IO senting like parts.
This invention relates more particularly to apparatus adapted to effect the winding of yarn upon a yarn-receiver or bobbin in such manner that a preliminary winding or bunch I is first laid and thereafter a main or service winding is laid. Yarn-receivers so wound are subsequently used in the shuttles of automatic filling-replenishing 'feeler-looms, a feeler acting to cause a change of filling when the yarn has been woven off down to the preliminary winding, the latter still containing sufficient yarn to last while the change is being made.
I have previously obtained two United States Patents for apparatus of the character above specified, No. 686,906, dated November 19, 1901, and No. 72:2,15, dated March 3, 1903, the ring-rail being given a short traverse during the formation of the bunch, and the traverse is then lengthened automatically to lay the main or service winding. Both forms of patented apparatus employ a reciprocating carriage included in the operatingconnections between the ring-rail and the builder-motion, 5 and such carriage and the portion of the apparatus adjacent thereto carry the means to control automatically the builder-motion and effect the change of traverse.
In my present invention 1 have dispensed with the carriage altogether, and the traverse shifting and controlling means is constructed practically as a part of the builder-motion, thereby obviating the employment of separate mechanism necessary in the patented apparatus.
The change or shifting of the traverse is effected automatically in the present embodiment of my invention, and l have provided novel means whereby the volume of the preliminary winding can be regulated very accurately and readily. I have also so constructed the apparatus that after dofling and windin readiness to begin the preliminary or bunch winding on a new set of yarn-receivers when the frame is started.
The apparatus can be utilized for plain -winding---that, is, without the formation of the bunch by throwing into a different position a single member of the apparatus, the return of such member to its usual position setting the apparatus for bunch-wimling.
The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

In the earlier of the two patents referred to the ring-rail is raised by means of a lifting-weight and depressed by or through the builder motion, the drum of the winding mechanism thereof being gradually unwound to effect the gain of the traverse by letting off the chain little by little as the yarn is laid upon the yarn-receiver. My present invention is shown as applied to a frame of similar construction and operation, though its use is not restricted thereto, as will be manifest to those skilled in the art. It will be understood that the gradual unwinding of the chain secured at one end of the drum and connected indirectly with the ring-rail effects the gain of the traverse, whereby at each upstroke the ring-rail rises a little higher and at each downstroke descends not quite so low as on the previous downstroke to lay the yarn in successive layers upon the bobbin from the lower end or base thereof to the upper end.
In Figs. 1 and 2 the spindle-rail 1, on which are mounted rotatable spindles 2 of the sleevewhirl type, as herein shown, the verticallyreciprocating ring-rail 3, provided with rings 4, one for each spindle, the usual lifter-rods 5, only one being shown in Fig. 1, the rocker 6, cooperating with the foot of the lifter-rod and provided with a weight 7 to elevate the ring-rail, and the upturned rocker-arm 8, rigidly connected With the rocker and transmitting reciprocating movement to the other lifter-rods through the link 9, may be and are all substantially of well-known or usual construction in spinning or similar apparatus. The end of the rocker 6 is extended beyond the foot of the lifter-rod to form a pedal or foot-piece 10, Fig. 1, and an upturned arm 11, shouldered at 12, Fig. 1, is fulcrumed at 13 on the rocker and provided with a lateral foot-piece 14, the arm constituting a downhold for the ring-rail when the shoulder 12 is brought under the longitudinal girth 15 of the main frame. Under normal conditions the downhold rises and falls with the oscillatory movement of the rocker 6, the shoulder never descending low enough to catch under the lower edge of the girth 15; but when the operator Wishes to depress the ring-rail, as for dofling, he places his foot on the foot-piece 14 and presses down the rocker until the shoulder 12 passes under the girth. Thereupon the weight7 will hold the shoulder and girthin engagement with the ring-rail in dofiing position, and to release the ring-rail the footpiece 10 is depressed, permitting the weight of the downhold to swing it back away from the girth into the position shown in Figs. 1 and 1, thereby freeing the ring-rail from control by the said downhold. The operation of'this portion of the mechanism will be referred to hereinafter in connection with the change from long to short traverse and the windingback operation. The rocker 6 has a rigidlyconnected arm 16, provided with a segmental upper end 17, to which is secured one end of a chain or other flexible connection 18, which passes over a fixedly-sustained guide-sheave 19, Fig. 1, and thence down to the winding mechanism to be referred to, the builder-motion acting through the chain to positively depress the ring-rail and permitting its ascent by the weight 7.
