Abstract

Apparatus for moving containers such as bottles to and from a position in which each container is fixed, at least during a predetermined interval of time. The apparatus comprises a feed screw and a discharge screw separated from one another to define a station therebetween at which each container is periodically halted. A wall extends along each screw and cooperates therewith to guide each container respectively into and from the station. A rotatable sprocket is mounted at the station and has adjacent teeth between which the containers are successively received from the feed screw and fed to the discharge screw. The sprocket is freely rotatable and undergoes stepwise movement under the action of contact of the successive containers with the teeth of the sprocket. Each container is fed by the feed screw to the station to cause the sprocket to rotate and to position the container at the station between the feed screw and the discharge screw, the previously halted container at the station being advanced by the rotation of the sprocket to travel to the discharge screw.
