I, WILLIAM HARRISON of 128 Portland Street, Manchester in the County of
Lancaster, and 67 Oxford Street, London, Patentee and Manufacturer, do hereby
declare the nature of this invention to be as follows:-—
"
This invention relates to improvements in knitting machines of a description
similar to those known as the "Harrison" parallel bed knitting machine, the "Star
circular knitting machine, or other form of machine in which tumbler or latch
needles are used, and worked either by hand, foot, or power: and the object of this
invention is to obtain a more varied style and quality of work with an increased
production.
In machines constructed according to this invention intended to be worked by foot
or hand, I attach a wheel at or near the end of the frame. I connect this wheel to
the cam carriage by means of a link secured to the wheel by a stud, and to the cam
carriage by a rod or other suitable means. I fit the cam carriage either into slots or
upon rods placed on the upper part of the needle bed, or on the angle of the needle
bed, and such slots or rods may constitute the sole bearing of the cam carriage. To
obtain foot motion I employ a treadle connected to the machine either by band
or rod.
When power is employed to work the machine, I place a fast and loose pulley on
the driving shaft. I cause the machine to stop automatically when required for the
transfer of loops for widening or narrowing in the fashioning of stockings, gloves,
jackets, and other kinds of clothing. To obtain the automatic action for this purpose I
attach to the driver a clutch, friction pulley, or other similar appliance. I form the
adjoining portion of the driving shaft with a flat surface, or a key groove, and upon
this portion of the shaft, I place a corresponding clutch, friction pulley or other
appliance to this sliding clutch or friction pulley I attach a swing lever or link, and
chain or band which I pass over a pulley and join to a slide bar or plate, fitted so as
o slide in either direction, and forwards or outwards; or upwards and downwards.
form the bottom of this slide bar of an angular shape. In a convenient position,
TD 1

page_text: near the slide bar I place a counter shaft, on which I fit a boss or pulley with a soud
or projection attached: the slide bar is free from contact with the revolving stud or
projection except when, according to the form or shape of the article being manu-
factured the machine is required to be stopped, which is effected by means of studs
acting on the aforesaid angular slide bar, the said studs being attached to a chain 5
formed of square plates. I arrange the distance between each of the said studs
according to the required shape of the work in progress. When the chain is caused
to revolve by passing over a pulley which bears against the slide plate and actuated
by a pawl and ratchet wheel, each of the studs in turn presses the slide plate outwards;
the revolving stud or projection on counter shaft striking against the angular part of 1
slide bar or plate causes tension on the chain by which it is connected to the clutch
or friction pulley and the clutch or pulley by these means drawn back and out of
gear and the machine is thus stopped. In a modification of the above arrangement,
I place a worm on the driving shaft, and in 'suitable positions near the said shaft I
place a series of pinions of different diameter: according to the speed at which the 1
work is required to be performed, one of these pinions is caused to work, by being
actuated by the worm on driving shaft, the smaller pinion being used for the quicker
speed, and the larger pinion for the slower speed. On each of these pinions a stud is
fixed of an eccentric form which when the wheel or pinion to which it is attached
is working, the said stud acts on a vertical or horizontal shaft. At one end of this
shaft is a lever which being raised causes the lever swivel to push the machine out of
action and the work is stopped.
In order to facilitate the formation of the heels of stockings, gloves and similar
articles, I put any needle out of action in different parts of the needle bed, while the
loops remain on the needles, by allowing the cams to pass over the needles without
actuating them either up or down. To effect this I form the heels of the needles so
that they may be level or nearly level with the surface of the bed. I form slide
springs to clip the under and upper sides of the bed. At one end of the spring I
make a short bend to act as a hook or grip to hold the needle: the open part of the
hook is made to fit over part of heel of needle which is cut down to surface of needle
bed: the bent or hook part of needle spring is pushed up and tilted over the short
heel of needle, the spring being united by the short heel of needle fitting into the
bend or hook spring: the hook part of spring projects above the surface of bed of
machine, while the upper and straight part, which is a continuation of the hook, rests
at the bottom of needle groove: the spring hook acts as a grip and also as the heel of
the ordinary needle so that when the cams come in contact with the projecting hook
of the spring, the needles are caused to ascend and descend same as the ordinary
needles. The spring slides up and down with the needle, and also holds the needle in
the required position, while acting as a needle stop. When any needle or any number
of needles are required to be put out of action, they can be released or unhooked by
pressing down the bottom of hook spring in an angular direction, which causes the
hook part of the spring to tilt up over the short or cut heel of the needle, and thus
disunites them; the hook spring is then drawn out of the way of the cams, and the
cams pass over the short heels of the knitting needles without coming in contact with
them; the disengaged needles thus remain in any part of the bed with or without
the loops of the knitted goods, while the remaining needles are in action and other
parts of the work proceeding. To facilitate the tilting of the needles I round the
underside of the spring or needle stop gib or bar.