I have herein shown the builder-motion as including two connected rocking members movable in unison and also having a differential motion, one of said members being hereinafter termed the builder-arm and the other member the traverse-shifter. The builder-arm 20, shown as an elongated bar, has at its inner end a long hub 21, Fig. 3, fulcrumed on a shaft 22, rigidly supported by the end frame 23 and an upright standard 24, Fig. 1, collars 25 on the shaft preventing endwise movement of the hub, the latter having a radial brace 26 extended therefrom parallel with the arm 20 and connected therewith by a short fixed shaft 27. on the builder-arm, provided with an upturned guide-lug 28, Figs. 3 and 4, for a purpose to be described, the builder-arm being provided with a roller or other stud 29, constituting a follower to cooperate with a single actuator, shown as a traverse-cam 30, herein illustrated as a four-point cam, Fig. 5. The follower 29 is made adjustable on the builder arm by means of the plate 31, bolted thereto, Fig. 4, and a guide-lug 32 is upturned from said plate above the top of the arm.
- The short shaft 27 is near the center of the builder-arm and has loosely mounted upon it the hub 33 of the traverse-shifter, shown as an arm 34 extended in parallelism with and adjacent the builder-arm to its outer free end, said traverse-shifter having mounted upon it the winding mechanism of substantially usual construction. Said mechanism includes a drum 35, pick-shaft 36, provided with a worm 37 to effect gradual rotation of the drum, pick-wheel 38 on said shaft 36, Figs. 2 and 4, an actuating-pawl 39, operated in usual manner when long traverse is in action, and a second actuating-pawl 40, operated during short traverse. Rotation of the cam oscillates or rocks the builder-arm 20 on its fulcruin 22 with a constant stroke, and a Weight 41, (see Fig. 2,) attached to one end of a chain 42, which passes over guide-sheaves 43 44 and which is secured to the free end of the builder-arm, counterbalances the weight of the parts carried by the builder-arm and maintainsthe follower 29 in engagement with the actuating-cam 30.
The gradual unwinding of the chain 18 by rotation of the drum effects the gain of the traverse, as will be manifest, and when the long traverse is used the builder-arm 20 and Said shaft enters a boss traverse-shifter 3% rock in unison on the full spring 60 is uncompressed; but if said spring crum '22, and at such time the rotation of the drum is controlled by the pawl 39, Fig. l; but when short traverse is used the traverseshifter 3 rocks about a different and temporary fulcrum, to be described, its movement being so slight that the pawl 39 cannot then control the drum. Then the pawl 40, mounted on the depending arm *5 of a bracket 46, secured to the free end of the builder-arm, is called into action to control the gain, the relative movement of the adjacent portions of builder-arm and traverse-shifter being sutiicient for the purpose. The bracket has an upturned arm 4:7, bent laterally across and above the builder-arufaml provided with an upward extension a8 (see Fig. l) for a purpose to be described.
It will be obvious that when the members 20 and 3% are coupled or locked to rock in unison on the fulcrum 22 the traverse of the ring-rail will correspond to and be directly controlled by the constant stroke imparted by the actuating-cam to the builder-arm, and this longer uniform traverse is employed to lay a main or service winding u" on a yarnreceiver or bobbin 1/1. (See Fig. 10.) \Vhen, however, a preliminary winding or bunch w is laid upon the yarnreceiver, it is laid with a shorter uniform traverse, and in order to effect such short traverse the traverse-shifter 3% is rocked about a fulcrum different from that of the builder-arm and with a much shorter stroke than the latter. To this end a fulcrum member 49 50 is pivoted at 51 to the outer end of the traverse-shifter, the parts being adjustably connected by a bolt 52 to vary the position of the pivot 51, the latter being the fulcrum about which the traverseshifter rocks during the short traverse or bunchbuilding period. A shoulder 53 on the fulcrum member is adapted when said member is operative to engage the under side of the girth 15, as shown in l, .2, and 4, whereby the fulcrum member is held stationary by the action of the lifting-weight 7 exerted through the chain 18 upon the winding mechanism.
