Knitting Machine.
We, JOSHUA DARLING HEMPHILL, Inventor, and WALTER WATKIN RADCLIFFE,
Manufacturer, both of Shelton, Connecticut, United States of America, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following state-
ment:-
This invention relates to that type or class of circular knitting machines in
which web-holders or sinkers are employed, co-operating with latch needles in
forming the knitted articles, particularly stockings and half-hose; and the inven-
tion has special reference to that type or class which are adapted to knit complete
seamless stockings, with heel and toe portions composed of a different yarn, and
in which all of the operations are accomplished automatically.
Among the objects of my invention, are the dispensing with the usual plurality
of picker cams for rendering the needles inoperative and again active, one by
one, during narrowing and widening, and substituting therefor a single picker
capable of producing these results; the provision of improved yarn-changing
mechanism; the production of means for lengthening the stitch by raising the
needle cylinder; the provision of means whereby the web holders or sinkers may
be readily removed and replaced and changed from one side of the machine to
the other; the provision of means whereby the needles may be readily removed
and replaced; and in general, the simplification and reduction of cost of machines
of this type, and to increase their durability and certainty and rapidity of action.
To these ends, the invention consists in the construction and combination of
parts substantially as hereinafter described and claimed, referring to the accom-
panying drawings, in which similar reference characters designate the same or
similar parts in all the views.

The bed of the machine is supported by a suitable frame 2 mounted on legs 3,
a cup-shaped bearing 4 being formed below said bed as shown most clearly in
Fig. 7, and to which reference will be made hereinafter.
The main shaft of the machine is represented at 7, and is provided with the
large bevel gear 8, secured thereto at one end while the other end is mounted in a
sleeve 9 to which is secured a single driving pulley 10 having a crank handle 11
as is usual for hand working of the machine. A single loose pulley 12 is mounted
on an extension of the hub of the driving pulley. Loosely mounted on the shaft
adjacent to the gear 8, is a pinion 13, while the inner end of the sleeve 9 is formed
as a p'nion 14. Between the pinions 13 and 14, the shaft is provided with a
clutch hub 15, the said shaft being formed angular or provided with a feather, to
permit the hub to slide thereon while held from independent rotation thereon.
The said clutch hub is shown in Fig. 17 as provided with two projections cr
teeth 16 to engage a groove in one or the other of the pinion 13, 14, and is also
provided with an angular groove 17 to receive pins or rollers 18 carried by a
lifting yoke 19, said yoke being secured to one end of a rock shaft 20 (see Figs. 2
and 26) mounted in a bearing 21 and oscillated by mechanism described hereinafter.

page_text: A gear 22 (see Figs. 1 and 2) is mounted in a suitable bearing supported by the
frame and meshes with pinion 14 and is constantly driven thereby during the
operation of both the round and round work and heel and toe knitting operation.
Said gear 22 is provided with a crank pin 23 (see Fig. 1) to which is connected
one end of a pitman 24, the other end of said pitman being connected with one end
of an elbow lever 25 mounted on a shaft 26, supported in standards 27.
other end of the lever 25 is provided with a segmental gear 29 which meshes
with pinion 13 on the main shaft, see Figs. 1, 1, 2 and 7.
The
It will now be understood that when the clutch hub is in engagement with
the pinion 14 which is constantly driven, the gear
will be rotated continuously
in one direction, since both the gear 8 and the clutch hub are non-rotatable on
the shaft. During this time, the segmental gear is imparting a rotary reciprocat-
But when the clutch

hub is shifted to engage the pinion 13, it is disengaged from pinion 14 which
latter then, through gear 22, pitman 24, lever 25, segmental gear 29, pinion 13,
and clutch hub 15, imparts to the shaft and to the gear 8, a rotary reciprocating
motion. The motion of the elbow lever imparts movement to the pattern chain
and to certain cams, through the medium of pawls, by the mechanism now to
be described.
Referring to Figs. 1, 2, 3, and 19 to 25 inclusive, a shaft 30 is shown as mounted
in bearings 32 supported by the frame. Loosely mounted on this shatt is a
ratchet 33 to one side of which is secured the pattern chain pulley 34, said pulley
having the usual teeth to engage the links of the pattern chain 35, some of said
1.nks having the lugs or cams 36. The ratchet 33 and pulley 34 are driven in
the direction of the arrow shown in Figs. 19 and 20, by means of a pawl 37
pivotally connected with one end of an elbow arm 38 (see Fig. 1) mounted on
Shaft 26, the other end of said arm 38 being secured to the side of the elbow
lever 25 by means of a bolt 39 passing through a slot 40 in the arm 38. A bracket 11
is secured to the frame of the machine (see particularly Fig. 2) and bolted to
this bracket is a shield 42 on which the pawl 37 rides during a portion of its
stroke. The shield is secured firmly to the bracket by means of a single bolt, by
means of which said shield may be readily raised or lowered to permit the al
to engage a tooth of the ratchet at a point more or less remote from its extreme
forward limit of motion and thus adjust the amount of feed imparted to the
pattern chain.
