Agrippina (1827)
''Agrippina'' was a steamboat designed for the Middle Rhine. On delivery she was found to be too heavy, and was returned to her builder NSM, which tried to use her as a freighter on the Lower Rhine. When this failed too, ''Agrippina''s engines were used to create the compound steam engine of the tugboat , creating the first effective compound steam engines. In 1829 ''Agrippina'' was the first towed dumb barge on the Rhine. After a rebuilt, she became the first steamboat to tow an iron barge on the Rhine in 1841. Context Preußisch-Rheinische Dampfschiffahrts-Gesellschaft (PRDG) In October 1825 the Preußisch-Rheinische Dampfschiffahrts-Gesellschaft (PRDG) ordered two steamboats at the Nederlandsche Stoomboot Maatschappij (Dutch Steamboat Comp.) A later overview suggests that ''Agrippina'' was part of this initial order by the PRDG. It also showed that she was comparatively large for a steamboat. Already in 1828, PRDG's plan was to use ''Agrippina'' as the third boat between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agrippina The Younger
Julia Agrippina (6 November AD 15 – 23 March AD 59), also referred to as Agrippina the Younger, was Roman empress from 49 to 54 AD, the fourth wife and niece of Emperor Claudius. Agrippina was one of the most prominent women in the Julio-Claudian dynasty. She was the daughter of the Roman general Germanicus and Agrippina the Elder, granddaughter of Augustus (the first Roman emperor). Her father, Germanicus, was the nephew and heir apparent of the second emperor, Tiberius. Agrippina's brother Caligula became emperor in 37 AD. After Caligula was assassinated in 41 AD, Germanicus' brother Claudius took the throne. Agrippina married Claudius in 49 AD. Agrippina functioned as a behind-the-scenes advisor in the affairs of the Roman state via powerful political ties. She maneuvered her son Nero into the line of succession. Claudius became aware of her plotting, but died in 54; it was rumoured that Agrippina poisoned him.Tacitus, ''Annals'' XII.66; Cassius Dio, ''Roman History'' LXI.3 ...

Concordia (1826)
''Concordia'' was the first German steamboat on the Rhine. On 1 May 1827 she made her first trip from Mainz to Köln. Context In 1825 the Dampfschiffahrts-Gesellschaft von Rhein und Main (DGRM) was founded in Mainz. It ordered three ships at the Nederlandsche Stoomboot Maatschappij (Dutch Steamboat Comp.), with which it cooperated. ''Concordia'' was meant to steam between Mainz and Mannheim, ''Ludwig'' from Mannheim to Kehl and Strasbourg, and ''Stadt Frankfurt'' would steam between and between Mainz and Frankfurt am Main. The order for the ships was part of a plan by three companies to cooperate and monopolize steam transport on the Rhine. The idea was that the Nederlandsche Stoomboot Maatschappij would offer transport between Rotterdam and Cologne. The Preußisch Rheinische Dampfschiffahrts-Gesellschaft“ (PRDG) would steam from Cologne to Mainz. Finally the DGRM would service the Upper Rhine.

Deutz, Cologne
The Cologne borough of Deutz (german: Köln-Deutz ; ), is a part of central Cologne, Germany, and was once an independent town. History Deutz was established under Roman Emperor Constantine I in 310 AD, when he established ''Castrum Divitia'', a military camp built on the banks of the Rhine across from Colonia Claudia Ara Agrippinensium. Camp and city were linked via a bridge from the same time. During the Middle Ages, Deutz was an important centre of learning in medieval Germany. Up into the early Middle Ages it was known by the Latin name ''Divitia'', from the 10th century as ''Tuitium''. It was located on the right bank of the Rhine, opposite Cologne, which grew up on the left bank.

Argand Lamp
The Argand lamp is a type of oil lamp invented in 1780 by Aimé Argand. Its output is 6 to 10 candelas, brighter than that of earlier lamps. Its more complete combustion of the candle wick and oil than in other lamps required much less frequent trimming of the wick. In France, the lamp is called "Quinquet", after Antoine-Arnoult Quinquet, a pharmacist in Paris, who used the idea originated by Argand and popularized it in France. Quinquet sometimes is credited with the addition of the glass chimney to the lamp. Design The Argand lamp had a sleeve-shaped wick mounted so that air can pass both through the center of the wick and also around the outside of the wick before being drawn into a cylindrical chimney which steadies the flame and improves the flow of air. Early models used ground glass which was sometimes tinted around the wick. An Argand lamp used whale oil, seal oil, colza, olive oil or other vegetable oil as fuel which was supplied by a gravity feed from a reservoir mou ...

Pulley
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain. The earliest evidence of pulleys dates back to Ancient Egypt in the Twelfth Dynasty (1991-1802 BCE) and Mesopotamia in the early 2nd millennium BCE. In Roman Egypt, Hero of Alexandria (c. 10-70 CE) identified the pulley as one of six simple machines used to lift weights. Pulleys are assembled to form a block and tackle in order to provide mechanical advantage to apply large forces. Pulleys are ...

Spur
A spur is a metal tool designed to be worn in pairs on the heels of riding boots for the purpose of directing a horse or other animal to move forward or laterally while riding. It is usually used to refine the riding aids (commands) and to back up the natural aids (the leg, seat, hands, and voice). The spur is used in many equestrian disciplines. Most equestrian organizations have rules in about spur design and use and penalties for using spurs in any manner that constitutes animal abuse. Etymology This very old word derives from Anglo-Saxon ''spura, spora'', related to ''spornan, spurnan'', to kick, ''spurn''; cf. Medieval High German ''Sporn'', modern German ''Sporn'', Dutch ''spoor''. The generalized sense of "anything that urges on, stimulus" is recorded in English from'' circa'' 1390. Design The parts of a spur include: *The "yoke", "branch", or "heel band", which wraps around the heel of the boot. *The "shank" or "neck", which extends from the back of the yoke and is the ...
