KNITTING LOOMS
Year: 1885

page_text: I, JOSEPH JOHNSON ADGATE, of 115 Worth Street in the City of New York, in
the State of New York, United States of America, Manufacturer, do hereby declare
the nature of my invention for KNITTING LOOMS, and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement:---
My Invention relates to Knitting Machines or Looms; and consists of an
improved construction and arrangement of the needle jacks and needle cylinder by
which the position of the needles in respect to each other is changed to permit an
extra or weft thread to be placed between them, to adapt the machine to manu-
facture cloth or other woven material; and also in a novel construction of various
parts of the machine by which a more perfect operation of the same is secured.

page_text: My improvements may be applied to any of the ordinary Knitting Looms or
weft thread Knitting Machines commonly employed for manufacturing woven
fabrics. In the drawing and description herein the application is shown to the
ordinary rotary Knitting Machine, consisting of the circular knitting frames or
rings.
The first part of my invention relates to the mechanism for separating the
needles, so the weft thread can be placed between them, and consists of an
improved arrangement and construction of the needle jack and needle cylinder by
which some of the needles as they rise in the operation of knitting will move back
of the others.
To manufacture or produce cloth or similar woven material by means of
Knitting Machines, it is necessary to introduce a weft thread between the needles,
or back of some of the needles and in front of others, so that the thread will be
woven in with the knitted fabrio as the latter is made. To introduce this thread
thus between the needles, or back of some and in front of others, some of the
needles, those in front of which the thread lies, are caused, to move back, when
raised to their highest point, so as to occupy a position back of the other needles;
the needles thus form two lines, and the weft thread is placed between the two
lines of needles, and will thus be back of the front needles and in front of the back
ones. As the needles descend in the races in the operation of knitting, the back
needles move forward, or in line with the front ones, and thus bring forward the
weft thread which lies in front of them.
Much difficulty has been experienced heretofore in moving the needles back
when raised, and bringing them forward as they descend, and in such a manner
that they will slide evenly in the needle recess or races, and not injure the needle
or interfere with its working.
My improvement is intended to provide a ready and efficient method, by which
the upper part of the needle as it is raised is moved back or in toward the centre
of the machine, and as it descends is brought forward so as to slide in the needle
races, and at the same time the perfect working of the needle in knitting is not
interfered with, and the yarn is not injured in any manner.
My improved construction is shown in Figures 2 and 3.
As will be understood from the drawing the needle in my improvement is held
in a needle jack E which slides up and down in the needle races or grooves D.
The front edge of this jack, or the side next to the cam cylinder A is straight
from the toe K to the top of the jack, as is shown more clearly in Fig. 3. The
rear edge of the jack, or the side next to the needle cylinder B is inclined and
shaped in a peculiar manner, as is shown in the drawing.
The rear edge or side of the jack from the top g to the point fa little below the
top is straight and parallel with the front edge; from this point: f the rear edge is
curved in toward the front edge of the jack for a little distance as at fe, and then
from e inclines slightly backward to the foot of the jack at e¹. The rear edge of
jack is thus inclined from both ends in toward the front edge, the inclination from
the bottom or lower end being the longest, so that the narrowest part of the jack
is a little distance below the top or upper end, as will be understood from the
drawings.
The back of the needle groove or race D conforms at its upper end to the
contour or shape of the rear edge of the upper end of the jack from g to e. From
the upper edge of the needle cylinder at d to the point a little below the top the
groove is vertical to correspond with the part gf of the jack; from i the back of
the groove swells outward gradually toj (with a line similar to that of the
part fe of the jack) and then continues in a vertical line to the bottom of the
cylinder.
The straight portion di of the needle groove is somewhat longer than the
straight portion g f of the jack, so that after the projection on the needle jack has
passed into the depression in the back of the needle groove as the needle ascends,
the needle may rise some little distance vertically (its part gf sliding against the

page_text: part di of the groove) before the upper end of the jack reaches the upper end of
the needle groove.
The line of the forward or front edge of the jack from the top to the toe is such
that when the upper end of the jack is thrown forward, as the jack descends, as
shown in Fig. 3 the front or forward edge will be just even with the outer edge of
the needle groove, thus giving the jack a smooth and even bearing throughout the
lower part of its course against the cam cylinder.
The various inclinations and curves of the jack and needle groove should be such
that the needles will be brought into line easily so as not to break the thread or
yarn, and when in line shall descend some distance vertically, before the lower
point of the latch reaches the upper edge of the needle cylinder.
