Specification of Letters Patent.

Patented June 5, 1906.

Application filed August 10,1905. Serial No. 273,533-

To all whom it may concern.-

Be it known that we, OSCAR L. OWEN, residing in Vhitinsville, county of Worcester, and ELWIN H. RooNEY, residing in New Bedford, county of Bristol, State of Massachusetts, citizens of the United States, have invented certain new and useful Improvements in Cotton-Combing Machines, of which the following is a full, true, and. exact specification.

The present invention relates to machines for combing cotton and similar fibrous material, and has more particularly to do with certain hereinafter-described improvements in the construction and means of operation of single-nip combing-machines whereby the same are adapted for safe and eflicient operation at high speeds; and the invention consists in the novel arrangement of the parts and the proportionment of the speed rela tions of the several driving means, as below described, and in the distribution of the work required of the said means, so that the several operating elements of the machine may be operated at high speeds without overtaXing the capacity of any of their actuating means and without detracting from the integrity and uniformity of the combed product.

Referring to the accompanying drawings, in which like reference characters designate like parts throughout, Figure 1 is a side elevation of a combing-machine embodying this invention, with the central portion thereof broken away for the sake of convenience of illustration. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a transverse enlarged section taken on line 3 of Fig. 2 looking in the direction of the arrows and illustrating the relative arrangement of the gearing in the gear-head end of the machine. Fig. 4 is a similar detail view of the two actuating means for the piec- .ing mechanism, in elevation, with parts broken away to show rearward constructions. Fig. 5 is a further detail, on the same scale, of the driven and. driving elements of the clutching mechanism. Fig. 6 is a vertical transverse cross-section of the machine on line 6 6 of Figs. 1 and 2 and Fig. 7 is a slightly-enlarged vertical transverse section through one of the combing-heads of the machine, adapted to illustrate the principle of operation thereof.

The general arrangement and construction of the machine illustrated in the drawings will be recognized as that of the well-known Heilmann comber, which is usually comprised of a row of independent but similar combing-heads (represented by A) and operated by a number of longitudinal shafts which are common to each of them and receive their appropriate motions from the system of gearing shown at the left-hand end of the machine.

The general arrangement of a combinghead will be understood from an inspection of the cross-sectional view shown by Fig. 7, wherein the roll of lap is adapted to be carried upon a pair of wooden feed-rollers 1, and the layer of lap unwinding therefrom passes down the inclined feed chute or apron 2 into the nip of two spring-pressed lap-feed rollers 3 and 4. The lower lap-feed roller 4 is formed on or carried by one of the shafts which is common to the several combing-heads and is rotated at intervals to advance the lap into the jaws of the nipper mechanism. The latter consists of a frame adjustably secured at its ends to the intermediate frame-sup orts between combing-heads and carries a ower jaw or cushion-plate 5 and an upper pivoted jaw or nipper knife 6, which closes against the cushion-plate to nip and hold the end of the lap, which has been projected between them by means of the feed-rollers 3 and 4. The nipper knife 6 receives its properlytimed movement for this purpose by means of a connecting-link 7, which joins the tail ends of the nipper-knife arms 6 to a cam crank 8, which in turn receives its motion from a double-throw cam 9, carried by the main cam-shaft 10, as indicated in the figure referred to.

The nipper mechanism is so located that the end of the lap which protrudes from the jaws thereof projects into the path of rotation of a single-nip combing-cylinder 11, which is carried by a combing-shaft 12, extending the length of the machine and receiv- 'ing its appropriate rotary motion from the gear-head presently to be described. The cylinder 11 carries a needle half-lap 13, consisting of as many rows of combing-needles as can be conveniently located thereon and a detaching half-lap 1 4, which consists of a cylindrical segment, usually fluted. The staple is encountered consecutively by the needle half-lap 13, being thereby combed in the usual manner, and then by the detaching half-lap 14, which presses their forward ends upwardly against the leather detaching-roller 15, which roller rotates with the said half-lap 14 to draw the staple from the nipper-jaws and through the depending teeth of a top comb 17, the tail ends of the staple being therebystraightened out in parallel relation or combed. The staple is thereupon carried forward and presented to the drawing-off and piecing mechanism, which comprises a fluted drawing-off roller 18 and a fluted clearingroller 19, the former of which is formed on the longitudinal piecing-shaft 20, extending through the several heads of the machine and suitably actuated by the gear-head. The leather detaching-roller 15is held byits usual stirrups 15 against the drawing-off roller, and the clearing-roller 19 is also in contact therewith, being preferably held in constant mesh therewith byits horsetails, so that both rollers 15 and 19 partake of the movement of the drawing-off roller 18. The latter has anintermittent rotation alternately in opposite directions, being rotated forwardly about twothirds and backwardly about one-third of a revolution for each revolution or nip of the combing-cylinder. In rotating reversely the combed staple, which is then in the nip of the drawing-off roller, is carried back, so that its tail ends areleft sticking out below the roller 15 and the succeeding detachment of combed staple, which has been detached and carried forward by the cooperating segment 14 and detaching-roller 15, is laid in overlapping relation upon the tail ends of the previous detachment. At this moment the drawing-off rollers are performing their forward rotation, which is at the same surface s eed as the detaching half-lap, and jointly raw the overlapped or pieced detachments of staple forwardly toward the sliver-pan K. The ensuing reverse rotation leaves the tail ends protruding as before, and the next succeeding detachment, combed and detached as above described, is overlapped u on them in the same manner. The piece staple emerges in the form of a continuous sheet from the drawing-01f roller and passes into the sliverpan K, and from thence through the calender-rollers L onto the sliver-apron M, upon which it is fed along to the draw-head D in the usual manner. The foregoing series of operations is common in machines of this order, and further description will not be necessary, it being understood, of course, that the parts not specifically herein described are the same as usually employed and familiar to those skilled in this art.

