IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF LOOPED FABRICS
Year: 1871

page_text: LETTERS PATENT to John William Lamb, Manufacturer, and Samuel
Lowe, Machinist, both of Nottingham, in the County of Notting-
ham, for the Invention of 'IMPROVEMENTS IN MACHINERY FOR THE
MANUFACTURE OF LOOPED FABRICS."
Sealed the 9th February 1872, and dated the 14th November 1871.
PROVISIONAL SPECIFICATION left by the said John William Lamb
and Samuel Lowe at the Office of the Commissioners of Patents,
with their Petition, on the 14th November 1871.
We, JOHN WILLIAM LAMB, Manufacturer, and SAMUEL LOWE,
Machinist, both of Nottingham, in the County of Nottingham, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR THE MANUFACTURE OF LOOPED FABRICS," to be as follows:―
The object of this Invention is to enlarge the capabilities of the
machine for manufacturing looped fabrics, patented by William Cotton
on the 16th December 1804, No. 3123. In this construction of
A

page_text: machine two independent thread carries are used for making hose,
which carriers are severally mounted on a traversing guide rod, which
rods are actuated to a determinate amount by means of a slur box
to which they are attached by friction of contact only. The traverse
motion of the rods is arrested by stops which are caused to limit the
range of motion of the thread carriers to suit the progress of the work
in hand and thereby to enable the carriers to lay their threads
under the beards of a determinate number of needles. These thread
carriers being so arranged as to move in the same plane they cannot
cross each other's paths, and for this reason the capacity of the machine
is limited.
Now the objects of the present Invention are to enable the machine
to knit hose and other articles in lines or bands of alternate colours, and
also to knit the upper part of the foot of the hose while the heel is
being formed, instead of resorting to another machine for effecting that
object after the heel has been formed. It is also proposed to improve
the operation of splicing the fabric at the parts requiring an extra
thickness, as for example, the seat of pants and in the hose before
coming to the heel. These objects are attained by the use of an
additional guide bar and thread carrier or carriers. This guide bar
receives, like the guide rods, an endway motion from the traverse of
the slur box to which it is attached by friction of contact.
The amount of its traverse is also regulated, like the rods of the
other thread carriers, by adjustable stops. All the thread carriers are
capable of being thrown out of action when desired by means of drop
levers whose movements are regulated by a self-acting wheel or cam
operating on those levers. The thread carrier or carriers on the
additional guide bar are so arranged with respect to the other thread
carriers as to overlie and be able to move freely past them and to deposit
their threads on any desired portion or portions of the line of needles.
It is also necessary for the purposes of this Invention to enable the
additional thread carrier to act at times alone, and for this purpose the
back thread carriers are held fast out of action.
When manufacturing hose with lines or bands of different colours
alternated, the front or additional thread carrier will take, say, a red
thread, and one of the back carriers, say, a brown thread. These two
carriers will be thrown alternately into and out of action, say at the end
of two or four " courses," by means of the aforesaid self-acting wheel or

page_text: cam, and this system of working will be continued until the heel is
reached. Supposing a continued alternation of colours not to be
required beyond this point all the thread carriers will now be brought
into action; the front or the additional carrier will then be limited in its
traverse to the width of the foot piece, and the other two carriers
(having threads of the like colour) will be limited in their traverse to
one half the width of the heel. These three carriers will be operated so
as to produce independent work side by side. When the heel has been
.completed the action of the back carriers which laid the threads for the
heel will be arrested and the front carrier only will continue to be
actuated, to complete the formation of the foot piece. When the toe
portion is reached the narrowing will be commenced and continued in
the ordinary manner until the toe is completed.
For plaiting the front carrier or carriers will be used in conjunction
with one or both of the back carriers, the object being for two carriers
to supply thread to the same needles for each "course." In order to
make better plaiting than this machine has been hitherto able to effect,
one of these thread carriers, say the front or additional one, is caused to
move in advance of the back carrier both at its forward and back
traverse. This is effected by delaying the start of the back carrier
by means of an automatic stop worked by the traversing slur box.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John William Lamb and Samuel Lowe in the
Great Seal Patent Office on the 14th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WILLIAM LAMB, Manufacturer, and SAMUEL LOWE, Machinist, both of
Nottingham, in the County of Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-one, in
the thirty-fifth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said John William Lamb

