Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
A creel to supply yarn to a yarn consuming machine comprising: a frame, means to rotate a plurality of yarn beams mounted in said frame, means to support a plurality of yarn beams operably associated with said frame, means to supply yarn from the yarn beams to the yarn consuming machine mounted on said frame and means to move said yarn beam support means into and out of operative relationship with said means to rotate the yarn beams, said means to support yarn beams including a pair of elongated beams pivotally mounted in said creel.
Claim 2
Dependent Claim
95 words
A creel to supply yarn to a yarn consuming machine comprising: a frame, means to rotate a plurality of yarn beams mounted in said frame, means to support a plurality of yarn beams operably associated with said frame, means to supply yarn from the yarn beams to the yarn consuming machine mounted on said frame and means to move said yarn beam support means into and out of operative relationship with said means to rotate the yarn beams, said means to support yarn beams including a pair of elongated beams pivotally mounted in said creel.
Claim 3
Dependent Claim
22 words
The creel of claim 1 wherein said elongated beams have a means attached thereto to lock each yarn beam in position thereto.
Claim 4
Dependent Claim
26 words
The creel of claim 2 wherein each of the elongated beams have a stop member mounted adjacent both ends to prevent yarn beams from rolling off.
Claim 5
Dependent Claim
33 words
The creel of claim 1 wherein said frame has a switch means to de-energize said means to rotate when said elongated beams are pivoted out of operative relationship with said means to rotate.
Claim 6
Dependent Claim
76 words
The creel of claim 1 wherein said means to supply yarn includes a pivotally mounted dancer roll means responsive to the tension of the yarn being supplied to said machine to control the speed of rotation of the yarn beams and means attached to said support means to pivot said dancer roll means upwardly out of the way when said support means are moved out of operative relationship with said means to rotate the yarn beams.
Claim 7
Dependent Claim
32 words
The creel of claim 5 wherein a means is mounted on said creel which is engaged by said dancer roll means when it is pivoted upwardly to stop said yarn consuming machine.
Claim 8
Dependent Claim
78 words
The creel of claim 1 wherein said means to supply yarn includes a means to maintain substantially constant tension on the yarn being supplied, said means to control tension including a dancer roll arrangement operably associated with the dancer roll arrangement and a linkage arrangement to vary the speed of the means to rotate the plurality of yarn beams, said linkage arrangement including a means to adjust the position of the linkage relative to the dancer roll arrangement.
Claim 9
Dependent Claim
54 words
The creel of claim 7 wherein said dancer roll arrangement includes a dancer roll support roll means and said linkage arrangement includes a lever connected to said dancer roll support roll means and rotating therewith, a slotted collar adjustably connected to said dancer roll support roll, said lever being connected to said slotted collar.
