Conveyors and Cranes [antikvár]

PREFACE # This amply-illustrated work reflects a lengthy experience in the design and application of conveying machinery and cranes. It wiil be found easy to read and of practieal interest. It is not in the nature of a catalogue, but is a teehnical treatise embraeing as mueh of the topics treated as is feasible in a book of moderate size and not too sketchv in eharacter.. The first part deals, in considerable detail, with the mechanical handling of goods in package form (including bags, baskets, and boxes) by means of eonveyors, elevators, and staekers. The second part gives full consideration to those types of machines employed for handling eoal and other loose materials in bulk. Both mechanical and pneumatie grain-handling plants are dealt with at somé length. The third part is devoted to a briefer treatment of several important classes of cranes; as used in heavy workshops, in shipbuilding yards, on dock quays, and in railway goods yards. Ship hoists and eleetric telphers alsó receive attention. Although the book is mainly descriptive, yet it contains many tables and graphs, alsó capacity and power formuláé, and worked examples relating to all kinds of eonveyors. It will, therefore, be of service to draughtsmen engaged on design work, as well as to factory engineers and others responsible for the seleetion and application of eonveyors in connexion with a variety of large scale industries. These include motor car factories, breweries, cement works, chemical works, foundries, gasworks, granaries, mines, power stations, and sugár refineries. Parts of somé chapters have been based on my papers read before several engineering societies, and on various articles contributed to Cassier's Mechanical Handling. My grateful thanks are alsó due to several firms named in the text for their help in the shape of drawings, photographs, and data. Further information on the wide subject of the lifting and shifting of materials and goods may be derived from my two larger books and the references given therein. W. H. ATHERTON. Derby,
