(under subclass 53) Device provided with means for moving the pin, causing the pin to penetrate the work.
(1) Note. The mere extension of a pivoted-pin supporting member, forming a simple lever, is not considered to result in a drive means for purposes of placement in this subclass. Likewise, means for merely holding a pin in a raised position and subsequently allowing it to drop under the influence of gravity does not constitute drive means for this subclass.
