IMPROVEMENTS IN KNITTING MACHINES
Year: 1885

page_text: I, CHARLES AUBREY DAY of 321 High Holborn in the County of Middlesex,
Fellow of the Institute of patent agents do hereby declare the nature of the
Baid invention for IMPROVEMENTS IN KNITTING MACHINES (a communication to me
from abroad by William Bliss Medlicott of Longfellow, Hampden County and
State of Massachusetts, manufacturer, and James and Walter Bramley of Spring-
field, Hampden County and State of Massachusetts, United States of America, to
be as follows
-
This invention relates to improvements in straight knitting machines, the object
being to provide improved vertical sinkers for receiving the yarn and delivering
the loops to the needles, and improved operating mechanism therefor, whereby the
Jain carrier is operated with such rapidly reciprocating motion as to greatly
increase the production of the machine and the employment of dividing sinkers 18
obviated.
A further object of this invention is to provide improved means for operating
the knocking-over bar, whereby its movements are made positive and it is thereby
adapted to rapid action without derangement, and to provide improved fashioning
devices whereby the latter are caused to act alternately upon each edge of the
fabric while the carrier is performing its work at the opposite edge thereof, and no
time is lost by reason of any dwell of the carrier at each edge, and to provide
improved knitting and fashioning mechanism acting in conjunction, whereby the
yarn is received from the carrier and held while the needle-held loops are being
operated upon by the fashioning tackle
Referring to the drawing, figure 1 sheet 1 is a rear elevation of a single
division of a knitting machine embodying our improvements, (it being understood
that in practice the machine embraces any desired number of divisions), having
the shafts e', and m³, and the lever o, rod ot, crank-disk o³, and the bars g, k, and 4,
partly broken away to more clearly show the parts behind them.

the left-hand end of that figure Figure 3 sheet 2 is a perspective view of the
fashioning-finger holder and its case Figure 4 sheet 18 a perspective view of
said holder, one of said fingers, and the cap securing the latter to the former.

page_text: Figures 5 to 11, inclusive, sheet 3, are diagrams illustrating the action of the
knitting and fashioning devices Figure 12, sheet 3 is a side-view of a cam and
its roller-plate, and of an arm-roller Figure 13, sheet 3 is a full-sized side
elevation of one of the vertical sinkers
In the drawing, A, is the frame of the machine, B is the driving shaft having
thereon suitable driving pulleys, c is a gear on shaft B, d, 18 the cam-shaft, having
gear c¹, thereon engaging with gear c, the can-shaft d, having thereon cams e, f, h,
37, 47, 38, 32, 49, and z, whose functions are hereafter explained
The fashioning rock-shaft 9, is actuated by the cam f, through a suitable
connection with the same by the rod f¹, and an arm f³ on said shaft, to give a
vibratory motion to the fashioning-finger cases 2 The slide bar holders 3 are
secured to shaft g, and the bars 4, slide therein to give a longitudinal motion to the
fashioning-finger cases 2, the latter being attached to bar 4, one on each of the
latter, by screws as shown
The fashioning-fingers 7 have their upper ends bent over at right angles to the
body of the finger and are secured to the finger-holder 5, by engaging then bent
ends in the holes in the holder and securing the plate s, against the fingers as
shown in Figs 3 and 4 The finger-holder 5 is fitted to slide up and down in the
case 2, and 18 given that motion by the engagement therewith of the end of the
lever 6, the end of the latter entering the upper hooked portion of the finger
holder, as in Fig 2 The end of said lever 6, which enters the hooked part of the
holder 5, 18 of sufficient length to permit the finger-holder to have the slight sliding
motion thereon required to permit the fingers 7 to perform their functions in the
usual manner, relative to the fashioning of the edge of the fabric.
The connection of the ends of the slide bars 4 with mechanism for giving them
their sliding motion at the proper time for the fashioning-fingers to operate, 18
together with said mechanism, substantially such as shown in English Patent
No 3820, of December 16, 1868, and said connection is adapted to allow the
points of the fingers 7 to have a slight vibratory motion, actuated by the rock-
shaft g, whereby by their aforesaid vertical, longitudinal and vibratory motions the
fingers take the selvage, lift it off from the needles, move it forward of the sinkers
(then "traversing") and then to put it back on to the needles The selvage 18 80
manipulated because the fashioning is done while the ordinary course is being run,
the operation of each set of fingers (one at each selvage) taking place alternately
and while the yarn-guide is approaching the selvage
In practice the machine is provided at each end with a cam h, and its connections
with shaft k, by rod 2, (one of the arms 6, being on each of the shaft K)
The aforesaid fashioning devices are hung on arms m, m, and the latter are
secured on the rock-shaft m³, at the rear side of the machine The arms m, have
extensions n, bolted to their extremities and reaching over and beyond the needles
and sinkers of the machine A vertical post n³, is secured to each of the
extensions n, the lower end of which engages with a suitable cam on shaft d,
(not shown in the drawing) to give said fashioning parts and the fingers 7, the
requisite, properly timed vertical motion required to lift and drop the selvage of
the fabric
The drawing-arm o, is pivoted by one end to a portion of frame A, and is given
a vibratory motion by its connection with the rotating crank-disk o³, through the
connecting bar o, the swinging-lever o, and the connecting bar o, the latter being
pivotally connected to the said crank-disk by a bolt which is adjustably connected
with a transverse slot in the face of the disk as shown, whereby the vibratory
movement of the drawing-arm o, is varied
The crank-disk o³, 18 secured to the end of a short shaft hung in suitable bearings
on frame A, and on the opposite end of said shaft 18 fixed a bevel gear engaging
with the gear o, on shaft d
The forked upper end of the arm o, engages with a pin 8, on the rear side of the
slur-box 9, giving the latter the requisite motion to carry the usual slur-cock
against the rear ends of the jacks, back and forth.

