I, JOHN WILLIAM WATTS, Hosiers Manager of Countesthorpe, in the County or
Leicester, do hereby declare the nature of this invention, to be as follows:-
This invention relates to knitting machines of the cylindrical class wherein the
needle cylinder is stationary and the cams for operating the needles are attached to
the inner surface of a cylinder that is made to revolve around the needle cylinder
when knitting circular web, or made to reciprocate about a portion of the needle
cylinder and needles for knitting a flat web or fashioning a web as in the making of
heels and toes of a sock or stocking.
The cam cylinder I make in one part, and the flange and cog ring I combine in
another part and unite the two by cutting a screw thread on the lower end of tho
cylinder and another screw thread on the inner edge of the flange, then turning the
cylinder into the flange until the depressing or stitch cams are sufficiently deep to
form the required quality of fabric. The cog ring is attached to the underside of the
flange and meshes into the driving wheel in the usual manner and is held in position
by suitable clamping plates attached to the bed of the machine. I drill a number of
vertical holes round the flange, and upon the outer face of the cylinder I attach a
suitable bracket for the reception of a spring or other bolt, whose lower end fits into
one of the vertical holes in the flange. When the size of the loops formed by the
vertical needles is to be varied I raise the spring bolt out of the hole in the flange and
then turn the crank handle which forces the cam cylinder either upwards or down-
wards according to the direction in which the handle is turned. Having arranged
the cylinder in the required position I again let fall the bolt into one of the holes in
the flange.
Another mode of varying the size of loops formed by the vertical or frame needles
is by having one cylinder turned to fit inside another. The outer one having the
flange and cog ring combined with it as described in my former specification of
Patent No. 15,345 A.D. 1885. But instead of fitting a segment of a ring or a com-
plete ring around the circumference of the outer cylinder for the purpose of vertically

page_text: moving the inner cylinder, I use the following improved device. I recess a portion
of the inner face of the outer cylinder beginning at the bottom to a height of
1 inches (more or less). Into this recess 1 fit a ring which is held from falling by
suitable fastenings attached to the outer cylinder so that the inner surface is perfectly
level with the upper part of the inner face of the outer cylinder. I cut various
inclined slots into this ring and put as many studs into the inner cylinder whose ends
project outwardly into the slots in the ring. At a suitable place in the outer cylinder
I cut a horizontal slot opposite the aforementioned inclined ring, upon the circum-
ference of the ring I attach a lever whose outer end projects through the horizontal
slot in the outer cylinder. By moving the lever horizontally, it vertically moves the
inner cylinder thereby varying the loops formed by the vertical needles. The afore-
mentioned lever is held in position by a rack arrangement and the position of the cams
are shown by an indicating finger or other suitable arrangement.
Another part of this invention relates to automatically changing the motion of the
machine from circular or round about knitting to reciprocating knitting and vice versû
and consists of the following:-
To an ordinary driving shaft journalled underneath the centre of the machine I fit
a fast and loose pulley at one end and a bevelled gear on each side of the machine
that meshes into the cog ring underneath the flange of the cam cylinder each gear
having an ordinary clutch device and put in or out of action by a pivoted lever whose
yoke fits into a groovo in the hub of the bevelled gear. The two levers I attach
together in such a manner that both the bevelled gears are out of action of the cog
ring when held in the centre, but by moving the lever more to the right the left gear
is engaged so that the machine is revolved in one direction; and by moving the lever
to the left until the right bevelled gear meshes with the cog ring the machine is
revolved the reverse direction.
The right and left motion may be given to the levers by a projection on a pattern
chain striking the levers in one direction and a spring tending to draw them in the
other direction or by other means governed by the pattern chain. Instead of running
the driving sbatt under the centre of the machine as just described 1 may carry it
along the back and have two short shafts fitted with bevelled gear to their inner ends
and fitted with clutch devices and levers as just described, the said short shafts being
driven with milled gear from the main or back shaft. In certain classes of work it
would not be practicable to run the machine as fast when reciprocating the machine
as when it is turned only one way, so to reduce the speed I use the following device
in connection with the aforesaid double bevelled gear. To the outerside of the loose
pulley on the back shaft I attach a mill gear wheel having fewer teeth than the
other two mill gear upon the same shaft. Opposite this smaller mill gear upon the
outer end of the shaft is a large milled gear that meshes into the smaller on
the back shaft. It will now be seen that if the belt is turned off the fast pulley on
to the loose one, the machine is not stopped but its speed is reduced. Instead of
operating the pattern chain by a cam attached to the can cylinder, I may make the
back shaft revolve the pattern chain and also actuate the levers for throwing the
right and left bevelled gear in or out of action. Another way by which I can auto-
matically reverse the action of the machine from circular knitting to reciprocating
knitting and vice versú is as follows: I fit a horizontal driving shaft in suitable
bearings attached to the frame-work of the machine and fitted at its inner end
with a bevelled wheel that meshes into the bevelled toothed ring attached to the
underside of the flange of the cam cylinder. Near the outer end of the driving
shaft are two driving pulleys, the inner one made fast to the shaft while the outer one
is loose on the shaft. The fast pulley is for driving the machine when knitting
cylindrical web and the loose one for reciprocating the machine for making heels,
toes and flat web. Upon the outer side of the loose pulley is rigidly attached a
small mill toothed wheel and meshing with it is a large mill toothed wheel which
revolves upon an axle that is attached at its base to the framework of the machine
and which has an axle pin projecting from its sides. Parallel with the main driving
shaft, is another shaft upon which is fastened a large toothed wheel gearing with a

page_text: small toothed wheel opposite thereto, on the main shaft, said small bevelled wheel
being adapted to be clutched to said shaft by a lever.
Near the outer end of the second shaft is fastened another wheel which has an
axle pin standing outwardly from its side. A rod connects this axle pin with that
before mentioned. It will now be seen that when the loose pulley is revolved it
carries with it the milled gear which turns the large milled toothed wheel above men-
tioned. The revolving of this gives a crank or backward and forward motion to the
second shaft and therefore to the main shaft. During the operation of making the
round about knitting (i.e, when the machine is being revolved in one direction only)
the fast pulley is the driving pulley and the small bevelled wheel on the main shaft is
drawn out of action, consequently the second shaft is at rest. But when I wish to
commence reciprocating knitting the driving belt is turned off the fast pulley on to
the loose one by a suitable lever that also puts the bevelled wheels on the two shafts
in action. This lever being operated by a cam and springs which is governed by
suitable projections on the pattern chain which is revolved and lies upon a suitable
studded bed and has a driving gear attached to one side that is put in motion by a
cam attached to the cam cylinder in such a manner that whether the machine is being
turned either forwards or backwards it still drives the pattern chain onward one link
at a time.
Another part of this invention relates to the raising and lowering of certain needles
by cams and levers operated either automatically or by hand during the process of
making heels and toes of stockings or at any time when one part of the needles are
required to be at rest whilst the others are in a position for knitting by the cams.
To obtain the required room for operating the needles by levers I use a long needle
cylinder the increased length being on the lower end and which descends below the
bed of the cam cylinder. This cylinder is clamped to the bed of the machine by
screws and thumb nuts in the usual way the said bed being supported by a vertical
bracket descending at the back half of the machine from the cam cylinder bed. Those
needles that are raised out of action and put in again during the operation of making
heels, toes etc., I construct with long heels i.e. the length of the stems below the
needle butts is made to correspond to the increased length of the needle cylinder.
Outside the needle cylinder I arrange a number of radial rocking levers fitting in a
bed that is supported by brackets attached to the bed of the machine. The inner
ends of the levers fitting into recesses formed on the lower ends of the stems of the
needles. Underneath the lever bed I arrange an annular plate that revolves in
one direction around the needle cylinder driven by a ratchet wheel that is operated
by a can on the cam cylinder or by other suitable gear. Upon the upper face
of the plate are a number of projections that correspond to the number of needle
levers, one half of the said projections are in front of the lever pivots and the
other half behind. Each lever has two vertical feet one behind and one in front
of the pivot. As the annular plate is moved round, one of the cams or projections
comes in contact with the hanging foot at the fore end of the lever which raises
it up and the needlo with it until the butt of the needle rises above the guard
cam; when the next course or row of loops is formed another lever and needle is
raised in a similar manner to the first but this time on the opposite side of the
heel and so the operation goes on raising up one needle at each course but always
upon the same side as the yarn carrier is. When all the fashioning needles are raised
I commence at the next course to lower them one by one, one needle being sufficiently
lowered at each course until its butt comes below the end of the guard cam. The
lowering process is accomplished by one of the upright projections on the annular
plate striking against the outer foot of one of the levers which raises it, thereby
lowering the fore end of the lever until the fashioning needle batt is sufficiently low
to be again brought under action of the cams when the next course is knit-another
needle is lowered and so the widening continues until all the fashioning needles are in
action again. The toes are knit in a similar manner to the heels and upon the same
needles. During the process of making heels and toes that portion of the needles
(nearly half) that knit the front part of the stocking are at rest being raised out of

