JAMES C. POTTER, OF LOWELL, ASSIGNOR TO THE ATHERTON MACHINE COMPANY, OF TEWKSBURY, MASSACHUSETTS.

SPlNNlNG ACl-HNE.

SPECIFICATION forming part of Letters Patent No. 392,524, dated November 6, 1888.

Application filed December 31, 1885.

.To 60% whom it may concern..-

Be it known that I, J AMES C. POTTER, of Lowell, in the State of Massachusetts, have invented certain new and useful Improvements in SpinningMachines for the Manufacture of Yarn or Thread from Cotton or other Fibrous Materials, of which the following is a specification.

My invention, while designed more particularly with reference to the needs of speeders, is applicable also to analogous machines, and it has particular relation to what is termed the builder motion-that is to say, the movements by which the bobbins are wound. It is of course requisite to give determinate shape to the bobbins, and this, in connection with the fact that the bobbins gradually increase in diameter as they are wound, renders it necessary to provide for differential motion, as it is termed, of the spindles, as well as for agraduation of the up-and-down movement.

My invention consists in certain improvements,hereinaft-er specifically described,in the mechanism by which these motions are controlled and determined, my main object being to obtaimas far as practicable, a positive connection between the belt-fork which governs the-position of the belt on the cone-drums and the controlling devices which regulate both the action of said fork as well as also the upand-down movement of the spindle-rail, and also to provide meansby which the movement can readily be adjusted for the production of one, two, three, or more hank bobbins.

My invention can best be explained and understood by reference to the accompanying drawings, prior to the description of which I would remark that to a better understanding of the invention I have deemed it advisable to represent to extenso that portion of a speederframe containing the parts more immediately affected by my improvements, omitting, however, some of the shafting, gearing, &c.,which, while found in practice on said portion of the frame, are not essential for the purposes of this specification.

The portion of the machine referred to is of too great length to be adequately illustrated on a single sheet, and it is therefore embraced in three sheets-Figures 1, 2, and 3.

"movement of the flap-lever.

Serial No. 187,236. (No model.)

The view in these three figures is a rear elevationthat is to say, an elevation from the side opposite that on which the spindle and fliers are situated. In viewing these three figures, Fig. 2 should be placed in the center, with Fig. 1 on its right and Fig. 3 on its left. Fig. 3 has on its right a portion of the gearing represented in full at the left upper end of Fig. 2. Fig. 4

is a side elevation, partly in section, of the reversinggearing shown on the left of Fig. 3, looking at the same from the right of the figure, the cross-framing of the machine being broken away in part, so as to disclose the gearing. Fig. 5 is a plan of a portion of said 6 5 reversing-gearing with the cross-framing in section. Fig. 6 is a vertical cross-section through the conedrums to the right of the belt-fork in Fig. 2, showing in side elevation some of the motiontransmitting gearing, with a portion of the cross-framing broken away. Fig. 7 is a side elevation, on enlarged scale, of

a portion of the reverse-shaft and the shoe and parts connected therewith for controlling the throw of said shaft, the actuating-shaft of the 7: shoe being represented in crOsssection. Fig.

8 is a plan of said parts. Fig. 9 is a plan, partly diagrammatic, of the flap-lever, hereinafter referred to, and the parts in connection with which it operates. Fig. 10 isa crosssec- 8c tion through that arm of the flap-lever which carries the tapered or wedge-shaped retainingpiece. Fig. 11 is an enlarged side elevation, partly in section, of the reverseshaft-controlling device and adjoining mechanism, looking at them from the right in Fig. 1. Fig. 12 is a rear elevation, partly in section, of the device for adjusting both the belt-fork and also the dogs carried by the slide for controlling the Figs. 13, 14, 15, 9o 16, 17, and 18 are enlarged views, to be hereinafter referred to, of details of the mechanism illnstrated in Fig. 12.

A is the driving or flier shaft, which drives the fliers A in the usual way, and also com- 5 municates motion to the other parts of the machine.

