DAVID B. KIIVIES, OF SPRING CITY, PENNSYLVANIA.
KNITTING-MACHINE.
To all'whom it may concern:
Be it-known that 1, DAVID B. KIMns, a citizen of the United States, residing in Spring'City, Pennsylvania, have invented certain Improvements in Knitting-Machines, of which the cation. 1
My invention relates to-the knitting of fabrics and consists of an improvement in machinery for knitting rib fabrics.
Heretofore in machines for knitting rib fabrics where the ribbed effect was produced by one series of similarly operated cylinder needles and one series of dial needles operable in conjunction with .the cylinder nee; dles, the cylinder needles owing to the feed of theyarn and their relation to the dial needles prevented the latter from respectively drawing a similar amount of yarn under equal tension. Consequently the ribbed effect was practically only visible on the outer face of the fabric where the wales were produced by the cylinder needles; the inner face having very little indication of a ribbed effect, or projecting wales, because, the dial loops being tight and formed under increased tension did not contain as much yarn as the cylinder-knitwales. Fabrics known as Swiss ribs have been produced on two and two dial and cylinder machines in which the ribbed effect is present on both faces of the fabric. However,
following is a specifia fabric knit on this class of machine does not present a compact or even surface owing to the fact that the needle wales are arranged in alternating groups of two wales each or other similar combination; needle widths having been omitted between each group both in the cylinder and dialportions. The chief object of my invention is to quickly and cheaply produce ribbed fabrics which are extremely elastic and which will have a decided rib effect on both surfaces.
Another object. of my invention is to prevent holes or other defects in thefabric.
Other objects and advantages will be described hereinafter, reference being bad to the accompanying drawings in which:
Figure 1 is a perspective view of my invention and showing a set of cylinder needles and earns of a circular machine devel-- oped in a Hat plane and constructed in accordance with the idea of my invention and a dial cam-wave and needles shown in their Specification of Letters Patent.

full lines and showing the relative position of the needles therein; Fig. 5 is a sectional view taken on the line 0-e F 1g. 2 showing the cam-carrying'elements in full lincs and showing the relative position of the needles therein; Fig. '6 is a sectional view taken on the line dd Fig. 2 showing the cam-carrying elements in full lines and showing the relative position of the needles therein; Fig. 7 is a'sectional view taken on the line e-e Fig. 2 showing the cam-carrying elements in full lines and showing the relative posi tion of the needles therein; and Fig. 8 is a detached perspective view of a cam-supporting postwhich I employ.
Referring to the drawings, 1 is the cam cylinder which may be moved by any well known means in the directionindicated by the arrow Fig. 1 and carries cams 2, 3, 4-, G and 7 for operating the cylinder needles 8. A cam supporting post 9 is mounted within the cylinder and rests upon one end of a compression spring 10, and is vertically adjusted by means of a'screw 11 which is tapped in the top of the cylinder 1. lhe post 9 is made in two sections 12 and 13 longitudinally adjustable with respect to lation to the earn 2 it is only necessary to loosen the screws 17 and slide the section 13 until the cam 3 is in the desired position then to tightenthe screws 1'? and thereby clamp the section 13 to the section 12. y
The cam 2 has an extension 2* which anderlaps the cam l. This extension is slotted at 19, and screws.20 in the cam 4 extend through the slots 19 and engage a double tapped clamping nut 21. By this construction the cam 4 can be adjusted independ-.
ently of the movement of the cam 2 or it can be moved therewith. In order to have the cams movable on aplain outer surface of the cam cylinder 1, the latter is cut away at 22 to accommodate the clamp nut 21. A
' -In the drawings I have shown the dial cam 24 made .inone piece but it will be understood that this cam may be. Split up into sections, if desired, for purposes of adjustment in a manner simila-rto many dial cams now on the market. Also I have shown the described hereinafter.
