SPECIFICATION forming part of Letters Patent No. 276,667, dated May 1, 1883. Application fnea november 14, 18st. (No model.)

To all whom it Amay concern: t

Be it known that I, ROBERT L. CARR, of the city of Fall River, in the county otBristol and State of Massachusetts, have invented certain new and useful Improvements in Warping-Machines; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description of my invention.

In order that the mechanical features devised by me and the novel mode of operation involvedin the use of my warpers may be fully eoinprehended in connection with the ends l seek to thereby attain, lwill state that the beaming ot' yarn' spun on mules in cops has heretofore involved the use ot' a spool-staxid and spools, upon each of which yarn has been laid in the operation of spooling, as it was drawn from a stationary cop, by an endwise draft of the yarn in a line substantially parallel with the axis of the cop.

The warping of yarns from quill-bobbius a used in ring-frame spinning has heretofore in many eases involved the use of a skewer-stand `and skewers, upon which said bobbins are fitxedly mounted, so that the'yarn is drawn therefrom through yarn-eyes on its way to the beam by an "endwise draft of the yarn substantially parallel withthe axis ot the bobbin; but insome cases warps have been spooled preliminary to warping by backwardly rotating the ring-frame bobbins on which the yarn was spun; and also such bobbins have been mounted on skewers or spindles in a stand, and the yarn has been drawn therefrom on its t way to the beam by backwardly rotating the drawings, I do so merely for the purpose of illustrating how suitable cop-supportin g spindles as used by me may also be used for supporting bobbins in a warping-machine.

The prior systems ot' beaming,iwherein the yarn is drawn endwise either from a mule-cop t or from a ring-frame bohbin, involve the introduction of an extra twist into the yarn during its transfer from the cop to the beam, :and this extra twist is put into the yarn duringits transfer for the reason that in both cases the yarn is drawn ofi' endwise from stationary bodies of yarn, and in lines substantially parallel with the axis ofthe cop or the ring quillbobbin, as the case may be. It is well known that the bodies of yarn as furnished by the spindles, whether in the form of detachable cops or carried on the quill-bobbins, are more or less liable to"`become broken, so as to render the further delivery of yarn therefrom by the particular endwise draft referred to practically impossible, and consequently much waste occurs, for when a cop ora quill-bobbin thus fails to deliver more or less of the remaining yarn is usuallyvthrown aside as waste, and to obviate this waste is the prime objectof my present invention. i i

It is also well known that spoolstands occupy so much space that the large number of yarns ordinarily required .for a beam, or even a half beam, cannot be drawn in at one operation; and a further object ot my invention is to enable with coarse warps an ordinary beam to be lled, thereby greatly economizing not only in mill-space and in extra spooling-machines and extra warping-machines, but also in the cost of attendance both for spoo'ling and warping. t.

I am well aware that the prior warpers hereinbefore referred to, which take yarn directly from ring-bobbins, enable more ends of yarn to be worked than when ordinary spool-stands are employed; but by reason of my invention I am enabled to occupy still less spaceiin working a given number of ends, and to readily, with coarse yarns, for instance, work enough ends to euableat, one operation a beam to be properly filled for weaving; and with some classes of yarn I am not only enabled to work a larger number of yarns than can be worked from aspool-stand, but by obviating the labor and expense of spoolin g Iam enabled to greatly reduce the cost of warping, and to reduce the waste from broken or damagedcops to a minimum. i i

In accordance with my invention l beam directly from the mule-cops 5 but `instead of drawing the yarn therefrom while saidieop remains fixed and non-rotative, as heretofore,

ICO

the yarn is drawn therefrom in lines substantially at right angles to their axes, and said cops are permitted to revolve backwardl y during the draft of the yarn therefrom on its way to the beam, and therefore the yarn is beamed ,without further twisting it.

My said invention consists in the combination, with warp-beaming mechanism, (of any approved type,) ofa yarn-delivering stand containing cop-supporting spindles, which yield slightly and permit a cop to rotate backwardly .thereon or therewith during the draft of yarn from the cop on its way to the beam. These cop-supporting spindles occupy so little space in their stand that three or four of them need occupy no more space than a single large spool as usually employed, and as compared with the prior bobbin-stands I can work about twice as many endsin a given space. rEhe backward rotation of the cops and their ca pacity to vary their position obviate their breakage and the consequent waste thereof, and for the first time, lso far as my knowledge extends, l am enabled to place the yarn upon a beam from cops in exactly the same condition as to twist that it was left in by the spindle. The cop-supporting spindles should-be so proportioned, constructed, or arranged that they can be slightly bent, moved, or deflected under the tension ofthe yarn, so that in the event of an imperfect cop said spindle will permit the cop to sufficiently' change in position to enable the yarn to practically free itself from any ordinary break or snarl in the cop. It will readily be understood that spindles which are small enough to properly receive and support a cop and permit it to rotate freely must of necessity be also capable of so receiving a bobbin as to permit said bobbn tofreely rotatebackwardly in the delivery of yarn therefrom.

