CIRCULAR-WARP-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 397,142, dated February 5, 1889. Application filed April 30, 1888. Serial No. 272,300. (No model.) Patentedin England February 8, 1886, No. 1,834.

To all whom it 71mg/ concern.:

Be it known that we, llnNnv BLAcKFoRD PAYNE and WILLIAM OAMPION, both oi' Nottingham, England, have invented certain new and useful Improvements in Circular-larp- Knitting Machines, (for which we have obtained English Patent No. 1,854., dated February 8,1S86v.) of which the following is a specification.

The object of our invention is to so improve circular-warp-knitting machines that they may be worked much faster than the ordinary straight traverse warp-machines.

The invention consists in the details of improvement and the combinations of parts, that will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part of this specification, in which- Figure l is a central vertical cross-section of a knitting-machine embodying our invention. Fig. 2 is a similar view of the upper portion of the machine drawn on a larger scale. Fig. 3 is a partly-broken horizontal section on the plane of the line c c, Fig. 2, on an enlarged scale. Fig. t is a detail top view of part of the machine, and Figs. 5 and 6 are detail sectional views showing the guide-rings in different positions with relation to the needles.

In the accompanying drawings, the letter A represents the frame of our machine, which 'may be of suitable construction.

a is a block or step held on a base-plate or otherwise suitably supported in the frame A.

B is a vertical standard or shaft firmly secured in the block or step u orotherwise held in place.

b is a sleeve or tube that. surrounds the lower part of the standard B and carries the main driving-pulley d, that receives a belt from suitable source for rotating said sleeve or tube. The said tube rests on a step, u., as

shown.

e is a sleeve that fits loosely over the tube l), and is free to move thereon, and is supported as hereinafter shown. The sleeve e carries a series of radially and upwardly projecting arms or supports, f and f w,wh0se upper ends extend inwardly, as shown. The supports f and fl are held in position or braced near their upper ends by rings f f1, that are secured to said supports and surround the 1nachine, as shown in Fig. l. Part of these arms, f, we term inner and part, fw, outer supports. The forked ends of the inner supports straddle the outer circumference of and carry the lower guide-ring, D, and the outer supports, flo, straddlc the outer circumference of and carry the upper guide-ringLD. Each of these guide-rings carries on its inner circumference a series of thread-guides, D?. rlheseguide-rings D and D are supported in the armsfandfm, respectively, and are capable of revolving or turning in said sup ports and to move up and down with them. They receive their rotary or oscill atory motion as follows: The lower guide-ring,D,carries on its under side an annular ack, g, that meshes with a worm, 7i, j ournaled on one of the inner supports, f. The axle of the worm 71. carries a pinion, i, that gears with a raclgj, on an upwardly-extemling lever, Z. The lever Z is pivoted to a rodym, that slides in bearings n, carried by the inner support, j. The rack j is held in gear with t-he pinion i by means of a spring, o, that is secured at one end. to the lever I and at 'its other end to the sinker-ring E, hereinafter described, or by other means. '.lhe rod m` is drawn downward and pressed upon a pattern-wheel, q, by a spring, p, that is secured at one end to the rod m and at its other end to a bearing, n, or by other means.A The circumference of the pattern-wheel q has proj ecting studs or protuberances fw. The wheel q is placed around the sleeve e, and is free to turn thereon.

The pattern-wheel q receives rotary motion as follows: ris a gear-wheel fixed to the sleeve b, and which gears with a pinion', s, journaled on an arm, t, that is carried by an inner arin or support, f. The pinion s carries a number of pins, u, that engage a toothed wheel, fu, which is fastened to t-he pattern-wheel q.

