Abstract
Apparatus for filling containers alternately with predetermined quantities of material has two container positions to be fed alternately and a material guide arrangement with alternative outlets that supply the material to containers at these two positions. A pair of container support frames are arranged side by side on the front pair of a main frame, and these support frames are mounted by pivot arms to the main frame in a parallelogram arrangement. Rearwardly of the main frame front part are counterweights or counterbalances supported on either upper or lower ones of the pivot arms. An upper part of each of the support frames has a mechanism that coacts with a cooperating mechanism on the material guide arrangement to change the position of a diverter plate when the container that is being filled overbalances the corresponding counterbalance and causes the associated support frame to descend. All of the cooperating parts to effect this are disposed within the vertical extent of the diverter plate, and all on one side of the main frame.
