Rack-and-Pinion Router With a Zero-Set Knob: Two Knobs on One Hollow Pinion, Set to Zero on the Work (Rees, 1969)
Spencer C. Rees of Pickens, South Carolina, received US 3,466,973, dated 16 September 1969, for The Singer Company. A rack screwed to the motor housing is moved by a pinion through a window in a box on the base. The pinion is a hollow shaft running in one bore through the box's two side lugs, with a knob at each end. One knob turns it. The other, a zero-set knob with graduations, slips on its sleeve against an O-ring, so it can be set to zero with the bit touching the work. One screw through the middle holds it all together. Only the pinion shaft was metal; the rest was moulded.
We print every part in PETG round a small DC motor. The sizes are ours.

"The zero-set knob 40 has a reduced diameter portion 51 which carries circumferentially-spaced graduation marks 52 on its surface." "In the above-described structure it will be noted that the only metallic part required is the pinion shaft 37 which is a relatively simple two-diameter piece."

Pinion, knobs and cover
Push the pinion shaft through the box's bore from the right, its toothed part through the window meshing with the rack, its bearing part in the right lug. Fit the O-ring in the zero-set knob's groove, push the sleeve into the knob, and slide them onto the shaft's toothed end from the left, the sleeve in the left lug. Fit the adjusting knob on the right end, its grooves on the shaft's ribs. Pass a long M4 screw through knob, shaft and sleeve with a washer, into a nut in the sleeve, and tighten it until the knobs have only a little end play. Screw the cover over the box with two M3 screws.

Fit a bit. Loosen the clamp, turn the adjusting knob until the bit's tip touches the work, then turn the zero-set knob alone until its zero lines up with the cover's mark. Turn the adjusting knob to the depth wanted, read off the graduations, and clamp. Rout with both hands on the handles.

**Spencer C. Rees** of Pickens, South Carolina, assignor to The Singer Company, US 3,466,973, dated 16 September 1969, filed 8 January 1968. He claimed a rack on the motor housing, "a pair of lugs formed on the base in fixed spaced relation on opposite sides of the rack and having aligned cylindrical apertures", a hollow pinion shaft, an adjusting knob, a flanged sleeve, "a zero-set knob frictionally coupled to said sleeve", and "single fastening means" through them all. His pinion shaft was metal and the rest moulded; ours is all printed. His motor ran on mains; ours is a small DC motor. He gives no sizes; every size here is ours.
