Thegrail or support l5i carr'ies a builderscrew 23 which rises fixedly therefrom. Fitted to turn slightly 'on' the screw 23 and to slide longitudifnally thereon is a sleeve 24 on which'a nut gear 25'is rotatably mounted; The gear 25 has aplate or a m 26 engage'dwith the thread ofthe screw 23 'tocause upward movement of the nut gear 25 an'd sleeve 24 when't'ne gear is turned in the direction of the arrow. inFig. 3. One end of the plate'25 is pivoted, at 27, to the gear 25, and the other ,end of the plate 26 isheld normally in engagement with th'escrew 23 by a spring. 28 conn'ecting the plate and-gear25. A fterfmovin g the t arm 26 gfrom-engagement' with the screw 23 the The sleeve 24 forms the fulcrum part of a yarn guiding arm or lever 29 having arms 30 and 31 projecting from the sleeve 24. The free end portion of the arm 30 has a bracket 32 adjustably secured thereto carrying ayarn guide 33 for directing yarn to the cone 8; carried by the spindle 4. This guide 33 may be of any approved form. As herein illustratedit comprises two parallelbars 34 secured to and projecting from the bracket 32 and forming a yarn passage .35 between them. The bracket 32 is provided with a round bar 36 which projects therefrom outwardlyof and parallel to the bars 33, and the yarn 37 passes beneath the bar 36 before entering the yarn passage 35. This bar 36 may be formed of glass or other suitable wear resisting material. v

The strand of thread or yarn 37 is drawn downwardly to and then beneath the bar 36 to the cone 8.

Any suitable devices may be employed to support the yarn 37 at the source of supply thereof and guide it therefrom downwardly to the bar 36 and yarn guide 33, such,'for example as the devices shown and described in Patent No. 1,6'76,

374, dated July 10, 1923.

The operation of winding the yarn 37 upon'the cone 8 draws the yarn guide 33 and lever arm 30 toward the cone 3, and the movement'thereof inthat direction is limited by the engagement of a bracket 38, secured on the arm 31 of the lever 29, with the surface 39 of a vertically extending cam 40; This cam 40 has a sleeve or collar 41 thereon which is slidably fitted to a flat, vertically arranged bar 42 the lower end of which is secured toa bracket 43 which is secured upon the frame'bar 3. The collar 41' and therewith the cam 40 are vertically movable on the bar 42,

and the collar 41 is provided with a flat friction spring 44 which bears against one side of the bar 42to support the cam 40inthe different positions to which it is moved on the barj42, as

'will be hereinafter explained. I

The camsurface 39 is set at an incline with relation to the axis of rotation of the spindle 4 so that,during the raising and loweringof the frame 14, the pull of the yarn 37 against the yarn guiding bar 36 will hold the bracket 38 against the cam surface 39 and that such surface will the spindle during the downward movement ofthe frame 14 for a purpose hereinafter explained. The length of the cam surface 39 is equal to or slightly greater than the extent of the up and down movements of the frame 14, and the cam 40 is provided with upper and lower projections 45 and 46 at the respective ends of the surface 39. After the lever '29 has been raised on the screw 23 byturningand thereby raising the nut gear 25 on the screw, the bracket 38 is adapted to engage the projection 45 and raise the cam. 40 on the bar 42, to the extent that the lever 29 has been raised on the screw, during the upward movement of the frame 14, and when the nut gear 25 and therewith the lever 29are lowered on the screw23 the bracket 38 isadapted to engage the projection 46 and lower thecam 40 on the bar 42 for purposes hereinafter explained.

Extending parallel to the axis of the screw 23 is a shaft 47 which is adapted to. turn and to slide vertically in abearing formed by the bracket 43. The upper end portion of the shaft 47 has an elongated pinion 48 formed on or secured thereto ing shaft 12 and which turns in bearings on the main frame of the machine.

