Improvements in Methods of and Apparatus for Coloring or
Printing Yarns.
I, CHARLES LUDWIG HORACK, Civil Engineer, of 50, Livingston Street, City of
New York, Borough of Brooklyn, Kings County, State of New York, United States
of America, do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:.
My invention refers to methods of and apparatus for coloring or printing yarns,
and more particularly yarns used in the manufacture of tapestry and velvet
carpets.
My improved method is capable of being carried out wholly or partly by means
of appliances actuated directly by the hands of the operators or by mechanical
and automatic means superintended and directed in general only by the operator.
In the latter case I prefer to employ an apparatus as now commonly used in
printing such carpet yarns, 'which consists of a drum around which the yarn is
wound and a color carriage with color-wheel adapted to apply streaks of color to
the yarn side by side while traveling underneath the druni and to apply thereto
the structural improvements above referred to.
The objects of my invention are to provide suitable methods for applying color-
ing, matter to yarn and for spreading and forcing such coloring matter along, into,
and through the yarn, and to thereby distribute such coloring matter in
approximately uniform manner, or approximately equalize the same, whereby,
particularly also after the yarn shall have been subjected to the usual steaming or
Scouring process, and after having been woven into a fabric, portions of threads of
the same shade may be made to appear substantially uniform..
Further objects of my invention are to provide suitable, spreading rubbing or
scraping devices in such proper relations with the-color wheel that the method
above referred to may be properly carried out automatically with the aid of such
appliances and that color applied to the yarn in streaks by said wheel may be
distributed over and through the yarn in approximately uniform manner, so that
after such yarn has been subjected to the usual steaming and scouring processes,,
and after it has been woven into the fabric, it shall appear substantially uniform in
shades and colors throughout.

Further objects are to provide proper means for varying the positions of such
spreading or scraping means with reference to each other so as to be able to not
only place and maintain the same in such relative positions in regard to each other
and to the color wheel as will permit of their simultaneously covering outer ridges
of successive streaks in a series of streaks of the same color, but of also covering
single streaks, and the first and last streaks only in such a series, without necessarily
overlapping adjoining streaks:
Further objects are to provide proper means for readily adjusting the apparatus
so as to permit while alternately using color wheels of different widths of the use
of the spreading devices proportioned accordingly.
I accomplish these and other useful objects by the methods and means hereinafter
described and set forth more particularly in the claims.
In the accompanying drawings forming part of this specification, and where in
like letters of reference refer to corresponding parts, Fig. 1 is a side elevation,
partly in section, of an apparatus constructed according to my invention, the
color carriage being placed in a position near the end of the drum, where the
shifting of the spreaders and automatic releasing of a device for locking the color
drum in its proper position takes place; Fig. 2 being a side elevation of portion
of the releasing mechanism near the left hand end of the drum which co-acts
with portion of such device shown at the right hand end of the drum in Fig. 1.
Fig. 3 is a ground plan of Fig. 1, the drum being omitted as well as the drip pan
underneath the left hand spreader. Fig. 4 is an end view of Fig. 1, looking
towards the left, and Fig. 5 a ground plan of the track carrying the color carriage
and of shifting blocks and devices employed in operating said blocks for the
purpose of adjusting the positions of the spreaders. Figs. 6, 7 and 8 are
diagrammatic representations in plan views of different relative positions in which
the color wheel and the spreaders may be placed in an apparatus above referred to.
Fig. 9 shows a vertical section of the lower portion of the supporting device of
the spreader doing away with certain features of the corresponding supporting
device illustrated in Figs. 1, 2 and 3. Figs. 10 and 12 are diagrammatic repre-
sentations in ground plan of color wheel and spreaders so arranged with reference
to each other as to illustrate some of the features of my invention, Figs. 11 and 13
being corresponding side elevations. Fig. 14 is a horizontal section along
line 14, 14, in Fig. 1, and is drawn to a larger scale than Figs. 1, 2, 3, 4 and 9.
In carrying out my invention I prefer to employ a color carriage 12, mounted
on wheels 8, 8, and 10, 10, on which carriage color box 1 and color wheel 23 are
supported, and which is drawn by means of a cord attached to hooks 30 forward
and backward along rails 32 placed underneath and parallel with drum 33
carrying the yarn Y, all in usual manner, for the purpose of thus causing the
periphery of the color wheel to apply to the yarn on the drum streaks of color
side by side, the arrangement of such streaks with reference to each other as to
color and shade being in accordance with the design or pattern to be produced in
a tapestry or velvet carpet.
