BA LL-WINDING MACHINE.

To all whom it may concern.'

and useful Improvements in allVinding Machines. of which the following is a specification.

vMy invention relates to an improvement in machines/tor winding balls, and is particularly directed 'to machines for winding golt' balls. an object oi' the Vinvention being the provision ot' a machine capable of winding goltl balls having a sott center.

1n my prior Patent No. 1,242,885 of October 9. 1917, I have shown a machine for winding golf balls having a sott center, but

in that imaufhine it isv necessary to start the winding operation by hand winding the elastic 'tape upon the center or core until it has been wound suiiiciently' to enable the ball to be placed in the machine without distorting the core.

The machine. of this application is constructed in such. a manner that a ball may be wound therein 'from the outset, means having been provided for so regulating they tension on the tape.y etc.,that all danger o y distortion of the center or core is eliminated.

In the accompanying drawings, wherein I have illustrated an embodiment'of my invention,

Specification of Letters Patent.

v 'which is mounted a pinion 22.

tram in one housing 19 is a duplicate of Patented July 25, 1922.

Application filed January 6, 1921. Serial No. 435,430.`

designatesthe bed of the machine on which are disposed vertically-extending supports 2 in which is mounted a drive shaft 3. The leftha'nd end of this shaft as viewed in Fig. 2 carries a broadtaced gear 1 and driving pulley 5, power being supplied to the latter from any suitable source.

On the other end of the'drive shaft I i mount a beveled gear 6 meshing with a beveled gear 7 mounted on a vertically-extending shaft 8, the latter carrying also a pair of cams 9 and 1() and a pinion 11.

Above the drive shaft 3 is mounted a pair ot' parallel Vrollers 12 adapted to be moved longitudinally relatively to each other by the cams 9 and 10 already referred to.- These rollers are rotatedl in the same direction and simultaneously by gears 13 meshing with the broad-faced gear l already referred to.

The shafts on whichthe rollers 12 are mounted are operatively connected to slides 14, one for each'shaft` these slides carrying rollers 15 and 16 adapted to be engaged by the cams 9 and'l() respectively. The cams are set relatively to each other so that as they are rotated they cause the rollers 12 to alternately move to the left as viewed in Fig. 2, the rollers being moved in the the opposite direction by springs 17.

Immediately above the rollers 12 are mounted two beveled rotatable bodily movable pressing rolls 18 adapted to engage the ball or core being wound and tonot only hold the same in contant with the rollers 12 but to impart motion to theball or core.

The rolls 18 are mounted in housings 19 and are driven through gearing shown best in Figs. 3 and 4 and which will now be described. The rolls are mounted on short shafts 20 and 21 respectively, on each of As the gear that in the other, one only will be described. The pinion 22 meshes with a gear 23 mounted in the housing 19, this gear meshing with a floating gear 24 carried by a triangular-shaped plat-e 25 mounted on a shaft 26 passing through both housings 19. This shaft carries a gear 27 meshing with the gear 24 and a gear 28 meshing with a gear 29 mountedon the shaft 30 and which sha'tt carries a large gear 31 meshing with the broadfaced gear 4. As the shaft 26 passes through both housings 19 it .will be apparent yball or core during the winding operation it is desirable that the rollers 18 be rotated at Adifferent rates of speed. To: this end I pro Vide the plates 2,5 and gears 24 already referred tfo. The plates 25 are pivotally mounted on the shaft 26 and each-carries a roller 32 urged into contact withjthepface of cams 33 by springs 34. The cams 33 are so set that a depression .in one-cam is opposite to a raised portion in the companion cam. It will be apparent that withthe gear train in motion whenv a. roller`32 is engaged by a raised `portion on a cam 33, the plate 25 will be rocked about its pivot to carry with it its gear 24. This bodily movement of the gear 24 will accelerate the gear 23 and thereby accelerate the correspondingpressing roller 18. At the same instant a depression in the other cam 33 will be engaging the other roller 32, so that its pressing'roll will be given a corresponding negative acceleration.