As the gear-wheel r rotates with the sleeve b,

the pattern-wheel q, through the pinion s, pins u, and wheel if, will be rotated. The studs w on the pattern-wheel q thereby act with the spring p to raise and lower the rod m, and with the saine the lever l and rack j, thereby IOO Lla

turning the worm 7L and advancing the lower guidc-ring D, in the desired direction. The rack is lnoved out l gear with the pinion 'L' when desired, so as not to actuate the guidering D during one movement ol' the rack j, by means of a pin, fr, on an arm, "y, ot' a series that support the sinker-ring E, which arms receive up-and-dmvn motion, as hereinafter shown. As said arm 1/ descends the pin a; strikes the lever l and moves it outward, thereby disengaging the rack j and pinion As the arm i/ rises and removes the pin ir from the lever Z the raekj is drawn into en gagement with the pinion t' by the spring o, so that the pinion may again be turned by the next longitudinal movement of said lever.

Instead of securing` the pin :I: to an arm, y, it may be attached to any other appropriate vertically1'eeiprocating part of the machine.

At or near the lower end of the lever l is a i rack, z, that gears with a pinion, c2, journaled on an inner support, j'. On the axle ol' the pinion o2 is secureda worm, b2, that gears with a toothed wheel, d2, which is hung loosely on the sleeve e, its boss resting on the boss of the wheel q1 below it. The wheel d2 carries on suitable projecting arms, e2, bobbins or other warp beams, f2, the threads g2 from which pass upward and over a rod, h2, suitably supported by the lower guide-ring, D, to the guides D2 on the guide-ring D. As the-lever l and rack .e are rcciprocated by the patternwheel q and spring p, the wheel (Z2, carrying the threads g2, will be turned in unison with the lower guide-ring, D, the rack e' being thrown in and out oi:` gear with the pinion t2 in manner similar and at the same time to that described with reference to rack ,j andA pinion 'i'.

The upper guide-ring, D', is rotated or oscillated substantially in the manner shown wit-h reference to the lower ring, D, but, on account ot its position, with a li'ew slight changes in detail. rlhe following is the 1nanner of rotating said upper guide-ring, D: Upon the sleeve l) is secured a gear-wheel, '22, that gears with a pinion,j2, on a shaft, Z2, jour naled in bearings in an outer support, fw. The shaft Z2 carries a pin-wheel, m2, the pins of which mesh with a toothed wheel, n2, sceured to astud or pattern-wheel o2, that is loosely hung on the sleeve c, its boss resti ng on the boss of the support 1"0 below it. The studs p2 of the pattern-wheel o2 engage a rod, q2, that slides in bearings r2, carried by the outer support, f1". This rod q2 is drawn inward and held against the pattern-wheel 02 by a spring, s2, that is secured at one end to the rod q2 and at its other end to a bearing, r2, or otherwise. The outer or free end of the rod q2 is jointed to a lever, t2, that is pivoted at u2 to the outer support, f1". To the upper endol' the lever t2 is jointed a lever, r2, that extends inward and carries a rack, 102, that meshes with a pinion, x2, journaled in an extension, y2, of the outer support, Fig. 4t.)

fw. (See On the shaft ol the pinion :r2 is l l i l l l cured a worm, E2, that gears with an annular rack, c", on the upper guide-ring, D'. The lower end ol the lever t2 is also jointed to a lever, h", that carries araek, d", which engages with a pinion, e, journaled in the outer guide-ringl support, fl". (')n the same shal't with the pinion e" is a wmfimf", that gears with a toothed wheel, q", hung loosely on the sleeve e, its boss 'resting on the boss ol'l the wheel o2 below it. The wheel g carries in suitable arms, 7i", bobbins or warp-beamsf2, from which the threads Q12 pass ujjnvard and over rods Z", that are carried on the ring D', and then ce to the guides D2on the upper guid e-ring, D. As the rod (fis moved intermittently by the pattern-wheel o2 and spring s2, the lever r2 and rack u'2, through the lever l2, will bc moved to turn the pinion 1:2 and worm .2'2 to advance the upper guide-ring, D'. the lever 2 is moved as above, it will also draw on the rod b" and rack d" to turn the worm j, and thereby rotate the wheel y", carrying thc warpthreads (,112, in unison with the upper guide-ring D.

