T0 ALL WHOM IT MAY CONCERN:

Be it known that l, ARTHUR PAGET, of Loughborough, in the county of Leicester, Kingdom of Great; Britain, manufacturer, have invented e nenf and nseiul improved Knitting Machine; and I de hereby declare the following to be a full, clear, ond exact description of the some, reference being had to the accompanying drawings, and to the letters of reference marked theiweon.4

The improvements comprised in the present invention for knitting or manufacturing looped fabrics, consist,

Firstly, in method of and arrangement for using s snlier to each needle, and actuating cach sinkcr consecutively by an incline or other mechanical eqoiulent acting directly upon such sinlrers; also in n method of and arrangement for supporting the sinkers in e. grooved bar or comb on each sidctoi` the part on which the inciine or other mechanical equivalent acts; also in a. method of and arrangement for retaining euch Sinkel" in position by a. spring` which also assists the action of the sinker when sinking the thread Secondly, in s method of and arrangement for using a presser-bar with geits or grooves for tbe sinkers to slide through, the Wells of such goiis or grooves being made to press the needle-boards.

Thirdly, in an arrangement for drawing across the incline, or other equivalent, by a doubled-grossed pulley revolving with thc 'main shaft, and by cords or chains, and weights or catch-blocks, so arranged as to draw `cross once dur-ing a; port ci'Y each revolution, andV in opposite directions clair-ing each alternato revelation ourthly, in n. method of suspending the action of the drawing-across motion by the emplyment of an incline or cam-piece, so arranged that when required it can he mede to lift a. hinged incline piece, or other mechanical equivalent, and thus prevent the catch-block entering the notch in the drawing across pulley, by which the said catch-block would otherwise he carried round.

Fifthly, in a method of producing a. seit'ege'in any part of the width of the frame by the cinpioyrnent of su ilicline, or other mechanical equivalent, attached to and traversing with the incline for actuating the sinkersor their" equivalents; by which first-mentioned incline the thread-layor or thread-loyers is or are made to descend and pass between the needles at the end of each course.

Sixthly, in a. method oi' making the knocking-over bar with the knocking-over pieces of steel plate, or other suitable material, and of securing them in gaits or grooves in o bar oi' brass or other material.

Seventhly, in a method of alternately knitting web, und narrowing or widening the some, or making changes in the knitting by moving endwiso in the direction of their axes the set oi coms or levers employed in @ducting the narrowing, widening, cz' changes in the knitting.

Eighthly, in a method of producing. by n self-noting motion, (in which coms, incines, or levers, can be usoth) the before-mentioned endwise movements ol' the cams or levers, which scid self-acting motion cnn be (without arresting the revolution of the cams) brought into op'craticn by hand. or by tappeti'. or holes in on endless chain, beit. drum, or pulley.

The following description having reference to the accompanying sheets of drowings, and to the letters and figures marked thereon, will enable competent persons convex-sent. with knitting machinery to fully understand, make, #incluse the heforemientioned several parte of my invention.

In this machine there are iivs primary parts Vemployed in producing the fahricLthe remaining parts being for the purpose ofY actuating the said tive primary ones. These are, first, the needle A, which is of the ordinary kind. :ind of which there nre as many as the wales required in the fabric; secondiy, the thread-loyer B; thirdly,

the sinliers C, the number of which is one more than' that oi' the needles; fourthiy, the presser D; and liftiily, the knocking-over bar E.

In order to render this explanation more distinct, I will first describe how the ve primary parts oet upon the thi-end sc :is to produce thc fabric, and afterwards describe the paiticnlor parte in which my invention consists.

To make the fabric, o piece of work, x, is rnn on to the needles A, Figure 5, drawing No. 2, and pushed bock on their stems to behind thh sinkers C. A thread y, is threaded through the threaddayer B and attached to the end needle the presser-bar D is cleared of the needles; the knccking-over bar E is stationary, and has in its upper edge a series of grooves in which slide the needles A; the thread-layer B traverses along the needles eres@ nf C', while the catch-block or Weight C1n will be hanging down below the pulley Cm by its cord C9, which `.vill lic in the groove C2i. When the pulley Gli' revolves, the notch or indentation in its outer periphery will tuke round with it the catch-bleek C, drawing with it the cord C andthe slide C in the direction of the righthund end of its traverse. The cord C will slide in the groove C2i, in the opposite direction to the revolution of C', and it will he seen that before the catch-block Cl" roaches the outer periphery of C1, the notch in it will have passed the point Where Gm comes in contact with CH; therefore es Cl continues its revolution, C will slide in the groove C14 in the opposite direction to the revolution of Cw. When the pin CScomes in Contact `with Cl, the throwing-out picos C will more outwards, us hcreinhefore described, und thereby disengnge or throw out the catch-block or weight CE2 from the notch in Cl, when Cm will bythe action of its own weight hong down, as Cl did at the commencement of the movements. (il will non' have been drawn across to the rightha-nd ond of its traverse, and C be et the same portion of the periphery of C at which ("2 was at the commencement of the movements. As Cl again maken its revolution, the notch will nonT take the catch-bleek Cl und the cord and dran' across C7 in the direction of the leftdiund end of its traverse, (see Figures l, 2, and 8.) The catciebieek C 'will non', as before described, miss the notch in C, and slide in the groove C to its former position, and when CT has reached the right-hand end of its trnrorse C" will disengage Cw in the manner hercinbefure described. Thus the slide CT, with the incline und other parts attached to it, will he drawn across in one direction or the other once during u portion of oooh revolution of the pulley.

