A PRACTICAL WORK-SHOP COMPANION FOR TIN, SHEET-IRON, AND COPPER-PLATE WORKERS. CONTAINING RULES FOR DESCRIBING VARIOUS KINDS OF PATTERNS USED PRACTICAL GEOMETRY; Mensuration of Surfaces and Solids: TABLES OF THE WEIGHTS AND STRENGTHS OF METALS AND DAY USE IN THE WORK-SHOP. By LEROY J. BLINN, MASTER MECHANIC. A NEW, REVISED AND ENLARGED EDITION, PRINTED FROM 170 NEWLY ENGRAVED ILLUSTRATIONS. PHILADELPHIA: HENRY CAREY BAIRD & CO., INDUSTRIAL PUBLISHERS, BOOKSELLERS AND IMPOrters, THE present is a new and thoroughly revised edition of one of the most popular technical books ever published in the United States. It having been found necessary to make a new set of electrotype plates and new engravings -the old ones having been worn out by actual use—it was determined to have the book re-edited and to add to it, in the different departments, new, recent and necessary matter. All of the old illustrations of patterns have been retained, and new ones have been added. The portion treating of metallic alloys and solders has been entirely rewritten, so as to have a more systematic arrangement, and to bring it abreast with the best modern practice in this interesting and important field. In all the other departments new matter has been added, every effort having been made to render the entire work, in the future, if possible even more useful to the Tin, Sheet-Iron and Copper-Plate worker than in the past. Reference to the many subjects treated of will be rendered easy by a very full table of contents and a voluminous index. PHILADELPHIA, April 30, 1891. (iii) |
