Abstract: A staple forming and driving tool (10) employing a vertical front portion of a staple head base (34), and sheath (40) to provide a space for the reciprocating former member (70) and a driver (80). A spring (50) urges base (34) and the sheath (40) together with spacer lugs (33) maintaining a defined distance between the base (34) and the sheath (40). A belt of staple blanks is fed through an opening (100) in the base (34) by a cartridge. The cartridge extends into the opening (100). A belt advancing means (104, 112) is provided which is held in an inoperative position by the forming tang (75) during a portion of the forming and driving stroke in order to prevent movement of a staple wire (200) during critical portions of the forming and driving stroke. The former (70) is moved during the forming and driving stroke through a path which permits former lugs (72) to guide the formed staple down to a point adjacent the workpiece.

Abstract: A staple forming and driving tool for forming staple wires fed from a staple belt into staples and driving such staples into a workpiece comprising a driver, a former positioned to be driven by the driver, a former block and a sheath, all of which parts are held to a stationary stapler head by means of a single spring. The driver blade, former, sheath and stapler head have generally planar portions positioned in parallel planes and are held in contact with one another by the spring. In the event of jamming, the spring may give permitting the sheath to move away from the fixed stapler head, thus providing space for ejection of one or more jammed staples or staple blanks. Upon correction of the jamming, the parts promptly reassume their proper position under the urging of the spring and the device is ready for operation once again.

Abstract: A burster for separating successive sheets of paper from a continuous web of paper has at least one output or draw roller having a larger diameter than the input or feed rollers with all of these rollers rotated at the same r.p.m. and a simple belt drive mounted on a pivotal double link with a one-to-one ratio provides for driving one set of rollers from the other set with an adjustable distance between sets of rollers.

Abstract: The present disclosure relates to a corrugated fastener for joining two pieces of material in abutting relationship, the fastener having two spaced-apart corrugated loop sections and an intermediate curved tensionable section having a shape and size such that as the fastener is driven the curved tensionable section is substantially straightened and held under tension to draw the two pieces of material together. The disclosure also relates to an adhered strip of a plurality of such fasteners resembling a modified honeycomb configuration. The manner of collation of the adhered strip enhances the functional features of the disclosed fasteners.

Abstract: A magazine having an upper fastener holding chamber including a floor, a lower housing and a magazine cover that can be adjusted to a number of heights above the chamber floor without such cover being removed or the interconnectors used to secure the cover to the housing being disassembled. Alignment positioning of the magazine cover at a selected height above the floor is accomplished by locating pins and complementary holes.

Abstract: An electronically operated portable fastener driving tool is disclosed. Fasteners are driven into a workpiece by a driver blade which is actuated by a solenoid powered by a source of alternating current. Each actuation of the device produces a predetermined plurality of driving strokes being delivered to a fastener. The tool is also provided with means for preventing more than one fastener from being driven during each actuation of the tool.

Abstract: A device for simultaneously stapling and marking a workpiece is disclosed. The device comprises a main body housing means for driving staples into a workpiece as well as means for supporting a removable marking unit. The marking unit is positioned in the housing in such a manner as to apply an identifying mark to the workpiece when the workpiece is stapled.

Abstract: A carrier for holding sheets of material to be bound along one edge thereof for use in a thermal binding machine. The carrier includes two side portions and a bottom portion which cooperate to support glue material to maintain the edges of the sheets being bound proximate the glue material. The bottom portion defines an inner surface which allows the bound material to be withdrawn from the bottom portion while maintaining the material in a bound disposition.

Abstract: A binding system is disclosed for binding volumes comprising a cabinet having a trough herein for the receipt of an edge of a stack of sheets with power compressor means on one side of the trough for compressing the stack of sheets and power operated stapling means on the opposite side of the trough for driving staples through the major plane of said sheets adjacent said one edge while under compression. The cabinet also includes a second power operated stapler for binding smaller or thinner stacks of sheets to produce thinner volumes. An interlock provides that only one of the two power operated staplers may be used at a time. Provision is made for loading the larger of said power staplers through the top of the cabinet and a safety mechanism is provided to insure against ejection of staples from the magazine upward through the loading entryway.

Abstract: A collapsible rack is disclosed which comprises a plurality of partition members which are pivotally joined together at their bases with linking members to form an expandable lazy tong structure. A plurality of guide means which are each secured to and integral with the linking members are provided for guiding stacks of sheets placed in the rack. The guide means define slanted guide surfaces which extend between the bases of adjacent partition members. The guide surfaces all have a substantially common orientation on the linking members. The guide means also serve the function of improving the rigidity of the structure, defining back-up surfaces that insure the proper support of the sheets and fan the sheets into oblique relationship with each other enabling convenient removal of the sheets.

Abstract: An electrically operated stapling device is disclosed. Staples are driven into the article to be stapled by a simple driver blade which is powered by a current actuated solenoid. In the preferred embodiment, the solenoid is provided with a plurality of pulses which are derived from alternate half-cycles of an AC power source which powers the stapling device. The circuit produces two pulses by defining a window in each of the successive output cycles of the power source. The current then initiates the generation of an enabling signal which lasts for a predetermined period of time which begins during the window. During this period of time, alternate half-cycles of the power source are coupled to the solenoid, thereby causing the driver blade to drive the staple into the article to be stapled.
