PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 25th February 1874.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of my said Invention of "IMPROVEMENTS IN LOOM HARNESS AND
IN MACHINERY FOR MANUFACTURING THE SAME," a communication, to be as
follows:-
The present Invention relates to improvements in machinery arranged
for the manufacture of that class of loom harness having its eyes or

page_text: heddles made from continuous yarn by using two continuous lengths of
yarn, from one of which the heddle eyes are made, with the other yarn
looped at one end of each and every eye in turn, and both yarns secured
to the rig bands completing the harness.
The said Invention particularly relates to that class of said machinery
in which are employed a two-cyed stationary needle, a yarn twister, a
heddle eye former, a pusher for pushing the heddle eye from the heddle
eye former upon the stationary needle and carriers for automatically
carrying the heddle yarns from the stationary needle to the rig bands, or
in other words the said Invention relates principally to improvements on
the machine for making loom harness, described in the Specification of
former Letters Patent granted to James Ellis and Joseph Sladdin, dated
15th January, A.D. 1804, No. 117.
According to this Invention there is combined in one and the same
machine two or more of the said two-eyed stationary needles for the
heddle yarns, a corresponding number of the said yarn twisters of the
'said heddle eye formers, and of the said heddle eye pusliers, a single set
or pair of carriers for conveying the heddle yarns from the said
stationary needles to a common pair or set of rig bands, and a
mechanism at each rig band for knitting or otherwise securing the heddle
yarns thereto.
Each stationary needle receives two lengths of heddle yarns, and from
the needles all the heddle yarns pass, and they are tied to a common set
or pair of rig bands, as in the said Specification. The needles are located
one above another with a space between them. All the needles are
rigidly fixed at one end, and free at their other end, and between the
two ends supported from falling and from lateral or side play, while at
the same time no obstruction is given to the travel of the heddle eyes.
along the length of the needles. This support of the lower needle is
the same as described in the Specification of the said former Letters
Patent, but the support of the remainder is secured by the interposition
between every two of them, and intermediately of their length of a
similar separating and supporting block. Each separating block rests
on a needle, and through its rest on one supports the needle next above,
and in addition to this rest on the one needle and support of the other
needle it embraces or surrounds the edges or sides of both needles, and
thus holds them against lateral movement. The separating blocks are

page_text: secured against movement along the length of the needles by a rod,
which extends from cach block between the needles to the fastening
place of the same, as stated, and to such place it also is fastened. The
separating blocks offer no obstruction to the travel of the heddle eyes
along the needles. For each of these stationary needles there is a heddle
eye former, a heddle eye pusher, and a heddle eye twister, and in the
arrangement of the machine the several heddle eye formers act together,
as also the several heddle eye pushers and twisters, so that if two stationary
heddle yarn needles are used there will be a simultaneous forming of
two heddle eyes by the two heddle eye twisters upon the two heddle eye
formers, and then a simultaneous pushing of the two heddle eyes from
the formers on to the stationary needles, one heddle cye to each
needle.
In the present machine these several parts operate substantially the
same as described in the said former Specification, and therefore do not
require to be particularly referred to, except to observe that the several
heddle eye formers are attached to a common shaft, and the several
heddle eye twisters are separately geared to run from a common driving
shaft, and the several heddle eye pushers are attached to a common
moving part, and are arranged to travel through the common shaft of
the heddle eye formers, which is slotted vertically to admit of the same.
The two heddle yarn carriers are located one at each side of the
several stationary needles. Each carrier has a similar hook at its carrying
end, and from the notch of such hook the edge of the carrier inclines to
the length of the carrier for a portion of such length. The carriers are
located in a vertical position in the machine, and with their hook ends
uppermost. Their lower ends are pivoted to a common holder bar, which
is arranged to raise and lower in a direct vertical line. Each carrier
intermediately of its length is connected to a similar but separate crank
arm, and both of these crank arms in the running of the machine are
driven continuously and simultaneously. The connection between each
carrier and its crank arm consists of a slotted arm pivoted to the carrier
and hung to the crank arm by its slot. The bar, to which are pivoted
the carrier levers as above stated, is lifted by a cam, which is of suitable
form to raise the carriers from a position wherein their hooks are below
the lower needle of the series of stationary needles to a position or
height in which their hooks will be above the upper needle of the series
42

