Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
In a bobbin having a core and adaptable for winding thereon a strand having a transverse and circumferential relative movement between said strand and said core, the improvement comprising a partition transversely mounted on said core and operative to receive and captively conduct said strand thereacross, said partition including obverse and reverse sides terminating in a peripheral edge circumferentially disposed about said core; a strand transferring surface in the form of a recess extending circumferentially and inwardly of said peripheral edge and defining an opening with said obverse side and said transferring surface forming a channel opening to said peripheral edge and conductively communicating said recess with said reverse side of said partition; an intercepting surface on said obverse side disposed in strand feeding relation to said transferring surface; and a lead surface on said obverse side disposed to guide said strand into receiving relation with said intercepting surface as said strand transversely engages said peripheral edge and relatively moves along said lead surface to said intercepting surface into said recess.
Claim 2
Dependent Claim
171 words
In a bobbin having a core and adaptable for winding thereon a strand having a transverse and circumferential relative movement between said strand and said core, the improvement comprising a partition transversely mounted on said core and operative to receive and captively conduct said strand thereacross, said partition including obverse and reverse sides terminating in a peripheral edge circumferentially disposed about said core; a strand transferring surface in the form of a recess extending circumferentially and inwardly of said peripheral edge and defining an opening with said obverse side and said transferring surface forming a channel opening to said peripheral edge and conductively communicating said recess with said reverse side of said partition; an intercepting surface on said obverse side disposed in strand feeding relation to said transferring surface; and a lead surface on said obverse side disposed to guide said strand into receiving relation with said intercepting surface as said strand transversely engages said peripheral edge and relatively moves along said lead surface to said intercepting surface into said recess.
Claim 3
Dependent Claim
113 words
A partition for separating windings on a core and operative to captively transfer thereacross a strand movable transversely and circumferentially relative of this partition, said partition comprising a peripheral edge circumferentially disposed about said core; lead means on said partition and engageable with the strand as it traverses against said partition; intercepting means on said partition disposed to interceptively receive the strand from said lead means as the strand moves circumferentially of said partition; and transfer means including a recessed surface extending inwardly from said edge to define an indentation therein extending generally circumferentially so as to be operative for captively conducting the strand from one side of the partition to the other.
Claim 4
Dependent Claim
113 words
A partition for separating windings on a core and operative to captively transfer thereacross a strand movable transversely and circumferentially relative of this partition, said partition comprising a peripheral edge circumferentially disposed about said core; lead means on said partition and engageable with the strand as it traverses against said partition; intercepting means on said partition disposed to interceptively receive the strand from said lead means as the strand moves circumferentially of said partition; and transfer means including a recessed surface extending inwardly from said edge to define an indentation therein extending generally circumferentially so as to be operative for captively conducting the strand from one side of the partition to the other.
Claim 5
Dependent Claim
48 words
The invention as recited in claim 2 wherein said lead means comprises a feed surface obliquely disposed relative to said core on said one side of said partition, said feed surface extending partially about said peripheral edge and terminating to form a common edge with said recessed surface.
Claim 6
Dependent Claim
41 words
The invention as recited in claim 3 wherein said intercepting means comprises a guide surface radially disposed in contiguous flanking relation to said recessed surface and forming therewith a strand intercepting edge transversely disposed in spaced relation to said common edge.
Claim 7
Dependent Claim
40 words
The invention as recited in claim 4 wherein said guide surface extends to said peripheral edge whereat said intercepting edge forms a distal end therewith, and said end projects outwardly from said core a distance greater than said common edge.
Claim 8
Dependent Claim
34 words
The invention as recited in claim 1 wherein said intercepting surface being disposed contiguous with said transferring surface at said recess to form thereat a radially extending strand guiding edge disposed adjacent said channel.
Claim 9
Dependent Claim
67 words
The invention as recited in claim 6 wherein saiD lead surface being disposed angularly to said core in slanted orientation from said peripheral edge to said obverse side, said lead surface extending partially about said peripheral edge and terminating at said opening to form an edge with said transferring surface, and said edge disposed across said recess from said radially extending edge in a transverse disposition therewith.
Claim 10
Dependent Claim
34 words
The invention as recited in claim 7 wherein said strand guiding edge terminated in an outwardly projecting distal end which radially extends beyond said edge formed by said lead surface with said transferring surface.
Claim 11
Dependent Claim
72 words
The invention as recited in claim 7 wherein said partition includes a beveled surface sloping from said obverse side to said channel at said peripheral edge and extending therealong to said transferring and intercepting surface, said beveled, intersecting and transferring surface forming a trihedron defining a common end point disposed on said radially extending edge whereat said point lies radially beyond said edge formed by said lead surface with said transferring surface.
Claim 12
Dependent Claim
95 words
The invention as recited in claim 7 wherein said channel extending from said recess in substantial parallelism between said obverse and reverse sides and terminating at a distance spaced from said recess and that portion of said reverse side adjacent said channel to form thereat a rear wall defining a continuous rear surface of one side of said channel and said recess, and said rear wall curving inwardly toward said core to produce an arcuate outwardly disposed and inwardly curving edge terminating substantially at that termination of said channel which is spaced from said recess.
Claim 13
Dependent Claim
53 words
The invention as recited in claim 9 wherein said partition includes a relief surface having an angular orientation from said reverse side toward said channel, said relief surface terminating at a fold line having the lower part thereof coincidental with the termination of said channel and inwardly curving edge of said rear wall.
Claim 14
Dependent Claim
38 words
The invention as recited in claim 11 wherein said partition includes a wiping surface slanting from said peripheral edge to said reverse side in angular orientation therewith, said wiping surface extending in intersecting relation with said relief surface.
