Bearing sorting device

An apparatus for sorting round bearings according to their diameters comprising:

• a pair of out of round elongated cylinders having a high point and low point on the surface thereof,
• means for rotatably supporting said cylinders so that the longitudinal axis thereof are diverging and a sorting gap between the surfaces of said cylinders increases from one end to the other end,
• means for carrying said cylinders on an incline with said cylinders sloping downwardly from said one end to said other end,
• means connected to one end of said cylinders for rotating said cylinders in opposite direction,
• timing means positively synchronizing the rotation of said cylinders relative to each other so that the high point on one of said cylinders meets the low point of said other cylinder at said sorting gap on each revolution of said cylinders,
• means for feeding said round bearings to be sorted adjacent the upper end of said sorting gap,
• a plurality of receptacles carried below said sorting gap for receiving said round bearings as they drop through said sorting gap,
• a shaft extending through each of said cylinders, first bearings carried on the ends of said shafts, resilient support means connected to said first bearings for supporting the majority of the weight of said cylinders and shafts, and
• a guide bearing carried on each of said cylinders for positively positioning and supporting said cylinders relative to each other,
• whereby said bearings travel down said cylinders over said sorting gap until the bearings reach a point where the sorting gap is larger than said bearings and said bearings drop through to one of said receptacles.