page_text: action as soon as the ankle or the fout pieces of the stocking aro knitted and put in
again when the heel and toe are completed. My improved method of putting these
back needles in and out of action is by fitting a plate into the recess at the foot of
the needles in such manner that they are raised or lowered altogether either automa-
tically or by a hand or foot lover. Instead of cramping the lower ends of the needles
to form the butt and recess for operating the needles I may use steel jacks with the
needles soldered in their upper ends, tho said jacks having the recess and butt formed
on their front edge for the levers and cams to actuato them. When knitting circular
web the ordinary hose weight holds down the work on to the top of the cylinder, but
as soon as I begin to knit a heel or too the hose weight begins to lose its power of
holding down the work because it is held up by the loops on the back needles. I
therefore ailopt the following automatic device.
Inside the vertical needle cylinder [ fit an inverted cone or flat dial with radial
grooves cut in either the upper or under surface, into these grooves I fit jacks that
have butts standing out of the said grooves and whose outer ends are shaped so that
they fit between the vertical needles just above the top of the needle cylinder. Thoy
are forced outwardly at a suitable place in the circle and drawn inwardly just as the
vertical needles are ascending, which not only keeps the web from rising but it also
keeps the loops from turning sideways off the hooks of the needles which they have a
tendency to do without this apparatus. To the lower end of the axle pin that supports
the ribbing attachment (whether the said attachment be vertical, conical or horizontal)
I attach a cam, cone or plate fitted with cams to operate the web holders as required,
the axle pin being attached to the cam plate or cone revolving at the same rate as the
vertical cam cylinder and by the ordinary ribbing arm or a special bracket attached
to the outer face of the cam cylinder. I may arrange these web holders all round the
vertical needles and so dispense with the hose weight or I may only use them at the
front of the machine between those needles that knit the heels and toes. Another
part of this invention relates to an improved method of making mock ribbed hose,
half lose &c. upon this machine. Hitherto when making mock or imitation ribbed
work a certain number of the needles have been removed from the machine prior to
making the leg of a stocking and then when the leg was completed the needles were
again added in that half of the machine that produces the heel. But by my improvo-
ments I dispense with taking out and putting in of the needles by the following
device. I use an ordinary needle cylinder with the needle grooves cut equidistant
all round the cylinder. I next arrange certain needle posts or tricks to stand higher
than the rest (the number varying according to the pattern required) so that as the
needles descend to form their loops a longer thread or bar is formed across the higher
posts which gives to the fabric an appearance of ribbed work. The elevated posts at
the back of the machine when not required to move as when knitting the leg of a
stocking can either be soldered to the needle cylinder or can be made adjustable in
height by being attached to a vertical sliding plate that is held by set screws to the
inner face of the cylinder. The elevated posts at the front of the machine are made
movable so that when desirable they can be lowered to the same level as the other
posts. For raising and lowering the movable posts I use a similar apparatus to that
described by me in the Specification of Patent No. 15,345 A.D. 1885. But instead
of the inner end of the elevated posts being in a line with the bevelled edge of the
cylinder I make them to project inwardly i.e. the inner ends of the elevated posts
hang over the inner surface of the cylinder for the purpose of holding the increased
length of loops formed by the elevated posts until the succeeding course is
finished.
Another part of this invention relates to a transferring device and cam arrangement
for changing the pattern of the web from ribbed to plain without removing the needles
from the ribbing cylinder as is usually done. For this purpose I preferably use a
conical or vertical ribbing apparatus (although I can accomplish the same results
with a horizontal ribbing attachment but not so rapidly) which is supported by a
stationary arm attached to the bed of the machine as described in my former patent
No. 15,345 of 1885. I preferably use jacks in this kind of machine with the needles

page_text: soldered in a slot in their ends as is well understood in the hosiery trade. I also
solder my transferring points into jacks. I use as many transferring points as there
are needles in the ribbing cone and to make room for the transferring jacks to slide
I either widen the ribbing needle grooves sufficiently for two jacks to slide side by
side or I cut a special groove for each to slide in. My transferring points are fitted
to lie on the stem of the needles and are made to rise or descend along their grooves
by a suitable cam race way and switch cams that is situated in the ribbing cam
evlinder.
When the ribbing needles are at work I throw the frame noedles opposite
them out of action by depressing them so that the butts of the jacks run in a groove
formed in the bottom cain cylinder underneath the ordinary working cams which
stops the said needles from knitting and at the same time leaves plenty of room for
the ribbing needles to descend for the purpose of throwing off their loops on to the
stems of the needles. I also form a groove in the upper part of the ribbing cam
cylinder for the purpose of switching the needle butts or jack butts into, alter their
loops have been placed on the transferring points. The needles in the bottom or
frame cylinder that are directly opposite the ribbing needles have a different pattern
butt to the others. I may have them a little longer or in someway made different so
that when I want them to descend out of action I can make them do so by altering a
switch cam that is operated outside the cam cylinder. Suppose I wish to make a
plain sock with a one and one pattern rib top, I put every alternate needle in the
bottom cylinder out of action of the working cams by depressing them until their
butts enter the groove formed around the cam cylinder below the working cams.
then put as many ribbing needles and transferring points in the ribbing cylinder as
there are frame needles depressed out of action taking care that the heads of the
ribbing needles will descend into the upper part of the groove of the said depressed
needles. I make a welt in the usual manner and then knit on sufficient of the one
and one pattern of rib to form the top. I next alter a switch cam in the ribbing cam
cylinder which causes the transferring points to descend down the stems of the ribbing
needles until their points lie just at the back and under the ends of the ribbing needle
latches, when the said latches are turned back with the loops lying upon them. The
transferring points continue to descend which causes the needles to also descend a
little, the loops meanwhile sliding onto the transferring points, the needle latches fall
and then the needles are switched into the upper raceway out of the reach of the
working cams, the ribbing loops are now held upon the transferring points (which
somewhat resemble a pen nib) directly over the grooves in the frame cylinder where
the needles have been depressed, but by altering the switch cam in the vertical cam
cylinder they are raised up until their hooks pass at the back of the transferring
points and so through the old ribbing needle loops. The transferring points next
ascend until their butts enter the level raceway by which tine their lower ends aro
out of the way of the vertical needles and the plain part of the half hose is finished in
the usual way.
[
Other patterns of ribbed fabric can be changed to plain or to a different ribbed
pattern by the use of my improved transferring device in a similar manner to that
just described.
For the production of certain classes of ribbed hosiery goods I preferably use a
horizontal ribbing attachment combined with my improvements upon the same which
are as follows:
Instead of drilling a hole through the centre of the needle dial for the axle pin to
pass through for the purpose of supporting the dial in the usual way-I leave the dial
solid in the centre which allows me more room for the tails or heels of the needles by
which I am enabled to use a longer needle than can be used when the axle is in the
centre-I support the needle dial by screw pins that are put through the dial between
the needle grooves and near the outer edge of the dial. The screw pins being tapped
into a plate that rests upon a collar on the axle pin but not fastened to it-or 1 may
attach the dial to the plate in various other ways.
Between this plate and the needle dial is the ordinary cam plate and cams for

page_text: actuating the ribbing needles in the usual manner which I preferably fasten to the
lower end of the axle pin.
By lowering the top of the vertical needle cylinder I am enabled to knit with the
same pattern needle in the vertical cylinder as I use in the ribbing attachment
consequently by only using one pattern of needle in the dial and cylinder 1 can
change the pattern from ribbed to plain and vice versa with greater rapidity than
when two needles are required.
I may use a similar pattern needle to those described in my former Specification of
Patent No. 15,345 A.D. 1885, but I preferably use the following improved
designs.
In either of the improved designs I preferably solder the two outer stems together
which strengthens them considerably.
These patterns of needles are applicable to all kinds of latch needle knitting
machines but moro particularly where only one pattern is used in making both plain
and ribbed fabrics.
Instead of doubling the lower end of the needle and forming the front of the tail,
the butt and the upper continuation, of such doubled part without other strengthening
than that afforded by the main shank of the needle-I combine with those portions
an additional length or extension of the length in such a manner that said extension
lies as an interior downward extension of the said upper continuation of the butt of
the needle, thus forming the latter of a doubled wire with less liability to fracture,
and giving a more substantial strength to the whole of the lower part of the needle.
The improved needle may therefore be made as follows:-
The needle is doubled at the bottom and said doubled portion extends upward
parallel to the shank and is again doubled downward and formed in the upper
extended face of the butt, the butt, and the front face of the tail, ending below at the
tail Or, the needle may be made as shown in the Specification of my former Patent
abovementioned with the exception that the wire instead of ending abruptly in a small
extension above the butt, is curved downward from the upper end of said extension
and passes down against the shank of the needle into the lower double at the
tail.

