Abstract
Stabilizing apparatus for controlling the position of a workpiece relative to a tool. The stabilizing apparatus includes an elongated base for attachment to the tool, an elongated adjustable support that is essentially parallel to the base, and an interconnecting structure that enables the adjustable support to move relative to the base. When a workpiece moves toward the tool, it displaces the adjustable support toward the base thereby compressing springs in the interconnecting structure. This produces a clamping force against an opposed work support surface that stabilizes the position of the workpiece transversely to the direction of travel but allows movement along the work path. Multiple stabilizing apparatus can be used to provide both vertical and horizontal clamping forces.
Claims28
Stabilizing apparatus for use with a tool having first and second perpendicular planar work surfaces, said apparatus including stabilizing means for supporting a workpiece for motion relative thereto, said stabilizing means comprising:
- A. elongated base means for attachment to one of the first and second work surfaces,
- B. elongated adjustable support means substantially parallel to said elongated base means for defining a work piece support plane that is displaced from the other of said first and second work surfaces, and
- C. a plurality of spaced interconnection means affixed to said elongated adjustable support means and biased against said elongated base means for enabling said elongated adjustable support means to move relative to said elongated base means and the other of the first and second work surfaces thereby to define a channel between the other of the first and second work surfaces and said elongated adjustable support means for stabilizing the position of the work piece against the other of the first and second work surfaces.
Apparatus for use with a tool having a workpiece modifying component positioned at a tool work plane and a first planar work surface for supporting a workpiece for motion relative to the workpiece modifying component, said apparatus comprising:
- A. elongated fence means for attachment to the tool for establishing a second planar work surface perpendicular to said first planar work surface, and
- B. stabilizing means for controlling the relative displacement of a workpiece and the workpiece modifying component including:
- i. elongated base means for attachment to one of said first and second work surfaces,
- ii. elongated adjustable support means displaced from and substantially parallel to said elongated base means for defining a second work piece support plane that is displaced from and substantially parallel to the tool work plane, and
- iii. interconnection means engaging said elongated base means and said elongated adjustable support means for enabling said elongated adjustable support means to move relative to said elongated base means thereby to define a channel between said elongated adjustable support means and the other of said first and second work surfaces for stabilizing the position of the work piece against the other of the first and second work surfaces.
