Definitions

  • This invention relates to clearers as used in combing machines or other machines for the treatment of textile fibers and more particularly to clearers of the type having both a bodily and a rotary movement such as used for clearing the waste fibers from the leather-covered top detaching rollers of combing machines for comb- 'ing textile fibers.
  • the clearer is usually furnished at at least one end with pawl-and-ratchet mechanism whereby the roller is allowed to turn in one direction and is held against turning movement in the other direction.
  • a combing machine of the modern type usually comprises six heads, there being a clearer for each head.
  • the action of the clearers is accompanied by considerable noise in addition to vibration and wear of the pawl-andratchet mechanism.
  • a main disadvantage of clearers operated as described is that, as Wear takes place, the pawl engaging the ratchet wheel begins to lose its retaining power, and the clearer loses its enicien'cy until eventually it becomes a source of considerable trouble.
  • the present invention contemplates the provision of a revolving clearer which has none of the disadvantages inherent in clearers as above described, being silent in action, free from Vibration, always correctly adjusted, and in which the wear of moving parts is so slight as to be ne ligible.
  • a revolving clearer includes a clearer roller element having .an axle element rotatably mounted in a pair of .coaxially pivoted bearer arms and loaded frictionally acting means, e. g, a dog, wedge, or the like, :on at least one of said arms adapted to impose .zfrictional resistance to rotary movement of said roller in one direction.
  • the dog, wedge or the like is preferably springinfluenced and is engageable with a surface of revolution presented by a bowl or roller fastened on one end of the axle of the clearer roller.
  • the bearer arms are preferably each furnished with an extension to facilitate the lifting of the clearer away from the detaching roller and to minimize risk of injury to the hands of an operator.
  • FIG. 1 is a perspective view of a revolv-mg clearer constructed according to one form of the invention shown separate from the combing machine, the clearer roller being shown broken to shorten the figure.
  • Fig. 2 is a side elevation showing a revolving clearer as illustrated in Fig. 1 applied to a combingmachine, only so much of the combing machine being shown as is necessary for a clear understanding of the invention, and in which the clearer is shown in full lines fully withdrawn from its working position and in dotted lines tilted back in a position to facilitate cleaning;
  • Fig. 3 is a similar view to Fig. 2, but withthe clearer-shown in its working position; Fig.
  • FIG. 4 is a similar view to r Fig. .2 but showing the clearer partly withdrawn to illustrate a feature later to be described;
  • Fig. 5 is a fragmentary side elevation and Fig. 6 a plan thereof, of one bearer arm of the clearer shown in Fig. 1 to which the invention in one of its forms is applied;
  • Figs. 7 and '8 are similar fragmentary elevation and plan views of a modified form of the invention; Figs. 9 and 10; Figs. 11 and 12; Figs. 13 and 14; Figs. 15 and 16 and Figs. 17 and 18 are, respectively, similar elevations and plan views of further modified forms of the invention.
  • a cylindrical clearer roller having a covering l I, of flannel or the like, and revolvably mounted in a pair of bearer arms adapted for pivotal attachment to the weighting lever of a combing machine.
  • Each bearer arm is preferably in two parts, one part l2 being pivoted and the other part l3 being adjustable relatively to the other part l2 and being secured thereto by a set-screw M, the connecting end of said part l3 being accommodated in a rabbeted part
  • each bearer arm is formed at the end adjacent to the clearer roller with an extension or finger I6 whereby to prevent the clearer roller from dropping too low between the detaching rollers in certain positions of use.
  • the part l2 of each bearer arm is formed near its fulcrum end with an extension I'l forming a handle whereby to facilitate lifting of the clearer by an operator and to minimize the risk of injury to the hands of the operator when lifting said clearer.
  • the extensions I! may also serve as stops to limit movement of the bearer arms in one direction and to retain the clearer in suitable position for cleaning.
  • the clearer is mounted in known manner in the combing machine and a typical arrangement of clearer is shown in Figs. 2, 3 and 4.
  • l8 and I9 are the top detaching rollers of a combing machine and and 2
  • the detaching roller I8 is rotatably mounted in bearings 22 in one end of a weighting lever 23.
  • the lever 23 is mounted at its opposite end on a pin 24 in an extension 25 of a lever 26 secured on a shaft 21 journalled in the frame of the machine.
  • the lever 26 is in operative connection with an operating shaft, not shown, by means of a rod 28, shown broken.
  • the weighting lever 23 is weighted in known manner by means of a weight attached to the arm 29 (or by a spring).
  • a plate 30 Secured to the pivot pin 24 is a plate 30 adapted to move in unison with the weighting lever 23 and formed with an elongated slot 3
  • the clearer In its working position the clearer is pivotally mounted in the plate 30 on a pin 33 projecting from a lug on the bearer arm I2 of the clearer and resting in the lateral extension 32 of the slot.
  • the weighting lever 23 is rocked about the pivot 21 to move the detaching roller I8 from the position shown in full lines in Fig.3 to the position shown in dotand-dash lines in the same figure to allow the top comb to drop into operative position.
  • the clearer is reciprocated to and fro by the same movement of the said lever.
  • an axle 34- of the clearer roller Ill projects through the part
  • a dog 38 Fulcrumed on a stud 33 secured in said part I3 by lock-nuts 3'! is a dog 38 the free end of which is formed with a cam surface 39 and held in yielding contact with the bowl 35 by means of a light plate-spring 40 secured at one end by a set screw 4
  • clearer roller Ill being alternately free to rotate and held against rotation as in known forms of clearers with the important difference that the bowl 35 and dog 38 work smoothly and silently and the clearer is free from vibration.
  • are rotated in unison intermittently and alternately forward and backward in the known manner of a Nasmith combing machine, and are usually of steel with serrated or fluted surfaces.
