Patented in England March 25, 1893, No. 6,381; in France March 25, 1893, No. 220,702; in Belgium March 25, 1893, No. 104,051; in Germany March 25, 1893, Nos. 73,859, 74,497, 74,732, 75,022, 76,456, and 76,481; in Austria-Hungary March 25, 1893,1Io. 17,999 and No.l 90,408,

Be it known that I, SIMON W. VVARDWELL, Jr., a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for finding Shuttle-Oops, of which the following is a specification.

My invention, which has been patented in England March 25, 1893, No. 0,381 g in France March 25,1893, No.220,702 in Belgium March 25, 1803, No. 104,051; in Germany March 25, 1893, Nos. 73,859, 74,497, 76,456, 76,481, 75,022, and 7 4,7 32; in Austria-Hungary March 25, 1893, No. 17,999 and No. 90,408, and in Italy March 25, 1893, No. 33,778/267, relates to apparatus for winding cops or balls of thread, yarn, ctc.; and my invention consists of certain improvements upon the apparatus set forth in my Letters Patent N o. 480,157, and fully set forth hereinafter and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my improved apparatus for winding cops or balls. Fig. 2 is an enlarged elevation of part of the apparatus sufficient to show one winding-shaft and its connections. Fig. 3 is a plan of the parts shown in Fig. 2. Fig. 4 is a transverse section of the parts shown in Eig.'2. Fig. 5 is a transverse section on the line 5 5, Fig. 3; Figs. G to 10, details of the automatic stop device.

The cop-shaft 1 is provided with an expansion-spindle a, so that when the cop-tube is placed upon the said spindle the spindle may be expanded to hold it in place,and the threadguide hole is in an arm 2, which is pivoted to a carrier 3, the latter being a hub upon a rockshaft 15, which derives its motion from another rock-shaft, 4, having a forked or slotted arm 7, into the fork or slot ec of which extends a pin 5 from the rocking carrier 3. The rockshaft 4 is driven from a cam-wheel 13, into the cam-groove of which extends a stud 12 carried by a swinging arm 10. Another stud, 9, extending from the stud 12 into a slot in an arm 8, which latter is secured to the shaft 4.

The cam thus imparts a reciprocating motion to the arm 8 and a rocking motion to the shaft 4, and the arm 7 on the latter imparts a rocking motion to the carrier 3, which carries the arm 2, having the thread-guide at the upper end in the form of an opening or hole constitut-in g the thread-bearing.

The thread-guide arm 2, Fig. 2, is pivoted to the carrier 3, so as to swing to and from the cop-shaft 1, whereby, as the size of the cop increases, the arm 2 is thrown back, and this movement of the arm is the means of' adjusting the pin 5 in the slot m, so as to gradually reduce the lateral reciprocating motion imparted to the guide from the shaft 4, thereby building up a cop gradually contracting in width from the hub toward the out-er edge.

It will be seen that the thread-bearing of each guide is so arranged that the thread is delivered directly from the guide to the face of cop-that is, there is practically no play between the point of delivery of the thread from the guide and the poin t where the thread reaches the cop. This is a matter of the utmost importance, because it has proved in practice that if there is an opportunity for the thread to play it will not deliver properly onto the cop, and the latter will begin to build irregularly and the irregularity will increase until the character of the cop is entirely destroyed. Further, if there is any such play and the guide is reciprocated with extreme rapidity, as it is in some instances, then the thread will be thrown out of place.

Different means may be employed for shifting the position ofthe stud 5 in the slot 0c, accordin g to the position of the arm 2. Thus the stud 5 may be carried by a sliding block 0, mounted to slide in a slot in the carrier 3, and pressed upward by a plate-spring 16, and the bl ock 6 has a forwardly-inclined edge y against which bears a transverse edge or shoulder .e of theV guide-arm 2. lVhen, therefore, the said guide-arm is thrown back in thedirection of its arrow, the shoulder z, bearing on the inclined edge y, causes the block (i to be thrown downward to a greater or less extent, carrying with it the stud 5, thereby re'ducing the distance between the stud and the axis of the shaft 4, and consequently reducing the throw imparted to the carrier 3 by the movement of the arm 7 on said shaft.

