MACHINE FOR WINDING BOBBINS.

SPECIFICATION forming part of Letters Patent No. 592,773, dated November 2, 1897. Application filed October 9 1896. Serial No. 608,392- (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. FOSTER, a citizen of the United States, residing at Westfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Machines for Winding Bobbins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for winding bobbins with cotton or silk thread, yarn, &c. either from a single supply-spool or from a plurality of supply-spools, as in the operation known as doublingg and the invention has for its objects to provide a machine of this character in which a new and improved stop-motion mechanism is employed for automatically stopping the winding operation upon the completion of the bobbin or upon the breakage of a winding thread and which improved means for supporting and driving the bobbin during'the winding operation are utilized.

To these ends my invention consists in the winding-machine constructed and operating as hereinafter fully described, and particularly pointed out in the claims.

Referring to the drawings, in which like numerals designate like parts in the several figures, Figure 1 is an'end elevation of a winding-machine embodying the invention. Fig. 2 is a cross-sectional view of one of the winding-heads of said machine, taken at line a; .70 of Fig. 3. Fig. 3 is a front view of said winding-head. Fig. 4 is a detail view of the combined driving-drum and scroll-cam which drives the bobbin and also actuates the traveling thread-guide. Fig. 5 is ,a perspective view of the incline and guide for supporting the cam-bar. Fig. 6 is an under side view of the yoke which supports the bobbin. Fig. 7 is a partial side view of one of the arms of said yoke. Fig. 8 is a side View of the cambar and its attached parts. Fig. 9 is a detail View of one of the two cam-fingers which raise the friction driving-roll out of its engagement with the driving-drum to stop the motion of the bobbin. Fig. 10 is an inner side view of one of the bearings for the friction-roll and a cross-section of the arbor of said roll, taken at line y y of Fig. 11, together with one of said cam-fingers. Figure 11 is a front view of said bearing and one end of the friction-roll. Fig. 12 is a plan view of the arbor for the friction driving-roll and its bearings, the outline of the roll being indicated by broken lines.

lVhile certain features of the invention, hereinafter described, are applicable to winding-machines generally, the entire invention relates especially to that class of such machines in which a plurality of independent winding mechanisms or heads are mounted upon a common frame and are driven from a common shaft or shafts, each winding-head being a duplicate of theothers. In the drawings, therefore, I have illustrated in Fig. 1 an end view of the frame which supports the plurality of windingheads, and for the other views have selected one of the winding-heads simply, it being understood that any desired number of such heads can be arranged side by side upon said frame.

- In Figs. 1 and 2 the numeral 1 designates a portion of one of the vertical end standards of the frame of the machine, and 2 designates horizontal portions of said frame extending from end to end thereof and upon which the parts composing the frames of the individual winding-heads are mounted. Suitably journaled upon said main frame and extending from end to end thereof are a main shaft 3, a driven shaft 4:, and a fixed rod or shaft 5', which are common to all of the winding-heads. The main shaft 3 carries a band-pulley 6, by which motion is transmitted thereto by belt from a suitable source of power, and a sprocket-wheel 7, by which, together with a similar wheel 8 on shaft at and an intermediate chain belt 9, the motion of said main shaft is transmitted to said latter shaft. In lieu of said sprocket-wheels and chain various other forms of means for transmitting motion from said main shaft to the driven shaft can be employed, if desired. To forwardly-projecting brackets 10 at the front side of said frame is hinged a bed 12, bearing upon its outer face a pad 13, of felt or other frictional material, and having projecting therefrom at a right angle thereto the series of posts 14 for supporting the series of supply-spools 15, containing the thread or yarn to be wound upon the bobbins. The posts ll, which are arranged in the usual staggered rows on said bed, have a deereasin g diameter from their outer to their inner ends, as shown, and from the lower side of said bed extends rearwardly a toothed arm 16, which, by engaging one of the portions 2 of the frame, as shown in Fig. 1, enables the bed to be set at any desired angle to the perpendicular. The lower ends of the spools 15, when applied to said posts 14, bear against the frictional pad 13 on the bed, whereby a drag is exerted upon the unwinding movement of the spool to keep the winding thread taut and prevent overrunning of the spool, and by changing the angle of inclination of the bed, as described, the degree of tension thus exerted upon the spool can be varied to suit spools of different sizes and weights and thread of different kinds, the tension increasing with movement of the posts lit toward the perpendicular and decreasing with movement thereof toward the horizontal in an obvious manner. By this simple means I secure a very accurate and delicate adjustment of the tension upon the supply-spools of a windingmachine and avoid the necessity of providing each post with an independent adjusting means.

