Improvements in Circular Spring Needle Rib Top Knitting Machines
I, DANIEL HURLEY, of Bennington, in the County of Bennington and State of
Vermont, United States of America, Machinist, 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:-
My invention relates to that class of circular knitting machines in which
double cylinders are used with spring needles in each cylinder and has for its
object to produce a welt which serves as a finish on the end of cuffs, drawer
bottoms, bottoms for shirts, tops of socks and for such other purposes as desired,
which is produced by a certain system of pattern wheels operating pawls and
levers that act upon other levers, cams and pressers to shorten the stitch and
throw the needles of the upper cylinder out of action until the welt is knitted
when the upper needles are again brought into use, doubling the knitted welt over
upon itself and joining it to the body of the fabric, and my invention consists
in the construction and details of parts hereinafter described and more particu-
larly pointed out in the claims.
Heretofore welts have been made on a straight rib machine, and also a very
inferior welt has been made with a latch needle on a circular rib machine: but
there is great objection to the use of the latch needle in making welts as the
stitches are required to be drawn very tight, and as cach needle draws its own
loop, the strain in drawing the yarn through several needles at one time causes
frequent breakage of the yarn, or it is knitted very loose, unless it is very strong
and at the same time removes the elasticity from the yarn and renders the fabric
non-elastic and less desirable on that account, and in tender yarn the strain is
so great as to frequently cause holes to be produced in the fabric, while in the
use of spring needles the loop is put in with a sinker wheel and stitch former
and is then left loose in the head of the needle until it is pressed, when the
needles are carried down just far enough to cast off without putting strain on
the yarn, and by this process with the spring needle, all of the before named
objections to the latch needles are overcome, and a welt is made on my circular
spring needle machine even finer and as perfect, and out of the same degree of
fineness of yarn, as that heretofore made on the straight rib or flat machine.

Like numerals indicate corresponding parts in each figure of the drawing.
1 indicates the frame on which the machine is mounted and 2 the bed resting
on the frame, and 3 the lower cylinder seated in the bed. 4 represents a ring
plate which is properly secured to brackets 5 on the frame above the bed, and
in this ring plate 4 is seated the upper cylinder 6. The cylinders 3 and 6 are
conical in shape, the lower one extending upward and outward from the bed 2,
while the upper one extends downward and outward from the ring plate 4. The
two cylinders are arranged to come within a short space of each other, and each
is provided with the usual spring needles 7, and they are made to revolve
uniformly one with the other by means of any well known power.
The upper inner side of the cylinder 6, is provided with a stand 8 which has
arranged therein a series of movable shipping pins which are adapted to come
in contact with and operate on a series of levers as hereinafter described.
On the inner side of the stand S there is a cam 9 which revolves with the
stand on the cylinder. At each revolution of the cylinder the cam 9 comes in
contact with a roller 10 secured to the lower end of an arm 11 which projects
upwards and backward and is adjustably attached to a rock shaft 12 which has
its bearings in a bracket 13 secured to one side of the frame 1, above the
bracket 5.

page_text: In the rear of the frame there is attached to the rock shaft 12 an adjustable
stop 14 which has a bent arm 15 projecting upwards and forward over the base
of the bracket 13 and is provided in its end with an adjustable screw bolt 16,
which controls the limit of the downward movement of the arm 11 by engaging
the upper edge of the bracket 13.
On the outer end of the rock shaft 12 there is rigidly secured a downwardly
extending arm 17 having in its lower end a lateral journal 18, on the outer end
of which there is pivotally connected a pawl 19. This pawl operates in a ratchet 20
rigidly secured on the side of the regular pattern wheel 21 and revolves the
pattern wheel one notch at each revolution of the cylinders 3 and 6. The pattern
wheel has sprockets 22 on its periphery over which a link belting chain 23 is
fitted and revolves with it. This chain may be of any desired length in accord-
auce with the pattern of work to be made, and one or more of the links are made
to form a cam 24 for starting the movement of a second pattern wheel at proper
times, after said second pattern wheel has been stopped in the manner hereinafter
described.
To the rear of frame 1 beneath the bracket 5 there is attached a bracket 25,
as shown in Fig. 2 which extends outward and has a bearing 26 on its outer end,
through which passes a journal 27. The outer end of this journal has a lever 28
adjustably secured thereto, which works over the chain 23 and comes in contact
with the cam link 24 which raises the lever and thereby operates to move an
arm 29 on the inner end of the journal 27, to change the stitch as hereinafter
described.
The arm 29 is adjustably secured to the inner end of the journal 27, and
extends upwards to about the same height as the lever 28, and has loosely pivoted
to its upper end a lever 30 which is raised on screw head projections 42 on a
pattern wheel 31 for the purpose of stopping said wheel while making the desired
lengths of the different kinds of knitted fabric.