  • the clearer roller l0 normally rests on the top detaching roller l8 and partakes of the translatory movement of the top detaching roller l8 relatively to the bottom detaching roller 23.
  • are rotated in a forward or counterclockwise direction and during this rotation the clearer roller [0 resting on the top detaching roller I8 is prevented from turning in the direction of the arrow B, Fig. 1, by the wedging action of pawl 38 upon roller 35.
  • a backing off action is performed, whereby to draw the combed cotton fleece back, to make accessible combed fleece to which succeeding fleece is overlapped so that on the next forward movement of the detaching rollers both the first and succeeding fleece are drawn through the rollers.
  • the amount of wear of the dog 38 and bowl 35 is infinitesimal, and any wear that does take place is compensated for throughout the time the clearer is working through the influence of the spring 40.
  • the working parts are of ample size to ensure long working life.
  • the dog may be located in a recess in the side of the bearer arm and be covered by a plate to exclude dust. Further, instead of acting on a bowl fast on the axle of the clearer roller, the dog may act directly on said axle, the bowl being dispensed with.
  • Figs. 7 and 8 Such a construction is illustrated in Figs. 7 and 8 in which parts corresponding to those in Figs. 6 and 7 are indicated by the same reference characters distinguished by the addition of the exponent a.
  • 3a of the bearer arm is formed with a recess
  • the clearer roller Illa is alternately rotated and held against rotation as in the first described construction.
  • a metal cover plate 43 is provided and held in position by screws 44, 45 and by a circular spring clip 46 embracing the projecting axle 34a and fitting in an annular groove therein.
  • a wedge-shaped dog adapted to co-act with a V-grooved brake drum on the axle of the clearer roller.
  • Figs, 9 and 10 Such an arrangement is shown in Figs, 9 and 10 in which parts corresponding to those shown in Figs. 1 to 6 are indicated by the same reference characters distinguished by the addition of the exponent b.
  • the wedging action may be obtained by means of a steel ball or roller working under spring influence in a camshaped cavity in the bearer arms and adapted to engage a bowl on the axle of the clearer roller, or the axle itself.
  • a steel ball or roller working under spring influence in a camshaped cavity in the bearer arms and adapted to engage a bowl on the axle of the clearer roller, or the axle itself.
  • Such a device is shown in Figs. 11 to 14 inclusive.
  • Figs. 11 and 12 in which parts corresponding to those in Figs. 1 to 6 are indicated by the same reference characters distinguished by the addition of the exponent c.
  • the part l 30 of the bearer arm is shown formed with a hollow boss 48 in which is located a. steel ball 49 normally urged into contact with the surface of the bowl 350 by a spring 50.
  • the pressure of the spring may be adjusted by means of a plug 5
  • the roller or bowl 350 turns freely against the slight resistance offered by the spring-influenced ball 49.
  • the bowl 350 presses the ball 49 downwardly and causes it to wedge in the boss 48 and prevent rotation of the bowl 350 and the clearer roller I00.
  • the bowl 350 is dispensed with and the ball 49d acts directly upon the axle 34d.
  • a wedge-shaped plunger may be employed instead of the wedging action being effected by a ball.
  • Such constructions are shown in Figs. 15, 16 and 1'7, 18 in which parts corresponding to those in Figs. 1 to 6 and Figs. 11 to 14 are indicated by the same reference characters distinguished by the addition of the exponents e and f, respectively.
  • Figs. 15 and 16 show a springinfluenced wedge-shaped dog 52 adapted to press against a bowl 35c.
  • Figs. 17 and 18 show a spring-influenced wedge-shaped dog 52f pressing directly against the axle 34 of the clearer roller I01.
  • the provision of the extensions l1 forming handles at the rear ends of the bearer arms facilitates the raising of the clearer for cleaning purposes and ensures that the hands of the operator are not placed in a dangerous position, as may be the case with the ordinary construction of bearer arms, thereby minimizing the risk of injury to an operator raising the clearer for any purpose, for example, to clear said clearer of accumulated fly.
  • Fig. 2 shows in full lines the position of the clearer when it is first drawn back by the operator by means of the handles I1 until the pivot pin 33 is engaged in the extension 32 in the slot 3
  • Fig. 4 shows the clearer roller partly withdrawn and also shows the extension l6 resting on the arbor of the top detaching roller l8, thus preventing the clearer from falling too far down between the said roller is and the second top detaching roller l9.
  • backward movement of the detaching roller l8, towards the position indicated in dotted lines in Fig. 2 would cause the extension l6, by reason of its cam-surfaced under part, to ride up the aforesaid roller I8 and so raise the clearer roller In to correct working position.
  • a revolving clearer for textile combing machines having a detaching roller, including a pair of co-axially pivoted bearer arms, a covered clearer roller element adapted to engage the detaching roller of the combing machine to remove waste fibers and having an axle element rotatably mounted in said arms, one of said elements presenting a continuous surface of revolution, and loaded one-way acting frictional means sustained by at least one of said arms and engageable with said surface of revolution, said frictional means acting to impose frictional resistance to rotary movement of said clearer roller element in one direction and to permit silent rotation of said clearer roller element in the opposite direction.
  • a revolving clearer as claimed in claim 1 including a bowl fast on one end portion of the axle element and presenting a surface of revolution, and a spring-influenced dog mounted on one of said bearer arms and having a cam face engageable with said surface of revolution and adapted to resist rotary movement of the clearer roller element in one direction.
  • each bearer arm is provided with an extension to serve as a handle, said extension being adapted to engage an abutment in out-ofuse position of the clearer.
  • each bearer arm is formed with an extension engageable with the arbor of the detaching roller to prevent excessive falling movement of the clearer roller element.