C is the incline or cum-piece, which muy be employed for suspending the notion of the drawing-aereas motion, and is formed upon or secured to the lever C2i, having its fulcrum at Cgi'. In the position of the parts as shown in figs.f 1 and?, the drawing-across motion will act in the ordinary manner, that is to soy, the catch-block C will bc caught by the notch in the pulley C, and carried round with the policy, es hereinbefore explained. When it is desired to suspend the notion of the drawing-across motion, the incline or cam-piece C26 is moved by means of the lever C2x into the position shown in dotted lines in iig. 2. In this position its edge will, during the revolution of the pulley, come in Contact with the pin C, and will thereby raise the hinged throwingmut pieee C, thus lifting the cntclvblock Ci2 and causing the notch in the drawing-across pulley to pass the catchhloek, and thus suspending the action of the drawingmcross motion as required. It is evident that as long as C25 is retained in this position the action of the drawing-across motion will remain suspended, but when C25 is caused to resume its fermer position, then in the next revolution of C' the drawing-across 'notch jwill carry with it the catch-block, as before described.

I will new describe the arrangement `and action of the thread-layer and incline actuating it. B is the thread-layer or tube, (provided with suitable holes for the purpose of receiving the thread and delivering it to tho needles,) und it is attached to or formed with a. slide, B', which slides vertically in suitable guides or a groove formed in the slide Bi, supported by and free to move horizontally in either direction along the fixed bar B", which may be part of or secured to the bar for supporting the siukers, as hereinbofore described, or muy be secured te the framing in anyothcr convenient or suitable ina-nner, as is Well known to makers et' knitting machinery. The slide B may be moved along the bar Bi by spring-clips I, or any suitable method which will allow C" aud B to continue their trarersc and to pass over and beyond B3 and Bl, when B3 und B shall he stoppedby any methods many of which uro well known to makers of knitting machinery. The slide C7 in the present case'also carries the thread-layer incline BE for the purpose ci acting (in its passage across the frame) upon the upper ond of the `.iertical slide B, and thereby pushing it downward and causing the threaddayer B to descend and pass between the needles A, when the horizontal threaddayer slide di has its motionierrested, and the inclines C* and B6 pass it. It is thus evident that u selvedgo may be produced on euch edge of the web, as by the ordinary tubular thread'layers in general use, und the thread-layer B can he lifted to its former position, (after or whilstthe course is knocked over and completod,) by a. rocking-shaft, I4, levers, I5, und bar, I, or in any other convenient and suitable manner, asis Well understood by makers ot knitting machinery. It will also bc seen that two, three, or more thread-layers caribe put into action in the sume manner and on the same bur, und actuated by the saule incline, each thread-layer being arrested at such spot as may he required.

Z represents the shaft or axis of the various come employed respectively for knitting wel); and narrowing or making changes in the knitting, und G n. tube, tting upon and revolving with the shaft, but capable of being moved endwise thereon, as hereinafter explained, or by any other convenient or suitable means. The cams G1 G2 G3 Gr4 G G6 and G7 (if G9 are formed with or secured to the tube G. The series of clams G2 G* and G5, (colored rech) aotuote the levers G G12 Gl* andG" for the purpose of knitting rieb. For narrowing, widow ing, or otherwise chonging the knitting, the tube G may be moved endwisc upon the shaft, into the position shown at Figure 1G, so us te bring into operation the series of cams Ga G5 G und G, colored blue. The cani Gis T.vill non' cetuate thc lever Gn which uns previously operated by the cam G2, the com Gfs will operate the lever G previously actuated by the cam Gi, and the cams GY and G9 will operate the levers G's and G, und the nam Gl will operate the lever G not previously in motion, the motions of some levers boing thus altered while others are thrown out of action. i

It may easily be seen that the seme result muy be attained hy the equivalent act of moving all or part o the levers simultaneously endwise, instead of the coms es described; alseythat thc number and shape o'i the cams for either the ordinary knitting, or the required narrowing, widening, er changing the knitting, muy he varied es the said chungo may require; and the said loyers muy be so adopted by rocking-shafts, or other convenient or suitable means, to actunte any kind er arrangement of ilerices for narrowing or widening, or to netuate a second set of needles for making ribbed work, or any other arrangements for making changes in the knitting, as is well understood by makers of knitting machinery. It will also be seco that a third or more sets of earns and levers may be applied, so as to effect other changes in the knittingg if requisito. It will also be seen that the ports may be so constructed that only one or more cumsmey be moved endwise at once, if required.

