To all whom, it may concern.'

Be it known that I, ALPHONSE Bro, of the city of Roubaix, Department of the North, France, have invented new and useful Improvements in DoublingWinding Machines, (for which I have obtained a patent in France, No. 156,386, dated July 2, 1883; in Belgium, No. 62,117, dated July 24, 1883; in England, No. 3,808, dated August 2, 1883; in Germany, No. 27,526, dated August 9, 1883; in Austria- Hungary, No. 47,393 and No. 10,009, dated March 11, 1884; in France, No. 161,396, dated April 7, 1884; n England, No. 7,035, dated April 30, 1884, and in Belgium, No. 65,152, dated May 6, 1884,) of which the following is a full, clear, and exact description, reference being had to the accompanying drawings thereof,

` in which- Figure 1 represents a face view of a portion of a machine for six yarns. Fig. 1 is a detail, hereinafter referred to; Fig. 2, an end view of the machine; Fig. 3, a section looking toward the stop-motion lever. Fig. 4 shows a diagram of the position of the parts when the machine is working normally; Fig. 5, a similar View showing the position of the parts when the stop-motion comes into operation on the breaking of the yarn.` Fig. 6 is a side elevation of the lever 7.1. Fig. 7 is a plan thereof. Fig. S is a view of the frame or bracket f detached. Fig. 9 shows one of the pivoted thread-guides and its weight. Fig. 10 is a detail view, to be hereinafter referred to; and Fig. 11 is a view of the stop-bar y.

The same letters of reference indicate like parts in all the ligures.

A represents the frame of the machine, and a are the bobbins mounted on the upper part thereof, as shown in Figs. 1, 2, 3. The yarn suppliedfrom bobbins c passes through the fixed guides b, secured to a cross-piece below the bobbins, around the outer side of a roller, c, havingaroughened surface, to cause the th reads to bind slightly and cause a tension. Some force will be required to turn the roller, and hence the thread causing it to turn will be under tension in proportion. The axis of tension-roller c is aspindle, d, screwed at one end into a cheek-plate or arm, e, carried upon the l that the point at which the yarns leave roller c, the point at which they touch rod g, and the eye of yarn-guide h (to be presently described) shall be in a straight line. rlhe frame or bracketfis pivoted at t' upon the frame below the iixed guides Z), to swing freely on the breaking of a yarn, as hereinafter described,

but so as to always hang in the position shown in Figs. 2, 3, and 4 in the normal operation of the machine.

The spindle 71?, upon which oscillate the counterbalanced yarn-guides h., is mounted in t-he arms ffz ofthe frame or bracketf above and in front of the axis ,so that on the breaking of a yarn the axis of the yarn-guides, and consequently the guides themselves,(see Figs. 4 and 5,) swing upward, the said guides contacting with a stop-bar, y, (to be hereinafter described,) which throws their eyes toward the attendant, whereby the yarns may be readily pieced up. r1`hese yarnguides are mounted between their ends on the spindle h2, and their inner ends are provided with the depending weight h', while their outer ends have eyes h, one such guide being provided for each yarn or thread.

From the upper curved end of the upward and inward curved arm f of the bracket f a weight, j, is suspended by a chain, j, said weight being also connected at its bottom end to the stop-motion lever 7c, to be presently described, by a chain,whose length is regulated by a nut, j', on the weight and a screw-eye on the upper end of the chain. To the lower end of the frainef, in front of its axis, isjoint-ed the rod Z, which operates a brake (to be hereinafter described) for the purpose of arresting the spool.

o is a shaft provided with blades, and is journaled in slots in the main frame below and parallel with the axis of frame f. The shaft may be adjusted more or less closely to the lower edge of frame of bracketf to properly strike the same, and has a pulley (see Fig. l) for rotating it. This adjustment of the shaft o may be accomplished in any well-known manner-for instance, by mounting it in sliding bearings o', operated by setscrews 0".

The winding bobbin or spool m is mounted between the arms of a. vertically-swinging frame, p, hinged to the lower rail, 9, of the machine-frame, so as to allow of the bobbin or spool rising as its diameter increases.

p2 is a stud on one side of frame p, which is adjustable in a slot, p3, in said frame and fixed by a nut. Below the swinging frame p and parallel therewith a bracket, i', is secured to a cross-piece, s, of the frame A.

7c is the brakeeoperating bell-crank lever pivoted at its angle to the bracket r to swing vertically, the inner end of its long arm being weighted as at 7c3 and connected to the chain below the weight j.