The rac U12 and d are moved out of' gear with their Vrespect-ive pinions r2 and c, so as not to turn the upper guide-ring, D', and wheel gfon one stroke ol' said racks by means of adj ustable pins or projections vm", carried by the pattern-wheel o2, that bear at intervals upon the inner en d ot' the lever h" and depress said lever, thereby moving the rack LZ" out of gear with the pinion cf. The lever h" i eonnected to the outer end of the lever '2:2 by means ot' a rod, `n, which pivoted at its ends to said levers. As the lever h is depressed by thepinsfml, the rack a2 on the lever 'r2 will be elevated and moved out of gear with the pinion by the rod n" (lrawing down the outer end of the levcrr2. ',lhe lever if' is raised to throw the rack d" and pinion c" into gear by a spring, o", secured at one end to the lever if* and at its other end io the rod q2. As said lever b" is raised, the rack `m2 will be lowered Vthrough the action of the rod n" on the lever r2. lily the above construction, ali'ter the worms ,z2/"1 have been turned to move the upper guide-ring, D', and wheel g" aroundin position to lap the threadson theneedles, the racks v'm2 d" can be thrown out ot' gear with their pinions and pnt in position to again move said guide-ring and wheel in the direction desired, and the motions are repeated; but the rack '11;2 could remain in gear with its pinion (r2, and the combined actions oli' the pattern-wheel c2 and spring s2 through the levers q2, t2, and lr2 would reciprocate the rack 102, and thereby move the upper guide-riilg, D', foward and backward similarly to that shown with reference to the lower guide-ring, D. Thus it will be seen that as the sleeve b rotates the guide-rings D D' and their spoolwheels cl2 and g are moved around the machine in the desired direction, or the guiderings are moved backward and forwanl in position for lapping the needles.

All the parts supported by the outer sleeve,

TOO

from the outer supports, f1, are a number of rods, s, that are preferably guided at their lower ends in fixed sockets ss. Certain of these pendent .rods s'l carry rollers t4, that run upon the cam-surfaces of afwheel or disk, c",

secured to the sleeve l). As said disk c" is rotated by the sleeve l), the cam-surfaces, acting` on the rollers t", raise the supports f, sleeve e, and connected parts, the weight of the parts holding the rollers t on the camwheel r4. By this cam-wheel r4 the sleeve e and the parts it carries are supported. (lertain of the rods s" have springs url coiled around them, which act to cushion the parts carried by the sleeve e.

From. the foregoing description it will be seen that the guide-rings D Dl receive an upand-lown and a rotary or backward-and-forward motion,.while their supportsfw merely receive an up-and-down motion, that the pat-v tern-whet-ils receive an up-and-down motion in unison with that of the guide-rings, and also a rotary motion to impart rotary or backward-and-forward motion to the guide-rings, and that the bobbin-wheels d2 y" receive an up-and-douui motion in unison with the guiderings D D', and also a rotary or a backwardand-forward motion in unison with said guiderings, so as to keep the threads ina straight line with the guides through which they pass.

Having shown how the guide-rings D D are operated, we will now show how the needles, presser-bar, and sinkers are operated. rlhe standard B carries a number of outwardly and upwardly projecting arms, a, upon the upper ends of which arms is placed a ring, bi. The arms a may be in one piece or in separate pieces connected together. The ring b5 carries a circular ledge or rim, d5. In a recess in the rim (Z5 is vlaid and suitably supported a continuous wire, Upon this wire the lower hooked ends of the needle-jacks F rest. 'lhese hooks are held upon the wire e by a plate or plates, lf2", screwed ou the rim rflf" and projecting over the ends of the hook ends of' the ,jacks F, as shown clearly in 2. There may be any number of these jacks F desired placed around the machine in series. Each needle-jackF carriesone,two, or more needles, g5, that are cast in the jacks or secured thereto in other suitable manner. The upper ends of the needle-jacks F are held in position by means of a ring, 71,5, that is carried by arms t5, that project from the yto the sleeve h.

