Reconfigurable heavy duty battery holder

Claim 2

A battery holder comprising: a cylindrical body having an axis of revolution, and first and second ends each of said ends having a flat face disposed orthagonally thereon with respect to said axis of revolution and a plurality of cylindrical battery chambers spaced radially about said faces of the body and extending longitudinally through the body from said first end to said second end, each battery chamber being of a diameter and length to accommodate a plurality of battery cells connected in series; two end caps, each having a plurality of contact apertures therein and therethrough arranged radially with each contact aperture portioned in correspondence with one battery chamber; fastening means removably attaching said end caps to said first and second ends of said body thereby covering said battery chambers; contact springs disposed on each end cap on the body side thereof with each contact spring disposed at each of said contact apertures; electrically conductive bolts passing through each of said contact apertures in said end caps and electrically connecting each contact spring; and electrically conductive plates removably engaged by said electrically conductive bolts on the exterior side of said end caps, said plates being positonable to select different voltages from the battery holder.

Claim 3

The battery holder according to claim 1 wherein the fastening means comprises fasteners passing through the end caps at fastening apertures disposed in the faces thereof and extending therethrough, said fasteners engaging the body at body fastening apertures in the faces thereof.

Claim 4

The battery holder of claim 2 further comprising at least two detachable electrically conductive leads capable of being removably fastened and electrically connected to any of said electrically conductive bolts.

Claim 5

The battery holder according to claim 3 wherein said body has two longitudinal mounting grooves opposite each other on either side of said body, and said end caps have two longitudinal mounting grooves opposite each other on either side of said end caps.

Claim 6

The battery holder according to claim 4 wherein said contact spring is an electrically conductive helical spring.

Claim 7

A battery holder comprising: a cylindrical body having an axis of revolution, and first and second ends, each of said ends having a flat face disposed orthagonally thereon with respect to said axis of revolution with a plurality of cylindrical battery chambers spaced radially about said faces of the body and extending longitudinally through the body from said first end to said second end such that said body surrounding said chambers is substantially rigid and able to withstand heavy usage, each battery chamber being of a diameter and length to accommodate a plurality of standard battery cells connected in series, said body having two longitudinal mounting grooves opposite each other on the exterior surface of said body, and said body having fastening apertures in the faces thereof; two removable disk shaped end caps with a plurality of contact apertures therein therethrough arranged radially with each contact aperture positioned in correspondence with one battery chamber, said end caps having mounting slots opposite each other corresponding to said mounting grooves on said body, and said end caps having fastening openings in the face thereof and extending therethrough; at least two fasteners securing said end caps to said body by passing through said fastening opening in each end cap and engaging said body at the fastening aperture therein; contact springs disposed on each end cap on the body side thereof with each contact spring disposed at each of said contact apertures; electrically conductive bolts passing through each of said contact apertures in said end caps and electrically connecting each contact spring; and electrically conductive plates removably engaged by said electrically conductive bolts on the exterior side of said end caps, said plates being positonable to select different voltages from the battery holder.

Claim 8

A battery holder comprising: a cylindrical body having an axis of revolution, and first and second ends, each of said ends having a flat face disposed orthagonally thereon with respect to said axis of revolution with a plurality of cylindrical battery chambers spaced radially about said faces of the body and extending longitudinally through the body from said first end to said second end such that said body surrounding said chambers is substantially rigid and able to withstand heavy usage, each battery chamber being of a diameter and length to accommodate a plurality of standard battery cells connected in series, said body having two longitudinal mounting grooves opposite each other on the exterior surface of said body, and said body having fastening apertures in the faces thereof; two removable disk shaped end caps with a plurality of contact apertures therein therethrough arranged radially with each contact aperture positioned in correspondence with one battery chamber, said end caps having mounting slots opposite each other corresponding to said mounting grooves on said body, and said end caps having fastening openings in the face thereof and extending therethrough; at least two fasteners securing said end caps to said body by passing through said fastening opening in each end cap and engaging said body at the fastening aperture therein; contact springs disposed on each end cap on the body side thereof with each contact spring disposed at each of said contact apertures; electrically conductive bolts passing through each of said contact apertures in said end caps and electrically connecting each contact spring; and electrically conductive plates removably engaged by said electrically conductive bolts on the exterior side of said end caps, said plates being positonable to select different voltages from the battery holder.

Claim 9

The battery holder of claim 6 further comprising at least two detachable electrically conductive leads capable of being removably fastened and electrically connected to any of said electrically conductive bolts.

Claim 10

The battery holder according to claim 7 wherein said contact spring is a helical spring.
