anisin. Fig. Z'is a detail elevation of a portion of the said mechanism. Fig. 8 Vis a detail side elevation of the brake device.

While l.- have found the avoidance of a reciprocating motion or movement of the threaddirecting member heretofore commonly employed to operate the thread from the lower vbobbins to be eminently practical as disclosed l in my said Letters Patent, I shallprese'nt in the description which follows certain modiii-v cations inthe construction of minor parts de signed to. cooperate withv my rotating thread- .directing -member above. referred to which will in certain instances vmore reliably accomplish the desired lresult of plaiting or incorporating thethreads from both sets ofbobbins at the proper braiding-point and which will insure the most harmonious cooperation of all the elements of my braiding-machine, thereby removing `undue strain from the threads at the braiding-point and accomplishing other desirable results hereinafter made more clearly apparent.

' lt will loe seen that'l have alsoprovided a very simple though' reliably-eicient mechanism for stoppingthe operation of my braiding-machine should a thread from any of the bobbins become broken, and, while I am aware that various appliances with such object in view have heretofore been provided, I desire to call particular attention to the special means hereinafter described, and disclosed in the accom panying drawings.

Referring now to the drawings, lis the base member or support, terminating inthe upwardly-extending reduced tubular section 2. Rigidly secured to the upper end of the tubular section 2 by means of screws 3 or ot-herwise is the stationary body portion or table 4, having the down wardly-in'clined portion 4, the said table being circular in form, theouter edge thereof 'provide-d with the vertical T- shaped circumferential flan ge-segmen ts 5, providing a segmentaltraclk orguideway 6 forcertain 4mechanism to be hereinafter referred to.

Disposed immediatelyl below thetable 4 is the rotating'nieniber or, spider v7provided with down war'dly-inchned outer portion 7EL and ribbed tubular inner portion, which is sleeved and designed to fit snugly `onthe tubular/secl. f realise tion2 andto besnpported on a shoulder on the base member, the said tubular section. 2

serving asa post on which thespider 7 is dcsigned to freely rotate between said shoulder land thesnrmounting' table Lt'.

i 8* represents the lower-bobbin spindles, rig'.- idly secured to the webs .8,l of the inner portion 8 o f the spider 7 an idler 1li. Securely attached to or formed integral with the belt-wheel 13 is a channeled brakewheel 1.5, the object of which will be hereinafter more fully stated. .Mounted upon the segmentaltrack 6 of the .flange-segments 5 are a series of upper-bobbin carriers 16, each ofthe saidjcarriers being. made in two parts 17 and 18, respectively, the Vsaid parts being held securely together kby screws 19 or the like. The upper part A17 is L-sfhaped in cross-section, the short parallel portion or lip 2O being adapted'jto extend beneath one side of the segmental track 6 and Vthe lower part 18 being ,adapted to extend beneaththc oppo-l site sideof--th-esegmental track 6, thus hold-` ing' the carriers 16 securely in place and at the same time providing a means whereby the carriers may be guided upon' the segmental track 6.

lt will be understood; that the number' of bobbin-carriers employed varies and is-regulatedby the size of the machine in use, a large machine requiring more bobbin-carriers than a small machine.

ln order that the upper-bobbin carriers 16 may be positively driven around on the segmental track, provide the lower parts 18 with racks 21,which are meshed by the'gears 22, rotatably mounted upon studs 23, secured to the vertical flangelsegments The gears 22 are so arranged with respect to the bob bin-carriers 16 that. at least one of the said gears 22 will always be in mesh with each of the racks .Z1-that is to say', before a rack 21- has passed 0E `from one of the gears itvrill be engaged by the. next gear in its line ofl travel, thus keeping the bobbin-carriers 16 moving uniformly. The gears 22 are designed vto be meshed by the annular cogway 24, which is carried by the youter portion 7L of the spider-7 and is secured thereto by bolts 24, (see Fig. 6,-) so that as the spider isv revolved the cogway 24i1nparts rotation tothe gears 22. it is preferable to construct the cogway 241- in sections; but il do not desire to j be confined to this particular c onstructiomas any preferred niethodof construction may be adopted. v

.Thefouter edge of the inclined' portion oflthread-guide `97.

