BBAIDING-MACHINE.

Specification of Letters Patent. P mtgted Application filed May 25, 1910. Serial Nb. 563,178.

Nov. '14, 1911.

To all whom 'it'may concern:

Be it known that I, SIMON W. WARDWELL,

'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 Improvements in Braiding-Machines, of which the following is a specification.

My invention relates to braiding machines and consists of improvements in the stopping-mechanism therefor.

The object of my improvement is to provide a stopping device which will operate first to disconnect the driving means and afterward to apply a braking force to overcome the momentum of the moving parts.

An important feature of my improven'lent is the method of operation of the brake-ring which provides that when the latter is thrown into engagement with the rotating turret of the machine it is forced thereby against wedges which carry it more firmly against the turret to effect a cumulative braking action.

h Iy invention is fully described in the fol: lowing specification, illustrated by the accompanying drawings, in which Figure 1 is aside elevation of a braiding machine, part sectional through the axis to show the operating parts, and illustrating my improl'cd' clutch and brake mechanism applied thereto; Fig. 2, an enlarged plan view of the brake and clutch mechanism with the latter shown in section on the line A--A of l ig. 1: Fig. 3, an enlarged detail view of the detent latch, viewed from below; liig. a, an enlarged side elevation of the clutchmechanism; Fig. 5, an enlarged detail v ew of the detent elements for he clutch meclutnism, looking in the direction indicated bv the arrow f, F1g. 2; F 1g. 6, an enlarged elevation ot a portlon of the brake ring and its o 'iera-ting devices; Fig. 7, an

enlarged plan viewpf one of the upper carriers showing the tension and let-off mechanism for the yarn; Fig. 8, a side elevation of the same; Fig. 9, a plan view of the lower carrier and supply controlling devices.

The main braiding machine shown and described herein is similar in general to that disclosed in my pending application, Serial filed January 12th, 1910, and the stopping-mechanism is similar in some respects to, that described in my previous pending application, Serial No. 493,718,1iled May 3rd, 1909.

E everal important improvements have been made in the means for controlling the c utch mechanism and: the structure and op aration of the brake-ring and these are spa :ifically pointed out hereinafter.

Referring to F: g. 1, the machine consists essentially of the main frame or standard 2 in which are circular ball races 3 and 4 provided with the ballsfi and 6 adapted to roll therein. Mounted on these ball bear- -ings are two turre s 7 and 8 which drive the series of carriers 9 and 10, respectively, 01 l which the yarn supplies 11 and 12 are mot nted. The lower carriers 10 consist of brackets, illustrated in detail in Fig. 9, and ha 'ing suitable tension and let-off devices moi e after, attached rig dly to a. flange 13 of the outer turret-8. Tl e turret 8 is also formed with a circular groove 14 in its outer rim which serves as a ace-way for the runners 15 of the upper cs rriers 9. The carriers 9 have decks of lent cular contour, as shown particularly in F i gs. 6 and 7 and carry tension and let-off lcvices for the plies" 11.

The inner turret upper and lower 7 carries a dish-shaped head 16 on which are mounted. drivers 17 adapted to engage the carriers t) to propel them inthe race-way 14. The two turrets are rotated in o posite directions b a bevel gear 18 moun :ed on the driving shaft 19 and engaging th 3 gears 20 and 21 of the turrets. The under side 1460f the head 16 bears against the u :pcr face of the gear 21 on the turret 8 to take the upward thrust of the gear 18 and also the thrust of the brake-ring hereina'fi er described. The shaft 19 turns in bearings in the overhanging extension 22 of the fi zone 2- and is driven by suitable means, S1101, f0l instance, as the belt pulley 23 adap :ed to be engaged with the shaft through a clutch member 24, see Fig. 2. The yarns a: and y leadnp from the lower and upper supplies 12 and 11, respeetively, to the hr tiding point e, and the lower yarns a: play i 1 slots in the rim of the turret 8 so as to alloi 7 them to pass over and under the upper sup vlies 11. The yarn supplies revolve in opp site directions and the braiding operation etl'eeted by means of switches mounted on a member 26 which rotates with the turi et 7. The switches 25 operate to alternate y close and open the fully described hereinyarn supshaft to drive the machine the bearing 22 is formed with enlargement or rim 39 having a counterbore openings between the carriers 9 and their driving head 16 and are actuated b a switch-ring 27 oscillated b an arm 28 w ich is moved by either one of the interchangeable cams 29 and 30, all as fully described in my pending application first referred to above. The drivers 17 are reciprocated in and out of engagement with their carriers 9 to allow the passage of the lower yarns an under the supplies 11 by means of rolls or studs 31 engaging a cam groove 32 in the rim of turret 8. I