When it is required to form by hand a stripe with one or more colours, I place a
column or pillar at a convenient part of the machine preferably at the end, and a
the top of column I attach a bracket. One end of this bracket has a table or box with
one or more angle slides or swivels, each pendant end of which has an eyelet for the
yarn, such eyelets being threaded with different colours of wool or other material
these angie slides are pushed backwards and forwards so that the colours may b
changed instantly without stopping the machine: the yarn guide is made with a
open worm or core so that one yarn can be released and another recaught by the oper
worm guide as it passes the angle strippers without stopping the machine.

page_text: The angle yarn feeders may if preferred be actuated automatically by a revolving
drum placed above them. Around the drum I attach studs at such distances as to
determine the number of rounds and colours of stripes to be made the drum is worked
by a pawl and ratchet wheel which is put in action by a projection actuated by the
carriage passing to and fro underneath the drum.
As an alternative motion for working the angle yarn feeders automatically I employ
a chain with jointed squares, in each of which I fit studs, in such parts and at
distances that will determine the number and depth of the stripes: by means of
projections on the passing carriage coming in contact with a slide on which is a
projection placed at the opposite end which forces up another slide, motion is given to
a wheel fitted on a shaft on the shaft of this wheel I place a pinion enclosed in a
box. I form holes in the bottom of this box, in each of which I place a spiral spring
and over each spring I place the upper end of the angle yarn lever feeder. I then
place a bar which works across them. At one end of this bar I form teeth in which to
gear a pinion wheel, thus causing the bar to move backwards and forwards: by means
of a projection on the underside of said bar, the upper end of angle yarn feeders are
pressed down causing the pendant end to stand out from the rest with the colour of
yarn next to be taken up by the open worm yarn guide, which lets free one yarn and
catches another without stopping.
In a modification of my invention I effect the same object as herein last described
by a chain constructed of rectangular pieces of leather with holes formed therein.
The holes in the chain that come opposite the ends of such of the angle yarn feeders
as are intended to be pushed out to feed the yarn are covered with thin metal, and the
holes that come opposite the ends of such of the angle yarn feeders as are not intended
to feed are left open by these means the angle yarn feeders that are intended to feed
come in contact with the metal covering over the holes in chain and are pushed out,
while those not intended to feed spring back into their places, by their ends being
allowed to fall or enter the holes in the said chain.
For the purpose of striping, I also employ two bobbins which swivel so as to leave
the loose part inside.

page_text: Improvements in Machines for Knitting Stockings, Gloves, and other
Articles, by Hand, Foot, or Power.
I, WILLIAM HARRISON of 128 Portland Street, Manchester in the County of
Lancaster and 67 Oxford Street, London Patentee and Manufacturer do hereby
declare the nature of this invention and in what manner the same is to be performed.
to be particularly described and ascertained in and by the following statement:-
This invention relates to improvements in knitting machines in which tumbler or
latch needles are used and worked by either hand, foot or power, and the object of
this invention is to obtain a more varied style and quality of work with an increased
production.
In order more clearly to describe my invention I have annexed hereunto seven
sheets of drawings. In the several views illustrated therein similar letters refer to
similar parts.
Fig. 1. represents front view and Fig. 2. end view of "Harrison" parallel bed
knitting machine.
