IMPROVE- MENTS IN KNITTING MACHINERY
Year: 1884

page_text: I AMBROSE BREWIN of 70 Russell Street, Loughboro in the County of Leicester
Machine Builder do hereby declare the nature of the said Invention for IMPROVE-
MENTS IN KNITTING MACHINERY to be as follows:-
The invention is applicable to knitting machinery for producing, full fashioned
ribbed hosiery, ribbed tops or ordinary plain work.
For producing full fashioned ribbed hosiery I employ the ordinary "frame"
needles and "machine" needles to which the usual motions are given and in
combination with the same I employ an improved narrowing machine which is
also constructed and operated in a similar manner to the ordinary narrowing
machine except that, according to my invention in addition to the ordinary
narrowing points which acting to take the loops off the "frame" needles and after
traversing a certain distanco, deliver them again to such needles.
I fix to the bar carrying such narrowing points a row of hook or other shaped
narrowing points which act to take the loops off the "machine" needles and after
traversing the required distance to again deliver such loops to the "machine
needles."
These ordinary narrowing points and the extra narrowing points are each
provided with an eye as is well understood and they are fixed to their bar in such
a position with relation to each other that when the ordinary narrowing points are
in a position to take the loops from the "frame" needles, the extra narrowing
points are also in the position to take the loops from the "machine" needles.
I also according to my invention operate the jack sinkers and the dividing
sinkers by independent means, and I employ an improved form of jack and novel
means of connection between the jack and sinker.
For this purpose I dispense with the rivet usually connecting the jack with its
sinker and I form the head of the sinker with a nib to work within a suitably
shaped fork, formed on the head of the jack which parts are so shaped as to
permit of the required motions, of the jack and sinker. It is evident that the
fork may be made on the sinker and the nib on the head of the jack or other
equivalent fittings may be used in lieu of the arrangement above described. The
dividing sinkers are formed with projections which are acted upon by a dividing
bar operated by a cam and suitable connections to give the required motions to the
dividing sinkers. The jacks work on the usual rod or axis but instead of forming

page_text: the jacks with holes to fit such rod or axis I form them with a fork or opening in
the undersides thereof in such manner that they can be readily and separately
placed in position on the rod or axis and removed therefrom without dismounting
any but those which are required to be removed, and instead of forming the tail
ends of the jacks with projections for the springs to act upon I form such
projections just over the axis of the jacks.
I also according to my invention connect the "slur cock" bar and the "falling"
bar by suitable arms to a rocking shaft operated at the required times by a cam
and suitable connections so that when required the said bars can be simultaneously
raised or lowered to produce, either a stiff or a slack course as may be required. 1
I also use three thread carriers as heretofore to produce the two sides of the heel
and the instep and I employ other throad carriers as may be required to produce
stripes and other effects. By throwing the narrowing apparatus out of work
ordinary ribbed tops may be produced and by throwing the "machine" needles out"
of action ordinary plain work either fashioned or not can be produced as is well
understood.

I AMBROSE BREWIN of 70 Russell Street Loughboro in the County of Leicester,
Machine Builder, do hereby declare the nature of the said Invention for IMPROVE
MENTS IN KNITTING MACHINERY and, in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
The invention is applicable to knitting machinery for producing full-fashioned
ribbed hosiery, ribbed tops or ordinary plain work.
For producing full fashioned ribbed hosiery I employ the ordinary "frame".
needles and machine needles to which the usual motions are given and in com-
bination with the same I employ an improved narrowing machine which is
also constructed and operated in a similar manner to the ordinary narrowing
machine, except that according to my invention, in addition to the ordinary
narrowing points which act to take the loops off the "frame" needles and after
traversing a certain distance deliver them again to such needles, I fix to the bar
carrying such narrowing points a row of hook or other shaped narrowing points
which act to take the loops off the "nachine" needles and after traversing the
required distance to again deliver such loops to the “machine "needles. These
ordinary narrowing points and the extra narrowing points are each provided with
an eye as is well understood and they are fixed to their bars in such a position
with relation to each other that when the ordinary narrowing points are in a'
position to take the loops from the "frame" needles the extra narrowing points
are also in position to take the loops from the "machine" needles.
I also operate the jack sinkers and the dividing sinkers by independent means
and according to my invention I employ an improved form of jack and novel
means of connection between the jack and sinker.
For this purpose I dispense with the rivet usually connecting the jack with its
sinker and I form the head of the sinker with a nib to work within a suitably
shaped fork forined on the head of the jack which parts are so shaped as to permit
of the required motions of the jack and sinker.
The dividing sinkers are formed with projections which are acted upon by a
dividing bar operated by a cam and suitable connections to give the required
motions to the dividing sinkers. The jacks work on the usual rod or axis but
instead of forming the jacks with holes to fit such rod or axis I form them with a
fork or opening in the undersides thereof in such manner that they can be readily
and separately placed in position on the rod or axis and removed therefrom without
dismounting any but those which are required to be removed and instead of forming
the tail ends of the jacks with projections for the springs to act upon I form such
projections just over the axis of the jacks.