At the side of the vertical arm 29 there is a lateral arm 32 holding a coil
spring 33 which acts to draw the lever 28 and arm 29 towards the pattern
wheels 21 and 31 and keep them down to their work. There is also secured to
the side of the arm 29 a lateral arm 34 extending inwardly, in which there is
an adjustable screw 35 that comes in contact with the vertical stop 36 that is
attached to the main portion of the bracket 25, for the purpose of limiting the
forward movement of the lever 28 to prevent its coming in contact with and rest-
ing on the link belt chain 23, except at such times as it is intended to be raised
by the cam link 24 for the purpose of throwing back the lever 30 from off the
screw pins 42 in the holes 41 in starting the pattern wheel 31 in making the loose
stitch, the welt, the royal rib, or the regular work when the said wheel has been
stopped while making the royal rib. An arm 37 is attached to the side of the
stop 36, which projects forward between the ratchet 20 and pattern wheel 31
and is bent on its inner end to form a hook for holding one end of the coil
spring 33.
On the inner end of the lateral journal 18 of the arm 17 is loosely mounted a
pawl 38 which operates in a ratchet 39 that is located near the center of the
pattern wheel 31. The pawl 38 is provided with a pin 40 in one side, and is
regulated in its action on the ratchet of the pattern wheel by the lever 30 extend-
ing from the vertical arm 29.
The pattern wheel 31 operates to change the stitches, in making that which
is known as the welt, the royal rib, the loose course or in returning to the regular
work, and for the purpose of accomplishing each of these objects a series of screw
holes are placed in the periphery of the pattern wheel opposite the seat of each
tooth of the ratchet. The series of screw holes 41, placed on one side of the
ratchet 39, is provided with stop screws 42 inserted therein at such points as it
is desired to stop the pattern wheel 31. In this operation, as the wheel 31
revolves, the lever 30 is drawn up on the screw head or projections 42, and, as
it is raised, the upper projecting part comes in contact with the lateral pin 40

page_text: in the side of pawl 38 and raises the said pawl out of the ratchet and stops the
action of the pattern wheel.
A second series of screw holes 43 encircle the pattern wheel 31 next to and on
In this series of
the other side of the bracket 39 from the first series 41.

holes 43, screw pins 44. are inserted at such points as is desired for the purpose
of lifting the end of a lever 52 in making a loose course in the work, and a
third series of screw holes 45 encircle the wheel, next to holes 43, in which screw
pins 46 are inserted at proper intervals for raising a lever 62 as the wheel
revolves in making the royal rib in the work, and a fourth series of screw holes 47
encircle the wheel on its inner periphery for screw pins 48 placed at desired
intervals for raising a lever 69 for the purpose of making the welt or rib tops
for socks, anklets for drawers, shirt borders and cuffs.
In the rear of bracket 5, there is attached to the frame a bracket 49 having
double bearings 50 in which three journals are supported, one above the other.
The upper journal 51 carries the lever 52 which is rigidly secured to its outer
end and extends forward over the series of holes 43 in the pattern wheel 31 and
when the pattern wheel is turned operates on the screw pins 44 inserted therein
for making the loose or slack course. On the inner end of the journal 51 there
is rigidly secured a lever 53 that extends forward over the bracket 5 and is
pivotally attached to a link 54 that extends backward and upward and is pivoted
to an arm 55 that is rigidly secured to a shaft 56, that is supported in a double
bearing bracket 57 that is attached to the bracket 5. On the inner end of the
shaft 56 there is a switch plate 58, projecting forwardly and laterally therefrom,
and when the shaft is turned axially the free edge of the plate, parallel with
the shaft, will work up or down between stops 59, formed on a plate 60 screwed
to one edge of the bracket 57, and such stops will limit the movement of the
plate.
To the outer end of the middle journal 61 supported in the bracket 49 is
secured the lever 62 that extends forward over the holes 45 in the pattern
wheel 31, and as the wheel is revolved for making the royal rib stitch the lever
is drawn up on the screw pins 46 inserted in the holes.

to a
On the inner end of the journal 61 there is secured a lever 63 that extends
forward and is pivotally attached to a link 64 that projects backward and upward
and is pivotally attached
an arm 65 that is rigidly secured
shaft 66. This shaft is supported in the middle bearings of bracket 57 and on
its inner end there is a switch plate 67 arranged to operate in the same manner
as the switch plate 58.
To the outer end of the lower journal 68 is rigidly attached the lever 69 which
projects over the holes 47 in the pattern wheel 31 and as the wheel is revolved
for making the welt, the lever is drawn up on the screw pins 48 which is inserted
in the holes. On the inner end of the journal 68 there is rigidly attached a
lever 70 that extends forward, and is pivotally attached to a link 71. This link
extends rearwardly and upwardly and is pivotally connected to an arm 72 that
is rigidly secured to shaft 73 which is supported in the lower bearings of
bracket 57 and on the inner end of this shaft there is also a switch plate 74
arranged to operate in the same manner as the switch plates 58 and 67.
The stand which is rigidly attached to the inner side of the upper cylinder
and made to revolve with it, has therein three series of shipping pins for
operating on and changing levers in producing the different stitches desired in
making the various kinds of work on the machine.