The shaft 51 is provided with a ratchet wheel 52 adapted to be turned by a pawl 53 pivoted, at

54,130 a collar 55 which is-secured upon one of the rods 16 of the builder frame 14. The pawl 53' moves into engagement with the ratchet wheel 52 by gravity and the pawl engages the ratchet wheel and turns it during each upward stroke of the builder frame 14.

The extent to which the-pawl 53 moves the ratchet wheel 52 during each upward movement of the-builderv frame -14 is governed by a stop screw 56 which is vertically adjustable in a lug on the pawl carrying collar 55. 'The lower end of the screw 56 is directly above an arm 57 on the pawl 53, and, during the upward movement of the builder frame, the screw 56 engages the arm 57and-moves the pawl 53 from operative engagement with the ratchet wheel 52 after the pawl has moved the ratchet wheel a predetermined distance which is governed by the position of adjustment of the screw'56. Each time the builder frame 14 is moved upwardlyduring the reciprocation thereof, the ratchet wheel 52 turns the shaft 51, the gear wheels 49 and 50, the pinion- 48- andthe nut gear 25' to impart the gain movements to the yarn guide 33 carried by the nut gear. r

The whirl disc 9 constitutes a driving element for rotating thes'pindle 4 andthe wheel 11 actuated by the maindriving shaft 12 of the machine constitutes a'driven element for actuating the driving element 9. The lower portion of the spindle 4'is provided with a square collar 58 which is secured thereto and which extends into a corresponding'opening in the whirl disc 9 to cause the rotation of the'spindle with the disc.

The disc 9- has an upward extending sleeve'59 formed thereon and having an annular groove 60 therein providing an annular flange 61 presently referred to. The disc 9 and sleeve 59 are slidable vertically on the spindle 4 and collar 58, and the engagement of the disc with the collar causes the spindle to be rotated with the disc when itis rotated and permits the disc .to be raised and lowered without raising and lowering the spindle. r

At one side of the spindle bearing 5 is an arm 62 the lower end of which is pivoted, at 63; to the bearing '5, and the upper end of which is pivoted, at 64, to an arm or part 65 and also to the upper'end of an arm or link 66. The arm or part 65 extends fowardly from the pivot 64 and has a handle 67 on' the forward 'end' wheel 50- andthe'reby-f stop the rotatiomof the pinion 48 by the gear wheel'50. 1

ward end of which is connected to 'a pin '72 v which projectsfrom the 'bracketf 43 ;"above the point ofconnection of the spring with 'the' part 65. Thus thespring 71 holds the part 65 hormally in the position shown by fulllinesin the drawings with its tooth 68 in engagement :with the" pin 69.- When the rearward-end: of

- the arm -65' is depressedagainst the 1 actionof 'thespring'll, the tooth I 68 of the arm 65 is dis'engaged'from the lower end -of-the pin 69, thereby releasingthe arm 65 and permitting the spring'll to move it rearwardly tothe position shown by dot-and-dash lines in Fig. 5. The

forward and rearward movements of thearm 65 are limited by the endwalls' of a slot 73 therein engaging the pin 72 which extends'through the slot. The top wall of this slot 73 also limits the upward and downward movements ofthe rearward end of the arm 65. The arm 65 is provided with a cam surface 7 which is inclinedupwar'dly and forwardly from the top of the tooth 68. Whenthe arm 65 is released from the pin 69 andfis moved rearwardly by the spring 71 to the"dotand'-dash line position shown in Fig.5, the cam, surface '74; acting against the bottom of the pin 69; raises the pin and thereby raises the gear wheel 49 mm engagement with the gear wheel 50' and stops the rotation of the pinion '48; and, when the'arm 65 is moved forwardly by hand to the normal position thereof, the cam '74 permits the pin 69 and shaft 47 to be lowered by gravity thereon, and fulcrumed, at 87, on the arm 86 until 'thebevel gear wheel 49 is re-engagedwith the "bevel gear .wheelf59 causing the re-actuation. of thepinion 48 and nut gear 25 by the gear wheel 50, whereupon the spring 71f reengages the tooth 68 with" the pin'69 when the arm165 is released in its normal or set position.

