The external threading of the half cylinder is capable of mating with the internal threading of the bore whereby the half cylinder portion and the flat longitudinal surface portion inserts and screws into one end of the bar, wherein the flat longitudinal surface portion is positioned as to allow at least one bolt to be inserted through the bar holes perpendicular to the bore along the flat longitudinal surface portion.

Abstract: An improved machine screw for engaging a correspondingly threaded aperture, comprising a threaded shank having a proximal portion and a distal portion. A head adapted to be rotated may be formed on a shank proximal end opposite the shank distal portion, such that the shank extends axially therefrom. The shank is deformable from a first position to a second position, for either (1) minimizing the contacting surface area between the shank and said aperture, and thereby allowing the machine screw to be easily insertable into said aperture, or (2) maximizing the contacting surface area between the shank and said aperture after the shank has been fully inserted into said aperture, and thereby making the hold between the screw and said aperture more secure. Such deformation of the screw occurs during its insertion into said aperture. It has been found that this deformation prevents screws of the present invention from seating improperly within threads of said aperture.

Abstract: The present invention discloses a self-tapping anchor and a method of installing the anchor into a wall. The anchor includes a flange portion, a drill end portion, and an intermediate shank portion. The intermediate shank portion has a central bore therein for receiving a fastener. An external thread is formed on the shank portion for threading the anchor into the wall. The shank portion is divided by a slot into a pair of leg portions and the external thread is divided into a plurality of discrete thread segments. The drill end portion supports the leg portions to prevent relative twisting therebetween during anchor installation into a wall. A reduced thickness web portion, or alternatively, a through slot, is formed in the drill end portion. When the threaded fastener is threaded into the central bore, the fastener causes the drill end portion to split apart releasing the leg portions so that the leg portions diverge to provide better anchor securement to the wall.

The assembly includes a cap that is attachable to the bottle, the cap including an annular collar spaced from the cap by a pair of integrally moulded legs. A separate eyebolt member has an annular eyebolt portion and a shaft portion extending radially therefrom, the shaft portion being receivable in the collar of the cap. A separate securing member is provided to prevent unwanted disconnection of the eyebolt member from the cap. The eyebolt member can rotate or swivel relative to the cap and a rope or chain can be connected at one end to the eyebolt portion and at the other end to a net or other underwater structure. Bottles that would otherwise be destined for the garbage pile or landfill site can be utilized with the invention to provide inexpensive, easily replaced, floats or buoys for any number of marine applications.

Abstract: Disclosed is a quick fastening quick releasing nut-and-bolt assembly in which the bolt has finger elements disposed along the bolt's longitudinal axis. The finger elements have sets of accurate thread segments matable with complimentary sets of radially inward facing arcuate thread segments on the inner diameter of a nut. The nut's inner diameter includes smooth semi-cylindrical surfaces circumferentially alternated with the nut's sets of thread segments. The nut has a central core body sliding upon radially inner surfaces of the finger elements so as to keep the finger elements in bearing relation with the nut's inner diameter. The assembly has a first, unlocked configuration in which the bolt's thread segments face the smooth surfaces on the nut's inner diameter. The assembly has a second, fastening configuration where the bolt's thread segments are engaged with the nut's thread segments.

Abstract: A fastener system is providing having a male threaded member and a female threaded member with arrangements for achieving a locking connection between the parts to prevent relative rotation of the parts due to vibration. In an embodiment of the invention, the male member is comprised of a folded over plate with threads formed on an end portion, either the folded end or the free ends, or both, which is engageable into the female member. In another embodiment, the male member is formed of two pieces overlying one another with threads formed on the overlying portions. The thickness, width and number of threads on the male member can be selectively determined to provide the desired torque for rotating the two members relative to one another. The male member can be configured as a linear member, an offset member, as a clevis, or other non linear shapes, which shapes are particularly easy to accomplish by forming the male member of two legs either by folding or as separate pieces.

Abstract: The present invention relates to a compressible screw-type locking mechanism including an oversized locking screw and a tool for compressing and rotatively driving the oversized locking screw through a threaded bore. Formed about the top of the locking screw is a head portion and extending downwardly from the head portion is a threaded shaft. At least one longitudinal slot extends through the head and at least partially through the shaft to form a locking screw with plural resilient segments. The locking screw assumes a normal expanded state with its threaded pitch diameter being oversized with respect to its companion bore. The locking screw is compressed by engaging the head thereof with the tool. In one embodiment, the compression of the locking screw is achieved through a torquing action. In a second embodiment, the compression is achieved by the axial movement of the tool.