Thedrivin -pulley 23 is preferably adapted to rotate reely on the shaft 19 when the machine is at rest, and is engaged-with the y a novel arrangement of clutch mechanism now described: A clutch-member 24 is secured at the outer end of the shaft 19 by a stud '33 extending throu h its hub anda transverse hole in the sha t. The clutch-member 24 has a tapered face 34 adapted to engage the correspondin internal face 35 of the pulle 23 which sli es longitudinally of the she t to carry it in and out of engagement. Connected with the hub of the ulle 23 is a sliding sleeve 36 through which t e pulley is operated. The sleeve 36 is formed with a flange 37 at its outer end, and secured to the hub .of the pulley 23 is a flanged ring 38 which'overhangs the flan e 37 to provide for connecting the sleeve and pulley to slide together while allowing the latter to turn independently of the sleeve. The en d of an annular 40. The sleeve 36 proiects into the counterbore 40 and a washer 41 is interposed between its end and the end of the bearing .22. The sleeve 36 also has a counterbore 42 adapted to receive a coiled spring 43 which bears on the washer 41 and tends to force the sleeve 36 away from the bearing 22 to carry the pulley 23 into engagement with the clutch-member 24. v

'The sleeve 36 has a second flange 44 midway of its ends, and between the latter and the ring 38 is a yoke 45 formed with abutments 46, see Figs. 2 and 4, adapted to bear on the flange 44 to move the sleeve to withdraw the pulley 23 from engagement with its clutch-member 24. Preferably, the yoke 45 completely surrounds the sleeve and is formed with a projecting lug 47 which bears on the rim 39' of the bearing 22 to guide it in its movement- On its opposite side is an'arm 48 extending alongside the bearing 22 and havin a guiding slot 49, see Fig. 4, through whic a pin 50' projects from the bearing 22. The end of the arm 48 is connected by a pin 51 to the short arm 52 of the controlling lever or handle 53, the-latter be ing fulcrumed on a stud 54 extending up from the boss 55 which rejects from the frame of the machine. 1? second lever 56' mally acts to move the lever. 56

is also pivoted on, the stud 54 abovev tht lever 53.and is formed with two arms 57-an 58. At the end of the arm 57 is pivoted z detent latch 59 having a slight shoulder 6( adapted to engage the shoulder 61 on th& pin 62. The latch 59 is held in engagemenl with the pin'62 by a spring 63 anchored to a lug 64 on the lever 56. A spring 65 connects the end of the arm 58 of the level 56 to the pin 50 and tends to move said lever inLthe direction-indicated by the arrow a, Fig. 2. The spring 65 has a greater tension than that of the s ring 43 which bears on the sleeve 36, and therefore norand yoke 45 to slide the sleeve 36 and withdraw the pulley 23 from engagement with the clutch.- member 24.

The manually moved controlling lever 53 is connected to operate the lever 56- by means of a pin 67 extending up from a .boss on the arm 69 of said lever 53 andprojecting throu h a hole 70 in the arm 57. A clearance or the pin 67 is provided in the hole 70 so that the lever 53 can be moved a slight distance without moving the lever 56. The pin-67 is also adapted to engage a lug 71 projecting from the hub of the latch 59. -When the lever 53 is moved manually in the direction indicated by the arrow a, Fig. 2, the pin first-en ages the lug 71 and rocks the latch 59 to ree its shoulder 60 from the pin 62. As soon as the latch 59 is free from its detent the spring acts to move the lever 56 to shift the clutch mechanism and disconnect the driving-pulley from the driving shaft as previously de-- scribed.

