Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
187 words
An aerial device in combination with an object transportable along a line elevated above a surface, the improvement comprising: a. support means intended for releasably gripping the object, said support means being born by the elevated line, said support means comprising a first member engaging the object toward one end thereof; a second member engaging the object toward the other end thereof, said second member including confining means for restricting the distance between said first member and said second member, said first and second members acting in concert by said engagements to effect the intended support of the object; and spring means for urging gripping engagement of the object by said first and second members, said urging engagement of said spring means guided by said confining means, said spring means allowing disengagement of the object by said first and second members; b. traveling means intended for carrying the object along the elevated line; c. trigger means for initiating the release of said support means gripping the object, thereby overcoming the spring force of said spring means urging engagment of the object by said first and second members.
Claim 2
Dependent Claim
187 words
An aerial device in combination with an object transportable along a line elevated above a surface, the improvement comprising: a. support means intended for releasably gripping the object, said support means being born by the elevated line, said support means comprising a first member engaging the object toward one end thereof; a second member engaging the object toward the other end thereof, said second member including confining means for restricting the distance between said first member and said second member, said first and second members acting in concert by said engagements to effect the intended support of the object; and spring means for urging gripping engagement of the object by said first and second members, said urging engagement of said spring means guided by said confining means, said spring means allowing disengagement of the object by said first and second members; b. traveling means intended for carrying the object along the elevated line; c. trigger means for initiating the release of said support means gripping the object, thereby overcoming the spring force of said spring means urging engagment of the object by said first and second members.
Claim 3
Dependent Claim
47 words
The aerial device of claim 1 in which said trigger means comprises an abutment fixed on the elevated line which selectively contacts said first and second members and provides a force that overcomes said spring means urging engagement of the object by said first and second members.
Claim 4
Dependent Claim
40 words
The aerial device of claim 2 in which said traveling means includes at least one open loop fastened to said support means and slidable along the elevated line and propelling means intended for moving the object along the elevated line.
Claim 5
Dependent Claim
36 words
The aerial device of claim 1 which additionally comprises flight means intended for interrupting the gravitational descent of the object from the elevated line to the surface after release of the object by said support means.
Claim 6
Dependent Claim
47 words
The aerial device of claim 4 in which said trigger means comprises an abutment fixed on the elevated line which selectively contacts said first and second members and provides a force that overcomes said spring means urging engagement of the object by said first and second members.
Claim 7
Dependent Claim
40 words
The aerial device of claim 5 in which said traveling means includes at least one open loop fastened to said support means and slidably along the elevated line and propelling means intended for moving the object along the elevated line.
Claim 8
Dependent Claim
31 words
The aerial device of claim 6 in which said flight means comprises parachute means intended for holding the object and intended for arresting the descent of the object to the surface.
Claim 9
Dependent Claim
34 words
The aerial device of claim 7 in which said propelling means comprises parachute means intended for pulling the object along the elevated line, said parachute means and the object connected to swivel means therebetween.