page_text: The jack-rod 10 prevents the jacks from falling too far back. The slur-bar on
which the box 9 slides is indicated by 11 The Jacks 12 are arranged to act in the
usual manner against the rear ends of the horizontal sinkers 13
The thread-carrier 15 moves in the usual way on the rod 14
The catch-bar 16, 18 connected with the rock-shaft e³, by the arm 18, and the
link 17
The rock-shaft e³, is operated by an arm (shown in dotted lines in Figure 2)
connected thereto, the end of which engages with a cam on shaft d, of suitable form
to give it the usual forward and back movement, and the catch-bar 16, 18 given a
lifting and falling motion by a suitable cam 2, on shaft d, with the catch-bir 18
connected by the vertical rod 20, at the end of the machine in Figure 1 which 18
pivoted to the end of an arm shown in dotted lines in Figure 2, said arm having
one end pivoted to frame A, the arm engaging with said cam
The horizontal sinker-bar 21 is stationary on the machine
To the front side of the jack-bar 22, 19 secured the vertical sinker-bar 23, the
face of which is vertically grooved to receive the rear edges of the vertical
sinkers 25, a side view of one of which, in full size, is shown in Figure 13
The vertical sinkers 25, have a notch 58 in the edge thereof, in which engages a
rib on the inner face of the vertical sunker slide 24, between which and the sinker-
bar 23, the vertical sinkers are supported
Said vertical sinkers 25, (see Figs 2 and 13) are constructed of suitable sheet-
metal, preferably of steel of a thickness substantially equal to the diameter of the
heads of the needles w, directly back of which they operate as hereinafter described,
in conjunction with the horizontal sinkers 13, the needles, the knocking over
bits 44, and the yarn-carier 15
The upper ends of the vertical sinkers which operate between the horizontal
sinkers, and the needles are of a blade form and are wide enough to make them
sufficiently rigid to resist any strain that may be put upon them by the yarn as it
18 doubled around them and drawn against their rear edges when the horizontal
sinkers move towards the needles at the commencement of the formation of the
loops or stitches.
Furthermore, the said form of the vertical sinkers whereby they possess the
aforesaid characteristics, obviates the employment in machines of this class of
dividing sinkers, thereby greatly simplifying the machine
The edges of the said vertical sinkers behind which the yarn is laid by the
carrier, have, just below their point a curved form as shown to facilitate the easy
delivery of the loops over their ends on the needles
The above-described manner of securing the vertical sinkers to the slide 24, and
between the latter and the bar 23, insures the precision of movement and strength
required in machines of this class, and obviates the inconveniences pertaining to
the construction and application of similar devices heretofore employed on knitting
machines, which inconveniences result from weakness of the parts and liability to
break and a tendency to become loose and displaced
The jack-bat 22, the vertical-sinker bar 23, the vertical sinker-slide 24 and the
vertical sinkers 25, all have a to-and fro motion in respect to the length of the
honzontal sinkers 13, and the sinkei-slide 24, and the vertical sinkers 25, have, in
addition to said to and fro motion, a reciprocating vertical motion
The said to and fro motions of the parts 22, 23, 24 and 25, are produced by the
action of a suitable cam 49 (shown in dotted lines in Fig 1) on shaft d, upon an
arm 26, hung on a rock-shaft 27, there being on the latter a suitable number of
vertical arms 28, connected with the jack-bar 22, by the bar 29, as shown in
Figures 1 and 2
The said reciprocating vertical motion is given to the sinker-slide and the vertical
sinkers 25, by an arm 30, on a rock-shaft 31 The arm 30, has one end engaging
with a suitable cam 32, on shaft d, and its opposite end is pivoted with a slot x, in
which a pin in a down-hanging arm v, on the sinker-slide 24 engages
Said pin-

