21 Claims. (01. 51-215) This invention relates to new and useful improvements in combined doubling and twisting machines and deals more particularly with modifications applicable to conventional down 6 ring spinning machines-of the so-called 53 type,

which will adapt said machines to the production of finished lustrous yarn packages.

The primary object of this invention is to provide a machine of the above-mentioned type 10 in which the several spindles and their associated stop motion mechanism are divided into a plurality of groups, with any desired number of spindles in a group, so that the building of the packages and the stopping of the spindles, as a'resultv of breakage of single ends or completion of packages, may be efiected by mechanism individual to each group.

A furtherimportant object of the invention is to provide traverse or builder motion mechanism of such character that the formation of packages .on a small number of spindles, controlled as a group, may be interrupted at any point in the building'thereof and again resumed at a later time without affecting the final contour of the interrupted packages and without interfering with the continuity in the production of any of the remaining packages. of the machine.

' A further important object of the invention is to provide traverse or builder motion mechanism of such character that the ring spinners for all of the spindles of a machine will partake of traverse strokes of the same amplitudewhile Y the' package building movements of the ring spinners will be efiected'by mechanism which is duplicated in accordance with any desired grouping of the several spindles.

Another object of the invention is to provide stop motion mechanism for a machine of the 40 above-mentioned type which will operate to stop the several spindles of a correlated, group, which forms only a'small portion of the tgtal number of spindles in the machine, either} upon the breakage of any single end going to any of the spindles in said group or upon completion of the building of packages on the spindles of the group. I 7

Other objects and advantages of the invention will be apparent during the course of the following description.

' The invention now will be described in con-' nection with the drawings illustrating an exemplary adaptation thereof vto a conventional 35 5B doubling and spinning frame. The essential portions of the 53 machine which have been retained without modification first will be referred to briefly. 4

Referring particularly to Figs. 1 and 2, the 40 reference character A designates in its entirety 'the frame portion of the machine which has the usual overhead creel structure B properly mounted thereon. A spindle supporting rail ex tends longitudinally of the machine and sup- 45 ports the two parallel rows of swing spindles D. The spindles are adapted to be driven by the conventional, continuous belt E and relative to which the spindles are swung into'and out of driving relation by the action of .the spring 50 pressed stop motionrodFr A ring rail G extends longitudin 'yfalong each side of the machine. Both of-Ithese ring rails are adapted to partake of a predetermined, unifor'm vertical reciprocatory motion imparted thereto by a con- 55 ventional heart can traverse mechanism which is designated in its entirety by the reference character H, as best shown in Fig. 1. The traverse mechanism H is driven from the feed roll drive shaft J in the conventional manner, as illustrated in Fig. 1. Feed roll mechanism for delivering the single ends from the creels B to the spindles D is illustrated anddesignated by the reference character K.

The parts .thus far referred to are entirely conventional and form no part ofthe present invention, except as the action or operation of the same is affected or modified by the adaptation of the present invention thereto.

The present invention modifies the normal mode of. operation of a' conventional 53 doublingand spinning frame to the extent that it divides the spindles and their associated instrumentalities into a plurality of independent groups, with any desired number of spindles to a group, and effects a control over the spindles, their associated spinner'rlngs, feed rolls and stop motion devices, so that the action of each group of spindles will be independently controlled with the result that'flnal packages may be wound on the several spindles by means of a single cycle form of wind, and the formation of packages on the spindles of any group may be interrupted at any time in the building thereof and again resumed at a later time without affecting the final contour of the interrupted packages and without interfering with the continuity in the production of any machine.

In Fig. 3, three spinner rings III are illustrated as being interconnected and supported by a ring bar H by means of the lateral flanges l2 of the rings being adjustably fastened to the lateral arms l3 which form a part of the ring bar I; This ring bar couples the three rings together to cause these rings to constitute a group. It is to be understood that any'desired number of rings may be coupled together to form a group. All of the groups of rings are intended to partake of the uniform, vertical reciprocatory movement of'the ring rails G to effect the traverse of the remaining packages of the movement of the rings relative to the spindles D.

The building'of the packages by advancing the traverse movement of the rings longitudinally of the spindles is efl'ected, however, by builder motion mechanism which is carried by the ring rails and is provided one such mechanism for each group of spinner rings. This individual group builder motion mechanism will effect relative movement of the rings ID with respect to their associated ring rail G. For the purpose of providing stability for the rings, each one of the rings is provided with a laterally projecting bifurcated finger H which receives between its furcations a perpendicular guide rod l5 mounted on the ring rail G.

