Fig. (5 is asection VIVI of Fig. 5.
It will be understood that the illustrated structure constitutes but one of the combing heads of a cotton combing machine, which may have several heads all of identical structure and all driven by shafts extending lengthwiseof'th'e machine, and com mon to all of them. The frame 1 represents one of the intermediate frame uprights which'are located between adjacent heads and form the supports for the longitudinal shafts referred to as well as the other parts. The detail of the framing is not of consequence to the present invention, 1101- is this invention concerned with the detaching and piecing mechanism, nor the drive-head mechanism which may be "constructed according to the usual Heilmann or Na'smith design. The combing head mechanism comprises, in general, a oscillating ca rriage or bearing frame, nipper mechanism carried thereb' a top comb and lapfeed mechanism. 1 he bearlng' frame iscomposed of a cross bed Qand two side legs 3which are journalled below the iiippe'rs and preferably on or concentrically with the comb cylinder shaft 4, so as to be capable of moving the nippersconcentrically to the path of the comb needles. This frame is integrally formed with three pairs of upright posts, of which the pair marked 5, arethe connection lugs by means of which the frame is connected to the rock arms 6 of the longitudinal rock shaft 7. This shaft will be understood to be common to all the heads in the machine and to be appropriately driven by cam or otherwise, in the drive mechanism at the end of the machine. The lugs or posts 5 are each connected to one of the rock arms 6 by a two-part link, one part of which, marked 8, is an L-shaped memberjointed to the lug 5 and receiving the forward threaded end of the other part 9, in a perforation in its offset portion, 10 so that the link, as a whole, is adjustable as to its effective length; this is for the purpose of varying the angular relation between the bearing frame and the actuating rock shaft, and the method of adjustment will be obvious. The off-set end 10 of the link 8 serves as the connection for the nipper frame spring 11, later referred to..,
The two posts of the'bearing frame 2-3 which are marked 12, constitute the support and bearings for the nipper frame and lap feed mechanism, and the two posts, marked 13, are the supports for the arms 14: of the top comb 15. These top comb. arms are hinged to said posts so that the top comb may be lifted and swung back as customary, and each arm. is provided with a lateral car 16 (Fig. 2) carrying a set screw 17, which is adapted to rest on the heads of the front journal cap bolts of the posts 12 and thereby support the top comb, adjustably,
in its normal or working position. The top comb is thus carried by the oscillating bearing frame 2 3, but its position with reference to the axis of oscillation is constant, that is'to say, it is not lowered into the tuft as customary; such comb movement'is not necessary in the present case because the tuftlis raised into thetop comb as later :eX- pl'ained. Thedetail of the top comb audits several adjustments will be understood from the drawings.
The nipper frame comprises a base .or bed part 18 and two upstanding cheek plates 1.9
rovided with gudgeons "by which it ournalled the posts 12 0f the bearing frame; it is also pro ided with upstanding posts 20, connected at their upper ends, to the nipper frame springs 11 above referred to. The tension of these springs tends to rock the nipper frame to the position indicated in Fig. 3, wherein its rear set screws 21 rest against theupper surface of the cross bed 2 of the bearing frame. The nipper frame carries two forwardly located set screws 22, one at each end, the function of which is to engage the top surfaces of the side legs 3 of the bearing frame to limit the extent to which it may rock in the opposite direction. The cross plate 18 of the nipper frame carries the usual cushion plate, and it will be understood that the adjustment of the screws 22 determines the distance of the cushion plate from the path of the bombing needles on the comb cylinder 23,
while the rear setscrews 21 determinelts position when detaching.
The nipper-knife 2a is carried, a'djustably, on two nipper-knife levers 25, each of which is fulcrurned on oneof the posts of the bearing 'fl'llDQfilIlCl. preferablyby the same pin which connects the-actuating link to saidpost. It will be seen in Fig. 2 that the front and rear arms of the nipper knife levers 25 are off-set; the relation of lever to its fulcrum post 5- is also shown in F 6. The two rear arms of the levers are thus brought closer together and are connected by a cross rod 26 carrying a are bowl 27, which is wiped by a cam 28, adjustably carried on the rock shaft 7 when the latter swings forwardly to about the position indicated in Fig. 5, thus opening the nipper jaws, as they swing forward to the detaching rolls. he adjustment of the cam 28 on the rock shaft determines the time of such opening. Whennot engaged with the nip er cam 28, the nipper knife is held closed on the cushion plate by the two upper springs 29, whicn depress the nipper frame and cushion plate until the forward set screws 22 find their predetermined bearing on the bearing frame 8. The nipper springs are connected to the crossrod 26 between the rear arms of the nipper levers and to brackets 29 fixed on a'rod supported in the creel stand. Vfhen the -.nipper knife has been opened by the operation of the nipper cam 28, as just described, the nipper frame springs 11 rock the nipper frame until the rearward set screws 21 engage the cross member 2 of the bearing frame, as above describedr Thus one'set of springs operates to oscillate the nipper frame in one direction and another'set in the opposite direction. It may be noted here that the two jaws of the nipper mechanism, that is, the cushion-plate and the nipper knife, are not ooaxially pivoted asoustomary; the cushion plate, being secured on the bed 18 of the nipper frame, oscillates about the axis of the gudgeon' bearings 12 on the frame 2'3 whereas the nipper knife oscillates about the axis of the fulcrum pin in the lug 5 on the frame 23, which axis is in rear of the gudgeon axis.
tuft into the comb cylinder needles and one ofthe features of this invention. *Tt will be observed further that the use of a moring member, such as the cam 28, as the means for controlling the nipper-s eliminates the back bar and other appurtenant frame parts which have heretofore been common in swinging nipper frame combers and thus simplifies the apparatus.