page_text: Now the objects of the present Invention are, first, to enable the
machine to knit hose and other fabrics in lines or bands of alternate
colours.
Secondly. To knit the instep of the hose while the heel is being
formed, instead of (as is now the case) having to resort to another
machine for effecting that object after the heel has been formed.
Thirdly. To improve the operation of splicing the fabric at the parts
requiring an extra thickness, as for example, the seat of pants and the
heel of hose or for "plating" the whole surface.
These objects are attained by the use of additional thread carriers.
The additional thread carriers are fitted to a guide bar or guide bars,
which like the guide rods will receive an endway motion from the
traverse of the slur box to which such guide bar or bars is or are
attached by friction of contact. The amount of traverse of the guide
bars is also regulated like the rods of the other thread carriers by
adjustable stops. The thread carriers are capable of being thrown out
of action, when desired, by means of drop levers whose movements are
regulated by a self-acting wheel or cam operating on those levers. The
thread carrier or carriers on the additional guide bar are so arranged
with respect to the other thread carriers as to overlie and be able to
move freely past them, and to deposit their threads on any desired
portion or portions of the line of needles. It is also necessary for the
purposes of this Invention to enable the additional thread carriers to
act at times alone, and for this purpose the back thread carriers are held
fast out of action.
We will first describe our Invention as applied to the manufacture of
striped work, hose or half hose being the articles adopted to illustrate
our improvements.

page_text: is shewn detached at Figures 3 and 4; in the latter of these Figures it
will be seen that the bar is fitted with a strap piece o to which the
friction driver D is secured. This friction driver D is connected, as
shewn at Fig. 1, Sheet II., by a bracket arm D¹ to the slur box E. It
will be understood that there is a slur box E for each division of the E
machine, but as these boxes are all connected together by the longi-
tudinal bars E*, E*, which serve also to secure the boxes to the slur

bar E¹ they will all have one uniform motion.
with guides to receive the rods A, B, of the thread carriers 1 and 2,
and they carry friction drivers for operating the needle carriers. The 1
limit of motion of the thread guides is determined by adjustable
stops F, F¹, Fig. 1, Sheet I., which are worked automatically as usual
when the "fashioning" is proceeding.
It will be unnecessary to describe in detail the action of this well-known
machine; but in order to render clear the application of our improve-
ments thereto we have shewn at Fig. 2, Sheet II., a cross section of the
machine in which the relative positions of the working parts will be
clearly seen. a shews the position of the ordinary thread carriers, b
shews the additional thread carrier for throwing an additional thread
under the beard of the needles c. This thread carrier is substantially of
the same construction as those used in the "cotton machine," as will be
seen by reference to the front view, Fig. 1*, Sheet II. Referring again
to Fig. 2, d is the jack sinker worked by the jack e, and by which the
requisite amount of slack thread is taken up; fis an incline on the under
side of the slur box for pressing forward the jacks and thereby thrusting
the jack sinkers into the dotted position; g is a vibrating bar for
retracting the sinkers, and h is the knocking off comb for pressing the
formed loops over the beards of the needles (as they descend) and thereby
completing a course of knitting.
In order to produce striped work with the improved machine as shewn
.at Fig. 1, Sheet I., the thread carriers 1 are thrown out of action. This is
effected by uncovering an opening in the stop F in a line with the rod A,
and by drawing the rod through this opening until a notch with
which the rod is provided is brought opposite the catch of a stop G,
then by raising this catch the rod will be held fast as shewn in the
sectional diagram Fig. 5. While the rod A is locked its friction driver
operated by the traverse of the slur box will simply slide over the rod
and leave the thread carriers 1 quiescent. This motion of the slur box

