Perhaps connected with George Kingdon?
1886 Simpson and Denison exhibited at Liverpool a rotary engine based on Kingdon's patent, which was unusual in that the motive power is obtained by means of a reciprocating movement; every part of the engine with the exception of the bed plate and bearings rotated, thereby justifying the name of rotary.[1]
