bearing is a plate adapted to the inner wall of the piston and restingagainst a flange or shoulder m therein. This plate has a semispherically or convexly curved projeotionf, corresponding to the concaved or cup-hke end of the connecting-rod, which projection 6o constitutes a bearing therefor.
gis a retaining-gland arranged to bear underneath thocupped end of therod'c, so as to hold the rodin its proper position relatively to the bearing cndf. This retaining-gland is preferably splitinto two sections g Fig. 2, to facilitate its ready application. Any suitable means may be provided to hold this gland in its proper position. One means to accomplish this end may comprise a split and arranged to take into corresponding screw threads inside of the trunk-piston and below the gland g when the latter is inpla ce. By setting upon this split ring the desired ad= justrnent may be obtained, and when attainedthe ring'may be eX iairded-fM example,'by means of an expaiuling-screw -iso as to lock it s'ecurely in place. T he ring it may lee-provided with projections to facili 8o tate turning it. I i In assembling. the parts the bearing-plate e is placed in position, the connecting-rod is entered, with its cupped end placed inconring 71, screw-threaded. externally tact with the bearing f, the-retaininggland g 5 or lower-bearing is then inserted, and finally the split ring is moved up on the threaded interior of the'trunk-piston until the desired adjustment is attained, whereupon-the split ring may be locked'in place. When assem-- o Bled, it will beobserved that the rod may partake of a universal movement, which is of decided'advantage, for is obvious that by such a movement in use the piston mayturn in the cylinder Without disturbing the con- 5 necting-rod, so as to compensate for all wear. Furthermore, since the connection is not held in onedeiinite position it will not wear out. of round, as does a piston with the usual These and other advantageswill be apparent to'mechanics skilled in'the art; but not the least is the matter of"'e cononiical,constructio'n and the advantage that this connection possesses in that it permits the m5 trunk-piston to have a QOIltEtYPd or semisplterically-cupped'end 5) without unduly increasing-the length of said piston".