By making the posts 1&- of a decreasing diameter from their outer toward their inner ends, as described, I cause the tendency of movement of the spools longitudinally of said posts to be toward the lower ends of the latter and against the frictional pad 13, thereby securing an even drag upon the spools at all times. \Vith posts of a uniform diameter from end to end or made tapering toward their outer ends the tendency of the spools is to work toward the outer end thereof and away from the frictional surface at the base of the posts. The inwardly-guiding action upon the spools by the form of posts devised by me is of especial importance in connection with the adjustable form of bed shown and described, in which the tension upon the spools is regulated by changing the angle of the bed, as it is essential to securing a perfect result that the spools be continually in contact with the frictional pad at the base of the posts.

Upon the main shaft 3 are mounted a series of drums 17, one for each winding-head, which drums, as shown in Fig. t, are of slightly less diameter at their central portion than at their ends, and within such recessed central portion they are provided with the cam-groove 18 for a purpose which will presently appear. Upon the driven shaft at are mounted a series of toothed wheels 19, one for each windinghead, the function of which will be presently described.

At the opposite ends of each of the winding-heads are located uprights 20, bolted to the machine-frame, which uprights terminate at their upper ends in open bearings 21, (see Figs. 10 and 12,) in which rest by gravity the ends of the non-revoluble arbor 22 of the friction driving-roll 23, said roll being covered with leather or other suitable material to increase its frictional contact with the drum 17 when transmitting motion from the latter to the bobbin. The open bearings 21 permit the arbor 22 to have sufficient vertical movement to disengage the roll 23 from the drum to stop the movement of the bobbin, and means are provided for automatically securing such result upon the completion of the bobbin or the breaking of a thread, as hereinafter described. To secure a proper lubrication between the friction-roll and its stationary arbor without removing the latter from its bearings, I provide said arbor with a circumferential recess 2% (see Fig. 12) midway between its ends, with a longitudinal groove 25, extending from a point near one end thereof nearly to its opposite end, and with two branch grooves 20, leading laterally from said groove 25 at points near the ends of the arbor. By means of said recess and grooves the lubricant, which can be applied to the open end of groove 25 at any time, is distributed throughout the surface of the arher in such manner as to insure perfect freedom of movement of the roll about the arbor at all times. I thus not only secure perfect lubrication of said roll, but also save much time in the operation of the machine by avoiding the necessity of removing the roll from its bearings for such purpose.

