Definitions

  • This invention relates to portable fastener driving tools which drive fasteners seriatim using a reciprocating blade and include a magazine housing lower surface which is held against the workpiece during operation and, in particular, to a portable fastener driving tool having a fastenerstick magazine lower surface positioned at an acute angle to the plane of movement of the reciprocating blade to permit the tool to be positioned for driving in heretofore inacccessible corners or other areas.
  • U.S. Patent Specification No. 2,086,922 to Peterson teaches use of a staplestick magazine positioned generally parallel to the driver blade with an arrangement of reciprocating parts to remove seriatim staples from the staplestick and thereafter transport and orient them for driving.
  • U.S. Patent Specification No. 2,396,356 to Wick- ens meters individual staples down a rail at an acute angle to the drive blade.
  • a portable fastener driving tool in which fasteners are driven along a fastener driving raceway by a reciprocating driver blade out an exit opening into a workpiece and in which each fastener is fed from a reloadable magazine into raceway at an angle to the raceway, comprising
  • a portable driving tool in which staples each having a crown and two legs are driven along a staple driving raceway by a reciprocating staple driver blade out an exit opening into a workpiece and in which each staple is fed into the raceway for driving with its legs at an angle to the raceway, characterized by
  • the invention comprises a portable fastener driving tool having a reciprocating driver blade and a fastener magazine in which the fastenerstick is positioned at an acute angle to the plane in which the driver blade reciprocates.
  • One end of the fastenerstick abuts the fastener raceway with the first-to-be-driven fastener positioned at an acute angle to the driver blade.
  • the first-to-be-driven fastener is sheared from the fastenerstick by the force of the driver blade.
  • inclined fastener ramps adjacent the exit opening of the tool urge the fastener back into the raceway, if it is has moved out of the raceway, to assure proper alignment of the fastener as the fastener exits the tool.
  • Fastener ramps, together with the raceway define an exit opening which guides the full length of the fastener as it moves through the opening into the workpiece.
  • a retractable stud which may be termed a "detent”
  • a detent is positioned in the raceway which detent serves to assist in orienting the first-to-be-driven fastener as the blade strikes and moves such fastener during the driving stroke and also serves to support the fastenerstick during loading of the magazine.
  • electrically powered staple driving tool 10 includes housing 11, trigger 12, electrical power conduit 13, staple magazine 14.
  • Latch 16 permits access to magazine for loading and unloading staplesticks.
  • Below housing 10 is a lower drive frame 17 which carries front sheath 18.
  • driver blade 21 and a staplestick 19 riding on rail 24 being urged toward and against staple raceway 26 by magazine spring means 25 (in dashed lines in Fig. 1).
  • Rail 24 has a sloping front which parallels raceway 26.
  • Tool 10 is shown positioned in a 90° corner formed by a floor 22 and a vertical wall 23. The configuration of housing 10 and the angle of the magazine 14 to driver blade 21 permits driving staples in the corner.
  • Driver blade 21 reciprocates in staple raceway 26 formed in front sheath 18 using an electric solenoid and suitable blade return mechanism such as spring means (not shown).
  • the front face 27 of sheath 18 has an aperture in it for receiving detent stud 29.
  • Detent stud 29 is positioned in staple raceway 26 adjacent the first-to-be-driven staple 33 of staplestick 19. Stud 19 may be positioned below and tangent to the crown 39 of the staple 33, as shown in the drawings, or may be positioned in a slightly lower position.
  • inclined ramps 37 are positioned adjacent to exit 38 of raceway 26. If staple 33 strays out of raceway 26 during the driving stroke ramps 37 urge it back into proper alignment. Ramps 37 also cooperate with raceway 26 to form exit 38 which exit guides and orients staple 33 as its full length passes through the exit.
  • magazine 14 is opened and staplestick 19 inserted for urging (to the left as shown in Fig. 1) by spring 25 toward and against raceway 26. Due to the angle between staplestick 19 and raceway 26 and the force of spring 25, the end of stick 19 is urged downwardly against stud 29. If stud 29 is not used in the tool other means for holding staplestick 19 in contact with raceway 26 are required.
  • Staplestick 19 having staple 33 at its left handed end (as shown in Fig. 2) abuts raceway 26 with the crown 39 of staple 33 adjacent stud 29.
  • raceway 26 The length of raceway 26 and spacing between where driver blade 21 first strikes staple 33 and ramps 37 permits tool 10 to drive staples having longer legs than those shown in Figs. 2 and 3.