page_text: and-slot connection permits the parts above named to have the said to and fro
motion while being engaged with the arm 30
The needle-bar 33, 1s hung on two arms 34, which are secured on a rock-shaft 35,
the latter having an arm 36, secured to it which engages with a cam 37, on shaft d
whereby said shaft is rocked and the needle-bar and the needles w, are given a
properly timed vertical reciprocating motion
A motion to and from the edge of the horizontal sinker-bar 21, or the presser 18
given to the needle bar 33, by the cam 38, on shaft d, acting on an arm 39. Said
arm has a stud thereon lying against the edge of said cam behind the shaft d,
Fig 2, and therefore said stud does not show in said figure
The arm 39 swings loosely on the shaft 40, between the two collars y, y,
Figure 1
A pendant arm 41 hanging in a line with artn 39, 18 secured to the under side of
the needle bar 33, and to its lower end is pivoted a link 42, having a slot in its
under edge which engages on a pin on the side of the arm 39 (See Figures 1
and 2) Thus when arm 39, swings by its contact with its proper cam on shaft d,
and when link 42 connects arm 39 with the arm 41, the needle-bar 18 given a
rocking motion carrying the needles to and from the "presser," as aforesaid
The knocking-over bar 43, carrying on its edge next to the needles the "bits" 44,
18 hung on two vertically sliding supports 45, attached, one to each end thereof
The said supports are slotted as shown and are hung on the frame A, so that they
permit the knocking-over bar to have a free up and down motion The said
supports 45, have each a pin in the side thereof as shown in Fig 2, with which the
forked end of a lever 46, engages, which lever is secured to a rock-shaft 40 An
arm 48, secured on shaft 40, engages with cam 47, on shaft d, whereby the
knocking-over bar 18 given a vertically reciprocating motion as aforesaid
In this machine the "shogging" of the cam shaft does not stop the drawing
devices as in knitting machines heretofore made, the gear o³, on shaft d, not being
thrown out of connection with the gear on the end of the short shaft which caries
the crank-disk o, when shaft d, is shogged to bring the fashioning cams into
action, which act on bars f1, 2 and n³, for the purpose above-described
«
"
The "shogging" devices, consisting of the cams 50 and 51, and the roller and
arm 52, are substantially of the ordinary description except that they are con-
structed to "shog" the cam-shaft at every half revolution
The shaft d, and the bevel o³, have a splined connection to allow the shaft to
slide endwise while the gear remains stationary and continues to revolve with the
shaft
"
The cams f and h, and the one operating bar n² (the latter not being shown in
the drawing) consist of two plates united side by side, one being of cam-form, and
the other cucular, as shown by the lines in Fig 12, the cam-plate being adapted
to act twice in a revolution At two points on the periphery of the cam the latter
is flush with the edge of the circular plate, and when said flush points arrive
opposite the stud on an arm which the cam actuates, the shaft is " shogged
carrying the cam or the circular plate under the stud, as the action of the machine
may require When the fashioning devices are not required to act the bearing of
said stud is on the said circular plate, but when for fashioning, the shaft d, 18
shogged, the cam-plate is brought to act on the stud It is understood that the
fashioning action takes place at every half revolution of the cam-shaft
The needle-bar cam 38, on which arm 39 bears, 1s a double cam, one part of
which gives to the needle-bar the aforesaid rocking motion, and the other part acts
when the shaft is "shogged" to swing the ends of the needles away from the nibs
of the horizontal sinkers 13, only while the fashioning is going on
The part of cam 47 which is brought under arm 48, when shaft d, 18 " shogged,"
acts to drop the knocking-over bar down out of the way when the fashioning
finger are operating
The part of cam 37, on which arm 36 bears during the fashioning, acts to
"knock over" the work, or in other words, lets it rise immediately to bring it to