The housings 19 are pivoted onthe shaft 26 so that they may be raised to `permita finished ball to be removed or a new core inserted. The raising or lowering of the hous` ing is accomplished by a foot pedal 36 conl nected by a suitable link 37 to an upright 38 attached to the housings. The pressure of the rolls upon the ball is readily adjusted by the adjusting member 39.

The mechanism so far described has to do only with the apparatus for -handling the ball or core dur-ing the Winding operation.

tape 43 with which the ball or coreie wound passing from a supply roll over a fixed trough-shaped guide 44, over guide roller 40,

Iunder guide roller 41v over guide roller 42 to the ball or core 45. The roller or drum 40 is provided with a brake-band'46,` the tension of which is adjustable by the adjustingmechanism 47. The roller 41 is rotatively supported on a stud shaft 48 carrying differential gearing comprising an externallytoothed gear 49 meshing withaypinion 5() mounted on a stud shaft 51 to which the guide roller 42 is secured; Keyed 'tothe gear 49 is Ia small'gear 52 also rotatively supported on the stud shaft 48, this gear meshingJ with a pair of floating gears 53 conf nected to each other by a member 54 which is keyed to the. roller 41, theseA gears in turn meshing with an internallyftoothed gear 55. The latter is provided with a later-al flange 56,-adaptedto be engaged by a clamp plate 57. The latter is suitably mounted in the Ahousing 58,-enclosing the ldifferential gearing. upon a stud shaft 59 which is moved to the right as viewed in Fig. 7 by a cam 60. The latter. isgiven a partial rotation at the desired instant through a connection 61 and 62with aj'cam 63 driven by a gear 64-meshing with a pinion 11 already referred .-to. The roller 41 has operatively attached to it the tension regulating device shown in Fig. 9.

becurd to: the geul" 49H and extending i Y' laterally'with respect tothe roller 41 is a drum 65, this drum being secured to the gear- 49 by screws 66. Cooperating with and pari4 tially surrounding this drum 65 'is a brake band 67, one end being secured at 68 while the other end 'is iexibly secured at 69 to one arm of a bell-crank lever 70 carrying at one end an adjusting screw 71. adapted to' bear upon the surface of the housing 58 whereby eov the tension ofthe brake hand 67 on the drum i 65 may be adjusted. i

In operation a turn of tape is taken around'. a core 45 and the core then insertedin the machine upon the longitudinal movable rollers 12, the pressing rolls 18-being moved upwardly by depressing the foot pedal 36. If the machine 4is now set in operation the rollers 12 will be driven and also be moved longitudinally relative to each other, and4v the 'pressing rolls. 18 -will be rotated attheA same timeat different variable'speeds. vThe core due to these movements of the rollers 12 and the pressing rollers 18 will be rotated about a horizontal and a vertical axis, the

peripheral speed of rotation of the core about the horizontal axis being practically uniform while'the motion of the core about the vertical'axis is irregular, varying in both speed and direction drie tothe shape of the cams 9 and 10 and the cams 3 3, resulting in a practically uniform distribution of the tape on the core and the production of asubstantially spherical ball.

At the start of the winding operation the i cam 63visvi'ny position to cause the link 'llto actuate the cam 57 into engagement with the flange 56 of the internal toothed gear toretard the same. device illustrated in Fig. 9 operates to retard the rotation of the roller 41- to thereby retard the rotation of the roller 42. The result of this retarded' motion of the roller 42 is to -cause the tape 43 to be placed under tension and owing to the curvature of the. roller 42 which roller is preferably kmade of aluminum the tape will bestretched laterally so as not to deform the core. l

It will beapparent that the core is driven aboutboth a* horizontal and a vertical axis At this time also the tension from four points, `to-wit; the two points of contact .of the rollers 12 with the core and within the purview of my invention.
