15 Claims.

This invention relates to spinning machines particularly of that type in which spindle rails carrying the spindles and yarn receivers or bobbins are moved vertically to traverse the spindles relatively to the fixed ring rails carrying the rings. Such a spinning frame is illustrated and described in the prior Patent No. 1,824,788, granted September 29, 1931. As pointed out in this patent, the weight of the spindle rails, the spindles thereon, the yarn receivers on the spindles, the yarn wound on the yarn receivers and the other parts of the mechanism movable with the spindle rails is very great. At the conclusion of the spinning operation, this entire weight must be raised to bring the parts into doffing position. The invention of the prior patent provided power driven mechanism which at the conclusion of the spinning operation could be connected to the spindle rail and which acted when thus connected to raise the spindle rail and its load by power to the doiiing position. But when thus raised to doffing position, the spindle rail and its load wasnever entirely out of control of, or free from movement by, the builder motion. And this enabled the operator to utilize the cam of the builder motion for relieving the weight of the spindle rail and its load from the mechanism employed for holding the parts in raised position and thus enable the spindle rail to be restored to full control by the builder motion.

But it is frequently desirable in winding the spun yarn upon the yarn receivers or bobbins first to form a small bunch before the winding of the yarn mass is begun and to have this bunch located at the base of the yarn receiver with the lower edge of the bunch at or below the lower edge of the subsequently wound yarn mass. Such a bunch is particularly desirable to enable the yarn unwound from successive yarn receivers to be tied together so as to form a continuous strand. For this purpose the end extending from the base of one yarn receiver is tied to the end extending to the tip of the next yarn receiver so that as the yarn is completely unwound from the first yarn receiver, there is no cessation or break in the unwinding operation as the'yarn immediately begins to unwind from the succeeding yarn receiver. This operation is very desirable in dressers, warpers and various machines. It isimportant, however, that the yarn forming the bunch may readily and freely be withdrawn to the extent necessary to enable it to be tied to the yarn of the next yarn receiver and for this 55. reason it is necessary to locate the bunch so that its lower edge is at least at the lower edge of, and preferably well below, the yarn mass. In fact, it may be desirable for the bunch to be located entirely below the yarn mass.

It will be seen, therefore, that to effect such a 5 location of the bunch it is necessary for the spindle rail to be held in its raised position during the formation of the bunch entirely out of control of the builder motion. Consequently the builder motion, and more particularly the builder l0 cam, cannot be utilized for relieving the weight or the pressure of the spindle rail and its load on the mechanism holding it in its raised position.

The object of the present invention is to provide simple and efiicient means in a spinning 15 frame of the type described which will enable a bunch to be wound on each yarn receiver with the lower edge of the bunch at or below the lower edge of the subsequently wound yarn mass The object of the present invention is further 20 to provide in such a spinning frame means for relieving the weight or pressure of the spindle rail and its load at the conclusion of the formation of the bunch from the means for holding it in raised position thus to enable the spindle rail 5.

to be restored to the control of the builder motion and the spinning operation to proceed.

The present invention has for its further object to prevent the operation of the means for raising the spindle rail and its load to the required predetermined raised position if the mechanism for holding the spindle rail raised is not in operative position.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

As the general construction and operation of a preferred form of spinning frame in which the invention may be embodied is well known and 0 familiar to those skilled in the art and is further disclosed in the aforesaid Patent No. 1,824,788, it is only necessary here to illustrate and describe so much of the spinning frame as is necessary to a disclosure of a preferred form of the present invention.

In the drawings:

Fig. l is a transverse sectional'view looking toward one of the end frames of a spinning frame 50 with many of the parts removed.

Fig. 2 is an enlarged detail in cross section taken on the line 2--2 of Fig. 1.

Fig. 3 is an enlarged detail of the pawl and ratchet mechanism and associated parts looking toward the left of Fig. l and showing the pawl in holding position.

Fig. 4 is a view similar to Fig. 3 with the pawl shown in released position.

