&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Single Center Spring Buggy Company&amp;#039;&amp;#039;&amp;#039; was an American carriage and [[automobile]] manufacturer based in [[Evansville, Indiana]]. The Single Center factory manufactured the Zentmobile, Zent, Windsor, Worth, Single Center, Evansville, Simplicity and Traveler automobiles from 1903 to 1910.&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Kimes-USCars3rd}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
The company was founded in 1886 as the &amp;#039;&amp;#039;&amp;#039;Single Center Spring Buggy Company&amp;#039;&amp;#039;&amp;#039;&amp;lt;ref name=&amp;quot;Evansville&amp;quot;&amp;gt;{{Cite web |title=Single Center Spring Buggy Company |url=https://digital.evpl.org/digital/collection/evaphotos/id/250 |access-date=16 October 2021 |website=Evansville Vanderburgh Public Library Digital Archives |language=en}}&amp;lt;/ref&amp;gt; by Willis Copeland with partners Thomas B. Jones and J. O. St. John.&amp;lt;ref name=&amp;quot;Georgano 2000&amp;quot;&amp;gt;{{Cite book |url=https://www.worldcat.org/oclc/45369199 |title=The Beaulieu encyclopedia of the automobile |date=2000 |publisher=Fitzroy Dearborn Publishers |isbn=1-57958-293-1 |editor-last=Georgano |editor-first=Nick |editor-link=G. N. Georgano |location=Chicago |oclc=45369199}}&amp;lt;/ref&amp;gt;  Initially they manufactured springs but expanded into transmissions and carriages. Starting around the turn of the century they began manufacturing automobiles against the wishes of Jones and St. John who subsequently left the company. Single Center continued to build buggys alongside automobiles.&amp;lt;ref name=&amp;quot;Georgano 2000&amp;quot; /&amp;gt;&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 1911 Single Center ended automobile production and subsequently Willis Copeland became Evansville’s first Chevrolet dealer.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Zent (1900-1902), Zentmobile (1903), Zent (1904-1906) ===&lt;br /&gt;
In 1900 at his machine shop in [[Marion, Ohio|Marion,Ohio]], Schuyler W. Zent built his first automobile. It was a gasoline runabout with single-cylinder 8hp engine and single chain drive.  In the two years following, he built and sold four more.  He improved this model and in July 1902 he announced his plans to manufacture commercially. He could not find the financing necessary to do that in Marion, so he journeyed to Evansville, Indiana.  His car was put into production by the Single Center Spring Buggy Company, as the &amp;#039;&amp;#039;&amp;#039;Zentmobile&amp;#039;&amp;#039;&amp;#039; in 1903.&amp;lt;ref&amp;gt;{{Cite book |url=https://books.google.com/books?id=qRrmAAAAMAAJ&amp;amp;q=zentmobile |title=The Horseless Age |date=1903 |publisher=Horseless Age Company |language=en}}&amp;lt;/ref&amp;gt;&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt; &lt;br /&gt;
&lt;br /&gt;
Willis Copeland would manufacture the car, and all Zent had to worry about was selling it. This proved more difficult than Zent had hoped, and within the year the partnership had broken up.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt; &lt;br /&gt;
&lt;br /&gt;
Schuyler Zent returned to Ohio to build a new &amp;#039;&amp;#039;&amp;#039;Zent&amp;#039;&amp;#039;&amp;#039; in [[Bellefontaine, Ohio|Bellefontaine]].  The new Zent was in production in early 1904.  His new Zent was powered by a three-cylinder 18 hp engine mounted under the hood, and featured shaft drive. A twin and a four joined the line in 1906. Early in 1907 the Zent company became the Bellefontaine Automobile Company, and the car’s name was changed to Traveler.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&amp;lt;gallery widths=&amp;quot;280&amp;quot; heights=&amp;quot;200&amp;quot;&amp;gt;&lt;br /&gt;

&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Windsor (1906) ===&lt;br /&gt;