Each series of pins is arranged on a movable slide 116 and these slides work up
and down in grooves 75 in the stand. The upper pins of the three series are
adapted to be respectively engaged by the switch plates 58, 67 and 74 and these
plates being inclined, said pins will be moved positively up or down, according to
the direction of the inclination of the plates and such inclination will be changed
by the axial turning of the shafts 56, 66 and 73 respectively, and the lower pin
of the three series will thus be moved into or out of operative position to

page_text: accomplish the purposes hereinafter described. On the rear of the stand there
are three flat springs 76, each having a projecting point 77 extending through
the back and adapted to engage in one or the other of a pair of depressions 78
in the respective slides, as shown in Fig. 7, for the purpose of holding said slides
in elevated or depressed positions after the switch plates pass out of engagement
with the pins. The front plate 79 of the stand is provided with a series of.
slots 80 through which the shifting pins project.
Each vertical series of slots in the plate 79 is arranged at an angle of about
forty-five degrees to the other series for the purpose of adjusting the pins at
different heights. When these pins are lowered to the bottom of the slots, the
machine is then adjusted for making its regular work. The shipping pins 8.1
are adjusted to the upper extremity of their slots for the purpose of bringing
the lower pin 81 in contact with certain levers for changing the stitch from the
regular work to that of the loose course, and the shipping pins 82, are adjustable
to the upper part of their slots for the purpose of bringing the lower pin 82 in
contact with certain levers for changing the stitch from the regular work to
that of the royal rib, and the shipping pins 8:3 are adjusted to
upper part of their slots for the purpose of bringing the lower pin 93 in line
with other certain levers for the purpose of changing the stitch from the regular
work to that of making the welt.
the
As shown best in Fig. 8, the series of levers upon which the adjustable pins of
the stand 8 are made to operate at such times as is desired to change the stitch
during the revolutions of the cylinders, are arranged at different points on the
ring plate 4 of the upper needle cylinder 6. These levers are arranged in pairs
and are all constructed and operated substantially on the same plan.
The
As shown Figs. 1, 8, and 9 and detailed in Fig. 15 it will be seen that one
pair of these levers are attached to a slotted bracket 84, which is secured to the
bracket 5 before described. The lever 85 is pivoted at 86 to the rear of said
plate while the other lever 87 is pivoted at 88 to the front of the plate.
bracket plate 84 has a slot 89 therein extending at right angles to the length of
the levers, and the lever 87 has two laterally projecting pins 90, which are
separated by a short space, that project into said slot, and the levar 85 on the
other side of the bracket plate has a single projecting pin 91 in the center of
its width, which also extends into the slot and is seated between the pins 90
of the lever 87. The forward end of said lever is formed to provide a cam which
when said lever is in its normal position engages a pin 92 projecting from a
pivoted arm 93 and thereby holds said arm in its forward position, as hereinafter
more fully stated.
In this arrangement of levers in pairs, it will be readily understood that when
the arm of the lever 85 is carried forward by the shipping pins 83 in the stand 8,
the front end of the lever 87 will be thrown forward and released from the pin 92
and the levers will remain in this position until the shipping pin in the stand
is adjusted to come in contact with the arm of the lever 87, when it will be
thrown forward into engagement with the pin 92 and operate thereon to force
the lever arm 93 back and into its original position.
As above stated, the pin 92 projects from the upper surface of a lever arm 93,
one end of which is pivotally attached to the top of the ring plate 4 of the upper
cylinder, while the other end extends loosely back over the edge of the ring and
rests against the up turned end 94 of an angle lever 95 which is pivoted in a
depending bracket 96 that is rigidly secured to the top of the ring. The lower
arm 97 of the lever 95 extends backward beneath the ring plate and is loosely
connected with the end of a link 98. The other end of the link is rigidly secured
at one end of a journal 99 that has its bearing in a stationary cam 100, and on
the other end of the journal there is attached a movable cam 101 which is thrown
up by the operation of said lever 85 for the purpose of enabling the neeilles
to remain elevated on the upper cylinder and leave them out of engagement with
the lower needles while passing through the feed in making the welt. The

page_text: cam 101 18 depressed by the lever 87 after the welt is made, to bring the needles
back into their operative position for the regular work.
On the upper side of the ring plate 4, as shown in Fig. 1, 8, 11 and 12, an
angle bracket 102 is attached which extends upwards and has a lateral slotted
plate 103 that supports another pair of levers constructed and arranged sub-
stantially the same as those hereinbefore described. The lower lever 104 is
pivoted to the underside of the slotted plate 103 while the upper lever 105 is
pivoted to the upper side of the plate. Both of these levers are operated by the
shipping pin 83 the same as the levers 85 and 87 before described, when the
machine is making the welt. The cam operated by the levers 104 and 105 as
hereinafter described, in making the welt is also operated for the purpose of
changing the regular stitch to a loose course, and when so operated it must be
without operating the cam 101 and in order to accomplish this a supplemental
lever 106 is rigidly secured to the front end of lever 105 in position to be operated
by the elevated lower shipping pin 81, without bringing into action the lower
shipping pin, 83 that operates the levers 85 and 87, when it is elevated.
