For use in determination of chain transmitted power, the combination comprising a tensioned chain having a succession of chain links with undulating edges; an idler supported to be driven in rotation by the chain, and having an undulating perimeter surface having a sine wave configuration and whose width dimension exceeds the width dimension between outermost chain surfaces; and certain of the chain undulating edges engaging portions of the idler undulating perimeter surfaces, whereby the chain changes direction as it travels lengthwise relative to the idler and rotatably drives the idler.

[ We claim:] [1.] For use in determination of chain transmitted power, the combination comprisinga) a tensioned chain having a succession of chain links with undulating edges, certain of said links being side links,b) an idler supported to be driven in rotation by the chain, and having an undulating perimeter surface, said idler having an axis,c) certain of said chain undulating edges engaging portions of said idler undulating perimeter surface, whereby the chain changes direction as it travels lengthwise relative to the idler and rotatably drives the idler,d) said idler undulating perimeter surface having outwardly convex substantially sine wave configuration surface portions in radial alignment with and radial engagement with said chain side links, the width of said idler undulating perimeter surface exceeding the width dimension between outer surfaces of the side links.