The carrier 3, Fig. 4, and the thread-guide arm 2 are slotted for the passage of the shaft 4, as shown.

The expansion holder a for the cop-tube X may be made in different ways. I prefer, however, to make it in the form of a longitudinally-splitsleeve a, Fig. 5, upon a tapering end of the shaft 1 and with a circular head 19, having an annular groove Y), and into the said groove b enters a lug 2O on a lever 2l, which may be swung outward to carry the split sleeve forward and permit the members thereof to contract and receive the cop-tube, and then may be carried back to the position shown in Fig. 5, expanding the sleeve in the cop-tube and heldin g the latter firmly in place.

In order to wind the cop in the manner described in my Letters Patent before referred to, it is necessary to impart such a relative difference of movement to the cop-winding shaft and to the thread-guide that the thread when brought to either end of the cop will be laid either just back of or just in advance of the thread previously laid at that point-that is, there is not only a complete revolution of the cop to each reeiprocation of the threadguide, but also an increment of movement sufficient to cause the new thread to be laid in advance of the position it would otherwise occupy, or instead of a complete revolution there is at the terminationv of each movement of the guide a partial revolution of the cop sufficient to permit the new thread to be laid back of that previously laid. I secure this difference in the relative movements by connecting together the cam 13, which drives the thread-guide and the sh aft 1, which drives or carries the holder for the cop, by means of gears so constructed that one or other of said gears may have either a slight increase or a slight decrease in its movement in respect to the others. Thus the gear-wheel 23 upon the shaft 1 is geared through an intermediate gear-wheel 24 with a gear-wheel 25 carried by but turning upon the shaft 29, to which is secured the cam 13. The shaft 29 carries a yoke 22 in which turns a shaft 24 carrying a pinion 39 that meshes with the teeth of a gear 2 7 upon an annular flange 20 of the gear-wheel 25.

A friction-wheel 31 upon the shaft 24 is in frictional contact at its periphery with a stationary plate 32, and when the friction-wheel 31 is in a position coincident with the axis t of the shaft 29, the revolution of the shaft 29 will not impart any corresponding revolution to the gear 25 or to the connected frame. When, however, the friction-wheel 3l is shifted to one side of the axis t, then it will travel upon the plate 32 as the shaft 29 revolves, and consequently the pinion 30 will travel upon the gear 27 and impart either more or less motion to the gear 25 than the shaft 29 has, so that the gear 25 either revolves to a sli ghtly-greater extent than the shaft 29 or to a sli ghtly-less extent than said shaft, giving the movement before referred to. By making the wheel 31 adj ustable upon the shaft 24, the degree of this movement may be varied to any desired eX- tent so as to secure the requisite adjustment with the greatest nicety.

l do not here claim the construction of dcvice for securing the requisite variation inthe movements of the cop-holder and threadguide, as the same constitutes the subject of a separate patent, No. 506,959.

It will be understood that it is exceedingly desirable in winding small cops orbobbins for sewing-machines to avoid the use of a multiplicity of winding apparatus, while at the same time it is necessary to impart the requisite movements and variations of movements before described to each spindle carrying a cop-tube and its coacting thread-guide. In order to secure this desirable result, 1 cembine with a series of cop-winding shafts 1 and with a series of thread-guides a single regulating device ef the character described, or of any other suitable character that will impart the requisite variations of movement. One means of effecting this is illustrated in Fig. 1, where it will be seen that the shafts 4 and 15 are prolonged so that the shaft 4 carries a series of arms 7 and the shaft 15 a series of threadguide carriers 3, and that there is a series of shafts l.

The series of shafts 1 are connected so as to rotate together by means of -intermediate gears, as shown and indicated, while the single cam 13 drives both of the shafts 15 and 4 and imparts the requisite movement to the various thread-guides in their proper relation to the rotation of the cop-shafts.

