Abstract
Abstract A lifting tool for batteries and the like includes first and second members each having an upright end leg provided with a gripping shoe. The leg of the first member merges into a horizontal handle, while the leg of the second member merges into a connecting portion which extends under the handle of the first member and is connected to the leg of the first member at a pivot pin. This enables the two members to pivot relative to each other. The pivot pin extends through a slot in the connecting portion of the second member to permit the two sections to shift relative to each other to vary the spacing between the gripping shoes. The legs are spread apart by pressing the handle toward the connecting portion, and in this condition the tool is installed over the object to be lifted with the shoes opposite the end walls of the object. When the tool is lifted upwardly at its handle, the gripping legs move together, causing the shoes to bear against the end walls of the object. The weight of the object coupled with the leverage developed between the gripping members results in a sizeable gripping force on the object.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
320 words
A tool for lifting a battery or other object having upright walls, said tool comprising: a first gripping member in the form of a rigid and unitary structure having an upright end leg and a handle extended from the upper end of the end leg with the handle being presented at an angle to that end leg, the end leg having a gripping surface at its lower end; a second gripping member in the form of a rigid and unitary structure having an upright end leg and a connecting portion extended generally horizontally from the upper end of that end leg and being located below the handle on the first gripping member, the end leg of the second gripping member having a gripping surface at its lower end with that gripping surface being located opposite the gripping surface on the end leg of the first member, the connecting portion of the second member being located adjacent to the end leg of the first member where the connecting portion is provided with a slot and a plurality of spaced apart notches which open into the slot, the slot extending in the direction of the connecting portion; and a pin extended through the slot in the connecting portion and secured in the end leg of first member, the pin being sized to fit in the notches of the slots to enable the first member to pivot relative to the second member at any one of the notches, whereby an upwardly directed force exerted on the handle will cause the gripping surfaces of the two gripping members to move together so that the battery may be clamped between them, the pin further being sized to slide along the slot from one notch to the other so that the spacing between the end legs of the two gripping members may be varied, whereby the tool may be adjusted to accommodate batteries of varying widths.

A tool for lifting a battery or other object having upright walls, said tool comprising: a first gripping member in the form of a rigid and unitary structure having an upright end leg and a handle extended from the upper end of the end leg with the handle being presented at an angle to that end leg, the end leg having a gripping surface at its lower end; a second gripping member in the form of a rigid and unitary structure having an upright end leg and a connecting portion extended generally horizontally from the upper end of that end leg and being located below the handle on the first gripping member, the end leg of the second gripping member having a gripping surface at its lower end with that gripping surface being located opposite the gripping surface on the end leg of the first member, the connecting portion of the second member being located adjacent to the end leg of the first member where the connecting portion is provided with a slot and a plurality of spaced apart notches which open into the slot, the slot extending in the direction of the connecting portion; and a pin extended through the slot in the connecting portion and secured in the end leg of first member, the pin being sized to fit in the notches of the slots to enable the first member to pivot relative to the second member at any one of the notches, whereby an upwardly directed force exerted on the handle will cause the gripping surfaces of the two gripping members to move together so that the battery may be clamped between them, the pin further being sized to slide along the slot from one notch to the other so that the spacing between the end legs of the two gripping members may be varied, whereby the tool may be adjusted to accommodate batteries of varying widths.
Claim 3
Dependent Claim
61 words
A tool according to claim 1 wherein the first gripping member further includes a gripping shoe attached to the lower end of its upright leg, and the second gripping member further includes a gripping shoe attached to the lower end of its upright leg, the two gripping shoes being wider than their respective end legs and having the gripping surfaces thereon.
Claim 4
Dependent Claim
18 words
A tool according to claim 2 wherein each gripping surface is composed of a plurality of horizontal grooves.
Claim 5
Dependent Claim
14 words
A tool according to claim 1 wherein the notches open downwardly into the slot.
Claim 6
Dependent Claim
145 words
A tool according to claim 1 wherein the first and second gripping members are formed from bar stock of rectangular cross-sectional configuration, whereby the first and second gripping members have major and minor surface areas; and wherein the major surface areas of the handle are presented horizontally; wherein the major surface areas of the upright leg on the first member at the lower end thereof are presented vertically and generally normal to the longitudinal axes of the handle; wherein the upright leg of the first member is twisted intermediate its ends so that the major surface areas of the twisted portion are oriented 90° with respect to the major surface areas at the lower end; and wherein the connecting portion of the second member extends across the twisted portion of the upright leg on the first member and has its major surface areas oriented vertically.
Claim 7
Dependent Claim
41 words
A tool according to claim 5 wherein the bar stock of the connecting portion is twisted near the end leg of the second gripping member such that the major surface areas of the connecting portion beyond the twist are presented horizontally.
Claim 8
Dependent Claim
36 words
A tool according to claim 6 wherein the major surface areas of the bar stock in the end leg of the second gripping member are presented parallel to the gripping surface for the second gripping member.
Claim 9
Dependent Claim
51 words
A tool according to claim 1 and further comprising a compression spring attached to the handle of the first member and extended downwardly therefrom toward the connecting portion of the second member, the lower end of the spring being aligned with, yet detached from, the connecting portion of the second member.
Claim 10
Dependent Claim
38 words
A tool according to claim 1 wherein the pin has a head which overlies the connecting portion of the second gripping member and is large enough to prevent the pin from passing out of the slot and notches.
Claim 11
Dependent Claim