In the normal working of the machine the vertical forward side of the stud p2 bears against the face 7cL of the short arm of the weighted lever k, which is curved to an arc of a circle described from the pivot of frame p as a center. (See Figs. 3 and 6.) Contact ofthe two parts p2 7c* is insured by regulating the tension of the lower chain of weight j by means of nut j and the' screw-eye. The weighted end of the lever 7c will keep it in po sition by causing the curved face 7c3 to bear against the stud p2. The object of the curved face k* of the lever 7c is to prevent the constantlyincreasing size of the bobbin producing any effectupon the frame 'for the weighted threadguides. The weighted lever k also carries the guide-rod k, extending across the under side of the framep, and beneath which the doubled yarn passes to the winding-bobbin, said rod being so arranged with reference to the pivot of lever 7c that on the stopmotion coming into action it will be carried inwardly or toward the frame as the frame p is swung upwardly, so as to allow room for the attendant to introduce her hand. k guides the doubled threads to the guide n, hereinafter described. When the bobbin or spool has attained the desired size, the stud p2, which rises with the frame p, will passbeyond the curved face c of the lever 7c and rest upon the incline 7a2, thereby allowing the weighted end to fall. (See dotted lines, Fig. 5.) To the bracket o' is pivoted a bell-crank lever, t, carrying the leather tongue or brake t', which is to be inserted between the bobbin and its friction-drum n for stopping the motion. The lever t is connected to the lower end of the rod l and operated thereby, and the yarn is led from the rod 7c through a small guide, a2, (see Fig. 1%) soldered or otherwise attached to a rod, u, working in guides u on the outer end ofthe frame r, and receiving to-and-fro motionfrom a cam, u, in the groove 0f which This rodv runs a pin on the carrier, (not shown,) to` which the end of the reciprocating rod u' is fixed, as will be readily understood. yThis guide u2 is open at its top; but the rod 7c', un der which the threads pass, holds them down and prevents their disengagement from said guide, except when the rod and framep are swung, respectively, inwardly and upwardly. The cam u3 has a gear, u, with which meshes a gear, n2, on the shaft of the frictiondrum n.

y is an adjustable stop-bar secured to the frame A, behind the bracketf and projecting therethrough above the axes of the thread@ guides l1.. The stop-bar y has slots y in the inner ends of its arms, and set screws 'y2 pass therethrough into a part of the main frame. A U-shaped cross-wire, e, fixed by its downwardly-bent ends in holes in a rail, n', secured to the frame A in front of the bracket or frame f, serves to hold down those guides 7L which ,are not in use and which aet as a support for those which are in use, the former being below and the latter above it.

The opera-tion of the machine is as follows: rllhe yarn or threads pass from the bobbins a down through the guides b, over the front of roller c, under the rod g, through the eyes of the pivotal thread-guides h, thence under the bar or rod 7c', through the guide a", to the winding-bobbin. Thelower chain of weight,j,isin tension, but has no strain on it, (the weight ot' the weighted end of lever 7c being sustained by stud 192,) so as to be in readiness to actuate the stop-motion immediately a yarn breaks. The weightj and rod lare thus in equilibrium during the normal working of the machine, as shown in Fig. '3. When a yarn breaks, the counter-weight h of its guide h descends into the path of the revolving blades on shaft o, which strike it, forcing it against the lower end of the bracket or framef, thereby throwing the lower end of the bracket outward and upward and its armsffl and roller c inward and causing the leather tongue or brake to be advanced between the bobbin and the frictiondrum through the medium of rod Z and bellcrank lever t, thus arresting the bobbin. The weight j at same time drops slightly and slaekens the lower chain, so that immediately the bobbin-holder is raised on its pivotp by the attendant lifting the projection x the lever 7c falls, bringing the incline k2 at the top of its short arm beneath the stud p2, and thereby holding the bobbin raised. The lever in falling also puts the lower chain, j, vin tension. The brake is also applied whenever the framep is swung up a suflicient distance to disconnect the stud p2 from the incline k2, as the weighted end of said lever will then drop, and, through the medium of the weighty', connection j', frame f, rod Z, and lever t, throw forward the tongue t.

The combined effect of raising the axis of the yarn-guides h by the oscillation of frame or bracket f and. their arrest at the same level by the adjustable stop-bar y is to throw their eyes well forward within reach of the attendant, so,

. ef- V as to render easy the piecing up of the yarn. The guides strike the stop-bar y just in front of their pivotal points h2, so that their eyes or outer' ends cannot be swung too far inward,but are thrown forward within reach of the attendant, as just stated. The oscillation of the bracket or framef also causes the yarn-guides h to bear against the fixed bar y, while their center is displaced and occupies the position seen in Fig. 5, thus raising their balanceweight h sufficiently to move them out of the path of blades o.

To restart the machine,it is simply necessary to pull the tension-roller c forward by the prorg jecting end of its spindle, thus releasing the brake-tongue, putting the weighted chain j again in tension and raising weighted end of lever 7s, thus throwing its end 7a2 from under the stud p2, by which the bobbin-holder is supported, and allowing the bobbin to again resume contact with its friction drum and recommence the winding. I have described but one set of the above mechanisms, (though the drawings show the frame A carrying two sets,) as both are exactly alike.