The operation of my improvement will be readily understood from the drawing.
The needle having descended in the needle groove or race, as shown in Fig. 3 to
form the stitch, rises in a vertical line, the front edge from the toe to the top being
just even with the outer edge of the needle groove, in the same manner as the
front or vertical needles, until the part f g of the jack reaches the depression di in
the groove, at which time the lower point of the needle latch will be about a
quarter of an inch above the top of the needle cylinder; as the needle continues to
rise, the upper part of the jack, owing to the tension of the cloth on the needle, is
pulled backward towards the centre of the cylinder and away from the needle cam,
and the inclined surface e. f. of the jack sliding against the inclined surface i. j. of
the needle groove, the needle and jack are drawn back, out of line with the front
or vertical needles, until they assume the position shown in Fig. 2, and the rear
edge e el of the jack rests against the groove and then ascend vertically until the
top of the jack is even with the top of the needle cylinder, when the needle is in
position to receive the weft thread When about to make its stitch, the needle will
first descend vertically, on account of the vertical portions gf and di of the jack
nd groove, till the incline ef comes against the incline i j when the jack and
needle will be thrown forward and into line with the vertical needles, so that the
front edge is even with the outer edge of the needle groove as shown in Fig. 3 in
which position it will descend and complete the stitch.
It is not necessary to provide any mechanism to throw back the needle as it
ascends in the groove, as the tension of the cloth or fabric already knitted, which
always tends to hold the needle back against the needle cylinder, is sufficient to
draw the needle and jack back towards the centre of the machine and in position
to receive the weft thread. I am thus enabled to do away with all presser wheels,
or special mechanism for effecting this object.
On account of the peculiar form of the needle jack and groove the needle is
brought rapidly forward and in line with the vertical needles before it descends to
take the forward thread and form the knitting stitch.
By my improvement I am enabled to use a short and very rigid needle and one
that will knit with great exactness, owing to the absence of spring in the needle itself, .
and am enabled to separate and bring together the two lines of needles in an
effective manner, with little liability of breaking the thread, or of bending or
injuring the needles, and with a minimum of friction and wear of the jacks.
When the needle or needle jack is drawn back as above described, the bottom or
lower end of the jack, or of the needle in machines where no needle jack is
employed, is apt to be thrown outward so as to come in contact with the stationary
cam cylinder, surrounding the needle grooves or races. For the same reason the
upper part of the jack or of the needle is liable to come in contact with, and rub
against, the cam cylinder when it is thrown forward in descending. There is
danger, therefore, of those needles, which have a back and forward motion, coming
in contact with the cam cylinder, and thus injuring the parts, and interfering with
the perfect operation of the machine.
The second part of my invention is intended to prevent this occurrence, and to
provide means which will confine the needles or needle jacks within the grooves
4

page_text: for races, so that they cannot touch, or come in contact with, the cam cylinder, and
yet will have perfect freedom in moving up and down to form the stitch.
The grooves or races in which the needles or needle jacks move up and down,
are formed in the outer face of the revolving, needle cylinder, and, as heretofore
'constructed, are open for their whole length on the side next to the cam cylinder.
In order to hold the needles or jacks within the grooves, therefore, and prevent any
uneven movement of the same as they ascend and descend, the needle cylinder
must be placed very close to the cam cylinder; and great care is necessary to con-
struct and adjust the two cylinders, that the one will turn within the other
without rubbing, and yet fit so closely as to allow very little backward and forward
play or movement of the needles or jacks. In the case of those needles that move
back to receive the weft thread still greater care is required, and it is necessary to
finish the inner face of the cam cylinder with a very smooth and true surface to
reduce the friction and prevent any injury to the machine, if the needles or jacks
should come in contact with the cylinder.
:
:
My improvement consists, essentially, in providing guards on the outside of the
grooves on the needle cylinder, in such positions as to confine the needles or jacks
(within the grooves or races, and at the same time not interfere with the movement
of the toe or crank which is on the needle or jack, within the cam on the cam
.cylinder.
The most convenient method of applying my improved device, is by attaching a
metallic ring or band to the outside of the needle cylinder, so as to surround the
⚫needle grooves or races, as-will be seen at F in Figs. 2, 3 and 4.
These bands, as will be understood from the drawing, are attached to the top
and bottom of the needle cylinder, and in such a position as to be above and below
the highest and lowest position respectively of the crank or toe K on the needle,
as it is moved up and down by the cam G on the cam cylinder A. The bands or
rings, therefore, are so placed as not to interfere with the up and down motion of
the toe in the cam G and at the same time, are in such a position as to prevent the
upper and lower ends of the needle or needle jack from being thrown out of the
groove or race.