The present invention is not directly concerned with the specific constructions of any of the-abovementioned parts of the combingheads; but the arrangement of the moving elements should, preferably, be such as to require but a minimum of motion in the accomplishment of their several functions. It is preferred to employ the invention shown and described in the patent application of E. H. Rooney, Serial No. 268,682, filed July 7, 1905, wherein the cushion-plate of the nipper mechanism is stationary and the teeth of the top comb 17 are disposed in permanent adjustment just clear of the detaching half-lap.

The combing-cylinder may, if desired, be of the usual type of construction, the detaching-roller l5 therefor being properly moved into and out of engagement with its fluted segment by any usual lifter mechanism; but it is again preferred, however, to employ the construction of cylinder and detaching-roller shown in the said application and indicated in Fig. 7 of the accompanying drawings, wherein the combing-cylinder is specially constructed so that the detaching-segment is radially higher thereon than the needle-points of the half-lap 13, and the leather detachingroller 15 is mounted on end-supports in a substantially fixed position, wherein it escapes the needle-points, but is engaged by the detaching half-lap and cooperates therewith, as above described, to detach the staple from the lap and present it to the drawing-off mechanism. The forward edge of the segment 14 is beveled, so as to ride under the roller 15 and lift it very slightly without undue shock. tion, however, the several successive operations effected upon the staple are carried out exactly as above described. The combings or noils are removed from the combing-cylinder by means of the rotary cleaning-brush 24, by which they are delivered to the doflingcylinder 29 and removed from the latter by means of the oscillating dofier-comb 30, all operating in the usual and well-understood manner.

In the construction of machines as above outlined it will be understood that the lapfeeding mechanism, the nipper mechanism, and the detaching and piecing rollers are each called upon to make a complete operation for each revolution of the combing-cylinder or nip of the machine.

Referring now to the arrangement of the gearing, whereby the several parts above referred to are properly actuated in the performance of their functions, it will be observed, Figs. 2 and 3, that the power-shaft 21 is provided with four pinions, of which one pinion 22 gears with a spur-gear 23, which is provided with a wrist-pin 23 and crank-arm 25 for properly oscillating the shaft 30, upon which the doffer-knives 30, above referred to, are carried. Another pinion 26 on the said power-shaft is in mesh with an idle pinion 27, which pinion 27 drives the gear 28, carried by the shaft 24 of the cleaning- In the case of either construc-.

brushes 24. (See Fig. 3.) The pinion 31 is in mesh with the large spur-gear 31, carried by the main combing-shaft 12, which, as above stated, is a shaft common to the several heads of the machine and drives the combing-cylinders thereof. The gear 31 carries a stud 50, adapted to cooperate with the star-wheel 51 of a Geneva stop-motion, Fig. 3, for intermittently rotating the spur-gears 52 and 53, the latter of which is fast on the shaft 4, which carries the lap-feed rollers 4. These parts are shown in the drawings in their usual relations, and they operate in obvious manner, so that further explanation thereof is not necessary, it being understood that the several gears referred to serve to drive the several feed-rollers, the cleaning apparatus, and the combing-cylinders.