page_text: of stationary needles, and also to allow the carriers to fall to the position
from which they were lifted by the cam, as above stated.
In the lifting of the carriers they pass directly by the sides of the
stationary needles, and between such sides and the heddle yarns, which
are stretched along such sides from the eyes of the needles to the heddle
eyes last deposited, and pushed along the needles by the operation of the
heddle eye pushers. During the said lifting movement of the carriers
the cranks are moving through the slot of their respective slotted con-
nections with the carriers, so that the upward movement of the carriers
will be in direct and straight vertical lines as soon as the upward move-
ment of carriers is completed; then the cranks commence to draw the
carriers simultaneously outward to the rig bands, the one carrier to one
rig band and the other carrier to the other rig band, and thus the
several heddle yarns at both sides of the several stationary needles are
drawn out to the rig bands.
When the carriers have reached the rig bands the several heddle
yarns drawn by them are in their hook notches so as to be the more
properly presented for removal from the carriers by knitting mechanism
to be herein-after described. This bringing of the several heddle yarns
on a carrier to the hook notch is effected by the incline of the edge of
the carrier acting in conjunction with the lowering of the carrier, which
during such outward movement is also taking place.
After the knitting
mechanism has taken the heddle yarns from the carriers the latter are
moved back into position to be again lifted for again drawing out the
heddle yarns to the rig bands. The backward travel of the carrier is
occasioned by springs applied to them, the crank connections and slotted
arms admitting of the said movement.
The heddle yarns may be knit to the rig bands by mechanism such as
shown and described in the aforesaid Specification. This Invention
however embraces a novel arrangement of mechanism for such knitting
purpose. An ordinary latch knitting needle is attached to a bar, which
is arranged to travel horizontally forward and backward, and thus to
carry the hook of the needle forward and backward across the
rig band, to which such needle is to knit the heddle yarns. This
knitting needle in its travel above specified moves through a slotted
guide post which is arranged to be raised and lowered under the
action of a cam, so that when the needle moves forward and backward

page_text: in one instance it will pass over the rig band, and in the other instance
under the rig band, and so on alternately over and under the rig
band.
The forward and backward movements of the bar which carries the
knitting needle are produced by the continuous rotation of a disc on to an
eccentric pin to which a slotted arm of such bar is connected. In each
forward movement of a knitting needle the hook of the needle is carried
into such a position with reference to the heddle yarns of the rig bands
that the needle hook will seize the leddle yarns as the needle moves
backward, and thus draw such heddle yarns across the rig band.
To better illustrate the operation of the knitting mechanism I will
suppose that there is only one stationary needle, and that the carrier has
made its first draw of a harness yarn from such needle to the rig band,
and that the carrier is at rig band with the yarns. The hook of the
knitting needle now takes the heddle yarn looped around the carrier,
and draws the yarn across and under the rig band to the back thereof.
The knitting needle now lifts and then travels forward, across, and over the
rig band, and then again scizes the heddle yarn and draws the heddle yarn
across and over the rig band to the back side thereof. In the said
forward movement of the knitting needle after it has drawn the yarn
under the rig band to the back thereof, the rig band holds the loop of
heddle yarn in the needle against movement with the needlo, and thus
the needle travels through such loop; and this loop, when the needle has
completed its said forward movement, is on the needle shank at a suffi-
cient distance from the hook to cause as the needle moves backward to
the rear side of the rig band a closing of the latch to the needle,
whereby is allowed the escape of such loop from the needle. In this
escape of the yarn loop it is of course caught by that loop of harness
yarn which is carried by the backward travel of the needle, during which
the loop escapes, and thus a loop of the harness yarn is interlaced with
another loop of the harness yarn.
When the needle has reached the limit of the backward movement
above stated it is lowered, so that in its next forward movement it will
pass under the rig band to the front side thereof.
In this forward move-
ment the loop carried by its previous backward movement opens the
latch of the needle and passes upon the needle shank as above stated;
when the needle again travelling under the rig band to the rear side

