Definitions

  • This invention relates to portable fastener driving tools which drive fasteners seriatim using a recipro ⁇ cating blade and include a magazine housing lower sur ⁇ face 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 reci- provating blade to permit the tool to be positioned for driving in heretofore inaccessible corners or other areas.
  • U.S. Patent 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.
  • the invention comprises a portable fastener driving ttol having a reciprocating driver blade and a fastener magazine in which the fastenerstick is posi ⁇ tioned 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 fastener ⁇ stick by the force of the driver blade.
  • fastener ramps adja ⁇ cent the exit opening ⁇ f the tool urge the fastener back into the raceway, if it has moved out of the raceway, to assure proper alignment of the fastener as the fastener exits the tool.
  • Fastener ramps, together with the race- 5 way define an exit opening which guides the full length of the fastener as it moves through the opening into the workpiece.
  • a retractable detent may be positioned in the raceway which detent serves to assist 0 in orienting the first-to-be-driven fastener as the blade strickes and moves such fastener during the driving stroke and also serves to support the fastenerstick during load ⁇ ing of the magazine.
  • a retractable detent is not required when driving fasteners having heads or crowns which are 5 wide or otherwise shaped so that the driver blade striking them will properly orient them; however, with fasteners which are not properly oriented by the driver blade a detent is required.
  • detents may 0 be used. Additional detents are positioned below the detent shown in the drawings and operate in the same manner to re-orient as necessary the fastener as it moves down the raceway.
  • Fig. 1 is a side elevational view of the staple driving unit partially broken away;
  • Fig. 2 is an enlarged side view partially broken away to show a portion of the internal mechanism
  • Fig. 3 is an another enlarged side view broken away to show the mechanism of Fig. 2 in another stage of its operation;
  • Fig. 4 is a sectional view alongsline 4-4 of Fig. 2.
  • 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.
  • Be ⁇ low 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 29 may be positioned below and tangent to the crown 39 of the staple 33, as shown in the drawings, or ay 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 to ⁇ ward and against raceway 26. Due the angle between staple- stick 19 and raceway 26 and the force of spring 25, the end of stick 19 is urged downwardly against stud 29. If stud 19 is not used in the tool other means for holding staplestick 19 in contact with raceway 26 are required.
  • driver blade 21 descends staple 33 is removed from staplestick 19; oriented in raceway 26 and driven in the following manner; 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. 5

Abstract

Un instrument portatif d'entrainement d'elements d'attache (10) possede un caniveau (26) avec une lame d'entrainement (21) ayant un mouvement de va-et-vient a l'interieur depuis une position retractee vers une position d'elements d'attache entraines pour entrainer les elements d'attache (33) successivement a partir d'une baguette d'elements d'attache (19) positionnee suivant un angle aigu par rapport au caniveau. Le premier element d'attache a etre entraine (33), tout en etant fixe a la baguette (19), est positionne dans le caniveau (26) de maniere telle que la lame descendante (21) serve a orienter l'element d'attache (33) vers une position sensiblement parallele au caniveau (26) pour effectuer un entrainement vers le bas et hors du caniveau, dans la piece de travail. Des moyens de rampe (37,46) qui font partie de l'ouverture de sortie de l'instrument(38) reorientent l'element d'attache (33) comme cela est necessaire et le guident pendant sa sortie. La baguette d'elements d'attache (19) peut etre supportee dans le caniveau (26) par des moyens de tenon de detente (29, 31) qui se retractent du caniveau (26) lorsque l'agrafe (33) descend.
