To all whom itmay'concern:

Be it known that I, ALBERT MoRLEY,a citiin the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bobbin-finders for Sewing- Machines, which are. fully set forth in the fol-. lowing specification, reference being had to the accompanying drawings, in which- Figure 1 is aside elevation of a bobbin winder embodying my invention; Fig. 2, a plan View of the same; Fig. 3, a vertical section of the same, taken on the line 3, 3, of Fig. 2 lookingin the direction of the arrows thereon; Fig. 4, a detail Section, taken on the line 4, 4, of Fig. 1; Fig. 5, a detail section, taken on the line 5, 5, of Fig. 1, Fig; 6, a detail plan section, taken on the line 6, 6, of Fig.

Figs. 4, 5,6, 8, 9, 10, 11 and 12 are upon one scale, but enlarged from .thatj ust mentioned; and Figs. 7,13 and 14 are upon one scale, but still further enlarged.

.My invention relates tomachines for winding bobbins for sewing machines; and is in tended to provide a machine which may be attached to the table of the sewing machine, or some other convenient support, where it may be driven either from the driving shaft of the' sewing machine, or any other device adapted to communicate the required motion to the winder.

'I will proceed to describe in detail the construction and operation of a machine in which I have embodied my invention in practical operative form; and Will then point out more definitely in claims the improvements which I believe to be new and wish to protect by Letters Patent.

a disk of a size to hold three bobbins. perforations, 0', through the disk must be 10- In the drawings, A represents a supporting base which is adapted to be fastened to the table, or any other suitable support for the machine. From this base at one side rises a post or standard, a, which carries at its top a band-Wheel,B, the shaft, b, of which is mounted in a suitable bearing on the post and has at its other end a small band-pulley, b. This wheel B is the drive-wheel of the winder; and motion is communicated to it from any suitable power shaft, by means of a band, B On the opposite side of the base there is also a the machine, where it projects considerably beyond its hearing. The bobbins are mounted on this disk by the following devices:The disk is perforated at suitable intervals, according to the number of bobbins which it is to accommodate.

In the drawings the machine is shown with These cated in the same circle, which is somewhat within the circumference of the disk; so that each bobbin in turn will be brought into the same required position, as the disk is rotated.-

A sleeve, 0 is inserted in each one of these holes through the disk, being passed through from the back side of thelatter and provided with a flange, 0 on that side of the disk, which sets againstthe latter and fixes theposition of the sleeve. The sleeves extend somewhat beyond the front face of the disk, as seen in Fig. 10 of the drawings; and are fastened in position by binding-screws, c,set in from the circumference of the disk against the sleeve, as seen in Fig. 12. In each of these sleeves is mounted a short hollow shaft,

D, being inserted at the front end of the sleeve, 7

where it is provided with a flange, cl, which wheel; and its shaft has a long bearing a through which it extends to the other side of ceive the lever for this purpose.

will stand a little under the latter, as seen in Fig. 3, so that the driving band, passing down at the back of the wheel B,-will pass over the pulley standing in this position, as seen in said Fig. 3 and, therefore, when the band is driven, this pulley will be rotated and thereby revolve the bobbin shaft to which it is attached.

In the front end of the hollow spindle shaft is set a short plug, (Z from the front end of which projects a still smaller stud or spindle, (Z which constitutes the journal or pin on which the bobbin, E, is mounted. The bobbin is held on its spindle by means of a springlever, e, which is arranged within the hollow bobbin shaft, and is pivoted to the plug d which is slotted at its rear or inner end to re- The slot in the plug also extends out through the bobbin spindle, opening on one side thereof, so as to provide a groove, (1 within which the outer end of the lever extends. The outer edge of the lever e in this recess (1 protrudes a little from the slot, when free to move under the action of its spring; and it is preferably inclined or beveled slightly in each direction, so as to make a small bearing point or edge, e. At the rear end of the tubular shaft D, a spring, 6 is set under the tail of this lever, as seen in Fig. 10 of the drawings; and arranged so that it will operate to vibrate the lever in adirection to cause the front edge to protrude from the slot in the spindle,just described. When the bobbin E is slipped upon its spindle, as seen in Fig. 10, the lever will yield on account of the spring, so that the bobbin can easily be mounted on its spindle, but the forcing outward of the lever by the action of the spring, just described, will operate to hold the bobbin in place. This device enables me to use bobbins of different sizes; for, even though the bobbin is a little larger than the spindle, the lever will retain it in its proper position. The plug (Z is held in its position in the shaft by means of a binding-screw, d inserted through the end of the shaft, as seen in Fig. 11.

