A key vise structure is disclosed wherein first and second vises are mounted on opposite ends of the frame and a movable vise jaw in each vise is moved by an end of a beam spring. The central portion of the beam spring is moved toward the vise jaws by means of a mechanical advantage means, shown in the preferred embodiment as a manual handle and a toggle mechanism. This simultaneously clamps both vises closed upon keys for use in a key machine. The key vise structure is also provided with a shoulder gauge for the key with a spring acting to yieldably urge the shoulder gauge into each of a gauging and a retracted position and this shoulder gauge is retracted by linkage means as the vises are moved to the clamped position. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter. |
