Abstract: A tool is provided for applying fasteners to a workpiece. The tool as a magazine that carries multiple fasteners and is carried by a housing. A driver blade is provided to drive a lead fastener into a workpiece. The driver blade has a driving edge with a profile that includes driving projections, having curved contact surface for contact with curved edges of the fastener, and a relief portion therebetween that is recessed relative to both projections and contact surfaces. Further, the tool includes a lockout assembly for limiting movement of the driver blade and contact trip, thereby limiting activation of the motor. The pusher may include a pusher lockout surface that is designed for movement in an opposite direction to a feed direction by the contact trip as well as configured to slide over a locking art of the contact trip when the fasteners are empty or nearly empty.

Abstract: A stapler is provided, including: a main body, a striking mechanism and a staple straightening mechanism. The main body includes an inner space and a staple outlet. The striking mechanism is disposed in the inner space and includes a striking member configured to strike a staple and a driving member by which the striking member is driven to move relative to the staple outlet. The staple straightening mechanism is disposed on the main body and includes an aperture corresponding to the staple outlet, at least one abutting member being movable within the aperture and a force accumulating assembly which is drivable by the driving member. The force accumulating assembly includes a blocking portion and a force accumulating member which is releasably blockable with the blocking portion, and the force accumulating member is movable toward the aperture to strike the at least one abutting member.

Abstract: An electric stapler (10) is disclosed as including a stapling head (12) with a driver (28), an intermediate magazine (14) for carrying staples each with two legs, a base part (16) carrying two anvils (44), cams (24), and eccentrically mounted wheels (52), in which the stapling head (12), intermediate magazine (14) and base part (16) are movable relative to one another, the eccentrically mounted wheels (52) are rotatable to move the stapling head (12) and intermediate magazine (14) relative to each other and relative to the base part (16) whereby the driver (28) of the stapling head (12) drives a staple away from the magazine (14), and the cams (24) are rotatable to move a movement transmission assembly (30) to move the anvils (44) to bend the legs of the staple.

Abstract: Clincher holders hold a pair of clinchers for bending the legs of a staple driven by a driver, and have slanting guide faces for guiding the tips of the legs of the staple toward the clinchers. In a stapling table for receiving sheets of paper, an opening is made. The clincher holders are movable inside the opening. Drop-preventing portions for preventing the sheets of paper from dropping inside the opening in stapling are projected from opening edges of the opening toward the inside of the opening.

Abstract: Placing unit and method for placing locking ring bolts. The placing unit includes a gripping jaw housing in which at least two gripping jaws are arranged, a housing that surrounds the gripping jaw housing, a tip with an opening is arranged on a front face of the housing, and an opening element that limits an axial movement of the gripping jaws in one direction, while allowing the gripping jaw housing to move further in the one direction. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A stapler anvil and method for clinching a staple is disclosed. The anvil includes a body having a well. The well has an axis extending between the legs of a staple and is defined by a first surface having a first portion along which the first leg of the staple is directed as the staple is being clinched, and a second portion extending substantially at an angle relative to the first portion to direct the second leg of the staple at least partially away from the axis as the staple is clinched. The well is further defined by a second surface spaced from the first surface. The second surface is configured to redirect the second leg of the staple at least partially back toward the axis after the second leg has been directed at least partially away from the axis by the second portion of the first surface.

Abstract: Problems: To provide a stapler apparatus that clamping of the sheet bundle is smoothly shifted to staple driving operation for stapling at correct position irrespective of thickness of the sheet bundle.

Abstract: When connecting two elements that are moveable with respect to one another, someamount of clearance, i.e., spacing between the elements, is included to minimize friction between the elements. The present invention is directed to setting the clearance within a desired range, regardless of manufacturing tolerances of the two elements. In particular, the present invention is directed to power cutting tools wherein it is necessary to set the clearance between one or more reciprocating blades and a blade support member.

Abstract: The machine according to the invention comprises a device for feeding at least a continuous belt from a coil, a punching unit provided with at least a punch for punching holes into the belt; a cutter for cutting the continuous belt in segments of the desired length and a unit for applying and shaping the hooks to the belt. The unit includes a feeder for feeding and positioning the locking bushings relative to the belt holes, an inserter for inserting the hooks into the holes provided in the locking bushings and into the holes punched in the belt and a closer for closing the locking bushing about one hook end and for simultaneously shaping the other hook end.

Abstract: The method of assembling lead-mounted electric components such as DIP 18 in automated fashion to a printed circuit board 14 is accomplished by building up a crimping tool (FIG. 7) comprising a base 28 with crimping anvils 12, 20, 22, 24, by selectively positioning and orienting the anvils on the base while the base is energized to provide a moderately low strength field, and the base is then energized to provide an adequately high strength magnetic field to retain the anvils properly during the subsequent steps of mounting the components to the board and crimping the leads to produce a particular type of board. After the requisite number of boards of a particular type are built, the anvils are removed to storage and the base is rebuilt to provide a different array of anvils for a different board.

Abstract: A surgical fastener of plastic or plastic-like material includes initially separate fastener and retainer members. The fastener member has at least two parallel prongs, each of which fits into a respective one of at least two apertures in the retainer member. The prongs twist as they enter the apertures. Then the prongs return to their initial orientation in which they interlock with the retainer member to form a finished fastener. The fastener is applied by forcing the fastener member prongs through the tissue to be fastened with the aid of metal pins contiguous with each prong. The pins are automatically withdrawn from the tissue after the prongs interlock with the retainer member and before the fastened tissue is removed from the fastener applying apparatus.

Abstract: A fastener for cloth and similar materials is secured thereto by means of apparatus which includes an elongated member which is tempered in the form of a coil. Absent restraint the coil will move in a direction which is tangential to the envelope of the coil and carry therewith portions of the fastener and in cooperation with a base and a punch the members of the fastener are assembled.
