MACHINE FOR DOUBLING AND WINDING YARN OR THREAD UPON BDBBIN,S.

-n 3IFIGATEON forming part of Letters Patent No. 313,869, dated March 17, 1885.

Application filed October 19, 18 2.

such as will enableothers skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates to thatclass of ma chines employed for doubling and winding thread commonly known as drum-winding machines. I

In an application for patent filed by us of even date herewith we have shown and claimed certain improvements in devices whereby upon the breakage or absence of a thread the bobbin is lifted clear of the driving-drum.

The presentinvention is designed as an improvement thereon; and it consists in the combination, with a detector-plate and a bobbin frame or carrier, of mechanism whereby said carrier is held with its bobbin out of con tact with the driving-drum, whereby the momentum of the bobbin is arrested, the move ment of the carrier in a direction away from the drum limited, and whereby said carrier may be moved into a position relatively to its support with the bobbin out of contactwith the latter, substantially as hereinafter fully de scribed.

In the accompanying drawings, Figure l is a sectional elevation of a double machine illustrating one construction of bobbin-lifting devices and a modification thereof. Fig. 2 is a like view, on an enlarged scale, of the bob- Fig. 3 is a plan view of Fig. 2. Fig at is a sectional elevation of a modification in the construction of the bobbin frame or carrier shown on the right of Figs. 1 and 2 and 011 the left of Fig. 8. Fig. 5 is a like view showing the bobbin frame or carrier of Fig. 4 lifted 'clear of the driving-drum and lever-frame. Fig. 5 is (No model.) Patented in England July I), I831, No. 3,132.

aperspective view of thebrake-levcrD shown in Figs. 4 and Fig. (3 is a sectional elevation of a further modification in the construction of the bobbin-lifting devices. Fig. 7 is a plan view thereof. Fig. 8 shows another modiiication of the said bobbin-lifting appliances. Figs. 9, 10, 11, and 12 are detail views of an improved detector-plate, and 13 is a de tached view showing the mode of pivoting the detector-plate.

Like letters of reference indicate like parts wherever such may occur in the above figures of drawings.

A, Fig. 1, indicates the main frame, of any suitable material, and constructed to support the operative mechanism, and in order that this latter may be better understood we will first describe that construction shown on the right of Figs. 1 and 2 and on the left of Fig. 3.

C indicates the drivingdrum,and H the bobbin, the spindleh of which rotates in bearing-grooves b formed in the side bars b of a frame or carrier, B, one of which side bars is extended to form a handle, B The side bars b are connected together at their rear ends by a cross-bar, B", provided on its under side with bearings in which is secured a pivot-pin, 1), upon which is pivoted the rear end or long arm of an angular lever, D, that has its fulcrum at d in a bracket, a, attached to the beam A, that extends from end to end of the machine. The lever D is composed of two angular side bars, forming short and long arms on theinner and outer side of the fulcrum cl, respectively. The sidebars (Z on the inner side of the fulcrum, which constitute theshort arm of the lever D, are connected by a crossbar, at, a like crossbar connecting said arms on the outer side of the fulcrum d,'as plainly shown in Figs. 2 and 3.

Upon the pin b, between the arms d of lever D, is pivoted a tripping-lever, F, composed of the socketed shankf and the pinf, adjustable within the socket of the shank by means of a set-screw,f-. The free end of the tripping-lever projects outwardly, and is adapted to bear against a stop, e, that projects from the detector-plate E, and lies upon the upper face of the beam A, in which said plate E is pivoted. The side bars I; of the bobbin frame or carrier may be weighted in any suitmentum of said bobbin.