*The" lower 'end' of the arm or link 66 extends to a, position adjacent to oneside of thesleeve 59 of "thewhirl disc 9 and it has a ,pin '75 secured to its lower end portion. The pin'75"eX-' tends from the link 66 inwardly through and beyond a verticalslot in .a fixed-arm '76 which is formedon'and extends downwardly from the bearing 5; When the part 65 is released and moved r'earwa rdly from its normal position shown in Fig. 2 to the position shown by. dot-and-dash line n' Fig. 5, and then'returned. to its normal po'sltiodj'the link66 and. its pin '75 will be raised and l-oweredby the a'ction' oi the arm 62: .Thejinnerl end portion of the pin '75 extends into the "groove 60 (Fig. 1) in the sleeve59 of lthe whirl disc 9 and.it is'jadaptedtoengag'e the flange 61 and'raise and 'lower'the disc 9 from and 'into engagement with the leathercov- 'ering on the wheel 11, thereby disconnecting the disc or spindle driving element 9from the wheel 7 or driven element 11 and stopping the acutation .of the disc 9 and spindle 4 bythe wheel/l1 when the disc is raised; and connecting the disc' and wheel '11 and resuming the actuation of the disc 9 and spindle 4 by the'wheel'll when the disc is lowered.

Itwill now be understood-thatwhen-the arm "or part 65 is set in its normal-position shown .in Fig. 2,, thejnut gear 25' and; the "winding spindle 4, will be actuated by the mechanism-0t the machine, and that when the arm 65 is retheir operation under the influence of themain directly overthi's'surface is the free end portion of'a horizontally extending portion .78 on the,

lowerarm of a lever '79 whichis fulcrumed, at 80, on-the bearing bracket 43, and which .has a straight arm 81' which extendsupwardly from the fulcrum 80. This lever '79 is movable on its fulcrum within the limits allowed by a 'pin 82 which projects from the bearing-bracket 43 and into an opening 83 in the lever arm 78.

When-the lever 79 is'moved'in the direction of the arrow in Fig. 7 the lever arm '78 will depress the rearwardendof the arm 65 and disengage the tooth 68 from the pin 69 and thereby releasethe arm 65 for its actuation by the spring 71 to stop the actuation-of the nut gear 25 and windingspindle-i as previously described; and when the arm 65 is restored to its normal position; as shown in Fig. 2, by hand, as previously explained, the rearward end .of the arm: 65 will movethe'lever '79 back'to its normal position shown in Figs. 1 and 7. I The lever arm 81 is located adjacent to the cam401 and it'is' provided with a collar 34 which is vertically adjustable thereon. The collar .84 is provided with a suitable set screw to hold it in positions of adjustment, and it is also provided with a downwardly extending projection 85' for a purpose presently appearing.

The cam 40 has a projecting arm 86 formed is a smalllever 88, one arm 89 of which is bent an'dtextends to a'position beneath the projection 85 onthe co1lar;84. The relationof the lever. arm 89130 the leverarm 81 is such that when. the cam 40 is' raised, on the bar'42 a sufficient distance theleverarm 89. will engage-the "projection' 85 and'willibe'thereby forced downwardly onits fulcrum 8'7 and thus. caused to 7 The arm 31 of the yarn guiding lever29 carried by the nut gear 25 is provided with a projection '90 which passes the small lever 88 each time the.

lever is raised and lowered by the builderframeil,

and which ismoved to and from a position directly beneath the lever88 as the bracket 38 on the lever 29 moves down and up in contact with the cam surface 37' againstwhich the bracketis held by the pull of the yarn 37pas'sing tothe cone 8.

