Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
64 words
A lead storage battery having terminals made of lead and characterized in that; the terminals have inserts made of metal having lower electrical resistance and higher mechanical strength than lead, the inserts having a portion protruding from the top of the terminal, the protruding portion being in the shape of a tubular loop with axis at an angle to the axis of the terminal.
Claim 2
Dependent Claim
64 words
A lead storage battery having terminals made of lead and characterized in that; the terminals have inserts made of metal having lower electrical resistance and higher mechanical strength than lead, the inserts having a portion protruding from the top of the terminal, the protruding portion being in the shape of a tubular loop with axis at an angle to the axis of the terminal.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein the axis of the tubular loop is substantially at right angles to the axis of the terminal.
Claim 4
Dependent Claim
15 words
The apparatus of claim 2 wherein the insert including the tubular loop is of copper.
Claim 5
Dependent Claim
15 words
The apparatus of claim 2 wherein the insert including the tubular loop is of aluminum.
Claim 6
Dependent Claim
25 words
The apparatus of claim 2 wherein the portion of the insert within the terminal is provided with apertures penetrated by the lead of the terminal.
Claim 7
Dependent Claim
20 words
The apparatus of claim 2 wherein the portion of the insert within the lead terminal is provided with lateral protrusions.
Claim 8
Dependent Claim
27 words
The apparatus of claim 2 further comprising a flexible cable having an end portion with insulation stripped off, the end portion being crimped in the tubular loop.
Claim 9
Dependent Claim
35 words
The apparatus of claim 7 further comprising a slotted collar surrounding the terminal and the cable crimped in the tubular segment, the space within the collar being filled with a cast block of insulating material.
Claim 10
Dependent Claim
17 words
The apparatus of claim 8 wherein the cast block also covers the exposed surface of the terminal.
Claim 11
Dependent Claim
15 words
The apparatus of claim 1 wherein the insert extends substantially coaxially into the lead terminal.
Claim 12
Dependent Claim
21 words
The apparatus of claim 7 wherein the crimping is such as to compress the tubular loop into a horizontally elongated configuration.
