(Cl. 198--3l)
,
The present invention relates generally to an
improved device for use with conveyor systems
extensively employed in the bottling, canning,
and similar industries.
»
The invention is particularly applicable to that
type of conveyor system wherein a single line of

continued feeding of bottles to the other filling
