  • Patent number: 5456168
    Abstract: The marking device for marking indicia onto manufactured parts includes a body portion having a recess. Into the recess and the body portion fits a stamp retainer block which also has a recess. Into the recess on the stamp retainer block fits type members which create the indicia on the manufactured part. Such indicia might be the part number or date of manufacture, or other such information useful in the manufacturing process. A second stamp retainer block may be advantageously utilized, by loading a second set of type members into the second stamp retainer block so that the first stamp retainer block can be quickly removed and the second stamp retainer block quickly inserted into the body portion of the marking device. Such insertion may be done by inserting a rod into a channel and depressing a spring loaded ball.
