Abstract
Abstract A two-part molded cartridge utilizes one part as an assembly tray or shell for assembling three electric cells in position to permit electrical interconnections between the cells, and to support contact terminal surfaces for connection to external circuit contact terminals, and then utilizes the second molded part as a cover, and the two parts are then sealed to constitute a housing for the cells as a battery unit.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
182 words
A battery comprising a two-part casing consisting of a pair of co-fitting molded trays elongate along longitudinal axis and each tray having a plurality of recesses, (for respectively receiving and accommodating) each unit primary cell of predetermined thickness with spaced bottom terminal and top terminal surfaces placed in each of said recesses, said recesses in said trays being disposed effectively relatively parallel in sequence and transverse tO said axis at an angle such that the bottom terminal surface of a prior cell in the sequence of said recesses when inserted in its recess in one tray, is substantially co-planar with the top terminal surface of the next succeeding cell in said sequence of said recesses; and electrically conductive means electrically connecting the bottom terminal surface of a forward cell, in said sequence of recesses, to the top terminal surface of a subsequent cell in said sequence; said pair of molded trays being shaped to be engageable and mateable at relatively planar surfaces on each molded tray with corresponding related and facing recesses in said trays cooperating to enclose each unit primary cell.
Claim 2
Dependent Claim
182 words
A battery comprising a two-part casing consisting of a pair of co-fitting molded trays elongate along longitudinal axis and each tray having a plurality of recesses, (for respectively receiving and accommodating) each unit primary cell of predetermined thickness with spaced bottom terminal and top terminal surfaces placed in each of said recesses, said recesses in said trays being disposed effectively relatively parallel in sequence and transverse tO said axis at an angle such that the bottom terminal surface of a prior cell in the sequence of said recesses when inserted in its recess in one tray, is substantially co-planar with the top terminal surface of the next succeeding cell in said sequence of said recesses; and electrically conductive means electrically connecting the bottom terminal surface of a forward cell, in said sequence of recesses, to the top terminal surface of a subsequent cell in said sequence; said pair of molded trays being shaped to be engageable and mateable at relatively planar surfaces on each molded tray with corresponding related and facing recesses in said trays cooperating to enclose each unit primary cell.
Claim 3
Dependent Claim
78 words
A battery, as in claim 1, comprising, additionally, an integral hinge link between the two related trays of a casing, to permit the two trays to be held open during insertion and placement of the individual cells in their respective recesses, and then to permit and guide subsequent hingeing movement of the two trays to accomplish the operation of properly mating the two trays to permit them to be sealed as a closed casing for the enclosed cells.
Claim 4
Dependent Claim
39 words
A battery, as in claim 2, comprising, additionally, integrally formed locating pins on the mating face of one of said trays, and pin-receiving holes in the other tray for receiving said pins to mate the two trays as pre-designed.
Claim 5
Dependent Claim
67 words
A battery, as in claim 1, in which said connecting conducting means consists of a thin metallic strip, welded at one end to the bottom terminal surface of a forward cell in said sequence, and disposed to be placeable parallel to, and to engage, the top terminal surface of the subsequent cell in said sequence, to which the strip is to be and is welded during assembly.
Claim 6
Dependent Claim
69 words
A battery, as in claim 4, in which the front cell in said sequence is provided with a terminal element connected to the top terminal surface of said front cell in said sequence, with said terminal element extending through an aperture in a wall of said first tray and lying disposed on an outer surface of said first tray to be accessible for connection to an external electric circuit.
Claim 7
Dependent Claim
58 words
A battery, as in claim 4, in which said first tray is provided with two integrally formed bosses respectively protruding inwardly and respectively from the two side walls and extending to a distance just short of the locus of the plane occupied by each of said metallic connecting strips, to substantially confine said strips to their respective loci.
Claim 8
Dependent Claim
93 words
A battery as in claim 6, in which each cell embodies a conducting cylindrical outer shell of one polarity and has its top terminal surface of opposite polarity concentrically disposed within said outer shell adjacent the front axial end of said outer shell and is electrically insulated from said outer shell; and one of said protruding bosses disposed under its related conducting strip has sufficient projection to serve to prevent the related conducting strip from engaging the conductive outer shell of the cell to whose top terminal surface the conducting strip is connected.
Claim 9
Dependent Claim
62 words
A battery, as in claim 7, in which each conducting metal strip to the top terminal surface of a cell after the front cell is exposed outside the recess for the cell in assembly, to enable each said metal strip to be welded to its related top terminal surface by a simple two-prong welding tool in the manufacturing operations for said battery.
Claim 10
Dependent Claim
54 words
A battery, as in claim 5, in which the wall of the two-part casing adjacent the last or final cell in said sequence is opened to expose the bottom terminal surface of said last or final cell in said sequence to permit electrical contact to be made thereto through said wall of said casing.
Claim 11
Dependent Claim
91 words
A molded battery container having a hollow peripheral shell with said peripheral shell having one end opening and with said peripheral shell including discrete cell chambers therein; a cell positioned in each discrete cell chamber; Said cells having an offset relationship with each other, the bottom surface of one cell overlies the next cell, and being insulated each from its neighbor; a plurality of electrical connections between each of the cells to give a serial output voltage and output terminal connectors including one of said cells for obtaining an output therefrom.
Claim 12
Dependent Claim
91 words
A molded battery container having a hollow peripheral shell with said peripheral shell having one end opening and with said peripheral shell including discrete cell chambers therein; a cell positioned in each discrete cell chamber; Said cells having an offset relationship with each other, the bottom surface of one cell overlies the next cell, and being insulated each from its neighbor; a plurality of electrical connections between each of the cells to give a serial output voltage and output terminal connectors including one of said cells for obtaining an output therefrom.
Claim 13
Dependent Claim
79 words
A molded battery container having a hollow peripheral shell containing individual cells therein, said shell being adapted to retain the edges of the cells in relationship one to the other in slightly overlapped planes and substantially immovable therein and electrically insulated from each other; electrical connector means between said cells in series giving a desired output voltage; one of said cells being a first output terminal for said output voltage; and said peripheral shell including a second output terminal.
Claim 14
Dependent Claim
79 words
A molded battery container having a hollow peripheral shell containing individual cells therein, said shell being adapted to retain the edges of the cells in relationship one to the other in slightly overlapped planes and substantially immovable therein and electrically insulated from each other; electrical connector means between said cells in series giving a desired output voltage; one of said cells being a first output terminal for said output voltage; and said peripheral shell including a second output terminal.
Claim 15
Dependent Claim
16 words
The molded battery container of claim 11 wherein the hollow peripheral shell is an enclosing housing.
