Abstract
Abstract A wedge assembly for spacing apart batteries which permits a complete rangef operation with all components remaining intact in their assembled form is provided. A central or inner wedge having a plurality of identical wedge sections is movable between a pair of outer wedges or side plates having mating inner sections and a planar outer surface. Wedging action is produced by torquing a bolt secured to the outer wedges and threaded through a nut secured in the inner wedge. The wedging components are held together and in alignment by screws attached to the inner wedge and guided through slots formed in the outer wedges.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
256 words
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.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
38 words
The device as defined in claim 1 wherein in the initial condition the ends of said outer members remote from said bolt head abut and are contoured to facilitate insertion of said device between two closely spaced objects.
Claim 4
Dependent Claim
56 words
The device as defined in claim 2 wherein the angled surfaces of said wedge sections taper toward said bolt head at an angle of substantially 8°-20' with respect to a plane longitudinally bisecting said wedge sections to permit operation of said device against friction between selectively wide adjacent tapered surfaces of said central and outer members.
