The interstices 33, 34 between the spokes extend both radially and circumferentially and the walls 35 of the interstices 33 diverge upwardly. A collar 38 is fixed on the shaft and when the latter rotates the collar presses upwardly so as to cause the disc 17 to assume the position shown in dotted lines in Fig. 1.

A packing ring 36 and rubber grommet 37 are provided between the shaft 13 and its bearing housing 16. Specification 846,111 is referred to. |
