22 Claims. (Cl. 21R-356) The invention pertains to winders oi.' the general type shown in Patent No. 1,267,977, `dated May 28, 1918, in which. a series of yarn masses or cheeses are wound to a desired diameter under the control of a Winder-tending mechanism or travelen More particularly, the invention aims to provide an improved mechanism for automatically determining the quantity of yarn wound on the cheeses.

Winders as heretofore constructed have embodied full-cheese measuring devices of a character such that without manual adjustment the machine is incapable of producing cheeses of more than one size. An important object of the present invention is to provide for the automatic production of cheeses containing diierent measured quantities of yarn.

A further object is to provide a measuring means operative automatically in the travel of 2O the Winder-tending mechanism to produce two or more different sizes of cheeses.`

Still another object is to produce a Winder in which the traveling mechanism is equipped with a cheese measuring means operative at spaced points in the travel of the mechanism under the control of two orimore adjusters to produce two or more sets or groups of cheeses with the cheeses of one group of a different predetermined diameter than the cheeses of the other group or glOllpS. Y

` The objects-of the invention thus generall stated, together with other and ancillary advantages are attained by the construction and arrangement shown by way of illustration in 05 the accompanying drawings and constituting a preferred embodiment of my invention.

In the drawings: Figure 1 is a fragmentary front elevational view of a Winder embodying my invention.

Fig. 3 is a fragmentary sectional View taken approximately in the plane of line 3 of Fig. 1, and (L- illustrating the means operative under the control of the cheese measuring device to limit the size of the cheeses by interrupting the winding of yarn thereon.

Fig. 4 is a fragmentary view in perspective illustrating the full cheese measuring'device and one of the adjusters therefor.

The Winder-tending mechanism comprises generally a framework or carriage 'I arranged to travel upon the mainy frame 8 of the Winder for `successive association with a series of winding units. For this purpose the latter is equipped il with a rack 9 with which meshes a gear I0 suitably driven from the traveling mechanism, the construction and arrangement being substantally as disclosed in said Patent No. 1,267,977. y

The means for measuring the cheeses is mounted on the traveling mechanism and comprises, as best shown in F'ig. 4, a feeler shoe II mounted on therearfend of an arm I2 and arranged for operative association with cheeses of which one Y only is shown at I3. Each of the cheeses is mounted on an arm I3a, in a manner wellknown in the art so as to be kcapable of swinging from a normal operative or winding position in driving Contact with a rotating drum (not shown) )(5 upwardly and thence outwardly into a thrownout position (Fig. y4:) for engagement by the feeler shoe I I on the traveling mechanism.

The arm I2 is pivotally mounted on a'shaft I4 and is adapted to be lowered and raised pe- 20 riodically to carry the shoe II toward and from at the Cheese I3. Such periodic motion of the` arm I2 isd'erived from a cam I5 constantly driven in theoperation of the traveling mechanism and having a roller follower I6.` The latter is mount- 25 ed on the rear end of an arm I'I fulcrumed at 21?- its forward end on a shaft I8. The rear end of said arm I1 is connected by a link I9 with the arm yI2 at a point adjacent its fulcrum on the shaft I4. IZa is a spring tending to swing the arm I2 toward the cheese` under the control le.: of the cam I5.

The cam I5 is mounted on a constantly driven vertical shaft 20 and makes onecomplete revolution in the movement of the traveling mechanism from one winding unit to the next. As clearly shownkin Fig.`4, the cam has` a depression 2|" therein and the arrangement is such that in its approach to a cheese to be` measured, the arm I2 is held raised to position the undersurface of the shoe I I in a horizontal plane above 40 the uppermost surfaces 0f the cheeses I3. Then as, in the travel of the mechanism, the shoe is positioned above the cheese, the depression 2l in the cam permits the descent of the shoe toward or into feeling relationto the cheese. u

The position assumed by the arm I2 under the control of the shoe I I when a cheesereaches a desired predetermined diameter, is utilized to discontinue the winding of additional thread on the cheese. To this end, the arm I2 has rigid therewith a depending arm 23 carrying at its lower end a gauge plate 24 having in its lower forward corner a notch `25; and associated with this gauge plate is a` control rod 26 operative when the gauge 55 plate and rod occupy a predetermined relation to initiate the operation of means for preventing the reserve thread from entering the knotter mechanism, thereby interrupting the operation of winding additional thread from the reserve bobbin into the cheese.