The paper or other tube upon which the bobbin is wound is supported upon a spindle 27, (see Figs. 2, 3, and 6,) carried by a yoke 28, the stem 29 of which enters a socket in the end of a bell-crank lever 30, mounted for a rocking movement upon the stationary rod or shaft 5 of the machine, said stem being secured within said socket by a set-screw 3], whereby it is rendered capable of axial adjustment therein. To the front end of said yoke are secured, by. means of screw-bolts 32, passing through slots in the yoke, two arms 34: and 35, which are thus rendered adjustable to vary the distance between them to receive bobbins of different lengths. The arm 34 of said yoke is extended forwardly to form a finger-piece 36, by which the yoke may be conveniently raised and lowered when desired, and to the under side of said arm is connected by a pivot-point 37 a block 38, which receives and holds one end of the spindle 27. The opposite arm 35 has its under side beveled at its front end (see Fig. 7) and is provided with a notch to receive the free end of spindle 27, which latter when engaged with said notch is held therein by its own resiliency in such manner as to prevent any accidental disengagement therefrom, while being capable of being easily and quickly disengaged by a slight downward pressure upon its free end. The pivot of block 38, as will be noted by reference to Fig. 6, is located at a point in rear of the axial plane of the spin dle, or, in other words, at a point which is eecentric to said plane, and as the result of such arrangement of said pivot it follows that the opposite end of a bobbin wound upon the spindle regardless of its diameter will clear the opposite arm of the yoke in the forward and outward swinging movement of the spindle, as represented by broken lines in said Fig. 6. I thus avoid all danger of fraying or otherwise injuring the thread at the end of the bobbin by contact with the yoke and expedite the operation of removing a wound bobbin from the spindle. During the windin g operation the bobbin carried by said yoke rests upon and is revolved by the frictionroll 23 and the thread is laid in regular layers thereon bya traveling thread-guide 39, which guide has a notch 40 to receive the thread or threads, has a free sliding movement upon a supporting-bar 41, secured at its ends to the uprights 20, and is provided with a projection which enters the cam-groove 18 of the drum 17, as shown by broken lines in Fig. 2, whereby it is given one complete back-andforth movement with each revolution of said drum. As before stated and as shown in Fig. 4, the cam-groove in said drum 17 is located in the depressed portion of the circumferential surface of the latter, and by such construction I entirely obviate any possibility of the oil used to lubricate the projection on the thread-guide in said groove being deposited upon the surface of the friction-roll 23 and by the latter upon the bobbin, thereby doing away with a very common cause of injury to the appearance of the bobbin in this class of machinery.

In connection with the thread -winding means thus constructed I have devised a novel form of stop-motion for automatically stopping the winding operation upon the completion of the bobbin and also upon the breaking of a thread, which will be now described.

To the lower end of the bell-crank lever 30, which carries the bobbin-supporting yoke, is pivotally connected the rear end of a cam-bar 42, (shown detached in Fig. 8,) which bar extends to the front side of the machine and carries at its front end a suitable handle 43, by which it can be conveniently manipulated when necessary. To said cam-bar, near its front end, is connected an adjustable plate 44, by means of a screw-bolt 45, passing through a slot 46 in said plate, whereby the plate is rendered capable of adjustment longitudinally of the bar, and a screw-bolt 47, passing through a tapped hole in a lug 48 on the bar and having its rear end swiveled to said plate, as shown in Fig. 8, serves as a convenient means of securing a very accurate and delicate movement of said plate in both directions by turning said bolt. On its under side the plate 44 carries the cam composed of the two inclined surfaces 49 50, the former or one nearest the front end of the plate being of considerably greater length than the other. The said cam rests upon an incline 51 on a block 52, (shown detached in Fig. 5,) which is secured to one of the parts 2 of the machine-frame, as shown in Fig. 2, said block being provided with the upwardly-projecting lugs 53 54 upon opposite sides of said incline, which serve as lateral guides for the cam-bar. A weight 55, suspended from one of a series of hooks 56 on the side of the cam-bar, causes the cam to bear upon the incline with a considerable degree of pressure, the amount of which can be varied by shifting said weight to different distances from the incline upon the hooks 56. The angle of inclination of the incline 51 corresponds to that of the front side 49 of the cam on the cam-bar, and the frictional resistance of one of said surfaces against the other, due to the weight 55, regulates the degree of pressure with which the bobbin carried by the yoke 28 is pressed against the friction driving-roll, and consequently the compactness of the thread wound thereon; As the bobbin being wound gradually increases in diameter, it. gradually raises yoke 28, thereby rocking lever 30 upon its fulcrum and imparting a forward movement to the cam-bar, which movement causes the in clined surface 49 of the cam thereon to ride forwardly and upwardly upon the incline 51. Such movement continues until the apex between the inclined surfaces 49 passes the upper end of said incline 51, when by the combined action of the inclined surface 50 and the weight the cam-bar is instantly moved forwardly and downwardly'in such manner as to raise the bobbin out of contact with the friction driving-roll, as shown by brokenlines in Fig. 2, thus stopping the movement of the bobbin. The exact instant at whichsuch stopping movement will occur, and consequently the exact size of the bobbin to be wound, is determined by adjustment of the cam longitudinally of the cam-bar by the means before described. A very simple and yet sure and positive means for automatically stopping the winding operation upon the completion of a bobbin of any desired size is thus afforded. I also provide means whereby such forward movement of the cam-bar to cause the stoppage of the winding movement is produced automatically whenever a thread leading to the bobbin is broken, which are as follows:

