PROVISIONAL SPECIFICATION.
Improved Apparatus applicable to Straight Bar Knitting Machines.
We WILLIAM SAMUEL WARD, Factory Manager, and HERBERT FRANCIS
LANCASHIRE, Manager, both in the employment of J. B. Lewis and Sons,
Limited, Stanford Street, Nottingham, Hoisery Manufacturers, do hereby declare
the nature of this invention to be as follows:-
The boxes of the narrowing machines of straight bar knitting machines are made
wider than usual and slotted vertically, each slot being provided with a jack
carrying a transferring point at its lower eud.
The upper end of each jack projects backward over the front end of one of a
series of plates which radiate from a shaft, rocking in bearings secured to the
narrowing machine brackets. The rocking of the shaft is effected by cams and
truck bearing levers. Above the jacks is a bar provided with cranked springs
which receive the jacks, carrying the points not required to work when lifted by
the rocking of the shaft before named.
By the above described apparatus we are enabled to make perforations in the
fabric automatically with perfect lines and selvages through the narrowings.

statement:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a front view of our improved apparatus as applied to each divis
ot a straight bar knitting machine, portions of certain shafts and bars between the
harrowing boxes being broken away.
Figure 2 is a left end view of the apparatus showing the shafts and bars in
section.
-
Figure 3 is a reduced drawing showing the left side of a link, truck bearing lever
and cam for operating a rocking shaft referred to hereafter.
.
The corresponding parts in each figure are indicated by the same numbers where
necessary.
The boxes 1 of the narrowing machines of straight bar knitting machines are
made wider than usual, the boxes to the right being carried by a sliding bar 2
and the boxes to the left by a bar 3, both bars being supported by three bearing
10 brackets 4 to each division of the machine and operated in the usual way, the right
end bracket only is shown in the drawings. The additional width of each box
is slotted vertically, each slot being provided with a jack carrying a trans-
ferring point 6 at its lower end, these points are in addition to the five transferring

The boxes 1 of the narrowing machines of straight bar knitting machines are
made wider than usual, the boxes to the right being carried by a sliding bar 2
and the boxes to the left by a bar 3, both bars being supported by three bearing
brackets 4 to each division of the machine and operated in the usual way, the right
end bracket only is shown in the drawings. The additional width of each box
is slotted vertically, each slot being provided with a jack 5 carrying a trans-
ferring point 6 at its lower end, these points are in addition to the five transferring

page_text: points at each selvage. The upper end of each jack projects backward to lie
successively over the front end of one of a series of plates 7 which radiate
from a shaft 8 rocking in bearings 9 secured to the underside of the usual
narrowing machine brackets. The shaft 8 is provided at either or both ends with
an arm 10 connected by a link 11 to a truck bearing lever 12 operated by a
cam 13 on the usual cam shaft, the lever 12 rocking on an axle secured in an
arm attached to one of the back rails of the knitting machine framing. Above the
jacks 5 in each narrowing box is a bar 14 each held by two arms 15 secured at
their lower end to the sliding bar carrying the box, the outer arms only are shown
in the drawings. Each bar 14 has leads of cranked springs 16 secured to it which
receive the jacks 5 carrying the points 6 when lifted by the plates 7, radiating from
the shaft 8 holding the jacks up not required to work as shown by dotted lines at
Figure 2.
The movements of the apparatus when operating in conjunction with a straight
bar knitting machine are as follows:-
Each time the narrowing machine operates, the five narrowing points at each
selvage move inwards two needles in the usual way, and each vertical sliding point
when at work at the same time transfers the stitch from one needle to the next
needle but one inwards.
By employing narrowing point boxes fitted with jacks to carry extra points to
make perforations, instead of the points being fixed as heretofore, we are enabled
when required by automatically lifting one of the points to cease making any given
hole, or to make perforations in the fabric with perfect lines and selvages through
the narrowings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
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.
