The iaiiieeCi--guiee are in theform of levers '95 i3, Wiiioi'i eie hung izo e pin i4, carried by the opper ende ofvioms l5, Whioh are secured et their lower ends to e shaft or spindle 16, momiiae eo es to be free to turn in Suitablev bearings on the bemlzxfce l, each of the bars xoo 15 having a projecting arm 17, and these arms carrying a shaft 18, to which is secured a pattern-drum 19 and a ratchet-Wheel 20, the pat tern-dro m having pins or other pattern-surfaces adapted to act upon the outer ends of the levers 13, so that the inner or thread-gnid ing end of any one of the levers may be depressedA in order to feed its thread to the needles at the knitting-point or may be elevated so as to direct its thread over the tops of said needles.

The desired movement of the pattern-drum 19 is elected in thevfollowing manner: 0n the shaft is an eccentric 21, and the sleeve of this eccentric carries apawl 22, yvhh engages with a ratchet-Wheel 23 on the hub of a pattern 4- chain wheel 24, said hub being mounted sor as to be free to turn 'on the shaft or spindle 16. Also mounted so as to be free to turn on said shaft 16, but connected so as to have no movement independent of each other, are apair offarms 25 and 26, the arm 25 projecting into the path of anv antifriction-roller 27, carried by the back of the bevel-pinion 4, and a spring 28 acting on the arm 26 in order to move the arm 25 into range of said antifriction -roller. The arm 26 is forked and' carries a hooked pawl 29, which is acted upon bya spring 30, so that its hooked end tends to move into engagement with the teeth of the ratchet-wheel 20. Projecting forwardly from the arm 26, however, is a iinger, ,ewhich isnormally in contact with therednoed central portion of a stop-lug 32, the lattenheine, pivoted, by means of a pin 33, to one of the bars and being of such Vlength as to project over the pattern-chain 34,wlii ch is mounted upon and actuated by the pattern- Wheel r24:.- Normally, thereforethat is t0 say, when the parts are in the position shown Xin Figs. 1 and 2-the arm 26 is prevented from moving forwardly, so as to cause its pawl 29 to engage with the teeth of the ratchet 2O;1b but-when the stop-lng 32 is lifted by the action of any one of a number of projections 35 on the pattern-chain 84 the finger 81 will be released from the restraining inlinence of said stop-lug and the arm 26 Will be at liberty to swing forwardly under'the action of the spring 28, so that its pawl 29 willl engage with a tooth of the ratcl1et-wheel20, and upon the backward movement of said arm 26, caused by the action of the antifriction-roller 27 on the arm 25, said pawl will move the ratchet- -pins of the pattern-drum 19, so as to move the wheel to theextent of one tooth and will thereby edect a change in the position of the operative thread-guiding lever into inopen' -ative position and move an inoperative threadguiding lever into operative position,ti1e stoplng 32 dropping in front of the finger 31 as soon as the support of the projection is removed, so as to retain the parts in operative relation to each other until further change in the position of the thread-guides is desired.

Secured to the projecting end of the shaft or spindle 1G is ahandle 36, by means of which said shaft may be partiallytnrned in its bear,- i'ngs, seas to cause the bars l5, with the'levers 13 yand other parts earriedthereby,to be 7o swung away from the needle-cylinder, in order to permit of the removal of said cylinder from the machine and the insertion of a new cylinder in its place.

A rWeighted arm, such as shown by dotted 75 lines in Fig. 2, or some other, available form of retainer may be employed for holding the bars 15 andthe parts carried thereby in op erative relation with the needle-cylinder.

Various means of mounting .the thread. 8c

et We have illustrated one such modification 85 in which the threadguiding leversl 153il are hung to a' pin 14:, carried by a forked frame 3*/,which has pins 38, adapted tobearings in fixed standards or brackets 39 on thefhedu plate 1, said'frame also carrying the shatter 9o spindle otlthe pattern-drum 19S and having a handle 41, lwhereby it may be conveniently raised or lowered, so as to carry the thread-guides from or. toward the'needle-cylinder.