A ratchet 43 (see Figs. 2, 21 and 23) is secured to the shaft 30 on the opposite
side of the pulley 34, and this ratchet, which may be termed the cam driving
ratchet since it rotates the cam carrying shaft 30, is adapted to be intermittently
rotated by means of a pawl 44 when permitted by the lugs of the chain. The
pawl 44 like the pawl 37, is also pivotally connected with the elbow lever 25 an
is reciprocated thereby, said pawl 44 normally riding on a shield 45. The said
shield is pivoted on a pin 46 carried by the bracket 41 and extending over both
ratchets and the chain pulley, and the shield is provided with an arm 47 having
a pin 48 which projects into the path of movement of the chain lugs. A spring 49
is coiled about the pin 46 and tends to hold the arm and shield in the position
shown in Fig. 21; but when a chain lug raises the pin 48, the shield 45 is depressed
and the constantly reciprocating pawl 44 engages a tooth of the ratchet 43 and
advances the latter and consequently partially rotates the shaft 30 and the cam
disks carried thereby which are yet to be described.
Adjacent to the ratchet 43, a clutch operating cam disk 50 is secured to the
shaft 30. This disk is shown in Figs. 22 and 23 as cut away at one side ter
lightness. It is provided with four grooves 51 in its periphery, these proves
being formed in alternately opposite directions as shown in Fig. 2 and as indicated
by the dotted lines in Fig. 22. The rock shaft 20 heretofore described in con-
nection with the clutch hub 15 (see Fig. 26 in connection with Figs. 12 and 7)
is provided with an upwardly extending arm 52 at its front end, to the side of

page_text: which is secured a spring arm 53 the lower end of which extends below the rock
shait and engages the cam disk 50. The width of the periphery of the disk 50 s
greater than the arc of movement that would be naturally given to the lower end
or the arm while the clutch hub 15 is moving from one of the pinions 13 or 11
to the other; hence the arm 53 is made somewhat elastic and its lower end bears
with considerable pressure against one side or the other of the periphery of the
disk 50. This elasticity of the arm causes it to enter the grooves 51 alternately,
as the disk is rotated, the further rotation of the disk immediately causing the
inclined side of the groove into which the arm has sprung to force the arm over
to the other side of the disk, thus shifting the clutch hub.
It is to be understood, of course, that one complete rotation of the shaft 30 and
its cams takes place during the knitting of one stocking, the length of the article
and its shape being controlled by the length of the chain employed and the spacing
and number of the lugs carried by said chain. The knitting operation itseit
continues uninterruptedly without regard to the rotation of said shaft and cams,
and will be described hereinafter. But when a stocking is finished, however, the
rotation of said shaft effects the automatic stoppage of the entire knitting opera-
tion and during the single rotation of the shaft, it also effects two temporary
shifts of the driving belt to slow down or ease off the machine when the clutch
hub is moved into engagement with the pinion 13. This movement of the hub
changes the knitting from circular or round and round work to the narrowing
or widening at heel or toe, one half of the needles being thrown out of action,
as hereinafter described. During the narrowing or widening, the knitting cams
have a reciprocating rotary motion through the segment and other gearing here-
inbefore described, and the change to this motion from the continuous rotary
motion causes a resistance which renders it desirable to provide for slowing down
or easing off the machine as mentioned. The means for doing this will now be
described.
At one end of the shaft 30, the right hand end in Fig. 23 (see also Figs. 1 and 2),
there is secured a disk 60 having three cam lugs 61 on its side near the edge.
These are adapted to operate successively against a pin or roller 62 carried by a
lever 63, pivoted at 64 to the frame of the machine, the lower end of the lever
being acted on by a spring 65 to keep the pin or roller in engagement with the
cam disk.
The upper end of the lever 63 carries a belt guide 66 of the usual
type for shifting a belt, curved partly around the belt pulley, and adapted to
shitt a belt (not shown) from the fast pulley 10 (see Fig. 7) to the louse pulley 12
when a cam 61 acts on the shipping lever, and rice versa when the cam 61 leaves
the pin of said lever, the spring 65 causing the return of the lever.
