Ellen Louise Demorest
Ellen Louise Demorest (''née'' Curtis, November 15, 1824 – August 10, 1898) was an American businesswoman, fashion arbiter and Hatmaking, milliner, widely credited for inventing mass-produced tissue-paper pattern (sewing), dressmaking patterns. With her husband, William Jennings Demorest, she established a company to sell the patterns, which were adaptations of the latest French fashions, and a magazine to promote them in 1860. Her dressmaking patterns made French styles accessible to ordinary women, thus greatly influencing US fashion. Early life Demorest was born November 15, 1824, in Schuylerville, New York. She was the second of eight children born to Electra Abel Curtis and Henry D. Curtis. Her father was a farmer and the owner of a men's hat factory. At eighteen, Demorest set up a millinery shop in Saratoga Springs, New York, Saratoga Springs with the help of her father. After a year, she moved her business to Troy, New York, Troy before relocating again to Williamsb ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sewing Machine
Diagram of a modern sewing machine Animation of a modern sewing machine as it stitches A sewing machine is a machine used to sew fabric and materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry. Home sewing machines are designed for one person to sew individual items while using a single stitch type at a time. In a modern sewing machine, the process of stitching has been automated, so that the fabric easily glides in and out of the machine. Early sewing machines were powered by either constantly turning a flywheel handle or with a foot-operated treadle mechanism. Electrically-powered machines were later introduced. Industria ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Straight-eight Engine
The straight-eight engine or inline-eight engine (often abbreviated as I8) is an eight-cylinder internal combustion engine with all eight cylinders mounted in a straight line along the crankcase. The type has been produced in side-valve, IOE, overhead-valve, sleeve-valve, and overhead-cam configurations. A straight-eight can be timed for inherent primary and secondary balance, with no unbalanced primary or secondary forces or moments. However, crankshaft torsional vibration, present to some degree in all engines, is sufficient to require the use of a harmonic damper at the accessory end of the crankshaft. Without such damping, fatigue cracking near the rear main bearing journal may occur, leading to engine failure. Although an inline six-cylinder engine can also be timed for inherent primary and secondary balance, a straight-eight develops more power strokes per revolution and, as a result, will run more smoothly under load than an inline six. Also, due to the eve ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cord (automobile)
Cord was a brand of American luxury automobile manufactured by the Auburn Automobile Company of Connersville, Indiana, from 1929 to 1932 and again in 1936 and 1937. Auburn was wholly owned by the Cord Corporation, founded and run by E. L. Cord as a holding company for his many transportation interests (which included the Lycoming engines, Stinson aircraft, and Checker Motors). Cord was noted for its innovative technology and streamlined designs. Innovations Cord innovations include front-wheel drive on the L-29 and hidden headlamps on the 810 and 812. Though DeSoto used them in 1942, hidden headlamps did not reappear as a luxury feature until the 1960s, beginning with the 1963 Chevrolet Corvette. It was followed two years later by another General Motors product, the Buick Riviera, whose GM stylists later stated they were trying to capture the "feel" of the Cord's design. "Servo" shifting was accomplished through a Bendix electro-vacuum pre-selector mechanism (a type o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Velie
Velie was a brass era United States, American automobile brand produced by the Velie Motors Corporation in Moline, Illinois from 1908 to 1928. The company was founded by and named for Willard Lamb Velie, Willard Velie, a maternal grandson of John Deere (inventor), John Deere. Velie founded Velie Carriage Company in 1902, which was successful, then Velie Motor Vehicle Company in 1908. History Velie ads bragged they "produce every important part" and were not simply assemblers, a lesson Ford Motor Company, Ford had taught. However, Velie's first car was assembled with many components purchased from outside suppliers.Vance, p.E10. By 1910, Velie had sold more than 1000 cars. In 1911 Velie introduced a truck line, and began making a proprietary four-cylinder engine, although some parts came from suppliers.