When the yarn guiding lever 29 is in its lowermost position with relation'to the cam 40 the pro jection 9 0 is directly beneath the lever 88, and, so long as the yarn 37 is feeding to the cone 8 the bracketf38 will follow the cam surface 39 and the projection '90will be moved from beneath the lever 88 to clear the same as the lever 29' and bracket 38'ascend. When, however, the yarn 3'7 "breaks or dis'continues-its-ieed to the cone 8 for anyreason, the pull of the yarn will nolonger maintain the bracket 38 in engagement with the cam surface 39', after thecam surfac'e'SQhas moved the projection 90'to a positionbeneath the 'lever' 88 on the next descent-of-the lever 88-and is wound upon the spindle, and, during. the windthe projection 90 will remain in such position. Therefore, upon the next upward movement of the lever29 the projection 90 thereon will engage the lever 88and thereby rock the same on its fulcrum 87 and cause its arm 39 to engage the lever arm 81 and move it in the direction of the arrow in Fig. '7 for the release of the arm and the consequent stoppage of the actuation of the winding spindle 4 and the nut gear 25. I

If the inclination of the cam surface 39 is insuificient to cause the projection to move to a position beneath the lever 38 during the downward movement of the projection 90 while the pull of the yarn 37 holds the bracket 38 against the cam surface 39, the action of the pinion 48 against the nut gear 25 will cause the friction between the nut gear and the sleeve 24 of the lever arm 31 to move the projection90 to the desired position beneath the lever 88 for the, stoppage of the actuation of the winding spindle 4- and nut gear 25 upon the nextupward movement of the projection 90 whenthe yarn 37 breaks or is discontinued and thereby ceases to press the bracket 38 against the cam surface 39.

The drawings show the positions of the parts of the machine which they occupy just prior to the completion of the winding of the yarn package 91 on the spindle 4. The package 91 comprises the foundation or cone 8 and the body of yarn 92 wound thereon. Prior to the beginning, of the winding of the body .of yarn 92 upon the cone 8, the nut gear 25 is lowered by hand upon the screw 23 to a position where the yarn guide 33 will start the winding of the yarn at the level 93 on the cone 8; and at the sametime the cam 40 is lowered on the bar 42 by the lowering of the nut gear 25. When these parts are lowered the pinion 48 and winding spindle 4 are idle and the part 65 is out of its normal position shown in Fig. 2..

Assuming that the nut gear 25 and cam 40'have been lowered to the positions above set forth and that the main driving shaft 12 is being continuously rotated, the operation of the machine, briefly described, is as follows:

The yarn 37 is attached to the 'lowerportion of the cone 8,-in the usual manner, and the part 65 is moved forwardly by hand to the normalposition shown in Fig. 2, thereby starting the actuation of the pinion 48 and the winding spindle4.

As the spindle 4 and cone 8 thereon rotate, the yarn 37 passes'through the yarn guide 33 and ing operation, the builder frame 14 and therewith the screw 23, nut gear 25 and yarn guide 33 are raised and lowered by the earns 20 for building successive, open, helical layers of yarn upon the cone 8 and upon each other.

The extent of the up and down movements of the yarn guide 33 by the builder frame, 14 is equal to the distance between the lines 95 and 96 Fig. 2.

At the beginning of the winding of the body of yarn 92 upon the cone 8, the yarn guide 33 is moved up and down to feed yarn to the cone 8 between the levels 93 and 94, and while the up anddown traverse of the guide 33 under the influence of the builder frame 14 is substantially These gain movements areimparted to the yarn guide 33 by the pawl 53turning the ratchet whee152 and causing it to turn the bevel gear wheels 49 and 50 and pinion 48which turns the nutgear 25 and causes it and the yarn guide 33 to move upwardly on the screw 23 a slight distance at each upward movement of the builder frame 14 during the reciprocation thereof. j I During the traverse or up and down movements of the yarn guide 33 the pull of theyarn 3'7 upon the guide 33 holds the bracket 38 against the cam40 and the cam 40 moves the guide 33 gradually away; from the cone 8 during the downward movement of the guide and permits the pull of the yarn to movethe guide gradually toward the cone during the upward movement of the guide so that, during the up and down traverse of the guide, it will follow a line substantially parallel to or approximating the adjacent surface of the body of yarn being wound upon the cone. This movement of the yarn guide 33 keeps it at all times in close proximity tothe body of yarn 92 upon the cone and causes the helical layers of yarn to be laid on the cone 3 in a manner to extend up and down thereon a distance more nearly ap- 100 proximating the full traverse of the yarn guide '33 than in machine constructions wherein the yarn guide is moved up and down in a vertical line; because, in the latter case, the yarn guide is distinctly farther from the cone at the top of its stroke than at the bottom thereof. 1

