MANUFACTURE OF STOCKINGS, AND IN MACHINERY FOR PRODUCING THESE
AND OTHER LOOPED FABRICS."
PROVISIONAL SPECIFICATION left by the said Henry Josiah Griswold at
the Office of the Commissioners of Patents on the 3rd December 1880.

HENRY JOSIAH GRISWOLD, Managing Director of the Company Griswold and
Hainworth (Limited), of Charterhouse Square, in the County of Middlesex.
'IMPROVEMENTS IN THE MANUFACTURE OF STOCKINGS, AND IN MACHINery for
PRODUCING THESE AND OTHER LOOPED FABRICS."
My Invention relates, first, to the manufacture of an improved bed room or
house slipper.
In carrying this part of my Invention into practice I form what is known as a
"niantic" sock, completely fashioned with the well known round heel and toe,
but with the leg shorter than usual, preferably not more than 1½ inches above
the top of the heel. Having drawn upon a last a sock so made I apply to it,
preferably by means of a waterproof cement, a sole of leather, felt, or other suitable
material. An insole may also be fastened inside the slipper, if preferred, and the
sole may be sewn instead of gummed on; for this purpose the well known "Blake
sole sewing machines will be found very suitable. The sock may be embroidered
or knit in strips or fancy patterns, or otherwise ornamented; and it may first be
milled or fitted to the exact shape of the last.
"
According to another part of my Invention I form a stocking for bicyclists' use
with a spring knee-cap, by inserting in the front of the knee of the stocking a
gusset similar to one half of the heel or toe. I also knit upon the stocking one or
perhaps two narrow strips of web a few inches long, upon the end of which I form
a button-hole. These strips being buttoned on to the trousers or waist-band
effectually keep the stocking from slipping down. The spring knee-cap fitting

page_text: perfectly the knee of the rider when in a bent position, removes all strain, and
thus increases the comfort of the wearer and the durability of the hose.
Upon a circular reversible knitting machine I have learned to form the toes in a
manner more expeditious than heretofore, and at the same time equally as well
fitting as those heretofore made; I accomplish this object as follows, viz. :-
After having knit the leg, heel, and foot, I put out of action half of the needles
on one side of the machine, and then narrow the other half by putting out of action
one needle each time across, until, say, six needles remain; I then put the remaining
six needles out of action, and have then completed one half of the toe. To form the
other half I put into action the needles which were out of action at first, and upon
these form the other half of the toe in the same manner as the first. I then put
all the needles into action and knit two or three complete rounds. The toe is then
sewn up by the mending stitch, and this may be so accurately performed as not to
shew the joining.
My said Invention also relates to various improvements in machines to be
employed in the manufacture of the above and other knitted fabrics.
This part of my Invention comprises an improved self-acting needle to be used
in combination with blocks of cams, by which, in a circular knitting machine, I am
able to dispense with the clasp ring heretofore used, and also with that part of the
cam-ring extending above the ledge whereon the butts of the needles are usually
supported when at rest. The butt of my improved needle (that is to say, the
projection on which the actuating cam works) is situated about midway between its
hook and the end of its shank, and the part of the shank below the butt is preferably
waved or curved in opposite directions, so that its edges fit and bear upon the
groove in the needle-cylinder and the cam ring, and the needles thus formed will
be retained in their positions without a clasp-ring even when there are no stitches
upon them.
One set of the aforesaid cams is constructed and arranged as follows, that is to
say-On an adjustable block I fix three or four stationary cams. Two of these cams
are similar in form and situation. In whichever direction the machine is rotated
or reciprocated, the one of these two cams which precedes the other lifts the needles
to free their latches from the loops, while the other cam depresses the needles to
knock off the newly formed loops, that is to say, the cam which when turning to
the right acts as an upthrow cam becomes the knitting cam when turning to the
left. Between the upper ends of these two cams is an inverted cam, the office of
which is, after the needles have been lifted up to clear the loops, to depress them
sufficiently to compel them to engage with the knitting cam which follows the said
inverted cam.
Another cam or rest may advantageously be fixed to the block between the two
knitting cams for the purpose of preventing the dropping of the needles before the
yarn has passed under their hooks.
This block of cams above described may be fastened to an adjustable support
capable of being readily raised or lowered for the purpose of adjusting the length
of the stitch, or the support may be fixed and this adjustment accomplished by
raising or depressing the needle-cylinder.
This block of cams is preferably pivotted to rock or oscillate in such a manner
that the cam which at the time is acting as an upthrow is lower than the one
which is acting as the knitting cam. The needles may all or any of them be
rendered inactive by causing their butts to pass either underneath or over this
block of cams. If this block of cams is not made to rock, two auxiliary or switch
cams will be required to guide the butts of the needles into the proper position to
be actuated by the cams.
Another set of cams to be used in combination with the aforesaid needles is
arranged as follows:-The upthrow-cam has preferably the form of a truncated
triangle, and is preferably fixed rigidly to the cam-ring of the machine. Above
and slightly to the right and left thereof are placed the knitting cams, which are
similar in form and position, but neither of these last mentioned cams will act as

