[To all' whom may concern Be it known that I, Smelt Wsnbwm,

a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Im rovements in eohanism for Braiding Machines, of which the following is a specification.

My invention relates to improvements in braiding machines and particularly to the mechanism for holding "the take-up reel and winding the product of the machine thereon.

The object of my improvement is to provide means to facilitate the operation of applying the' take-up reel to the machine and removirf'g the reel from themachine after-it has been filled; and to also provide for winding the product of the machine on the reel in regularly laid, systematically wound coils so that the material will be closely compacted in commercial form in condition to be unwound without snarling or tangling.

The invention is fully described in the following specification, illustrated by the ace companying drawings, in which Figure 1- is afront elevation of abraiding machine showing my invention applied thereto; Fig. 2, an enlarged front view of the devices for holding and driving the takeup or winding-on reel; Fig. 3, a side elevation of the supporting devices for one side of the reel; Fig. 4, an enlarged detail view of the reel-driving mechanism; Fig. 5, an enlarged front view of the take-up and winding mechanism for guiding the braid as it leads to the reel; Fig. 6, a side, elevation of the same; Figs. 7, 8, 9 anfl 10, detail views of the mechanism therefor.

.In Fig. 1 I have shown a roti'iry braiding machine, designated B, mounteo on the table or standard T and. driven from a shaft 0' having a pulley p bolted to a pulley p on the line shaft 1. -Mounted on an arbor 8 extending between the logs t, t of the table T is the supply reel S from which is delivered the wire to or other-material over whichthe I fabric is to be braided. The wire 11:, or

other core for the braid, is led up through the center of the'machine and covered by the tubular fabric b-braided from the yarns etc. As the braid'is fabricated about its core to the product is taken up bya takenp wheel W adapted to feed the core through the-machine. As the material bleaves the braiding point a: it is given one or more turns around the wheel W and then leads to a guide-am A and is thence delivered to the winding-on reel R and coiled regularly thereon. The reel R is preferably supported betweenthe legs of two adjacent tables T and T, it being the usual. practice to set-the braiding machines in rows with a slight space-between each two. The novel means for supportingiand driving the take- .up or wind1ng-on reel willnow bedescribed in detail.

Referring to Fi naled in the bearing 3 of a bracket 4 has tened' to a cross-arm 5 of the leg t, and "serves as an arbor for one side of the reel R.

The shaft 2 carries an arm 6 on one side of the bearing? and at its end is a .stud 7 adapted-to engage a hole 8 in the'fla'nge r of the reel It, whereby the-reel is driven through the rotation of the. shaft. The shaft 2 is rotated through a pinion 9 and g. 2, a stud shaft 2, is jour;

gear 10, the latter. being connected to the shaft by a friction-clutcl'l device as now described: Fast on the shaft 2 is a clutch-disk 11 formed with an annular flange12 on: which is mounted the gear 10, constructed as a ring. A second disk 13'. is axially mounted on a stud 14 screwed into the outer end of the shaft 2. The stud 14 has a hand nut 15 at its outer end, and bearing against the inner face thereof is a spider spring 16.

The ends of the prongs 17 of the sprim 16 bear against the-side ofthe disk 13 t0 orce the latter against the face of the gear-ring 10, and the gear, in turn, is forced against the face 18 of the disk 11, By turning the stud 14 the pressure of the spring 16 can be adjusted, to regulate the frictional contact of the disks 11 and 13 against the sides of the gear-ring 10. The pinion 9, rotates on a stud 19 secured in an arm 20 of the bracket 4, see Fig. 4, and carries a sprocket wheel 21 rotatable therewith. The sprocket 21 is connected by a chain 22, see Fig. 1, to be driveudrom the drive-shaft o of the machine in any suitable manner, not here shown in detail. Un the leg t of the next adjacent table 'l",'see Figs. 1 and 2', is hinged a swinging arm 23 which carries at its lower end an arbor or hearing 24 for the opposite side of the reel .R. Preferably .the arbor 24 is formed as a flanged bushing mounted rotatably on the, stud25 driven into a boss on the arm; Referring to Figs. 2 and 3, the upper end of the arm 23 is formed with two owned in the downwardly projecting arms" 558 or t 1% bracket 29. Thebraoket 29 is Mine T. Adjacent the lower end of the arm 23 is a laterally projecting lug 31 formed with 11 slot 352.-- Mounted in a ,bearing on the leg tie a rod 3-1- fOPl'l'lGd with acmnk-erm 35, the extremity of which engage-stile slot The opposite end of the rod 34- is bent to form n handle 36 and by thinning illie latter the arm 23 can be swung too its hearings to wage and disengage'ther arbor 24: with the hote of the reel Referring to 2, after eime side of the" Y I reel hoe been mounted on the arbor shaft-'2 the creel: handle 35 is turned downwardly,

. the rocking guide-arm which recelves the -brei ded material b as it leads from the take up wheel -'W rind delivers it throughthe depending gilide 52 tothe winding-on reel R.

