Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
262 words
A tool that holds clips of nails and operates to individually eject the nails for driving the nails into base members: said tool comprising magazine means adapted to receive an integrally connected strip of apertured wing headed fasteners for use in removably attaching first members such as cabinet backings to said base members; said magazine having a characterized aperture means shaped to enable passage therethrough of individual ones of said wing headed fasteners; said characterized aperture means located in the path of said driven nails; feeding means for automatically placing successive ones of the wing headed fasteners of the strip into position in said characterized aperture with the aperture of the wing headed fastener in the path of the driven nails; means for separating the positioned wing head fastener from said strip to enable the separated wing headed fastener to pass through said characterized aperture and be fastened to said base member by said driven nails; a first protrusion resiliently mounted on said tool means and located to the rear of said characterized aperture; a second protrusion means resiliently mounted on said tool means and located to the front of said characterized aPerture; said first and second protrusion means each having a normal downwardly extended position for aligning said characterized aperture with slots in said first members and an upward retracted position; normally disabled trigger means for selectively operating the tool to drive individual ones of said nails; and enabling means operated responsive to the said first or second protrusion means being in the upward retracted position for enabling said trigger means.
Claim 2
Dependent Claim
262 words
A tool that holds clips of nails and operates to individually eject the nails for driving the nails into base members: said tool comprising magazine means adapted to receive an integrally connected strip of apertured wing headed fasteners for use in removably attaching first members such as cabinet backings to said base members; said magazine having a characterized aperture means shaped to enable passage therethrough of individual ones of said wing headed fasteners; said characterized aperture means located in the path of said driven nails; feeding means for automatically placing successive ones of the wing headed fasteners of the strip into position in said characterized aperture with the aperture of the wing headed fastener in the path of the driven nails; means for separating the positioned wing head fastener from said strip to enable the separated wing headed fastener to pass through said characterized aperture and be fastened to said base member by said driven nails; a first protrusion resiliently mounted on said tool means and located to the rear of said characterized aperture; a second protrusion means resiliently mounted on said tool means and located to the front of said characterized aPerture; said first and second protrusion means each having a normal downwardly extended position for aligning said characterized aperture with slots in said first members and an upward retracted position; normally disabled trigger means for selectively operating the tool to drive individual ones of said nails; and enabling means operated responsive to the said first or second protrusion means being in the upward retracted position for enabling said trigger means.
Claim 3
Dependent Claim
126 words
The tool of claim 1 wherein said enabling means comprises safety catch means slidably attached to the handle of said tool: said safety catch means having a normal lower position and an upward position; pivot means at one end of said trigger means for pivotally attaching said trigger to said tool; tool actuation means encompassed by said trigger means; lever means for abutting said actuation means pivotally attached to said trigger means; stop means on said trigger means to prevent said lever means from abutting said actuation means unless said lever means is pivoted upward; and finger means on said safety catch means juxtaposed to the unpivoted end of said lever to pivot said lever upward when said safety catch is in the forced upward position.
Claim 4
Dependent Claim
126 words
The tool of claim 1 wherein said enabling means comprises safety catch means slidably attached to the handle of said tool: said safety catch means having a normal lower position and an upward position; pivot means at one end of said trigger means for pivotally attaching said trigger to said tool; tool actuation means encompassed by said trigger means; lever means for abutting said actuation means pivotally attached to said trigger means; stop means on said trigger means to prevent said lever means from abutting said actuation means unless said lever means is pivoted upward; and finger means on said safety catch means juxtaposed to the unpivoted end of said lever to pivot said lever upward when said safety catch is in the forced upward position.
Claim 5
Dependent Claim
20 words
The tool of claim 2 wherein resilient means are provided to maintain said safety catch in the normal lower position.
Claim 6
Dependent Claim
116 words
The tool of claim 3 and a bottom plate means positioned on the bottom of said tool adjacent said characterized aperture, said first protrusion means extending downwardly from said bottom plate means: reciprocating bottom plate piston means extending through said magazine means and fixedly attached to said bottom plate means; bottom plate spring means surrounding said bottom plate piston means between said magazine means and said bottom plate means for maintaining said bottom plate in a normally downwardly extending position; and said bottom plate piston means being of sufficient length to abut said enabling means to force said enabling means to the upward position when said bottom plate is pushed upward to juxtapose said magazine means.
Claim 7
Dependent Claim
106 words
The tool of claim 4 wherein fastening plate means are provided at the front of said tool means for use in attaching said magazine means to said tool: said fastening plate means having a characterized cylinder receiving aperture at the bottom thereof; cylinder means reciprocatingly mounted in said cylinder receiving aperture; said second protrusion fixedly attached to and extending downward from the bottom of said cylinder; said cylinder having a normal downward position and an upward position; and tab means on said enabling means maintained juxtaposed to the top of said cylinder whereby when said cylinder is forced upward so is said enabling means forced upward.
Claim 8
Dependent Claim
81 words
The tool of claim 5 wherein said separating means comprises first cutting means extending upward from said bottom plate whereby when said bottom plate is forced upward said first cutting means is positioned to cut the gate between consecutive wing headed fasteners from the body of the fastener positioned in the characterized aperture; and wherein trimming means are provided at the other side of said characterized aperture to trim the remains of the gate from the fastener in the characterized aperture.
Claim 9
Dependent Claim
53 words
The tool of claim 6 wherein said trimming means comprises slot means in said cylinder: said slot means having a sharp lower edge; and wherein said cylinder receiving aperture positions said cylinder to receive the remains of said gate in said slot means when a wing headed fastener is in said characterized aperture.
Claim 10
Dependent Claim
35 words
The tool of claim 7 wherein said safety catch comprises a main body section; table top means extending normally to said main body section and positioned to be abutted by said reciprocating bottom plate pistons.
Claim 11
Dependent Claim
47 words
The tool of claim 8 wherein said means for holding said safety catch in a normally downwArd position comprises pin means extending downward from said handle through said tab means; pin spring means surrounding said post means and held compressed between said handle and said tab means.
Claim 12
Dependent Claim
49 words
The tool of claim 8 wherein said means for holding said cylinder means in a normally downward position comprises: an axial hole extending downward from the top of said cylinder; spring means in said hole; and wherein said pin means extends into said hole to compress said spring means.
