Abstract
A U-shaped latch having a pair of resilient arms is fixed radially and axially in an annular groove formed in the neck of the spindle house. The latch is provided with a projection which passes through a hole in the neck into engagement above a collar integral with the spindle blade, thereby preventing axial movement of the spindle blade. The projection is formed so as to be centered on the inside rim of the latch so that upon radial shifting of the latch, the projection is moved from its engaging position to a disengaging position. The forked latch provides the necessary spring tension to hold the latch in place in either position.
