Centering sleeve and overflow ring assembly

Abstract

A centering sleeve and overflow ring assembly adapted to facilitate proper installation in a hole drilled in masonry of a stud for fastening a fixture or other object to the masonry. Deposited in the hole is a charge of a flowable bonding agent which when cured then anchors in place the stud inserted in the hole. The ring is preferably formed of a flat, tearable material and is seated on the masonry in registration with the hole. The sleeve which is snugly nested in the upper end of the hole includes inwardly-directed centering means that engage the stud inserted in the hole to maintain the stud centered therein while providing a flow passage between the stud and the sleeve. When the inserted stud plunges into the charge of bonding agent, the agent then rises in the hole and passes through the flow passage in the sleeve to overflow onto the ring. After the overflow accumulated on the ring cures and hardens, it can then be discarded by tearing off the ring. The centering means may be arranged to retard gravity flow of the agent from the sleeve should the sleeve be nested in a hole drilled in overhead or vertical masonry, thereby preventing leakage of the agent from the hole.