It has been found that if the tension upon the thread is maintained uniform throughout the winding of a cop-that is, when the thread is of elastic material, especially such thread as silk-the outer layers er windings compress the inner layers or windings so that the sides of the cop are forced outward. I avoid this by gradually reducing the tension as the size of the cop increases. One means of effecting this is by applying a frictionbrake to the tension device and gradually reducing the force of this brake. Thus, I carry the thread, Fig. 2, around a friction-brake wheel 33, having a peripheral groove to receive the thread, and against the shaft or hub on the shaft 45 of said friction -wheel bears a brake 35 at the end of a lever 34. A movable weight shown in the form of a heavy roller 37 rests upon the lever 34, and is caused to travel nearer the fulcrum of the latter in proportion as the size of the cop increases. Thus a pin 44 on a lever 42 pivoted at the lower end bears against the guide-arm 2, so as to be swung back as the said guide-arm is swung back, and a pin 41 upon the lever 42 bears against the edge of a pivoted lever 39, forked at the upper end and having a slot in each fork to receive the shaft 47 of the IOO IIO

weight 37. As the guide-arm 2 swings back it carries with it the levers 42 and 39 and the weight 37, so that as the size of the cop increases and bears back the guide-arm 2 the weight 37 is carried nearer to the fulcrum of the lever 34, and the effect of the frictionbrake decreases, relieving the thread of tension.

Itis desirable to arrest the movement of the machine the instant that a cop is filled. I therefore provide means whereby this may be automatically done. Thus each shaft 1, Fig. 4, instead of being rigidly connected with its gear 50, is connected through the medium of a clutch consisting, as shown, of a tapering hub 51, which is upon the gear and with the latter turns loosely upon the shaft 1, anda movable clutch-piece 52 splined to the shaft 1, having a socket to receive the hub 51 and tapering to correspond therewith and with an annular shoulder Iv, the piece 52 being pressed toward the hub 51 by a spring 54, and when the tWo parts are in contact the shaft 1 turns with the gear 50; but when the part 52 is thrown out the shaft will remain stationary while the gear 50 turns. A lever B havingI a handle cl and a cam-arm 55 may be thrown in one direction to the left, Fig. 5, to bring said arm against thc shoulder o and throw out the piece 52 to the left, a spring 56, Figs. 4 and 5, tending to throw the arm 55 in this direction. rI`he arm 55 has a shoulder or lug 57, Figs. 5 to lO, which engages with a suitable detent, as a spring 5S, and over the latter extends an eccentric or cam 59 upon a shaft carrying an arm GO, Figs. 4 and 7 that terminates in the stop t.

The stop is in such a position that when the thread-guide arm 2 is carried back to a sufficient extent by the completion of the bobbin a contact-piece s upon the said arm will, as the arm swings inward, strike the stop t, rock the arm 60 and its cam 59 in the direction of the arrow, Figs. 4 and 7, and bring the said cam to bear upon and depress the spring 53 to carry it from the shoulder 57, when the spring 5G will force down the arm 55 of the lever B, and thereby force back the piece 52 of the coupling and uncouple the shaft 1 from the gear 50.

In order to reset the parts, I make use of the cam 102 on the end of the lever d, which passes through a slot i0/ in the arm 55, the cam 102 making contact with the spring or detent 58 when the handle is swung to one side, depressing the spring, and the handle then takes a bearing on the arm 55 and swings the latter. The pins 9 12 are upon a slide adjustable on the arm 10, so as to vary the extent of movement imparted by the cam 13 by carrying the slide nearer to or farther from the axis of the arm 10.

It will be evident that while I have shown a series of vibratin g reciprocating carriers for the thread-guides, said carriers may each slide in straight lines, as in the machine constituting the subject of my Letters Iatent No.

506,959. Although I have shown in this application some devices for securing an increment of movement, (shown in my aforesaid Patent No. 506,959,) I do not herein claim the same except in the particular combinations set forth.
