l Application filed January 24, 1882. -(No model.) Patented in England July1 11, 1882, No. 3,288.

To all ywhom rt may concern:

Be it known that we, FLORENCE L. VEERn KAMP, CHARLES F. LEOPOLD, and WILLIAM DARKER, citizens of' the United States, resid- 5 ing in the city 'of Philadelphia, in the State of Pennsylvania, have jointly invented certain new and useful Improvements in Braiding- Machines, ot' which the following isa specifi; cation.

Our invention relates to improvements in rotary braiding-machines in which two sets ot' bobbins movein contrary directions inconcentric annular paths, as described in Letters Patent of the United States granted to F. L. Veer- 15 kamp and C. F.Leopold,No.56,6at3, dated July 24, 1866; and our improvements consist in mechanism hereinafter described, whereby we are enabled to dispense with many features of the old machine and attain a greater speed in 2o operating the same and produce a larger productin agiven time; in mechanism which greatlydiminishestheliabilityto break threads, and

inthe several parts of the machine, more especially the carrier-bearer for sustaining and 25 conducting the carriers and bobbins around the machine, the grooved ring in which the carriers move, the guiding` mechanism for directing the course ot' the, threads and interlocking` the same, the tension mechanism for taking up 3o slack thread, the devices for stopping the op. eration ot the machine when a thread breaks or runs oli' the bobbin, and in the construction of the bobbin-carriers. In thetormer machine, referred to, the threads ot' the outer and lower 3 5 bobbins were caused to pass to one side and then to the other of the inner and upper shut ytles by means of curved wires or projections on a cani-plate which pushed the threads outward, whileweights and springs, which formed 4o a part of a tension device, applied to each ot the threads from the lower bobbins operated to draw the threads inward into recesses in a circular plate which supported and carried the lower bobbins, the action ot" these parts caus- 45 ing the lower threads to pass alternately from one side to the other of each of the upper thread-carrying shuttles, each ot' which was separately moved or' pushed in a groove in a circular plate aixed to the driving mechanlarge number of upper threads from bobbins supported in carriers or holders whichare not in themselves movable, but each and all held in a single movable carrier-bearer, which consists of a tlat circular plate secured to and re rolved by a central shaft, and the outer edges ofthe bobbin-carriers move in a groove formed in an annular ring; placed directly above the carrier-bearer, said ring being,` supported and revolved by means ot' uprights secured to the rim of a skeleton plate, T, hereinafter described,

attached to a revolving sleeve covering the inner tubular shat't referred to, and the arms of which skeleton plate support the lower bobbins, and to the rim thereof are secured tension-springs for the lower threads. The rim of a stationaryv plate supported from the cen ter ot' the machine supports guide-arms, over which the lower threads are drawn and guided `lo f means of ushironO-s or threadcarr 'in l e g guides secured to the rim ot' the grooved annular ring` above the carrier-bearer.. Thus the carrier-bearer being revolved in one direction by means ot' the tubular shaft, and the lower bobbin-holder, with the grooved ring and its thread-carrying guides, being,` revolved in an opposite direction by means ot the revolvingl sleeve, both by appropriate driving mechanismthe upper and lower. threads are by these means crossed, interlocked, and platted to form a cord or braid without any separate movement ot each upper bobbin-carrier, or any separate movement of each thread-guiding device, the said bobbin-carriers and said thread-carrying guides being stationary on the carrier-bearer and ring, respectively, which latter alone are revolved or'moved in the manner described, which, in connection with the tired guide-arms above referred to, causes the lower threads to pass alternately over and underrthe bobbincarriers which supply the upper threads.

In order to enable others skilled in the art to make andnse our inventiomwe will proceed to more particularly describe its construction and operation, reference being had to the accompanying drawings, in which Figure I is a front elevation ofthe machine with a part broken away; Fig. II, a sectional view thereof; Fig.III,a topviewthereof; Figs. IV, V, VI, and Vll, views of the upper bobbin and carrier; and Fig. II, a section of the grooved ring Iand its bolt r, showing the vertical edge ofthe bobbin-carrier.

Similar letters refer to like parts throughout the several views.

The frame-work of the machine consists of the base A, having in its center a hollow cylindrical projection or upright tube, a, on the outside of which is placed a revolving sleeve, I), and through bothsleeve and projection eX- tends a tubular shaft, B, at the upper end of which is placed or secured a small disk, C, for the purpose of supporting the inner ends or steius ofthe carriers c, the outer ends of which rest edgewise ou the rim of the carrier-bearer E in recesses c', made at suitable intervals therein. From the base of the machine arise two uprights, F F, with a cross-arru,G,to connect them and hold `the take-up device R.

The machine is driven by a main shaft, 2, having on its inner end a bevel-gear wheel, 3, working into a bevel-gear wheel, 4., secured to the revolving sleeve Z), and the inner tubular shaft-,13, is operated by means of a bevel-gear, 5, connecting it with the gear 3 on the main shaft.

rIhe carrier-bearer E is secured to the tubular shaft B, and consists ot' allat circular plate, above which isv placed a grooved ring, L, supported by uprights 6` from and carried around by the rim ofthe skeleton plate T, the spokes t of which sustain the lower bobbins. The upper sides'of the vertical edges of the carriers o revolve in the groove ot' the ring L, to which latter are secured push-prongs d, set at proper intervals for directing the course of the lower threads up and over the guide-arms M, and over and under the carriers alternately. The grooved ringL is slotted alongside of each push-prong, and into the slots the lower threads slide to enable them to pass over the bobbin-carriers. The lower threads are guided above and below the upper bobbins alter- `nately by means of stationary horizontal guidearms M, constructed as shown in Fig. I, secured to the rim of an'annular plate, a', which is bolted to the hollow upright tube or pro- 6o jection a, (see Fig. 11,) the plate and hollow tube being immovable and stationary. Each of the lower threads, which are held taut by their respective tension-springs N, hereinafter mentioned, first presses against the lower end of one ofthe guide-arms M, thus enabling it to pass under one of ythe bobbin-carriers c, af-

ter which itis-then carried Aby'ay push-prong II) and stop the machine.

d up and over the upper end of the guide-arm M into one ot' the slots 7 in the grooved ring L, and thus passes over the next bobbin-carrier, and so on alternately.

