A great deal of money may be saved iu maehine shops bya relatively small investment in micrometer calipers togetherWilli graduated dials on the cross screws of machine T. Slocomb & Company, manufacturers of micrometers,Providence, R. I., have used dials, as illustrated in the accom-panying engaving, for a number of years and the idea seemsto us excellent. They do not make them, but strongly advocatetheir use. They are not expensive and they certainly savetime, labor and spoiled work. Several makers put these dialson their lathes, but they are usually too small in diameterand the graduations are too fine. At the shops referred tothe discs are fitted in the place of the usual ball crank. Astraight fit is turned on the quill extending from the latheapron, and the pointer, which is split and held by a bindingscrew, is fitted to permit of turning sizes for accurate fits by the most. Graduated Dials on Lathes. direct methods possible and without the usual cut and tryprocess. The work is simply rounded up and measured withthe micrometer, which shows how many thousandths are tocome off; then, by the reading on the dial, the cutting tool isadjusted to take off the exact amount desired, with littlechance for mistake and securing a great saving of time. Thesepeople say that any machinist of ordinary ability will nevergive them up when he has employed them long enough to be-come used to them. J. T. Slocomb & Company manufacturecalipers for all-around machine shop work and they recom-mend them in place of all other outside gauges for work thatis at all close. These micrometer calipers used in connectionwith the micrometer dials fill two long-felt wants; first, anaccurate method of measuring work, and second, an accurateway for adjusting cutting tools in accordance with thesemeasurements.
