TEE type of universal joint known as the Mechanics, which is manufactured by the Mechanics Machine Co., of Rockford, Ill., is of aa advanced and efficient design. The narrow surfaces employed on the casings and the great pressure exerted by the nuts when these are drawn into place make for a high unit pressure between the surfaces in contact and enable a tight joint to be
obtained: , .
There is a slight discharge of oil when the joints are first operated at high speeds under heavy load's, owing to the rise of temperature which .4:wears, causing a slight expansion which has a tendency to force out a small amount of the lubricating oil.
The packing washers are completely surrounded by the metal parts of the joint, making the bearing surfaces proof against any foreign matter that might enter from outside they also serve efficiently to retain the lubricant.
The spline fitting operates independently of the joint proper, centri B28 fugal force driving the lubricant away from the splines, leaving them comparatively dry.
The housing of each joint is made in two parts. The first part contains the two yokes with the driving trunnions and the second the four bashes. Both parts are made of steel stampings-.
It is claimed that,, owing to the efficient lubrication obtained, it should seldom be necessary to dismantle a
joint. Should it be desirable to dissemble the joint in a vehicle where no companion flange is used, it can be done by removing the eight nuts holding together the halves of the housing.
It is stated by the British concessionaire, Benjamin Whittaker, Ltd., Aldwych House, Aldwych, London, W.C.2, that these joints are being increasingly employed by British and Continental chassis manufacturers as well as by many American makers.