On the front end of the traverseshifter is fulcrumed at 5&(see Figs. 6, T, and 8) a transverse latch 55, having a rib 56 on its upper face at the side of its fulcrum nearer the builder-arm and a slot 57 in its opposite end, the slot receiving loosely the lower end of a pin 58, secured at its upper end in an ear 59 on the fulcrum member, a spring 60 being coiled around the pin between the ear and the latch. Beneath the latch the traverse-shifter is enlarged laterally to form stop-faces 61 62, Fig. 8, which permit a rocking movement of the latch and also act tolimit such movement.
The center of gravity of the fulcrum member is so disposed with relation to the pivot 51 that said member tends to swing forward into position to cooperate with the girth 15 if the is compressed by movement of the latch into the position shown in Fig. 8 the expansion of the spring will swing the fulcrum member into inoperative position, Fig. 5, just as soon as the downstroke of the builder-arm carries down the outer end of the traverse-shifter, as
will be explained, and the shoulder 53 is separated from the girth l5. \Vhen the fulcrum member is inoperative, a lug 63 thereon rests on a stop Gl, rising from the traverse-shifter, (see Figs. 5, 7, and 8,) and so long as the latch is held against the stop-face til the spring (it) will be under sul'licient compression to maintain the fulcrum member inoperatively positioned.
Referring momentarily to Fig. 2., it will be seen that when the fulcrum member is operatively positioned the outer end of the traverse-shifter 3i will be held practically stationary and its inner end will swing through an arc equal to the are through which the short shaft 27 is moved by the constant stroke of the builder-arm. Inasmuch as this arc is much smaller than the are of movement at the outer end of the builder-arm, it will be obvious that the amplitude of movement of the traverseshi'fter will be very much less than that of the builder-arnn'and consequently the traverse of the ring-rail will be correspondingly short to lay the preliminary or bunch winding of yarn. Such windingcontinues solongas the fulcrum member is in engagement with the girth l5, and I will now describe the means for automatically changing the latch from the position shown in Fig. l to that shown in Figs. 5 to 8, inclusive, to thereby change from short to long traverse and shift from the bunch to the main or service windii'ig of the yarn.
Upon the top of the builder-arm is mounted a sliding controlling device or latch-dog, shown separately in Fig. 9 as comprising two elongated members 65 66, longitmlinallyslotted at 65 66 respectively, and placed end to end. the part (56 having a housing (37 for a headed plunger 68, secured to the upturned end of the part (55, a strong spring ()9 between the plunger-head and the inner end of the housing normally acting to pull the parts together, so that the two-part latch-dog will move as one piece. A transverse notch T0 in the under side of the part 66, near its front end, is adapted to at times receive the latchrib 56, hereinbefore referred to, and the part 65 is provided with two cars Tl 72 and with an upright shoulder 73 at or near its rear end. The lateh-dog is longitudinally slidable along the top of the builder-arm and is held thereon and guided by headed studs which pass loosely through the slots 65* and 66 into the builder-arm, the guide-lugs 2S and 32 also assisting in guiding the latch-dog. A short arm 74: on the hub 21 has fulcrumed upon it a detent 75, shaped to engage the shoulder 73 and retain the latch-dog 1n the &
position shown in Figs. 2 and 4 against the action of an actuator, shown as a weighted lever76, fulcrumed on the side of the builderarm and having a short upturned finger 77, adapted to engage a pin 78, extended laterally from the member of the latch-dog. WVhen the detent is disengaged from the shoulder 73, the weight of the actuator swings the finger 77 forward, and through the pin 78 the latch-dog is moved forward until its front end projects above the ribbed portion of the latch 55 on the traverse-shifter, as in Fig. 5. hen the latch-dog is thus moved forward, the next downward stroke of the builder-arm brings the rib 56 into the notch and turns the latch into the position shown in Fig. 8 against the stop-face 61 and compresses the spring 60. Consequently the latter by expanding-when the builder-arm carries down the outer end of the traverse-shifter returns the fulcrum member 49 50 to inoperative position, and the cooperation of the latch and latch-dog couples or locks the builder-arm and traverse-shifter together to oscillate in unison, and short traverse is thus terminated and long traverse begun.
