BR AIDING MACHINE.

Application filed Aumlst 3, 1923. Serial No. 655,538.

bobbins or yarn-supplies are arranged in.

opposite sets and revolved in concentric orbits about a common axis. Inma chines'of this type the braiding operation is effected by deflecting the yarns from one set of supplies to cause them to follow a sinuous course over and under the supplies otthe other set; instead of by bodily moving the bobbins or yarn-supplies in'and outto pass them by each other.

One object of the present improvement is to provide a machine of the character specified in which the yarns are manipulated through their engagement .with relatively fixed deflectors employed in place of-the usual moving controllers or switches.

A. par icular object of the improvement is to provide a braider in which different patterns or weaves may be produced in the braid by a slight alteration in the arrangement of theparts of the machine, merely the substitution of one interchangeable deflector for another without dismantling the machine or disturbing its mechanism.

Further objects and advantages of the improvement are set forth in the following specification which describes a preferred embodiment of the invention as illustrated in the accompanying drawings. F111 the drawings:

Referring to idig. C1 of the drawings, the present. n' achine is similar in general re.-. spects to an improved. braider invented by Simon 1V. Wardwell and illustrated and described in various U; 5,1Letters Patents as follows: Patents No. 1,00 9 ,504, dated November 1%, 1911; No. 1,032,870, dated July 16, 1912; No, .l, 0 8l,l-7t, dated Decen ber 16, 1913; and No. 1,197 692 dated September 1 2, 1916.

The main operating-inechanism of the ma.- chine comprises, essentially, a base or stand ard 2 provided with a central, hollow, vertical post .3 and an overhanging bearing t for the drivel-shaft 5. At the top of the standard 21s a bail-race 6 for receiving series of balls 7 on whichqthe outer head or turret 10 rotates. The'turret 10 is of substantially inverted.cone-shape and is provided with a circular ball-race 11 arranged directly over the main ball-bearing on thestandartl A second, inner turret or head 12 is mounted to rotate on balls 13 in the race 11 and is provided with a central conitorni cap or corier 14.

The outer turret or head 10 carries one set of bobbinsor yarnsnpplies X mount ed in spaced relation around its circumference, and is formed with circular raceway or track 15 in which are slidably mount ed series o1" lenticularly-shaped carriers or shuttles 16 carrying the other set of yarn supplies Y. As shown in Fig. 1, the carriers '16 are-provided with heels or runners WlllCll slide 1n the grooved track 15.

CZI

The outer turret 10 rotates about the axis of the machine in a clockwise direction, while the carriers 16 revolve in the opposite direction as propelled from the inner turret 12 The two turrets 10 and 12 are rotated in opposite directions by means of a bevel-pinion 17 fast on the inner end of the driveshatt 5. The pinion 17 meshes with the teeth oi a gear-ring 18 secured to the bottom flanged portion 19 of the turret 10; and the turret 12 is driven from a gear-ring 2O tastcned to a depending sleeve 21 attached to the turret and enclosing the central post 3 ot' the frame 2. Power may be applied to the drive-shaft 5 through any suitable means such as the belt-pulley 22 arranged at the outer end of the bearing 4t. Usually, the pulley 22 is connected to the drive-shaft 5 by means oi: a clutch-mechanism which is not herein shown since it may be of any suitable construction as generally employed for like purposes.

The inner turret 12 is connected to propel the carriers or shuttles 16 around the track by means of pairs of reciprocating driverbars 25. The driver-bars 25 slide in inclined slots on the inner conical face of the turret 12 and carry studs or rollers 26 on their under sides which engage with the groove 27 of a cam 28. The cam 28 is termed as a part of, or attached to, the outer turret 10, and as the two turrets rotate in opposite directions the undulatory form of the camgroove 27 effects a rapid reciprocatory motion of the driver-bars 25. Two driver-bars are provided for each carrier 16 and their arrangement is such with relation to the cam 28 that one bar will be engaged with its respective carrier while the opposite bar of this pair is disengaged therefrom. The purpose of this arrangement, which is commonly used in braiders of this type, is to provide that the carriers will be at all times connected with their propelling-means, while also adapting the driver-bars to oscillate to permit the passage of the strands or yarns be tween the carriers and the pro oelling-head or turret. That is to say, as tie yarns or strands 50 from the outer bobbins or supplies X are passed under the yarns y from the inner supplies Y, the respective driver-bars for each carrier or shuttle will be alternately withdrawn and engaged again with the carricr to allow the passage of the strands along the inner edge of the carrier. The arrangement of this part of the mechanism is not herein shown in detail and requires no further explanation since it is illustrated in the patents above referred to and is well known to those versed in the art. buffice it to state that the track or raceway 15 for the carriers 16 is formed in an overhanging rim 29 on the outer turret 10 and this rim is divided into arcuate sections, see Figs. 2 and 3,

whereby a series of spaces or openings 30 are provided in which the yarns play back and forth to pass them to one side or the other or the shuttles or carriers 16 sliding through the track-sections.

