Abstract
Abstract A battery changing apparatus for replacing a spent battery with a charged one on an electrically powered vehicle including a support with at least two battery support sections for supporting batteries adapted for use on an electrically powered vehicle. A spent battery is removed from the vehicle and transferred to one of the support sections. The relative positions of the apparatus for removing and transferring the battery and the support can be changed so that a charged battery can be removed from another support section. The apparatus for removing and transferring the battery can remove the charged battery from the other support and transfer it to the vehicle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
A battery changing apparatus for replacing a spent battery with a charged one, which is particularly suitable for servicing electrically powered vehicles in an underground mine, comprising: a turntable having a stationary base, and a support rotatably mounted on said base and having two or more battery receiving and supporting stations; a battery transfer means located in association with the turntable and having elevatable means for lifting a battery free of a vehicle or battery support station and reciprocatory means for moving said elevatable means into position relative to the turntable wherein said elevatable means can lower said battery into one of said battery support stations, wherein said battery transfer means can be used alternatively for lifting a battery free of the turntable support, moving it into position relative to a vehicle and lowering it onto said vehicle; and means for selectively rotating the turntable to position a selected battery support station in assocation with the battery transfer means.
Claim 2
Dependent Claim
159 words
A battery changing apparatus for replacing a spent battery with a charged one, which is particularly suitable for servicing electrically powered vehicles in an underground mine, comprising: a turntable having a stationary base, and a support rotatably mounted on said base and having two or more battery receiving and supporting stations; a battery transfer means located in association with the turntable and having elevatable means for lifting a battery free of a vehicle or battery support station and reciprocatory means for moving said elevatable means into position relative to the turntable wherein said elevatable means can lower said battery into one of said battery support stations, wherein said battery transfer means can be used alternatively for lifting a battery free of the turntable support, moving it into position relative to a vehicle and lowering it onto said vehicle; and means for selectively rotating the turntable to position a selected battery support station in assocation with the battery transfer means.
Claim 3
Dependent Claim
13 words
The apparatus of claim 1, wherein the turntable has three battery support sections.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2, wherein the turntable includes a triangular frame and support section portions connected at each corner of the frame, the portions being spaced apart and each one including a ledge for holding lugs projecting from the sides of a battery casing located between spaced-apart portions.
Claim 5
Dependent Claim
170 words
A battery changing apparatus for replacing a spent battery with a charged one, which is particularly suitable for sevicing electrically powered vehicles in an underground mine, comprising: a turntable having a stationary base, and a support rotatably mounted on said base and having two or more battery receiving and supporting stations; a battery transfer means located in association with the turntable for lifting a battery free of a vehicle, moving it into position relative to the turntable and lowering it into one of said battery support stations or alternatively for lifting a battery free of the turntable support, moving it into position relative to a vehicle and lowering it onto said vehicle, said reciprocating battery transfer means includes a platform, means for selectively raising and lowwering the platform, and means for selectively moving the platform from an inner position adjacent the turntable to an outer position adjacent a vehicle; and means for selectively rotating the turntable to position a selected battery support station in association with the battery transfer means.
Claim 6
Dependent Claim