B is the spindle-shaft, which drives the spindles B in the usual way. The differential motion of said spindle-shaft, rendered neces 10o sary by the increase in the diameter of the bobbins during the winding operation, is accomplished as follows:

Gear 1 on driving-shaft A drives an intermediate, 2, which in turn drives gear 3, fast on the shaft of cone-drum 4. Gone 4 drives reversed cone 5 by belt 6. On the axle of cone 5 is gear 7 ,which meshes with and drives the compound intermediate 8 9. 9 drives gear 10, which is fast on shaft 11. On said shaft 11 is another gear, 12, which drives gear 13, fastened on shaft 14-, and on shaft 14 are carried a pair of beveled gears, 15, (only one of which appears in Fig. 3,) which are mounted loosely on studs projecting radially from the shaft 14. Returning to the shaft A, another gear, 16, is fastened on it, which drives compound spur and beveled gear 17 18, loose on shaft 14, beveled gear 18 meshing with and driving gears 15. Loose on shaft 14, on the other side of gears 15, is another compound beveled and spur gear, 19 20, the beveled gear 19.meshing with and driven by gear 15, while the spur 20 meshes with and drives gear 21, fastened on the spindle-shaf t B. The motion of the spindle-shaft is thus the resultant of two motionsthe one invariable, transmitted from the shaft A directly to the beveled gear 18, the other variable, transmitted indirectly from the same source through the cone-drums, the variability of this latter motion being due to the shifting of the belt upon the cones.

Gis the rack-shaft by which the spindle-carrying rail 0 is raised or lowered,according to the direction of rotation of said shaft. The rail carries two or more vertical racks, which engage with corresponding pinions, C fastened on the rack-shaft. The reversinggearing for rotating this shaft alternately in one and the other direction is as follows: On shaft 14 is mounted a sleeve, 22, connected therewith by a spline-and-groove connection, so that while rotating with said shaft it may slide lengthwise thereon. On said sleeve are fastened two bevel-gears, 23 24, one or the other of which (according to the position of the sleeve) engages and drives a beveled gear, 25, fast on a vertical stud or shaft supported in a proper bearing, 26, and having on its lower end another beveled gear, 27. The latter gear drives beveled gear 28, which is loose on shaft 0, and fast to gear 28 is a long pinion, 29, which drives spur-gear 30, fastened on shaft 31. On shaft 31 is another gear, 32, which drives gear 33, fastened on rack-shaft G. Sleeve.

22 is moved so as to bring its gears 23 24 alternately in engagement with gear 25 by means of a shipper-fork, 34, whose arms straddle the sleeve and enter an annular groove therein in the usual way. The fork is attached to the upper end of the vertical rock bar or shaft 35, connected at its lower end by an arm, 36, to the longitudinallymovable reverse-shaft or shipping-rod D. This shaft D is moved alternately in opposite directions by the action of a grooved scroll-cam, 37, on rack-shaft O, in

end down between two washers, 42 43, loose' on the rod D. Between each washer and collars 44 and 45, fast on the rod D, are confined spiral springs 46 and 47, one or the other of said springs being compressed, according to the direction of movement of the shoe 39. A detent (which need not now be described) retains the rod in position while the spring is being compressed until at a predetermined time the detent is removed and the rod at once is free to move in the direction in which the expansion of the spring tends to force it. In the drawings, Fig. 3, the gear-23 engages gear 25, and the rackshaft G is thereby rotated in a direction to compress spring 46. The reverseshaft D, as soon as released, will thereby be forced to the left, thus throwing the gear 23 out of and the gear 24 into engagement with gear 25, thereby reversing the rotation of the rack shaft and causing the scroll-cam to move the shoe 39 in a direction to compress spring 47.

