LOOM.

SPECIFICATION forming part of Letters Patent N o. 596,854, dated January 4, 1898.

Application filed February 3, 1897.

To ttl whom, il; may concern:

Be it known that I, EDWARD WV. DAVEN- PORT, of Hopedale, county of iVorcester, Massachusetts, have invented an Improvement in Looms, of which the foilowing description, in connection with the accompanying drawings, is a specification, like letters and iigures on the drawings representing like parts.

This invention relates more particularly to that class of looms wherein the filling having been exhausted from the llingcarrier or ally supplied to the shuttle, the spent fillingcarrier being ejected from the shuttle, as in the Well-known Northrop loom.

In United States Patent No. 527,014, dated October 2, 1894, means Were provided to prevent a weft end from being left between the selvages, said means cooperating with iillingsupplying mechanism acting to automatically supply to the shuttle a fresh supply of filling when the filling in the shuttle has been nearly exhausted or exhausted to a predetermined point. The amount of lling present in the shuttle is ascertained by a detector, which enters the open top of the shuttle at each beat of the lay and feels or engages the tilling on the bobbin or cop generically termed the lilling-carrier. In such construction the end of filling from the spent and ejected filling-carrier extended thereto from the selvage of the cloth, and so, too, when the fresh lilling-carrier was inserted and the shuttle thrown an end of filling would be left beyond the selvage and between it and the point of attachment of the filling end to the iillingsupplying mechanism. Such filling ends are apt to become Woven into the fabric, and in United States Patent No. 553,814, dated J anuary 2S, 1896, means were provided for parting the spent iilling close to the selvage, and also to part the new filling adjacent thereto, so that no long loose ends of filling should be left beyond the selvage, and in that instance also the amount of lling on the filling-carrier is detected by a detector entering the shuttle at its open top and feeling the iilling.

In this present invention I have provided a feeler or detector movable with the shuttle itself to detect the gradual decrease of the filling on the lling-carrier, the operation of my invention.

Serial No, 621,730. (No model.)

the detector being sodelicate that when the last portion of thread is being unwound the detector Will come into such position as to through suitable intervening devices actuate i the transferrer and transfer a fresh supply of illing into the shuttle. By this means only a very short length of filling is left on the ejected filling-carrier and considerable Waste is prevented in consequence.

In order to render the action of the detector as fine orv delicate as possible, I have pro-V vided the cop or bobbin, preferably in its cone, with a recess which is opposite the detector and which may be entered by the latter when the thread on the filling-carrier is wound off sufficiently to expose the entrance to said recess. Then the detector is thus free to move, it is made operative to set in motion the transferring mechanism.

As the detector is mounted at a fixed point on the shuttle, it is essential that a iilling-carrier When transferred to the shuttle shall al- Ways have the same position, so far as its re cess is concerned, relative to the detector, and for this purpose I have shown the base of the filling-carrier as so constructed that it will always be placed in one position in the shuttle. This particular construction, however, is not broadly of my invention and is not so 8o herein claimed, the same forming the subjectmatter of United States Patent No. 587,652, dated August 3, 1897.

Various novel features pertaining to myinvention Will be hereinafter fully described, and particularly pointed ont in the claims.

Figure 1 is a perspective view of the fillingsupplying mechanism and a sufficient part of the lay and breast-beam of a loom to be under stood with my invention embodied therein. 9o Fig. 2 is a perspective view, enlarged, of the shuttle-box at the end of the lay adjacent the illing-supplying mechanism, showing. some of the mechanism cooperating with the detector and also the controlling meansfor the g 5 thread-parting devices. Fig. 3 is a partial perspective view of a iilling-carrier adapted to be used in connection with the detector in Fig. 4 is a longitudinal sectional view of a suicient portion of the loom roo with the lay back, the transferring mechanism and the controlling means being in nor mal position. Fig. 5 is a like view, the lay, however, bein g forwa1'd,with the transferring mechanism in position transferring a fresh lling-carrier to the shuttle. Fig. 6 is a perspective view of one end of the shuttle with the filling-carrier removed, showing clearly the detector or feeler. Fig. 7 is a like view of the transferrer, actuator, and the control.- ling means for the thread-parting devices, said means being governed by the detector. Fig. 8 is a detail in side elevation of the outer side of the shuttle, showing the detector in position. Fig. 9 is a horizontal sectional detail of the shuttle-wall, the detector, and a portion of the shuttle-box with the means for imparting detecting movement to the detector. Fig. 10 is an outline view in plan of the shuttle, the filling-carrier, and the detector when the latter is in detecting position. Fig. 11 is a perspective view of the temple and` temple-stand with the thread-severing device carried thereby. Fig. 12 is an enlarged detail in elevation of the latch-bunter for operating the severing device. Fig. 13 is a longitudinal sectional view thereof on the line ac, Fig. 12; and Fig. 14 is a partial sectional view of the thread-severing device.

