Abstract
A self tightening hose clamp is disclosed, having a band for encircling at least a portion of circumference of a hose and a bolt which extends from a left end of the band through the right end of the band and about the remaining portion of the circumference of the hose. A spring circumscribes an outer end of the bolt and applies a biasing force on the bolt and the right end of the band to maintain a clamping force between the band and the hose during contraction of the hose. A sleeve is disposed between the bolt and spring to coaxially center the spring about the bolt during compression.

A hose clamp for clamping a hose about a nipple, the clamp comprising:
- band means for encircling at least a portion of the circumference of the hose, said band means having a first end and an opposing second end;
- bolt means extending over the remaining portion of the circumference of the hose, said bolt means having a T end movably attached to said first end of said band means and an opposite rod end portion including a first end of said bolt means;
- spring means circumscribing said rod end portion, said spring means having one end operatively contacting said second end of said band means and an other end operatively contacting said bolt means, for biasing said second end of said band means in a direction generally away from said first end of said bolt means;
- and
- sleeve means disposed between said bolt means and said spring means for coaxially centering said spring means about said rod end portion of said bolt means during compression of said spring.
