Abstract
The alignment mechanism includes a main body, a clamp which is connected to the main body for clamping the main body to the frame of a jointer and for creating a tension on the rotor of the jointer against rotation of the rotor about its drive axis. The clamping elements also include rotor adjusting elements connected to the main body for applying torque to the rotor to overcome the clamping tension on the rotor. The alignment mechanism also includes a reference member connected to the main body to provide a reference surface for aligning the cutting blades of the rotor to the top dead center position.
Claims13
An alignment mechanism for a jointer having a line of feed for a workpiece, said jointer having a frame;
- an infeed table which has a horizontal surface and a horizontal first end edge which is transverse to said line of feed;
- an outfeed table which has a horizontal upper surface and a horizontal second end edge which is transverse to said line of feed and spaced from said first end edge to define with said outer edge a cutting gap;
- a horizontal rotor which is mounted on said frame for rotation about a horizontal drive axis which is vertically aligned with said gap;
- and at least one cutting blade which is adjustably mounted on said rotor for adjustably positioning said horizontal cutting edge toward and away form said gap, said alignment mechanism comprising:
- (a) a main body;
- (b) clamping means for clamping said main body to the said frame of the jointer adjacent one end of the cutting gap and to the rotor of the jointer for maintaining said body in a fixed position relative to said frame and the horizontal drive axis of the rotor and for creating a tension on said rotor against rotation of said rotor about said drive axis for enabling said rotor to rotate about said drive axis upon the application of a torque to said rotor which is sufficient to overcome said tension;
- (c) a reference member which is mounted to said main body and which extends toward said gap when said alignment device is applied to said jointer, said reference member having a reference edge;
- and
- (d) leveling means operatively connected to said main body for adjusting the position of said reference member relative to the horizontal surface of said outfeed table to position said reference edge in vertical alignment with said horizontal driving axis.

- a horizontal rotor which is mounted on said frame for rotation about a horizontal drive axis which is vertically aligned with said gap;
- and at least one cutting blade which is adjustably mounted on said rotor for adjustably positioning said horizontal cutting edge toward and away form said gap, said alignment mechanism comprising:
- (a) a main body;
- (b) clamping means for clamping said maid body to the frame of the jointer adjacent one end of the cutting gap and to the rotor of the jointer for maintaining said body in a fixed position relative to the frame and the horizontal drive axis of the jointer and for creating a tension on said rotor against rotation of said rotor about said drive axis for enabling said rotor to rotate about said drive axis upon the application of a torque to said rotor which is sufficient to overcome said tension;
- and
- (c) rotor adjusting means operatively connected to said main body for applying a torque to said rotor which is sufficient to overcome said tension and adjustably rotate said rotor.
