Abstract: A mechanism for reciprocating engines or pumps, the mechanism transmitting power from the axially arranged piston rods to the axially arranged main shaft via a slant fixed to said shaft and a cross head gripping and sliding on the edge of the slant. The inward directed components of the rotating transverse force vector T are absorbed by one or more Michell thrust blocks sliding on a cylindrical surface coaxial with the main shaft.

Abstract: A power transmitting mechanism for reciprocating engines or pumps connecting the piston rods of a plurality of cylinders with a slant on a main shaft, the cylinder axes being parallel with the main shaft. The connection is provided by means of claw-shaped crossheads gripping the slant, one crosshead for each piston rod. Between the crosshead and the slant a main thrust block and a back thrust block are placed eccentrically. The crosshead may pivot around its longitudinal axis and is provided with two thrust blocks of the Michell type, the centres of these two blocks being arranged in a plane perpendicular to the longitudinal axis of the crosshead and in the middle of the gap of the crosshead.