The apm' is formed with a curved, sicklesha'ped t1m'53 supportedeccentricall to the hub 54 b the arms or spokes 55. e .rim s 53 has a flange 56 on one of its sides, see Fig. 6, and on the opposite side is secured e. plurality of disks or washers 57 held by rivets or other suitable means. The material '6 leads over the curved rim 53and is held thereon between the flange 56 and disks 57. Depending from the lower end of the rim 5? is the guide 52, preferablyformed of wire "1 1 into a goose-neck at (513, see Fig. 6, oh forms the guide-eye for the material.

. ends of the wire are held in boresin the logo 59 on the arm A and th length of guide 52mm be adjusted by slid log the wire'through the lugs. Suitablemeans such the set sore s 88, 83 provide '6, to bind the ends of the wire in that bores to retain the guide in its'adjl'lsted position. The guide-arm A is rocked on its bearing to traverse the guide-eye "58 backlanfl forth across the barrel of the reel R to lay'the materiall .on'the: reel' in re arly disposed coils as shown in Fi 1. T e full lines illustrate the position 0 the guide at one extreme of its traverse and the dash lines show the guide at the opposite extreme. By shortening or lengthening the guide-wire 52 as above described the extent oftr'aversc of the guide-eye 58cm be varied to adapt the windingto'difierent widths of reels.

For oscillating the arm A any suitable means 'might be employed but I prefer to make use ofn heart-shaped cam operated and arren ed as follows: Refernng to liigs. 5, 6, and 8, a. stud 60' pro'ects from the bearing 61 of the'bracket 41, eixig'held in its bore by a set screw 62. Mounted rotatably at the end of the stud 60 is a toothed Wheel or ratchet 63 which has attached thereto, or formed i'ntegral therewith, the heart cam 64, seevFigs. 9 and 10. The wheel" 63 end its cam 64 are held in position longi- -;r tndinally of the stud 60 b a novel'device which also applies a' slig t frictional resinnce to their rotdtion, to prevent the it net-wheel from slipping beck or running when d tl" pawl. macho-- r of the wheel 63 and the V61 is'lever 70 adapted to roclr. on the stud .60, see Figs. 7 and apawl 72 pivoted at the dep-ending resents end of the hearing The lever 70 carries '73 and formed with weighted arm 7 Thepointed end of the pawl. 72 engages the notches or teeth 75 on the periphery of the wheel 63 with the weight 74 swinging inside the Wheel to effect said'engagement.

of the pawl from swinging fup too far, from accident or other cause a lug/Z6 is provided on the lever 70 ment of the stud will indicated by wheel W to spoke 78 to the guide 58 as to limit such upward movement. The ratchetwheel 63 is turned in the direction the arrow, Fig; 7, through the upward liftof the lever 70, and movement of the lever is effected through engagement therewith. of

the stud 7'? is spokes 78 of the adapt it to be adjusted in relation to the end of thelever '70 and a check nut 7 9 is provided to lock the stud in its adjusted position. It will be observed that when the stud 7 8 is set to engage the lever throughout only a relatively slight distance the upward movemove the lever but a short distance before the end of the stud slides off the end of the lever. greater movement of the lever is desired the stud 77 is screwed farther through the provide for a longer engagement between the two, and consequently the lever 70 is given a greater lift and the pawl 72 thereby turnsthe wheel 63 through a longer are. lso provide another adjustment for the lever 70 in the set-screw 80 projecting through the lug 81 on its hub and adapted. to be locked by the check-nut The end of the set-screw 89 is adapted to contact with the 83 on the bracket all to limit the downward movement of the lever 70 and this screw theposition of the on to the stud 1 7 is changed so that the timing of engagement between the two can he regulated to vary the movement of the lever as before described. The earn 64 acts through a roll pivoted on the log 86 of the arm A and engaging its periphery to melt the arm afcrnately up and down with a motion simhar to that of a walkingbeam, this movement causing the traverse of before described. he operation of the whole apparat'is is as follows: The supply rccl' S is mounted onv its arbor s and the wire 20 led up through the inachine and given several turns-around the take-up wheel W. The empty winding-on reel R- is mounted at one side of the machine by inserting the end of the arhor Q in it.) ore and enter: 2 the. oi. into position bring the here en the opposite side screwed through one of the v a stud or pin 77 on the take. up wheel W. Preferably When a l I; l l l l l l 1 I. l l 1 keep the mate 36, as before described. As the braid is iahricated about the wire the finished aterial h is fed from the machine by the wheel "W and isled over the rim 53 of the arm AL The arrangement of the washers 57 on the front of the rim 53 provides for convenience in placing the material on the rim, as itis only required to slip it behind each washer in tnrn; and in addition the braid is practically always in full view from the front of the machine so that it can be inspected by the operator from time to time. From the rim 53 the material is led. down through the guide 58 and its end fastened to the barrel r of the reel B. When diiterent widths of reels are used the guide eye 58 adjusted in relation to the arm as before described, and in this way the traverse or throw of the guide can he regir lated as required.

