  • Patent number: 4801235
    Abstract: A motor driven device for transferring workpieces between two stations possesses a holding device for the workpieces arranged on the lower end of a lever linkage. This linkage comprises an operating lever, which at its top end articulates with a crank lever, which pivots about a stationary crank lever axis. The center part of the operating lever articulates with the free end of a guide lever which at its other end pivots about a stationary guide lever axis under the crank lever axis. During transfer motion the linkage runs through a center position, in which the guide lever, the upper lever arm of the operating lever and the upwardly directed crank lever are on a straight line. At one stationary lever axis there is a driven shaft which is keyed to the lever thereat.