The yarn-supplies X of the outer set are carried on brackets 32 fixedly attached to the rim 29 ot the outer turret 10. Suitable tension-means or let-off devices 33 are provided on each bracket 32 for controlling the unwinding of the yarn a; from the bobbin or supply-cop X. Similar let-off devices are applied to the shuttles or carriers 16 to con trol the delivery of the yarns from the bobbins Y, but since such devices are well known and commonly used in the present art they are not herein shown or described in detail.

The construction of the braiding-mechanism so far described is substantially the same as that illustrated in the patents pre viously referred to and my present improve ment comprises, as before stated, a novel and ingenious arrangement of the mechanism for manipulating the yarns to cause their interlacing to produce different patterns in the braid.

In the machines of the pater-its herein re ferred to, and in other machines of the same type, the yarns from the outer set of sup plies are guided in a mean circular path or orbit, and are deflected from this normal course at certain definite intervals to pass them over and under the carriers otthe other set 01'' supplies. The means for guiding the yarns in their normal path IDZIYDCORP sist of V-shaped, crotch-like elements 35 which are formed of wire and held in ex tensions 36 of the brackets 32, as shown in Figs. 2 and 3 of the present drawings. he yarns w from the bobbins X pass from their tension devices through the crotches 37 ot the guides 35, and are maintained therein by the tension on the strands as they draw to the braiding point Z) to merge in the fabric B, as shown in Fig. 1. Conveniently, the guides 35 are arranged to direct the yarns w in a path which will cause them to engage with the inner edges of the pointed prows of the shuttles 16 when they meet the shuttles as the latter travel in the opposite direction from that of the yarns. It is obvious that with such an arrangement all of the yarns 00 from the bobbins X 01'' the outer set would normally pass under all oi? the yarns 3 from the inner bobbins Y so that no braiding action would take place. In order, however, to cause the yarns w to pass above some of the yarns 9 to effect the over and under braiding action, it has heretofore been the usual practice to provide movable switches operating in conjunction with the leading points of the shuttles 16 to deflect the yarns a? onto the outer edges of said shuttles. That is to say, as the yarns i outer edges of the shuttles 16 whenever it is desired to pass said yarns over instead of under the yarns 2 The switches are operated intermittently with their movement timed to cause a certain predetermined "F manipulation of the yarns. In some cases the switches will be in open position, whereby the yarns traveling in their normal course will be allowed to meet the inner edges of the shuttles 16 so that they are deflected inwardly to pass them under the yarns y; while in other cases the switches willbe closed to shift the yarns outwardly onto the outer edges of the shuttles 16 whereby they will ride up over said shuttles to pass them above the yarns yleading from the bobbins Y. As the yarns are thus deflected to one side or the other of theshuttles 16 thecurved or lenticularlyshaped edges ot'the decks of the shuttles act with a further'deflecting effect to guide the yarns past the bobbins Y carried on the shuttles so that there will be no interference with their passage thereover or thereunder. As the yarns m ride alon the curved edges of the shuttles 16 they will play either outwardly or inwardly along the'branches 38 and 390-]? the guides 35, but after each yarn has been passed over or under the .highpoint on the edge of the shuttle it will again be drawn backinto the crotch ofthe guide. 35 so that normally its course will be defined in a mean circular path to cause it to meet the'leading end of the next shuttle of the series in proper relation thereto.

Various types of oscillating and reciprocating switches have heretofore been eniployed to deflectthe yarns asth'ey meet the pointed prows of the shuttles, but in the present invention an important feature of improvement'consists in eliminatingiall such movable yarn-deflecting means or switches. That is to say, inthe present invention it is proposed to employ a fixed switch or, more properly, a fixed deflector which requires no intermittent movement or oscillation to effect the manipulation of the yarns to define their path of movement over and under the bobbins carried by the shuttles.

As herein shown, the fixed switch or defl ector takes the form of a substantially T- shaped element orarm 40 reaching upwardly from the base 2 of the machine, see Figs. 1 and 2, and provided with an upper horizontal cross-bar 41. The arms 40 are pret e'rably mounted on an outwardly-projecting annular rim 42 on the base 2, and are 'pro vided with feet 43 fastened to'the rim by at45 and reach outwardly and upwardly beneath the overhanging brackets 32 which are fastened to the-rim ofthe outcriturrct 10 at 46. The cross-bar or ET-head .41 of each arm 40 isthus brought into close relation with theaouter periphery of the tracksections 29, see Figs. 2 and 3, andirsually this part ofthe arm ismade ,arcuate ,touconform to the circular contour of the track-sections. At the .righthand end of the crossbar {L1 is a downwardly extending inclined guard piece 48 designed to lift the yarns as they come into contact therewith to cause them to ride up onto the top ofth'e cross-bar 5L1.

