Oscillatory napping apparatus

Claim 2

IN COMBINATION WITH A NAPPER APPARATUS OF THE TYPE INCLUDING A ROTATABLE NAPPING DRUM WITH A NAPPING SURFACE THEREON FOR RECEIVING A FABRIC TO BE NAPPED OF A LESSER WIDTH THAN THE AXIAL EXTENT OF SAID NAPPING SURFACE AND MOVING FROM A FABRIC SOURCE TO SAID DRUM AND ACROSS SAID NAPPING SURFACE, AN ADJUSTABLE FABRIC OSCILLATING DEVICE DISPOSED BETWEEN THE FABRIC SOURCE AND SAID DRUM FOR ENGAGING AND SHIFTING THE FABRIC TRANSVERSELY OF THE FRBRIC LINE OF MOVEMENT TO SAID DRUM TO THEREBY PROGRESSIVELY FEED THE FABRIC DIRECTLY TO THE NAPPING SURFACE ACROSS A DESIRED AXIAL EXTENT THEREOF WHICH IS GREATER THAN THE FABRIC WIDTH WHEREBY TO DISTRIBUTE THE WEAR OF SAID NAPPING SURFACE MORE UNIFORMLY ACROSS THE AXIAL EXTENT OF THE LATTER, SAID DEVICE COMPRISING A THREADED SHAFT MOUNTED FOR ROTATION, AN AXIALLY OSCILLATING FABRIC FEED ROLLER FREELY ROTATABLY MOUNTED ON SAID SHAFT AND HAVING BOTH ROTARY AND AXIAL RECIPROCATORY MOVEMENT, A GUIDE RAIL MOUNTED PARALLEL TO AND ADJACENT SAID THREADED SHAFT, A SHIFTING CARRIAGE MOUNTED UPON SAID SHAFT AND RAIL FOR GUIDED RECIPROCATORY SLIDING MOVEMENT, SAID SHIFTING CARRIAGE HAVING ARMS ENGAGING THE OPPOSITE ENDS OF SAID ROLLER AND EMBRACING SAID SHAFT AND EFFECTING AXIAL RECIPROCATION OF SAID ROLLER UPON RECIPROCATION OF SAID SHIFT CARRIAGE, ONE OF SAID ARMS ON THE SHIFTING CARRIAGE BEING THREADELY CONNECTED TO SAID THREADED SHAFT AND EFFECTING RECIPROCATION OF SAID SHIFTING CARRIAGE UPON REVERSE ROTATIONS OF SAID THREADED SHAFT, AND MEANS CONNECTED WITH SAID THREADED SHAFT FOR REVERSELY ROTATING SAID SHAFT.

Claim 3

IN COMBINATION WITH A NAPPER APPARATUS OF THE TYPE INCLUDING A ROTATABLE NAPPING DRUM WITH A NAPPING SURFACE THEREON FOR RECEIVING A FABRIC TO BE NAPPED OF A LESSER WIDTH THAN THE AXIAL EXTENT OF SAID NAPPING SURFACE AND MOVING FROM A FABRIC SOURCE TO SAID DRUM AND ACROSS SAID NAPPING SURFACE, AN ADJUSTABLE FABRIC OSCILLATING DEVICE DISPOSED BETWEEN THE FABRIC SOURCE AND SAID DRUM FOR ENGAGING AND SHIFTING THE FABRIC TRANSVERSELY OF THE FABRIC LINE OF MOVEMENT TO SAID DRUM TO THEREBY PROGRESSIVELY FEED THE FABRIC DIRECTLY TO THE NAPPING SURFACE ACROSS A DESIRED AXIAL EXTENT THEREOF WHICH IS GREATER THAN THE FABRIC WIDTH WHEREBY TO DISTRIBUTE THE WEAR OF SAID NAPPING SURFACE MORE UNIFORMLY ACROSS THE AXIAL EXTENT OF THE LATTER, SAID DEVICE COMPRISING A ROLLER SHAFT, AN AXIALLY OSCILLATING FABRIC FEED ROLLER SUPPORTED BY SAID ROLLER SHAFT AND HAVING BOTH ROTARY AND AXIAL RECIPROCATORY MOVEMENT THEREWITH, A THREADED DRIVE SHAFT SUPPORTED IN PARALLEL AND ADJACENT RELATION TO SAID ROLLER SHAFT, A SHIFTING CARRIAGE MOUNTED UPON SAID ROLLER SHAFT AND SAID THREADED DRIVE SHAFT FOR GUIDED RECIPROCATORY MOVEMENT, SAID SHIFTING CARRIAGE HAVING ARMS ENGAGING THE OPPOSITE ENDS OF SAID ROLLER AND EMBRACING SAID ROLLER SHAFT AND EFFECTING AXIAL RECIPROCATION OF SAID ROLLER UPON RECIPROCATION OF SAID SHIFTING CARRIAGE, SAID ARMS ON THE SHIFTING CARRIAGE BEING THREADEDLY CONNECTED TO SAID THREADED DRIVE SHAFT AND EFFECTING RECIPROCATION OF SAID SHIFTING CARRIAGE UPON REVERSE ROTATIONS OF SAID THREADED DRIVE SHAFT, AND MEANS CONNECTED WITH SAID THREADED DRIVE SHAFT FOR REVERSELY ROTATING SAID THREADED DRIVE SHAFT.

