Abstract: A duct coupling system includes a first duct with a perimeter attached to a compliant sealing gasket and a second duct with a perimeter attached to an annular component sized to interface with a seat of the compliant sealing gasket. The compliant sealing gasket can be selectively tightened around the perimeter of the first duct by engaging a tightening mechanism of a clamp to selectively tension a cable with opposing first and second end portions attached to the clamp and a longitudinal central portion encircling a perimeter of the compliant sealing gasket. Tensioning of the cable causes circumferential compression of the compliant sealing gasket and forms a seal between the first duct and the second duct.

Abstract: Hose clamps fashioned from wire have radially outwardly extending end portions which are connected to overlapping clamping member which is placed in compression when the hose clamp is tightened. In some embodiments the clamping member is a helically wound coil spring which may be integral with the wire or may be a separate element. In other embodiments, the clamping member is a screw-like member. Threads for receiving the screw may be integrally formed in the wire. Various connectins may be provided to attach the free end of the screw to the other end of the tightenable wire. For example, pins and cooperating holes may be for this purpose. If desired, multiple wire members can be serially connected to one another. And, the wire can be doubled on itself with a threaded lug or a hook being formed at the bent end. Coil springs and bights can be used to accommodate dimensional variations in the member being clamped.

Abstract: A lightweight very low-profile hose clamp formed from only three pieces: an elongated wire bent to form a pair of loops which are in spaced side-by-side arrangement and joined at the top by an integral nut section formed by one and one-half tight convolutions of the wire; a heavy gage steel actuating plate having three holes therein, the ends of the wire being bent rearwardly toward the nut section and passing through the end holes of the plate; and an actuating screw threadedly received in the nut section and having a pilot tip received in the central hole of the plate.

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.

Abstract: An improved hose clamp of the kind comprising a tightening band which is bent to annular shape and which has end portions one of which is provided with transverse grooves. In the latter engage the threads of a screw worm which is rotatably journalled in a sleeve enclosing the screw worm but axially non-slidable therein. Said sleeve is formed with a space allowing the threaded band end portion to be moved out of the sleeve upon rotation therein of the screw worm. The opposite band end portion which is attached to the sleeve is elastic in its lengthwise direction and encloses a pressure strap which is bent to annular shape with its end portions overlapping. This pressure strap is arranged to form a guide means to the screw worm sleeve and to the tightening band between said sleeve and said band and an enclosed article. The tightening band describes an arcuate line in the plane of the external face of the pressure strap along the major portion of the circumference of the latter.

Abstract: A wire hose clamp has barbs extending from at least one of the encircling wires forming a part of the hose clamp. The barbs extend in the direction of rotation in which the clamp is urged by the application of a tool to tighten the clamp, and may be inclined to the plane containing the axis of the wire.

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.

Abstract: A pipe restraint device that will prevent pressure-induced separation of cast iron soil pipes or the like joined by a sealing coupling comprises at least one stiff yet forceably springable rod having lengths thereof curved to substantially the outside curvature of the pipe and forming two coils spaced apart for encircling respective pipe surfaces at opposite sides of the sealing coupling, with end portions of the rod or rods arranged in oppositely directed first and second pairs defining a contractable region of the coils; and structures including at least one rigid strut bracket formed to bridge the sealing coupling axially are engaged with the pairs of rod end portions for displacing them relative to one another substantially tangentially under great tension and holding them so displaced in immovably tight engagement upon the pipe surfaces.

Abstract: The invention refers to hose clamps of the U-profiled kind and consisting of steel wire. The hose clamp is double U-profiled and presents both ends U-profiled in order to engage a tension auxiliary spiral spring.

Abstract: A wire grip hose clamp is disclosed, adapted to be applied to a hose by a driving tool having a rotatable socket. The clamp is characterized by having incorporated therein a screw having a relatively long head which is received in said socket, and a base flange formed integrally with said head and of enlarged diameter whereby to provide additional bearing surface for the end of the socket. The base flange has a conical or chamfered surface. These improvements are designed to prevent or minimize any tendency of the socket to become disengaged from the screw during installation of the clamp on the hose. The screw, including the head and flange, are made by forging or cold heading.

Abstract: Disclosed is a clasp assembly for gripping a submarine hydraulic hose or the like which is being suspended by a metal cable. The clasp comprises a tubular clasp body including two matching partial tubular clasp elements which are hinged together along one edge. Lock means which are provided to maintain the two elements together about the hose includes a flange which diverges from each clasp element. A releasable fastener means draws the two flanges toward each other to lock the clasp in its closed position. Each of the clasp elements is equipped with a liner of rubber-like material to provide a firm friction grip on the hose. Clamp means are provided on the exterior of one of the clasp elements for attaching the clasp assembly to a cable or the like used to suspend the hose.