These rings or bands may be secured to the needle cylinder in any convenient
manner, as by a screw applied at the point where the ring crosses the bar in the
needle cylinder. As the rings or bands are merely attached on the outside of the
grooves they do not interfere with the free movement of the needles, and as they
revolve with the needle cylinder, there can be no friction or rubbing between the
surface of ring and the needle jack, when they happen to touch each other.
The inner surface of the cam cylinder is cut away, as shown at Q to accommo-
date the projecting ring or band, which may be of any thickness and width found
desirable.
As these rings prevent the edges of the grooves and of the jacks or needles from
touching the cam cylinder, it follows that the only point of contact between the
two cylinders is the surface of the rings and the recessed surface Q of the cain
cylinder, and by constructing these surfaces with care, it is possible to make the
one cylinder revolve within the other with great evenness and smoothness and to
reduce the friction to a small surface. As the rings hold the needles or jacks
within the grooves, the two cylinders need not be placed so close to each other, it
only being necessary to keep the cam cylinder so near to the needles or jacks that
the toe or crank shall always remain in the cam groove. It is, therefore, not
necessary to finish so carefully the whole interior surface of the cam cylinder, and
I am thus enabled to construct the machine at less expense, and more rapidly.
A single ring may be used if desired, either at the top or bottom of the needle
cylinder, as it is found that with the peculiar needle or needle jack employed, only
one, the upper or lower, end of the needle or jack is liable to be thrown out and
come in contact with the cam cylinder.
( Instead of the rings or bands shown and described above, other devices may be
used for carrying out my invention and confining the needles or jacks in their

page_text: grooves; as projections may be formed on the edges of the grooves, and adapted to
be turned over the needles or jacks so as to hold them in place.
By my improvement I not only hold the needle or needle jack in place and
prevent their contact with the stationary cam cylinder to cause injury to the parts
and interfere with the perfect working of the machine, but I am enabled to make
the machine run with greater smoothness and regularity.
The third, part of my invention consists of a novel method of constructing the
cam cylinder which imparts the up and down motion to the needles.
In the Knitting Machines as heretofore constructed, the cam cylinder has been
made in one piece, with a groove or race on the inner surface to engage the cranks
or toes of the needles or needle jacks so as to raise and lower the needles to form the
knitted stitch.
My improvement consists in constructing the cam cylinder in two parts or
sections, one above and one below the cam race or groove, or dividing the cylinder
into two parts by the race or groove which extends through the cylinder from the
inner to the outer faces, as will be understood from Figs. 5 and 6. Heretofore in
forming the groove or cam on the inner face of the cylinder, there has been much
difficulty in getting the groove true and just the right shape to cause the needle
to move evenly; and when once formed it was impossible to alter the groove to
accommodate needles or jacks having larger or smaller toes or cranks.
In my improved construction I form the cylinder in two sections or parts A. A¹
Fig. 5, and make the lower edge a of the upper section, and the upper edge a' of the
lower section of such shape and configuration, that when the sections are put in
position and held apart, as shown, the space G between the sections will form the
groove or cam. It will be seen that this space, and consequently the groove, may
readily be widened or narrowed, by moving the two sections apart or toward each
other, and thus accommodate the toes or cranks of the needles or jacks, and insure
their moving evenly and truly in the grooves. And by connecting the two sections
so that they can be adjusted with respect to each other, the groove may be altered
at pleasure.
The two sections may be held together in any manner found convenient, but
I prefer the method shown in the drawing and described below.
On the outer face of each section, at certain determined points, are lugs or pro-
jections H provided with holes, which in the case of the lower section have inner
screw threads. Passing through the lugs or projections are studs I adapted to
screw into the lugs on the lower section, and provided near their upper end with
shoulders 1 on which the under side of the lugs on the upper section rests. The
top or upper end of the studs which projects above the lug is made of smaller
diameter than the remainder and is provided with a screw thread, over which a
nut h may be screwed tightly down against the upper lugs to hold the two sections
firmly in place after having been properly adjusted. The two parts or sections are
steadied by dowel pins p which are fastened to the lug on the lower section and
pass into holes in the upper section. It will be readily understood that by turning
the studs I one way or the other, and thus screwing them into or out of the lugs
on the lower section, as the upper section rests upon the shoulder on the stud, the
two sections will be brought towards or moved away from each other, and may be
adjusted so as to give the space or race between them any desired width. After
having been adjusted the nut on the upper part of the stud is screwed down against
the lug when the stud will be prevented from turning, and the two parts or sections
of the cylinder be held firmly in position.
