Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
271 words
A survival device, comprising a substantially L-shaped single-piece body having discreet first and second legs disposed and joined substantially at right angles to one another so that each of said legs has one free end and one end jointed to said other leg, each of said first and second legs having removably associated with said free end thereof at least one survival tool that requires, for efficient use thereof, use of said second and first legs, respectively, as the handle therefor, each of said legs being formed lengthwise thereof to provide a storage chamber therein, each of said storage chambers having one permanentlyclosed bottom end and one open end with removable means for sealing the same, the chamber of said second leg opening at the free end of said second leg and the chamber of said first leg opening at the end thereof joined to said second leg, whereby said closed bottom end of said chamber of said second leg is disposed adjacent but spaced from said open end of said chamber in said first leg and said closed bottom end of said chamber of said first leg is spaced from said free end of said first leg, said chambers being internally threaded and said chamber sealing means comprising externally threaded plugs threadable into said chambers, said plugs having oppositely disposed flats formed on the outer circumference thereof to enable the same to be more easily removed and replaced without use of tools, and said plugs being hollow from the inner ends thereof so as to increase the length and volume of said chambers when said plugs are in chamber-sealing position.
Claim 2
Dependent Claim
271 words
A survival device, comprising a substantially L-shaped single-piece body having discreet first and second legs disposed and joined substantially at right angles to one another so that each of said legs has one free end and one end jointed to said other leg, each of said first and second legs having removably associated with said free end thereof at least one survival tool that requires, for efficient use thereof, use of said second and first legs, respectively, as the handle therefor, each of said legs being formed lengthwise thereof to provide a storage chamber therein, each of said storage chambers having one permanentlyclosed bottom end and one open end with removable means for sealing the same, the chamber of said second leg opening at the free end of said second leg and the chamber of said first leg opening at the end thereof joined to said second leg, whereby said closed bottom end of said chamber of said second leg is disposed adjacent but spaced from said open end of said chamber in said first leg and said closed bottom end of said chamber of said first leg is spaced from said free end of said first leg, said chambers being internally threaded and said chamber sealing means comprising externally threaded plugs threadable into said chambers, said plugs having oppositely disposed flats formed on the outer circumference thereof to enable the same to be more easily removed and replaced without use of tools, and said plugs being hollow from the inner ends thereof so as to increase the length and volume of said chambers when said plugs are in chamber-sealing position.
Claim 3
Dependent Claim
58 words
A device such as that recited in claim 1, wherein said first-leg tool is a combination saw-knife, said saw-knife tool being removably retained in a slot formed in said free end of said first leg, said first leg serving as the handle when using said knife and said second leg serving as the handle when using said saw.
Claim 4
Dependent Claim
50 words
A device such as that recited in claim 2, wherein said second-leg tool is hammer, the striking hammerhead comprising a plug with a flat outer end face threadable into engagement with threads formed on said free end of said second-leg to sealably close said chamber formed in said second leg.
Claim 5
Dependent Claim
54 words
A device such as that recited in claim 1, wherein said chamber in said first leg is sealably closed by a threaded plug having compass means secured thereto, said plug having pliable carrying means thereon adapted to carry said device when said plug is assembled or only said compass when said plug is removed.
Claim 6
Dependent Claim
88 words
A device such as that recited in claim 1, wherein one surface of said first leg is formed with a channel terminating in a cavity extending into the adjacent outer surface of said second leg, a penlight disposed in said channel and having one end retained in said cavity, the lamp end of said penlight being retained near the free end of said first leg by removable means, whereby the light is directed at the work so that knife cutting and sawing may be done in the dark.
Claim 7
Dependent Claim
51 words
A device such as that recited in claim 1, wherein at least one of said legs is externally formed with a recess having undercut edges, said recess having disposed therein an element such as a whetstone or a signalling mirror having mating edges for retention of said element on said device.
