Abstract
Abstract An electric storage battery assembly is formed of easily removable individual cell casing units. Each of the cell units is provided on alternate corner edges with vertical dovetail projecting ribs and dovetail grooves. The dovetail ribs and grooves provided on the edges of adjacent cell casings matingly and removably interengage. Conductor straps are provided to removably mechanically and electrically interconnect the electrode terminal posts of adjacent cell units in series arrangement. Longitudinal U-shaped channeled covers may be provided to slidably interlock with the conductor straps connecting adjacent cell casings. A cell casing lid provided with suitable openings and electrolyte-filling bosses is provided to cover and close the open top end of the cell casing. The lid may be provided on one side with a horizontal locking sleeve which removably interengages with a slidable transverse lug provided with a correspondingly shaped dovetail recess which matingly receives the dovetail shaped locking sleeve formed on the lid. This construction permits ready removal and replacement of defective cell units as well as flexibility in providing desired dimension configuration and electric output rating in the composite battery assembly by manufacturers, jobbers or distributors.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
A composite electric storage battery assembly comprising a plurality of removably interlocked individual cell casing units, each of said units being provided on alternate corner edges with vertical dovetail projecting ribs and dovetail grooves, the dovetail ribs and grooves of adjacent cell units matingly and removably interengaging with one another, a plurality of removable conductor straps mechanically and electrically interconnecting the electrode terminal posts of adjacent cell units in a series arrangement, each of said cell units being covered and closed by a lid provided with openings to receive the terminal posts of the cell unit and a screw threaded hollow boss to permit the filling of the cell with an electrolyte fluid, said boss being closed off by a correspondingly threaded mating filler cap, each of said lids having a horizontal rib which removably and matingly engages with a corresponding shaped recess formed in a horizontally slidable transverse lug.
Claim 2
Dependent Claim
150 words
A composite electric storage battery assembly comprising a plurality of removably interlocked individual cell casing units, each of said units being provided on alternate corner edges with vertical dovetail projecting ribs and dovetail grooves, the dovetail ribs and grooves of adjacent cell units matingly and removably interengaging with one another, a plurality of removable conductor straps mechanically and electrically interconnecting the electrode terminal posts of adjacent cell units in a series arrangement, each of said cell units being covered and closed by a lid provided with openings to receive the terminal posts of the cell unit and a screw threaded hollow boss to permit the filling of the cell with an electrolyte fluid, said boss being closed off by a correspondingly threaded mating filler cap, each of said lids having a horizontal rib which removably and matingly engages with a corresponding shaped recess formed in a horizontally slidable transverse lug.
Claim 3
Dependent Claim
41 words
A composite electric storage battery, as claimed in claim 1, further comprising a U-shaped channel cover to slidably removably engage and interlock with the connecting conductor straps for the electrode terminal posts located on one side of the adjacent cell units.
Claim 4
Dependent Claim
31 words
A composite electric storage battery, as claimed in claim 2, wherein U-shaped channel covers are provided to interlock with the connecting conductor straps on both sides of the adjacent cell units.
Claim 5
Dependent Claim
153 words
A composite electric storage battery assembly comprising a plurality of removably interlocked individual cell casing units, each of said units being provided on alternate corner edges with vertical dovetail projecting ribs and dovetail grooves, the dovetail ribs and grooves of adjacent cell units matingly and removably interengaging with one another, a plurality of removable conductor straps mechanically and electrically interconnecting the electrode terminal posts of adjacent cell units in a series arrangement, each of said cell units being covered and closed by a lid provided with openings to receive the terminal posts of the cell unit and a screw threaded hollow boss to permit the filling of the cell with an electrolyte fluid, said boss being closed off by a correspondingly threaded mating filler cap, a U-shaped channel cover to slidably removably engage and interlock with said conductor straps for the electrode terminal posts located on one side of the adjacent cell units.
Claim 6
Dependent Claim
153 words
A composite electric storage battery assembly comprising a plurality of removably interlocked individual cell casing units, each of said units being provided on alternate corner edges with vertical dovetail projecting ribs and dovetail grooves, the dovetail ribs and grooves of adjacent cell units matingly and removably interengaging with one another, a plurality of removable conductor straps mechanically and electrically interconnecting the electrode terminal posts of adjacent cell units in a series arrangement, each of said cell units being covered and closed by a lid provided with openings to receive the terminal posts of the cell unit and a screw threaded hollow boss to permit the filling of the cell with an electrolyte fluid, said boss being closed off by a correspondingly threaded mating filler cap, a U-shaped channel cover to slidably removably engage and interlock with said conductor straps for the electrode terminal posts located on one side of the adjacent cell units.
Claim 7
Dependent Claim
