9 Claims. 1

This invention relates to textile machinery and more especially to an apparatus for upsetting, breaking or crimping yarn which is to be subjected to sizing and dyeing operations after the yarn has been wound into tubular packages or cakes which are usually cylindrica1lyshaped. However, it often happens that the turns of yarn which are wound adjacent opposed ends of the cylindrically-shaped packages or cakes are placed under greater tensionthan the yarn wound about the medial portion of the package. It is evident that sizing solutions or dyes would more easily penetrate bers of yarns which are wound loosely than fibers of yarns which are wound tightly at opposed ends of the packages of yarn and it often happens that the turns of yarn forming the opposed endsof the cylindrically-shaped or conically-shaped packages would not be fully penetrated by the dyes or sizing solutions with the result that the yarn in each package is not dyed or treated uniformly throughout its length which, in many instances, would necessitate discarding the same.

It is, therefore, the primary object of this invention to provide apparatus for upsetting opposed ends of cylindrically or conically-shaped packages of yarn so as to relieve thetension in the yarns at the outer edges of and at the opposed ends of each package so the packages may subsequently be subjected to a dyeing, sizing or any other treating operation wherein the dye or other solution will penetrate the fibers of the yarn in each package uniformly throughout the package. i

It is another object of this invention to provide an apparatus for automatically breaking the opposed ends of cones of yarn which apparatus has at least one pair of cup-shaped members adapted to t over the opposed ends of a cone of yarn, whereby cones of yarn may be moved successively between said cup-shaped members and said apparatus also being provided with means automatically operable to cause said cupshaped members to move toward each other to compress or break the ends of the cone of yarn disposed therebetween and also having means for releasing said cone of` yarn from between said cup-shaped members after compression.

It is another object of this invention to provide a machine for automatically upsetting, breaking or crimping opposed ends of packages of yarn which comprises a lower continuously moving conveyor and an upper continuously moving conveyor which moves in synchronization with the lower conveyor and each of the conveyors having a plurality of spaced cup-shaped members or dies thereon having concave faces on the side thereof remote from the conveyor. The lower conveyor preferably extends a substantial distance beyond the upper conveyor and each of the` dies or cup-shaped members has a spindle extending outwardly from the center of the concave face thereof which is adapted to receive a tubular package of yarn. Then packages of yarn are successively placed on the cupshaped members on the lower conveyor and the packages of yarn pass beneath the upper conveyor and the coinciding cup-shaped members on the upper conveyor engage the upper ends of the packages of yarn under pressure to thus cause the turns of yarn at opposed ends of the packages to be rolled upon each other thus upsetting the same and relaxing the tension thereon. It is evident that the conveyors necessarily converge slightly towards each other from the point at which the packages are first engaged by the cup-shaped members on the upper conveyor to where the packages move out of range of the upper conveyor, to thus cause the pressure to be applied to opposed ends of the packages gradually. l

It is another object of this invention to provide apparatus of the type described and which is adjustable to accommodate packages of yarns of varying size.

Some of the objects ofthe invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings in which- Figure 1 is a side elevation of the machine showing the same operating upon a plurality of packages of yarn;

Figure 2 is an enlarged fragmentary side elevation showing one of the dies associated with the lower conveyor, with parts in section;

Figure 3 is a top plan view of the machine looking down from the top of Figure 1;

Figure 4 is an elevation with parts in section looking substantially along the line 4-4 in Figure 1;

Figure 5 is a side elevation of the machine looking at the opposite side thereof from that shown in Figure 1 but. omitting the cup-shaped members and yarn packages for purposes of clarity; a

Figure 6 is an end elevation looking at the f right-hand end of Figure 1 with the upper portion thereof being broken away; Y Figure '7 is an enlarged fragmentary elevation of one of the cup-shaped members associated with the corresponding conveyor chain and showing a package of yarn in association therewith, and being taken looking substantially along the line 1 1 in Figure 3;

Figure 8 is a fragmentary vertical sectional view looking substantially along the line 8-8 in Figure 6 but showing the lower end of the corresponding package as it is forced into the die to upset the lower end thereof.