page_text: thereof such loop escapes from the needle as above described, and in
such escape it is caught by the loop of heddle yarn drawn by the needle
hook in said backward movement. Thus the harness yarn is looped and
interlaced at the rear side of the rig band, and by this travel of the
knitting needle over the rig band made to surround the front side of the 5
rig band, the whole securing the attachment of the harness yarn to the
rig band in a novel and most efficient manner by means of the harness
yarn itself, and without the use of a separate and additional line or
thread.
The knitting of the harness yarn to the rig bands is a most important 1
feature of this Invention, and constitutes the improved manufacturo of
loom harness to which this Invention in part relates, irrespective of the
mechanism by which the knitting is secured.
Obviously the operation of the knitting mechanism above described is
the same with two or more harness yarns as with one, and differs in no 1
respect except as to the number of harness yarns which are looped and
interlaced with each other and with one and the same rig band.
To ensure the hooking of the harness yarn in the needle hook a
pusher is arranged to push against the needle at the proper time, that is,
when the needle is taking the harness yarn. This pusher receives motion 20
by a suitable connection with the actuating disc for the travel of the
needles.
To firmly hold the rig bands against the pull of the harness yarns on
them by the knitting needle a guide post is provided for each rig band;
through these guide posts the rig bands pass, and they are fixed in a 2
position relatively to the pull of the knitting needles to hold the rig.
bands firmly.
The cross head which lifts the carriers also lifts the heddle eye
retainer. This heddle cyc retainer is attached to the said cross head,
and it is made of a fork shaped to embrace the several stationary needles 30
between its two lines, and thus to keep the heddle cyc on cach needle
from being pulled or distorted as the heddle yarns are drawn out to the
rig bands.
The heddle eye formers, when in position for having the heddle eyes
formed on them pushed into the stationary needles by the heddle cyc 3
pushers bridge over the space between the ends of the needles and the

page_text: formers, and this bridging over is secured by a forked construction of the
outer ends of the horizontal arms to the formers.
For cach heddle eye deposited in the several needles cach carrier
travels once to and from the rig band, and each knitting needle makes
two forward movements across its rig band; in its first forward movement
it takes the harness yarns from the carrier which is then at the rig band,
whereas in its second forward movement, while it again takes the
harness yarns it is not from a carrier, as then the carrier is about to
commence its next draw of the harness yarns to the rig bands.
Instead of raising and lowering the knitting needles so that they will
pass under and over the rig bands, the rig bands themselves may be
raised and lowered, and the same result in knitting be obtained.
The direct upward movement of the heddle yarn carriers at the sides
of the needles is essential, as otherwise if the carriers then had an out-
ward movement from the needles they would fail to take the heddle
yarns from the series of needles.
.
With two stationary harness yarn needles as herein described one
leese rod is dispensed with, as the needles themselves hold the harness-
apart as it is made.

Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN LOOM HARNESS AND IN MACHINERY FOR MANUFACTURING
THE SAME," a communication to me from abroad by Joseph Sladdin, of
Laurence, Massachusetts, United States of America, upon the condition
(amongst others) that I, the said William Robert Lake, my executors
or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accom-
panying Drawings forming a part of this Specification:-
The present Invention relates to improvements in machinery arranged a
for the manufacture of that class of loom harness having its cycs or
heddles made from continuous yarn by using two continuous lengths of
yarns, from one of which the heddle eyes are made, with the other
yarn looped up at one end of each and every eye in turn, and both yarns
secured to the rig bands, completing the harness.
The said Invention particularly relates to that class of such machinery
in which are employed a two eyed stationary needle, a yarn twister,
a heddle cyc former, a pusher for pushing the heddle eye from
the heddle eye former on to the stationary needle and carriers for
automatically carrying the heddle yarns from the stationary needle to
the rig bands, or, in other words, the Invention relates principally to
improvements on the machine for making loom harness, described in
the Specification of former Letters Patent, granted to James Ellis and
Joseph Sladdin, dated the 15th day of January A.D. 1864, No. 117.
According to this Invention,-
Firstly. There is combined
substantially no horain after docenih
"

