Abstract

This application discloses an automatic battery charger for use with an electric automobile, golf cart, or any vehicle using a storage battery. The invention resides in the particular combination and arrangement of elements particularly a structure embodying a fixed male charging section, and a portable female section, which is carried on the vehicle. The sections being brought into mating and charging relation when the vehicle is moved into a certain position, and the sections being disconnected when the vehicle is moved away from that position.

Claims

1. The combination, with a highway-traveling motor vehicle having a storage battery, of a battery-charging system, comprising a fixed portion, including a battery charger in circuit with a pair of elevated male electrodes, each of which is normally covered with a spring-biased, slideable, insulating means, a portable portion including a pair of female elements for receiving said male electrodes, and in circuit with the said storage battery, the fixed portion being normally removed from said vehicle and said portable portion being carried by said vehicle, and electric elements, including a switch, arranged to be closed to conduct current through said battery charger to said battery when said male and female electrodes are properly mated, the said switch being arranged to be closed by the forward movement of said vehicle and said switch being arranged to be opened when said vehicle is moved in a reverse direction, the said fixed portion having vertically and horizontally adjustable members for supporting said male electrodes.

2. The structure of claim 1, in which said fixed portion includes a base member, which supports said charger, a pair of upright members secured to said base member and a nonconductive crossmember vertically adjustable on said uprights, said male electrodes being carried by crossmember and being laterally adjustable on said cross member and vertically adjustable by said uprights.