In the head of the tubular shaft D and just below or outside of the plug (P, a circular recess, (1 ,18 sunk. This recess is for the reception of a small plug, f, which is set in the recess to which it is fitted. This plugfis for a cutter and clamp which severs the thread at the proper time and catches and retains the spool end ready forthe next bobbin. The body of the plug is cutaway on one side atits front end to provide a flat seat, f and at its rear end a slot or recess, f is cutin some distance toward the front end of the plug.

The knife or cutter, f, is provided with a shank, f which fits the slot in the rear end of the plug and is pivoted thereto, as seen in Fig. 13 of the drawings. The front end of the cutter is a kind of broad foot, f which is adapted to rest upon the seat f. This foot has a notch, 1, cut in its forward end, the sides of which are beveled and slightly flaring; so that at the rear end of the notch, the lower edge becomes a sharp cutting edge, as shown at f in Fig. 13. The outer prong of this foot is beveled slightly on the lower side of its front end; and the said seat immediately below is correspondingly beveled, so as to make a slight opening or notch, as seen in Fig. 14 of the drawings, for facilitating the entrance of the thread between these two parts. A small coiled spring, f, is set in the recess in the rear end of the plug between the body of the latter and the tail of the cutter, as seen in Fig. 10 of the drawings, and operates to hold the foot of the cutter down upon its seat, but'providingfor a slight yield:

ing of the latter upon its pivot to permit the thread to enter between the cutter-foot and the seat when required. This cutter plugf is set into its recess with the cutter end outward, as seen in Figs. 10 and 11 of the drawings; and is fastened therein by a binding screw, f".

\Vhile one of the bobbins is being wound or filled, it is necessary, of course, that the disk C be stationary. For the purpose of thus securing the disk in its required positions, notches, e, are cut in its periphery,one opposite each bobbin and each having its front wall slightly beveled for facilitating the entrance of a stop, presently to be described while the other is perpendicular, the rotary movement of the disk being in the direction indicated by arrows in the drawings.

