摘要： A series of drywall screws are nested together and individually seated with a special driving tool after separation from one another. Each screw is hollow and has interior and exterior screw threads. One end of the screw has a hollow flat head and the body tapers downwardly to a bottom portion having a diameter less than half the diameter of the first end. A drill bit having an eccentric point drills a bore having a diameter greater than the diameter of the drill bit so that the bore operatively receives the screw.

摘要： A horizontally extending reinforcing bar having a central core in transverse cross-section exhibiting at least three radial fins projecting outwardly symmetrically from the center of the bar to its outer edge. Each pair of adjacent fins define a valley between them containing a pattern of raised surface area. Two in-line reinforcing bars are held together by a coupling device having a housing with multiple flexible inwardly projecting plates from grooves in an inner wall. The plates flex in the direction of insertion of a reinforcing bar and exert a force to prevent removal of the bar.

摘要： A plurality of fasteners each having an enlarged head with a slot or a passageway there through to accommodate and cage the shank of another like fastener so that the plurality of fasteners form a self-contained collated strip. Preferably the fastener has at least three spaced vertical cups and edges about a central core with a pair of adjacent edges of one fastener caged in the complimentary slot of the adjacent-like fastener. A notch is provided on such pair of edges to releasably lock the fasteners together in the strip.

摘要： Apparatus includes a mandible alignment device and a jaw pattern jig to prepare a one-piece metal dental implant for insertion into a patient's mouth. The alignment device has a central scissors member with a rear positioned thumb wheel controlling the longitudinal spread of the scissors blades. A front portion of a longitudinal angle adjustment member mounted over the scissors holds an anterior foot portion of a dental implant. A rod integral with the end of each scissors blade supports a housing holding a ramus member portion of a dental implant. After a pattern is determined by the alignment device, it is locked into the jaw pattern jig and the one-piece metal dental implant is bent to shape to substitute for the anterior foot and ramus members removed from the alignment device.

摘要： A fastener feed assembly for a tool such as a power screwdriver having a drive member such as a rotatable bit includes a base fixed to the tool and a nose assembly slidably related to the base. The nose assembly includes a workpiece engaging surface, and when the tool is moved toward the workpiece during a fastener driving operation, the base moves toward the nose assembly. A return spring separates the base and nose assembly when the tool is withdrawn away from the workpiece. A strip of fasteners is fed from a magazine along a feed path through the nose assembly with sequential fasteners located in a drive position. Normally the drive member is spaced from a fastener in the drive position. During movement of the tool toward the workpiece in a driving operation, the drive member moves into engagement with a fastener in the drive position, and then continues to move in order to drive the fastener into the workpiece. A pawl is engageable with the strip in order to advance the strip along the feed path. During the driving operation, a feed mechanism operates in response to movement of the base toward the nose assembly to cock the pawl by moving it away from its home position along the strip away from the drive position. A lost motion arrangement delays cocking of the pawl until after secure engagement of the drive member with a fastener in the drive position. In response to withdrawal of the tool from the workpiece, the feed mechanism returns the pawl to its home position to feed an adjacent fastener of the strip to the drive position. Feed movement of the pawl is delayed until withdrawal of the drive member from the strip feed path. The strip includes a carrier with structure deformed during the drive operation for preventing reverse movement of the strip during cocking of the pawl.

摘要： A machine for making concrete reinforcing bars, known as rebars, from wire stock having a round cross section. A preform roller station cold works the round cross section of the wire stock into the shape of a polygon. A first form roller station cold works the polygonal cross section into a cross section having a central core and radial fin members extending therefrom. A second form roller station further reduces the diameter of the central core, and further increases the radial extent of the fin members. A third form roller station reduces the core still further, and again increases the radial extent of the fins, imparts shoulder members that provide an anti-longitudinal slip function at preselected intervals along the extent of the rebar, and roughens the rebar.

摘要： A wire straightener and multiple preform rollers prepare a continuous length wire for further forming by multiple form rollers having multiple spaced apart notches formed in an annular edge of the rollers. Some notches skip a section of the wire to be headed, and other notches serve to form barbs in the wire. In a first embodiment, after the formed wire is fed to a gripper housing where the wire is cut to a predetermined length, the skipped section is punched to create the fastener head. In a second embodiment, the formed wire is cut and fed to a rotary heading machine.
