5 Claims. (Cl. 41-1)
‘This invention relates to a method and appa
ratus for printing. More particularly, the inven
tion relates to a method and apparatus for multi
color printing, in which the borders or outlines
f5 between the various colors, applied in any suit
able manner, are softened, and the colors applied
to adjacent areas are `intermingled along their
My invention is designed particularly for ap
10 plication in the printing of floor coverings, e. g.,
duce the desired drawing out or blending of the
`In the accompanying drawings, I have shown
the significant parts of a standard printing ma
chine as modified to embody my‘invention, and
which may be used for carrying out the method
of my invention.
This is shown as an example,
and for purposes of illustration only, and is not
to be taken as limiting the invention in any way.
Fig. 1l is `a fragmentary side elevation of a „
in the printing of linoleum or felt base goods
with oil paints, and will~ therefore be described in
connection therewith although it is to be under»
standard printing machine modiíied to embody
the present invention;
stood that the invention is not limited to any
printing machine illustrated in Fig. 1; and
Figs. 3a to 3f show in plan view a set of blocks
suitable for use in carrying out my invention.
As already pointed out above, my invention
contemplates the bringing of a suitable blending
surface into >Contact with a wet color upon the
printed goods, and while thus in contact shifting 20
the vblending surface laterally. In the case of
floor covering materials printed upon an ordinary
block printing machine, this is most easily ac
complished by means of a mash block attached
to one of the printing ‘heads of the standard 25
such specific application.
In the printing of floor covering materials such
as linoleurn and felt base goods, the various col
ors fareapplied to the adjacent pattern areas at
successive positions, and by separate printing
20 blocks which, after Abeing supplied with paint,
e. g., from a roller fountain >or paint carriage,
are moved toward the goods until the paint is
transferred from the s-urface of the block to the
surface of the goods. In order to assure even
distribution of the paint and avoid excessive suc
tion and irregularity or smearing of the paint
due to such suction, the blocks are ordinarily
made with projections, e. g., by making parallel
saw cuts in one direction or at righ't angles, `so
30 as to form on the surface of the block parallel
lines or rows of `pins separated by kerfs. 'I'he
formation of the designs is limited to a substan
tial extent by the arrangement of these lines or
pins, and in the formation of patterns which de
pend upon irregular lines; and particularly pat
terns such as imitation marble, etc., narrow lines
of color are apt to follow too regularly the recti

