Abstract: An internal combustion engine in which the longitudinal center line of the cylinders are parallel to and equally spaced around the longitudinal center line of the engine.The pistons, working within said cylinders, are mounted on a swash plate mechanism, by means of which the reciprocating motion of the pistons is translated into the rotary motion of a carrier plate to which the said swash plate is mounted and, from which, is taken the drive into the vehicle transmission.Said swash plate is mounted on a post at the circumference of the carrier plate and pivots around said post when moved, on a longitudinal axis, by a mechanism.As each piston, in turn, passes the point on the swashplate adjacent to the mounting post, it is at the top-dead-center position in its cylinder. As said piston passes the diametrically opposite point on the swash plate it is at the bottom-dead-center position.

Abstract: A wrench with relatively movable members to transmit gripping force between said members comprising a swinging element with the rear face of arcuate form on which side are gear teeth, a series of connecting links the final link forming the handle, said handle having an arcuate form on the outer face of similar profile to the first swinging element on which handle arcuate face are formed gear teeth in such a manner that, when the links enclose a pipe or similar round object and force is applied to said handle, the meshing gear teeth on the opposing arcuate faces drive the swinging element into frictional engagement with the pipe, urging said pipe into frictional engagement with the inside faces of the other links, said links having teeth formed on the inside faces in such a manner as to grip said pipe and angled in such a manner that, when further force is applied to said handle, the entire assembly is rotated about the longitudinal center line of the said pipe.
