Bantams-MACHINE.-

United States, and residents of the borough of Wyomissing, in the county of Berks and State of Pennsylvania-,have invented cer-.

tain. new and useful Im rovements in Braidlug-Machines, of wh c reversing means tliei' eforgadaptedfto fpermi the ready convers on of a tubule mtoa-fiat bralden- In tubularfb raiders, where the carriers are constantly traversed in one direction 'by'the series of intcrmeshing drive-gears with their carrier-engaging horns, the race-circles and drive-gears may be made 'um form through out; but where it is requiredfthat the carriers be reversed, as in flat-or plain braiding;

terminal circles and'gears of difierent diameter from those'of the maln'course'arecom- 'monl' 5 employed for the purposecofi chang-' in riers so as to avoid'colhslons.

An important object t is relation of thereversely moving-can vent-ion is that such a change-in the termi nal circles and gears nay-fbe avoided, and that a tuhular machine may' be made readily convertible into a flatbraider-in which" any desired race-circles of the course, with the drive gears therefor, may bemadc toservc as terminals.' 1

' the following is a Y ma'de upoffa circular series of intersecting Pate'nted Dec. 27, 1910.

Or connected.racecircles12, 2?, 2", 23 2, of uniform -'dia1 neter forming normally a con- -=tinuous circular course. In connection with this ordinary race-way are shown means for =-di$connecting certain of the race-circles as desired in carrying-outthe present inventiorn Such means consist, as shown between the race-circlesfl and 2, of an inserted partitidi piecefirfitted between 'the'points 4, 4 ofthezgrooved'bed plate so as to close said race-circles as inthe case of terminal circles;

"or-instead ofthis 'switches maybe provided to' cut'ofi' communication between adjacent circles, as indicated between the race-circles 2" and 2 ,wherc fi indicates a blind switch, and 6 a mechanically operated switch arranged tojbe thrown as required by a suitable-cam 7. 'lllic disk'or quoit' 8 of the regulur c'mlrse cirle inlay he changed to the usnal froimded i'mnib for the terminal cir- "clesf "Itwillhe' undeistood that the circles '2 2 will'be cut out of the flat coursewhen 2 is arranged for use as a terminal in connection with 2*; but that they may be used 'as part of the course by making 2serve' as a'tcrmin'a'l instead (of 2. I As indicated. 'in QFi'g? 2 the ordinary fiat braid course comprises a, series of drivegears 10,10 with, aspecialgcar Ll asa terminal at each end upon whichto reverse the carriers; said gears '10 being. .each proyidcd with] four horns ,as sh oivn and the terminal with {five similar horns iyhile; the relative positions and indicated; movements of the 7 carriers "asguided d nthe different sized race-circles make clear the usual manner of reversingthem without collision In Figs; 3, 4, 5 and-6 ordinary,full-horned drivei-gea'rs w, 10 like those of .Fig. 2, are shown in connection: with a terminal drivegeamlOiwhich is of the samegdiameter as Q the gem-s10 andldiiters from the latter only *in having alternate horns ire novedaso as to of alternate horns as'statc'd, and used in connection with an ordinarv course race-c rcle closed to form a tcrminacircle as indicated in Fig. 1', will operate u )on the carriers in a manner equivalent to -tiat of the ordinary ecial sized terminal circle and its gear 11.

10 5 'i his will be understood by following the re-' ,versin action of. our improved terminal upon t is carriers as diagrammatically illustrated. In Fig. 3.the indicated positions of 5 the bobbin carriers cprres ml with those of .Fig; 2; the carriers 0 an (2 however being located in the clearance-wa s of our improved terminalgear inst of'bei positivel engaged between horns-as in- 1g. 2.

: In. ig. teachof the gears, including the terminal, is representcd'asrotated-a quartet: turn; the effect being that carrier 0 is moved rearwardly by gear 10- and carrier 6 'is swung forward into the terminal race-circle without being engaged between horns of the terminal gear as heretofore, because of its being provided with clearance-way-12 instead of a born." The two carrhrs b and d are thus located inthe sameclearance wa 12,,with the carrier (1 only inpo'sition to positively operated by .the. gear horn,

' while the carrier 0 is in the otherclearance way. -In Fig, 5 another quarter turn of the rs has taken place: The carrier (1 has now. been swung in itsreverse increment to the-junction point of-the circles The car-- ,rier 6 which is refiresefi'ted in this position in I1ig, ,.4 -=--without apparent provision for v.moviiig it therefrom to makeway for the reversed carrier d, is in fact moved onward to approximately the position indicated in Fig.- 5 either by its own momentum, or by the action of'the positively" swun carrier (1 if the momentum alone does not o-it. F ollowing the successive positions of the carriers indicated," it will be noticed that each carrier thus delivered into a clearance-way of our improved terminal gear is so set back by the inctfectiverbtation of the'latter as to secure the required passingsof the terminal race-circle auction without collision.

To provide forfmost jrcadily converting ordinary course drive gears into our terminal gears as desired, the alternate horns 13 of each gear which are to be eliminated,

may be arranged so as to permit of conveniently throwing tliem' nto or out of oper-.

ative position bypivotin'g themv to the body; of the gear as shown at 15, Figs. 7 and fi, and providing spring detents 16 adapted to hold them in either operative onnnppeh ative position as dctermined.. The only other change needed to convert a tubular braiderinto a flatbraidcr, besides providing 55 the dditional bobbin-carrier reqinred as usual, is to insert the partition piece 3 between -thc circles which are to serve as terminals; and this changeina be avoided by iroviding the switches 5 an 6 at such point instead of using the fixed partition piece;

reduced widths, certain of the race-circles may be cut out in like manner, as indicated in Fig. 1; or the full circular course may be divided.into sections so as to provide for producing two or morenarrow braids simultaneously as desired. Thus a sim 1e tubular machine made up of a series 0 uniform diameter race-circles, may be readily adapted to also produce flat braids of any desired widths. What we claim is:'

1. A braiding machine having a. ser es of termeshingfequal-sized driveears therefor alternate hornsv removed and serve as terminals. 2. A braiding machine having a carrier drive-gears, and an intermesliing .terminal drive-gear of .iike diameter having two oppositehorns' only and. intervening carrier clearance-ways whereby it is adapted to tially asset forth; 3. A braiding machine drive-gear. having a pivotally mounted carrier-engaging horn and means for locking the same in operative or inoperative positions.

4. A braiding machine terminal driveear having a series of fixed carrier-engaging horns and intermediate pivotally mounted horns with means for locking the same in operative or inoperative positions. v

- A- braiding machine having a raceway formed by connected aace-circlcs, means for separating certain of said racecircles to form'terininal-circles; a. seriesof full-horned carrier drivegcars for the comv nccting race-circles, and intermeshing terminal drive-gears of the same diameter for said terminal circles having alternate car rier-engaging horns removed to form car- "rier clearanc sways.
