Abstract
Abstract A light weight readily adaptable plastic device to stop rotation of the cylinder of a revolver is presented having an arcuate pawl which contacts the gun frame as rotation of the cylinder is attempted, for example, by pulling the trigger. The device includes a semi-hexagonally shaped pawl with a pair of depending cylinder studs which will engage two of the shell chambers in a gun cylinder and which will allow shells to occupy the remaining chambers.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
A cylinder lock device for a gun cylinder comprising: a chamber stud, a pawl, said pawl connected to said chamber stud, said pawl having a radial section, said radial section extending outwardly beyond said cylinder when said chamber stud is positioned in a cylinder chamber whereby said radial section will stop the cylinder rotation to prevent the gun from firing.
Claim 2
Dependent Claim
60 words
A cylinder lock device for a gun cylinder comprising: a chamber stud, a pawl, said pawl connected to said chamber stud, said pawl having a radial section, said radial section extending outwardly beyond said cylinder when said chamber stud is positioned in a cylinder chamber whereby said radial section will stop the cylinder rotation to prevent the gun from firing.
Claim 3
Dependent Claim
16 words
A cylinder lock as claimed in claim 1 wherein said chamber stud comprises a cylindrical member.
Claim 4
Dependent Claim
15 words
A cylinder lock as claimed in claim 1 wherein said pawl comprises a planar member.
Claim 5
Dependent Claim
15 words
A cylinder chamber as claimed in claim 3 wherein said planar member is arcuately shaped.
Claim 6
Dependent Claim
14 words
A cylinder lock as claimed in claim 1 wherein said pawl is semi-hexagonally shaped.
Claim 7
Dependent Claim
15 words
A cylinder lock as claimed in claim 1 and including a pair of chamber studs.
Claim 8
Dependent Claim
19 words
A cylinder lock as claimed in claim 1 and including a pawl tab, said tab affixed to said pawl.
Claim 9
Dependent Claim
102 words
A lock for a rotating gun cylinder, said cylinder positioned within a frame to prevent the cylinder from adequately rotating while the cylinder is closed comprising: semi-hexagonally shaped planar pawl, said pawl including a radial section, a pair of cylinder studs, said studs being elongated and spaced along one side of said planar pawl near the middle thereof so each stud will fit into separate shell chambers of the cylinder and said radial section will extend beyond the periphery of the cylinder whereby said radial section, will contact the cylinder frame and stop the cylinder rotation thereby preventing the gun from firing.
Claim 10
Dependent Claim
102 words
A lock for a rotating gun cylinder, said cylinder positioned within a frame to prevent the cylinder from adequately rotating while the cylinder is closed comprising: semi-hexagonally shaped planar pawl, said pawl including a radial section, a pair of cylinder studs, said studs being elongated and spaced along one side of said planar pawl near the middle thereof so each stud will fit into separate shell chambers of the cylinder and said radial section will extend beyond the periphery of the cylinder whereby said radial section, will contact the cylinder frame and stop the cylinder rotation thereby preventing the gun from firing.
Claim 11
Dependent Claim
101 words
A cylinder lock for use with a gun having a rotatable cylinder with shell chamber therein comprising: a planar pawl, said pawl having an upper radially extending section, a central section and a lower radially extending section, said upper and lower sections joined to said central sections, a cylinder stud, said stud attached to said pawl, said stud for positioning within a shell chamber, said upper and said lower section extending beyond the periphery of said cylinder when said cylinder stud is positioned within a shell chamber, whereby said pawl will prevent sufficient cylinder rotation to allow the gun to fire.
Claim 12
Dependent Claim
101 words
A cylinder lock for use with a gun having a rotatable cylinder with shell chamber therein comprising: a planar pawl, said pawl having an upper radially extending section, a central section and a lower radially extending section, said upper and lower sections joined to said central sections, a cylinder stud, said stud attached to said pawl, said stud for positioning within a shell chamber, said upper and said lower section extending beyond the periphery of said cylinder when said cylinder stud is positioned within a shell chamber, whereby said pawl will prevent sufficient cylinder rotation to allow the gun to fire.
