This invention relates to machines in which yarn is spun or twisted. In the operation of such machines, "breakage frequently occurs in the spun or twisted thread, or in one of b the, strands from: whichthe thread is being formed, I
Itis' the generaliobjeot of my invention toprovideimproved means for stopping the rotation'of aspindle as soonas suchlbreakage occurs in the associated thread or inone of the strands entering into the formation thereof. Y A further object which the feed to the strands and the rotation of the Spindle are stopped substantially si -2o-clutch upon breakage of yarn or strand. I
also provide'for applying a braking pressure to 'the'spindle as the clutch is disengaged.-
My'invention'further relatesto arrangementsand combinations off'parts which will :2; be hereinafter described and more particularly pointed out in .the appended .Yclaims. A preferred form of the invention is shown in the drawings, in which 1 v v 'Fig. 1 is a sectional side elevation ofparts of a twisting machineyembodying my improvements; Fig. 2 isan enlarged sectional side elevation of my improved spindle and clutch mech: anism; 1 Figs.i3, 4 and 5 are sectional plan views, taken along the lines 3'3, H and 55 in Fig. 2 respectively; 1 'Fig. 6 is a'view similar to Fig. 2tbut showing the parts in a different position ,and 4 Fig. 7'is a sectional view, taken along the line 77 in Fig. 6. i
Referring to the drawings, I have indicated a portion of the frame 10 of a twisting machine, said frame supporting a. spindle rail-12 on which a' plurality of spindlesS is to provide means b'yare mounted 'in the usual manner.-- Strands ii of yarnY are drawn from'a creel (not shown) and pass under a guide-rod 14, through a guide-wire 15, over a roll 16, around apressure r0ll'17 andguide-rod 18, andjover an additionalroll l9to a traveler 20. on aring 22 mounted on aring-rail 24 which is recip rocated vertically bysuitable lifting mechamsm, not shown. i j ;.The pressure roll 17 is provided with gudgeons or bearing portions 26 rotatable in open 7 bearings27 at theupper endof a supporting member 28. The member 28 is secured to the upper endjofa sliding rod 30guided verti- I cally in bearings 33 and 34:. 7
r A" weight W is supported on a belt136, passing overa guide pulley 37 and connectedfto a collar 38 clamped on the rod 30. The weight -W thus tends to lift the pressure roll 17 out of engagement with the constantly'rotated feed rolls16 and 19. i
- A latch 10 is pivoted at 4-1 on the supporting member 28 and engages the underside of a stop plate 42 whenever the latch 40 is moveddownward with the member 28. Such engagement retains the member 28 in loweredgposition, withjthe roll 17 in free en gagement with the feed- rolls 16 and 19.
-Yarn-controlled mechanism is provided for disengaging the latch 40 and permitting the weight W to raise the pressure roll 17. For this purpose, a slide is-mounted in 'guideways in a stand51 on the frame 10 and has a portion 52 project-ing upward adjacent a rotating shaft. 54 onwhich cams 55 are mounted. Drops 56- are 'slidably mounted in the portion:52 of'the slide50 and are each provided with a =hook shaped portion at their upper end adapted to engage one of the strands of'yarn Ybetween the guide rod 14 and the guide-wirel5. 7
Each ofthese drops 5,6 is provided with a laterally projecting portion 60 which will be engagedby the cam 55 when the yarn breaksand the drop descends to its lowerposition. Such engagement will cause the cam to push the slide 50 outward, so that a projecting portion 62 of the slide will engage the lower end of the latch and free it from the stop plate 42. lhe weight W is then free to raise the rod 8,0and member 28 and thus separate the roll 17 from the feed rolls 16 and 19. V
An additional stopping member 65 is mounted on a lever-66 pivoted at 67 on the stand 50 and having an inward extension 68 also supporting a sliding bar in the portion 52 of theslide 50. If the thread T breaks the member 65 swingsupward and the portion 68 thereof movesdownward, bringing the corresponding sliding member into position for engagement by the 0&11155 and disengaging the latch 40 as previously described. f 1 The details of construction of the stop motion as above described form in themselves no part of my present invention, which relates more particularly to the provision of a clutch device for disengaging and stopping the spindle as the roll 17 is lifted.
