To all whom it may concern:

riveted at its lower end to the top of this cup,
vso kthat the cup will turn ivi'th the spindle, the cup 'resting asainsta shoulder 10 on the spindle Which rests upon the top 'of the shoulder 10, land this disk has recesses 12 therein formed .by tongues 13 struck up on opposite sides of the spindle. A spriii;r 1d is mounted upon the spindle, with the reduced ends 15 of its branches fitting` in the slots 12, and this spring is held on the spindle by a Cotter 16 l at the top.

The shell is held in place on the cup by means of 'clips 19 produced at the upper edge thereof which when the parts are assembled are struck in over the shoulder 8. To remove the shell and the balls it is necessary simplyto pry out the tongues 19 with a screw driver or similar implement and pull oit' the shell 6.

All the parts can be readily produced', the spindle being cast or turned and the-shell, cup, spring, bracket, and disk, being stamped out of sheet metal.
