PROVISIONAL SPECIFICATION.
Improvements in Circular Rib Knitting Machines and Fabrics
Produced thereon.
I, CHARLES GILBERT of 86 Crafton Street, Leicester, Hairy Machine
Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in circular rib knitting machines and
fabrics produced thereon, and has special reference to means or apparatus whereby
the rib needles of such machines may be actuated at desired intervals and to a
suitable extent to perform the operation commonly known as "shogging," ie. con-
veying to the rib needles a slightly lateral movement during the revolution of the
machine, to automatically produce a combination of fancy courses of fabric,
especially applicable to the cuffs of Cardigan jackets, sweaters, mitts or other
articles where any fancy courses or patterns are desired to add a finish to the
article.
The ordinary style of circular rib machine may be employed, ie, circular rib
machines having swing jacks, the cams being stationary and operated in the usual
manner.
In the operation of "shogging," the rib needles, which intercalate with the
maine needles require to in moved a short distance literally.
To effect this result the following mechanism may be employed;-
The usual pattern wheel carries on its upward face, (in addition to the usual
projections or studs which actuate the shaped lover employed to act upon the
jacks), a number of supplementary studs or equivalent projections. The pattern
wheel is mounted on a spindle carried in the bed of the machine and caused to
revolve in the usual well-known manner.
At a point adjacent to the cylinder and the pattern wheel and alongside
the shaped lever before mentioned, may be pivotted a horizontal lever, projecting
over the face of the pattern wheel in a line above the supplementary studs
previously mentioned in such a manner that at desired intervals, these studs will
come under the said horizontal lever or a projection on its side and slightly raise
its inner end to which is connected a vertical rod passing upward through -uitable
guideways to the top of the machine.
The main spindle which carries the jacks and other mechanism above the ribbing
dial (the cylinder being independently retated in the usual manner) has near its
upper end an arm which may be attached to or formed integrally therewith, the
said arm bearing on its outward end a "star" wheel or equivalent the periphery of
which is formed with a series of projections and recesses.
The stud or spindle mounted in the arm and which carries the "star" wheel
just mentioned, also carries a ratchet wheel and lever, the latter projecting
sufficiently outward to come into the path of the vertical rod at such times as it is
elevated through the horizontal lever by means of the supplementary studs.
The ratchet wheel lever is spring controlled and carries a pawl which actuates
the ratchet wheel.
The spindle arm may come immediately above the face of the usual spur wheel
mounted on the main spindle and there may be attached to the upward face of the
aid wheel two or more lugs or projections in which may be carried adjustable
tuds to engage with the projections and recesses on the periphery of the "star"
wheel.

end to engage in holes or recesses on the face of the "star
wheel.

When making a sleeve or other article, after knitting a number of courses, of
for instance "polka rib," and the point is reached where the fancy courses are
desired, I may through the medium of the supplementary studs on the pattern
wheel and the other mechanism constituting this invention, knit a number of courses
of twill shog," 1 and 1 rib, and "royal," or such other combinations as desired,
the pattern being limited only to the number courses made during one complete
revolution of the pattern wheel, the supplementary studs of which net on the
horizontal lever and other mechanism described, whereby the shogging of the rib
needles is eflected and the desired fancy courses in the fabric the result.

