This paper examines the manual processes that led to the first patents for wire nailmaking machines. It introduces a recent discovery, backed by provenance and analysis, dating the first proper wire nail machine to 1816, thereby putting the clock back some 30 years over conventional chronology. It shows how the assemblages, hence much of the technology that we enjoy today, are pre-eminently French, and dispels some of the myths that have accumulated in the accepted literature concerning wire nails. The paper is based on research into the original patent dossiers from 1808 to 1825 held in Paris. As part of this analysis, errors relating to the so-called wire nail-making machine of James White of 1810 are identified. The paper shows how early reporting had distorted the inventor's own claims.

Design and Fabrication of a Continuous Polishing Machine
Veerakumar Muthirulan
Journal Européen des Systèmes Automatisés
Polishing is a surface machining technique to produce a high-quality finished surface on the product. It is a multistage process, in which each subsequent stage uses a finer abrasive. This paper aims to design and fabricate a polishing machine that performs polishing stages continuously, eliminating the idle time in the polishing process. The designed machine consists of four spindle heads, each of which carries a unique flap wheel. The flap wheels can raise or lower according to the size of the workpiece to be polished. Three types of rollers were adopted in the machine: a mild steel roller coated with heat resistant rubber, a hylam roller and a nylon roller. A pneumatic clamping system was placed at the feeder to fix and hold the workpiece. In addition, the compressor pressure is regulated by a pressure regulator. A prototype of the polishing machine was fabricated according to the design, and used to polish several types of workpieces. The results show that this machine can polish stainless-steel flat bars, square tubes and rectangular tubes into 10mm-150mm width products, operate at a high speed of 2,000~3,000 rpm, and, most importantly, execute multiple polishing operations continuously. The proposed polishing machine is helpful to the automation of the polishing industry.