page_text: an upthrow cam; but that which follows the aforesaid upthrow cam, whichever
way the machine may be rotated or reciprocated, acts at the same time as the
knitting cam. I denominate these devices wing-cams.
Although the upthrow-cam is by preference immovably fixed to the cam-ring,
the two wing-cams are fastened to a block and may be arranged to move up and
down for the purpose of adjusting the length of the stitch, or they may be made
unadjustable and the needle cylinder be made to rise or fall for this purpose.
A space is preferably left between the two wing-cams, so that a needle may at any
time, when required, be raised out of or put into action at the instant before it is
depressed to form the stitch. Both of these blocks of cams may be attached to the
movable cam-ring, or they may be fixed to the stationary part of the machine, the
needle-cylinder being in this case made to revolve or reciprocate.
When I use either of these sets of cams the "automatic" reversing gear described
in the Specification of my former Letters Patent, dated Aug. 21st, A.D. 1872,
No. 2489, may be dispensed with.
I am able to produce a cheap circular knitting machine suitable for domestic
use by making the body of the machine, the clamp for fastening the machine to
the table, and the cam-ring all in one piece. The needle-cylinder has on its lower'
edge bevel-teeth which gear with a bevel-wheel supported by the body of the
machine and actuated by a crank-handle. In this machine the needle-cylinder
may be rotated or reciprocated at will.
To the stationary cam ring I may fix a block of cams similar to either of those
above specified, in such a manner that they may be raised or depressed in respect
to the needle-cylinder to make a longer or shorter stitch. To the body of the
machine or to the cam-block is rigidly fixed a yarn-guide, in such a position as to
supply the yarn to the needles as they descend to form the stitches. The cams do
not extend as high as the top of the cylinder, so that the needles can be lifted out
of action to narrow and widen, as, for instance, in forming the heel and toe of a
stocking.
The machine, as above described, is for knitting only a plain web, either flat or
tubular, which may be widened or narrowed at will. When the machine is
required to knit a ribbed web I supply it with a ribbing attachment preferably
constructed as follows:-
To the body of the machine is rigidly fixed a curved arm having a boss for a
journal parallel with the axis of the machine, and having a hole bored through this
boss exactly concentric with this axis; a bolt or spindle passing through this hole
supports the ribbing dial and the cam-caps of the ribbing attachment, both of
which turn freely upon the spindle. On the bottom of the dial are one or more
lugs which engage with corresponding lugs on the inside of the needle cylinder so
that when the latter revolves the former must revolve with it. When the ribbing
attachment is required to act, the cam-cap is held stationary by a pin or otherwise
with the ribbing arm and not allowed to revolve, but when the ribbing attachment
is not required to knit, as, for instance, while forming the heel or toe of a stocking,
the cam-cap is allowed to revolve with the dial.
This ribbing attachment may be readily removed when the machine is to knit a
plain web only.
"
My Invention also comprises two straight needle-beds parallel to each other with
their tops just sufficiently separated to allow the knitted web to pass easily down
between them. I prefer that the needles in this case should work vertically, but the
beds may be so inclined toward each other that the needles will cross each other,
s in the well known "Lamb knitting machine. Instead of the needle-bed
tself being grooved, as usual, I supply a series of grooved quills, preferably of
empered steel; these quills are arranged on the outside of each of the needle-beds,
and are held in their places by means of bars and levers, or in any other convenient
r suitable manner.
When provided with these last described parts, my machine is very useful for the
manufacture of Scotch bonnets as well as stockings or other hosiery.

page_text: The said quills may be removed from one part of the machine and inserted in
some other part, so that the narrowings and widenings are not confined to the
selvedge or any particular portion of the web, but may take place at any point
desired, and it may be seen that my Invention is equally applicable to a circular
machine or to a flat machine with either one or two rows of needles.
My Invention also comprises an improved set-up or device for starting the work
automatically. This is constructed of a series of wires whose number is equal to
that of the needles in the machine. Each wire is curved, and terminates at one end
with a hook and at the other end with a loop, and is considerably longer than the
radius of the needle cylinder of the said machine. When used in a circular knitter
the looped ends of the said device are fastened to a supporting ring with freedom
A disc about double
of movement like the upper ends of the ribs of an umbrella.
the size of the hinged support has holes near its outer circumference, and each one
of the wires passes through one of these holes. The said disc is so combined with
the said wires that when it is pressed upwards the said device will be contracted
or closed, and when the disc is depressed the said device will be expanded or
opened like an umbrella; mechanism is provided for raising and depressing the disc
and a ring to which a weight may be attached. In applying this automatic "set
up" to my improved knitting machine, I apply the "set up " to the top of the cylinder,
having expanded it so that its hooks project outside the hooks of the needles. I
then, by means of the yarn-carrier of the machine or otherwise, pass a yarn under
the hook of each needle, then I hang on the "set up "the weight, which so contracts
it as to bring the hooks within the cylinder, the said device being suspended by its
hooks from the yarn; I then proceed with the knitting.
•
This improved "set up "is also applicable to my machine when the same is adapted
for knitting Scotch bonnets as above specified, but the wires are then placed in two
straight rows instead of in a circle, and it is equally useful for setting up only part
of the set of needles for the purpose of knitting a flat web.
Another part of my Invention relates to a convenient method of stopping
knitting machines when a certain required length of web has been knit, and is
applicable to other machines for like purposes.
For this purpose I place upon the driving spindle a fast and a loose pulley and
arrange a lever with a fork for shifting the band from one pulley to the other. This
forked lever has a spring so adjusted that the band runs normally on the loose
pulley, but when the forked lever is drawn over so as to throw the band on to the
tight pulley it is caught and held there by a trigger. In connection with this
trigger a wire rod extends perpendicularly nearly to the floor, the weight of the
said rod being counterbalanced by a weighted lever or a spring.
On this wire are secured brackets which may be adjusted perpendicularly
according to the length of the web to be knitted, and either one of these brackets
may at will be brought under the weight as descends. The said brackets are so
adjusted on the wire that one of them will be touched by the weight as soon as
the ribbed top of the stocking is finished, another as soon as the leg has been
knitted, a third when the ankle has been completed, and the fourth when the foot
is finished.
Another part of my Invention relates to means for automatically counting the
rows of stitches made by the said machine. To effect this object I employ a
graduated dial with teeth or notches on the outside, a reciprocating lever carrying
a pawl, a spring for holding the pawl in action with the toothed dial, another
spring for keeping the dial from turning more than one tooth at a time, a cam
preferably attached to the reversing ring of the machine, a spring for keeping the
reciprocating lever back except when pushed forward by the cain and a pointer
The pointer of this device having been set at zero, at each revolution or reciproca
tion of the machine the said lever is pushed forward, causing by means of the paw
the dial to revolve one tooth at a time. It is kept from returning by another
spring. The pointer always indicates the number of rows that have been knitted
whether of flat or tubular web.

