Abstract
Abstract The routing fixture constitutes a table comprised of two flat panels separated by a slot. Tubular rails function as a track for guiding a carriage in a direction parallel to the slot, the carriage supporting a motor-operated router. The carriage includes a handle-actuated platform by which the router, which is attached to the platform, can be moved toward and away from the slot. The insertion or removal of shims permits thicker or thinner stock, as the case may be, to be worked on. Specially designed clamps hold the stock or work in a fixed relationship while the carriage and the router are moved relative thereto; another specially designed clamp holds the carriage fixed when the stock or work is to be moved relative to the carriage. The carriage is mounted for virtually frictionalless movement by reason of certain bearings associated with the supporting of the carriage. Lateral extensions enable relatively large pieces of work to be accommodated on the table or fixture. Various bolts are employed for holding the table together so that it can be easily shipped in a disassembled condition and then assembled by the purchaser.

The routing fixture defined in claim 8 in which said clamping means includes a pair of spaced posts projecting from one of said channel members, one of said posts being located at one side of one of said rails and the other of said posts to the other side thereof, a coil spring encircling each post, a clamping strip having holes in its ends for accommodating the projecting ends of said posts, said projecting post ends being threaded, and a threaded member carried on each of said projecting threaded ends, whereby tightening of one of said threaded members forces said clamping strip against said one rail to prevent said longitudinal movement of said carriage means.
Claim 11
Dependent Claim
16 words
The routing fixture defined in claim 9 in which said one threaded member constitutes a knob.
Claim 12
Dependent Claim
19 words
The routing fixture defined in claim 8 including means for clamping the work to be routed against said panels.
