Three-Legged Router: A T-Frame on the Table Beside the Work, Its Depth Set by a Knob While Cutting (Willard & Young, 1939)

Homer E. Willard and Frederick S. Young of Toledo, Ohio, received US 2,146,458, dated 7 February 1939, for a simple portable router with few moving parts. The motor sits in an open-fronted support in the middle of a T-shaped frame, so the bit and the work are always in view. The frame stands on three legs on the table beside the clamped work: two curved legs at one end, and at the other a screw with a knob. Turning the knob with one hand raises or lowers the bit while it cuts. We print the frame in PETG round a small DC motor. The sizes are ours.

Fit the motor

Print the frame. Fit the collet adapter on the motor's shaft, stand the motor in the support with its face on the ledge and the collet through the hole, and screw it down with two M4 screws. Wire it through a toggle switch to the DC supply as for our 1924 router.

The screw leg and knob

Press an M10 nut into the trap under the boss. Cut 100 mm of M10 threaded rod, round its lower end with a file so it slides on the table, and screw it up through the nut. Turn a hardwood knob 25, bore it, and glue it on the rod's top with a nut locked under it.

Rout

Clamp the work down on the table between two strips. Fit a bit and stand the router on the table so its legs are beside the work and the bit is over it. Turn the knob until the bit just clears the work, switch on, and turn it down a little while moving the router over the area to be cut, one hand on arm 11 and the other on the knob.

History and honest limits

**Homer E. Willard** and **Frederick S. Young** of Toledo, Ohio, US 2,146,458, dated 7 February 1939, filed 11 December 1935. They claimed "a portable router comprising a T-shaped frame having a semi-circular recess in the stem of the T, a bit-operating motor mounted in said recess and a leg projecting in the same direction as the bit from each of the ends of the frame", one leg "screw-threaded through the arm and terminating above the arm in an operating knob". Their work was an electrotype clamped on the table; their motor ran on mains. Ours is a small DC motor in a printed frame. They give no sizes; every size here is ours.