Each spindles is provided with a blade 70, rotatable in an inner sleeve or bolster 71 (Fig. 2) -A collar 72 is fixed to the blade 7 O and is provided with an upper flange 73 which supports the. spool or bobbin B on which the yarn is wound. A driving whirl 75 is mounted on an anti-friction bearing 76,
v which in turn is supportedonthe upper portion of the spindle base or casing 77 A clutch member 80 is axially slidable on the outside of the sleeve 72 and is provided with an annular groove 81 to receive pins 82 in a yoke 83 formed on an arm 84 adjustably secured to the vertically movable rod 30 previously described. I I
A friction or braking element 85 is secured to the upper side of the yoke 83 in position to engage the under face of the flange 78 as will be hereinafter described. I
Ihe upper part of the whirl 75 has a free bearing on a projecting portion 86 of'the clutch member 80. This projecting portion 86 is provided with spaced slots 87 (Fig. 5) to receive clutch rollers or balls 88.- The lower end portion of the sleeve 72 is pggvided with flat or cam faces (Fig. 5) providing clearance for the balls 88 when in the mid-position indicated in-Fig. 7.
When the parts are positioned as indicated in Fig. 5, the rollers 88 are clutched between the inner surface of theupper'part of the whirl 7 5 and the cam faces 90 of the sleeve 72,'thus providing a driving connection between the whirl 75 and the spindle blade 70, the connection being on the order of the well known I-Iorton clutch.
When the clutch member 80 is in the lowered position indicated in Fig. 2, the screw portions 93 and cam grooves 94 cause the member 80 and sleeve 72 to be positioned as indicated in Fig. 5, thus permitting the rollers to lock the whirl75 to the sleeve 72 and spindle 70.
When the clutch member 80 is raised't'o the position indicated in Fig. 6, the rollers 88 are moved to the mid-position indicated in Fig. 7 and the whirl 7 5w rotates freely relative to the blade 70.
Furthermore,"as the actuating arm 84'and the clutch member 80 moves upward, the friction member 85 engages the under face of the flange 7 3, as indicated in Fig. 6 and brin s the spindle.70 quickly to rest. A collar 9 on the'rod 30 limits upward movement of the rod 30, the spindle blade 70 and the spool B. I
A pedal 95' is-attached to the rod 80 by which theparts maybe con veniently-re-set after yarn breakage has been repaired. When the rod 30 is moved down-' ward and is latched in. running position, as indicated in. Fig. 1, the clutch members assume theposition indicated in Fig. 2, and the spindle blade 70 is continuously rotated. When the rod 30 is released by the stop motion and moves upward, the arm 84 moves to the position shown in Fig. 6,disconnecting the clutch and applying braking pressure to theflange 73.
I have thus provided simple and effective means for disconnecting and stopping a particular spindle whenever the yarn or-thread or 'any -strand thereof associated with said spindle is broken. J
While I have indicated certain details of construction of a ball bearing spindle in this application, no claim is made thereto,'as this spindle construction forms the subject matter of a separate application, Serial No. 404,478, filed by me Nov. 2, 1929.
Having thus described my invention and the lower end of the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than asset forth in the claim, but what I claim is I In a spinning or twisting machine, a spindle comprising a spindle blade, a driving whirl face portions and said internal cylindrical surface, a collar slidable' on said sleeve and having an end portion extending freely between said internal cylindrical portion of mounted for free rotation concentric there'- ing members positioned between said flat sursaid whirl and the flatted portion of said sleeve and slot-ted to receive said rolling members, said sleeve having angularly disposed slots and said collar having studs extending into saidslots, and 'means to move said collar longitudinally on said sleeve,
thereby causing relative angular movement between said collar and sleeve effective to release said rolling members from driving engagement With said Whirl and sleeve.
In testimony whereof I have hereunto aflixed my signature. V
FRED K. HENDRICKSON.
