Abstract
Abstract Apparatus for binding a load of articles including an elongate cable extending about the load, and a spring-loaded device operatively interconnecting opposite ends of the cable. A cable take-up drum is provided to adjust the effective length of the cable extending about the load and to deflect the spring to provide selected tightening of the cable about the load. Should the load change configuration the spring maintains the cable taut about the load.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
Apparatus for binding a group of articles comprising an elongate flexible element which may extend about such articles, a takeup device for taking up a portion of such flexible element to reduce the effective length of said element, an elongate spring, an elongate spring guide, one end of which is operatively connected to said takeup device, within which said spring is mounted, an abutment, formed at the other end of said guide, which one end of said spring engages, a head secured to the other end of said flexible element, which head extends into said guide to engage the end of said spring opposite its abutment-engaging end to compress said spring when urged toward said abutment, and limiting means interposed between said head and said abutment operable to limit the deflection of said spring.
Claim 2
Dependent Claim
134 words
Apparatus for binding a group of articles comprising an elongate flexible element which may extend about such articles, a takeup device for taking up a portion of such flexible element to reduce the effective length of said element, an elongate spring, an elongate spring guide, one end of which is operatively connected to said takeup device, within which said spring is mounted, an abutment, formed at the other end of said guide, which one end of said spring engages, a head secured to the other end of said flexible element, which head extends into said guide to engage the end of said spring opposite its abutment-engaging end to compress said spring when urged toward said abutment, and limiting means interposed between said head and said abutment operable to limit the deflection of said spring.
Claim 3
Dependent Claim
52 words
The apparatus of claim 1 wherein said takeup device comprises a rotatable drum on which a portion of said element may be wound, means for rotating said drum to wind a portion of said element thereon, and means for releasably holding said drum to retain a selected portion of said element thereon.
Claim 4
Dependent Claim
93 words
The apparatus of claim 1 wherein said spring is an elongate coil spring, said guide is a tube surrounding said spring, and said flexible element is a cable which extends through the center of said coil spring and outwardly through an end of said tube, and said limit means comprises a second tube shorter than the free length of said spring and extending longitudinally through said spring, with said cable extending through said second tube, said second tube being interposed between said abutment and said head to limit the deflection of said spring.