Improvements in Circular Rib Knitting Machines and Fabrios
Produced thereon.
I, CHARIPS GILREET of 86 Crafton Street, Liceter, Hiery Machine
Builder, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement:—
This invention relates to improvements in circular rib knitting machines and
fabrics produced thereon, and has special reference to means or apparatus whereby
the rib needles of such machines may be actuated at desired intervals and to a
suitable extent to perform the operation commonly known as "shogging," ie, en
veying to the rib needles a slightly lateral movement during the revolution of the
machine, to automatically produce a combination of fancy courses of fabric,
especially applicable to the cuils of Cardigan jackets, sweaters, mitts or other
articles where any fancy courses or patterns are desired to ad 1 a finish to the
article.
The ordinary style of circular rib machine may be employed, the machine
hereinafter described and having my improvements applied having awing jacks, the
cams being stationary and operated in the usual manner.
In the operation of shogging, the rib needles, which intercalate with the machine
needles require to be moved a short distance laterally.
To effect this result the following mechanism may be employed;-
The usual pattern whed carries on its upward face, (in addition to the usual
projections or studs which actuate the L shaped lever employed to act upon the
jacks through the medium of the usual machine cam) a number of supplementary
studs or equivalent projections.
The pattern wheel is mounted on a stud or spindle carried in the bed of the
machine and caused to revolve by means of a pawl connected to a lever or lever-
and operated by a cam on the machine in the usual manner.
At a point adjacent to the needle cylinder and the pattern wheel and alongside
the shaped lever before mentioned, may be pivoted a horizontal lever, projecting
over the face of the pattern wheel in a line above the supplementary studs
previously mentioned in such a manner that at desired intervals these studs will
come under the said horizontal lever or a projection ou its side and slightly raise
its inner end to which is connected a vertical rod passing upward through suitable
guideways to the top of the machine.
The main spindle which carries the jacks and other mechanism above the ribbing
dial or cup (the cylinder being independently rotated) has near its upper end an

page_text: arm which may be attached to or formel integrally therewith, the said arm bearing
on its outward end a "star" wheel or equivalent, the periphery of which is formed
with a series of projections and recesses.
The stud or spindle mounted in the arm and which carries the star wheel just
mentioned, also carries a ratchet wheel and lever, the latter projecting sufficiently
outward to come into the path of the vertical rod at such times as it is elevated
through the horizontal lever by means of the supplementary studs. The ratchet
wheel lever just mentioned is spring controlled and carries a pawl which actuates
the ratchet wheel.
The main spindle arm may come immediately above the face of the usual spur
wheel mounted on the said spindle and there may be attached to the upward face
of the said wheel two or more lugs or projections in which may be carried
adjustable studs to engage with the projections and recesses on the periphery of
the star wheel.
The top end of the main spindle may also carry a spring, studded at its end to
engage in holes or recesses on the face of the star wheel.
"
When making a sleeve or other article, after knitting a number of courses, of
for instance "polka rib and the point is reached where the fancy courses are
desired, I may through the medium of the supplementary studs on the pattern
wheel and the other mechanism constituting this invention, knit a number of courses
of twill shog," "1 and 1 rib," "royal" and "royal shogi or such other
combinations of same as desired, the pattern being limited only to the number of
courses made during one complete revolution of the pattern wheel, the supplementary
studs of which act on the horizontal lever and other mechanism described, whereby
the shogging of the rib needles is effected and the desired fancy courses in the
fabric the result.
The invention will be more completely understood by reference to the drawings
accompanying this specification, in which so much only of a circular rib knitting
machine is shown with my improvements attached as to clearly exhibit the
invention.
Figure 1 is a front elevation partly in section of part of a circular rib knitting
machine, having my improvements applied thereto.
Figure 2 is a side elevation of the racking mechanism and Figure 3 a plan of
same with some additional parts of the machine also shown.
Figure 4 is a sectional plan showing the star wheel.
Figure 5 is a plan showing the pattern wheel with the horizontal lever.
Figures 6 and 7 are details hereinafter referred to.
Referring to the drawings A is the usual spindle receiving its motion in the
well-known manner by a bevel wheel on the driving shaft (not shown in the
drawings). The said spindle A is carried in bearings A' A 2 (the latter attached
to a cross Lar F 5) and has keyed on its top end a spur wheel A 3 which gears
into the spur wheel B carried loosely on the main spindle B' the latter also carrying
the revoluble parts down to and including the dial or cup C (Fig. 1). D is the
usual machine cam for pressing inward the jacks D', being actuated by the
Lshaped lever D2 and pattern wheel D 3 with its studs or projections D4 in
the well-known manner.
As before stated my invention consists of apparatus by means of which the
jacks D' carrying the rib needles D* may be shogged at such times as they are in
their inward position, such shogging producing a combination of fancy courses in
the fabric as before mentioned.
To effect the shogging described the pattern wheel I 3 carries upon its face, a
number of supplementary studs or equivalent E secured to the face of the said
wheel D 3 by countersunk screws E.
The studs E are arranged to shog the rib needles to produce a combination of
fancy courses in the fabric as before stated the pattern produced depending mainly
upon the arrangement of the supplementary studs E as is well understood by those
used to this class of machine, the studs E shown in Figure 5 making seven shog

