Improvements in Yarn Printing Apparatus.
I, PHILIP ARTHUR NEWTON, of the Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in yarn printing apparatus of that class
in which the printing mechanism proper, consisting of a color-box containing
coloring material and a distributing wheel rotating therein, is removably mounted
in a carriage adapted to reciprocate from end to end of a drum carrying the yarn,
and which carriage is provided with rubbing appliances, movable automatically
into and out of operative position alternately at opposite ends of the movement
of the carriage, for engaging the yarn, and removing therefrom ridges formed
between two or more adjoining stripes of the same color applied thereto by the
wheel.
The present invention relates more particularly to such rubbing appliances,
and to means for automatically moving them into and out of operative position
at the ends of the movement of the carriage in opposite directions, and also to
means for retaining them, during movement of the carriage in printing, in the
positions to which they are thus moved.
The frame of the machine is provided with rails for supporting a wheeled
carriage provided with cables passing over pulleys connecting with a suitable
source of power for moving the carriage back and forth beneath the yarn drum
in the usual way. Hinged in the carriage is a plate provided with an opening
which registers with a similar opening beneath it in the carriage for receiving
the removable color-box containing the coloring material. On opposite sides
of the opening, the plate is also provided with journals for receiving the shaft
of a distributing wheel immersed in the coloring material in the color box, and
which, during the movement of the carriage, engaging the yarn upon the drum,
applies stripes of color thereto in the usual way. The plate may also be provided
with the usual devices for turning the distributing wheel in the color box as the
carriage moves under the drum, so as to ensure thereon a constant supply of
coloring material. The contact of the distributing wheel with the yarn drum
is rendered yielding by the provision of a spring secured to the carriage, and
engaging the under side of the plate; the upward movement of the plate, color
box, and distributing wheel, by the spring, being limited by a nut on the upper
end of a bolt secured to the carriage, and projecting through an opening in the
free end of the plate.

page_text: On opposite sides of the distributing wheel, the carriage is provided with a pair
of rubbing appliances or rubbers, each 'mounted in a rearwardly inclined support,
and provided with a rubbing surface which, in the operative position of the
rubber, is adapted to assume an upwardly and rearwardly inclined position rela-
tively to the drum, with its rear edge bearing against the latter, so as to contact
with the yarn upon the drum, with a pressure progressively increasing rear-
wardly.
With a rubber so constructed and contacting with the yarn in this manner,
a more perfect rubbing and spreading action is obtained (and without removal
of the coloring matter from the yarn), than is possible with scraping or rubbing
appliances such as heretofore devised. These rubbing appliances are each con-
structed of a block of semi-yielding material, preferably-hard vulcanized rubber,
which is rearwardly bevelled at its upper end, to provide an inclined rubbing
surface terminating in a sharp bearing rear edge. With such a yielding, rear
vedge, and an inclined. contacting surface leading up to it, a rolling, action on
each thread is obtained, resulting in a still more thorough distribution or equali-
zation of color. Another advantage in employing such yielding rear, edge.is, that
it avoids all liability of lateral displacement of the yarn threads by the rubber,
as its rear-edge yields sufficiently, as it engages each, thread,, to pass it without
moving it forward.
1
The connection between each rubber and its support also is preferably such as
to permit adjustment of the rubber longitudinally, such connection, in the
present case, consisting of a wedge-shaped block engaging a corresponding opening
in the rear side of the rubber, and provided with a screw or screws passing through
the support, by which the block is held in locking position. To adjust the rubber,
all that is necessary to be done is to loosen the screws, and move the rubber to
the desired position; or it may be removed entirely for repairs, or to be replaced
by another.
