20 Claims. (Cl. 2 12-35-6) This invention relates to an improvement in winders of the general type exemplified by the Colman Patent No. 1,267,977, dated May 28, 1918. The mechanism disclosed in that patent comprises a mechanically actuated grid for maintaining the yarn in proper relation to the cheese and for taking up slack in said yarn. It is impracticable to construct and operate such a device so as to handle the yarn with the requisite certainty without danger of placing excessive tension upon the yarn, and, as a consequence, yarn breakage has sometimes resulted.

The present invention aims to prevent 'such breakage, and this aim has been attained by the substitution of means employing an air current in place of the mechanically actuated grid. The improved means has not only remedied the difficulties heretofore experienced, but has made possible a substantial increase in the speed of 20 operation of the machine with a consequent increase in production.

Another object of the invention is to provide means for disengaging the yarn from the knotter.

I have herein shown my invention as embodied in a machine of the general type shown in the beforementioned Colman Patent No. 1,267,977

illustrated or described. It will be understood,

however, that the present invention is notlimited to machines of this specific character.

The winder may be considered as comprising a plurality of units, each unit having means for supporting a bobbin a (Fig. 11) and a crosswound yarn-mass or cheese 0, the cheese being revolved by a drum l, and the yarn being traversed by a cam groove 2 in the drum. The winder further comprises a mechanism arranged to travel along the winding units and tie the ends of the yarn on the bobbins to the ends of the yarn on the cheeses, and perform various other operations attending the production of cheeses. The winder-tending mechanism travels around the winder and ties the end of the yarn 11 (Figs. 3 and 11) on a reserve bobbin to every vcheese, except in the case of cheeses that have reached the desired size. As the winder-tending mechanism progresses, it places each thrownout cheese in sucession upon an end-finding device forming a part of the winder-tending mech anism. Said device comprises a roll 278 on which the cheese rests and whereby the cheese is revolved in the direction to unwind yarn from roll 218, the free end of the yarn on the cheese is drawn into the mouth 290.

Before the roll 218 has passed completely out from under the cheese, another roll 3! passes under the cheese, the rolls 218 and 3M revolving in the same direction and their upper sides being in the same horizontal plane.

The knot-tying mechanism 302 (Fig. 3) may be of any desired character, but preferably is of the weavers knotter type disclosed in the Peterson Patent No. 1,657,407, dated Jan, 24, 1928, and shown in Fig. 11 herein. Using the same reference numerals as, are employed in the Peterson patent in describing the knotter, and 8 are the lower and upper clamps, respectively, for the reserve thread d; 63 is a hooked member forming part of a device for clamping and severing the cheese thread; and ll, 12 and I1 constitute another clamp for the cheese thread, the part 11 being in the form of a hook to receive said thread.

The means for carrying to the hooks 63 and 11- of the knot-tying mechanism the thread that has been picked up by the suction tube 29] comprises an arm 3| 6 fixed to one end of a rock shaft 3H. on the free end of the arm 316 is a hook 325 (Figs. '7 and 11) to engage the portion of the thread extending from the suction opening 296 to the cheese. As the arm 3| 6 swings downwardly, it carries a bight of the thread to the knot-tying mechanism, slack being furnished by the unwinding of the cheese due to the rota tion of the roll 36!. If desired, the peripheral speed of said roll may differ from that of the roll 218, and it should be such that the cheese furnishes all of the thread for the loop or bight produced in the downward movement of the arm, 3l6, no thread being drawn from the suction tube 29L As the arm 316 swings downwardly,

the strand that extends between the suction tube,

4 (Fig. 7) which is fixed to the framework of the winder-tending mechanism. The suction current.

in the tube 29! keeps taut the strand extending from the cheese to said tube so long assaid strand is not clamped at any point between the cheese and the tube.

As the' arm 3! 6 completes its downward movement, 'a slack take-up 'r'oll 39-i passes into position below the cheese, said roll revolving in the direction opposite to the'di'rection of"rotation of the rolls 213 and 38!. A guard plate'392 (Fig? 7) fixed in the'framework of the traveling mechanism extends in front of the rolls 3B! and 39!. The strand extending between the cheese and the hook 325 runs over the upper edge of said By that time the roll 39| has caused the cheese guard plate. After the strand has been drawn down'by the hook 325 said strand is clamped by the devices 53 and Ti and severed by said device 63," and tied to the thread of the reserve bobbin.

to reverse its direction of rotation for the purpose of taking up slack in the united threads. However, the roll'39l cannot arrest the'unwinding rotation of the'cheese at an invariable point in thecycle, hence it is necessary'to make other provision to take up slack in that portion ofthe strand which extends between the hook 325 and the cheese after said portion has been clamped in the clamps 63 and ll of the knottenin order' to'keep said portion substantially taut at"al1 times so that it shall be under control and $0 that the thread shall not have an opportunity to kink after it has been clamped as alfore'sai d. It is also necessary to keep said strand'in the ve'rtical plane ofthe cheese'as the windertend ing' mechanism progresses-. In the before-monk tioned Colman Patent No'.'1,267,9'77, themea'ns provided for "these purposes consisted of amechanically-actuated grid formed "of; a thread-j pu'sh'ing'plate (designated M5 in said Colman patent) and a pair of fingers (numbered M1 in said patent). I substitute for this mechanicallyactuated grid a suction tube 660, the mouth of which is indicated at 601. The tube 600 swings in a vertical plane in front of and close to the the front I of the machine.

rel ati'vely thin or shallow. Thus, it willbe seen that'when the yarn is drawn into said' tube in the i'o rrn of a loop X (Figs. 7 andll) the not has space to remain inthe form 'of, an op'nbi' distended loop and that by reason, hr the thinR-i ne'ss of the tubefthere is not 'spa'ce forsuch the plate 692 has a guard flange loop to revolve, hence the loop remains distended and is not permitted to twist or kink,

The suction tube 688 is fixed to a pivot portion 605 which is mounted for pivotal movement upon a horizontal axis in a bearing 696 carried by the winder-tending mechanism. The tube 600 is swung in timed relation to the parts with which it cooperates by means herein shown as comprising a cam 60'! which is engaged by a roller 668 carried by a crank arm 699 that is rigid with the pivot 605. The cam 69? is fixed to a continuously rotated shaft 223 which is driven as shown in Fig. 38 of the Colman Patent No. 1,267,977.