page_text: courses and five plain courses (or 24 courses of 1 and 1 and 12 courses of royal)
during one revolution of the pattern wheel.
The horizontal lever F is pivoted at F1 to a bracket or plate F2 fixed by
bolts F3 to the bed 4 of the machine, the said lever having on its site a
projection F to engage the supplementary studs on the pattern wheel D 3.
The front end of the lever carries a stud or pin G' which passes into the
lower end of a vertical rod the latter being carried in a guideway or bracket G2
Gxed by bolts G 3 to a cross har F5 of the machine.
It will be readily understood therefore, that as the pattern wheel D3 is racked
round in the well known manner in the direction of the arrow, Figure 5, the
studs will come under the projection F on the lever F and slightly raise the
latter and with it the vertical rod G, the latter with other mechanism affor ling
the means for imparting the shogging motion to the rib needles as before stat al.
On the top of the main spille B is attached the arm I carrying a stul H³
upon which are mounted the star wheel H 2 and ratchet wheel H3 the two latter
working together loosely upon the stud H. Upon the upper end of the stud I
is loosely mounted the lever carrying the pawl J1 (kept to its work by the
spaing 2) on one end and the finger 3 on the other end adapted to come into
contact with and be actuated by the vertical rod G (as shown in its dotted line
position see Figure 3) as before described,
In its dotted line position Figure 3, the lever J is almost sufficiently rachel to
allow the inner edge of the finger 3 to pass along the outer edge of the
vertical rd G by which time the racking operation will Le quite completed.
Formed integrally with or fixed to the pur wheel B are lugs or brackets KK
carrying in their ends the adjustable gange studs 1. L' (not shown in Figure 3)
held in position by the lock nuts thereon. The said gauge stals 1. L' engage
with the projections atal recesses in the star wheel 12 and by these means
neting in conjunction with the vertical rod G and lever J the arm II and with it
the main spindle B' and dial or cup C are moved either to the right or left
alternately at each rack of the star wheel H 2. The gauge stal L is in a recess
(shown in Figure 4) so at the next shogging operation the shog will be to the right,
the star wheel 12 racking in a contrary direction to the travel of the spur
wheel B.
Attached to the arm H is a string M having a stud M' adapted to engage in the
recesses M2 in the star wheel H 2 and by which means the latter is steadied at
each racking operation.
The plate Nis fixed to the boss A* of the spur wheel A 3 and is about a third
of a circle in length and adapted for holding up the vertical rol G by means of the
plate attached to the latter during and after the shogging operation and until
the racking of the star wheel has been fully performed, the bottom of the plate (
riding upon the upper face of the plate N.
The cam (which with the usual levers and pawl not shown) racks the pattern
wheel 13 in the well-known manner, is arrange to give a slight dwell during the
shogging of the rib needles D* and a further slight rack after the shogging
operation is performed to deliver the shaped lever D 2 off the studs (not shown)
which operate same.
A projection Q is formed on one of the lugs or brackets K to carry the
adjustable pin or bolt Q' to hold the lever in its position to engage the
vertical rod G at such times as the latter is elevated as before described.
It will he rendily understood that the studs or equivalent D4 (Figs. 5 and 7)
are so shaped as to give the machine cam D a varying inward movement and the
fancy courses are obtained through the shogging of the rib needles D* as beforo
described, during such movement.
By removing any part of the circle of rib needles D* the fancy courses may
be knitted at any part of the circle of fabric only.
A pattern chain could be readily arranged as a substitute for the pattern
wheel.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. A circular machine knitted ribbed fabric one or more portions of which are
formed of a combination of all or any two of the said fancy courses, substantially
as described.
