Abstract: A mechanical clamp used to secure hoses includes an elongated band. The band surrounds a central region and has a sequence of slots along its length. An adjustment screw has a hexagonal head that rotates about a longitudinal axis and has a thread that extends into the slots. Rotation of the screw adjusts the area of the central region. The head of the screw allows a driver to transfer torque to the head of the screw at an angle from the axis of rotation. The head is either curved or angled to allow a driver to efficiently engage the head of the screw during rotation when placed at an angle to the axis of rotation.

Abstract: A clip for clamping an article, such as a hose, includes an annular clip band and a plurality of annular insert bands. Each of the insert bands has a first end section and a second end section. The end sections extend in the circumferential direction and overlap one another. One of the insert bands selectively surrounds a radial inside surface of the clip band. Each of the insert bands has a resistance to a relative displacement occurring in the circumferential direction of their mutually overlapping end sections. The resistances for each of the insert bands differs in such a manner that, when a predetermined clamping force is exerted on the clip band in the circumferential direction, a different predetermined radial clamping force on the clamped article results with the use of each respective insert band.

At least one end of the insert is slidable along the strap. The spring or springs ensure that the strap does not become loose as a result of aging of the material of the adjacent portion of the hose.

Abstract: A Quick Release Adjustable Dental Band Clamp is intended to rigidly fix orthodontic attachments to a tooth. There are two major advantages to this invention. First, the band clamp can be compressed to a near-size fit by finger pressure, thereby, reducing operator time with the hand tool. Second, the clamp provides a quick release of tension, enabling fast removal. The clamp is a flexible metal strip with two free ends. One end contains a permanently fixed joining mechanism which is the heart of the invention. The other end is designed to be pulled by a joining mechanism into a created holes interior. The joining mechanism has two main operative parts: a worm and a locking pin. The worm draws the band material tightly and is governed by the locking pin, which is either engaged or disengaged with worm. When the locking pin is engaged with the worm only tightening is permitted. Loosening is allowed when the locking pin is disengaged.