The lever 63 is provided with a handle 67 and with an upwardly extending
finger 68 which is adapted to move under and be held by a spring latch 69 sccured
to the frame (see Fig. 2) whenever the lever 63 is moved to its limit of motion
for throwing the belt off from the fast pulley. One of the cams 61 on the disk 60
is of a height sufficient to throw the lever to this limit of movement so that the
lever will be retained by the spring latch, and the driving belt held on the loose
pulley, thus stopping the machine. To start the machine, it is only necessary to
lift the spring latch and permit the spring 65 to cause the belt shipping lever G
to restore the belt to the fast pulley, it being understood that the movement of
the disk 60 which caused the lever to be caught by the spring latch, was sufcient
to carry the cam lug just beyond the roller 62 of the lever. The other two cam
lugs 61 are of a thickness sufficient to cause the lever to shift the belt onto the
loose pulley, but not to cause the lever to be engaged by the spring latch, and
hence the power is thrown off the machine but momentarily, and these two last
mentioned cams are so located on the disk 60 that the power is thrown off only
at the moment when the change in the knitting above described is taking place.
The cam lugs are of a length to be brought under the roller 62 to opera the
lever 63 and to pass beyond it during the time that the pawl 44 (see Fig. 21 is
making one stroke to partly turn the shaft 30 and its cams, the belt barely

passing off the fast pulley before it is shitted back again. The cup shaped bear-
ing supports the cam ning U winch is provided with bevel teeth that are engaged
by the teeth of the gear 8. This cam ring, as has been herein before inentioned, is
revolved continuously to produce circular or round and round work, or is given
a rotary reciprocating motion to produce heel and toe work. While doing the
latter, substantially one half of the needles are first thrown out or action and a
portion of the remaining needles are then thrown out of action, one by one, to
Barrow, and then restored in the reverse order to widen. Before describing the
mechanism for doing this, however, we will first refer to the support and con-
struction of the needle cylinder 72 in the vertical grooves of which the needles 71
are fitted to reciprocate, each of said needles having a heel 13 to be operated
upon by the knitting cams, the picking finger, and the cams for throwing part
of the series of needles out of action and back again. As has been mentioned,
the cup shaped bearing 4 is supported by and below the bed 1, by the frame.
The needle cylinder extends through a central opening in the cam ring (see Fig. 7)
and rests upon an annular shoulder 74 formed upon a web guide 75 which has a
portion of one side cut away as shown. The upper end of the said web guide,
which is cylindrical, extends within the needle cylinder, and the lower end, which
is also cylindrical, is steadied within a ring 76 secured to and supported by two
rods or bars 77 which are bolted to and depend from the bottom of the cup shaped
bearing 4. The ring 76 is provided with a projecting lug or car 78 (see Fig. 1
in connection with Figs. 2 and 3) to which a block 79 is secured by means of a
bolt SO. A stop consisting of a bolt 81 extends vertically through the inner
end of the block and projects above the same.. The web guide 75 normally rests
on the stop except when raised for lengthening the stitch as will be described
hereafter, and said web guide, in turn, supports the needle cylinder by means of
the shoulder 74. Owing to the stop 81 being adjustable in the block 79, the
normal elevation of the needle cylinder may be adjusted to alter the length of
stitch.
The construction and operation of the knitting cams will next be described :-
A cam web 82, which forms about three-fourths of a circle (see Fig. 10 in con-
nection with Figs. 5 to 9 and 13 to 16) is formed at each end with an incline or
cam 83 and is secured to the ring 70. The cams 83 act on the heels of the
needies to raise them during the knitting operation, the said heels riding on the
top of the web after being raised until acted on by one of the draw cams presently
described. During straight or round and round kmitting, but one of the cams 83
acts; but on heel and toe work, when the cams are all given a rotary reciprocating
movement as before described, the two inclines or cams 83 act alternately to raise
the needles. The two draw cams 84, to lower the needles and draw the loops of
yarn, are substantially the same in construction (see Fig. 6 in connection with
rigs. 5, 8, and 17) except that their cam surfaces face in opposite directions toward
each other. In Fig. 8 one of these cams is shown in the act of drawing down
the needles at the right. Each cam 84 is formed on the end of a block 85 which
is secured to a plate 86 on the inner end of a slide 87, said slide being fitted to
reciprocate in a direction radial to the needle cylinder, in a guite block 88 secured
to the ring 70. A spring 89 is confined between the outer closed end of the block 88
and the lide, the latter being preferably hollow to permit a longer spring to be
employed, as indicated by dotted lines in Fig. 6.
The upper surfaces, as well as the lower surfaces of the cams St are shown as
inelined, the function of the upper inclines being to complete the raising of the
needles after they have been acted upon by the picking finger in heel and toe
work.
The fares of the blocks are substantially flat (see Fig. 6) and hence, when one
of the cams is travelling backward around the needle cylinder, it rides over the
outer ends of the luals or needle, the ring S!) permitting the entire block and
cam to be moved outward. In Fig. 6 one of the draw cams is shown as pushed
away from the needle cylinder by this action, while the other cam is pushed toward

page_text: the cylinder by its spring and the point of the cam is in position to engage the
tops of the needle heels and move them down. This is during round and round
work. During heel and toe work, the rotary reciprocating motion of the cam
ring causes first one cam 84 to operate, the other being pushed away as described,
and then on the reverse movement, the activity of the two cams 84 is reversed.