Referring more specifically to the drawings, the numeral broadly designates the frame of the machine which comprises spaced transverse frame members and |2 which are shown in the form of angle bars, and each of which may be provided with a plate I3 secured at the lower end thereof as by Welding. Thesey transverse frame members II and I2 are adapted to be secured to 'a floor F or the like by any suitable means such as bolts I4 which penetrate the angle bars II and I2 and also penetrate the plates I3.

A pair of upstanding transversely-spaced frame members in the form of angle bars |5 and I6 are welded at their lower ends intermediate the ends of the horizontally disposed frame member II and are bridged at their upper ends by a horizontally disposed frame member I1. At the rear or left-hand end of the machine, in Figure l1, a pair of upstanding frame members 2| and 22, in the form of angle bars arewelded at their lower ends intermediate the ends of the rear transverse frame member I2 and these frame members 2| and 22 extend upwardly.

The rear ends of horizontally disposed

frame members

23 and 24 are welded to the respective vertically disposed frame members 2| and 22. The horizontally disposed

frame members

23 and 24 are spaced upwardly from the lower ends of the frame members 2| and 22, respectively, and extend forwardly substantially beyond the vertically disposed frame members |5 and I6 and are suitably secured at their front ends, as by welding. intermediate the upper and lower ends of respective vertically disposed

frame members

25 and 26. The lower end of each of the

frame members

25 and 26 has a plate 21 suitably secured thereto, as Aby welding, which is penetrated by -suitable bolts 28 for securing the same to the floor.

The upper ends of the vertically disposed front

end frame members

25 and 26 are bridged by a horizontally disposed frame member 3| which is cut away, as at 32 (Figure 3), to provide clearance for the cup-shaped members on the lower conveyor to be later described. The vertically disposed front

end frame members

25 and 26 are bridged intermediate their ends by a horizontally disposed frame member 33, the frame members 3| and 33 being welded at opposed ends thereof to the vertically disposed

frame members

25 and 26.

Welded to the upper ends of the vertically disposed

frame members

25 and 26 are the ends of a pair of lower conveyor

support frame members

34 and 35 which are shown in the form of angle bars which extend upwardly and rearwardly at an angle and are welded intermediate their ends to the vertically disposed side frame members I5 and I6 and are welded at their other or rear ends to the vertically disposed side frame mem-` bers 2| and 22. The angularly disposed lower

conveyor support members

34 and 35 are bridged by a plurality of spaced transverse frame members 36 to the upper surfaces of each of which a pair of spaced substantially vertically disposed track support members 31 and 38 are welded,

' ignated at 45.

v The

conveyor chains

43 and 44 are mounted at the front of the machine on respective sprocket wheels 45 and 41 which are xedly mounted on a common shaft 50 which is rotatably mounted in bearing blocks 5| of a suitable take-up mechanism broadly designated at 52. Each take-up mechanism 52 may comprise a substantially inverted U-shaped member 53 suitably secured to the corresponding angularly disposed lower

conveyor support members

34 and 35 as by bolts 54.

Each U-shaped member 53 has opposed ends of a threaded shaft 55 rotatably mounted therein which shafts threadably penetrate the corresponding bearing block 5| and opposed ends of which project beyond the members 53 and are adapted to be engaged by a suitable hand tool for rotating the threaded shaft 55 and to thus vary the relative position of the bearing blocks 5| for taking up slack in the

conveyor chains

43 and 44. Any suitable conveyor take-up mechanism may be used if desired.

The

conveyor chains

43 and 44 extend longitudinally of the machine and are supported by the tracks 4| and 42 and are mounted at the rear of the machine on respective sprocket wheels 63 and 6I which are fixedly mounted on a horizontally disposed lower conveyor drive shaft 62 rotatably mounted in bearing blocks 63 secured to the respective vertically disposed frame members 20 and 2| by any suitable means such as bolts 64 (Figure 1).