It is to be understood that braiding machines of the present type may compr-i se any desired numberot bobbins, usually an evennumber, such :as tour, six,.eight, twelve, sixteen, or multiples thereof in one set, and an equal numberfin the other set. In my present invention I may employ in some in stances a number of fixed switches or de flectors equal to the number of bobbins in each set; .while in other cases there may be one deflector for each two bobbins of either set, or any other combination may be employedin accordance with the character or pattern of the braid to be produced. Likewise, may form the deflectors with 1guid- 'ing-arms or cross-bars ,41 of different lengths, whereby they ,willrhave a variable cooperative relation with respect to the shuttles for-the inner set of supplies to thus act with different deflectin effects on the yarn or in definingltheir at of travel over and under theylarns I roin the inner supplies. In this manner the present improved de .flector may be employed indifferent forms to regulate the order of intermeshing the .yarns .to produce different patterns in the braid, andby simply removing one set 01" deflectors and substituting another se of a diiferent type a variety of patternsmay be incorporatedin the .braidiproduccd on'the one machine.

In the present drawings Fig. 2 illustrates at the left how the yarn w from the outer bobbin X is normally directed by the crotch of the guide 35 in a course which will cause it to pass under the pointed end of the shuttle 16 as the latter meets the. yarn in passing from one track section 29 .to anyarn is raised to a positionin which it will meet the outer edgeiof the carrier 16,.rather than its inner edge, to cause itto be passed abovethe yarn g from the bobbin Ycarried on said shuttle. Fig. 8 shows this second yarn w as having passed along-the guiding edge of th9 '-QS fi+ 41 unti it'h s m means of screws 44. The arms 40 are bent a edge of this shu e, th s action was this yarn ac to be passed above two yarns 3 of the inner set of supplies Y. The next or third yarn a: is shown at the right in Fig. 3 as being passed under the inner edge of the tir t shuttle 16, but this yarn will next be passed over the bobbin Y on the next succeeding shuttle 16. The method or op eration of this form ot deflector during the complete braiding operation will be more clearly understood from the following ex planation taken in connection with the diagrammatic views, Figs. 4t and 5.

In Figs. at and the outer yarns are designated 50, a), etc., and the inner yarns 1 3 3 etc, to more clearly indicate the order ot passing the yarns over and under each other as illustrated by these two views The machine illustrated in these diagrams employs six shuttles carrying the inner supply-bobbins Y, and a like number of outer bobbins I; from which the yarns 03 deliver. Only three fixed deflectors or yarn manipulators it) are used with this combination and the resulting effect is as follows: In Fig. the yarn 0c is shown as being free from the influence of the deflectors L0, and it is therefore caused to pass under the yarn of the inner set. The next yarn 13 how ever, is being deflected and held raised out of its normal course by one of the deflectors -10 and it is therefore caused to pass over the next inner yarn 1 The next outer yarn m is tree from the influence of the deflectors and so will pass under the next inner yarn 3' while the next yarn a2 rides on the deflector 40 to pass it over the next inner yarn 2 this same order being observed completely around the machine. It will be noted from Figs. 4 and 5 that the deflectors or manipulatingdevices 40 have relatively long guiding-surfaces and these act to control each outer yarn 00 to pass it over two 01"" the shuttles 16 carrying the supplies Referring now to Fig. 5 it will be seen that the yarn an after passing under the yarn will also pass under the yarn 3 leading from the supply Y on the next shuttle 16, since it remains free from the influence of the controllers 4:0 when it meets the prow of this shuttle. Likewise, the yarn m which has been passed over the yarn 3 as shown in Fig. i, will also be continued in its raised course through its engagement with the deflector 4:0 to pass it over the next yarn 11 In this way each outer yarn 00 is cause to pass first under two of the inner yarns 3 and then over two of them, or in other words, each of the yarns from one set of supplies passes alternately over and under the yarns from the other set in pairs to produce a particular pattern in the braid.