Having now described the knitting cams and their operation, we will next
refer to the means for rendering a series of the needles inactive when heel and
toe work is to be commenced: As indicated in Figs. 6, 7 and 16, substantially
one-half of the needles are provided with heels longer than those of the other
needles; the long heel needles are the ones that are to be rendered inactive at the
commencement of the heel and toe work and to remain so during said work. To
do this we provide a cam 90 (see Figs. 5 and 6 in connection with Figs. 7, 9, 10
and 16) which travels in a plane entirely below the needle heels during circular
or round and round knitting, but which is adapted to be raised from that plane
when the change to heel and toe work begins. Said cam 90 is secured to a block 91
rising from a segmental plate 92 which normally fits in a correspondingly shaped
space in the flange of the cam web 82, and which is provided with a pin 93 extend-
ing down through the cam ring 70 and through a long tubular bearing 94 depend-
ing from said ring 70. The lower end of the pin 93 is adapted to be acted upon
in a vertical direction by a circular plate 95 within the cup shaped bearing 4, the
means for raising and lowering which at the commencement and end of heel and
toe work respectively will be described hereinafter.
The block 91 and cam 90 are prevented from rotating on the axis of the pin 93,
by the inner edge of the segmental plate 92 which, at all times, is in contact with
the outer side of the cam web 82 (see Fig. 10). By referring to Fig. 6, it will be
seen that the cam 90 is at a distance from the cylinder sufficient to prevent its
operating upon any of the short heels. But when said cam is elevated to the
position shown in Fig. 9, it will elevate the long heel needles from the position
shown at the right of that figure to the position shown at the left of said figure,
thus carrying them out of position to be operated by the draw cams.
The block 91 has also secured to it an arm 96 having the throwing-in cam 97
at the end thereof, located to move in a path close to the cylinder the acting face
of this cam being indicated in Fig. 5 and by dotted lines in Fig. 5. This cam 97
when lowered engages the tops of the long heels and one short heel, as will be
hereinafter described, and said cam, when the block 91 is lowered at the end of
the heel and toe work, sweeps over the long heels and the single short heel and
lowers the needles to position for circular work; that is, trom the position shown
at the left of Fig. 9, to the position shown at the right of that figure. A pin 93
projects from the cam 90 and is engaged by the outer end of a spring 99 the other
end of which is secured to the flange of the cam web 82; said spring arts to depress
the block 91 and cams when permitted by the descent of plate 95 as hereinafter
described.
The mechanism for picking out the needles one by one and restoring them to
activity in reverse order during the narrowing and widening in heel and toe work,
will next be described, reference being had particularly to Figs. 5, 6, 11 to 16
inclusive, and 18.
Mounted on the cam ring 70 and rotating therewith is an arched standard 100,
provided with an offset 101, in which is a vertical bore or recess 102 closed at the
top, as shown in Fig. 14. A plunger 103 is fitted to slide and oscillate on its axis
within said recess and is pressed downward by a spring 104 ccnfined between the
plunger and the top of the recess. To the lower end of this plunger the picking
finger 105 is pivoted, the outer short end or heel 106 of the finger being held
between two springs 107 secured to the standard or off-set (see Fig. 18. These
springs have a tendency to hold the picking finger and the plunger in such position
that the finger is radial to the needle cylinder, but permit these parts to swing
to either side of that position.
The acting end of the picking finger is formed somewhat in the form of an

page_text: equal-armed cross (see Fig. 32) with two vertical lugs 108 and two horizontal
lugs 109 which are adapted to act on the heels of the needles as presently described.
In order that the spring 104 may act to press the picking end of the finger upward,
as shown in Figs. 5 and 14, or downward as shown in Fig. 13, we provide a movable
support or fulcrum therefor, as at 110. This fulcrum 110 consists of a horizontal
arm having a sharp upper edge projecting from an elbow lever 111 pivoted to
the side of the standard off-set 101. The upper arm of the elbow lever 111 is
adapted to be acted upon by either one of the cams 112 fixed to a block 113 that
is vertically movable at one side of the bed as hereinafter described. The cams 112
have no movement other than a vertical one and hence, as the outer end of
lever 111 sweeps around between them, it may come in contact with one or the
other, according to the elevation of the block 113 and the cams, and so cause the
knife-edge fulcrum arm to shift from the position shown in Fig. 13 to that shown
in Fig. 14, or vice versa. The limit of movement of the fulcrum in one direction
is imposed by its coming in contact with the outer side of the standard 100 and
in the other direction by a stop 114 secured to one side of the off-set 101 as shown in
Figs. 5 and 18.