I have devised simple means to automatically release the latch-dog from control of the detent, and for such purpose the detent is provided with a forward extension 79in the path of movement of a tripping-pin 80, projecting laterally from a controlling-ratchet 81, rotatably mounted on a stand 82, secured to the builder-arm near its fulcrum. The axle 83 of the ratchet has adjustably secured to it by a set-screw 84, Fig. 3, a weighted arm 85, which tends to always return the ratchet to a definite position-viz., that shown in Figs. 2, 4, and 5a pawl 86, fulcrumed on the ear 7 3 of the latch-dog, acting at times to prevent rotation of the ratchet in the direction due to the action of said weighted arm. As the detent-pawl 86 is mounted on the latch-dog, movement of the latter into operative position by the actuator 76 will disengage the pawl from the controlling-ratchet, as in Fig. 5. Step-by-step forward angular movement of the ratchet is effected by a pawl 87, pivoted on the rear end of an arm 88, fulcrumed on a stud 89, extended from the end frame 23, the front end of the arm having depending from it a preferably adjustable foot 90. The foot is located in the path of the extension 48 of the bracket 46, secured to the front end of the builder-arm, and when the latter rises the extension hits the foot and rocks the arm 88, depressing the pawl 87, and thereby advancing the ratchet 81 an angular distance constituting a step. Starting from the position shown in Fig. 4, then a predetermined number of angular advances or steps of the ratchet will cause the tripping-pin to engage the extension 79, and thereby lift the detent 75 from engagement with the shoulder 78, whereupon the latchdog 65 66 will be moved. forward into operative position by the actuator 76. As each advance of the ratchet is equivalent to a stroke of the builder-arm and this is accompanied by an equal number of strokes of the traverse-shifter, it will be seen that the release of the latch-dog is effected when a predetermined number of short=traverse strokes of the ring-rail have been made. By setting the pin 80 nearer to the detent extension 79 the release will be effected when a less number of traverses have been made, and consequently when less yarn will have been laid in forming the bunch, so that by regulating the amount of angular movement of the ratchet the volume of yarn in the bunch is regu-. lated. As the latch-dog is moved forward the detent-pawl 86 is disengaged from the ratchet 81, and the weighted arm operates to return it to initial position, the descent of the outer end of the builder-arm permitting the quick return of the ratchet to temporarily throw out the operating-pawl 87. It will be remembered that as soon as the latch-dog and latch 55 cooperate the builder-arm and traverse-shifter are coupled or locked together, and thereafter the traverse will be long, and the main or service winding 20, Fig. 10, will be laid, completing the winding.
The barrel of the bobbin m, Fig. 10, has near its head or base m a portionm which is substantially cylindrical and technically termed the feeler-wood, and upon this part the preliminary winding or bunch w is wound with the short uniform traverse, as has been described.
The completion of the winding by the service-winding is indicated at w by dotted lines, Fig. 10, both windings being wound with the filling-wind, the gain of the traverse acting during each winding, as has been set forth.
Referring now to Figs. 6 and 7, the side of the drum 35 of the winding mechanism adjacent the traverse-shifter 34 has formed thereon a cam 91, shown as an incomplete circular rib, and a resetting-pawl 92 is fulcrumed on the ear 71 of the sliding latch-dog 6566, said pawl having a depending tooth 93, which is arranged to cooperate with the cam 91. During the gradual unwinding of the chain 18 from the drum the tooth 93 will ride upon the cam 91, the rotation of the drum being indicatedby the arrow, Fig.- 7, and when the lIO main'or service winding has been completed the tooth will drop into the space between the two ends of the circular cam. When the winding-back operation is performed by the operator, the end 94 of the cam will engage the tooth, and as rotation of the drum is then opposite to the arrow, Fig. 7, the resettingpawl 92 will be forced to the left, viewing said figure, and it will retract the part 65 of the latch-dog to the position shown in Fig. 4, the detent-pawl 75 automatically engaging the shoulder 73, and those parts will be reset. Let it be supposed that the winding of a set of bobbins has been completed and that the ring-rail is at its highest position, while the tooth 93 is between the ends of the circular cam 91. The operator then depresses the ring-rail by pressing down upon the foot-piece 14 until theshoulder 12 of the arm 11 catches under the girth 15, holding the rail down. Such downward movement of the ring-rail relieves the traverse-shifter 3% of the weight of the counterbalance T, slackening the chain 18, and the traverse-shifter is then free to swing downward on its pivotal connection 27 with the builder-arm, such downward swing 1 withdrawing the ribbed end of the latch 55 from the notch 70 of the latch-dog, and the builder-arm and traverse-shifter are thereby unlocked or uncoupled. Now the operator winds back, (either before or after ;loffing,) taking up the slack of the chain 18 on the drum 35 as it is rotated oppositely to the arrow, Fig. 7, and at the same time causing the end 9-1 of the cam 91 to act upon the tooth 93 of the pawl 92, moving the latch-dog back or resetting it in the position shown in Fig. 1. The spring 69 is strong enough to cause the part 66 of the dog to move back with the part 65, and as the latch-dog is caught the curved portion of the cam acts upon the projecting toe 95 of the pawl 92 and throws the tooth out of engagement with the end 9% of the cam. \Vhen the latch-dog is thus withdrawn and reset, its notched forward end is moved back out of the path of the latch before starting up the frame the operator releases the downhold 11, so that the ring-rail is returned to the control of the weight 7 prior to starting the formation of the bunchwinding on the fresh set of bobbins. The action of the weight 7 acts through the chain 18 to lift the free outer end of the traverseshifter 31 until the shoulder 53 of the fulcrum member or dog a9 50 engages the girth 15. stopping further upward movement.