Referring to Figure 5, it will be observed that the lower conveyor drive shaft 62 also has a sprocket wheel 66 xedly mounted at one end thereof on which a sprocket chain 61 is mounted. The sprocket chain 61 extends downwardly and forwardly at an angle and its lower portion is mounted on a sprocket wheel xedly mounted on a reducer output shaft 10 which extends from a suitable speed reducer 1|. This speed reducer may be of a type such as is manufactured by Boston Gear Works of Boston, Massachusetts,

and such as is shown in their catalogue No. 54 on page 213 and which is known as a Type U Boston Reductor. It is evident that there are many different types of speed reducers which may be employed in the capacity of the reducer 1| shown in Figures 1 and 2, and the reducer 1| is shown for purposes of illustration only.

This reducer 1| also has an inpntshaft 12 thereon on which a pair of V-pulleys 13 are fixedly mounted. Suitable V-belts 14 are mounted on the pulleys 13 and extend inwardly on the apparatus and are also mounted on coinciding pulleys 15 fixedly mounted on a motor shaft 16 of a suitable electric motor 11. The electric motor 11 has a suitable cable 88 connected thereto and extending therefrom to a manually operable electric switch 8| suitably secured on a portion of the frame, such as the vertically disposed side frame member I5, and from which another cable 82 extends, the cable 82 has

wires

83 and 84 therein which extend to a suitable source of electrical energy, not shown.

The reducer 1| is secured by any suitable means, such as screws 86 (Figure 5), to a drive unit support plate 85 welded to the upper surfaces of the longitudinally extending

frame members

23 and 24. The electric motor 11 is suitably secured. as by bolts 81 (Figure 6) to the upper surface of a motor support plate 90 which is pivoted atone end thereof, as\at 9|, on the drive unit support plate 85 and thelfend of the plate 90 remote from the pivot point 9| is slidably penetrated by an adjustment bolt 92 which also slidably penetrates a block 93 projecting outwardly from and being welded to the drive unit support plate. The plate 90 is held in a raised position at its end remote from the pivot point- 9| by the v-belts 14 extending between the

pulleys

13 and 15 and the bolt 92 is tightened or loosened to increase or decrease the tension in the V-belts 14 as desired.

The

lower conveyor chains

43 and 44 support suitable dies or cup-shaped members, each of which is broadly designated at and each being substantially annular or circularly-shaped and being provided with a substantially hemisphericalor concave cavity |0| therein (Figures 2, '7 and 8). The cup-shaped members or dies |00 may be of any desired size to accommodate any i its upperend, as at ||6, so that it-may easily desired size of cone and for purposes of illustray `\-tion, the dies shown in Figures 3, 4 and 6 are shown as being of a larger size than the dies shown in Figure 1. `Y d Referring to Figures 2, 7 and 8, it will bcobserved that the outer surface of each of the dies |00 is substantially convex and has a projection |02 extending from the lower surface thereof and has lateral projections |03 on opposed sides'thereof which are provided with substantially triangularly-shaped depending portions |04 at the outer ends thereof which, as shown in Figure 2. are adapted to extend between adjacent rollers |05 of each of the

conveyor sprocket chains

43 and 44, the purpose of which will be presently described. n

Each of the

lower conveyor chains

43 and 44 is provided with a plurality of special spaced links |06 which extend outwardly substantially from the

respective conveyor chains

lower conveyor chains

43 and 44. It might be stated that, although the screws ||0 serve in securing the respective dies |00 to the

conveyor chains

43 and 44, the dies `|00 may pivot slightly on the respective screws ||0. Thus, the projections |04 are provided on each of the outwardly projecting portions |03 of the dies |00 to permit a limitedamount of pivotal movement of the respective dies relative to the conveyorchains 43 and 44 and these projections |04 engagethe adjacent rollers |05 of the