page_text: I modify my Invention in the case of machines which knot a circular web and
which revolve only in one direction by providing an improved indicator, which will
record the number of revolutions continuously, and is at the same time very
compact and but little liable to disarrangement.
It is not only applicable to knitting machines but will record the number of
revolutions of sewing or other machinery, and may with obvious slight modifica-
tions be used for causing the machine to change automatically from knitting
tubular to knitting flat work, and vice versa, and for making other periodical
changes. The said indicator is constructed as follows:-
A ring provided internally with teeth has a disc fastened to one side. Instead
of this toothed ring is a spur gear-wheel slightly smaller in diameter and having,
say, one tooth less than the said ring. The spur gear-wheel is kept in gear with
the ring by means of an excentric which makes the same number of revolutions as .
the machine. If the toothed ring has 100 teeth and the spur wheel 99 teeth and
the latter is kept from revolving, the internally geared ring will revolve once while
the machine and excentric make 100 revolutions.
To this first toothed ring I may fix a second excentric carrying a spur gear
wheel and geared with a second internally-toothed ring. If the additional spur
wheel and ring have respectively 99 and 100 teeth the second ring will make one
revolution while the machine is making ten thousand revolutions. Other series of
toothed gearing may be added if required, and this simple contrivance may be made
to record continuously the number of revolutions of the driving wheels of a
locomotive or other engine.
The periphery of each of the internally toothed rings may be graduated so that
at a glance the number of revolutions may be read thereon.
In applying my said Invention to knitting machinery I use preferably only one
series of the said gearing, and place on the side of the ring a graduated disc which
may be rotated and adjusted in respect to the said ring to be set at zero at the
commencement of each article. Either on the last named graduated disc or on the
internally toothed ring I may fix a cam or projection which will either ring a bell
or push a trigger to stop the machine when a determined number of rows has been
knit.
Another part of my Invention relates to means for automatically knitting ribbed
tops or cuffs. For this purpose I fix above the dial and cam-cap of my knitting
machine constructed for knitting a 1 and 1 ribbed web, an excentric toothed ring
and spur wheel as above described. If, for instance, the ribbed tops are required
to have 60 rows each I construct the toothed ring with 60 and the spur wheel with
59 teeth.
The cam-cap of the ribbing attachment has the out-throw cam so constructed
that it may be thrown into and out of action by cams fixed to the internally
toothed ring. The knitting cam of the knitting machine is also so constructed
that the stitch may be lengthened or shortened by means of a series of levers
actuated at intervals by cams fixed to the said ring. This machine will auto-
matically knit the ribbed tops of a predetermined length so long as it is supplied
with yarn.
Another part of my Invention relates to a bobbin-stand for a knitting machine.
I construct this stand of a disc supported upon feet. From the centre of the disc
there extends upwards a tube of small diameter. The bobbin is preferably made
of tin and of the shape of an ordinary reel for sewing-cotton. Through the centre
is a hole to fit the said tube on which it turns as an axle, and on one end thereof
is a handle by which the bobbin may be revolved. To fill it with yarn I have
only to revolve the bobbin by means of the said handle while it rests upon its
stand. When knitting the yarn is passed over the top and down through the
tube, emerging under the bobbin-stand, and is readily unwound from the top of
the bobbin without revolving the latter.
Another part of my Invention relates to providing an ordinary circular reversible
knitting machine (so constructed that the needles may be put out of action for

page_text: shaping the heel and toe of stockings), with one or more auxiliary sets of cams
which may be put into action only when knitting the tubular part of the stocking
for the purpose of accelerating the work or for knitting stripes or alternate rows
of different colored yarns.
My Specification, dated 8th October, A.D. 1873, No. 3257, comprises an Invention
for adjusting the needle-frame of the ribbing attachment and the needle frame of
the knitting machine to each other, so that the ribbing needles may be set at the
will of the operator either over the posts or over the grooves of the needle-cylinder
to allow of shaping the leg of a stocking by narrowing one stitch at each rib
gradually down the leg, and in the said Specification I have illustrated and
described one method by which such adjustment may be accomplished. I will
now describe other methods by which the same result may be attained.
In my improved knitting machine, in which the needle-cylinder revolves as
described under the 4th heading of this Specification, the dial of the ribbing
attachment is made to revolve simultaneously with the cam-cylinder by means of
a lug or lugs on the said dial which engage with a lug or lugs on the inside of the
said cylinder. In order to adjust the said cylinder and dials to each other
according to my present Invention I make the lugs of the said cylinder
movable preferably by attaching them to a ring fitted to the inside of the cylinder,
which ring with its ribs is adjustable in respect to the said cylinder by means of a
screw or otherwise, and may be retained in any desired position. I may make the
lug on the inside of the cylinder detached, and extending the whole depth of the
inside of the cylinder. This detached lug or lever I may pivot in the centre, and
arrange its lower end to be adjusted by means of a screw or otherwise.
obvious that in adjusting the said lower end of the lug I should also adjust its
upper end which is in combination with the fixed lug on the dial or ribbing needle-
frame.
It is
Or I may use a detached lug or lever on the bottom of the dial in combination
with a fixed lug inside of the needle-cylinder. This lever is preferably pivotted at
the centre and to the spindle, in which the dial and cam-cap are supported.
make this lever adjustable to the dial preferably as follows, that is to say:-
I
A bolt with a large head has placed upon it first the aforesaid lever, then the dial,
then a tube, all fitted neatly to the said bolt. On the upper end of the said bolt
is a screw with a nut; when this nut is screwed down tightly these parts, viz., the
lever, the dial, and the tube, will be held rigidly together as if they were made in
one piece. By loosening the nut however the dial may be adjusted in relation to
the lever, and then held in its altered position by again tightening the nut. The
said tube passes up through the cam-cap and the boss of the ribbing arm, both of
which revolve readily around it, and the nut which adjusts the dial to the lever
may also hold all these parts suspended from the ribbing arm.
Heretofore in circular knitting machines in which the needle cylinder is
stationary and the cam ring revolves I have made the dial adjustable to the
cylinder which is stationary. I have found however that under certain
circumstances it is more convenient to have the dial fixed and the cylinder
adjustable, so that the latter may be moved gradually either to the right or to the
left. In such a case I make the dial or ribbing needle-frame fixed to the arm that
supports it, and the said dial is kept from revolving by means of a feather or set
screw. The needle-cylinder of the machine is made adjustable by means of a
screw or otherwise.
All of these devices for adjusting the cylinder and dial or ribbing frame to each
other have been suggested by experience; under some circumstances I prefer one,
under other circumstances another; but 1 consider each of such devices as only
modifications of the general principle of adjusting the cylinder and ribbing frame
of a reversible circular knitting machine to each other as set forth in my said
former Specification.
To a circular reversible knitting machine of the usual type I have added certain
improvements by which I am able to knit, in addition to the usual work done on

