'KNITTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 632,327, dated September 5, 1899.

Application filed November 14, 1898. Serial No. 696,445. (N9 model.)

To all 1071,0111 it nuty concern.-

Be it known that I, GEORGE FREDERICK;

STURGESS, hosiers engineer, a subject of the Queen of England, residing at the Inglenook,

Leicester, in the county of Leicester, England,

This invention refers to knittin -machines particularly to those which have two needlebeds coacting.

This invention has for its object to dispense with the pivots, moving cam-plates, carriers, springs, elastic bands, and such like devices now employed to retain or hold webbers in the slideways of the comb of the needle-bed; also, to dispense with the dial-posts, lugs, retarders, and such like devices now employed to normally maintain the fixed relation of the fixed needle-beds; also, to dispense with the weights, rollers, and such like devices now employed to normally hold rib fabric in knitting position and to impart apiercing action to carry free staple to the back of the fabric, obtaining a self-retaining slidable webberde vice operable from the bed-face and a more elastic and smoother-faced fabric than heretofore.

Figure 1 is a sectional elevation view of coacting needle-beds of the cylindrical and radial type, out through on lines A and B of Fig. 2. Fig. 2 is a top view of the needle-beds shown in Fig. 1 with a portion of the radial bed cut away. Fig. 3 is a top view of the detachable part of the first needle-bed separated, showinghow it is pieced up; and Fig. 4 is a sectional view of the same through one of the attaching-screws. Fig. 5 is a front elevation view showinga part of the coacting needle-beds and the stitch-hook or webholder, looking at the right sides of Figs. 1 and 2, the detachable part of the cylindrical bed being omitted in order to show the webbencomb ways and recesses,the first bed being broken away at its upper edge in one part to clearly show the front edge of the second bed. Fig. 6 is a sectional elevation view of a part of the beds with the webbers and the detachable part of the cylindrical bed omitted, clearly showing the combway and recess. Fig. 7 is an under side View of a part of the radial needle-bed shown in Fig. 1, showing the comb. Fig. 8 is a side view, and Fig. 9 a top view, of a detached webber. Fig. 10 is a side view of a stronger form of webber for use in coarsegaged machines. another modification of webber and of the top part of a needle-bed in which the detachable part of the needle-bed is omitted. Fig. 12 is a side view of the webber shown in Fig. 11, disclosing the manner in which it is connected to its fixing-blade. Fig. 13 is asection view of the fixing-blade detached, cut through on lines 0 Dof Fig. 12. Fig. 14 is asectional elevation view showing a modified form of webber applied to a well-known combination of ooacting cylindrical and conical needlebeds. I Fig. 15 is a top view of a portion of the cylindrical needle-bed shown in Fig. 14, showing the webber-cam. Fig. 16 is a front View ofa portion of the cylindrical needle-bed shown in Fig. 14, showing the webber-cam. Fig. 17 is a sectional elevation of two coacting needle-beds, showing another form of the webber applied to a Well-known combination of flat needle-beds; and Fig. 18 is a plan view of a portion of the needle-beds. Fig. 19 is a sectional elevation, Fig. 20 is a front view, and Fig. 21 a top view, of a portion of an ordinary needle-bed, showing a further modification of webber constructed in accordance with this invention adapted to existing needle-beds.

Referring to Figs. 1, 2, 3, .4, 5, 6, 7, 8, 9, and 10, above the face 1 of the first needle-bed is the usual webber-comb 2; also, recesses 3 in the face of the bed, making a continuation of the combways 5, extending downwardly and inwardly from the front to the back of the needles 27at point 4. At the bottom of. each of Figull is a view showing 7 the combways 5 is provided a slideway-seating 6 and 7, extending up the face sideand down the back side 8 of the base of the bed, making a plurality of webber bearings. Seated in the grooved surface 39 isa detachable part, which is comprised of two

parts

40 and 41, pieced up in the groove 39 by attaching-

strips

42 and 43, screwed to the ends of the

parts

40 and 41 by

screws

44, 45,46, and 47. Grooves 49 for the passage of the needles and webber-comb ways 50 in line with the re,- cesses 3, the bottoms of which form the conveXedslideway-seatings 51, are provided in the detachable part. The complete bed forms.

in the webber-comb open-ended guideways, each of which has a plurality of slideway seatings or bearings, any two of which form sufficient length of bearing to detachably retain a coarse and durable webber.

The second bed 21 has a webber-comb 20, extending from the front to the rear of its needles 36, making broad Openings 23 for the passage of the knitted loops and narrow openings 24 in alinement with the combways of the first bed for the reception of the needlepointed webber-teeth and projecting teeth 22, which serve to hold the fabric up to the piercing action of the webber-teeth and by engagment with the sides of the webbers to hold the two beds locked in a fixed relative position.

The webber 9 (shown in Fig. 8) is provided with a plurality of needle-pointed teeth, comprised of a needle-pointed tooth 10, making a hook 11 for engagement with the newlyformed loops, and abreast 12, over which the thread-loops are drawn, and a needle-pointed hook 13 below the breast 12 for piercing the mesh or loops of the completely-formed fabric to carry free staple through from the face to the back of the fabric and depress the fabric. In order to knit fabric from rough and long staple yarn with a smooth face, extra needlepointed teeth are added below the breast 12, as seen in 'Fig. 8, one of which is bent aside to enter the needle-loops. (See 52, Fig. 9.) The webber is also provided with inwardlyprojecting shanks 14.- and 15 and

openings

17 and 18, making a clear (having no cam-foot projections) slide-seating, continued up one side and down the opposite side, forming a plurality of slide seating or bearing edges, which serve by engagement with the slideway seatings or

bearings

6, 7, and 51 to make the webber self-retaining in the combways.

