Definitions

  • This invention relates generally to a novel magazine assembly for a fastener driving tool which includes features that provide for quick and efficient opening of the magazine in the event a fastener becomes deformed and becomes jammed in the nosepiece of the tool and for preventing operation of the tool when desired or when there are but a few fasteners remaining in the magazine.
  • Fastener driving tools of various kinds are well known to those skilled in the art. These include pneumatic and electrically operated tools as well as other types of tools that are designed for continuous operation and thus include a magazine that holds a plurality of fasteners. The magazine is designed to sequentially introduce a fastener into position to be driven.
  • Various types of magazines have been employed such as those shown in U.S. patents 3,207,405 and 3,815,475 assigned to the assignee of the present invention. These magazines perform satisfactorily but unfortunately there occasionally occurs jamming resulting from a bent nail or some other foreign material which results in the nail becoming stuck in the nosepiece of the tool thus preventing operation thereof.
  • a novel magazine which includes a portion thereof that forms the guideway for the fastener being driven.
  • This magazine is mounted relative to the nose portion of the main body of the tool and can readily be moved relative thereto so that any fastener jammed therein can be readily withdrawn.
  • a mechanism which restricts movement of the work sensitive probe assembly and thus prevents operation of the tool when operation is not desired or when there are but a few fasteners remaining in the magazine. This is accomplished by having the follower that normally acts to bias the nails into position in the nosepiece contact a lock out bracket when desired or automatically when there are but a few nails remaining in the magazine.
  • the lock out bracket is moved into position to halt movement of the work sensitive probe assembly which thus prevents firing of the tool and immediately brings to the attention of the operator that he is about to run out of fasteners and that they should be replenished.
  • the follower is retracted and the lock out bracket which is normally spring-biased into a disengaged position is moved out of contact with the work sensitive probe to permit normal operation of the tool.
  • FIG. 1 there is shown in general outline form a fastener driving tool that is powered by the pressure produced by the combustion of a fuel and air mixture.
  • This type of tool is by way of example only since the novel magazine assembly disclosed herein can be employed with various types of fastener driving tools including those that are pneumatically and electrically operated. Only those general details of the tool that relate to the present invention will be dealt with herein. Further details of the illustrated tool as set forth in an application entitled “Portable Gas Powered Fastener Driving Tool", Serial No. 402,770, filed July 28, 1982 and assigned to the assignee of the present invention.
  • the types of tools to which the present applies include those that have a magazine secured thereto which magazine is adapted to receive a plurality of fasteners such as nails that are sequentially biased into position to be driven into a workpiece by a driver secured to a driving piston operated by high pressure air, combustion gases or other energy sources.
  • the mechanism whereby the magazine assembly can be readily spaced from the nose portion of the tool to remove a fastener that may be jammed in the nosepiece and (2) a mechanism for preventing operation of the tool when operation is not desired or when there are no fasteners or a small number of fasteners i.e. 4 or 6 in the magazine.
  • the fastener driving tool need not include a work sensitive probe assembly whereby the tool will only operate when the nosepiece is placed in contact with the workpiece.
  • a fastener driving tool 12 having a main body portion 14 and a handle portion 16. Located below the main body portion 14 is a nose portion 18 and downwardly disposed from the handle portion 16 is a foot portion 20.
  • the novel magazine assembly 22 is secured at its rear portion to the foot portion 20 and the front end thereof is disposed adjacent the nose portion 18.
  • a strip of nails 24 which is biased into position in the nosepiece by a follower 26, which follower is biased against the nail strip by a conventional constant force spring assembly 28.
  • the tool is operated by actuation of the trigger 30 which effects movement of the driving piston 32 and associated driver blade 34 that extends through the nosepiece 18.
  • the operation of the trigger 30 is controlled by the work sensitive probe assembly 36.
  • the trigger 30 cannot be fired unless the work sensitive probe assembly is moved upwardly relative to the nosepiece 18 to effect release of a trigger interlock assembly 38, the details of which are not important to an understanding of the present invention.
  • the interrelationship between the illustrated trigger and work sensitive probe assembly reference is made to the aforementioned application entitled Portable Gas Powered Fastener Driving Tool, Serial No. 402,770.
  • the novel lockout feature of the magazine disclosed herein can be used in conjunction with any of various types of work sensitive probe assemblies and associated trigger interlock mechanisms so long as the trigger cannot be operated unless the probe assembly moves relative to the nose assembly a predetermined amount.
  • the trigger mechanism employed herein is to effect operation of a gas fired tool it can also be employed to control a valve mechanism to admit high pressure air to drive the piston or control the operation of an electrically controlled tool.
  • the force used to drive the piston is not critical so long as the trigger controls the application of such force.
  • FIG 2 there is shown as an enlarged view of the magazine, the main portion of which is supported relative to the nosepiece by a pair of pins 40 extending into openings 42 formed in the fixed nose guide 18 (only one pin and opening are illustrated).
  • the magazine is loaded with fasteners 24 with the follower 26 being located in the retracted position as shown in Figure 5B.
  • the rear end of the magazine is supported relative to the foot portion 20 of the handle 16 of the driver tool by the interengagement of serrated teeth 44, 46 formed on members 45 and 47 secured to the foot portion 20 and magazine 22 respectively (see Figure 3).
  • the serrated teeth 44, 46 are retained in locking engagement by a threaded knob assembly 50 and associated nut 52.
  • the foot portion 20 defines an elongated slot 54 in which the knob assembly 50 is free to slide.
  • the knob 50 is loosened to permit separation of the toothed members as shown in Figure 3
  • the magazine 22 can be moved to the right into the position shown in Figure 2.
  • the magazine and associated pins 40 are moved relative to the nosepiece with the result that a gap 56 is provided between the nose guide portion and the adjacent end of the magazine to permit removal of any fastener that may be jammed therein.
  • the magazine can be moved to the left and the serrated teeth reengaged by tightening of the threaded knob assembly 50 to lock the magazine in position adjacent the nose guide.
  • Bracket 60 is free to move relative to fastener 63 and is normally held in the position shown in Figure 2 by a spring 61 located between an abutment (not shown) on the magazine and a downwardly turned flange 64 on the lock out bracket.
  • a spring 61 located between an abutment (not shown) on the magazine and a downwardly turned flange 64 on the lock out bracket.
  • FIGs 5A and 5B there is illustrated two positions of the follower assembly 26.
  • the follower has been moved to by-pass the nail strip and thus the constant force spring will move the follower into contact with the lockout bracket to prevent firing of the tool even though there are nails in the magazine. This is done when it is desired to lock the probe in position when the tool is being transported or not in use.
  • Figure 5B shows the follower 26 in position to bias nails into position to be driven. In this operation the lockout bracket will not be contacted until there remains but a few nails in the magazine.