The loom-frame A, the lay A3, breast-beam A40, the filling-supplying mechanism, including the disks or plates a a', the former having a series of notches or pockets and the latter a series of grooves and springs a2, the stand a7, supporting a fixed stud a, on which the feeder rotates, the ratchet-teeth a, the cooperating pawl e on the pawl-carrier e, having a tailpiece e2, moved in one direction by the spring e3 and in the other direction by a roller e4 on the lay to rotate the feeder step by step whenever a lling-carrier has been transferred to thereby put the endmost filling-carrier of the series against the stop 13, the detent e5, the stud f on the stand a7, upon which stud is mounted the hub of the pusher f', having a finger 2l to act against the tip of the filling-carrier, the elevating-spring 22 for the pusher, and the weft-end holder b may be and are all substantially as represented in United States Patent No. 529,940, the parts in practice being operated as therein provided for.

The arm f6, attached to the stud f, has pivotally mounted at or near one end thereof on a stud f7 a tip supporting or directing device f8, (see Figs. 4 and 5,) having a lug 2, normally kept in contact with a stop 3, projecting from the arm by a suitable spring, (not shown,) all substantially as in United States Patent No. 529,942, to which reference may be had.

The feeder head or disk Ct is provided in.

each of its notches with a radially-disposed guide @15, so that when the filling-carriers B (see Fig. 3) are put into the feeder the slots B in the heads of said carriers will each embrace a guide, preventing any rotative movement of the carriers while in the feeder or while being removed therefrom by the pusher f.

In Fig. 3 the head of the filling-carrier is shaped to present two flat or secant surfaces B2, whereby when a carrier is removed from the feeder one of said flat surfaces tends to and will contact with the flat upper side of a carrier then in the shuttle S, the head of the carrier being provided with metallic rings c, of usual construction, such construction being shown in and forming the subject-matter of application, Serial No. 617,869, referred to.

Inasmuch as it is essential to my invention that the filling-carrier will always enter and be held in a certain position relatively to the shuttle, I have'adopted the hereinbefore-described construction for attaining such result. Referring to Figs. 6, 8, 9, and lO, the open shuttle S has mounted on its inner wall in suitable ears 5 a pintle d, serving as a fulcrum for a detector or feeler, (shown as a finger CP2) preferably convexed on its inner side near its tip, as d', and laterally movable in a longitudinal slot 6 in the shuttle-wall.

Extended oppositely from and preferably below the detector and movable therewith l have provided an arm cl2, preferably shouldered on its outer side, as at d3, and laterally movable in a longitudinal slot 7 in the shuttie-wall, the arm and iinger presenting a lever of the first order, said arm d2 being termed in the claims a controller for the transfer'- ring mechanism.

The detector is adapted to coperate at times with a recess, as BX, Fig. 3, in the conical portion of the filling-carrier or bobbin B, two such slots being preferably' provided opposite each other and longitudinally extended, the thread wound upon the carrier normally covering the slots and preventing pivotal movement of the detector toward the longitudinal center of the shuttle sufficient to operate the transferrer. Vhen, however, the thread has been drawn off or unwound from the carrier until a sufficient portion of the recess BX has been uncovered, then the detector can and will, as will be described, enter the recess and through the arm d2 and suitable intermediate devices effect the operation of the transferring mechanism to transfer a fresh filling-carrier to the shuttle.

A light spring s, Fig. 6, normally acts upon the detector to press it outward and away from the mass of thread o n the filling-carrier while the shuttle is passing through the shed and to normally maintain the detector in inoperative position.

To more certainly guide and retain the lling-carrier in proper position in the shuttle, I have secured to the latter at the jaw end, as by screw 8, Fig. 6, a bent wire 9, extended between the jaws and in a vertical plane to be embraced by the slots B' in the head of the filling-carrier as the latter is transferred to the shuttle-jaws.

