458,244. Removing waste yarns from bobbins. POLLAK, J. E., 20, Holborn, London.-(Stutz & Cie Vorm. J. Stutz-M³ller ; Kempten, Switzerland) July 16, 1936, No. 19785. [Class 120 (iii)] A machine for removing waste yarn from bobbins has reciprocating push members which eject the bobbins between stripping members alternately at either end of the machine. On the frame 1 of the machine is a crank-shaft 3 in bearings 2 and co-operating with a crank strap 4, 5, 6 to which horizontal push rods 7 mounted in bearings 8 are secured. At each end of the shaft 3 is a disc 9 with a cam groove 10 to receive studs 11 on lever arms 12. Each lever arm 12 is fixed to a shaft 13 to which an oscillating movement is imparted by rotation of the grooved discs 9. Exteriorly on each shaft 13 are fixed two arms 14 which coact bv means of rods 16 with push rods 15. Compression springs 18 tend to separate the arms 14, 15. Each push arm 15 has a slot 19 receiving a pin 20 of a correlated push rod 21. The rods 21 are mounted in bearings 22 and carry at their ends the stripping members-one narrow pair 23 and another pair 24 wider than the waste yarn wrapping 26, Fig. 4. Each implement 24 has a central groove 241 and grooves 24<11> on its inner surface. Beyond the stripping elements pairs of brushes 27 are arranged to remove waste yarn residues. Above the frame 1 feed channels are arranged. Thus, bobbins for each end of the machine may be fed to the centre thereof. They slide automatically into the horizontal position for ejection or hammers may be provided to move the lowermost bobbin into position. The bobbins are ejected by the push members. 7 while simultaneously the stripping elements 23, 24 are resiliently urged towards the bobbin 25.
