Definitions

  • a shuttle box means for checking a shuttle comprising a rigid base, a resilient sponge-like element, an elongated rigid member floatingly supported by the resilient element and a frictional covering member encompassing the rigid member and the resilient means.
  • This invention in general, relates to improvements in shuttle boxes for looms and more particularly relates to improvements in shuttle checking means to bring the shuttle to a gradual but certain stop without damaging the shuttle.
  • Conventional looms employ at least one shuttle box at each end of a reciprocating lay across which a shuttle is propelled at a very high velocity during the Weaving process.
  • the box is usually equipped with one or more walls that are covered with a friction material such as leather.
  • a friction material such as leather.
  • One or more of these walls are usually resiliently supported and the walls are cammed apart by the shuttle, which is wider than the space between the walls. The friction material thus exerts a braking force on the sides of the shuttle to check or stop its travel gradually but surely without damaging the shuttle or sloughing-off the filling.
  • Another object of the invention is to provide a shuttle box equipped with a binder covered with a resilient material for checking the flight of the shuttle Without distorting or bowing the shuttle.
  • Yet another object of the invention is to provide a 3,403,708 Patented Oct 1, 1968 shuttle box equipped with a box front covered with aresilient material for checking the flight of the shuttle without distorting or bowing the shuttle.
  • FIGURE A illustrates the prior art shuttle box and shows the'deformation or bowing of the shuttle caused by such prior art shuttle boxes.
  • FIGURE 1 is a diagrammatic plan view of the box 0 the drive end or right hand side of the loom embodiying the invention.
  • FIGURE 2 is a sectional view of the box taken on line 22 of FIGURE 1.
  • FIGURE A illustrates diagrammatically the shuttle box of the Kronoff patent, supra, and the bowing of the shuttle caused by its checking device.
  • the pressure exerted by the resilient material R on the shuttle S through the friction material F is uniform for a given degree of compression.
  • the force exerted by resilient means 'M on the thick portions A will not distort these portions due to the rigidity of these portions.
  • the walls W are too thin to compress the resilient material R to the same degree that portions A do and the Walls bow inwardly as seen in the Prior Art Figure.
  • the invention overcomes this defect of the Kronoff shuttle box by providing a rigid member between the resilient material and the friction material to transmit the force exerted by the resilient material along a line that is substanially parallel to the centerline of the shuttle when the shuttle is properly boxed. This insures that a distorting force will not be applied to the thin shuttle walls.
  • FIGURE 1 shows diagrammatically a shuttle box 10 having a binder 12 and a box front 14 which are covered in accordance with the invention. Further details of the means for supporting the binder are shown in the Kronoff patent, supra, which is incorporated herein for such known structure. Since the present invention is not limited to any specific means for supporting the binders and box fronts it would be useless to go into such mechanisms in greater detail.
  • binder 12 is supported by pivoted linkages 13, 13'. These linkages pivotally support the binder by means of pivots 16, 16'. The other ends of the linkages are pivotally supported by pivots 18, 18 on the box frame 19. It will be readily apparent to those skilled in the art that friction generated between the binder surface 26 and the shuttle S will cause the binder to exert additional pressure on the shuttle as it moves into the box and less as it moves out of the box during picking due to the pivoted supporting arrangement of linkages 13, 13.
  • box front 14 is adjustably mounted on the box frame 19 by means of the usual screws 15, 15' to permit adjustment of the shuttle box for different shuttles.
  • the binder and the box front shown in FIGURES 1 and 2 may be covered with a resilient material to assist in checking the flight of the shuttle. Since this covering is the same, whether on the binder or the box front it will be described in detail with reference to the binder with similar parts of the box front being identified by the same reference characters with primes added.
  • Binder 12 comprises an elongated rigid body 20, a
  • an elongated rigid member 24 which is floatingly supported by the resilient material.
  • a layer of resilient material 22 abutting one surface of the body, an elongated rigid member 24 which is floatingly supported by the resilient material.
  • the floating arrangement of member 24 permits it to move longitudinally relatively to body 20 but more importantly, does not permit member 24 to exert any force on its own as would be the case if member 24 was fixed to said body at one end in a cantilever fashion.
  • Layer 22 may comprise any resilient material, such as foam rubber, natural or synthetic, that is capable of expanding to its original thickness after being compressed.
  • Other resilient materials such as that shown in the Kronoff patent may be used instead of a foamed material, the particular form and composition of this layer not being critical and one skilled in the art may readily select any ma-* terial which possesses the requisite resiliency.
  • Layer 24 may be formed of any rigid material such as metals, wood, plastics, and the like, with requisite rigidity to distribute the forces exerted by the resilient material along a line that is substantially parallel to the centerline of the shuttle when it is properly boxed, thereby avoiding the exertion of undue force on the thin walls of the shuttle.
  • Aluminum has been found to possess the necessary rigidity and has the added advantage of being very light in weight.
  • Friction material 26 may comprise a leather strip or a strip of any other flexible material with the requisite strength and friction characteristics and can be readily selected from available materials by the artisan.
  • Layer 22 may be bonded to body 20 and to rigid member 24 if desired to facilitate assembly but this is not necessary to the operation of the binder.
  • a shuttle box for looms having means for checking the shuttle, said means comprising:
  • frictional means encompassing said rigid member, said resilient means, and a portion of said body whereby said frictional means adjacent said shuttle is substantially parallel to the centerline of said shuttle when said shuttle is in saidbox.
  • said resilient means comprises the binder and the box front.
  • resilient means is an elastomeric material.