An arm 107 is loosely pivoted at one end on the upper surface of the ring
plate 4, while the other end extends loosely over the front edge of the ring plate
in front and beyond the levers 104 and 105. A vertical pin 108 is in the arm in
front of the levers, and when the shipping pin 83 is brought in contact with the
arm of the lower lever 104, the outer end of the lever is turned and comes in
contact with the pin 108 pressing the arm 107 forward and carrying with it a
right angled arm 109 which projects above the ring. This arm is pivoted to
a bracket 110 extending downward from the top of the ring while its lower
arm 111 extends inward beneath the ring and is loosely connected at one end of
a link 112, while the other end of the link is rigidly secured to a pintle 113,
which has its bearing in a stationary cam 114. The other end of the pintle has
rigidly secured thereto a movable cam 115 which is in its depressed position as
shown in Fig. 12 when the levers 104 and 105 occupy the position shown in
Fig. 8, and the cam 115 is firmly maintained in such position as long as the
lever 104 engages the pin 108 and holds the arm 107 forward. When in this
position the cam 115 acts on the needles in the upper cylinder to depress them in
the usual manner to do regular work. When, however, it is necessary to make
a loose course, or welt, the cam 115 must be raised and this is accomplished by
the lower shipping pin 81 engaging the lever 106, or the lower shipping
pin 83, the lever 105 as the case
the lever 104 from the pin 108 when the cam will be free to be moved
may be, and thereby disengage
up by the needles and the latter will remain elevated and out of engagement
with the needles of the lower cylinder.
When the lower elevated shipping pin 81 is carried around by the cylinder
until it reaches a point opposite the bracket 57 after operating on the lever 106
to raise the cam 115, the switch plate 58 in its normal included position comes
in contact with the upper pin 81 and presses it down as the pin passes under the
plate, when the pin assumes its original depressed position with the other pins
for making the regular work and when the lower shipping pin 83 comes in con-
tact with the lower lever 104 the cam 115 will be again depressed, throwing the
needles of the upper cylinder down at this point where they will again engage
in making the regular work until the switch plates have changed the shipping
pins to operate on levers for making the welt.
Another vertical bracket 117, is attached to the upper surface of the ring
plate 4, as seen in Figs. 1, 8, and 19, and is provided with an upper lateral slotted
plate 118 and a lower lateral plate 119. Each of these plates has a pair of
levers which are constructed to operate upon each other in substantially the same
manner as those herein before described and shown in Figs. 15 and 16.
The lower set of levers 120 and 121 are secured to the plate 119 of the bracket
and are used through a system of arms for pressing the needles into the stitch
wheel for lengthening the stitch in making the regular work, and for with-

page_text: drawing the needles and shortening the stitch in making the welt. When the
needles are pressed into the stitch wheel by the lower levers for making the
regular work, the upper set of levers 122 and 123 may be brought into action
and the connecting arms forced out still further, thereby pressing the needles
further into the stitch wheel and lengthening the stitch for the purpose of making
the loose course.
With this object in view a swinging arm 124 is loosely pivoted to the ring
plate 4 at one side of the bracket 117, and is extended to the front of the bracket
where it has a depending arm 125 holding an adjustable screw 126 that works
against the ring plate 4. To the upper side of the arm 124, and immediately in
front of the levers, there is a vertical standard 127 that is rigidly attached to
the arm by a foot piece 128. This standard extends above the upper pair of
levers and has therein two adjusting pins. The lower pin 129 extends through
the standard and is adapted for adjustment and to be operated on by the end of
the lever 120 to throw the stand outward. The upper piu 130 passes through
the standard near its upper end and is adjustable in or out, and is adapted to
be operated on by the end of the upper lever 122, to throw the standard 127
outward still further than by the lower lever 120, as is desired in making the
loose stitch or course.
A bracket 131 is attached to the underside of the ring plate below the levers
and has a sliding arm 132 working in ways therein. To the front end of said
arm there is rigidly attached an arm 133 having its front end 134 bent upwards
in front of the depending arm 125, and an adjusting screw 135 in the upwardly
projecting part thereof that comes in contact with and works on the side of the
lower portion of the arm 125 in regulating the depth of the stitches made.
A retaining plate 136 is secured to the under side of the bracket 131, over the
guide ways 137 for holding the sliding arm 132 in position. The plate 136 has
a slot 138 near its front end through which a pin 139 projects, which is secured
in the sliding arm 132.
One end of a coil spring 140 is attached to the rear and of the retaining
plate 136 and the other end of the spring is secured to the pin 139 for the pur-
pose of forcing the sliding arm 132 back to the limit of the slot in which the
pin is made to operate, and thereby carry with it the arm 133, the swinging
arm 124 and the vertical standard 127, when the levers are moved off from
the pins 129 and 130.