conveyor chains

43 and 44 to permit but limit pivotal movement of the dies |00. The reason for permitting this pivotal movement of the dies |00 will be later described. Now, each of the dies |00 is adapted to support a package or cone of yarn indicated at P, the particular packages of yarn illustrated having a plurality of turns of yarn wound about a tube I2 of substantially the same length as thatv of the package P, it being well known to those familiar with the art that substantially all packages of yarn are wound about a tube such as the tube I2 or on a cone or other similar member. Therefore. each of the dies |00 is provided with a cavity I3 which is disposed in the bottom of the hemienter the tube ||2 as the package of yarn P is placed thereon by an operator. It will be observed in Figure 8 that the cavity I3 is substantially larger than the pin ||4 to accommodate pins of larger diameter than the pin ||4 since the internal diameter of the tubes ||2 may vary from, say, of an inch in diameter to as much as 1% inches in diameter and, thus, the pilot pin .I |4 may be replaced by pins of a different diameter in accordance with the size of the tubes in the cones or packages ogyar/n being processed.

It will be observed that th/pilot pin ||4 preferably extends substantially above the upper edge of the die or cup-shaped member |00 in Figure 8 so as to be readily accessible tothe operator and to facilitate the placing of a tube ||2 thereover.

It is thus seen that as the lower conveyor moves about the sprocket wheels in the manner described, packages of yarn may be placed in the ldies 00 at the intake at front of the machine and be carried rearwardly or to the left in Figure 1. As the packages P move through the machine they are compressed in a, manner to be described.

lower conveyor chains

43 and 44.

Since the upper or second cup-shaped members or dies |23 are substantially identical to the lower cup-shaped members or dies |00, the same reference characters shall apply to those parts of the dies |23 which are identical to the dies |00 with the prime notation added. It might be stated that the pilot pins ||4' in the dies |23 should preferably be of substantially less length relative to the dies |23 than the pins ||4 in the dies |00 since they are Vonly employed in centering the upper end of the packageof yarn in the die |23 as it moves along with the lower reaches of the upper conveyor chains |2| and |22. Also, if the pilot pins |4 in the upper die |23 were of the same relative length as the pilot pins |4, they would probably enter the package of yarn to one side of the tube |2 as a result of which the corresponding package of yarn P would not be positioned in axial alinement with the center of the corresponding dies |00 and |23.

The upper conveyor chains |2| and |22 are mounted at the rear of the machine on respective sprocket wheels |24 and |25 which are xedly mounted on a horizontally disposed idler shaft |26 rotatably mounted at opposed ends thereof in bearing blocks 5|' which are parts of take-up mechanisms broadly designated at A52', these takeup mechanisms 52' being identical to the take-up mechanism 52 except being of lesser length and bearing the same reference characters with the prime notation added and a. further description thereof is/ deemed unnecessary. The take-up mechants/ms 52' are secured to the rear ends of substantially horizontally disposed upper conveyor support frame members |30 and |3| which extend forwardly and terminate adjacent the corresponding vertically disposed frame members and I6. The frame members |30 and |3| each has a bearing block |32 suitably secured to the upper surface thereof as by bolts |33, these bearing blocks |32 being mounted on a transverse upper conveyor drive shaft |34.

The upper conveyor drive shaft |34 is rotatably mounted at opposed ends thereof in bearing blocks |35, there being one of these bearing blocks suitably secured to the inner surface of each of the vertically disposed frame members |5 and I6, by any suitable means such as bolts |36. It will be observed, in Figures 3 and 5, that the upper conveyor drive shaft |34 extends substantially beyond the outer surface of the vertically disposed frame member |5 and has a spocket wheel |31 fixed thereon on which .a spocket chain |40 is mounted. This sprocket chain |40 extends downwardly and is mounted on a sprocket wheel |4| fixed on a shaft |42. The shaft 42 isvrotatably mounted in bearing blocks |43 suitably secured, as by bolts |44, to the upper surfaces of the lower

conveyor support members

34 and 35.

It will be observed in Figures 3, 4 and 6 that the shaft |42 also has a sprocket wheel |46 fixed thereon, the lower portion of which is engaged by the upper reach of a sprocket chain |41 (Figure 5). The upper portion of the sprocket chain |41 is mounted on a sprocket wheel '|50 rotatably mounted on a stub shaft |5| xedly mounted in a block |52 suitably secured to the rear surface of the vertically disposed side frame member |6. The sprocket chain extends downwardly and rearwardly in Figure 5 and is also mounted on a sprocket wheel |54 fixed on the shaft 10 extending from the speed reducer 1| heretofore described.