page_text: such machines, also a tubular web of any diameter and narrow or widen such web
at will.
I arrange this machine so that when the needles are at rest their hooks project
only slightly above the cylinder, and so that the upthrow cams may be put out of
action. I supply the machine with a ribbing attachment having a dial cut with
the same number of grooves as the cylinder of the machine and cams so arranged
that it will knit only when turned to the right, while the machine may be so
adjusted as to knit only when turned to the left.
This machine without the ribbing attachment is capable of knitting a tubular
web of a fixed diameter according to the size of the cylinder. Upon it one can
also knit a flat web of any width up to the whole circumference of the cylinder,
and narrow and widen such flat web at will, and even change from flat to tubular
work, and vice versa, while the heels and toes of stockings may be perfectly
narrowed and shaped,
When this machine is supplied with a ribbing attachment a ribbed stocking can
also be knitted upon it.
With my improvements however a plain tubular web can be made from the size
of a glove-finger to nearly double the circumference of the cylinder, and be narrowed
and widened at will.

the said Henry Josiah Griswold in the Great Seal Patent Office on the
3rd June 1881.
HENRY JOSIAH GRISWOLD, Managing Director of the Company Griswold and
Hainworth (Limited) of Charterhouse Square, in the County of Middlesex.
"IMPROVEMENTS IN THE MANUFACTURE OF STOCKINGS, AND IN MACHINERY FOR
PRODUCING THESE AND OTHER LOOPED FABRICS."
My Invention relates, first, to the manufacture of a peculiar kind of sock
which may be used a bed-room or house slipper or adapted to serve as a bathing
shoe.
In carrying this part of my Invention into practice I make what is known as a
"niantic" sock, completely fashioned with the well known round heel and toe, but
with the leg shorter than usual, preferably not more than 1/2 inches above the top
of the heel. Having drawn upon a last a sock so made I apply to it, preferably by
means of a waterproof cement, a sole of leather, felt, or other suitable material.
An insole may also be fastened inside the sock if preferred, and the sole may be
sewn instead of cemented on. For this purpose the well known "Blake" sole sewing
machine will be found very suitable. The sock may be embroidered or knit in
stripes of fancy patterns or otherwise ornamented, and it may first be milled and
fitted to the exact shape of the last.
According to another part of my Invention, illustrated in side view in Figure 1
of the Drawings, I form a stocking for the use of velocipede-riders, which stocking
will not wrinkle and bulge at the knee when the wearer is standing, and will not
be subject to injury by stretching at the knee when the leg is bent as in propelling
a bicycle or other velocipede. For this purpose I knit the portion a of the stocking
above the knee at an angle to the lower portion a¹, so that the part a will assume
either of the positions shewn in dotted lines at 1 or 2 with less strain upon the
material of which the stocking is formed than would result from bending to the
position 2 a stocking woven or knitted in the ordinary manner with the part above
the knee in the position 1. For this purpose I knit at the knee of the said stocking
a spring knee-cap or gusset a² similar in shape to one half of the toe of a "niantic"
sock. I also knit upon the stocking one or in some cases two narrow strips a³ a
few inches long, in the end of which I form a button-hole, as shewn. These strips
being buttoned on to the trousers or waist-band effectually prevent the slipping
down of the stocking, and the spring knee-cap fitting perfectly the knee of the
rider when in a bent position prevents the straining of the straps and buttons,
and thus increases the comfort of the wearer and the durability of the hose.
My said Invention also relates to various improvements in machines to be
employed in the manufacture of the above and other knitted fabrics, which
improvements I will now proceed to describe,-
Figure 2 is a plan of one form of my improved knitting machine with the bobbin
stand removed; and
Figure 3 is a front view of the same.
Figure 4 is a vertical central section of the said machine on the line x, x,

Figure 5 is a view of the inner side of the block of cams shewn in Figure 3.
Figure 6 is an underside view of the cams of the ribbing attachment.
Figure 7 is an inside view; and
Figure 8 an edge view of a modified arrangement of the upthrow and knitting
cams hereinafter described.
Figure 9 is an elevation partly in central vertical section of a modified form of the

page_text: devices shewn in Figure 4, for varying the relative positions of the needle-cylinder
and the dial of the ribbing attachment.
Figure 10 is an elevation of the said machine supported upon a standard, which
is provided with means hereinafter described for shifting the driving belt, and
automatically stopping the machine when a certain required length of web has
been knit, the belt or band in this view being shown upon the fast pulley.
Figure 11 is an elevation of the said standard showing the band on the loose
pulley, and
Figure 12 is an elevation of the same on a plane at right angles to that of
Figure 11.
The remaining Figures are hereinafter described.
b represents the bed of the knitting machine which supports the needle-cylinder c,
and on which revolves the cam ring d; fis the dial of the ribbing attachment,
and g is the cam-cap provided with the cams g¹, 92, g³, for operating the needles in
the same; h is the arm for supporting the said ribbing attachment; i is the
block which carries the knitting cams i¹, i, for operating the needles c¹ in the
cylinder c.
The arrangement of the said cams and of the upthrow-cam d¹ is as follows,
that is to say-The said upthrow-cam has the form of a truncated triangle, and is
preferably fixed rigidly to or forms a part of the cam-ring d of the machine.
Above and slightly to the right and left of this cam d' are placed the knitting
cams i¹, i¹, forined and arranged as shewn most clearly in Figure 5 of the Drawings.
Neither of these cams i¹, i, will act as an upthrow-cam, but that one of them
which follows the upthrow cam d' whichever way the cam ring may be rotated or
reciprocated acts as the knitting cam. I denominate these devices wing-cams.
When the upthrow cam d¹ is immovably fixed to the cam-ring d, as above
described, the block i carrying the wing-cams i¹ is preferably so arranged that it may
be moved up and down within a guide-piece i* on the cam ring d, for the purpose
of adjusting the length of the stitch; a space 0 is left between the two wing
cams ', as shewn in Figure 5, so that any one or more of the needles having been
raised out of action may be put into action again at the instant before being
depressed by the knitting cain, and after the yarn has passed under the hook or
hooks of the same.
Instead of attaching the upthrow-cam to the cam-ring d, as above described, I in.
some cases construct and arrange e said upthrow-cam and the knitting cams in
the manner shewn in Figures 7 and 8 of the Drawings, that is to say, on the
adjustable and pivoted block i I fix three or four stationary cams. Two of these
cams 2, 3, are formed and arranged, as shewn in Figure 7, so that in whichever
direction the machine is rotated or reciprocated, the one of these two cams which
precedes the other will lift the needles to free their latches from the loops, while
the other cam will depress the needles to knock off the newly formed loops, that is
to say, the cam 2, which when turning to the right acts as an upthrow-cam
becomes the knitting cam when turning to the left. Between these two cams and
at the upper part of the block i is an inverted cam 13, which is preferably pivotted,
as shewn, and which after the needles have been lifted to clear the loops serves to
depress them sufficiently to compel them to engage with the knitting cam ² which
follows the said inverted cam.
Another part of this set of cams is a rest i which may advantageously be fixed
to the block between the two knitting cams 2, for the purpose of preventing the
dropping of the needles when empty, and before the yarn has passed under their
hooks.
25
This block of cams may be fastened to a support capable of being readily
raised or lowered by means of a thumb-screw 2, as shewn, for the purpose of
adjusting or varying the length of the stitch; or the support may be fixed, and
this adjustment accomplished by raising or depressing the needle-cylinder, and to
prevent any possibility of the dropping of the needles below the lower point of the
cam 2, which is acting as the upthrow-cam. This block of cams is preferably

