ERECTING AND OPERATING $3

——JUST ISSUED——

ROGERS’ ERECTING and OPERATING
_for_ _ENGINEERS, MACHINISTS AND MILLWRIGHTS_

AUDEL]

A PRACTICAL HANDBOOK on Excavations, Foundations, Structures, Millwrighting, Shafting, Belting, Piping, Boilers, Engines, Installing Machinery, etc.

In order to become an expert at the _erection and operation of modern machinery and appliances_, judgment must be added to execution; now as judgment cannot be taught in writing, further than in laying down certain principles of procedure, therefore the book is largely personal.

The method of instruction followed is to deal with the various subjects mentioned, each consisting of nearly the same number of pages and illustrations, indicating the course of study.

Working Drawings, Foundations, Excavating, Piling and Grillage, Brick Work, Concrete, Reinforced Concrete, Millwright’s Tools, Steel Square and its uses, Bridge Work, Structures, Scaffolding and Stagging, Rigging Knots. Hitches and Splices, Chains and Tackle, Steel Structure Work, Roofing, Blacksmithing. Tool Dressing, Belting and Pulleys, Shafting Lining, Speeds, Piping and Joints, Plumbing, Steam Boilers and Accessories, Chimneys, Drafts, Steam Engine Operation, Engine Foundations. Valve Setting, Water Power Installations, Steam Turbines, Pumping Machinery, Electrical Installations, Motors, Wiring, etc., Refrigerating Systems, Rules, Receipts, Metallic Compositions, Useful Tables. Ready Reference Index.

By following this plan, and with the aid of the ready reference index to be found at the end of the volume, the work becomes a reference book, as well as a course of systematic study in Mill Engineering.

This volume is convenient in size, handsomely and durably bound in black cloth, having gold edges and titles; containing 600 pages, illustrated by over 500 drawings and illustrations of practical work. It is in every way a generously good book both in contents and manufacture.

=+PRICE+= $3 =+to any address+=.

ADVANCED MACHINIST $2

THE trade of the machinist is peculiar in that it is a preparation for so many positions outside of it.

It takes a man of good natural ability and of considerable education—not always from books—to make a first-class machinist; so that when one is well qualified he is also prepared for many other openings.

The aim of this work is to point the way of advancement to those who become fitted to assume these responsibilities and rewards.

The advanced machinist is a work of sterling merit, a few of the hundreds of subjects are here named, but they in no way show the scope of this work, which must be seen to be appreciated:

A Course in Machine Shop Mathematics; Various Measuring Instruments and Their Uses; Screw Cutting; Boring; Milling; Drilling; Grinding; Punching and Shearing; Bolt Cutting Machinery; Special and Auxiliary Machines; Shop Management: Work Shop Receipts and Devices, etc., etc.

The personal character of the book appeals to all in any way
associated in the machinery and allied trades.

AUDEL]

This book is a companion volume to Progressive Machinist and is uniform in binding and style, but more advanced in the subject of Machine Shop Practice, containing about the same number of pages, illustrations, etc.

PRICE, $2, Postpaid.