In these views the machine is shown constructed to be worked
by hand or foot motion. On a shaft ; placed in a suitable position near the end of
frame a, I attach a wheel b. I connect the wheel 6 to the cam carriage c by means
of a rod d which is secured at one end to the wheel band at the opposite end to a slide
bare attached to cam carriage c and working in slide rest f. I fit the cam carriage c
into grooved bars or rods g: the cam carriage c rests on and slides between the bars g
and is actuated when worked by hand, by means of the wheel h which is fitted on
shaft j, or when worked by foot motion by means of belt bon wheel b and connected
with treadle 2. As an alternative method for the support of the cam carriage c
I arrange the grooved bars g in the positions shown in Fig. 3. the bars being attached
to frame a. The cam carriages c are connected to each other by a loop or saddle
piece and the grooved bars 9 constitute the sole bearing of cam carriages. In
Fig. 4 rods are shown in lieu of bars. In Fig. 5 side view and Fig. 6. end view, the
machine is represented as worked by power, and for this purpose I place a fast and
loose pulley n¹ and n² on the driving shaft n. By means of the toothed wheels o, o¹
and o motion is transmitted to other parts of said machine the cam carriage e being
actuated by the bar o to which it is attached and the wheel o³. I cause the machine
to stop automatically when required for the transfer of loops for widening or narrowing
in the fashioning of such articles as stockings, gloves, jackets or other clothing. To
obtain the automatic action for this purpose I attach to the driving shaft n a clutch K,
and sliding on a key groove on the same shaft I place a corresponding clutch K.

page_text: ""
I connect the sliding clutch K¹ to the swing lever / by means of rods 1. The swing
lever is pivotted at 12 and connected to a slide bar m by rods 13, 14 and 15. The slide bar m
I form with a slot m' and a flat angular shaped end m². I fit on shaft p a boss or pulley pl
to which a stud or projection p² is attached. When the boss p¹ revolves the stud p²
actuates the pawl attached to free end ³ of lever q. At each revolution of shaft
ม
with boss p¹ the ratchet wheel q² is propelled one tooth and with it the flat chain r.
form the chain of flat angular plates. I attach a stud or projection to some of these
plates, the number and distance between said studs being arranged according to the
required shape of the work in progress. The chain which forms an endless band
is placed on angular shaped pulley's attached to shaft t of ratchet wheel q². The
remaining and slack portion of chain is passed under loose pulley s¹ and is suspended
from loose pulley s³ which attached to frame a. The slot m¹ in slide bar mallows
said bar free movement upwards or downwards and the end m² of slide bar m is free
from contact with revolving studs or projections except when the shape of the
articles being manufactured requires the machine to be stopped which is automatically
effected by the studs when passing in their turn over pulley s striking and raising
the end m² of angular slide bar m which is simultaneously pressed down in the centre
by a stud p³ on revolving collar p¹, the slide bar m thus acts on the levers or rods 13, 14
and the swing lever and the rod l. The clutch K is by these means drawn back
out of gear and the machine is thus stopped instantly.
In a modification of the arrangement herein last described for automatically stopping
the machine, in lieu of the flat chain to which are attached the studs that act on
the slide bar m,
I attach said studs either to the outer surface or the face of the rim
of a pinion or wheel within which either a worm or wheel is geared as shown in
Figs. 8 and 9. The pinion ** is secured on shaft t in place of angular pulleys: as
the shaft t revolves by the action of ratchet wheel q² the pinion revolves with it
and actuates the wheel r causing the studs to act on the end m² of slide bar m in
the same way and with the same effect as herein previously described.
I do not confine myself to the form of clutch shown on accompanying drawings
any other description of clutch that may be preferred which will act in a similar
manner can be used to obtain the same results. In order to facilitate the
formation of gloves, the heels of stockings, and similar articles, without the
usual accessories, I put any needle out of action in different parts of the needle
bed, while the loops remain on the needles, by allowing the cams to pass over
the needles without actuating them either up or down. On sheet 5 of accom-
panying drawings Fig. 10. represents transverse section and Fig. 11. plan of part of
needle bed. In these views c' is the needle bed having grooves c², formed both on the
upper and under surface of said bed. I form the heel e³ of the needles so that they
may be level or nearly level with the surface of the bed c'. I form slide springs c
to clip the under and upper sides of the bed. At one end of the spring I make a short
bend to act as a hook or grip to hold the needle c³: the open part c³ the hook is
made to fit over part of heel c³ of needle which is cut down to surface of needle, bed c¹.
The bent or hook part e of needle spring is pushed up and tilted over the short heel c³
of needle, the spring being united by the short heel of needle fitting into the bend or
hook spring. The hook part cs of spring projects above the surface of bed of machine,
while the upper and straight part which is a continuation of the hook, rests at bottom
of needle groove c² on both sides of bed c¹. The spring hook e acts as a grip and
also as the heel of the ordinary needle so that when the cams come in contact with
the projecting hook of the spring, the needles c³ are caused to ascend and descend
same as the ordinary needles. The spring c¹ slides up and down with the needle
and also holds the needle in the required position, while acting, as a needle stop.