On the base A, just behind the disk 0, is a short stud or standard, a which is slightly inclined forward toward the disk. A recess, a is cut down into this standard at an inclination corresponding to the radius of the disk, in the plane of which it is situated. A short bolt or stop, G, is fitted into this recess, having a spring, g, placed back of it; which, of course, operates to throw the stop outward. The outer end, which projects beyond the standard under the normal effect of the spring, is cut down to form a short lug, g, adapted to fit the notches in the periphery of the disk, with which it is caused successively to engage under the action of the spring. Obviously, when this bolt thus engages with one of the notches in the disk, it will securely fasten the latter in the position to which it has been turned, and will hold it in such position until disengaged from the notch. To provide for such disengagement, a pin, 9 is secured to the front side of the bolt and passes out through a slot, M, in the front portion of the standard, a as seen in Fig.3 of the drawings. Evidently, whenever this pin is depressed, the bolt will be withdrawn from engagement with the disk; thereby unlocking the latter. This unlocking of the bobbin disk or holder is ef' fected automatically upon the filling of the bobbin, in the following way. In Figs. 1 and 8 of the drawings, the disk is represented in position just as it has been stopped after its intermittent movement to carry one bobbin out of position and bring another into position for Winding. The bobbin marked E has just been filled, while the one marked F. has just been brought into position for filling. In the base A is mounted a short rock shaft, H, directly underneath the bobbin disk and near its inner end there is fastened upon this shaft an arm, h, which extends backward underneath the disk until it rests upon the pin g as seen in Figs. 1 and 7 of the drawings. A spring, h, is coiled around this shaft between the hub of the arm h and the side of the base, being attached at one end to the former and at the other to the latter; and so arranged as, normally, to throw the arm h'up. Now it is evident that if this shaft H is rocked in a direction to turn this arm h downward, it will depress the bolt Gr and thereby unlock the bobbin disk; and that such a movement of the shaft must be against the action of its spring. A collar, I, is fastened upon the outer end of this rock shaft and has a projection, t', at its rear, in which is mounted a cam pin, 1'', that extends through the projection and somewhat beyond the latter on the inside thereof. The inner end of this pin, beyond its bearing in the collar, I is enlarged and cutaway upon its upper side to present a flat face, P, as seen in Fig. 7 of the drawings. A short arm, 2' is fastened to the outer end of the cam pin, by which it may be oscillated. This arm is elastic and carries upon its outer end a pin, 2', the inner end of which is adapted to enter one of two or more holes, t provided in the outer face of the collar 1, whereby the cam may be set in the position to which it may be adjusted. Inside of the collar I, a lever, J, is mounted loosely on the rock shaft H and extends upward even with the bobbin when in the position of winding; as shown by the bobbin marked E in Figs. 1 and S. This lever is provided at its foot with a toe, j, extending rearward, over the inner end of the cam pin 2" just described; hence it is evident that any backward vibration of the lever will depress this toe, which acting on the said pin will rock the shaft H in a direction to depress the arm h on its inner end. The upper end of the lever J is provided with a cam projection,j, which is set inward so as to be brought into the same plane with the bobbin, and then projects forward between the flanges or sides of the bobbin against its central body or barrel, as seen in Fig. 8 of the drawings, being held up in this position by the rock shaft H on which it is mounted. In order to prevent this lever being thrown forward too far, it is provided at its lower end'with a shoulder, j opposite to the toe j, immediately below which is a lug or stop, a, on the base, against which the shoulder on the lever will strike and thereby arrest the forward movement of the latter. Now the bobbin is wound under the slight pressure of the cam j at the upper end of the lever J, resting constantly against the thread, so that, as the bobbin is gradually filled, the

cam will be gradually pushed back by the wound thread, thereby rocking the shaft, as already described, so as to depress the arm on the end of the shaft to unlock the bobbin disk,

the parts being constructed and arranged to effect this result when the bobbin is full. The adjustable cam on which the toe of the lever J acts, provides for the use of this tripping device with bobbins of different sizes.

From the description above, it will be seen that the shaft H is rocked to depress the locking bolt G by the downward pressure of the the lever is pushed back far enough to unlock the disk. Precisely this result is obtained by adjusting the cam to different positions. If it isset in the position shown in Fig. 7 of the drawings, with its thicker portion thrown up under the toe, the lever will be thrown for-' ward slightly, so that less movement will be requiredv for tripping the lock and so it is adapted to small bobbins. Now, if the cam be turned so that its fiat face will be uppermost, and the toe will rest directly upon this face, it is evident that the lever will have more backward movement to effect the trip and hence under this adjustment it is adapted to bobbinsof larger size.

As soon as the bobbin disk is unlocked, it is rotated by a device which I will now describe. A large band wheel, K,-is mounted loosely on the outer end of the shaft 0 opposite to the bobbin disk; being grooved forthe accommodation of the band. The hub, 70, of this wheel is considerably enlarged, and on its inner face has a recess, 7a, which is adapted to receive a friction Wheel or hub, 0 fixed on the shaftc just outside of its bearing a as seen in Fig. 4 of the drawings. A spring, 10 is coiled around the extreme outer end of the shaft 0 outside ofsthe hub of the wheel K, being held on the shaft by means of a suitable collar, it as seen in Fig. 2. This spring, of course, acts to hold the wheel K up to engagement with the friction hub, thereby making a kind of friction clutch between the two, which is sufficient to cause the movement of the bobbin disk with the rotation of the wheel K when the disk is unlocked,but, when the latter is locked, as already described, the force of the bobbin.

