Abstract
Abstract A key of which the longitudinally extending grooves which code the key for insertion into the key receiving passage of a lock, extend both through the stem of the key which is inserted into the passage, and through the manipulating head part of the key so that the key blank can be produced by a stamping or pressing operation. There is also described a method of making the key.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
176 words
A key comprising a manipulating head part and an integral lock operating part for insertion into a key receiving slot of a lock, an integral connecting part extending the full length of the key and connecting portions of said head part and said operating part on opposite sides thereof, said portions of said head and operating parts on one side of the connecting part lying in a common plane and the portions of said head and operating part on the other side of said connecting part also lying in a common plane, said integral connecting part including a longitudinally extending section disposed in a plane offset from that plane common to said portions of said head and operating parts on said one side of said connecting part, and wherein an edge of at least one of said portion of said operating part most remote from said connecting part is coded by notching and constitutes means cooperating with tumbler elments of a lock when said operating part is inserted into a key receiving slot of a lock.
Claim 2
Dependent Claim
176 words
A key comprising a manipulating head part and an integral lock operating part for insertion into a key receiving slot of a lock, an integral connecting part extending the full length of the key and connecting portions of said head part and said operating part on opposite sides thereof, said portions of said head and operating parts on one side of the connecting part lying in a common plane and the portions of said head and operating part on the other side of said connecting part also lying in a common plane, said integral connecting part including a longitudinally extending section disposed in a plane offset from that plane common to said portions of said head and operating parts on said one side of said connecting part, and wherein an edge of at least one of said portion of said operating part most remote from said connecting part is coded by notching and constitutes means cooperating with tumbler elments of a lock when said operating part is inserted into a key receiving slot of a lock.
Claim 3
Dependent Claim
207 words
A key comprising a manipulating head part and an integral, operating part for insertion into a key receiving slot of a lock, said head part comprising first and second planar portions disposed on opposite sides of a longitudinally extending, integral connecting part, said operating part also comprising first and second planar portions disposed on opposite sides of a longitudinally extending integral connecting part, the planes of said portions of said head and operating part on one side of said respective connecting portions being coincidental and the planes of portions of said head and operating parts on the other side of said connecting portions being coincidental, said connecting portions of said head part and operating part being longitudinally aligned, an edge of at least one of said first and second portions of said operating part most remote from said longitudinally extending connecting part of said operating part being coded by notching and constituting means cooperating with tumbler elements of a lock when said operating part is inserted in a key receiving slot of a lock, said connecting parts of said head and operating parts including a common, longitudinally extending section disposed in a plane offset from the plane of said first portions of said head and operating parts.
Claim 4
Dependent Claim
207 words
A key comprising a manipulating head part and an integral, operating part for insertion into a key receiving slot of a lock, said head part comprising first and second planar portions disposed on opposite sides of a longitudinally extending, integral connecting part, said operating part also comprising first and second planar portions disposed on opposite sides of a longitudinally extending integral connecting part, the planes of said portions of said head and operating part on one side of said respective connecting portions being coincidental and the planes of portions of said head and operating parts on the other side of said connecting portions being coincidental, said connecting portions of said head part and operating part being longitudinally aligned, an edge of at least one of said first and second portions of said operating part most remote from said longitudinally extending connecting part of said operating part being coded by notching and constituting means cooperating with tumbler elements of a lock when said operating part is inserted in a key receiving slot of a lock, said connecting parts of said head and operating parts including a common, longitudinally extending section disposed in a plane offset from the plane of said first portions of said head and operating parts.
Claim 5
Dependent Claim
66 words
Apparatus as claimed in claim 2 wherein the plane in which portions of said head and operating parts on one side of said respective connecting portions lies is parallel to the plane in which said portions on the opposite sides of said connecting portions lies and wherein said connector part comprises a web portion interconnecting adjacent edges of said portions of said head and operating parts.
Claim 6
Dependent Claim
40 words
A key as claimed in claim 1 wherein said common planes are parallel and offset from one another and said connecting part comprises a web portion interconnecting adjacent edges of said portions of said head part and said operating part.
Claim 7
Dependent Claim
64 words
A key as claimed in claim 2 wherein the plane in which portions of said head and operating parts on one side of said respective connecting portions is disposed, intersects the plane in which said portions of said head and operating parts on the other side of said connecting parts are disposed, a line on which said planes intersect extending longitudinally of the key.
Claim 8
Dependent Claim
21 words
A key as claimed in claim 1 wherein said planes intersect one another on a line extending longitudinally of said key.
Claim 9
Dependent Claim
16 words
A key as claimed in claim 5 wherein said connecting portions have similar, curved transverse cross-sections.
Claim 10
Dependent Claim
18 words
A key as claimed in claim 1 wherein said connecting portion has a substantially constant, curved transverse cross-section.
Claim 11
Dependent Claim
22 words
A key as claimed in claim 2 wherein said first and second portions of said head part are disposed in different planes.