When the machine is operating the pinion 9 will be driven from the shaft 0 and the gear 10 is rotated thereby. The ratio of the gearing between the shaft o'and gear 10 is such as to ordinarily drive the reel R at a speed a trifle in excess of what is required to wind the material on the barrel of the reel. The rate of feed of the product or the machine is, of course, constant and as the material builds up on the barrel in layers the speed of the reel must decrease with the increasing diameter of the winding. In other words, when the winding is being per formed on the minimum diameter the reel must he'rotated with greater speed to takev up the material than when the material is Winding a tively large diameter. '50 provide for I gradual reduction in the speed from st 1. iinish of the winding the clutch-device on. re arbor shaft 2 is arranged to retate the shaft and arm 6 with an inductive drive so that the speed or the reel will ne aeconimodated to the rate of tie livery of the material. To efiect this the spring 13 is adjusted to give just enough riction between. the disk 11. and 10 to rial under tension ile allowing a ccnst tslippege between ie two the rotation reel is gradually retarded icrease in diameter of the Winding. -up wheel W is driven the speed. required for the particular character of faloric being braided and at each rotation oi the wheel the stud 77 on its spoke 78 will the end of the lever 76 and liftthe latter carry thepawl T2 through a short nient. Theend f the pawl mai n engagement with the teeth c -giherv of th wheel tlfi-lhy the ing the handle into osition to be engaiged again.

The rotation of the cam 64 causesthe stud or roll 85 to travel over the peripheral face of the cam from the low point to the high point and back again to the low point. This causes the r01 85 to rise and fall to oscillate the arm A-with a rocking motion and the guide 58' is traversed back and forth across the barrel of the reel It as illustrated in Fig- 1. By adjusting the stud 77 in the spoke 7S and the set-screw 80 in, the" arm 81 of the lever 7 O the length of engagement between the stud and lever can be regulated, as before described, to give a greater or less movement of rotation to the wheel 63and.

a little, owing to cam 64. In this way the oscillation of the arm A and the traverse of the. guide 58 is timed to wind the material on the reel R in close wound coils laid regularly, side by side. As the layers of coils build up on the reel the ratio between the traverse-of the guide andjthe turnin of the reel will vary the retardation of the speed of the latter; but the effect of this is merely to wind the coils a' trifle farther apart or more open and this slight change in the wind is not material. Heretofore in braiding machines the usual practice has been to simply up reel and let the material wind thereon indiscriminately without controllingthe lay ing of the coils. This method of taking up the product of the machine is very unsatisfactory for several reasons: The material when uncontrolled Wlll wind up in a haphazard manner with a heterogeneous mass of coils crossing and recrossing each other and so confused as to prevent 1' cc delivery in unwinding. In some cases where .the coils build up in arelatively narrow mound, the outer coils will slip oil and become loose and subsequent coils laid across these will chafc, bind and crimp the material and damage the fabric to such an extent as to render it unfit for use. Frequently the material will be in such a tangled state that the reel must be unwound very carefully by hand and the product rewound to'render 1t capable of delivering in applying it to the coating or other processes of manufacture. My improved winding device obviates all these diflicnlties now enco mtered and provides for putting the material into such form as to compact a maximum quantity on reel, means to guide braiding mechanism rotate the take- I therefrom, either for other p ap aratus provides for the most convenient an economical operation of the braiding machine and the handling of its product, so that the capacity of the machine is increased and its product improved. a
