therefore be held above
type high while black ink is being applied to the rollers
Extending from the edge of the ink table (not shown) to the end of the bed of
the press are two strips of metal S' in line with the wheels F, in each of which
strips there is a depression SB which is to register with the colors, red, orange and
green in the form. While the wheels F are in contact with the elevated portions
of these strips the rollers are held above ty pe-high, but the moment these wheels
run into the depressions S the shaft R' is lowered and the rollers ink the form.
To supply ink to these several rollers, I use the frame O' with all its appar-
tenances except the rollers T, their necessary operating parts, and the supplemental
frame and appendages.
Instead of using friction wheels for turning the mam uk cylinders QI use a
gear S' on the shaft of the ink roller Q, meshing with the rack S10 which is placed
on the edge of the beds of all bed and cylinder presses
Some of the advantages of my mnvention are manifest since it is clear that the
simple means provided for readily attaching the black ink rollers to the press, and
the spacing collars and the rollers of standard lengths are both conducive to
economy of time and labour in making ready. and the introduction of the metallic
strips of standard lengths adds further to this result. And again the provision of
separated and independent color rollers in combination with separate distributing
rollers and mk supplies for each of such color rollers, overcomes a serious objection
found in prior constructions for printing in a plurality of colors at one impression
since by my construction I entirely obviate the mingling or blending of culors
heretofore existing in this type of machines
Although I have shown a particular form of brackets for supporting the black
ink rolls it is obvious that this form may be varied without departing from my
invention, and it is equally clear that, in cases where it is desired, these brackets
may be attached directly to the framing.
It is also to be understood that the frames M' for supporting the black ink
ollers may be duplex, as shewn in either of the constructions used, or single, that
se, they may have one or more sets of bearings for black ink rollers according as
B

page_text: it is desired to use oue or more of such rollers. The frame shewn in Figure 20
may be used with the construction shown in Figure 15 without alteration, and it is
intended to be so used, omitting the wheels T because the black ink rollers in that
construction are fixed with respect to the form.
Figure 26 illustrates a novel method of chromatic printing in which two or more
contrasting colours are printed in close register
In the drawing, C indicates in dotted lines, the position of the impression
cylinder, A represents the side frames of the press, D the bed, M' the frames for
supporting the sectional form rollers, which, as before stated, may be
operated by any of the ways known to the art, but preferably by the mechanism
herein before described.
In carrying out this part of my invention the plate or electrotype, carrying the
design, is locked within the main forin, in line with the several inking rollers, two
of these plates E and E', being locked together in line transversely of the press
one of these founs E, it will be observed, (in this case the upper one) is intended
to print the ground work or body color, or colors, while the lower one E 1S
intended to print the close register, skeleton or hair hues, or shade lines, which
will surround the several portions of the body work. As shown in the drawings
the words "Summer Time are to be printed in "red opposite to which is the
red ink roller, and the sketch, on picture, is to be printed in "black," opposite the
black ink roller, and the descriptive words "By Lola are to be printed in
opposite the orange ink roller, while the inscription, Published by

orange
"
"
"
"
Blue & Co is to be printed in "blue" and is opposite the blue ink roller; and
the hair lines, the marginal lines, and shade lines, are to be printed by the sectional
" green "ink rolle. It will now be seen. for example, if 2,000 sheets are to be
printed with any given design having a plurality of color, five for example,
1,000 sheets of paper of suitable lengths for containing two designs end to end, are
passed through the press, and two impressions are made or imprinted upon each sheet,
the upper one of which will cont un fou colors, as above descubed, and the lower
one a single color, green, in this instance, the latter of which constitutes the hair
line or shade line color. After the 1000 sheets have been run through the press
in this mauner, the whole is turned end for end, that is, through 180 degrees, and
are repassed through the press in exactly the same manner as before, a second set
of double impressions being amprinted upon each sheet as it passes through the
The close register work will accordingly be impunted upon that part of
the sheet or paper upon which the ground work was proviously punted, and the
ground work will be imprinted upon that part thereof whereon the close register
work was proviously unprinted
press
It will thus be seen that there will be 1,000 sheets finished, each containing two
complete designs thus making a total of 2,000 separate sheets, each having thercon
a complete design in five colors.
