    What is the name of this type of engine.

    I've looked on the net and the nearest I can find is Comber - but I don't think that's it.
    I'm busy making something along these lines and will post plans etc. when completed.
    But I'd like to get the name right.
    Regards, Ken

    I have no idea of the name but it is neat and would make Rube Goldberg proud.

    Not a comber, where the cylinder spins completely. This looks like one of the multiplicity of oscillators.

    Bill Reichart describes his design as a Gyro Engine.
    https://www.billreichart.com/gyro-engine
    The plans were modified by Ernie Weinberg and he calls his simply Ernie's Easi-Spin.

    O.K. - This is what I'm building :-
    gyro.jpg
    The cylinder rotates within the main flywheel (on a different centre) it is 16mm bore x 30mm stroke.
    The main flywheel rotates in a cradle of ball bearings and held into that cradle by a pair of inclined ball bearings - running at 45° - the middle of the flywheel is thence a void.
    There is a smaller auxiliary takeoff flywheel running on the cylinder axle.
    kvom - the cylinder spins completely - it's not an oscillator.
    The drawing is horribly busy with all the details on - I'll post more as it progresses.

    I'm about half way through the build - but I still need a name for it. Any suggestions ?

    Regards, Ken

    Here's the primary flywheel - machined from a CI castor wheel - Brass piston rod clevis is mounted.

    fcheslop - thanks for the link - useful.
    O.K. So a "Box Of Frogs Rotary Cylinder Engine" it is !
    Good luck with the Ringbom.
    I just recently completed the Jonkman 60 Stirling
    Jonkman60.jpg
    Here it is standing next to my elbow engine.
    I like it because I can run it on the bar - I modified the burner to run on alcohol.
    Regards, Ken

    Hi Ken, good luck with the build
    Im basing the Ringbom on one Iv already made designed by Renee Schaffer the spelling maybe wrong but you can see it here. Iv also recieved some info from Huib Vissor so with a bit of luck it should run this time

    I've seem videos of similar engines. I believe it's a type of oscilator that would have been used on a small marine vessel. (But then I could be completely wrong.

    Here's the cylinder assembly :-
    cylinder.jpg
    Note transfer pipes from distributor axle to cylinder heads.
    axle.jpg

    The distributor axle was a SOB to make - but no scrap thus far. For scale that's an M6 thread.
    The anulus grooves provide the inlet/exhaust timing.

    This is mostly going to be hidden in a wooden barrel "insulator" with hoops.

    Regards, Ken