The color wheel in travelling forward and backward along the drum successively
applies streaks of coloring matter to the yarn, the drum being partially revolved
after the production of each streak, so as to bring the yarn in proper position
to receive the next streak, successive streaks being indicated by St, S3, S5
(streaks S and S3 in Fig. 3 being shown only to indicate the relative
position of such streaks after the color carriage shall have travelled
towards the left sufficiently to assume a position underneath the yarn
on the drum), the wheel in making each streak producing ridges of
coloring matter rl, 2, 3, 7, &c. along its path, while at the same time forcing the
coloring matter into and through the yarn between said ridges. Where at each
step the periphery of the drum is swung to a sufficiently greater extent than the
width of the operative edge of the color wheel amounts to, two ridges as 2 and 3
may be produced during successive printing operations separate and distinct from
each other, as shown in the drawings, while where the peripheral throw of the

page_text: drum at each step is but slightly in excess of or substantially corresponds with
such width of the color wheel such adjoining ridges as r³ and will be apt to run
into each other and to be consolidated into one ridge. It is the coloring matter
forming these ridges which particularly requires to be distributed laterally and
to be forced into the yarn, the comparatively small amount of color between the
ridges generally entering into the yarn more thoroughly under the heavy pressure
exerted by the color wheel.
prefer to employ for such purpose appliances constructed as follows: Referring
first to the mechanism attached to the right hand end of the carriage 40 is a
bracket secured to the carriage, such bracket carrying an upright standard 41
which contains a vertical channel as 42, 43 is an upright post adapted to slide
laterally within said channel without changing its position vertically and without
tilting. 44 is an arm extending from the top of post 43 forward and upward to-
wards the color wheel, and containing at its upper end a vertical recess 45 within
which a spiral spring 46 is inserted. 47 is a spreader or rubber adapted to travel
along the drum, its upper operative surface being of substantially the width of one
of the streaks, and its under side being constructed as a cap, telescoping over the
upper portion of arm 44 in such manner as to be actuated by and to actuato
spring 46, as the scraper travels along the yarn on the drum and accommodates
itself to such variations as may occur therein. The underside of arm 44 is made
to slide along the upper surface of standard 41 and pin 48 inserted in the lower
portion of post 43 is made to slide along the lower surface of said standard, thus
preventing longitudinal displacement of said post within said standard. The
rear face of post 43 is provided with vertical grooves as a, b, c, d, e, f, g, h
and &c. (Fig. 14) into either of which fits the wedge shaped front portion of
bar 49 in such manner that when such bar is being pressed forward it will
normally confine said post and with spreader 47 firmly in its corresponding
position. This forward pressure is produced by a leaf spring 50 resting against
the rear face of bar 49 and inserted within vertical channel 51 in the rear portion
of standard 41, said bar and said spring being confined therein by means of cover
plate 52 screwed to the rear face of standard 41. 53, 53 are spiral springs inserted
in proper sockets 54 in post 43 and in corresponding cylindrical channels 55 in
the side walls of standard 41 the outer ends of such channels being closed by screw
threaded plugs 56. These springs yieldingly resist lateral displacements of post 43,
so as to avoid abrupt movements of the same. 57 is a bracket extending rearward
from the upper and lower portions of standard 41, and 58 a lever fulcrumed to
said bracket by means of a detachable bolt 59 with proper nuts, passing through
proper corresponding perforations h and i in said parts. The upper portion of
lever 58 extends forward over post 43 in such manner as to be capable of swinging
along its upper surface, a pin 60, preferably in screw thread engagement with
post 43, and in sufficient free engagement with said lever serving to so couple
together said lever and said post as to impart lateral movement of the former to
the latter in such manner that as the foot of lever 58 is being swung to the left, the
spreader 47 will be moved to the right and vice versa. 60 is a pan for receiving
and for carrying off if desired surplus coloring matter removed from the yarn by
the spreader, which might otherwise flow into channel 42. The same is secured to
At the left hand
lever 58 by pin 60 and moves with said lever and with post 43.
end of the color carriage corresponding appliances are provided indicated by
numerals 40, 411, &c.