Improvements in and relating to Circular Latch Needle Knitting
Machines.
1 JOHN WILLIAM WATTS of Countesthorpe in the County of Leicester, Hosier,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to knitting machines of that class known as circular knitting
machines in which the needle cylinder or holder is stationary and the cams and races
for operating the needles are attached and arranged within a cylinder or annulus
which is caused to revolve around the needle cylinder for knitting cylindrical web, or
to reciprocate about a portion of said needle cylinder for knitting a flat web, or
fashioning a web as in the making of the heel or toe of a sock or stocking.
The following is a description of the improvements reference being had to the
accompanying drawings illustrating a machine, details, and modifications embodying
said improvements.
Like numbers of reference refer to like or corresponding parts throughout the
Figures.
Fig. 1 is an elevation and Fig. 2 is a plan of the improved knitting machine certain
details of construction being omitted for clearness of illustration.
Fig. 3 is a vertical central section through the needle cylinder, cam cylinder, and
ceriain other parts hereinafter described. The said section taken in the plane of the
paper Fig. 1.
Fig. 3 is a vertical central section of the same parts on line A A Fig. 3.
Fig. 4 is a section through cam cylinder wall, cog ring and flange, and fixing
bolt.
Fig. 5 is a cross section. Fig. 6 a plan.
Fig. 7 a side elevation of a part of a cam cylinder driven by bevelled gear from
below.
The holder or bed 1 for the needles may be cylindrical or conical. It is referred
to hereinafter as the needle cylinder 1 such term being intended to include conical
as well as cylindrical needle holders or beds. Likewise the interior wall of the annulus
or ring 2 containing the race ways and cams for operating the needles may have
a corresponding shape such part being hereinafter referred to as the cam cylinder 2.
For driving the cam cylinder 2, a ring 3 having cog teeth is arranged thereon and
a flange 4 is provided for guiding the cam cylinder in its circular travel. The cam
cylinder 2 is made in one part and the cog ring 3 and flange 4 integral in another
part. On the outer surface of the cam cylinder 2 and on the inner surface of the
cogged ring 3 are cut corresponding screw threads so that the cam cylinder may be
screwed into the cog ring. By unscrewing or screwing the cam cylinder more or less

page_text: in the cog ring (the latter being horizontally guided and not vertically displaceable)
the cam cylinder is raised or lowered more or less with regard to the needle cylinder
and the size of the loops in the fabric thereby regulated.
Around the upper edge of the cog ring 3 are arranged a number of holes or
recesses 5 and in a sleeve 6 fixed to the cam cylinder by a screw or screws 7 or other-
wise slides a bolt 8 adapted to project into any of the said recesses 5 in the cog ring.
The bolt is held in such recess by spring 9 and carries at its upper end a lateral
arm 10 sliding in a slot 11 in the wall of the sleevo 6. The bolt may be lifted by the
said arm and may be turned after the arm has left the slot so that it may be hindered
from descending by the resting of the arm on the upper edge of the sleove 6. Fig. 4
shows this arrangement as applied to a conical cam cylinder while Figs. 5, 6, and 7
show the same applied to a cylindrical cam cylinder. In Figs. 5, 6, & 7 also the cog
ring 3 is provided with bevelled teeth for driving by a bevelled wheel in the usual
manner. In Figs. 1. 2, 3, and 4 the cog ring has teeth adapted to be driven by a spur
wheel revolving in the same plane therewith. 12 is the bed of the machine, the
needle cylinder 1 being attached thereto in any suitable manner. 13 is a circular
frame or support carrying at its upper end the track 14 for supporting the flange 4
the latter being retained in said track by an overlapping ring, plates or fingers 15
fastened down on the upstanding outer rim of the track 14. By raising the bolt 8
and turning the handle of the machine so as to revolve the cog ring 4 in the one or
other direction while holding the cam cylinder from revolving, the latter is shifted up
or down in the cog ring 4 until the desired position is attained when the bolt 8 is
allowed to fall into the nearest recess 5.
Fig. 8 illustrates in vertical section Fig. 9 in elevation another mode of varying
the size of loops formed by the frame needles, namely by having one cylinder 16 turned
to fit inside another cylinder 17. The outer one 17 may have the flange 4 and cog
ring 3 combined with it as describes above or the flange and cog ring may be separate
from the cylinder. But instead of fitting a segment of a ring or a complete ring
around the circumference of the outer cylinder for the purpose of vertically moving
the inner cylinder I use the following improved device; I recess a portion of the
inner face of the outer cylinder 17 beginning at the bottom to a height of 14 inches
more or less. Into this recess I fit a ring 18 which is held from falling by suitable
fastenings attached to the outer cylinder. I cut various inclined slots 19 into this
ring and put as many studs 20 into the inner cylinder, the ends of said studs projecting
outwardly into the slots 19 in the ring. At a suitable place in the outer cylinder I
cut a horizontal slot 21, opposite the aforementioned ring and upon the circumference
of the ring 1 attach a lever 22 whose outer end projects through the horizontal slot 21
in the outer cylinder. By moving the lever 22 horizontally it vertically moves the
inner cylinder 16 thereby varying the size of the loops formed by the frame needles.
The feather 23 prevents relative revolution of the two cylinders 16 and 17.
The aforementioned lever 22 may be held in position by a rack arrangement
and the position of the cams be shown by an indicating finger or other suitable
arrangement.
Another part of this invention relates to the driving gear and stopping apparatus
and its purpose is to enable the motion of the machine to be changed from circular or
round about knitting to reciprocating knitting and vice-versa without altering the
direction of the main driving mechanism.
With a conical frame needle cylinder I prefer to drive same by means of a spur
wheel 24 and to drive this spur wheel I journal the shaft 25 thereof in a vertical
pillar 26 and fix on said shaft below the bed of the machine a bevelled wheel 27. A
cylindrical frame needle cylinder however not provided with mechanism hereinafter
described for fashioning heels, toes, etc. may be driven direct by the bevelled cog
ring 3. The gear hereinafter described is applicable with slight modifications to
either construction.
Fig. 10 shows in sectional elevation such driving gear as applied to the driving of
the bevelled wheel 27.
11.
Tion thereof.

page_text: To an ordinary driving shaft 28 journalled horizontally underneath the centre of
the machine I fit a fast pulley 29" and two loose pulleys 30, 31 and a bevelled
wheel 32, 33 on each side of the bevelled wheel 27 adapted to mesh therewith or into
the bevelled cog ring 3 underneath the flange of the cam cylinder Figs. 5, 6 and 7.
The two bevelled wheels 32, 33 are carried by a sleeve 34 common to both, said sleeve
feathered to the shaft 28 and having a groove 35 into which engages the lever 38
pivoted at 39 and connected at its outer end to the end of the bell crank lever 36.
The two bevelled wheels 32, 33 are therefore attached together so that both are out of
action when the lever 36 is held in the centre. By moving the lever more to the
right the bevelled wheel 33 is engaged so that the machine is revolved in one direction
and by moving the lever to the left until the bevelled wheel 32 is engaged the machine
is revolved the reverse direction. The right and left motion may be given to the
lever 36 by a projection on the pattern chain striking the levers in one direction and
a spring drawing them in the other. But I preferably give the right and left motion
by an arm 37 on the cam cylinder or on the wheel 21 striking the lever 36 so as to
deflect the same. Of the three pulleys 29, 30, 31,-29 is a fast one for rotary knitting,
30 is a loose one while 31 is for reducing the speed during reciprocating knitting.
Upon the outer side of said pulley 31 is fastened a small spur wheel 40 which meshes
into a larger spur wheel 41 upon shaft 42, this larger wheel has a smaller one 43
attached to its side which meshes into a larger spur wheel 44 that is made fast to
shaft 28. Also instead of the three bevelled wheels 27, 32, 33. having teeth 1 may
use wheels covered with leather or other suitable material and drive them by friction.
The lever 36 being either weighted or else held tight to the wheels by suitable
springs.
Fig. 12 shows in elevation a modification of the gear aforesaid.
By this modification I am enabled to knit either circularly or reciprocatingly by
only altering the knock out lever once each way during the operation of knitting
either the leg, heel, foot or toe of a stocking. To this end I journal the vertical
shaft 25 in suitable bearings in the framework of the machine; said shaft 25 carries
above the plate (not shown in Fig. 12) a spur wheel gearing into a wheel or spur
ring 3 of the same dimensions attached to the cam cylinder. The shaft 25 carries the
three pulleys 29, 30, 31. The upper one 29 is fast to the shaft and is used for driving
the machine in one direction only when rotary knitting is being done. The centre
one 30 is loose on the shaft and is for stopping the machine and the third pulley 31
is for reciprocating it; upon the underside of this pulley 31 is attached small mill
toothed wheel 45 that meshes into a larger one 46 supported on the axle pin 47.
Parallel with shaft 25 is another shaft 18 carrying a crank arm 49 attached to its
lower end; this crank has an axle pin 50 standing up from its surface. There is
also another axle pin 51 attached to the wheel 46. A rod 52 connects the two axle
pins. Near the upper end of shaft 48 is rigidly attached a large wheel or segment of
a circle 53. having bevelled teeth. Journalled between the two vertical shafts 25
and 48 is another short shaft 54 at right angles to the shafts 25 and 48. On one end
of shaft 54 is a bevelled tooth wheel 55 having about one third the number of teeth
that there are in wheel 53 with which it gears. Near the upper end of shaft 25 is the
bevelled wheel 27 having as many bevelled teeth as there are in wheel 56 on the end
of shaft 54. The bevelled wheel 27 is in this case feathered to shaft 25 and has a
nave 57 into which a groove is formed for a yoke of the lever 58; this lever is pivoted
at 59 to the bracket 60 attached to the bed plate. Pivoted to the lever 58 is a bar 61
hanging vertically, its lower ends sliding in the bush 62. attached to the frame work
of the machine. The bar 6 has a forked bracket 63 attached to it for guiding the.
driving belt. When the lever is in its highest position as shown by Fig. 12 the
machine is being driven at its greatest speed and running in one direction only. When
the lever handle 58 is lowered until the fork stands opposite the central pulley 30 the
machine is then at rest. When the handle is in its lowest position the fork will be
opposite the pulley 31 and the teeth of the wheel 45 will drive the wheel 46. The
machine will then be run at its slowest speed and be reciprocated at each revolution
or part revolution of the cam cylinder. For holding the lever 58 in its highest or
B

