Battery wedge for submarines or other installations

In a wedge device for spacing apart or elevating or lowering objects wherein a central member is movable with respect to adjoining outer members and all components are required to be contained entirely within the envelope formed by the outer surfaces of said outer members the improvement comprising:

• a linear succession of dual-faced oppositely-angled wedge sections in said central member,
• the inner surfaces of said outer members mating with the adjoining surfaces of said central member when in the initial condition;
• a bolt interconnecting said central and outer members and disposed in selectively extensive recesses therein,
• a nut anchored in a recess in said central member and said bolt threaded through said nut and having its head received in recesses in said outer members,
• a thrust plate anchored in said outer members and positioned in recesses therein immediately forward of the interior face of said bolt head,
• said bolt extending from a position within the end of said device toward which said wedge sections taper substantially thereinto so as to power said central member from at least the next to the end wedge section thereof;
• and
• spaced guide and restraining means secured two each symmetrically to said section containing said nut and a section remotely spaced therefrom and a like number of slots conforming to said guide and restraining members formed in said outer members,
• whereby all operative components are contained within the outer configuration of said device permitting unrestricted placement thereof and both expansion and contraction of said outer members by operation of said bolt.
