First Claim
Patent Images
1. In combination;
- a dry cell battery of a first nominal cross section and an adapter to render the battery interchangeable with a battery of a second, larger nominal cross section, said adapter comprising a body having a central passage opening at opposite ends thereof and constituting means for receiving a battery of said first nominal size insertable therein and removable therefrom from both ends of the body, said passage having the battery received therein and said body having at least two internal flanges projecting into said passage, radially innermost surfaces of said flanges being cylindrical and constituting means engaging and supporting said battery, the external transverse dimensions of the body being substantially similar to those of a battery of said second and larger nominal size.

2. In combination;
- a dry cell battery having positive and negative electrodes at opposite ends and a nominal transverse circular cross section; and
an adapter to render the battery useful in an application for which it would otherwise be too small, said adapter comprising a generally tubular body of no greater length than the spacing between the electrodes of the battery, a central, longitudinal passage opening at opposite ends of said body, battery support means within said passage, said support means comprising inwardly directed flanges on said body projecting into said passage and having radially innermost cylindrical surfaces engaging said battery, said body having an external transverse cross section to fit the battery for said application for which it is otherwise too small, said battery being received within said passage and supported by said support means, the electrodes being disposed beyond the ends of the body and said passageway constituting means for receiving said battery said battery being insertable into and removable from each end of said body. - View Dependent Claims (4)