J. A. Windsor incorporated the Windsor Automobile Company in his native Chicago in late 1905. He traveled to Evansville, Indiana to talk to Willis Copeland of the Single Center Buggy Company, who agreed to build the car for him. The &amp;#039;&amp;#039;&amp;#039;Windsor&amp;#039;&amp;#039;&amp;#039; was a four-cylinder 30-hp touring car with shaft drive and a friction-type transmission that Windsor preferred calling a “rolling traction drive.&amp;quot;&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt; The friction drive was designed by Copeland’s factory engineer William O. Worth.&amp;lt;ref&amp;gt;{{Cite book |url=https://books.google.com/books?id=IXEfAQAAMAAJ&amp;amp;q=%22windsor+car%22 |title=The Motor Way |date=1906 |publisher=L.L. Bligh |language=en}}&amp;lt;/ref&amp;gt;&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Windsor had trouble selling his car at his $2,500 ({{Inflation|US|2500|1906|fmt=eq}}) asking price. Unable to establish a viable sales organization, he was out of business within the year.  The car was taken over by Willis Copeland who formed the Evansville Automobile Company and rebranded it as the &amp;#039;&amp;#039;&amp;#039;Simplicity&amp;#039;&amp;#039;&amp;#039;.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&amp;lt;gallery widths=&amp;quot;220&amp;quot; heights=&amp;quot;220&amp;quot;&amp;gt;&lt;br /&gt;

&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Worth (1906-1910) ===&lt;br /&gt;
William O. Worth was an engineer from the earliest days of horseless carriages. He designed the [[drivetrain]] for the &amp;#039;&amp;#039;&amp;#039;Benton Harbor Motocycle&amp;#039;&amp;#039;&amp;#039; built from 1894 to 1896 by the Baushke Bros. in [[Benton Harbor, Michigan]].&amp;lt;ref&amp;gt;{{Cite web |date=2015-03-17 |title=The Benton Harbor Motocycle &amp;amp; The Benton Harbor Motor Carriage Co. |url=http://www.american-automobiles.com/Benton-Harbor.html |archive-url=https://web.archive.org/web/20150317063053/http://www.american-automobiles.com/Benton-Harbor.html |archive-date=2015-03-17  |access-date=2022-11-05 }}&amp;lt;/ref&amp;gt;  In 1906 now a [[New York City]] consulting engineer, Worth was brought to Evansville by Willis Copeland to get some fresh production expertise and help design the &amp;#039;&amp;#039;&amp;#039;Windsor&amp;#039;&amp;#039;&amp;#039;.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
After the Windsor venture quickly failed, Worth designed a high-wheeler which he talked Copeland into building.  It had an air-cooled two-cylinder engine, double chain drive, tiller steering, and the friction transmission used in the Windsor. This friction drive was originally devised by Worth for the &amp;#039;&amp;#039;&amp;#039;Chicago&amp;#039;&amp;#039;&amp;#039; built in the late 1890&amp;#039;s in [[Harvey, Illinois]].&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
When Willis Copeland suggested changes to it, Worth abruptly departed and formed the Worth Motor Car Manufacturing Company.  Copeland would build the car as the &amp;#039;&amp;#039;&amp;#039;Single Center&amp;#039;&amp;#039;&amp;#039;.  After only a few &amp;#039;&amp;#039;&amp;#039;Worth&amp;#039;&amp;#039;&amp;#039; cars were produced in Evansville, Worth moved to [[Kankakee, Illinois|Kankakee]] and after being evicted from the first factory he leased for failing to pay the rent, he found another site in the same city.  In October 1910 he finally declared bankruptcy.  Reportedly, his vice-president disappeared with the last car in the factory and as many leftover parts as could be fit into the back seat.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&amp;lt;ref&amp;gt;{{Cite book |url=https://books.google.com/books?id=oVIfAQAAMAAJ&amp;amp;q=%22Worth+Motor%22 |title=Motor World Wholesale |date=1910 |publisher=Chilton Company |language=en}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Single Center (1906-1908) ===&lt;br /&gt;