Fig. 5 is a top plan view partially broken away of the construction shown in Fig. 3.

Fig. 6 is a side elevation partially broken away of a full wound bobbin with the bunch located with its lower edge at the lower edge of the yarn mass.

Fig. 7 is a View of a full Wound bobbin with the bunch located with its lower edge below the lower edge of the yarn mass and in this case with the entire bunch located below the yarn mass.

In the construction illustrated end frames are provided, portions of one of which and the whole of the other of which 2 constitute the major supporting members of the spinning frame. The yarn receivers or bibbons 3 are mounted upon spindles having the whirls 4 and the spindles are carried by spindle rails 5 situated respectively at the sides of the spinning frame. These spindle rails are connected together by a plurality of transverse connectors 5 and these connectors at their ends slide upon and are guided by vertically disposed fixed guide rods 1. The ring rails 8 carrying the rings 9 are fixedly mounted upon the upper ends of these guide rods 1.

The builder motion, as more fully described in the aforesaid Patent No. 1,824,788, comprises an arm I!) pivoted at H on the end frame I and provided with a follower l2 cooperating with the builder cam l3 journalled at 14 on the end frame I and driven in the usual manner from a moving part of the frame. A flexible connector in the form of a chain|5 extends around and is secured to the drum i6 journalled at l! on the arm l0 and forming a part of the pick motion for imparting gain to the traverse, all as illustrated in the aforesaid patent. This connector i5 extends around and is secured to a sprocket wheel |8 rigidly mounted on a shaft l9 extending transversely of the frame and journalled at its ends in brackets 23 and 2| secured to the longitudinal girders 22 and the end frame I.

The entire unit comprising the spindle rails, spindles, yarn receivers, transverse connectors 6 and parts carried thereby is supported by a plurality of flexible connectors 23 secured at their lower ends to the transverse connectors 6 extending upward around suitable idlers, two of which are shown at 24, and thence down around and connected to ratchet wheels or drums 25 secured to the shaft Hi. It will thus be seen, as more fully described in the aforesaid patent, that as the spinning operation proceeds, and the flexible connector I5 is progressively let off by the pick motion, the spindle rail unit moves by gravity to its lowermost or full yarn receiver position, the shaft |9 rotating in the direction of the arrow in Fig. 2, and that if the shaft |9 be turned in the opposite direction, it will act through the drums or sprocket wheels 25 and the flexible connectors 23 to raise the entire spindle rail unit.

The means illustrated for rotating the shaft Hi to raise the spindle rail unit by power are similar to those shown in the aforesaid patent. In this spinning frame, the draft roll 26 is driven positively from the draft roll 21 which is connected to the main drive of the machine, which is not shown, by means of bevelled gear connections to the shaft 28. Upon this shaft 28 is secured the bevelled gear 29 meshing with the bevelled gear 30 upon the end of the vertical shaft 3| mounted in the swinging bracket 32, which bracket is journalled on the shaft 28 between the hub of the gear 29 and the collar 33. Adjacent its lower end the shaft 3| has secured thereto a worm 34 adapted, as the bracket 32 is swung, to be engaged with or disengaged from the worm wheel 35 secured to the shaft IS.

The foregoing construction may all be substantially as described in the said Patent No. 1,824,? 88. The construction disclosed in said patent also provides a toggle mechanism for swinging the bracket 32 to bring the worm 34 into and out of engagement with the worm wheel 35 as required to raise the spindle rail unit and also a simple pawl and ratchet to maintain the spindle rail unit in its raised or dofling position. The present invention is disclosed herein as embodied in a simple and preferred form in mechanism of this general type.

