DEFINITION

Classification: 248/527

(under subclass 524) Support wherein one or more of the retaining or centering means comprises a plurality of generally horizontal elements which are in threaded engagement with the device and are axially movable into or out of engagement with the staff. Where there are not more than two retaining or centering means, the screw usually constitutes the upper one of the means.

(1) Note. While a support of the kind found in this subclass usually has the capability of changing the attitude of the staff (e.g., to "plumb" it), it is not an angularly adjustable support within the meaning of subclass 514 above; see the reference therein to this subclass for an explanation of the difference.
