ABSTRACT:
This disclosure is directed to a pallet locating and positioning apparatus for use on a screen printing machine having an oval track about which a series of pallets supporting work pieces are indexed from station to station. An internal surface of a side rail of a hollow rectangular pallet engages outwardly biased detenting fingers which are affixed on adjacent parallel lateral edges of a pallet base plate driven about the endless track of the screen printing machine. One finger engages a complementary shaped notch in the side rails accurately detenting the pallet along the longitudinal axis of the pallet base plate. Another finger is in touching engagement with a straight portion of the same side rail urging the pallet outwardly from the adjacent parallel edges of the pallet base plate to which the fingers are attached, thereby causing the internal surface of an opposed parallel side rail of the pallet to come into touching engagement with an opposed lateral edge of the pallet base plate, thereby preventing shifting of the pallet in a direction transverse to the longitudinal axis of the pallet base plate.