page_text: the fashioning-fingers 7, and to carry the needles down with the fashioning fingers,
and then the latter traverse, and following the latter action the needles are brought
against the sides of the fingers so that the stitches can be again delivered to the
needles.
Both of the parts of cam 32 are of the same peripherial form the cam being
so made, of double thickness to allow it to move laterally under the stud on
arm 30
The above-mentioned arms which are acted on by the cams, are provided with
the usual friction rollers 55 as shown, and the rollers are held in contact with their
respective cams by means of the usual tension-springs
The operation of the above-described improvements 18 as follows
At the start of the carrier 15 from one end, the needles have the loops, and the
vertical sinkers are up and the horizontal sinkers are quite back ready to move
forward and strike the loops.
Simultaneously with the start of the carrier the vertical sinkers rise, behind which
the yarn is laid by the carrier, and the horizontal sinkers follows out as the carrier
moves along Then the ends of the needles are carried up close under the hori-
zontal sinkers so that the length of the loop between the ends of the needles and
the throat of the sinker will be short, and thereby the selvage-loop will be drawn
tight and make a good selvage
At half of the traverse of the carrier the heads of the needles swing back from
the vertical sinkers, the needles then moving down carrying the loops they hold
against the knock-over bits 44, delivering the fully formed loops over the heads of
the needles Meanwhile the carrier completes its traverse, the needles rising while
the carrier so moves.
The next movement is that of the catch-bar which comes forward and engages
with the rear ends of the horizontal sinkers, and at this point the vertical sinkers
begin to move down to deliver the loops they hold on to the needles, and as the
vertical sinkers go down, and while their rear curved edges draw out the loops, the
catch-bar moves the horizontal sinkers forward just enough to prevent the loops
from slacking up by reason of the increasing narrowness of the points of the
vertical sinkers After falling the vertical sinkers fall back under the stationary
presser, and then the needles go down catching the loops held by the horizontal
Binkers under their beards and continue to swing down and backwards, their
beards being forced against the presser to close them and so draw the new loops
down through the old ones, and then the horizontal sinkers retire from under
the loops.
The aforesaid action of the heads of the needles relative to the horizontal sinkers,
is provided for so that, after the introduction of the vertical sinker, (the needles
being down in this case instead of up, as in the knitting machines heretofore built)
just as good a selvage shall be formed as is made when the vertical sinker is not
employed
To the slide 5 and box 2, a similar filling up device such as is ordinarily used on
machines of this class may be added.

page_text: I, CHARLES AUBREY DAY of 321 High Holborn in the County of Middlesex,
do hereby declare the nature of the said invention (a communication to me from
abroad by William Bliss Medlicott of Longmeadow, Hampden County & State of
Massachusetts, United States of America, manufacturer and James & Walter
Bramley of Springfield, Hampden County & State of Massachusetts United States
of America) 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 improvements in straight knitting machines, the object
being to provide improved vertical sinkers for receiving the yarn and delivering
the loops to the needles, and improved operating mechanism therefor, whereby the
yarn carrier is operated with such rapidly reciprocating motion as to greatly
mcrease the production of the machine and the employment of dividing sinkers is
obviated.
A further object of this invention is to provide improved means for operating
the knocking-over bar, whereby its movements are made positive and it is thereby
adapted to rapid action without derangement, and to provide improved fashioning
devices whereby the latter are caused to act alternately upon each edge of the
fabric while the carrier is performing its work at the opposite edge thereof, and no
time is lost by reason of any dwell of the carrier at each edge, and to provide
improved knitting and fashioning mechanism acting in conjunction, whereby the
yarn is received from the carrier and held, while the needle-held loops are being
operated upon by the fashioning tackle
Referring to the drawing, figure 1 is a rear elevation of a single division of a
knitting machine embodying our improvements, (it being understood that in
practice the machine embraces any desired number of divisions) having the shafts e³,
and m³, and the lever o, rod o', crank disk o³, and the bars g, k, and 4, partly
broken away to more clearly show the parts behind them
Figure 2 is a vertical section through line x, x figure 1, looking from the left-
hand end of that figure Figure 3 is a perspective view of the fashioning-finger
holder and its case Figure 4 18 a perspective view of said holder, one of said
fingers, and the cap securing the latter to the former Figures 5 to 11, inclusive,
are diagrams illustrating the action of the knitting and fashioning devices

