Abstract

A table saw has a circular saw table, a miter table and a supplementary table to form a working table, on the front and rear sides of which two guide rails are disposed slidably with respect to the working table. The miter table has a miter fence thereon whose pivot points are provided at two separate positions.

Claims

1. A table saw having a circular saw table for supporting a circular saw for cutting a work, a miter table disposed adjacent a side of said circular saw table and having a miter fence thereon for guiding said work to said circular saw and a supplementary table cooperating with said two tables for supporting said work, said three tables being disposed so as to form a working table, said working table having front and rear directions, the improvement in which a pair of guide rails are disposed laterally on front and rear sides of said working table, respectively, and said miter table and supplementary table are slidably relative to said saw table along said guide rails so as to be fastened at their desired positions and detachably mounted thereon, said miter table being slidably in the front and rear directions of said working table in a state wherein an upper face of said miter table is approximately flush with an upper face of said circular saw table.

2. A table saw according to claim 1, wherein said saw table has a cutting portion at which said work is cut, said cutting portion is provided with a splitter for preventing said work having just been split by a saw from fastening side faces of said saw and a repulsive prevention means for preventing said work having been cut from jumping upwardly, said cutting portion being also provided with an opening through which said saw is projected, said opening being defined by a pair of cutting edge plates made of resin, a pair of guard plates made of hard material being provided, at a position corresponding to said splitter and repulsive prevention means.

3. A table saw having a circular saw table for supporting a circular saw for cutting a work, a miter table disposed adjacent a side of said circular saw table and having a miter fence thereon for guiding said work to said circular saw and a supplementary table cooperating with said two tables for supporting said work, said three tables being disposed so as to form a working table, said working table having front and rear directions, the improvement in which a pair of guide rails are disposed laterally on front and rear sides of said working table, respectively, and said miter table being provided detachably on a guide plate which is moved slidably along said guide rails so as to be fastened at a desired position, said miter table being slidably and fixable with respect to said guide plate in the front and rear direction of said working table.

4. A table saw according to claim 3, wherein said guide rails comprise front and rear guide rails, said front guide rail having an engaging groove along which a slide bar provided detachably on a lower surface of said guide plate is slidable in a lateral direction, said slide bar and guide plate being fastened on said guide rails by a guide plate fastening means, said guide plate being slidable on said guide rails in said lateral direction and detachably fixed to said guide rails.

5. A table saw according to claim 4, wherein said guide plate has a means for adjusting a position thereof, in a front and rear position of said working table, said guide plate being mounted at the front and rear position of said work table with respect to said guide rails.

6. A table saw having a circular saw table for supporting a circular saw for cutting a work, a miter table disposed adjacent to said circular saw table and having a miter fence thereon for guiding said work to said circular saw and a supplementary table cooperating with said circular saw and miter tables for supporting said work, said three tables being disposed so as to form a working table, the improvement in which a pair of guide rails are disposed laterally on front and rear sides of said working table, respectively, said miter table and said supplementary table are moved slidingly along said guide rails so as to be fastened at their desired positions and detachably mounted thereon, said guide rails are slidably moved laterally on a side face of said working table, respectively, one of each guide rail and said working table has a side engaging groove for engaging an engaging element provided on the other of each guide rail and said working table, and each guide rail is fastened on said working table at a desired position by a fastening means.

7. A table saw according to claim 6, wherein one of said front or rear guide rail has a scale which is movable along said guide rail so that the location of said scale can be adjusted.

8. A table saw according to claim 7, wherein said scale is detachably mounted on said guide rail at a desired position by a clamping member which can be moved in said lateral direction so that its clamping position is adjustable in said lateral direction.