page_text: will serve however to operate the other thread carriers 2 and 3, which
while striped work is being made must be worked alternately. To
ensure this an automatic arrangement is provided for throwing these
thread carriers alternately into and out of action.
-
This arrangement is shewn in several views in Sheet III., where Fig. 1
is an end elevation; Fig. 2 is a plan view of the same; Fig. 3, front
elevation; and Fig. 4 a back elevation of the apparatus. It consists of a
catch lever H pivotted to a bracket H³, carried by the slide of the stop
F¹ (Fig. 1, Sheet I.). This lever H is provided with an arm H that rides
on the periphery of a pattern cam I, and it is further fitted with two
catches h and h³, which respectively take into notches on the rod B and
bar C, according to the position of the catch lever H. The pattern cam
shewn at Fig. 1 is cut so as to allow of twelve courses of one color being
knitted, and six of another, but it will be obvious that any desired
variation may be made in the relative numbers of the courses.
The cam
I is mounted on a bracket I', which is bolted to the under-side of the slur
bar E, and fitted to the boss of the cam is a ratchet wheel I', formed
with, say, eighteen teeth. Into these teeth takes a pawl 1 which is
carried by a slide K. This slide is rectangular in plan view and it is
supported on the bracket I',' over which it slides to give an up-and-down
motion to the pawl I³. The slide K has a vertical piece K¹ which is slotted
to receive screw pins which connect it with the bracket I¹; an upward
tendency is given to the slide by a coiled spring K* which connects it
with a fixed pin projecting from the bracket I'. The slur box E carries a
double incline E³ (Fig. 3), which as the slur box is traversed to and fro
is caused to bear upon the upper edge of the rectangular portion of the
slide K and depress it to the dotted position of Fig. 1 at every backward
and forward traverse of the slur box. By this means an intermittent
axial motion is imparted to the cam I by the action of the pawl upon the
ratchet wheel, the arm H* meanwhile riding upon the periphery of the cam.
Fig. 1 shews this arm as riding on the smaller radius of the cam, and the
catch h of the lever H is consequently looked into the notch of the rod
B, thereby stopping the traverse of the thread carriers 2. When however
the larger radius of the cam is brought under the arm H³ the lever H
will be lifted and the rod B will be freed from the catch h, at the same
time the catch ¹ will enter a notch on the under side of the bar C, and
stop the traverse of the thread carriers 3. Thus a.change of color in the
knitting thread will be effected, and as will be understood two colors can

page_text: be alternated throughout the length of the leg of the hose. It will be
further understood that as the catch lever H is mounted on the slide
which carries the stops F¹ the automatic adjustment of these stops to
produce the "fashioning" of the hose will not affect the action of the-
automatic apparatus just described; the arm H³ being made sufficiently
long to bear upon the pattern cam throughout the variation of position
of the stop slide. In order to stop the axial motion of the pattern cam I,
a sliding bolt L is provided on the top of the bracket I', which on forcing.
down the slide K into the dotted position of Fig. 1 may be made to hold
down the slide in that position and thus clear it from the action of the
incline E of the slur box. The traverse of the slur box will then cease

page_text: needles the thread which is to form the instep. The traverse of the bar
C having been adjusted by means of the screw stops c¹³, c³, to suit the
width of the instep, the stops F and F¹ are to be adjusted to limit the
traverse of the rods A and B. The thread carriers 3 are now to be
brought to a position corresponding in the work to the left-hand edge of
the instep, and the carriers 1 and 2 are in like manner to be brought
to the left-hand edges of the half heels. On the next forward traverse
therefore of the slur box the several carriers will receive a limited
traverse over the work, the carriers 1 laying the threads to the left-
hand half of the heels, and the carriers 2 laying the threads for the
right-hand half of the heels, the thread for the intermediate work being
supplied by the thread carriers 3.
By reference to the diagram, Fig. 3, Sheet II., the work of knitting
the heel and instep simultaneously will be more clearly understood.
Supposing the knitting of the hose to be commenced at the ribbed end
a, a, by the action of the thread carrier 3, that carrier will continue to
be worked alone until the work has advanced to the line b, b. At this
stage of the work the traverse of the carrier 3 will be limited as above
explained, and at the same time the thread carriers 1 and 2 will be
brought into action, their traverse being also limited by the stops as
already explained. Three distinct portions of work will now be pro-
ceeded with until the line c, c, is reached, the thread carrier 1 laying the
thread for the work colored red, the thread carrier 2 laying the thread
for the work colored yellow, and the thread carrier 3 laying the thread
for the work colored blue. In finishing the heel it will be understood
that the work will have to be narrowed; this will be effected by the
automatic advance inwards of the stops F and F, the action of which is
well-understood by the trade. When the work has advanced to the line
c, c, the machine must be stopped; the thread carriers 1 and 2 are then
to be drawn out of action, as shewn at Fig. 2, Sheet IV., and their rods
made fast by means of the stops G and m before referred to. This being
done the knitting is to be continued by the use of the thread carrier 3
only until the line d, d, is reached, when the instep will be completed;
but inasmuch as it is requisite to narrow the instep towards the toe
5 before re-starting the machine, the finger m² is lifted out of reach of the
bar.C, and the slides of the end stops F and F are "racked in" to bring
forward the additional stops which they carry into position for limiting
the traverse of the bar C, and thus perform the office of the finger m².