To the feet of the standard 100 is secured a curved plate 115 (see Figs. 6, 13, 14,
and 15) having an opening through which the picker extends. This opening has
two upper oppositely inclined sides or cams 116 and two lower oppositely inclined
sides or cams 117, slots 118 being formed as horizontal continuations of the
opening at the ends of the cams.
The operation of this portion of the machine is as follows:- -When narrowing
is to be commenced at the heel or toe, and after the cam 90 has raised all of the
long heel needles out of action, the block 113 is raised by mechanism hereinafter
described, and the lower cam 112 throws the elbow lever 111 and consequently
the picking finger 105, into the position shown in Fig. 13. At the same time, the
mction of the cam ring is changed from a continuous rotary to a rotary recipro-
cating movement by the means herein before described and during which move-
ment neither cam 90 nor cam 97 performs any function. As one side of the
upper lug 108 of the picker comes in contact with the side of the butt of the first
needle of the remaining series of needles, the end of the picker is stopped (see
Fig. 16). But since the cam ring continues to move, and with it the standard 100
and cam plate 115, one of the lower cams 117 of the plate rides under the finger
and elevates it, thus causing the upper surface of one of the lugs 109 of the picker
to throw that needle up out of action. As the finger finally rides into the slot 118
of the plate 115, the swinging of the finger from a radial to a tangential position
(see dotted lines in Fig. 16) causes the lugs of the finger to leave the butt of that
needle and in the plane ensured by the height of the slot 118. As soon as the
finger leaves said needle, the springs 104 and 107 cause it to assume the position
indicated in Fig. 13 and by the full lines in Fig. 16, ready to engage and elevate
a needle at the other end of the series. To prevent the finger from throwing a
needle too high, a guard 119 (see Figs. 8, 13 and 17) is attached to one of the
guide blocks 88 and is curved in a horizontal plane across the space within which
the picking finger operates, said guard being sufficiently close to the need'e
cylinder to act as a stop for the heels of the needles.
When the needles are to be brought back again into action, one by one, for
widening. the block 113 is lowered by mechanism hereinafter de-cribed and the
upper cam reverses the position of the elbow lever 111, resulting in moving the picker
to the position shown in Figs. 5 and 14. Then th lower lug 103 of the
picker and the under surfaces of the lugs 109 act on the butts of the needles one
by one to depress them, under the influence of the upper cams 116 of the plate 115
in the same manner as has been described in connection with the operation of
elevating the needles. When all of the short heel nue l'es, excert ce at each
end of the series, have been rendered active, the block 91 is lowered and the
first complete rotation of ring 70 causes the cam 97 to throw in all of the elevated
ndles which are the long-heel needles, and the two remaining short

page_text: heel needles, and round and round work
is automatically resumed.
The reason for throwing in the last two fashioning needles simul-
taneously with the long heel needles, is to avoid leaving a small hole in the
fabric each side of the heel. As all of the needles are down now, the picking
finger engages none of the heels for said finger is then in the position shown in
Fig. 5, the block 113 and cams 112 being lowered at this time, as hereinafter
described.
"
The web-holders or sinkers "as they are sometimes termed, which co-operate
with the needles and prevent the lifting of the web by the upward movement of
the needles, and help to draw the stitch, are indicated at 120 (see Figs. 7 and 30
in connection with Figs. 1, 4 and 5). They are supported in radial grooves in a
bed 121 which is secured to the needle cylinder, as by screws 122, said bed having
a horizontal flange 123 which forms the bearing for a ring 124 carrying the cams
for reciprocating the web holders. Said web-holders are or may be of the usual
form at the inner ends, but their outer ends are formed as follows:-Each web-
holder has an upper shoulder 125 adapted to limit the inward movement thereof
by abutting against the outer wall of the bed 121, and a lower shoulder 126 which
is at a greater distance from the point of the web holder than the shoulder 125 in
order to leave a slight space between said shoulder 126 and the outer wall of the
bed. This permits the cams which are carried by the ring 124 to enter said space
easily to withdraw the holder. The outer ends of the web holders are notched,
as at 127, to receive an elastic band 128 which acts on all the web holders to hold
them inward and prevent their being thrown out by centrifugal force. Said
hand preferably consists of an endless coil of fine steel wire.
