STRAIGHTHKNI'TTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 397,141, dated February 5, 1889. Application filed March 31, 1888. semi No. 269,104. (No model.) Patented in England June '7, 1886, No. 7,646.

To all whom it may concern.- I Be it known that T, HENRY BLACKFORD PAYNE, of Nottingham, England, have in.- vented Improvements in Straight-Knitting Machines, (for which I have obtained Letters Patent of Great Britain, No. '7 ,616, dated June 7, 1886,) of which the following is a specification.

The object of my invention is to provide certain new and useful improvements in knitting-maehines.

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

I5 Reference is to be had to the accompanying drawings, forming part of this specification, in whicl Figure 1 is a front elevation of a knittingmachine containing my improvements. Fig.

2 2 is a vertical cross-section on the line 0 c, Fig. 1; and Fig. 3 is an enlarged detail front view of a portion of the machine shown in Fig. 1.

' Certain parts of the machine shown in Fig.

2 are left out in Figs. 1 and 3 for the sake of clearness.

In the accompanying drawings, the letter A represents the frame of the knitting-machine, which may be of ordinary 0r suitable 3 construction.

B is a cam-shaft journaled in suitable bearings in the frame A. This shaft may be driven by means of belt and pulley or other suitable gear.

a is a handwheel shaft journaled in suitable bearings in the f rameA, which shaft carries a hand-wheel, b. ries a pulley, (Z, from which a belt passes to a pulley, e, on the cam-shaft B, whereby said hand-shaft o is made capable of turning the shaft B when necessary.

f is the needlebar rock-shaft journaled in suitable bearings in the frame A. Upon this shaft f are secured a number of levers, g,

which support the needle-bar 72, upon which needle-bar the needles i are secured in suitalole manner. The levers g preferably each have an opening through which the camshaft B passes. The levers gcarry suitable roll- 5 ers or contact-pieces, j, that bear upon cams The shaft to also car-- D on the cam-shaft B. (See Fig. 3.) As the cam-shaft B rotates, the cams D will impart motion to the levers g to reciprocate the needles i.

Zis the sinker-bar rock-shaft journaled in suitable bearings in the frame A. This shaft Z carries a number of levers, m, upon one arm of which levers are secured sinkers n in such position that the needles 2' may pass through them. The levers on also carry rollers or contact-pieces 0, that bear upon suitably-shaped cams E on shaft B, whereby reciprocating motion is imparted through the lovers m to the sinkers n. In suitable beai ings in the frame A is hung the presser rock-shaft p, upon which are mounted a series of levers, g, which levers q carry the presser 'r in such position as to engage the beards of the needles 2'. The levers q also carry rollers or contact-pieces s, that bear upon cams F on the shaft B, whereby reciproeating mot-ion is imparted through the levers q to the presser r.

The above arrangement of parts may be altered to suit the requirements, such parts forming no part of my present invention, be-

ing shown more particularly to illustrate my improvements.

I will now show the arrangement of my improvements for operating the guide-bars.

In suitable bearings in the frame A is jour- 8o naled a rock-shaft, G, from which extend a number of levers, f. The levers are preferably arranged vertieally, as shown. Near the upper or free end of these levers z is a rockshaft, to, that passes through the levers t. Intermediate short levers, t,also preferably extend from the shaft u upward parallel with the levers t, as shown in Figs. 1 and 3. To the shaft u are secured a number of links, t, that extend toward the needles 1', as shown in Fig.

2. At the upper or free ends of the levers t t are journaled a series of links, w, that extend about parallel and in the same direction with the links '2). Through the free or inner ends of the links 2? passes a shaft, x. (See Fig. 2.)

H are guide-bar brackets that are journaled at one end to the shaft :1; or to the links 1;, and at their opposite or upper ends these brackets H are journaled to the links 20. The brack- IOO ets H support and carry in suitable manner the guide-bars I, that are in proximity to the needles I. The links 1' and '11 are connected by links 1:, that reeeive and support rods Over which the 1hreads o'- pass to 1l1e guides. To the rook-shaft (1, that carries 1 he guide-barsupporting levers are secured two (more or less) lm'ers, 1 'lhesehsvers 1 extend to the cam-shaft l5, and carry rollers or eon1actpieees 12', that bear upon cams .l' on said shaft. As said canrshalt l3 is rotated, the shaft (t, by means of the levers 11 and cams J, will be rocked, thereby acting, through the levers to move the guide-lawsl from and toward the needles 1'; but it is evident that other means may beemployed for moving the guides toward and from the needles in the direction of their length. Theguide-bars I reeeive a lateral or up-and-down motion in a straight line as follows: To the shaft .1 are secured one or more pendent levers, (1 whose lower ends are pivotally connected to levers L, that are preferably hungupon the shal't /i These levers I) extend from the shaft j" to the canrshalt B and carry suitable rollers or contact-pieces, If, that ride upon suitable cams, M, on the camshaft .ll. As the (i-aneshali't l is rotz'lted, the levers L, through the lovers act upon the brackets ll to raise and lower the guide-bars I. At the same time the guide bars are moved inward by the lovers y and 1, which :niovement acts 1:0 compensate for any radial movement given the guide-bars by the lever (1*, and by this means the guide-bars are moved. substantially in a straight line to lap the threm ls. By this means, also, the guides, while lapping the threads, are kept at one depth in 1he needles.

