BUILDER-MOTION FOR SPINNING OR WINDING MACHINES.

Specification of Letters Patent.

Patented Feb. 8, 1921.

Application filed March 4, 1920. Serial No. 363,229.

T 0 all whom it may concern:

Be it known that I, ALONZO E. RHoAnEs, a citizen of the United States, residing at Hopedale, in the county of \Vorcester and State of Massachusetts, have invented an Improvement in Builder-Motions for Spinning or Winding Machines, of which the following description, in connection with the accompanying drawings. is a specification. like characters on the drawings representing like parts.

The invention to be hereinafter described relates to yarn spinning or winding machines, and more particularly to the means whereby a bunch may be produced upon the bobbin or bobbins during the spinning or winding operation.

In laying or winding the yarn upon bobbins for subsequent use in the loom, it is sometimes desirable to provide a few preliminary windings on the bobbins before commencing the regular or service wind. These preliminary windings are generally known in the art as a bunch, and this bunch may be provided to operate a feeler, or it may be provided to give the lower end of the wound bobbin the desired configuration.

The bunch should be laid by a different traverse of the yarn from that of the regular or service wind, and upon completion of the bunch it is desirable that the regular or service wind shall be automatically resumed. It is also important that the traverse for the bunch be made effective when the spinning or winding operation is started; and with these generally stated facts in view, an important feature of the present invention consists in providing mechanism for imparting a traversing movement to the ringrail in such a manner that a bunch of the desired configuration will be formed, after which the ring-rail will be automatically traversed in a manner causing the yarn to be laid upon the bobbin spindle in accordance with the desired regular traverse.

Another important object of the present invention is to provide novel mechanism for building the bunch upon the bobbin in such a manner that this bunch will extend along the bobbin spindle a less distance than the bunches heretofore commonly produced, whereby a relatively small amount of yarn is consumed in forming the bunch in the present device.

Another object of the invention is to provide novel means for rendering a bunch building mechanism inoperative upon completion of the bunch.

A further object of the present invention consists in providing means to coiiperate with the builder arm to thereby relieve the pivot upon which this arm is mounted. from lateral strains. And still another object of the invention is to provide means whereby the gears for operating the let-0H mechanism upon the builder arm may be readily moved out of operative engagement with each other.

Other features of the invention, in addition to the above, will be hereinafter described in connection with the accompanying drawing showing a good. practical form thereof. it being understood that details may be varied within the true scope of the invention as definitely set forth by the claims.

The invention is herein illustrated as employed in connection with a ring-spinning machine, and while it is particularly well adapted to this type of machine. it is to be understood that it may be employed with advantage in other types of spinning or winding machines.

In the drawings Figure 1 is a perspective view of a portion of a spinning frame showing the invention applied thereto;

Fig. 2 is an enlarged side view of the builder arm and mechanism mounted thereupon;

Figs. 3 and 4 are side and plan views respectively, of the gear positioning mechanism carried by the builder arm;

Fig. 5 is a plan view of a detail of the invention;

Fig. 6 is a side view of a bobbin spindle, showing in section the position of the yarn wound thereupon.

The machine frame for supporting the operating parts may be of any usual construction. and as typified in the present illustrated form of the invention, is of the usual type of ring-rail spinning frame, and comprises the end frames 10 connected by the longitudinal rail 11. This spinning frame may be provided with the spindle rail 12 upon which a plurality of spindles ma be mounts ed, one of which is indicated 13; and above this spindle rail is mounted the ringrail 1-1 carrying any preferred number of rings, one of which is indicated at 15. The

spindle 13 is shown as provided with a whirl 16 which is adapted to be driven by a belt 17 passing around the drum 18. In order that the ring-rail may be traversed to thereby properly position the yarn upon the bobbin it is raised and lowered by lifter 24. All of the mechanism so far described is old and well known in the art, and operates in a well known manner.

Pivotally mounted upon a rigid portion of the spinning frame as at 24 is the builder arm 25, having a rearwardly-projecting arm 26 carrying a weight 27 upon the rear end thereof. In order to impart the desired rocking movement to the builder arm, an operating cam 28 is provided having any suitable configuration, the particular cam shown being provided with four symmetrically formed faces. This cam is rigidly secured to a shaft 29 which may be 7 driven by any suitable means, not shown, and the faces of said earn are positioned to operatively engage a follower 30 carried by the builder arm, the construction being such that the follower 30 is normally held in en gagement with one of the faces of the cam 28 by the counterbalancing weight 27. R0- tatably mounted upon the builder arm adjacent the forward end of the same, is the drum 31, upon the stub shaft 32. This drum is rigidly secured to a gear 33 which may be driven by a worm wheel 34 mounted on the pick shaft 35, and upon the end of this shaft is preferably rigidly secured a ratchet wheel 36 positioned to be operated by the actuating pawl 37, connected to a portion of the spinning frame by a rod 38, the construction being such that as the builder arm moves in one direction, the pawl 37, which is supported in a predetermined position by the rod 38, will impart the desired amount of rotation to the ratchet wheel 36. The nadrant 23 is operatively connected to the rum 31 by a flexible member or chain 39, one end of which passes partway around the drum 31 and may be secured thereto by a screw or the like 40. The flexible member 39 preferably extends from the drum 31 and passes about a pulley or the like 41 rotatably mounted upon a fixed portion of the spinning frame, and from this pulley it extends laterally with respect to the builder arm to a bolt or the like 42 carried by the quadrant 1 23. The flexible member 39 serves to impart the regularor service wind to the ring-rail.