By using the sectional ink rollers at type high I am enabled to use the ordinary
ink table of the press for supplying ink to the said rollers, these rollers in such
case being placed on the opposite side of the impression cylinder from the other
ink rolleis. When the presses are not supplied with such ink tables, as is
sometimes the case the sectional rollers may be placed upon the same side of the
impression cylinder as the other ink rollers, if desired, and ink be supplied
thereto by supplemental inkers: and they may, or may not, in such case, be
noumally at type-high
One great advantage that arises from the practice of my new method is tho
fact that I am enabled to print contrasting colors, in close register, with practically
the same expenditure of work necessary to print the plurality of colors at one
impression, since a double impression is made at each run, and two complete
designs made with simply two runs of the press; and this result is effected by
attachments to the ordinary presses now in use, no change whatever being
required in the construction of the said presses in order that my invention may be
applied thereto

page_text: While I bave shown and described two forms for printing two impressions at a
run, it is obvious that an even multiple of these forms may be employed, the
arrangement of the color inking rollers being the same, for each set of two, as
that shown in the drawings. This number is limited in fact only by the size of
the forms used with respect to the width of the bed of the press upon which they
ale secured.
It is further plain that my improved method can be carried out on other forms
of presses besides that shown, for example, it may be effected upon a bed and
platen press, such as are commonly known in the art, where the printing is done
upon a web and the web moved, instead of moving the bed, as in the ordinary bed
and cylinder press, the essential principle of the method being to arrange the
forme, on whichever style of press used, transversely to the line of movement of
the inking devices so that what I have termed the groundwork may be printed
complete from one form, and the close register work, from the other form
while prefer to ink the cluse register in one color only, as shown, it is manifest
that both forms may be inked by sectional rollers in two or more colors, where it
is desired to do so
And
In some cases I provide an auxiliary ink table capable of being readily attached to
the bed of the press, in combination with form rollers to be inked thereby, normally
held at or slightly below typo-high, and sectional ink rollers at type-high adapted
to receive uk from the ordinary ink table, or other ink distributing apparatus, of
the press, with forms arranged side by side transversely or longitudinally of the
bed of the press.
Refening now particularly to Figures 27 to 30, the impression cylinder C, is
aised and lowered in the usual way. Sectional ink rollers are mounted in
suitable brackets G³, attached to the frame of the press which rollers receive their
ink from the ink table D', the upper surface of which is type-high, the type line
being at, or the said olleis may receive their ink from cylinder distributors
when such are attached to the press.
Upon the bed D, of the press are locked two formis E and E, each of which, in
the present instance, 18 one-half the width of the bed, and they are secmed
within the chase with the usual furniture
At the back of the impression cylinder is a transversely extending bar, or rod K,
supported in brackets G, attached to the framing A, of the press upon which rod
ate suspended two supplemental finmes, or hangers 0', forming extensions of the
ides of the ink box 01 esei von P. Mounted in slotted bearings g, in
brackets G', on the framing of the press, near the impression cylinder are form
ollers, normally pressed downward by suntable springs bearing upon then shafts
so as to keep the lower surface of the said rollers slightly below type-high.
Where the diameter of the form rolleis, is increased, the benings q', need not
extend as low as shown, suce the object is simply to have the form rollers slightly
below type-high in order that they may bear with sufficient pressure upon the ink
table and the form. Whenever this pressure is found sufficient with the said
rollers at type-high, they may be so arranged.
In the frames or hangers O, is a suitable number of slotted bearings g', in
which are journalled the ink distributang rollers n³, the lower ends of said bearings
being extended to such a point, in the present instance, as to keep the paid ink
distributing rollers preferably slightly above type-ligh, suntable springs resting
against the upper surface of the shatts of the distributing rollers act to press the
same against the lower ends of their bearings.
My auxiliary ink table D' see Figures 27 and 30 is provided with downwardly
and outwardly projecting lugs and borizontal lugs d, though which pass
respectively set screws and, to secure the said table to the bed of the press.
