Abstract
A hand-held nibbling machine has a manipulatable housing containing a motor and a transmission assembly for converting rotary motion to reciprocating linear motion. A tool assembly includes a housing portion, a ram reciprocatable in a passage in the housing portion, a base portion with a die support for supporting a die in spaced relationship to the adjacent end of the housing portion, and a neck portion between the housing and base portions providing a throat into which a workpiece may extend. Disengageable ram attachment elements are provided for securing the ram to the output coupling, and disengageable housing attachment elements are provided to secure the housing portion of the tool assembly to the manipulatable housing. An extension assembly is interposed between the tool assembly and manipulatable housing and is operative to transmit reciprocal motion from the output coupling to the ram of the tool assembly, and it comprises an elongated sleeve providing a passage therethrough and a shaft reciprocable therewithin. One end of the sleeve is engageable with the housing attachment means of the manipulatable housing, and the opposite end thereof has second housing attachment mean…
