IMPROVEMENT IN SELF-ACTINGl JACKS FOR SPINNING.

Specification forming part of Letters Patent No. 94,278, dated August 31A, 1869; reissue No. 4,688, dated January To allpersons to whom thesepresents may come Be it known that I, WILLIAM H. BROTHERS, late of Winooski, in the county of Chittenden and State of Vermont, have made a new and useful invention having reference to the machine used for spinning, and commonly called a J ack 5 and do hereby declare the same to be fully described in the following specication and represented in the accompanying drawing, of Which- Figure 1 represents a plan or top view of a jack provided with my invention. Fig. 2 is a vertical section of the same, the plane of section being taken on the line a; a' of Fig. 1. Fig. 3 is a rear elevation in part, some portions of the mechanism being exhibited in section, the line of section being' shown at z z in Fig. 4. Fig. 4 is a vertical section taken on the line g/ y, Fig. 3. Fig. 5 is another vertical section taken on the line z z, Fig. 4. f

In these several gures like letters of reference indicate the same parts.

The object of the invention is to render the jack automatic in its operations.

I have combined with the jack, or its principal characteristics, peculiar mechanisms for the followingrpurposes: For stopping the rearward motion of the carriage in order that it may stand still long enough for the yarns to receive the proper amount of twist; for effect ing the forward movement of the carriage; for causing, during the advance of the carriage, the rotary motions of the spindles necessary to eifect the winding of the yarns on the bobbins of such spindles.

In the drawing A denotes the frame of my improved or new spinning-machine. B is a driving-shaft, employed for transmitting motion to the machine, the rotary motion of such shaft being imparted to it from a suitable C is the carriage, whose Wheels a a rest on guide-rails b b, arranged, in the ordinary manner on or making part of the frame A. The said carriage is to be of the usual construction and to have the spindles applied to it in the ordinary manner, and is to be provided with the usual squaring-bands d d and the grooved Wheels c for such bauds to run on. The faller is shown at D, it being pivoted or applied in `the usual manner to the carriage.

The arms e e of the faller are shown as projecting from a shaft, f, Whose journals are supported by legs or standards g projecting from the carriage. A Weight, h, fixed on an arm projecting' rearward from the shaft f, serves to overbalance the faller and hold it in its high.

carriage (l is, by means of'two scroll-bands, H

H and I I, connected with the driving mechanism. One end of each of the said bands is fastened to the carriage, the bands being' carried around grooved wheels @c fr, arranged at the rear of the frame A, or in standards erected on the iioor. These bands are also applied and fastened to scroll-pulleys y z, arranged as shown. The bands H H, going about the 'scroll-pulley y, serve to eifect the retreat of the carriage, the bands I I going about the scroll-pulley z serving to produce its advance or its movement toward the roving-spools. The pulley y is mounted on a shaft, J, provided with a gear, al. The pulleyz is lXed on a horizontal shaft, L, which carries and is driven byfa toothed wheel, b1, that will be thrown into engagement with the clutch c1 when the shaft L is set in motion. The main driving-shaft carries a loose drum, composed of pulleys d1 e1, which, by means of a hand-shipper, lVI, may be moved endwise on the shaft B so as to eifect the engagement of the drum with or its disengagement from the lshaft through the means of a clutch, f1, one portion of which is lixed'to the shaft and the other to the drum. When the drum is in engagement with the shaft B it will be revolved by it, and will thereby be caused to impart motion to the endless belts g1 .jl going around them. The belt glpasses over one of two pulleys, h1 il, arranged on a horizontal shaft, N, which is arranged, as shown, in the lower part ofthe frame A, the pulley h1 being xed on the said shaft N, and the pulley il being so applied to the shaft as to turn freely upon it. The belt )'1 is A that l N. (See Figs. 2 and 3.)

tted over a pulley which is mounted on a horizontal shaft, O, arranged, as shown, in the frame A. A pinion, m1, fixed on the shaft 0, is constantly in gear with the loose toothed. wheel b1, and when in movement revolves the same, so as to impart rotary motion to it and its shaft L, provided such shaft, by means of the clutch c1, be engaged with the wheel` bl. The shaft B, being turned in the direction of the arrow l, will revolve the shaft O in the same direction, and will also revolve the shaft L, so as to cause the scrollpulley z to be turned in the direction indicated by the arrow 2,the carriage being advanced toward the spools while the scroll-.pulley is so moved. When the belt gi1 is on the fast pulley h1 the shaft N will be revolved in the direction of the arrow 5 and will impart motion in the same direction to the shaft J, which, through intermediate gearing, as hereinafter described, will revolve the scrollpulley y, in order to cause the carriage to retreat or move backward to draw out the rovings. A short arbor, n1, has its bearings in a slide-plate, 01, shown particularly in Fig. 5, said plate being disposed on the rear side of art of the frame in which the various shafts B J L N 0, hereinbefore referred to, are