The sliding arm 132 has on its rear end a downwardly projecting arm 141,
which has a groove 142 therein, in which is placed an adjusting slide 143 which
is held in raised or lowered position by means of the screw in the slot 144. The
slide 143 has a forwardly projecting arm 145 near its lower end to which is
pivotally connected a downwardly extending arm 146 having an adjusting
screw 147 therein for moving the arm forward toward the needles or back from
them as desired, and to the lower end of this arm there is a foot piece 148 stand-
ing at right angles to the arm, and having a serrated edge for pressing the
needles into the stitch wheel 149, as they are forced up by the cam 150 under
the coil springs 131 which holds them on the cylinders.
By this arrangements of parts it will readily be seen that when the levers 120
and 122 are not pressed against the adjusting pins 129 and 130, the coil spring 140.
will operate to draw the arms 133 and 124, and the standard 127 back towards
the ring plate 4, and with them carry back the arms 141 and 146 together with
the foot piece 148, and thereby partially release the needles 7 from the stitch
wheel 149 for the purpose of shortening the stitch in making the welt, and that
when the lever 120 is adjusted to come in contact with the end of the screw
pin 129, the standard 127 is thrown outward, carrying with it the arms 128
and 133 thereby drawing the arm 146 nearer to the needles and forcing them
into the stitch wheel for lengthening the stitch in making the regular work,
and that when it is desired to still further lengthen the stitch for making the
slack or loose course the lever 122 is forced against the pin 130, which is adjusted

page_text: inward further than said pin 129 driving the standard 127 out beyond the point
it was carried by the lower lever 120.
As shown in Figs. 1 and 8, there is also another bracket 152 attached to the
upper surface of the ring plate 4 which has lateral supporting slotted plates 153
and 154 that are provided with upper levers 155 and 156 and lower levers 157
and 158 that operate against adjusting screw pins 159 and 160, which are held
in a vertical standard 161. These operate through a swinging arm 162, having
an adjusting screw 163, and a sliding arm 164, with the other connecting parts
to perform the same functions at another feed on the needle cylinders, as the
levers 120, 121, 122 and 123 on the bracket 117 herein before described.
A bracket 165 is attached to the ring plate 4, next in line to the bracket 117,
as shown in Figs 1, 8, and as broken away in Fig. 22, which has projecting from
its side the usual upper and lower slotted plates 166 and 167 to which are
attached an upper pair of levers 168 and 169 and a lower pair of
levers 170 and 171 which are constructed with interlocking pins in the slotted
plates to operate one upon the other in substantially the same manner as those
herein before described and shown in Figs. 15 and 16.
At one side of the bracket on the ring plate there is secured a downwardly
extending bracket 172 having bearings in its upper and lower ends supporting
a vertical shaft 173. This shaft extends above the upper bearing and has ad-
justably secured thereto two crank arms, 174 and 175, one above the other, each
of which extends at right angles to the shaft 173 to a point in front of the levers,
each of which has an upwardly projecting pin near its end.
The crank arms 174 and 175 are adjusted inwardly to bring their vertical
pins 176 and 177 within a short space of the levers 168 and 170, which operates
upon them, to swing the arms outward. On the lower end of the shaft 173 there
is adjustably attached a foot piece 178 that is at right angles to the shaft, and
extends over the top of the bracket 179 of the well known spring presser attach-
ment below, and is held in front of the vertical bar 180 of the presser, and is
forced in towards the needle cylinders by the coil spring 181 on the presser rod
to hold the presser wheel 182 against the needles of the upper cylinder to press
off the stitch in making the regular work.
When it is desired to withdraw the presser wheel 182 from the needles, to leave
the beards of the needles open, as is necessary in making the welt and the royal
rib, the lever 168 and 170, is forced against the pins 176, or 177 driving the end
of the arms 174, or 175 outward, thereby turning the shaft 173 and swinging
the foot piece 178 outwardly, carrying with it the vertical bar 180 that is rigidly
attached to the journal 183 that holds the presser, thereby withdrawing the
presser wheel 182 from contact with the needles of the upper cylinder.
Between the brackets 165 and 172 there is also attached to the ring plate 4
a bracket 184 as seen in Fig. 22, which is extended to the front of the plate on
a line with the levers 168 and 170 and has a downwardly projecting arm 185.
To the lower end of this arm there is pivotally attached a crank arm composed of
a forwardly projecting arm 187, and a vertical arm 188, on the side of which
vertical arm there is a lug and stop screw 186 for limiting the movement of
the arm.
As the vertical arm reaches the upper surface of the bracket 184, it
is bent back, forming a lateral arm 189 which extends over the bracket, its rear
end being bent upwards to form a stop 190 in which there is an adjusting
screw 191, that is adapted to contact with a depending lug 192 near the end of
the lower lever 171 on the bracket 165 hereinbefore described.