page_text: lowest positions I attach a stud or projection G1 to the vertical bar 65 and hang thereon
parallel with the bar 61 a movable lever 66; this lever has two detents 67, 68 attached
to it upon which the stud 69 on the rod 61 rests when the lever 58 is in its highest or
lowest position. The rear end of the lever 66 is curved back and held against the
pattern chain 70 passing over the wheel 71 by a spring or by a weight 72. The
bar 61 has two elastic springs 73, 74 attached to it. These two springs are so arranged
that they are neutral when the lover 58 is in its central position, when the lever is
raised to its highest position the upper spring is compressed as in Fig. 12 and when
the lever 58 is in its lowest position the upper spring is slack while the lower one is
compressed.
Fig. 14 is a section on line B B Fig. 12. The finger 75 on the pattern chain 70
lifts the lever 66 and releases the stud 69.
When reciprocating knitting is being done it is an advantage to be ablo to vary
the stroke of the machine proportionately to the number of needles engaged so for
that purpose I use the device shown in plan in Fig. 14, in elevation in Fig. 15, certain
details being shown in Figs. 16 and 17.
Instead of the single spur wheel 45 as shown at Fig. 12 two spur wheels 76 and 77
are employed gearing respectively with the spur wheels 78 and 79, with the crank
pin 51 between them. This crank pin is held in grooves in the wheels one end being
in a radial groove 80 in one wheel and the other end in circular eccentric groove 81
in the other wheel, these two wheels 78 and 79 have a different number of teeth, one
having one or two teeth more than the other, so that as they are both driven by the
pinion 45 or by two pinions 76 and 7-7 fixed together if found preferable their positions
are altered relatively to one another and the crank pin is drawn nearer to the centre
or sent further away by the circular eccentric groove 81 in the one wheel drawing it
along the radial groove 86 in the other wheel. By this means the stroke of the machine
can be varied as the needles are taken out of work or put in again.
I will now describe the action of the driving gear as shown at Fig 12. When I
wish to knit the leg and heel of a stocking I proceed as follows: I raise the lever 58.
until the stud 69 rests on the detent 67 of the lever 66, the machine then knits rotary
or round about kniffing. When it has knit sufficient to form the leg the stod 75 on
the pattern chain will have arrived under the end of the lever 66 lifting the same
and forcing back the detent 67 until the lever 58 is forced to its central position by
the springs 73 and 74.
The machine stops by the driving belt arriving in the loose pulley 30.
I then tie the splicing thread for the heel etc. and subsequently put the lever 58
down, until the stud 69 is below the detent 68 which puts the helt on the pulley 31
and drives the wheels 45, 46. The machine then commences reciprocating knitting
and it runs at its slowest speed. By the time the heel is finished the next stud on
the pattern chain will have forced back the lever 66 until the detent 68 is drawn from
over the stud 69, the spring 74 will then instantly force up the lever 58 to its central
position when the machine will again stop for breaking of splicing thread &c. prior
to again starting rotary knitting. This driving gear as shown at Fig. 12 is best
where the bottom or frame cylinders are conical, but where I use vertical cylinders
for the frame needles I preferably make a bevelled wheel in place of spur
wheel 24
and the whole apparatus as shown at Fig. 12 (with slight modifications rendered
necessary to change of position) is set at right angles to its position as there shown.
Instead of having the bevelled wheels 27, 53, 55 and 56 I may have the wheels 3
and 27 fitted with spurs to mesh with each other and so dispense with wheels 55 and 56
and the shaft 54.
To
Another part of this invention relates to the raising and lowering of certain needles
by cams and levers operated either automatically or by hand during the process of
making heels and toes of stockings or at any time when one part of the needles are
required to be at rest whilst the others are in a position for knitting by the cams.
obtain the required room for operating the needles by levers 1 use a long needle
cylinder 1 (whether the said cylinder is vertical or conical) the increased length being
on the lower end which descends below the bed of the cam cylinder 2, this needle

page_text: cylinder 1 is fastened to the bed of the machine by screws at its lower end in the
usual way or it may be screwed to a circular plate 12 and the said plate made fast to
the underside of the bed as shown at Fig. 3. I preferably use jacks 82 for this machine
as shown in Fig. 3 the recess 83 in the front edge near the bottom is for the ends of
my rocking levers 84 to work in.
Surrounding the conical needle cylinder 2 Fig. 3 is an annular bracket 13 that is
made fast at its base to the bed of the machine, on the track 14. Upon the upper
surface of this bracket is guided the cam cylinder flange which is prevented from
rising when at work by clamping plates 15 attached to the upper edge of the said
bracket. Between the needle cylinder and the cam cylinder bracket is another annular
bracket 85 made fast to the bed of the machine or else to the bracket this bracket has
as many slots cut at equal distances around its upper edge as there are needle grooves
in the cylinder; into these slots are fitted levers 84 whose inner ends fit into the
recesses 83 of the needle jacks. These levers are pivoted on a wire ring 86 that is
let into a groove 87 which is cut vertically all round the upper edge of the lever
bracket 85 and are prevented from rising off the wire by the plates SS that are
screwed to the bracket 85. The fore ends of the needle levers 84 are rounded and the
recesses 83 in the needle jacks 82 are so arranged that when the butts of the needle
jacks are on the horizontal cam the recesses stand in position for the ends of the
levers 84 to enter. The fore ends of the levers remain in the recess while the levers
are in their highest position. When the cams by which the levers 84 are raised are
withdrawn from under the levers the springs 89 instantly depress the latter and the
needle jacks 82 with them until the levers pass out off the line of the jacks but before
that occurs the butts of the needle jacks arrive low enough for the needle cams to
operate them. The back half of the series of levers 84 are either pivoted higher, or
the bottom edge 90 of the said levers are cut away to make room for the cams that
actuate the heel and toe fashioning machine needles as may be seen from Fig. 3.
Prior to raising the needles for fashioning the heels and toes on the front of the
machine the butts of the needles at the back of the machine must be put out of the
reach of the needle cams and this result I may accomplish in various ways. Thus if
the machine is only making plain work (i.e.) without any ribbing attachment being
used, use needle jacks at the back half of the machine that have much longer butts
than those on the front half and fit a thin switch cam to the cam cylinder that is
operated by a lever outside that, will raise or lower the long butted needles without
interfering with the short ones. If the machine is for making both ribbed and plain
work I then either use longer jacks for the back half of the needles so that their butts
can work in a raceway below the other raceways and then when I wish to commence
heel or toe work I lower the cams that actuate the long jacks and so leave them at
rest. But I preferably use the same kind of needle jacks at the back as at the front
of the machine and pivot levers 84 for raising them. These levers are raised and
lowered altogether out of reach of the needle cams by two bars 91 and 92 loosely
connected together one above and one below the rear projecting arms 93 of the
pivoted levers 84, the clamping bars are connected to suitable levers that are operated
by hand or foot power. The outer ends 93 of the levers may or may not extend
beyond the circumference of the cam cylinder bracket 13 and be operated by hand or foot
lever just described. For raising and lowering the fashioning needles one by one as
is done when making heels, toes &c. I adopt the following device. Underneath the
radial levers S4 and between the needle cylinder 1 and the lever bracket 85 are
two superposed circular plates or rings 93 and 94 with mill teeth on their outer edge.
Figs. 3 and 3 show these rings. Fig. 21 is a plan view and Fig. 22 a vertical
cross section on line cc Fig. 21 of said rings. Fig. 18 is an elevation, Fig. 19 a plan
and Fig. 20 a side elevation showing the means for operating said rings.
On the upper side of each plate 93 and 94 is attached a cam 95 and 96 respectively
for raising the levers 84 of the fashioning needles. The cam 96 on the lower plate 94
stands up within the upper plate the thickness of the upper plate higher from its
base than the cam 95 on the upper plate 93 from its base. Part of the inner part of
the plate 93 is cut away for the lower cam 96 of the lower plate to work in. The

