Patented Dec. 9, 1947 YARN CARRIER FOR KNITTING MACHINES Albert Friedmann, Reading, Pa., assignor to Karl Lieberknecht, Inc., Reading, Pa., a corporation of Pennsylvania Application February 13, 1947, Serial No. 728,326
Claims. (01. 66-126) This invention relates to yarn carriers for knitting machines, more particularly straight knitting machines of the Cotton type such as are commonly used in the production of fashioned position of minimum strain or friction there-' upon as it is drawn from its source of supply.
How the foregoing and other important advantages are realized in practice will appear from the following detailed description of the attached drawings, wherein Fig. 1 is a view showing my improved yarn carrier in front elevation.
Fig. 2 shows the carrier in side elevation as viewed from the right of Fig. 1.
Figs, 3 and 4 are fragmentary front views of the carrier in vertical section taken as indicated by the angled arrows III-III and IVIV in Fig. 1 and drawn to a larger scale.
Fig. 5 is a fragmentary view in front elevation of the lower or delivery end of the carrier likewise drawn to a larger scale.
Figs. 6 and 7 are cross sections taken as indicated respectively by the angled arrows VI-VI and VII-VII in Fig. 5.
Fig. 8 is a cross section taken as indicated by the angled arrows VIIIVIII in Fig. 1; and
Fig. 9 shows the tip or delivery end of the carrier in bottom plan.
Figs. 6, '7 and 8 are horizontal sections taken as indicated respectively by the arrows VlI-VI, VII--VII and VIIIVIII in Fig. 1.
Fig. 10 is a fragmentary view corresponding to Fig. 5 and showing a modification.
As herein illustrated, my improved yarn carrier is characterized by having a fiat downwardly tapering finger III which is pendent from, and.
integral with, a crosswise rectangular top portion II. From Fig. 2 it will be observed that the finger also decreases gradually in thickness from the region of its mergence into the top portion H to its tip. In order that the carrier may be readily and quickly connected to or removed the endwise reciprocating carrier bar of the knitting machine indicated in dash and dot lines and designated B in Figs. 1 and 2, its crosswise top;
. 2 portion I I is provided with notches I2 for passage of the shanks of headed securing screws S. The finger I 0 may be given an angular configuration as shown in Fig. 2 or it may be made substantially straight depending upon which carrier bar (whereof there are usually several one behind another) of the machine the carrier is to be used.
For guidance of the yarn indicated Y, the carrier is provided at its top with a receiving tube I3 which is comparatively large in diameter and bore, and at its lower end with a delivery tube M which is tapered and of which the diameter of the bore at the bottom is substantially equal to the gauge of the yarn. Except for being flared at its upper end to facilitate entry of the yarn, the receiving tube I3 is cylindric and set into a cross sectionally concave groove I5 in the front face of the finger along its central longitudinal axis. A staple I6 fashioned from wire with its extremities anchored in the attaching upper portion I I of the carrierserves as a friction means for holding the tube I3 in place. Near its lower end, the finger Ii] has a relatively large verticallyelongate round-ended opening I1, and immediately below the latter is a much smaller circular opening 20, the two being connected by a central slit I8. A narrower slit I But extends downward from the circular opening to the tip of the finger for reception of the delivery tube I4, with incidental formation of clamp jaws I9. The side edges of the slit I 811 are longitudinally grooved as at 22 for lodgment of the tube I 4 centrally of the thickness of the finger tip, with its upper end stopped against shoulders 2| formed by the top of circular opening 20. In order to confine the yarn Y which is to be guided to a direct and straight path in the interval between the tubes I3 and I I, the front face of the finger I0 is longitudinally grooved medially as at 23 at the region of the bend 24 and provided at the half-way point with an eye 25, which, like the upper tube securing element I6, is shown as having the form of a staple with its ends similarly anchored in said finger.
The carrier may be die stamped or otherwise fashioned from metal or any other suitably stiff material preferably with incidental rounding or bevelling of the side edges of the finger portion as indicated in the drawings by the line shading, and the lower portion of the slit I8 bored or drilled to provide the grooves 2i in it side edges. After the drilling, the jaw portions at tip of the finger are pinched so that the slit sides are made to ccrsform to the taper of the delivery tube I 4, wh reupon the tip is hardened by tempering and accidental displacement during operation of "the" carrier, When the tube Mhas become worn, it can however be removed by reversing; the. fore; going procedure, i. e., by forcing it out of the slit 18a from above, and replaced by a new one The receiving tube l3 at the topof' the carrier is applied simply by forcing it downwardthrough the eye of the staple 25 until the flare at its pper end encounters the top edge of the cross portion H of the; carrier. ne'r again, -reinoval is effected by a. reversed operation when renewals become necessary. Through u provision of the open notches I2 it will be; seen that the carrier can beadjusted up or downasmay be required or removed from the bar B without entailing cornplete. removal and possible loss of the securing screvvs S.v
In Fi g. 10, Ihave illustrated, a modification wherein the opening 20a is bro ached to provide straight transverse shouldersjlaior abutment of the upper, end of the delivery tube I la; This construction is advantageous in that it insures the provision of apositive stopfor the tube Ma and precludes any-cainming action betweenthe shoulders Zla and the tube top as said tube is inserted such as might cause undue spreading of the jawsl9a M V g Having thus described my invention; 1 claim: v 1., Ayarn carrier for straightknitting machines in the form of a iinge r iashioned from stifi flat material with arelatively wide vertically elongate media ly d spo ed op nin adi cent s owe v a smaller circular, opening; immediately below he el n ate penina. a l n itudinal sl tco necting the two openings, a narrower slit with By reason of its taper, t e.
4 longitudinally grooved side edges extending downward from the smaller opening to the tip of the finger, and a delivery tube for the thread clampingly engaged in the grooved slit with its top end stopped against shoulders formed by the top of the circular opening.
2. A yarn carrier according to claim 1, wherein; he'delivery' tube is-tapredifrom top to bottom; .arid*.w'herein the'gr'ooved portion of the smaller slit is correspondingly configured to insure retainment of the delivery tube.
3. A yarn garrier according to claim 1, in which the"finger*has"a'crosswise attaching portion at its upper end with downwardly-open clearance notches for thefshanks of headed securing screws engageddn a supporting carrier bar of the machine. m H
4L 'A'yarn carrier according to claim 1, wherein the fi nger has a receiving guide tube for the thread in a medial groove longitudinall of its top, andwherein said receiving guide tube i held in place by an embracing staple whereof the ends are anchored in the: finger. I I
5'. A yarn carrier bag according to claim 1, wherein the finger'isfprovided medially of its upper end with a receiving thread guide tube; and at a point intermediate said receiving guide tube and the delivery tube'with an auxiliary guide eye for'the'thread. V, V c we ALBERT FRIEDMANN.