page_text: pivotted at in such a manner that it will rock or oscillate freely by the action
of the needles thereon, and the cam 2, which at the time is acting as the upthrow-
cam, is thus set lower than the one which is acting as the knitting cam, as shewn
in Figure 7. The needles may all or any of them be rendered inactive by causing
their butts to pass over this block of cams.
Either of the blocks of cams above described may be attached to the movable
cam-ring, or either of them may be fixed to the stationary part of the machine, the
needle-cylinder being in this case made to revolve or reciprocate. In the latter
case I may fix to the stationary cam-ring a block of cams similar to either of
those above specified in such a manner that they may be raised or depressed
relatively to the needle-cylinder to make a longer or shorter stitch. To the body
of the machine or to the cam-block is rigidly fixed a yarn-guide 28 in such a
position as to conveniently supply the yarn to the needles as they descend to form
the stitches in whichever direction the machine is rotated or reciprocated. The
cams do not extend as high as the top of the grooves in the cylinder, so that the
needles can be put out of and into action to narrow and widen, as for instance in
forming the heel and toe of a stocking.
When I use either of these sets of cams the automatic reversing gear described in
the Specification of my former Letters Patent, dated August 21st, A.D. 1872,
No. 2489, may be dispensed with.
In combination with my improved cam-carrying blocks above described I employ
an improved self-acting needle, which is clearly shewn in Figure 4, and in
Figure 4, by which in a circular knitting machine I am able to dispense with
the clasp ring heretofore used, and also with that part of the cam-ring extending
above the ledge whereon the butts of the needles are usually supported when at
rest. The butt c² of my improved needle, that is to say, the projection on which
the actuating cams work, is situated about midway between its hook and the end
of its shank, and the part c³ of the shank below the said butt is preferably waved
or curved as shewn, so that its edges fit and bear upon the back of the groove in
the needle-cylinder and against the cam-ring; the needles thus formed will be
retained in their positions without a clasp-ring even when there are no stitches
upon them.
I will now proceed to describe my improvements relating to the stopping of
knitting machines when a certain required length of web has been knit. In carrying
this part of my Invention (which is illustrated in Figures 10 to 12 of the Drawings)
into practice I fix upon the driving spindle j a bevel-wheel j*, which gears with the
toothed lower part d* of the cam-ring d; I also place on this spindle a loose and a
fast pulley, as shewn at j' and j2, and I may pivot to the standard k supporting
the machine a lever having a fork or loop for shifting the band from one pulley to
the other. I prefer however to use a slide k³, which has a loop k*, or fork, and
which is forced forward by a spring 2, so that the band runs normally on the
loose pulley j¹. This slide is provided at its forward end with a shoulder at k³,
with which a tooth or projection 1, on a pivotted trigger engages when the slide
is pushed back; this trigger has attached to it a small rod 2, which extends per-
pendicularly nearly to the floor on which the machine stands; 1³ represents a
weighted lever, which not only serves to counterbalance this rod but also tends to
constantly raise the same, and consequently force the trigger into engagement
with the slide k¹. On the aforesaid rod 12 are secured brackets *, which may be
adjusted perpendicularly according to the length of the web to be knitted, and
either one of which may by lateral adjustment at will be brought under the weight
attached to the web, and as soon as the weight in descending acts on the said
bracket it depresses the rod 12 and trigger 7, thereby releasing the slide, which is
immediately forced forward by the spring and shifts the belt to the loose pulley,
and stops the machine. The said brackets * are to be so adjusted on the rod 12
that the first or upper one of them will receive and be acted on by the weight as
soon as the ribbed top of the stocking is finished, the second, as soon as the leg has
been knitted, and the third when the foot is finished. The said rod may however

