Abstract
Abstract A battery terminal mounted on a battery post has a cylindrically shaped post fitting, clamping members, a cable connector, and a tightening tool. The cable connector is formed by bending a vertically oriented metal band. Post fitting and clamping members are formed from a vertically oriented metal band, such that the clamping members are connected to the free ends of the post fitting. The clamping members 18A, 18B are further bent to provide sliding surfaces matching the tapers of the tightening tool. By tightening a bolt down from above, the clamping members are moved horizontally together, and the free ends of the post fitting are thus closed to clamp the battery post.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
A battery terminal mounted on a battery post, comprising: a cable connector adapted for connection with an electrical cable; an annular post fitting formed by bending a vertically oriented metal band in an arc to form a vertically oriented cylindrical shape, and having open free ends; first and second clamping members contiguous to said open free ends of the post fitting, and formed by end portions of said vertically oriented metal band, said first and second clamping members having tapered sliding surfaces; a tightening tool comprising tapered surfaces fitting over said tapered sliding surfaces; a nut positioned inside the clamping members; said first and second clamping members having jam walls, respectively, for preventing nut rotation; and a bolt passed through the tightening tool and tightened into the nut to move the tightening tool towards said first and second clamping members, thereby closing the first and second clamping members, and in turn, closing the free ends of the post fitting to firmly clamp the battery terminal to the battery post.
Claim 2
Dependent Claim
169 words
A battery terminal mounted on a battery post, comprising: a cable connector adapted for connection with an electrical cable; an annular post fitting formed by bending a vertically oriented metal band in an arc to form a vertically oriented cylindrical shape, and having open free ends; first and second clamping members contiguous to said open free ends of the post fitting, and formed by end portions of said vertically oriented metal band, said first and second clamping members having tapered sliding surfaces; a tightening tool comprising tapered surfaces fitting over said tapered sliding surfaces; a nut positioned inside the clamping members; said first and second clamping members having jam walls, respectively, for preventing nut rotation; and a bolt passed through the tightening tool and tightened into the nut to move the tightening tool towards said first and second clamping members, thereby closing the first and second clamping members, and in turn, closing the free ends of the post fitting to firmly clamp the battery terminal to the battery post.
Claim 3
Dependent Claim
170 words
A battery terminal mounted on a battery post, comprising: a cable connector adapted for connection with an electrical cable; an annular post fitting formed by bending a vertically oriented metal band in an arc to form a vertically oriented cylindrical shape, and having open free ends; first and second clamping members contiguous to said open free ends of the post fitting, and formed by end portions of said vertically oriented metal band, said first and second clamping members having tapered sliding surfaces; a tightening tool comprising tapered surfaces fitting over said tapered sliding surfaces; a nut positioned inside the clamping members; said first and second clamping members having claws, respectively, for being engaged with said nut; and a bolt passed through the tightening tool and tightened into the nut to move the tightening tool towards said first and second clamping members, thereby closing the first and second clamping members, and in turn, closing the free ends of the post fitting to firmly clamp the battery terminal to the battery post.