page_text: heels and toes of stockings are made on the front half of the machine and the fashioning
needles occupy one third of the grooves on each side of the front -half. The central
one third of the needles on the front of the machine are never out of action when
-making heels and toes. While knitting the leg and foot piece of a stocking the cams
on the cam plate lie under the levers at the back half of the machine in the position
shown in Fig. 21; as soon as the machine commences reciprocating the knitting cam
plates are moved so that the front ends of the cams approach each other raising a
needle lever for each course that is knitted, next those that are already raised. When
one third of the needles upon each side of the front half of the machine are raised out of
action the movements of the cam plates are reversed the front inclined ends receding
from each other sufficiently far at each course to allow room enough for one radial
lever 54 to fall. To ensure the levers falling I fit a spring 97 to each one, Fig. 3.
For certain classes of work I may also arrange the springs to raise the levers out
of action of the knitting cams and utilize the cams on the cam-plato for depressing
them.
The to and fro movement of the cam plates 33 and 94 is effected by the following
means. At the back or front of the machine is journalled a small vertical shaft 99
Figs. 1. 23 19 and 20 and to the lower end of this shaft is fastened the wheel 98
that meshes into the teeth of the cam plate 93.
To the left of the wheel 99 is also another double wheel 100 revolving on its
axle 101 one part of which meshes into the teeth of the other cam plate 94 and the
other part into the teeth of wheel 98. Near the upper end of the shaft 99 is
fastened a ratchet or toothed wheel 102 for driving the shaft 99.
Upon the end of the vertical shaft and above the ratchet wheel is pivoted the-lever
103 whose outer end is furnished with a double pawl or anchor 104 one pawb acting
upon the right side of the wheel 102 and the other upon the left. The ends of the
pawls are held to the teeth of the ratchet wheel by the springs 105. The inner end
of the lever 103 is situated in the track of the two tumblers 106, 107. The tumbler
106 on the cam cylinder pushes the lever in one direction and the tumbler 107 on the
driving wheel reverses the lever. Sliding vertically in the bearing is the sheath 108
which passes between the pawls 101 and the teeth of the ratchet wheel 102.
This sheath 108 has a recess or bay 109, 110 formed in the edge of each side.
Attached directly or by connecting rod 111 to the lower part of the sheath is the
pivoted lever 112 whose outer end lies over the pattern chain 115. This pattern chain
carries two studs 113, 114 one standing higher above the chain than the other.
There is also another lever attached to the lower part of the sheath, whose outer end
is connected to the knock out lever so that when puiting the knock out lever right
for rotary knitting it also forces the sheath to its highest position. The broad part
of the sheath is then opposite the teeth of the ratchet wheel and although the lever 103
is periodically moved backwards and forwards, by the tumblers 106, 107, it does not
turn the ratchet wheel 102 because the broad part of the sheath holds back the two
pawls. When the rotary knitting is finished the stud on the main pattern
chain 70 stops the machine and the small stud or chain 115 elevates the
end of the lever 112 causing the sheath 108 to be depressed until the
recess 110 on the right side is opposite the teeth of the ratchet wheel 102. The
pawl on the right side then commences to draw the wheel 102 one tooth at a time
cach time the lever is knocked by the tumbler 106 on the cam cylinder until a
sufficient quantity of needles have been raised out of action the large stud 114 on
the pattern chain 115 will have reached the end of the lever 112 which it raises and
further depresses the sheath 108 until the recess 109 on the left side thereof is opposite
the teeth in the ratchet wheel. While the sheath 108 was descending the shoulder
above the recess 110 forced back the pawl on the right side. The ratchet wheel is
then moved the reverse way by the pawl on the left side one tooth each time, the
lever is knocked by the tumbler 107 on the driving wheel when all the fashioning
needles are again in action the machine will be stopped and prior to commencing
rotary knitting the sheath 108 is raised until both pawls 104 are held out of action by
the broad part of the sheath,

page_text: · Instead of cramping the lower ends of the needles to form the butt and recess for
operating the needles I prefer to use steel jacks having the needles soldered in their
upper ends. The said jacks having the recess and butt formed on their front edge for
the levers and cams to actuate them.
When knitting circular web the ordinary hose weight holds down the work on to
the top of the cylinder but as soon as I begin to knit a heel or toe the hose weight
begins to lose its power of holding down the work because part of the work is held up
by the loops on the back needles."
With the object of more efficiently holding down the work when only knitting on a
portion of the needles as when making heels and toes &c., I adopt the following
automatic device or devices substantially as represented in Figs. 23 to 30, Figs. 23, 26
and 28 being vertical part section showing three different modifications. Figs. 24
and 25 detail and modified detail of part of Fig. 23. Fig. 27 plan of cam track or
race way used with Fig. 26. Fig. 29 cam or raceway used in Fig. 28. Fig. 30
detail or modification of Fig. 23. Inside the bottom or frame needle cylinder 1 I fit a
cone, inverted or otherwise or a flat dial 117 with radial grooves cut in either the
upper or under surface. Into these grooves I fit web holders 116 that have butts
standing out of the said grooves. The outer ends of said web holders being shaped so
that they fit between the bottom or frame needles just above the top of the needle cylinder.
They are forced outwardly at a suitable place in the circle and drawn inwardly just as the
frame needles are ascending and not only keeps the web from rising but also keep the
loops from turning sideways off the hooks of the needles, which they have a tendency
to do without this apparatus. I may arrange these wel holders all round the circle
and so dispense with the hose weight or I may only use them at the front of the
machine between those needles that knit the heels and toes.
To the axle pin 119 that supports the ribbing attachment (whether the said attach-
ment be vertical, conical or horizontal) I attach a cone or plate 120 fitted with cam
tracks or raceways 121 for operating the web holders through engagement with their
butts, the axle pin 119 being attached to the cam plate or cone 120 and revolving at
the same rate as the bottom cam cylinder 2. either drive the axle pin by the ribber
arm 122 or by a special bracket attached to the cam cylinder 2. In Figs. 23, 20
and 28 I show the axle pin 119 being driven by the ribber arm 122. A spring
bolt 123 is fitted to the ribber arm as shown at Fig. 23, 26 or 28. The outer end of
the bolt fits a horizontal recess or slot 124 formed in the axle pin 119. The cams
are fitted to a plate or cone as shown at Figs. 11 and 12 the said plate or cone being
rigidly attached to the lower end of the axle pin and held so near the web holding
cone or dial that the butts of the web holders enter the raceway. I arrange the cam
plate or cone on the axle pin so that the out throw cam pushes the web holders out
through the needles just before they reach the yarn guide and withdraws said holders
just as the hooks of the bottom needles are rising out of the grooves in the cylinder.
In reversing the machine, the web holding apparatus rests until the spring bolt 123
catches against the other side of the slot or recess 124 in the axle pin 119; the web
holders will then be pushed out and drawn in the same relative position to the
frame needles as when driving the machine the other way. I preferably use a
conical web holding apparatus, when knitting with a conical ribbing attachment
combined with a conical frame cylinder as shown in Fig. 28. I then cut the required
number of web holding grooves in the inner surface of the needle cone (Fig. 28)
thus combining the needle cone and web holder cone 117 in one part and I fit a cam
carrying cone upon the axle pin, the cams so arranged that they will depress the
web holders just as the hooks of the frame needles are rising out of the cylinder.
(Fig. 28) shows the shape of the web holder I use in the cone and Figs. 23, 24, and 25
show shapes suitable for radial ribbing dial.
Instead of forming a recess or slot in the axle pin as above described I can accom-
plish the same results by forming a horizontal slot in the boss of the cam-plate or
cone and putting a stud through it into the axle pin.
It will be seen that the points of the web holders are hooked or plain according to
the direction of their movement.

