BALL-WINDING MACHINE John R. Gammeter, Akron, Ohio Application March 17, 1945, Serial No. 583,215

This invention relates to machines for applying thread rubber, cord or other continuous flexible material, and in particular relates to ball winding machines.

An object of the invention is to provide improved means in a ball or like winding machine, whereby when the flexible material being wound onto a ball or core is broken, or when the normal continuity of the material is otherwise interrupted, operation of the'machine will be automatically stopped to prevent snarling of the material.

Another object of the invention is to provide a ball-winding machine having improved means for automatically stopping operation of the'machine when a ball thereon has been wound to predetermined size.

Other objects of the invention Will be manifest from the following brief description and the accompanying drawings.

Referring particularly to Figures 1 and 2, there is shown a golf-ball winding machine of conventional type, similar to the machine disclosed in applicants prior Patent No. 647,256, issued April 10, 1900, with reference to the principle utilized for winding thread rubber onto a ball core. According to this winding principle a ball core C is yieldingly retained between two pairs of spaced rollers l0, l and II, II rotatably mounted in spaced holder members I 2 and IS, the pairs of rollers being arranged with the respective axes thereof in vertical planes parallel to a vertical 21 Claims. (Cl. 242-3) winding plane through the center of core C, and the holder members being carried by supports l4 and I mounted as shown to be simultaneously and uniformly separable against the yieldingaction of springs l6, Hi, to permit growth of core 0 as thread rubber R, for example, is wound there-- on by a rotating Winder or material feed mechanism, indicated generally at W. Intermittent gear mechanisms, indicated generally at ll, are

provided in casings Ha, Ila for rotating the rollers in various directions, whereby a compound rolling action is imparted to the ball which will result in constantly changing great circles of the core C being presented to said winding plane. This compound rolling action of the core C with respect to the winding plan results in uniformly spherical growth of the'winding.

For the purpose of the present invention gearing in casings I1 is driven by a shaft l8, which in turn is adapted to be driven by a belt l9 shiftable from an idler pulley 20 on said shaft to a driver pulley 2| keyed thereon. To this end, the belt I9 is manually shiftable at will between pulleys 20 and 2!, by means of a belt-shifting yoke 23 pivoted at 23a intermediate the ends of an elongated lever 24, which is pivoted at one end thereof to a top supporting plate 25 of the machine, as indicated at 26; The other end of lever 24 extends freely forwardly; .of the machine to provide an operating handle therefor.

The lever 24 is normally yieldingly retained in the inoperative position thereof shown in Figure 2. For this purpose a bar 21 is pivotally connected at one end to lever 24 at 23a and extends laterally on the under-side of plate 25, the other end of the bar having thereon .an ofi-set lug 28 to which a rod 29 is connected to be slidably received through a recess in a bracket 30, secured to said plate, so that a-compression spring 3| received on rod 29, between the bracket and said lug, will tend to urge bar 21 to the left (Figure 2) as limited by engagement of an adjustable stop 7 nut 300. on the end of rod 29 against bracket 25a.

The lever 24 may be releasably retained in an operative position thereof, in Which belt [9 drives pulley 2!, as previously described, by means of an electrically operated latch mechanism 33 of known type, secured to the under-side of top plate 25. Accordingly, there is provided a hooked portion 34 on the end of bar 21, adjacent rod 29, adapted to engage over a shiftable catch 33a of the latch mechanism, when lever 24 is urged to the right against spring 3| (Figure 2), thereby to maintain the machine in operation until the mechani m is again released. The latch mechanism may be releasable at will by an operator momentarily pressing a button 34a to close an electrical circuit, to withdraw catch 33a, and thereby permit spring 3! to urge lever 24 to the left and stop the machine. Said electrical circuit is indicated in the wiring diagram in Figure 9 by lines 35 and 3% connecting lines L1 and Lcfrom a suitable source of electrical sup-ply. Other electrical connections to. this latching device will be described later.

The winder or rotatable feed mechanism W, for applying the material R to a core C is primarily a ring 38 which is mounted to rotate about an annular track member 39 fixedly supported on top plate 25. The track 39 comprises an inner bearing ring 390, and a radially outwardly extending annular flange 39b threaded thereon, and is arranged so that the ring 38 will rotate concentrically around a core C in holders l2'andl3. Ring 28 is adapted to be rotated by meshing engagement of external gear teeth 39 thereon with a gear ll, which is driven, through bevel gears alt- 32, by the shaft l8 being driven as previously described. That. is, the rollers it and ll of the holder members, and the winder ring 38 are operated as described, simultaneously, by shaft i3 being driven through manual operation of lever 2= lto the right toshift yoke 23 to move belt ill from idler pulley 29 onto drver pulley 2 1.

