PROVISIONAL SPECIFICATION.
Improved Apparatus applicable to Straight Bar Knitting Machines.
1, HERBERT KIDDIER, of the firm of John Kiddier and Son, of Globe Works,
Waterway Street, Nottingham, Hosiery Machinists, do hereby declare the nature
of this invention to be as follows:-
I apply my improved apparatus to machines described in the Specification of a
Patent granted to John Kiddier and Herbert Kiddier for Improvements in
Knitting Machines No. 41 January 4th 1881. The improved apparatus consists of
an extra rocking shaft placed at the back of a straight bar knitting machine pro-
ducing broad ribbed fabrics.
The shaft is provided with a lever to each division, or each two divisions of the
machine. The front end of each lever has the lower end of a link hinged to it, the
upper end of each link carries an axle or axles, each capable of being made to
engage, or disengage with the back end of one of a pair of arms which carry a
right angled presser or series of pressers.
.
The front ends of the arms are hinged to levers carried by and rocking with a
shaft carried by bearings secured to the framing of the machine.
Both shafts are provided with truck bearing levers operated by cams on the usual
cam shaft, by which means each right angled presser has falling and rising move-
ments, and to and fro horizontal movements communicated to it. And instead of
the knocking over cam c¹¹ Figure 7 shown on Sheet 4 of the Specification above
referred to, I employ a knocking over cam of such shape that the whole of the
movements are effected by it without shortening that portion of the cam employed
while the drawing of the threads to form the loops is being made. To prevent the
loops on the machine needles being cut when the frame needles first deliver their
loops onto the machine needles, I either lower the top edge of certain of the
knocking over bits or raise the heads of certain of the frame needles.
When the above described apparatus operates in conjunction with a machine
producing broad ribbed fabrics, the movements are as follows:
When the loops are drawn on the frame needles by the jack sinkers, the catch
bar operates the dividing sinkers to divide the loops on the frame needles their
beards being pressed in the usual way, the frame needles are then lowered to deliver.
some of the loops to the machine needles their beards being pressed in the
usual way, the frame needles rise and the right angled pressers press the beards of
those frame needles which are between the machine needles as the frame needles
fall to knock over the loops formed on them, thus completing the movements
required to form each course of work when making broad ribbed fabrics.
By the above described means the number of courses made per minute, and the
quantity of fabric produced is considerably increased.

I, HERBERT KIDDIER, of the firm of John Kiddier and Son, of Globe Works,
Waterway Street, Nottingham, Hosiery Machinists, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a vertical sectional view of my improved apparatus looking from
the left end of the machine to which it is applied.
Figure 2 shows a front view of the improved apparatus.
Figure 3 is a vertical sectional view showing the position of a right angled
presser A when pressing the frame needles.
I apply my improved apparatus to machines described in the Specification of a
Patent granted to John Kiddier and Herbert Kiddier for Improvements in Knitting
Machinery No. 41 January 4th 1881.
At Figure 1 of the drawings of the said Specification and at Figure 1 of the drawings
accompanying this Specification the corresponding parts are indicated by like letters
as follows, is the cam shaft, e the frame needles, the frame needle bar presser
shaft, d the machine needles, do the machine needle bar shaft, e the sinker bar, the
sinkers, the machine slide, and the machine slide shaft. My improved apparatus
consists of an extra rocking shaft A "see Figure 1" placed at the back of a straigh
bar knitting machine producing broad ribbed fabrics.

The shaft is provided with a lever A' to each two divisions of the machine. The
front end of each lever has the lower end of a link A2 hinged to it, the upper end
of each link carries two axles B, B, each engaging with the back end of one of a
pair of arms B¹ which carry a right angled presser A³.
These pressers are interchangeable according to the ribbed fabric to be produced.
The presser shewn at Figure 3 being cut to press one frame needle and misspress
three needles alternately for making a three and two ribbed fabric, when making a
six and three rib, the pressers would be cut to press two frame needles and misspress
six needles.
The front ends of the arms B₁ are hinged to levers B2 carried by and rocking
with an additional shaft B³ supported by bearings secured to the framing of the
machine.
The shaft B³ is provided with one or more truck bearing levers B* each operated
by a cam B on the usual cam shaft beach truck being held to its cam by a spring
in the usual way. The shaft A is provided with one or more truck bearing levers A
each operated by a cam A' on the cam shaft b, by which means each right angled
presser has falling and rising movements, and to and fro horizontal movements
communicated to it.
Instead of the knocking over cam c" Figure 7 shown on Sheet 4 of the Specifica-
tion above referred to, I employ a knocking over cam C as shown at Figure 3 of such
shape that the whole of the movements are effected by it without shortening that
portion of the cam employed while the drawing of the threads to form the loops is
being made.
When the above described apparatus operates in conjunction with a machine
producing broad ribbed fabrics, the movements are as follows:-
When the loops are drawn on the frame needles by the jack sinkers, the catch
bar operates the dividing sinkers to divide the loops on the frame needles their
beards being pressed in the usual way, the frame needles are then lowered to deliver
some of the loops to the machine needles their beards being pressed in the usual
way, the frame needles rise and the right angled pressers press the beards of those
frame needles which are between the machine needles as the frame needles fall to

page_text: knock over the loops formed on them, thus completing the movements required to
form each course of work when making broad ribbed fabrics.
By the above described means the number of courses made per minute and the
quantity of fabric produced is considerably increased.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
The construction and employment of improved apparatus operating in conjunction
with straight bar knitting machines substantially as described for the purpose
specified and illustrated in the drawings annexed.