machine, provided that suitable provision is made
for lateral motion of the printing block when it
has been moved into contact vwith the wet color.
rI‘his may `be accomplished in numerous ways.
One mechanism suitable for this purpose is
shown, for example, in the Waldron Patent No.
811,342. In Figs. 1 and 2, I have shown the
mechanism which I prefer to use for this purpose.
In these figures, the printing head I0, the
frame ii, i2, the head operating mechanism I3, 3
lli, and the other parts of the machine not
specifically referred to below may be substantially
linear arrangement of the lines or pins on the
identical with those in common use. In the pres
ent case, the `hole 2t through which the bolt 2i
It is an object of the present invention to pro- . passes to support the printing head if! on the
vide for irregularly drawing out colors, either
operating bar ill is slotted, as shown in Fig. 2,
at »a <‘border or narrow lines of color, where the
to allow a lateral shifting of the head relative to
pattern :makes it desirable that the color should
not follow any regular rectilinear arrangement.
45 Another object of the invention is to produce ir
regular and limited blending of colors applied to
the‘surface of the goods.
With these and other objects in view, the in
vention consists in first applying the various col
ors to the goods in any suitable manner, e. g.,
as has been‘commonly practiced in the prior art,
and thereafter moving a surface or surfaces into
contactwith the wet colors upon the goods, and
while said surfaces are in adhering‘contact with
the colors, moving them laterally so as to' pro
the operating bar I4. A shifting mechanism is
provided to effect the lateral shifting of the head 45
at the proper time with reference to the opera
tion of the machine, In the present case, this is
elected by means of a cam 22 secured to the cam
ii'hfor its shaft, and having a high point 23 sub
stantially `at `the >middle of the low part of the
cam I3.
The cam follower 24 rides upon the
cam ,22, and is held aligned therewith by the
guides 2.5, and 2E. The roller 2l on the follower
2'4 contacts with a lever `28 pivotally secured to
the frame of the machine kby a bracket 29. The
upper portion of this lever 28 vbears against the
printing head lll, as shown at 30.
The shifting mechanism just described may be
repeated at the opposite side of the head, with
the high point 23 of the cams at the two sides
staggered so that the head is shifted ñrst to one
direction, and then back; or the head may be
resiliently held in one direction so that when the
high point 23 of the cam 22 moves out from
under the follower 24, the printing head will re
turn of its own accord.
In Figs. 3a to 3f, I have shown by way of illus
tration a set of blocks which may be used, for
example, in printing marble tile patterns.
15 block 3| prints the veining in one color, the block
32 prints veining of another color, the block 33
prints veining of still another color, block 34
prints on alternate squares of a tile pattern a
base color, and the block 35 prints a different
20 base color upon the intervening squares of the
pattern. When these five blocks have printed on
the goods, the alternate squares of the tile pat
tern will each have a pattern in which the vein
ing applied by the blocks 3|, 32 and 33 has run
through the paint applied by the blocks 34 and
35 to the surface. Since the paint applied by the
blocks 34 and 35, however, will have been ap
plied in ridges or in dots because of the lines or
pins of the blocks, the veining will tend to come
30 through in lines parallel to the lines or rows of
In order to destroy this rectilinear character
of the veining, the block 36 is moved into contact
with the wet paint and then shifted laterally,
35 e. g., ,Jg or 1A; of an inch. This lateral shifting
of the head according to my invention is intended
only to blend and soften the fine outline of with
out destroying the pattern or rendering it un
recognizable as such. The amplitude may be
40 substantially varied, but ordinarily should not
be more than about three times the width of the
projection of the block by which the color is ap
As shown in Fig. 3f, the block 36 is cut away
45 along narrow strips 31 and 36, so that it will not
contact with the paint along the borders between
the squares of -the tile pattern. Thus, the pat
tern within each square will be softened and
blended and drawn out from the rectilinear ar
50 rangement, while the borders between the tile
patterns may remain clear and sharp.
Ordinarily it would be more convenient to con
struct the machine so that the block is moved
laterally and back again before it is withdrawn
55 from the color, but it is to be understood that the
lateral movement may be in one direction only,
and if desired, the cam which effects the lateral
movement may operate at half the speed of the
machine cam I3 and be shaped so that the block
60 moves in one direction when in contact with one
section of the goods, and in the opposite direc
tion when in contact with the next section. In
this way, an appreciable variation in the repeats
may be obtained.
In Figs. 3a to 3f, I have shown an arrangement
of blocks, and have described above an operation
in which the veining is applied before the ground
color, as described and claimed in Patent No.
1,924,501, of Bernard J. Kelly. It is to be under
70 stood, however, that the present invention is ap
plicable to other types of patterns, Whether made
by overlay printing or by cut-out in which only
one block applies a color to each of adjacent areas
and the blending is entirely across the border,
75 instead of being partly a horizontal and partly
a vertical blending, as in the case of overlay
or underlay printing.
’I'he blending surfaces of the block 36 may be
the ordinary pin or line blocks, or may be brush
blocks, as described and claimed in the co-pend
ing application of Bernard J. Kelly and James
W. Kemmler, Serial No. 626,593, filed July 30,
1932 which has matured as Patent Number
2,052,350, or may be screen blocks, as described
and claimed in the co-pending application of
Rollin C. Gere, Serial No. 677,816, filed June 27,
1933 which has matured as Patent Number
1,996,916. If suitable provision is made for sep
aration, e. g., by forming with a convex surface,
the areas between the channels 3l and 38 may
even be solid.
I have found that most pleasing results are ob
tained when the movement of the blocks is ap
proximately ¿E to 1/8 of an inch. The invention,
however, is not limited to any particular ampli 20
tude, and with other types of designs, a much
greater lateral shifting of the block may pro
duce more desirable results.
It is contemplated
by the present invention that the lateral shift
ing shall- draw out one color from the border
to which it was initially applied, and depending
upon the pattern which is desired, the drawing
out, and consequently the lateral shifting, may
be greater or less. It is not intended, however,
that the shifting be carried to such an extent 30
that the pattern is completely destroyed, but
rather that the pattern should be developed or
softened without being rendered entirely un
While I have described above and shown in the
drawings certain specific embodiments of my in
vention and certain manners of procedure, it is
to be understood that the invention is in no Way
limited to these particular constructions and pro
cedures, but, on the contrary, numerous other 40
changes and modifications will suggest them
selves to those skilled in the art, and all such are
to be included within the scope of this applica
What I claim is:

comprises depositing different liquid colors upon
adjacent areas of a sheet material so as to be
capable of flowing thereon, moving a block hav
ing spaced projections into contact with said 50
colors, moving said projections laterally while

color across its border and irregularly into an
other, and removing said projections from the
2. 'I'he method of blending the outlines of a
pattern printed with liquid colors capable of
flowing upon the surface to which they are ap

against the surface of the wet colors forming the
pattern, and, while the block is thus in contact
with the color, shifting it laterally a limited dis
tance suñicient only to draw at least one color
across its border, thereby to blend and soften the
ñne outlines of the pattern Without destroying it 65
or rendering it unrecognizable as such.
3. The method of printing patterns having soft
blended outlines which comprises printing differ