In the drawing, A, is the frame of the machine, B 18 the driving shaft having
thereon suitable driving pulleys, c is a gear on shaft B, d, is the cam shaft,
having gear c¹, thereon engaging with gear c, the cam-shaft d, having thereon
cams e, f, h, 37, 47, 38, 32, 49, and s, whose functions are hereafter explained.

page_text: The fashioning rock-shaft g, 18 actuated by the cam 17, through a suitable con-
nection with the same by the rod f¹, and an arm f³ on said shaft, to give a
vibratory motion to the fashioning finger cases 2 The slide-bar holders 3 are
secured to shaft g, and the bars 4, slide therein to give a longitudinal motion to
the fashioning finger cases 2, the latter being attached to bars 4, one on each of
the latter, by screws as shown
The fashioning-fingers 7 have their upper ends bent over at right angles to the
body of the finger and are secured to the finger-holder 5, by engaging their bent ends
in the holes in the holder and securing the plate 8, against the fingers as shown in
Figs 3 and 4 The finger-holder 5 18 fitted to slide up and down in the case 2, and
is given that motion by the engagement therewith of the end of the lever 6, the
end of the latter entering the upper hooked portion of the finger-holder, as in
Fig 2 The end of said lever 6, which enters the hooked part of the holder 5, 1s
of sufficient length to permit the finger-holder to have the slight sliding motion
thereon required to permit the fingers 7 to perform their functions in the usual
manner, relative to the fashioning of the edge of the fabric
The connection of the ends of the slide bars 4 with mechanism for giving them
their sliding motion at the proper time for the fashioning-fingers to operate 18,
together with said mechanism, substantially such as shown in English Patent
No 3820, of December 16, 1868, and said connection 18 adapted to allow the
points of the fingers 7 to have a slight vibratory motion, actuated by the rock
shaft g, whereby by their aforesaid vertical, longitudinal and vibratory motions
the fingers take the selvage, lift it off from the needles, move it forward of the
sinkers (then "traversing") and then to put it back on to the needles The
selvage is so manipulated because the fashioning is done while the ordinary course
18 being run, the operation of each set of fingers (one at each selvage) taking place
alternately and while the yarn-guide is approaching the selvage
In practice the machine is provided at each end with a cam h, and its connections
with shaft k, by rod 2, (one of the arms 6, being on each of the shafts K )
The aforesaid fashioning devices are hung on arms m, m, and the latter are
secured on the rock-shaft m³, at the rear side of the machine. The arms m, have
extensions n, bolted to their extremities and reaching over and beyond the needles
and sinkers of the machine A vertical post n³, 18 secured to each of the exten-
SIODs n, the lower end of which engages with a suitable cam on shaft d, (not
shown in the drawing) to give said fashioning parts and the fingers 7, the
requisite, properly-timed vertical motion required to lift and drop the selvage of
the fabric
'
The drawing-arm 0, 18 pivoted by one end to a portion of frame A, and is given
a vibratory motion by its connection with the rotating crank-disk o³, through the
connecting bar o, the swinging-lever o³, and the connecting bar o, the latter being
pivotally connected to the said crank-disk by a belt which is adjustably connected
with a transverse slot in the face of the disk as shown, whereby the vibratory
movement of the drawing-arm o, 18 varied.
The crank-disk o³, is secured to the end of a short shaft hung in suitable bearings
on frame A, and on the opposite end of said shaft is fixed a bevel-gear engaging
with the gear o³, on shaft d
The forked upper end of the arm o, engages with a pin 8, on the rear side of the
slur-box 9, giving the latter the requisite motion to carry the usual slur-cock
against the rear ends of the jacks, back and forth
The jack-rod 10 prevents the jacks from falling too far back
The slur-bar on