able manner. WVe preferably provide these bars with meanssuch as the holes if, or equivalent means-for attaching a weight,b ,thereto, by means of a cord, as shown, or by means of a link or chain. When during the winding one or more threads break or is or are absent, the corresponding detector wire or wires drop down into the path of a cam-shaft or a prismshaped shaft, G, (preferablythe latter.) This shaft, impinging upon the lower end of the detector wire or wires, tilts the detector-plate E, its stop 6 being moved out of the way of the tripping-leverF to release the carrier and lever. Both the carrier B and lever D are now free to swing on the fulcrum d, the inner ends of the lever Dascendingto meetthe bobbin-carrier and support the bobbin, and at the same time 'act as a brake to arrest the mo- This movement of the lever D and bobbin-frame is greatly accelerated by the action of the weight b, so that the bobbin is rapidly carried out of contact with the driving-drum to enable the operator to find and tie the broken or absent thread or threads, as hereinafter explained, and at the same time said weight not only holds the bobbin firmly on the drum while in contact therewith, but also holds said bobbin firmly on the lever, and assists in checking or arresting itsmomentum.

By an inspection of the drawingsit will be seen that the bobbin-carrier is pivoted to the long arm of the lever D, and that, the latter has its fulcrum at d. Hence, if the trippinglever is released, the bobbin-carrier B will move outwardly or away from the drum, and downwardly, while the outer end of the lever D moves downwardly and its inner end upwardly against the bobbin, forthe purposes set forth,

the bobbin resting upon the lever end of.

Upon the pin 1), between the arms d of the lever D, is hung a flat leg or stop, B, the pin passing through avertical slot, If, in said stop.

. When the carrier and lever are tilted, as.

above described, to carry the bobbin away from the driving-drum and support it in that ,position, the lower face of the stop B comes in contact with the bracket a, andvits upper ,face with the under side of the cross-bar B thus limiting the downward movement of the carrier and lever, and supporting the same in r, the end d of the lever D.

the proper position.

Toenable the attendant to hold the bobbin .out of contact with the lever and rotate the same to find the broken or absent thread or threads,when said lever and carrier have been tilted as described he depresses the handle B slides over the outer upper corner of the stop B, downwardly a short distance, and carries with it the short arm of lever D and pin b,

, which latter moves down in the slot of the carrier bearing against the edge of the stop,

stop B a short distance, the crossbar of the e which thus affords a certain but small amount of leverage to support the carrier. This leverage and the frictional contact of the crossbar with the stop hold the carrier up with the bobbin out of contact with the lever, but not so securely that by applying a certain amount of force to the handle the carrier cannot be returned to its normal position. In this movement of the carrier with the lever the bobbin is carried away from the latter, owing to the difference in the distances traveled by the short arm of the lever and the longerside bars of the bobbin-carrier. This downward movement of the pivot-pin b and lever D in the slot of the stop will be readily understood when it is borne in mind that the stop B, when in contact with the bracket a, constitutes the support as well as the fulcrum from which the bobbin'carrierBis supported and upon which it can be tilted, and inasmuch as the pivotpin 1) for the long arm of the lever D passes through a slot in the stop, and the outer end of both the bobbin-carrier and lever can move downward when the carrier is tilted in the stop B, the pin will necessarily partake of this downward movement in the slot of the said stop, which movement is, however, a limited one, but sufficient to afford a bearing to hold the 'bobbin earrier withthe bobbin away from the lever D, as above stated. When the absent or broken thread or threads have been found and tied, and it is desired to return the bobbin in contact with the driving-drum, the

attendant lifts the carrier B by means of the handle B the pin 1) rising, in slot 1/ of the stop B until the cross-bar B of carrier B again lies onthe upper face of said stop B and the bobbin on the end at of lever D. By a slight further movement of carrier B in the direction of the drum 0 the stop B is lifted clear of the bracket (1, and the-carrier and lover will swing toward the drum sufficiently-to cause them to continue tomove in that direction by their own weight or by the latter assisted by the weight I).

