Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 80 words
A gas cylinder carrier, comprising: a substantially rigid cylindrically-shaped member, sized to enclose only a portion of a gas cylinder, including a plurality of axially directed belt-receiving slots circumferentially positioned therein; a belt positioned in said slots and extending inside of said cylindrically-shaped member substantially along the chords defined between opposing slots of said member and outside of said member between the ends of said chords, and including means for tightening said belt to clamp said cylinder within said member.
Claim 2
Dependent Claim 80 words
A gas cylinder carrier, comprising: a substantially rigid cylindrically-shaped member, sized to enclose only a portion of a gas cylinder, including a plurality of axially directed belt-receiving slots circumferentially positioned therein; a belt positioned in said slots and extending inside of said cylindrically-shaped member substantially along the chords defined between opposing slots of said member and outside of said member between the ends of said chords, and including means for tightening said belt to clamp said cylinder within said member.
Claim 3
Dependent Claim 18 words
Apparatus as recited in claim 1 and further comprising a pair of handles attached to said cylindrically-shaped member.
Claim 4
Dependent Claim 38 words
Apparatus as recited in claim 1 and further comprising a second generally rigid cylindrically-shaped portion attached to said first-named cylindrically-shaped member and axially displaced therefrom, sized and positioned substantially to surround the nipple portion of a gas cylinder.
Claim 5
Dependent Claim 30 words
Apparatus as recited in claim 3 and further comprising a second handle upon the end of said second cylindrically-shaped portion for facilitating removal of a gas cylinder from said carrier.
Claim 6
Dependent Claim 169 words
A gas cylinder carrier, comprising: a substantially cylindrically-shaped member, sized to enclose at least a portion of a gas cylinder, including a plurality of axially directed belt-receiving slots circumferentially positioned therein; a belt positioned in said slots and extending inside of said cylindrically-shaped member substantially across at least one chord of said member and outside of said member between the ends of said chords, and including means to tighten said belt; means on said cylindrically-shaped member to prevent it from rolling when laid on its side; a pair of handles attached to said cylindrically-shaped member, said handles being flexibly attached to said cylindrically-shaped member; said cylindrically-shaped member being open in the region of and between said handles, said handles being substantially axially directed and having hand slots therein, said hand slots being formed in a pair of substantially axially-directed outwardly-extending tabs which Are flexibly attached to said cylindrically-shaped member, and two pair of circumferentially-directed relieving slots between the ends of said tabs and the body of said cylindrically-shaped member.
Claim 7
Dependent Claim 169 words
A gas cylinder carrier, comprising: a substantially cylindrically-shaped member, sized to enclose at least a portion of a gas cylinder, including a plurality of axially directed belt-receiving slots circumferentially positioned therein; a belt positioned in said slots and extending inside of said cylindrically-shaped member substantially across at least one chord of said member and outside of said member between the ends of said chords, and including means to tighten said belt; means on said cylindrically-shaped member to prevent it from rolling when laid on its side; a pair of handles attached to said cylindrically-shaped member, said handles being flexibly attached to said cylindrically-shaped member; said cylindrically-shaped member being open in the region of and between said handles, said handles being substantially axially directed and having hand slots therein, said hand slots being formed in a pair of substantially axially-directed outwardly-extending tabs which Are flexibly attached to said cylindrically-shaped member, and two pair of circumferentially-directed relieving slots between the ends of said tabs and the body of said cylindrically-shaped member.
Claim 8
Dependent Claim 32 words
Apparatus as recited in claim 5 in which said means to prevent said cylindrically-shaped member from rolling comprises a pair of axially directed ridges on the outer surface of said cylindrically-shaped member.
Claim 9
Dependent Claim 36 words
Apparatus as recited in claim 6 and further comprising a second cylindrically-shaped portion attached to said first-named cylindrically-shaped member and axially displaced therefrom, sized and positioned substantially to surround the nipple portion of a gas cylinder.
Claim 10
Dependent Claim 30 words
Apparatus as recited in claim 7 and further comprising a second handle upon the end of said second cylindrically-shaped portion for facilitating removal of a gas cylinder from said carrier.
Claim 11
Dependent Claim 26 words
Apparatus as recited in claim 8 in which said second handle comprises a diametrically directed loop extending substantially across the end of said second cylindrically-shaped portion.
Claim 12
Dependent Claim 18 words
Apparatus as recited in claim 9 in which said means for tightening said belt comprises an over-center toggle.
Claim 13
Dependent Claim 35 words
Apparatus as recited in claim 9 in which said first-named cylindrically-shaped member and said second cylindrically-shaped portion are integrally-formed and in which said second cylindrically-shaped portion is closed on its end adjacent said second handle.
Claim 14
Dependent Claim 48 words
Apparatus as recited in claim 11 in which said belt extends inside of said cylindrically-shaped member substantially across two chords of said member and outside of said member between the ends of said chords, and in which said belt-receiving slots are symmetrically positioned with respect to said handles.
Claim 15
Dependent Claim 15 words
Apparatus as recited in claim 12 in which said carrier is fabricated of plastics material.
Claim 16
