Abstract
The present invention provides an apparatus for holding a workpiece which, according to one aspect of the invention, has a pair of clamping members configured to securely hold a workpiece in which a mortise is to be formed. The clamps are mounted on a frame which has generally parallel longitudinal members that allow the workpiece to be operated on from opposite sides without repositioning the workpiece. The frame and clamping members are particularly configured for receiving and holding workpieces having a rounded cross-section.
Claims17
An apparatus for holding a workpiece while a mortise is formed in the workpiece by a mortising machine, said apparatus comprising:
- a frame having a longitudinal axis and first and second longitudinal members, wherein said longitudinal members lie generally parallel with said longitudinal axis, each on an opposite side of said longitudinal axis;
- a first and second clamp support connected to said frame and disposed between said first and second longitudinal members, said first clamp support being disposed proximate a longitudinal end of said frame and said second clamp support being disposed proximate the longitudinal end of said frame opposite said first clamp support;
- a first clamping member, disposed between said first and second longitudinal members and supported on said first clamp support, said clamping member being configured to hold the workpiece in which a mortise is to be formed;
- a second clamping member, disposed between said first and second longitudinal members and supported on said second clamp support, said second clamping member being configured to hold the workpiece in which a mortise is to be formed;
- and
- means for adjusting the position of said first and second clamping members on said clamp supports.

- a frame having a longitudinal axis and first and second longitudinal members, wherein said longitudinal members lie generally parallel with said longitudinal axis, each on an opposite side of said longitudinal axis;
- a first and second clamp support connected to said frame and disposed between said first and second longitudinal members, said first clamp support being disposed proximate a longitudinal end of said frame and said second clamp support being disposed proximate the longitudinal end of said frame opposite said first clamp support;
- a first clamping member, disposed between said first and second longitudinal members and supported on said first clamp support, said clamping member being configured to hold the workpiece in which a mortise is to be formed;
- a second clamping member, disposed between said first and second longitudinal members and supported on said second clamp support, said second clamping member being configured to hold the workpiece in which a mortise is to be formed;
- and
- means for adjusting the position of said first and second clamping members on said clamp supports, wherein said first clamping member and said second clamping member each comprise a pair of workpiece gripping members configured to receive a workpiece extending longitudinally between each pair of workpiece gripping members, said workpiece gripping members being adjustably mounted on said clamp supports to facilitate adjustment of the position of each workpiece gripping member on its respective clamp support and to facilitate the tightening of each workpiece gripping member against the workpiece, further wherein said first clamp support and said second clamp support each comprise a first rod and a second rod each of said rods extending between said first longitudinal member and said second longitudinal member, and further wherein said first longitudinal member and said second longitudinal member each comprises an edge configured for receiving and supporting the mortising machine in a position straddling said first and second longitudinal members.