Upon operation of releasing mechanism 33 to stop the machine as set forth above, it is desirable that ring 38 will not continue rotating due to 'momentum thereof, as such continued rotation would minimize efiectiveness of safety automatic control means to be described later. To this end a brake 35 is pivotally connected at 26 to the machine frame to be. yiel'dingly urged, by a tension spring 46a, into frictional engagement with pulley 2! when lever 213 is released to inoperative position. A suitable cam ll on bar 21 is adapted to engage an upwardly projecting flange 58 on the brake to release the same, against the action of spring- 46a, when lever 24 is operated to start the machine (see Figure 2a). By means of a handle as the brake iis releasable to permu; rotation ofthe winder W for operational adjustment or setting purposes.

Referring particularly to Figures 5 to 8, there is shown a reel-supporting bracket 5'! which is secured to ring 33 to rotate therewith. This bracket is provided with spaced lugs 52 and 53 which are apertured to receive a removable pin 5'4, may be locked against relative rotation in said apertures by means of a spring-pressed d'etent 55 insertable, from one side of the bracket, for rotatably receiving thereon a spool or reel 56 of thread-rubber or similar flexible material R. Adjustable tension means is proveded at 5-! by which yielding pressure is applied through a tension member 58 yieldingly to engage one end of reel 56.

Indicated generally at 69 is guide means for directing the continuous thread rubber R from reel 55. to the. ball-winding plane, previously referred to, this guide means being carried by ro- 7 tatable winder ring 38. In guide means 60 there is provided a rod 61, supported between lugs 52 and 53 of bracket 5!, around which the thread rubber from reel 56 may be guided to clear the inner periphery of track 3'5! and to extend rear- B Z-the" thread rubber is trained to extend for- The pin is quickly removable and wardly of the machine to engage around a concave roller 6:: mounted on said bracket extension 54, the material then being guided rearwardly and radially inwardly in said winding plane by means of a roller 66, also secured to said extension 5%. A guide needle 81, of known type, is pivoted at 58 to bracket extension 64 with a bifurcated or slotted free end thereof extending to be relatively close to a ball or core C retained between the holder members I2 and i3, so that the material R passed through said bifurcated end will be maintained in said winding plane. This arrange ment is such that when the machine is operated as. previously described, to rotate the ring 38 simultaneously with operation of said holder members to impart compound rolling movement to core C, the thread material will be wound on the core in constantly changing great circles. The tension of the material R, as applied to the ball or core 0, is adjusted by means of the adjusting device 5-? (see Figure 7).

Should the material R for any reason become broken, means is provided for automatically stopping the machine so that the fault can be corrected. To this end, pivotally mounted at 10 on the extension 64 of bracket 5i may be an arm H, of electro-co-nductive material, which is adapted to extend substantially in the direction of a chord of the inner periphery of an annular track me'mebr 39a and to engage under the two of the reaches formed by the material R extending rearwardly and forwardly in a loop about roller 62-. Thus in norma1 operation of the machine one or both of said reach-es of material R engaging arm "H will prevent radially outward swinging movement thereof, due to centrifugal force, when the ring 38 is rotated. The arm H may have an. extension ll-a on the side of pivot 19 opposti'e. thereto, to act as a counter-balance for efiicient operation. Fixedly secured on electrical insulators 'sZ-on fixed track member 391) may be a contact ring 73 of electro-conductive material, said ring being arranged concentric with ring 38 and with its inner edge in line with arm H (see. Figure 5), whereby upon release of the; arm H by "disengagement. with the material R, as described (see Figures 5 and 6) the arm will be swung radially outwardly by centrifugal force as the. winder ring 3-8 is rotated, to make an electrical connection with contact ring 13. For the latter purpose the arm H and ring 73 may be connected in an electrical circuit, in parallel with the previously described circuit through switch button 34, to the releasable latch 33 (see Figure 9). Accordingly the arm I! is connected through line T5 to power line L2, and ring i3 is connected by line 16 through latching device 33 to power line L1, to complete the circuit. Thus if the material R is broken during the operation of the machine for winding a ball, arm ll upon engaging ring 13 will close the circuit through lines 15 and "i6- and latching device 33, thereby releasing, bar 21 which is yieldingly urged by spring 31 to move lever M to its previously described inoperative position.

