Abstract: A pipe coupling device for coupling the peripheral flanges of a pair of pipes together, including a pair of retainers with a V-shaped groove therein for receiving portions of the peripheral flanges of the pipes. The retainers are pivotally coupled at one of their ends by a hinge assembly and releasably coupled at their opposite ends by a latch mechanism. The hinge assembly has at least two links pivotally coupled at one of their ends to one of the retainers by a first pivot pin and pivotally coupled at their other ends to the other retainer by a second pivot pin. The pivot pins are separated from each other such that the links of the hinge assembly straddle the peripheral flanges of the pipes. This arrangement provides more uniform pressure at the ends of the retainers since the moment resulting from the offset of the hinge assembly is moved closer to the circumferential loading line between the retainers and the flanges of the pipe.

Abstract: A locking clamp assembly includes a circular band of flexible material having, first and second end portions and a series of indentations formed in the outer surface of the band along the length of the band at the first end portion.

A screw is also disposed within the channel and has a threaded portion with a plurality threads which threadably engage the indentations of the first end portion of the band so that when the screw is turned, the band is tightened and loosened. A locking device releasably locks the screw to the housing its desired position wherein the screw is prohibited from turning thereby preventing the tightening or loosening of the band.

A first end of said blade is axially fixed to the housing and provided with an opening in which the tail of the screw may slide, whilst the second end of the blade surrounds at least partially the shank of the screw in the vicinity of its head and is mounted to slide with respect to the sides of the housing.

Abstract: A clamp for tightening a strip of arbitrary length around an object. The clamp includes tightening mechanisms which attach to the ends of the strip. The mechanisms are adapted so that the inner surface of a cup-shaped element of one mechanism receives the free threaded end of a tightening bolt which is pivotably mounted in a rotatable cross-peg extending through ears of the other tightening mechanism. One end of the strip is selectively securable to the clamping mechanism by a locking device having an aperture and bendable ears. The strip is locked by being passed through the aperture, folded back on itself, folded forward on itself, held by bendable ears crimped over the folded strip, and again folded back on itself and held by a second set of bendable ears crimped over the folded strip. The clamp is particularly useful for tightening a hose around an object without forming a bulge in the hose thereby preventing local leakage.

Two partly circular plate members are laid against the edge portions with through-going partial longitudinal holes being provided in the circular plate members and the edge portions. A screw bolt is then able to be passed through the longitudinal holes with nuts secured onto said screw bolt for pressing the circular plate members toward one another for tightening the circular sleeve-like structure around the respective conduit.

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.

Abstract: A pipe coupling comprising a sealing gasket to fit over adjacent ends of pipes to be connected end-to-end and a housing which clamps around the gasket, has the housing in the form of a cast metal or alloy band which substantially encircles the gasket and has at its circumferential ends opposed lugs between which a wedge portion of the gasket extends and which are connected by at least one clamping bolt engaged with retaining means, whereby the lugs can be urged towards one another to contract the band onto the gasket. The lugs grip the wedge portion as the band is contracted and prevent the body of the gasket from bulging outwardly between the lugs. Preferably the band is made of a ductile metal or alloy, e.g. ductile iron, and is slightly oval in its free state so that it assumes a substantially true circular form when fully contracted onto the gasket.

Abstract: A clamp to retain a hose on a conduit for reproducibly controlling the closure of the clamp to obtain a consistent diameter for the clamp. A spacer is removably carried by a screw on the clamp and is disposed between a nut means and a projecting portion of the loop of the clamp. Turning the screw in a closing direction reduces the diameter of the clamp by moving the projecting portion towards the nut means. The removable spacer limits movement and reproducibly defines the diameter, and hence the closure of the clamp. The removable spacer engages the body of the screw with a snap fit for easy installation and removal. The spacer further has a tab on a frontward face to prevent rotation of the spacer and to facilitate removal. The spacer further has a depression on a rearward face in which an instrument may be inserted to assist in removal of the spacer.