page_text: be provided with any desired number of these brackets *, those that are not being
used during any particular operation being turned or adjusted to one side. I
provide means for drawing back the slide k₁ after the same has been forced forward
by the spring k², and for conveniently stopping the machine in case of accident as
follows, that is to say:-I employ a lever m, which is pivotted at m³, and is
provided with a slot m², through which a pin k projects from the said slide.
This lever has an arm, whose extremity m³ is bevelled and arranged to act as a
cam upon the pin of the trigger when the said lever is pushed forward. The
slot allows the lever to first move sufficiently to depress the trigger before it
acts on the pin 4, and then by acting on the said pin the lever drives the
slide forward. When this lever is drawn back the re-engagement of the trigger
with the bevelled end of the arm m³ is effected automatically by the rising of
the said trigger.
In the Specification of my former Letters Patent, dated October 8th A.D. 1873,
No. 3257, I have described means for adjusting the needle-frame of the ribbing
attachment and the needle-frame of the knitting machine with regard to each
other, so that the ribbing needles may be set at the will of the operator, either
over the posts or over the grooves of the needle-cylinder to allow of shaping the
leg of a stocking by narrowing one stitch at each rib gradually down the leg, and
in the said Specification I have illustrated and described a device by which such
adjustment may be accomplished. I will now describe various modifications
by which the same result may be attained. The dial of the ribbing attachment
may be adjusted with regard to the cam-cylinder by means of a lug or lugs on the
said dial, arranged to engage with a lug or lugs on the inside of the said cylinder.
In order to adjust the said cylinder and dial to each other, according to my present
Invention, I in some cases attach a lug or arm f¹, or a pair of such arms, to the
bottom of the dial in combination with a lug or lugs co cast on or otherwise fixed
to the inside of the needle-cylinder c. I prefer that the said arm or arms f¹ should
be pivotted at the centre to the spindle on which the dial and cam-cap are supported,
and I make the said arm or arms adjustable with regard to the dial f preferably as
follows, and as illustrated in Figure 9 of the Drawings, that is to say:-A bolt f*
has placed upon it the aforesaid arm or arms f¹, the dial f, and the tube ƒ³,
fitted neatly to the said bolt. The upper end of this bolt is screw-threaded for
the reception of a nut f³, which when screwed down holds and clamps tightly
together these three parts, viz., the arm or arms f¹, the dial f, and the tube f2, as
if they were made in one piece. By loosening the nut f3 however the said dial may
be adjusted in relation to the arm or arms f, and then held in its altered position
by again tightening the said nut. The tube f2 passes up through the cam-cap g and
the boss of the ribbing arm h, both of which revolve readily around it. The nut ƒ³,
which permits the adjustment the dial to the arm or arms, may also hold all of
these parts suspended from the ribbing arm.
all
I further modify this part of my Invention, as illustrated in Figure 4 of the
Drawings, that is to say, instead of employing the tube f2 as above described, I
dispense with the same, and form a left-handed screw-thread upon the lower end
of the bolt f* instead of upon the upper end thereof. I also make the arms f'
separate from the said bolt, so that when it is desired to adjust the needle frame of
the ribbing attachment relatively to the needle-cylinder all that is necessary is to
unscrew the boss carrying the said arms, and to turn the needle-frame of the
ribbing attachment into the desired position, when by again screwing up the said
boss and arms the parts will be retained in such position.
In another modification I make the lugs of the said cylinder movable, preferably
by forming them on or attaching them to a ring c, as shewn in central section in
Figure 13 of the Drawings. This ring is fitted to the inside of the cylinder c, and
with its ribs c is adjustable in respect to the said cylinder by means of a thumb-
screw c', which passes through an elongated slot in the said ring c³, and screws into
the body of the cylinder c, whereby the said ring may be retained in any desired
position; or I may substitute for the said screw and slot any other convenient

page_text: device for adjusting and holding the said ring. I may moreover make the lug
on the inside of the cylinder detached, and extending the whole depth of the
inside of the cylinder. This detached lug or lever I may pivot in the centre,
and arrange its lower end to be adjusted by means of a screw or otherwise. It is
obvious that in adjusting the said lower end of the lug I also adjust its upper end,
which is arranged in combination with the fixed lug on the dial or ribbing needle-
frame.
.
Heretofore in circular knitting machines in which the needle-cylinder is
stationary and the cam ring revolves, I have made the dial adjustable relatively
to the cylinder, which is stationary. I have found however that under certain
circumstances it is more convenient to have the dial fixed, and the cylinder
adjustable, so that the latter may be moved gradually either to the right or the
left. In such a case I fix the dial or ribbing needle frame to some stationary
portion of the machine, and the said dial is kept from revolving by means of a
feather or set-screw. The needle-cylinder of the machine is made adjustable with
regard to the body of the machine to which the arm of the ribbing attachment is
rigidly fixed by means of a screw or otherwise.
All of these devices for adjusting the cylinder and dial or ribbing frame to each
other have been suggested by experience. Under some circumstances I prefer one,
under other circumstances another, but I consider such devices as only modifications
of the general principle of adjusting the cylinder and ribbing frame of a reversible
circular knitting machine to each other, as set forth in the Specification of my said
former Letters Patent.
I will now proceed to describe my improved apparatus for automatically counting
the rows of stitches made by the said machine. To effect this object I employ the
apparatus shewn in Figure 2 of the Drawings. In this apparatus there is a
graduated dial n having teeth or notches upon its periphery and journalled, as
sbewn. In combination with this dial I arrange a reciprocating slide n¹ which
carries a pawl n³ forced into contact with the said dial by a spring n³. The
backward movement of the said dial is prevented by a spring n¹; n³ represents
a cam preferably attached to the reversing ring of the machine, and adapted at
each revolution of the cam-ring to force the slide n¹ outward so as to rotate the
dial na distance equal to one tooth, the said slide being drawn back after being
operated upon by the said cam by a spiral or other suitable spring. In some cases
the pawl n² may serve as the pointer, but I may provide a separate pointer or
index if desired. In commencing the work the dial is so adjusted that the pointer
points to zero, and at each revolution or reciprocation of the machine the said slide
is pushed outward, thereby causing, by means of the pawl n2, the dial n to turn
on its axis a distance equal to one tooth. The pointer always indicates the number
of rows that have been knitted of either a flat or tubular web.
I will now proceed to describe my improvements illustrated in Figures 14 to 17
of the Drawings, in which,-
Figure 14 is a plan with the yarn-carrier removed of a knitting machine having
two straight needle-beds as constructed according to my Invention, and
Figure 15 is a side elevation of the said machine.
Figure 16 is a transverse section of the said machine on the line y, y, Figure 15.
Figure 17 is a plan of the said yarn-carrier detached.
In these Figures o, o, represent the two straight needle-beds, which are parallel
to each other, and have their upper edges just sufficiently separated to allow the
knitted web to pass easily down between them through the space o*. I prefer
that the beds should be parallel to each other so that the needles will work
vertically; but the beds may be so inclined that the needles will cross each other,
as in the well known "Lamb" knitting machine. Instead of having the needle-
beds grooved, as heretofore, I provide the same with a series of grooved quills p
preferably of tempered steel; these quills are arranged on the outside of each of
the needle beds o, and are held in their places by means of bars or plates q and the
wedge qº, or in any other convenient and suitable manner; q', q', represent the cam-

