In this companion to American Levels and Their Makers, Vol. I, the author presents that great rarity a book on patents that both illustrates the patents (in a size large enough to be useful) and explains them. Two hundred and ten level patents are pictured and explained here, with explanations keyed to the patent drawings. They illustrate the major and continuing contributions by L.L. Davis, Justus Traut, the Stratton Bros., and L.S. Starrett, among others. To aid in identification, each patent is triply indexed: by date, patentee, and category (e.g., inclinometer, sighting level, adjustment mechanism, etc.). In addition, the book provides a brief history of the men who obtained the patents, information on whether, when, and how the patents were used, the progression of improvements in patent concepts over time, and information that may be useful in identifying mystery levels. This volume, relating patents to real tools, will prove an invaluable reference for tool collectors and dealers, as well as for students of industrial technology.

A wonderful book that covers the vast range of axes used throughout time and throughout the world, starting with the early stone hand-axes of the paleolithic period through the flint, copper, and bronze axes of early civilizations, the early iron axes of the medieval ages, and the production of steel axes made possible by the Industrial Revolution. Included are discussions of all axe types from celts to hand axes, tomahawks to hatchets, pebble tools to broad axes, plus a chapter on special axes. The author gives detailed descriptions of the axes, how they were made and the materials used, and the evolution of their design over time. Accompanying the descriptions are over 100 photographs of the axes, many seen only in museums. The axe was one of man''s earliest tools, and remained one of his most important almost until the present day. Yet over the tens of thousands of years of its use, the changes in its design have been surprisingly small. What have changed dramatically are its methods and materials of fabrication, reflecting the advances in man''s technological skills. Students of the history of technology and tool collectors alike will find this a fascinating boo

Here, for the first time, is a guide to four of the major woodworking machinery manufacturers: Fay & Egan, Yates-American, Defiance, and Oliver. Leaders in their field throughout the world, their products were used in all walks of life from lumber mills to furniture factories, from schools to arsenals, from shipyards to bakeries. The author''s extensive original research has provided us with a history of each manufacturer, as well as a description of the evolution of its product lines over the years. Accompanying these fascinating histories are numerous beautiful illustrations reflecting each company''s range of products, along with specifications and descriptions, taken from the catalogs of the period. In addition, the book provides invaluable information to collectors and users on buying and restoring old machines. These chapters cover everything from establishing the age and value of an old machine to how to move a piece of heavy woodworking equipment. Special attention is paid to the issues involved in repairing specific kinds of machines. Not only will collectors and users of vintage woodworking machinery prize this book but, as well, those who are simply interested in industrial history and who don''t want this marvelous technology to be lost.

Kan det holde? Hvis din nye og dyre kontorstol går i stykker efter, at du har siddet i den få gange, ville du så købe den samme stol igen, og endda anbefale den til andre? Ved at anvende statik, styrke- og materialelære, når man konstruerer eller ombygger en konstruktion, kan man dimensionere den, så den kan holde til de forventede belastninger, der opstår når produktet anvendes.Denne bog er den første af tre lærebøger indenfor faget konstruktion. Trilogien er tiltænkt ingeniører, maskinmestre, produktudviklere, arkitekter, konstruktører, designere, håndværkere, HTX-studerende og andre, der beskæftiger sig med konstruktioner.Bogen gennemgår teorien for den grundlæggende statik som kræfter, lasttyper, understøtninger, momenter, simple bjælkekonstruktioner og ligevægt. I afsnittet om simple bjælkekonstruktioner beregnes de ydre kræfter først med den klassiske metode, og afsluttes med to nye hurtigmetoder, der på få sekunder kan bestemme reaktionerne.I slutningen af bogen vil der være øvelser i at omsætte fysiske produkter til statiske modeller, samt en case, hvor reaktionerne skal bestemmes.Om forfatterenKim Kjærsgaard er uddannet håndværker i Flyvevåbnet og ingeniør fra Aalborg Universitet i Esbjerg.Har siden 2015 arbejdet som underviser på Produktionsteknologuddannelsen på KEA - Københavns Erhvervsakademi.Samt er CEO hos VAXA Consulting.Læs mere om statikbogen på www.kandetholde.dk/statikLæs mere om trilogien på www.kandetholde.dk/bøger