The rubbing appliances are adapted to be moved automatically into and out of
position, to alternately engage the drum, by mechanism which will now be
described. Each of the supports of the 'rubbing appliances is loosely journalled
on a shaft secured between brackets rising from the body of the carriage, and is
provided with a spring engaging a link also journalled loosely on said shaft, and
through which spring, as the link is swung outwardly, the rubber is moved into,
and held yieldingly in, operative position. Movement to inoperative position of
an elevated rubber is effected by a projection on the link, which, as said link is
swung inwardly, engages a projection on the rubber support, and swings, the
latter with its rubber downwardly. This movement of the rubber may be assisted
by a spring, connected to the link and to the carriage, which will also assist in
retaining the rubber in inoperative position. The link of each rubber is also
provided with a slot receiving a pin carried by an arm secured to a rock shaft
journalled between the brackets supporting the rubber. This rock shaft is
provided with a second arm connected by a link to a lever pivotted to the carriage
in a bracket. Each of these latter levers has pivotted to it, a depending rod,
provided, at its lower. end, with a bowl adapted to be engaged by, tripping
mechanism, at opposite ends of the movement of the carriage, which tripping
mechanism, by depressing and elevating said rod, effects the movement of the
rubber into and out of rubbing position respectively. The depending rods for
the two rubbers, and the connections between them, and. their respective rubbers,
are located on opposite sides of the carriage.
It will be understood that, as one of the depending rods is depressed, it will
rock the lever from which it depends, and, through the link and rock shaft
connected to said lever, move the pin carried by the arm connected to said rock
shaft downwardly in the slot of the link, thereby moving the latter outwardly,
and, through the spring interposed between it and its rubber, swing the latter
upwardly into operative position, in which position it will be retained by said

page_text: pin, which, in moving, the link outwardly, moves past a central position, and
becomes locked in that position. It will be understood, also, that as the depending
rod is raised, the pin moved thereby will, through the connections described, be
moved, upwardly in the slot of the link, thus drawing the link inwardly, and
through the connections described, and with the assistance of a spring connected
to the link and the carriage, move the elevated rubber to inoperative 'position.
The tripping mechanism for engaging the depending rods, to move the respective
rubbers into and out of operative position,, consists of two sets of camis, one set,
for depressing the rods and raising the rubbers into operative position, and the
other.set for elevating the rods, and lowering the rubbers out of operative position.
The depressing cams are located at opposite ends of the path of movement of
the carriage, and secured one to each of the rails, while the elevating cams are
arranged in line therewith, and also secured to said rails. From this arrange-
ment of cams it follows, that as the carriage reaches the end of its movement in
one direction, with one of its rubbers elevated and the other depressed, the bowl
of the depending rod of the elevated rubber will be engaged by the elevating
cams at that end of the machine, and said rod elevated, thereby rocking its lever,
and, through the connections described, withdrawing the elevated rubber from
operative position. Simultaneously, the depressing cam at the same end of the
machine, will engage the bowl of the depending rod of the then inoperative
rubber,, and depress said rod, and, through the connections described, raise said
rubber to cpérative position, and lock it in that position, ready for the return
movement of the carriage. At the end of the movement of the carriage in the
opposite direction, the elevating cam at that end will engage the bowl of the
depending rod corresponding to the operative rubber, and release said rubber,
which is then returned to inoperative position, while the depressing cam at the
same end of the machine, engaging the bowl of the depending rod of the then
inoperative rubber, will depress the said rod, and thus again render said rubber
operative.
During the movement of the carriage, it will be understood that the elevated
rubber following it, yieldingly supported by its spring, as it reaches the drum,
will be slightly depressed thereby, and that, as it passes under the drum, its
rubbing surface will maintain an upwardly and rearwardly inclined position
relatively thereto, in contact with the yarn, the rubber being free to yield
bodily, and also adapted to yield at its rear bearing edge independently of its body.
As is well understood, rubbing devices such as described are used only on the
application to the yarn, of the second or third of a series of adjoining stripes of
the same color, and it is essential that, during the application of the first stripe
of a series, and during the application of isolated stripes to the yarn, both rubbers
should be maintained out of operative position, as in such case, if a rubber
should contact with the yarn, the color of one stripe would be forced thereby into
the adjoining and differently colored stripe, thus blurring the pattern. For this
reason, the cams, which throw the rubbers into operative position, are made
ádjustable into and out of position for engagement with the depending rods, each
of said cams being hinged to the frame of the machine, and connected by a link
to an arm secured to a rock shaft mounted in suitable standards, and provided
with an arm connected by a link to one end of a bell-crank lever pivotted in a
standard, and the opposite end of which is provided with a pin entering a slot
in a treadle pivotted in a standard at one side of the machine. On depressing
the treadle, the pair of depressing cams (those which move the rubbers to operative
position) will be moved from operative position into inoperative position, and,
when so moved, will permit the bowls of the depending rods to pass without
engagement. The bowl, corresponding to the rubber which is operative, will then
be engaged by one of the elevating cams, and that rubber rendered inoperative.