The horizontal lugs d', are adapted to project over the end of the bed of the press,
the outer ends being turned downward so as to pass between the wooden strip d'
usually at the end of the bed of the press, and the chase. The auxiliary table D'
may be adjusted horizontally and vertically, as desired, and fixed in position by the

page_text: screwɛ dª dº, the upper surface of the said table always being held slightly above
type-high. The bearings for the form and distributing rollers may be made
adjustable in any convenient manner.
In order to feed ink from the reservoir, or fountain P, to the auxiliary table D',
I mount upon the shaft of the ductor 1oller m, a lever g', Figures 27 and 27,
with a weight at its upper end, adjustable or not, as desired, the lower end of
which lever projects slightly below the bed of the press outside of the auxiliary
mk table. Fulcrumed upon the lever is a pawl g, engaging a ratchet wheel g",
secured to the shaft of the ductor roller m; and also attached to this lever is a
tappet o, the upper surface of which is arranged to come in contact with one end
of the shaft of the doctor roller m', mounted in slotted bearings in the frame, O'.
A similar lever glo, without the weight and pawl, extends downwardly from the
other side of the ink fountain, and caries a sunila tappet for engaging the other
end of the shaft of the doctor roller, the two levers being connected by a suitable
tie-iod so as to swing together. The doctor 1oller m', is normally out of contact with
the ductor roller m, but as the bed travels in the direction of the arrow Figure 27 the
end of the bed comes in contact with the lower end of the lever g', glo, causing the
same to swing about the axis of the shaft as a fulcium, thereby rotating the ductor
roller through the medium of the pawl g' and 1atchet g8, and at the same time causing
the tappets o, to use the doctor roller m', into contact with the ductor roller m
from which it receives ink from the fountain When the bed travels back and the
levers 97, 9, are released, the doctor roller drops upon the auxiliary ink table, to
which it translers the ink received from the fountain, the vibrating rollers n²,
spreading the same thereon in the usual manner.
10
Instead of suspending the inking apparatus thus described from the framing of
the press, it may, if desired, be suspended from soparate brackets mounted upon
the horizontal framing of the press. in which case, the hangers for carrying the
vibrating and distributing rollers may be integral, or they may be separate aud
supported by separate brackets.
In this construction, it will be observed, the distributing tollers never come in
contact with the form because they ate journalled in bearings outside of the
travel of the bed and therefore only touch the auxiliary ink table and that the
distributing rollers are always held above type-high so that they thoroughly
distribute the ink upon the auxiliary table without any danger whatever of
smearing the ink upon the type, while the form rollers are preferably slightly
below type-high, but as the bed reciprocates they in upon the auxiliary ink table,
receiving the ink which is thoroughly distributed, and then transfer the same to
the appropriate form upon the bed of the press.
It is frequently very difficult to properly and quickly adjust the sectional ink
ollers in line with the form which they are to uk since they are usually situated
either under the feed board or under the delivery tape, close to the impression
cylinder, in either of which cases, they are difficult of access, and in order to
obviate such difficulty and provide a incans whereby they may be readily and
quickly adjusted, provide upon que side of the uplight fiamug in the
construction shown in Figures 27 to 30 what I teim blind bearings g. Upon the
shaft of the sectional toller, Fig 29 I cut gauge 1ngs or grooves u',
preferably
que neat each end, which are to be aligned with the bearers d, upon the bed of
the press when the shaft of the ink roller is in proper place in its bearings To
adjust the roller, first place the shaft in the blind bearings g°, aligning the
gauge rings u, directly over and in the same vertical plane with the inner edges of
the bearers, d; I then slip the sectional rolle, in position over the form E,
and when accurately in line therewith, I clamp it securely to its shaft. I then
lift it out of the blind bearings and place it in its proper bearings, the grooves
aligning with the edge of the bed bearers, thus quickly and accurately adjusting
the said roller with reference to the form.