Io the revolving sleeve b is secured the aunular skeleton plate T, Vhaving the spokes t, supporting the rods upon which the lower bobbins, H, are placed. Tension-springs h pressing against the bobbins prevent them from delivering the thread too freely as the bobbins move around. Other tension-springs, N, secured to thc outer edge of the rim I of the bobbin-holder, have each an eye, 8, at the extreme end, through which the' thread from a lower bobbin passes, and serve to hold the thread taut on the guide-arms M and take up any slack. Said threads, after passing through the guide-eye I4, and before reaching the eye 8 of the spring N,pass under and sustain droppers p, which, when a lower thread breaks or runs off the bobbin, fall and strike an arm, o, on the-upright rod K, which throws the machine out of gear and stops its operation, as hereinafter described. The carrier-bearer E has suitable recesses and abutments, c,to keep the carriers c a proper distance from each other, and also bars 9 (see Fig. Il.) to sustain them radially.

The bobbin-carriers c are constructed, as shown iu Figs.Vand VI, with a vertical edge, a, which moves in the groove ofthe ring L, a shield, y, over and under which the lower threads pass alternately, a tension-spring, r, adapted to bear against the thread on the bobbin, and a stopper-rod, fw, which radiates from the center of the machine, and has its outer end supported vin an opening, 10, (see. Figs. III, IV, and V,) in the vertical edge u. 'Ihe stopper-rod te, on and near Ii ts inner end, is provided with an eye, 13, through which the thread from the bobbin passes, and when a thread breaks or runs off the bobbin the said rod, which plays loosely in the hook 12, (see Figs. III and V,) is set free, and by centrifugal force is thrown out through the opening I() sutiiciently far to strike the lower beveled end of the bolt r and elevate it enough to hit the latch s on the upright rod K (see Figs. I and This bolt r is beveled at its lower end, as shown in Fig. IIe, and works freely up and down in asuitable recess on the outer surface of the grooved ring L, and a dat spring (shown in dotted lines in Fig.

Ile) keeps the bolt r elevated after having beeir raised by the stopper-rod fw; or, as shown in Fig. II, the grooved ring niaybeslotted perpendicular-ly to receive the vertical bolt r, which latter is slotted in the part which is within the slot of the grooved ring, and is supported by a set-screw passing through the grooved ring and through the slot of the bolt. 'Ihus when the bolt r is elevated by the stopper-rod w it will be kept elevated by its frictional contact with the adjoining parts, and will engage with the arm s of the stopping mechanism on 4coming around to the same. The rod K revolves looselyin a slot in the base IOO IlO

eva/.52s 4 3 of the machine, and has affixed to it by a setscrew a sleeve provided with a cam, Y, which cam,when the rod K is moved,operates to unhook the rod X, connected with the lever Z, which, when released, is operated, by means of the spring X', to shift the driving-belt from the tight pulley to the loose one.

The upper bobbins, W', (shown in Figs. lV and VIL) are made of any suitable metal, and are formed convex to give strength, and to aid in shedding the lower threads as the latter pass over and under the carriers alternately. It is essential that they should be of the form shown. The heads of the bobbins are each spun with a sleeve inthe center, one slipping over the other and forming the barrel, a suitable wooden hub being inserted.

The operation ot' the machine is as follows: Motion being given by means ot' the drivingshaft, thelower bobbin-holder, with its bobbins, moves in a circle, and the carrier-bearer, with `its carriers and bobbins, in a contrary direction. The threads from the lower bobbins are directed by the push-prongs along underneath the carriers, then up and along the guide-arms and over the next carriers, thus causing each of the lower threads to pass alternately over and under the upper bobbins and carriers, interlocking the threads and producing the braided cord, which is drawn up through a suitable guide-by the take-up device R, located over the central disk. i

It is apparent that the number of upper and lower bobbins may be increased or diminished, and that the construction and arrangement of many ofthe parts may be varied without departing from the main features of the invention. In our improved machine, herein described, the movements of necessary parts and theconsequent wear and tear thereof are reduced to a minimum and excessive friction,

thereby avoided, and the machine can be run at a high velocity, producing a greatly-increased product in a given time as compared with former machines.

Having thus described our invention, what we claim as new, and desire to secure by Let` ters Patent, is-

1. rlhe combination, in a braiding-machine, of a set of upper bobbin-carriers, a revolving carrier-bearer, and devices for supporting a set of lower bobbins, with mechanism for revolving. the carrier-bearer'and lower bobbinholder in contrary directions from each other in concentric annular paths, but in different planes, stationary or fixed guides, lower threadcarrying guides, and mechanism for supporting and moving the thread-carrying guides, whereby the threads from each of theflower bobbinsv are made to cross alternately over and under 'the threads from each of the upper bobbins and be platted to form cord-braid, substantially as set forth.

2. The carrier-bearer E, with its recesses, abutments, and rim, for holding and carrying the hobbin-carriers c, in combination with said bobbin-carriers, and with mechanism for supporting and revolving the said carrier-bearer, arranged and operating substantially as set forth.