arranged. The arbor nl carries two pinions, p1

q1, that gear respectively with toothed wheels al r1, the latter of which is fixed on the shaft The wheel al, as before mentioned, is fixed on the shaft J of the scroll-pulley y., When the plate o1 is lowered into the position as shown in Fig. 2, it will cause the gears a1 and r1 to be engaged through the intervention of the gears p1 q1, whereby, whenever the belt g1 is on the fast pulley h1, motion will be transmitted from the shaft N to the scroll-pulley y, which, being thus revolved, will cause the carriage to retreat or be moved in the direction of' the arrow 3. (See Fig. 2.) The said movement of the carriage will be arrested whenever the stop s1 projecting down from the carriage, as shown in Fig. 2, is carried into contact with a lug, t1, so as to move a slide-bar, P, from which such lug projects. The said bar P at its front end is pivoted to the lower arm of a lever, u1, whose fulcrum is supported by a stationary arm, el. At its upper end the lever carries a friction-roller,'w1, extended underneath a lug, x1, projecting from the slide-plate o1. When, during the retreat of the carriage, the stop S1 is carried against the lug t1 and thereby moves the bar P rearward, the lever u1 will be moved into a vertical po sition, thereby carrying its roller under and against the cam or lug x1, and, as a consequence, elevating it and the plate 01, so as to raise the wheels 191 q1 out of engagement with the gears al r1, which taking place, the rotary motion of the scroll-pulley y will be arrested thereby, causing stoppage of the carriage. The carriage after this has to remain stationary a sufficient period to allow of the requisite twisting of the yarns, which is carried on by means of an endless belt, R, which passes around a pulley, zl, fixed on the shaft N, and thence j slot, through which the belt g1 runs.

around a guide-pulley, a2; thence around a pulley, yl, fixed on the shaft E of the carriage; thence around other guide-rollers, a2 a2, and forward to the wheel Z1, all being as shown in Fig. 2.

During the retreat of the carriage, and just before the termination thereof', a roller, r, at the end of an arm, q, carried by the carriage, meets and rolls upon a curved arm, b2, of a bell-crank, S, pivoted to the rear part of the frame A or to the floor. A rod, T, pivoted to the wrist of such crank, extends forward through an arm, c2, projecting from a vertical shaft, U, arranged as shown in Figs. 1 and 4. On the rod T are three shoulders or fixed collars, d2 e2 f2, arranged as shown in Figs.2 and 4, a helical spring,` g2, being on the rod, and resting against the arm c2 and the shoulder e2, as shown, the spring tending to push the arm backward. The rod T, when next the shoulder f2, goes through an arm, h2, projecting from a vertical rock-shaft, V, arranged as shown in Figs. 1,2, 3, and 4. This vertical rock-shaft V carries or rather is connected with the clutch-lever W, by which the loose wheel b1 is thrown into or out of' engagement with the clutch-shaft. Two otherarms, i2 jz, extend from the rock-shaft U. The upper one, jz, straddles a horizontal slide-rod, X, while the lower one, 2, is connected with a toothed wheel, Y, that is arranged on and so as to slide upon the shaft N. (See Fig. 3.) Whenever the roller pr' of the carriage meets and rolls upon the arm b2 of the bell-crank S, the rod T will be retracted, thereby causing, by means of the spring g2, the shaft U to be turned, so as to carry the slide-rod X and the wheel Y toward the scroll-pulley z. The slide-rod X has a Whenever, by the aforesaid action of the rod T, the slide-rod X is moved in the direction of the arrow 4, (see Fig. 5,)it will carry the belt g1 from the fast pulley h1 to the loose pulley il, in consequence of which the shaft N will cease to be revolved by such belt. At the same time the conic frustum of the wheel Y will be moved up into the conical space in the adjacent wheel zl, fixed on the shaft N, the two constituting a frictiouclutch. The wheel Y will also be thrown into engagement with a loose pinion, l2, on the shaft L. The pinion l2, by an intermediate gear, mz, engages with a pinion, a2, fixed on the shaft O. The wheel Yv is thus thrown into gear with the shaft O, which is constantly revolved by the belt jl, and imparts the regular motion in the direction of the arrow 5 to the shaft N, the said motion being only much slower than that imparted to the sha-ft by the belt g1. The hollow friction-Wheel al drives the endless belt R, which imparts motion to the shaft- E, as before described, such movementof the belt R by the wheel Z1 being for reversing the motion of the shaft E, in order to effect what is termed the backing off ofl the yarn on the spindles. During all the period that the carriage is retract-A ed and stationary the wheel b1 is unclutched of such plate.

\ to allow the plate B1 to fall.

from its shaft L of the scroll-pulley z. When the slide plate owas elevated, as aforesaid, it, to insure the stationary position of the scrollpulley y, was automatically locked in its position by a swinging hook, Z4, pivoted to the frame A, such hook at the time enteringa notch (See Fig. 5.)