In some cases, it may be desued to print in two contrasting colors where the
colors will cover more than half the width of the press, and consequently it will

page_text: Hot be possible to arrange the forms side by side transversely of the bed of the
pices. In such case, aange the forms in line longitudinally of the press, as
shown in Figure 30 where it will be seen the two forms E and E' are so aanged,
and in order to ink these forins with the different colors without interference or
blending, I arrange the form rollers, a sufficient distance out from the impression
cylinder to prevent the form E, from coming in contact therewith in the extreme
movement of the bed to the tight, and I arrange the form rollers, on the
opposite side of the impression cylinder, a sufficient distance therefrom to just clear
he form E, in the extreme movement of the bed to the left, thus providing for the
uking of these forms by the rollers and, respectively, as the bed moves fust
in one direction and then m the other. The auxiliary ink table D', and the
other attachments are the same in this construction as in the former, the relative
angement of the forms and their rollers only being changed
Should the form rollers, be placed nearer the impression cylinder, the form
rollers,, must be moved further out towards the end of the travel of the bed. lu
both cases, the auxiliary table is detachably secured to the bed of the press, and
constitutes an attachment that can be quickly applied to any of the existing presses
of the type shown.
I am thus enabled to print two contrasting colors in close register from forms
placed longitudinally of the press, without raising or lowering the rollers The
paper is passed through the press in the usual way, and two colors printed thereon,
ns before; and it 18 then turned end for end and passed through the press again,
hereby the two colors are printed theicon in close register, while I effect the
same result with the forms arranged transversely of the press, as hereinbefore
described
"1
In applying my invention to bed and platen presses, commonly known to th
trade as jobber presses, whereby two or more contrasting colors may be punte.l
upon the common jobber press now on the market an attachment is provided which
can be readily and quickly applied to such jobber press without any alteration in
the same.
In printing contrasting colors on jobber presses, it has heretofore been the
common practice to use specially constructed presses for this purpose, and such
presses have therefore been ouly adapted foi the special purpose for which they
were constructed. Some of these presses now on the market are provided with two
dises or ink tables, ai ranged in the same plaue with each other, with mechanism for
operating the ink rollers so that one end of a job can be punted in contrasting
color with the other end, but a serious objection to these constructions lies in the
fact that they cannot be used without alteration for plain work My object is
chiefly to overcome this objection and my invention to that end consists in providing
an uk table arranged parallel to the ordinary ink table and in a different plane
thereto with mechanism to operate it, the whole constituting an attachment which
can be readily applied to the ordinary jobber press, in an improved means for
attaching the sectional ink rollers to the shaft, in a combination of parts whereby
contrasting colois may be either printed in parallel lines on in the same line, and for
accomplishing the purposes defined.
Releng now to Figmes 31 to 33 A indicates the frame of the press, C³, the
platen, C the chase, and Y the binckots or standards which support the ordinary
oh table composed of the inner and outer discs D' and D³, which are vibinted or
otated in opposite directions by the usual machams. The form king rollers are
operated by the crank dise F3, though the medium of the pitmen F and F³, in the
usual way which need not here be further described as it will be well understood
by those skilled in the ait and forms no part of my invention
Mounted upon the shafts s', are the sectional form rollers, and r, which are
adapted to ink respectively in the present instance, the colors "blue" and "red."
The rollers, are arranged to run in contact with the lower discs, while the
ollers are arranged to run in contact with the upper discs D' and D', and each
eet touches only the table to which it applies. The beatings of the rollers thus

page_text: always bear a fixed relation to the planes of the two ink tables, the rollet taking ink
from the upper table being movable only as it passes over the form.
