Patent number: 4810952Abstract: A method and apparatus for controlling power delivered to a fastening machine solenoid comprises a half wave rectifier, a filter network, an adjustable frequency generator and a pulse conditioning circuit. The frequency of the frequency generator is varied in accordance with fluctuations in peak AC line voltage and is input to driving circuitry which engages a solenoid at a predetermined time and for a specific amount of time. By increasing or decreasing the solenoids on time in accordance with power line voltage fluctuations, a pulse of constant power will be received by the solenoid, regardless of fluctuations in power line voltage.Type: GrantFiled: June 30, 1986Date of Patent: March 7, 1989Assignee: Swingline Inc.Inventor: Burton E.

Patent number: 4623084Abstract: A hand-held plier type stapler is disclosed. The stapler has a first handle to which an anvil is pivotally mounted. The first handle also houses a stapler head for forming and driving staples. A second handle is rotatably mounted to the first handle. Movement of the second handle moves the anvil towards a workpiece to be stapled and drives the stapler head to form and drive a staple.Type: GrantFiled: January 13, 1986Date of Patent: November 18, 1986Assignee: Swingline Inc.Inventor: Paul Olesen

Patent number: 4598852Abstract: A portable fastener driving tool (10) having a raceway (26) with driver blade (21, 60) reciprocating therein from a retracted position to a fastener-driven position for driving fastener (33, 61) seriatim from a fastenerstick (19, 62) positioned at an angle to the raceway. The first-to-be-driven fastener (33, 61), while attached to the stick (19, 62), is positioned in raceway (26) so that descending blade (21, 60) serves to orient the fastener (33, 61) to a position substantially parallel to the raceway (26) for driving down and out the raceway into the workpiece. Ramp means (37, 46) which form part of tool exit opening (38) re-orients fastener (33) as necessary and guides it during its exit. The fastenerstick (19, 62) may be supported in raceway (26) by detent stud means (29, 31) which retract from the raceway (26) when staple (33, 61) descends.Type: GrantFiled: August 29, 1984Date of Patent: July 8, 1986Assignee: Swingline Inc.Inventor: Paul Olesen

Patent number: 4588121Abstract: 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 reciprocating former member (70) and driver (80). Spring (50) urges base (34) toward sheath (40) with spacer lugs (33) maintaining a defined distant between base (34) and sheath (40).A belt (94) is fed through an opening (100) in base (34) by a cartridge (90) which protrudes into opening (100) and belt advancing means (104, 112) is held inoperative by forming tang (75) during a portion of the forming and driving stroke to prevent movement of staple wire (200) during critical periods of such stroke.The former (70) is moved during the forming and driving stroke through a path which permits former lugs (72) to guide the former staple down to a point adjacent the workpiece (300).Type: GrantFiled: January 14, 1985Date of Patent: May 13, 1986Assignee: Swingline, Inc.Inventor: Paul Olesen

Patent number: 4570841Abstract: 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.
