Wow, thanks for posting another weird wonder! It does not show the cam drive ratio, nor where the ports lead to, however; I imagine it is a 4 stroke [as there is no separate induction chamber] with possibly an atmospheric inlet valve [not shown] OR; There could be 2 piston-valves per cylinder [not shown] if no atmospheric inlet were used!? Either way; there would be considerable combustion forces bearing down on the piston-valve/s. The third pin in the intermediate valve rod is staying still as though a pivot point, this would share half of the combustion pressure with the cam, it would seem. "24Hp & up" wow; i imagine that's at least a twin. Has anyone got a pic of one, or known of one?? |

Given that these were a west coast design and used mainly in salt water, it's not surprising there is only one known survivor: in the Vancouver Maritime Museum. Probably an engine used on lakes or only in the Fraser river. Thanks for posting that Richard. What magazine is the advert from? |
