1926 Took out his first patent on tensioning devices, followed by more than 20 others in the same area.
"Many of Weller's inventions and patent applications relate to automatic tensioning and guiding devices of warp knuckles. Since the end of the 1920s, better and cheaper-to-produce drives of overhead camshafts for four-stroke engines were sought in automotive engineering. The so-called Weller drive is a constructive solution in which, using Weller's patents, a spur-gear drive is combined with a warp drive. This solution was taken up by AJS in 1927 to replace a king shaft drive from a motorcycle motor and in 1932 by Hermann Reeb with the newly designed engine of the Horex S 600."
