Adjusting tool

Claim 2

A structure for accurately gauging line slack in a guide wire retrieval system including retrieved item connecting means, comprising a guide wire secured to fixed means at one end and to means movable between a first and a second position at its other end, said first position being closer than said second position to the fixed means end, guage means, for establishing a specific amount of guide wire slack with respect to the first position while the movable means is in its second position comprising a predetermined length of rigid material connected to the movable means and having apertured flanged means on its other end with the guide wire passing through the aperture, platform means attached to the guide wire at a point adjacent to the flange means and a ball bearing of low friction material interposed between the platform means and the flange means and held in such position by the tautness of the guide wire.

Claim 3

A structure as claimed in claim 1 wherein said gage means comprises a flat strip of material having right angled, oppositely turned end portions, one of said end portions having a notch in its edge for receiving said guide wire rope slidably therein, the other portion having an opening for engagement over a nut on said structure.

Claim 4

A structure as claimed in claim 1 wherein said gage means is formed of two sections adapted to slide on one another, one of said sections having an elongated slot therein and a fastening member piercing the other said section and adapted to ride in said slot whereby said sections may be slidably adjusted and tightened in selected positions.

Claim 5

A gage means as claimed in claim 3 wherein the outer end of each said section is turned substantially 90* and in opposite directions relative to each other, there being a notch in the outer end of each turned portion.

Claim 6

A tool as claimed in claim 3 wherein each section is formed of a flat strip of material.

Claim 7

A structure as set forth in claim 1 including propelling means associated with said movable means to exert a propelling force upon it when it is in the first position and means to arrest the application of the said propelling force.

Claim 8

A structure as set forth in claim 6 in which the propelling means is a tensioned spring and the arresting means is an explosive nut.

Claim 9

In combination with a missile launching shell including at least one extractor fixed to its inner wall for the separation of electrical umbilical cables from a missile when launched from said launching shell; said extractor comprising a supPorting member, a first bracket mounted to the upper end of said supporting member, a second bracket mounted on said supporting member ans spaced below said first bracket, an explosive nut mounted on said second bracket, a spring-loaded rod normally held in a cocked position by said explosive nut, a guide wire for attachment to said umbilical cables connected at one of its ends to said second bracket and being adjustably connected at its other end to said first bracket, said guide wire being retracted by release of said rod upon firing of said explosive nut to separate said umbilical cables from said missile, a platform member fixed at a predetermined point on said wire and a separable gage member of predetermined length having one end adapted to be hooked under said second bracket, its other end being flanged and adapted to engage said wire in advance of said platform member, a swage ball interposed between the platform member and the flange whereby the guide wire may be tensioned until said swage ball is firmly positioned and the slack in the guide wire is thereby established as the amount required by said umbilical cables for accurate separation from said missile.

Claim 10

In combination with a missile launching shell including at least one extractor fixed to its inner wall for the separation of electrical umbilical cables from a missile when launched from said launching shell; said extractor comprising a supPorting member, a first bracket mounted to the upper end of said supporting member, a second bracket mounted on said supporting member ans spaced below said first bracket, an explosive nut mounted on said second bracket, a spring-loaded rod normally held in a cocked position by said explosive nut, a guide wire for attachment to said umbilical cables connected at one of its ends to said second bracket and being adjustably connected at its other end to said first bracket, said guide wire being retracted by release of said rod upon firing of said explosive nut to separate said umbilical cables from said missile, a platform member fixed at a predetermined point on said wire and a separable gage member of predetermined length having one end adapted to be hooked under said second bracket, its other end being flanged and adapted to engage said wire in advance of said platform member, a swage ball interposed between the platform member and the flange whereby the guide wire may be tensioned until said swage ball is firmly positioned and the slack in the guide wire is thereby established as the amount required by said umbilical cables for accurate separation from said missile.