In order to support the upper table in proper relation to the lower table, I
provide a supplemental frame Y, which is attached to the press by any suitable
menus. The upper surfaces of the sides of this frame form trucks upon which the
wheels T, on the outer end of the shaft scarying the rollers, are adapted to
travel so as to keep the said olleis in contact with the upper table D' aud out of
contact with, the lower table D'. These wheels are slightly greater i diameter
than the rollers which are themselves less in diameter than the distance between
the two tables. These supplementary ink rollers are thus movable with
respect to the ordinary form rollers and are raised by the wheels above the
lower ink table and into contact with the upper ink table, thus causing them
to take ink from the latter table only, the line of travel of the different sets of
rollers bening a fixed relation to the planes of the two uk tables Pivotally
supported upon lugs on the frame Y, is an aim Y, which carries the upper
table D and the mechanism for operating the same. Upon this aim and the
frame Y, are inclined lugs P, which are engaged by the jaws of the clamp H', held
in place by a set screw 10, thus fimly locking the arm, Y, to the frane, the clamp
resting against the lungs. When it is desired to throw the upper table out of use
temporarily, it is only necessary to remove this clamp and swing the arm carrying
the upper table and its operating mechanism out of the way, or the whole
attachment may be entirely removed. To operate the upper table, I provide
mechanism shewn in Figures 31 and 33 where, indicates a shaft mounted m
bearings, in the frame Y, and provided on its outer end with a ratchet wheel A¹³,
adapted to be intermittently operated by a pawl 2 on a level ", having a weight
on its outer end. This level is operatively connected by a rod g" preferably to the
pitman F and it is so timed that when the ink rollers are in contact with the
tables D D the shafts, will be stationary thereby holding the said tables
stationary. The shaft is 1otated when the rollers are inking the form, the upper
table D' being then rotated through the intervening gearing which consists of a
hevel wheels, on the lower end of a vertical sbaft s carried by the arın Y and
gearing with a corresponding wheel s" on the shaft 88. On the shaft are two
spur gears and h', transmitting motion to the discs D and D', respectively,
through the gears,, and ³, respectively. The gear, which engages with
the gear, to give motion to the disc D', ie preferably in the form of a cucular
rack and is mounted upon the upper face of the said disc while the gear ³, 13
secured to the shaft which carries the disc D, the idler 0, tiansmitting motion
from the gear h' to the gear has before described.
With the construction just described, it will be seen that two continsting colois
may be printed in parallel hoes, the rollers, receiving ink from the upper table
and the rollers, receiving uk from the lower table. Now if it is desired to print
contrasting colors in the same line on one after the other, I provide suitable tiachs
or cams for elevating and holding the different 1ollers out of contact with the form
while the other rolleis are in contact therewith, successively raising and depressing
the several 1ollers so as to print the colors one after another
This may be
accomplished by providing inetallic strips in the form of augle irons which
are adapted to be secured upon the chase or the frames, such irons being
made of the length desued and of sufficient depth to raise the rollers out of contact
with any particular portion of the form.
While I have shewn my attachment adapted to one form of jobber's press, it is
to be understood that it is equally applicable to other forms without inaterially
changing the essential features thereof which consist in the provision of an attach-
ment for jobber's presses, comprising an mk table adapted to be held above the
ordinary table and parallel thereto, with two or more sets of inking rollers a ranged
so that one set runs in contact with the lower table and the other set in contact
with the upper table.
My invention also comprises a tinting attachment shown in Figures 34 to 40 for

page_text: printing presses by which any portion of the paper may be tinted before it passes
to the impression mechanism whereby matter may be regularly printed upon a
colored background in a single run of the paper through the press
Around the outer edges of the impression cylinder C, metal bands a' are secured
at both culs in the recesses in the impression cylinder by neaus of suitable bolts,
01 set screws By loosening these set screws the tension upon the bands can be
eased, so that blocks on depressors a', having undercut grooves sliding upon the
bands may be adjusted to any point desired. This block a², fits snugly upon the
band and is held in place by the tension upon the band caused by tightening the set
Screw f
Projecting upwardly from each side of the frame of the press is an arm G', from
which is carried the king apparatus, consisting of the main toller Q, the
distributing rolleı a Ry the reservoir P, and the pivotted levert, carrying at one end
the transferring or form roller T', and at the other end the small wheel or rollei T,
adapted to be operated by the cam blocks or depressons a², as the impression
cylinder rotates. A suitable spring connecting the lever, with the fiame of the
ink apparatus, normally holds the transferring olle T in contact with the main
ink roller Q. The rollers n, are preferably given a vibratory inovement, by any
suitable menne, in order to secure a proper distribution of ink on the roller Q.