Pivotally hung upon a horizontal rod 57 at the front side of the machine are a series of hubs 58, each of which has projecting forwardly therefrom a drop-wire 59, having at its upwardly-bent front end a hook to overlap a thread. (See Figs. 2 and 3.) Each of said hubs is also provided, below said wire, with a forwardly-projecting shoe 60, having its under side slightly curved, as shown, while a weighted arm 61 projects upwardly from each hub at an obtuse angle to its'drop- Wire, so that when the drop-wire occupies its normal position, in which it is substantially horizontal, said arm will occupy a position slightly to the rear of a vertical line drawn through the pivotal center of the hub, ,as shown in Fig. 2. The weight of said arm 61 is such that while it permits the front end of the drop-wire to drop instantly upon the breaking of the thread which sustains it in its normal position it materially accelerates such downward movement of the wire as soon as it (said arm) is carried past its center of gravity in a forward direction, thereby insuring against any accidental clogging of the drop-wire or failure, for any reason, to properly perform its function. A cross-wire 62, secured to the frame in rear of the hubs 58, carries a series of loops 63, which by being passed over the arms 61 serve to retain such of the drop-wires as may not be in use at any time in an elevated position, as shown of the two wires at the left in Fig. 3, where they will not interfere with the work of the acting wires, it being understood that as many wires will be provided as will correspond to the maximum number of threads for which the machine is designed, any one or more of which can be utilized independently of the others. A finger-lever 64, hung on rod 57, carries a laterally-projecting wire 65, which passes in front of the series of arms 61 and normally lies out of. engagement with said arms, as shown in Fig. 2, but which serves by an upward swinging movement of said linger-lever to simultaneously move all of the arms and their drop wires to theirnormal position, thus avoiding the necessity of handling each individual drop-wire and expediting the work of the operator. To the side of the cam-bar 42 is pivotally connected, at 66, a drop-lever 67, which terminates at its upturned front end in a horizontal bar 68, which underlies the series of shoes of the dropwires. The rear end of said lever is weighted suilieiently to normally retain said bar 68 in contact with the shoes 60, as shown in Fig. 2, while permitting the combined weight of a drop-wire, its shoe, and its arm 61 to depress the front end of the lever whenever the dropwire is released by the breaking of its thread. Projecting downwardly from the front end of said drop-lever is a toe 69, which normally lies just out of contact with the toothed wheel 19 on shaft 4, before mentioned, but which when the lever is depressed by the breaking of a thread, as just described, immediately engages a tooth of said constantly-running wheel, thereby causing the latter to impart an instantaneous forward movement of said lever and the cam-bar and carry the apex of the cam 49 50 past the upper end of the incline 51, thus causing the stoppage of the winding operation in the manner previously described.