page_text: this change is to bring the automatic narrowing apparatus
to act upon the bar C when the toe is required to be narrowed. The
machine being now re-started, the thread carriers 3 will proceed to work
alone until the toe is completed.
It may be well to remark that the foot bottom which completes the
stocking is intended to be made in any well known knitting machine.
In order to improve the operation of "splicing," that is of knitting a
double thickness of fabric at such parts as are required to resist hard
wear, we use two additional thread carrier bars, so arranged with respect
to the rods of the ordinary thread carriers, that they will be free to slide
past them and take up positions at either side of the work as may be
desired. These additional carriers are however not intended to pass
each other but they will be used when applied to the manufacture of
hose, which will serve as one illustration to do what may be termed
counterpart work, or to act simultaneously with the same result on
opposite sides of the work.
In Sheet V. of the Drawings, Fig. 1 shews in partial plan view the
machine modified according to the third part of our Invention for
"splicing," and Fig. 1* is a partial end elevation of the same. In this
arrangement A and A' are the rods fitted with the ordinary thread
carriers, which are marked 1 and 4 respectively. B and B¹ are bars
fitted respectively with the additional thread carriers 2 and 3; they are
mounted in fixed guides C, C, as shewn in the detached view, Fig. 2,
and move in the same horizontal plane.
The thread carriers are all driven as before described by friction clips:
connected with the slur box, but it has been found requisite, in order
that the friction clips of the bars B, B¹, may not interfere with the
thread carriers that lie within their course, to modify the attachment of
such thread carriers to their bars and to secure them, some to the back
and some to the front of their respective bars. This is shewn clearly in
several views in Sheet VI. Fig. 1 in this Sheet is a diagram of the
whole width of the machine, shewing the four carriers of each set in
position for "splicing." Fig. 2 is a cross section on an enlarged scale,
shewing the relative position of the thread carriers and the rods or bars
which carry them. Fig. 3 represents the more usual form of attach-
ment of the thread carriers 2 to their bar B, and Fig. 4 shews the more

page_text: usual attachment of the thread carriers 3 to their bar B'. Fig. 5 shews
the
way in which the carriers 2 are mounted in the third and fourth
divisions at a, a, in Fig. 1, to allow for the friction clip passing those
carriers; Fig. 6 represents a carrier 2 as mounted at 6 in the fifth
division of Fig. 1 to permit of the friction clip of the front bar passing
it; Fig. 7 shews the mode of mounting the carrier 3 in the sixth
division of Fig. 1, at c, for the friction clip of its own bar to pass it.
The form of clip employed for driving the bars is shewn in cross section
at Fig. 5, in front elevation at Fig 8, and in plan view at Fig. 9. The
projecting pin at the back of the friction clip enters a fork carried by the
usual attachment of the thread carriers to their Dar D'.

These details of construction being explained, it will only be necessary
further to describe the spring stop which is used in working the two
additional sets of thread carriers and the catch for holding them out of
action.
In order to suspend the action of the thread carriers 2 and 3, their
respective bars are furnished with a finger d, d, Fig. 1, Sheet V., which
fingers are embraced by staples projecting from a sliding catch. Fig. 3
shews this catch in plan view and in the position for fixing the thread
carrier bars, and Fig. 4 is an edge view of the same. Fig. 5 shews a
portion of one of the bars with a finger attached thereto. This catch
consists of a bracket D made fast to the front framing of the machine,
and fitted to its upper face is a sliding piece D' furnished with a handle
for moving it to and fro. This sliding piece D is slotted to receive
3 screw pins, which secure it to the bracket D. From the opposite sides
of this sliding piece project the staples which embrace the pins d, d'.
When therefore the thread carriers 2, 3, are required to act, the catch is
slidden into the dotted position of Fig. 3, at which time the bars will be
disengaged from the catch. For the working of these additional thread
carriers we employ a novel construction of spring top for limiting in
one direction the traverse of the thread carriers. In the opposite
direction the limitation is determined by a permanent or fixed stop.
The spring stop is shewn detached and in several views in Sheet VI.
Fig. 10 is a plan view of the stop shewn out of action or with the thread
5 carrier bar lying across it; Fig. 11 is a plan view shewing the stop in
position for arresting the motion of the thread carrier bar, and Fig. 12
is an edge view of Fig. 11.

