Definitions

  • Carriers of the prior art have been comparatively expensive to fabricate and have been difficult to apply in proper alignment with the propelling member. It has been generally necessary to remove the tape and carrier to a working area where a suitable fixture could be used for positioning each carrier in relation to the carrying tape.
  • the instant invention discloses improvements in those carriers of the prior art which have been removably applied to reciprocable tapes.
  • the drawings show a carrier suitable for use in receiving or extending a filling end, but it will be understood that the disclosure would cover an inserting carrier equally well.
  • FIG. 1 is a side elevational view of a filling extending carrier
  • FIG. 2 is a plan view of that shown in FIG. 1;
  • FIG. 3 is an enlarged portion of FIG. 1 shown partially in section
  • FIG. 4 is similar to FIG. 3 with a modified fastening means
  • FIG. 5 is a forward end elevation of that shown in FIG. 1.
  • a filling extending carrier generally designated 11 is shown with a tension pad 12, a filling catching hook 13 and a forward end 14 which becomes the leading edge when the carrier is inserted into a shed.
  • the tension pad 12 is secured to the carrier 11 in any suitable manner as by flat head screws 3,272,237 Patented Sept. 13, 1966 15 and will serve to trap and pay out the filling yarn as is well understood by those familiar with this type of loom.
  • This portion of the filling extending carrier is well known and is merely to position that which is novel in this carrier by way of means for its ease of removal and proper application.
  • the carrier 11 has a generally flat trailing surface 16 which will lie in a more or less horizontal plane, parallel with the filling placing tape to which it will be secured.
  • the flat flexible tape 17 is reduced in width as at 18 and 19 (FIG. 2) to generally follow the conformation of the central portion of the carrier 11.
  • Both edges 20 and 21 of the tape 17 are curved downwardly as shown in FIGS. 2 and 5 to approximately the plane of the lower edge of the trailing surface 16. These downwardly curved edges may extend longitudinally of the tape 17 a distance in the range of three to four inches where the surface will then become flat (not shown).
  • bosses 22 and 23 On the upper side of the surface 16 are two circular bosses 22 and 23 (FIGS. 1 and 3) which are spaced apart along the longitudinal center line of the surface 16.
  • the bosses 22 and 23 are of a size to fit securely into two matching apertures longitudinally spaced upon the free end of the tape 17.
  • the free end of the tape referred to is that end to which the carrier is attached and which is 1 free to enter and to retreat from the warp shed.
  • a third aperture 24 (FIGS. 1 and 2) through the tape 17 is spaced apart from the other two apertures and is in line therewith.
  • the surface 16 narrows to an upwardly deflected trailing end 25, positioned so as to extend into the aperture 24.
  • the combination of .the positioning bosses 22 and 23 on the carrier 11 which will be encompassed by the tape apertures and the trailing end 25 which will extend into the aperture 24 will locate any replacement carrier in proper alignment without further fixtures.
  • a pressure plate 26 of flat metallic stock shaped generally to conform with the flat trailing surface 16 of the carrier 11 is placed overlying the free end of the tape 17.
  • the plate 26 has a flat central portion with two fastener holes lying directly above the bosses 22 and 23 and the apertures in the tape 17
  • a downwardly directed trailing end 27 is adapted to extend into the aperture 24 overlapping and in some pressure contact with the upwardly deflected trailing end 25.
  • a yarn protecting forward shoulder 28 which is formed as a part of the pressure plate 26 will overlap the forward edges of both the tape 17 and the carrier surface 16 (FIGS. 1 and 2).
  • the bosses 22 and 23 would have been drilled and tapped to receive set screws.
  • the fastening means is a pair of rivets 31 and 32 while other methods of fastening may also be considered.
  • this carrier may be readily applied to a tape while still upon a loom and it will be in a true setting without the need of further adjustment.
  • the carrier in such looms must be free of any snagging or projecting surfaces or points in order not to interfere with the wiping action of the warp threads as it enters or leaves the shed. This freedom from snagging is taken care of on the inward motion by the shoulder 28 which protects the edges of the tape and the carrier.
  • the downwardly curved edges 20 and 21 of the tape are such as to pass the yarn of the lower shed beneath the carrier with out damage.
  • the warp yarns of the shed will be gently separated by the curved ends 25 and 27. The yarn can in no way become caught or snagged and Warp yarn breakage is held at a minimum.
  • a filling carrier including an upwardly deflecting trailing end, at least one positioning boss formed with said carrier and adapted to be encompassed by said aperture, and fastening means whereby said carrier may be detachably secured to said filling placing member.
  • a filling carrier including an upwardly deflected trailing end, said end being positioned so as to extend into one of said apertures, at least one positioning boss formed with said carrier and adapted to be encompassed by said aperture, and fastening means whereby said carrier may be detachably secured to said filling placing member.
  • said filling placing member comprising a generally flat flexible tape, the free end of said tape having a plurality of longitudinally spaced apertures therethrough, a filling carrier including an upwardly deflected trailing end, said end being positioned so as to extend into one of said apertures, two positioning bosses formed upon said carrier in spaced relationship and adapted to be encompassed by said apertures, a pressure plate adapted to overlie said free end of said tape, and fastening means whereby said carrier and said plate may be detachably secured to said tape.
  • said pressure plate includes a generally fl-at central portion having fastener holes cooperatively spaced above said apertures.
  • said pressure plate also includes a downwardly directed trailing end, said downwardly directed end extending into said aperture overlapping and in pressure contact with said upwardly deflected trailing end.
  • a filling carrier including an upwardly deflected trailing end, said end extending into one of said apertures, at least two positioning bosses formed upon said carrier in spaced relationship and adapted to be encompassed by said apertures, a pressure plate adapted to overlie said free end of said tape, a unitary yarn protecting forward shoulder extending from said pressure plate, said pressure plate including a generally flat central portion having fastener holes cooperatively spaced above said apertures, a downwardly directed trailing end, said downwardly directed end extending into said aperture overlapping and in pressure contact with said upwardly deflected trailing end, and fastening means whereby said carrier and said plate may be detachably secured to said tape.
