To r117 t /mm it may concern/.-

Be it known that I, WALTER Funoniue Roman, a citizen of the United States, residing at Hopedale, m the county or \Vorcester and 5 State of Massachusetts, have invented certain new and useful improvements in \Vefh Replenishing Looms, of which the following i is a specification.

The object of the present invention is to substantially relieve the weaver from all attention to the weft-supply of a loom, thus placing the management of the weft in the same category with that of the warp.

In accordance with the present. invention the bobbins, cops, or other weft-carriers are suitably placed in appropriate. "(:ages at any convenient place in the mill, and the end of the weft-thread of each wcftcarrier is securedto a weft-end holder with which the l cage equipped. The loom is provided with a suitable magahine of sufficient capacity to hold enough of the weft-(nu'i'iers to serve the loom for an entire day. in accordance with this invention the loom can be supplied with weft-carriers eitl'ier after the mill has shut down for the evening or before it starts in the morning, so that the work of the. weaver in connection with the loom will be in no'wise affected or disturbed by the supplying of weft-carriers to the magazine. The loom is equipped with appropriate mechanism, such as is now well known in the art, whereby a weftcarrier is automatically placed in weavingposition. in the loom when ever the condition of the running weft demands. After each transfer of a weft-carrier into weaving position has been effected the active cage is then fed forward so as to bring a second weft-carrier automatically into op l oration, and after all of the weft-carriers of each cage have been exhausted a full cage is brought automatically into action. The emptied cages are discharged automatically into a suitable receiver, as are the spent weft-carriers after use in the loom. The 'weft ends are so securedto the cages as to avoid any. entangling of the various threads in the magazine to'avoid breakage of thread and when the corresponding weft-carrier is transferred to the loom to amount of thread wasted.

v minimize the I I l t t supplysideof the loom.

One embodiment of the present improvements is illustrated in the accoml'ianying drawings, in which- .l igure l is a side view of so much of a loom equipped with the present improvements as is necessary for an uiu'terstaiuling of the same.

The drawings illustrate only a few of the usual features of an automatic weft-replenishing loom.

In Fig. 1 the usual cam or'low shaft A of the loom is shown, and also there is shown a reciprocating transferrer B, which is pivoted at a and is held normally uplifted by a spring I). (See Figs. 1 and 2.) This transferrer is of a type now well known in. automatic weft-replenishinglooms, being similar in general characteristics to that set forth in the United States patent of Northrop, No. 529,940, November 27, 1894. It remains normally uplifted; but on the occurrence of a contingency requiring the automatic replcnishment of weft in the loom it descends and automatically transfers ,a fresh weftcarrier into weaving position in the loom. As is'customary in connection with the automatic transfer of a weft-carrier, such as a bobbin (J, the transferrer has two fingers c (I, (see Fig. 3,) which act, respectively, upon the weft-carrier near its butt: and tip, respectively. Fig. 8 illustrates the transferrer in the act of transferring a fresh weft-carrier into a shuttle l) in position within the contiguous shuttle-box on the lay E, the spent weft-carrier being ejected at the same time and falling through an opening in the lay into a suitable receiving-chamber 0. below, as indicated in Fig. 3. in these respects the operation of theloom is similar to that of the sent well-known Northrop weft-replenishing loom.

-ln accordance with the present invention the spare weft-carriers are initially placed insuitable holders, which are here called cages. One of these cages F is illustrated in detail in Figs. 9 to 17, inclusive.

Each cage is adapted to receive and hold a pluralityof weftcarriers, as shown being capable of holding four weft-carriers.

The cage is equipped. with appropriate devices to receive and hold the welt-carriers, and these deviceswvill be hereinafter particularly describe-(1. At the time the welt carriers are placed in the cages the weft end of each wcltcarrier is'secured to a weft-end holder G, with which the cage is equipped, andpreicrably there is a separate weft-end holder for each. weft-carrier, as illustrated in Figs. 9, 10, and .17. These cages thus filled with weft-carriers are stacked within a suitable iixcd vertical magazine H, which is mounted on a iixed support I on a stationary part of the framework of the loom, such as one end of the breast-beam, as illustratcd in Figs. 1 and 2. This magazine can be of any height-for holding any desired.

number of. the cages, and this is indicated in Fig. 1- by breaking: off the top of the magazinc; azinc is made of such height as to receive a stack of cages in suilicient number to furnish enough Weft-carriers to mrtainly supply the loom for an entire da Figs. 1, '7, and 8 illustrate two of the weft-carriers located within the reservoir-chamber of the magazine, the upper cage resting: by gravity nnonthe lower one, and inspection of these Conveniently and desirably the map g figures indicates how any desired number of the cages can be stacked upon one another within the magazine.

