- This invention relates in general to liber combing machines, and in particular to cotton combing machines operating on the principles of the well-known Heilmann comber. contemplates a comprehensive reorganization of the structure, functions, and motions of the entire machine,'in the effort to produce substantial improvement in its emciency.
- this machine is of course designed to operate upon cotton fibers having average staple lengths varying throughout the range customarily used in the production of combed yarns; this range is usually between 111g inches and 11%; inches, although for nner yarns special cottons having an average staple length on the order of 11/2 inches are occasionally combed with it.
- a leading object of the invention is to increase the production of the comber in terms of pounds of combed cotton produced per hour.- whereby material savings to the mill and in the initial cost of the machines and floor space required, and in the power, upkeep and attendance will be effected.
- Another leading object of the invention is to improve the quality of the combed sliver produced by the machine, so as to make the yarn spun from such sliver cleaner and stronger than heretofore, such improvement residing not only in more complete removal of short fibers and neps and trash while retaining more of the long fibers, but also in the attainment of more uniform ber density in the combed sliver at all points in its length, whereby better drawing and a reduction in the drawing and doubling processes will be attained.
- Further objects are to simplify the machine, both for the purpose of reducing the cost of building the machine itself, and for the purpose of facilitating its operation, its setting and adjustment, and its servicing; and to eliminate or reduce wear and thus the need for repairs and replacement of parts. Still further objects are to provide improved facilities for salvaging and disposing 4of the waste produced in the operation of the machine; and to prevent or reduce ,to a minimum the. production of fly.
- the invention is based on the principle of making the combed sliver uniform in thickness or liber density at all points in its length in the act of piecing up at the detaching roll. This is attained byoverlapping the successive combed tufts each for more than half its length in such manner that the desired uniform thickness or ber density is secured at this location, and preferably through making the combed web, lap, or sheet of the thickness of two, three,
- combed tufts are necessarily sharply tapered oi and thinned down bythe nature of the detaching action, and only these feathered end-portions of reduced fiber density are brought into 1overlapping relation in prior machines, the re'- sulting combed web in prior machines is of single ply construction and maximum thickness or density at midlength of each combed tuft, and of 2-ply nature but of greatly reduced ber density throughout the zones of overlap between each two successive combed tufts. This variation in ber density is. what gives the combed web in the pan of the prior Heilmann type combers its conspicuous and characteristic transversely barred or striped appearance.
- eachv tuft for more than half its length onto the preceding and following tufts which is employed according to the invention to create the predetermined consistent 2, 3, or more, ply thickness of the combed web, makes the beginning of each combed tuft add and the ending thereof detract a much lesser percentage to or from the thickness of the combed web than in prior arrangements, imparting an inherent and visible uniform density to the combed web which persists throughout all subsequent processes into the finished yarn, giving more uniform and stronger yarn and stronger cloth, with greatly reduced doubling and drawing, and with marked reduction in end breakage in all processes.
- my multiply combed lap is formed of combed tufts which preferably are subjected to a draft on the order of .20 or more times by the action of the detaching rolls.
- the top comb is able to do a more complete job of removing the neps and foreign matter from the tail portions ofthe bers making up the combed lap.
- the half-lap subjects each fiber to a'greater number of strokes before release, making it possible to use fewerand hence coarser needles in the standard number of rows on the half-lap, reducing clogging and failure to comb properly.
- the needles can be made thicker and stronger, and thus can be made longer, which in turn permits the increase in the weight of the supply lap while still effecting proper combing thereof.
- a novel pneumatic waste salvage disposal system is provided, continuously removing all waste and fly produced in the combing and detaching actions and depositing it directly in the waste bin; improved means for examining the waste to determine the percentage of ⁇ ber being removed in the combing is also provided, all as set forth hereinafter.

- Fig. 16 is a view of certain of the parts of Fig. 5 in front elevation.