- upper-hobbin carrier.-

the spider 7 is provided withan upwardly/cxA tending circumferential flange 2.5, certain portions ot which are formediiixthlfstandards or brackets 26, to which are rotatably mounted v the thread-directing gears 27 by means of studs 28, secured thereto by nuts 28.

To carry the thread from the lower series of hobbins 29 alternately above and below'the threadsrom the upper bobbins'BO and cause the said thread to be interwoven with respect to each other, have extended the standard 26 for the said gear 27 upwardly to provide' depending terminal 93 disposed adjacent to the inner'face of ythe' said gear 27 and designed to afford means for carrying the thread overl the` gear 27. It will be seen that the. branch'92 and terminal `93 are pro vided at proper intervals with thread- guides 94, 95, and 96, through whichthe thread from the lower bobbins is directed safely into position 'to be delivered through the guide 97=to the braiding-point, and inorder that said thread may be. properly manipulated or directed unJ der one carrier 16 of the upper bobbins 30 and over the nekt I provide the-pivoted lever 98, which carries at its free end the said 98 is disposed near the middle thereof, as by providing a slot 93 in the lower end of the terminal 93 and so pivotally mounting the said lever 98 therein that theheaded terminal 99 thereof may be seated in a suitable recess 27, formed in the gear 27 near the outer edge thereof, thereby constitutinga ball-and-socket joint. .lt is obvious 'that-the free ond of the lever 98 will be so moved by the rotation of the gear 27 that the thread-guide 97, carried by the said free end lof the lever 98, will dcscribe a trochoidatpath', successively elevating and depressing the thread, soV that the same will be safely disposed over one upper carrie-r 16 and under the next as the same moves swiftly upon its segmental track 6. lt will be understood that the requisite pivoted connec' tion or relationship between the lever 98 and the terminal 93 may be provided by pivoting the said lever 98`to a girnbal-frame lor carrying member 100, which is provided at its upper and lower ends with the journals or lugs 101, adapted to take into suitable apertures provided in a contiguous part ofthe slot 98", formed in the terminal 93, as 'will be obvious. As the gear 27 is moved bodily onits annular coursetherotation of the said gear 27 will so-actuate the lever 98 that the thread dclivered bythe thread-guide 97 will be moved in a trochoidal path, the openings-33 in the T- shaped flange afording ample room in' which to safely direct Asaid thread downwardly in time to be passed over by the next succeedingr Mol` ion is imparted to the gears 27 by menus of the annular cogway 34, which is held in ifasition by means of a series oi brackets' '37 The fulcrum of the lever the inwardly-directed branch 92, having the IOS lIO

" spect to thetable 4. To insure that the braiding 5, thus -holding the cogway` 34 rigid with repoint or angle may not move below 'the con- -ical surface passing through the axes of the bobbins 30.,

the tubular section 2 a conically-pointed corey guide 36 by means of a lug or lip 36, formed thereon. The core-guide 36"has a core-holeV through it. and its upper end .is centrally ,disposed with respectto the severalfupper bobbins 30. 4 y

Disposed at a suitable distance above the core-guide 36 is a braid-guide 37, the said braidguide being adjustably secured` by a set-screw .373, bearing against the slidable stem 37a of the braid-guide in the end of an arm 38, which is in turn adjustablys'ecured upon a rod 39 by aclamp. 38; The rod 39-isfmountediin inner and outer main -brackets 40 and-41 at either side of the machine proper.' The braid-guide 37 is provided with various-sized holes to ac.- commodate the different sizes of braid., and

its stem can be rotated so asv to bring the desired hole over the hole in thecore-guide 36. Mounted upon the rod 39-and adapted to be rotated freely thereon is a'grooved pulley 42,

-one edge of which is provided with teeth 43.

The grooved pulley 42 is designed to serve as a take-up or tension for the linished braid and iscaused to rotate bythe inner pinion 44. thev teeth of which mesh with the teeth 43 upon thelpulley'42.' The pinion 44 is rigidly secured upon an upper shaft 45, journaled in the main brackets 40 and 41,by means of a set'- screw 44fl or otherwise, and is adapted to rotate with said upper shaft 45.