page_text: yarns, a single set or pair of carriers for conveying in common the
heddle yarns of cach needle to a common pair or set of rig bands, and
suitable mechanism at each rig band for knitting or otherwise securing
the heddle yarns thereto.
Secondly. I combine with two or more of the aforesaid stationary
needles a supporting and separating block for cach pair thereof, which
is arranged intermediately of and made secure against movement along
their length, and is otherwise arranged and constructed to hold the
needles from displacement or movement, and at the same time allow the
passage or feed of the finished harness along the needles.
Thirdly. Carriers for carrying the heddle yarns from the needles to
the rig bands are arranged one upon cach side of the series of stationary
needles, and are adapted, each and both as to movement, to take from
their respective side of the needles the several heddle yarns at that side
and to convey them simultaneously to a common rig band at the
corresponding side for being secured thereto by the kuitting or other
mechanism employed for that purpose.
Fourthly. I employ mechanism for knitting the heddle yarns to their
rig bands, which is arranged with regard to the rig band for the knitting
needle to travel forward and backward across the rig band, passing in
cach forward and backward movement alternately above and below tho
rig band, and for the knitting needle in each forward movement to sieze
and hook the heddle yarns, and in cach backward movement to carry or
pull them across the rig band above or below the same, as the case may
be, and in cach instance through the heddle yarn loop remaining on the
needle shank from the previous forward movement of the ncëdle, and,
for the knitting needle as it draws the heddle yarns through the loop
which is on it, to drop such loop, as in ordinary knitting.
Fifthly. I combine with the preceding a device arranged and acting
to force the knitting needle, after siczing or hooking the heddle yarns,
into a position to ensure the retention of the yarns on the needle as
the needle travels backward, and thereby obviate any possibility of their
escape from the needle at such time.
In addition to the above the said Invention consists in various
improvements in the details of construction and arrangement of parts as
herein-after described.

page_text: The said Invention also consists in a loom harness which has its heddle
eyes made from continuous lengths of yarn, and has its heddle yarns

the heddle yarns from the needles to the rig bands and the knitting of 1
them to the rig bands.
Figures 13, 14, and 15, are views illustrating the knitting or fastening
of the harness yarns to one rig band, they being fastened to the other rig
band in a precisely similar manner and between the two rig bands

lengths of yarns.
Figures 16, 17, 18, 19, and 20, shew an improved hanging of
the stationary needles in the machine and arrangement of tension
pulleys.
A represents a framework made of any suitable construction to 2
receive the working and stationary parts of the machine, and in the
present instance it is shown as consisting of a main frame B, rectangular
in shape, and frame C extended from one end thereof; D is the driving
shaft, arranged transversely of and turning in bearings of frame B. The
driving shaft D is to be driven by belting or gearing or in any suitable 8
manner, and through its revolution by suitable intermediate gearing,
the primary shafts E and F are driven with a continuous rotary
movement. The shaft E operates the two twisters, the two knitting
needles, and the heddle eye retainer; the shaft F operates the two
heddle eye formers, a common or double pusher for pushing the heddle 3
from the two heddle eye formers on to the two stationary needles,
cyes

page_text: one heddle cyc to cach needle and both shafts operate the carriers for
carrying the heddle yarns to the two rig bands; G, G, G, G, are four
bobbins arranged in pairs at each side of the central line of the machine.
These bobbins contain the yarns of which to make the harness heddles
and from them the yarns after being passed through suitable tension
devices are run along the grooves a of two stationary needles H, H, two
yarns to cach needle, as shown, and thence through cyes c of the
needles to the rig bands, ono yarn from cach needle to each rig band,
and to these rig bands they are tied. The rig bands run from posts I, I,
of the freed cross head or carriage J to and over pulleys K, K, of
posts L, L. The yarn needles H, H, are arranged in parallel horizontal
planes one above another with a space M between, as shown, and in this
position they are fastened at one end to a post P by set screws d, d, and
near their ends at which they receive the heddle cycs is located a
separating block N. This block N rests upon the upper face of the
lower needle and against the lower face of the upper needle and
embraces the sides or edges of the needles, as shown, and in this position
it is secured against movement along the needles by the rod ○ which
extends between the needles H along their length to the post P to
which it is fastened by a set screw d. Q, Q, are two yarn twisters;
these yarn twisters are attached to distinct horizontal shafts R and they
are located at one side of and at right angles to the stationary needles.
Each shaft R has a pinion wheel S, and both pinions S are driven from
a common gear wheel T, which receives its motion from the primary
shaft E by suitable interposed mechanism, and such as shown in the
Drawings, to give each of the yarn twisters a reciprocating rotary
movement at the same time; U is a shaft arranged vertically a short
distance from the receiving ends of the yarn needles H. This shaft U
carries two heddle cyc formers g, g, one above the other, and in
horizontal positions corresponding to the needles I, II, and the move-
ment of the shaft U is a reciprocating rotary one, as with the heddle
former spindle H, described in the Specification of the said Letters
Patent. The means for communicating this movement consists of the
pinion wheel V and the rack bar W engaging each other. The rack
bar W is moved in the one direction by a cam X of the primary shaft F,
to which cam it is connected by a lever rod Y turning on a fulcrum / of
the frame B, and it is moved in the other direction by the reaction of a
spiral spring Z. The heddle eye formers 7, 9, project horizontally from
the shaft U and are fork; shaped, the forked ends bridging the

page_text: pointed ends of the needles I, so that under the action of the heddle
eye pusher the heddle eyes will certainly pass from the formers g, I, on
to their proper needles H, while at the same time the formers 9, g, in
their swinging movement can pass freely by the needles H; As is the
heddle eye pusher; this pusher A² consists of a vertical bar B placed at
one end of a horizontal bar C³ which is arranged to slide backward and
forward through the shaft U having the formers g, g; the shaft U for
this purpose is slotted vertically as shown.
The forward movement of the pusher A³ is effected by the cam D³ of
the primary shaft F, to which it is connected by a lever rod Eº turning
on a fulcrum m of the frame B, and its backward movement is secured
by the reaction of the spiral spring F². G², G, are two vertical levers;
these levers G³, G, are the lieddle yarn carriers and they are located one
at each side of the needles H, and at their lower end they are hung to
a fulcrum 12 of the cross bar H of a vertical rod I. The rod Iº is
arranged to be moved vertically within the frame B, being guided by
guide pieces J, J. Each carrier lever G³ at the upper end is hook-
shaped, and between the two ends it is connected by a slotted rod K³ to
the crank arm L³ of a horizontal shaft M that is driven continuously by
bevel gearing N from the primary shaft F. Each rod K³ is pivoted to
its lever carrier G³ and hung by the slot Of on its crank arm L³. The
carriers G², G², first pass upward in a direct and straight vertical line
through the recesses O at the edges of the needles, then outward to the
rig bands which are located as described, and then back into position to
be lifted as before. The upward movement of the carriers is caused by
the cam S of the primary shaft E, which cam acts on the common
carrying rod I of the two carriers G³ through the arm r, and their
outward and inward movements are caused by the action of their con-
ucction with the shafts Mr.
While the carriers are lifted, as above stated, their connection with
the shafts M³ rests or dwells so that the movement upward shall be
directly through the recesses o of the two needles, and this dwell or rest
of the said connection results from the slotted construction of the pitman
rods K. The lifting cam S for the carriers is of suitable form to lift
the carriers the proper distance, and also to allow them to fall into
position for being again lifted while their outward and inward move-
ments are occurring as stated. P, P, are adjustable pins one to each
carrier G³, these pins limit the said backward movement of the carriers