- an outstanding feature of novelty is the use of the rocking movement of small amplitude of rockshaft I3 Vto swing the swing frame II back and forth, and
- the swing frame I I of each head comprises two pendent arms 2
- of the nippers, the cushion plate, so-called, is
- a housing 9, generally rectangular in plan, which wholly surrounds the stripping brush 5, includes the lower half of the combing cylinder, and approaches closely to the surface of such cylinder at the rear of the machine and to the periphery of bottom detaching roll 1 at the front of the machine, whereby all vily produced by the combing action is carried down and away Y from these rolls by a, downwardly traveling air y the comber. as shown in Figs. 3 and 4, where they.
- Two downwardly inclined brackets 39 extend rearwardly from cross-memn .ber 29 at each end thereof, having hubs 4I in To actuate the nippers, an arm 5 ⁇ I is xed on the end of shaft 43 outside one -bracket 39, the upper end of which arm is pivotcd at 53 to a clevis 55 on one end of a threaded link ⁇ 51 passing through a bearing 59 on a fixed part 6I of the frame of the machine, with adjustable stopfnuts 63 applied to the rearward end ofv the link and with an expanding coil spring 65 confined between the bearing 59 and stop-nuts 3.1 located at an intermediate point in the length of link 51.
- spring B5 tends to hold the upper end of arm 5I from moving rearwardly while its lower end attached to shaft 43 moves rearwardly, thus rotating shaft 43 and arms 45 counter-clockwise to force top nipper yjaw 41 yieldingly downward against bottom jaw 3 I, as shown in Figs. 4 and 14, to grip the intervening lap while the fringe of fibers protruding from the jaws is combed by the needles 3 of the needle segment of combing cylinder I.
- stop-nuts 53 bring up against bearing 59,causing link 51 to detain the upper end of arm 5I while the lower end thereof moves forward, thus causing a reverse rotation of shaft 43 which lifts top nipper jaw 41 well away from bottom jaw 3 I, as shown in Fig. 3, permitting feeding of the uncombed lap.
- Adjustment of lower jaw 3I in such plane by means of screws 33 and 31 is provided to insure Vsuch grip.
- the fibers forming the fringe protruding from the closed jaws are gripped much closer than heretofore to the path of the needle points on combing cylinder thereby exposing more of the length of each fiber to the combing action of these needles before being released and drawn forward by the detaching rolls, and also retaining more of the desired full-length fibers which arrive at the nipper jaws in oblique relation to the direction of feed, thus resulting in both more complete removal of short fibers, neps and trash, and in better parallelizing of the fibers, helping to make possible efficient combing of a double-weight lap, coupled with greater economyof bers of usable length.
- the top comb which should enter the fringe forward of the point where the half-lap needles terminate their action, can do so at points near the tails of the fibers thus combed, with important results which will be referred to later herein.
- the nipper jaws close well before the swing frame I I reaches its extreme rearward position of Fig. 4, and the leading rows of needles 3 of the half-lap enter the fringe held by the jaws while the latter are movingrr rearward and before they have reached their point of closest approach to the path of the needles.
- the needles enter the fringe to a progressively increasing depth, .during the passage of the rst quarter of the half-lap, the leading rows making a shallow penetration and the following rows penetrating to full depth as the swing frame dwells at back center while the remaining three-quarters of the half-lap passes and combs the fringe.
- the cleaning out and untangling of the fibers is effected more gradually and progressively.
- the half-lap is extended to encompass one-third of the circumference of combing cylinder I, so that the combing is prolonged throughout this fraction of the machines cycle.
- the usual 17 rows of needles are prefer- 'tightly and fed through the nipper jaws.
- the fibers are gripped by the nipper jaws closer to the path of the needles and thus with the standard rate of feed of the stock of approximately l each fiber is subjected to a greater number of strokes of the-half-lap before being drawn forward by the detaching rolls.
- This factor coupled with the gradual and prolonged nature of the combing action,l makes it possible to effect thorough combing even of a lap of increased thickness with fewer and hence coarser needles having less tendency to clog and thus to fail to comb properly.