The cams which are carried by the ring 124 are shown in Fig. 4, in which 129
represents the double-ended cam for engaging the inner sides of the shoulders 126
for moving the web holders outward during either direction of movement of the
ring, and 130 represents the two cams also carried by the ring 124 for engaging
the outer ends of the web holders to retract them, aided by the action of the end-
less spring 128. Secured to the under side of the ring 124 are two blocks 131
the positions of which are indicated by detted lines in Fig. 4 and between which a
striker 132 extends, said striker projecting from a standard 133 (see Fig. 5) which
rises from and rotates or oscillates with the cat ring 70. When the cam ring 70

The latch-guard ring 134 (see Figs. 4 and 5) is adapted to be swung up out of
the way whenever desired, as when placing a new cuff on the needles or to enable
the needles to be more readily examined, without removing it from its support by
the cam ring 70. Said guard ring 134 is formed as the central portion of an arm
or lever 135 pivoted at 136 to the top of the standard 133, any suitable means
being emploved to retain the arm in a substantially upright rosition when raised.
The front end of the arm 135 is adapted to rest. when in operative position, on
the ton of the off-set portion of the standard 100 which is provided with two
upwardly extending late 187 (Figs. 5 and 18) between which the arm 135
is confined. The ten plates 137. in conjunction with the pivotal connection
with standard 133, ensure the retention of the lever or arm 135 and guard ring 131
in proper position during the certion of the munchine.
The yarn changing devices are carried by the lever 135 and are particularly
simple and efficient in construction and option The Unr urther of the

page_text: outer end of the lever or arm 135 is formed with suitable guide ways for two
slides 138 and 138, one having a yarn guide eye 140 at its inner end and an
upwardly projecting pin having a roller 141 at its outer end, and the other slide
having a varn guide ve 142 at its inner end and a downwardly projecting pin
having a roller 143 at its outer end. Each slide is provided with a rigid out-
wardly projecting arm 144 against which the ends of a lever 145 bear. Said
lever 145 is pivoted to the guard-ring arm between the two slides, and hence when
one slide is pushed in, its arm 144 acts through the lever 145 and the other arm 144
to push the other slide out. The inner ends of the slides are provided each with
a raised portion or stop 146 adapted to abut against a fixed stop 147 between the
slides, to limit the outward movement of said slides. Stops 148 are also affixed
to the guard-ring arm to limit the movements of the lever 145. The means for
automatically reversing the positions of the two guide eyes to change the varn
when changing from circular to heel and toe work, will be described presently.
The curved web guide 149 (see Fig. 4) is formed at the outer end of a spring
arm 150 secured to the arm 135 back of the latch ring, as indicated at 151 in
Fig. 5. A recess 152 is formed in the edge of the web guide, said recess having
hooked ends to retain the yarn which is not being knitted, in position for use
again when the next change is made.
Referring now to Figs. 4, 11, and 12, we will describe the means for causing
the yarn guide eves to change nosition:-A plate 1533 is secured to the bed 1 of
the machine and has a vertical sleeve bearing 154 extending over and below said
bed (see Fig. 1). Said bearing is for a lift rod 155, the lower end of which bears
uron and is operated by a lever 156 the control of which will be hereinafter
described. To the unner end of the lift rod is secured a sleeve 157 having an
arm 158 carrying a block 159 to the upper and lower surfaces of which are secured
plates having cam-shaped edges 160. Said cams 160 are so spaced that one or
the other of the rollers 141 and 143 of the yarn changing slides may sweep be-
tween them when no change in the yarn is to be effected. But when the yarn
guide slides are to be shifted from the positions shown in Figs. 4 and 5, the lift
rod 155 is acted upon by the lever 156 to raise the block 159 and bring the lower
can 160 into the path of movement of the roller 143 which. moving over the edge
of said cam, reverses the positions of the guide eyes herein before described.
guide pin 161 rises from the plate 153 and extends through the block 159 to hold
said block and the cams 160 against lateral movement.
A
When the yarn guides are to be shifted back again, the rod 155 is lowered to
normal position and brings the per cam 160 into the path of movement of the
roller 141 of the now projected slide 139, and thus again effect the change of yarn.
The figures of the drawing which have just been referred to, also illustrate the
means for shifting the cams 112 which change the operation of the picking
finger 105 heretofore described. The block 113 carrying the cams 112 is sun-
ported by an arm 162 projecting from a sleeve 163 loosely mounted on the lift
rol 155. The guide pin 161 passes through the arm 162 to steady it as well as
the block 159. A pin 164 projecting from the arm 162 is normally engaged by a
lu 165 carried by a spring 166 the upper end of which is secured to a lug 167
projecting from the arm 158. The side of lug 165 is inclined as at 168 and
below this incline, the lower end of the spring 166 is curved or inclined, as at 169,
under the end of a finger 170 fixed to the plate 158.
