Definitions

  • a textile machine has a structure for optionally providing an elastic or rigid mounting for a spindle-bearing housing.
  • a spindle rail is formed with an opening passing therethrough, and a spindle-bearing housing extends with clearance through this opening and carries a shoulder-ring or flange.
  • a support means engages the flange to support the spindle-bearing housing on the spindle rail and has at least a single elastic part and at least a single rigid part.
  • the support means normally assumes a position where the elastic part thereof provides an elastic support for the spindle-bearing housing.
  • a fixing means is displaceable between a fixing and a non-fixing position and, when in its non-fixing position, permits the elastic part to provide the elastic mounting for the housing. However, when the fixing means is in its fixing position it fixedly connects the rigid part of the support means to the spindle rail to eliminate the action of the elastic part of the support means.
  • the present invention relates to textile machines.
  • the present invention relates to spinning and twisting machines, and more specifically to structure for mounting a spindle-bearing housing on a spindle rail of such a machine.
  • the spindle-bearing housing is supported by a support means which has an elastic part and a rigid part and which normally assumes a position where the elastic part provides an elastic support for the housing.
  • a fixing means is displaceable between fixing and non-fixing positions. In the non-fixing position of the fixing means, the support means supports the spindle-bearing housing by way of the elastic part.
  • the fixing means when the fixing means is displaced to its its fixing position it provides a rigid fixing of the rigid part of the support means with respect to the spindle rail so as to eliminate the influence of the elastic part of the support means.
  • FIG. 1 is a partially sectioned elevation of one possible embodiment of a structure of the invention, shown in its position on a spindle rail, providing an elastic support for a spindle-bearing housing;
  • FIG. 2 shows the structure of FIG. 1, providing a fixed support for the spindle-bearing housing
  • FIG. 3 is a partially sectioned elevation showing another embodiment of the invention, providing a fixed support for the spindle-bearing housing.
  • FIG. 1 there is illustrated therein a spindle rail 1 which is formed with an opening 2 passing therethrough. It is to be understood that such openings 2 are distributed all along the spindle rail 1, as is well known.
  • a spindle-bearing housing 3 extends with clearance through each opening 2, as is conventional, and the spindle structure carried by the housing 3 as well as the structure for rotating the spindle are conventional and are, therefore, neither illustrated nor described.
  • the spindle-bearing housing 3 fixedly carries a shoulderring or flange 4.
  • the lower portion of the housing 3 has an exterior thread all the way up to the flange 4.
  • a support means coacts with the shoulder 4 to support the housing 3 on the rail 1, and this support means includes an inner rigid component 5 in the form of a ring surrounding the housing 3 and engaging the flange 4 in the manner shown in FIG. 1.
  • the support means includes further an elastic intermediate ring 8 fixed to and surrounding the rigid component 5 of the support means.
  • the support means includes a third or outer ring 6 surrounding and carrying the elastic intermediate ring 8. Suitable bolts 7 maintain the outer ring 6 of the support means permanently fixed to the rail 1.
  • a nut 9 is carried by the exterior thread of the spindlebearing housing 3 and has a tubular extension 10 also threaded on the housing 3 and adapted to be pressed against the underside of the inner rigid component 5 which, in turn, presses against the flange 4, thus holding the support means against the flange 4 and housing 3.
  • the elastic intermediate ring 8 of the support means provides an elastic support for the housing 3.
  • the component 5 defines together with the spindle rail 1 a gap 11. This gap ensures a required degree of movability of the housing 3 with respect to the rail 1.
  • a fixing means 12 is actuated.
  • This fixing means is shown in its non-fixing position in FIG. 1 where it is a distance away below the rail 1. It takes the form of a nut 12 which is threaded on the extension 10 of the nut 9. When the nut 12 is displaced to its fixing position it is only threaded upwardly along the extension 10 to press against the underside of the rail 1 where it is tightened, which causes the elastic ring 8 to be deformed and the component 5 to be drawn downwardly against the rail 1 to the position shown in FIG. 2. It will be noted that the gap 11 has been eliminated.
  • the support means will again assume its normal position where the elastic ring 8 provides an elastic mounting for the housing.
  • the elastic ring 8 provides an elastic mounting for the housing.
  • the fixing means of this embodiment includes, in addition to a nut 12', a ring 14 freely movable along an extension 10 of a nut 9' and having a slotted upper portion 15.
  • the latter is provided with a series of slits or notches extending downwardly from the top surface of the ring 14 to provide the latter between its slits or notches with a plurality of springy tongues capable of being wedged between the tapered portion 13 of the component 5' and the surface of the rail 1'.
  • the nut 12' When in the case of the embodiment of FIG. 3 an elastic mounting for the housing is required, the nut 12' is displaced to a position corresponding to that of FIG. 1, where it is retracted to its lower position, permitting the ring '14 to be displaced below the tapered portion 13 so all that the support at this time is provided by way of the elastic ring 8'.
  • a spindle rail formed with an opening passing therethrough, a spindle-bearing housing extending through said spindle rail opening with clearance and fixedly carrying a supporting flange, support means engaging said flange to support said housing on said rail, said support means having an elastic part and a rigid part and normally assuming a position where said elastic part elastically supports said housing, said support means including an outer rigid component being fixed to said spindle rail, and fixing means adapted to move with respect to said support means between a fixing and a nonfixing position, said fixing means when in said fixing position coacting with said rigid part for fixing said rigid part with respect to said spindle rail to eliminate the influence of said elastic part while when Said fixing means is in said non-fixing position said support means assumes its normal position where said elastic part provides an elastic support for said housing.
  • said support means includes further an inner rigid component engaging said flange of said housing and an intermediate elastic component surrounding said inner component, said outer rigid component surrounds said intermediate elastic component, and a nut is carried by said housing and maintains said inner rigid component fixed against said flange.
  • said inner component has an exterior tapered surface extending with clearance into said opening of said spindle rail, said nut having an exteriorly threaded surface
  • said fixing means including a second nut engaging the threaded surface of said first nut, a slotted ring being adapted to be displaced by said second nut toward and away from said tapered surface of said inner component, said second nut, when the latter is in its non-fixing position, displacing said slotted ring away from said tapered surface of said inner component so that said elastic intermediate component supports said housing, and said second nut, When in its fixing position, pressing said slotted ring between said tapered surface and said spindle rail for fixing said inner component of said support means to said rail without deforming said elastic component.
