Abstract
A radially-adjustable wire grip hose clamp made of a single wire strand forming a pair of coaxial, axially-spaced clamping loops. Each loop having a portion progressively traversing a seat element as said clamp is adjusted by a radially-disposed screw threadedly engaging a nut and bearing upon the seat element. The traversing portions are maintained at equal length to stabilize the screw against tipping and a mechanical interlock configuration of bends retains the nut against torsion-induced angular displacement.
Claims13
An adjustable wire grip hose clamp, comprising:
- a wire body providing a pair of circular clamping loops in axially-spaced relationship to each other, a common seat element having means at each end for receiving therethrough a first portion of each of said loops for attachment of said seat element to said loops and for maintaining said loops in said axially-spaced relationship, each of said loops having a deformed first portion thereof traversing said seat element,
- said first portion being sequentially deformable by said seat element in response to constricting movement of said loop, a threaded nut proximate to and radially spaced from said seat element,
- said first portion extending from said seat element to said nut, a second portion of said wire body extending from said first portion and bent into securement with said nut, and a radially-extending adjusting screw threadedly engaging and traversing said nut and seating on said seat element, whereby screw-induced elevation of said nut relatively to said seat element progressively tensions said loops simultaneously to create sequential re-formation of said deformed first portions relatively to said seat element and constriction of said loops into clamping engagement with a hose embraced thereby.
