BEING MORE SPECIAL IN SCOPE THAN THE FIRST VOLUME, INASMUCH AS IT DEALS WITH THE PECULIAR REQUIREMENTS OF THE VARIOUS ARTS AND MANUFACTURES, AND MORE DETAILED IN ITS EX PLANATIONS BECAUSE OF THE GREATER COM PLEXITY OF THE MACHINERY SELECTED FOR ILLUSTRATION. WITH A CHAPTER ON RADIO TELEGRAPHY AND TELEPHONY AND Including an Explanatory Chapter on the Leading Conceptions of Perpetual Motion Existing During the Past Three Centuries BY GARDNER D. HISCOX, M.

WBT 45TU STREET 1923 OOPYMOHTBD, 1023, 1917, 1914, 1910 AND 1004, tiv THE NOftMAN W. HENLEY PUBLISHING COMPANY ALHO KNTBRJCD AT STATIONBIW HALI Corsr, LONDON, AH Ki HUNTED IN U. S. A, Preface, THE many editions through which the first volume of Mechanical Movements has passed is more than a suffi cient encouragement to warrant the publication of a second volume, more special in scope than the first, inasmuch as it deals with the peculiar requirements of various arts and manu factures, and more detailed in its explanations, because of the greater complexity of the machinery selected for illustration. Despite the greater simplicity of the devices which have been pictured and briefly explained in the first volume, the appli ances described in this second volume can be just as easily understood, the text having been so worded that no insuper abledifficulties are presented to the reader of average mechani cal knowledge. More extensive though it may be than Mechanical Movements, the present work by no means ex hausts the subject, Many an apparatus has been omitted, either because limitations of space have intervened, or because of the impossibility of securing adequate details of construc tion. The machines incorporated, however, cover so vast a mechanical field and have been so carefully selected to supply the needs of the student seeking general information, that they will 1 0 found fairly representative of the power devices used in old and modern industries. Mechanical intelligence may well be deemed to have found its highest expression in the con trivances that are illustrated and described in these pages. Although the author has not the slightest desire to encour age the hopeless pursuit of perpetual motion, he has, neverthe less, thought it advisable to dwell at some length on the exceed ingly ingenious means devised by misguided inventors in their endeavors to solve an unsolvable problem. The pages in which perpetual motion machines are described may induce those who still believe in reaching this ignis fatnits to bend their energies in causes more worthy of their xeal. Moreover, it may be that some of the mechanical movements which have been evolved by the perpetual motion inventor, although they may not attain the end sought by him, may still be applied with profit to his instruction in true mechanical principles and to avoid the errors committed in the search on the lines of this folly of past centuries. This in itself is a sufficient justification of the insertion in this volume of the seel ion on perpetual motion. Thedeeper we delve in the research for novelty and variety in the present field of mechanical design, the more we see the possibilities of human ingenuity. The facility and power of construction shown in the complicated mechanism of the past augur well for the future of inventive genius. GARHNKK I. Hxscox. CONTENTS. SECTION L MECHANICAL POWER LEVER.
