Application October 12, 1955, Serial No. 694,447 11 Claims

1. In a bowling alley pin resetting machine, apparatus for sorting pins from balls, comprising a conveyor belt, means mounting a span of said conveyor belt to extend at an inclination to the horizontal less than the critical inclination for transmission of conveying forces from said belt to a pin and greater than the critical inclination for transmission of conveying forces from said belt to a ball, means for driving said belt to cause said span to travel upwardly, means for discharging balls and pins onto said span, means for receiving pins from the upper end of said span, and means for receiving balls from the lower end of said span.

3. In a bowling alley pin resetting machine, apparatus for sorting pins from balls, comprising a first conveyor belt, means mounting a span of said conveyor belt to extend at an inclination to the horizontal less than the critical inclination for transmission of conveying forces from said belt to a pin, and greater than the critical inclination for transmission of conveying forces from said belt to a ball, means for driving said belt to cause said span to travel upwardly, a second conveyor belt, means mounting a span of said second conveyor belt at substantially the same level as said span of said first conveyor belt, said second span extending transversely to said first span, an elevator for elevating pins and balls from the pit of the bowling alley, said elevator being arranged to discharge elevated balls and pins onto said second span, a bar arranged above said second span and extending transversely thereto whereby to engage the head of a pin discharged from said elevator when such pin is oriented with its head leading and effective to prevent forward movement of said head while the base of such pin is carried forward by said second span, said second span being arranged to discharge balls and pins received from said elevator onto said first span, means for receiving pins from the upper end of said first span, and means for receiving balls from the lower end of said first span.

4. In a bowling alley pin resetting machine, apparatus for sorting pins from balls, comprising a first conveyor belt, means mounting a span of said conveyor belt to extend at an inclination to the horizontal less than the critical inclination for transmission of conveying forces from said belt to a pin, and greater than the critical inclination for transmission of conveying forces from said belt to a ball, means for driving said belt to cause said span to travel upwardly, a second conveyor belt, means mounting a span of said second conveyor belt at substantially the same level as said span of said second conveyor belt at substantially the same level as said span of said first belt, said second span extending transversely to said first span, a third conveyor belt, means mounting a span of said third conveyor belt closely adjacent and generally parallel to said span of said first conveyor belt on the side of said first conveyor belt remote from said second conveyor belt, said span of said third conveyor belt being spaced somewhat upwardly from said span of said first conveyor belt, an elevator for elevating pins and balls from the pit of the bowling alley, said elevator being arranged to discharge elevated balls and pins onto said second span, said second span being arranged to discharge balls and pins received from said elevator onto said first span with the bases of pins leading, means for receiving pins from the upper end of said first span, and means for receiving balls from the lower end of said first span.

7. In a bowling alley pin resetting machine, apparatus for sorting pins from balls, comprising a first conveyor belt, means mounting a span of said conveyor belt to extend at an inclination to the horizontal less than the critical inclination for transmission of conveying forces from said belt to a pin, and greater than the critical inclination for transmission of conveying forces from said belt to a ball, means for driving said belt to cause said span to travel upwardly, a second conveyor belt, means mounting a span of said second conveyor belt at substantially the same level as said span of said first conveyor belt, said second span extending transversely to said first span, an elevator for elevating pins and balls from the pit of the bowling alley, said elevator being arranged to discharge elevated balls and pins onto said second span, means for driving said elevator and said second conveyor belt, said second span being arranged to discharge balls and pins received from said elevator onto said first span, means for receiving balls from the lower end of said first span, means for counting the number of pins travelling upwardly along said first span to determine when a required predetermined number of pins has been fed a predetermined distance therealong, and means actuated by said counting means for discontinuing said means for driving said elevator and said second conveyor whereby to interrupt supply of pins and balls to said first span.