When a single streak or the first of a series of streaks is to be made, overlapping
of the spreader over an adjoining streak of different color should be prevented
and for that purpose spreaders 47 and 47' are placed in the positions shown in
Fig. 6 by so swinging levers 58 and 58' as to make bar 49 co-act with notch f
in post 43 and a corresponding bar at the other end of the carriage with a corre-
sponding notch in post 431, the formation of notches a, b, c, &c. and of the portion
of r 49 fitting into the same being such that upon vigorous side-ward pressure
upon said post in either direction bar 49 will temporarily recede from the notch

page_text: with which it may be in engagement and will pass through subsequent notches
until post 43 comes to rest when said bar will enter a corresponding notch and will
lock said post in position owing to the action of spring 50. While occupying the
relative positions illustrated in Fig. 6 (the arrows wherever applied to the color
wheel illustrating the direction in which it is moving at the time) spreader 47 is
travelling in front of the color wheel over the portion of white yarn to be covered
directly afterwards by said wheel, while spreader 47' is covering the entire streak S¹
then in course of application. While streak S is being made I prefer to give
to the spreaders the relative positions shown in full lines in Fig. 7 wherein the
spreader 47 in the rear of the color wheel is made to cover the larger portion of
streak S3 and the smaller adjoining portion of S₁ thus covering ridges and 3 and
spreading color from the same laterally while spreader 471 is made to cover
the larger portion of streak S¹ and extending over into the space to be traversed
directly by the color wheel and to be then occupied by streak S³, sufficiently to
force color from ridge 2 into the space to be occupied by ridge 3, thus moistening
that portion of the yarn and forcing color into it and making it receptive for the
color in said streak 3. In afterwards making streak S3 I reverse the relative
positions of the spreaders as illustrated in full lines in Fig. 8, spreader 47 thus
acting with reference to streak S as spreader 471 did during the making of the
previous streak with reference to streak S¹, and spreader 471 acting with reference
to S³, as 47 did previously with reference to S³. A subsequent streak S would be
treated in the same manner as S3, &c.
The vertical grooves in post 43 are so proportioned that when spreader 47
occupies the position shown in Figs. 3 and 7 bar 49 will co-act with groove e, and
when occupying the position shown in Fig. 8 said bar will co-act with groove b.
This condition is illustrated in Fig. 14, the proper relative position of spreader 471
being produced by shifting of its post 431 in analogous manner. I prefer the
relative alignments of spreaders as above described, because the edges of the
spreaders in the positions shown in Figs. 7 and 8 (which are the positions generally
occupied by them) do not coincide and hence sharp lines in the color which might
be produced by the edge of one spreader may then be equalized by the other. It
will be seen that under said alignments, the color in interior streaks in a series
of streaks, will receive two rubbings by the spreaders in opposite directions and
thus thorough saturation of the yarn by the color may be accomplished, whereby
with the aid of the usual subsequent steaming and scouring processes the yarn will
receive its proper colors and shading. This is particularly important with reference
to interior portions of streaks, as color must be first transferred thereto laterally
from the outer edges of the streaks and must therefore be rubbed into the same
in thorough manner. However, I do not wish to confine myself to the relative
alignments above described, as good results may be obtained with other alignments.
Thus, instead of the alignments shown in Figures 7 and 8 in full lines the spreaders
might be placed in the positions shown in broken lines in said figures and indicated
by 147 and 147, in which case cach spreader is made to cover a complete streak.
By the rubbing and re-rubbing of the yarn by means of spreaders of single
widths I am enabled to obtain advantages heretofore only secured by the employ-
ment of spreaders of double widths. Thus such single spreaders will accommodate
themselves better to the unevennesses which frequently occur on the surfaces of
yarn drums. Besides, under my invention as described I am enabled to auto-
matically rub and equalize single streaks, which cannot be accomplished with
automatic spreaders of double width.
