Abstract
A control device, such as a U-shaped member including opposingly directed tab projections connected to the upstanding arms of the member may be coupled to a space block of a dynamoelectric machine for limiting motion, especially inward radial motion, of the block. In one embodiment, the space block has a groove for forming a portion of a keyway between the space block and a flange and the tabs of the member are disposed in the keyway radially outward a key which is dimensionally smaller than the groove, so that the tabs abut a sidewall of the groove, thereby limiting motion of the block when the key contacts the tabs.
