Abstract
In a rotary cutter block a blade is clamped in an inwardly divergent recess by a wedge. A spring positioned between the cutter block and the wedge takes up any slack when the wedge is loosened thereby eliminating the need for operator manipulation of the wedge, blade and optional backing plate for the blade during setting of the blade. Also provided is a cam means for incrementally adjusting the blade outwardly of the cutter block.
Claims26
A rotary cutter head for woodworking machinery comprising:
- a cylindrical cutterblock body;
- a plurality of inwardly divergent recesses formed in said cutterblock body;
- a cutter blade positioned in each of said recesses;
- clamp means in each of said recesses, said clamp means each comprising a wedge and screw means associated with the wedge, the screw means being tightenable against a face of a recess to urge the wedge into direct contact with an associated cutter blade positioned in the said recess to clamp the blade in the recess;
- and
- resilient means in each recess, each resilient means acting on an associated clamp means to lightly hold the cutter blade in position on slackening of the associated screw means.
A rotary cutter head for woodworking machinery, comprising a cutterblock body formed with a number of inwardly divergent recesses each receiving a cutter blade held therein by clamp means, wherein each clamp means comprises a wedge and associated screw means for clamping the cutter blade in the recess, and each clamp means incorporates at least one resilient means extending partially from a recess in the wedge to hold the cutter blade lightly in position on slackening of the screw means.