For the purpose of alternately placing the spreaders into the positions illustrated
in full lines in Figs. 6, 7 and 8, after swinging the drum in each case into its proper
new position, I prefer to employ shifting means as follows: The lower ex-
tremities A of lever 58, and B of lever 581 preferably made cylindrical are adapted
to travel along suitable shifting blocks C, D, E and F placed between the track 5
rails as shown more particularly in Fig. 5. When spreader 47 is to be moved from
its position shown in Fig. 8 to that shown in Fig. 7, foot A has to be moved in the

page_text: opposite direction, and this is accomplished by guiding said foot along slanting
surface c of block C from its position A' to its new position A2 in the direction of
the arrow. While spreader 47 is placed as in Fig. 7 lever foot A will travel from A2
to A³ where it will engage with surface don block D and will be guided along
said surface d to position A which corresponds with the alignment of position A',
to which position foot A is returned upon the return travel of the carriage. In
positions A2 and A4 foot A just clears the shifting blocks laterally and thus, after
proper locking of post 43 has occurred when foot A reaches either of said positions
without any further shifting taking place, the lateral shifting of post 43 being
solely due to the sideward thrust upon lever 58 imparted to it during the travel
of foot A along surfaces c¹ and d¹ respectively. If, however, for any reason proper
locking of post 43 should not have occurred at positions and A4 and foot A
during such further travel of the color carriage in the same direction should have a
tendency to swing backward, the outer slanting surfaces and of blocks C
and I would, on the return trip again forcé foot A into its proper position and
then secure proper locking of post 43. The shifting of foot B of lever 58' is
accomplished in analogous manner, the travel of foot B being indicated by
course 1, B2, B3, B4, while spreader 47' moves from the position shown in Fig. 8
to that in Fig. 7 and back again, such shifting being accomplished by means of
shifting blocks E and F provided with proper guiding surfaces el, e² and f¹, f
respectively. Shifting blocks C and E are placed near the right hand end of the
yarn drum and blocks D and F near the left hand end in such positions that
blocks E and D will compel the lateral shifting of the spreaders promptly after the
spreader nearest to the drum has passed from underneath it. When the spreaders are
to be moved from either of the positions shown in Figs. 7 and 8 to those shown in
Fig. 6, I employ the following apparatus: J and K are two longitudinal bars
placed between rails 32, 32, higher than the shifting blocks and joined together by
tie pieces L. Shifting blocks C and F are stationary, while blocks E and D are
firmly secured to corresponding tie pieces L in such manner that upon lateral
movement of said bars into their extreme opposite positions J and K¹, shown in
dotted lines in Fig. 5, said blocks will move with the same. M, M, are rods serving
to connect bar K with a beam N on the other side of rail 321 in such manner that
by moving beam away from rail 321, bars J and K will be drawn towards the
same, springs 0 around bolts M serving to force said bars back into their original
positions when the thrust on beam N ceases. Said beam N may be actuated by
hand, treadle mechanism, or in any other suitable manner, and in addition to
springs O any suitable positive locking mechanism may be used for holding bars J
and K in their normal positions. Said bars are employed to actuate levers 58
and 581, said levers being so shaped and so provided with suitable projections
directly opposite bars J and K that such engagement will be had with said bars
upon shifting the same laterally that when these bars are shifted as far as
practicable towards rail 32' into positions J, K, the feet of said levers will be
forced thereby into the positions A and B shown in dotted lines in Fig. 5, which
correspond with the positions of the two spreaders in Fig. 6, and that when said bars
are returned to their original positions either by the action of springs O, or
by any other suitable means, the spreaders will be forced either into the positions
shown in Fig. 7, or into those shown in Fig. 8, according to the position of the
carriage beyond one or the other end of the drum, where such shifting must
always be accomplished. Referring first to lever 58, when the carriage is at the
right hand end of the drum, its lower end will then occupy either a position as A¹
or A2, or an intermediate position laterally, and the movement of bar J
towards rail 321 will wherever the end of said lever may be at the time cause the
bar to so co-act with portion W of lever 58 as to carry its end. A into the corre-
sponding position A³. The same will occur if the carriage be located at the left.
hand end of the drum. If the carriage be. at the right hand end of the drum
upon finishing the first of a series of streaks the foot of lever 58 must be brought
from A into a position as A2 when the second streak is to be printed, so as to

page_text: place the spreader 47 in the position shown in Fig. 7. For such purpose the
spur P is provided near the lower end of lever 58, said spur being of such length
that when the foot A of said lever is at A2 said spur will contact with bar K and
therefore movement of said bar into its normal position will force foot A from A
into position A² At the left hand end of the drum, foot A will likewise be
forced into a position as A3 (which is in the same alignment with A²), and from
there shifting block D which, as stated before, moves with bar K and which had
previously been located in position 15 shown in dotted lines, will conduct said
foot along one of its guiding surfaces or into its proper position A* corre-
sponding with the position of scraper 47 in Fig. 8.
Lever 58 is actuated in similar manner when its foot B passes into and out
of the positions B. Its spur Q is of such length that when bar J is shifted
to J said bar and said spur will be in contact and said foot will occupy position B
while the return of bar K to its normal position will so bring it in contact with
said lever 58 that it will be brought in a position in the alignment B3, B', and if
at the right hand end of the drum, moveable shifting block E which has previously
been occupying the position E will then force foot B into its proper position B³.
