IMPROVEMENT itl` Looms.

Specification forming part of Letters Patent No.1r36,133, dated February 25, 1873.

- ing fancy goods, or to the combination and arrangement in such looms ofmechanism for knocking 0E or stopping the loom in ease any shuttle remains in either-box, or a full shuttle# box is brought into line with the race at the time a shuttle is tobethrown from the oppo{ site box, or in case'theshuttle is not thrown.

The invention also relates to the combination and'arrangement of l devices for knocking off or stopping a loom in case of v breakage of the yarn or filling; also to the construction of the friction-driving or clutch pulley with reference to lubrication of its journal-pin or gudgeon.

The ldrawing represents a loom embodying the invention. l Figure l-shows the loom in front elevation. Fig. 2 is a plan of it. Fig. 3 is a sectional elevation, taken on the line a: as.

a denotes the'frame; b, the breast-beam; c,

l the lathe; d, the crank-shaft; e, the cam-shaft;

fg, two sets of shuttle-boxes mounted upon rods h and sliding vertically, and having their movements imparted to them in the usual manner. i are the picker staves; 7c, the shuttle-race. The harness mechanism isnot shown, as no part of such mechanism has any imme- Each shuttle-box has itsy shuttle-binder l, hinged at m, pressed inward by a spring, j, and forced outward against the stress of the spring by the shuttle whenever a shuttle enters or is present in a box. For convenience, we show the two upper shuttle-boxes in line with the race for the iiightof the shuttle from one to the other. In front of the lathe is a rocker-shaft, fn, turning in bearings fixed to the lathe, and at the opposite or respective ends of this shaft are arms 0 p, thenpper end of each of which stands directly in front of the free end of the binder ofthe shuttle-box, which may be in li ne with the race, each arm being pressedup to ward the adjacent binders by the stress of a suitable sprin g. From the shaft n extends forward an arm, q, having at its end a hook, r, and in line with this hook is acatehs, at the end of an arm, t, extending backward from a knocking-off lever, u, which is pivoted at the under side ofthe breast-beam, as seen at u, Fig. 2, the endof this lever extending through the upright w, and in front ofthe shipper-lever rv, the shipper-lever being shown as `connected by a connecting-lever with thefriction-drivin g or clutch pulley y in such manner -`that when freed from its retaining-notch' it is pressed foriward by a spring and throws the-frictioadriving or clutch pulley out of connection with the gear and crank-shaft pulley z.

. When the shuttle is thrown from either box, the spring a2 turns the shaft a slightly, and

vvcauses the ends of the arms o p to follow the shuttle-binder, which is thrown in by its springs when the shuttle leaves its box. In this position of the shaft the hook i', at the end of the arm q, stands in the position seen atA, so that, just before the backward movement of the lathe is complete, and before the shuttle has reached the opposite box, the hook passes over the catch s without touching it. Y If, however, either box into which a shuttle is to be thrown is occupied by a shuttle, or if a box charged with a shuttle is broughtjinto line with the race at the end to which the shuttle is to bethrown, or there be shuttlesin both boxes at once, or byany reason the shuttle is not thrown, then the presenceof the shuttle causes the binder to be pressed out, turning the shaft so that the hook'is brought into direct line (in its path of movement) .with the catch, as seen at B and C, and as the lathe completes its backward movement the hook strikes the catch, drawing the catchlever forward, and causing the lever, by its movement, to throw the shipper-lever from ,its I notch, thus effecting the disengagement of the friction-driving or clutch pulley, and stopping the loom whenthe lathe is on the extreme back motion; in other words, unless each box on line with the lathe is empty directly after the picking takes place or should: take place, and while the Shuttle, if -.thrown, is on its iight, the protector will'stop the loom just as thelathecompletes its backward movement.

.Theshaft a has a dagger, b2ext endingfrcm it, and as the lathe beats up this dagger passes under a lever, c2, (under the brea'st-beam,) if the shuttle has been thrown and is in the box; but if the shuttle-boxes are both empty by reason of the entanglement or stoppage of the shuttle in its flight, or from any other cause, then the shaft will be held innormal position by reason of the shuttle-binder not pressing out'its'arm', and the point of the dagger will be heldin position to strike and 'move the lever `c2, which lever, being jointed to the lever u, imparts end movement to it, and causes the incline d2, at its end, to act against the shipper-lever, dislod ing it from its notch, disengaging the friction-driving or clutch wheel andjstopping the loom.

It will thus be seen that either in the event of acharged box or 'a shuttle being Vwrongly in' position at'either end of the race, asvthe lathe` beatsback, or in the event of the shuttie-boxes being, from.' any cause, both empty when the lathebeats up, the loom is instantly stopped, and beforethe next pick, so that the web'is preserved from injury. Y Also, inthe Hight of each shuttle it passes over two sets of prongs or fingers, ezfz, each extending from 'an armfgzor h2, pivoted in a bearing,"i2, each arm 'extending forward from the"'l'athe, and Vits fingers extending back over the shuttle-race and lying normally below the planeof` the top of thelracein a recess, j, in th'e top of the shuttle-race, so that the yarn or filling passes freely over the lingers. 1 Over the'ftwosetsof fingers ez f2,frespectivel y, extend two sets of prongs or fingers, 7c? l2, on the *front -arms of two levers, m2 a2, the front arms of 'said levers being normally thrown up by the stress of suitable springs, o2, and the rear arms'b'eing thrown up (when the lathe beats forward) by striking incliues p2, which inclines l Aare'onthe ends of arms qf,-pivoted at r3, the arms -being'thrown up when the lathe Kbeats Vforward (and into position to effect the descent of the prongs 7a2 lyby cams s3 on the crankshaft, the cams letting the inclinesdown at the -startback' of the lathe, so that the springs o2 can instantly throw up the prongs k2 l2. The

