WC, JOHN POTTERTON of No. 33 Arnold Street, Manager, JOHN PARTRIDGE,
ARTHUR DURRAD PARTRIDGE and JOSEPH ALLEN of No 1 Belvoir Street and
Post Office Yard, Glove Manufacturers trading as John Partridge and Son, all in
Leicester, in the County of Leicester do hereby declare the nature of this
invention to be as follows
This invention refers to improvements in or relating to rotary knitting machines,
to provide means or appliances for automatically producing tucked and fleecy
fabrics (which at the present time are only made on hand frames) upon power
driven glove fingering or handing machines.
To carry out this invention we proceed to arrange on the front rail of the
machine in suitable brackets, a sliding shaft of a suitable length and dimensions
adapted to raise and lower the falling bar to the several heights required.
Brackets are also arranged on the top of said sliding shaft which communicate
with the falling bai spindle and "star boxes" for the purpose of making slack or
easy courses in either the tuck or plain course in knitting tuck fabric. Upon the
end or other part of the before mentioned sliding shaft is arranged a time wheel
to work said shaft in its traverse the distance desired to make the necessary loop
(a short loop to take the slack thread away from the tuck stitch) and also to bring
the sinkers in their higher or lower position, as the case may be. Attached to
the face of the said time wheel are suitably shaped cams or tracks to which are
held, by suitable means a roller and truck on end of lever working in brackets on
the back rail or other position upon the rafters of the frame, said cams are of any
desired length
in order to regulate the distance of the traverse of the sliding
shaft in each alter uate course of knitting, and throughout the knitting operation,
being regulated by the size and number of teeth of the time wheel.
To produce a fleecy inside face on a tucked ground or surface, a sliding
traverse bar is arranged in suitable brackets on the back rail, or other convenient
part of the fiamo, and is also moved from "right to left" or vice versa by the aid
of suitable movable rollers and truck in connection with the top brackets, and
which will move upon the "small" presser, and "large" sinking cams, power and
locking cams of the desired shape all arranged together on said shaft, the said
tiaverse bar is either governed by the "time wheel" before mentioned having two
faces, or by another "time wheel" on end or other part of the frame, and brought
into action by similar means as herein before described with reference to the
making of the "tuck work."
Said "time wheel" controls the traverse bar and catches fitted on the truck
levers engage forked brackets on top of said bar and shifts the rollers from one
cam to another, and thus different motions are given to the frame to make the
length of loop necessary for the fleece
In fleecing the fabric, a slack course is made in place of an easy one by allowing
be front shaft of the machine to be shogged further than when "tuck work" 18
being made, this is done from the first "tine wheel' " in every 4 or 8 courses, or
nore or less as may be from time to time desired.

We, JOHN POTTERTON late of No. 33 Arnold Street, now of No 15 Chatham
Street, Manager, JOHN PARTRIDGE, ARTHUR DURRAD PARTRIDGE and JOSEPH
ALLEN of No 1 Belvoir Street and Post Office Yaid, Glove Manufacturers
trading as John Partridge and Son, all in Leicester, in the County of Leicester
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascontained in and by the following
statement
--
This invention refers to improvements in or relating to rotary knitting machines,
to provide means or appliances for automatically producing tucked and fleecy
fabrics (which at the present tune ate only made on hand frames) upon power
driven glove fingering or handing machines
In order that this our invention may be well understood a sheet of diawings
accompany this Specification, in which.
Figure 1 is a view looking from the top of a rotary frame, of the contrivances
forming the subject of this invention
Figure 2 is an end view showing the time wheel and means for moving the back
shaft, and pinion for turning said wheel
Figure 3 is a cut off view of the falling bar, star spindles, and stepped adjustable
points seemed on the falling bar shaft
Figures 4 and 5 are cains attached to the sinking and locking cams, and shew
the differences in shape of each for the several purposes hereafter specified, and
Figure 6 illustrates the positions of the lead sinkers, when the jack sinkers are
ready for locking up under the needles after the loop has been called to the head
ol onter extremity of the needle.
Similar letters and figures of reference are used to represent like parts in all
the figures
"
To carry out our invention we proceed to arrange on the front rail A of the
machine in suitable brackets a a sliding shaft I of a suitable length and dimen-
SIOBS to run nearly the whole length of the frame and adapted so as to raise and
lower the falling bai B "Figure 3 to the several heights required, brackets 2
are arranged at intervals on the top of said sliding shaft 1, which communicate
with the falling bar spindles c and star boxes & for the purpose of making slack
or easy courses in either the tuck or plain course when Knitting a tuck fabric.
The brackets 2 have secured theicto adjustable points or fingers 3 stepped as
follows the lower step 3 when under the star spindles e causes a slack loop to
be made for fleecing the fabric, 3° for making a plain course, 3° a tuck course, and
3d an easy course both in tuck and plain work. Upon one end of the said sliding
shaft is secured a link 4, connected to lever 5 "Figure 1,' the latter is carried ou
a spindle 6 in the bracket 7, the upper part of said lever caries a roller 8, which
impinges against the cam 9 on the rear side of the cam or time wheel 10, said
time wheel receiving its motion from a pinion 11, see dotted line Figure 2, secured
on end of the main shaft D thus when the roller is not riding on the cam 9, the
falling bar B is in its ordinary and proper position for ordinary kuitting, but when
sand roller mounts the cam 9 the sliding shaft is moved to traverse so that the
highest step 3 (is under the star spindles) of the adjustable points or fingers of
which there are six for the whole of the frame, or more or less as the case may be;
in tucking the fabric, when the roller is coming down the incline of the cam 9,
the spring 12 brings back the sliding shaft, after the can 9 has passed from under
the roller 8, consequently all rising notions of the falling bar are carried out
by the cam 9 and all lowering motions by aid of the spring 12, thus the sliding shaft
traverses exactly the distance desired to make the necessary loop such as
a short

