发明名称 LID STABILIZING APPARATUS
摘要 The lid stabilizing apparatus is principally directed to a structure which will resist a force on a lid which will tend to dislodge the lid from the structure which it covers. Of particular interest is the lid covering municipal water valve structures where such lids are repeatedly struck by vehicular traffic and are dislodged and thrown into the street. The downwardly extending rod with stabilizing and, where desired, n-stabilizing disks, will be in friction or near friction contact with the pipe which is upwardly directed from a valve accessed from the street surface. This friction or near friction contact will resist the dislodging of the valve lid.
