About this title

Application for patent filed February 21 1958; patent granted March 8 1960.

"This invention relates to model internal-combustion engines, and more particularly to an improved spring-actuated starter for such engines, especially as employed for operating small scale models of airplanes, boats, automobiles and similar toys. In my earlier Patent I broadly disclose a self-releasing spring starter which stores energy when the drive shaft is rotated in a reverse or contra-normal direction as part of the starting operation. The present invention incorporates improved means whereby the starting mechanism automatically engages and disengages itself as required."

De Groat assigned the rights in this patent to Leroy (Roy) Cox's Cox Manufacturing Co. Known as the Cox Spring Starter, this product is one of the simplest ways to include a self-starter mechanism in small engines; it went on to become one of Cox's most distinctive gadgets.
