Abstract: The invention relates to an apparatus for serially transferring objects between a supply conveyor and a receiving conveyor, in which the speed of the supply conveyor is not smaller than the speed of the receiving conveyor. The apparatus includes a feed cam which is inserted into the stream of supplied objects, an object being overtaken by pushing from behind in order to transfer it to the receiving conveyor means, whereby the feed cam must return for the transfer of each object outside of the serial stream of objects to its insertion location. The apparatus according to the invention comprises a four bar linkage with a drive crank (a), a coupling (b), a driven crank (c), and a stationary link (d) in which the feed cam is connected to the coupling (c) at a coupling point (C). The four bar linkage is designed such that it is an mechanism which additionally obeys certain conditions.
