This invention has reference to printing presses; and comprises the following
novel features, that is to say, a double frisket through which the continuous web
of paper is passed; two rotating and reciprocating heads one of which carries the
type and the other the "make ready;" and the combining with the reciprocating
type head, an inking wheel adapted to ink type on the head with a different color
at each reciprocation. It also comprises various details of construction all of which
are fully set forth in the following specification and shown in the accompanying
drawing which forms part thereof.
The object of this invention is the performance of the work technically known
as color printing, by causing the paper to be held stationary while the different
colors are printed thereon by the type which changes to insure a perfect' register
and prevent all accidental lapping of the colors as is always the case when the
paper is handled two or more times before the print is completed. This invention
is particularly adapted to print book-backs, and for almanacks and pamphlets
generally, and would be used in connection with the book printing and binding
machine described in the specification of Letters Patent dated April 18th 1882.

A is the frame of the machine. B is the main shaft which carries the two cam

page_text: wheels B¹ provided with cam grooves b 61; it also carries the fast and loose
pulleys B2 B3, and spur wheel e. CC are the two reciprocating heads one of
which C carries the type or colour blocks 0 and the other C₁ the make ready
pads C³. These heads are made polygonal as shown and may have as many faces
as desired, each of the said faces corresponding to a color. Each of the color
blocks C has its own make ready C³ so that in printing, I obtain perfect
registration and also the best impressions. These heads CC' are respectively
pivoted or journalled to arms D D at c c³, and the said arms are loosely, hinged
to their shafts E E¹.
Each of said arms is provided with a friction roller & which works in the cam
grooves b b of wheels B; these cam grooves are adapted to draw the two
heads CC together, hold them in contact for an instant of time, then separate
them and hold them away from each other for a short interval of time, then force
them together again, and so on continuously, said heads making two reciprocations
for every revolution of the cam wheels B'. While these heads are being moved
apart they are intermittently rotated so as to bring a fresh color block C² and
make ready C³ in printing position by means of the pins U on the revolving
dises U working in slots or grooves C in said heads. These discs U₁ should revolve
twice as fast as the cam wheels B¹. They are rotated by mitre wheels V, shafts V',
mitre wheels W, shafts E E' and spur wheels e ele es but I do not limit myself
to this mechanism as there are many ways of accomplishing the same result. The
discs U¹ are carried by arms D D₁ and do not change their relative position with
respect to their own heads C C¹.
Arranged between the heads is my improved frisket which consists of two plates I
provided with one or more perforations I¹ for the type prints which are supported
very close to each other by frames J and between which the paper to be printed is
fed, as shown in Figure 1 and Figure 3. If desired the ends of the parts I may be
curved outward as at i to prevent any possibility of the catching of the paper.
The color blocks C enter the apertures in one plate I and the make ready
blocks C³ enter the apertures in the other plate I. The roll of paper K is supported
upon an axle K and the web lc fed between tension rollers L, then is inter-
mittently fed to the frisket by the adjustable feed discs M having their sides
notched and being adjusted by means of the slots m and bolts m¹ so that any
desired length of sheet may be fed. The feed mechanism is fully described in the
former, specification. These discs are adapted to make a half revolution after the
heads CC have made one revolution upon their axes c c¹. After the paper passes
through the frisket it is fed between rollers :N to the knife P which is actuated

paper is cut, it falls on the fly frame Q which is actuated by the rod Q¹ and cam R,
to lay the printed paper upon the table R¹
Other suitable mechanism may be used to operate the knife and fly frame.
When the head is moved away from the frisket by the part b, of the cam
wheel B¹, the pin U enters a curved groove C in this head, and quickly turns it to
the proper position to bring the next color block into position for printing. After
turning the head the pin moves in the said groove which is concentric with the
axis of the wheel or disc U¹, hence the pin then acts. to steady the head. The
moment the head is turned a sixth or an eighth of a revolution the next color
block C reaches the inking wheel. The inking wheel is fast to a shaft T with
which it revolves, and is provided with as many sets of color rolls t as there are
color blocks C and these rolls t are guided by rails SS, the latter of which are
straight as shown, so as to guide the inking rolls in a straight line to ink the
color block. These straight guides S¹ may be adjusted by means of slots; & and
bolts s¹ or by other means. If the head C has six color blocks C2, then with every
reciprocation of the head the inking wheel rotates one sixth of a revolution, so, as
to run one set of color rolls t across the face of the color block corresponding with
the said color, and when it is at rest and under the action of the concentric part. 61
of the cam wheel B.

pawl T¹ cam T2 and roller T³, or other suitable mechanism.

The operation of the said machine is as follows: as the shaft B is rotated; the
cam-wheels B¹ force the heads C C apart and during such movement the pins U
cause a partial rotation of the heads bringing a fresh set of color blocks and make
readies into printing position. At the end of the outward throw of the heads the
head C containing the type or color blocks C² rests against the inking wheel frame.
At this instant one set of inking rollers t is caused to pass from one side of the
guide S to the other, being guided upon the flat guides Sover the face of the type
or colour block. The inking wheel then ceases to rotate, and is in position to ink
the next color block or type with another colored ink.
In these arrangements each color block has its own particular inking rolls so as
not to mix the colors, but if desired when I employ a duplicate.set of color blocks
there may only be one half the number of inking rollers.
As the cam wheels B¹ still rotate the heads are drawn together and print upon
the paper k held in the double frisket. This operation is repeated until all of the
color blocks have printed, then the feed wheels or discs M feed the paper along
through the frisket, and during the next printing the knife P. cuts off the printed,
part which falls upon the fly frame Q, and is laid upon the table R¹.
By the use of the double frisket and reciprocating printing head adapted to
intermittant rotation I am enabled to print two or more colors without moving the
paper thereby insuring the most perfect register. The adjustable guide S' regulates
the pressure of the inking rollers upon the color blocks.
Having thus fully described the said invention as communicated to me by my
foreign correspondent and the manner of performing the same, I wish it understood.
