PREFACE ! qall The publishers have endeavored in this MachineShop Handbook to compile such information as will be of value to persons engaged in shop work. For the greatest convenience of the user, it has been made a reference book of small size, but containing a vast amount of information needed by the mechanic. A special feature is the system of indexing. Every important item is indexed under all the letters in which it is likely to be sought, thus making it easy to find the information on any subject. A very large number of illustrations are used. These are of the standard I.C.S. quality as prepared by our special staff of artists.

The following subjects are treated : Useful tables and rules; shop work; and first aid to the injured.

The useful tables and rules cover weights and measures, mensuration, trigonometry, and properties of materials. Shop work covers drilling, reaming, tapping and threading, lathe work, threads and thread cutting, measuring and testing, millingmachine work, indexing, helixes and spirals, key work, gearing, planer work, shaper work, slotter work, broaching, grinding and polishing and lapping, jigs and fixtures, punch and press work, die casting, gauges, micrometers and vernier instruments, lubricants, temperature indicators, metals, heat treatment, chilled iron, welding and brazing and soldering, coating and protecting, filing, stock estimating, chipping, riveting, pipe bending, laying out work, blueprints, belting, pulleys and shafting, knots and hitches, springs and miscellaneous shop hints. First aid to the injured covers the equipment needed for attending to injuries, the nature of the injuries that have been the most common, detailed instruction for resuscitation, and the care of the patient.