page_text: carriers of the said machine, which are free to slide upon rods or bars q² arranged
on each side of the machine, as shewn. These cam-carriers are each provided with
an upthrow-cam q³ and with a knitting cam 9, which is preferably made adjustable
vertically to permit the length of the stitches to be varied.
The said cam-carriers are connected by a curved or U-shaped bar q*, and are
preferably operated by means of a suitable handle attached to one of the said cam-
carriers, as shewn; represents the yarn-guide of the said machine, which is free.
to slide in a diagonal slot in a plate rattached to the U-shaped bar q*. In
combination with this yarn carrier I arrange upon the body of the machine and
near the ends of the same fixed stops when the yarn-carrier has supplied the
whole of one row of needles on one side of the machine with yarn, one of these
stops comes in contact with the said yarn-carrier, and causes it to move trans-
versely in the slot ?* so as to be in the proper position to supply yarn to the
opposite row of needles during the return movement of the cam-carriers. This
operation takes place at the termination of each reciprocation of the machine.
A machine thus constructed is very useful for the manufacture of Scotch bonnets
as well as stockings or other hosiery.
The quills p may be removed from one part of the machine and inserted in some
other part of the same, so that the narrowings and widenings are not confined to
the selvedge or any particular portion of the web, but may take place at any part
desired; and it will be readily understood that this part of my Invention is equally
applicable to a machine with either one or two rows of needles.
I will now proceed to describe an improved set-up device for starting the work
upon a knitting machine automatically. This device is illustrated in Figures 18,
19, and 20 of the Drawings, in which,
Figure 18 is a plan of the said device when expanded, and
Figure 19 is an elevation partly in central vertical section of the same.
Figure 20 is an elevation of the said device when closed. The said set-up
device is constructed of a series of bars s (either flat or otherwise), whose number
is equal to that of the needles in the machine. Each bar is curved, and terminates
at one end in a hook s¹, and at the other end with a loop.
When used in a circular knitter the inner ends of the said device are jointed to
a supporting ring 82, with freedom of movement like the upper ends of the ribs of
an umbrella. A disc 3 nearly double the size of the supporting ring s² has slots
or holes near its outer circumference, and each one of the bars s passes through one
of these holes. The said disc 3 is so combined with the bars that it is capable of
sliding up and down thereon. When it is pressed upwards the said device will
be contracted or closed, as shewn in Figure 20, and when the said disc is depressed
the said device will be expanded or opened like an umbrella, as shewn in Figure 19.
To effect this opening and closing of the device I connect to the disc s³ a rod 8,
secured at its lower end to a plate 85. This plate is free to slide upon the rods or
bars 86, to whose lower end 87 a weight may be attached. In using this improved
expanding set-up device with my improved knitting machine, place the said
device on the top of the needle cylinder, having first expanded it so that its hooks
project outside the hooks of the needles. I then, by means of the yarn-carrier of
the machine or otherwise, pass a yarn under the hook of each needle; then I
suspend from the set-up device a weight, which so contracts it as to bring the
hooks within the cylinder, the said device being suspended by its hooks, and the
yarn from the needles. I then proceed with the knitting. My improved device is
equally useful for setting up in the ordinary manner, and for setting up only part
of the set of needles for the purpose of knitting a flat web.
I will now proceed to describe my improved form of indicator, which will record
the number of revolutions of any part of a knitting machine with which it is
connected, and which may with slight modifications be used for causing the
machine to change automatically from knitting tubular to knitting flat work, and

page_text: vice versa, and for making other periodical changes. This indicator is illustrated
in Figures 21 and 22 of the Drawings, in which
Figure 21 is a plan or top view of the said indicator, and
Figure 22 is a central vertical section of the same, arranged in combination with
the cam-carrying disc of the ribbing attachment and other parts hereinafter
described.
The said indicator is constructed as follows, that is to say:-A ring t provided
internally with teeth has a disc t¹ fastened to it, preferably on its underside.
Inside of this toothed ring t is a spur gear-wheel u having fewer teeth (say, one
less) than the ring t. This spur-wheel u is kept in gear with the ring t by means
of an excentric u', which makes the same number of revolutions as the machine.
If the toothed ring t has 100 teeth and the spur wheel u 99 teeth, and the latter
is kept from revolving by any means (say by an arm fo fixed to the spindle f*,
and passing between projections u* on the said wheel), the internally-geared ring t
will revolve once while the rotating part of the machine and the excentric make
100 revolutions.
To this first toothed ring t I may fix a second excentric carrying a second spur
wheel, and geared with a second internally toothed ring. If this additional spur-
wheel and ring have respectively 99 and 100 teeth, the second ring will make one
revolution while the rotating part of the machine is making ten thousand
revolutions. Other series of toothed gearing may be added if required.
The periphery of each of the internally-toothed rings may have a graduated
scale in combination with the index or pointer, so that at a glance the number of
revolutions made may be read thereon.
It is obvious that this gearing may be modified in its details, for instance, the
internally-toothed ring instead of the spur-wheel may be moved by the excentric,
and the spur-wheel may be allowed to rotate on its axis, while the ring is kept
from rotating.
In a modification of this apparatus I place on the side of the ring a graduated
disc or ring, which may be rotated and adjusted. Adjacent to this ring I arrange
a stationary pointer or index not shewn in the Drawings. At the commencement
of the knitting of each article the said graduated disc or ring is so adjusted that
the said pointer points to zero on the scale. Either on the last named graduated
disc or on the internally-toothed ring I may fix a cam or projection which will
either ring a bell or push or pull a trigger or other device to stop the machine
when a
determined number of rows has been knit.
The said apparatus may be used in combination with the mechanism shewn in
Figure 10, 11, and 12, for the purpose of stopping the machine automatically
after any determined number of rows has been knitted thereon. For this purpose
I provide the internally toothed ring with a cam or projection, arranged to act upon
the aforesaid trigger upon the standard k, either directly or through the medium
of suitable connections.
Another part of my Invention relates to means for automatically knitting ribbed
tops or cuffs. This part of my Invention is illustrated in Figures 21 and 22 of
the Drawings and also in Figure 23, which is a plan of the cam-carrying disc or cap
with my improvements applied thereto.
દ
According to this part of my Invention I arrange, preferably above the ribbing
attachment, the dial f and the cam, cap, or disc of my knitting machine
(constructed for knitting a one and one " ribbed web) an apparatus similar to
that above described, that is to say, this apparatus has an excentric u', a toothed
ring't, and a spur wheel u, as shewn in Figure 22, and is arranged as above
described. The number of teeth in this gearing will vary according to the number
of rows in the ribbed tops. If, for instance, the rib-tops are required to have
60 rows each, I construct the toothed ring t with 60 teeth and the spur-wheel u
with 59 teeth. The cam-cap has pivoted to it at * the out-throw cam v', which
is so constructed that it may be put into and out of action as follows, that is to