The rate of traverse of the spindle-rail 0 must of course be varied to conform the movement to different sizes of yarn. If, for instance, the movement be such as to lay the folds of coils of a given size side by side, the same movement would cause the coils of a larger size of yarn to overlap. In other words, the same rate of traverse which would answer for winding a threehank bobbin would not answer for winding a one, two, or four hank bobbin. To provide for this the gear 27 is made the change-gear-that is, this gear is interchangeable with others having a greater or less number of teeth, as requiredand the hub on which the compound pinion and beveled gear 28 29 is mounted to revolve is adj ustable longitudinally of shaft 0, so as to adapt the gear 28 to mesh with change-gear 27 ,whatever may be the variation in the size of the latter; and the pinion 29is made long,so as to permit it to partake of this movement of adjustment without being moved out of engagement with spur-wheel 30.

The foregoing general description of the machine is necessary to abetter understanding of my invention; but in the parts thus far described there is no substantial novelty, the spring-acting reverse-shaft or shipping-rod and parts immediately connected therewith being in substance like those described in Letters Patent No. 84,764, of December 8, 1868, while the devices for giving movement to the spindles and fliers are substantially similar to those that have heretofore been in use for like purposes.

I come now to those parts of the machine in which my improvements are moreparticularly to be found, and shall first describe the means by which a positive connection is es- ICC IIS

tablished between the cone-belt shipper-fork and the mechanism by which motion is imparted to the same.

In the present instance the belt-fork (shown at E in Fig. 2, and also in Fig. 6) is positively actuated from the shaft of the power'driven upper cone-drum, 4., as being the shaft most conveniently located for the purpose. Said fork has an internally-screw-threaded hub, which is mounted on the rotatable screwthreaded shaft 48 in such manner that the fork will be moved longitudinally of the shaft in one direction or the other, according to the direction of rotation of said shaft. The movement of the belt-fork is of course intermittent, and takes place at each movement of the reverse-shaft or shipping-rod D.

On the right-hand end of the screw-shaft 48 is a pinion, 49, gearing with an intermediate toothed wheel,50, which meshes with the spurwheel 51, whose hollow or tubular hub takes its bearing in a stand or bracket, 52. The intermediate 50 is journaled on a hanger, 53, steadied and held in place by encircling at its upper end the shaft 1-8 and at its lower end the tubular hub of the spur-wheel 51. On the hub of the spur-wheel is loosely mounted the oscillating pawl-lever 54, carrying a hinged pawl, 55, Fig. 11, which when the lever is moved in the proper direction engages and gives a movement of partial rotation to the spur-wheel 51, which movement through the gears 50 and 49 will turn the screw-shalt 48, and consequently move the belt-fork thereon.

The pawl-lever is actuated thus to move in the following way, referring more particularly to Figs. 12 to 1.8, inclusive: On the right-hand end of the shaft of the upper cone-drum, 4, Fig. 1, is a pinion, 56, which engages and continuously rotates (when the machine is in action) a spur-wheel, 57, which is fast on a tubular shaft, 58, supported in a suitable sleevebearing, 59, in the frame of the machine, which shaft on its opposite end carries a sprocketwheel, 60. Loose within the tubular shaft 58 is an arbor, 61, on which is fixed a disk, 62. This disk on its inner face, or face next to the wheel, carries in a dovetailed groove or way, 62, a slide, 63, slotted at its center, so as to straddle the shaft on which the disk is mounted, the slot being of sufficient-length to allow the needed range of movement to the, slide. From the inner lower portion of the face ofthe slide 63 projects a pin, 65, which extends inwardly past the sprocket-wheel into a camgroove, 66, formed in a tubular shell or case, 67, which is on the sleeve-bearing 59 and surrounds the sprocket-wheel. \Vhen the slide is in its lowest position, the pin is below the sprocket-Wheel, as seen in Fig. 12, and in this position the disk 62 is unaffected by the motion of the sprocket-wheel. \Vhen, however, the slide is raised far enough to engage the pin with the sprocket-wheel,the disk 62 manifestly will rotate with the latter, the arrangement being such that the disk will make one full revolution and will then stop by reason of the disengagement of the pin from the sprocketwheel, which is brought about by the shape of the cam-groove 66, into which the inner end of the pin projects.