'Io'impart motion to the upper shaft 45, I provide a vertically-disposed worm-shaft 46, one end of which finds a' bearing in the arm 47, projecting laterally from the inainJ bracket 40, the opposite end being seated in a projection 12c.upon the upper side of the lower 'bracket 1 2. The said Worm-shaft 46 is driven by the bevel-gear 48 on the driving-shaft 1l and the bevel-gear 49 on the vertical wormshaft 46. Adjustably secured by set-screw 5()a upon the worm-shaft 46 is a worm 50, which meshes with the worm-gear 51, keyed or otherwise rigidly secured to one end of a short shaft 52, carried by an adjustable-bracket or bearing 53, secured to the main bracket 40 by means of a bolt 54, the slot 55, into which the bolt'extends, being elongated for a purpose `hereinafter set forth. On the opposite end of the Shaft 52 from that occupied by the wormgear 51 Idisposea'pinion 56, which meshes a lpinion 57, mounted upon the shaft 45, the said pinions 56.and 57 being changeable, so that rwhen it is desired to regulatethe speed of the pulley 42 pinions of different sizes are placed upon .the shafts 45 and 52,.thus varying the -speed of said pulley.

I secure upon tbe upper end of.

'56 .and the'worm-gear 51, may be'adjustedup or down to compensate forthe different-sized piions that may be used, thus avoiding the necessity of using intermediate pinions'in orderA to provide'the desired' speed. It will be obvious that when the bearing'53-is raised or lowered the worm'50 may be correspondingly raised or lowered upon the Worin-shaft 46.

It being very desirable and important that themachine shall be quickly stopped when one'of the threads becomes broken, I have -respectively. A portion of the upper lever is bent downwardly to provide a linger 62, which is slightly tapered, so as to pass freely between the lever-plate 58 and-a locking-,bar

63, which issupported on pin 67. Thelower trip-leverl' bent upwardly to provide a linger 64, which is also preferably slightly tapered to 'fit between thesaid plate 58 and the locking-bar 63. Pivotally mounted upon each y provided for the accomplishment of this result ofthecarriers 16 by means of screws 65L are tripping devices-65, limited in their movement by means ofthe screws 65b 0r thelike. The tripping devices 65 carry pins 66, upon which the threads bear and th row the tripping devices Iinward'untiltheir inner ends come in contact with the screws65b or the like, which act as stops. When one of the threads from the upper bobbins becomes broken, its trip will be thrown out by centrifugal force and bear .against its screw 65b and 'bring its pin 66 into the path of the upper trip-lever 6() and striking the latter will cause theiinger 62 to swing outward and push the locking-bar 63 off its supporting-pin 67 and re'leaseit, so as to permit the combined belt-siii fters and brake mechanisin to operate. l

In order to detect or locate a break in ythe threads from the lower bobbins, I have yprovided slotted studs 68, mounted at suitable points around the periphery of the spider 7, the said studs carrying tripping-pawls 69, pivoted thereto, on which the lower threads bear to hold them inward,'but adapted to swing outward by centrifugal force when the thread bearing thereon is broken,. the released pawl moving out in the path of and engaging ,with the lever .61thus causing the finger' 64 of thel latter to swing outward and disengage the bar 63 from the pin 67, the bar 63 being su iliciently yielding tothus move on its pivoted connection hereinafter described. Afterthe respective tripping devices have passed. beyond the tripping-levers 66 and 6l the said levers are restored to their normal positions by suitable By providing the elongated slot 55 in theA bracket 40 the bearing 53, carrying the pinion springs 7.0 and 71, respectively. The locking-bar 'is held ina position relative -to the IIO the pin 67 by means oi' a retaining-staple 72 or the like, in which it is Jfree to move outwardly and slide when released. Pivotally attached to one side of a suitable standard or basemem* ber 73 is a bell-crank lever 7%, to the long arm 75 of which is pivotallysecured, about midway of the length thereof, oneend ot' the loelriugdiar 63, the short arm76 olf the bell-cranl lever 7i carrying' one end of a friction-ineke 77, the said riction-ln'alie beinp,` secured to any suit- .able stationary object at its other end, so that when the locking-bar 63 is disengaged from the pin 67, so as to slide in the staple 72 or the like, the friction-brake 77 will be drawn down into the channel 78 otl the brake-wheel i5 by means ot' a spring 79, secured to the short arm of the bell-crank lever, thus quickly checking' the speed of the machine, inasmuch as the belt has at the sanneV time been shifted 'from the driving-pulley 13 to the idler i4.