The back S of the shuttle-box, Figs. 1, 2,

zgo

and 9, has preferably pivoted thereto at c2 av finger c3, preferably of spring metal and con- Vex in the direction of its length toward the exterior of the shuttle-box, said finger being acted upon by a leaf or other spring s', secured to the back SX at one end. The finger o3 is so located that when the shuttle enters the shuttle-box the detector dx will be engaged by said finger and will be pressed inever, it is supposed that the thread has been sufficiently drawn off from the filling-carrier to leave exposed the slot BX therein, so that as the shuttle enters its box the finger c3, acting on the detector, has pushed the latter into said recess, such movement of the detector throwing out into operative position the arm d2. As the said arm cl2 is thrown ,out before the shuttle comes to a stop in the shuttle-box the continued movement of the shuttle will cause said arm to engage and move the upturned arm g of a rock-shaft g', mounted on the lay, the latter being slotted at the rear of the shuttle-box, as at 9, Fig. 2, to permit the reduced upper end of the arm gto project in the path of the arm d? when the latter is thrown out.

In Fig. 7 I have shown on an enlarged scale the mechanism controlled by the rocking of the shaft g. A bracket or stand G has an enlarged portion G', which forms a bearing for lthe rock-shaft and also for a buntenshaft h. The controlling-shaft g has fast thereon at its outer end a collar g2, to which is attached oneend of a spring s2, the other end being secured to the part G' of the stand and tending to normally turn the shaft in the direction of the arrow 12, Fig. 7, said shaft at the opposite side of its bearing being provided with a cam g3, having high and low portions 13 and lfl, respectively. The buntershaft 7i has inserted therein the threaded shank of a bunter H, held in adjusted position by a set-screw hx in the end of the shaft, and a resetting-pin h', as it'may be termed, is fixed in the said shaft. A collar h2, rigidly secured to the bunter-shaft by a suitable set-screw, as 15, is provided with a lip h3 to coperate with the cam g?, the lip in Fig. 7 being shown as resting on the high part 13 of the cam and held thereon by the action of a spring S3, one end being fastened to the collar 71,2 and the other en'd being suitably fixed `to or bearing against the stand G.

The parts are shown in Fig. '7 in normal position, but when the detector hasmoved the arm d2 into operative position the latter engages the upturned arm g of the rock-shaft g to rock the shaft in the direction opposite to the arrow 12 as the latter continues its movement in the shuttle-box, thereby withdrawing the part 13 of the cam from beneath the finger h3, the bunter-shaft then being free to turn under the action of the spring s3 to raise the bunter into operative position, and as the lay comes forward to engage a dog f1.0, shown as an arm secured to the pusher f and preferably notched atf12 to receive the bunter, the pusher being thereby depressed, as shown in Fig. 5, to transfer a fresh lling-carrier from the feeder to the shuttle, the transferred filling-carrier engaging and ej ectin g the spent filling-carrier, as in Patent No. 529,940, the detector being withdrawn from the iillingcarrier by its spring s before the transfer is effected. As the lay moves forward after the bunter-shaft has been turned into operative position, as described, the resetting-pin h will, in the forward movement of the lay, pass beneath and temporarily lift a trip h3", shown as U-shaped and embracing the lower part of the stand a?, to which it is pivoted at h4, and when the lay moves back the pin will strike the front edge of the trip and will be turned thereby to roclr the bunter-shaft 7i in the direction of the arrow 16, Fig. 7, thus lowering thebunter and raising the finger h3 from the part 14 of the cam g3 and above the part 13X, so that the spring s2 will rock the shaft g into normal position, thereby resetting the parts. The trip 71,30 can swing forward sufficiently to permit the passage of the resetting-pin 7t',as the latter when in abnormal position goes forward with the lay, but said trip acts as a rigid projection on the return or opposite movementof the pin. A lever h5 is pivoted at h6 to the bracket or stand G, one end of the lever, as k7, being locatedin the path of movement of an ear h8 on a collar h9, secured to the bunter-shaft, so that when the latter is turned into operative position, as described, the outer end of the lever will be elevated.

On the front side of the lay I have rigidly secured a guide-plate K, (shown separately in Figs. 12 and 13,) provided with vertical parallel ribs It, the cuter face of the said plate between the ribs being longitudinally recessed to leave a shoulder 75X. (See Fig. 13.) A bunter, shown as a slide-block 7c', preferably beveled at its lower end, as at k2, is longitudinally slotted at k3 to receive a pin ki, secured in the guide-ribs Zr., so that` the block k may slide vertically between the ribs, the pin being located suiciently far from the outer surface of the plate as to permit slight rocking motion of the slide-block. A spring s4, held in the recess h5, acts to normally throwthe upper end of the guide-block outward.h The guide-block is provided with an outwardly-projecting pin or stud 7156, beneath which extends the outer end of the lever h5,

as clearly shown in Figs. 1 and 2sc that IOO IIO

when the lever is rocked on its fulerum by the operative rotation of the bunter-sl1aft 7i the outer end of the lever will be elevated, carrying with it the slide-block k', the lower end of the latter at such time being raised above the shoulder kx.