The lifting of the slide at predetermined and appropriate times to throw the pin into engagcment with the sprocket-wheel is effected by a pivoted lever, 68, which by a rod, 69, is connected to the trip-lever 70, pivoted in a suitable stand, 71, and having its free end arranged to be acted on by a double incline, 72, on the reverse-shaft D. The lever normally stands in the position indicated in Fig. 12. When the reverse shaft D is thrown in one direction or the other by its actuatingspring, the incline 72 tilts the trip-lever, with the effect of raising the free end of the upper lever, 68, and consequently throwing the slide into engagement with the sprocketwheel. Having done this, the lever at once returns to the position shown in Fig. 12. Thus at each movement of the reverse-shaft the disk 62 will be caused to make one revolution, and said movement isavailed of to drive the pawl-lever 54. This is effected, as seen more plainly in Figs. 1, 11, and '12, byjointiug to the pawllever a eonuectingrod, 78, the upper end of which is hung upon a sleeve, 74, on a wrist or crank pin, 74:, on the outer face of the disk 62.

In winding bobbins of differentsized yarnsc. 9., one-hank bobbins, two-hank bobbins, &c.-it becomes necessary to vary the length of the intermittent movement of the belt-fork to correspond therewith. In winding a fine yarn,for instance, the intermittent movements of the belt-fork should be of less length than when winding a coarse yarn. One convenient way of making provision for this is to arrange the crank or wrist pin 74 so that it may be adjusted nearer to or farther from the center or axis of motion of the disk 62. The farther the crank-pin is removed from this point the greater will be the throw of the pawllcver, and consequently the greater will be the length ofthe intermittent movement of the belt-fork. To this end I in the present in stance form the crank-pin as a bolt, whose head 75 is contained in a radial undercut or flanged groove, 76, in the outer face of the disk 62, and 011 the outer screw-threaded end of said bolt, beyond the point where the connecting-rod 73 is mounted 011 the same, is a nut, 77, by loosening and tightening which the bolt can be free for purposes of adjustment, and can then be bound firmly in its adjusted position. In this way I actuate the belt-fork positively but intermittently by gearing, so as to insure most accurate and reliable action, which is a desideratnm in machinery of this character especially, and I am at the same time enabled to regulate and vary said movement of the belt-fork within all needed limits with entire precision and case.

It now remains for me to describe the means ICO ICS

IIC

by which the reverse-shaft is retained in position while one or the other of its springs is being compressed,and is then at predetermined times or intervals, which necessarily vary with the progress of the work of building up the bobbins, released,so that it may be free to move longitudinally the proper distance in the direction in which the spring so compressed tends to force it, and in the description of this portion of the machine reference may be had more particularly to Figs. 1 and 7 to 11, iiiclusive, of the drawings.

The view in Fig. 7 is taken looking at the parts from the side on which the shaft D (see Fig. 11) lies. The opposite side of the same is shown in Fig. 1.

The retaining ofthe reverse-shaft D in either one of the two positions to which it is moved by its actuating-springs 46 47 is effected by the angle or elbow lever F, hereinbefore termed by me the flap-lever. This lever is hung on a suitable vertical pivot, 66, on the base or lower part of the machine. One of the arms of this lever is forked, so as to straddle the shaft D and to extend between two collars, I), thereon. (The hub of the lever and a part of one of its arms are shown in Fig. 1.) The other and longer arm of the lever has on its upperface a rib, c, on which fits and is adapted to slide a wedge shaped or tapered detentblock, d, which is held in adjusted position thereon byaset-screw, e. Thelength of throw of the shaft D is invariable, so that the flaplever when at rest always occupies one of two positions, shown, respectively, in full and in dotted lines in Fig. 9.