Mounted upon the upper portion oi the standard 7 by a pivot-bolt 8(lis a bifurcated belt-shifter 80, having' a. lz'iterally-extending arm 81 arranged so as to be engao'ed b v the long arm 7-5 ot the bell-crank lever :4. When the locking-bar has been disengaged from the pin 67 andthe bell-crank lever 74 released and its long' arm 7 5 has been thrown forwarth a spring 82, secured to the standard 73, is re leased from compression and forces the belt shifter outwardly, thus transferring the belt Jfrom the dliving-pulleyv i3 to theI idler ill# and causing; the 'machine to stop running. The belt-shifter 8O is held in the position shown b v dotted lines in Fig. .5 bi; the spring S2 un tilthe bell-crank lever 74e is drawn back to its upright position, the arm 81 being' in the path of theosaid bell-crank lever, causing; the beitshil'ter to assume the position shown in i'ull lines in Fig'. 5, thus transferring the belt irom the idler let tothe drivi:ng-pullerv 12% and again starting the macaine. the belt shiited from the pulley to the idler, or vice versa, the brake is applied or released.

it very frequently becomes desirable to release the Jf'rictimi-ln'ale '77, so that the-machinev maybe manuali)7 operated for the purposlenoi' adjustment; and it is therefore necessary to avoid shifting the belt from the 'idler to the driving-pulley, vand to this end l provide two holes or seats S3 and Se in the locking-bar 63, so thatshould it be desirable to release thefriction-brake without shifting the belt the bell-crank lever 7.4 is drawn back until the inner hole or seat 83 registers with and receives the` pin 67, the'arm S1 ol" the belt-shifter 8() only just coming in contact with the said bell-crank lever 7st at .this position. lt'will thus be seen that the belt-shifter and friction-brake may be operated independently oi each other. i

When itis' desired to throw the belt into.

operative position and also release the frictionit wiil he seen that as.

l brake, the bell-crank lever 7a moved on un .1 'til the pin (i7 registers with the hole 84.

rllo

give a V mer grip u ion the channeled pulley il s pr ide a shoe upon thc standard 73 in instap sition to the under side o'r' the channc-l 7n of? the pullewY l5, so that when the frictionbraid- 77 is applied the pulley 15 is caused to slightly yield and come in contact with and bcaragainst the shoe by the nction oi' the bell-crank lever, thus providing additional frietionsurface, and inasmuch as tue pulley 15 is practically surrounded by the `gripping' members the machine is quickly stopped when the friction-ineke is applied.

ln operation the threads/funn th'e upper bobbins 30 are passed through the inner eyes 8G" of thoarins STG, which are secured to the carriers 16, thence mtwardlv to the eyes 87, also secured to the carriers iti, thence around the tensions Sli, mounted on the carriers 16. passing thence to the outerside of the pins 613 on the upper tripping devices (S5 on the carriers lo through the eyes 89, also on the carriers i6, and then to the ln'aidii1g-pointwhere the threads are incorporated or plaited around the core, which extends up through the tubular guide 36. The threads from the lower bobbins 29 are first passed through eyes 90, secured upon the periphery of the spider 7, thence around the tensions 9i, also secured to the spider 7, passing to the outside oi the pivote-.d pawlslli), to the eyes 911, and $1.6. over the branch and terminal Elli to the guides 97 on the lover 98 of the thread-direel.- ing gear 27.

lt will be clearl)- obvious that b v having the threads so disposed with respect to the tripping devices 65 and the pivoted pawls (il) the threads traveling' thereon will ol' their own tension hold the tripping devices nl) and pivoted pawls (it) inward, so as not to come in contact with or engage thc trip-levers (30 and Si, respectively, until the threads are broken, when they will instantly ily or be thrown outward by centrifugal Jforce into the path ol' and oinfrate the saidtrip-levers.
