Title: Improvements in and relating to golf ball recoating
IPC: B29D99/00

Abstract: <PICT:0493724/III/1> <PICT:0493724/III/2> <PICT:0493724/III/3> <PICT:0493724/III/4> <PICT:0493724/III/5> Used golf balls are recoated by a dipping operation in a machine in which a conveyer arm moving in a vertical plane carries a ball from a position beneath the surface of the coating liquid to a position above the surface where it remains for a predetermined period to drain, and then to a higher position in which it is further drained in an inverted position and finally spun to dry the coating.  The machine is automatic and may be cam-operated. Balls are fed into the hopper 231 and delivered singly at predetermined time intervals by the rotating disc 23 to the shoot 90 in the position 89, Fig. 4, where the ball is received by the arm 14 and lowered into the coating liquid in the spout 110 of the container 22.  From the position 99 the ball is raised to the draining position 88 and kept there for a predetermined period before being returned to the position 89, where it is grasped by the holders 173 rotatably mounted on the jaws 156 and is moved to the right to enable a second ball to be dropped into the position 89.  An airtight lid 114 is kept in position over the end of the spout 110 except when the arm 14 is in its highest position, in order to prevent evaporation of volatile solvent from the coating composition.  As the jaws 156 move to the right, the hub 175 engages with a raised part 183 on the rail 184 causing the jaws to rotate sufficiently to invert the coated ball and then allow it to drain.  Further movement in the same direction brings the pulley 187 into contact with the rotating wheel 188, causing the ball to be spun rapidly and dried, until the hub 175 rides up on the raised portion 199 of the rail 184, whereby the rotation is stopped just before the jaws 156 open to drop the finished ball upon the inclined track 198 delivering to the pocket 241.  The drive of the machine is furnished by an electric motor 2 driving the main shaft 1 through a belt 3, worm 6, gear wheel 7, pinion 8 and gear wheel 9.  The various movements of the ball feed disc, the dipping arm and the spinning jaws are effected in timed sequence by means of appropriate cam and lever mechanisms attached to or working from the main shaft 1.  Coin-operated control.-When a suitable coin is dropped into the slot 250, Fig. 8, it trips a lever 251 closing the electrical circuit between contacts 252, 253, and comes to rest in position 255, from which it is subsequently discharged into a box 260 by a slider 258 operated by the bar 28, Fig. 2.  The machine continues in operation until a lever 264 is moved to the left by a pin 262 on the wheel 263, whereby the pin 266 is moved to the right to allow the lever 251 to return to its original position under the action of a spring 251a, the contacts at 252, 253 being separated.  The wheel 263 is rotated by a cam and lever on the main shaft 1 actuating a pawl engaging the ratchet wheel 276.  By adjusting the number of pins 262 in relation to the number of teeth in the wheel 276 the machine can be made to coat one, two or more balls for each coin inserted.
