Two friction wheels' attached at-tached to the cross feed re voire continually con-tinually in opposlto directions, and are thrown into gear by olectrio magnets. A pointer reaches from ' tho tool post to tho guage line that Is given to work from, and tho olectrio magnots take great care to keep tho latho tool in a position whero tho pointor just roaches tho gnnge line. Another man has Bet up behind his lnthe a battery of bis own make, and finds that it nssls's his eyesight woudorf ully. When ho wishes to see if ho has clamped his work on true, he seta in tho latho a tool that has a wire attached, and a bell rings tho instant it touches tho highest point of revolution. |
