SPINNING DEVICE AATD METHOD.

Application filed August 12, 1925. Serial No. 45,792;

Thisinvention is a novel spinning device and method, having to do with the twisting and winding of yarns, including any librous materials or strands such as cotton, wool, silk or artificial silk. The main object of the present invention is to provide a means factors tending to limit the speed; with this invention a speed of 12,000 R. P. M. or higher is attainable. Other objects are, to afford uniformity of twisting action and therefore-abetter product, to eliminate the objection of ballooning-of the yarn between the supply or rollers and the winding point, and'to enable the same device to be used for winding upon tubes or spools of small The present tive advantages of various prior spinning means while eliminating the respective disadvantages thereof; it is such that it is readily adapted to' be applied to existing machines, to replace the usual spinning devices. without alteration; and it is simple, durable and inexpensive.

Other objects and advantages of the present invention will be explained in the here,

inafter following description or will be apparent to those conversant with the subject. To the attainments of the" objects and advantages referred to the present invention consists in the novel spinning mechanism and method and the novel features of combination, arrangement, construction and operation herein described or illustrated.

In the accompanying drawings showing an illustrative embodiment of the invention. F 1 is substantially a central vertical cross section of sufiicient of the mechanism to enable the features of the present invention to be disclosed. Fig. 2 is a top plan view partly in section taken on the line 2-2 of Fig. 1. Fig. 3 is a top plan view of the parts above the line 2'2 of Fig. 1. Fig. 4. is a right-hand elevation of. certain details seen in Fig. 1.

Fig. a view similar to Fig. 3. showing a modified construction; and Figs. 6, 7 and inhib t I 8, correspondingwith Figs. 2, 3 and i, show the said modification.

In the following description there will first be described the stationary parts, among which is a central vertical rod about which the receiving element, spool or tube is placed, the usual driven spindle being here} in dispensed with. Then will be described the positively driven elements of mechanism, including the revolving guide eyes; then the means for traversing these longitudinally of the cop or bobbin. Then will be described the loose or free runningpjarts which hold and control the tube and bobbin, which latter, with this invention, is actuated solely by the pull of the yarn, controlled by retarding means or drag to be described. Finally will be described the lubricating system.

Rigidly secured to a frame part 10, usual to such machines, is shown an upright threaded socket piece 11, cupped at its upper end, and held below the frame part by a nut 12. Held rigidly within the bore of the socket piece by a screw 13 is sho-w'nan upright central post 143;. This post ata'n intermediate point is provided with a. section 15 of reduced diameter forming an' annular oil recess, and above this is a full diameter section 16, then a reduced diameter section 17 formed with a groove 18-, above which is, a cupped upper extremity of the stationary post. Instead of a driven or rotatable central spindle, with its attendant disadvantages, this invention employs a fixed central rod 20, which forms a bearing and support for thespool, tube or other removable receiving element. 1 The stationary rod 20 is brazedinto a flanged base 'piece 2 1 which in turn is secured against rotation in the cupped extremity 19 of the main post 14 by means of a. connecting screw 22.

Power maybe derived from afast running belt 24- operatingon a pulley 25 having :abelt groove 26, and the remainder of the driven parts may comprise the following. The driven pulley is provided or formed with a downwardly extending sleeve 27 which bears. and rotates'up on the sections 16 andlt of the interior fixedjpost. However, the portions 14 and 16 may be replaced by sleeves of bearing metal. The bearing sleeve 27- is shown as having a lower oil hole 281 and an upper oil hole 29 whereby the oil vessel to be described mayfeed into the recess located between the bearing sections 1% and 16 of the main post.

The rotary pulley is shown as formed or provided with a rotary disk 83 at its upper side. This rapidly driven part forms the lower of two opposed rotary disks or rings, the upper one being the annular ring 34:, and these two members being interconnected by stiff rods 35. forming with the ole rotary disk 33.

.The yarn is shown descending, in twisted cond tion, at a, from .the usual rollers or other, supply, then through the usual fixed 3 upper guide eye adjacent the rollers. The

. of the traverse frame.

twisted yarn (L is shown passing through a fast revolving-guide eye 40 mounted directly on the rotary ring 34 at the upper end From 7 this point the yarn descends at Z2 in asubstantially vertical direction. The described arrangement is one of the valuable iteatures of the present 111- vention. Owing to-the fixed length or dis tancebetween the yarn supply. point and the guide eye 4O1the rate and degree oli twistlng is always un form notwithstanding the traversing movement to be described in lay ing the yarn upon the cop. The distance from. the supply to the guide eye 40 and the definite rate (itclriveii rotation of the guide eye, determine the degreeot twisting, whichthereby may be maintained quite uniform. The yarn passes alternatelyaround thebars of the'eye 40, arranged to deliect the yarn and so impose enough drag to in sure. the. described action. Owing to the short length from the supply to the guide eye 40, which is on. the ring 34L, at the top of the device, and the higher tension due to the high speed, the tendency to ballooning is eliminated. V i

From the guide eye 4-10 the yarn 5 passes downwardly to aguide eye 41, which is moved vertically, or longitudinally of the spool, during the winding. The yarn at c passes from the eye 41 directly to the spool.

