SLUB CATCHER.

Application filed April 15, 1926. Serial No. 102,190.

The invention relates to a slub catcher for winding machines.

The object of the present invention is to improve the construction of slub catchers more especially that shown and described in my 1925,

copending application filed April 28, Serial No. 26,475, now Patent No.

1,585,315, and to provide an exceedingly sensitive slub catcher of simple,

practical and inexpensive construction adapted to positively prevent slubs from passmg to the spool on which the yarn is being wound.

With these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying dra wings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction,

within the scope of the claims, sorted to without departing from may be rethe spirit or sacrificing any of the advantages of the invention.

In the drawings Figure l is a plan view of a slub catcher constructed in accordance with this invention.

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a side elevation partly in section the portion in section being taken substantially on the line 33 of Fig. Fig. 4 is a rear elevation of catcher.

In the accompanying drawing in 2. the slub which is illustrated the preferred embodiment of the invention, the slub catcher comprises in its construction a supporting bracket 1 provided at its lower portion with a clamp 2 for sectional mounting it in position and having a front yarn guide 3 and a tension device 4c.

The supporting bracket is provided in rear of the tension device with a smooth face or jaw 5 over which passes.

the yarn The jaw 5 which is fixed preferably consists of a horizontal laterally extending arm round in cross section and recessed at the front at 6 to receive the lower portion of a floating feeler finger 7 which is scribed in the aforesaid application.

The supporting bracket is provi ded with i to the slot.

a substantially vertical transversely disposed upwardly extending portion 8 having a substantially rectangular opening 9 in its lower portion and having its outer side or portion 10 locatedabove and spaced slight- Y ly from the fixed horizontal jaw 5. The

feeler finger is mounted on'a pivot 11 lowith a stop 1 L consisting of a pin and located beneath the weighted arm for limiting the downward swing thereof and for maintaining the feeler finger when unthreaded in convenient position adjacent. the said outer side 10 of the bracket to receive the yarn and enable the same to be readily threaded after a breaking thereof or after one batch of yarn has been exhausted. .The feeler finger is provided at its lower portion with a slot 15 to receive the yarn and the slotted portion of the feeler finger terminates at the outer side of the slot above the portion at the inner side of the slot to enable the yarn to be readily introduced in- The extended portion of the feeler finger at the inner side of the slot forms a guide for directing the yarn into the slot. The slot preferably terminates at its upper end in an eye or opening as shown. The feeler finger is detachably hung on the substantially hook-shaped pivot 11 and it is adapted to swing transversely of the bracket and also has a limited swinging movement longitudinally in the direction of the movement of the yarn and its lower yarn receiving portion in use slides or moves along a lower cutting edge 16 of a hinged upper plate or member 17 constituting a movable jaw and cooperating with the fixed jaw 5 to form a yarn gripper. The hinged jaw is mounted in the opening 10 of the bracket on a horizontal pivot 18' which extends across the opening 10 and which is mounted in suitably aligned perforations of the transverse portion of the bracket. The horizontal pivot 18 is preferably movable to enable the hinged jaw to be readily placed in and removed from the supporting bracket. The hinged jaw of the gripping device is approximately U-shaped in vertical section and extends upwardly and rearwardly and then down.- Wardly and forwardly, the lower side being extended beyond the upper side and. projecting through the opening in the bracket and the said cutting edge 16. The particular shape of the hinged jaw throws the center of gravity above and in rear of the horizontal pivot 18 so that the tendency of the hinged aw is to swing forwardly, the forward movement being limited by a stop 19 consisting of an integral lug projecting laterally at one side of the hinged jaw and engaging the outer side 10 of the transverseportion of the bracket at the rear face thereof. This maintains the cutting edge in a forward projecting position and also in spaced relation with the fixed jaw to provide a passage for the yarn.

The yarn passes through the slot of the feeler finger and through the yarn gripper, the feeler finger floating with the yarn and sliding on the cutting edge or" the hinged jaw and when a slub reaches the feeler finger it turns to a vertical position to pass through the slot of the feeler finger and is then instantly caused to twist and turn to a horizontal position by the cutting edge of the hinged jaw of the gripping device. This will either break the slubor cause the slub to swing the hinged jaw into engagement with thefixed jaw and break the thread. As the. feeler finger is in contact with the cutting edge of the hinged jaw and slides on the same in any transverse movement of the feeler. finger the hinged jaw causes the instant twisting of aslub and'produces a positive breaking of the same. The feeler finger is adapted to move backwardly with the hinged jaw of. the gripping device in the closing movement thereof and there will be no opportunity by reason of any spacing of the feeler finger from the cutting edge of the movable jaw passing through the slub catcher without causing a breakage of the yarn. Slubs consist of soft untwisted portions of the yarn and will ordinarily pass through. an opening of a size sufficient to permit the passage of the yarn but it has been found that the flattening or" the slub to pass. through the slot of the feeler finger and the instant twisting of the slub at right angles will positively produce a breaking of the slub or an operation of the yarn gripper and a consequent breaking of the yarn. The hook-shaped pivot of the feeler finger will enable feeler fingers to be readily removed from and placedon the supporting pivot so that a feelerfinger having a slot of the required sizeinaybe readily placed in fixed jaw and normally spaced slightly above the same to provide a passage for the yarn and adapted to swing downwardly into contact with the fixed jaw and a pivoted float; ing feeler finger having a yarn slot and slid able on the lower edge oi -the jaw whereby a slub will be twisted by the teeler-finger and the movable jaw and either broken by such twisting or gripped and broken; ing of the hinged jaw.