The
release of the latch from the latch-dog perback, and as the ring-rail is not low enough to permit dofling it must be still further depressed, and this is effected by means of the foot-piece 1i, as before, the downhold 11 retaining the rail lowered for dolling; but this acts as previously to relieve the traverseshif'ter of the upward pull due to the counterbalance 7, and the traverse-shifter drops far enough todisengage the latch from the notched part 66 of the latch-dog. Instantly the compressed spring expands and retracts the part 66 from the path of the latch and causes it to abut against the end of the previouslyreset part 65, the fulcrum member on the traverse-shifter swinging into position ready to cooperate with the girth 15, as before, on the next succeeding upward movement of the outer end of the traverse-shifter.
From the foregoing description of the two methods of handling the apparatus when the winding of a set of bobbins has been completed it will be understoodreadily that if the first method of operation were always practiced there would be no necessity for the twopart construction of the sliding latch-dog and the spring connection between them. In practicing the second method such structure is necessary, becauscthe resetting-pawl is caused to operate while the front end of the latchdog and the latch are locked together during winding back. Should it be desired to utilize the apparatus for regular winding of the yarn upon the yaru-receivers or bobbins, the resetting-pawl is either thrown back out of cooperation with its controlling-cam or it can be detached from the latch-dog, the latter then maintaining continuous engagement with the latch on the traverse-shifter. Such engage- 'ment serves to maintain the spring 60 under sufiicient compression to retain the fulcrum membera950in inoperativeposition. (Shown in Fig. 5.)
\Vl en winding back, the operator applies a suitable key to the pickshaft 56, the front end of the latter having a socket 96, Fig. 1, to re- 1 celve the end 97 of the key, Figs. 11 and 12 if the foregoing operation were always folf lowed, the two-part construction of the latchtion is varied by the operator winding back upon completion of the set of bobbins against the resistance of the counterbalance T, such resistance tending to keep the r1b 56 of the dle 100. dog would be unnecessary; but such opera- 3 in the present construction, and the key is shown as having a circular head 98, provided with an annular beveled flange 99 and a han- \Vhen the key is applied, the beveled edge of the flange passes under and disengages the two pick-pawls 32) and if) from the pick-wheel 38, so that the said pawls will slide over the flange as the winding back is effected. latch in operative engagement with the notch being reset; but as the part 66 is held from movement the spring 69 is compressed as the plunger 68 is drawn into the housing 67. The operator doffs after completing the winding The mechanism for automatically shifting from short to long traverse and for controlling the time during which short traverse is effective are all practically included as a part of the builder-motion and are carried by the builder-arm, the construction eliminating the employment of a reciprocating carriage and parts carried thereby, as in earlier structures invented by me and referred to hereinbefore.
By slightly taking up or letting off the chain 18 in the usual manner the position of the ring-rail can be varied to change the position of the bunch-winding, and the same result can also be attained by adjustment of the two parts of the fulcrum member or dog one relatively to the other.
A variation can be made in the length of traverse, both short and long. by adjustment of the follower on the builder-arm, an increased stroke being effected by adjustment to ward the builder-arm fulcrum and a decreased stroke by adjustment of the follower in the opposite direction.
My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be varied or modified in different particulars by those skilled in the art without departing from the spirit and scope of my invention.
