to move slightly relative to such blow to prevent undue shearing and damage to the total barge bumper assembly 15 the shock cell assembly 75 operates in the same manner as the shock cell assembly 22 and thus has been given the same numerals to indicate the similarity of operation including the positioning of the cstable polyurethane 36 as further illustrated the end 77 of the piston 29 extending outwardly from the interior of the cylinder 23 is suitably secured such as by welding at 78 to a stinger or stabbing base member 80 the stabbing base member 80 extends upwardly and is tapered inwardly as at 81 and further tapered inwardly at section 82 to form a stinger or stabbing member 84 which extends upwardly to terminate at end 85 as further illustrated the member 44 is pivotally attached at 51 through a suitable pivot pin not shown to the end 42 of piston member 29 in the upper shock assembly 22 and extends downwardly such that member 44 which is a cylindrical hollow member is positioned concentrically relative to stabbing member 85 to terminate at 90 on base member 80 by wedging base member 80 due to the taper of such base member 80 such that base member 80 has a larger cylindrical diameter than member 44 as further illustrated in the figure base member 80 also extends upwardly and includes a straight cylindrical wall portion 91 which extends upwardly and is attached to rigid support plate 92 which receives and supports a loose barge bumper support.