weight ofthe arms g2 h2, or the stress of suitable springs, holds the lingers 62j? above the` bottom of the recesses jl, and when the prongs k2 Zzdescend as the lathe beats np,'and the shuttle'having been thus thrown and the yarn thereby laid across the race,the prongs press down upon the yarn, and causethe yarn stretched across the ngers e2f2to press down said fin gers, thereby raising the arms g2 h2. Inj` the breast-beam, in' line with each arm g? h2, is'

la slide-catch, 113, sliding'loosely in a mortise, (12, cut through thebeam, each catch p3, at its frontend, being jointed to an arm, r2, extendin'g from' a rocker-shaft, 82, both -arms r2 exi tending from the same shaft s2, this shaft. having at its endv an arm, t2, extending alongside thev shipper-lever. e

'When'- the linger-arms g2 h2 advance toward the breast-beam their ends will enter the mor-. tsesvandjpass over the slideicatches, if `the 'the friction-driving or' clutch pulley. The absence of the yarn over either set of fingers e2 or f2 will of course permit the prongs above them to pass through the fingers; but as the web is narrower than the space betweennthe ngers e? and the iin gers f 2, andas the selvages are therefore `inside-of the fingers, one or the other set of fingers is always free when the shuttle is thrown, whether the yarn is broken or not. It will be obvious, therefore, thatsome device is necessary to keep the arml g2; or np at that end from which the shuttle has been thrown. For this purposerwe combine 'with each arm g2 or h2 and its fingers a mechanism kby which the binder of either box in 'line with the race, when empty, shall cause lthe armto .heheldup so that it will not strike the `catch,

said mechanism :being so arranged as toube thrown out of connection with the other arm by the presence of the shuttle in the opposite box. ln front of the opposite ends of the lathe are two rocker-shafts, u2 Q22, leach vhavin g an arm, wz, extending up and. resting at its top against, or standingy just in front of, thefree end of the shuttle-binder, in line with the race. At the inner end of each shaft is another arm, @extending up under an incline, z2, as seen at A, on thebottom of the finger-'arm g2 or h2 o f the corresponding end ofthe lathe.

Each shaft u2 e2 is held normally in position, or so that its arms w2 x2 are pressedvunder or toward the shuttle-binder and the incliner2 back of them; and when the arms are in these positions, which they can only lbe in case the shuttle-box back of either arm w2 be empty, the arm a2, acting-upon its incline z2, presses up the finger-arm so that it will pass overgthe slide-catch @sin-liuc with it, and impart no movement to such fcatch,andithe loom will continue to work. Now, as the shuttle vilies from either box, and lleaves suchbox empty,

the spring of the shaft u2 or Wunder such box is enabled topress the armw2 in, theshuttlebinder yielding; .and as Lthe shaft sovturns it of course carries the arm .r2-at the end of such shaft under the incline z2 above it, and thereby presses the a-rm g2 or h2 up so that it is in position to'clear the catch, thengers e2 or f2 being so presseddown and thearm. heldup t bythe arm :v2 org/2, instead ofbythe yarn, the

yarn being drawn up to vthe selvage, and not extending across -thevfngers At the same 'time the flight of the shuttle into the opposite boxcauses the binder of said Ybox to bepressed forward, thereby pressing forwardthe arm fw2 'in front of said box, turning theshaft @2.0i @2,

to which said arxnis attached, and moving the arin g2 or'v h2 of saidfshaft forward so thatv it passes out' from Vundei` the incline z2 above it. TheV arm g2 or'h2 over said incline z2 being thus released, it drops, causingl its fingers to rise; and,it` the yarn isdrawn over said fin gers by the-shuttlethe prongs k2 or l2, moving down against the yarn, will depress the fingers and raise thefarin, so that the arm will clear the catch p3 as the lathe beats up, and there is no stoppage of the loom but if the yarn is broken,

V then the arm g2 or 71.2 will remain down, there bein g. nothing to depress the ugers, and remaining-down will run against the catch p3 as the lathebeats up, and will stop the loom, as before described.

It will be Vobserved Vthat, each or" the shafts a2 or 'u2 andV its connections, with the 'fingerarnisand shuttle-binder over it, is independent'of the other'shaft-and its corresponding connections, 'and that by reason of such independence abreakage in the yarn at the throw -ot'f the shuttle -in either direction knocks oi'i' thelcom, the fingers e2 or f2 at the end of the race from which the shuttle is thrown being .moved fromtheirfnormal position, so that they cannot effect the stoppage while the iingersat the opposite end of the loom-a're.in

normalpositiom so that by failure of the yarn toextend overthem-they will beA in position toeifect the stoppage ofthe loom.

' It will thus'be seen'that whether the shutvtlerfailsfto` be' thrown Vor a shuttle be in a wrong box, or.two shuttlesbe iu opposite boxes, or the yarn be broken, or the shuttle fails to complete itsjflight,the^loom isl always vstoppedbefore Va new pick is thrown.
