Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
167 words
In a self-tightening encircling clamp, the combination of a body portion forming a closed loop of relatively stiff spring-like resilient wire, said wire loop being flattened to bring its two opposite sides into a parallel spaced relationship, said sides being rolled into a circle of substantially less diameter than the outside diameter of the smallest hose upon which the clamp is to be used, a first extremity of said loop configuration being bent to form a U-shaped loop and the second extremity being bent to form a U-shaped profile; a screw-shaped adjusting means to increase or decrease the size of said loop structure, said screw presenting a tapered terminal portion, an intermediary nipple presenting on its front side a blind hole and formed to receive on the side opposite said front side a centering finger; said screw being screwed to said first nipple and cooperating with said tapered terminal portion and with said intermediary nipple; and a spring mounted between said second extremity and said intermediary nipple.
