The lugs 10 and 11 are displaced longitudinally and their supports may also be directed outwardly as shown. An additional upstanding lug can be provided opposite the lug 11 to help to prevent undue lateral movement of the end of the strap 2.

Any excessive tightening by the tightening mechanism only causes the stopper to bend towards the cut out by the pressure applied by the overlying end of the band.

Abstract: A helically convoluted hose clamp has a central portion of rectangular cross-sectional outline, two intermediate portions of rectangular or V-shaped cross-sectional outline, and two radially outwardly extending end portions. The moments of resistance of the intermediate portions exceed the moment of resistance of the median portion, and the overall length of the clamp is in excess of 1.5 convolutions preferably between 2.5 and 2.6 convolutions. The inner diameter of the clamp is normally less than the outer diameter of the hose which is to be clamped on a pipe or the like. The length of the intermediate portions exceeds the length of the end portions, and each such intermediate portion can extend along an arc of approximately 360 degrees. Pronounced moments of resistance of the intermediate portions promote the clamping action and prevent the end portions from yielding and bending when they are acted upon to increase the inner diameter of the clamp.

Abstract: The invention contemplates a precisely adjustable threaded mechanism, as for focus adjustment of an aerial camera lens, wherein inner and outer threaded members are normally in circumferentially continuous radially stressed play-free engagement to the extent of requiring a characteristic maximum torque for their rotary adjustment. One of these members is continuously excitable (with respect to the other) as to so incrementally change its circumferential extent with respect to the circumferential extent of the other of said members that their characteristic engagement torque is reduced from said maximum. And a rotary-drive torque of a level less than said maximum engagement torque but greater than the reduced engagement torque is operative to impart an incremental thread-advancing rotary drive, during such intervals as the engagement torque is thus reduced.
