Definitions

  • This invention relates to shuttles for looms and, more particularly to the metallic points or tips thereof.
  • the usual shuttle consists of a wooden body the end of which is provided with a metallic tip in order to protect the wooden body and to avoid rapid wear resulting from impacts.
  • the metallic tip is preferably of steel wth a tempered point.
  • the interface between the wooden body and the metallic tip is in a plane substantially normal to the longitudinal axis of the shuttle. Since the apex angle of the generally conical tip is relatively small, the boundary edge thereof at the interface is sharp. As a result, wear of the wooden body at the interface presents a crack which, even although microscopic in size, results in damage to the warp threads, particularly if they are of delicate material such as synthetics of capillary size.
  • a shuttle in which the cement between the metallic point and the rubber ring has become loose, is no longer completely free from faults and must be completely rebuilt because of the damage it will do to warp threads, particularly if they are of synthetic resin, artificial silk, and/ or of capillary size.
  • the edge of the contact surfaces can be in a direction other than parallel to the direction of the warp threads. In such a construction it is not necessary to use an intermediate layer. However, it is important where the contact surfaces are angularly related to the direction of extent of the warp threads that the peripheral edges of the metal point at the interface, be beveled.
  • FIGURE 1 shows a portion of a shuttle equipped with a point and an intermediate ring
  • FIGURE 2 is a detail perspective view of a shuttle point embodying the invention
  • FIGURE 3 is an enlarged side view of the shuttle point of this invention.
  • FIG- URE l identifies the end portion of the wooden body of a shuttle.
  • a metallic point 2 is attached to body portion 1.
  • FIGURE 2 and FIGURE 3 show the point detached and from this it is seen to consist of a unitary item having a nose of generally conical or beehive form as indicated at 6, and a flat base 5 in a plane normal to the axis of the conical nose which is also considered as the longitudinal axis of the shuttle.
  • a shank 9 of generally cylindrical form extends from base 5 coaxially thereof and fits and is secured in any suitable way, within an axial hole in the wooden body of the shuttle.
  • the edge otherwise formed between the generally conical tip or nose of the point and base 5, is beveled at 4 to form a frusto-conical rim making an obtuse angle or at 4a.
  • the peripheral edge 4 is continuous and beveled at an angle to the axis 10, each point of the beveled or frusto-conical surface lying in a respective one of a plurality of lines intersecting said axis at an angle B of the order of 45 degrees.
  • the generally circular groove or channel thus formed in the assembled shuttle, at the periphery of the interfaces between shuttle body 1 and point 2 is filled with a ring or band 3 of material as previously described.
  • the surface of the shuttle point has been described as generally conical it will be understood that this if for convenience of description and that the surface is preferably that formed, for example, by rotating the arc of a circle extending from its point of intersection with a chord, about the chord as an axis or, in other words, the surface is preferably of beehive shape.
  • a shuttle for looms comprising a non-metallic body portion having a central longitudinal axis and a forwardlyfacing end surface, a generally conical metallic point attached thereto and having a rearwardly-faeing base surface in contact with said end surface, and means securing said surfaces in contacting relation to form a shuttle assembly having a smooth regular contour, the peripheral edge of said rearwardly-facing base surface being beveled at an angle to said central longitudinal axis.
  • said beveled surface defining an outwardly-facing channel between said body portion and metallic point, and the means securing said surfaces comprising a continuous ring of vulcanized rubber fitting and secured Within said channel and forming with said body portion and point a fair smooth and continuous shuttle surface.
  • a metallic point for a shuttle for looms comprising a nose portion having a generally conical surface symmetrical about a central longitudinal axis and a base surface intersecting said axis, the peripheral edge formed by the intersection of said base surface and said generally conical surface being beveled in a frusto-conical surface at an angle to said longitudinal axis.
  • a shuttle point comprising a metallic substantially conical nose portion having a central longitudinal axis fixed with said base surface and extending rearwardly therefrom along said axis.