Itis thus seen that the electric motor drives the speed reducer 1| which in turn transmits rotation to the output shaft and this shaft 10, in turn, causes the upper reaches of the lower conveyor to move from right to left in Figure 1 or from left to right in Figure 5 and causes the lower reaches of the upper sprocket chains |2| and |22 to also move in the same direction in synchronization with the

lower conveyor chains

43 and 44.

The upper conveyor frame members |30 and 3| are pivotally supported at their front ends on the shaft |34 and they are adjustable at their rear ends. There is provided an angle bar |51 which bridges and is welded to the upper surfaces of the upper conveyor support members |30 and |3| and extends substantially on each side of the same as is clearly shown in Figure 3. This member |51 has the upper ends of a pair of adjustment rods |58 and |59 suitably secured thereto, as lby welding, which extend downwardly and slidably penetrate the upper iianges of the corresponding lower

conveyor support members

34 and 35 and each of which has adjustment nuts |60 threadably mounted thereon and bearing against the upper and lower surfaces of the horizontal flanges of the

respective frame members

34 and 35 to thus permit adjustment of the upper conveyor support members |30 and |3| to vary the distance between the lower reaches of the upper conveyor chains |2| and |22 and the upper reaches of the

lowerconveyor chains

43 and 44 to permit packages of yarn of varying size to be compressed by this machine.

It will be observed in Figure 1 that the rear vertically disposed frame member 20 is graduated, as at |62, and a substantially L-shaped pointer |53 is adapted to move adjacent the graduations |62 with movement of the upper conveyorv support frame members |30 and |3| to serve as a guide or reference to the operator of the machine in determining the relative position of the rear portion of the conveyor chains |2|, |22 and 43. 44. 'The point |63 is suitably secured, as by welding, to the outer surface of the upper conveyor support member 30.

The upper conveyor support members |30 and |3| have a plurality of longitudinally spaced track frame members |65 and |66 depending therefrom and suitably secured thereto, as by welding, and to the lower ends of which a plurality of transverse track support'l members |61 are suitably secured as by welding. The track support frame members |61 extend transversely of the machine and support a pair of transversely spaced ltracks or trackways |10 and |1| against which the upper surfaces of the lower reaches of the upper conveyor chains |2| and |22, respectively, are adapted to move in sliding engagement therewith.

Upon movement of the conveyors 45 and |20 from right to left in Figure l, the cup-shaped members |23 will gradually engage the upper end of the package of yarn in the coinciding lower cup-shaped member |00 and will gradually exert an increasing pressure thereon until the opposed ends of the packages of yarn have been rolled toward each other at their outer edges substantially in the manner in which the package of yarn is shown at the extreme left-hand portion of Figure 1. Due to the fact that the upper and lower cup-shaped members |23 and |00, respectively, are not always disposed in axial alinement with each other as they cooperate in acting upon opposed ends of a package of yarn, theV cup-shaped members |00 and |23 will be caused to pivot upon their respective screws ||0 and ||0, this pivotal movement permitting the coinciding cup-shaped members 00 and |23 to substantially aline themselves with one another and the projections |04 thereon limiting the amount of pivotal movement which may occur due to the projections |04 engaging one or the other of the adjacent rollers |05 (Figure 2) on the corresponding conveyor chain. This pivotal movement is limited so as to prevent the dies |00 and |23 from swinging excessively as the axes thereof are disposed in a substantially horizontal plane, as would be the case adjacent the outer surfaces of the corresponding sprocket wheels on which the lower and upper respective conveyor chains |2|, |22 and 43, 44 are mounted.

It is evident that the packages which have been placed on the dies |00 will slide off of the pilot pins ||4 and ||4 as the dies |00 move to inverted position, in which position they are shown on the lower reaches of the

lower conveyor chains

43 and 44 in Figures 1 and 5.