- the needles thus set farther apart in the rows, they can be made thicker and hence of increased strength permitting them to be made longer than possible heretofore. Being longer, they can penetrate through and properly comb a thicker fringe, thus aiding in making possible the use of a Supply lap of greatly increased thickness and weight.
- the remaining two-thirds of the periphery of the combing cylinder is of smooth, polished metal and of substantially the same radius as that of the path of the needle points.
- Feed roll 13 has coarse metal flutes, and is at least half again as large in diameter as in prior machines, to handle the double-weight lapwithout puckering. Its journals 15 are held in halfbearings formed in the end-portions of rockers 11 pivoted on screws 19 threaded into the lower portions of lugs 21, the rear extremities of these rockers being pivoted at 3
- rod 89 is pushed rearward to disengage the shoulder at the top of reduced portion 93 from the keyhole slot to permit the rods full diameter to .descend through the circular portion of the keyhole, thus permitting the feed roll-to be lifted and rotated manually to enter the lap thereunder. This done. the tension is restored by pulling upward and forward on handlevSI to put the parts back into the relation shown in Fig. 4.
- Ihe feed roll is actuated by means of a ratchet
- a feed of around .20 inch of lap pernip is commonly employed. The partial unwinding of the lap from around shaft I3 during the forward swing of the nippers supplies a certain amount of slack in theV each arm 2
- the main supply is as usual effected by the driving of lap rolls IIII.
- the novel top comb I comprises a comb plate I
- 1 has a hook I3I formed in its rearward end which hooks over a pin
- top comb I5 adjustably xed in a slot in a lug
- top comb I5 by the corresponding swinging movement of the swing frame as rockshaft I3 is oscillated.
- the path of the needle points of the top comb intersects that of the lower nipper jaw 3
- the combed fringe is much longer than heretofore, on the order of half again as long.
- the top comb is set to enter the combed fringe close to the lower nipper jaw while still entering ahead of the beginning of the uncombed tail portions of such bers, so that the comb enters the fringe more than' half the length of the fibers back from the edge of the fringe.
- the extent of combed fringe infront of the top comb is substantially longer than in prior machines, which makes possible a prolonged feeding movement of this fringe into the nip of the detach.
- top comb The novel mounting of the top comb permits it to be easily swung up out of the way for threading up, cleaning, repairs, and other purposes.
- the detaching rolls include a bottom roll 1 having a fluted metallic surface and of substantially double the diameter previously used, being on the order of two inches in diameter so as to give more extended support to the long combed have no bodily movement in space, except that they are yieldingly pressed down toward the surface of bottom roll 1 by spring weighting means enabling them to rise as the combed tufts enter between them and the bottom roll, such .spring means being strong enough, to insure a, rm grip on the fibers introduced by the swing frame between top roll 8 and the preceding fed-back combed tufts sufficient to draw out the bers and to detach the rear end of the combed tuft from the supply lap as the swing ⁇ frame recedes.
- a feature of theweighting means for top detaching rolls 8, II), is the provision for instantaneously releasing the rolls from pressure and reestablishing such pressure.
- a small stand 4 is affixed to a bracket 6 extending forwardly from the upright I9 at each side of each comber head, and a stud I2 is fixed in a hub in each stand.
- a lever I4 On eachof these studs is pivoted a lever I4 having its upper arm pivotally connected by a bolt I6 to aclevis formed as a part of a yoke I8 which fits over needle bearings 20 positioned on the journals of top rolls 8, I8.
- each lever I4 terminates in an eye through which extends a rod 22 screwed into a boss on a hub 24 rotating on a, rod 26 fixed in hubs in the ends of arms 2-8 which are pivotally mounted' on studs I2 just outside the -arms I4.
- Expanding coil springs 30 on rods 22 are confined between the eyed ends of levers I4 and the bosses on the associated hubs 24, so that when arms 28 and rod 2 6 joining them are swung clockwise in Fig. 15 the springs 3
- a hand-lever 32 which. is provided with a detent in the formof a spring-pressed plunger Working in a boss 34 on the lever and engaging within a, hole in the upper end of an extension 36 on stand 4.