On the release of, the treadle (which remains depressed until the printing of
successive adjoining stripes of the same color is resumed, and the first or second

page_text: stripe of the series has been printed), the 'depressing cams will be restored
automatically to operative position by a spring secured to the rock shaft to
which said cams are connected, and to a stationary part of the machine.
If desired, the rubbers may be made sufficiently wide to embrace the ridges
formed between three adjoining stripes. In such case, the rubbers would be
retained out of operative position until the formation of the third stripe of a
series, and would of course not be used where only two adjoining stripes were
applied to the yarn.
Dated this 19th day of August 1897.
I, PHILIP ARTHUR NEWTON, of the Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention relates to improvements in yarn-printing apparatus of that class
in which the printing mechanism proper, consisting of a color box containing
coloring material, and a distributing wheel rotating therein, is removably mounted
in a carriage adapted to reciprocate from end to end of a drum carrying the yarn,
and which carriage is provided with rubbing appliances movable automatically
into and out of operative position alternately at opposite ends of the movement
of the carriage for engaging the yarn, and removing therefrom ridges formed
between two or more adjoining stripes of the same color applied thereto by the
wheel.
The present invention relates more particularly to such rubbing appliances,
and to means for automatically moving them into and out of operative position
at the ends of the movement of the carriage in opposite directions, and also to
means for retaining them, during movement of the carriage in printing, in the
positions to which they are thus moved.
In the accompanying drawings, Figure 1 is a side elevation of a yarn printing
apparatus embodying the present invention. Fig. 2 is a plan view of the same.
Fig. 3 is a side elevation, on a slightly enlarged scale, illustrating both of the
rubbing appliances in inoperative positions. Fig. 4 is a section on the line 4 of
Fig. 1. Fig. 5 is a section on the line 5 of Fig. 1, and omitting the travelling
carriage. Figs. 6 and 7 are details, on an enlarged scale, of one of the scrapers,
Fig. 7 being a section on the line 7 of Fig. 6. Fig. S is a sectional elevation of
one of the rubbing appliances and a portion of the drum, illustrating the rubbing
appliances in engagement with the drum; and Fig. 9 is a section on the line 9
of Fig. 8.
Referring to said drawings, the frame of the machine therein shown is provided
with rails 2, 3, for supporting a wheeled carriage 4, provided with cables 5, 6,
passing over pulleys 7, 8, connecting with a suitable source of power, for moving
the carriage back and forth beneath the yarn-drum in the usual way. Hinged
at 10 in the carriage 4 is a plate 11, provided with an opening 12, which registers
with a similar opening beneath it in the carriage 4, for receiving the removable
color-box 13, containing the coloring material. On opposite sides of the opening 12,

page_text: the plate 11 is also provided with journals 14, 15, for receiving the shaft 16 of a
distributing-wheel 17, immersed in the coloring material in the color-box 13,
and which, during the movement of the carriage, engaging the yarn upon the
drum 9, applies stripes of color thereto in the usual way. The plate will also be
provided with the usual devices (not shown) for turning the distributing-wheel 17
in the color-box as the carriage moves under the drum, so as to ensure thereon
a constant supply of coloring material. The contact of the distributing-wheel 17
with the yarn-drum 9 is rendered yielding by the provision of a spring 18, secured
to the carriage, and engaging the under side of the plate 11, upward movement
of the plate, color-box, and distributing-wheel by the spring 18 being limited
by a nut 19 on the upper end of a bolt 20, secured to the carriage 4, and projecting
through an opening in the free end of plate 11.