The individual group builder motion mechanism will be described in detail in connection with Figs. 2, 3 and 5 to 7 inclusive. The ring rails G have mounted thereon one reversely bent angle bracket l6 for each individual group builder motion mechanism. Each angle bracket It has formed at its inner end an upstanding arm I! carrying a bearing stud l8 on which .is pivotally mounted a pawl carrying lever l9, see Figs. 5 and 6, which lever in turn carries a pivot bearing for the pawl 2|. Coiled around the bearing stud I8 is a. coil spring 22 which functions to lift the lever l9 and return' the pawl 2| to the starting point of its stroke, after actuation, to permit the pawl to reenga'ge one of the teeth 23 on the 1,6 is provided with a downwardly extending bushing 26 which is apertured to loosely receive the threaded rod 21. The bore of the wheel hub is smooth or unthreaded, and movably receives within an opening 28, formed in its'side wall, a knife blade thread providing element 29 which is pivoted to the hub 30 and is retained in its threaded bar engaging position by means of the spring 3|, see Fig. '7. It will be appreciated that this knife blade element 29 acts as a thread connection between the hub 29 and the threaded bar '21 and this thread connection may be severed or broken when desired by merely pivoting the blade element 29 about its pivot 30, against the tension of the spring 3|. This severance of the threaded connection between the wheel hub 25 and the threaded bar 21 will permit the ratchet wheel 24 and its hub 25 to be moved manually along the length of the rod and vertically with respect to the angle bracket |6 which is carried by the ring rail G. Such a manual and rapid manipulation of the ratchet wheel"24 relative to the bracket I6 and the ring rail will facilitate dofllng of the packages which have beenformed on the spindles associated with the group of spinner rings controlled-by the builder motion mechanism being described. This action will be more apparent as the description of this builder motion mechanism proceeds.

Itthus will be seenthat rotation of the ratchet wheel 24, effected through the medium of the pawl 2|, will function to advance the rod 21 vertically through" the angle bracket I6 and the hub 25 of the ratchet wheel 24. It will be observed, however, that the bracket |6, ratchet wheel 24, and pawl 2| with its actuating lever l9 are all carried by the ring rail G, and that these elements jointly partake of the uniform vertical or reciprocatory motion imparted thereto so that the movement of the threaded bar 21, togetherwlth the elements carried'thereby, is superimposed uponthe movement ofv the ring rail G.

The pawl actuating lever I9 is adapted, when the ring rail G reaches the upper limit of its stroke, to contact the lower face of the cam 32 and'to be moved, by this engagement, about the pivot It to cause the pawl 2| to advance the ratchet 24 a predetermined distance. It is apparentjthat the distance of movement of the ratchet wheel 24, efiected by the pawl 2|, is dependent upon the magnitude of the movement of the free end of the pawl carrying lever l9 and that the latter movement is dependent upon the position of the cam 32. This cam 32 is carried on the stop motion rod F, see particularly Figs. 5 and 6, through the medium of the collar 33, which is adapted to be locked in any desired position of adjustment by means of the set screw 34. The collar 33 carries the bearing pin 35 on which the cam 32 is mounted. This cam 32 has formedintegrally therewith a ratchet 36 while a pawl carrying member 31 is fixedly mounted upon the bearing pin 35 and carries the pawl 38. The ratchet 36 and pawl 38 function to hold the cam 32 in any particular position to which it may be I lifted. The cam 32 is adapted to controlthe initial winding of the cone on the spindle and isv position, the cam arm the path of movement of the actuating arm of the cone. It will adapted to be actuated for this purpose through the medium of the arm'39.

Returning now to the threaded rod 21, it already has been observed that this rod is adapted to partake of two movements; first, the uniform reciprocatory movenmt of the ring rail G and, second, the step-bytep vertical movement timparted thereto by actuation of the ratchet wheel 24. The rod 21 has clamped thereon a ring supporting bracket or collar 40, held in position on the rod 21 by a set screw 4|. This bracket or collar 40 is formed integrally with the ring bar I I and cooperates with the ring bar. and branch arms l3 for locating the .various rings Ill, connected to the arms l3 over the ring rail G and in coaxial alignment with the associated spindles D. As clearly shown in Fig. 5, the ring I is provided vwith a conventional traveler 42.

The threaded rod 21 additionally carries a collar 43 which is 'located above the point of attachment thereto of the bracket 40 and is adjustably secured to the rod 21 by means of the set screw 44. This collar carries the L-shaped arm 45, see particularly Figs. 2, 3 and 5, which is adapted, on the upward stroke of the ring rail G during the initial building of a cone, to contact the arm 39 and impart thereto a slight movement to efiect turning of the cam 32 about the bearing pin 35. The configuration of the cam 32 and the manner of its actuationthrough the medium of the arms 39 and 45 control the building of the base of the cone on a spindle. The building of a small base cone at the bottom of the spindle is accomplished in accordance with the present invention by so correlating the configuration of the cam 32 and the action of the pawl 2| on the ratchet wheel 24 that, during the initial building of the cone, the spinner ring I0 is advanced vertically of the spindle in a stepby-step movement of progressively decreasing extent.

