Definitions

  • This invention relates to driving arrangements for spindles of textile machines of the kind wherein the driving connection between a wharle and a spindle or tube, as the case may be, is of a frictional character, such as a cone couplingor clutch having means forde-clutching same; and the invention has for its principal object to ensure, by means analogous to a clutch-stop, that when a bobbin is arrested internal friction is prevented or minimized.
  • the driving arrangements of the frictional-clutch kind for the spindles of a textile machine operating on either the ring or cap system embody means for in- 1 stantaneously arresting rotation of a bobbin in such manner as to ensure and maintain axial stability of the bobbin and thereby to preserve the normal clearance between it or a tube within it and the rotating member within its bore.
  • each spindle unit there is employed with each spindle unit an intermediate member co-operating frictionally with the wharle and adapted to drive the bobbin and means tormove said intermediate member out of contact with the wharleand into frictional contact with a stationary abutment whereby instantaneously to arrest rotation of the bobbin and at the same time to procure and maintain axiality of the bobbin and thus avoid or minimize frictional contact with the rotating member within its bore.
  • the aforesaid movement of the intermediate driving member may either be effected manually or mechanically and in the latter case it may be associated with a stop motion and actuated through the medium of a detector mechanism,
  • a tape-driven wharle is fast on and drives a spindle mounted in abearing carried by a stationary spindle rail in relation to which a ring and ring-plate are traversed in the usual manner, and the upper extremity of said wharle is constructed with a frusto-conical surface upon which there is received a frusto-conical annular intermediate driving member having at its upper end lugs or pegs to engage positively with slots in the base of the bobbin; and concentrically with and spaced slightly from said driving member there is an internally tapered annular abutment or brake member supported in a suitable manner by the stationary spindle rail or by another continuous stationary rail.
  • a movable shoe or equivalent device adapted to be actuated manually or mechanically so as to impart upward axial movement to said driving member whereby to raise its internally tapered surface out of frictional contact with the driving wharle and its externally tapered surface into frictional contact with the internally tapered annular abutment member and thereby instantaneously to stop rotation of the bobbin when that is desired; the co-acting tapered V or conical surfaces then in engagement maintaining the bore of the bobbin concentric with the spindle and out of contact therewith and the spindle continuing to rotate without any friction being generated between it and the bore of the bobbin.
  • a tube whereof the diameter of the bore is slightly in excess of that'of the spindle blade may be secured at its lower extremity to said intermediate driving member, in which case when the bobbin is arrested the spindle blade continues to rotate within said tube and without contact therewith.
  • the driving wharle is fast on a -tuberotatable in respect to the spindle blade and, in order to provide for the vertical traverse of the bobbin, the stationary abutment or brake member and the movable shoe or other actuator forthe intermediate driving member are supported by the lifter plate, said shoe or other actuator, when mechanically operated, being controlled by a stop motion through the medium of a cam whereby to enable the device to function at any point in the traverse of the bobbin.
  • Figure l is a sectional side elevation of so much of a spindle unit of a ring-spinning machine as it is necessary to show for the understanding of the invention
  • Figure 2 is a detail plan view of a stationary abutment member and its supporting means.
  • Figure 3 is a sectional plan view on the line 3-3, in Figure 1;
  • Figure 4 is a detail plan view of the means for disengaging the intermediate driving member, and
  • Figure 5 is a detail front view on line 5-5 in Figure 1 looking in the direction of the arrows.
  • Figure 6 shows the application of the inven tion to a cap-spinning machine and is a view similar to Figure 1.
  • Figure 7 is a detail front View.
  • I is a stationary spindle rail carrying a bearing 2 for a spindle 3 on which is fixed a tape-driven wharle 4, and 5 is a ring supported by the ring plate 6 adapted to be traversed in relation to the bobbin l by any usual or suitable means not shown.
  • the drive to the bobbin 'i' is of the known kind involving a disengageable friction cone clutch whereof one member engages positively with the bobbin and frictionally with the wharle, and for this purpose the wharle i is constructed with an upward frusto-conical extension 3 adapted to mate with the similarly coned interior 9 of an annular intermediate driving member Mi secured to the lower extremity of a tube i! extending the full length of the bobbin and spaced slightly from the spindle i; the member if! having at its upper end driving pegs engaging positively in the usual manner with slots in the base of the bobbin 7.
  • the lower external surface Q2 of the intermediate driving member it is of frusto-conical configuration and concentrically therewith and spaced slightly therefrom is an internally tapered annulus 93 held removably by a grub-screw M in a circularframe l integral with a stem it cast in one with an annular oiling chamber I! having a filling neck 58 and forming part of the bearing 2 of spindle ,3.
  • a bifurcated arm 2! adapted forwardly to embrace the wharle i and terminating in rounded lugs 22 the lever 2i being weighted forwardly at 2 IA and resting normally against a projection MA on stem it, with the lugs 22 clear of any running parts, while rearwardly the tail of said arm 2! is located below a resilient shoe 23 borne by a connection 26 from the trap lever (not shown) of a detector mechanism (not shown).
  • 59A is a plate for retaining the pin 5 9 in position.
  • Alternative- 1y instead of being adapted for actuation by the resilient shoe 23, the bifurcated arm 24 may be appropriately disposed for actuation manually by a machine operative when required.
  • FIG. 6 of the accompanyin drawings which illustrates one constructional em-- bodiment of the invention as applied to a capspinning machine
  • 25 is a spindle rail in which is mounted a stationary spindle 26 carrying a cap 21, and 2-13 is a tape-driven wharle secured to the lower extremity of a tube 29 extending the full height of the bobbin 3i] the wharle 28 being formed with an upwardly projecting frusto-conical extension 3! above which is seated frictionally an internallyand externally frusto-conical intermediate driving member 32 adapted to engage the bobbin 3!: by means of the usual pegand-slots conection.
  • the lifter plate 33 is the lifter plate serving to traverse the bobbin 30 in the usual manner and by means of the usual mechanism (not shown), and on said lifter plate 33 is fixed a casting as having an upwardly extending stem 35 terminating in an annular abutment member 36 whereof the inner surface is tapered correspondingly to the tapered outer surface of the driving member 32 from which the abutment member is spaced slightly.
  • the driving member 32 is formed around its lower edge with a flange 3'! below which is disposed a forked shoe 38 carried by a rod 39 pivoted at 39A to the lifter plate and whereof the curved lower extremity is connected actuatively to an operating cam in such a manner as to function through a connection 45 from an appropriate detector device (not shown) in conjunction with the roller stop motion as will be well understood; said forked shoe 38 being caused when a thread breaks to raise the member 32 into frictional contact with the abutment 3G to stop instantaneously the rotation of the bobbin 36 while the tube 29 continues to rotate therein.
  • the invention is not limited to the particular configuration of the frictionally engaging surfaces or parts described above, but is capable of variation therefrom in any desired manner that will permit the arresting instantaneously of the rotation of the bobbin by the frictional engagement of an intermediate driving member with a stationary abutment. Furthermore, the invention is not limited to the positive driving engagement between the aforesaid intermediate member and the bobbin described above, but any other appropriate driving connection may be employed.
  • Driving arrangement for spindles of textile machines including a driven wharle having an upwardly extending frusto-conical portion and a frusto-conical coupling member seating frictionally on said upwardly extending portion of said wharle and connected so as to drive positively a rotary member such as a bobbin, characterized by an internally tapered annular stationary abutment member spaced from and concentric with said coupling member, said coupling member having a similarly tapered external surface, and means to engage said couplin member frictionally with said abutment member.