The top of shifting block D is lower than the bottom of B, so as to avoid conflict
between these parts.
I prefer to make the front and rear faces X and Y of that portion of arm 44
which telescopes with the lower hollow portion of spreader 47 convex allowing
there enough play between these telescoping parts, to permit the spreader to
tilt or rock forward and rearward sufficiently to accommodate itself properly to
the portions of the drum to which it is applied. To the sides Z of the spreader
I prefer to give a sufficient gradual slope to guard against cutting of the yarn by
the longitudinal edges of the rubbing surface in case accidentally lateral dis-
placement of the spreader should be brought about while the same is in contact
with the yarn.
In the construction illustrated in Fig. 9, post 43* is shown to be extended
downward sufficiently to bring its foot A opposite a proper shifting block C* to
be actuated directly by enforced contact with its deflecting surfaces. In view
of the explanation given above as to the rules governing proper arrangement of
shifting blocks and of bars J and K it is not deemed necessary here to set forth how
such arrangements should be made with reference to this particular case.
While the direct contact of the foot A* of post 43 with shifting block C* some-
what simplifies the construction certain advantages are sacrificed thereby which
the use of levers as 58 offers. Thus, by changing the fulcrumage of such levers
greater or less lateral displacement of posts 43, 431 and of the spreaders
can be obtained while using the same shifting blocks, providing such
posts be furnished with a sufficient number of vertical notches, as
shown in Fig. 14; this is particularly desirable when say color wheels of half or
double widths and in combination therewith spreaders of half or of double widths
are to be used. Besides, when employing levers as 58 a considerable lateral travel
of the foot A of such lever can be made to produce comparatively small lateral dis-
placement of the spreader and thereby more perfect adjustment of its movements
can be secured. When the fulcrumage of lever 58 is to be changed as referred to
above pin 59 must be withdrawn from holes h and and must be inserted instead
in other suitable holes, as h* and *.
Operators in seeking to expedite the work are apt to throw or partly revolve
the drum too quickly and before the color wheel and the spreaders have entirely
passed from underneath it and particularly from contact with the yarn. This
tends to cause derangement of the apparatus and of the yarn and irregularities in
the work and especially in the alignment of the streaks near the end of the drum.
To guard against this I employ the following appliances: 62 is an interior gear-
ing at that end of the drum where the printer stands while operating the machine.
63 is a hand wheel on shaft 64 operating a pinion 65 in mesh with the gear wheel
for the purpose of properly revolving the drum after the printing of each streak

page_text: 66 is an additional toothed wheel having the same number of teeth as pinion 65,
and 67 a lever fulcrumed on shaft 68, which shaft may be mounted upon any
suitable part of the drum supporting frame. This lever, actuated by its own
weight, and by a spring 69 if desired, is normally held at its upper end in lock-
ing contact with toothed wheel 66 thereby preventing the turning of hand wheel 63
and of revolving of drum 33. 70 is a projection on the axle of wheels 10 or
on any suitable portion of the carriage body, so placed as to come in contact with
the lower end of lever 67 as soon as spreader 471 has emerged from underneath
the drum and to swing said lever out of engagement with toothed wheel 66 and
to thus permit revolving of the drum. Just after the carriage and spreader 47
have passed from underneath the left hand end of the drum a projection 71 on
the right hand portion of the carriage will strike a lever 72 so placed and fulcrumed
at 73 as to throw .lever 67, through the instrumentality of a connecting rod 74,
out of its locking engagement and re-locking will be prevented until the carriage
starts upon its return trip when lever 72 is permitted to reassume its vertical
position: By so adjusting the positions of levers 67 and 72 and of the appliances
for shifting levers 58 and 58 that lever 72 as well as the shifting devices will
be actuated substantially simultaneously immediately after the spreader behind
the color wheel emerges from underneath the drum, as shown in the drawings,
the promptest possible operation of the apparatus is made possible.
