Abstract

Drive for producing motion with intervening dwells including a four-bar linkage defining a couple curve travel path traversible only in part and having equally coincident forward and return paths, and a dwell-producing driven rocker arm pair connected thereto, the couple curve travel path having a vertex therein dividing the couple curve travel path into a short curve path for producing a dwell and an elongated curve path extending at an angle to the short curve path for producing a movement, the vertex of the couple curve being identical with an instantaneous pole defining the start and end of the dwell.
