THE author was led to undertake the present work on Turning and Mechanical Manipulation, from the circumstance of there being no general treatise in the English language for the guidance of the Amateur in these pursuits. The original works by Plumier and Bergeron, although they were suited to the periods at which they were produced, are neither of them sufficient to convey instruction adequate to the present state of the Art; and the more recent French works leave unnoticed a large portion of the machines and instruments now used by Amateurs. The greatest difficulty the author has encountered in his task, has been that of selection and arrangement; so as to produce, from materials so numerous and dissimilar, a work of general reference and practical instruction, at once sufficiently copious and accessible. But he hopes this difficulty has been satisfactorily met, by the division of the work into five volumes, upon parts of the subject which are broadly distinguished, and which thereby render the volumes in a great measure independent of each other. This plan is also carried out in the subdivision of the volumes into chapters, which may be considered severally to include all that was deemed necessary to be stated upon the respective subjects; or to be, so far as they extend, distinct treatises; and which, in cases of doubt, he has not hesitated to submit to various practical friends for confirmation or extension. These appeals have been answered with an alacrity which calls for his warmest thanks; and the author gladly avails himself of this opportunity of acknowledging these services, which have given a great additional value to his labours. The work being of a technical nature, the author hopes to escape literary criticism, his main object having been to treat each subject in clear and concise language. As, however, notwithstanding his utmost care, he cannot expect to have been so fortunate as entirely to have escaped errors, ambiguities, or omissions, he requests of his readers the favor of the communication of any such defects, in order that those of most material import may be noticed in the Appendix to the second and ensuing volume, a great part of which is already completed. CHARING CROSS, January 1, 1843. MATERIALS, THEIR DIFFERENCES, CHOICE, AND PREPARATION; VARIOUS MODES OF WORKING THEM, GENERALLY WITHOUT CUTTING TOOLS. Introduction.-Materials from the Vegetable, the Animal, and the Mineral Kingdoms.-Their uses in the Mechanical Arts depend on their structural differences, and physical characters. The modes of severally preparing, working, and joining the materials, with the practical description of a variety of Processes, which do not, generally, require the use of Tools with cutting edges. VOL. II. THE PRINCIPLES OF CONSTRUCTION, AND PURPOSES, OF CUTTING TOOLS; The principles and descriptions of Cutting Tools generally-namely, Chisels and Planes, Turning VOL. III. THE PRINCIPLES AND PRACTICE OF HAND OR SIMPLE TURNING.. Descriptions of various Lathes ;-applications of numerous Chucks, or apparatus for fixing works in the Lathe. Elementary instructions in turning the soft and hard woods, ivory and metals, and also in Screw-cutting, with numerous Practical Examples; some plain and simple, others difficult and complex, to show how much may be done with hand tools alone. VOL. IV. THE PRINCIPLES AND PRACTICE OF ORNAMENTAL OR COMPLEX TURNING. Sliding Rest with fixed tools-Revolving Cutters, used in the Sliding Rest, with the Division Plate and Overhead Motion. Various kinds of Eccentric, Oval, Spherical, Right-line and other Chucks. Ibbetson's Geometric Chuck. The Rose Engine, and analogous contrivances, &c. With numerous Practical Examples. VOL. V. THE PRINCIPLES AND PRACTICE OF AMATEUR ENGINEERING. Lathes with sliding Rests for metal turning, Self-acting and Screw-cutting Lathes-Drilling Machines -Planing Engines-Key-groove, Slotting and Paring Machines-Wheel cutting and Shaping Engines, &c. With numerous Practical Examples. Vols. I. and II. alone, will constitute a smaller yet complete work, which may be extended by the addition of either one or the whole of the other volumes, as each will be complete in itself. |