The outer end of the arm 187 has loosely attached thereto a connecting rod 193
that is pivotally attached to an adjusting bar 194, one end of which is pivoted
to a bracket 195, extending in front of the bed plate 2, while the other end is
loosely inserted in a hole 196, in the end of a link 197. The other end of the
link is rigidly secured to the outer end of a pintle 198 that passes through a
slot 199, in a bracket 200, that is attached to the bed-plate, and which has a
cam 201 rigidly secured to its opposite side, which rests against the needles of

page_text: the lower cylinder. This stationary cam has a recess 202 on its inner side, as
shown in Figs. 23, 24, and 25, and in this recess there is a T shaped sliding
cam 203 which is attached to the inner side of the pintle 198 and is moved up
or down in the recess to regulate the length of the stitch on the lower needles
as may be necessary in changing from making regular work to making a welt,
or vice versa.
In making the regular work the cam 203 is pressed downward and held in
that position by the lug 192 on the lever 171 which forces screw pin 191 in the
end of arm 189 outwardly and the crank arm 186 is tilted downward, carrying
with it the connecting rod 193 and the bar 194 which, through the link 197,
depresses the cam to its lowest point where it is held.
When it is desired to change the stitch to that of making a welt, the lever 171
is moved off the end of the screw pin 191, when the cam 203 is at once forced up
into its seat by the strain of the yarn in drawing up the needles and is held in
that position by that means until the lever 171 again forces the cam down.
On the upper surface of the bed plate 2 near the bracket 200 there is attached
a bracket 204, as seen in Figs. 1, 13 and 14, having an upwardly inclined
socket 205, in which there is placed the well known presser rod 200. This rod
has a sleeve 207 inserted in the socket and is retained in a fixed position therein
by a set screw 208. The lower end of the rod has one end of a coil spring 209
secured thereto, while the other end of the spring is attached to the sleeve. The
upper end of the rod is provided with a presser finger 210 which is adjustably
secured thereon by a screw 211.
In operation the coil spring is so adjusted as to bring mild pressure on the
finger 210 which extends in between the needle cylinders in order to keep the
regular work forced back, and in making the welt, where several courses are knit
on the lower needles alone, to keep the work forced back between the cylinders
until the courses are finished when the needles of the upper cylinder are again
brought into operation and the knitted courses turned over upon themselves and
their edge joined to the regular work to complete the welt.
A bracket 212 is attached to the bed-plate 2 in front of each stitch wheel 149
for the purpose of supporting a standard 213 adjustably held therein which has
a guard finger rigidly attached to its upper end. This finger is in front and
near the needles, at their crossing point between the cylinders and is extended
to a foot piece 148 on the arm 146, and is for the purpose of keeping the needles
from being raised out of their slots in case of a bunching up, until they have
passed by the foot piece.
In Fig. 1 of the drawings I have omitted some of the cams used to push the
needles of the lower cylinder up, and I have also omitted the stationary pressers
which act on the barbs of the lower needles. It is to be understood however,
that these parts will be employed and they may be of any ordinary or well known
construction suitable to do the knitting in the usual manner on circular knitting
machines, and they are omitted for the purpose of preventing obscurity in the
drawings. It is also to be understood that the action of the needles of the lower
cylinder is the same in making regular work, a loose course, the royal rib, or
the welt. In the machine illustrated, four feeds will be employed, and may be
referred to as No. 1, No. 2, No. 3, and No. 4. Nos. 1 and 2 being illustrated, and
No. 1 being to the left of Fig. 1, and Nos. 3 and 4 following in the regular order
of succession after No. 2.
The special mechanism for changing the stitch at each feed is duplicated with
the following exception the lever 106 will be employed only between the feeds
No. 1 and 2; the levers 122 and 123 or 155 and 156, which are for the same
purpose, will be omitted at the feeds Nos. 3 and 4: levers 170 and 171 and the
mechanism operated by them will be present at feed No. 1 only and levers 168
and 169, and the mechanism operated thereby will be present at feeds No. 1 and 3.
It is not, however, to be understood that my invention is limited to machines
B

page_text: with four feeds, only, as the number of feeds may be increased or decreased as
desired. Should the feeds, be increased, the additional feeds should be provided
with the special mechanism similar to feeds Nos. 3 and 4.
In operation when the machine is engaged in making the regular work, the
levers are in position as shown in Fig. 8 with levers S7 and 104 forcing the
pins 92 and 108, respectively, outward carrying with them lever 95 and arm 109
which depress the cams 101 and 115 there by forcing the needles downward, and
with the levers 120 and 158 forced outwards carrying with them the standards 127
and 161, the arms 124 and 162 and 134 and 164 and their connections, thereby
drawing the foot piece forward against the needles, pressing them into the stitch
wheels for making the stitch of the usual length, and with lever 171 in position
to force the pin l outward which carries outward with it the angle arm 186
and through its connecting rod 193 depresses the adjustable cam 203.