Each .time a gain movement is imparted to the yarn guide 33 the bracket 38 on the lever 29 carrying the guide 33 engages the projection 45 on the cam 40 and moves the cam upwardly on the bar 42 a distance equal to the extent of the gain movement of the guide.

Upon the completion of the winding of the body of yarn 92 upon the cone 8, the upward move.- ment of the cam 40 causes the arm 89 of the lever 88 carried by the cam 40 to engage the projection 85 of the collar 84 on the lever arm 81 and operate the lever 79 to release the part 65 and there,- by stop the operation of the winding spindle 4 and pinion 48, and thus stop the winding of the yarn upon the cone48 and also stop the gain movements of the yarn guide 33 'while the main shaft 12 continues to rotate and the builder frame 14 continues to move up and down. p The size of the yarn package 91 or the body of yarn 92 wound upon the cone 8 may be governed and controlled-by adjusting the collar 84' up and down upon the lever am 81. When the collar 84 is movedto a lower position on the lever arm 81, the winding operation will be 7 automatically stopped when the yarn guide reaches a lower-level; and, when the collar 84 is moved to a'high'er posi} iion on the lever arm 81 the winding operation will beautomatically stopped when the yarn guide reaches a higher level. V f After the completion of the winding of the body of yarn 92 upon the cone 8 and the tripping of the part 65 to stop the rotation of the spindle 4and the operation of the pinion 48, the yarn 37 is severed andthe yarn package 91 or the cone 8 140 containing the body of yarn 92 is removed from the spindle 4 and a fresh, empty cone is placed upon the spindle for a succeeding yarn winding operation This being done, the arm 26 on the nut gear 25 is moved out of engagement with the guide 33 is in a position to deliver yarn to the fresh cone placed upon the spindle, at the level 593 when the builder frame 14 is in the down position, the arm 26 of the-nut gear -isre-engaged' withthe screw 23, the yarn37 being delivered by the guide 33 is attached to the fresh cone, the arm or part 65 is moved forwardly to -its set position to start the operation-of the winding spindle 4 and pinion 48 and the winding operation is repeated. 1

g If, at any time during the winding of the body of yarn 92 upon the'cone 8, the strand of yarn 37 should break or be discontinued-for any cause, the cam 40 willmove the projection 90 on the lever 29 to a positionbeneath the lever88 dur ng the next downward movement of the builder frame 14 and the projection 90 will remain in aposition beneath the lever 88 during the-succeedingupward movement of the builder frame because there will be no yarn pull to hold the bracket .38

against the cam 40; consequently, during such next succeeding upward movement of the builder frame 14 the projection 90 will engage the-lever 88and cause it to-operate the lever 79 to trip the armor part and thus stop the "rotation of the winding spindle 4 and also stop the operation of the pinion 48 for effecting the gain movements or the yarn guide.

If it should be desired for any'reason whatsoe ever to stop the rotation'of the winding spindle 4 and the operation of the pinion 48'at any time during the" winding operation,the same may be easily and quickly done, by merely raising the forward end of the part or arm 65 and thereby tripping it by releasing-its tooth 68 from the pin 69, or'the part or arm 65 maybe easily-and quickly tripped by'moving the level arm 31in the direction of the arrow in Fig. 7 by hand. l

The frame bar 15 may be provided with any desired number of the brackets 8 and 43supporting additional winding spindles and shafts like the winding spindle 4 and shaft 47, and such additional winding spindles andshafts may be actuatedby the main driving shaft 12 andthe shaft 51, respectively, like the spindle4 and the shaft 4'7 are actuated thereby for the same purpose.
