			<content:encoded><![CDATA[<p>Drinking straws have a history. A long one. Natural straws were used by beer-drinking Sumerians 5000-700 years ago as filters for solid particulate byproducts of fermentation. The grass-stem straw reigned until 120 years ago this month, when Marvin Stone patented a process for manufacturing spiral-wound tubes.</p>

<p><img src="http://perpenduum.com/wp-content/uploads/2008/01/375962-stone.png" alt="Artificial straw mold" border="0" width="450" height="352" class="center"/><span class="caption">Marvin C. Stone, US Patent No. 375692</span></p>

<p>The material was paper, with a small amount of adhesive at one end that secured the straw around the mold, initially a pencil. The straw was then removed from the mold and dipped in paraffin; this hermetically sealed and further strengthened the straw.</p>

<p>Stone didn&#8217;t rest with one advancement in straw technology. In 1896 he patented a new design for artificial straws, one that more closely resembled the natural straw in bore size, and it&#8217;s double-bore design is reminiscent of today&#8217;s hot straws.</p>

<p><img src="http://perpenduum.com/wp-content/uploads/2008/01/585058-stone.png" alt="Fig 1-4: Double-bore artificial straw" border="0" width="287" height="386" class="center" /><span class="caption">Marvin C. Stone, US Patent No. 585058</span></p>

<p>Although details are sketchy, Stone Straw Company (now <a href="http://www.stonestraw.com">Stone Straw, Ltd</a>) was founded around the turn of the 20th century. In 1906, the company invented a machine that automated the the manufacture of spiral-wound straws. (Figure below is from a 1916 filing.)</p>

<p><img src="http://perpenduum.com/wp-content/uploads/2008/01/1252284-maltby.png" alt="Machine for manufacturing spirally-wound straws" border="0" width="500" height="401" class="center"/><span class="caption">Lewis C. Maltby, US Patent No. 1252284</span></p>

<p>In 1940, Stone Straw Co. was still using the same spirally-wound manufacturing process invented 50 years earlier. There was some technological progress, such as the angularly-bent straw, replacing the relatively unsanitary and cut-inducing glass tubes used in soda fountains, but it&#8217;s clear that the basic straw-creation process was essentially unchanged.</p>

<p>Stay tuned for Part 2.</p>
