Abstract
Abstract A device for removing and inserting traction drive batteries in lift trucks, the device being supported upon the floor aside the lift truck and engageable with a body portion thereof for maintaining a fixed position in relation to the truck during operation of the device. A handle bar lever arm is pivoted from the base and connectible by means of a ratchet bar to a side of the battery for extracting or inserting the battery from or in a truck compartment by a succession of movements in which the lever arm is successively adjusted about its base pivot to engage different ones of a plurality of longitudinally spaced notches in the ratchet bar for moving the battery in or out of the compartment.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
242 words
A battery extractor comprising an elongated base assembly adapted to abut at one end thereof the side of a vehicle, an elongated actuator handle bar pivoted from the end of the base assembly opposite the end which abuts the vehicle, an elongated ratchet bar connectible to a battery in a battery compartment of the vehicle at one end and to said handle bar at a plurality of adjustment positions thereof, said ratchet bar extending above and longitudinally of the base assembly and said handle bar being manually actuatable in both directions about its pivot connection to said base assembly at each adjustment position of said ratchet bar for extracting and inserting the battery from and into the battery compartment, and wherein said handle bar includes a pair of elongated side members having an opening therebetween in the area of said ratchet bar, a member connecting the sides of said handle bar through said opening, said ratchet bar having a plurality of notches spaced longitudinally of the lower side thereof engageable successively by said connecting member, said handle bar being pivotable in said both directions at each position of engagement with said ratchet bar, and wherein the remote end of said ratchet bar is connected to battery bracket means, successive pivotal movement in one direction from successive positions of adjustment of said handle bar in relation to said ratchet bar effecting an extraction of the battery from the vehicle onto said base assembly.
Claim 2
Dependent Claim
242 words
A battery extractor comprising an elongated base assembly adapted to abut at one end thereof the side of a vehicle, an elongated actuator handle bar pivoted from the end of the base assembly opposite the end which abuts the vehicle, an elongated ratchet bar connectible to a battery in a battery compartment of the vehicle at one end and to said handle bar at a plurality of adjustment positions thereof, said ratchet bar extending above and longitudinally of the base assembly and said handle bar being manually actuatable in both directions about its pivot connection to said base assembly at each adjustment position of said ratchet bar for extracting and inserting the battery from and into the battery compartment, and wherein said handle bar includes a pair of elongated side members having an opening therebetween in the area of said ratchet bar, a member connecting the sides of said handle bar through said opening, said ratchet bar having a plurality of notches spaced longitudinally of the lower side thereof engageable successively by said connecting member, said handle bar being pivotable in said both directions at each position of engagement with said ratchet bar, and wherein the remote end of said ratchet bar is connected to battery bracket means, successive pivotal movement in one direction from successive positions of adjustment of said handle bar in relation to said ratchet bar effecting an extraction of the battery from the vehicle onto said base assembly.
Claim 3
Dependent Claim
29 words
A battery extractor as claimed in claim 1 wherein said base assembly includes elevated roller means for supporting the battery on the base assembly during extraction and insertion thereof.
Claim 4
Dependent Claim
45 words
A battery extractor as claimed in claim 1 wherein the vehicle is a lift truck having a battery mounted in a compartment transverse of the truck, said battery extractor being operative in a generally transverse position to the truck in line with the battery compartment.
Claim 5
Dependent Claim
46 words
A battery extractor as claimed in claim 1 wherein stop means is adapted to be mounted on said base assembly at different longitudinal locations adjacent the handle bar end of the base assembly for limiting variously the distance of extraction of the battery from the vehicle.
Claim 6
Dependent Claim
192 words
A battery extractor comprising an elongated base assembly adapted to abut at one end thereof the side of a vehicle, an elongated actuator handle bar pivoted from the end of the base assembly opposite the end which abuts the vehicle, an elongated ratchet bar connectible to a battery in a battery compartment of the vehicle at one end and to said handle bar at a plurality of adjustment positions thereof, said ratchet bar extending above and longitudinally of the base assembly and said handle bar being manually actuatable in both directions about its pivot connection to said base assembly at each adjustment position of said ratchet bar for extracting and inserting the battery from and into the battery compartment, the vehicle abutting end of said base assembly including means enabling the base assembly to be tilted upwardly at the handle bar end thereof for insertion of the opposite end beneath a side portion of the vehicle, lowering thereof from said tilted position effecting a connection of the base assembly to the side of the vehicle preventing longitudinal movement of the base assembly in either direction during extraction and insertion of a battery.
Claim 7
Dependent Claim
192 words
A battery extractor comprising an elongated base assembly adapted to abut at one end thereof the side of a vehicle, an elongated actuator handle bar pivoted from the end of the base assembly opposite the end which abuts the vehicle, an elongated ratchet bar connectible to a battery in a battery compartment of the vehicle at one end and to said handle bar at a plurality of adjustment positions thereof, said ratchet bar extending above and longitudinally of the base assembly and said handle bar being manually actuatable in both directions about its pivot connection to said base assembly at each adjustment position of said ratchet bar for extracting and inserting the battery from and into the battery compartment, the vehicle abutting end of said base assembly including means enabling the base assembly to be tilted upwardly at the handle bar end thereof for insertion of the opposite end beneath a side portion of the vehicle, lowering thereof from said tilted position effecting a connection of the base assembly to the side of the vehicle preventing longitudinal movement of the base assembly in either direction during extraction and insertion of a battery.
Claim 8
Dependent Claim