To connect the pulley 23 with its clutchmember 24 to start the operation of the machine the lever 53 is moved in the direction opposite to that indicated by the arrow a. This movement carries the pin 67'away from the lug 71 and against the opposite side of the hole to move the lever 56 in the direction indicated by the arrow 6. The yoke 45 connected to the arm 52 of the lever 56' is thereby moved in the direction indicated by the arrow 0- to release the sleeve 36 and allow the spring 43 to carry the pulley into engagement with it's clutchmember 24.

Referring to Figs. 3 and 5, the former being a bottom view of the latch 59,'it will be noted that the under side of the end of the latch is cut away at 73 so that the shoulder 61. which engages the pin 62 is of a very slight depth. When this shoulder is released from the shoulder 61 on the pin 62 the surface 73 rests on the side of the pin and the 1 top portion 74 of the latch rides over the top of the pin. This provides that only a slight movement of the latch is necessary to--releas'e it to allow the lever 56 to move under action of its spring 65. The beveled 3 "end of the upper portion 74; of the latcliis for anotherpurpose hereinafter described;

the lever fifilis moved to cause the en;

gagementofthe pulley with its clutch, in the manner above i'describechthe movement gagen'lent. The lever 56 is time locked by the lateh'59 to maintain the yoke 455 in" such position as to allow the spring 43 to hold the driving-pulley in operative connection with its clutch. linember. It will be seen that when. the lever is moved far enough to lock the detent latehlthe yoke 45 will have been moved in the direction indicated by the arrow 0 a sufi'icient extentto carry its abutments 46 clear of the flange 44. The sleeve 36 is then free to rotate without contact with the yoke, and turns with the pulley Q? on. account of its engagement with the hub of the illey under tension of thespring at The spring 43 and asher 411. also turn with the shaft and pulley so as to prevent wear on these parts when the machine is running. Then the machine is stopped bysliding the sleeve 30 to Withdraw the pulley from the clutch-member the :t'rictiodbettveenthe yoke and the sleeve arrests the rotation of the latter and after the stopping of the shaft, the pulley is free to rotate without the sleeve as previously described.

,For stopping the machine upon the breaka ge of a yarn or the exl'laustion of the supply I pri'ivide means for autiinnatically releasing the detei'lt latch as now described: The

outer rim of the frame 2 is formed. with' a circular [hinged seat T5 on which is mounted a ring T (1 which 1 term the brake-rang, see F 1g. "1.. This ring is adapted to be moved in the direction of rotation of the turret S, as"

seco'htL-to etl'ect a braking action on the ro-" tating turrets of the machine.

Secured to the ring 76 ad'accnt the clutclr controllii'igdevices is a tripping element or block 77 formed with a beveled .t'ace 78 adapted to engage the beveled end 74 of the latch 59, see Fig. 2. When the ring 76 is moved in the direction indicated by the arrow (Z the beveled face 7 8 contacts with the hotel 74 to release the latch and to allow the lever 56 to be moved by the spring (35 to cause the disconnection ofthe (.lriving devices. A. link 79 connects the block 77 with the latch 59, also Fig. 5, so that after the latch released and the lever 56 moves under impulse of thespi ing 65 the ring 76 will be turned still 'fart 1er on its bearing to effect the braking a1tion as later de scribed. The link 7 9 alsi serves as ai'neans for returning'the ring its initial positioz'i when the lever 56 isnnc 53 to start the machine It will; bef'noted that Where the lii1l79e aga 'es the hole; 80

in the block there i: suhicient to allow the bloekto inovi intoconta ct with the latch 59, to effect its. release, without being rest-rained the ink. H