During the operation of the machine the wheel 21 will be kept moving, step
by step, carrying the pattern chain with it, but while the machine is knitting
regular work the pattern wheel 31 will be at rest, the pawl 38 being held out of
engagement with the ratchet 39 by means of the pin 40 and lever 30, the latter
being elevated by a pin 42 in the pattern wheel.
To change the stitch from the regular work it will be necessary to start the
pattern wheel and to do this the pattern chain 23 will be arranged on the
wheel 21 to bring one of its cam links 24 into engagement with the lever 28 at
the proper time, which will lift the latter and thereby move the lever 30 off the
pin 42 and permit the pawl 38 to engage its ratchet, and the pattern wheel will
then be moved. It is also to be understood that when the pattern wheel is at
rest and the machine is doing regular work the levers 52, 62 and 69 will rest
at their free ends on the periphery of the wheel.
If it is desired to knit a loose course a pin 43 will be inserted in the pattern
wheel just behind the free end of the lever. 52 and when the pattern wheel is
moved the lever 52 will ride up on said pin, which will result in turning the
journal 51, and through the medium of the lever 53 and arm 55, will change the
inclination of the switch plate 5S to bring its free edge downward, so that when
the cylinders are revolved the upper shipping pin S1 will ride up on the inclined
surface of the switch plate and bring the lower pin 81 into operative position,
and it will remain in this position during one revolution of the cylinders.
As the stand 8 is carried around by the cylinder, the lower shipping pin 81
thus raised comes in contact successively with levers 122 and 155, forcing them
against the pins 130 and 159 in front, moving the standards 127 and 161 further
out than before, carrying with them the connecting arms and forcing the foot
pieces closer upon the needles crowding them still further into the stitch wheels,
thereby lengthening the stitch. Said shipping pin 81 also strikes the lever
arm 106 forcing it forward and thereby moving the lever 104 out of engagement
with the pin 108, releasing the angle arm 109, when the needles will carry the
cam 115 up and thus prevent the upper needles from being forced down at this
point while the slack course is knitted on the needles of the lower cylinder.
Just before the completion of the revolution above referred to, the roller 10
will pass over the cam and thereby operate the pawl 38 and move the pattern
wheel one notch which will move the pin 43 from below the lever 52 and permit
the free end of the latter to fall on the periphery of the pattern wheel and thereby
reverse the inclination of the switch plate 58. As the stand 8 is carried around,
the shipping pin 81 comes under the switch plate 58 and the series of pins 81
are thereby forced down in the slots to their original position, when the lower
pin 81 will come in contact with levers 123 and 156, carrying them forward and
moving levers 122 and 155 off the screw pins in front, thereby enabling the
standards 127 and 161 with all their connecting arms to drop back towards the
cylinders, carrying with them the foot pieces 148, releasing the pressure of 5
the needles and changing the stitch to that of the regular length.
In the same
"

page_text: revolution of the stand 8 the lower shipping pin S1 strikes the lever 104 carrying
it forward against the pin 108, thereby throwing the lever 107 outward and
tilting the angle arm 109 which forces the cam 115 down to its original position
for depressing the needles of the upper cylinder for making the regular work.
In placing the machine in position for making the royal rib, the lever 62 is
drawn up on the head of a screw pin 46, previously placed in the desired position
in the pattern wheel 31, thereby tilting the journal 61 in the bearings 50, raising
the lever 63 which rocks the shaft 66, throwing the switch plate 67 down against
the stop 59 for the purpose of raising the second series of shipping pins in the
stand 8.
As the cylinder revolves the upper pin 82, in the stand is forced up over the
incline surface of the switch plate 67 and the series is raised in the slots and
held in position by the spring 76. As the stand is carried around, the lower
pin 82 comes in contact with the lever 168 rocking it into engagement with the
pin 176 thereby throwing the arm 174 forwards, turning the shaft 173 and
moving the foot piece 178 outward which carries with it the journal 183 removing
the presser wheel 182 from contact with the needle beards on the upper cylinder
for the purpose of leaving them in a raised position at this point so the thread
will pass under the beard and be held on the needle while the courses of the
royal rib are being knit, while at a point further around on the upper cylinders
a like presser wheel is performing its regular work in pressing down the beards
of the needles for the purpose of allowing the stitches to pass over the beards
and be cast off the needles.
To set the mechanism for knitting the royal rib, the pattern wheel is started
by the pattern chain in the manner already described, namely, by a cam link 24
engaging the lever 28 and thereby permitting the pawl 38 to drop into its ratchet.