Around the edge of the impression cylinder, I preferably arrange a scale, for the
purpose of moro iendily adjusting the depressors a' in proper relation to the top of
the page
From the foregoing description, it will be seen that as the impression c
linder
rotates and the paper is fed around it, the depressor a³, comes in contact with the
roller T and aises the said 1oller, thereby depressing the transfering roller T,
until it comes in contact with the paper upon which it tiots a background in length
corresponding to the length of the cam block a', and in width corresponding to the
width of the roller T. In the further rotation of the impression cylinder the
impression to be taken will be made from the paper and that portion which has
been tinted will appear in the proper place upon the page or colunin in contrast to
the rest of the paper
It is understood that the transferring roller T', may be of any length desired and
that it is not necessary to have the inking apparatus extend the full length of the
impression cylinder, for it is obvious that the frame supporting this apparatus may
be of such width as will be sufficient to can rollers of the length desued
frames supporting the ink apparatus may in such case be separate from the main.
frame of the press and suitably bolted on clamped to the aims G.
The
The arms on each side of the press may support a cross bar, upon which the
fiame O, of the inking apparatus is clamped by jaws and along which the whole
inking apparatus can be slid so as to bring the form roller T, over the proper
column or columns intended to be tinted In such case, the rollers T', should be
supported upon a shaft extending entirely nero-s the impression cylinder, and
splined or otherwise suitably mounted in the levers t, so that the latte may move
longitudinally thereof as the inh mechanism is adjusted to the desired position.
Refening now to Figures 35 to 40, wlach illustrate my invention applied to a
perfecting press, I mount in the frame above the punting cylinders, the shaft R,
upon which is splined a cam wheel N', provided on each side with flanges having
undercut grooves n'. A seginental curved plate N, having bevelled edges is
adapted to fit between the Hanges of this wheel and is adjustable laterally on the
wheel by set screws n', having bevelled ends contacting with the bevelled edges
of the plate This plate is provided with projections N³, forming sutlaces for
receiving the color fiom the king apparatus, and it has also, cast upon its
surface, cam projections N, which are adapted to operate the rollers T, for
depressing the transferring roller T', into contact with the punting surfaces N³,
in a similar manner to that described with reference to Figue 3 The length
of the cams N, must be equal to the length of the printing surface at N³, and
when two or more tints are to be made, the cams N' should be arranged as shewn,

page_text: Figure 40, so that each one will operate its proper roller T, and the distance of
the printing surface N', from the respective cams N, must of course, be equal to the
distance between the arcs descubed by the rollers Tan T
Upon the end of the shaft R, 13 a spur wheel P, meshing with the wheel P. on
the end of the shift carving the impression cylinder C The type cylinder C, 19
provided with a spur wheel 1, meshing with the wheel P, this cyller being of
course, out of contact with the cam wheel N'. When it is desire to tat the
paper as it passes around the impression cylinder C, the segmental plite N³, 19
provided with printing surfaces N³, of the deaned length and width and
conresponding cains N The plate is then placed around the cam wheel between
the flanges and adjusted laterally by the set screws and moved circumferentially
until the printing surfaces are in
scale on the sunlace of the cam wheel, a position in respect to the top of the column, a
as shown in Fig 37 in proper units indicating
the position of the end of the cain plate for the different distances from the top of
the columu. The cam wheel is laterally movable on its shaft, being seemed in
position by any suitable means, ns by set screws passing through the hubs, it can
thus be movel laterally of the impression cylinder and placed in position to tint any
desired portion transversely of the page.
The operation of the attachment applied to the perfecting press will be readily
understood from this description, as it is in all respects similar to the operation of
the device attached to the bed and cylinder press
The king rollers are preferably operated by gearing meshing with the circulai
1ack upon the impression cylinder, but they may be operated by any convenient
means, as for instance in presses that do not have the rack on the impression
cylinder, they may be worked by friction wheels, belt and pulley, or chain and
sprocket wheel on the like.