page_text: The stop consists of a bracket E bolted to the slide of the ordinary
stop F, and it is fitted with a sliding piece E¹, which is slotted to receive
screw pins for connecting it to the bracket E. The sliding piece E¹ is
cast with a lug, which is tapped to receive a screw e, and it is the head
of this screw which forms the adjustable stop for the thread carrier
bar. A tendency is given to the sliding piece E' to take the position
shewn at Fig. 11 by means of a coiled spring e', which connects with a
stud on the sliding piece and a stud on the fixed bracket. The sliding
piece is however held in the position shewn at Fig. 10 by the thread
carrier bar bearing against the lug of the sliding piece. When however
the bar is drawn out of contact therewith the stop e will assume its
normal position and stand in the line of the traverse of the thread
carrier bar.
By reference to Fig. 1, Sheet V., it will be seen that the machine is
provided with two such spring stops as that just described; thus the
stop E will act on the thread carrier bar B and the stop E* will act upon
the thread carrier bar B¹ and serve to limit the outward motions of those
bars. The limitation of their motions in the opposite directions is
effected by means of tappets a* and 6* secured to the face of the bars
coming in contact at opposite sides with a fixed guide C which supports
the ends of the bars.
It only remains now to describe the mode of arranging the thread
carriers to commence the splicing for the hose and to shew the changes
requisite in order to continue the splicing to the extremity of the heel.
By reference to the diagram, Figure 4, Sheet II., which illustrates the
manufacture of a half hose, the nature of the work intended to be
effected will be clearly seen.
In commencing to manufacture the leg of the half hose the thread
carriers 1 are put into operation (the other thread carriers being held out
of action). These continue to act alone until the work has advanced
from the end of the ribbed piece to the line a, a. When this point is
reached the catch D¹ (which held fast the thread carrier bars B and B¹
in position for starting) is pushed back, and the thread carriers of the
bars being thereby released they will be free to come into action. The
next traverse of the slur box will move forward the thread carriers 13
and 2 in the direction of the arrow, Figure 1, Sheet V., the thread

page_text: carriers 1 making a traverse equal to the whole breadth of the hose, and
the thread carrier 2 moving a short distance equal to the width of the
double or spliced fabric required to be made. On the return traverse of
the thread carriers 1 the thread carriers 3 will move in with them, their
traverse inward being limited like that of the thread carriers 2 to the
width of the double or spliced fabric required to be knitted. It will be
understood that the traverse of the thread carriers 2 and 3 will be limited
on the one hand by the spring stops E, E*, and on the other by the
striking of the tappets a*, bx, on the thread carrier bars against the
bracket guide C as before explained. The operation of these three sets of
carriers is continued in like manner until the work has advanced to the
line b, b, Figure 4, Sheet II. When this point is reached the machinery
is stopped, as the length of the leg is completed. The carriers 1 and 3
will be at that time on the left-hand side of the work, and in position
for forming the left-hand half of the heel, and the carriers 2 will be in
position for commencing to form the other half of the heel. It is now
necessary to bring the carriers 4 to act with the carriers 2 to form
the right-hand half of the heel, and for this purpose the rod A¹ of the
thread carriers 4 is to be released by pressing down the stop which
ensured its quiescence. This stop is shewn in place at G, Figure 1,
Sheet V., and detached and in its disengaged position at Figure 6. The
rod A' when released from the catch G is pressed up against a fixed stop H,
Figure 1, and the stop F¹ shewn detached at Figure 7 is then set to act
upon the opposite end of the rod. The machine is then started and the
operation is continued until the line c, c, Figure 4, Sheet II., is reached,
at which time the heel will be completed. It will be understood that
during the completion of the heel the automatic narrowing apparatus
will be brought into action without interfering with the splicing opera-
tion. Thus the splicing will be carried up to the selvages and continued
through the narrowing, and a strength of heel hitherto unattainable in
automatic machinery will be thereby ensured. The hose or half hose
thus far manufactured can then be finished in the ordinary manner.
Having now described the machine as modified for the splicing of
hose, it may be well to explain its adaptation to the continuation of the
5 striping (which forms the first head of our Invention) throughout the
heel. It will be remembered that in explaining the operation of
striping, this process was arrested where the heel commenced, that is, at