Considering the action. of the cylinder cams: The cams 6 and 7 act upon the butts of the cylinder needles 8 in the usual manner, that is to say, the upwardly extending incline 25 on the cam 7 tends 'to raise the said cylinder needles to a point sufiiciently high to allow'the previously formed loops of the knitted'fabric to occupy aposition back'of the opened latches, and also sutiicientl'yhigh enough to receive a new supply of yarn (see Figs. 1, 2 'and 3); the cam-6 acting as a guide cam in the 'usual manner of knitting. The cam 2has a downwardly projecting incline 26'which next acts to draw the cylinder needles downwardly a distance sufiicient to cast their preyiously formed loops and together with an incline surface 27 forms a depending angle a: on the said cam 2 (see Figs. 1, 2 and 4). The cam 3 has a declined edge 28 and 'an inclined edge 29. These two edges 28 and'29 intersect to form a substantially V-shaped portion in the said cam 3 which is directly below the said depending angle w of the cam 2 The inclined portion 29 next acts on the butts of'the cylinder needles to again raise them but not high enough to place their loops back of the latches (see Figs. 1, 2 and 5). The cam 4- has a downwardly projecting inclined edge 30 which next draws the needles downwardly again. The came also has an inclined edge 31 whichv intersects with the said edge 30 to form ai'de'p'ending angle 32.. The cam 3 also with the inclined edge 29 to form an upwardly pro ecting angle or needle-raising point Y, and this inclined edge 33 is in alinel The cam 5 also has an inclined edge 35 which intersects with the inclined edge 34: to form a substantially Vshaped portion 36 which is directly below the depending angular portion 32 of the cam at. The edge 35 next acts to slightly raise the said cylinder needles again at which position they remain until again acted upon by the portion 25 of the cam 7. As before stated, the inclined edge 29 will not elevate the cylinder needles as high as does the inclined portion 25 of the Cam 7, this feature forms a very important function in my invention when cbnsidered with the action of the dial cam 24 as described hereinafter.
The dial cam 24 has an inclined portion 37 which acts on the butts of the dial needles 43, at the same time that the portion 25 of the cam 7 acts on the bntts of the cylinder needles 8, to project the dial needles into intermeshing position with the said cylinder needles in the usual manner as shown at A, Figs. 1 and 3, to placethe previohsly formed dial loops back of the full opened latches. In Fig. 1 of the drawings the yarn and fabric have been omitted for sake of clearness but the latches are shown in their operablepositions. An inclined surface 38 of the dial cam next acts to slightly retract the dial needles while the portion 26 of the-cam 2 is lowering the cylinder needles to grasp the new feed of yarn and to cast the previously formed loops. However, the portion 38 of the dial cam does not retract the dial needles to a point suliicientl farenongh to cast their previously former loops, but far enough to properly receive the new feed of yarn when fed thereto by the said downward movement of the cylinder needles and until they are aiiected by a portion of the cam 39 which substantially acts as a dwell for the dial needles and it is while the dial needles are under the control of the cam portion 39 that the cylinder needles are moved downwardly by the edge 26 to the lowest portion a; of the cam and cast their previously formed loops. After the cylinder needles cast their loops another inclined portion 10 on the dial cam acts to gradually retract the dial needles to grasp and pull the new feed of yarn into loops at the same time as the inclined portion 29 of the cam 23 again raises the cylinder needles into intermesh with the said dial needles to decrease the tension on the yarn while the dial needles are coinpleling the pulling of their loops. As the inclined portion 40 of the dial cam is of greater length and duration than the portion 29, the dial needles Will be retracting while the cylinder needles are has an inclined angle 33 which intersects being projected by the said portion 25), (as just stated and as shown in Fig. 5), and also while the portion 30 of the rain 4 is retracting' the cylinder needles as shown in Fig. (3.