The vertical displacement of the ring III with respect to the ring rail G, effected by each contact of the pawl actuating lever |9 with the cam 32, diminishes until the cam '32 and the arm 39 have been turned until the positionoccupiedjby the right hand cam in Fig. 2 isobtained; In this 39 is completely out of rod 21, and accordingly the cam 32 remains stationary. The arm of the cam ,32 remains stationary and the throw of the pawl 2| then is constant, causing the'threaded rod 21, carrying the ring Hi, to thereafter advance at a uniform rate during the building of the remainder be observed that the pivot bearing l8 for the pawl actuating lever l9 and the" pivot bearing 35 for the cam 32 occupy, throughout the operation of the builder motion,

apredetermined uniform relationship and that the throw of the pawl 2| is controlled entirely by the position of the cam 32.

In Figs. 1, 2 and 3, the stop motion rods F which are associated with the three spindles D and the spinner rings l0 which are interconnected to operate in a group'by one ring bar II, are all interconnected to likewise operate as a group by means of a horizontally extending bar 46 which is connected to the three stop motion rods F by the coupling members 41. The stop motion rod F for the middle spindle of the group carries the cam 32 and its associated elements. As clearly shown in Fig. 3, the builder motionmechanism, most completely illustrated in Fig. 5, is associated with the ring bar so that it will cooperate with carried by the pivot length of the packages.

the cam 32 carried by the center stop motion rod F. It has been pointed out heretofore that the cam 32 is carried by a stop motion rod F. This is particularly advantageouslfor the reason that when any one of the three stop motionrods, coupled by a horizontal rod 46, is released and elevated, in a manner to be explained at a later point, it carries with it the remaining two stop motion rods and particularly the rod F which has mounted thereon the cam '32. This cam, therefore, is elevated completely above the upper limit of movement of pawl actuating lever l9 so that when the stop motion rods are raised, no further actuation of the pawl 2| and ratchet -=wheel 24 occurs. Accordingly, adjustment of the three rings Ill, actuated as a group by the particular builder motion mechanism under consideration, relative to the ring rail G is stopped until the three affected stop motion rods are restored to their normal operative position. As soon as the three afiected stop motion rods are returned to their normal positions, the cam 32 is again rendered effective to actuate the pawl carrying lever l9 and thereby again causes a step-by-step vertical movement of the threaded rod 24 and its associated three spinner rings l0.

It is thus apparent that if the formation of any group of packages is interrupted at any time during the building thereof, such formation again can be resumed without in any way affecting the contour of the group of final packages since, during the period that the building is interrupted, the three rings of the stopped spindles do not change their positions with reference to the The fact that an individual builder motion is provided for each interconnected group of spindles, therefore, makes it possible to interrupt the building of the pack- ,ages on the'group of spindles without in any way affecting the ultimate contour of theseziriterrupted packages or without interferingin any way with the continued building of. the packages on any of the remaining spindles of the machine. It will be apparent, therefore, that-the various groups of spindles may at any time have packages being built thereon which are at many different stages of development as the building of each group of packages is entirely independent of any 'of the remaining groups. i

The stop motion rods F, with the exception of being interconnected to operate in groups, function in response to the breakage of any single end coming from the supply spools on the creel B. This group operation of the stop motion rods now will be explained:

Referring particularly to Figs. 2 and 4,. it will i be seen that the conventional threadguide or drops 48 are provided in suitable numbers for each one of the spindles. These various thread guides are all pivoted at Hand are normally retained in the position illustrated in Fig. 2 when unbroken single ends are feeding through the same to the various ring spinners. Upon the breakage of any single end, its thread guide or drop 48 is permitted to swing inwardly for lowering its end 50. This downward movement of the end 50 actuates a latch release member 5|, through the medium of a horizontally extending.

a rod 52 which extends the full width of the several thread guides 48 cooperating with the spindle to which the'broken single end was being fed. Actuation of the latch release member 5| causes pivotal movement of the same about the pivot 53 for moving the inner end of the member 5| into the path of movement of the rockably actuated cam 15 arm 54 which is constantly driven from the source of power employed for driving the entire machine. When the inner end of the latch release member 5| is engaged by the rocking cam 54, the

member 5| is moved longitudinally and results in pivoting of the latch 55 to the lower end of which the member 5| is pivotally connected. Fig. 4 discloses the fact that all of the latch members 55 for an interconnected group of spindles and their associated devices, are interconnected to operate in unison by means of the longitudinally extending rod 56 to which all of the latch members 55 are rigidly attached. Each latch member 55 is adapted normally to engagethe hooked end of an arm.51. which is carried by the upper end of its associated stop motion rod F.