The needle-beds and webbers shown are drawn in a very coarse gage in order to clearly illustrate the device; but in practice in such coarse-gaged and strong beds and webbers as those shown, in which there is also sufficient room for the rear shank 14 to be retained, the detachable part 40 and its seating 51 are omitted, as shown in Fig. 6, in which case the webber is made stronger by being shanked, as seen in Fig. 10, its front opening being omitted. Each webber is provided with a cam-recess 19.

In working position the webbers protrude from the combways to the face of the bed and are operated by an arch-cam 30, engaging the sides of the recesses 19, secured to a traveling part of the machine 25, comprised of parts and 26, joined by pivot 29 and spring-clasp 28, the part 26 of which may be opened for the handling of the needles 27 or webbers 9. An inner swell 33 and

outer swells

34 and 35 of the arch-cam 3O slide or reciprocate the webbers in the comb-guideways, the swell withdrawing the needle-pointed teeth from the fabric and from the comb of the second needle-bed, while the thread is drawn across the breasts 12, and new loops are formed and passed through between the connecting-beds, and the swell 34 or swell 35, according to the direction of knitting, slides the needlepointed teeth in the opposite direction into the comb of the second bed in a manner as to pierce all loops with which it may come into contact rather than trap or cut the loops upon the second bed, causing the teeth below the breasts to pierce the succeeding courses of loops, carrying loose or free staple through the completely-formed mesh and increasing the elasticity of the fabric by making the loops more round and slides the upper teeth into the comb of the second needle-bed, bridging over the intervening space and makinga complete connection with the two beds, except on that section where the swell 33 of the arch-cam withdraws the webber-points from the second combway to allow of the formation and passage of new loops between the needlebeds.

In machines of fine gage so much of the substance of the detachable part is cut away by the frequency of the adjoining needle-grooves and combways as to leave insufficient strength or room for the

attachingscrews

44, 45, 46, and 47, and consequently such a fine-gaged detachable convex slideway seating or hearing 51 if it could be made in this combined form would be useless. Therefore in such a fine machine the said slidewayseatings are detached from their ring-support, as it were, and made separately in the form of fixing-blades. Each fixing-blade is comprised of the counterpart of a webber inserted in a combway, and bears or carries the webber, making a compound or two-part webber 54 and 56, as seen in Fig. 11. The fixing part 53 is chopped or pressed from the movable toothed part 54 in the position shown in Fig. 12. The cross-bar 55 connects the strip 58 to the body 56 to allow the fixing part 53 to be swung around the shank of the toothed part 54 into the operative position, Fig. 11. The needle-bed has a groove 57, which admits the setaside part 55 to hold the blade 53, which is wedged in the combway, in position, while the toothed part 54 is reduced on its sides to allow of its sliding freely in the combway in the manner shown in Fig. 11. This compound webber can be detached when the shank 14 is not cut away even by sliding the toothed part backward until the shank 14 passes over the upper edge of the base 1 of the needle-bed, when the fixing part 53 and toothed part 54 can be forcibly withdrawn from the combway and afterward separated.

In applying the device to existing coarsegage machines in which the webbers may be made thick and strong enough to allow of it it is not necessary to construct a special needle-bed. I adapt the ordinary needle-bed, as seen in Figs. 19, 20, and 21.

dles having been replaced by needles having shanks of finer gage in their upper part, a

The coarse neecomb is out in the upper edge of the needlebed 77, the combways of which are in line with the needle-grooves 76, each combway being provided with a seating up the front and continued down the back or opposite side of the bed, making a plurality of

seatings

78 and 80 on the base of the bed 77. The webber 75 is inserted in the comb-slideway, the back shank 79 sliding on the seating SOand the front shank 74 sliding on the seating 78 in side a needle-groove 76 alongside a needle. Referring to Fig. 19, the arched webber-cam 71, engaging the recess of the webber, fixed on a traveling part of the machine similar to the arched webber-cam before referred to, slides the webber from the full-line position by first lifting and then pressing the webber horizontally to the dotted position while new loops are formed, then sliding it back again to fullline position by drawing it downward.

Referring to Figs. 14:, 15, and 16, the device is shown applied to the well-known inverted conical second bed. The slideway-seatings 59 and 60 in the recesses and combways on the base 1 of the bed, beneath the comb 2, and the seating edges of the webbers 61 are necessarily on straight parallel lines, the extremity of the rear shank being in this case pointed and serving the purpose of a fabric-piercing tooth. The comb 69, which extends downward at the back of the needle-tricks and needles 68 of the second bed, holds the fabric up to its piercing action as it enters the comb. The webbers are operated in a similar manner by an arched cam 64, engaging the recess in the webber and secured at the angle shown by

screws

66 and 67 to a traveling part of the machine, which in this case is faced up at 70 to the edge of the outer webber-shank, giving the webber further support.

Referring to Figs. 17 and 18, the invention is shown applied to the well-known parallelbed type of machine, the webber 7 3 being mounted and operated on the

beds

71 and 72 in a similar manner, as will be instantly understood by comparison without further reference.

I am aware that it is common for webbers (web-hooks, web-holders, stitch-hooks, and loopers) to be held up to a straight or curved seating.