As shown in Fig. 4, the control rod 25 is disposed at right angles to the surfaceof the plate 24, so that the latter forms an abutment for engagement by the right hand end of the rod when disposed rearwardly of thc notch 25 in the plate. Adjacent the plate 24, the rod 26 is slidably supported in a guide plate 21. Alt its other end it is pivotally connected to a short arm 28 which for a reason presently to appear may be termed the latch arm. This arm has a pin 29 to which is connected a spring 3D acting to move the feeler rod 26 toward the gauge plate and through the notch 25 when permitted to dol so by the position of the plate.

The means for interrupting the winding operation in response to a movement of the rod 26 through thenotch 25 of the gauge plate 24, is arranged for actuation in the rotation of the shaft 20. This means comprises a throw-out finger 3| shown at the lower left o-f Fig. 4. As in prior machines, this finger is operative to engage and move out of the path of the knot-tying device (not shown), the reserve thread. leading from the bobbin. Herein, 'said finger 3l is pivotally mounted on a shaft 32 and has rigid therewith a slotted arm 33 for receiving a pin 34 on the end of an actuating arm 35. The latter is connected by a yoke 36 with a vertically spaced arm 3l, both arms being mounted to turn on a vertical shaft 38. The finger 3! is held in its normal position by a spring 38au tending to maintain a stop screw 39a on the yoke 36, in contact with a stationary part of the traveler frame. In Fig. 3, the linger 3| is shown out of its normal position indicated by dotted lines.

Also pivotally mounted on the shaft 38 is a bifurcated actuating member 39 carrying double roller followers lll] and 4l respectively engaging with cams ft2 and 43 fast on the shaft 20. These cams and rollers constitute a double roller cam mechanism of a well known character operating to impart a positive oscillating motion to the member 39, the arrangement being such that the member 39 is oscillated once for each revolution of the shaft 20.

When the control rod 26 is permitted to move through the notch 25 of the gauge plate by reason of the attainment of the cheese to a predetermined size, a connection is effected as an incident to such movement of the rod, between the actuating member 39 and the arm 3l connected with the throw-out finger 3l. For this purpose, the latch arm 2B is pivotally mounted on the forward end of the arm 31 and vcarries l rigid therewith `a latch dog 44. Alsoy the bifurcated actuating member 39 has rigid with one arm 45 thereof, a latch block 4B having an inclined surface underlying the dog M and formed with a groove lll adapted to receive the dog as incident to `the movement of the control rod by the spring 3i?. Normally the dog rests on the inclined surface of the block at the right hand side of the groove 4l so that the control rod 2E is held in its withdrawn position. In each revolution of the cam shaft ythe'latchblock is: actuated in timed relation tothe feeling movement of the shoe l I, but until the cheese has attained its predetermined size the gauge plate 24 is swung forwardly (Fig. 4) into a position such as to block the control rod 26 and thus prevent the dog 44 from entering the groove 4l'. When, however, the downward movement of the feeler arm. S2 is interrupted by a full cheese of a predetermined size, the notch 25 in the gauge plate is positioned to receive the control rod 26 and release the same to movement by the spring 3G, thereby causing the dog 44 to enter the groove lll. Thereafter the actuating member 39 is moved to the left in Fig. 4 to swing the arm 35 against the action of the spring 38a and thus move throwout linger 3l rearwardly (Fig. 3) and at the same time to retract the control rod 2t forreengagement with the gauge plate 24 which by this time has been moved forwardly by the cam l5.

The sensitive point of control governing the motion of the control rod 25 relative to the gauge plate 24 may, it will be seen, be varied by changing the relation of the rod to the plate, o-r more specifically by shifting the position of the rod relative to the notch 25 in the plate. According to my invention, this construction and arrangement is utilized in the automatic production of' two or more groups of yarn masses of different sizes, and this is attained in the present instance by a size determining or setting vmeans comprising a plurality o-f adjusters generally designated 43 (Figs. 2 and 4), and a cooperating' shifting device 43a mounted on the traveling mechanism and operatively connected with the guide plate 2l 7for the control rod 26 so as to determine the position of the latter relative to the gauge plate.

As best shown in Fig. 4, said guide plate 21 is carried by the lower end of an arm 49 pivotally mounted on the shaft I4 and rigidly connected by a yoke 59 with an opstanding arm 5l which in turn is connected by `a link 52 with a shift lever 53. The latter is mounted to turn on a vertical pivot pin 54 and carries at its free end a roller 55 mounted upon. the Winder-tending mechanism and movable in its travel into operative association with the adjusters 48. n

The adjusters Q3 comprise in the present instance, two plates 56 and 5l fast upon a block 58 suitably mounted for late-ral adjustment relative to the path of the'roller 55 by means of a bracket 59 secured to the windrer frame 8 (Fig. 1). The plates are spaced apart a distance conforming to the diameter of the roller and are formed with` opposing cam faces 56' and 51' diverging so as to receive and guide the roller into a predetermined position.