Instead of supporting the bobbin-carrier B and lever D upon the stop B, they may be supported as shown in Figs. 4 and 5, wherein one of the side bars I) of the bobbin-carrier B has an outwardly and downwardly projecting extension or arm, B and upon the outer face of the transverse bar B of the carrier at its outer end are formed bearing-lugS,FigS. 2, 3, 6, 7, and 8, inwhich is secured the pivotpin 1). Upon this pin is pivoted the trippinglev'er F, the arm f of which extends rearwardly and bears against the tripping-arm e of the detector-plate E. As shown, this arm is made tapering, for purposes presently explained.

The lever D is pivoted upon a bracket, a, and is constructed as follows: Theinner short arm, d of the lever has a bearing-surface, (1 upon which the bobbin is supported when moved out of contact with the driving-drum. d are depending lugs constituting pivotal bearings, by means of which it is pivoted to bracket or. The outer or longer arm of the lever D is formed by two diverging arms, (1

(Z having lugs d projecting vertically there from and forming bearings, by means of which the said longer arm is pivoted to the outer end of the bobbin-carrier by means of the pivot-pin 2). One of the lugs d has, arms D" d", as plainly shown in Fig. 5", projecting vertically therefrom, the former serving as a handle and the latter as a rest or foot for supporting the lever and bobbincarrier when the lat ter has been tripped.

The operation of these devices is plainly illustrated in Figs. at and 5, and may be briefly described as follows: W'hen the parts are in their normal position, as shown in Fig. at in full lines, the bobbin is in contact with the driving-drum, held there by its own weight or by said weight b and an additional weight suspended from the carrier at 11",- but said bobbin is not in contact with the bearing-surface of the lever. \Vhen a thread or threads break or are absent, and the detector wire or wires thereof fall into the path of the rotating an gular bar G, the detectorplate E is tilted upward and its arm 6 moved away from the arm f of the tripping-lever F, thus allowing the bobbiucarrier B, and with it the lever D, to swing on the pivot of bracket 1, the inner arm, (1 of the lever rising to meet the downwardly-moving bobbin and support the same.

It is obvious that since the carrier B is pivoted at its outer end only to or with the lever D the inner end thereof, through the bobbin, is supported clear of the inner end of the lever D by the driving-drum, and that, as soon as said carrier moves outward and away from the drum, the bobbin moves downward until, when clear ofthe drum, it meets and is supported by the upwardlyinoving leverend or bearingsurface d The lever D, being pivoted about its longitudinal center, can there fore only swing downward on its pivot, and as its outer end swings downward its inner end necessarily swings upward to meet the downwardly-moving bobbin. In this manner the bobbin is not only supported by the end of lever D, but the extended bearing-surface d thereofacts as a brake to arrest the momentum of the bobbin. The downward motion of the outer end of the carrier and lever is limited by the extension or foot (1 coming to rest upon the beam A which extends or may extend from end to end of the machine, the bobbin being thus held out of contact with the driving-drum, as shown in dotted lines in Fig. 4. In this downward movement of the outer end of carrier B the armf' of the tripping-lever passes under the arm 6 of the during which movement of the arm the carrier and lever are slightly lifted or tilted on their respective pivots, and when said arm has passed over the beam the carrier and lever again drop down, the arm bearing against the vertical face of the beam and holds the carrier in the position shown in Fig. 5. To return the parts into their normal position, the attendant lifts the lever D, and with it the carrier, by means of the handle D until the arm B is clear of the beam A, when both lever and carrier will swing forward on their pivots, and said parts will then be in the position shown in dotted lines, Fig. 4. By lifting the carrier on pivot b, and then tilting the inner end of the same and that of the lever D downward until the arm f of lever F bears against the arm 0 of detectonplate E, and allowing the carrier to drop, the bobbin will again lie on the driving-drum, as shown in full lines, Fig. 4:.

Ve will now (.lQStllbG that construction of mechanism shown on the left of Figs. 1 and 2 and on the right of Fig. 3. In this construction the bobbin-carrier B is pivoted upon a fulcrum or axis, Z), that has its hearings in two arms, a", pivoted at a in bearings a secured to the beam A, that extends from end to end of the main frame. Upon the pivot-pin b is pivoted the trippinglever F, constructed substantially like the lever described hereinbefore, the outer or free end of which abuts against a; trippingarm, (2, secured to and projecting from the detector-plate E, the outer end of said arm lying upon the beam A", as shown.

