Definitions
- the adjustable tensioning means is incorporated with the general type. of two-for-one twisters now in use.
- the adjustable tensioning assembly will be described inlconjunction with the type of two-for-one yarn twister a shownin Figure 1 of the drawing. n g;
- a housing centering and locking member 21- having fingers 23, 23 which fit into the slots 19, 19 to lock the housing 17 in centered position on the p1atform9 is also 'secured't'o the platform 9. It should be pointed out that the support can 15 for the yarn bobbin 13 is centered upon the platform 9 through contact of the inwardly extending top edge of the can with the periphery of the housing 17. v
- a bonnet 30 is supported by the housing 17 with the base portion of the bonnet lying within the housing interior to form a sliding fit with the housing wall.
- the bonnet 30 includes an aperture 32 '( Figure 2) extending vertically through the'bonnet.
- a primary tension button or weight 34 may be, if desired, loosely suppported by a suitable apertured disc 36 ( Figure 2) mounted within the aperture32 at the top portion thereof.
- a guide tube 38 is inserted within the aperture 32 to provide a smooth surface for the yarn as it travels therethrough. 'Itshould be pointed out, however, that the use of the tension button 34 may be eliminated, if desired, since a primary tension will be applied to the 'yarn anyway as it passes through the aperture 32 against the aperture wall.
- the yarn Y travels upwardly from the yarn package and downwardly through the aperture 32 being 'tensioned while it passes under the tension "button 34. From this point, the yarn travels downwardly through the interior of the housing 17 and through a passageway 40 which extends through the housing looking means 21 and the drive shaft 1 to open upon the periphery of the drive shaft 1 as shown in Figure 1. From the passageway 40, the yarn is laced through a slot 42 of the twisting disc 5 whereupon a balloon B is formed within the .yarnas it passes upwardly to a suitable collecting unit not shown.
- Opposing magnets 45, 45 mounted upon the underside of the yarn-package platform 9 and upon the top wall of the motor 3 serveto prevent the platform "9 from rotating with the drive shaft 1. As the yarn-twisting disc 5 rotates, it of course 81)- plies a twist to the-yarn passing through the slot 42 of the twist-applying disc.
- theposLSO. Secured. to and extending laterallyfrom. theposLSO. are a plurality of fixed vertically disposed and spacedapart yarn-guide fingers 60, 60 which carry eyelet guides 61 at their free extremities through which the yarn passes. These guide fingers 60, 60 extend toward the center of the housing from the post 50 so that the eyelets 61 of the.;fingers lie directly in alignment with the: guide tube 38 supported within the aperture 32 of the bonnet 30.
- Pivotally supported in and depending from the lower por: tion 52 of the bonnet 30, is a shaft 62.
- the shaft 62 is also pivotally supported at its opposite end in and at the center point of the anchor plate 58.
- yarn-guiding fingers 64, 64 Secured to and extending laterally from the shaft 62 in fixed manner are yarn-guiding fingers 64, 64 which also carry eyelet guides 61 at their free extremities through which the yarn travels.
- the fingers and eyelet guides of the pivotal shaft will cooperate in interdigitating fashion with the fingers and eyelets of the fixed post 50.
- the tension applied to..the. yarn passing through the eyelets of both the fixed fingers and the pivotal fingers in alternating manner will depend. upon the extent to which. the eyeletsv of the pivotal shaft are brought into or out of alignment with. the. eyelets of the fixed post 50 as will be described hereinafter.
- a pivot link or plate 66 is secured to pivotal shaft 62 at the upper end thereof to extend laterally therefrom across the interior of the housing 17.
- An arcuate slot 68 is cut through the link 66 to accommodate the tube guide 38 which extends below the plate whereby the plate may be moved back and'forth across the housing interior to rotate the pivotal shaft and the fingers64 extending therefrom.
- the adjusting ring 70 has a self-locking assembly generally indicated at 76 ( Figure 2) whereby once the pivotal shaft 62 is. adjusted to the desired position by rotation of. the ring 70, it will automatically be locked in that. position during operation.
- the self-locking assembly 76 consists of a vertically disposed recess 78tcut into the upper portion 54 of. the. bonnet 30.
- a tension spring 80 is loosely supported within the recess 78 and has secured thereto a small metal ball 82. preferably formed of a hard metal. The ball member 82 is thus urged against the upper face. of the ring 70 by the tension spring 80.
- Cut into the upper face of the ring 70 are a plurality of semicircular indents 87, 87. These indents 87, 87 are located in spaced-apart relationship and follow an arcuate path as defined by the path of the ball member along the face of the ring as the ring is rotated (see Figure 3). The path is of short duration.
- the ring 70 is rotated in a clockwise or counterclockwise direction depending upon whether or not increased or decreased tension is desired.
- a clockwise rotation of the ring 70 will pivot the shaft 62 and the fingers 64, 64 secured: thereto further out. of alignment with the fixed fingers 60, 6.0 to. increase the tension upon the yarn traveling throughthe eyelets, of the fingers. Decreased tension uponthe yarn. will be achieved through a counterclockwise rotation of the ring 70 and shaft 62.
- Figure 4 shows the position of the yarn-guide fingers 64 secured to thepivotal shaft 62 with respect to the fixed. yarn-guide fingers 60 after the fingers 64 have been moved out of alignment with the fingers 60.
- a yarn-twisting apparatus comprising a drive spindle, yarn-twisting means secured to and rotatable with the drive spindle, a non-rotatable support for a yarn package which support is floatingly mounted upon the drive spindle to lie above the yarn twist-applying means, a housing supported upon the yarn package support and adapted to lie'within theinterior of the yarn package, an apertured bonnet supported at the top of the housing through which aperture the yarn passes from the yarn package to the interior of the housing, a fixed post secured at one end to the bonnet, a fixed set of vertically disposed yarn-guide fingers extendinglaterally from the post, a pivotal shaft depending from the bonnet, a series of yarn-guide fingers extending laterally from the pivotal shaft, said fingers of the pivotal shaft being adapted to interdigitate with the yarn-guide fingers extending from the fixed post upon pivoting ofv the shaft, a yarn passageway extending through said yarn package support and the drive spindle to open through the drive spindle pe
- a yarn-twisting apparatus comprising self locking means for locking the rotatable ring in its adjusted position.
- Ayarn-twisting apparatus comprisingindicia on the rotatable ring and bonnet for indicating. the position of. the yarn-guide fingers supported onthe. pivotal shaft.
- a yarn-twisting apparatus according to claim 1 comprising a tension weight loosely supported Within the aperture of the bonnet for increasing the primary tension applied to the yarn.