The initial movement of the ring 76 to release the 'clutch' devizes is efiected' by means of arms 81' arri ,nged at intervals around themachine, see Figs. 1' and 6, and operated by feeler-devim 5 controlled by the delivering yarns trom bi th sets of supplies. Preferably, the-arm's 81 are ful c'ru lned on studs 82 screwed into bl )CkS 83 fastened to the flange 8. of the 'mac line frame 2. The blocks 83 are secured to the flange 84 by means of screws 85 projt cting through slots 86, and a spline 87 fits th a peripheral groove 88 in the flange tokeep'the blocks from turning. On the brake-: ing 7 61 are secured blocks 89, equal in numb er to'the blocks 83, and fastened in'the sam manner by screws 90. passing through slo s 91, and having splines 92 engaging thi groove 93.- The blocks 83 and SQha've co icting' beveled beveled face 96 adapter, to engage a corresponding bevcl 97 on the exterior of the turret 8, see .VVh anthe wedge-bloks and 89 are caused to be engaged by the tulj'i'iing of the ring 76 hey act to raise the latter to engage the ring with the turret as more fully described her #after. i

The arms 81 have slots 98 with which pins 99, driven into the ring 76, engage. It will be seen that .by moving the arms in the direction indicated by the rrow 6,, Fig. 6, they williact to pry the ring t l turn it in the same direction, as indicated 1); the arrow d, Figs. 2 and 6. The UPPELHQI ds of the arms 81, which are preferably c )nstructed of sheet metal, havefan-shaped l ends 109 twisted at right angles "to the lod'y of the arms.

Adapted to coact with. (less ends are feeler rods 101 and 102 arrang ed to slide in bearlngs 1n the brackets 10, :ee Fig. 1. The rod 101 is bent at right-hug les at 103, see Fig.

1, and extends through a hole 104 in the rim of the turret 8, see Fig. (5. Its upper end is tormed with a re at voly long T-arm 105 bent back 'upm'ritsel tand curved downved by the handle lower end out of reach of the ends 100 of the v arms 81.

Referring to Figs. 7 and8, the upper yarn supply 11, represented'by dot-and-dash lines, is supported on a spindle 111 held in 'a bearingiin the deck of the carrier 9; Thetube' on which the yarn is wound fits a holder 112 which is adapted'to rotate 'on'the spindle 11 1 and carries at its lower end a ratchetwheel 113. Arod 114 pivoted in bearings in an upright ,120 carries a pawl 115 at its lower and adapted to engagethe internal teeth of the ratchet-wheel 113 to control the rotationjof the supply. At its upper end is an arm 116 having an .eye through which the yarn 3/ draws as it leads from'the supply. A spring 117 connects'one end of the pawl 115 to a wire arm 118 and tends to keep the pawl in engagement with its ratchet. The arm 118 is pivoted at the lower end of the spindle 111 with its outer end adapted to engage notches 119 in the under side of the carriers deck. The arm 118 can be adjusted in these notches to vary the tension of the spring117 so as to regulate the de gree of tension of the yarn required to release the pawl from its ratchet to allow tlie turningof the supply. Supported in bearings in the upright120 is a drop-wire 121 arranged toproject down through the deck of the,carri er 9. The drop-wire 121 has a crook 122 at its upper end, serving as a guiding eye for the yarn, and is' weighted by a coil of wire 123 fastened around it near its lower end. The yarn y leads from the supply 11. under the crook 122, thence through the eye at the end of the arm 116 and back through the loop of the drop-wire, as shown in Fig. 8. From the drop-wire the yarn leads up to the braiding point .2, see Fig. 1, and as the yarn is taken up by the braiding operation the'tension on it will cause the arm 116 to be swung toward the drop-wire. This releases the pawl from the ratchet-wheel 113 and allows the supply to rotate to deliver the yarn as required. The tension on the yarn y maintains the drop-wire in its raised position against a stop 124 on the upright 120, see Fig. 7, but when the yarn breaks or is exhausted the drop-wire will fall, under influence of gravity, to act on the feeler devices as later explained. i

