The stapler is acted upon by a drive system which is movable in the working direction of the compression springs. The compression springs are associated with the base member, the driver, and the sleeve, and arranged in preloaded fashion thereon, in such a way that upon actuation of the stapler, a force-controlled drive occurs in an operationally correct sequence.

Abstract: Picture hangers having prongs become automatically inserted into a picture backing material. An insertion apparatus feeds a strip of preformed blanks to an anvil which severs the blanks and presses them into the backing material. At the same time that the apparatus severs the first blank of the strip, a prong forming tool, attached to the anvil, bends the prongs of the next blank. A feed rod advances the strip of blanks through the apparatus, one blank at a time. A pair of paws, attached to the anvil, carry the severed hanger to the picture backing, and releases the hanger as the hanger becomes inserted into the backing. The apparatus includes a resilient structure which enables the device to operate efficiently with picture backings having varying thicknesses. One can also use the invention to insert hangers into picture frames, mirrors, plaques, signs, or the like.

Abstract: The hemostatic clip applicator system is particularly useful for endoscopic procedures. A hemostatic clip applicator can be directly connected to a trigger assembly or indirectly connected to the trigger assembly through the use of an extension. The connection between the extension and the clip applicator is secured to prevent accidental release during the procedure. The applicator receives a longitudinal input and translates the input into relative component motion through the use of gearing to apply the clips.

Abstract: A rotatable wire holder for a stitching machine head has a wire-receiving slot between two wire support surfaces, and wire cam surfaces which guide the wire from the slot to the support surfaces in response to rotation of the holder. Permanent magnets hold the wire on the support surfaces. The holder is used in a stitching machine head including feed mechanism for gripping and feeding a length of wire from a continuous coil supply to the holder, a cutter for severing the length of wire from the supply and a former/driver movable past the holder for forming the held length of wire into a staple and driving the formed staple into an associated workpiece.

Abstract: A staple forming and driving apparatus utilizes bulk wire as the starting material. The apparatus has a fixed anvil block and movable forming and driving blocks. The anvil block contains an anvil about which a staple is formed and a stripper member which is normally biased to the extended position covering the anvil block. A forming block has a pair of projecting camming surfaces which, when it approaches the anvil block, causes the stripper member to recede. After the stripper has been cammed back, wire enters the anvil block across the anvil unit until it contacts the opposite side. The forming block continues to advance until a centrally disposed pressure foot contacts the wire holding the wire in place against the anvil. A forming blade on either side of the pressure foot continues to advance, cutting the wire and bending it around the anvil to form a staple.

Abstract: A wire piece forming device includes a wire piece dispenser with a cutting mechanism, a receiver member which receives wire pieces from the dispenser and a take-over member. The wire piece dispenser includes a feed device for the stepwise feeding of the wire. The device includes feed wheels which are driven intermittently by a four-bar linkage and a freewheel. A wire guide member is provided to ensure that the beginning of the wire is reliably inserted into a groove-like recess in a receiver member. The groove-like recess is open at its bottom. Before a wire piece is cut off by a cutter, the groove-like recess is closed by a take-over member moving past the opening of the recess. The take-over member then takes the separated wire piece and carries it away.

Abstract: Electrical components are processed faster and more reliably with an improved centering device.
