Abstract
Abstract A lead-acid aircraft battery having a unique arrangement for making connections to the battery. The arrangement includes L-shaped members on the upper surface of the casing having cylindrical apertures extending horizontally therethrough. Threaded pin terminals insert through a receptacle assembly positioned to a side wall of the battery housing and are fastened by nuts to the L-shaped members. The pin terminals have axially-aligned surfaces for engaging a tightening tool so that assembly time is substantially reduced.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
An aircraft battery comprising a housing having an aperture in a wall thereof, a casing having a pair of electrical conductors leading therefrom, a cover for the casing through which the pair of conductors protrude, a pair of electrically conductive members each connected to one of the conductors and having an aperture therein aligned with the aperture in the wall of the housing, a receptacle positioned within the aperture in the wall of the housing and having apertures therethrough aligned with the apertures in the pair of members, a pair of electrically conductive pins each threaded at one end and having a surface thereon adapted to receive a wrench for rotating it about its axis, each pin being positioned with its threaded end passing through the apertures in the receptacle and the member and its other end extending beyond the housing, and means for securing the threaded ends of the pins to the members.
Claim 2
Dependent Claim
154 words
An aircraft battery comprising a housing having an aperture in a wall thereof, a casing having a pair of electrical conductors leading therefrom, a cover for the casing through which the pair of conductors protrude, a pair of electrically conductive members each connected to one of the conductors and having an aperture therein aligned with the aperture in the wall of the housing, a receptacle positioned within the aperture in the wall of the housing and having apertures therethrough aligned with the apertures in the pair of members, a pair of electrically conductive pins each threaded at one end and having a surface thereon adapted to receive a wrench for rotating it about its axis, each pin being positioned with its threaded end passing through the apertures in the receptacle and the member and its other end extending beyond the housing, and means for securing the threaded ends of the pins to the members.
Claim 3
Dependent Claim
44 words
An aircraft battery as claimed in claim 1 wherein the surface on each of the pair of pins is a regular hexagonal surface positioned between the threaded end and the other end thereof and adapted to exert pressure upon the receptacle when in place.
Claim 4
Dependent Claim
35 words
An aircraft battery as claimed in claim 1 in which the means for securing the threaded ends of the pins to the members comprises nuts adapted to fasten to the threaded ends of the pins.
