Abstract
A self-adjusting accessory for a table saw that includes a guide for sliding in the guide groove of the work supporting table of a table saw and which is biased against the edge of the guide groove which is closest to the cutting blade. The guide bar is used in conjunction with the plurality of table saw fixtures such as a miter gauge, an alignment gauge and a stop gauge. The alignment gauge also forms part of apparatus for carrying out a method of verifying the straightness of the arbor for the cutting blade, the alignment of the arbor relative to the guide groove of the work supporting table and the flatness of the cutting blade. The invention also includes an apparatus for adjusting the alignment of the arbor relative to the guide groove of the work supporting table.
Claims19
A self-adjusting guide mechanism for attachment to a table saw fixture for sliding in a guide groove in the upper surface of the supporting table of a table saw, which guide groove has a bottom surface and a pair of opposed side surfaces, said guide mechanism comprising:
- (a) an elongated bar having a generally rectangular cross section, which includes a bottom surface, a first vertical side surface, and a second vertical side surface which is opposite said first side surface, said bar having a first horizontal bore which has a first opening in said first vertical side surface and a second horizontal bore which has a second opening in said first side surface;
- (b) a first plunger which has a free end, said first plunger being slidably mounted within said first bore between an outer position in which said first free end extends beyond said first vertical side surface and an inner position in which said first free end is within said first bore;
- (c) a second plunger which has a second free end, said second plunger being slidably mounted within said second bore between an outer position in which said second free end extends beyond said first vertical side surface, and an inner position in which said second free end is within said second bore;
- (d) a first biasing means for biasing said first plunger to its outer position;
- and
- (e) a second biasing means for biasing said second plunger to its outer position. whereby said first and second plungers are maintained in contact with one of the side surfaces of said guide groove by said first and second biasing means so that the second vertical side surface of said bar is maintained against the other of the side surfaces of said groove.
A self-adjusting accessory for a table saw which has a cutting blade and a work supporting table which has a guide groove which is parallel with the cutting blade, said guide groove having a bottom surface and a pair of opposed side surfaces, said self-adjusting accessory comprising:
- (a) an elongated guide bar for slidable mounting in the guide groove of said work supporting table, said guide bar having a generally rectangular cross section which includes a bottom surface, a first vertical side surface and a second vertical side surface which is opposite said first vertical side surface;
- (b) a saw fixture which is connected to said guide bar for sliding on said work supporting table;
- and
- (c) a least two spaced yieldable compensators which protrude from and are outwardly biased from the first vertical side surface for engaging one of the side surfaces of the guide groove in the work supporting table to maintain the second vertical side surface snugly against the other of the side surfaces of the guide groove.
