JOHN GOOD, OF FAR ROCKWAY, NEW YORK.

SPINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 541,271, dated J' une 18, 1895.

Application filed September 27, 1894. Serial No. 524,223. (No model.)

To all whom, it may concern.E

Be it known that I, JOHN GoD,of Far Rockaway, in the county of Queens and State of New York, have invented a new and useful Improvement in Spinning-Machines, of which the following is a specification.

This invention relates more particularly to a spinning machine of the kind known as the jenny used for the spinning of twine and of yarns for cordage, and the object of the improvement is to simplify the machine and to enable it to be driven at a higher speed than has hitherto been practicable.

The nature of the improvement will be described with reference to the accompanying drawings and its novelty will be set forth inl the claims.

Figures l and l* represent together a side elevation, partly in section, of a machine embodying my invention; Fig. 2, an elevation of the driving end ofthe machine; Fig. 3, a transverse vertical section in the line 3 8 of Fig. l; Fig. 4, a transverse vertical section in the line 4 4 of Fig. l; Fig. 5, a central longitudinal sec tional View of the bobbin and flier and their immediate appurtenances; Fig. 6, a central longitudinal sectional view of the friction device which produces the draft on the yarn or twine between the bobbin and the flier. Figs. 7 and 8 are `detailviews which will be hereinafter explained. Fig. 9 represents a transverse vertical section'of the machine in the line 9 9 of Fig. 1*.

Similar letters and figures of reference designate corresponding parts in the several tignres.

A is the framing of the machine.

B is the main shaft arranged at one end of the framing transversely thereto and lfurnished with fast and loose pulleys C C which receive motion through the main beltD which is shipped from one of said pulleys vto the other by a belt-shipper D. v

E is a horizontal shaft running lengthwise of the machine and deriving motion from the main shaft B through bevel gears a b. This shaft E carries a pulley F for driving the iier N N', a pulley G for driving the bobbin P and an endless screw H for driving the chains I which carry the gill-pins c c; the said endless screw H gearing with and drivinga worm-gear J on a transversely arranged shaft K which carries a pulleyL from which a belt L runs to and drives a pulley M on the driving shaft d' of the gill-pin chains I.

The flier N N herein represented consists of a cylinder open at one end and closed at the other end by which it is attached to its journal e which runs in two journal boxes e on the top of the framing and is furnished with a pulley e2 to receive the driving belt F from the pulley F. This cylindrical flier is represented as composed of a metal disk N and cylindrical shell N attached at one end to said disk. This cylindrical shell I make of a piece of seamless paper tubing because that material is very cheap and enables a flier having the necessary stiiness and strength' to resist the elects of centrifugal force to be made of less weight than a metal flier of cylindrical form and therefore to be run at a higher speed and with less wear of jour` nals and tobe more'easily stopped when run at a high velocity. The metal disk N is represented (see Fig. as-formed with a rim projecting from its face substantially parallel with Vits axis for the purpose of attaching the shell N which fits tightly over the said rim and is attached thereto in any suitable and secure manner as by screws f. The hier thus constructed is furnished internally with sheaves g, 71, t' for guiding the yarn from its eye j to the bobbin. The sheavesi which are arranged near the mouth of the flier and are attached to the shell N of paper or light material, are pivoted in metal angle pieces t" which are riveted or securedA to the shell as indicated at i2 in Fig. 3. The journal e of this hier may have a capstan head e3 of any known or suitable kind. 5

