To all whom, it may concern: I

Beit known that I, HENRY ARTHUR BETT- residing at Carlton, in the county of Nottinguseful Improvements in Knitting-Machines, ofwhich the following is a specification.

This invention relates to improvements' in fitted with bearded needles and bladed -knit tingswhecls, the object of the present invention being the provision of improved means by which a splcingfthread may be inserted and any predetermined needle and at any particular course, .means by which the splicingpositio'n' for any-number of courses or parts of courses,` means for cutting thetliread and holding the cnt end when the thread is thrown' out otaction, and means for automaticallymechanisms. i

The splicing thread-carrier mechanism shown ,in Figs.- i, 5.and 6 is arranged relativelyto the'machineas shown in Fig. 1,'and

bya bracket 2.0i, the usual descriptionr and 1 the needles'similarlytobladed' wheels 'of the ordinary description. Attached to the bracket lis a -plagte`3, to which'the Ii'xed cutter 4.v is

connected bya spring 5.] On the inner side of the plate there is tted a slide '6, to which in Fig. i).

are attached., 4The slide 6 is fitted with pins 9, which slide in slotsfand is actuated by a lever 10 from the splicingdhrcadcarrier axle 5 5 11. .The lever l0 is pivoted at l2 on a bracket 13,'which is carried by the same piece 2 as lheboss of the lever -14: is 6o moved' by its guide 17 into the position shown 65 The carrier 17 is iirmlyfattached t0 the axle ll, which is also fitted with a lever 18,'provided with a truck 19 and a. spring 20 for holding the truck in contact with th cani-truck lever The number of needles in theki'iitting-head indst be exactly divisiblev by the number of blades iii the wheel l, and as the splicingthread is thrown into and out of action at 'opposite ends of a diameter of this wheel the 7 5 number of needles upon which a splicingthread slaidmust bc equal tohalf the number of blades in the i'vheelor some odd multiple of this number. The shape 0f the blades at which the thread is thrown into and 8o At blade a thread is 85 thread is moved across the blades until it enf ters the groove in blade g, which is the first .blade to lay the thread on the needles. The

blades 71 and i then guide the thread to the 9o usual knitting position, as shown on'bladej. vThe row B shows the shape of the blades at ywhichthe thread w' is thrown ont of work. The thread is moved Afrom the knitting position shown on,blade 'o' to the groove in 95 blade c', whiclris the last blade to lay the threadV on the needles. The thread is then moved overthc blades f',- g', @gland t until it is out of work inthe position shown relatively to the.bladej.

the movable holder 7 and vmovable cutter 8 Fixed toV the machine group of knitting-wheels there is a splicingl wheel and thread-carrier, which are fitted as already described. The cam-truck 19 on the lever 18 is-h,cld by the spring 2() in contact with a cam truck lever 23, which is fulerumedV at 24 and. fitted with a truck 25, which is held in contact with the cam 2G when the splicing apparatus is at workby the springr 2O through the lever 1S. The length of the raised portions of the cam 2G corresponds to the length of the unspliced portions of a course,- and as the cam 26 revolves with the needle-cylinder the splicing-thread is thrown in and out of action, according to the number of rises on the cam.

The mechanism for holding the splicingthread out of action altogether comprises a catch which prevents the lever 23 following the cam 26.

The catelilever 40 is pivoted at he under side of the frame 27 and is provided with a pin 42 for holding the level' 23 out ol" action. The lever is also connected to a'ring 23, which is capable of a limited eircular motion which is obtained from the pattern-chain This pattern-chain is carried by a'donhle-ilanged wheel 33, which is at- 1 tache-d to a ratchet-wheel 34. On the same axle there is another' ratchet-wheel 35 with the same number of teeth as the wheel 34, and fastened to the wheel 35 there is a third ratchet-wheel 36, having one tooth for every four teeth in the wheels 34 and 35. rPhe ratchetwheels are actuated by a lever 238, which is fulcrumed at 3f: and operated by a cam 39 on the needle-cylinder. The lever is iitted with two clawlrers 37 and 137, the formeracting upon the teeth of the wheel 35 to rotate the same and the wheel H, which is fastened lthereto. The clawker 37 is used for operat ing the wheel 3l and. the connected chainwheel 33 and acts upon the vhecl l-t once in every four oscillations of tle 'lever 13S. For the other three oscillations the clawker il?" is t held clear of the wheel 34 by the wheel lili, l uponwhlch it rests. The wheel 134 is thus operated one toothat' every four revolutions of the needle-hem]` and a short pattcrn-chaiu is used; but an ordinary ratcl'iet-whecl arrangement with a longer chain may be used, if desired.

The rimr is fitted to .move on the under side of -thc frame 27 am. near the patternchain` 'is fitted with an adjusting-screw 2i), which is held in Contact with the lever-arm 30 by means et" afspring 30". The other arm i 3l rides upon the chain 32 and when raised by a pattern-picce held in its 'raised posiltion by a catch 33 unl..l another piece strikes l the catch 35i and releases the lever 31, which allows of the ring:r to ne moved by its spring. The movements giveri tothe ring 28 are timed to take place when the raised part of the cam 26.1 is opposite the lever 23, the splicing mer-hanism being thus thrown into and out of work without a jerk.

In a machine fitted with two or more fceders and spilt-,ing the same portion of each i cutters and holder,

course it is necessary that the splicing-thread shonld'be thrown into action atthe same needle. To enable this to be done with the saine mechanism, the lever 23 is made with a hooked end, as shown at Fig. 3, and the outer end of the lever 40 is which areplaced between pins 44 on the ringr 28. This arrangement may be used with all the splicing mechanisms, and when this is done the pattern-chain may be actuated at any part of the revolutionof the needle-cylinder. Thering 28 is moved as already explained, and when moved in the direction o the arrowA43 the spring 45 is placed in tension, but is prevented from moving the lever 40 by the hook on the Iend of the lever 23. When, however, the-raised Ipart of the cam comes opposite the lever 23, it raises the saine sufficiently to allow of t-he spring the lever 40 clear ofthe lever 23. lVthen the ri n g 28 is moved in the opposite direction, the lever 40 is moved into a position to hold up the lever 23, and when this is raised `by the cam 26 its hook is forced past the pin on the lever 40, which is then moved under the hook by thespring it'.

rlhe number an'l arrangement ofthe splieintr-thread lmechanisms to each head may be varied. Thus in a threefeedcr headV splicing three different portions ot' the same course the splicing-threads be thrown into and out of action simultaneously. splicing two different portions of thesame course the splicing-threads mayv bethrown into and out of` action in pairs, the cam 26 having two raised portions.

When the herein-described mechanism is in operation and the splicing-thread lis to be thrown ont of action, the Cain 2G, through the levers 23 and l5, moves the carrier 17 from its knitting position, Fig. S, to the position shown in Fig. E) andl the thread is moved between the which thenommence to move. The thread is lirst trapped by the holder 7, Fin'. 10,-and is afterward severed by the cutter 8, Fig. ll. When thethread is thrown into actlon,`it is lirstinoved to' its knitting position and then released from the holder, the loose cud being guided by the guide 2l".

In addition the machine .is filled with the usual knittingwheels, thread-carriers, ywork rollers, and other usua-l mechanisms.