standard B. The under side of the ring h5 is provided with radial grooves, in which the upper ends of the needle-jacks F rest, and by which said needle-jacks are guided. The needles gi receive an in-and-out or longitudinally-rcciprocating motion, as follows: Each needle-j ack F has a projecting inclined arm,

j", that passes between blades or plates l, that are adjustably secured to circular rings ym,

carried by arms n, that project from the standard l5, which arms slide freely on said standard. rlhe blades d are arranged above and below the arms and in contact therewith. To certain of the arms h5 are secured pendentrods o5, that are guided in the arms a, and that carry at their lower ends rollers that ride upon cam-surfaces Q5 on the upper face of a disk or wheel, G, that is secured The rods o5 also carry rollers fr", that bear upon counter-cams s, carried by said disk Gr.l As said disk G rotates, the rods o, through the cams qi 3",will be reciprocated,

thereby raising and lowering the arms a5 and blades Z5. As these blades Z5 are thus raised and lowered, they will, by acting on the inclined armsf, rock the needle-jacks F on their wire or pivot e, thereby movingtheneedles gl in and out toward and from the guide-ringsl D D.

The needles gf' pass through the suikers tf", that are secured to the circular sinkcr-ring E, that is carried by the arms y. These arms /y extend from the standard B and slide freely thereon. From certain of the arms 1/ depend rods u, that are guided in the arms a, and that carry rollers r", which bear upon cams ur" on the disk G. As the cams yuff* rotate with said disk, the rods fui will. be reci procated, thereby imtnlrting down-and-up motion to the arms y, sinker-ring E, and sinkers tf.

Extending from the standard B, and sliding freely thereon, are a series of outwardly and upwardly proj ecting arms, a, that carry at their upper ends a ring, h, to which isr secured the presser-ring H. Depending from certain of the arms a6 are rods d, that are guided in the arms a, and carry at their lower ends rollers e, that bear upon camsf6 on the disk G. As said cams fG are rotated with the disk G, the rods d will be reciprocated, thereby imparting up-and-down motion to t-he arms a and the presser-ring H, for pressing the beards of lthe needles.

ln order to relieve the weight of the parts carried by the arms 07.5, ab', and y we attach to those arms '725, a, and ly that do not carry the rods o5, u, and d springs I, that are secured at their opposite ends to supports g5, carried by the standard B. le prefer that every alternate arm n, u, and y should carry a rod, the others connecting with the springs. By this means the parts are nicely balanced. The fabric from the needles passes upward to a roller, J, j ournaled in bearings in the frame A, which roller may be tu rned by suitable means. (Not shown.)

This circular warp-knitting machine oper- IOO ates in making' t'abric as follows: The n eedles g5 first move outward or forward about half their length into position to receive threads, while the `guide-riugs l) l) are both above said needles, as in l `i` 'lhe guide-rings D 1),being' supplied with threads, then turn in the direction desired t'or a certain distance by means ot' their respeeti ve pinions and 1"", worms thereon, racks] and trg, and parts con nected therewith. The `guide-rin. rs then descend through the action ol' the sup1i orts f and parts connecting' same with the cam LV* until they are beneath the needles, as in Fig'. ti. 'lhe guide-bars then move in the desired direction ln'n'izontally the proper distance, and are then moved upward again by the cam ufl and su pjlj)ort's fw, when the threads will be properly lapped on the needles. The needles then move farther outward or torward to pass the laps well over the beards onto the shanks ot' the needles. The needles then return, bringing' the laps under their beards, and just as the beard-points enter the sinkers if the presser II rises and presses the beards into the c ves or grooves oi' the needles, the needles continuing in their backward or inward movement. Then the ends of the needles get aligned with the nibs of the sinkers, the sinkers fall sufficiently te permit the needles carrying the laps to pass inward ot the nibs or points oi' the sinkers. The nee` dles then enter with their ends the back part or knockingevcr part oll the sinlcers sutticiently to draw a proper length of loop, the thread lying' in part across thc face of the knocking-over part. The sinlcers then move upward and secure the loops in the arch of the sinkers, preventing' the loops trom tollowing the needles in their next outward movement. These movements are then repeated.

For makin g some kinds otl fabric itivmaynot be necessary to rotate both the `sg'uitlcbars at once, as one may be stationary while the other moves, or one maybe moved in one direction and the other in the opposite direction, or both may remain stationary at any moment, if desired.
