Application December 8, 1943, Serial No. 513,341 '7 Claims, (01. 179-11002) 1 i The present invention relates to a winding‘ (1.?‘ vice, in guiding of» a character wire in apparatus adapted particularly inwhich ‘sound -,for is adapted to be magnetically impressed on the wire as it passes through a suitable magnet box dis posed between the wire supply and take-uh spools In the present day systems of recording sound avoiding imparting of sharp turns or bends to the wire inits travel. Suitablcdrive mechanism is incorporated with the winding device, and the drive mechanism is of a character providing for feeding the wire at the appropriate speed through the magnet‘ box on Wire, Wire of very small. diameters are. utilized, and in the known apparatus provided ‘for guiding the wire from the supply spool to the take-up SPOOL. and vice versa setting and breakage of. the wire frequently occurs- In Winding apparatus when the Wire is. passing from the supply 5.9091 to the take-up spool andthrough the recorder for recordingv sound thereon. ‘The, drive mecha with which I am familiar traversing mechanisms are provided for guiding the wire upon the supply and take-up spools to and fro thereof in the di 22 modate the plate. member and ‘the guide pulleys therebetween to provide for guiding‘ the: wire in relatively long‘ sweepsbetween the pair of spools nism incorporates the“ feature of providing-L for: a much higher speedier rewhldihs 91? the Wire titer 15 a recording has: been. made thereon i- e when the rection of ‘the axes of rotation of thespools in wire is to be transferred from the take-up spool order to wind the wire» in successive layers‘ upon to the. originalsupply spool, to be the position the spools. One of the chief difficulties with the for passing through a transcriberior transcribe prior art devices is that they incorporate unsatis ing the sound, recorded on the Wir-e‘ factory guide means for guiding the wire as it 20 > Now, in order to acquaintthose- skilled in‘ the art leaves and approaches the spools, in that they are with the manner of constructing. and. operating a of a character which cause the wire to set‘ or winding‘ device accordance» with my inven break.

It is an object of my invention to provide a winding mechanism for guiding wire from'a‘supe ply spool to a take-up spool or vice versa in which the wire is not subjectv to being set, eliminating the cause of frequent breakage. of the wire.