' Mounted upon a suitable stationary bed, G, is the carrier H, which is held and adapted to slide longitudinally upon said bed. On the upper face of the carrier is a rack,f, which engages a pinion, h. This pinion is fixed on a shaft mounted in a proper bearing on the frame of the machine, and having at its other end a beveled gear, t, which meshes with a like gear,

5 j, on the rack-shaft O, which raises and lowers the spindles. In this way the slide is actuated to move back and forth on its bed, following the reversals of movement of shaft 0.

Upon the front side of the sliding carrier H is mounted in suitable bearings a rotatable right-and-left screw-shaft, I, one end of which extends through the tubular hub of the spurwheel 51, and is connected thereto by a longitudinal spline-and-groove connection, so that while it in following the reciprocating movement of carrier H may move back and forth in the tubular hub it at the same time will partake of the intermittent rotary movement of the latter, due to the action of the pawl-lever 54. Upon the front side of the carrier H are two dogs, is, which may be called the detentdogs, held and adapted to slide on the said carrier and mounted on the shaft I-one on the right screw and one on the left screw of said shaft, so that said dogs will be caused to approach or rccede from one another, according to the direction in which the shaft is rotated. The lower ends of these dogs extend down far enough, as seen more plainly in Fig. 11, to come opposite the inclined side faces of the detentblock d, and the inclination of these side faces is such and the parts are generally so arranged and placed that one or the other of said inclined faces will be brought into parallelism with the depending ends of the detent-dogs, and that said dogs will in following the reciprocating movement of the carrier travel along and in contact with one or the other of said faces. The range of the movement of the carrier is such that at either extreme of its movement the dogs will be carried beyond the block (I, and according to the distance which separates the dogs they will contact with and control for a corresponding longer or shorter period the detent-block, and consequently the flap-lever.

This being the organization of parts, the operation is as follows, the parts being appropriately positioned and timed for the purpose: The detent-dogs at the outset are preliminarily set apart the greatest distance required for the work, this being accomplished by lifting the pawl 55 out of engagement with the wheel 51 and then turning the latter by hand in the requisite direction and to the requisite extent, with the effect also of properly setting at the same time the shipper-fork of the cone-drums. The operation last named, however, can be performed independently by removing or unkeying temporarily the intermediate 50 and then rotating the shaft 48 by hand. When the machine starts, the spindle-rail, actuated from the shaft 0, moves the proper distance upwardly. During this time the appropriate spring on the reverse-shaft D is being compressed, but the rod itself is held immovable by the detent-dogs, which bear against the detentblock, and thus lock the flap-lever in position against the stress of the compressed spring. This continues until the dogs clear or pass beyond the detentblock. As soon as this takes place,the reverse-shaft D isimmediately moved longitudinally by its compressed spring. In its movement it throws the pawl-lever, adjusts the belt-fork, and, through the shipping-lever 34 35, reverses the rotation of shaft 0. At the same time the rotation of the spur-wheel 51, due to the action of the pawl-lever, has rotated the right-and-left screw-shaft I in a direction to bring the dogs nearer together, the extent of this movement of the dogs being commensurate with and determined by the throw of the pawl-lever, and thus perfect correspondence between the adjustments of the belt-fork and the detent-dogs is secured, both being governed by and dependent upon the same comm on instrumentality-to wit, the pawl-leveror, in other words, the spur-wheel 51, actuated by said lever. By said movement of the reverse-shaft the flap-lever has also been brought to appropriate position for the other inclined face of its detent-block to meet and co-operate with the detent-dogs during the return movement of the carrier. The same series of operation now takes place in the opposite direction, and so on, the detent-dogs at each movement of the reverse-shaft being caused to approach one another, so as to gradually shorten the intervals between said movements. In this way I obtain a positive and sure lock for the reverse-shaft during the time in which it should be held immovable, and at the expiration of that time effect the certain and instantaneous release of said shaft. By the use of detent-dogs adjusted in the manner indicated I am enabled to regulate and vary with the utmost nicety and precision the throw of the reverse-shaft to accord with the varying'conditions which obtain during the operation of building up the bobbins.