On opposite sides of the distributing-wheel 17, the carriage 4 is provided with
a pair of rubbing appliances 21, 22, each mounted in a rearwardly-inclined
support 57, and provided with a rubbing-surface 21", 22", respectively, which,
in the operative position of the rubber, is adapted to assume an upwardly and
rearwardly inclined position relatively to the drum, as shown in Fig. 8, so as to
contact with the yarn upon the drum with a pressure progressively increasing
rearwardly. With a rubber so constructed and contacting with the yarn in this
manner, a more perfect rubbing and spreading action is obtained (and without
removal of the coloring-matter from the yarn) than is possible with scraping or
rubbing appliances such as heretofore devised. These rubbing appliances 21, 22,
are preferably also each constructed, as shown, of a block of semi-yielding material,
such as hard vulcanized rubber, which is rearwardly beveled at its upper end,
to provide an inclined rubbing-surface, terminating in a sharp bearing rear edge,
although other material may be used for the block, and the latter formed without
the sharp bearing rear edge. The connection between each rubber and its
support 57 also is preferably such as to permit adjustment of the rubber longi-
tudinally, such connection in the present case consisting of a wedge-shaped
block 58, engaging a corresponding opening in the rear side of the rubber, and
provided with a screw or screws 59 passing through the support 57, by which the
block 58 is held in locking position. To adjust the rubber, all that is necessary
to be done is to loosen the screws 59, and move the rubber to the desired position,
or, it may be removed entirely for repairs, or to be replaced by another.
The rubbing appliances 21, 22, are adapted to be moved automatically into
and out of position to alternately engage the drum by mechanism which will now
be described. Each of the supports 57 of the rubbing appliances is loosely jour-
naled on a shaft 23, secured between brackets 24, rising from the body of the
carriage 4, and is provided with a spring 60, engaging a link 27, also journaled
loosely on the shaft 23, and through which spring, as the link 27 is swung
outwardly, the rubber is moved into, and held yieldingly in, operative position.
Movement to inoperative position of an elevated rubber is effected by a pro-
jection 25 on the link 27, which, as said link is swung inwardly, engages a
projection 26 on the support 57 (see Figs. 6 and 7), and swings the latter, with
its rubber, downwardly. This movement of the rubber may be assisted by a
spring, as 29, connected to the link 27 and to the carriage 4, which will also
assist in retaining the rubber in inoperative position. The link 27 is provided
with a slot 28, receiving a pin 29, carried by an arm 30, secured to a rock shaft 31,
journaled between brackets 24. The rock-shaft 31 is provided with a second
arm 32, connected by a link 33 to a lever pivoted to the carriage 4 in a bracket 34,
such lever, corresponding to rubber 21, being for convenience numbered 35, while
the lever corresponding to rubber 22 is numbered 36. Each of these levers 35, 36,
has pivoted to it a rod 37, 38, respectively, provided at its lower end with a
bowl 39, 40, respectively, adapted to be engaged by tripping mechanism at
5. opposite ends of the movement of the carriage, so as to effect the movement of
the rubber into and out of rubbing position. The rods 37, 38, for the two

page_text: rubbers 21, 22, and the connections between them and their respective rubbers,
are, as will be observed, located on opposite sides of the carriage.
From the foregoing it will be understood that as the rod 37 or 38 is depressed,
it will rock its lever 35, and, through the link 33, rock the shaft 31, and move
the pin 29 downwardly in the slot 28, thereby moving the link 27 outwardly,
and, through the spring 60, swinging the rubber 21 or.22 upwardly into operative
position, in which position it is retained by the pin 29, which, as will be observed,
in moving the link 27 outwardly, moves past the rock-shaft 31, and becomes
locked in that position. It will be understood, also, that as, the rod 37 or 38
is raised, the pin 29 will, through the connections described, be moved upwardly
in the slot 28, thus drawing the link 27 inwardly, and, through the projec-
tions 25, 26, and with the assistance of spring 29ª, moving the elevated rubber
to inoperative position.
The tripping mechanism for engaging the rods 37, 38, to move the respective
rubbers 21, 22, into and out of operative position, consists of two sets of cams,
one set, 41, 42, for depressing the rods 37, 38, respectively, and moving the
rubbers 21, 22, respectively, into operative position, and the other set, 43, 44,
for raising the rods 37, 38, respectively, and moving the rubbers 21, 22, respec-
tively, out of operative position. The cams 41, 42, are located at opposite ends
of the path of movement of the carriage, and secured to rails 2, 3, respectively,
while cams 43, 44, are arranged in line therewith, and secured to the rails 3. 2,
respectively. From this arrangement of cams, it follows that as the carriage
reaches the end of its movement, towards the right, for example, Figs. 1 and 2,
with its rubber 21 elevated, and rubber 22 depressed, the bowl 39 of rod 37 will
be engaged by cam 44 at the end of the machine, and said rod elevated, thereby
rocking the lever 35, and moving the pin 29 from locking position inwardly in
the slot 28. As the pin 29 is thus moved, it will, aided by the spring 29, move
the link 27 inwardly, and thus withdraw the rubber 21 from operative position.