To more particularly describe my invention, I will refer to the accompanying drawings, in which Figure lis a side elevation of one of my improved beaming -machines or warpers. Fig. 2 is a rear view of a portion of the yarndelivering stand of the machine. illustrate different spindles suitable for my purpose.

The yarn-delivering stand A is a vertical rectangular frame, and it is provided with numerous horizontal bars, a, upon which are mounted a large number of cop-receiving spindles, b, and, wherevernecessary,1provide yarnrods c, for securing a proper draft upon the yarn-z' e., a draft substantially atright angles to the axis of the cops d when placed upon their spindles. These spindles must of necessity be somewhat longer than the cops, and for the best results sufficiently smaller than the spindles on which the cops were formed to enable them to revolve freely thereon. As a rule said spindles need be but little,if any, heavier than ordinary knitting-needles, and the more flexible and yielding they are the better will they be suited for this purpose, provided they are capable of properly supporting a cop while Figs.3 to 6` permitting it to -freely rotate. Spindles which are in themselves stiff and practically inexible may be employed with fairly satisfactory results, provided they are small enough to leave the cop free thereon and have yielding foot' me March 7, 1881, pertainingto the recovery of yarn from broken or injured cops, I have shown and described several forms of spindles which are suited to my present purpose; and I am well aware that some spindles heretofore used for spinning have sufficient lyielding capacity to warrant their use in accordance with my invention.

In Fig. 3 of the present drawings the spindle bis inflexible; but it is provided with a yielding head-bearing and a yielding foot-bearing, and in this case the spindle may be such as is used for spinning, and arranged to be readily detached from the mule and placed with its load of yarn directly into the warper,

.beaming-machine, because it embodies a deadspindle, b', provided with a revolving sleeve, 112,011 which the cop is formed, and a whirl, b3, on said sleeve is used for rotating the sleeve for-spinning, the whole being readily removed from its seat in the spinning-machine, and as readily placed in the beaming-machine. With this form of spindle, mounted as shown, it will be seen that it can yield slightly to the tension of the yarn because of the yieldingl socket, and also that the cop can be freely rotated backwardly with the sleeve in drawing the yarn therefrom.

In Figs. 5 and 6, I illustrate how laden ringbobbins may be successfully mounted upon a small flexible non-rotative spindle like those shown in Fig. 1. A tapered metallic sleeve, e, has at its inner upper end a bearing, which rests upon the top or point of the slender spindle b, so that it can freely revolve thereon. The ring-bobbin f is placed over said sleeve e, so that the latter supports the bobbin at its upper end, thus enabling the bobbin and sleeve to be freely rotated backwardly in the delivery of yarn. When thus mounted the upper end of the bobbin can be swung slightly to and fro under tension of the yarn, because of the flexibility of the spindle, and the lower end'of the bobbin can also vibrate slightly, because the interior of the lower end of the sleeve is larger than the spindle. If desired, the cops may be mounted upon tapered sleeveslikethatshown, and with them be mounted upon the spindles IDO IIO

b. I deem it preferable for the best results that long paper cop-tubes be used in spinning. Other illustrations of suitable cop-supporting devices might be given; but these are deemed ample for thepnrposes of this specification. In some cases, as when warping from bobbns, or from the revolvingmetallic tapered tubes, or from the spindles on which the cops were formed, it is desirable to employ therewith friction devices for preventing them from `rotating too freely or rapidly under the draft of the yarn therefrom.

It is to be distinctly understood that although I have described and illustrated ring-frame bobbns as delivering their yarn directly to the beam my invention includes only such` spindles as by reason of their form and dimen sions enable them to be used as cop-supporting spindles, and that I have described and illustrated ring-framebobbins as used therewith to show that spindles capable of receiving a cop, as described, and enabling the delivery of the yarn by a backward rotation of the cop can, if desired, also be used with approximately desirable results for supporting ring-frame bobbins and having the yarn properly delivered therefrom to a beam in a warpin g-machine.

The beam B is mounted and rotated substantially Aas heretofore, and the yarn from the stand passes through the combs or'reeds g and 7L, and betweensaid combs are tension-rolls t' and drop-wires la, theselatter` being Aportions of the usual stop-motion for stopping the machine when a yarn breaks. It will be seen that the yarn when thus placed upon the beam is in the same condition as to twist that it was when on the spindle; andwhile I do not assert that an extra twist is always objectionable in large number of ends may be readily provided for in one yarn-stand.

In drawing 0E the yarn from cops in the manner described a cop is seldom injured, whereas by drawing the yarn, as heretofore, from a stationary cop and over its endV damaged cops are of frequentoccurrence.

`It is generally advisable that a small copstand be provided on top of the warper at its rear end, as shown, inorder that an end from one or moreof the cops thereon may be employed in case threads break or run out from the main cop-stand, thus assuring the full number of threads on a beam. Having thus described my invention, I claim as new and desire to secure by Letters Pa tent- The combination, substantially as hereinbefore set forth, of the beam,its driving mechan ism, the tension device, and a yarn-delivering stand provided with a series of cop-supporting spindles which are adapted to slightly yield under the tension of the yarn and permit cops to be backwardl y rotated thereon or therewith, as set forth.
