I was doing a little research today and located Treen's patent for his internal combustion engines. Thought the group would enjoy it.

Reading through JP’s patent is interesting. Who amongst us knew that these engines were “supercharged?” 😂 What is interesting is when the Model L changed from a rotary valve to the Model M style crank, it lost its supercharging ability.
