This invention relates to mechanism by which‘
various articles may be positioned in a predeter
mined manner, it being of especial utility in
determining the direction of advance of such
headed articles as shells for cartridges. The
present case is a division of the application for
improvements in distributing apparatus ?led in

to adapt the device to operate effectively upon
a wide range ‘of sizes and weights of articles. “It
