ABSTRACT:
A self aligning joint and linkages employing the self aligning joint. The joint includes a stem; a clevis mounted for rotation on one end of the stem and defining a pair of spaced arms; a stud having a circumferential groove proximate one end thereof; a body member positioned between the clevis arms and defining a socket mounting the one end of the stud for rotation about the axis of the stud; and an axle pin mounted at opposite ends in the clevis arm, passing through the body member to mount the body member for angulation about the pin axis, and including an intermediate portion positioned in the stud groove to preclude axial displacement of the stud out of the socket. Also disclosed are linkages including an elongated tubular member, an elongated rod member mounted for rotation in the tubular member and including a free end projecting out of one end of the tubular member, a self aligning joint according to the invention secured to the free end of the rod member, and a further self aligning joint secured to the end of the tubular member remote from the rod member. The self aligning joints in this case are " zero angle" joints providing only two degrees of movement with the third movement being provided in each case by relative rotation between the tubular member and the rod member.
