Self-aligning joint for linkages

A joint comprising:

• a stem;
• a clevis on one end of said stem defining a pair of spaced arms;
• a stud;
• a body member positioned between said clevis arms and defining a socket mounting one end of said stud for rotation about the axis of the stud;
• and
• an axle pin having opposite ends in said arms, passing through said body member, and mounting said body member for angulation about the axis of the pin, the pin axis being perpendicular to the axes of said stud and said stem, intersecting the stem axis, and laterally displaced from the stud axis.

A joint comprising:

• a stem;
• a clevis on one end of said stem defining a pair of spaced arms;
• a stud;
• a body member positioned between said clevis arms and defining a socket mounting one end of said stud for rotation about the axis of the stud;
• and
• means mounting said body member for angulation about an axis perpendicular to the axes of said stud and said stem;
• said mounting means comprising an axle pin mounted at its opposite ends in said arms and passing through said body member to mount the body member for angulation about the axis of the pin;
• said stud including a circumferential groove proximate said one end of said stud and positioned in said socket;
• and
• said axle pin including an intermediate portion positioned in said stud groove.

A joint comprising:

• a stem;
• a clevis on one end of said stem defining a pair of spaced arms;
• a stud having a circumferential groove proximate one end thereof;
• a body member positioned between said clevis arms and defining a socket mounting said one end of said stud for rotation about the axis of the stud;
• and
• an axle pin having opposite ends mounted in said clevis arms, passing through said body member to mount said body member for angulation about the pin axis, and including an intermediate portion positioned in said stud groove.

A joint comprising:

• a support member;
• a stud having an end portion of circular cross section and defining a circular circumferential groove in the end portion;
• a body member defining a socket of circular cross section having a diameter corresponding generally to the diameter of the end portion of the stud, said end portion of the stud being rotatably mounted in the socket to mount said stud for rotation in said socket about the axis of the stud and further defining a single continuous bore extending through the body member normal to the stud axis, intersecting said socket, and opening in said socket in alignment with said groove;
• and
• a pin supported at its opposite ends by said support member, journalled in said bore to mount the body member for angulation about the pin axis, and including a portion positioned in said annular groove to preclude axial displacement of said stud out of said socket while allowing rotation of the stud in the socket of the body member.

A joint comprising:

• a stem including a stem member;
• a stud;
• a body member defining a socket mounting one end of said stud for rotation about the axis of the stud;
• and
• means, including a clevis defining a pair of spaced arms and an axle pin mounted at its opposite ends in said clevis arms mounting the body member on the stem for angulation about an axis normal to the axes of said stem structure and said stud;
• said clevis forming a part of said stem structure and said pin including an intermediate portion passing through said body member;
• said stud including a circumferential groove proximate said one stud end and positioned in said socket;
• said intermediate portion of said pin passing through said stud groove.