of the spring is not so great but that the frictional surfaces move easily upon each other and permit the wheel K to rotate constantly. This wheel K- is rotated by means of a band, L, which passes over the band pulley b on the shaft b and around a small pulley, Z, arranged immediately below the former and suitably mounted on the base. This lower wheel stands in a little under the wheel K so that the band L on its inside path will be applied to the periphery of the wheel K at that point and so rotate the latter by the motion which is communicated to the band through the drive wheel B. This rotation will, of course, be communicated to the disk 0 the moment the lock of the disk is tripped, and will continue until the next notch in the periphery is brought into engagement with the locking bolt,that is, the movement of the disk is the distance from one notch to another. This movement brings the full bobbin E into position near the lock, as shown in Figs. 1 and 8 of the drawings; and at the same time brings a new empty bobbin E into position for winding, as seen in the same figures; and then the disk is stopped again; but the thread is not yet cut, and is run out with the full bobbin, as indicated in the two figures just mentioned. It will be understood from the description already given that when the bobbin marked E is brought into winding position, as just stated, its driving pulley D is also brought into contact with the band B, as shown in Fig. 3; so that the rotation of the bobbin begins at once.

At the first movement of the bobbin E the thread is cut; as will now be described. Then the thread is carried down with the full bobbin in a straight line, it is not in position to be taken by the cutter, being outside of the plane of the latter. In order to bring the thread into such position that the cutter will surely take it as soon as the bobbin shaft begins to revolve, a thread placer, M, is employed. This placer is in the form of a bell-crank lever, pivoted to the base so as to vibrate at right angles to the plane of the bobbin disk, as seen in Fig. 5 of the drawings. The perpendicular arm m, of this lever extends up to the head of the bobbin shaft and is provided at its upper extremity with an enlarged flat hand, m, which has aslight rib or flange m on its rear upper corner. horizontal t1i11,ln of this lever extends inward under the disk (I; and underneath itsinner end is set a spring, M, arranged in a suitable seat in the base. This spring operates normally to throw the lever outward beyond the plane In this position, the hand at the upper end of the lever stands outside of and opposite the thread as it is carried down by the full bobbin; and it is evident, therefore, that if the lever is vibrated inward it will carry the thread inward with it. In order to effect this movement, cams, N, are fastened to the disk; being arranged one for each bobbin put in its place.

The

bobbin and a little behind the same, as seen in Fig. 1 of the drawings. These cams are of such size and shape that as they pass over the horizontal arm of the thread placer M, they will depress it against the spring, thereby vibrating the placer inward and so carr ing the hand inward, thereby placing the thread in against the head of the bobbinshaft, as seen in Figs. 4 and 5 of the drawings; this is also the position intended to be represented in Fig. 8. The relative arrangement of the parts is such that this movementot' the placer is effected just before the bobbin disk stops and the thread is then carried in so far that it will certainly be taken by the notched cutter, already described. After this placing :of the thread, it lies immediately in front of the cutter, as seen in Fig. 8, which is intended to represent the position of these parts just before the revolution of the bobbin commences. The construction of the horizontal arm m and the cams N is such that the latter remains in contact with the arm when the thread, which will thereby be drawn inj ward between the cutter and its seat, thereby clamping the thread to the head of the shaft, and at the same time severing the thread as soon as the edge at the inner end of the notch is reached; which operation will be understood from examination of Fig. 0. The full bobbin can now be removed and an empty The end of the main thread is, however, clamped to the head of the bobbin shaft and, of course, rotation of the latter fills the new bobbin. The placer remains in the position described,until the disk starts again, when the cam N immediately passes off from the horizontal arm m and,

under the action of its spring, the placer is vibrated outward at once. Atthe angle of this placing lever, there is provided a toe, m, which extends down a little way outside of the base, as seen in Fig. 5, and serves as a stop to limit the outward throw of the lever; and a projection or lug m may be provided on the under side of the horizontal arm which limits the inward throw of the same lever by striking against the bottom of the base. For

the purpose of properly guiding thethread to the bobbins, an inclined standard, 0, is fasfrom the principle of my invention.