- withdrawal of the spring plunger, by means of the knob 38, from engagement with the hole in extension 36 releases lever 32 and arms 28 for counterclockwise rotation, rst under the push of spring 30 and thereafter by a, manual pull forward on handle 32,'the lock-nuts on'rod -sion 36 in front of the hole and then snapping into the hole therein to hold the parts again in working position.
- the studs I2 also form the pivots for the hubs 48, Fig. 16, of clearer-boards (not shown) which rest by gravity on top detaching rolls 8, I0.
- Top rolls 8, I0 are rotated solely through frictional engagement with the combed tufts which intervene between them and the surface of roll 1 and which are fed back and forth by the rotation of bottom roll 1 in alternately opposite directions as shown in Fig. 13.
- bottom detaching roll 1 starts to rotate counterclockwise in Fig. 4, starting slowly just before the leading fibers of the'advancing fringe protruding from the nipper jaws reach the bite between rolls 1 and 8. end
- Top rolls 8, l0 rotate in clockwise direction for an equal amount of surface travel.
- the ends of the foremost bers are grasped by rolls 1 and] and pulled forward, while the forward swing of the swing.frame, with accompanying forward movement of the top comb, progressively feeds the leading endl of the succeeding bers of the fringe into the nip of detaching rolls 1 and l.-
- the swing frame starts backward as detaching roll 'I completes its counterclockwise movement retracting the remaining bers of the lap out of the reach of the detaching rolls and thus eecting the detachment of the combed tuft held by the detaching rolls from the supply extending through the open nipper jaws.
- the total length of the latter is on the order of 5% inches, depending on the promptness of entry of the fringe between the detaching rolls after the .latter start forward and the length of staple which the machine is set to reject and to throw down as waste, this latter being determined as heretofore by the closeness of approach of the lower nipper jaw to the nip of the detaching rolls.
- the tuft is thin and easily handled by the detaching rolls.
- each successive combed tuft is overlapped for more than half of its length onto its immediately preceding tuft so that the resulting combed web at all points in its length ismade up of at least two superposed combed tufts.
- the detaching rolls are arranged to rotate reversely for a distance of surface travel of around 4 inches.
- a multiply combed web such as shown diagrammatically in Fig. 12 is formed, which is actually 4 plies thick at all points in its length.
- Fig. 13 shows diagrammatically how this -is done, with the head and tail ends of the first combed tuft indicated at' a, a, of the second at b, b, etc.
- the tail end of the last detached tuft end-portion of each tuft, at the top surface of the combed lap, is balanced or equalized at the bottom surface of the lap by the equivalent trailing tapered end-portion of a preceding combed tuft havinga reverse taper, the two tapered end-portions together making up a thickness which is substantially the equivalent of that of the intermediate portions of any one of the combed tufts.
- Between these two tapered endportions lie the full-thickness intermediate portions of at least two other combed tufts, so that the resulting combed web is made up of the equivalent of three full-thickness combed tufts at all points in its length, as in Fig. 12. This may be increased to four or more as indicated in Fig.
- the combed web is given a substantially uniform ber density in al1 sections of its length in the act of piecing up the successive combed tufts, which uniform ber density once achieved becomes a permanent attribute of the sliver formed by condensing the combed web as i hence stronger yarn for the same cont and staple and a stronger. smoother, and more durable fabric.
- the uniformity initially imparted to the sliver' eliminatesv or greatly reduces the need for the conventional manifold doublings and the multiplicity of draftings which such doublings impose in the spinning, in the effort to fili in and compensate for the thin places in the sliver created by the manner of piecing up employed in 'prior combers and resulting.
- Front top detaching roll Il serves to aid the.
