US 5,855,234 A · Router table assembly with microset throat plate

Abstract

A router table assembly includes a removable throat plate having a frame with a generally-planar upper surface, and an opening formed in the frame's upper surface. A disc, supported within the opening for rotation about a first axis, includes a through-hole which is sized to permit extension therethrough of a routing bit along a second axis parallel to the first axis. A graduated scale on the frame adjacent to the disc cooperates with a reference mark on the disk to provide an indication of the displacement of the bit's second axis relative to a reference edge on the working surface. A clamp secures the disc against rotation after the disc has been rotated within the frame to position the bit's second axis a desired distance from the reference edge. A fence is secured in one of a plurality of parallel-spaced positions relative to the reference edge.

Dependent claims

A throat plate for supporting a router beneath a working surface of a router table such that a tool driven by the router extends above the working surface, the throat plate comprising:

a frame having an upper surface with which to define a first portion of the working surface, and an opening formed in the upper surface of the frame;
a disc supported within the opening of the frame for rotation about a first axis generally orthogonal to the upper surface of the frame, the disc having an upper surface with which to define a second portion of the working surface, and a through-hole intersecting the upper surface of the disc, the through-hole being sized to permit extension therethrough of the routing tool along a second axis generally parallel to the first axis;
and
a clamp for securing the disc against rotation relative to the frame.