by abutting against the part R of the rod I.
retainer; this retainer S is carried by the
yarn carriers G, and it projects upward so
ment of the rod I it will embrace both yarn needles at each side and
thus retain or hold the heddle eyes against derangement under the
operation of the yarn carriers. T, T, the two knitting mechanisms.
This mechanism is located at and outside each rig band, and each
mechanism is composed of parts as follows:-t is a latch knitting
needle. This needle is fastened to the arm by a set screw u, and
this arm is pivoted to a plate or slide U³ which is arranged to slide
horizontally on a vertical guide frame V. The arrangement of the
slide U³ is such that it can be moved toward and away from the rig
bands, and this motion it receives from the action on its slotted arm W
of the eccentric vertical pins Vs of the disc W₁ on the shaft X*, which
disc is continuously rotated from the primary shaft E through the
bevel gearing Y³.
The knitting needle projects downward over the rig bands, and in the
movement of the slide U it plays through the forked upper end of a
standard Z. This standard Z is located just outside of the rig band
and it is connected to a cam A³ of the primary shaft E through plate B³
so as to bo raised and lowered as such cam revolves. The needle never
escapes from its slotted standard and therefore it is always subject to its
rising and lowering movement. 0³, C³, are two fixed posts through
eyes to of which the rig bands pass one to cach post. The posts C³ hold
the rig bands firmly against the action of the knitting needles, as will
herein-after more fully appear.
In the formation of a heddle eye and its disposition on a stationary
needle, the herein described machine operates precisely the same as the
machino described in the Specification of said Letters Patent, except
that the result is doubled, that is to say, two heddle eyes are formed and
deposited on two stationary needles, one to cach needle, in lieu of one
heddle eye on one stationary needle as before. After this deposit of the
heddle eyes on the needles the heddle yarns are drawn out to the rig
bands by the yaru carriers G and there they are seized by the hook of
each knitting needle and then knit and secured to the rig bands under
an operation of the knitting needles, to be herein-after described.
In drawing out the heddle yarns from the yarn needles to the rig
bands the arms leading from the same side of the two yarn needles are

page_text: carried in common by the yarn carrier there located. The first is moved
directly upward by the same side of the two needles between the needles
and the yarns lying along the side of the needles and extending from
the needle cyes to the heddle eyes last deposited on the needles, and
then outward toward the rig band, drawing with it the heddle yarn of
cach needle to the rig bands. As the two heddle yarns are thus drawn
out to the rig band they come to a common position on the yarn carrier
that is in its hook (see Figure 7), and this movement is caused by the
inclined face or edge y of the carrier up and along which the yarns
ride or pass into the hook as stated.
The knitting mechanism operates as follows:-Before the carriers
leave the lieddle yarns at their respective rig bands, as before stated, the
knitting needle of each mechanism siezes them in its hook, and under
its movement then draws them across and to the rear side of the rig
bands, passing, for instance, at this time under the rig band (see
Figures 9 and 10). The slotted standard now rises, lifting with it the
knitting needle, which then travels across and to the front side of the
rig band, passing above the rig band, see Figure 11. In this last travel
of the knitting needle the two loops of heddle yarns previously taken
by the needlehook across the rig band are left at the rear side of the rig
band and upon the needle shank, see Figure 1. The needle hook now
siezes the heddle yarns at the front side of the rig band, see Figure 11,
and again draws said side yarns across and above the rig band at the rear
side thereof, drawing the two loops through the two loops already on the
needle shank as before stated. In its backward movement above
described the latch of the needle is closed as in ordinary knitting which
allows the yarn loop on its shank as stated to escape from the needle.
The slotted standard is now lowered carrying with it the knitting needle
which then travels across and beneath the front side of the rig band.
In this travel of the knitting needle the loops of heddle yarns last taken
by the needle hook across the rig band are left at the rear side of the rig
band upon the needle shank. The needle hook now siczes the heddle
which lead from the heddle eye next deposited upon the yarn
yarns
needles during the previously described operation and which have been
carried to the rig band by another movement of the yarn carriers and
so on, as the heddle yarns are drawn from time to time to the rig bands.
This interlacing of the heddle yarns with each other, together with
the alternate travel of the loops over and under the rig bands, secures the

