DRIVE ROD COUPLING FOR POSITIVE DISPLACEMENT PUMP Abstract of the Disclosure A coupling device for use in a gas operated posit- ive displacement reciprocating pump, which disconnectably accomodates two rigid, elongated reciprocating elements while maintaining contact between the elements and eliminating relative longitudinal movement. Included is a hemispherically faced connector head connected to one of the elements. The coupling device further includes a retainer connected to the other of said elements into which the head is positioned. The connector head is contained in the retainer by a retaining member and biased against a bearing within the retainer by a plurality of Belleville washers. The force developed by the washers is sufficient to maintain the hemispherically faced connector head in contact with the connector bearing to insure that the connector head and bearing do not separate relative to each other during reciprocation of the rigid elements.