It is thus seen that there is provided a machine for upsetting or breaking the outer portions of opposed ends of packages of yarn automatically comprising an upper and a lower conveyor, the lower conveyor projecting substantially beyond the upper conveyor so as to permit an operator to place packages of yarn on the dies provided therefor on the lower conveyor. -This results in all of the packages of yyarn which are of substantially the same length having opposed ends thereof upset uniformly so as to loosen the turns of yarn at opposed ends and at the outer edges of each package of yarn so that all of the yarn in each package of yarn maybe uniformly penetrated by the dyes, sizing solutions or other treating fluids to which the packages of yarn may be subsequently subjected. v y Various changes in the particular structure illustrated in the drawings can be made without departing from the `spirit o'f the invention or the scope of the accompanying claims. For example, the dies or cup-shaped members could bedisposed so as to move toward each other in a horizontal rather than a vertical plane.

In the drawings and specification there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims. i

A machine for upsetting opposed ends of tubular packages of yarn comprising a frame, a lower conveyor mounted in the frame comprising a pair of endless sprocket roller chains, driving means for imparting movement to the pair of sprocket roller chains, each of the sprocket roller chains having special links thereon spaced substantially from each other, a plurality of substantially cup-shaped dies pivotally connected to the special links and being disposed between the two chains, substantially triangular projections on the cup-shaped members having the pointed ends thereof extending between adjacent rollers on the roller chains and being adapted to engage adjacent rollers upon the corresponding cupshaped members being pivoted to limit pivotal movement thereof, each of the cup-shaped members having a substantially concave cavity in its outer surface relative to the roller chains and also having a pilot pin projecting outwardly from the center of said cavity and'onto which a tubular package of yarn is adapted to be placed, a second conveyor of identical construction to that of the rst conveyor. disposed substantially above the first conveyor and being of substantially less length than the first conveyor, said second conveyor also including a pair of transversely spaced /conveyor chains and also having a plurality of substantially cup-shaped members supported thereby, means for driving the second conveyor in synchronization with the first conveyor, the first and second conveyors being disposed in converging relation to each other in the direction of travel of the conveyors, means for adjusting the displacement between the conveyors at the ends thereof towards which the conveyors are driven whereby, an operator may place a package of yarn in each of the cup-shaped members on the lower conveyor in advance of the cup-shaped members moving beneath the upper conveyor and wherebythe cup-shaped members on the upper conveyor will engage the upper ends of the packages of yarn carried by the cup-shaped members on the lower conveyor and, due to the convergence of the conveyors, a gradual pressure will l2 be applied to opposed ends of the packages of yarn to thus roll the turns of yarn at the outer edges of each package of yarn over one another to thus upset the ends of the packages of yarn chains having special links thereon spaced substantially from each other, a plurality of substantially cup-shaped dies pivotally connected to the special links and being disposed between the two chains, substantially triangular projections on the cup-shaped members having the pointed ends thereof extending between adjacent rollers on the roller chains and being adapted to engage adjacent rollers upon the corresponding cupshaped members being pivoted to limit pivotal movement thereof, each of the cup-shaped members having a substantially concave cavity in its outer surface relative to the roller chains and also having a pilot pin projecting outwardly from the center of said cavity and onto which a tubular package of yarn is adapted to be placed, a second conveyor of identical construction .to that of the rst conveyor disposed substantially above the first conveyor and being of substantially less length than .the rst conveyor, said second ccnveyor also including a pair of transversely spaced conveyor chains and also having a plurality of substantially cup-shaped members supported thereby, means for driving the conveyors, the first and second conveyors being disposed in converging relation to each other in the direction of travel of the conveyors whereby, an operator may place a package of yarn in each of the cupshaped members on the lower conveyor in advance of the cup-shaped members moving beneath the upper conveyor and whereby the cupshaped members on the upper conveyor will engage the upper ends of .the packages of yarn carried by the cup-shaped members on the lower conveyor and, due to the convergence of the conveyors, a gradual pressure will be applied to opposed ends of the packages of yarn to thus roll the turns of yarn at the outer edges of each package of yarn over one another to thus upset the ends of the packages of yarn aut/omatieally.