The ultimate form of the built-up cop or bobbinumay be as indicated at d. The

' twisted strands,,in a uniform condition as stated, are laidlperipherally on the cop by the rotation of the guide eye .41, and without suffering any strain, so that the usrial troublesome breakage at this point is practically eliminated. To an extent this action resembles the winding of a thread upon a spool manually by allowing the thread to slip through the thumb and fin er, which apply; a certain tension on the tiread, but without strain, as these move progressively around the spool, while the longitudinal traversing act-ion builds up the cop of desired iorm. The guide eye 41 is shown mounted on a small and light carriage or slider 42 whlch is capable of slidlng long1-.

tudinally on one of the traverse guides 35 to give the desired traversing motion. The slider 4-2 is shown as formed with a pair of cars 43 drawn together by a screw 4-41 and serving as a clamp for a double finger 4,5 which straddles, and thus engages above and below, a suitable traversing means,which may be the usual one consisting of a blocl; or plate 47 having a circular recess id-sun rounding the revolving parts, and suitably actuated in any wellknown manner tomove the slider and guide eye longitudinally of the spool while laying the yarn in the def sired form. p I y As stated, there is no driven spindle herein, but the spool and bobbin are arranged to be loose or free running, and are advanced onlyby the pull ofthe yarn, but controlled by a suitable retarding means, which there by etlects a diiierentiation in speedsand in? sures both an effective twisting and a regular, tight winding of the yarn. Thus a base 51" of circular form isishown, above] which stands up a conical support forthe spool, tube or bobbin. .These two parts surround the central rod 20 andare loose or tree run ning, and bear lightly upon tlieflanged'base piece 21 which supports the central rod. In

order to keepthe parts in relation a holddown. finger 53 is showninouutcd outhebase 51 and extending under the flange of the support 21. V i

As a retarding-means to prevent the spool and bobbin rotating at the full speed of the traversing frame I prefer to employ a plu- I rality of wings53, in symmetrical relation,

these being shown mounted radially on the free running base 51, and'of such size' and" shape that air resistance efliects a satisfactory retarding of. the rotation. This wlng device or but-terflyis found to be fairly uniform and satisfactory in operation, and the retarding effect can. be of predetermined amount by selecting wings of proper size and arrangement. i I

The tube or spool 57 or other receiving element for the yarn is shownas slightly conical, as is usual in the art, the tuberesting snugly downupon thei ree running base 51 and surrounding the conicaltube support 52. It is Oneadvantageofthe present inventionthat a tube of thesmallest diameter can be usedand thebobbin wound satisifactorily, irrespective of the distance from bobreadily be'used by means of interchangeable supporting members 51, 52.

Acircular oil vessel 60 is showrrsurroimd ing the'rotaiy sleeve 27, this vessel having a 'cover'61 and a filling spout 62. *The'oil is 'ik'ept'in motion by the rotation of the sleeve,

and it is found that pressure and flow throughholes 28, 29 are produced in a manner tokeep' the runi'iing surfaces well lubricated.

The described combination of elements gives "very satisfactory, uniform and efficient operation, permitting high speeds as stated. Many well known adjuncts are to be understood. Thus, for example, the yarn supply rolls or other supply means may be regulated in a usual manner to determine the rate of supply or paying out the untwisted yarn, thereby to control the complementary Winding and twisting operations and the operative effect of the atmospheric retarding means.

The modification of Figs. -8 contains features not in Figs. 1-4. The central fixed post 14 is fitted directly in the frame part by a rib 14 and collars 14:, locked by a nut 12 The cupped upper end 19 of the post receives the fixed rod 20 as in Fig. 1. The drive pulley is differently shaped, but comprises a sleeve 27 rotating on the central post, and oil holes 28 and a rotary disk 33- at the upper end. The top ring 34 is connected to 38* by only two frame rods 35, of circular section, held below in sockets 37 on 33. One of the rods 35 is grooved at 36 to receive a pin 36 projecting from the slider 42. The oil vessel is at the foot of post 1 F, and a wick 60 conveys the oil to the holes 28. The remaining elements may be substantially as in Figs. 1-4.

In the two forms the central rod 20, which has been called non-driven, is shown fixed, but might be free, as is the holder or cone 52, for example by removing the screw 22, or by brazing the rod, not to the base 21, but to the cone 52; in which case the rod will turn with the cone and tube, resisted by the wing device.

Having thus described a preferred embodiment of the principles of my invention, I desire to explain that many matters of design, arrangement, combination and detail may be variously modified without departing from the novel principles; therefore I do not intend to limit the invention to such matters except to the extent set forth in the appended claims.
