Abstract
A cradle device of integral construction provides stable support for an underground curb cock positioned at the bottom of a vertical curb box conduit. The device embraces the curb cock, thereby preventing its movement and maintaining its valve stem in an upright position so that it can be engaged by a long stemmed key. The device also provides secure footing for the curb box conduit.

A cradle device for a curb cock comprised of a housing having an outwardly protruding uppermost circular shoulder and a valve stem provided with an uppermost engagement head, said cradle device being of integral monolithic construction and comprising:
- (a) a base portion adapted to be horizontally disposed, having an upper surface, flat lower surface, and centered circular aperture,
- (b) an elongated upwardly opening trough defined by paired parallel walls rising upwardly from the upper surface of said base portion and positioned such that said circular aperture is centered on the midpoint of the longitudinal axis of said trough, the width of said trough, measured between facing surfaces of said walls, being such as to closely accommodate a curb cock and pipes associated therewith,
- (c) four narrow slots vertically disposed in said walls in paired relationship in a circular locus centered upon said circular aperture, said slots being adapted to seat the lowermost extremity of a curb box of circular contour, and