6 5 ment Withan inclined .edge 34 on the cam 5. l hen the point portion 2 of the dial cam acts upon the butts or the dial needles the their loops substantially at this point; said casting being aided by the cylinder needles which are also being retract-ed at this time adjacent the portion The operation of the needles from this point until the timethat they are again affected by the portions .before mentioned is similar to the operation in any well known machines, that is to say that the dialand cylinder needles are slightly projected from their innermost position byfbeing acted upon by the portions 41 of the dial cam and the inclined edge 35 of respective dial and cylinder cams.
By having the cylinder needles cast their stitches previously to the time when the dial needles cast their stitches and by again raising the cylinder needles, after they have cast their stitches, into intermesh with the dial needles, the dial needles have a free chance to draw sufficient yarn to form loops which would not be'the case if the cylinder needles were pulling or drawing down upon the loops when the dial needles are pulling their loops. By this arrangement the dial needles have an. equal chance to draw as much yarn and under substantially the same conditions as do the cylinder needles. Also, as both the dial. and cylinder needles retract together, after the latter have been raised by the portion 29, to retract their respective needles, the loops will tend to be evened up before and up to the time of the dial needles casting their loops. In other words, the applicant is able to produce a ribbed fabric on' the machine: first, by casting the cylinder loops previously to the time at which the dial loops are cast during each course of the fabric; secondly, by again raising the cylinder needles while the dial needles are partially projected and sufiiciently far to re lease the tension on the cylinder needle loops and then drawing loops of yarn by the dial needles while the cylinder needles are thus partially raised, then by retracting both the dial and cylinder needles to effect an equalizing of the amount of yarn taken by each dial and cylinder needle.
In constructing the cams I preferably.
make the depending angle a: of the cam 2 with a flat surface, which is suliiclently long to accommodate the width of. two of the butts of the cylinder needles although the same can be made rounded if so desired; also instead. of having the edges 28 and 29 meeting in an abrupt angle, I preferably slightly fillet or roundthe same so as to allow a free passage of the'cams past the needles. Additional advantages are also obtained by having the upwardly projecting inclined portion 29 following the downwardly projecting inclined portion 26 of the cam 2; first, the release of the tension on the cylinder needles permit any imperfection such as double yarn or knotted yarn to draw 'through the needles without severing the yarn; second, in cases where knots of such a size as not to be able to pass through the nee-- dles will adjust themselves, owing to the fact that the yarn is sufficiently slack at this point third, it prevents the cylinder needles from loosing their loops in cases where they'are tucking as the cylinder needles are sutliciently high to prevent the loops from being slipped oft their ends; fourth, it renders the machine serviceable of knitting close, medium and loose fabric without altering the individual cam adjustment; it only being necessary to raise or lower the head which supports the dial. Also, it renders the machine capable of lmitting'yarns of different thicknesses-without alterin the individual cam adjustment, as yarns 0 an thickness may be usedsimply by slightly raising or lowering the head of the machine. Any slight adjustment-of the cams 2, 3 and 4 can be made to suit particular classes of goods being produced in a manner heretofore described. .The entire nest of cams 2, 3 and 4 may be lowered by screwing down on the screw 11 or if it is desired to raise the said cams it is only necessary to loosen the screw" 11 as the compression spring 10 will raise the same by acting on the bottom of the cam-supporting post section 12.
lVhile I have shown the principle of my Invention as. controlled by cams of specific formation and relation to one another, it will be understood that other means may be employed to obtain the. same result and yes without departing from the spirit of my in vention, as my invention consists principally of the ideas as heretofore disclosed of casting the cylinder loops previously to the cast ing of the dial loops and by again raising the cylinder needles to intermesh with the dial needles to release the tension on the yarn before the said dial needles draw the newly fed yarn to their innermost position and to cast the previously formed loops.
Also, to retract the cylinder needles and the dial needles simultaneously until the latter a cast their stitches.
My invention may be applied to single or multiple feed machines using one or more banks of cams, and it can be used with equal advantage in a one feed circular machine or where the fabric is produced entirely from the succession of courses made from the same feed. My-invention may also be applied to other machines in which the two so 'ries of needles are disposed substantially at right angles to each other or at angles other than 90.