page_text: Another part of this invention relates to improved apparatus for the production of
mock ribbed goods such as Hose, Half Hose &c. Heretofore when making a similar
kind of fabric certain needles have had to be removed from the cylinder and put in
again when the plain part of the fabric was going to be knitted. But by my improve-
ments I save the time occupied in taking out and putting in of needles besides making
a far superior article and with less liability to breakages of machine.
Fig. 31 is a part elevation Fig. 32 a vertical section and Fig. 33 a plan of the
improved needle cylinder fitted for this purpose. Fig. 34 a vertical section of the
same with false needle posts or tricks raised. Fig. 35 a vertical section slightly
modified.
The improvements are as follows
I use an ordinary frame needle cylinder 1 with a certain number of slots 125 cut
in the upper edge. Supposing I wish to make a three-and-one mock pattern of fabric
I cut the upper part of every third post or trick away, and also cut a slot 125 in tho
upper edge of the cylinder in a line with the partly removed post. I next fit into
the slots 125, posts 120 that stand higher than the top of the other post that are in
the cylinder see Fig. 17 and also arrange that their inner edges shall overhang or
project over the inner face 127 of the cylinder. These posts may be rigidly fastened
to the cylinder or they may be fitted to adjustable plates that are made to slide on the
inner face of the needle cylinder see Figs. 32, 34, and 35 so that they can be put in
the position shown in Fig. 31 or 35 when the machine will knit plin fabric. For
the making of Half Hose I prefer that the posts at the back of the machine shall be
attached-to-a-sloited-plate 128 that is made adjustable in height by the set screws 129
see Fig. 85 and that those posts that fit between the needles at the front-of-the
machine that knit the heels and toes shall be attached to a plate 130 that is operated
vertically in a similar manner to the one described by me in my former patent No. 15345
A.D. 1885. Fig. 34 shows the posts level with the top of the needle cylinder and
Fig. 30 shows them above or in their highest position with their inner edges standing
away from the needle cylinder. To knit a Half Huse I proceed as follows (When
once the needles at the back of the machine are adjusted the right height they do not
require altering while on that kind of work) I turn the lever 131 so that the vertical
plate 130 rises, carrying with it the movable front posts 126 to their bighest position.
I then knit the leg piece of the half hose, then push the lever 131, lowering the
plate 130 to its lower position and proceed to knit the heel in the usual manner, next
knit the foot piece which will be narrower than the leg because of knitting the bottom
of the stocking plain i.e. with the posts in their lowest position. The toe is knitted
similar to the heel. I then pull the lever 131 raising the posts to their highest
positions and proceed with the leg of the next half hose. If desirable the whole of
the posts may be fitted to the plates so that when the lever is pulled it raises the
whole; then by gradually lowering the said posts tapering fabric may be produced.
I make the posts to project inwardly i.e. the inner ends of the elevated posts bang
over the inner surface of the cylinder for the purpose of holding the increased length
of loops formed by the elevated posts until the succeeding course is finished.
I can make fashioned or shapable fabric with the aforementioned apparatus as
follows
Having the whole of the movable posts in their highest position I knit the desired
length of the maximum width of fabric and then commence to taper or fashion the
web by either gradually lowering the elevated posts until the minimum width is
reached or else by removing two or more posts at a time between every few courses
knitted (the posts being then separately adjustable). If desirable I can knit the
narrowest part of the fabric first and gradually wilen it until 1 get to the widest.
width. My improved way of knitting a shaped or fashioned legged stocking is as
follows I put all the elevated posts in their highest position and then knit from
the top of the stocking to the calf and either gradually lower the posts at the back
of the stocking or else I lower the two centre posts at the back of the stocking and
then knit a certain number of courses say 10. then lower two more, one on each side
of the previously lowered one and so on until the whole of the posts, at the back of

page_text: the stocking are lowered. I then knit sufficient of the small part of the stocking
and afterwards make the heel and foot in the usual manner. Having finished the
toe I may either begin the next stocking at the toe and make it the reverse way to
the one just described, or I may commence at the top of another stocking and pro-
ceed as before. In making cylindrical mock ribbed legs I put the whole of the posts
at their highest position and having knit to the heel I draw down the whole of the
posts at the back of the stocking and proceed to knit the remaining part of the
stocking as usual. Instead of having elevated posts to produce mock ribbed fabric
I can produce the same by arranging the ends of the web holders to remain over
the posts of the needle cylinder until the needles have drawn their loops over them,
and when I arrive at the heel I alter the cams so that they draw the ends of the web
holders in hefore the loops are laid across them.
Another improvement relates to the changing of the pattern of the fabric knitted
from ribbed to plain or vice versa and consists in an arrangement of the needles, cams
and race-ways therefor, and certain novel devices which I have termed "quills" for
transferring the stitches or loops from the ribbing needles to the plain needles or
vice versa without necessitating the removal or insertion of any needles from or into
their respective grooves in either needle cylinder as is usually done.
The improved and novel devices are more especially shown in Figs. 36 to 48.
Figs. 36, 37, and 38 are side elevations of three forms of the transferring points
orquills" Figs. 39, 10 and 41 being respectively plan views thereof. Fig. 42 is
a view of the cut out blank of which the quill Fig. 37 is composed. Fig. 43 is a cut
out blank composing the quill shown in Fig. 88. Figs. 44 and 45 are vertical sections
of frame and ribbing cylinders of conical form and Fig. 46 is a similar view of a
cylindrical frame cylinder and conical ribbing cylinder illustrating the use of the
quills aforesaid. Fig. 47 is a plan view on a larger scale showing the cams and
raceways in the ribbing cylinder. Fig. 48 shows in extended elevation the cams and
raceways in the frame cylinder.
I preferably use a conical or vertical ribbing apparatus (although I can accomplish
the same results with a horizontal ribbing attachment but not so rapidly) the same
being supported by a stationary arm attached to the bed of the machine as described
in the specification of my former patent No. 13345 of 1885. I also preferably use
jacks in this kind of machine with the needles soldered in a slot in their ends as is
well understood in the hosiery trade.
For the purpose of removing the loops off the ribbing needles 132 on to the frame
needles 133 and vice versa I make use of transferring points or quills 134 hereafter
described the pattern of said quills varying according to the quality of work required
and the pattern of cylinders used. For instance if I use a conical frame cylinder in
combination with a conical ribbing attachment, or a vertical frame cylinder in com-
bination with a vertical ribbing attachment I preferably used the pattern of quill as
shown at Fig. 37. The fore end of the quills is made pointed to readily enter the
loop. The sides of the quill rise gradually from the point until each side siands a
little higher than the needle hook, the said hook and stem lying in the quill, the base
or inner end of the quilt is either attached to a steel jack 135 or else the quill and
jack are made out of a piece of sheet steel or other suitable material as in Fig. 42.
1 can use these quills 134 in either the lower frame cylinder or the upper ribbing
cylinder by widening the needle grooves so that the two jacks will slide side by side.
For instance, supposing I wish to use the quills in the ribbing cylinder widen
every needle groove in this cylinder so that two jacks will slide in each groove, onc
carrying the needle in the usual manner and the other the quill. I also widen the
upper end of the grooves of the frame cylinder to make room for the fore end of the
quill to enter during the process of transferring the loops. In addition to the race-
ways 136 that the butts of the ribbing needles occupy when ordinary knitting is
being done, I form two others in the-ribbing cam, cone or cylinder (Fig. 47)
one 137 above the knitting raceways for stitching the needle butts into after their
loops have been removed by and on to the ends of the quills. The other raceway 138
I either form above the raceway 137 or else below the knitting raceway 136 as