page_text: loop to take the slack thread away from the tuck stitch," and also to bring the
lead and Jack sinkers to their higher, lower or outward positions, as the case-
may be.
To produce the loops necessary for a floecy inside face on a tucked, plain, or
tucked and plain fabric I employ the sliding traverso bat 13 which is carried in
bearings 14, secured to the back tail E of the frame, attached to the outer face
of the time wheel 10 is a cam o tack 15 and in connection therewith is b
1oller 16, attached to the truck and lever 17 working on axle in bracket 18, to
the said lever is attached the link 18" having its other end connected to the
shaft or bat 13, both the cars 9 and 15 are of the desired length so that the
distance of the traverse of the front and back shaft in each alternate course of
kutting, and thoughout the whole knitting operation is properly regulated
according to the size and number of the teeth in the time wheel 10. The sliding
traveise bar 13 carrios forked levers 16 engaging the rollers 17 working upon the
upper part of the "sınall" piesser, "large" sinking, and locking cams (but are
only shown in the drawings in connection with the right hand side cam of Figure 1,
although another set of such contrivances are likewise secured in a corresponding
position on the other end of the frame). The levers 16* are secured to supports 26-
which are loosely mounted on the bar 13 and are protected by collars 18
Attached to the sinking cams are additional cams 19, the shape of which, and
of the ordinary cam Fagiee except, that the cam 19 is cut down to a shorter
curve at the outer point 19 "Figure 4" and prevents the frame sinking during
the fleecing of the fabric. The link 20 is governed by the roller 20^ on end of
fork 21 which is attached to lever 21 rigidly secured to and the movement thereof
controlled by the sliding bar 13, when the roller 20 shifts from the cam 19 to the
cam F, the link 20 connected to the bracket 21", brings the frame down in the
ordinary courses, and when the rollers 17 shift from off the presser cams G,
the presser is chucked out of gear for the fleecing course, the link 24 becomes
inoperative, and the sinkers are moved to the head of the needles "as seen in
dotted line Figure 6." The upper ends of the links 24 are secured to the presser
bai and the lower ends to the outer end of the bracket 23*, carried on the spindle 23,
from the bracket 22 secured to the front rail A of the frame. The rollers in.
shifting from one cam to the other cause the different notions to the frame,
whereby different lengths of loop are obtamed, shorter or longer as the case may
be for the purpose of producing the desired length of fleece. The locking cam 28
18 fitted to the ordinary frame cam H, and corresponds in shape in all particulars
except at the part 28, the extension of the cam 28 causes the jacks and sinkers
to lock up at the head of the needles and leaving the loop thercou for the fiame
to come over in the ordinary way without pressing it off.
"
In fleecing the fabric or causing loops to be made to form the fleece, a slack
course is made in place of an "easy course the sliding shaft 1 is shogged so that
the step 3 comes directly under the star spindles 6', this is regulated by the time
wheel 10 in every four or eight courses, or more or less as may from time to time
be requisite.
In making a "ringwood" tuck fabric automatically without fleecing, the falling
bar shaft is brought into requisition to make the plain course in such fabric an
easy" one to avoid jagging holes therein by reason of the amount of power
required to bring the tucked work over the needle beards.
"
It will be well understood that the herein before recited letters of reference, refer
to ordinary parts in rotary frames, but the figures represent the contrivances used
in accordance with our invention.
Having now particularly described and ascertained the nature of this inveu-
tion and in what manner the same is to be performed; wo declare that what we
olaim 18-
In power driven rotary kuitting frames the employment of a time wheel receiving
its motion from a pinion on the main shaft, and rollers and trucks in connection.

page_text: therewith attached to links and governing the traverse of the front and back shafts
carrying stepped points or fingers engaging with the star spindles of the falling
bar, and forked levers, rollers and trucks in engagement with the ordinary sinking,
presser, power and locking cams, and the auxilliary cams secured thereto of the
shape illustrated. The whole in combination for producing what is known as
"ringwood tucked fleecy fabrica" automatically in the manner and by the means or
their equivalents as hereinbefore described and set forth.
