2 Claims.

This invention relates-to machines for winding balls, such as golf balls, in which an elastic strand is wound under tension to form the ball.

It is an object of the invention to provide a device by means of which the tension applied to the elastic strand may be, progressively varied as the size of the ball increases during'winding.

It is a further object of the invention to provide a device in which the tension applied to the elastic strand may be progressively varied until the ball has reached a predetermined size, and may thereafter be maintained at constant level.

It is a further object of the invention to provide a device of this nature which may be built into a winding machine or may be applied to existing machines as an attachment.

Other objects and advantages of the invention will appeal hereinafter.

A preferred embodiment of the invention selected for purposes of illustration is shown in the accompanying drawings, in which,

Figure 1 is a front elevation of the device.

Figure 2 is a side elevation. Figure 3 is an enlarged detail view of the adjusting device.

Referring-i to the drawings, the invention is illustrated in'the form of an attachment for a winding machinein which the ball I is held and rotated by means o'froll'ers 2 mounted in'brackets 3 on shafts II and fi'. In accordance with usual practice the elastic strand 5 of rubber or other material to be wound is fed from a supply spool 6 around a pulley I, and thence to the ball. The pulley I is secured to a smaller pulley 8 on the same shaft, and a brake band 9 rides on this pulley. Secured to the end of the brake band is a weight Ill, and as will be apparent, the tension applied to the strand 5 may be increased .or decreased by increasing or decreasing the weight I0, which of course increases or decreases the friction applied to the pulley by the brake band.

According to the present invention the shafts 4 and I are provided respectively with ball bearings I2 and I2, the inner races of which are fast to the shafts and the outer races of which are connected to the forked arms I3, I3 of the bell crank levers It and I4 which terminate in meshing toothed segments I5, I5. Connected to said segments is a wire I6 which supports weight I'I. It will be understood that in winding machines where the balls being wound are supported by rollers, disks and the like, it is customary and essential that the supporting members be mounted to move apart during the winding operation in order to accommodate the increasing diameter of the ball. Thus in the machine illustrated, the supporting rollers 2 and their shafts 4 about their pivots I8, I8. lift the weight IT.

This movement is utilized in automatically varying the tension applied to the strand as the ball increases in diameter. is provided with an arm 20 which engages a nut 2I on the adjusting screw 22. This screw is connected to one end of the spring 23 by a ball and socket joint 24. The other end of the spring is connected to a lever 25, fulcrumed at 26. The other end of said lever is connected to rod 21 which carries weight IIL.

In using the device, before starting the winding operation, the spring 23 is disconnected from the lever 25, and the weight I0 is adjusted, by

This, in turn, will adding or removing one or more removable sections, to apply to the strand the maximum tension'which is intended to be applied during the winding operation. Then, the spring 23 is again connected to lever 25, and the tension of the spring 23 is adjusted by the adjusting screw 22. It will be obvious that the greater the tension applied to the spring 23, the less will be the effective weight of the weight III, and the less will be the tension on the strand. Consequently, the

the weight) will be applied to the strand, so

that by selecting a spring 23 of the proper length, the point in the winding operation when the maximum tension will be applied to the strand may be adjusted as desired. It will also be observed that once the tension on the spring 23 is relieved, the subsequent windings will be applied at constant maximum tension.

It will be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

I claim as my invention:

1. In a ball winding machine, in combination, a pair of oppositely disposed shafts supporting Thus, the weight I'I the ball being wound, said shafts being mounted for relative longitudinal movement, a weight connected to said shafts tending to move said shafts toward one another, said weight being movable as the ball increases in size, means for applying tension to the strand being wound, including a friction brake, and means operated by movements of said weight for varying the friction applied by said brake.

2. In a ball winding machine, in combination, a pair of oppositely disposed shafts supporting the ball being wound, said shafts being mounted for relative longitudinal movement, a weight connected to said shafts tending to move said shafts toward one another, said weight being movable as the ball increases in size, means for applying tension to the strand being wound, including a pulley, a brake band running over said pulley, and a weight connected to said brakeband, and a yielding connection between said weights such that movement of said' last named weight varies 10 the effective weight of said first named weight.
