Abstract:
1. An adjustable spacer assembly comprising: first and second opposed wedges each having opposed inclined surfaces and a bore extending in a transverse direction; a semi-longitudinal threaded rod connector having oppositely pitched threads at each end and adjustable in position to determine relative positions of said first and second wedges, said wedges being constrained by said semi-longitudinal threaded rod connector being received within the bore, so that a vertical distance between an upper face and a lower face of said first and second wedges respectively changes as said first wedge is translated in a longitudinal direction with respect to said second wedge in response to a change in position of said semi-longitudinal threaded rod connector; and first and second cylindrical members located at said first and second wedges each to retain said first wedge and said second wedge respectively to said semi-longitudinal threaded rod connector and each permitting pivotal movement of said semi-longitudinal threaded rod connector with respect to one said wedge, wherein one said cylinder member comprises a threaded collar for rotation of said semi-longitudinal threaded rod connector in said threaded collar.