also according to my invention connect the "slur-cock" bar and the "falling"
bar by suitable arms to a rocking shaft operated at the required times by a cam
and suitable connections so that when required the said bars can be simultaneously
raised or lowered to produce either a stiff or a slack course as may be required.
I also use three thread carriers as heretofore to produce the two sides of the heel

page_text: By throwing the narrowing apparatus out of work ordinary ribbed tops may be
produced and by transferring the "machine" loops on to the "frame" needles and
throwing the "machine" needles out of action ordinary plain work either fashioned
or not can be produced as is well understood.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical cross section. Figure 2 is an end view of a knitting machine
with my invention applied thereto. Figures 3, 4, 5, 6, 7, 8, 9 and 10 are various
views of parts thereof and Figure 11 is a cross section of some of the parts drawn
full size.
A is the framing of the machine, B is the driving shaft which is provided with
the usual driving pulleys B¹, hand wheel B³, and spur pinion B³. C is the cam
shaft on which is fixed a toothed wheel C¹ which is taken into by and receives
motion from the pinion B³. a are the frame needles which are as usual cast in
leads a fixed to a bar a². This bar is carried by arms a³ pin jointed to the ends
of levers a fixed on a shaft or axis a³ on which are also fixed other arms or lovers aⓇ
which at their lower ends are acted upon by cams a' to give the to and fro motions
to the frame needles a. The bar a is supported by and runs on rollers a³ carried
by arms a fixed to a shaft a¹0 which at the required times is operated by a suitable
cam and connections (not shown) to raise the front of the needle bar for pressing
after which it is again lowered for knocking over the work as will be well
understood.
bare the machine needles which as usual are cast in leads b' which are fixed to
a bar b. This bar is fixed to arms b³ which are pin jointed to the outer ends of
levers b* mounted on a shaft or axis 6' and which at their lower ends are acted
upon by cams 6º to give the necessary up and down motions to the machine
needles b.
The bar 6 bas also pin jointed thereto links 6' which are also pin jointed to the
ends of levers 68 fixed on a shaft or axle 69 on which are fixed other levers 610
which are acted upon by cams 611 to give the necessary backward and forward
motions to the machine needles b. When the machine needles are not required to
work they are kept out of action by depressing the levers b' and by locking such
levers in their depressed position by means of a catch b¹ (shown more clearly at
Figure 10). I would here remark that I make no claim to the parts above
described as the motions given to the frame needles a and to the machine needles b
are of a similar character to those heretofore given to such parts.

In combination with the parts above described I employ an improved narrowing
machine which is constructed and operated in a somewhat similar manner to the
ordinary narrowing machine and of which the following is a description. c, c*, a
two rods or bars on which are fixed the "boxes" c' carrying the ordinary narrowing
points c² for acting in combination with the frame needles a, and, according to my
invention, other narrowing points c³ of a hook or other suitable shape to act in
combination with the machine needles b. The narrowing points c³ and are each 4
provided with an eye (shown by dotted lines in Figure 11) as is well understood
and they are fixed to their bars in such a position with relation to each other that
when the ordinary narrowing points care in a position to take the loops from the
frame needles a the extra narrowing points c³ are also in position to take the loops
from the machine needles b. The bar c carries those points o³, c³ which act at one!
selvage of the width or widths of fabric being produced in the machine and the
bar c* carries those points c², c³ which act at the opposite selvage. The following
is the method shown in the drawings in which I give the required end way traverse
to such bars c, c*.
On one end of the bar c and on the opposite end of the bar c*, are fixed two
adjustable collars c (see Figure 5) by which the said bars c, oº are each connected

page_text: to a forked bracket or arm c³ fixed to a slide c which is at the required times
caused to slide in suitable guides formed in or on a bracket A¹ fixed to one of the
end frames or standards of the machine. An arm or bracket c' fixed to the slide c
is provided with a nut within which the screw c³ works and by which motion is
given to the slide c and consequently to the bar c or c* connected therewith.
On the axis of each screw c³ is fixed a ratchet wheel which at the required
time is acted upon by and receives partial rotary motion from a clawker or driver clo