As only a, momentary contact between arm H and ring 13 is required to release bar 21, means is provided to. open the last described electrical circuit when the machine is stopped. To accompush this, a spring-pressed switch Tl may be provided to have an operating pin 18 thereon en- 'g'ageab'le by lever 24. when it moves into said inoperative position, thereby to maintain switch H in open condition when the machine is not in operation (see. Figures. 2 and 9).. Conversely,

the center of said core.

rotation of ring 38 about track 39a. --movement of ring 38, carrying the feed or winder when lever 24 is operated to start the machine switch I! will close to set the circuit through lines and 16 in condition for subsequent use as previously described when the thread material again becomes broken. I I

Means may also be provided automatically to stop the machine when a ball wound therein has grown to predetermined spherical size. This is accomplished by provision of an arm 13 (see Figure 2) extending from one holder support I4, at the side of the center line of the machine opposite to a pivotal point Ma of the support. Yieldingly and adjustably mounted on top plate may be a switch 8| having an operating pin 82 which is engageable by said arm 19 upon the ball growing to'said predetermined size, thereby to close an electrical circuit (see Figure 9), through a line 83 connecting power line L2, and aline 84 connecting power 11116 111 through the releasable latching device 33. The last named circuit is connected through latching device 33 inparallelism with the two previously described circuits therethrough. To obviate maintaining a closed circuit through line 83and 84 when the machine is not in operation, a spring-pressed switch 85 has an operating pin 36 engageable by lever 24 upon latching device 33 being released, in the manner previously described with refer- 'ence to switch 11.

For operation of the machine for winding golf balls, for example, continuous thread rubber or like continuous flexible material is first fed from reel 56 around guide rod 6|, around rollers 62 and 65 to form a loop having closely adjacent reaches extending rearwardly and forwardly through track member 39a, and from roller 65 the material is guided around the roller 66, and through the slot of needle 61 and onto a core C of known type, said material thereby being guided to the core in a winding plane which extends through The free end of the material is passed around the core C several times to secure it thereto prior to operation of the machine.

Next, the operator manually urges lever 24 to the right, as viewed in Figure 2, to engage hooked extension 34 of bar 2'! with catch 33a of the elec- .trical latching device 33. The catch 33a will retain lever 24 in the operative position until latching device 33 is subsequently actuated to release hook 34 through the action compression spring 3!. This operation of lever 24, through yoke 23, will move the belt l9 from the idler pulley 20 to driven pulley 2| and shaft I8, thereby to cause compound rolling "movement of core C held between the holder members simultaneously with The rotary mechanism W and guide means 60 therewith, is effective to wind the thread material R under desired tension in constantly changing great circles about core C to desired uniform wall thickness, as previously described. Should it be desirable .for any reason to stop the machine, as for exam ple, for the purpose of making adjustments, the operator may do so by pressing button 34a (Figures 2 and 9) to release latching device 33 to stop the machine. The machine will similarly be stopped, automatically, upon the ball being wound to desired size causing operation of holders l2 and I3 to move the arm 19 to predetermined position to release the latching device 33 through operation of switch 8|.

Should normal operation of the machine be interrupted by a break in the material R, or by substantialslackening of the same, the arm .II will be released tocontact the lring 'l3 in any position of rotation of winder ring 38, which will close the wiring circuit through lines 15 and 16 to operate latching device 33, and thereby automatically stop the machine. a Thus has been provided an improved ball or like winding machine having means incorporated therein whereby it will be automatically stopped immediately either upon the ball having grown to predetermined size, or upon an interruption in the continuous feeding of the thread material to the core C. Obviously, the machine is adapted to be used for winding or applying materials other than thread rubber, such as cord, steel wire, steel tape, fibre glass or other continuous flexible material. Also, the invention is not limited to use for winding golf-balls but may be utilized for'winding the materials mentioned to form or reinforce other articles, such as baseballs, hollow athletic balls, tubular articles, etc.

It will be understood from certain characteristics of golf balls, pertaining particularly to standard diameters, weights, balance, resiliency upon impact with a golf club head, etc., that golf ball manufacturing procedures must necessarily be exacting to provide uniformity in production. This uniformity, of course, is materially affected by any deviation from feeding the thread material through the machine under requisite normal tension. The expression interruption in the normal continuous winding of said material, for example, as contemplatedin the claims, therefore, presupposes any condition which will interrupt the continuous normal feeding of the thread material to the ball' being wound in the machine, such as a break in the material, or a slackening thereof, or exhaustion of the supply of material.

Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.