Upon the beam A is secured an inclined flat plate, I, that extends under the bobbin H in proximity to the driving-drum G, and is of such a width as to adapt it to perform the functions of a brake to arrest the momentum of the bobbin when the carrier B descends 'to carry the bobbin onto said plate.

As shown in Fig. 1, the bobbin is held in coutact with the driving-drum, and is rotated thereby to wind the threads; but when a thread breaks or is absent its detector-wire falls and comes in contact with the cam-shaft G, that causes the detector-plate to swing upward, thereby lifting the arm 6 away from the tripping-lever F, which slides under said arm and allows the carrier B to swing toward said plate E or upward, the bobbin H riding over the driving-drum onto the fixed brake support I. Here, as in the construction shown on the right of Figs. 1 and 2 and on the left of Fig. 3, the tripping-lever slides under the trippi ng'arm e of the detector-plate and causes said plate to move farther away from the prismshaped shalt or bar G, by which movement the of said figures; or, as shown in Figs. 4 and 5, it may be wedge-shaped or made tapering from the plate outwardly. Any one of these arrangements may be adopted to insure the removal of the detector-wires from the path 'of the angularbar G after the plate has been tilted by the latter.'

As shown on the left of Figs. 1 and 2, the outward movement of the carrier B is effected bythe weight of the bobbins and that of the free end of the carrier, or by said weights and the attached weight b, and as soon as the lever F is tripped the arms a under the weight described rotate outwardly on their pivot a carrying with them the carrier B, which at the same time swings downwardly on its fulcr-um b. This downward and outward movement causes the bobbin to roll off the drivingdrum 0 onto the inclined supporting brakeplate I, that holds the bobbin and carrier, and by reason of the weight alluded to at once an rests the momentum of said bobbin.

Upon the fulcrum a is hung a leg or stop, J, the lower end of which extends downward in front of the beam A. WVhen the bobbincarrier is tilted outwardly upon the breakage or absence of a thread through the operation of the detector-plate and tripping devices, the cross-bar B impinges against the upper edge of the leg and-tilts the same outward, the car-' rier being held in this position by gravity or by the latter and the additional weight b. When so tilted outward, the longitudinal axis of the leg J lies nearly parallel with the upper face of the beam A", and the cross-bar B of the carrier B above and slightly in front of the pivot a. By lifting the carrier by means of the handle B sufficiently to allow the leg J to swing inward into the vertical position the cross-bar B of the carrier will come to rest upon the leg, and said carrier will be held in a sufficiently elevated position to hold the bobbin clear of the brake-support I and enable the attendant to rotate said bobbin and find and tie the broken or absent threads. By pushing the handle B inward the crossbar B of the carrier will slide over the upper face of the leg J, its inner end dropping down with the bobbin on the brake-surface I. The carrier may now be lifted sufficiently to bring the tripping-lever F against the tripping-arm e of the detector-plate E and allowed to drop, and thebobbin will again lie on the drivingdrum, with the extension a of one or both arms at below their pivotal connection a ,bearing against the vertical face of the beam A, as shown by dotted lines on the left of Fig. 2 and in full lines in Fig. 6.

As shown in Figs. 6 and 7, about wire, D connected with an arm, a, projecting from the arms a of the carrier B, and a horizontal wire supported from the detector-plate, as described in the Letters Patent hereinbefore referred to, may be employed instead of the tripping-lever and arm for tripping the bobbin-carrier, and instead of a bent wire, D a straight wire may 'be employed, said wire being held by a vertical tripping-arm, e, projecting from plate E, as shown in dotted lines, Fig. 6.