The lap feed roller 30 is removably supported and pressed down upon th top of the cushion plate by a pair-of lap feed roll levers 31, which are adjustably fulcrumed 32 in slots in the nipper frame posts 20. The feed roll thus swings with the nipper frame. The rear ends of the levers 31 are connected to the feed rollsprings 33 and the upper ends of the latter are connected to the mp per frame posts 20 on the opposite side from the nipper frame springs 11.. The end of the feed roller 30, right-hand in Fig.2, is provided with the usual ratchet box, conta n; ing a ratchet wheel and pawl and pro. l with a lever 34c, which is d achably ccn-- nected to a feed link 35, shown more clearly in Fig. 3. It has heretofore been customary to actuate the ratchet box, such S l, by means of a link, suchas the link .35, which is attached at its rearend to a fixed part of the machine framing, so that as the feed roll advances to the detaching rolls, the lever 34 is held and thereby rotate'sthe feed roll to feed the lap forwardly. According tothe present invention, the feed link moves in phase with the oscillating nipper mechanism and in the same direction but at a lesser or different rate of movement, so that the amount of rotation thereby imparted to the feed roll is the differential of such movements. For this purpose, the
rear end of the feed link is pivoted, ad
justably, to an arm 36 on a lay rock shaft 37 ournalled 1n thecreel stand and provided, at one end of the machine, with a crank arm 33, by which itis rocked. This latter arm is adjustably connected to, and rocked by, a link connection 39 with the pawl arm 4:0'of the creel-feed bell-crank 40- 41. This bell crank is driven from the main rock shaft 7'by a link 42 connecting its arm 1-1 with the creeldrive arm a3 on said shaft.
The oscillation of thebell-crank 404a, im-
parted through the pawl and'ratchet wheel to the creel gears 44, intermittently rotates the creel rollers e5 soas to unwind the la") from the supply roll resting thereon. The organization of this creel-feed is well known and will be clear enough from the drawing, and it may besubstituted by other forms of feed, according to preference, The
This helps in directing the rocking movement of the creel feed bell crank-.4041 rocks the lay rock shaft 37 so as to advance the lap feed linkat the same time as the nippers and feed roll are advanced by the rock shaft arms 6, but the 'rate' or extent to which the link is ad-- Y vanced depends upon its own position on,
the arm 86' andupon the position of the link rod 39 on the crank arm 38. These positions can be changed to give any desired differential movement of the feed roll, as will be evident, and in practice the feed link 35 of each combing head is. permanently set on its arm 36 and adjustment of the lap feed of all the heads is thenmade simultaneouslyin all heads bychanging the'position. of the link 39 on the crank arm 38. This adjustment iseas'ily and quickly made and the adjustment of the creel-feed can be easily accommodated to it, by varying the position of link 42 on the bell crank.
The lap feed apron 46 is made in two sections hinged at 47, in order to accommodate the movement ofthe combing head mechanism relative to the creel stand; it is supported at its upperend on the creel rock shaft 37 and at its lower end on a small cross rod 48 (Fig. 3), carried by the lap feed roll levers 31. these supports. e
The operation of the creel and combing head mechanism, meaning thereby the top comb, nipper-s and feed roll, is produced en- 7 tirely by the main rockjshaft 7 When this shaft draws the bearm'g frame 23 to the rearward po'sitionof .Fig. l, which is the cylinder-combing position, the nipper cam has parted from the cam bowl 27 and the nipper knife springs 29 then hold the nipper knife 24 closed against the tuft on the cushion plate and the nipper frame depressed to its lowest position. Whenthe needle half lap has passedfrom the tuft, the rock shaft swings the bearing frame toward the detaching and piecing rolls, and co-inci'dently, the lap feed. roll revolves to feed the lap and almost immediately thereafter the nipper cam 28 engages the bowl 27 and thereby relieves the spring pressure of the springs 29, on the nipper knife. This allows the nipper frame to swing the combed tuft to its elevated position as the effect of the springs 11, and immediately thereafter the nipper knife opens as indicated in Fig. 5. In this position, the tuft is entered into the bite of the detaching rolls and then drawn ofl through the teeth of the top comb in the familiar manner; on the return movement of the parts the action is of course reversed except that the lap feed roll remains stationary and the pawl rides over the ratchet teeth.