8. A machine for upsetting opposed ends of 'tubular packages of yarn comprising a frame, a lower conveyor mounted in the frame comprising a pair of endless sprocket roller chains, driving means for imparting movement to the pair of sprocket roller chains, each of the sprocket roller chains having special links thereon spaced substantially from each other, a plurality of substantially cup-shaped dies pivotally connected to the special links and being disposed between the two chains, substantially triangular projections on the cup-shaped members having the pointed ends thereof extending between adjacent rollers on the roller chains and being adapted to engage adjacent rollers upon the corresponding cupshaped members being pivoted to limit pivotal movement thereof, each of the cup-shaped members having a substantially concave cavity in its outer surface relative to the roller chains and also having a pilot pin projecting outwardly from the center of said cavity and onto which a tubu- 13 lar package of yarn is adaptedto be placed, a second conveyor of identical construction to that of the iirst conveyor disposed substantially above the' first conveyor and being of substantially less length than the first conveyor, said second conveyor also including a pair of transversely spaced conveyor chains and also having a plurality of substantially lcup-shaped members supported thereby, each of said dies in the upper conveyor also having a pilot pin projecting from the center thereof terminating substantially short of the cuter edge of the dye and which is adapted to enter the tubular lpackage of yarn as each package of yarn passes into engagement with the coinciding cup-shaped member on the second conveyor, means for driving the second conveyor -in synchronization with the :drst conveyor, the

first and second conveyors being disposed in converging relation to each other in the direction of travel of the conveyors, means for adjusting the displacement between the `conveyors at the ends thereof towards which the conveyors are driven whereby, an operator may 'place a package of yarn in each of the cup-shaped members on the lower conveyor in advance of the cup-shaped members moving beneath the upper conveyor and whereby the cup-shaped members on the upper conveyor will engage the upper ends of the packages of yarn carried by the cup-shaped members on the lower conveyor and, due to the convergence of the conveyors, a gradual pressure will be applied to'opposed'ends of the packages of yarn to thus roll the turns of yarn at the outer edges of each package of yarn over one another to thus upset the ends of the packages of yarn automatically.

on the cup-shaped members having the pointed ends thereof extending between adjacent rollers on the roller chains and being adapted to engage adjacent rollers upon the corresponding cupshaped members being pivoted to limit pivotal movement thereof, each of the cup-shaped members having a, substantially concave cavity in its outer surface relative to the roher chains and also having a pilot pin projecting outwardly from the center of said cavity and onto which atubular package of yarn is adapted to be placed, a second conveyor of identical construction to that of the first conveyor disposed substantially above the first conveyor and being of substantially less length than the first conveyor, said second conveyor also including a pair of transversely spaced conveyor chains' and also having' a, plurality of substantially cup-shaped members supported thereby, each of said dies in the upper conveyor also having a pilot pin projecting from the center thereof terminating substantially short ofthe outer edge of the dye and which is adapted to -enter the tubular package of yarn .as each pack-f age of yarn passes into engagement with the coinciding cup-shaped member on the second conveyor, means for driving theseond conveyor in synchronization with the first conveyor, .the

first and second conveyors being disposed in converging relation to each other in the direction of travel of the conveyors, means for adjusting the displacement between the conveyors at the ends thereof towards which the conveyors are driven whereby, an operator may place a package of yarn in each of the cup-shaped members on the lower conveyor in advance of the cup-shaped members moving beneath the upper conveyor and whereby the cup-shaped members on the upper conveyor will engage the upper ends of the packages of yarn carried by 'the cup-shaped members on the lower conveyor and,due to the convergence of the conveyors, a gradual pressure will be applied to opposed ends of the packages of yarn to thus roll the turns of yarn 'at the outer edges of each package of yarn over one another to thus upset the ends of the packages of yam automatically and said cup-shaped members on the lower conveyor being inverted after the yarn package thereon has been compressedto permit the package to fall free thereof.
