Abstract: A thin sheet metal strip preferably having a thickness less than 0.015 inch, forms a part-cylindrical portion which integrally connects a folded first ear portion and a second ear portion which is also folded in two embodiments. An integral tongue projects from the first ear portion and may have a pair of parallel longitudinal ribs which project inwardly and interfit with corresponding circumferential ribs formed within said part-cylindrical portion. A sheet metal screw projects through holes within the ear portions, and the second ear portion is adapted to converge toward the first ear portion at a substantial angle relative to the axis of the screw when the screw is tightened for producing a positive non-stripping cocking engagement with the screw. In one embodiment, each of the folded ear portions has a pair of generally triangular side flanges for reinforcing the ear portion, and preferably, the screw engages the tongue to urge it against the hose being clamped.

Abstract: Hose clamps are disclosed comprising a band, band section, or attachment to a band, which yields in a direction circumferentially of the band and which possesses a spring-like quality and/or action such that the clamp is essentially self-adjusting to compensate for thermal expansion and contraction of the assembly (clamp, hose and fitting), as well as for the aging or cold set which the hose undergoes, whereby a fluid-tight seal is maintained throughout the intended life of the assembly, without requiring the clamp to be re-tightened. The bands of the clamps are open-ended and of generally circular configuration and are provided with a tangentially located or oriented worm drive screw for closing the clamp and providing a greater and closer range of adjustment in closing the clamp. The clamps, in some cases, have incorporated therein a positive stop, whereby closure of the clamp can be limited to a specified or predetermined size or diameter.

Abstract: A hose clamp wherein the slotted strap portion is cut to a desired clamp size from a stock supply length. The clamp provides a housing for the two ends of the cut portion. Projections carried by the housing permit a first end of the strap to be removably engaged with the housing. A second member, preferably the second end of the strap, fills the space above the attached first end to interfere with the movement of the first end off the projection. Thus the assembly of a cut strap portion and a drive housing can be accomplished without tools.

Abstract: The housing for the screw of a hose clip has a tubular section with a flat bottom wall a portion of which extends laterally beyond the tubular section and is overlapped by a plate-like second portion forming part of and being inclined with reference to a side wall of the tubular section. When the screw is rotated in a direction to tension the band which is placed around a hose, pipe or a like structure, the screw tends to move the extension toward such structure. The extension is or can be hollow to receive parts of the overlapping end portions of the band. Reinforcing ribs are provided at the outside of the housing between the side wall of the tubular section and the extension. The housing is made of a sheet metal blank which is deformed to form the tubular section and the two portions of the extension, and such portions of the extension are thereupon welded to each other.

Abstract: A hose clamp wherein one end of the clamping band is movable to any desired longitudinal position of the band so as to initially take up the slack of the band during installation of the hose clamp. This same end is held without being permanently attached to the clamping mechanism.

Abstract: A clamp particularly suited for crimp joining the telescoped end portions of thin walled tubing which is prone to inward collapse when overly constricted. The clamp includes an upper and a lower member each of thin metal material and each forming a curved mid-portion the arcuate edge of which contacts the surface of the outer telescoped tube member. Overlying portions at one side of the two clamping members forms a hinging action about the tube. At the opposite side of the members, tubular contours are formed in aligned relationship to one another to receive a bolt and nut fastener. The fastener is operated to draw the upper and lower members together about the exhaust tubes. Prior to operation of the fastener, the configuration of the members is such that a gap is formed between the facing end surfaces of the adjacent tubular portions.

Abstract: The invention is a tube clamp which is used to connect a first pipe to another pipe. The invention can be used, for example, to add a pipe extension to the exhaust pipe used on a car. The tube clamp is made from a plate having a first and second flat portion, each having a hole wherein said holes are equal. The holes are connected by a slot and the plate has first and second flanges surrounding and remote from the hole in the first and second portions of the plate. The plate is transversely bent between the first and second flat portion to a degree to form a connector passage, the plate being bent so that the first and second flat portions are in contact with each other and said holes are substantially coaxial with the first and second flanges directed away from each other. Connector means selected from the group of rivets or welds connects the first and second flat portions. A connector means going through a connector passage connects the pipe flange.

Means for maintaining each of the tension blocks in a defined predetermined position relative to the strap member is provided and includes at least one pin fixedly carried by either the tension block or the strap member and extending through a guideway in the other, and an elastic member such as a spring or elastomer acting on the pin of each tension block against longitudinal movement to predetermine its position relative to the strap member.

Abstract: A coupling or clamp for clamping a tube or a pipe. The coupling is made up of an elongated band surrounding a gasket. Two laterally spaced notches are formed in one end of the band and strikes are fixed to the other end of the band and disposed in the notches. The ends of the band on each side of the notches are bent back on themselves forming eyelets which receive a yoke. The yoke has a curved intermediate part that has a weld nut welded in it and a screw extends through the weld nut. The end of the screw engages the strike. When the screw is swung to a position generally parallel to the diameter of the tube, its end can engage the strike. Then as the screw is swung to a position tangent to the pipe, its toggle action exerts a preliminary tension on the band. Final tension is accomplished by operating the screw in a conventional manner.
