An expansion ring assembly for sealing a gasket within an opening in the wall of a structure, the assembly including a drive mechanism having a pair of block members each having a threaded bore, and a bolt having oppositely threaded ends respectively threaded within the bores. The block members are removably engaged with respective ends of the expansion ring. An oversleeve is disposed in overlapping relationship with the expansion ring ends, and the expansion ring ends and the oversleeve include cooperating ratcheting structures. Rotation of the bolt of the drive mechanism in a first direction causes the block members to move outwardly along the bolt to expand the expansion ring and concurrently sequentially engage the ratcheting structures of the expansion ring ends and the oversleeve.

What is claimed is: 1. An expansion ring assembly, comprising: a ring including a pair of overlapping end portions, said end portions including ratcheting structures in engagement with one another; and a drive mechanism, comprising: a pair of block members each having a threaded bore therein, said
What is claimed is: 1. An expansion ring assembly, comprising: a ring including a pair of overlapping end portions, said end portions including ratcheting structures in engagement with one another; and a drive mechanism, comprising: a pair of block members each having a threaded bore therein, said bores of said block members being oppositely threaded, said block members removably engaged with respective end portions of said ring; and a bolt including oppositely-threaded ends respectively threaded within said bores of said block members, whereby rotation of said bolt in a first direction causes said block members to be simultaneously driven apart from one another to thereby expand said ring and sequentially engage said ratcheting structures of said ring end portions with one another. 2. The expansion ring assembly of claim 1, wherein said ratcheting structure of one of said ring end portions comprises a ratchet connector including a series of ratchet teeth, one of said block members removably engaged with said ratchet connector. 3. The expansion ring assembly of claim 2, wherein said ratchet connector is formed separately from said ring end portion. 4. The expansion ring assembly of claim 1, wherein said ratcheting structure of one of said ring end portions comprises a ratchet segment portion including a series of ratchet teeth. 5. The expansion ring assembly of claim 4, wherein said ratchet segment portion is formed separately from said ring end portion. 6. The expansion ring assembly of claim 4, wherein said one ring end portion further comprises a stop member, one of said block members removably engaged with said stop member. 7. The expansion ring assembly of claim 1, wherein said drive mechanism is disposed substantially within said ring. 8. The expansion ring assembly of claim 1, wherein each of said block members is made of a plastic material, and includes a threaded metal insert member molded therein. 9. The expansion ring assembly of claim 1, wherein said ring includes a longitudinal axis, said bolt disposed perpendicular to said longitudinal axis. 10. An expansion ring assembly, comprising: a ring including a pair of end portions, at least one of said end portions including first ratcheting structure; an oversleeve disposed in overlapping relationship with said ring end portions, said oversleeve including a pair of opposite ends, at least one of said opposite ends having second ratcheting structure in respective engagement with said first ratcheting structure of said ring end portions; and a drive mechanism, comprising: a pair of block members each having a threaded bore therein, said bores of said block members being oppositely threaded, said block members removably engaged with respective end portions of said ring; and a bolt including oppositely-threaded ends respectively threaded within said bores of said block members, whereby rotation of said bolt in a first direction causes said block members to be simultaneously driven apart from one another to thereby expand said ring and sequentially engage said first ratcheting structure of said ring end portion with said second ratcheting structure of said oversleeve. 11. The expansion ring assembly of claim 10, wherein each of said end portions of said ring include said first ratcheting structure and each of said ends of said oversleeve include said second ratcheting structure, with respective pairs of said first and second ratcheting structures in engagement with one another. 12. The expansion ring assembly of claim 10, wherein said at least one first ratcheting structures comprises a ratchet connector including a series of ratchet teeth, one of said block members removably engaged with said ratchet connector. 13. The expansion ring assembly of claim 12, wherein said ratchet connector is formed separately from said at least one ring end portion. 14. The expansion ring assembly of claim 10, wherein said at least one second ratcheting structure comprises a ratchet segment portion of said oversleeve, said ratchet segment portion including a series of ratchet teeth. 15. The expansion ring assembly of claim 10, wherein said drive mechanism is disposed substantially within said ring, and said block members are removably connected to respective end portions of said ring. 16. The expansion ring assembly of claim 10, wherein each of said block members is made of a plastic material including a threaded metal insert member molded therein. 17. The expansion ring assembly of claim 10, wherein said ring includes a longitudinal axis, said bolt disposed perpendicular to said longitudinal axis. 18. The expansion ring assembly of claim 10, wherein said end portions of said ring define an opening in said ring therebetween, said opening spanned by said drive mechanism.