The nipper-knife and the drawing-off and piecing mechanism are both actuated from the main camshaft 10, above mentioned, and, according to the present invention, this shaft is intended to be driven at a less speed than the combing-shaft 12, so that while it is making a complete revolution the combing mechanism above referred to will make at least two operations upon the staple, and the means for transmitting the motion of the camshaft to the piecing mechanism is divided up into several separate mechanisms automatically brought into driving connection therewith successively or in alternation. As shown herein, the gear 32 on the camshaft is connected through the idle gear 33 with a pinion 34 on the power-shaft 21, so that it is driven at exactly half the speed of the combing-shaft 12, and the piecing-shaft is connected to receive its motion from the cam-shaft as follows: The pinion 35 on the end of said piecing-shaft meshes with the internal gear 36, which is carried on the counter-shaft 37. This shaft also carries two notched wheels 38 and 38, one being shown at each end, which serve as driven clutch members therefor. being respectively formed with ten straightsided notches equidistantly disposed around their peripheries. The notches of the wheel 38 are adapted to be engaged by the pawl 40, which is pivotally carried on the end of the cam-lever 41 and constitutes the driving clutch member for the said wheel. The camlever 41 is a double-sided lever, as shown in Fig. 1, and is j ournaled on the counter-shaft on each side of its notched wheel, so as to swing concentrically therewith. At its lower extremity it is provided with a laterally-extending stud-roller 42, which engages in a groove 43 in the face of the cam 44, and the pawl is mounted on a lateral rock-shaft which has a crank-arm 45, provided with a roller 46, which roller is held against the edge of a disk cam 47 by means of the two springs 48. The cam 47 is secured to the side of the face-cam 44, and the two together constitute,

Both wheels are alike,

in conjunction with the lever 41, a means for actuating the driving clutch member 40 of the notched wheel 38. the lever 41 is caused to swing to the left, Figs. 4 and 5, and when it has accomplished about half of its traverse in this direction the cam 47 permits the pawl 40 to descend under the pull of its springs into one of the notches of the wheel, and the continued movement of the lever thereupon rocks the counter-shaft and internal gear-wheel 36 in a backward sense, causing the piecing-shaft 20 and the drawing-off rollers 18 to perform their onethird backward rotation, above explained. During the entire return traverse of the lever 41 the pawl 40 remains in its notch, and, therefore, causes twice the extent of rotation of the piecing-shaft in a forward sensethat is to say, a two-thirds forward rotationand at the completion of the return traverse of the lever 41 the cam 47 lifts the pawl out of the notch, and the counter-shaft and internal gear 36 are then free to be similarly actuated by means of the other independent clutching mechanism. The latter is located near the other end of the counter-shaft 37, as shown in Fig. 1, and is in every respect similar to that just described except for the fact that the notched wheel 38 is secured to the shaft 37 with its notches alternated in angular po sition with those of the wheel 38, and the driving-pawl 40 is adapted to be driven by its lever 41 and cams 44 and 47 in alternation with the driving-pawl 40. In Fig. 4 the relation of the two driving means is clearly indicated, and it will be seen that when one pawl is in driving connection with its notched wheel the other is elevated or idle, and vice versa, this alternate action being due to the angular adjustment of the two composite cams, as indicated. The pitch of the camgrooves 43 and 43 is of course predetermined to cause a forward rotation of the drawingoff rollers at a surface speed equal to that of the detaching half-lap 14, so that these parts will work properly in unison and without rubbing. By reason of the fact that the work of operating the piecing mechanism is shared equally by the two composite cams the levers 41 and 41 and their spring-pressed pawls are permitted to have a more leisurely traverse back and forth than is the case when but a single actuating means is employed, and ample time is therefore provided for the pawls 40 and 40 to become securely seated in the notches of their respective wheels, notwithstanding the relatively high rate of speed at which the combing-cylinder and the rest of the apparatus are revolved.

It is desirable for the combing-cylinder to be of as smallv diameter as possible in order for it to effectively project the ends of the detached staple into the bite of the piecingrolls, and it is also desirable for it to carry the greatest possible number of rows of As the wheel revolves ICC ' combing-needles, as under these conditions the combing can be accomplished in the most efficient manner and at the highest speeds. The employment of the foregoing arrangement of gearing and cams with a single-nip cylinder revolving at twice the speed of the cam-shaft secures the advantage, among others, of a small-diameter cylinder, together with a relatively long half-lap, as just explained, and thereby renders it possi ble to run the machine at very high speeds without liability of imperfect piecing and without impairing the thoroughness of the combing.

The cam-shaft 10 also drives, through a pinion 60, a spur-gear 61, which is fast on the calender-roll shaft 62, and the calenderingrollers L are thereby driven at the proper speed to conduct the sliver from the sliverpan K and deliver it to the apron M. The nipper-cam 9, which is also carried by the cam-shaft 10, is provided with a cam surface or groove which is appropriate to cause two actions of the nipper-knife for each complete revolution of the cam, and inasmuch as the nipper-knife has but a short range of move ment, by virtue of acting against a stationary cushionplate, the groove in the said double-throw cam may be made of a comparatively gentle pitch and short throw, which permits the said shaft to be run safely at high speeds.