page_text: shown by Fig. 47 for the butts of the quill jacks or quills. When I want to remove
the loops off the ribbing needles I put the switch cam 139 in the position as shown
by dotted lines in Fig. 47 when on turning the machine, the butts of the quills are
turned into the raceway 140 while at the same time the quills enter the loops, raising
them up until the needles can be drawn from under without their hooks catching the
loops.
When the ribbing needles are at work the frame needles opposite have to be taken
out of the way of the said ribbing needles, so that the hooks of the latter can enter
the upper part of the frame needle grooves. To facilitate the removal of such frame
needles I form a raceway 141 leading from the knitting raceway into a lower resting
raceway 142 situated underneath the ordinary working cams as shown by Fig. 48.
But as I only require those frame needles to descend that have had their loops removed
from them, I form the butts of those needles that have to be removed into the resting
raceway somewhat differently to those that remain in the knitting pathway. I may
make the butts of such as I wish to remove longer and depress them into the raceway
by a switch cam that is attached to the inner face of the cam cylinder this switch
cam being so thin that it only stands out far enough from the inner face of the cam
cylinder to operate on the long tails of the needles, but preferably I make the following
arrangement the needles that are required to enter the resting raceway 142 have
shorter butts than those that are required to remain in the knitting raceway 143.
After the removal of the loops by the transferring quills I raise the switch cam 144
to its higher position as shown in full lines in Fig. 48. The whole of the frame
needles then descend down the raceway 141 until they reach the adjustable cam 145
which is set to only project sufficiently far from the inner face of the cam cylinder to
operate on the long tails of the needles, which it does, raising them up along the
raceway 146 and underneath the drop cam 147 where they again enter the knitting
raceway, 113, meanwhile the short butted needles have passed into the resting
raceway 142 where they remain until the machine has knitted enough of the ribbed
fabric.
I will now describe the process of knitting a one-and-one rib top to a plain half hose
(assuming that the frame needles have the work hanging on them, and that the
ribbing needles are all out of action with their butts in the resting raceway 137).
Tho two switch cams 139 & 148 Fig. 47 are elevated to their higher position as
shown by dotted lines. Next the switch cam 144 Fig. 18 is put in its higher
position and the adjustable cam 145 is drawn to its most backward position, the
imachino is now turned, the switch cam 139 forces the transferring quills down
until they enter the loops of the short butted frame needles, by the time the butts
of the transferring quills get into the raceway 140 the quills have raised the loops
sufficiently high for the frame needles to pass under the loops without the hooks
catching them. The switch cam 144 being raised to its higher position shunts the
whole of the frame needles down the raceway 141 until they arrive at the adjustable
cam 145 which has already been drawn far enough back to allow the short butted
needles to pass it on their way to the rest raceway.
The long butted needles are drawn up the raceway 146 by the adjustable cam 145
and passing under the drop cam 147 arrive into the working raceway 143 again.
In the meantime the ribbing needles have been brought out of the rest raceway 137
by the switch cam 148 into their working raceway 136 their hooks passing down the
transferring quills while the frame loops are still on the quills. When the hooks are
sufficiently low and with their latches open the transferring quill butts pass out of
their lower raceway 140 into their resting raceway 138 that action causing the
quills to slide from under the loops, allowing them to settle on the open latched
ribbing needles.
After one revolution of the machine the transferring process is completed, the
switch cams 139 and 144 are returned to their former position. I then make a welt
in the usual manner and afterwards knit on sufficient one and-one rib to form the
top of the half hose and then transfer the loops of the ribbing needles on to the frame
needles as follows.

page_text: The switch cam 139 is put in its highest position again and the switch cam 1-48 is
put in its lower position while the adjustable cam 145 is thrust into its most inward
position. The machine is now revolved causing the following changes to take place;―the
transferring quills are forced into the loops on the ribbing needles until the said loops
rise higher than the ribbing needle hooks. The ribbing needles then rise until their
butts again enter the resting raceway 137 in the meantime the adjustable cam has
been gradually bringing up the short butted frame needles from out of the resting
raceway to the knitting raceway and as the butts rise up the inclined raceway their
hooks pass under the loops that are held by the transferring quills when the frame
needles have risen sufficiently high the butts of the transferring quills rise into their
resting raceway 138 leaving the loops on the frame needles. After one complete
revolution of the machine the transferring process is completed and the switch cam 139
is again put in its lower position. The plain part of the half hose is next made in the
usual manner.
If I wish to mako three patterns in one half hose eiz., a one-and-one top, a three and
one leg and instep with a plain heel, bottom and toe I then make three lengths to the
needle butts in both ribbing and frame needles and adjust the switch cams and
the adjustable cam so that they occupy three positions in their to and fro movements
from the needle beds.
Instead of taking the loops off the ribbing needles as just described I may
arrange the quills to slide in the grooves in the bottom or frame needle
cylinder.
In that case I dispense with the transferring quill raceway in the upper or
ribbing cylinder and arrange a rest raceway 149 working raceway 150 and cam 151
either below the ordinary knitting raceway 143 or above the knitting cams as
shown by Fig. 48. The quills enter the loops and take them off the needles in a similar
manner to that described above with the raceway in the upper ribbing cam cylinder.
The raceway 149 is the resting groove while the switch cai 151 puts the quills into
the transferring racoway 150.
When I use quills in the frame needle cylinder I either cut special grooves for
them to slide in or else widen the needle grooves and arrange them to slide in along
with the needles, the needle stems lying in the centre of the quills.
When the quills slide in the bottom cylinder I widen the lower part only of the
grooves in the ribbing needle cylinder and dispense with the raceways 138 and 140
shown in Fig. 47.
When I wish to remove the loops off either the frame or ribbing needles I put the
switch cam 151 in position as shown in Fig. 48 then, when the machine is turned the
points of the quills enter the loops and by the time their butts arrive in the
raceway 150 the loops are sufficiently raised above the hooks from the needles to
draw from under them without catching them the needles being switched into their
resting raceway, the hooks of those needles in the opposite grooves are brought down
under the loops and the quills are again put in their resting raceway.
Another mode of taking the loops off the needles in either the frame or ribbing
cylinders is as follows. With this mode of transferring it is also immaterial whether
the quills slide in the frame cylinder or in the ribbing cylinder. I use the same
pattern of quills as those just described Fig. 37, but instead of the butts of the quills
descending or ascending the whole of the incline raceway according to which cylinder"
the quills occupy. I form an intermediate stage so that when the points of the quills
have penetrated the loops, the butts run on a level raceway, while the loops are
pressed off the needles leaving the said loops on the points of the quills. After the loops
have been pressed off the needles, the said needles are switched into their resting
raceway, meanwhile the quills are further pushed until the sides of the quills have
elevated the loops high enough for the hooks of the opposite needles to pass under
them. When that is done, the quills again enter their resting raceway.
If the frame needles work in a vertical cylinder and the ribbing needles in a conical
bed I preferably use the pattern of quill shown in Fig. 38. Instead of the quills
0

page_text: being solid like those shown in Figs. 36 and 37 I form a hole 152 in the quill,
and also slit the quill from the pointed end to a short distance above the hole.
The quill shown in Fig. 38 is soldered to a steel jack and slides in the needle cone
with its two edges on the bottom of the groove, the pointed end lying on the stem of
the needle. To take the loops off the ribbing needles I depress both the needles and the
quills until the points of the quills lie at the back of the needle latches as shown on
the right side of Fig. 46.
They are both further depressed until the loop then slides off the latch on to the
point of the quill. The needle is then raised to the resting raceway while the quill is
further depressed.
While the quill was being lowered the needle in the frame cylinder was being
raised out of its resting groove until its hook passed under the loop and through the
hole 152 in the quill as shown on left side of Fig. 46; the quill now ascends, the
upper part of the frame needle passing through the slit 153, the loop being left on
the frame needle as the butt of the quill enters the resting raceway.
By a slight modification I am enabled to transfer the loops off the ribbing needles
which slide in an inverted cone in a horizontal dial on to the frame needles in the
bottom cylinder. Instead of the points of the quills standing in the general line of
the quill as in Fig. 37 I turn the points backward as in Fig. 36 and I also cut small
recesses in the top of the needle cylinder for the tops of the quills to lie in when they
aro depressed to their lowest position.
I also form on the edge of the ribbing dial or cone a small vertical groove in front
of each ribbing needle groove for the purpose of guiding the points of the transferring
quills into the loops.
Before taking the loops off the ribbing needles I first put the ribbing needles in the
position they are when inaking the welt (ie. 1 open the switch cam 154 as shown by
dotted line in Fig. 51) which keeps all the switches on the needles. I next shift the
cam plate forward until the out-throw ribbing cam is in a line with the switch
cam 151 in the bottom cylinder and I put the welt switch cam in its previous position
as shown in Fig. 51. I next put the switch cam 151 in its lowest position and the
adjustable cam 145 close to the needle cylinder and move the machine forward. The
butts of the quills run upon the switch cam 151 and their points np the vertical
grooves in the ribbing dial or cone, meanwhile the ribbing needles have been pushed
forward by the out-throw cam and drawn back, but as there was not any yarn fed to
these needles when the latches were opened the loops are pressed off the ends of the
needle and fall onto the point of the transferring quills or the quills may have
penetrated the loops hanging underneath the ribbing needles prior to the needles
casting them off. The quills are next raised to their highest position, the loops
sliding down the quills. The hooks of the short butted needles then pass under the
loops and the quills recede to their lowest position.
After one complete revolution of the machine the transferring process is completed.
The ribbing needles are kept back in their grooves by putting the switch cain 154
in the position shown by dotted line in Fig. 51.
The switch cam 151 is then raised to its highest position and the plain part of the
knitting is proceeded with.
Instead of putting the transferring quills in the bottom or frame cylinder I can
.accomplish the same results by putting the quills in the ribbing dial or cone and have
also devised a modified form and construction of transferrer for this purpose.
Fig. 49 is a vertical central section of a radial ribbing attachment fitted with said
transferrers. Fig. 50 is a plan thereof. Fig. 51 shows the needle raceways and
cams. Fig. 52 the transferrer raceways and cains. Fig. 53 is an elevation and Fig. 54
a plan of the transferrer.
Sliding in the same grooves as the ribbing needles 132 are the transferrers 155,
patterns of which are shown in Fig. 33. The butts of the transferrers are turned the
reverse way to the butts of the needles the butts of the transferrers passing through
vertical slots 157 cut through the dial 158 and projecting below the underside of the