The bobbin P is represented as carried and driven in a well known manner by a central supporting spindle la and a hollow driving spindle Z, through which said spindle k passes freely, the said spindle Z being furnished with the pulley lo' receiving Athe driving belt G from the pulley G. The driving spindle Z runs in bearings 7a2 in a carriage P which is fitted to slide in a direction lengthwise of the spindle in ways k3 on the top of the framing. lVhen in operation the supporting spindle k is supported at itsinner end, as shown 'at m in Fig. 5,in a bearing in the inner end of the flier journal, but it is always supported both I 1 hanger p' secured to the sliding carriage P',

in the hollow driving spindle l and in a fixed bearing in a small stand n on the top of the framing. This stand fn is fitted as shown in Figs. l and 2, with a vertically sliding bolt 'n' which abuts against the outer end of the spindle lr, when the said spindle is in its operative position and so locks it. This arrangement of the supporting spindle k and the means of locking it endwise are not new and are only here described as leading to the further explanation which will be hereinafter made of the means of simultaneously locking the said spindle andthe traverse screw Q and y simultaneously unlockingthem.

The traverse screw Q turns in a box p in a the said box containing the usual switch nut for workingl eitherin the right hand or in the lefthand thread of the said screw. The shaft of said screw also fits in bearings in two sta- 'tionary hangers p2 p3 dependent from the framing A, and it is capableof sliding lengthwise outward through and beyond `the said bearing in p2. The said shaft is furnished with a bevel gear p4 which gears Awith a bevel gear q on the upper end of an upright shaft q, which turns in a bearing in the bottom of the hanger psand a second bearingg5 secured.

to one of the journal-boxes of the shaft K, the said-shaft being furnished on its lower part with va bevel gear q2 which gears with a bevel gear g3 on the transverse shaft K hereinbefore described, the said bevel.v gear g3, shaft q and bevel gears q and p4, thus driving the traverse screw. lheltra'verse screw when in operation is confined longitudinally between Y its bearings in the hanger p3 and a downward projection fr on a hand-lever R (see Figs. l and 2) which works on a fixed fulcrum'fr in the end of the framing outside the hanger p2. A laterally projecting arm of this y lever is connected as shown in Fig.V 2, by a slot and pin connection 'r2 with the fsliding bolt n which locks the bobbn supporting spindle k in place. In the normal position to which this lever is brought by the weight of its laterally projectingV arm and of the sliding bolt n', the said bolt abuts against Yand acts as a stop to lock the spindle 7c and at the same time the projection fr on the hand-lever forms an abutment anda stop to the outer end of the traverse screw and both the said spindle and the screw are locked endwise while the machine is in operation and until it is desired to remove the bobbin when .the hand-lever is brought lo a position to uncover the outer ends ofthe said spindle and screw and allow both the said spindle and screw to be drawn outward, the drawing outward of the screw being necessary to permit the drawing back of the carriage P and spindle Z to draw the bobbin out ot' the flier, because the screw is always engaged with the said carriage bythe switch nut in the box p.

S (Figs. l and 6) is the friction disk for producing the draft on the yarn between the flier and the bobbin. This friction disk is applied on the shaft E and operates against one side of the bobbin driving pulley G.

The said disk is formed upon or rigidly se-` thereon but it is held against the friction disk S in such manner as to be capable of being turned by the friction thereof by means of acoil-spring t which surrounds the sleeve S wherever lit is incased by a. box S2 and 'held abutting against the said spring by nets t fitted to a screw thread on the sleeve. screwing up these nuts the spring tis adjusted to exert a greater or less Vpressure against the pulley and so toV adjust the friction which the'said pulley receives from the disk S and thereby adjust the draft on the yarn as t-he flier is driven positively by the pulley F on the shaft E, While the bobbin is driven by the frictiouof the said disk S. The sleeve S is .jonrnaled, as shown at s2 in Fig. 6, into a rigid hanger P2 dependent froln the "bobbi'n carriage P', in such manner that the said sleeve may turn freely in said hanger but is compelled by it to move with the said` carriage in the traverse movement of the bobbin and so to carry thepnlley G and the'triction disk back and forth along the shaft E and keep the pulley G and belt G always in proper relation `to the bobbin pulley k.

The condenser T represented kin Fig. 1 may vbe of any known or suitable 'kind and therefore needsno particular description.