page_text: heddle yarns to the rig bands. The interlacement of the heddle yarns
is at the rear side of the rig bands, see Figures 13 and 15; and the front
side of the rig band is encircled by the heddle yarns (see Figure 14)
only upon the backward movement of the knitting needle under the
rig band and not upon the movement of the knittle needle under the rig
band.
Figure 14 shows the front or inner side, and Figure 13 the back of
the rig band as the heddle yarns are knit to it, except where the knitting
is loosened to more fully shew the running and interlacing of the heddlo
yarns, and that in lieu of two heddle yarns only one is shown, as the stitch
with one heddle yarn is the same as with two; and to avoid confusion of
lines it was deemed preferable to show it with one heddle yarn. To insure
the retention of the heddle yarn loops on the knitting needles as they
travel backward with the heddle yarn loops I have provided a pusher
lever A. This lever is operated by a pin at of the disc W which drives
the knitting needle, and this lever has a cam face & against which in the
revolution of the disc W the said pin a' abuts, and thus the post c' of
the lever is forced against the needle springing the needle sufficiently to
place its hook so that it will certainly retain the yarn loops thereon, as
the needle commences to pass backwards across the rig bands.
The guide posts C³ for the rig bands hold the said rig bands firmly
against any pull on them by the heddle yarn loops in whatever direction
from the operation of the needle the strain may come, whether in an
upward or downward, or backward or forward direction; and thus the
rig bands are secured against any displacement or derangement as to
their position at the plane of knitting, obviously for a successful operation
of the knitting needle a very important feature.
The stationary yarn needles H are both slotted as at f' to allow the
pusher bar to pass into them to carry the heddle eyes from the formers to
the needles.
The knitting devices herein described may be dispensed with, and the
means for securing the heddle yarns to the rig bands described in the
Specification of the aforesaid Letters Patent may be employed instead.
Also in lieu of raising and lowering the knitting needles as described,
the rig bands may be lowered and raised instead, but it is preferable to

page_text: The interlacing of the harness yarns with the rig bands as shown at 6
is onco for the two lengths of heddle yarns leading to a heddle eye, and
this interlacement is produced by drawing the two lengths of the heddle
yarns over the rig band after they have been drawn under the rig band
and interlooped at the back of the rig band as above described. Theso
lines 6 in Figure 13, extend from point 7 to point 7*. The knitting
of the needle yarns to the rig bands above described can be and is thus
accomplished under the arrangement of knitting mechanism herein-
before described, and while the description of the knitting is with tho
use of single yarn it is the same if two or more are employed.
Figuro 16 is an end elevation illustrating the aforesaid improved
method of locating and securing the two heddle yarn needles in the
machine; Figure 17 is a side elevation partly in vertical section ;
Figure 18 is a plan; and Figures 19 and 20 are vortical sections on thọ
lines x, x, and y, y.
H, H, are the two stationary needles, and N the separating block
which with its rod O and the needles are all secured to a common
standard or post P. This post P in lieu of being fixed to the machine is
part and parcel of a frame A composed of an extension bar Bª and a
cross head C. This cross head C is suspended upon guide rods aº fixed
to the part D of the framework A of the machine, and through this
part D plays the extension bar B of frame A°; the whole construction
allows the needles to be simultaneously drawn out of their position in
the machine, and without disturbance of their relative adjustment or of
the yarns carried by them.
The position of the needle carrying frame A° in the machine is ensured
by the set screw 6 properly located to bind the extension bar B° in its
guide part D. The guide rods a hold the needle carrying frame against
tipping upwardly as it is drawn out. The needle carrying frame A® also
carries a series of tension pulleys F° between which to pass the heddle
yarns, a set or pair of pulleys being provided for each heddle yarn, and
from these pulleys the yarns pass through guide posts Go to and through
a common guide post H into and along the grooves of the needles H.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,-
First. The combination with two or more stationary needles of the

page_text: former to the needle, and in the movement of the former to clear the
needle as herein described.
Twelfth. The forked retainer S arranged and operated as hercin
described for the purpose specified.
Thirteenth. A loom harness made of continuous lengths of yarns
looped or interlaced with each other, and the rig bands as herein set
forth.
In witness whereof, I, the said William Robert Lake, have here.
unto set my hand and seal, this Twenty-fourth day of August,
in the year of our Lord One thousand eight hundred and seventy-
four.
