ABSTRACT:
An inexpensive, portable hand-operated code key cutter is disclosed for reliable precision shear cutting of almost all common types of cylinder-lock keys comprising a body, a reciprocating punch, a pivoted hand lever, a cam-set holder movable vertically and laterally on said body and having a carriage for supporting the key blank, a punch rod with ratchet teeth and a driving pawl pivotally mounted on the hand lever near the main pivot axis, pawl-and-ratchet means for preventing retraction of the punch when the hand lever is released, a manual trip lever for releasing the pawls, a pivoted cam lever for lowering the cam-set holder in response to movement of the punch rod, and a cam lock for holding the cam lever in a fixed position during cutting. The house-key code cutter is capable of cutting to close tolerances and is remarkably well suited for use by the typical locksmith. The hand-carried shear cutter minimizes the time required for code selection, cutting and indexing and is ideal for on-site key changes at apartments, offices and motel rooms employing modern precision cylinder locks.
