Definitions

  • Another object of the invention is to provide an improved clamp-washer which may be used on any of the individual sewing machines of a particular class, thereby eliminating the need for selecting a clamp-washer that will work best with a particular sewing machine.
  • the sleeve 24, which is secured tothe main shaft 18 by means of a tapered pin 31, is provided at one end with a flange 32, one annular shoulder or surface of which is designated by the numeral 33.
  • the other end of the sleeve 24 has an end surface 34 and an internally threaded bore 36, the surface 34 being interrupted by a pair of diametricallyrecess 47 having an annular clutch surface or seat 48,
  • the hand wheel 126 is formed with an annular end face 146, which abuts the aforementioned annular surface 133.
  • the outer face of the hand wheel 126 is provided with a collar 147 having an annular clutch face 148, the face 148 being adapted to be contacted by portions of a clamp-washer 149, presently to be described.
  • a clutch screw 151 having an externally threaded shank 152 and an internally facing annular clutch surface 154 is screwed into the threaded bore 136.
  • the screw 151 has a removable stop pin 156 and a knurled rim 157 of known construction.
  • the front or outer face 159 of the clamp-washer 149 has three outwardly struck lugs 161-161-161, each lug having an outwardly facing surface 162 designed to engage the clutch surface 154.
  • the inner surface 169' of the Washer 149 has three struck.
  • lugs 171-171-171 each providing an infacing surface 172 arranged to engage the annular clutch face 148. This arrangement of lugs provides a washer 149 which could be said to be corrugated.