The rock-shaft e³, 18 operated by an arm (shown in dotted lines in Figure 2)
connected thereto, the end of which engages with a cam on shaft d, of suitable

page_text: form to give it the usurt forward and back movement, and the catch bar 16, 18
given a lifting and falling motion by a suitable cim z, on shaft d, with which the
catch-bar 18 connected by the vertical rod 20, at the end of the machine in Figure 1
which 18 pivoted to the end of an arm shown in dotted lines in Figure 2, said arm
having one end pivoted to frame A, the arm engaging with said cam.
The horizontal sinker-bar 21 18 stationary on the machine
To the front side of the jack-bar 22, is secured the vertical sinker-bar 23, the
face of which is vertically grooved to receive the rear edges of the vertical
sinkers 25, a side view of one of which, in full size, 18 shown in Figure 13
The vertical sinkers 25, have a notch 58 in the edge thereof, in which engages
a rib on the inner face of the vertical sanker alde 24, between which and the
sinker-bar 23, the vertical sinkers are supported.
Said vertical sinkers 25, (see Figs 2 and 13,) are constructed of suitable sheet-
metal, preferably of steel, of a thickness substantially equal to the diameter of the
heads of the needles w, directly back of which they operate as hereinafter described,
in conjunction with the horizontal sinkers 13, the needles, the knocking-over bits 44,
and the yarn-carrier 15
The upper-ends of the vertical sinkers which operate between the horizontal
sinkers, and the needles are of a blade form and are wide enough to make them
sufficiently rigid to resist any strain that may be put upon them by the yarn as it is
doubled around them and drawn against their rear edges when the horizontal sinkers
move towards the needles at the commencement of the formation of the loops or
stitches Furthermore, the said form of the vertical sinkers whereby they possess
the aforesaid characteristics, obviates the employment in machines of this class of
dividing sinkers, thereby greatly simplifying the machine
The edges of the said vertical sinkers behind which the yarn is laid by the
carrier, have, just below their points, a curved form as shown, to facilitate the
easy delivery of the loops over their ends on to the needles
The above described manner of securing the vertical sinkers to the slide 24, and
between the latter and the bar 23, insures the precision of movement and strength
required in machines of this class, and obviates the inconveniences pertaining to
the construction and application of similar devices heretofore employed on knitting
machines, which inconveniences result from weakness of the parts and liability to
break and a tendency to become loose and displaced
The jack-bar 22, the vertical-sinker bar 23, the vertical sinker-slide 24 and the
vertical sinkers 20, all have a to-and-fro motion in respect to the length of the
horizontal sinkers 13, and the sinker-slide 24, and the vertical sinkers 25, have,
in addition to said to and fro motion, a reciprocating vertical motion
The said to and fro motions of the parts 22, 23, 24 and 25, are produced by the
action of a suitable cam 49 (shown in dotted lines in Fig 1) on shaft d, upon an
arm 26, hung on a rock-shaft 27, there being on the latter a suitable number of
vertical arms 28, connected with the jack-bar 22, by the bar 29, as shown in
Figures 1 and 2
The said reciprocating vertical motion is given to the sinker-slide and the
vertical sinkers 25, by an arm 30, on a rock-shaft 31 The arm 30, has one end
engaging with a suitable cam 32, on shaft d, and its opposite end is pivoted with
a slot x, in which a pin in a down hanging arm v, on the sunker-slide 24, engages
Said pin-and-slot connection permits the parts above named to have the said to
and fro motion while being engaged with the arm 30.
The needle-bar 33, is hung on two arms 34, which are secured on a rock-shaft 35,
the latter having an arm 36, secured to it which engages with a cam 37, on
shaft d, whereby said shaft is rocked and the needle-bar and the needles w, are
given a properly-timed vertical reciprocating motion.
A motion to and from the edge of the horizontal sinker-bar 21, or the presser,
is given to the needle-bar 33, by the cam 38, on shaft d, acting on an arm 39
Said arm has a stud thereon lying against the edge of said cam behind the shaft d,
Fig 2, and therefore said stud does not show in said figure,
ว

page_text: The arm 39 swings loosely on the shaft 40, between the two-collars y, y,

A pendant arm 41 hanging on a line with arm 39, is secured to the under side
of the needle-bar 33, and to its lower end is pivoted a link 42, having a slot in
its under edge which engages on a pin on the side of the arm 39 (See Figures
1 and 2) Thus when arm 39, swings by its contact with its proper cam on
shaft d, and when link 42 connects arm 39 with the arm 41, the needle-bar