- bottom roll Tforwardly As the drafting and detaching rotation of bottom roll Tforwardly is effected at very high speed and occupies less than 1/4 of the machine cycle, the balance of the machine cycle is available and is used for the feed-back, achieving an easy 13 movement which lets the fed-back tufts follow the surface of roll 1 closely, and incidentally re,- Jerusalems the jerk on the combed web in the pan which has resulted in pulling it apart at this point in prior machines.
- the novel housing 9 which surrounds the combing cylinder I from about the level of its axis downward and which also encloses stripping brush performs an important part in making possible the exceptionally long yfeed-back Without tearing or robbing of the combed lap by the combing cylind-er.
- Housing 9 fits very closely about both ends of combing cylinder I and extends into close proximity to the surface of such cylinder at the rear thereof, while its front wall stands close to the fiuted surface of detaching roll 1 and in the vertical plane of the axis of the latter.
- 39 which has its top edge in close proximity to the surface of combing cylinder I, but spaced away from the surface of bottom detaching roll 1 and from the front wall of housing 9 suiiiciently to afford a clear passage between it and such roll, and also the said front wall, for the recoilng combed tuftswhen fed back for piecing up.
- Air is exhausted continuously from within housing 9 during the operation of the machine by means described hereinafter, and the arrangement of the housing causes practically all the make-up air to enter as a continuous downdraft between combing cylinder I and detaching roll 1.
- 39 diverts this downdraft away from the surface of combing cylinder I and forward beneath detachingroll 1 to descend between the shield and the front wall of housing 9, so that as shown in Fig. 13 the fed-back combed tufts are held against the surface of detaching roll 1 nearly to the point where such surface passes the top of the front wall of housing 9, and thence slant forward below detaching roll 1.
- 39 extends throughout the length of housing 9 with its edge close to the line of contact between combing cylinder I and brush 5, and the lower edge of shield
- 53 is shaped to hold the swing frame at its rearmost position for 90 of the rotation of combing cylinder shaft 2, during which period the needles of the half-lap on suchcylinder are combing the fringe held by the nippers, and thereafter to swing the swing frame forward moderately rapidly throughV the major portion of its swingr and then slowly for the nal part of its swing to feed the protruding fibers of the fringe progressively into the nip of the detaching rolls, such action occupying 120 of the cycle. There after the cam moves the swing frame rearwardly through an interval of 150 to its starting point.
- Adjustment of the closeness of approach of the ⁇ nipper jaws, carried by the swing frame, to the nip of the detaching rolls to determine the length of fiber desired to be combed out and cast down' as waste is effected simultaneously for all the heads of the machine by loosening nut
- the drive for the detaching rolls is likewise greatly simplified. It comprises a face cam
- 83 which is fixed on a stud
- 81 which has six studs
- 93 having a larger spur gear
- Small pinions 205 comprising the planetary gears of the unit rotate freely on the six studs, and mesh with both the internal teeth 201 on the ring gear and also with the small spur or sun gear
- This constant rotationof the ring gear adds about an inch to the distance traveled by 'the detaching roll in its forward direction of rotation, whiley drawing out and detaching the tuft. and subtracts this same amount from the motion otherwise imparted by cam
- This is accomplished by members which remain constantly in engagement, instead of through clutches or other parts whichv must be disengaged and reengaged during each machine cycle as heretofore in certain instances, with resulting wear and tear, noise, and loss of setting.
- the only adjustment required in the present structure is that of the angular position of cam
- the drive for the creel rollers comprises a ratchet gear 223, Figs. and 7, within the gear housing and xed on the end of ashaft' 225 extending throughout the length of the machine andcarrying the front creel' rolls
- An arm 221 fixed on rockshaft I3v carries a pivoted gravitating pawl 229 having at its extremity a transverse edge which advances the ratchet each time the rockshaft swings the swing frame forwardly.
- the pivot connecting the pawl to arm 221 is adjustable radially in a slot in such arm to vary the speed of the creel rolls.

- The, stripper brush 5 is driven by chain 233, Figs. 5 and 7, and sprockets 235 and 231 respectively fixed on.jackshaft
- 45 is joined by connecting rod 25
