Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
165 words
A takedown reel comprising, a pair of substantially identical rectangular resilient drum-forming plates; a pair of parallel hinges connecting opposite edges of one plate with the corresponding opposite edges of the other plate, said drumforming plates being normally flattened in an inoperative position thereof, said drum-forming plates being resiliently deformable into the form of a drum, whose axis is parallel to the hinges, by bending each plate in the form of a semicircle representing one half of the drum and hinged to another semicircle formed by the other plate; and a pair of flanges, each having a circular hub means to fit the inner peripheral edge at either end of the drum made by bending the drum-forming plates, whereby a reel is formed by bending the drum-forming plates in the drum form and fitting the flanges at longitudinally opposite ends of the drum while allowing folding of the reel into a compact form by separating the drum from the flanges and flattening the drum plates.
Claim 2
Dependent Claim
165 words
A takedown reel comprising, a pair of substantially identical rectangular resilient drum-forming plates; a pair of parallel hinges connecting opposite edges of one plate with the corresponding opposite edges of the other plate, said drumforming plates being normally flattened in an inoperative position thereof, said drum-forming plates being resiliently deformable into the form of a drum, whose axis is parallel to the hinges, by bending each plate in the form of a semicircle representing one half of the drum and hinged to another semicircle formed by the other plate; and a pair of flanges, each having a circular hub means to fit the inner peripheral edge at either end of the drum made by bending the drum-forming plates, whereby a reel is formed by bending the drum-forming plates in the drum form and fitting the flanges at longitudinally opposite ends of the drum while allowing folding of the reel into a compact form by separating the drum from the flanges and flattening the drum plates.
Claim 3
Dependent Claim
30 words
A takedown reel according to claim 1, further comprising at least one bolt member disposed within the drum and extending longitudinally therein and detachably fastening said flanges to said drum.
Claim 4
Dependent Claim
18 words
A takedown reel according to claim 2, wherein each flange has inner and outer rims integrally secured thereto.
Claim 5
Dependent Claim
74 words
A takedown reel according to claim 1, wherein each of said pair of hinges consists of two sets of interengaging serrations formed along abutting edges of the two drum-forming plates, each set of serrations having alternately disposed teeth and spaces, the teeth of each set being rolled and alternately fitted into the spaces of the other set, and a pin penetrating through the teeth of the two sets to swingably connect the two plates.
Claim 6
Dependent Claim
27 words
A takedown reel according to claim 1, wherein each of said pair of hinges consists of a separate hinge secured to abutting edges of the two plates.
Claim 7
Dependent Claim
15 words
A takedown reel according to claim 1, wherein said drum-forming plates are made of steel.
Claim 8
Dependent Claim
14 words
A takedown reel according to claim 1, wherein said flanges are made of steel.
Claim 9
Dependent Claim
58 words
A takedown reel according to claim 2, wherein said hub of each flange has a pair of axially extending recesses formed at diametrically opposite positions thereof for receiving the hinges connecting the two drum-forming plates, when the plates are curved in the form of the drum and the hinges are disposed at diametrically opposite portions of the drum.
Claim 10
Dependent Claim
58 words
A takedown reel according to claim 2, wherein said hub of each flange has a pair of axially extending slots formed at diametrically opposite positions thereof for receiving the hinges connecting the two drum-forming plates when the plates are curved in the form of the drum and the hinges are disposed at diametrically opposite portions of the drum.
Claim 11
Dependent Claim
26 words
A takedown reel according to claim 1, wherein said pair of hinges are axially shorter than the full width of the plates between the two flanges.
