Definitions

  • the invention concerns textile machinery and relates to a suction device of particular, though not exclusive, application to ring spinning frames.
  • suction tubes for drawing off broken ends from the front roller of the drafting arrangement of ring spinning frames are fixed in such a Way that the W ends of each tube are provided with attachment means working in conjunction with corresponding fixing devices rigidly secured to the machine.
  • a so-called link-spring suspension or a pivoting arm system may be used for this purpose, but in these and other assemblies a common feature is that, at least, two supports are required. Thus, for each suction tube, two fixing devices or connections are always necessary.
  • Such fixing devices not only take up a relatively large amount of room, but possess the disadvantage, particularly when in use, that both the fixing devices have to be operated simultaneously, so that the operative has, of necessity, to hold the suction tube aligned roughly parallel to the front roller by hand, and must execute a parallel movement of the suction tube when pivoting it to and from the front roller. Any slight carelessness by the operative when using the suction tube may result in the non-alignment of the tube and front roller, the elfect of such non-alignment of the tube and front roller being a suction which is not uniform over the full extent of the tube.
  • suction tube may be secured to fixed parts whether parts of the machine or components of the suction equipment, which will be economical of space but which will, in addition, ensure the true parallel alignment of the suction tube and the front roller in all positions of the one relative to the other and particularly in the extreme position adjacent the said roller.
  • a suction device of particular, though not exclusive, application to ring spinning frames includes a suction tube and a rigid arm substantially transversely thereof adapted to apply a reduced pressure to said suction tube and so pivotally mounted in a fixed support as to be capable of motion in a given plane substantially transversely of the axis of said suction tube, the means for applying a reduced pressure to the suction tube being such that the seal between said means and a fixed part of the suction assembly remains effective throughout pivoted motion of the arms.
  • the suction device is adapted to allow of the location thereof in any one of a plurality of predetermined positions relative to a fixed axis parallel to the longitudinal axis of the suction tube.
  • the rigid arm itself forms a means whereby a reduced pressure may be applied to the suction tube, said arm being so connected to the fixed suction assembly as to remain in sealed connection therewith upon pivotal motion of the arm.
  • a variant of the invention provides for such a hinged joint as to ensure that when the arm is pivoted, the suc- 2 its construction is simplified, as this arm new acts at the same time as a method of fixing in the form of a pivoting arm.
  • the joint provides freedom of movement only in one plane, the suction tube cannot deviate from parallism to the front roller in any position in which it is pivoted, except to a. very slight extent due to the play in the joint, which must be minimized; the construction of the tube itself is sufiiciently rigid to prevent substantial deviations.
  • FIG. 1 is a side elevation of one embodiment of the present invention
  • FIG. 2 is a plan View along the arrow II in FIG. 1;
  • FIG. 3 is a side elevation of an alternative embodiment
  • FIG. 4 is a plan view of the embodiment shown in FIG. 3.
  • a suction tube 1 of known type, and provided in known manner with suction ports 2, is adapted to be pivoted into position adjacent the front roller of a drafting arrangement (see FIG. 3).
  • an air conducting tube 4 is secured centrally of the suction tube 1, the other end being supported by a collar 5 disposed thereabout and having two parallel arms 6 pivotally mounted by means of pin 7 in a suitable support secured to the suction duct 8.
  • the support may be in the form of a hollow bracket 9, said pin 7 extending from the sides thereof to form projections which engage the through holes in the ends of the arms 6 thereby to pivotally support the tube 4. .
  • the arms 6 may be resilient in order that the hinged joint can easily be disconnected.
  • the hollow bracket 9 is sealed to the suction duct 8 and the wall of the latter has provided therein an opening 10.
  • the end of the tube 4 is flexibly connected to the hollow bracket 9, to the suction duct 8 or to the opening 10 therein by such as rubber sleeves or other appropriate means.
  • This particular arrangement is such that the assembly formed by the suction tube 1 and the tube 4 may be pivoted about the pin 7 whilst maintaining sealing contact between the suction duct 8 and said tube 4.
  • the motion of the tube 4 is in plane 11 (FIG.
  • the extreme position of the suction tube may be determined by co-operating elements on the bracket 9 and the arms 6.
  • a spring-loaded latch 12 fixed to each of the arms 6 may engage corresponding notched rack arrangements associated with the bracket 9.
  • a tilting spring arrangement with adjustable end stops may be used, the adjustable end stops allowing of an alteration in extent of pivotal motion of the tube 4 and thus the spacing of the suction ports 2 from the front roller or from the pin running therefrom.
  • the suction duct 8 is, of course, the large suction duct, which usually runs for the whole length of the machine and is connected to an exhauster, a filter, or the like. Over the whole length of the machine, of course, several art.
  • the hollow bracket 9 can be connected to the wall of the suction duct via a sealing washer Orrubber washer 13, and then, of.course,.this sealing washermust be appropriately cut out in the middle.
  • connection between the swivelling arm 4 and the suction duct 8 may be so arranged that the connection isbetween the hollow bracket'9 'andthe pivoting arm 401' between the latter and the opening'ltlw.
  • FIGSJB and 4 show an alternative embodiment.
  • the. outside edge 21 of the suction tubel would, on pivotal motion in the tube '4 round theaxis7, carry out a movement corresponding to the curve 22; the edge 21, therefore, follows the curve "To overcome this difi'iculty, flthepivo'ting and not 'fixe'd,"'but isarranged so that it can be moved by fittinga sealing but flexible connection 25 between the suction duct "Son the one hand and'the end 4 of the pivoting tube 4; so that such a pivoting motion of the pivoting tube 4 is effected, that is to say, a motion in which .theedgejZl follqws the curve 26, .guidesare proyided,su'c h ,that upon pivoting tube 4 in'a downward direction, a displacement offthe' tube in ,the direction of the arrowfIValsooccurs,

  • a suction device as claimed in claim 1 including cooperating means on the arm and on the fixed support whereby the suction tube may be located in any one of a plurality of predetermined angular positions about the pivot of said rigid arm.
  • suction device for a plurality of threads all moving in substantially the same plane on a spinning frame comprising in combination, a hollow suction tube parallel to the plane of the threads and having a plurality of transverse apertures defined therein each of which communicates with the hollow interior of said tube and with said apertures beingv longitudinally spaced along said tubes so suction tube and having its hollow interior communicating with the hollow interior of said suction tube, a suction duct defining an aperture therein, substantially airtight flexible sealingmeans connecting said rigid tube at the end thereof which is remote from said suction tube with said aperture defined in said suction duct, and means mechanically coupledjbetween said rigid tube adjacent its said remote end ,and said duct and permitting rotation of said rigid tube only about an axis which is parallel to said suction tube, whereby rotation of said rigid tube causes said "suction tube to always remain parallel to the plane of a thread .4.