The machine is fitted with a stop motion IOC which provides for stopping it automatically and almost instantaneously under the followingcircumstances, viz: first, in case of interruption of the supply of sliver toY thecha'ins of gill-pins; second, in case ofthe yarn or twine breaking or being interrupted between the vflier and the condenser orgill'pi'ns; third,`

The stop shaft U which Vextends as shown in Fig. l, from the driving end of tliemachine to a little beyond the head of the flier is fur nished with a hand-lever U (Figs. l and 4) which may be termed the stop lever. The said shaft is also furnished with an arm u' (Figs. l and 2) connected with and operating the belt-*shipper D', andis'iurther furnished with an arm u2 (Figs. l and 3) for throwing and holding off the brake F2 from the flier driving pulley F, and with a cam u8 (Figs. 1,

2 and 7) forthrowing and holding of the brake rod a4 connected with it, another arm carry-- ing the brake shoe @t5 which acts on the inside of the rim of the pulley F, and the third arm being connected with the framing A by the spring u@ which always tends to p ut the brake in operation and at the same time act-- ing through the brake lever, the rod n4 and the arm u2 of the stop shaft U, always tends to turn the said shaft in a direction to make its arm u' ship the main belt from the fast pulley C to the loose pulley C. This action of the said spring is counteracted, when'the machine is in proper operation, by means of a small lever W which I call the locking lever, which is furnished with a hook w which hooks over a projection w on the hand lever and so holds the said lever in a position to keep the brake F2 out of operation and to hold the belt-shipper in position to keep the belt on the fast pulley.

The brake Gr2 of the bobbin driving pulley G which is shown in Fig. 2 buty more clearly in the separate view Fig. 7, has to move with the said pulley along the shaft E and therefore it is attached to the bobbin-carriage.

The said brake G2 consists of a lever, the fulcrum 13 of which is affixed to the'hanger P2, one arm of the said lever constituting the brake shoe and operating on the outer periphery of the said pulley and the other arm being connected with the said hanger by a spring yu which exerts a constant tendency to apply the brake to the pulley but the action of which, when the machineis in proper operation, is counteracted by the cam us before mentioned on the stop shaft U. This cam must be of a length in the direction of the length of the stop shaft, as shown in Fig. 1, a little greater than the length of the bobbin traverse in order that it may remain operative in all positions of the bobbin.

The tripping shaft V which extends (as shown in Figs. 1 and 1*) from a position in rear'of the chains I to a position some distance beyond the frontend of the flier, is furnished with an arm v2 (Figs. 1 and 9), a hooklike cam v3 (Figs. 1 and 4), which may be termed the tripping caml and with an eccentric-like arm o4 (Figs. 1 and 3). vThe arm U2 whiehvis at the rear end of the tripping shaft has a crank-pin 14 which is received in alink or fork 15 on the lower end of a rod 16 which is suspended from one of two levers 17 in which is journalerl the upper one of the feed 4 rollers 18,18%' for feeding the'sliver to the chains l of the gill-pins c, the said levers having affixed fulerum 19 and being so proportioned that a very slight upward and downward movement of the feed roller 18* produces a very considerable rise and fall of the rod 16. While there is a proper supply of sliver to the feed rollers 18, 18* the rod 16 is so held up that its link orrfork leaves the wrist-pin 14 of the arm U2 of the tripping shaft free and the tripping shaft is held against any tendency to turn accidentally in the direction of the arrow shown near it in Fig. 4, by the engagement of its tripping cam 'v3 with a small projection 20, preferably con-l sisting of a friction roller, on the hooked locking lever )V which is then itself 'locked by the engagement of its hook w with the projection w on the hand-lever U; but when the supply of sliver to the rollers 18, 18* isinterrupted, the roller 18* comes down so low that by its action through the levers 17 andithe rod 16, the upper end of 'the link 15 ofth'e said rod will bear down on the arm 'v2 of the tripping shaft V andthe said shaft will thereby be caused to turn in the direction of the arrow shown neaf'lit in Fig.4. The tripping cam U3 then, by its action against the projec-Y tion or roller 20 on the locking lever lV, will lift or trip the said lever clear of the pr0jection w on the stoplever V', and so liberate the stop lever and leave the stop shaft free to the action of the spring u by which the main belt D is shipped to the loose pulley andthe brakes are brought into operation to stop the flier and the bobbin almost instantaneously. It will be understood that as the traverse screw and the gill-.pin chains are driven from the same shaft F as the flier and bobbin, all will be stopped together and at the same time the feed rollers 18, 18* will be stopped as these rollersare driven by a belt 21 running to a pulley 22 on the roller 18 from a pulley 23 on the chainY shaft 24.

