Abstract
Abstract To manufacture an electric storage battery of the kind including a battery box divided into a plurality of compartments, a lid closing the battery box, an assembly of battery plates and separators within each compartment, means interconnecting plates within adjacent compartments so that the assemblies within the compartments are connected in series, and a pair of posts extending upwardly from the assemblies in the end compartments through apertures in the lid, a pair of sleeve parts are first located in position relative to each aperture in the lid so that the sleeve parts extend into their respective aperture. Each pair of sleeve parts are then secured together by resistance welding to produce a sleeve extending through each aperture in the lid, whereafter the posts are secured to the sleeves respectively.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
133 words
A method of manufacturing an electric storage battery of the kind including a battery box divided into a plurality of compartments, a lid closing the battery box, an assembly of battery plates and separators within each compartment, means interconnecting plates within adjacent compartments so that the assemblies within the compartments are connected in series, and a pair of posts extending upwardly from the assemblies in the end compartments through apertures in the lid, the method comprising the steps of locating a pair of sleeve parts in position relative to each aperture in the lid so that the sleeve parts extend into their respective aperture, securing each pair of sleeve parts together by resistance welding to produce a sleeve extending through each aperture in the lid, and securing the posts to the sleeves respectively.
Claim 2
Independent Claim
133 words
A method of manufacturing an electric storage battery of the kind including a battery box divided into a plurality of compartments, a lid closing the battery box, an assembly of battery plates and separators within each compartment, means interconnecting plates within adjacent compartments so that the assemblies within the compartments are connected in series, and a pair of posts extending upwardly from the assemblies in the end compartments through apertures in the lid, the method comprising the steps of locating a pair of sleeve parts in position relative to each aperture in the lid so that the sleeve parts extend into their respective aperture, securing each pair of sleeve parts together by resistance welding to produce a sleeve extending through each aperture in the lid, and securing the posts to the sleeves respectively.
Claim 3
Dependent Claim
22 words
A method as claimed in claim 1 wherein a removable former is received within each pair of sleeves during the resistance welding.
Claim 4
Dependent Claim
61 words
A method as claimed in claim 1 wherein the wall of each aperture in the lid is formed with an integral projecting shoulder, each shoulder dividing its aperture into an upper and a lower recess on opposite sides of said shoulder respectively and each pair of sleeve parts are located in the upper and lower recesses respectively of its respective aperture.
Claim 5
Dependent Claim
46 words
A method as claimed in claim 3 wherein each shoulder has aN inwardly directed face formed with integral longitudinal splines around which material from the respective pair of sleeve parts flows during the resistance welding to enhance the key between the shoulder and the sleeve parts.
Claim 6
Dependent Claim
46 words
A method as claimed in claim 3 wherein each of said sleeve parts is formed with an integral sealing ring which is pushed into the shoulder of the respective aperture when the sleeve parts are resistance welded together to produce the sleeve extending through the aperture.
Claim 7
Dependent Claim
40 words
A method as claimed in claim 3 wherein each shoulder is formed on a pair of opposite faces with respective integral sealing rings, the sealing rings engaging the sleeve parts when the sleeve parts are engaged in their respective recesses.
Claim 8
Dependent Claim
14 words
A method as claimed in claim 3 wherein said recesses are of non-circular cross-section.
Claim 9
Dependent Claim
105 words
A method as claimed in claim 7 wherein the upper and lower parts constituting each sleeve are in the form of first and second non-circular nuts respectively, the nuts being complementary with their respective recesses and each first nut having an upwardly extending axial flange which protrudes from the top of said lid when the nut is engaged in its respective upper recess and each second nut having an upwardly extending cylindrical portion which, when the nut is received in the lower recess of its respective aperture, extends into the region of the aperture defined within the shoulder to engage its associated upper sleeve part.
Claim 10
Dependent Claim
51 words
A method as claimed in claim 8 wherein each first nut has a downwardly extending cylindrical portion which projects into the region of its respective aperture defined within the shoulder to engage the upwardly extending cylindrical portion of its associated second nut when the nuts are located in their respective recesses.
Claim 11
Dependent Claim
52 words
A method as claimed in claim 8 wherein at least one of the nuts has the face thereof which is to be presented to its respective recess inclined outwardly so that the thickness of the nut at the periphery thereof is greater than the thickness of the nut adjacent the centre thereof.
Claim 12
Dependent Claim
23 words
A method as claimed in claim 4 wherein each upper recess is of non-circular cross-section and each lower recess is of circular cross-section.
Claim 13
Dependent Claim
94 words
A method as claimed in claim 11 wherein the upper part of each of said sleeves is engaged in a respective upper recess and comprises a non-circular nut having an upwardly extending axial flange which then protrudes from the top of said lid, and wherein the lower part of each of said sleeves is engaged in a respective lower recess and comprises a circular nut having an upwardly extending cylindrical portion which then extends into the region of its respective aperture defined within the shoulder so as to engage its associated upper sleeve part.
Claim 14
Dependent Claim
57 words
A method as claimed in claim 12 wherein the upper part of each of said sleeves also comprises a downwardly extending cylindrical portion which projects into the region of its respective aperture defined within the shoulder to engage the upwardly extending cylindrical portion of its associated lower sleeve when the parts are engaged in their respective recesses.
Claim 15
Dependent Claim
52 words
A method as claimed in claim 12 wherein at least one of the nuts has the face thereof which is to be presented to its respective recess inclined outwardly so that the thickness of the nut at the periphery thereof is greater than the thickness of the nut adjacent the centre thereof.
