Designed by Samuel Pook and built by James B. Eads, it saw limited battle and was sunk on the Yazoo River in 1862 by newly developed electronically detonated mines, becoming the first craft ever sunk by this predecessor to torpedo technology. The 175-foot ironclad vessel had 13 guns. The Cairo was sunk within 12 minutes, burying much of its gear and armaments and thus preserving a unique view of the Civil War in the river silt for more than 100 years. The propulsion system is the only known early example of the widely used "western rivers" steamboat engine, characterized by multiple fire-tube boilers with shared steam and mud drums and a two-cylinder noncondensing engine having a small bore, long stroke, and poppet valves. This engine was designed by A. T. Merritt. With a 22-inch bore and 6-foot stroke, it developed about 600 horsepower and drove a sheltered paddlewheel of 22-foot diameter and 15-foot width. The Cairo was raised in 1964 and restored by the National Park Service. It, along with its artifacts, is exhibited at the Vicksburg National Military Park.</p> </div> <div class="field field--name-field-landmark-tags field--type-entity-reference field--label-inline"> <div class="field__label">Tags</div> <div class="field__items"> <div class="field__item"><a href="/category/keyword/uss" hreflang="en">USS</a></div> <div class="field__item"><a href="/category/keyword/cairo" hreflang="en"> Cairo</a></div> <div class="field__item"><a href="/category/keyword/engine" hreflang="en"> Engine</a></div> <div class="field__item"><a href="/category/keyword/boilers" hreflang="en"> Boilers</a></div> <div class="field__item"><a href="/category/keyword/gunboat" hreflang="en"> Gunboat</a></div> <div class="field__item"><a href="/category/keyword/union" hreflang="en"> Union</a></div> <div class="field__item"><a href="/category/keyword/civil-war" hreflang="en"> Civil War</a></div> <div class="field__item"><a href="/category/keyword/mississippi-river" hreflang="en"> Mississippi River</a></div> <div class="field__item"><a href="/category/keyword/pook" hreflang="en"> Pook</a></div> <div class="field__item"><a href="/category/keyword/eads-0" hreflang="en"> Eads</a></div> <div class="field__item"><a href="/category/keyword/yazoo" hreflang="en"> Yazoo</a></div> <div class="field__item"><a href="/category/keyword/vicksburg" hreflang="en"> Vicksburg</a></div> <div class="field__item"><a href="/category/keyword/vicksburg" hreflang="en"> Vicksburg</a></div> </div> </div> <div class="field field--name-field-image-credit field--type-string-long field--label-inline"> <div class="field__label">Image Credit</div> <div class="field__item">Courtesy Flickr/James Case (CC BY 2.0)</div> </div> <div class="field field--name-field-image-caption field--type-string-long field--label-inline"> <div class="field__label">Image Caption</div> <div class="field__item">USS Cairo Engine and Boilers</div> </div> Wed, 25 Jul 2012 07:40:15 +0000 Anonymous 80422 at https://www.inventionandtech.com https://www.inventionandtech.com/content/eads-bridge <span>Eads Bridge</span> <div class="field field--name-field-image-site-img field--type-image field--label-hidden field__item"> <img src="/sites/default/files/styles/landmark_node_/public/landmarks/images/Eads_Bridge.jpg?itok=2LY8Qeqq" width="250" height="166" alt="Eads Bridge" typeof="foaf:Image" /> </div> <span><span lang="" typeof="schema:Person" property="schema:name" datatype=""> (not verified)</span></span> <span>Wed, 07/25/2012 -

Railroads were taking over, and Chicago was rapidly becoming the center of Midwestern commerce. The Eads Bridge was the first major railroad link over the Mississippi, constructed by the city of St. Louis in an attempt to maintain its dominance as a regional commercial hub.</p> <p>The bridge's designer and builder, James Buchanan Eads, faced unbelievable challenges: political and financial wrangles; shipwrecks, ice storms, and tornadoes; and 14 men dead from caisson disease. Seven years and 7 million dollars after construction began, the bridge opened, carrying fifteen 50-ton locomotives loaded with coal, water, and daredevil passengers. The bridge continues to carry traffic across the Mississippi River today.</p> <p><i>Resources</i></p> <ol><li>Howard S.