In Figures 10 and 11, I have shown rockers 75 and 751 mounted in front and in
the rear of color wheel 23. Armstand t¹ being held in their operative positions
simultaneously when the wheel 23 is travelling towards the right and arms u
and u being so held in contact with the yarn while said wheel is travelling towards
the left, the alternate tuting of the rockers, (as well as of hinged levers as shown in
Figs. 12 & 13), being produced by any suitable tilting mechanism, arms of the two
rockers 75 and 75 for such purpose being either joined together by a connecting
rod or operated independent of each other. The operative faces of said arms may
be made as shown in full or in dotted lines in Fig. 10, or of any other suitable
widths and alignments, so as to produce proper rubbing and re-rubbing of the
yarn thereby. When a single streak is to be rubbed all the arms should be held
out of contact with the yarn, for instance by lowering in known manner the
standards carrying bearings of axles v, vl, unless some of the spreaders be made to
cover only the streak in course of application, when such spreaders might be
maintained in contact with the yarn at all times.
In Figs. 12 and 13, I show hinged spreaders 76 and 761 held in contact with
the yarn simultaneously on one side of the color wheel while travelling towards the
right and hinged spreaders 77 and 77 adapted to be held against the yarn when
travelling towards the left in positions either as indicated in Fig. 12, or in any
other suitable positions.
It will readily be seen that many features referred to above might be varied
without departing from the spirit of my invention. Thus, the support for a spreader
might be shifted, laterally or otherwise so as to alternately assume and to be locked
in positions to the right and to the left of the color wheel, while the same is
travelling towards the left and then towards the right, corresponding with alternat-
ing operative positions of the spreader on opposite sides of said wheel.
Any suitable form of spreaders and any suitable number and arrangement of
supporting springs may be used in place of those illustrated.
In the business of printing carpet yarns a very great number of different shades
and colors are employed and it is a peculiarity of some of the coloring substances
so used that they will more readily and thoroughly enter into and spread through
the yarn if rubbing action is applied thereto substantially simultaneously with
the printing operation, while in regard to others a short interval between the
printing and the rubbing operation, such as is afforded between the printing of
different streaks secures the best results.
...
By rubbing one portion of a streak substantially simultaneously with the print-
ing operation while imparting the first rubbing to another portion of said streak

page_text: during a subsequent printing operation as explained above, good results may be
accomplished with the aid of the subsequent steaming and scouring process in
either case.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
. 1. In the art of printing and coloring yarns, the method herein described of
successively applying streaks of color to yarn and partially equalizing the same,
which consists in printing such a streak, subjecting during its printing a portion
only of its width to rubbing action, then printing another streak and during the
printing of the same subjecting a portion of the width of said successive streak
and rubbed and unrubbed portions of the previous streak to rubbing actions.
2. In the art of printing and coloring yarns, the method herein described of
successively applying streaks of color to the yarm and partially equalizing
the same, which consists in printing such a streak, subjecting during its printing
a portion only of its width to rubbing action, then printing an adjoining streak and
during the printing of the same, subjecting a portion of the said successive streak
to rubbing action and simultaneously subjecting a portion of the former streak
left unrubbed during the printing of the same to two independent rubbing actions
and also subjecting a portion of said former streak previously rubbed to an addi-
tional rubbing action.
3. In apparatus for printing yarns, the combination with the yarn drum, the
color carriage and the distributing wheel, of a support carrying a suitable rubbing
surface, mechanism for shifting said support, and means independent of the color
carriage adapted to lock said support in varying positions corresponding with
varying operative positions of the rubbing surface.
4. In apparatus for printing yarns, the combination with the yarn drum and the
distributing wheel, of a spreader secured in proper relation with the color wheel,
and means for moving said spreader laterally, with reference to the path of the
color wheel.
5. In apparatus for printing yarns, the combination with the yarn drum and
the distributing wheel, of spreading means, and mechanism for alternately produc-
ing rubbing contact between portions of such spreading means and the yarn on
the drum in different positions, laterally, relative to the path of the color wheel.
6. In apparatus for printing yarns, the combination with the yarn drum and
the distributing wheel of a spreader capable of lateral movement, a shifting block
having a lateral deflecting surface, a shoe adapted to travel along the same and
means for imparting movement from said shoe to said spreader.
7. In apparatus for printing yarns, the combination with the yarn drum and
the distributing wheel, of a spreader capable of lateral movement, a shifting block
having a proper deflecting surface, a shoe adapted to travel along the same,
means for imparting movement from said shoe to said spreader, and mechanisin for
shifting said spreader independent of said shifting block.
8. In apparatus for printing yarns, the combination with the yarn drum and
the distributing wheel of mechanism adapted to apply rubbing means to a single
streak only, or to two streaks simultaneously.
