Publisher's Synopsis
Excerpt from Handbook for Machine Designers and Draftsmen
Those only who prepare books of the character of this realize the rapidity with which material for them accumulates. The author would not have believed, in advance, that, after an interval of three years, so extensive a revision as the One here presented would be necessary. Ignoring many minor items, some of the following subjects appear in this edition for the first time, others have been rewritten' in the light of additional information and still others have been sufficiently expanded to justify their mention here.
Thrust Bearings; knife-edgebearings; Roller Bearings; The Critical Speed of Shafts; Tandem or Riding and Steel Belts; The Geometrical Progression of Speeds; The Strength of Spur and Herringbone Gears; Chordal Pitch; Gaging Gear Teeth; Cutting Bevel Gears with R'otary Cutters, including Parallel Depth Bevel Gears; Modified Addendum of Bevel Gears; Axial Thrust of Bevel Gears; Skew Bevel Gears; Practice with friction-gears; Worm Gears; Roller Chains; Friction Clutches; Spiral Springs of the Watch-spring Type; The Wire System of Measuring Screw Threads; Sizes, Properties and Strength of Wire; The Capacity of Horizontal Cylindrical Tanks, Full and Partly Full; Weirs, Rectangular and V-notch; Standard Pipe Tables; Pipe Flanges and Fittings; The Measurement of Tapers and Dove tails; Forming and Other Tools; Press Fits, Straight and Taper; Balancing Revolving Parts, including the Technique of Running Balance; The Floating Lever; Velocity and Force Relations in Linkwork; Permissible Cost Of Special Shop Equipment; The Weight of Solids of Revolution; The Diameter of Shell Blanks; The Power Consumed by Drilling Machines; Taylor's Cutting Speeds; Hardness Tests, including the Relation of Brinell and Scleroscope Hardness Numbers to One Another and to the Strength of Steel; Heat Treatment of Steel including the Relations Of the Heat Treatment, the Degree Of Temper and the Physical Propertiesiof Carbon Steels and the Heat' Treatment and Properties of Alloy Steels; Temperature Equivalents of Temper Colors; Materials for Steam Boilers and the Propor tions Of Rivetted Joints; The Discharge Capacity of Safety Valves; The Properties of Superheated Steam; Steam-pipe Coverings; Approximate Beams of Uniform Strength; The Strength Of Columns; Materials and Constructions for Resisting Shock. New tables will be found in many of these additions and also in the last section as follows: Whole and Fractional Inches Reduced to Decimals of a Foot; Lengths Of Circular Arcs; Cutting Speeds and Revolutions; Decimal Equivalents of Prime Number Fractions; Square and Cube Roots Of Binary Fractions, and Chords for Spacing Circles.