When the pattern wheel is moved one notch the lever 62 will ride up on a pin 46
and the same movement of the pattern wheel will move a pin 42 under the
lever 30 which will again lift the pawl 38 out of engagement with the ratchet
and the pattern wheel will remain at rest with the lever 62 elevated until the
desired number of royal rib courses have been knitted. The number of course's
will be governed by the pattern chain which will have a second cam link 24
at the proper distance behind the link 24 which started the pattern wheel, and
as soon as this second link engages the lever 28 the pattern wheel will be again
started and move the pin 46 from below the lever 62, dropping the end of the lever
down on the wheel, rocking the connecting levers and arms and thereby tilting
the switch plate 67 up into its original position. As the shipping pin 82 passes
around under the plate, it is forced down to its lowest position in the slot 80,
when in its course it comes in contact with the lever 169, carrying its end for-
ward and throwing lever 168 off the pin 176, thereby enabling the arm 174 to
swing back, turning the shaft 173 and foot piece 178, when the spring 181 forces
the presser wheel back on the needles placing the machine again in condition
for performing the regular work.
The same movement of the pattern wheel which releases the pin 46 from the
lever 62 may also, if desired, move another pin 42 under the lever 30 and stop the
movement of the pattern wheel as before described.
To change the stitch for making the welt, the pattern wheel 31 will be moved
to bring the pin 48 into engagement with a lever 69, and there will be as many
pins 48 arranged in succession as may be necessary to keep the lever elevated
while the necessary number of courses in the welt are knitted.
Raising the end of the lever 69 rocks the shaft 68 and raises the lever 70 and
through the link 71, tilts the arm 72 upwards carrying the switch plate 74
downwards on the lug 59 where it remains as long as the courses are being made
for the welt. As the stand 8, is moved around, the third series of shipping pins
are raised to the top of the slots 80 by the upper pin 83 being forced up and
over the inclined switch plate 74.

page_text: .
As the stand moves forward the lower pin 83 comes in contact with the
levers 85 and 105 carrying their ends forward and there by moving the levers 87
and 104 off the pins 92 and 108 enabling the arms 93 and 107 to move in towards
the cylinders, when the needles will force the cams 101 and 115 up and out of
action and the knitting is done on the lower needles.
The pin 83 also comes in contact with levers 121 and 157 moving
their ends forward and thereby turning the levers 120 and 158 off
the screw pins in front, permitting the standards 127 and 161 to
move in towards the cylinders thereby releasing the connecting levers
and arms, enabling the coil springs 140 to draw the sliding arms 132
back, carrying with it the downward extending arms 146 and the foot pieces 148,
to prevent forcing the needles into the stitch wheel and thereby shortening the
stitch. The same pin 83 strikes the end of lever 170 and moves it into engage-
ment with pin 177, turning the arm 175 outward, rotating the vertical shaft 173,
carrying the foot piece 178, and with it the journal 183 thereby removing the
presser wheel 182 from the beards of the upper cylinder needles. As the pin 83
turns the lever 170 the lever 171 is moved so that its lug 192 is released from
the screw pin 191 when the knitted work draws up the connected arm 203, pres-
sing upwards the link 197 and the arm and connecting rod 193, tilting back the
crank arm 186 for releasing the strain on the yarn when passing the cam.
When the number of courses have been made for the desired width of the
welt by this process, the machine is then changed to perform the regular work
and the courses of the welt are folded over upon themselves and the two edges
of the welt are united by bringing into action the upper cylinder needles.
In returning the machine back to the regular work, the lever 69 drops off the
head of the screw pins on the pattern wheel 31, thereby tilting the shaft 68,
lever 70, arm 72 and the connecting shaft 73 and raising the switch plate 74
to its original position.
As the stand 8 is moved around, the pin 83 passes under the switch plate and
is forced down into its normal position and when it is turned around on the
cylinder it comes in contact with the levers 87 and 104 carrying their ends for-
ward in contact with the pins 92 and 108 forcing the arms 93 and 107 outward
against the angle arms 95 and 109 tilting them outward and forcing the cams 101
and 115 downward, thereby depressing the needles for the regular work. The
same pin 83 in its revolution, comes in contact with levers 120 and 158 and
again brings their front ends in contact with the pins in front, forcing the
standards 127 and 161 outward which carry with them the connecting arms,
again bringing the foot pieces on the downwardly extending arms, further for-
ward pressing the needle deeper into the stitch wheels and thereby lengthening
the stitch as is necessary in the regular work.
This pin 83 also strikes the levers 171 removing the lever 170 from contact
with the pin 177, when the crank arm 175 is forced inwards by the action of
the coil spring 181 through its connecting arms and shaft, and the presser
wheel 182 is again brought into contact with the needles of the upper cylinder
when it is in position for doing its regular work. As the shipping pin 83 strikes
the lever 171 the lug on its front end is brought into contact with the pin 191
forcing the arm 189 outwards, carrying with it the crank arm 186 thereby de
pressing the rod 193 and the bar connected therewith and the link 197 forcing
the sliding cam 203 downward into its normal position for making the regular
work.
As a modification of my invention the upper pins 81, 82 and 83 which are
engaged by the switch plates to throw the lower pins into or out of operative
position may be omitted, and the switch plates be so arranged as to be in the
path of the lower pins 81, 82 and 83 and act on them directly. It is also to be
understood that other changes in the form, proportions and minor details of
construction, may be resorted to without departing from the scope or sacrificing
any of the advantages of my invention.