page_text: sayUpon the spindle * of the said out-throw cam v I fix a toothed wheel v²
which gears with the toothed periphery of a disc or with a toothed segment
thereon as shewn. This disc ³ is provided with an upwardly-extending portion
having two faces v³, v, adapted to be alternately engaged by the pins t2, 3; these
pins are free to move up and down one in the ring tand the other in its disc t¹, and
are retained in such a position by springs or other means so that when not acted
upon by certain cams or projections hereinafter described they will pass during
the revolution of the said ring and disc above the projecting part and will
therefore not engage with either of its faces ³, To effect the downward
movement of the pin t2 I attach to the wheel u an arm, cam, or projection u²
which as the ring t revolves is brought into contact with the said pin and causes
the descent of the same, so that on a further movement of the said ring it will come
into contact with the surface 5 of the projection v₁ and will cause the disc 3 and
consequently the toothed wheel to rotate thereby, throwing the cam v₁ inward
from the position shewn in dotted lines in Figure 23, so that the butts of the
needles will not engage with and be moved outward by the same, thus causing
the machine to produce a welt at the commencement of the ribbed top for the
reason that the needles in the ribbing attachment are not operated. After two or
more revolutions however of the machine a cam arranged in a groove u³ in the
underside of the wheel causes the second pin 3 to engage with the face v6 and
turn the disc v³ in an opposite direction to that in which it is moved by the pin t2
thus revolving the wheel and throwing the cam v¹ outward to cause the ribbing
needles to be again put into operation.
To produce a row of loose stitches and enable the ribbed top to be readily
transferred to the knitting machine needles and also a row of loose stitches to
facilitate the separation of the various tops one from another, I provide upon the
periphery of the ring t two cams t*, to. These cams are designed to act directly
upon a piece projecting from the cam-block i, so that when and so long as they
are in contact with the said piece they will depress the said cam-block thereby,
causing the machine to knit a loose row of stitches. Or instead of arranging the
said cams to act directly upon a projection on the cam-block they may be arranged
to depress the latter through the medium of a lever or levers.
Or in some cases cams may be arranged on the periphery of the said toothed
ring to effect the shortening as well as the lengthening of the stitch. By the above
described means I am enabled to automatically knit the ribbed tops of a
predeteemined length so long as the machine is supplied with yarn.
Another part of my Invention relates to providing an ordinary circular reversible
knitting machine (so constructed that the needles may be put out of action for
shaping the heel and toe of stockings) with one or more auxiliary sets of cams,
which may be rendered inoperative during the knitting of the heel and toe and
operative while knitting the tubular part of the stocking for the purpose of
accelerating the work, or for knitting stripes or alternate rows of different colored
yarns.
These improved cams are illustrated in Figures 24 to 26 of the Drawings, in
which
Figure 24 is a central vertical section shewing one half of the cam ring with the
ordinary cams of the knitting machine, and
Figure 25 is a similar view shewing the other half of the said cam-ring with a
set of the auxiliary cams.
Figure 26 is an underside view of the cam-cap of the ribbing attachment shewing
two sets of cams.
In Figure 24 w is the ordinary knitting cam, and w³ is a cam-guard.so arranged
that the butts of the needles may be raised above it to put the said needles out of
action. w and w² are up-throw cams which are alternately raised by a cam on the
reversing ring in the usual manner. The cams of this set are always in action
both when knitting the circular part of the sock or stocking and when fashioning

page_text: the heel or toe. The cams w³ and w¹ however may be rendered inoperative by
adjusting and securing them in the position shewn in dotted lines in Figure 25.
In Figure 26 w and w are the ordinary cams, and w³ and w³ are the auxiliary
cams of the ribbing attachment. All of these ribbing cams are rendered inactive
by simply removing a driving pin similar to that shewn at h¹ in Figures 2
and 9.
According to another part of my Invention I add to a circular reversible knitting
machine of the usual type certain improvements by which I am able to knit in
addition to the usual work done on such machines a tubular web of any diameter,
and to narrow or widen such web at will.
I construct this machine so that when the needles are at rest their hooks project
only slightly above the needle cylinder, and so that the upthrow-cam d', Figure 3,
or the cam w³, Figure 24, may be put out of action. I supply the machine with a
ribbing attachment having a dial or ribbing needle-frame provided with the same
number of grooves as the cylinder of the machine, and the out-throw cam of this
ribbing attachment is constructed as shown in Figure 27, so that it will be put out
With this contrivance I
of action while the machine is knitting in one direction.
can by a simple adjustment of the cams cause the said ribbing attachment to knit
only when turned in one direction, while the machine will knit only when turned
in the other direction. A machine so constructed but without the ribbing attach-
ment is capable of knitting a tubular web of an unvarying diameter, according to
the size of the cylinder. It will also knit a flat web of any width up to the whole
circumference of the cylinder, and will narrow and widen such flat web at will,
and even change from flat to tubular work, and vice versa, while the heels and
toes of stocking may be narrowed and shaped by the said machine.
When this machine is supplied with a ribbing attachment it will knit a ribbed
stocking, and with my said improvements it will knit a plain tubular web of any
diameter, from that of a glove-finger to one of nearly double the circumfernce of
the cylinder, and thus tubular web may be narrowed and widened at will.
It is obvious that I may apply this part of my Invention to machines in which
there is no provision for putting the needles out of action for fashioning the heel
or toe.
Having thus fully described my said Invention, and the manner of performing
the same,
I wish it understood that I claim,―