In order to prevent the threads running'.

from those gu ldes which are outof action from. catching upon the needles, we use a needle shield or guard consisting of a bent plate 45,

which incloses the needles on each 'side of the rec point at which they' arel raised l by the knit-` tinivcams in order to'receive. the knittingthread, said bent plate le5 being clit away at .that point', so as to Ipermit threadvte be fed to the needles from any one of 4the guides 13 x05 which is depressed, the thread from the elevated guides, however', asthe needle-cylinder rotates beingso directed by the shields or guards v as to'pass over the tops of the raised needles, with which'said threadsare no thus prevented from conflitti?,s into engagement. The shield filas a projecting stem 46,which may be mounted upon the bars 15, as shownl in Figs. land 2, or -npon any other desired part of the movable thread-guide carrier, so I I5 as to be moved out of the waywith the ythreadguides when it is desired to remove or insert the needle-cylinder..

Having thus described our invention, we

claim and desire to secure byLetters Patrco ent- 1. The combination in a knitting-machine,- ot a rotatable and removable needle-cylinder, with thread-guides movable into and out of operative relation with' the needles, and also xav movable from and toward the needles so as to permit of the insertion or removal of the nee- (lle-cylinder.A 2. A knittingmachine in which are combined n. rotatable and removable needle-cylinder, thread-guides movable into and out oi operative relation `with the needles of said cylinder and also movable' to and from the needl'ewylinder ecce to permit o the lineen tion and removal of the same, and a pattern devioe acting on said thread-guides and movable toward and from the needle-cylinder With the same. u

3'. A knitting-machine in which are oombined a needle-cylinder, a rotatable earrier therefor having a split and tapered ange engaging with the inner side of the needleeylindor and an annular Wedge rotating with said carrier and acting upon the split and tapered iiange of the same.

LA knitting-machine in which are oomll bmed a `needle-Cylinder, a rotatable carrier having a split and tapered flange adapted to engage with the inner side of said cylinder, an annular Wedge engaging with said split and tapered flange, and an annular nut engaging with said annular Wedge. and bearing upon said rotating carrier.

5. A knitting-machine in which are oombined a rotatable and removable needle-cylinder, a series of thread-guides, a patterndrum for acting thereupon, a pivoted strueture carrying said thread-guides and drum, and operating mechanism for said patterndrum hung upon the same axis as the carrier therefor.

U. The combination in a knitting-machine, of a series of thread-guides, a pattern-drum for aeting thereupon, a ratchet-Wheel eonnected to said drum, a swinging arm having a pawl for engaging with said ratchet-wheel, a movable stop-lug for arresting the movement ot said pawl-oarrying arm, a pattern- '.ohain for moving said lug, and means for aetnating said pattern-chain and swinging arm.

7. A knitting-machine in which are com- 7 bined a rotatable needlecylinder, thread guides movable vertieallyinto and out of operative relation with the needles, and a needle shield or guard covering and protecting the tops ofthe needles on eaeh side of the knitting-point,whereby the thread from a raised guide will pass over` said shield.

8. A knitting-machine in which are oombin ed a rotatable needle -eylinder, threadguides movable -vertically into and out of operative relation with the needles, and a needle shield or guard covering and protecting the tops of the needles on each side of the knitting-point, whereby the` thread from a raised guide will pass over said shield, the latter being out awayso as to escape the needles when the latter rise to receive the thread from the operative guide.

9. A knitting-machine in which are cornbined a rotatable and removable needle-cylinder, thread-guides movable vertically into and outof operative relation with the needles, a needle shield or guard for preventing the thread'from a raised guide from engaging with the needles at the knitting-point, and a carrier for said thread-guides and needleshield movable so as to carry them away from `the cylinder in order to permit of the removal of the same.

In testimony whereof we have signed. our names to this specification in the presence of two subscribing witnesses.