The drop-lever is provided on its under side with the curved recess 70, (see Fig. 2,) which commences immediately in rear of the toe U9 and terminates at a point opposite the apex of the cam 40 50, and when said lever is depressed by a released drop-wire, as just described, the wall of said recess engages the upper end of the lug 54: on the block 52. Said recess is of sufiicient depth to permit the toe 69 to engage a tooth of the wheel 19, as described, when the cam-bar occupies its normal position, (shown by full lines in Fig. 2;) but in the forward movement of said bar and lever caused by said wheel the action of said lug against the wall of the recess is such as to lift the toe out of engagement with the wheel simultaneously with the arrival of the apex of cam 49 50 at the end of incline 51, thus permitting the incline 50 and weight 55 to complete the forward movement of said parts in the manner first described. During such continued movement of the cambar the drop-lever is maintained in its normal position by the lug 54, as shown by broken lines in Fig. 2, and its bar 08 by its engagement with the shoe of the drop-wire which has just caused the stoppage of the winding operation again raises said wire to its normal position, where the operator can engage the reunited thread with its hook quickly and conveniently. In Fig. 3 the dropwire at the extreme right is represented as having dropped by the breakage of its thread (shown by a broken line) to stop the winding operation, as just described, and at the instant before the toe on the drop-lever engages the toothed wheel 19.

After any stoppage of the winding operation the parts of the stop-motion mechanism above described are restored to their normal position by grasping the handle 43 of the cam-bar and moving said bar to its rearmost position, thus returning the bobbin to its engagement with the friction driving-roll. As such action requires the use of one of the operators hands, however, and as the use of both hands may be required to manipulate a number of threads in starting a bobbin, I have provided means whereby such restoration of the parts to their normal position does not of itself cause the bobbin to start its winding movement, such result being secured by another agent, which is as follows: A table 71, having at its ends projecting lugs 72, which enter suitable sockets in the uprights 20, is thereby supported in an erect position in front of the driving-drum in such manner as to be capable of a limited rocking movement upon said lugs as a center. The wind ing threads are led across the upper portion of said table, which is inclined rcarwardlytoward the friction driving-roll, as shown in Fig. 2, to the traveling guide. At its lower end the table is adjustably connected by a screw 73 to the upper end of a lever 74, pivotally supported upon the frame, the lower end of which lever is adapted to be engaged by a pin 75 on the drop-lever (37 in the forward movement of the cam-bar to stop the winding operation and thereby actuated to rock the table to the position shown by broken lines in Fig. 2. Projecting rearwardly from the table above its pivotal center are two arms 76, which lie adjacent to the opposite ends of the drum 17 and carry at their ends forwardly-curved fingers 77, which extend ICC beneath and adjacent to the two ends of the arbor 22 of the friction-roll, as represented in Fig. 10. The curvature of said fingers 77 is such that when the table is rocked to the pos1t1on shown by dotted lines in Fig. 2, as just described, they will lift the arbor 22 in its bearings sufficiently to disengage the frictionroll from the drum and maintain it in such pos t on until the table is again returned to the position shown by full lines in said Fig. 2. It follows from such construction that the action of the stop-motion mechanism to stop the winding operation from either of the two causes mentioned will also infallibly cause the disengagement of the friction-roll from the drum and that, having restored the parts of the stop-motion mechanism to their normal poslt on by manipulation of the cam-bar, a return rocking movement of the table 71 is required to cause the starting of the winding operation again. Such movement can be imparted to the table by slight pressure against its upper portion, thus leaving the hands entirely free to manipulate the threads.

A gravity-stop 7 8, (see Fig.'2,) which is plvotally connected to the inner side of arm 34 of yoke 28, bears against the bobbin 79 in such manner as to prevent any backward revolution thereof, while offering no impediment to its forward movement.

The operation of the winding-machine thus constructed will be clearly apparent from the foregoing description and need not be repeated.

It will be noted that the improvements devised by me all tend to secure greater expedition and convenience in the operation of the machine and to improve the character of the work done by it, and that these results are secured in a simple but entirely effective manner.

It will be obvious that various modifications in the exact details of construction herein shown and described can be made without departure from the spirit of the invention.
