  • Patent number: 4292734
    Abstract: An in-line assembly machine is disclosed which is capable of commonly actuating tooling associated with the machine at a plurality of work stations. The machine includes a camshaft with a plurality of cams fixed thereto. Upper and lower elongated tool plates are also included. These elongated tool plates are reciprocated by first and second lifting rods, respectively, which are driven by the cams via followers. The rotation of the camshaft thus causes the upper and lower elongated tool plates to reciprocate, thereby commonly actuating tooling to perform operations on parts to be assembled.