With respect to the shipper-fork for the cone-belt and its actuating-gearing, I remark that the sprocket-wheel and slide-pin virtually constitute a clutch by which said gearing, intermittently at stated times and for definite periods only, is connected to the shaft by which said gearing is driven during said periods. The form of clutch shown is that which, on the whole, I deem to be most convenient and best adapted for the purpose. Obviously, however, other forms of clutch might be substituted for the one shown without departure from my invention. So, also, the construction and arrangement of the detent mechanism for the reverse-shaft, the pawl-lever and its adjustment, &c., can vary considerably without essentially departing from the principle of my invention. I therefore do not restrict myself to the particular details hereinbefore shown and described; but,

Having described my improvements and the best way at present known to me of carrying the same into practical effect, what I claim herein as new and of my own invention is- 1. The pivoted pawl-lever and devices for oscillating the same, in combination with the gearing operated by said pawl-lever, the conebelt shipper-fork connected to and actuated by said gearing,thcdriving-shaft, and clutch mechanism whereby the pawl-lever-actuating devices are intermittently caused to engage said driving-shaft at the times and in the manner substantially as hereinbefore set forth.

2. The pivoted pawl-lever and means for varying and adjusting the throw of the same, in combination with the gearing operated by said pawl-lever, the shipper-fork connected to and moved by said gearing, the driving-shaft, the pawl-lever-actuating devices, and clutch mechanism whereby the said pawl-lever-actuating devices are caused to intermittently engage said driving-shaft at the times and in the manner substantially as hereinbefore set forth.

3. The combination of the intermittently-reciprocating reVerseshaft, the power-driven continuously-rotating sprocket-wheel, the disk provided with a slide pin to engage said sprocket-wheel, and thetrip-lever system actuated from said reverse-shaft to raise said slidepin into engagement with the sprocket-wheel at the times and in the manner substantially as hereinbefore set forth.

4. The spring-operated reverse-shaft, the flap-lever, and the detent-block mounted on and carried by said lever, in combination with the detent-dogs and the reciprocating carrier, whereby said dogs are brought alte'rnatelyinto and out of engagement with said detent-block, substantially as and for the purposes hereinbefore set forth.

5. The reciprocatory carrier, the detent-dogs adj ustably mounted thereon, and mechanism, substantially as described, whereby at each traverse of the carrier said dogs are brought nearer together, in combination with the spring-operated reverse-shaft, the flap-lever, and the detent-block on said lever, substantially as and for the purposes hereinbel'ore set forth.

6. The combination, with the flap-lever, its detent-block,and the springoperated reverseshaft, of the reciprocating carrier, the rightand-left screw-shaft carried by the same, the detent-dogs mounted on said shaft,and mechanism whereby at each traverse of the carrier said shaft is rotated in a directionto cause the said dogs to approach each other, substantially as and for the purposes hereinbefore set forth.

.7. The combination, with the intermittentlyoperated gearing by which the conebelt shipper-fork is actuated, of the reciprocating dogcarrier, the detent-dogs,and the right-and-left screw-shaft on which the dogs are mounted, said shaft being supported by and moving with the carrier, and having an extended end which enters and is adapted to slide back and forth in the hub of one of the wheels of said gearing, and is connected therewith by a longitudinal spline-and groove connection, substantially as and for the purposes hereinbef ore set forth.

8. The combination of the cone-drums, the cone-drum belt, the shipper-fork therefor, the intermittently-moving gearing by which said fork is positively actuated, the spring-operated reverse-shaft, the flap-lever and its detentblock, the reciprocatory dog-carrier, the dctent-dogs, and the right-and-left screw-shaft on which said dogs are mounted, these elements being arranged and connected together for joint operation and timed in their movements relatively to one another, substantially in the manner and for the purposes hereinbefore set forth.

In testimony whereof I havehereunto set my hand this 24th day of December, 1885.
