Definitions

  • ABSTRACT A flyer has a unitary frame that is cast of a light alloy metal and includes a pair of legs joined at their upper ends by a connecting and supporting arch and a lower annular member to which the legs are securely joined at their lower extremities to form a closed loop.
  • the frame also includes at least one rigid tubular member in the arch that extends downwardly through the legs and is embedded in the lower member.
  • a press-finger is mounted on one of the legs with the tubular member of that leg being a guiding tube for the sliver.
  • Such compound frame-type flyers further have the great drawback that they are only reasonably stable in the form of a frame, but are not distortion-proof, so that if a leg gets broken by impact, for instance, the high centrifugal force causes them to break asunder at the joints. Moreover, these known flyers are expensive to manufacture and, being prone to damage, are there fore uneconomical in use.
  • FIG. 1 shows, partly in section, a flyer as viewed from the broad side
  • FIG. 2 shows the flyer according to FIG. 1 turned through 90
  • FIG. 3 shows a section through a long leg along line Ill-III of FIG. 1 on a larger scale, with the press-finger bearing also shown.
  • the flyer shown in FIGS. 1 and 2 comprises a flyer frame 1 consisting of a single piece closed upon itself in the form of a loop by having two legs 3 and 5 which are interconnected at the upper end by a strong connecting arch 7, at the lower end by a distortion-proof annular connecting piece 8.
  • the high strength of the connecting piece 8 is achieved in that the piece consists of a ring 8a, with a tubular neck 9 and an upper terminal flange 10.
  • the upper end of the flyer is further provided with a balancing disk 12 to which, as also to the lower connecting piece 8, balance correction pieces 15 can be attached.
  • a press-finger 14 Pivoted to one of the legs 3 by means of bearing 24 is a press-finger 14, with a press-finger counterweight 26 forming the connection between the two bearings and the actual press-finger 14.
  • the flyer presents a rotational axis 16.
  • the flyer frame includes a guide tube 18 and a reinforcement tube 20 of steel or some other metal that is cast integrally with the frame within the legs 3 and 5 respectively, the connecting arch 7 and the lower connecting piece 8.
  • the flyer is driven and supported at the lower connecting piece 8 by a driver (not shown).
  • the guide tube 18 made of steel or some other metal, guides the sliver (not shown), which issues through a bore 13 at the level of the press-finger.
  • the two tubes 18 and 20 form reinforcements for the outer flyer portion, made of cast light alloy. These tubes are concurrently intended to permit a lighter casting of high strength to be made.
  • This reinforced frame construction gives the flyer very high stability, strength and breaking resistance. As the legs of this flyer, unlike the conventional type, are held together below, the expansion due to the centrifugal force can be reduced despite the double flyer height necessary.
  • the flyer described can be cast of a piece from commercial light-alloys, and this not only reduces the manufacturing cost below that of known flyer types, but also ensures a higher distortion resistance.
  • the press-finger can be made in such a way that its centrifugal force acts not on the middle of the leg, but rather on the upper and lower ends of the pressfinger bar, so that in this respect again the leg is exposed to a lower fatigue load and stress than is the case in the known flyers of the closed-ended type.
  • this flyer can be given a favourable aerodynamic design.
  • the casting process also permits the favourable press-finger bearing shown to be made in the space inside the streamlined casing 11, with the two bearing supports 24 extending through two openings in the said casing.
  • This type of press-finger bearing permits the press-finger counterweight 26 to be arranged in the lee of the leg, without any adverse effect on the pressfinger pressure conditions between initial and end positions.
  • this arrangement not only saves space, but also provides better equilibrium conditions in the extreme press-finger positions and prevents undesirable aerodynamic effects from neighbouring flyers on the press-finger pressure.
  • a flyer comprising:
  • a flyer according to claim 1 wherein said lower annular member comprises a lower ring, a tubular neck and an upper terminal flange, an outer extremity of diametrically opposed edges of said ring and said flange being joined to said legs and at least one tubular member for providing support to said frame legs.
  • each frame leg includes an outwardly extending projection for streamlining of the respective legs, and wherein:
