Patented Nov. 12, 19 29 JAMES JONATHAN CALDWELL, OF CHICKAIVIAUGA, GEORGIA, ASSIGNOR TO STANDARD- COOSA-THATCHER COMPANY, OF CHATTANOOGA, TENNESSEE, A CORPORATION BALLING MACHINE Application filed June 30,

This invention relates to balling machines.

It is an object of the invention to provide an improvement over machines of this char.- acter in devices for moving the thread longibudinally along the ball, and particularly an improvement of the cam which operates the thread moving means.

A further object is to provide an improvement in balling machines whereby the machine may be operated at a much greater speed than machines heretofore known.

In machines of this character it has been customary to provide a double screw for moving a lever for carrying the thread along the ball of the machine. Such double screws as have heretofore been used have proved unsatisfactory in that the groove on the screw would'not always reverse the lead properly with a result that the machine would be stalled. I overcome this difficulty by'providing a groove around a roller and this provides a cam track for a cam follower which moves the thread shifting lever. This groove lies in a plane oblique with respect to the axis ofrotation of the shaft upon which the roller is mounted. This provides a positive cam track which cannot fail to function properly during operation of the machine.

The maximum speed possible on'the old style baller was 100 yards per minute, and the usual operating speed was approximately 65 yards per minute. The maximum speed on my machine is 500 yards per minute and it is being operated at a speed of approximately 200 yards per minute. This machine therefore has greatly increased production over the former machines.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a plan view of a balling machine showing my invention,

Figure A, a detail view of the cam follower,

Figure 5, a detail view showing means for adjustably securing the pivot point of the 1928. Serial No. 289,433.

Figure 6, a detail of the bracket carrying the thread trumpets.

In the drawings numeral 10 indicates the base of the balling machine having on each side a forward bracket 11 for supporting the drum on which the yarn is wound and the associated elements and rear standards 12. Inthe standards on the rear'of the machine a shaft 13 is mounted. This shaft carries a cam which is composed of two wheels 14 and 15 mounted upon a hub 16 on the shaft 13.

- The elements 14 and 15 may preferably be two wheels mounted obliquely with respect to the axis of the shaft 13 and spaced apart so as to provide a cam groove or track.

Secured at their ends on the base of the machine are two rods or shafts 17 and 18. These rods provide a track for a sliding cam follower 19. This follower comprises a sleeve 20 adapted to slide longitudinally along the rod 17. The sleeve has an arm 21 upon which a roller 22 is mounted. The outer end of the arm 21 hasa U-shaped notch 23 therein for sliding engagement with the rod 18. The cam follower 19 has a lug 24 with a depending pin 25 for pivotally securing upon the lug a lever arm 26 to be further described.

The shaft 13 and the cam mounted thereon are rotated by means of a chain 27 connecting pinion 28 and a large pinion 29 on the outer end of the shaft 13. Mounted upon the shafts 30 and 31 on the forward part of the machine are rollers 32 and 33. A gear 34 on the shaft 31 drives the shaft 30 by means of a gear 35 on the outer end of the latter shaft and an intermediate driving gear 36. A gear 37 on the shaft 31 drives a gear 38 on a shaft 39. This latter shaft has mounted thereon the pinion 28 above mentioned. The shaft 31 is operatively connected to any suitable source of power and provides the main driving shaft for the machine. A roller 40 is loosely mounted to rest between the cylinders 32 and 33. This roller provides the base upon which the thread is wound and is rotated by frictionally engaging the rotating drums between the peripheries of which it is mounted. The drum 4:0 is mounted upon a shaft 41. This shaft has at each end a bracket 42 which has secured upon its upper end a bearing 43 in which is positioned a plunger 44. This plunger has on its lower end an arcuate bearing for engagement with the shaft 41. A spring 46 positioned between the bearing and the bearing 43 provides resilient means for holding the bearing 45 engagement with the "shaft 4 1.

The lower end of the bracket 42 has secured thereto a strap r 47 This strap extends around a cam 48and is secured thereto. The cam is mounted upon a shaft 49. The outer end of this shaft has a drum 50 mounted thereon. Pins 51 and 52 secured in the supporting standard 11 of the frame provide pivot points ifor brake bands 54 and 53 and a'leve'r 56. The lever 56 pivotally mounted upon the pin 52, has an adjustable "weight 57 on itsbu'ter e d, v it may be readily seen in Figii're-B, the Weight '57by means 'ofbra'ke :ands'54'and holds the drum 5Q under constant friction to prevent its rotation. I

' trumpetsupporting standard 58 is slidably mounted up'o'n shafts 5-9 and "tidseoured at their ends in the frame "of the machine. Thisfstandard comprises 'integral sleeve 61 adapted to f'slide on the sha'tt 59. This which is pitetanyfsecm-ed by pin '63 to the arm 26. On nppm end the standard '38 has asleeve 64'which slides upon the shaft 67. Intermediate the euter trumpets i a oeiitral trumpet 6 8.

"The operation of "the device is as follows: When wiriding a single ball, a threadis passed through the central tiu'mpet and the bar 'ZO is fs'eeured infthe position shown in ftil'l hires in F igure 1. The machine is then driven by"power app lied to the outer ehd of 'thefshatt 31. drums 32 and 33 are rotated and I fictional engagement with the thread earry ngfdrum"the latter is roftatedfthe dram being hfeldin frictional arr ngement wit "the peripheries of the -ems "by inane er the strap 47 an the earn 48 which ishelds'ufiiciently by the brake band 5'4fto prevent loose rotation. Drive through gears 37, 38, pi'iiieh 28, 'belt'27 dg try-29, the cam \vl1ee1sjl4'jand T5 are i-(itated. {Thecain followfer rol'ler 22 engaging between the peripheries "of "the oam wheels :14 and 15 is moved batik 1 and forth along "the shaft This swings "the nrmae backward and reward to 'move "the thread "carrying trumpets backward and forward along the spool upon which the thread is wound. Springs 7 5 and 76 secured upon collars 7 8 and 79 on the shaft 17 provide for cushioning the strokeof the lever 26 at each end of its tra'v'el.

When it is desired to wind shorter spools the bar 70 is secured upon the base 10 at the holes 72 and the pivot 69is secured at This shortens the throw otthe forward end of the arm 26 to provide for depositing th-eithread upon a shorter spool. When operating this form of the machine the thread is passed through the trumpets 66 and 67 and is woundupon two spools placed end to end upon the shaft 41.

It will be obvious to those skilled in the aft-that various changes be made in my device without departing from 'the' 'sp-irit of the invent-ion, and I, therefore, do not limit iiiy'sel-f-to \vhztt is shown in the "drawings and described in the specification, but only as "set lea-11 in the appended claims.
