Abstract
Abstract Nesting, pivoted bifurcated elements are mounted at one end of a elongated handle, and a remote-control linkage is provided whereby the elements can be forcibly spread apart to remove a radiator hose from the radiator neck. The opening of the inner element is tapered to accommodate various sizes of necks and hoses.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
181 words
A removal tool for automotive radiator hose comprising a bifurcated base adapted to fit over the neck of a radiator and to rest against the face of the radiator to which the neck is connected, said base comprising a pair of elements sufficiently spaced from each other that they may engage said face on either side of said neck and means connecting ends of said elements together; a bifurcated shoe comprising a heel and a pair of prongs spaced from each other and rigidly connected together by said heel, said prongs defining an opening adapted to slide over said neck and said prongs being adapted to engage the end of a hose on said neck, said shoe being capable of fitting between the elements of said base in the same orientation as said base in order to come within close proximity to the face of the radiator; means interconnecting said base and said shoe, and constraining said shoe for movement from between the elements of said base away from said face; and lever means for effecting said movement of said shoe.
Claim 2
Dependent Claim
181 words
A removal tool for automotive radiator hose comprising a bifurcated base adapted to fit over the neck of a radiator and to rest against the face of the radiator to which the neck is connected, said base comprising a pair of elements sufficiently spaced from each other that they may engage said face on either side of said neck and means connecting ends of said elements together; a bifurcated shoe comprising a heel and a pair of prongs spaced from each other and rigidly connected together by said heel, said prongs defining an opening adapted to slide over said neck and said prongs being adapted to engage the end of a hose on said neck, said shoe being capable of fitting between the elements of said base in the same orientation as said base in order to come within close proximity to the face of the radiator; means interconnecting said base and said shoe, and constraining said shoe for movement from between the elements of said base away from said face; and lever means for effecting said movement of said shoe.
Claim 3
Dependent Claim
181 words
A removal tool for automotive radiator hose comprising a bifurcated base adapted to fit over the neck of a radiator and to rest against the face of the radiator to which the neck is connected, said base comprising a pair of elements sufficiently spaced from each other that they may engage said face on either side of said neck and means connecting ends of said elements together; a bifurcated shoe comprising a heel and a pair of prongs spaced from each other and rigidly connected together by said heel, said prongs defining an opening adapted to slide over said neck and said prongs being adapted to engage the end of a hose on said neck, said shoe being capable of fitting between the elements of said base in the same orientation as said base in order to come within close proximity to the face of the radiator; means interconnecting said base and said shoe, and constraining said shoe for movement from between the elements of said base away from said face; and lever means for effecting said movement of said shoe.
Claim 4
Dependent Claim
181 words
A removal tool for automotive radiator hose comprising a bifurcated base adapted to fit over the neck of a radiator and to rest against the face of the radiator to which the neck is connected, said base comprising a pair of elements sufficiently spaced from each other that they may engage said face on either side of said neck and means connecting ends of said elements together; a bifurcated shoe comprising a heel and a pair of prongs spaced from each other and rigidly connected together by said heel, said prongs defining an opening adapted to slide over said neck and said prongs being adapted to engage the end of a hose on said neck, said shoe being capable of fitting between the elements of said base in the same orientation as said base in order to come within close proximity to the face of the radiator; means interconnecting said base and said shoe, and constraining said shoe for movement from between the elements of said base away from said face; and lever means for effecting said movement of said shoe.
Claim 5
Dependent Claim
34 words
A tool according to claim 1 in which the spacing between said prongs gradually decreases from their ends toward said heel thereby providing a tapered opening capable of accommodating various sizes of radiator necks.
Claim 6
Dependent Claim
29 words
A tool according to claim 1 including an elongated handle fastened to said base so that it extends substantially parallel to a face when engaged by saiD base elements.
Claim 7
Dependent Claim
83 words
A tool according to claim 1 including an elongated handle fastened to said base so that it extends substantially parallel to a radiator face when said face is engaged by said base elements, and wherein said lever means comprises a lever arm pivoted on said handle at a location remote from said base and a linkage operable by said lever arm and connected to said shoe to effect movement of said shoe from between the elements of said base away from said face.
Claim 8
Dependent Claim
29 words
A tool according to claim 1 in which said interconnecting means comprises means pivoting the heel of said shoe to the means connecting ends of said base elements together.
Claim 9
Dependent Claim
44 words
A tool according to claim 1 in which said interconnecting means comprises means pivoting the heel of said shoe to the means connecting ends of said base elements together, and in which the side of said shoe away from the radiator face is convex.
