Abstract
Plate blocks are clamped by pneumatically inflatable multilayer elements.
Claims11
Apparatus for clamping together the plate blocks of lead storage batteries, comprising:
- at least one clamping element positioned adjacent an outer surface of the block,
- the element having generally planar face engaging the block surface,
- the element being constructed so that the planar face is pneumatically deformable so as to bulge toward the adjacent block surface, thereby to apply a controllable clamping force to said surface,
- the element having a multi-layer construction, including innermost layers formed of an elastic membrane, and resilient plates adjacent portions of the outer surfaces of the membrane, and means for introducing gas under pressure between the innermost layers,
- the elastic membrane being responsive to the gas pressure to expand, thereby pressing outwardly against the resilient plates and causing them to bulge and provide the clamping force, and
- the element having bulkheads positioned between the membrane and the plates, the bulkheads having cut-outs through which the membrane can bear against the plates.
A pneumatic clamping element having generally planar face deformable so as to bulge and having a multilayer construction, the element including:
- innermost layers formed of an elastic membrane,
- resilient plates adjacent portions of the outer surfaces of the membrane,
- means for introducing gas under pressure between the innermost layers, the membrane being responsive to the gas pressure to expand, thereby pressing outwardly against the adjacent resilient plate portions and causing the plates to bulge, and
- bulkheads positioned between the membrane and the plates, the bulkheads having cut-outs through which the membrane can bear against the plates.