A small shaft 36 extends along parallel with the shaft l9 and is journalled in suitable brackets on the end frame I, as, for example, at one end in the bracket 2| and at the other end in a small bracket 37. An arm 38 secured to this shaft and an arm 33 pivoted in the lower end of the bracket 32 are pivoted together to constitute a toggle mechanism. When the toggle is in full line position, as shown in Fig. 2, the worm 34 and worm wheel 35 are connected, and when the toggle is broken and moves to the position shown in the dotted lines, the bracket 32 is swung to disconnect the worm 34 from the worm wheel 35. The shaft 35 is provided with a suitable handle 40 by means of which the shaft may be rocked manually in one direction or the other to effect the connection and disconnection of the worm and worm wheel and this handle also serves by engaging with the stop 4| to define the full line or straight position of the toggle. The shaft 38 has also secured thereto an arm 42 in the path of an arm 43 adjustably secured to the shaft l9. Thus the arm 43 may be so positioned on the shaft l9 as to cause it to engage the arm 42 and rock the shaft 36, break the toggle and disconnect the worm 34 from the worm wheel 35 when the spindle rail unit has reached any desired or predetermined point of elevation.

A wide toothed ratchet wheel 44 is secured to the shaft I9 adjacent the bracket 2|. A pivot stud 45 is journalled in the bracket 2| secured to the frame and extends parallel with the shaft it). For this purpose the pivot stud 45 is shown as rotatably mounted on a journal pin 46 projecting from the bracket 2| and is held in place by a set screw 41 engaging an annular groove 48 in the journal pin. This pivot stud presents a section 49 eccentric to its pivotal axis and upon this eccentric section there is mounted the pawl which cooperates with the ratchet wheel 44. In the construction illustrated the pawl comprises two sections 55 and 5| of different length, the section 5| being shown as longer than the section 513 by half the length of a tooth oi the ratchet wheel. These pawl sections are loosely interlocked as by means of a stud 52 extending from the tail of the section 5| into a recess 53 in the tail of the section 50. Thus the pawl sections may act independently to engage the ratchet teeth but move together when thrown into or out of engagement with the ratchet wheel. The tails of the pawl sections are enlarged, as shown, to form weights which thus act to maintain the pawl sections against the teeth of the ratchet wheel when the pawl is in action. Cooperating stops on the pawl and the frame are provided to limit the upward movement of the pawl when in or approaching ratchet engaging position and for this purpose the pawl section 5| is shown as provided with a lug 54 and the bracket 2! with a rib 55.

The pivot stud 45 is provided with a suitable handle which in this caseis shown as an arm 55 projecting radially from its outer end, but the term handle is to be understood as including any suitabl means for rocking the pivot stud. The pawl is in ratchet-engaging position while the shaft i9 is being rotated to raise the spindle rail unit and in Fig. 3 the parts are shown in the position occupied when the spindle rail unit is at its predetermined uppermost raised position. When the power has been disconnected from the shaft 89 by the disengagement of the worm 34 from the worm wheel 35, the entire weight of the spindle rail unit and its load is thus held by the pawl engaging a tooth of the ratchet wheel, as shown in Fig. 3, Thus the spindle rail is locked in the predetermined raised position by the engagement of the pawl with the ratchet Wheel. The present invention enables this locking engagement of the pawl with the ratchet wheel to be released, notwithstanding the heavy load supported against the pawl. By turning the pivot stud 35, as by means of the handle 56, the eccentric section of the pivot stud acts to cam the pawl out of engagement with the ratchet wheel. Thus by the application of a very slight force applied to rotate the pivot stud, as by means of the handle, the pawl is moved back endwise notwithstanding the heavy pressure to which it is subjected. This may be done by swinging the handle through 180 to the position shown in Fig. 4. The operator may then readily flip the pawl into the position shown in Fig. 4 so that its weighted end will prevent reengagement of the pawl with the ratchet wheel.