In Figs. 6 and 7 the machine is shown with the same number of inner and outer supply-bobbins, that is six in each set, but the yarn-manipulators or deflectors 40 are illustrated as having cross-bars or guiding edges of less length, substantially half the length of those of the deflectors shown in Figs. 4 and 5. lVith this modification oi the invention the yarns m from the outer set oit supplies will be passed over and under the yarns from the inner set singly in alternate order. This order of passing the yarns a over and under the yarns y will be clearly understood by reference to these two views, in which the yarns are designated by the sanrc reference characters as in Figs. & and 5. As shown in Fig. 5 all or the yarns :0, w, 00, etc, are shown engaged with the de flectors etO, there being six or" these devices in use, instead oi the three employed with the arrangement previously described. Each deflector 40 has a shorter guiding-edge, however, and the result is that all of the yarns so will first be passed above the inner yarns y as shown in Fig. 6, and then passed un-- der the next succeeding inner yarns y as shown in Fig. 7. In other words, the yarn 00 passes over the yarn y, then under the yarn ;z while the yarn iasses over the yarn 3 and then under the yarn 3 and so on throughout the series to produce a pattern having a regular over and under crossing o1 the single strands in alternate order.

Figs. 8, 9, 10 and 11 illustrate how the operation of the machine may be further modilied by removing some ol the supplies to produce a braid from a less number of strands and with different patterns incorporated therein. In these views the bobbins Y are missing from two of the shuttles l6, and two of the outer bobbins X are also eliminated so that there are four yarns in the outer set and tour yarns y in the in ner set. In the arrangement here shown tour deflectors -10 are employed having the longer guiding-surfaces or cross-bars ll, and the resulting ei'iect on the braiding operation is as follows:

In Fig. 8 the yarns m, 03 00 and as from the outer supplies X are shown as raised or diverted from their normal cour e by the deflectors 40 to cause them to pass to the outside of the shuttles 16 carrying the supplies Y, and hence these yarns will all be caused to pass respectively above the several yarns g, 3 3 and y. At the next stage in the operation of the machine, as illustrated in Fig. 9, the first yarn a) will still be support--- ed by the deflector 4&0 so that it will pass to the outside of the next succeeding shuttle which it meets, but as this shuttle carries no supply its conjunction with the passing yarn will have no efl ect on the pattern of the braid. The second yarn 0 at this juncture will have traveled beyond the control of the deflector 40, and having returned to its normal course will be led to the inside o1 the shuttle for the yarn y so that it will pass under this yarn. The third yarn m meanltd) While, will pass tov the outside, of the nestshuttle 16, due to" its continued engagement with the deflector 4 0, but there being no sup' 'il'yfcn this shuttle the effect on the pattern" of the braid will be nil. On the other hand, the fourth yarn or being ,free from the influence of the deflectors will pass to the insid'eo'f the next shuttle and hence under the yarn y Q Referring now to Fig. 10, at the next stage in the eye e the. yarn ,w,\vi11' free from the control (if the deflectors aridwili therefore pass under the yarn f/t while the next yarn s3 is passing to' the outside of the first empty shuttle 16; the yarn 06 being also free from the influence of the deflectors will pass under the yarny and the yarn m 'wi'll pass to the outside' (if the second empty shuttle. At the next stage, illustrated in Fig. 11-, the yarn will be divertedonce more by one ott-he defleetorsro to pass it to the ousi'de of the shuttle carrying the supply Y for the yarn and hence it will pass above this yarn. The yarn 00 will also he influenced by a deflector to pass it above the yarn 3/ likewise the yarns wt and will be deflected to pass them respectively above the yarns 3 and y will thus be seen th a't with the above described relation of the parts of the machine their cooperative action is such that eachof the outeryarrisw will be manipulated to sihua te it through the yarns y of the inner set with an alternate ever" and under b'raiding action, the first yarn a" a'ss'in first over 01163 3111 y, then under the next yarn 3 then over the yarn 1 and under the yarn while the next yarn a will interlace singly with these same yarns in opposite order, that is, first under the yarn y then over the yarn 1/ and so on to complete the cycle.

Otheifi combinations may be arranged as regards the number of bobbins employed and the number and type of deflectors used therewith, whereby to produce still different effects in the pattern of the braid, and in this way my improved machine has a wide amplitude of adaptability for braiding various kinds of fabric with the yarns enmeshingr in accordance with a variety of patterns.

To alter the braider to modify its method of manipulating the yarns, whereby the character of the pattern in the braid is changed, requires only the rearrangement of the parts of the machine or the substitution of one set of parts for another. In brief, to change the pattern of the braid produced on the machine requires only the removing of one set of deflectors and the substitution of another set, this alteration being accomplished very quickly without disturbing the main parts of the braider. The main operating-mechanism of the machine is never a1- tered or interfered with and no adjustment of the operating parts is required as is the ease marines having movable switches which are timed for definite tribes of operases, I i changing the de ectors 40 it is only necessary to remove their screws, and since the deflectors are positioned around the outside of the b raiderthis' can be aceohiplished very quickly and conveniently with- OIIt CllSII'IaIItIlHg of disturbing any of the parts of the bi-aiding-mechanisin and without r earranging or rethreadingthe su'pply- [5 yarns themselves; 7