page_text: the usual point where the striping ceases, but from what has been
described with reference to Sheets V. and VI. it will be readily under-
stood that the striping may be continued throughout the heel. 'For
this purpose the four thread carriers of each set are arranged in pairs,
one pair to form one half and the other the other half of the divided
heel. The carriers of each pair are provided with threads of different
colors, and instead of the pattern cam described with reference to
Sheet III. acting alternately upon a front and back carrier rod or bar,
the pattern cam is caused to act upon a carrier bar or rod of each pair
simultaneously.
The modification requisite for effecting this operation is shewn in side
elevation at Figure 1, Sheet VII., it being necessary to provide for the
locking of two of the thread carrier rods or bars when in contact with
their dead stops, and of the other two at variable positions of their
traverse. I is the pattern cam; H, the catch lever mounted on a
standard H¹ carried by the slide of the stop F; H2 is the arm of the
catch lever that rides on the pattern cam. The catch lever H is fitted
with two catches h and h¹, which take alternately into a notch of the
carrier bar B¹ and of the rod A. This catch lever H is fitted with a
horizontal pin H³, which passes freely through a hole in a catch lever L
pivotted on a fixed bracket L'; this catch lever L terminates in a
catch which enters a notch in the carrier rod A', and it is furnished
'with a second catch which enters a notch in the under side of the
thread carrier bar B. The catches h, 11, by reason of their connection
with the stop slide F will receive a lateral motion when the "fashioning "
is proceeding, but the other catches 1, 1, will always act in the same
vertical plane. We thus provide for the arresting of two of the carrier
bars or rods at various positions of their traverse, whilst the other two
will always be arrested while in contact with their dead stops.
Figure 2 shews in partial plan view a machine arranged for striping a
the heel. The carriers 1 and 3 are arranged to work one half of the
heel and the carriers 2 and 4 to work the other half. The two carriers
of each pair will be furnished with threads of different colors, and being
thrown into and out of action alternately by the device shewn at
Figure 1, they will knit lines of different colors, as described under the 3
1

page_text: It will be understood from what has gone before that only two
carriers are required to work the striped leg; it is therefore necessary
to provide for the stopping of two out of the four sets of carriers when
manufacturing the leg in this modified form of the machine, and to
give the remaining two a traverse across the whole width of the work.
In commencing the leg it is necessary to have No. 4 and No. 2 thread
carriers locked out of action on the right-hand side of the work, No. 4
being locked by the stop G and No. 2 by the stop D* (see Figure 2,
Sheet VII.). This stop D* is similar to that shewn at D, Figure 1,
Sheet V., but with the exception that it has only one staple d. The
tappet on the bar B¹ of the thread carrier 3 will have to be removed or
thrown out of action, in order to allow of the thread carriers 3 traversing
the full width of the work. For this purpose we adopt the form of tappet
shewn in the plan and elevation at Figures 3 and 4, which will allow of
the instant removal of the tappet when required out of line with the
guide bracket C. The bar B' is formed with a lug on its upper edge to
receive a pivot for the tappet a; this tappet is formed with a thumb
piece a¹ for turning it on its pivot; 6 is a spring carried by the pivot
pin and fitted with a pin at its extremity, and forming therewith a snap
bolt, which is intended to hold the tappet either in action, as at
Figure 4. or out of action, as at Figure 5.

straight" work) at any determinate part of the work by means of
dditional thread carriers mounted and operated as above described.
Fourthly. "Plating" hosiery goods by the use of thread carriers

In witness whereof, we, the said John William Lamb and Samuel
Lowe, have hereunto set our hands and seals, the Fourteenth
day of May, in the year of our Lord One thousand eight hundred
and seventy-two.