The necessary motions towards and from the work are communicated to the
bars c. c in the following manner.
The bars c. c* are mounted in arms c¹7 which are fixed to a shaft c18 carried in
the upper ends of lovers clo. These levers c¹ are fixed to a rocking shaft c" to
which is fixed a lever c which is operated by the cam ¹³.
The necessary up and down motions are communicated to the bars c. c* in the
following manner.
To the shaft c¹s levers c" are fixed, such levers have pin jointed thereto links or
connecting rods c" which are connected to levers 2 mounted on a stud or axis c*
and operated by a cam c". And in order to enable the narrowing machine to be
thrown in and out of action when required I connect the link or connecting rod c²
to the leveres in the following manner. The lower ends of the links or connecting
rods care formed with forks c to pass over studs fixed to the levers 25 and to
the connecting rods care pin jointed notched plates c20, thus by raising or lowering
the links or connecting rods and by moving the notched plates on their axes so
as to place the studs in one or other of the notches the links or connecting
rods are securely fixed to the levers in the required position to permit the
narrowing machine to work or to keep it out of work.
d are the jack sinkers the head of each of which according to my invention I
form with a nib d to work within a fork d³ formed on the head of the jack d²,
which parts are formed and proportioned that the upper arm of the fork d³ shall
in depressing the jack sinkers d'act centrally of their width whilst the curved
form given to the inner faces of the arms of the forks cases the motion and in
event of wear of the parts facilitates adjustment as the forks d³ can be readily
brought to the required distance apart by means of suitable dies and tools. The
jacks d work on the usual rod or axis d', but instead of forming the jacks d³ with
holes to fit such rod or axis I form them with forks or openings d³ in the under-
sides thereof in such manner that they can be readily and separately placed in
position on the rod or axis d' and removed therefrom without dismounting any
but those which are required to be removed and instead of forming the tail ends
with projections for the springs to act upon I form such projections de just over
the axis d' of the jacks d².
The springs fare cast in leads which are fixed to a bar f' carried by short arms
or bosses ffixed to a rocking shaft ƒ³.
On this shaft f³ is also fixed a lover f' which is acted upon by a cam f³ by
which means the pressure of the springs ƒ is applied to or removed from the jacks ďª
at the times required.
c, are the dividing sinkers which are formed with forward projections e' which
are acted upon by a dividing bar e a locking verge or bar e adjustably fixed to
such dividing bar e', and standing over the tops of the jack sinkers in front of the
jack heads is employed to facilitate the regulation of the loops as by raising or
lowering the said verge or bar e the jack sinkers may be permitted when the
dividing sinkers are depressed, to rise a greater or less distance above such dividing

sinkers or if required be retained at the same level. The dividing bar e² is fixed
to the lower ends of arms e' which are pin jointed to arms or levers e" fixed to
shaft or axle 66 on which is also fixed an arm or lever 67; the outer end of this
arm or lever e² is by a link or connecting rod e³ connected to a lever e³ which is
mounted on an axis and is acted upon by a cam e" by which the required
motions are given to the dividing sinkers e. The dividing bar e³ is guided in its
up and down motions by spring bearers e fixed at one end to such bar e' and
resting at their other end upon the face of the bar g within which the sinkers d, e,
work or it may be otherwise guided.
are
h is the "slur cock" bar and i is the "falling" bar which according to my
invention I connect by arms 11 to a rocking shaft to which are also fixed levers
which at their lower ends are provided with trucks or rollers adjustably mounted
thereon and which rest upon sliding arms ♬³ formed with three planes at different
levels in order to enable the machine to produce either a stiff or a slack course
when required as also the ordinary character of work. The sliding cans
mounted on one of the front horizontal bars connecting the two end standards of
the machine and are provided with rollers' to facilitate their motion and such
cams are connected together by a bar j* which is at the required times noted
upon, by the upper end of a lever to move the cams j³ in the one or the other
direction. This lever is mounted on an axis carried by a bracket A³ fixed to
one of the standards of the machine, the lower end of this lever j³ is forked and it
is provided with two rollers 77 which are acted upon by cams or tappets * fixed to
or formed on a ratchet wheel mounted on a stud or axis 10 carried by the
bracket. This ratchet wheel is operated by a driver j¹² carried by the lower
end of a lever which is mounted on a stud or axis and is provided with a
truck or roller 15 which is acted upon by a cam 11.
The falling bar i rests in brackets which by means of screws i³ are adjustably
fixed to brackets h¹ fixed to the slur cock bar h.
k. l. m. are thread carriers which are fixed respectively to sliding bars k l m²
working in brackets A³ and such sliding bars ' ' m² are adjusted and operated in
any well known or suitable manner to cause them to traverse a longer or shorter
distance according to the number of needles required to produce the width of
fabric for the time being made in the machino. is the locking bar which is
carried by arms n¹ fixed to bosses * fixed on the rocking shafts n³ and such
rocking bar is operated by means of a cam n¹ which acts upon a lever n³, fixed to
the rocking shaft n³..
o is the machine slide which acts to knock over the work on the "machine"
needles, such slide is fixed to arms o' which are pin jointed to levers of which
latter are fixed to a shaft o³ which is operated at the required times by a cam and
suitable connections (not shown) as is well understood.
p is a bar of hooked or other shaped points which I employ in the process of
transferring the loops from the "machine" needles to the "frame" needles when
it is required to produce plain work after having produced ribbed work; this bar p
is fixed to arms p' pin jointed to levers carried by a suitable shaft and such shaft
is operated by cams and suitable connections in such manner as to give the
necessary backward and forward motions and endway traverse to the point bar p.
I have not thought it necessary to show the mechanism for producing the
movements as such will be readily understood. The bar p and arms p¹ are shown
by dotted lines in Figure 11.
The action of this bar of points p is as follows. When it is desired to transfer
the loops from the "machine" needles to the "frame" needles the bar p is caused
to approach the "machine" needles so as to carry the points through the loops on
such needles, a slight endway traverse is then given to the bar p so as to distend
the loops sideways, the "frame" needles then advance and enter such loops the
points, retire and the "machine" needles rise and press off the loops when the
latter will be held by the “frame” needlės.
