Page 328 - Government in 1866. The three principal units are the meter, the unit of length, the liter, the unit of capacity, and the gram, the unit of weight. Multiples of these are. obtained by prefixing the Greek words: deka (10), hekto (100) , and kilo (1000). Divisions are obtained by prefixing the i.atiu words: deci d'à), centi (гДи)
Page 450 - The module is the pitch diameter in millimeters divided by the number of teeth in the gear. Pin Gear — Gear with teeth formed by pins such as the old lantern pinion. Also formed by short projecting pins or knobs and only used now in some feeding devices. Quill Gears — Gears or pinions cut on a quill or sleeve. Skew Gears — See Helical. Spiral Gears — (Fig.

Page 39 - D is the actual external diameter 71 of the tube throughout its parallel length, and is expressed in inches. Further back, beyond the perfect threads, come two having the same taper at the bottom, but imperfect at the top. The remaining imperfect portion of the screw-thread, furthest back from the extremity of the tube, is not essential in any way to this system of joint ; and its imperfection is simply incidental to the process of cutting the thread at a single operation. From the foregoing it follows...

Page 431 - The strip of sheet metal is fed under the stripper and is prevented by that member from lifting with the punch upon the up-stroke, following the punching out of the blank. Where several punches are combined in one hole for blanking as many pieces simultaneously, they are known as multiple blanking tools.
Page 27 - Thus, by measuring one-half of the depth of the thread from the top on each side, the diameter of the thread, as indicated by the caliper, or the pitch diameter, is the full size of the thread less the depth of one thread, as follows : — This depth may be found Depth of Whitworth standard threads = 0-64 -*- number of threads to I inch.