When the machine is in operation the needles will rise and fall with reluctance,
owing to the tension of the cloth; for this reason the toes of the needles will always
engage with the face of the cam race or groove opposite to the direction in which
they are moving; that is if the needles are going upward they will be lifted by the
lower face of the cam race, and if coming downward, they will be driven by the
upper face of the cam race. I therefore finish or polish only the faces of the cam
race against which the needle or jack toes engage, but, to prevent any danger of

page_text: :
the toes catching against the unfinished surfaces, by accident, it might be preferable
to make the parts of the cam cylinder with these unfinished and alternate sections
of their faces cut away so as to retreat somewhat from a line parallel to the
opposite and needle actuating surfaces, as shown by dotted lines in Fig. 5.
By my improved method of constructing the cam cylinder in two parts or
sections, I am enabled to vary the width of the race so as to accommodate the
needle cranks, and ensure the needles moving evenly and smoothly, and without
unnecessary friction. And moreover in my improvement I can construct the race
more easily and cheaply and at the same time more perfectly than when the race is
formed by a groove in the inner face of the cylinder.
My stopping device consists of a lever m¹ pivotted at n to a bracket situated on
a ring or part of the frame C which surrounds the needle cylinder and is below the
'cam cylinder. The upper part of the lever terminates in a hook, m³ and the lower end
is connected to a steel rod, n¹, by the pivot n². This rod n¹ slides back and forth
in a hole c¹ in the ring C. In the needle cylinder are a number of holes c'
corresponding in position with the hole c¹ in the outer ring.
Above the pivot n³ and below the pivot n is rigidly fixed a cup, O, of iron or
other suitable metal, of sufficient weight to operate the lever m', by turning the
upper end outward when it is not held in place by the yarn passing through the
hook me at its upper extremity.
For convenience in application I connect two levers m³, in one bracket N, which
is fixed in place by the screw m passing through a slot to make it adjustable,
though, if desired, each lever may be constructed with a separate bracket.
If, from any cause, more weight should be required to operate the stopping
device, the cup O serves as a receptacle for shot or other convenient weighing to
any amount that may be required.
In use the steel rod n³ is inserted in the hole c³ in the ring C, and the hook m³ at
the top of the levers m¹ is made to engage the yarn as it leaves the cross-bar x to
pass to the thread guides. A line of holes c³ are formed in the cylinder B¹ so as
to correspond exactly in size with the holes c¹ in the ring, in which the rods n¹ are
inserted, so that when the yarn is removed from the hook m³ and that end of the
lever m¹ released the weighted cup O forces the rod n' against the surface of the
cylinder B' and into the first hole which comes before it, thus effectually locking
the cylinder to the fixed ring C and stopping the loom instantly before another
stitch can be taken, as hereinafter described.
To avoid jar and strain on the loom when stopped and held by the stopping
device, I arrange the pulleys so that the stopping of the loom unclutches the pulley
automatically and disconnects the power until it is reclutched at the pleasure of the
operator.
For the purpose of taking up and winding in compact form the cloth as fast as
it is made and at the same time giving the proper tension to the cloth at the
needles, I attach to the bottom of the cylinder B¹, by the screw-bolts r, a frame
made of wrought iron, and consisting of two broad bars, R R extending downward
nearly to the floor, then turning at right angles, and meeting at the center R¹,
where they are halved and firmly fixed together by means of screws. By this
manner of construction the whole frame can be taken apart and removed with ease;
or by removing the screw at R¹and loosening one of the bolts r the rollers S and Si
can be removed and replaced without difficulty.
At the lower end of the frame I place two friction-rollers, S and S¹, placed one
above the other, having bearings in the bars R R, and being coated with emery or
otherwise roughened on the surface to cause them to engage the cloth sharply. The
lower roller, S¹, is so arranged in a slotted bearing that by means of the movable
blocks or plates 8 it can be raised or lowered at pleasure and secured in the desired
position by the set-screw 8¹.
To each of the bars R R, I attach an iron plate, T, extending from above the
roller S to nearly half way to the iron rods r¹, and projecting on one side beyond

page_text: the edge of the bar R, and provided with a flange, t, which, with the edge of the
bar R, makes a groove, t¹, which is open at the top.