To render the operation of this part of the mechanism more clear, it is necessary
to state here what will be more fully described hereinafter, viz., that the cams
which act on the lift rod 155 impart two elevations to it for each narrowing and
widening operation during which time the yarn is changed. The first lift of
the red 155 elevates the block 159 and cams 160 and changes the yarn as above
described. At the same time, through the medium of the spring 166, its lug 165
and the pin 164, the block 113 is elevated and this brings the picking finger into
operation for narrowing as has been hereinbefore described. Of course the timing
of the operation of other parts is such that simultaneously the needles having the

page_text: long heels are thrown out of action and the rotary reciprocating motion of the
knitting cams takes the place of the continuous motion. When the narrowing
is completed, the lift rod 155 is given a short elevation above the plane of the
first, giving to the arm 158 what may be termed a hitch. This is but momentary,
but it serves to draw the curved lower end 169 of the spring 166 upward over, but
not entirely above, the end of the fixed finger 170 which pushes the spring out-
ward sufficiently to carry the lug 165 out from under the pin 164 of the arm 162.
The arm 162 and its block and cams 112 immediately drop and cause the operation
of the picking finger to begin restoring the needles for widening as has been
hereinbefore described. The second elevation or hitch" of the lift rod is for
this purpose only, and the position of the cams 160 is not so changed as to shift
the yarn guides, for the same yarn is used in widening as in narrowing. Simul-
taneously, however, with the resumption of continuous rotary motion of the
knitting cams and the restoration of all the needles to positions of activity, the
lift rod descends to its normal position and the upper cam 160 effects the change
of the yarn to the color and quality preferred for the round and round work and
the inclined lower side 168 of the lug 165 rides down over the pin 164 and then
the lug snaps under said pin. ready for the next operation. The picking finger
is left turned upward, as indicated in Fig. 5, but, there being no needles with
their heels in a plane to be engaged by the said finger, the latter remains out
of operation until the next change as described.
The means for effecting the elevation of the lift rod, and of the plate 95, and
of the needle cylinder, will next be described.
Secured to the shaft 30 at the opposite end thereof from the belt shipping
disk 60, is a disk 171 to which two sets of cams are attached (see Figs. 2, 3, 23, 24
and 25). To this disk are attached two similar plates or ears 172 the operative
edges or surfaces of which are off-set so as to stand some little distance away from
the disk itself (see Fig. 25). Each of these plates or ears is formed with a cam
surface 173, a portion 174 which is concentric with the axis of shaft 30, and a
cam lug 175 near the rear end of the plate.
The lever 156 hereinbefore described, and which operates the lift red, is pivoted
on the shaft 26 and has its front bevelled end 176 in the path of movement of the
cams 173 and 175. The cam 173 imparts the first elevation to the lift rol, while
the cam 175 gives it the second elevation or
"hitch
" before referred to, after
which the end 176 of the lever passes to the short section of plate 172 behind the
cam 175 and at the next advance of the disk it passes off the plate 172 and to
the position shown in Fig. 3.
Rigidly connected with the lever 156 so as to oscillate therewith, is an upwardly
projecting arm 177 having its end formed with two steps 178, 180 connected by an
incline or cani 179 (see Fig. 3). A spring 181 secured to the bearing for the
lever 156 and arm 177 bears against a pin 182 projecting from the arm 177 and
tends to hold said arm and the lever 156 in the position shown in Fig. 3, a
stop 183 projecting from the ring 76 serving to limit the movement of said lever
and arm toward the left in said fig.
The circular plate 95 which, as hereinbefore stated, rises and falls to control
the action of the cams 90 and 97, is secured to a rod 184 which is adapted to slide
vertically through an opening in the cup-shaped bearing 4, and in a guide 185
carried by one of the bars 77. The lower end of the slide rod 184 rests on the
upper end of the arm 177 and as the latter oscillates, passes from step 178 to
ten 180, over the incline 179, or vice versa. The action of these parts is so timed
that the circular plate 95 is elevated to render inactive the needles having the
long heels, simultaneously with the first elevation of the litt rod 155, by cam 173
which, as before stated, causes the change of yarn and the commencement of
operation of the picker finger. But when the lift rod is given its second elevation
(11 hitch" by means of cam lug 176, the step 178 simply moves slightly across
the lower end of the slide rod 184 without affecting the elevation of the circular
plate 95.
**

page_text: The disk 171 carries also two segments 186 each having a cam surface 187 at
one end, adapted to act upon a block 188 carried by a lever 189 pivoted at 190 to
the frame of the machine, and having a lug 191 adapted to bear against the lower
edge of the web-guide 75 when the latter is to be lifted to elevate the needle
cylinder as herein before mentioned. In order to adjust the amount of elevation
that may be imparted to the web-holder and needle cylinder, by the cams, the
block 188 is adjustably connected with the lever 189. As shown in Fig. 3, said
block is carried by a plate spring 192 attached at 193 to the under side of the
lever, a screw 194 being tapped through the lever and bearing on the free end
of said plate spring. As indicated in Figs. 2 and 25, the cam segments 186 are
secured close to the disk 171, so that when the block 188 is not being acted upon
by said segments, it will ride along the edge of said disk.
