US Patent RE46844 Connector assembly for connecting building members

A building assembly utilized in connecting building members together while permitting limited relative movement between the members. The assembly includes a structure such as a track or plate that includes one or more longitudinal slots. Integrally formed in the longitudinal slot is a breakaway washer that receives a fastener that extends into an adjacent structure. When a certain force is applied to the breakaway washer, the breakaway washer breaks away from the slot and this permits the slot to move about the breakaway washer and fastener which results in there being relative movement between two connected structures.
