Definitions

  • FIG. 2 A. KC'JHLER GILL BAR Filed May 31, 1955 FIG. 2
  • FIG. 1 A first figure.
  • the present invention relates to gill bars or taller bars for gill boxes, hackle boxes and the like.
  • the needles are fastened in the gill bars by pressfitting the needles into previously prepared bores of the gill bars.
  • they are merely soldered thereto.
  • the connection of flat needles to the needle bars is even more difiicult.
  • bores with circular cross section have been widened to bores with rectangular cross sections, and the needles have been pressed into or riveted to the gill bars.
  • fiat needles with round legs have been employed and pressed into bores in the gill bars, or flat needles have been inserted into slots and have then been soldered to the gill bars.
  • Still another object of this invention consists in the provision of a gill bar for the textile industry, which will allow a very fine needling.
  • Fig. 1 illustrates a heretofore known gill bar with pressed-in round needles.
  • Fig. 2 represents a heretofore known gill bar with soldered-in flat needles.
  • Fig. 3 is a portion of a gill bar or faller bar according to the invention with an angular groove.
  • Fig. 4 shows a fiat needle for use in connection with the element shown in Fig. 3.
  • Fig. 4a shows an angular spacer for use in connection with the base member or needle support of Fig. 3 and the needle of Fig. 4.
  • Fig. 5 is a top view of a gill bar built up with the elements of Figs. 3 and 4 in conformity with the present invention.
  • Fig. 6 represents another embodiment of a base member of a gill bar according to the invention, said base member being provided with a crank or offset portion having a continuous groove therethrough.
  • Fig. 6a shows a section of a gill bar having needles mounted therein, the needles being separated by spacer means of a thickness different from the thickness of the needles.
  • Fig. 7 shows a needle provided with shoulders for use in connection with the base member of Fig. 6.
  • Fig. 7a represents a spacer member for use in connection with the support of Fig. 6.
  • Fig. 8 is a section taken along the line 88 of Fig. 6.
  • Fig. 9 is a further embodiment of a needle bar with T-shaped needles.
  • Fig. 10 shows the sequence of the needles and spacers prior to the insertion thereof into the base member or needle support.
  • Fig. 11 represents a gill bar with needles on opposite sides without the employment of spacers.
  • Fig. 12 shows an exploded view of the needle arrangement for the gill bar of Fig. 11.
  • Fig. 13 represents a needle support composed of two profiles.
  • the new gill bars according to the present invention are characterized primarily by the employment of needle legs or neck portions provided with notches, tongues or the like which needle legs together with spacers are loosely inserted into correspondingly shaped slots of the needle support. According to the desired needling or spacing of the needles, spacers of corresponding thicknesses are employed. In this way the finest needlings of the bars can be obtained in a most simple manner because no attention need be paid to the flow of solder and because very thin spacers can be employed. Inasmuch as the needles are loosely inserted into the bars and are locked at the ends of the bars, the needling of the bars can be varied in conformity with the particular conditions to be met.
  • the gill bar according to the present invention comprises a base member or needle support 1 provided with a hook-shaped groove 1'. Needles of the type shown in Fig. 4 and spacers 5 of the type shown in Fig. 4a are inserted into the groove 1 of the needle support 1 from one end thereof. As is clearly shown in the drawing, the lower ends or neck portions of the needles 4 and spacers 5 are provided with a nose 4 and 5' respectively fitting into the hook-shaped groove 1' of the support 1. In this way, the needles and spacers cannot accidentally drop out of the needle support 1. Fig.
  • FIG. 5 shows a top view of a gill ba with needles 4 and spacers 5 and the needle support 1.
  • Fig. 6 shows another embodiment of a needle support 1a which has an offset or cranked portion.
  • the groove l'a is in contrast to the groove 1' of Fig. 3 not hookshaped but straight passing all the way through. In other words the groove 1a is open at the top and bottom.
  • the needles 9 pertaining to the support 1a are of the type shown in Fig. 7, the peek portions of which are provided with shoulders 9' and 9 to prevent the needles from displacement in axial direction, i.e. upwardly and downwardly.
  • the needles of the type of the a needle 9 are spaced from each other by spacers of the type shown in Fig; 7awhich spacersar'e' provided with hould 1 a 0" ser g h sam Pur a t shoulders 9' and 9 of the needles 9.
  • 'Fig. 8 shows a section taken along the line 8 8 of Fig.
  • Fig. 6a shows in perspective a section of a gill bar 1a having needles9a mounted in the groove, the needles being separated by spacer means 10a of a thickness relativelydifferent from that of the needles.
  • needle support 1b is again provided with a straight slot extending all the way through from the top to the bottom, and the heads 11 of the needles rest against the lower surface of the needle support 1b.
  • the slide 13 may be made of spring steel sheet metal and bent'accordingly or may be milled from asolid piece.
  • the needle bar shown in Fig. 11 isequipp'ed with needles 14 protruding from the top and bottom surface .of the support 10.
  • the arrangement is such that alter- 7 bar according to the invention which is not milled out of a solid piece but is composed of two milled or drawn profiles or structural members 15 and 1'6.
  • the profiles 15, 16 are spaced from each other by a spacer member 17 inserted therebetween at each end of said profile members 15, 16 as shown in Fig. 13.
  • the spacer members 17 are, of course, in conformity with the respective desired groove shape.
  • extension 19 which may be out prior or after the elements 15, 16 and 17 have been assembled to form a needle support.
  • the extension 19 is engaged in customary mannerby hold- 7 ing members (not shown) for holding the bar. 7
  • This construction yields a further reduction in thecost of production of gill bars and is suitable for any of the above mentioned needle forms.
  • the spacer members 17 may be omitted if the lowerportion of the members 16 and 15 engage each other along a surface as indicated in Fig. Shy the feferehcenumeralifl.
  • the insertion of the neck portions of the needles and spacers into the needle support can be efiected by insert- 7 ing the same individually or by means of a device by which they are assembled in the desired arrangement 7 and are then'as a unit inserted into the respective groove.
  • the needles and spacers are displaced in the direction toward said loosened end member to such an extent that the brokenneedle or needles can be rotated by 90 degrees so thatthe broken needle or needles'ca'n be removed.
  • the broken; needle or needles are then replaced in a reverse operation, i.e. the new needles are inserted into the groove with their flat surface extending in longitudinal direction TOf the groove and are then rotated by 90 degrees to. anchor the same.
  • the needles and spacers are pushed togethcr again and are secured in their respective positions by again fastening the end piece.
  • the spacing oftheneedles can any time be variedin the shop .by inserting spacers of dilferent thicknesses.
  • neediesand spacers may be made of difierent materials.
  • the spacers it is possible to make the spacers of any synthetic material which .will retain apermanent shape, i.e. is-not elastic.