The needle cylinder 72, as has been stated, rests upon the shoulder 74 of the
web-guide 75 (see Fig. 7). The upper end of the latter is surrounded by the
needle cylinder, and the fit is such that the cylinder could be rotated upon its
seat if not locked. In order to prevent accidents arising from any disarrangement
of the cams carried by the ring 70 relatively to the needles, we provide a yielding
lock for securing the needle cylinder to the upper end of the web-guide. This
lock, as shown in Figs. 7, 27 and 28, consists on a spring bar 195 secured to the
inner wall of the web-guide and having a wedge-shaped lug 196 at its upper end,
which lug extends through an opening in the web-guide and into a tapered
recess 197 in the inner wall of the needle cylinder. The bar 195 may be yielding
throughout its length, but preferably its point of chief elasticity is near the lower
end, as at 198. The upper end of the bar 195 rests in a vertical groove 199 in the
inner wall of the web-guide 75, and said bar and its lug 196 form a lock to prevent
rotation of the needle cylinder on the web-guide. But should a needle ofter an
obstruction to the passage of a cam, or if for that or any other reason such an
obstruction is caused as might break a cam or break away the ribs of the cylinder
between the needles, the inclined side of the recess 197 will act on the side of the
lug 196 and force it inward, thus unlocking the cylinder from its support and
permitting it to rotate. In order that the wedge-shaped lug may be held in its
uccess with greater or less force, the lower end of the bar 195 is formed with a
shoulder or lug 200, and screws 201 pass through the bar above and below said
lug. By loosening one screw and turning in the other, the bar is rocked on its
Lug 200 as a fulcrum and thus forces the lug 196 more or less into the recess of
the needle cylinder.
This automatic or self releasing lock permits the needle cylinder to be turned
readily by hand, whenever it may be desired to remove any needles or sinkers, or
replace them, in a portion of the cylinder that would otherwise be difficult of
access. And this can be done by simply using a little force with the hands in
starting the cylinder around, without removing or replacing any part or pieces of
the machine or frame.
It will be observed also that our construction of the needle cylinder and cams is
such that no casing or other parts require removal in order to give access to needles
or sinkers. It has already been described how the sinkers may be removed, and
it need only be added that any needle may be removed by first pulling it up until
its lower and is above the cam rib 82, and then taking hold of the heel of that
needle and drawing it outward and downward.
One of the yarn bobbins 202 is shown in Fig. 1, as supported on a shelf or
place 203 carried by a bracket 204 attached to the frame of the machine. The other
yarn bobbin 205 is supported in a rotary manner above the needle cylinder, by the
following means; A standard 206 is suitably attached to the frame and is provided
with an arm 207 at its upper end, to the outer end of which arm a bar 208 is
pivotally connected in any suitable manner. From the ends of this bar, two
rods 209 depend and are connected to a circular plate or table 210 at their lower
ends. This table supports the upper bobbin. To steady it, a ring 211 surrounds
the table, said ring being supported at one edge by a sleeve 212 connected to the

page_text: standard 206.
A leg 213 rising from the ring 70 is connected with the table 210 to
rotate the latter and the bobbins thereon during knitting.
The two yarns pass through suitable guides and take up devices. In Fig. 29,
a guide 214 is shown for the yarn from the lower bobbin, another guide, not shown,
being carried at the end of the arm 207. In said Fig. 29, one form of take up
is shown connected to one of the rods 209, said take up consisting of a spring.
operated arm 215 having a suitable eye for the yarn, other eyes for the yarn being
carried by the lower end of an arm 216 carried by said rod 209. The take up,
however, forms no part of our present invention and may be of any well known
or preferred type.
Having described the operation of the several parts of our machine in connec-
tion with the detailed description of the construction thereof, reference to the
general operation will be unnecessary, further than to mention in connection with
Figs. 34 and 35 that the cuff a which, as usual, is knitted on a cuff knitting
machine, is placed on the needles by means of a transferrer, and circular knitting
at 6 proceeds to the point c. Then narrowing begins and continues to the point d
and from there the knitting widens to the point e when circular knitting is con-
tinued to form the foot portion f. At g narrowing again begins and continues
to the point h from whence it again widens to the point i, when, after knitting a
few courses, the machine automatically stops. The operator then breaks off the
yarn and by means of the crank 11 turns cam ring 70 one revolution forward, which
disengages the needles from the stocking so that it may be removed, and then moves
the crank backward slightly which, through the engagement of the heels of the
needles, with the block 85 last in operation forces said block out of operative.
position and permits the corresponding cam 83 to raise the needles so that their
upper ends will be on a level and in position to receive another cuff. After the
stocking has been removed from the machine the edges i and k may be united in
the usual or any preferred manner.