The guide-bar I 111ay receive longitudinal or endwise nn'ition by suitable means; but I prefer the l'ollowing arrangement: To one end of each guide-bar I is secured a rod, 12 that is connected. at its opposite end to a lever, journalcd on the frame A, there bei 11g one rod (1 and lever e for each guide-bar l. The rods (Z are pr Ferably secured to adj ustable draw-bits f carried by the levers e whieh draw-bits f have set-screws g that bear agzlinst the levers 6 but the guide-bars I may be secured directly to the levers e .lly the above means the guide-bars I may be adj usted longitudinally to bring the guides in 'n-oper position with relation tothe needles '1'. The lowerorl'rw ends of the levers e bear upon suitable pattern or out wheels 7L2, that are carried by a suitable shal't, F, journaled on the :lrame A. The shaft also carries a worm-wheel, This worm-wheel 7' is engaged by a worm, P, on the ca1n-shaft B. As the shaft 1 3 rotates, the worm liworking in the worm-wh eelj rotates the shaft and thereby the pattern-wheels If, which, acting upon the levers e actuate the guide-bars I. To the opposite ends of the guide-bars I are secured springs M which s n'ings are attached at their opposite ends to the frame A or a pro jection thereon. The springs 11/ act to draw the guide-bars .l and to keep the levers e" pressed upon their res 'leetive pattern-w]1eels 71 in the ordinary manner. This manner of operating the guit'le-bars l longitudinally is shown and fully deseribed in an applieation for a ]')atent 111ade by me, filed January 21, 18811, Serial No. 1912138, and I refer tosaid application for a more detailed deseri 1tion.

()nly part of eaeh guide-bar l is shown in the drawings; but it will be understood that these guide-bars extend across the machine and are supported and guided in the braek.- ets ll. 'lhese bars I are broken away in the drawings tor the sake of ehiarness.

In l'ront ot' the 111aehine the neeessary beams 11'' for the threads (1 are arranged and suitably supported. The threads 0 pass from the beams 11 over suitable tension-rm'ls, p suitably carried by the frame A, and thenee over the rods to the guides and needles 1'.

The fabric N, when 111ade, passes upwarl'l to the roller r that is mounted on a shaft, .9 ('rarried by the frame A. A drum, is hung on the shaft s and earries a pawl, a thatengages a ttmthed wheel, r. by means of a cord wound on the drum 1" and a weight secured to the cord (not shown) the roller isrotated; but any suitable means may be employed for turning the roller '1' to wind the fabric.

llaving shown the arrangenmnt of the different parts and how they are given their respective motions, T will :now show how the machine operates to make fabric. The threads being in )osi1 ion and the parts ready for op eration, the machine is started. The needles 1 are :lirst moved [tn-ward sullieiently far to allow the guides to lap the threads around the needles, which is done by the guides moving first, say, longitudinally through the aetion of the levers e and pattern-wlreels 713*. The guides then move, say, downward through the action ol. the lovers a and L, the guides again movinglongitudinally and then upward by the action of the levers o and L to thefirst; position. The threads are now lapped on the needles. The needles 1' then move forward toward the guides to their full extent to pass the laps 011. the needles under the beards. The needles then move backward, and just as the beards of the needles enter the sinkers n the presser r moves and presses the beards of the needles into their respective eyes. The IlOWllOS then continue to move lmekward sutficieutlyin the sinkers to enable the last loop formed on the needle to be knocked over, the sinkers then moving down and up to secure the last loop made under the nibs of the sinkors. As the needles 2 move backward, as above stated, the guides are moved outward or away from the needles and then inward through the action of the levers 1 and t, the e1lt'eet of which movement of the guides is to bring the loops 011 the needles 1' well. forward under the beards of the needles, in order to 1revent the IlO thread from being trapped and broken by the action of the presser r on the beards of the needles.

By the above arrangement of parts the fabric is enabled to proceed directly upward from the sinkers and needles, thus enabling the workman to inspect and detect defects in the fabric immediately 011 production, which constitutes a most beneficial feature in knitting.

I would have it understood that I do not con- :fine myself to working and arranging the nee- (lles horizontally and to the relative position thereto of the other parts working in conjunction with the needles, as hereinbefore de scribed, as the needles may be set in any desired other position and the other parts relative thereto for various purposes.

Having now described my invention, what I claim is 1. The guide-bar I and brackets H for said bar, combined with the links 1: 10, supporting said brackets, lever a for moving said brackets, the lever L, for actuating said lever a and with the lever t and the camshaft, substantially as described.

2. The guide-bar I and its brackets 1-1, 00111- bined with the links a; w, levers 25, supporting said links a; w, shaft G, and the lever 11 for aetuatin g the levers 2, and with the lover a and the cam-shaft, substantially as described.

3. The guide-bar brackets 11', their supporting-links c 10, links 1 and rods (1 for the threads, combined with the levers t, that support the links 1: w, shaft G, and the lever y, for actuating the levers f, and with the lever a and the camshaft, substantially as described.

41. The combination of the guide-barbrackcts ll, links v a, supporting said brackets, levers t, carrying said links 17 w, shaft G, lever 1 for actuating the lGVOlS t, levers a and L, for moving the brackets H, and the cam-shaft, all arranged for operation substantially as herein shown and described.

The above specification signed by me this 8th day of December, 1887.