vlinder normally held above type-high, each of the said tollers having a separate
mk supply and separate ink distributing rollers, the form from which a plurality
of colors is to be punted, strips of standard lengths secured to the bed of the press
by the usual furniture and arranged to positively throw the color ink rollers into
contact with the type in the form, at predetermined points in the travel of the bed,
and springs for holding the color ink rollers normally above type-high, whereby
various colors may be printed from ordinary type at one unpression, substantially
as herembefore descubed.
6 Tu a multi-color printing press, the combination with the bed and form
thier con, of the frames attached to a transverse bai, a main ink roller jou nalled in
the said frames, means for feeding and distributing ink on the said roller, a
supplementary hanger or frame attached to the transveise bar outside of the
inkers, a color ink rolle normally held in contact with the main ink roller, and
above type-high, a rock shaft joutnalled in bearings in the supplementary hanger
and frames of the inhing apparatus, connections between the said lock shaft and
colo ink roller, and connections between the bed of the press and the rock shaft,
licieby the latter may be vibrated at predetermined points in the travel of the
bed to cause the color ink roller to ink the form, substantially as herembefore
described.
7 The combination with the bed and impression cylinder of a printing press for
multi-colour printing, of an auxiliary ink table, detachably secured to one end of
the bed, a supplemental frame situated on one side of the impression cylinder, form
Tollers mcunted in bearings on the frame of the press having their lower surfaces
at, or slightly below, type-high, distributing rollers journalled in the supplemental
frame, a form on the bed of the press aligning with the said rollers, a second set of
form rollers on the other side of the impression cylinder receiving ink from the
oidinary ink table, a second form in line with the first form and receiving ink from
the latter rollers, substantially as hereinbefore described.
8. In a printing press for multi-colour printing, the combination with the ink
table, the form and form rollers of a chromatic printing attachment consisting of
an ink table removably secured to the piess parallel to and above the ordinary ink
table of the press, a supplementary set of form rollers whose line of travel bears a
bxed relation to the planes of the ink tables and arranged to take mk from the
upper table, with means for raising the said rollers to contact with the upper
table and out of contact with the lower table, substantially as hereinbefore
described.
9. In a printing press for multi-colour printing, a tinting mechanism consisting
of a rotative part, a colour inking apparatus adjacent to the framo of the press, n
lever fulcrumed on the said appaiatus and having an uking roller Journalled on
one aim thereof, normally hold out of contact with the rotative part, and cams
situated upon the said rotative part, adapted to engage the other arm of the said
lever to raise the same and depress the color uk roller, at predetermined points.
substantially as herein before described.
10. The combination with the impression cylinder of a printing press for multi-
color printing, of a flanged wheel seemed to a shaft above and rotating with the
said cylinder, a segmental curved plate mounted on the wheel and provided with
a raised surface or raised surfaces for receiving uk, and a corresponding cam
projection or corresponding cam projections thereon, one or more inking apparatus
supported around the periphery of the end wheel, a lever fulcrumed on each of the
said inking apparatus, an inking roller jonnalled on one arm of each lever, the other
aim of each lever being adapted to be raised by its corresponding cam projection
on the segmental plate eo as to depress the roller into contact with its corie-
sponding ink receiving surface, substantially as hereinhefore described.
11. The herem described improvement in the art of multi-colour printing which

page_text: consists in arranging two or more forms in sets of two transversely with respect to
the line of movement of the inking devices, causing oue of the forms of each set to
be inked by a single inking device carrying a single color or a plurality of inking
devices carrying a plurality of colors, and causing the other form of each set to be
mked by a plurality of inking devices carrying a plurality of colors, then printing
simultaneously from all the forms upon a single sheet and finally shifting the sheet
and printing again to that the second impression of each set will be in close register
with the first unpression thereof, substantially as and for the purpose set forth
withr eference to Fig 26 of the accompanying drawings.
12. The beien described improvement in the art of multi-color printing which
consists in arranging primary and secondary forms in line upon the bed of a press,
causing the primary forms to be inked by a single inking device or a plurality
of inking devices, and causing the secondary forms to be inked by a plurality of
inking devices, printing simultaneously from all the forms on a single sheet,
shifting the sheet and again printing so that each impression made at oue passage
through the piesa receives a complementary impression on the next passage
therethrough, substantially as her embefore described.
