Definitions

  • This invention relates to an idler mechanism for spinning machine spindles, and more particularly to an idler mechanism which permits a spindle to be stopped during operation of the machine without presenting an increased drag on the driving belt or interfering with the proper operation of the other spindles where several spindles are driven by a common belt.
  • An object of the present invention is to provide means for selectively stopping the spindles on a spinning machine to effect repairs to broken yarns or the like without causing the driving belt to be heated up by virtue of such stoppage.
  • Another object is to provide means for selectively removing a spindle whorl from operative contact with the driving belt so that the spindle may be stopped for splic ing a broken yarn or the like without disturbing the operation of the other spindles.
  • a further object is to provide an idler means for each spindle on a spinning machine which can be selectively operated to remove the driving belt from operative contact with such spindle without disturbing the alignment of the belt with the other spindles or the driving cylinder.
  • An additional object of the present invention is to provide the combination of. a spinning machine driving belt of a thermoplastic material affording remarkably improved operational performance, in conjunction with a friction-free type of idler'means for permitting such belt to continue proper operation of a spinning frame without deleterious effects, while one or more of the spindles thereon are stopped for repairs, such as a broken yarn or the like.
  • Fig. l is aplan viewof one type of spinning frame employing the present invention.
  • Fig. 2 is a plan view of one spindle unit
  • Fig. 3 is an elevation of a single spindle unit
  • Fig. 4 is a partially sectionalized elevation of a spindle unit taken along the line 4-4 of Fig. 2;
  • Fig. 5 is an elevation of aportion of another embodiment of a spindle unit
  • Fig. 6 is an elevation of a spindle unit including a braking means
  • Fig. 7 is a plan view of the apparatus of Fig. 6;
  • Fig. 8 is a plan view of the apparatus of Figs. 6 and 7 shown in 'a shifted position. I
  • FIG. 4 one embodiment of the presentiinvention is shown as assembled on a standard spindle unit.
  • Base plate 10 is rotatably aflixed to the spindle support 3 ing frame 11 by'the spindle bottom journal 12, which is disposed through the central hole 13 of the base plate and is held by the usual journal support 14.
  • a whorl or driving pulley 17 Formed integrally with the spindle 15 at a portion thereof adjacent the upper surface 16 of the base. plate 10, is a whorl or driving pulley 17.
  • An idler means or pulley 18 is rotatably mounted'on the base plate 19 and is radially disposed thereon adjacent to the. driving pulley 17 so that the respectivev belt-engaging portions 19, 2d of both pulleys are in substantial alignment as shown.
  • any conventional type of mount can be used for the idler pulley 18, such as the stepped shaft 21 shown which is attached in a vertical position to the base plate. inany suitable fashion, or can. be formed integrally therewith.
  • the idler pulley 18. is rotatably secured to the. shaft 21 by the screw and washerrneans 22 connected to. the upper end thereof.
  • a spring, means 23 comprised of a leaf spring 24 which biases ball bearing 25, located in a hole ,26 extending through the base plate 10, against the supporting frame 11 and into either of two angularly displaced holes 27a, 27b in the latter whenever brought into register therewith by rotation or swinging of the baseplate 10 (see also Fig. 2).
  • a shifting means or handle 28 is aiiixed to the upper surface 16 of the base plate. 10 to provide means for swinging said plate relative to, the supporting frame 11 (.see also Fig. 3).
  • a brake meansv 2,9 comprised of a lever arm 30 pivotally mounted atone end 31 to the supporting frame 11 adjacent the driving pulley 17, and having an upper portion 32 extending toward the driving pulley 17 with an upwardly flanged end portion 33 alignable with the belt engaging portion 20 of said pulley.
  • the end portion 33 has the usual type of brake, lining material 34 (e.g., leather, asbestos, etc.) affixed, thereto.
  • Spring means 35 is connected between the upper portion 32 and supporting frame 11 and biases the lever arm 30 toward the driving pulley 17 so as to bring the end portion 33 of the lever arm into contact with the belt engaging portion 20 of the driving pulley 17 when the apparatus is disposed as shown in Fig. 8.
  • a bracket or cam means 36 which has an upwardly extending portion 37 having an angular cam member 38 on its upper end 39 as shown.
  • the cam member 38 is engageable with the lever arm 30 when base plate 10 is appropriately rotated, to bear against the lever arm 30 and move it away from. the driving pulley 17 against the bias of the spring means 35.
  • the base plate 10. may be. cut. away as shown in Figs. 6 and 7 to permit a close disposition of brake means 29 and cam means 36 relative to the spindle 15, or they may be mounted in any other suitable fashion just so the proper interaction is achieved.
  • FIG. 1 A typical spinning frame installation is shown in Fig. 1.
  • Two pairs of spindle units 40 are vertically disposed on opposite sides of a horizontal driving cylinder 41, and a driving belt 42 is disposedaround the driving pulleys 17 of. all the spindles 15, around the driving cylinder 41 and an adjacent tensioning pulley 4 3.
  • the belt 42 passes from the driving cylinder to one. spindle 15of each pair and thence directly in a straight flight to the other spindle of said pair, as shown. This is the normal operating arrangement of the respectiveparts.
  • the location of the first hole 27a in the frame H is not so critical, and can be positioned so that the. idler pulley 18 is not wholly disengaged from the belt 42, although the better practice now appears to. be that complete disengagement of the two is more advisable.
  • Limiting means may be provided to permit swinging of the base plate 10 only along the shorter are between the locations of the two holes, as above described.
  • idler pulley 18 may be mounted on a goose-necked shaft 441,0 bring it in closer proximity to driving pulley 17-and thereby decrease the angular rotation of the base. plate 10 required to effect separation of the belt 42: andithe driving pulley 17.
  • each spindle having a rotatably shiftable base plate, an idler pulley rotatably mounted on said base plate, said base plate being reversible shiftable from a first position wherein said driving pulley is operatively engaged with said belt and said idler pulley is disengaged therefrom, to a second position in which said idler pulley is engaged with said 'belt and said belt is disengaged from said driving pulley, a spring biased brake means mounted on said frame adjacent said driving pulley and engageable therewith in said second position, and cam means mounted on said base plate for holding said brake means out of contact with said driving pulley in said first position.
  • a spinning frame having a plurality of spindles driven by a belt from a driving cylinder, each spindle having a driving pulley engaging said belt and a rotatably shiftable base plate, an idler pulley rotatably mounted on said base plate, said base plate being reversibly shiftable from a first position wherein said driving pulley is operatively engaged with said belt and said idler pulley is disengaged therefrom, to a second position in which said idler pulley is engaged with said belt and said belt is disengaged from the driving pulley, said idler pulley being engageable and disengageable with said belt in effecting the above positions Without disturbing the alignment of said belt with said cylinder, a spring biased brake means mounted on said frame adjacent said driving pulley and engageable therewith in said second position, and cam means mounted on said base plate for holding said brake means out of contact with said driving pulley in said first position.
  • each spindle unit having a driving pulley and a rotatably shiftable base plate, an idler pulley radially disposed on said base plate relative to said driving pulley, said base plate being reversibly swingable from a first position wherein said driving pulley is operatively engaged with said belt and said idler pulley is disengaged therefrom, to a sec ond position in which said idler pulley is engaged with the straight flight of said belt and said belt is disengaged from said driving pulley, said idler pulley being thereby engageable and disengageable with respect to said belt at a portion thereon intermediate the spindles of the respective pair without disturbing the alignment of said belt with respect to said cylinder, a spring biased brake means mounted on said frame adjacent said driving pulley and engageable therewith
