ings, for forming a bunch on the base of the bobbin for cooperation with the feeler of automatic replenishing looms, and involves simple and easily manipulated means for setting the machine so that it will operate either to produce a bunch wind on the bobbin or a smooth lay thereon, as may be preferred. The invention also comprises the specific means above referred to in combination With certain other parts of the mechanism as will be hereinafter made apparent and as will be more particularly pointed out in the accompanying claims.

In the two sheets of drawings'forming part hereof,

Figure 1 is a front elevation of so much of an ordinary ring spinning frame, with parts in section, as will be necessary to illustrate the application of the invention thereto, it being understood that the invention is also applicable to analogous lands of textile machinery.

Fig. 2 is an enlarged detail in longitudinal section of the pulley cradle and its bracket support.

Fig. 3 is a top plan thereof.

Fig. 4 is a side elevation of the same viewed from the opposite side of the machine as shown in Fig. 1.

Fig. 5 is a detail on a still larger scale, of the pulley or rotary guide.

Fig. 6 is a detail of the filler thereof; and

Fig. 7 is a section of the pulley showing the means whereby the filler is secured thereto.

The numeral 1 represents the end standard of the spinning frame, 2 the usual bolster beam thereof bearing the spindles 3, and 1 represents the ring rail which is carried on rods 5, the latter being operated by the lifter Specification of Letters Patent.

levers 6, as will be well understood by those familiar with this subject. The lifter levers 6 are connected through their sector arms 7, and a chain or like flexible connection, with the builder motion 8, which may be of any usual construction and ordinarily involves a builder lever pivoted on a stud 9 on the end upright 1, such lever receiving an up and down motion from a builder cam 10, and its chain connections receiving an additional gain movement through the cooperation of its ratchet wheel with a suitable pawl, as indicated in a general Way in Fig. 1. The specific construction of the builder mechanism forms no part of the present invention and detailed description thereof will not therefore be necessary. It will of course be understood that its function is to impart its oscillating movement through the lifter levers 6, and lifter rods 5, to the ring rail 4:, so as to lay the yarn on the bobbin in any particular form of Wind that may be desired.

The means whereby the oscillating movement of the builder mechanism transmits its movement to the sector arms 7 of the builder levers, comprises a chain 11 con nected to the said oscillating lever and extending upwardly therefrom to a guide-pulley 12, to which the end of the chain is secured, as indicated at 11 in Fig. 2. This guide pulley is a double tread wheel or sheave journaled on an axle 13, which axle is carried in a cradle 14:, and the cradle 14 is mounted so that it may rotate on its longitudinal or horizontal axis in a gooseneck bracket 15, secured to the upright 1 directly above the builder lever. As the builder lever oscillates on its horizontal stud 9, the angle of the stretch of chain 11 changes more or less from the vertical and the rotary mounting of the cradle and its guide pulley serves to accommodate such change, so that the chain 11 will at all times be perpendicular to the axis or axle 13 of the rotary guide pulley, substantially in the manner shown and described in Patent No. 677,791, dated July 2, 1901. The remaining portion of the flexible connection from the builder lever to the sector arm 7, comprises a stretch of chain 16 connected at one end to the said sector lever and at the other end with the opposite tread of the rotary guide pulley, a

swivel 17 being included in the stretch to accommodate the swiveling action of the cradle and guide above referred to. The chain 11 in the present instance is secured to the tread of the guide pulley which is toward the front of the machine as viewed in Fig. 1 and marked 12*. and the chain 17 is secured to the tread 12" in rear thereof, in such manner that the unwinding of the chain from one tread produces the wind of the chain on the other tread,and vice versa.

The two treads are desirably separated by a rim 'fiange'12", and their chains are confined thereon'by means of side flanges 12 and 12*, respectively. The chains will thus be confined properly to the guide pulley when they are slack, as a doffing, notwithstanding the angular position which the guide pulley may hold in itsbracket 15 at the time.

'In'norma-l operation the function of the guide pulley is first to change the direction of the up and down motion of the builder lever into horizontal motion'of the chain 16 and the sector arms, and,sec-ond, to modify suchmotion at the initial stage of the building action so .asto "affect the lay of the yarn upon the bobbin and produce a bunch thereon such as will be suitable for, cooperation with the 'feeler of automatic looms, or for any other purpose that may be desired. To

this end the tread 12 is mutilated or distorted, as, for example, by removing a segment thereof, as indicated in Fig. 5, leaving a flat surface'18 thereon, which is so located as to be in contact with the chain 16 at the beginning of'the winding action. This irregularity in the otherwise cylindrical surface of the pulley tread produces a relative dwell in the action of the chain 16 and the parts which lift the ring rail, so that the desired bunch is formed near the base of the bobbin, but as the range of the traverse progresses toward the tip of the bobbin, gradually'revolves to a position where it will be out of contact with the chain and'ineffective thereon, so that after the bunch'has been formed the rest of the bobbin will be built with such wind as may be determined by the characteristics of the builder mechanism 8. When it is desired to build a smooth lay on the bobbin, as, for instance, when changing over to spin a warp yarn, the tread surface 12* of the guide pulley is restored to its cylindrical contour by inserting or replacing a removable part or segment, such as shown at 19 in Figs. 6 and 7 This attachment can be bolted to the body of the pulley by means of a bolt 20, as shown, and

is provided with a rim flange 19 which is contlnuously circular with the r1m flange 1%,

so as in effectto provide a plain circular tread for the chain 16. It will be observed, more particularly in Fig. 41, that the struc ture of the cradle 14, is such as to permit access to the head of the bolt 20, without removing the guide pulley therefrom, so that changing over from a bunch to a smooth wind, or vice versa, can be accomplished without inconvenience or complication.

By forming the guide pulley as a compound or double tread wheel, it may be as small as desired and yet bear a suflicient length of the chain 11 lapped thereon to accommodate the full traverse and 'gainmovements necessary, but if size is not regarded as of consequence, the pulley may be a single tread pulley and the chains 16 and 11 a single stretch of chain. In'such' case the single tread will be interrupted in the 'same manner, as above described, to produce a dwell'of the traverse motion at'theproper point and siippliedwith a removable .and replaceable filler segment such as shown in Fig. 6,"for changing over'to a smooth lay. The function and mode of operation of the distorted tread and its removable attachment will then of course be the same-as in the case above specifically described and shown in the drawings. It will beunderstood by those skilled in this 'art that the mechanism above described is notlimited in respect of the details'of its mechanical assemblage or construction, except as-expressl'y specified in the claims hereto,"and that various omis sions, alterations and reversals may be resorted to without departing from the invention.