end thereof The said supports are slotted as shown and are hung on the frame A,
so that they permit the knocking over bar to have a free up and down motion
The said supports 45, have each a pin in the side thereof as shown in Figure 2,
with which the forked end of a lever 46, engages, which lever is secured to a
rock-shaft 40 An arm 48, secured on shaft 40, engages with cam 47, on shaft d,
whereby the knocking-over bar is given a vertically reciprocating motion as
aforesaid
In this machine the "shogging" of the cam shaft does not stop the drawing
devices as in knitting machines heretofore made, the gear o³, on shaft d, not being
thrown out of connection with the gear on the end of the short shaft which carries
the crank-disk o³, when shaft d, 18 "shogged" to bring the fashioning cams into
action, which act on bars f1, 2, and n², for the purpose above-described
The "shogging" devices, consusting of the cains 50 and 51, and the roller and
arm 52, are substantially of the ordinary description except that they are con-
structed to "shog" the cam-shaft at every half revolution
The shaft d, and the bevel gear o³, have a splined connection to allow the shaft
to slide endwise while the gear remains stationary and continues to revolve with
the shaft.
"
The cams f and h, and the one operating bar n', (the latter not being shown in
the drawing) consist of two plates united side by side, one being of cam-form, and
the other circular, as shown by the lines in Fig 12, the cam plate being adapted
to act twice in a revolution At two points on the periphery of the cam the latter
18 flush with the edge of the circular plate, and when said flush points arrive
opposite the stud on an arm which the cam actuates, the shaft is shogged",
carrying the cam or the circular plate under the stud, as the action of the machine
may require When the fashioning devices are not required to act the bearing of
said stud is on the said circular plate, but when, for fashioning, the shaft d, 18
shogged, the cam-plate is brought to act on the stud It is understood that the
fashioning action takes place at every half revolution of the cam-shaft
The needle-bar cam 38, on which arm 39 bears, 18 a double cam, one part of
which gives to the needle-bar the aforesaid rocking motion, and the other part
acts when the shaft is "shogged" to swing the ends of the needles away from the
nibs of the horizontal sinkers 13, only while the fashioning is going on
The part of cam 47 which is brought under arm 48, when shaft d, is "shogged,"
acts to drop the knocking-over bar down out of the way when the fashioning-
fingers are operating
The part of cam 37, on which arm 36 bears during the fashioning, acts to
"knock over" the work, or in other words, lets it rise immediately to bring it to
the fashioning-fingers 7, and to carry the needles down with the fashioning
fingers, and then the latter traverse, and following the latter action the needles are
brought agamst the sides of the fingers so that the stitches can be again delivered
to the needles
Both of the parts of cam 32 are of the same peripherial form, the cam being
so made, of double thickness to allow it to move laterally under the stud on
arm 30

page_text: The above-mentioned arms which are acted on by the cams, are provided with
the usual friction rollers 55 as shown, and the rollers are held in contact with their
respective cams by means of the usual tension-springs.
The operation of the above described improvements is as follows
At the start of the carrier 15 from one end, the needles have the loops, and the
vertical sinkers are up, and the horizontal sinkers are quite back ready to move
forward and strike the loops
Simultaneously with the start of the carrier the vertical sinkers rise, behind
which the yarn is laid by the carrier, and the horizontal sinkers follow out as the
carrier moves along Then the ends of the needles are carried up close under the
horizontal sinkers so that the length of the loop between the ends of the needles
and the throat of the sinker will be short, and thereby the selvage loop will be
drawn tight and make a good selvage.
At half of the traverse of the carrier the heads of the needles swing back from
the vertical sinkers, the needles then moving down carrying the loops they hold
against the knock-over bits 44, delivering the fully formed loops over the heads of
the needles Meanwhile the carrier completes its traverse, the needles rising while
the carrier so moves
The next movement is that of the catch-bar which comes forward and engages
with the rear ends of the horizontal sinkers, and at this point the vertical sinkers
begin to move down to deliver the loops they hold on to the needles, and as the
vertical sinkers go down, and while their rear curved edges draw out the loops,
the catch-bar moves the horizontal sinkers forward just enough to prevent the
loops from slacking up by reason of the increasing narrowness of the points of
the vertical sinkers After falling the vertical sinkers fall back under the
stationary presser, and then the needles go down, catching the loops held by the
horizontal sinkers under their beards and continue to swing down and backward,
their beards being forced against the presser to close them and so draw the new
loops down through the old ones, and then the horizontal sinkers retire from under
the loops
The aforesaid action of the heads of the needles relative to the horizontal sinkers,
18 provided for so that, after the introduction of the vertical sınker, (the needles
being down in this case instead of up as in the knitting machines heretofore built)
Just as good a selvage shall be formed as is made when the vertical sinket is not
employed
To the slide
and box 2, a similar filling up device such as 18 ordinarily used on
machines of this class may be added.
