Patent number: 4542844Abstract: 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.Type: GrantFiled: October 4, 1982Date of Patent: September 24, 1985Assignee: Swingline, Inc.Inventors: Paul Olesen, Albert Lensky, Richard J.
