Abstract

A router table consisting of a table top formed by two slabs separated by a gap, a raised fence at an end of the table intersected by the gap and bridging the gap, a carriage mounted in the gap for movement toward and from the fence, a router mounted beneath the carriage and including a router bit projecting above the table, the fence being windowed to permit said router bit to pass the plane of the fence if desired in order that the bit may be used to plane the edge of a work piece guided across the table by the fence, the fence being formed of relatively movable sections wich may be offset transversely of the normal fence plane to compensate for any thickness of the work piece edge cut away by the bit, or to close the window when its use is not desired.

Claims

1. A router table comprising:

a. a table having a planar top surface and comprising a pair of coplanar slabs spaced apart to present a parallel-sided gap therebetween,

b. a fence disposed along one edge of said table and rising above the top surface thereof whereby a work piece may be guided thereby in a straight line across said table top, the gap between said slabs being disposed at right angles to said fence,

c. a carriage having its upper surface coplanar with said slabs mounted slidably between said slabs for movement in said gap at right angles to said fence, and

d. a router including a drive unit and a router bit rotatable on a vertical axis, said router drive unit being mounted beneath said carriage and said router bit projecting upwardly through an aperture of said carriage not larger than required to permit free rotation of the bit, the top surface of said carriage extending substantial distances in all directions from said bit aperture to provide solid support for the work piece in the area surrounding said bit.

2. A router table as recited in claim 2 with the addition of a filler plate carried slidably by said table slabs, said filler plate bridging the gap between said slabs and being slidable in a direction at right angles to said fence, said filler plate having an aperture formed therein elongated in a direction at right angles to the fence, and also having transversely uninterrupted portions at the ends of said aperture, said carriage extending upwardly through said aperture to be flush with the filler plate and table slabs, said filler plate and carriage being relatively movable at right angles to the fence, whereby a transversely uninterrupted portion of the filler plate may be disposed directly adjacent said fence, to provide solid support for the work piece, at any position of said carriage relative to said fence.

3. A router table as recited in claim 2 wherein said fence is notched upwardly from its lower edge to permit both said carriage and said filler plate to be extended therethrough, whereby said router bit may be disposed closely adjacent said fence.

4. A router table as recited in claim 2 wherein the horizontal extent to which said router may be moved at right angles to said fence is sufficiently great that said router bit may be moved through the plane of said fence, said fence having a window formed therethrough to permit said bit to do so, whereby said router bit may be utilized to plane or shape the edge of the work piece being guided against said fence.

5. A router table as recited in claim 4 with the addition of means operable to selectively cover or uncover said fence window, depending on whether its use is or is not desired in any given operation.

6. A router table as recited in claim 4 wherein the portion of said fence at the trailing side of said bit is adjustably movable outwardly over the table surface, whereby to compensate for any thickness of the work piece edge removed by said bit and provide for accurate guidance of the work piece at both sides of the router bit.

7. A router table as recited in claim 6 wherein said fence comprises a section at the leading side of the router bit and a section at the trailing side of the bit, the leading and trailing sections being relatively movable transversely to the vertical plane of the fence from a position in which they are coplanar to a position in which the trailing fence section is spaced inwardly over the table relative to the leading section, whereby to compensate for any thickness of the work piece edge removed by said bit.

8. A router table as recited in claim 7 wherein said window is formed in one of said fence members adjacent its juncture with the other of said members, and wherein said fence members are also relatively movable in a direction parallel to said fence, whereby one of said fence members selectively covers or uncovers the window opening of the other.