In the grooves t¹ t¹, I place the ends of a rod, U, constructed of iron or other
heavy material, which is allowed to slide down in the grooves, and is provided with
a boxing on which is rolled the cloth to rest on the top of the roller S and is not
confined vertically above, but is allowed to rise up as the cloth-roll increases, until it
is ready to be removed from the loom, which is done by cutting the cloth and raising
the roll until the ends of the rod U are removed from the tops of the grooves t¹ t¹.
The rod U, except its journaled ends, which turn and slide in the grooves t¹ t¹, may
be made square and boxed with straw-board or other suitable material in such
manner that it cannot turn in the boxing, but can be easily withdrawn endwise
therefrom. The said boxing should be made cylindrical, in order that the web
rolled thereon shall have a cylindrical form and press evenly on the roller S below.
It is used for the purpose of removing the web from the rod when the said web is
large enough to remove from the loom. One end of the journal of the roller S
passes through a hole in the end of the arm J, and then through a bearing in the
bar R, and then through a ratchet-wheel, J, to which it is rigidly fixed, as also to
a crank-wheel, u, on its outer end, which is provided with holes in its outer edge,
into which the hand-lever u¹ may be inserted for the purpose of more easily
tightening the cloth-roll when desired.
To the outer end of the arm J is pivoted a rod, Y, which passes up through a
guide-link, Y, which is firmly riveted to the bar R, and extends upward through
another guide-link, Z, also fixed to the bar R, to a point a little below the lower
side of the table V, where its upper end terminates in a pivoted roller, t. On the
pivot which attaches the rod Y to the arm J is placed a pawl, y, which engages
the ratchet-wheel J¹ on its upper side.
To the bar R, directly over the ratchet-wheel J¹, is pivoted another pawl, z,
which engages the ratchet-wheel on its side opposite to the arm J.
On the rod Y, near its upper end, is placed a collar, y', which can be moved up
or down and fastened with a set-screw, 3. Around the rod Y is placed a helical
spring, T¹, which rests on the guide-link Y¹ at its lower end, being held in place
at its upper end and its tension regulated by the collar y), which is adjustable by
means of the set-screw y². Above the collar y¹ is another adjustable collar, y³,
which, being firmly fixed to the rod Y by its set-screw 3', when forced up by the
action of the spring T¹ impinges on the guide-link Z and limits the portion of
the rod Y which extends above the guide-link Z thereby adjusting the pivoted
wheel t to engage the inclined studs Z¹ at a greater or less distance from their
lower extremity, as may be desired to regulate the action of the pawl y.
On the under side of the table V, at equal distances apart, are placed, in the line
of the pivoted roller t, four studs, Z, with inclined surfaces, against which the
pivoted roller t strikes when the loom is in operation.
A greater or less number of studs Z' Z¹ may be used, according to the size of
the loom, or other controlling circumstances.
If, from any cause, it becomes necessary to tighten the cloth or roll it up more
rapidly than is accomplished automatically, it may be done by inserting the small
lever u¹ into the holes in the periphery of the hand wheel u, or by turning the
hand wheel u with the bands; and it may be loosened in the same manner by
raising the pawls y and z and turning the hand wheel u backward.
When the roll of cloth has become as large as desired it may be cut across
between the roller S and the cloth-roll U (care being taken to leave enough on the
loom to be attached to the bar U,) and removed by simply lifting the bar U out of
the grooves t¹ and pulling it from the center of the roll, when it may be again
replaced in the grooves t¹, with the cut end of the cloth attached to commence a
new roll. Attached to the cam cylinder by means of a set-screw, l, passing through
a slot, is affixed a cloth-presser, L, consisting of a plate of steel so bent as to pass
over, above, and behind the needles, with its free end above the cloth, near the top
of the cylinder B¹, in such position as to prevent the cloth from being forced

page_text: upward by the clinging of the loops to the needles. This cloth-presser is adjustable
by means of the slot at the set-screw l, and the free end may be bent inward, so
as to be as near the needles as desired.
For the purpose of keeping the cloth in proper shape when it leaves the needles
and guiding it to the cloth-roll U, I construct an adjusting cloth-guide consisting
of a ring of iron wire, W, a little less in diameter than the inside of the cylinder B¹,
with a bail-like appendage, w, which I place within the cylinder after the cloth
has been passed down between the rods r17, with the ring W resting on the
cloth below the needles, and the bail-like appendage on or above the rods rol pol
for the purpose of spreading and guiding the cloth on its way to the cloth-roll U.
