Abstract
Abstract In a system for adjusting the position of a structure relative to its foundation and thereafter rigidly securing the structure in the exact position of adjustment, there is herein disclosed a locking device including a meltable matrix material disposed in an opened-top cavity in a base and also including a support member extending into the matrix material which material rigidly holds the support member in a fixed position until a heating element in the support member is activated. Once freed, the structure may be moved by any conventional auxiliary mechanism, and when so aligned the support member is again locked by deactivating the heating element.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
A locking device for an adjustable support system, comprising: a base member having at least two cavities therein and an upper surface, said cavities communicating with said upper surface; a meltable matrix material disposed in said cavities, said matrix material being in its solid state at ambient temperature; and a separate structure support member associated with each of said cavities, said support members having lower portions extending down into said cavities in spaced relation to the walls thereof and immersed and rigidly held in a fixed position by said matrix material, said support members each including heating means for melting said matrix material and thereby freeing said support members to move in six degrees-of-freedom only for the time said matrix material is in its molten state.
Claim 2
Dependent Claim
126 words
A locking device for an adjustable support system, comprising: a base member having at least two cavities therein and an upper surface, said cavities communicating with said upper surface; a meltable matrix material disposed in said cavities, said matrix material being in its solid state at ambient temperature; and a separate structure support member associated with each of said cavities, said support members having lower portions extending down into said cavities in spaced relation to the walls thereof and immersed and rigidly held in a fixed position by said matrix material, said support members each including heating means for melting said matrix material and thereby freeing said support members to move in six degrees-of-freedom only for the time said matrix material is in its molten state.
Claim 3
Dependent Claim
23 words
A device according to claim 1, wherein said structure support members extend from an adjustable support plate in a spaced but parallel relationship.