For the purpose of e`ccting by a self-acting motion tho before-mentioned cndwise movements of the cams, the following-described devices may bo used: H represents an endless chain or belt, passing over the pulley Hl, and having an intermittent or step-by-stcp motion communicated to it, in the direction of the arrows, by any convenient or suitable means, as is woll understood by makers of knitting machinery. To the chain or belt H are secured tappcts, H2, se as to raise. (when the endwise movement of the cams is required,) the lever H which has .its axis or f'ulcruni at H", and at its end the helicoidal or screw-shaped segment or incline Hu. Another arm or branch of the lover H has at its end the helicoidal segment oi' incline H7, inclined or screw-shaped in the contrary direction to H5, or, (as will perhaps be hotter understooth) the two inclines heilig right and left handed. Z represents a portion of the shaft or axis of' the cams, and G a portion ofthe tube carrying the cams and requiring to be moved endwise. The tube G has formed uponor secured to it the arm G", the projeetion Grla of which passes through a notch or recess formed in the ond of the driving-arm Gg, secured to the shaft Z. In the position of the parts, a3 shown, it is evident that when the arm G" and tube G shall be caused to revolve with the shaft Z by the driving-arm G, the position endwisc of GIT and G will remain unntected by either oi' the inelincs H5 or H7, as neither of them will como in contact with any part of G" or its projection G. When, however, the lever II* is moved, either hy hand or by the action of one of the tappets IP, so as to bring the inclines Hr and IlT into the position shown in fig. 10, the end of the projection G" will in its next revolution come in contact with the helicoidal odge of the incline H", and be thereby slided cndwise, carrying with it the arm G" and tube G, into the position shown in tig. 1U. The inclines H3 and H7 will afterwards, while in this position, continue out of action, and allow the arm Gr'T and tube G to revolve without being affected in their position endwise on the shaft Z, but immediately upon the lever H4 and inelines Il and H7 resuming their` original position, the edge oi' the projection G will he acted upon during its next revolntionby the helicoidal edge of the incline H7, which will cause G, G'S, and Gto move endwise to their original position, in which they may continue to revolve clear of both inclines until the lever H* shall be again moved.

Il; is obvious that a drum having tappets or holes, and caused to revolve in a suitable lnanner, may be substituted i'or the endless bolt or chain and tappets herein described, and that the arrangements may be otherwise modified in various ways without departing from their distinctiveprinciples.

Having now fully described and ascertained the nature of my said invention, and the manner in which the same may bperformed, I would have it understood that without confining or limiting niysclf'to the precise details represented, inasmuch as the some are capable of being variously modified without departing from their distinctive features, I claiml l. The method of and arrangement for retaining` each sinlcer in position by a spring which also assists the action of the sinlter when sinking the thread.

l2. The combination of the hars (13D, and the sinlters C, when the whole are constructed and operate in connection with each other as set forth.

3. The arrangement for drawing across the incline, or other equivalent, first in one directian and then in the other, by a doublegroovcd pulley revolving with the main shaft, und by cords or chains, and weightsl or catclnbloclts, so arranged as to draw across once during a part of each revolution.

L The m'ethod of suspending thc action of the drawing-across motion by thc employment of an inclino or cam-piece, so arranged that when required it can be made to lift a hinged incline piece, or other mechanical. equivalent, and thus prevent the catch-bleek enteringr the notch in the drawing-across pulley, by which the said catch-block would otherwise be carried round.

5. The method of producing a selvedge in any part of the width of the frame by the employment ot' an incline or other mechanical equivalent attached to and traversing with the incline for actuating the sinkers, or their equivalents, by which iirst-montioned incline the thread-layer or thread-layers is or are made to descend and pass between the needles at the end of each course.

6. The plates El of steel orvothcr hard metal, in combination with the bar E, as described.

7. The method of alternately knitting web, and narrowing or widening tho same, or making changes in the knitting by moving cndwise in the direction of their axes tho set of' cams or levers employed in knitting the web, and another set or sots of cams or levers employed in effecting the narrowing, widening, or changes in the knitting.

8. The method of producing, by a sclfacting motion, (in which cams, inclines, (l1-levers can he nseih) the before-mentioned endwise movements of the cams or levers, which said self-acting motion can he, (without arresting the revolution oi' the cumin) brought into operation by hand, or by tappcts or holes in an endless chain, belt, drum, or p'ulley.

9'. I further claim as my invention, and desire to secure by Letters Patent, each of lheFort-going methods or arrangements, in combination with any or'all of the other methods or arrangements.

In testimony whereof I have signed my name to this specification in the presence ot' two subscribing witnesses.