Referring to Figs. 1 and 9, the lower supplies 12 are mounted on holders 125 sup ported on the spindles 126 on the brackets 10, and have a similar arrangement of letoit mechanism. A rod 127 is pivoted in bearings in the standard 128 and carries a spring-arm 129 at its upper end provided with a guiding loop 130. At' its lower end the rod 127 has an arm 131 connected by a spring 132 to the wire arm 133. The arm 133 is pivoted at the lower end of the spindle 126 and has a hooked end 134" enga the notches 135." The arm,

can e adjusted in thefnotchesisimilarly to the arm 118 on theupper carrier 9;"to

adjust the tension of the spring 1182. A second rod 136 is mounted in the standard 128 and carries a pawl 137 at its lower end adapted to engage theteeth on the ratchetwheel 138. A coiled spring 145 on, the rod 136, see Fig. 1, tends to maintain'the pawl in engagement with the ratchet-wheel. At its up er end the rod 136 carries a spring arm 1 9 adapted to be engaged by' the arm 129 when the latter is moved under influence of the tension on the yarn as. When the yarn is taken up by the braiding action the arm 129 swings against the arm 139 and the latter is moved to release the pawl 137 to 9 allow the supply-holder to rotate and deliver the yarn. It will'be observed that the any .129 has a wide ralllfige of movement to adapt cient length of yarn to it to render a su allow it to pass either over or under the upper supplies without unwinding from th@ supplycopL.

On the under side of the bracket 10 is the feeler-rod 102 adapted to slide in the bearings 141 and 142. coiled wire 143' which serves asv a. weight to keep the rod normallyin position to prevent the engagement of its end with the arms 81. The wire 143 contacts with the end of the The rod 102 carries a' bearing '142 to limit the movementof the s rod in one direction and movement in the opposite direction is limited by a notch 144 inthe hooked end of the rod, see ri hthand side bf Fig. 1, which is adapte to engage the side of the bearing 141. When the tension on the yarn a; is released, either. by breakage of the yarn or exhaustion of the supply, the arm 129 will swing back under influence of its spring 1.32 in the direction indicated by the arrow, Fig. 9. This carries the arm 131 against the hooked end 140 of the rod 102 to project the latter out into position to engage the arm 81.

Having now described the-whole arrangement of my machine in detail the method of operation of the stopping-mechanism and lot brake-device will next be explained. With' 7 i the driving-pulley 23 in engagement-with its clutch-member 24 the driving-shaft is rotated to turn the outer turret 8 1n the di-- and the yarn is delivered as required, as previously explained. When any one of the supplies 11 is exhausted or one of the yarns .y breaks the drop-Wire which is normallysiispended on the yarn will drop into position to contact with. the feeler rod 101. As the turret 7 mtates in the direction: oppo' site to that of the turretS, which latter car if ries the feeler 101, the end of the drop- Wire 12 1. Will-:ride up over the downtnrned end 106 of the cross-arm 105 and act to depressfthe' rod 101. against the action of its spring 110. The end of the rod 101 will I therefore be thrown into position to contact with the head 100 of the arm 81. As the drop-wires 121 andfeelcr-rods 101 are moving in opposite directions, and since there fisthe same nulnher of both around the cir- Wculn-ference of the machine, it will he evident that a drop-Wire will engage with a feeIer-rod almost the instant it falls. The pur ose ofthe relatively long cross-arm 105 istoprovide that the drop-wire shall hold 1 he feeler-r ods 101 depressed during an interval long enough to insure that the rod engag, is one of the arms 8]..

Add to this the iaet that their contacting surfaces. are heir. g forced together to bind one against tie other, and that the greater the pressure of the ring 7 6 ency Will be to rotate the ring and increase its upward pressure, and it Wi l be seen that the braking force is cuinulati' 'e, and. therefore must give a maximum' re tarding effectl to stop the machine. By this: r 'angelnent I 8 take advantage of the IHOITII ntum of the moving parts of the machine a nd convert it into a reacting force to arrest the operation of the machine after the club 11 mechanism ablc'd to stop the machine almost instan taneonsly when a yarn break: or a supply becomes exhausted and the b jOkElll end of the yarn is prevented from rul ning'into the 9 ity of the braid, since the arns can he 'iieood up without making im ierfeetions or acking out ends and it also provides for more economical operation as the operator does not have to patch or rep: ir the fabric.