Instead of the construction of bobbin-carrier and tripping mechanism therefor hereiuabove described, the construction of carrier and tripping mechanism shown in Fig. 8 may be employed, and this will be found equally efficient. This mechanism is similar to that shown on the left of Figs 1 and 2 and on the right of Fig. 3, except-that the bobbin H is suspended between the detector mechanism and the fulcrum b of the bobbin-carrier B. In this arrangement two bobbins may also be wound upon opposite sides of the drivingdrum, although we have shown but one, and this construction is equally if not more conveniently applied when only one bobbin is wound. In said construction a beam, A extends the full length of the machine above the drum 0, and carries brackets A for the operative mechanism. The arms a are pivoted at a upon the bracket A, and the side bars 12 of the carrier B are pivoted to said arm at b. One of the arms, a, is extended to form a handle, B From the side bars of the bobbincarrier project arms I)", to which the weight b" is attached, to press the bobbin against the periphery of the driving-drum O; and F is a trippinglever or bar pivoted upon the carrier-fulcrum b, and abutting against the tripping-arm e, secured to the detector-plate. A notched stop, J, is pivoted on a pin attached to one of the side bars b of the carrier B. The stop has a stud or projection, j, that limits its downward movement by coming in contact withQthe edge of one of the side bars b. When the bobbin-carrier is released by the tripping devices, as described, and descends, the notch j engages the Wedge-shaped projection or spur is, formed on abracket, K, to support the carrier andhold the bobbin clear of the drum on the inclined brake-support I. When the momentum of the bobbin has been arrested, the bobbin-carrier may be raised until the nosej of the stop J rests upon the end is of the spur k on bracket K, when the bobbin will be clear of the brake I, and may be rotated to find and tie the broken or absent thread end or ends. When the bobbin-carrier is moved back by the handle B, the end of the stop slides off the spur is, leaving the carrier free to swing in toward the driving-drum O, and carry the bobbin into contact therewith. I

As shown by Figs. 9, 10, 11, and 12, which illustrate the detector-plate by an edge view, front, and elevations, and a vertical transverse section, respectively, said plate E has a trunnion or pivot, 0 and a projecting lug or stud, 6 at each end, instead of a pivot only, as described in our Letters Patent here inabove referred to. When the plate E is hung in-its bearings formed in arms A, that project from the beams A A the pin 6 lies under said bearings, and thus locks the plate against vertical movement, leaving it free to swing in the direction ofthe drum, which movement is not sufficient to clear the pins a from under said bearings, ahalfturn of the detector-plate being required for thelatter purpose, when the detector-plate may be lifted out of its bearings, as shown in Fig. 13.

Instead of the locking pins or studs 6", the

plate may be provided at each end with av half-turn toward the drum being required to permit its removal therefrom, the same as with the locking-studs above described. The de tector-plate is provided with longitudinal ribs 6, notched or channeled, as at e, for the passage of the wires E, which wires have a curl or are bent, as at 0 to prevent their being lifted out of the plate by the tension of the thread, and also to hold said wires against tension. The wires are held in their notches by a retaining-plate, E secured to plate E by'a thumbscrew, E.

The threads to be doubled or wound are drawn from cops or from bobbins or swifts arranged in any ordinary manner. Said threads pass each through a slit in a cleaning or guide plate, K, and overa flannel-covered tube, L, to give friction and clean the threads. From the tube the threads pass through the guide hooks or curls e of the detector-wires E, thence over the pulleys M, mounted in bearings formed in arms m, secured to the upper beam, A of the main frame A. From the pulleys M the threads descend through guideloops n, adjustably secured to a bar, N, that has the usual traversing motion for distributing the threads, from which guide-loops said threads pass onto the bobbins, all as plainly shown in Fig. l.

Having now described our invention, what we claim, and desire to secure by Letters Patent of the United States, is

1. The combination, with a driving-drum, a bobbin-carrier, a stop to hold the latter with its bobbinin contact with the former, and tripping devices to trip the stop and permit the carrier to move away from the drum, of a supwith the support and the driving-drum, subsiant-ially as and for the purpose specified.