page_text: dial 158 sufficiently for themi to be actuated by cams and races on a cam plate 159.
The transferrers or points may also be fitted to slide in grooves on the underside of
the dial 158 cut directly under the needle grooves, or be fitted to slide at the bottom
of the ribbing needle grooves, the said needles sliding on the top of them as shown in
Fig. 49. The cams for operating the transferrers are shown on their cam plate at
Fig. 52 and the cams for operating the radial ribbing needles are shown on their
plate at Fig. 51. The cam plate for actuating the transferrers is rigidly attached to a
hollow axle pin 160 supported by the ribber arm 122 the said axle pin being connected
to the ribber arm by a spring bolt or feather 123.
The resting raceway is shown by the figure 161.
The switch cam 162 is for the purpose of bringing the transferrers out of the
resting raceway 161 into the working raceway 163.
A knob 164 attached to the top of a rod 165 that passes down the hollow axle
pin 160 and descends a little below the transferring cain plate 159. On the lower
end of this rod is fastened a disc or crank 166 having a stud attached to its surface.
To the lower side of the switch cam 162 is fastened a tang or crank 167 which works
in a slot in the cam plate 159 a rod 168 connects the disc 166 to the tang 167 so that
by turning the knob 164 at the top of the axle pin one way the switch cam is placed
in the position shown in full lines and by turning the knob the reverse way the switch
cam is placed as shown by dotted lines in Fig. 52.
The horizontal needle dial 158 and the needle cam plate 169 fit loosely on the
axle pin the dial resting on the boss of the transferring cam plate and kept from
revolving in the usual way. The cams for operating the needles are shown in
Fig. 51.
The switch cam plate 154 is moved from one position to the other by a thumb
nut 170, which is made fast to a shank that passes through the cam plate; there is
also a spring washer placed between the thumb nut and the cam plate for holding the
cam steadily. 171 is the resting raceway where the needles are switched into after their
loops have been removed on to the transferrers and also when the machine is making
a welt. 172 is the working raceway where the butts of the needle slide when ordinary
ribbed work is being done.
I
may also fit a small brush to the bottom cam cylinder or other suitable place for
the purpose of turning back any ribbing needle latches that may be closed when the
said needles are being pushed down under the quills to have the loops laid on them.
The transferrer shown in Figs 53 and 54 is formed of steel wire. 173 is the butt
whence the wire projects in one direction to form the point and in the other direction
to form the heel, the wire being bent up or doubled at the heel and projecting along
the main stem to form a point projecting into a recess 174 in the main stem this lateral
stem being slightly curved outward as shown, for the passage of the frame needle
between the stems.
Another part of this invention relates to improvements by which I am enabled to
produce certain classes of hosiery ribbed goods without having to use two patterns of
needles as is usually done when a horizontal or inverted conical ribbing attachment is
used in combination with a vertical frame needle cylinder.
Instead of drilling a hole through the centre of the ribbing needle bed to allow the
axle pin to pass through for supporting the said bed 1 leave the centre solid and do
not pass the axle pin through the same this allows a free space for the tails of the
needles to slide in.
Referring to Fig. 55 a vertical section and Fig. 56 a plan view of a radial ribbing
attachment formed on the improved system. I support the needle bed 175 of the
ribbing attachment by pins or pillars 176 fastened between the needle grooves near
the circumference of the said needle hed (whether it be conical, horizontal, or an
inverted conical one) the upper ends of said pins being shouldered down and tapped
to pass through boles in the ends of the extended arms of the supporting plate 177.
Screw nuts 178 are fitted to the upper end of the pins as shown at Fig. 55. The
supporting plate 177 rests on a collar 178 that is fast to the axle pin. The needle bed
and supporting plate may be kept from revolving by a stud or studs on the underside

page_text: of the needle bed lying against the upper end of adjustible posts, made fast to the bed
of the machine. The plate or cone 169 carrying the cams for operating the ribbing
needles is rigidly attached to the lower end of the axle pin so that when the axle pin
is turned it carries the cam plate or cone with it. The upper end of the axle pin may
have a solid head resting on the boss of the ribber arm 122 or I may rigidly attach a
disc to the upper end of the axle pin above the ribber arm the said disc being fitted
with a spring or other bolt whose lower end projects downward so that when the
ribler arm is revolved it will catch against it thereby causing the axle pin and
cams to revolve but I preferably use the following device for revolving the axle
pin.
To the upper part of the ribber arm I fit a spring bolt 12 whose projecting end
passes into the boss of the said arm. Into the side of the axle pin opposito the hole in
the boss I drill a hole or deep recess for the end of the spring bolt to fit in. When I
wish to disconnect the ribbing attachment for making heels &c. I withdraw the spring
bolt 123 out of the recess in the axle pin and depress the thumb lover thereof to the
right below the shoulder of the bracket which holds the bolt. My improved ribbing
cam consists of a movable switch cam for the purpose of changing the needle butts out
of the working raceway into the resting raceway and vice versa by which I am enabled
to have the ribbing cams of one uniform thickness.
The outthrow cau Fig. 51 is stationary, being rigidly attached to the cam
cylinder.
The switch cam 154 has a shank or tang riveted into its side, which passes
through the cam plate and is movably clamped to the plate by a thumb
-nnt 170,-
A spring washer resting on the shank between the top of the plate and thumb
nut for holding the cam steady. To make a welt I turn the thumb nut 170
until the cam 154 is in the position shown by dotted lines Fig. 51; the needle
Butts then all enter the resting raceway 171 which prevents them from throwing
off their old loops or taking bolt of new ones while the frame needles knit the required
number of courses to form the welt. When that is done the switch cam is put in
the position shown at Fig. 51 which puts all the needles in the knitting raceway
again.
I lower the top of the bottom needle cylinder so that the same needle that works in
the ribbing attachment will also work in the frame cylinder without drawing a dispro-
portionate loop to those made by the ribbing needles.
The cams for operating the frame needles are made thick so that as the needles
descend in forming their loops the neelle latches are free to rise or fall without their
ends catching on the inner surface of the cam cylinder. To make room for the ends
of the opened latches when the needles are depressed I recess the central part of the
depressing cam 180 as shown in Fig. 61 which prevents the said latches from jamming
on the top edge thereof.
The cam ring and yarn carrier are of the usual construction.
I may use needles of the pattern shown in my former, patent No. 15345 A.D. 1885,
for this class of knitting. But I preferably use the needles shown in Figs. 57 to 02
which comprise the following improvements.
Instead of doubling the lower end of the needle and forming the front of the
tail 181, the butt 182 and the upper continuation of such doubled part without other
strengthening than that afforded by the main stem of the needle. I combine with
those portions an additional length or extension of the length 184 in such a manner
that said length lies as an interior downward extension of the said upper continua-
tion 183 of the butt of the needle thus forming the latter of a doubled wire with less
liability to fracture and giving a more substantial strength to the whole of the lower
part of the needle. The improved needle may therefore be made as follows.
The needle is doubled at the bottom, and said doubled portion extends upwards
parallel to the shank and is again doubled downward and formed in the upper extended
face of the buit 183, the butt 182 and the front face 181 of the tail ending below at
the tail (Fig. 59). Or the needle may be made as shown in the specification of my

page_text: former Patent abovementioned with the exception that the wire instead of ending
abruptly in a small extension above the butt is curved downward from the upper end
of said extension and passes down against the shank of the needle into the lower double
at the tail.
Or the wire may be bent substantially as before described and represented in
Figs. 57 and 58 no continuation 183 being made above the butt. By using such
needles as shown in this or in my former Patent abovementioned I am enabled if
necessary to change the needles from the ribbing to the frame cylinder or vice versa
without loosening the loops from the stem of the needle since said loops are enabled to
slide upon the stems down into the heels of the needles.