From 1900, Single Center Spring Buggy Company built  motorized buggies to order until 1906 when Willis Copeland involved himself with W. O. Worth.  Worth designed  the &amp;#039;&amp;#039;&amp;#039;Worth&amp;#039;&amp;#039;&amp;#039; car and designed for Copeland a bigger chain-drive motorized buggy that was offered for the 1906 model year as the &amp;#039;&amp;#039;&amp;#039;Single Center&amp;#039;&amp;#039;&amp;#039;.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt; &lt;br /&gt;
&lt;br /&gt;
There were two models of the Single Center sold from 1906 to 1908.  The Single Center 12 HP Auto Buggy was a high-wheeler priced at $675 ({{Inflation|US|675|1906|fmt=eq}}), while the Single Center 12/15 HP Roadster was advertised as being &amp;quot;not a buggy but a racy-looking automobile [[Runabout (car)|runabout]]&amp;quot;.&amp;lt;ref&amp;gt;{{Cite book |url=https://books.google.com/books?id=XWj0WAOO3ycC&amp;amp;q=Single+Center+buggy |title=Automobile Trade Journal and Motor Age |date=1907 |publisher=Chilton Company |language=en}}&amp;lt;/ref&amp;gt;  Its top speed was up to {{convert|30|mi/h|km/h|abbr=on}} and priced at $800, {{Inflation|US|800|1906|fmt=eq}}.  Both models were friction-drive, with a flat-twin engine.&amp;lt;ref name=&amp;quot;Evansville&amp;quot; /&amp;gt;&amp;lt;gallery widths=&amp;quot;280&amp;quot; heights=&amp;quot;280&amp;quot;&amp;gt;&lt;br /&gt;

&amp;lt;/gallery&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Simplicity, Evansville, Traveler (1906-1911) ===&lt;br /&gt;
The Windsor Automobile Company failed in 1906 and Willis Copeland formed a new enterprise, the &amp;#039;&amp;#039;&amp;#039;Evansville Automobile Company&amp;#039;&amp;#039;&amp;#039;, which he successfully sold stock to a number of friends in town, including the mayor.  He also set up a proper assembly line for the first time.&amp;lt;ref&amp;gt;{{Cite web |date=2015-03-17 |title=The Simplicity Automobile &amp;amp; The Evansville Automobile Co. |url=http://www.american-automobiles.com/Simplicity.html |archive-url=https://web.archive.org/web/20150317093853/http://www.american-automobiles.com/Simplicity.html |archive-date=2015-03-17  |access-date=2022-11-05 }}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Locally the car was marketed as the &amp;#039;&amp;#039;&amp;#039;Evansville&amp;#039;&amp;#039;&amp;#039;, but as the &amp;#039;&amp;#039;&amp;#039;Simplicity&amp;#039;&amp;#039;&amp;#039; the four-cylinder water-cooled car was offered in a variety of body styles.  Its most distinctive feature was its friction gear transmission which did away with the clanking chains Copeland had disliked in the previous cars.  Unfortunately whenever it rained, it would not move. When finally Copeland discovered the reason for this was moisture in the friction gears, he also discovered that it could be solved by enclosing the gears, which he did.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In January 1909 Willis Copeland organized the &amp;#039;&amp;#039;&amp;#039;Traveler Automobile Company&amp;#039;&amp;#039;&amp;#039; in Evansville for the production of a car to be known as the &amp;#039;&amp;#039;&amp;#039;Traveler&amp;#039;&amp;#039;&amp;#039;.&amp;lt;ref&amp;gt;{{Cite book |url=https://books.google.com/books?id=h0a6AqhQ02AC&amp;amp;q=traveler |title=Horseless Age: The Automobile Trade Magazine |date=1909 |publisher=Horseless Age Company |language=en}}&amp;lt;/ref&amp;gt;  Copeland was already manufacturing the Simplicity, and the Traveler was exactly the same car but with the friction gears enclosed.  Changing the car&amp;#039;s name from Simplicity to Traveler was hoped to be a good public relations move.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The Traveler Automobile Company failed in 1911 and subsequently Copeland became Evansville’s first Chevrolet dealer.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&amp;lt;gallery widths=&amp;quot;280&amp;quot; heights=&amp;quot;200&amp;quot;&amp;gt;&lt;br /&gt;
