Abstract: A washer holding device for temporarily retaining nonmagnetic washers being applied to a building material surface with a fastener gun comprises an arm for affixing the washer holding device to a fastener gun and a washer receptacle joined to the arm. The washer receptacle includes a contacting end, a washer receiving cavity, and a central aperture, with the contacting end defining a distal end of the washer holding device and the cavity sized to receive a nonmagnetic washer such that the washer is temporarily retained within the cavity via a friction fit. An embodiment may include a shoulder, such as an annular flange, recessed from the contacting end, with the shoulder adapted to contact the surface of a deformable building material to limit the depression of the washer receptacle into the building material. The arm may be of various configurations for use with different style fastener guns.
Abstract: A stitching device for producing stitching wire staples for stitching stacked sheet materials, includes a stitching head base body and a cutting box fixed to the stitching head base body. The cutting box includes a movable knife slide. A control device controls the movement sequences of the stitching head, in particular of the knife slide, for cutting off the stitching wire automatically. The stitching head base body, the cutting box and the knife slide are configured in such a way that, during interaction, the movable knife slide can be displaced relative to the stitching base body in order to cut off the stitching wire. The cutting box and the knife slide are provided with at least partly aligned openings in such a way that, during interaction between these openings and an operating device, it is possible to cut the wire off manually.
Abstract: Disclosed is a stapler having various operation modes, as well as methods for switching the stapler among the operation modes. The stapler includes a primary staple magazine, a secondary staple magazine, a staple selector, a drive blade selector and a cover. The primary and secondary magazines respectively contain primary and secondary staples. The staple selector and the drive blade selector are movable for switching the stapler between primary and secondary staple modes. The stapler also includes a perforation for performing a perforating operation, and a switch for securing the stapler in a collapsed, compact form to simplify storage thereof. The stapler is switchable among a primary staple mode, a secondary staple mode, a perforation mode and a storage mode by means of the staple selector and the drive blade selector.

Abstract: A stapler comprises an upper assembly for driving a staple through a stack of papers to be bound, and a lower assembly with a staple anvil for clinching the staples only after the staples are completely driven through the papers. The staple anvil is kept clear of the effort to drive in the staples by a risen table that is allowed to drop around the staple anvil in a second stage of operation. The upper assembly and a handle for the user are provided that are arranged to give the user a 2:1 mechanical advantage with a lever arrangement.
Abstract: A stapler, having a collateral punching function in addition to an original stapling function and being selectively used as a stapler or a punch as desired, is disclosed. In the stapler, a longitudinal base has a staple forming die at its front end portion and two parallel support walls at its rear end portion. A punch hole is formed on the top surface of the base at a position between the two support walls, while a sheet insert slit is formed between the two support walls and the top surface of the base so as to allow sheets of paper to be inserted into the slit during a punching operation. A pressing lever is hinged to the shaft holes of the support walls and its bearing holes using a lever shaft and is manually operated by a user so as to perform a desired stapling operation or a desired punching operation. A staple feeder is hinged to the first shaft holes of the lever.
Abstract: A fastener driving tool for fabricating upholstered furniture and particularly for securing furniture clips, such as a J-type spring clip, to a wood furniture frame. The furniture clips are used to suspend furniture springs across the furniture frame. The tool includes a pivotally mounted magazine which prevents the tool from being operated unless the nosepiece is in engagement with a workpiece. In order to facilitate alignment of the furniture clips with respect to the fasteners, the nosepiece is formed as a guide for aligning the furniture spring clip with respect to the fastener drive track.
Abstract: An improved dimpler attachment for use on gypsum wall board and the like for fastening on a fastener driving tool. The tool housing has a driving piston, pneumatic or other power means to reciprocate the piston and an elongated driver connected to the piston for reciprocation and extending out of the housing. A slide connects a dimpler head to the outside of the housing and bears a fastener magazine. The dimpler head has a central channel slidingly engaging the driver and a pocket adapted to functionally seat a stop plug connected to the driver. The head is connected to the housing by return springs. The front end of the head is curved so that it effects a dimpling action when urged forward on the slide by the forward movement of the plug while seated in the pocket during forward movement of the driver.
