I claim: 1. An adapter for securing a hoist or pulley mechanism to a threaded rod, comprising: a rigid support member; a first engagement means and a second engagement means aligned such that said threaded rod is axially engaged between said first and second engagement means, and said first and second engagement means are located proximal to a first end of said support member; and an opening disposed upon said support member and located proximal to a second end of said support member, wherein said first engagement means is disposed along a top edge of said support member and said second engagement means is disposed below said first engagement means and in offset arrangement such that a downward force acting on said opening of said support member further urges said first and second engagement means into frictional contact with said threaded rod. 2. The adapter of claim 1, wherein said rigid support member and said first and second engagement means are a single, unitary structure. 3. The adapter of claim 1, wherein said rigid support member, said first and second engagement means, and said opening are a single, unitary structure. 4. The adapter of claim 1, wherein said support member further includes a third and a forth engagement means disposed on an opposite side of said support member and substantially symmetric with said first and second engagement means. 5. An adapter for securing a hoist or pulley mechanism to a threaded rod, comprising: a rigid support member; a first engagement means and a second engagement means aligned such that said threaded rod is axially engaged between said first and second engagement means, and said first and second engagement means are located proximal to a first end of said support member; and an opening disposed upon said support member and located proximal to a second end of said support member, wherein said first and second engagement means comprise hemi-cylindrical channels positioned to engage said threaded rod in opposite sides thereof. 6. A method for converting an elevated threaded rod into a hoist, comparing the steps of: (a) providing a rigid support member having a first engagement means and a second engagement means aligned such that said threaded rod is axially engaged between said first and second engagement means, said first and second engagement means are located proximal to a first end of said support member, and an opening disposed upon said support member and located proximal to a second end of said support member; and (b) securing the rigid support member to said threaded rod, wherein the rigid support member is secured to the threaded rod by clamping said first and second engagement means to said threaded rod through application of downward force upon said support member. 7. The method of claim 6, further comprising the step of attaching a line or pulley to the opening of said rigid support member.
