Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
237 words
An apparatus for driving fasteners comprising: a body having a reciprocally movable drive means for driving successive fasteners supplied from a magazine assembly, a magazine assembly including a support structure mounted on said body adapted to receive an elongated, interchangeable cartridge means holding a plurality of fasteners in side-byside relation adapted to be fed therefrom and into successive driving engagement with said drive means, and a nos assembly mounted on said body having a guide structure means for receiving fasteners delivered from said cartridge means, said nose assembly including retainer means disposed interiorly thereoF for successively controlling the movement of fasteners into said guide structure means from said cartridge means, said retainer means including a resiliently mounted element adapted to be yieldably pivoted in one direction upon engagement by a respective one of said fasteners upon its movement into said guide structure means and a stop means disposed interiorly adjacent the juncture of said cartridge means and said nose assembly in the path of movement of said fasteners to prevent the same from entering said guide structure means in an inverted position thereof, said drive means including a drive member having an integral blade portion disposed for reciprocal movement through said guide means structure for pushing engagement with the confronting surfaces of said fasteners for feeding said fasteners outwardly through said guide means structure and yieldably past said retainer means into secured engagement with a work piece.
Claim 2
Independent Claim
237 words
An apparatus for driving fasteners comprising: a body having a reciprocally movable drive means for driving successive fasteners supplied from a magazine assembly, a magazine assembly including a support structure mounted on said body adapted to receive an elongated, interchangeable cartridge means holding a plurality of fasteners in side-byside relation adapted to be fed therefrom and into successive driving engagement with said drive means, and a nos assembly mounted on said body having a guide structure means for receiving fasteners delivered from said cartridge means, said nose assembly including retainer means disposed interiorly thereoF for successively controlling the movement of fasteners into said guide structure means from said cartridge means, said retainer means including a resiliently mounted element adapted to be yieldably pivoted in one direction upon engagement by a respective one of said fasteners upon its movement into said guide structure means and a stop means disposed interiorly adjacent the juncture of said cartridge means and said nose assembly in the path of movement of said fasteners to prevent the same from entering said guide structure means in an inverted position thereof, said drive means including a drive member having an integral blade portion disposed for reciprocal movement through said guide means structure for pushing engagement with the confronting surfaces of said fasteners for feeding said fasteners outwardly through said guide means structure and yieldably past said retainer means into secured engagement with a work piece.
Claim 3
Dependent Claim
128 words
A pressurized fluid operated apparatus for driving fasteners received from an interchangeable cartridge having an integral fluid operated fastener feeding plunger therein, said apparatus comprising: a body having a reciprocally movable drive means for driving successive fasteners received from said cartridge, said body having a chamber for connection to a source of pressurized fluid, said chamber selectively connected to said drive means for driving said fasteners, and a cartridge receiving assembly for mounting said cartridge to said body, said assembly including a closure member movable into and out of fluid sealing relation with said cartridge, said assembly having a fluid passageway for supplying fluid from said chamber to said cartridge for actuation of said plunger only when said closure member is in fluid sealing relation, with said cartridge.
Claim 4
Dependent Claim
128 words
A pressurized fluid operated apparatus for driving fasteners received from an interchangeable cartridge having an integral fluid operated fastener feeding plunger therein, said apparatus comprising: a body having a reciprocally movable drive means for driving successive fasteners received from said cartridge, said body having a chamber for connection to a source of pressurized fluid, said chamber selectively connected to said drive means for driving said fasteners, and a cartridge receiving assembly for mounting said cartridge to said body, said assembly including a closure member movable into and out of fluid sealing relation with said cartridge, said assembly having a fluid passageway for supplying fluid from said chamber to said cartridge for actuation of said plunger only when said closure member is in fluid sealing relation, with said cartridge.
Claim 5
Dependent Claim
42 words
The apparatus of claim 2 wherein said cartridge receiving assembly additionally comprises: means for biasing said closure member into fluid sealing relation with said cartridge; and valve means for closing said passageway when said closure member is moved out of said relation.
Claim 6
Dependent Claim
39 words
The apparatus of claim 3 wherein said closure member includes a resilient pad having a fluid transmitting aperture therethrough, said pad sealingly engaging one end of said cartridge when said closure member is in sealing relation with said cartridge.
Claim 7
Dependent Claim
51 words
An apparatus in accordance with claim 3 including: a nose assembly mounted on said body having a guide structure means for receiving fasteners delivered from said cartridge means and a retainer means disposed interiorly thereof for successively controlling the movement of fasteners into said guide structure means from said cartridge means.
