Abstract:
An oscillator apparatus for sorting out pieces of lumber wherein comprising:a base assembly including leg members and elongate side members interconnecting pairs of said leg members, said base assembly further including pairs of first and second gusset members being attached to where said elongate side members are joined to said leg members, and also including pairs of first and second bearings being securely disposed in said pairs of said first and second gusset members, and further including cross members interconnecting pairs of said leg members; a table assembly being movably mounted upon said base assembly, and also including a frame having side rail members and an end rail member being attached to and interconnecting ends of said side rail members, said table assembly further including panels being longitudinally spaced apart thus forming gaps, said panels being attached in said frame for supporting wood to be sorted with pieces of wood dropping through said gaps; and an oscillator assembly being mounted to said base assembly for oscillating said table assembly, said oscillator assembly includes including pairs of first and second bearing members being disposed in said side rail members of said table assembly near ends thereof, and also includes including a camshaft being journaled through said first bearing members and in said first bearings and being in contactable relationship to said table assembly for the oscillation thereof, and further includes including an elongate shaft member being journaled through said second bearing members and also includes including stub shafts being journaled in said second bearings, and further includes including linkage members being attached to said stub shafts and to said elongate shaft member for essentially swinging the table assembly, and also includes including a first pulley being mounted to an end of said camshaft, and also includes including a motor being mounted to said base assembly and having a shaft and being connectable to a power source, and further includes including a second pulley being mounted to said shaft of said motor, and also includes including an endless belt being carried about said first and second pulleys, said camshaft having an intermediate portion being generally offset from end portions thereof thus causing oscillation of said panels.
