Year: 1889

page_text: on the left side of the right covering box A carried by the usual lower narrowing bar,
see Figures 2 and 4, we provide a boss A' hinged covering box A2, slides numbered 1. 2. 3
and 4 each carrying a filling up point, and a like number of parts as above described,
but arranged from right to left.
For producing vertical widenings between the gores we employ two additional
covering boxes A1, one upon each side of the centre of each division, see
Figures 1 and 2, each box carries the requisite number of covering points and is
provided with two slides numbered 5, and 6, carrying filling up points A³, held clear
of the covering points when not in use by springs A₁ the same as the slides 1.2.3
previously described.
The box A on the left of the centre of each division slides on the usual upper
narrowing bar, to the right of the left covering box the upper narrowing bar
is clipped by a friction box F, carrying a short bar F, through which, and through
the front of the friction box a set screw is passed, provided with a lock nut F2, the set
screw pressing upon a plate f, shown at Figure 3 and a strip of leather placed between
the plate and the narrowing bar, provides means for adjusting the friction, the bar F
at its right end carries a slotted top piece F3 adjusted by two screws to regulate the
distance between the two covering boxes A10.
The box A10 on the right of the centre of each division slides on the usual lower
narrowing bar, which is clipped to the left of the right covering box by a
friction hox F, carrying a bar F1 set screw and lock nut F2 and slotted top piece F³
as before described.
The inward traverse of the boxes A10 are effected by the following means, the boxes
to the left of the centre of each division are secured at the back to a bar G, see
Figures 5 and 6, the left end of the bar, is slotted and capable of adjustment on a
short bar G¹, sliding in a bearing G² secured to the back of the narrowing bar
bracket at the left end of the machine, the right end of the bar G being stopped by
the inner edge of a bearing G³ at the back of the narrowing bar bracket at the right
end of the machine.
The boxes A10, to the right of the centre of each division are secured at the back to
a bar G slotted at its right end capable of adjustment on a bar G¹, sliding in a
bearing G³, secured to the back of the narrowing bar bracket at the right end of the
machine, the left end of the bar & being stopped by the inner edge of a bearing G2,
at the back of the narrowing bar bracket at the left end of the machine.
The bars Gare traversed inwards the requisite number of needles each time the
narrowing machine rises by the inclined ends of the bars G¹ each striking a bracket
secured to the fixed slur cock bar or to other convenient part of the framing of the
machine, the brackets against which the bars G¹ strike are not shown in the
drawings.
The bars G which are of sufficient length to pass over the back of each division of
the machine together with the narrowing bars and the narrowing machine shaft are all
shown broken through at Figures 5 and 6.
Each of the bars G at about the centre of the length of the machine is provided
with a stop piece G projecting from the back "see Figure 6" between which the
lower end of a vertical bolt H is lowered "as shown by the dotted line" when vertical
widenings are not being made, the bolt H slides in a bracket H secured to the
narrowing machine shaft, the bolt being held clear of the bars G by a stud H2 carried
by a plate spring secured to the side of the bracket engaging with the bolt as shown at
Figures 1 and 6.
The slides 5 and 6 in each of the covering boxes A10 are connected at their upper
end by a grooved bracket in which a bolt H³ slides, these bolts when in the position
shown by dotted lines at Figures 3 and 4 lie under an upper rod C₁ "hereafter
referred to " the rod depresses the slides when vertical widenings are
being made, the
bolts H³ are drawn towards the front of the machine when vertical widenings are
not required.
When the narrowed portions of gores are being made the slides 2.5 and 6 are.
depressed by the lower rods C' hereafter referred to.

page_text: The slides carrying the filling up points are moved into their proper position for
operating by the following means.
see
In front of the narrowing machine we mount three shafts 7. S. and 9 rocking in
bearings B which project from the front of the narrowing bar brackets, the shafts 7
and 8 have each as many pair of arms C secured upon them as there are divisions in
the machine, the shaft 9 is provided with two pair of arms C to each division, ".
Figures 1. 2. 3 and 4," the back ends of each pair of arms carry a rod C₁, the rods
carried by the arms on the shaft 7 depress the slides 1, 3, 5, and 6 on the left of the
centre of each division, the rods carried by the arins on the shaft S depress the
slides 1, 3, 5 and 6, on the right of the centre of each division, and the rods carried
by the arms on the shaft 9 depress the slides 2, 5, and 6, on both sides of the
division.
The rocking of the shafts 7. 8 and 9 are effected as follows.
The shaft is provided with an arm B' hinged to a link B2 shown at Figures
and 4.
The shaft 8 is also provided with an arm B¹ and link B³, shown only by dotted lines
at Figure 4.
The links B' are operated to rock the shafts 7, and 8, by apparatus the same as
shown and described in the Specification of a Patent granted to Edward Attenborough
and John Ward Kent No. 10,045 July 18th 1887 for improvements in Filling up
apparatus as applied to knitting machines known as Cotton's Patent.
By the side of the arm B¹ the shafts 7 and 8 are each provided with a three armed
lever I the one on the upper shaft is only shown in the Drawings which may be
rocked on the shaft by the attendant by means of the handle at the front end, "see
Figures 1 and 3" the back end of the lever has the lower end of a coiled spring
secured to it, the upper end of the spring being hooked on to the end of a lever
projecting from the back of the lever B' the vertical arm of the lever has a stud I³,
projecting from it which is held by the spring close to the back of the arm B¹.
Upon the attendant, pulling the handles of the levers down the shafts 7 and 8 will
be rocked to raise the upper rod C₁ and throw up the slides 4 to disengage the
catches A from the studs A7 then by raising the handles of the levers the rod t will
depress the slides 1 and 3 and set free the covering boxes A³ to be lifted by the
springs A when not required.
The shaft 9 is provided with an arm J hinged to a link J' see Figures 2 and 4
forming two hooks at the back end, when in use the lower hook engages with a stud
projecting from the upper end of an arm E secured on a shaft E described in the
Specification No. 10,045 in the year 1887, before referred to, when the slides 2, 5
and 6 are not in use the link J¹ is lifted by the attendant clear of the stud in the
arm E and the top hook is hooked on to a stud B' which projects from a bracket
secured to one of the narrowing machine arms.
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 the Improved apparatus operating in con-
junction with the filling up apparatus described in the Specification No. 10,045 in
the year 1887 before referred to. To produce gores of any shape, length, and
width, and vertical widenings at any portion of the whole width of fabric made on
each division of a straight bar knitting machine.