Claim 4

IN COMBINATION WITH A NAPPER APPARATUS OF THE TYPE INCLUDING A ROTATABLE NAPPING DRUM WITH A NAPPING SURFACE THEREON FOR RECEIVING A FABRIC TO BE NAPPED OF A LESSER WIDTH THAN THE AXIAL EXTENT OF SAID NAPPING SURFACE AND MOVING FROM A FABRIC SOURCE TO SAID DRUM AND ACROSS SAID NAPPING SURFACE, AN ADJUSTABLE FABRIC OSCILLATING DEVICE DISPOSED BETWEEN THE FABRIC SOURCE AND SAID DRUM FOR ENGAGING AND SHIFTING THE FABRIC TRANSVERSELY OF THE FABRIC LINE OF MOVEMENT TO SAID DRUM TO THEREBY PROGRESSIVELY FEED THE FABRIC DIRECTLY TO THE NAPPING SURFACE ACROSS A DESIRED AXIAL EXTENT THEREOF WHICH IS GREATER THAN THE FABRIC WIDTH WHEREBY TO DISTRIBUTE THE WEAR OF SAID NAPPING SURFACE MORE UNIFORMLY ACROSS THE AXIAL EXTENT OF THE LATTER, SAID DEVICE COMPRISING A ROLLER SHAFT, AN AXIALLY OSCILLATING FABRIC FEED ROLLER SUPPORTED BY SAID ROLLER SHAFT AND HAVING BOTH ROTARY AND AXIAL RECIPROCATORY MOVEMENT THEREWITH, A THREADED DRIVE SHAFT SUPPORTED IN PARALLEL AND ADJACENT RELATION TO SAID ROLLER SHAFT, A SHIFTING CARRIAGE MOUNTED UPON SAID ROLLER SHAFT AND SAID THREADED DRIVE SHAFT FOR GUIDED RECIPROCATORY MOVEMENT, SAID SHIFTING CARRIAGE HAVING ARMS ENGAGING THE OPPOSITE ENDS OF SAID ROLLER AND EMBRACING SAID ROLLER SHAFT AND EFFECTING AXIAL RECIPROCATION OF SAID ROLLER UPON RECIPROCATION OF SAID SHIFTING CARRIAGE, SAID ARMS ON THE SHIFTING CARRIAGE BEING THREADEDLY CONNECTED TO SAID THREADED DRIVE SHAFT AND EFFECTING RECIPROCATION OF SAID SHIFTING CARRIAGE UPON REVERSE ROTATIONS OF SAID THREADED DRIVE SHAFT, AND MEANS CONNECTED WITH SAID THREADED DRIVE SHAFT FOR REVERSELY ROTATING SAID THREADED DRIVE SHAFT.