Simultaneously, the cam 42, at the same end of the machine, will engage the
bowl 40 of rod 38, and depress said rod, and, through the connections described,
rock the shaft 23 of rubber 22, which is then in inoperative position, and move
the pin 29 downwardly in the slot of link 27, corresponding to said rubber, which
is thus, through its spring 60, swung into operative position, and locked in that
position by pin 29, ready for the return movement of the carriage. At the end
of the movement of the carriage in the opposite direction, the cam 43 will engage
the bowl 40, and depress rod 38 and release the rubber 22, which is then returned
to inoperative position, while cam 41, engaging bowl 39 of rod 37, will depress
the latter, and thus again render the rubber 21 operative.
During the movement of the carriage it will be understood that the elevated
rubber following it, yieldingly supported by its spring 60, as it reaches the drum,
will be slightly depressed thereby, and that, as it passes under the drum, its
rubbing-surface will maintain an upwardly and rearwardly inclined position
relatively thereto in contact with the yarn, the rubber being free to yield bodily,
and also adapted to yield at its rear bearing edge independently of its body.
As is well known, rubbing devices in yarn printing machines are not used on
the application to the yarn of certain stripes,-as, for instance, a single isolated
stripe of a color, or the first, or, in some cases, the last stripe, of a series of
adjoining stripes of the same color, the stripes upon which the rubbers are used
depending somewhat upon the width of the rubbers employed, and their position
relatively to the distributing-wheel, and it is desirable that during the application
of the first, and, in some cases, the last stripe, of a series, and during the appli-
cation of isolated stripes to the yarn, both rubbers should be maintained out of
operative position, as in such case, if a rubber should contact with the yarn, the
color of one stripe would be forced thereby into the adjoining and differently-
colored stripe, thus blurring the pattern. For this reason, the cams 41, 42,
which throw the rubbers 21, 22, into operative position, are made adjustable into

page_text: and out of position for engagement with the levers 37, 38, each of the said
cams 41, 42, being hinged to the frame of the machine, and connected by a link 45
to an arm 46, secured to a rock-shaft 47, mounted in suitable standards 48, and
provided with an arm 49, connected with a link 50 to one end of a bell-crank
lever 51, pivoted in a standard 52, and the opposite end of which is provided
with a pin 53, entering a slot in a treadle 54, pivoted in a standard 55. One
depressing the treadle 54, the cams 41, 42, will be moved from operative position
into inoperative position, as shown in Figs. 3 and 4, and, when so moved, will
permit the bowls 39, 40, to pass without engagement. The bowl 39 or 40 of the
rubber which is operative will then be engaged by the cam 43 and 44, as the case
may be, and that rubber rendered inoperative. On the release of the treadle 54,
which remains depressed until the printing of successive adjoining stripes of
the same color is resumed, and the first stripe or stripes of said series upon which
the rubbers are not to be used have been printed, the cams 41, 42, will be
restored automatically to operative position by a spring 56, secured to the rock-
shaft 47, and to a stationary part of the machine.
The present invention may be used with rubbers of any suitable width and
position relatively to the distributing-wheel, the width and position of the rubbers
forming no part of this invention, but they are shown as wider than the dis-
tributing-wheel, and mounted directly in line therewith.
It is not intended to claim herein the combination, with the drum, carriage,
and distributing-wheel, of alternately-operating rubbing appliances on opposite
sides of the wheel, with tripping devices for effecting the movement of the rubbing
appliances to operative position, and to a position in which both are inoperative,
and adjustable into and out of the position in which they effect the movement
of the rubbing appliances, to operative position, nor the same feature, with
separate tripping devices, for effecting the movement of the rubbing appliances
to operative position, and to a position in which both are inoperative, nor with
means carried by the carriage for locking the rubbing appliances thereto and
retaining them in operative position, as these subjects-matter are included in
another Application, No. 19206, dated August 19th 1897, these combinations being
