corporation of Delaware Application March 23, 1950, Serial No. 151,475 10 Claims. (01. 24246.2)

This invention relates to a tube holder or arbor for supporting the packages of strand wound about an annular core, particularly to a rotatable support upon which the package may be secured and centered with respect to its axis of rotation.

It is an object of the invention to provide a holder having a rigid spindle structure such that the rotatable portion may revolve freely without vibration. It is another object to provide a holder on which the package may be centered and secured to a position wherein it is restrained from moving or tilting relative to the holder. It is still another object to provide a package arbor which has a spindle or shaft of unitary construction. Other objects, features and advantages of the invention will be apparent from the description of the invention relating thereto in which:

Fig. 1 is a. longitudinal section taken along the axis of apparatus according to one embodiment of the invention;

Fig. 2 is an end view of the apparatus illustrated in Fig. 1;

Fig. 3 is a section view taken along line III-III of Fig. 1;

Fig. 4 illustrates a spring member of Fig. 1 viewed from another direction;

Fig. 5 is a section view along the axis of a modifled apparatus;

Fig. 6 is a section view taken along line VI--VI of Fig. 5;

Fig. 7 is an end view of a manual control element of the apparatus of Fig. 5

Fig. 8 is a longitudinal section of modified apparatus taken along its axis; and

Fig. 9 is an end view of the apparatus illustrated by Fig. 8.

In brief, an arbor or rotatable package support according to the invention comprises a unitary spindle, an annular rotary housing supported on the spindle by bearings, spring mounted gripping members for engaging the inner surface of an annular strand package to the outer wall of the housing, and a cam controller for engaging surfaces of the springs to urge the gripping members into engagement or' out of engagement with the package, and. a portion of the controller extending axially from one end of the housing to make it accessible for manual manipulation.

Fig. 1 illustrates in section an assembly which may be readily mounted on a twister or other winding device by insertion of the left end of a spindle [2 into a cylindrical socket (not shown) slotted to accommodate a pin l4. A cylindrical sleeve or housing I5 is supported rotatably with respect to the shaft by anti-friction bearings ll and N3 the inner races of which are secured to the spindle by set screws l9 and 20. Annular spacer or hub members 24 and 25 center and support the housing [5 on the outer races of the bearings. Three leaf-type spring members 28 are secured by rivets 29 to extend lengthwise of the sleeve to sections of the inner surface of the sleeve I5 apart. Fig. 4 illustrates a spring member 28 as seen when viewing the member in a radially outward direction from the axis of the assembly. The springs 28 have apertures 39 in which to secure blocks 32 comprising material such as a soft vulcanized rubber composition. The blocks 32 are each supported along a radius extending from the axis of the shaft l2 through holes 33 provided through arcuately spaced sections of the housing 15 to engage the inner surface of a rigid core 3 1 of a strand package. The end portions which support the blocks 32 deflect radially outwardly to urge the blocks against the core surface. Thus, a package 35 is supported by the assembly on the blocks 32 and on the surface of a flared flange 38.

To release the grip of the blocks 32 on the package core 34, a cam member 36 best illustrated in Fig. 3, may be moved in an axial direction within the housing to produce deflection of the springs. Sections 31 of the springs are biased in a radial outward direction toward the left as viewed in Fig. l to produce cam surfaces on which the member 36 may work. Movement of the cam member 36 to the right causes the peripheries of apertures 46 of the member to slidably engage the outer surface of the springs whereby the blocks are carried radially inwardly and away from the core surface. The cam member is connected by three parallel rods 39 to a manual control member 40 spaced axially from the cam member and the outer surface of the bearing 25. The control member is provided with a sleeve element or handle 42 having an outer knurled surface with which to grip the member 40. Thus by manual manipulation of the member 42, the position of the cam member 36 may be varied in a direction lengthwise of the springs 28 to obtain radial movement of the blocks 32. The sections 31 of the springs are provided with surfaces 44 which are substantially parallel to the cylindrical wall of the sleeve l5 so that the cam member 36, when pulled into the position for producing disengagement of the blocks, will remain in that position until forcibly moved toward the right as viewed in Fig. 1.

Fig. 5 illustrates a modification of the device shown in Figs. 1 to 4 wherein a sleeve or shroud ia is suported on the shaft l2 in the manner shown for the sleeve l5 of Fig. 1 except that the left bearing Fla is spaced further inward from the left end of the sleeve I5a. A spacer member which supports the sleeve on the outer race of the bearing Fla is apertured to permit extension therethrough of two leaf-type springs-5U. As viewed in Fig. 5, the left ends 51 of the springs engage the inner surface of the sleeve 15a; the springs are set or formed, and the apertures 48 of the spacer member are positionedatsufiicient radius, so as to deflect the portions of the springs extending to the right from the apertures toward the inner surface of the sleeve. 1 Thus the springs are strongly inclined to urge the resilient cushions 53 fastened thereto in a direction radially outwardly to a position wherein they extend through apertures 54 through the sleeve l5a against the inner surface of a strand package (not shownysurroundin .the sleeve [5a. The right end portions of the springs are; contoured to provide cam surfaces 56 bywhich the, springs mayb en a y a am m m er. .55 andde: flected towardtheshaft l2 to carryjhe cushions 53 out of engagementv with the inner surf-aceof a tran ack h a m m 5 .1mm: r ly er res, as sho n fiet awgm: l": e ha l2. an tqp vide cams r aqe 51. The member 55 maybe moved in a direction parallel to the shaft toward and away frpm:.-th e inner bearing race 58. The cam. member 55 is connected to a handle, also illustrated in Fig. 7, m ri ad eele en 5. n atu ular- $1. m n by w c r d !di betwe n and secured to thecamvmember and the element 66. The hub member 62 is apertured-to permit extension therethrough and movement relative thereto of the rods 64. p H Fig. 8 illustrates a strandpackageholder in which engagementand disengagement of a pin rality or cushions 10 with the inner surface are strand package surrounding the sleeve [51) is .effected bya rotatable cam member 12 instead (if by axially slidab'le cam members such as employed in the embodiments described earlier here: in. The sleeve l5. is sup orted ontwoantif riction bearings 15 andllfij Ari annular hfnb 18 which supports and centers the left end poi; tion of thefsleeve 15b on the uter race or the bearing 15 is provided also with aflang'e 1.9 to re: ceive the edge of a package core to positively position the package in an axial direction with respect to the arbor. T he cushions 10 are each supported by leaf-type springs H which are secured to the sleeve by the rivets 13. The springs extend almost to the ri ht end of the sleeve [52; as viewed in Fig. 8. The outer diameter of the cam member 12 is slightly less than that of the inner surface of the sleeve member so as to be freely rotatable within the sleeve member; an aperture 8| through the member prevents contact thereof with the shaft l2. Handles 83 extending from the cam member enable manual rotation thereof with respect to the sleeve I51) and the end portions of the springs. As shown in Fig. 9, the cam is in the position permitting maximum outward deflection of the springs H and engagement of the cushions 75 with the inner surface of a strand package when supported by the arbor.

The cam member 12 is rotated from this position in a counterclockwise direction to bring the surfaces 85 into engagement with the outer surfaces of the springs "II. when desiredto move the cushions l0 radially inward torelease a package.

While preferred embodiments of the invention have been shown and described, it is to be under- 4 stood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
