9 Claims.
This invention pertains to yarn measuring or yarn controlling devices applicable to textile machines and more particularly to knitting machines having a plurality of feeding stations at each of which one or more threads or yarns is or are knitted into the fabric. The improvements constituting this invention are, for illustrative purposes, shown as applied to the yarn furnishing or measuring mechanism shown in the patent to Howie 1,562,829, November 24, 1925, and some of the parts shown in the drawings of the present application are duplicates of the parts shown in the said Howie patent.
In the drawings:
Fig. 1 is a fragmentary plan view showing three adjacent feeding stations each of which is equipped with the present improvements for effecting the knitting of uniform fabric;
Fig. 1a is a fragmentary View partly in section taken along the line iala, Fig. 1;
Fig. 2 is a fragmentary view in side elevation showing the yarn furnishing or controlling means associated with each feeding station;
Fig. 2a is a detail view taken along the line 2a2a, Fig. 2; and
Fig. 3 is a fragmentary view in front elevation of the parts shown in Fig. 2.
Mounted upon the frame 5 of the machine at 2, 3 and 4 are three yarn controlling mechanisms each of which is associated with a feeding station (not shown). As the yarn controlling mechanisms 2, 3 and t, etc. are identical, the following detailed description of one only of such yarn controlling means will be given.
At 5 and 6 are shown two conical, intermeshing yarn furnishing wheels by the rotating teeth of which a yarn l is drawn from its source of supply and led to the needles of a knitting machine (not shown) in a manner hereinafter to be more fully described. The wheel 5 is mounted on a shaft 8 and constantly rotated by gearing all as disclosed in the Howie Patent 1,562,829. The wheel 6 drives the wheel 5 through the intermeshing teeth of the two wheels, the wheel 5 being loosely mounted on a shaft or stud 9. The shaft or stud 9 and wheel 5 are mounted on one arm of a right-angled lever bracket iii which is pivoted intermediate its ends at H to an ear or lug l2 upstanding and integral with the frame 5 I. The other arm of the lever IE3 adjacent to its free end it engages under an over-hanging bracket arm M of the bracket RE which adjal cent to its other end passes through a v rtically disposed slot in the frame 1 terminating in an angularly disposed toe portion or lug i6. Adja- (Cl. 66l32) cent to the toe it a pin i'i passes through a longitudinally disposed slot E8 in the bracket Hi and into a recess in the frame 5. The pin adjacent to its inner end has an annular groove it within which seats the end of a terminal portion of a 5 screw 2% which prevents endwise movements of the pin i? but permits rotary movements thereof. The other end of the pin ll is slotted as at 2i to be engaged by a screw driver or other implement for the purpose of imparting turning move- 10 ments to the pin H. An eccentric 22 is fixedly mounted on the shank of the pin ll between the head thereof and the frame i and is in engagement with the toe or lug iii. As will be evident from an inspection of the drawings, turn- 15 ing movements imparted to the head 25 of pin Fig. 3, will cause the eccentric 22 to engage the toe or lug i6 and move the bracket l5 downwardly within the limits of the pin and slot connection ill-48 and against. the tension of a spring 23 which bears against the upper surface of the frame l and against the under surface of the end 23 of the lever i0. Turning of the eccentric 22 causes graduations 2'2 thereon to register with a line or nick 22 in the frame l, or in a plate attached to and forming part of the said frame. A few only of the graduations 22' are shown in Fig. 3 although it will be evident thatthere may be as many graduations or divisions as desired and permitted by the peripheral extent of the eccentric From the foregoing it is evident that fine adjustments of the intermeshing of the wheels 5 and 5 can be readily effected, thus making it possible so to adjust the respective pairs of wheels 5 and fiat each of a plurality of feeding stations as initially to cause the several pairs of feeding wheels 5, 6 to tend to feed the same amount of yarn to the needles at one feeding station as at another. To readjust the position of the gear 5 with respect to the gear 6: turning movements imparted to the shaft I? which cause the bracket 55 to be lowered move the arm it of the lever ii downwardly and against the tension of the spring and turning movements imparted to the shaft ii in the op- 45 pcsite direction permit the spring 23 to raise the arm 53 and maintain its upper face in contact with the bracket i i. Prior to readjusting just described, the position of the gear ii with respect to the gear 6, a set screw 2 is 0 turned to release engagement thereof with the bracket l5, and subsequently to the turning of the eccentric 22 the set screw 24- is again turned to retain the bracket !5 in the adjusted position desired. 55
