Page 16 - To read the micrometer, therefore, multiply the number of vertical divisions visible on the sleeve by 25, and add the number of divisions on the bevel of the thimble, from 0 to the line which coincides with the horizontal line on the sleeve. For example, as the tool is represented in the engraving, there are ten divisions visible on the sleeve.
Page 16 - The pitch of the screw threads on the concealed part of the spindle is 40 to an inch. One complete revolution of the spindle therefore moves it longitudinally one fortieth (or twenty-five thousandths) of an inch. The sleeve D is marked with 40 lines to the inch, corresponding to the number of threads on the spindle.
Page 16 - The beveled edge of the thimble is marked in twenty-five divisions, and every fifth line is numbered from 0 to 25. Rotating the thimble from one of these marks to the next moves the spindle longitudinally %s of twentyfive thousandths or one-thousandth of an inch.
Page 12 - To construct a parabola: Divide line AB into a number of equal parts and divide BC into the same number of parts. From the division points on AB, draw horizontal lines. From the division points on BC, draw lines to point A. The points of intersection between lines drawn from points numbered alike are points on the parabola. To construct a hyperbola: From focus F, lay off a distance FD equal to the transverse axis, or the distance AB between the two branches of the curve. With F as a center and any...

Page 12 - FD, 1| inches above and below A B. Let A be the vertex of the parabola. Divide AE into any number of equal parts and divide EC into the same number of equal parts. Through the points of division, R, S, T, U and V, draw horizontal lines and connect L, M, N, O and P, with A. The intersections of the horizontal lines with the oblique lines are points on the curve. For instance, the intersection of AL and the line V is one point and the intersection...
Page 16 - One complete revolution of the spindle, therefore, moves it lengthwise onefortieth (or twenty-five thousandths) of an inch. The sleeve D is marked with forty lines to the inch, corresponding to the number of threads on the spindle.
