Abstract
Abstract A sealing device for the lubrated bearings in the yokes of a universal joint for the journals of the arms of the cross piece. The sealing device comprises a double-lipped rubber gasket and an annular L-shaped clip for retaining the gasket on the bearing. The gasket straddles the inwardly directed horizontal leg of the clip squeezing one of the lips against the end of the bearing. The other leg of the clip has a projecting detent cooperating with a groove in the periphery of the bearing for securing the clip to the bearing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
183 words
A sealing device for use in universal joints of the type including a pair of yokes, a cross piece joining the yokes, the arms of the cross piece being mounted for rotation in bearings arranged in the yokes, comprising a lipped rubber gasket for sealing each bearing, an annular clip for retaining each gasket in position on its associated bearing, each said clip being secured to its associated bearing coaxial to the associated arm and having an inner circular flange engaging the lipped gasket, said annular clip being generally L-shaped in cross-section, and wherein the rubber gasket straddles the inner flange formed as the horizontal leg of the L-shaped section, the other vertical leg of the L-shaped section carrying securing means for cooperating with complementary securing means on the bearing to position each clip and rubber gasket axially relative to the associated bearing, the portion of the said clip joining the legs of the L-shaped section being slightly bulged out for facilitating the positioning of the lip of the gasket to be gripped between said clip and said one end of the bearing.
Claim 2
Dependent Claim
183 words

Claim 3
Dependent Claim
43 words
A device according to claim 1, wherein the securing means on the vertical leg of the L-shaped section comprises at least one projecting detent, and wherein the complementary securing means comprises an annular groove arranged in the outer peripheral surface of the bearing.
Claim 4
Dependent Claim
25 words
A device according to claim 2 wherein said clip is formed of plastic material thereby facilitating the engagement of each clip over its associated bearing.
Claim 5
Dependent Claim
35 words
A device according to claim 2 wherein said detent has a sloping surface remote from its associated rubber gasket forming a wedging surface for facilitating snap positioning of the associated clip on its respective bearing.