When the operation of raising the spindle rail unit is to be initiated, the pawl must be in ratchet-engaging position. If it were not, when the spindle rail reached. its uppermost position and the power was disconnected, the entire spindle rail unit would fall a distance equal to the entire length of the yarn receiver and do great damage. The present invention prevents this occurrence by providing a safety guard. For this purpose the shaft 36 is provided at its end opposite the pawl with an arm 5'1 secured thereto and having a laterally projecting stud 58 and the tail of the pawl section 50 has loosely pivoted thereon a depending finger 59 having a tail 68. These parts are so proportioned that when the pawl is left in disengaged position, as shown in Fig. 4, the finger 559 will hang over the tail 58 of the arm 51 and in engagement therewith. It will be remembered that in order to initiate the raising of the spindle rail unit the shaft 36 is rocked by the operator as by the handle 56 but the safety guard prevents such rocking of the shaft and consequently the operator is at once apprised that the pawl is not in ratchet engaging position.

The operation of the mechanism thus illustrated and described as a preferred embodiment of the invention will now be clear. At the conclusion of the spinning operation when the yarn receivers are fully wound with yarn and doffing is to be effected, the spindle rail unit has reached its lowermost position under'the control of the builder motion and must be raised to dofling position where the full yarn receivers are removed and empty yarn receivers are placed upon the spindles. When in this raised position the spindle rail must be entirely out of control of the builder motion in order to effect the purposes of the invention, namely, to enable the formation of a bunch on each fresh yarn receiver with the lower edge of the bunch such as shown at Si in Fig. 6 at the lower edge of the subsequently wound yarn mass 62, or with the lower edge of the bunch such as shown at 63 in Fig. '7 below the lower edge of the subsequently wound yarn mass lit, or as shown in Fig. 7 with the entire bunch below the lower edge of the yarn mass. Accordingly the arm at is set on the shaft l9 so as to break the toggle 33, 39 and disconnect the power when the spindle rail has reached in its upward travel the required position out of control of the builder motion, that is, with the highest point of the builder cam l3 out of contact with the follower 12.

In initiating the operation of raising the spindle rail unit, the parts should be in the position shown in Fig. 3 and in dotted line position in Fig. 2. The operator then rocks the shaft 36 as by means of the handle iii. If the operator finds the shaft locked against rotation, it is at once recognized that the pawl has not been properly returned to ratchet-engaging position because the safety guard is preventing the rotation of the shaft 86. Thereupon the operator flips the pawl back into ratchet-engaging position and even if the pivot stud t5 has not been rotated. into ratchet-engaging position, the pawl will not swing by the ratchet wheel because of the cooperating stops 5 5 and 55 and the operator will rotate the pivot stud to proper position.

When the operator does rock the shaft 36, the driving power is connected to the shaft l9 by the engagement of the worm 3 3 with the worm wheel and at once the entire spindle rail unit is raised by power untilthe arm 53 acts to break the toggle and leave the spindle rail unit in its predetermined raised position entirely out of control of the builder cam.

The full yarn receivers are then doffed and the fresh yarn receivers placed in position on the spindles. The operator then allows the frame to run with the spindle rail unit remaining in raised position until the desired hunch is formed on each yarn receiver. During this operation 'the spindle rail remains stationary and when sufficient yarn has been wound and the builder cam has reached a position opposite the follower l2, readily determined by the operator, the operator withdraws the pawl from the ratchet wheel by rocking the pivot stud with the handle 56 and thereupon the spindle rail is restored to the control of the builder cam and the operation of spinning and winding the yarn mass proceeds in the usual manner.

If the bunch is formed in the position substantially as indicated in Fig. 6, while the high points of the builder cam might possibly just touch the follower on the builder arm, the pawl is not released from the ratchet wheel and the spindle rail unit remains in the bunch building position. If the operator in restoring the spindle rail unit to the control of the builder motion does so when the high point of the builder cam is not directly over the follower of the builder arm, the slight drop of the spindle rail unit to bring the follower into engagement with the builder cam is so slight as to do no damage.

The invention thus enables yarn receivers or bobbins readily to be wound with bunches positioned as described and as shown in Figs. 6 and 7, for example, and in a position where the yarn forming the bunch may be readily drawn off for attachment to the yarn on the leading end of a full yarn receiver or bobbin.