In recapitulation, it may be stated that the shaft N, when driven by the belt g1, caused the carriage to retreat and the belt R to be turned, but as soon as the carriage reached its rearmost position the motion of the shaft N was taken bythe shaft O so as to become slower, the carriage being stopped a sufficient period for the necessary twisting of the yarns to be produced. The belt g1 was slipped upon the loose pulley, but still the shaft N continued to rerevolve by being connected by the clutch Yzl and intermediate gears, as described, with the shaft O, the latter shaft not being in gear with the shaft L during the retreat and stoppage or interval of rest of the carriage. By means of the belt 02 (see Figs. l, 2, and 3) and pulleys on the shafts N and A1, the latter will be revolved, such shaft Al being situated as represented. It has xed to it a worm, p2, to engage at certain times with a Wormgear, q2, supported on an arbor projecting' from the slideplate B1. (See Figs. 3 and 5.) Vhen the plate B1 is elevated it will be locked by a sliding spring-catch, r2, (see Figs. l and 5,) which then takes into a notch, u2, of the plate B1, and has a projecting arm, s2, as shown. From the wheel q2 a finger or stud, t2, projects, as shown, it, during each revolution of the wheel, being carried into contact with the arm s2, so as to push the catch r2 out of the notch u2 in order By means of lever (11(see Figs. 3 and 5,) the slide-bar Bl is connected with the shipper-rod X in such manner that the latter will be moved in the direction of the arrow/1.(see Fig. 5) while the plate B1 is being` lowered, and'it will be moved in the opposite direction while the said plate is in the act of being elevated. While the carriageV C is retreating and at rest, as aforesaid, the plate B1 is held elevated by the catch 12, and

'the shaft A1 is therefore in engagement with the wheel q2. As soon as the linger t2 of the wheel q? strikes the arm s2 of the catch the plate B l will be released and will descend by its own weight, and thereby cause the shaft or rod X to 'be moved in the direction of the arrow 4. By this further motion of the bar X the clutch-lever W will be so moved as to carry the pinion b1 into engagement with the clutch c1 and the pinion m1 ofthe shaft O. The scrollpulley z 'will then be operated by the revolution of its shaft L so as to effect the advance ofthe carriage. When the roller i' ofthe carriage C leaves the arm b2 the spring g2 will be free to act to draw the rod Tforward, and will do so, and at the same time will cause the friction-wheel Y to be moved out of contact with its fellow wheel 21, thus leaving the carriage free for its further advance toward the roving'- rollers. On nearly reaching the terminus of its advance a friction-roller, wz, supported by a projection, e2, from the carriage, will be pressed under and against the inclined arm 3:2 projecting from the plate B1, and will thereby move the slide Bl so as to cause the rod X to be moved back, whereby the shaft L will be unclutched from the Wheel bl, and the belt g1 will be thrown or moved upon the fast pulley h1. At the same time another lug, y2, from the carriage, by acting againstan arm, z2, projectin g from the hook 24, throws such hook out of the notch in the plate o1 and allows the latter to drop. Thus, by unclutching the wheel b1 from the rod or shaft X, the scroll-pulley z will be arrested in yits motion andthe advance of the carriage will accordingly be arrested, while at the same time, by the belt g1 being moved upon the fast pulley and the plate o1 being dropped, the scroll -pulley y will be thrown into action so as to cause the carriage to retreat for the purpose of drawing ont the yarns. As the plate B1 is elevated its wheel g2 will be moved into engagement with the wormpz. When the wheel q2 may have turned sufficiently, its pin t2, by being moved against the part s2 of the slide r2, will operate such slide so as to force it out of the notch a2, thereby setting free the slide-plate B1, which will then drop. .The carriage is thus moved automatically. After the backing-off"7 operation has taken place, and before the spindles commence to wind up the yarns, the faller D should be lowered, which is effected by the winding of the strap j upon the loose pulley K. weight h, while the strapis being unwound from the said pulley, will gradually raise the faller and restore it to its normal position. As the carriage may approach the termination of its advance the arms l Z of the counter-faller Will pass under and against a cross-bar, a3, of the frame, whereby the said counter-faller wire will be depressed and the arms l t will be engaged with the arms n u of the rod f. While the counter-faller by such arms is held depressed, so as to be out ofthe way, the faller, for the same reason, will be held up until drawn down by the strap j. The shaft E carries a pulley, e3, (see Fig. 1,) about which and a pulley, 03, (see Figs. l and 2,) a crossed band, b3, is arranged. The band d3 winds about a barrel of the said pulley o3, and at one end is fastened to a spring, as shown in Fig. l, the other end of the band being secured to the nut of the quadrant-screw at the rear part of the frame. The pulley e3 runs loosely on the shaft.

E, and such shaft and pulley have a ratchet and pawl, by which the pulley, when moved one way, turns the shaft, but revolves freely on it while being moved in the opposite direction. The shaft E by such means is revolved while the carriage is runningin oradvancing, the object of so revolving the shaft being to effect the winding of the yarns on the bobbins. Stops, as shown at f3 in Fig. 1, are to be arranged in the frame to arrest the advance of the carriage, so as to prevent it from contact with the driving machinery.