When any needle or any number of needles are required to be put out of action,
they can be released or unhooked by pressing down the bottom of hook spring c¹ in an
angular direction, which causes the hook part c of the spring to tilt up over the short
or cut heel c³ of the needle, and thus releases or disunites them; the hook spring c
is then drawn out of the way of the cains, and the cams pass over the short heels cof
the knitting needles without coming in contact with them. The disengaged needles

page_text: thus remain in any part of the bed with or without the loops of the knitted goods,
while the remaining needles are in action and other part of the work proceeding. To
facilitate the tilting of the needles I round the underside of the spring or needle stop
gib or bar.
XC
When it is required to form a stripe with one or more colours either by hand or
automatically I place a column or support v at any convenient part of the machine
but preferably at the end as shown in Figs. 5 and 6. For automatic action I attach
to the support va bracket w and at one end of bracket w I place a table or box w¹
with one or more angle slides or swivels each pendant end of which has an eyelet
for the yarn such eyelets being threaded with different colours of wool or other
material. These angle slides are pushed backwards and forwards in the manner herein
after described so that the colours may be changed instantly without stopping the
machine the yarn guide is made with an open worm or coil so that one yarn can be
released and another recaught by the open worm guide as it passes the angle stripers
without stopping the machine. The angle slides or yarn feeders are worked auto-
matically by means of a chain ³ formed of jointed plates in which I fit studs in
such parts and at distances that will determine the number and depth of the stripes.
I place a projection y on the travelling carriage which by coming in contact with
study attached to slide y² causes said slide to be drawn back and the ratchet wheel r
to be propelled one tooth at each traverse of the cam carriage c, by these means the
angular pulley is caused to rotate and with it the chain 3 as each of the studs at
intervals passes under end of lever ³, the opposite end of said lever is pressed
down and with it the slide ve. A stud which is attached to cam bar 8 works in a
diagonal slot v formed in slide v and the downward vertical movement of slide vs causes
the cam bar to travel horizontally and each pendant end of the yarn feeders is by these
incans caused to stand out from the rest with the colour of yarn next to be taken up by
the open worm yarn guide which lets free one yarn and catches another without stopping.
When the stripe is formed by hand I arrange studs as in Fig. 7. and the angle yarn feeders
are alternately actuated by said studs being pressed down or outwards as in Fig. 7a.
In a modification of my invention 1 cause the angle yarn feeders to be actuated
automatically by means of a revolving drum placed above them as illustrated on
sheet 6. Fig. 14 is a front view and Fig. 15 end view drawn to an enlarged scale :
around the drum s I attach studs s6 at such distances as to determine the number of
rounds and colours of stripes to be made. The drum is worked by a pawl s' and
ratchet wheel which is put in action by a projection y attached to the carriage c
passing to and fro underneath the drums. The lower part of pawl is formed to
slide vertically and is jointed at 59. At each traverse of the cam carriage c the
projection y strikes the lower end of pawls thus raising it to the position indicated
in dotted lines on drawing and rotating the drums one tooth. By these means the
yarn guides are actuated in accordance with position of studs 6. For the purpose
of striping I also employ two bobbins which swivel so as to leave the loose loop inside
the tubular work. These are shown in Figs. 16 and 17. In Fig. 16 when sufficient
rounds of one colour have been knitted I turn the wheel 2 which throws thread f³
out of action and puts thread f in a position that yarn guide will take hold of it.
For the same purpose I obtain the same action automatically I arrange the parts as
shown in Fig. 17. the ratchet wheelf and bevel wheels f being actuated by chain f
and studs working over pulley 10 the pawl f" being thereby raised at intervals
and propelling the wheels f.
I apply automatic stop motion to circular knitting machines by means of the clutch
action herein previously described for parallel bed knitting machines, adapted to
circular knitting machines as represented in Fig. 18 sheet 7.
In this view a is the frame or standard, the circular machine c and c¹ bevel gearing
for revolving machine b: a shaft n is supported by means of brackets, and attached
thereto are the driving pulley n' and the clutch K: the pendant lever is actuated by
the stud attached to disc or wheel r. the clutch is by these means drawn back out
of gear, and the machine is thus stopped instantly: the speed of the wheel or disc r
is regulated by the size of the pulley's.
