Screw Locked Band Clamp Patents (Class 24/20LS)
  • Patent number: 6035495
    Abstract: A hose clamp having a self-threading hardened screw extending through outwardly extending tabs on the generally circular clamp, the head end of the screw fitting through a clearance opening in the first tab, and the screw threadably engaged with the second tab, the first tab being reinforced against bending by a deformation dimple at the juncture to the circular band, and the second tab being bendable upon screw tightening to cause the screw angle to change sufficiently for the screw threads to cut slots in the band, forming a worm-type drive engagement.

  • Patent number: 5309607
    Abstract: A hose clip which comprises a flexible strap adapted to be placed around a selected portion of a hose and to be tightened around such selected portion by turning a bolt or screw. An elongated concavo-convex strip-shaped resilient insert is adjacent a portion of the internal surface and extends in the circumferential direction of the strap opposite the mechanism which serves to increase or reduce the effective length of the strap. The convex external surface of the insert is biased in a direction away from the adjacent portion of the internal surface of the strap by one or more springs which are disposed between the insert and the strap and are of one piece with the insert. 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.

  • Patent number: 5220710
    Abstract: A clamping assembly constructed to hold an electrical cable or tube in a fixed position includes retaining and clamping members. A first surface of the retaining member, which may be made from a compliant material, has raised and lowered portions in a particular pattern. One end of the retaining member has a face transverse to the first surface of the retaining member with raised and recessed portions defining a mating relationship with the raised and recessed portions on the first surface of the retaining member. The clamping member may be made from a springlike material and may be disposed in an open loop in an unconstrained relationship. The clamping member may be disposed in a longitudinal slot in the retaining member so as to be encased by the retaining member. The retaining member may be slitted to communicate with the slot for facilitating the disposition of the clamping member in such slot.

  • Patent number: 5138747
    Abstract: An auxiliary spring structure for use with open clamps in which the auxiliary spring member is contained within a cage formed by the outer band portion whereby the free leg portions of the auxiliary spring member extend through slot-like openings in the cage to engage the latter from the outside so as to resist elastically forces seeking to enlarge the circumferential dimensions of the clamp. In another embodiment, the auxiliary spring structure is formed by one or preferably several interengaged leaf springs which are connected between the end area of the outer band portion and the clamping band near the beginning of the inner band portion. Any gaps resulting in the auxiliary spring structure are thereby covered by the full band width of the inner band portion. The auxiliary spring structure of this invention can be used with one-ear clamps, earless clamps and screw-type clamps.

  • Patent number: 4672515
    Abstract: The present invention consists of a device that provides for easy adjustment of the direction of illumination produced by a utility light through a multiplicity of orientations from one attachment position. The device herein uses a metal track attached to the utility light, which track passes through a clamp and wherein the clamp can be releasably attached to various points along the track. Thus, by movement of the clamp along the track, the direction of illumination produced by the utility light can be adjusted. In addition, the device herein includes a magnet connected to the clamp for mounting of the utility light on suitable ferrous-metal support objects. Engagement and disengagement of the clamp from the track is accomplished by rotating the magnet.

    Abstract: A lockable band clamp, such as clamping together the rims of a housing and a base of an equipment housing, has a flexible band with Vee-shaped portions for positioning around the rims, the rims positioned in the Vee-shaped portions. The ends of the band have end members through which passes a bolt, a tubular member threading on to the bolt. Relative rotation between bolt and tubular member acts to pull the end members together and tighten the band about the rims. The end members have projections which overlap. A locking member which, in a locked position, engages at one end over a rod through the tubular member and at the other end aligns with holes in the projections whereby a padlock can pass through the holes and a formation on the locking member, preventing relative rotation between bolt and tubular member.

  • Patent number: 4446605
    Abstract: A clamp has a split ring with projections extending outwardly from shoulders on the ring. The projections converge towards each other outwardly of the ring and have grooves onto which a nut is threaded. This causes the projections to be moved towards each other thereby closing the gap in the ring, and tightening the clamp. The inward movement of the projections is facilitated by grooves in the shoulders. A rib and projections are provided on the radially inner surface of the ring to facilitate the gripping of a body clamped by the clamp. A strengthening rib and handles are provided on the radially outer surface of the ring. The clamp is simple and secure and can be manufactured cheaply from a plastics material.

  • Patent number: 4310956
    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.