As the bunter-shaft is not returned to normal position until the lay moves back, the lever h5 will retain the slide-block raised until the lay is moving back, and during the time the block is so held up the spent or eX- hausted filling-carrier will be ejected and a fresh filling-carrier transferred to the shuttle, and the thread-severing mechanism will be operated to sever the lling end left by the ejected filling-carrier.

I have herein shown a severing device mounted so as to move with the temple, the cutting mechanism being so shaped that it normally stands in the plane outside of the path of the iillin g end,its movement being such that when operated it will sever the filling end just before or as the temple begins to move with the lay.

The temple-stand M, adapted to be secured to the breast-beam of the loom, the blade-bar M', having the pod M2, the cap M3, the heel M4, attached to the pod, and the toothed temple-roll T, between the pod and the cap and turning on the usual pivot, are and may be all as usual, the stand M in practice containing a spring to act upon and normally keep the bar M' pressed inward toward the lay. The pod is slotted to receive a steel blade fm, toothed on its upper side, as at m', and the shank or bar M has an ear mx, preferably recessed in alinement with the said blade to receive the body of the movable cutting-blade fn, slotted at '70 and pivoted in the ear mx on a pin nx, said outer end being longitudinally slotted at n2 to receive the fixed blade m when the upper blade is moved. The body of the blade n is provided with a depending heel n3, preferably roughened or cor-v rugated on its front face, as at n4, Fig. l1, and acted upon by a suitable spring S5 to normally throw the heel forward, and thus raise the blade n to leave an open space between it and the Xed blade m, the blade ln being also moved forward bodily on its fulcrum nx. In its normal position the heel n3 is somewhat nearer the breast-beam than the heel M4, as best shown in Fig. 4, so that if the loom is running properly the lay will engage the heel M4 and will move the temple forward without operating the cutting mechanism. When, however, the transferring mechanism has been operated, as described, to transfer a fresh supply of filling to the shuttle and the slide-block lo has been raised by the lever h5 into operative position, the upper end of said block, which may be serrated, as at 708, will engage the heel n3 and press the latter back as the lay comes forward, operating the movable cutting-blade to act upon the lilling end and sever the same. This takes place the first time while the slide-block lo is upheld by the lever h5. As the lay goes back it will be remembered that the lever h5 returns to normal position and its'support is therefore withdrawn from the slide-block, but the spring s4 throws the upper end of the block out, so that its lower end will swing in to be engaged and held by the shoulder kx of the plate K. As the lay comes forward on its next stroke the heel n3 will be again engaged and operated by the slide-block still in its path, and the cutting mechanism will be operated a second time, this time acting upon the filling end between the selvage of the cloth and the weft-end holder b. In its second engagement with the heel the slideblock will be again rocked on its pivot, withdrawing its lower end from the shoulder kx, so that when ythe lay goes back for the second time, withdrawing from the said heel, the block will be free to drop by gravity to its normal position.

It will be obvious from the foregoing description that the filling-end cutter is operated only when the transfer of filling takes place, and then. it is operated twice in succession, the first time to sever the filling end left by the ejected filling-carrier and the second time to sever the filling end extending from the cloth to the filling-feeder, the shuttle with its new supply of filling having taken its first iiight across the lay;

By providing the filling-carrier with a recess to be entered by the detector the operation of the latter is made more delicate and the amount of filling left on an ejected carrier is much less than would be the case if the detector was set to operate when the thread mass was reduced to a predetermined diameter, and by making the recess in the cone or base portion of the filling-carrier I insure the operation of the detector to set in motion the transferring mechanism only when nearly all of the thread has been withdrawn from the carrier. So far as I am aware this feature of my invention is broadly new, and it is also broadly new to operate a threadcutting mechanism by a latch-bunter,7 as the slideblock 1c may be termed.

The detector or feeler is operated at the same side of the loom as the filling-supplying mechanism, thereby reducing the number and size of the parts of the intervening devices and making the operation quicker and more uniform.

The detector is intermittent in its action, inasmuch as the devices for giving it its detecting or feeling movement are located outside and independent of the shuttle and at the side of the loom adjacent the filling-supplying mechanism.

My invention is not restricted to the precise construction and arrangement herein shown and described, as it is obvious that the same may be modified or changed in various particulars without departing from the spirit and scope of my invention.

I do not herein broadly claim the severing IIO device mounted on the temple and comprising a xed blade and a longitudinally-movable and rocking blade, as the same is not broadly of my invention.