It will be observed that the two plates 56 and 5l are at all times fixed relative to each other but are bodily adjustable transversely of the path of movement of the roller 55 in the travel `of the Winder-tending mechanism. The two plates form between them a guideway for receiving the roller 55 and operate through the lever53, link 52 and arms 5l and 49 to determine the positionof the guide plate 21 and its control rod 25 relative to the gauge plate 24 as the latter reaches the end of its forward movement (Fig..4) in the operation of the cam l5 and the feeler shoe Il. As the Winder-tending mechanism approaches a given winding unit the guide plate 2l and rod 26 are positioned according to a desired predetermined size of the yarn mass to be produced at this unit. If the yarn mass has attained less than said predetermined size, the feeler shoe Il will upon its descent as permitted by the cam I5, cause the gauge plate 24 to `assume a position with the notch 25 forwardly of the rod 25. The rod is thus blocked against movement and the winding operation permitted to continue. On the other hand if `the cheese has attained its predetermined size the gauge plate 24 Will be limited in its forward movement so as to permit the passage of the rod 26 through the notch 25. When this occurs, the dog 44 Will be permitted to enter the groove 41 to effect a connection between the arm 31 and its actuating member 39 resulting in the interruption of the winding operation through the actuation of the throw-oir nger 3l.

Referring now to Figs. 2 and'4., it will be apparent that in the travel of the tending mechanism, the `position of the guide plate 21 and therefore of the control rod 26 relative to the gauge plate 24 Will be determined by the adjuster plates 56 and' 51 and that `by changing the relative positions of the adjusters 48 transversely of the path of travel of the roller 55 (Fig. 2) the control rod 26 will be automatically shifted at predetermined points by the adjusters 48 and thereby vary the sensitive control point which determines the size of the cheeses through the interruption of the winding operation. After movement into association With a given adjuster, the setting eiected thereby is maintained for succeeding winding units until readjustment occurs by engagement of the roller 55 with another differently set adjuster. Thus for each setting of the plate `21, the cheeses are wound to a size determined by such setting.

To insure the maintenance of the guide plate 21 in a set position after the roller 55 has passed through and beyond a given adjuster 48, a suitable retaining device is provided (Fig. 1). As shown (Fig. 1) this device comprises a plunger '60 mounted in a depending arm 6I rigid With the frame 1 and pressed by a spring 62 into frictional engagement with the surface of the guide plate 21. l A

It Will be observed that my invention pro-vides for the automatic production in a single Winder of cheeses of two or more different sizes and therefore containing different measured quantities of yarn. In practice, the several adjusters `48 are first set according to the diierent sizes to Which the cheeses are to be wound, four adjusters being shown in Fig. 2, so that four groups of cheeses of different sizes may be produced. According to the setting of these adjusters, the guide plate 21 is positioned to govern the operation of the control rod 26 in response to the movement of the gauge plate 24 which in turn is responsive to the size of the yarn masses, for the purpose of interrupting the Winding operation 'and thereby limiting the size of the yarn masses being wound. As the Winder-tending mechanism moves from one Winding unit to the next, the feeler shoe Il is lowered by the operation of the cam l5 and moves the gauge plate 24 forwardly a distance depending upon lthe extent of downward movement of the shoe H as permitted by the size of the cheese when the cam follower I6` enters the y depression 2| of the cam l5.

As the cheese approaches its predetermined maximum diameter, the extent of movement of the gauge plate 24 is limited by the engagement of the shoe with the cheese, yand if the cheese has attained its predetermined maximum diameter, the control rod 26 is permitted to move under the influence of its spring 30 through the notch 25 of the gauge plate. When this occurs, the latch dog 44 enters the groove 41 in the latch plate 46, and in the ensuing oscillatio-n of Vthe bifurcated member 39, the arms 31 and 35 are operated to swing the throW-outnger 3| into the position shown in dotted lines in Fig. 3. .In this position of the linger, the reserve thread 1s deected so as to be prevented from entering the knot-tying mechanism and thereby discon.

tinues the Winding of yarn onto the yarn mass as explained in the aforesaid Patent No. 1,267,977.
