<p>[QUOTE=&quot;Drusus, post: 176899, member: 6370&quot;]Then by 1817 you have the Uhlhorns knuckle press that worked on a lever priniciple the mechanism carrying the upper die consisted of 3 links known as the &#039;sway lever&#039; the &#039;column&#039; and the &#039;hammer lever&#039; and the die was fixed to the underside of the last. Both feed motion for the blanks and ejection motion for the struck coins. The operator had to run a flywheel up to sufficent speed and engage a clutch:</p><p>&nbsp;</p><p><img src="http://www.tribalsoup.com/mint/knucklepress.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>Uhlhorns Knuckle Press</p><p>&nbsp;</p><p><img src="http://www.tribalsoup.com/mint/knuckle.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>Thonnelier&#039;s Knuckle Press</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Then there is the Boulton&#039;s steam engine driven automatic coining press. </p><p>&nbsp;</p><p>&nbsp;</p><p><img src="http://www.tribalsoup.com/mint/boultons.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>&nbsp;</p><p>and then of course you have the sophisticated automated machines used today.[/QUOTE]</p><p><br /></p>
