Definitions

  • the insert substantially iills the space within the U-shaped
  • This invention relates to shuttles, and more especially to a shuttle grip and strap assembly wherein the grip includes an insert, and wherein the grip lis constructed entirely of integral members of nylon and the like.
  • Another important object of the invention is to pro vide a shuttle grip and strap assembly wherein a fastening screw can no longer cause warp breakouts.
  • Another important object of the invention is to minimize the use of fastening means, avoiding splits in the shuttle body.
  • Another important object of the invention is to minimize cracking and splitting in the relatively thin base portion of the shuttle which supports the shuttle grip and strap assembly.
  • FIGURE 1 is a perspective view illustrating a grip and strap assembly constructed in accordance with the present invention
  • FIGlU-R'E 2 is a top plan view further illustrating the assembly constructed in accordance with the present invention
  • FIGURE 3 is a transverse sectional. elevation taken on the line 3--3 in FIGURE 2,
  • FIGURE 4 is a perspective view illustrating a strap constructed in accordance with a modified form of the invention.
  • FIGUR-E 8 is a perspective view illustrating still another modiiied form of the invention.
  • the drawings illustrate a shuttle grip ⁇ and strap assembly wherein the grip, lreferred to at A, includes a substantially U-shaped shank portion.
  • An integral strap has a substantially horizontal cover portion B overlying the U-shaped shank portion.
  • An insert C is integral with said cover portion iB.
  • the cover portion and the insert are constructed of relatively rigid incompressible synthetic polymeric material having plastic set as to be capable of exerting a tight locking action upon a metallic element passing therethrough with a tight dit.
  • the insert substantially lills the space within said U-shaped shank portion so as to insure proper grip opening.
  • a fastening member 'D has an elongated shank portion passing through an intermediate portion of said insert and has a tight lit therein so that the insert lockingly grips the elongated shank portion of the fastening member.
  • Enlarged members are carried by the terminal portions of the elongated shank portion of the fastening member D securing the cover, insert and grip portions together, and positioning the assembly -within the shuttle body.
  • shock occasioned during weaving is absorbed by the insert which, also, positively retains the elongated shank portion of the fastening member.
  • the cover and the insert have a downwardly inclined wall E integral therewith.
  • An enlarged base portion is integral with the cover, insert and wall for transferring force to the shuttle body during a bobbin change operation.
  • the grip insert and base are positioned directly upon the shuttle.
  • a thickened shuttle base portion F is provided beneath the enlarged base portion.
  • FIGURES 1, 2 and 3 of the drawings a conventional shuttle body, constructed from wood or plastic, is designated by the numeral l10.
  • the shuttle body 10 has a bobbin receiving cavity 11 and an extension 12 thereof, for receiving a shuttle grip and strap assembly.
  • the bobbin receiving cavity 11 is defined in part by a marginal portion 13 which forms a relatively thin base of the shuttle body for receiving forces exerted during the bobbin change operation upon the shuttle grip and strap assembly.
  • the grip A has a substantially U-shaped shank portion 14, iiex portions 15, and tip portions 16.
  • the grip portion is normally, as here, constructed of steel.
  • the integral strap has a substantially horizontal cover portion B which overlies the U-shaped shank portion.
  • the insert C is integral with the insert cover portion B and substantially lills the shank portion 14 of the shuttle grip.
  • the fastening member D has an elongated shank portion I17 ⁇ with a head 17a at one side thereof, and a nut 17b carried by a threaded portion 17c on the other side.
  • the enlarged portions 17a and 17b, together with the shank portion 17, secure the cover, insert and grip portions together, and position same positively within the cavity 12 which receives the shuttle grip and strap assembly.
  • FIGURES 4, and 6 illustrate a modified form of the invention wherein the cover portion B has a relatively short marginal portion 19 on each side thereof so as not to extend substantially beyond the outer edges of the U-shaped shank portion. 'Ihe marginal portions 19 overlie the U-shaped shank portion.
  • the inclined wall E is substantially wider than the cover B, as is best shown in FIGURES 4 and 5.
  • the inclined wall E has a relatively broad base portion 20 positioned upon a relatively thin base portion 12 of the shuttle. This embodiment is especially adaptable to ease in the molding operation, and is constructed preferably from nylon and the like.
  • FIGURE 7 illustrates another modified form of the invention wherein, in addition to the opening 18 in the insert C, a vertical opening 21 is provided for receiving an additional fastening means D.
  • a base portion Z2 is provided for the strap which supports the spring grip A.
  • FIGURE 8 illustrates still another modified form of the invention employing a horizontal opening 18 in the insert, as Well as a vertical opening 21.
  • the horizontal opening 18 is split as by the slot 18a which permits pressure to be exerted upon the shank portion of the fastening means passing therethrough to assure an especially tight iit. This is accomplished by tightening the vertical fastening means which pass through the opening 21.
  • a grip and strap assembly for a shuttle, said grip having a substantially U-shaped shank portion; the irnprovement including: an integral strap having a substantially horizontal cover portion overlying said U-shaped shank portion; an insert integral with said cover portion; said cover portion and said insert being constructed of relatively rigid incompressible synthetic polymeric material; said insert engaging said U-shaped shank portion so as to insure proper grip opening; a downwardly inclined -wall integral with said cover and said insert constructed of relatively rigid incompressible synthetic polymeric material; a fastening member having an elongated shank portion passing through an intermediate portion of said insert; and enlarged members carried by the terminal portions of said elongated shank portion of the fastening member securing the cover, insert and grip portions together; whereby shock is absorbed by the insert which integrally retains and supports the cover and wall portion while avoiding damage to the warp and maintaining proper grip opening.
