Abstract
A reciprocating piston machine in the form of a barrel engine has angularly-spaced pistons directly centrally linked by wrist pins to radially extending branches of a spider obliquely journalled for nonrotational nutation on a Z-crank portion of a rotational shaft. The pistons are double-acting pistons providing two piston surfaces per cylinder in rodless connections to a single spider.
