Abstract
Abstract A router clamp for positioning and attaching a router having a housing to a radial saw arm so as to enable a user to accomplish overhead routing operations. The router clamp includes a bridge plate member affixed to a pair of inverted L-shaped brackets, one of the brackets being adjustably and removably affixed to the bridge plate member, a substantially cylindrical collar comprising two half sections for securing the router therein with the aid of an adjustable compression band to inwardly compress the half cylindrical sections of the collar against the router housing.

Claim 1
Independent Claim
177 words
A router clamp for attachment to a router having a housing, the router clamp including in combination a bridge plate member, a pair of inverted L-shaped brackets each bracket having an upper and lower portion, a substantially cylindrical collar and a compression band said bridge plate member being affixed to each upper portion of the pair of brackets, one of said brackets being adjustably and removably affixed to said bridge plate member by means of a slot, bolt and nut; the slot being disposed in the upper portion of said removably affixed bracket; said substantially cylindrical collar comprising two half sections, each half section being affixed to the lower portion of each of the pair of brackets, so as to define two longitudinal collar openings which allow the half sections to be compressible inwardly so as to contact and hold the housing of the router when the router is positioned therein and when the compression band is tightened over the longitudinal openings on the periphery of the collar to assist concentric gripping action of the half sections.