It now will be seen that when any thread guide or drop 48 is released by the breaking of its single end, all of the latch members 55, which are interconnected by a rod 56, will be actuated and the stop motion rods F associated with the actuated latch members 55 will be released. The conventional springs, provided for all of the stop motion rods F which have been released will cause these released rods to move upwardly for braking the drives to the feed rolls K and for shifting the spindles D out of driving relation with the belt E and into engagement with braking devices for the spindles in the manner conventional for a' 53 machine.

By considering Figs. 1, 2 and 3, it will be seen that each one of the threaded rods 2'! is provided at its upper end with a laterally extending arm 58 which is moved into engagement with the lower end of a stop motion release rod 49 when any one of the rods 21 has been moved sufiiciently to carry I its three associated spinner rings ill to the level of the upper ends of the packages which are being built on the associated spindles D. This engagement between the arms 58 and the associated rods 59 cause these rods to move upwardly until they engage the inner ends of the associated member-s 5|. These members 5| are then caused to move into the path 01' the cams 54 with the result that the members 5| are actuated to trip their latch members 55. The interconnected stop motion rods F then will be permitted to'move upwardly for stopping the building of packages on the associated spindles D. This action takes place when the packages have been completely built on these spindles.

Fig.'1' discl oses the conventional pedals 55 which are employed for depressing the stop motion rods F and returning the feed rolls K and spindles D to their normal operative positions in the usual manner. In the present modification of the conventional 53 machine, one pedal 50 is employed for each interconnected group of stop motion rods F. The pedal 50, preferably, is operatively connected to the middle stop motion rod of a group.

Fig. 8 discloses a modification in the grouping of spinner rings; In this grouping, five rings III are connected by the arms |3a to a ring bar Ila, in the same manner as that described in connection with Figs. 3 and 5.

Due to the large number of rings arranged in a' group, two builder motion mechanisms are employed for actuating the ring bar Ila. These step-by-step builder motion mechanisms are con-. nected to the ring bar ||a by means of collars 40a. which are attached to the threaded rods 21 of the builder motion mechanisms in the same manner as that described in connection with Fig. 5. The stop motion rods F for these five grouped rings are interconnected by a single rod 46a.

As the step-by-step builder motion inechanisms employed for synchronously operating both ends of the ring ,bar a are identical in construction with the mechanism disclosed in detail in Figs. 3 and 5 7 inclusive, these devices of Fig 8 will not be described in detail. The same reference numerals employed for, indicating like parts in Figs. 3 and 5-7-inclusive will be applied to Fig. 8.

In my application Serial No. 102,574 filed Sept. 25, 1936, I have disclosed a modification of a conventional 5Bi-machine which consists primarily of providing a step-by-step builder motion mechanism for each individual spindle. It will be appreciated that in such a machine one builder motion mechanism must be provided for each spindle of a machine. This not only adds materially to the initial cost of a machine but also increases the maintenance burden. As these individual builder motion devices are carried by the ring rails G, the provision of one builder motion for each spindle adds materially to the load or Weight which must be carried by the ring rails.

In the present invention, the number of individual builder motion mechanisms is materially reduced. The modification of the invention disclosed in Figs. 1-7 inclusive requires one builder motion mechanism for each group of three spindles. The form of the invention disclosed in Fig. 8 requires two builder motion devices for each group of five spindles. It will be appreciated that I do not desire to be limited to three spindles to a single builder motionmechanism or five spindles to two builder motion devices. Other groupings and combinations clearly will fall within the invention as disclosed herein.

From the foregoing description, it will be apparent that I have devised a novel improvement that may be applied toconventional multiple down ring spinning machines to convert the same into instrumentalities capable of effecting the individual building of groups of packages in conjunction with group actuating traverse mechanisms. It will be observed additionally that, in accordance with the present invention, each group of packages is under individual control without respect to any of the remaining packages and that the building of any given group of packages may be interrupted without interfering with.

the continuous building of the remaining packages.

It further is to be noted that I have provided for the building of an individual type of yarn base on each of the spindles arranged in a group regardless of the stage to which the building of packages on any of the other spindles may have progressed and that I additionally provide for the stopping of the spindles of any group and their associated builder motion mechanism upon completion of any. individual group of packages.

It is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