Mounted upon the upper surface of the frame I is a bracket 25, an arm 26 of which extends out over and beyond the gears and 5 and has attached at its end an arcuate calibrated plate or scale 21. The bracket 25 may have a porcelain or other eyelet 28 through which the yarn 7 passes from the source of yarn supply to and between the gears 5 and 6. Mounted to turn freely on the bracket 25 as at 29 is a disc-like element 30 to which are attached arms 3|, 32. The arms 3|, 32 are adjustably fastened to the disc 3|] as at 33, 33. Arm 3| normally depends from the disc 3|] to such a position as to permit the yarn to pass through an eyelet 34 in the said arm 3| and from there between the yarn furnishing wheels 5, 6. The yarn 1 after leaving the wheels 5 and 6 passes through an eye 35 provided in a wire arm 36 attached to the frame From the eye 35 the yarn 1 passes upwardly and through an eyelet 31 carried by an arm 38 adjustably fastened as at 39 to the arm 32. After passing through the eyelet 31 the yarn I is led downwardly and to the needles (not shown) of the knitting machine.
The bracket 25 has a recess 40 therein within which a pin 4| is received, the said recess limiting the movements of the pin and consequently the swinging movements of the disc 30 to which pin 4| is attached, as indicated in Fig. 2. Attached to the pin 4| is a counter-balancing weight 42 which, when the yarn is not passing through the eyelet 31, causes the arm 3| to assume the dotted line position, Fig. 2.
The plate 27 is slotted as at 43 and through the slot the end of the arm 32 passes, said end being turned at right angles as shown at 44 thereby to indicate to the observer readings of the scale markings on the plate 21.
In utilizing the present invention, the wheels A, 5 and 6 at the several feeding stations are adjusted by turning eccentric 22 and moving bracket l5, as described, so that their respective teeth intermesh exactly to the same extent. Thereafter the several yarns 1 are threaded through their respective eyelets 28, 34, 35, 37 and engaged by the hooks of the needles and knitted into the fabric. Then at one feeding station the stitch knitting cams may be adjusted (either those acting on the needles or those acting on the sinkers) until the pointer 44 arrives at a predetermined position at which the needles are knitting the desired number of stitches per inch of fabric. This done the operator of the machine adjusts the stitch drawing cams at another feeding station until the corresponding pointer 44 gives the same reading as that shown at the first feeding station, the stitch drawing cams being adjusted at the remaining feeding stations in the same manner.
Ordinarily when, due to wearing of the stitch drawi g cams or other causes or when a finer or coarser fabric is to be knitted, necessary adjustments are efiected by changing the intermeshing of the teeth of the wheels 5 and 6 and/or changing the positions of the stitch drawing cams at the several feeding stations so as to knit uniform fabric. This frequently requires spotting the several yarns and noting the lengths of yarn thereafter knitted at the several feeding stations after which appropriate adjustments of the stitch drawing cams are made to effect uniform knit ting of the several yarns at the several feeding tati ns.-
The movements of the arm 32 along the: scale markings on the plate 21 cause corresponding movements of the disc 30 and arm'3l so that the thread is moved along the rolls 5 and 5 which taper toward theirouter ends and as a consequence thereof when the thread 1 is in the position shown in Fig. 2, more yarn is fed to the needles by the said rolls than when the arm 3| moves to the right. Movements of the arm 3| and the yarn 1 along the rolls 5 and s is brought about by adjusting the stitch drawing cams, e. g. when the stitch drawing cams are adjusted to draw shorter stitches than before the arms such as 3| move to the right, Fig. 2.
Obviously while the weight 42 serves as a convenient means for urging the disc 33 and arms 3|, 32 to the dotted line position, Fig. 2, other means such as a spring can be utilized.
Although in the foregoing description several parts have been described more or less specifically, it will be understood that it is not the intention to limit the invention otherwise than by the terms of the claims themselves.