For the purpose of causing the stoppage of the machine by a disengagement of the lockingV lever W from the stop lever U, similar to that above described, Whenever the yarn or twine is broken or interrupted between the `filer head and .the condenser or the gill-pin chains, the locking lever is furnished with an upward prolongation 25 toward the iiierhead e3, as shown in' Fig. 4, and there is provided in the flier head opposite this prolongatioma centrifugal tripping tappet Y consisting of a short pin which is fitted loosely within and projects through a hole or mortise bored or cut transversely through the flier head. ln this tappet there is a hole 28large enough for the yarn or twine 4to pass freely through. One of the projecting ends ofthe said tappet is represented as provided with a head 2G and the other as having a pin 27 inserted through -it to prevent it from coming altogether out of the hier head, and one endfor instance that which has the head, is made heavier than the other-so that when the flier is in motion the centrifugal force developed in the Said tappet will tend tomake the tappet fly out in onedirection from the -fiier head, .bntwhile there is any yarn or thread ICO lIO

passing through the hole .in the tappetfthat will counteract this tendency. When, however, the yarn or twine is broken or interrupted there will be no restraint to the centrifugal tendency and the tappet will instantly fly out far enough to strike the prolongation 25 of the locking lever W and so to throw the said lookin g lever out of engagement with the stop lever U and leave the stop shaft free to the action of the spring 'a6 which produces the stoppage of the machine as before'eX- plained.

The eccentric-like arm 'U4 (Fig. 3) on the tripping shaft V is for the purpose of stopping the machine when the proper quantity of yarn or 'twine has been spun on to the bobbin'P. This arm c4 is situated near the mouth or open end of .the flier and in such position (see Fig. 3) that when the tripping shaft is in position for the proper operation of the machine, the heads of the bobbin may pass clear of the said arm to permit the bobbin to pass into the flier. When a body of yarn on the bobbin arrives at a certain circumference, its outer coils will come against and so press down the said arm and turn the tripping shaft V as to produce the action of the tripping cam v3 on the locking lever. as hereinbefore described for disengaging the stop lever and causing the stoppage of the machine. It may be here mentioned that the arm v4 is not necessarily of eccentric-like form but is merely made round to prevent any loose portions or fibers of the yarn from catching on it.

After the machine has been automatically stopped in any of the ways hereinabove described or after it has been stopped under any circumstances and when it has -been again started by pulling outward the stop lever U by hand and thereby shipping the belt D on to the fast pulley C and throwing ont' the brake F2, the locking lever W is operated by hand to re-engage with the projection w on the stop lever and lock the latter lever. By this re-engaging movement of the locking lever the projection 2O on the said lever is made to so act upon the tripping cam u3 as to turn the tripping shaft into the position in which it is ready to trip the locking lever W by the filling up of the bobbin or bythe interruption of the sliver between the feed rollers 18, i8* in which position also thecam a3 on the said shaft also holds the spindle pulley brake Gr2 out of operation. the locking lever brings its upper arm 25 into position to be operated by the action of the centrifugal flier tappet as hereinbefore described.
