Abstract
A key punch apparatus is provided for selectively removing notches of material from a key blank. The apparatus includes a punch and die subassembly which is rotatable between first and second positions. A carrier holds the key blank in an operative relation with the subassembly. An actuating handle is operatively coupled to the punch to cause an axial cutting stroke. Cutting a notch with the subassembly in the first position results in a notch having a first shape, while cutting a notch with the subassembly in the second position results in a notch having a second shape.
Claims6
A key punch apparatus for removing material selectively from a key blank, said apparatus comprising:
- a base;
- an actuating handle operatively coupled to said punch such that manipulation of said handle moves said punch along said axis on a cutting stroke to remove said material from said key blank;
- and
- a carrier means mounted on said apparatus for supporting said key blank thereon in operative relation to said punch, said carrier means having first and second datum surfaces disposed perpendicularly to one another, and means for fixedly securing said blank in abutting engagement with said surfaces, said carrier means being positionable by a first locating means to locate said blank in a selected one of a series of predetermined positions;
- said first locating means comprising:
- two circular oppositely disposed end sections having a common axis, said end sections being supported by said base for rotational movement therein;
- an extension of one said end section on said common axis;
- a ring concentrically disposed around said extension;
- an adjustment screw extending radially through said ring and positioned to engage said extension to rotationally secure said ring to said extension;
- a knob concentrically disposed around an outer side of said ring;
- a locating pin extending radially through said knob and said ring to rotationally secure said knob to said ring;
- and
- a shaft member disposed between said two end sections, said shaft member having a central axis which is offset from said common axis so that rotation of said end sections causes eccentric rotation of said shaft member;
- said shaft member being operably connected to said carrier means to cause said carrier means and said key blank thereon to be movable in a direction parallel to said first datum surface.
