Abstract: The assembly comprises a shaft or any other torque transmitting means, and a coupling element which is of sheet metal and has a hub including a portion provided with an axially extending slot whose width is sufficient to allow an assembly by a relative radial displacement of the shaft and hub. The sides of the hub portion defining the slot are extended at least locally and substantially perpendicularly to the axial plane of symmetry by ears which extend outwardly. The ears cooperate with an attached member which is disposed transversely of the slot so as to interconnect the hub and shaft owing to the action of clamping means. Each of the ears is folded horizontally onto itself so as to form a double thickness of the ear.

Abstract: An outer collar on a power takeoff yoke sleeve locks against an inner collar to rotate the yoke and sleeve in a first direction to align splines within the sleeve with splines on a power takeoff stub shaft. Cooperating teeth between the inner collar and the outer collar permit the outer collar to rotate freely in the opposite direction. The outer collar surrounds the inner collar and detent operators and the small end of a ball which protects the yoke from unintentional contact. The outer collar is grasped and is slightly turned to align the yoke splines and stub shaft splines while pushing the outer collar toward the stub shaft to slide the sleeve over the stub shaft. The stub shaft pushes a detent holdout longitudinally and releases the detent to move inward into a groove on the stub shaft. A heavy spring on the sleeve pushes a detent operating and locking device axially to move the detent inward into the groove in the stub shaft.

Abstract: A universal joint is composed of first and second yokes each having two through holes, a hollow rectangular parallelepiped support member positioned to cooperate with the first and second yokes, the support member having five rectangular plate sections leaving a rectangular opening, and formed with four through holes, the adjacent rectangular plate sections being completely integral with each other at connecting edges thereof, and pins insertable into the through holes of the yokes and of the support member so as to connect the yokes with the support member, thereby producing a universal joint light in weight and high in torsional strength.

Abstract: Disclosed herein is a universal joint yoke 1 having a rotational axis Y--Y and an opposed pair of arms 3 with bores 9 having a common axis X--X; the sectional shape of the arms in that plane perpendicular to the rotational axis Y--Y and passing through the common bore axis X--X having end portions 10 inturned towards the rotational axis Y--Y so that a greater depth h of bore may be obtained than the bore depth h' of a yoke of equivalent radial size formed from the same thickness material e and having arms 16 wherein the corresponding section is part circular.

Abstract: A universal joint assembly which includes a first and a second yoke operatively interconnected by a trunnion cross arranged therebetween is formed with a generally centrally located bore extending through the trunnion cross between the first and the second yoke with a bolt extending within the bore interconnecting the first and second yoke through the trunnion cross. One end of the bolt is attached to a radially movable member in the first yoke and lock means are provided for locking the radially movable element in any selected position in order to fix the position of a connecting member joined to the second yoke so that interconnection of torque transmitting elements may be facilitated.