Upon the builder arm at a point nearer the pivot 24 'than the drum 31 is provided a shaft 43, upon which is rotatably mounted an arm 44, the outer end of which is operatively connected to the bolt 42 by aflexible member or chain 45. This arm 44 has a mutilated gear 46 rigidly secured thereto, the same'being rotatably mounted on the stub shaft 43, and the teeth 47 of this gear are positioned to be operatively engaged by a worm wheel 48 secured to a shaft 49 upon the outer end of which is mounted an operating pinion 50 which is driven by a gear 51 rigidly secured to the pick shaft 35. The builder arm 25 is preferably provided with an upwardly-projecting bracket. 52 upon the outer end of which is rotatably mounted a pulley wheel 53 over which the flexible member 45 passes.

The arrangement of the mechanism so far described is such that when the parts have been properly adjusted to start the winding of the bunch, the traversing of the ringrail will be controlled by the flexible member 45, while the flexible member 39, which controls the regular traverse, will be slacked off slightly, as shown in Fig. 1. When the spinning machine is started up, the builder arm will rock up and down in the usual man ner, due to the rotating cam 28; and as this arm reciprocates, the ratchet wheel 36 will be rotated and will effect rotation of the drum 31 by the gear 33 and cooperating worm 34. At the same time, movement will be imparted to the arm 44 through the

gears

51 and 50 and worm 48. Since during the winding of the bunch the traversing mechanism is under the control of the flexible member 45, the slow unwinding of the drum 31 in the direction indicated by the arrow will have no influence on the traverse of the ring-rail; but while the bunch is being formed, the outer end of the arm 44 is gradually being swung in an upward direction by the mechanism described, and this upward movement continues until the teeth 47 of the mutilated gear have been moved out of mesh with the worm 48, whereupon further rotation of this worm will no longer swing the arm 44 about its pivot. As soon as the teeth 47 have become disengaged from the worm 48, in the manner just pointed out, the arm 44 will be no longer held in a position to exert an operating pull upon the flexible member45, so that the bunch traversing mechanism will in this manner become inoperative upon the completion of the bunch, whereupon the usual service traverse Will be imparted to the ring-rail by the flexible 'member 39 and mechanism con nected therewith, it being understood that, during this service wind, the drum 31 is slowly unwound to permit the upward movement of the ring-rail to be gradually increased.

An important feature of the bunch-forming mechanism just described is the arrangement whereby the outer end of the arm 44 is adually swung upward throughout the evelopment of the bunch. This arrangement of parts causes each upward movement of the ring-rail in the production of the bunch, to rise a little higher than the preceding upward traverse, and to move downward] a distance not quite as far as the preceding traverse, whereby the yarn wound upon the bobbin in the production of the bunch will be deposited upon the bobbin in the manner indicated at 54, Fig. 6. In this fi re, it will be noted that the yarn is place upon the bobbin in successive layers of substantially the same length of traverse, and that each layer occupies a position slightly nearer the tip of the bobbin than the preceding layers. This particular manner of winding the yarn forming the bunch is desirable, because it produces a bunch which extends lengthwise of the bobbin a relatively short distance, and while providing the requisite initial supply of yarn produces the desired form at the base of the wound bobbin.

Due to the fact that the builder arm 25 is provided with an upwardly projecting bracket 52 carrying a pulley wheel over which the flexible member 45 passes, a considerable strain will be exerted upon the pivot 24 of the builder arm unless means is provided to relieve this strain. There is therefore provided an upwardly-projecting arm 55, the lower end of which is rigidly secured to a suitable portion of the spinning frame, and the upper end of the bracket 52 is provided with an anti-friction roller 56 positioned to rest against the said arm 55 throughout the reciprocation of the builder arm.

In order that the parts may be readily restored to the position which they should occupy at the beginning of the winding operation, means is provided by which the outer end of the shaft 49 may be manually swung away from the pick shaft 35; and in the embodiment of the invention shown, an eccentric member 57 is provided about the shaft 49, which member is rotatably mounted in the outer end of the builder arm 25. The eccentric member 57 is provided with a projecting arm 58 having a laterally-extending lug positioned to rest upon the finger 59 formed integral with the builder arm 25 while the gears are in mesh with each other. This eccentric member permits the gears to be readily moved out of mesh with each other by swinging the arm 58 upwardly, as shown in Fig. 3. whereupon a wrench or the like may be inserted in the square socket formed in the outer end of the

shafts

35 and 49, to rotate these shafts and thus restore the members operated thereby to the desired position. After the arm 4-4 has been swung upwardly to the position shown in Fig. 2,

in which the worm 48 is out of mesh with the teeth 47, it is desirable to provide means for retaining the parts in the position shown in this figure, so that as soon as the worm 48 is rotated manually in a direction to swing the arm 44 downward, the teeth 47 will be immediately engaged by the worm; and for this purpose the coiled spring 59 is coiled about the stub shaft 43, and has one end rigidly connected to the builder arm while the other end reacts against the mutilated gear, to normally hold the same in the desired position.

From the foregoing description read in connection with the accompanying drawings, it will be seen that a very simple but effective mechanism is provided for building a bunch in the manner above pointed out, and that after this bunch is completed, the bunch building mechanism automatically goes out of operation, whereupon the yarn is wound upon the bobbin spindle in a desired manner to provide the regular or service wind.

It will be apparent that various changes may be made in the device herein described, without departing from the scope of the invention, as defined by the annexed claims.