In the pivot 605 is a duct 6| 0 (Fig. 10) which communicatesin all positions of the pivot with a duct GH in the bearing 686. The latter duct is Connected to a tube 6l2 which extends to a valve casing 6E3 (Fig. 5). In the casing 6&3 is a duct 6| 4 (Fig. 7) that serves to connect the tube 6|2 with an exhaust tube {M5, and a duct BIB that connects the tube 6l2'with a tube Gil which extends to a tube 6l'l (Fig. 12). The latter tube extends to a chamber (el'l which is connected to theoutlet 6i 1 of a blower Bll mounted on the traveling winder-tending mechanism. The inlet side of the blower is connected to the outlet of a separator chamber Bil The inlet of the separa tor is "connected to the suction tube 6 l 5.

Communication between the tube M2 and the tubes (H5 and 6H is controlled by means of a slide valve 618 having ports 618A and 6 {813 therein. The slide valve 6E8 is'reciprocated by means of a slide 6l9- attached to said valve, said slide having an elongated'opening 620 in which lies a circular portion of the shaft 223. The, slide 619 carries tworoller's 6'2l and'622 that respectively engage cams 623and 624 on the shaft 223.

In the following description of the operation, the term cycle is used to denote the series of operations that takes place for each winding unit of the winder, or, in other words, the series of operations that occurs while the winder-tending mechanism is travelling a distance equal to the distance between the vertical central planes of two successive cheeses c (Fig. 3). In each cycle, the shaft 223 makes one revolution, the downtake arm .SIB makes one up and down movement, and the tube 600 makes one to-and-fro movement; 1

Referring now to Fig. 3, which shows the down-take arm 3l6 asabout to catchthe yarnin its hook 325 and swing forward toward the reader-and down to the knotter: As the yarn is drawn down by the down-take arm 3|6,-- the strand that extends betweenthe hook'325 and the cheese is laid over the mouth 69L- as willbe understood from Figs. 3v and '7. Afterthe lower portion of the strand has been clamped in the clamps of the knot-tying mechanism," slack said strand is drawn into the tube 600. The suc! tion tube 600 then swings in the direction opposite to the direction. oftravel of the winder-tending mechanismfthe first portion of this.movement being relatively rapid so as to guide the yarn onto the center of the cheese. This movementtakes H place during the period between 7 andfl'l" in'the cycle. During the periodfrom 17 to178 (the united threads being released from the knotter at about or the end of the suction tube BDOcontinuesto move in the direction opposite tothe direction of travel of. the winder-tending mechanism, but at the same speed so as to remain stationary with reference to the cheese and close to the surface, of the. cheese. During-the period from 1'18? .to.23.8, the suction tube re slack-take-up tube 600 and the valve 616: The valve opens communication between the slack-- take-up tube 600 and the exhaust tube 6l5 while the slack-take-up tube is moving forward to receive a strand of yarn. The full suction continues while the mouth GUI is moving backwardly until about 110. The valve then partially closes. Between 180 and 220 (the mouthbeing then'stationary in its rear position) the air current changes from suction to an air blast, whereby air is supplied to the tube 600 to blow out the strand of yarn, if not already withdrawn by the roll 39L The air blast continues from 220 to 278 and then changes to suction, which continues from about 278 to 318.

A further feature of novelty in the present construction consists of means for disengaging the united threads from the knotter. The knottying mechanism shown in the Peterson Patent No. 1,657,407 includes a projecting portion against which the thread may hang after the formation of the knot. I-Ieretofore the movement of the thread toward the winding drum l, as the cheese is returned to the drum, has been depended upon to draw the thread away from this projection. However, the thread has occasionally failed to be. disengaged. I therefore provide an arm 6Z5 pivoted at 626 to swing in a horizontal plane. The rear edge 62'! is arranged to swing against the strand extending between the cheese and the knotter and push said strand rearwardly clear of the projection above referred to after said strand has been tied to the reserve thread.

The means for swinging the arm 625 in proper timed relation to the knotter comprises a, link 62%! extending between a projection 629 onthe arm B25 and an arm 630 fixed on the pivot or shaft 605.

It will be seen that I have substituted for the mechanically-actuated slack-take-up grid of the prior art a. suction tube which handles the yarn gently and yieldingly, but with the necessary certainty and definiteness. In addition, I have provided a new feature, that of disengaging the strand from the slack-take-up means after the knot has been tied. In the prior art, there was no means for throwing off the yarn from the slacktake-up. If the yarn failed to become free from the slack-take-up, the yarn would break. The end attached to the cheese would be wound up on the cheese, but the end attached tothe bobbin might be dragged along by the winder-tending mechanism and be carried into engagement with one or more of the threads of other units and eventually cause these threads to break down, or if the thread of such other unit did not break, the thread dragged along by the winder-tending mechanism might become engaged with such other thread and both be wound together on the cheese. The thread dragged along by the windertending mechanism might also cause the thread of another unit to leave the cam groove of the cheese-rotating drum and thus cause the thread to be wound circularly around the cheese instead of spirally.

The terms yarn and thread are used herein interchangeably and to denote any analogous material.