The magazine-chamber is open at its bot tom and there communicates with a horizontal guidey'ay for the forward feed ofthe cages. As shown in Fig. 4, this guideway has horizontal guides J J, on which the lowermost and active cage rests and by virtue of which the active cage SUPPOIES the superimposed stack of cages locate within the magazine. The guideway thus constituted extends forward beneath the front wall of the magazine a sullicient distance to support the'active cage until all of the weft-carriers to the loom. The feeding mechanism is so arranged that the active cage is fed forward automatically the distance between 'two successive Weft-carriers held by it after each transfer of a weft-carrier from the cage to the loom. When the lastwei't-car'rier in the active cage is thus fed into registering posi tion below the transierrer and ready to be acted upon by the transferrer when next called into operation by the condition of the running weft, the active cage is removed from beneath the superimposed stacli of cages in the magazine, whereupon they drop down by gravity, the then lowermost oi the stack of'cages taking its position on the guides J J under the control er the feeding, mechanism. This feedin g mechanism will be hereinafter described in detail. The spent cage exhausted of its weft-carriers is fed step by step forward by the action of the feeding mechanism until it comes entirely over a fixed delivery-chute K, (see Fig, 3,).whereupon the spent cage slides down by gravity into suitable receiving-chamber f lmneath.

it will bc'noted that during the descent of the several cages within the magazine and during the forward feed of the active cage under the control of tie automatic step-by step feeding mechanism each weft-carrier, maintains a definite position relatively to its weft-end holder, so that there is no danger of the wefbtlvreads becoming entangled with each otlter or of the individual weft-threads becoming detached or catching on any part of the loom. 1 Another important feature of tie Weft-end'liolders is th at they are located at the inner side of the -I'nagazine-that is to say, at the side of tl=e magazine nearest to the selvage of tie cloth-with the result that each weft-end lolder is between its Weft-carricr and tie cloth selvagc. Hence wl'en a weft-carrier is inserted into weavin position in the loom tlere is a minimum length of weft-t. read left between tle Weft-fend l older and the selvage of the cloth to behut olli' and wasted. 'l is of importance in the case of expensive reread.

In describing the details of the improveheld by it have been transferred in succession I lOO l-IQ

ments'the construction of the weft-cages will first be considered, en the construction and mode of operation of the feeding mechanism, then the discharge oi" the spent well-cages, and finally illustrated modifications will be considered.

Each cage is composed of two malleableiron castings g g, (see Fig. 9,) connected togetlter by a sl eet-sieel top plate /i, (see Fig. 10,) the top plate and side castings being suitably riveted togetler. There is thus formed 2a strong substantial but ligi t cage capable of being readily handled without injury. At its two opposite sides and at the exterior it is provided with oppositely-projecting lugs 11 'i integral with the side castings, which cooperate wit ii the feeding lllOC- anism. The top plate I). is inade in skeleton form, by forming tl erein holes j, w.- ich reduce its weiglt, and at ti'e same time the holes near the sides allord passage for the fingers ad of the transleirer. The cage is suitably formed beneath the top plate to receive and securely. hold the weft-carriers, while at the same time permitting their ready removal under the action ot' the transferrer. Each weft-carrier is lteld both at butt and tip. The inner side casting g is provided with suitable sockets L L, (see Fig.

14,) one for each butt of the weft-carriers which the cage is adapted to hold. Preferably each cage is capable of holding a plural- -i.ty of weit-carriers, as illustrated holding wcftearrier is held by its tip in the.

\3 four weft-carriers. Each of these butt-holding sockets L has an open mouth at tlzelower end to permit the downward discharge of its weft-carrier, and it is of appropriate shape to receive and h old ti e butt of the welt-carrier, as, further illustrated in Figs. 15 and 17. in addition each socket has recesses Z, into which. the end;ring m of a weft-carrier fits when in place. Ti ese recesses Z Z are at oposite sides of tie socket, and t] e distance etween their lower corners n n is less than the major diameter of ring m. Conse quently the butt of tie weft-carrier cannot be displaced downwardly except by a slight but sullicient endwise movement of the weft carrier to clear the ring in from the recesses Z Z. This eilectuall y prevents any accidental discharge or displacement of the weft-mu riers in the cage. Nevertleless under tlc force applied by t e transfcrrer tle weft-carrier is readily displaced endwise, so as to become freed from these retaining-recesses, the manner in which the weft-carrier tip is held permitting this endwisc movement. Each cage by a ivo'ted spring-pressed latch M. (Best shown in Fi 's. 12, 13, and 15.) As here sl'zown, each latch M is pivotally connected near its upper end to the cage, and at its lower end it is pressed inwardly by a spring. I On its innor face each latch has a circular recess to receive the tip of the weft-carrier, as clearly shown in Fig. 15. The inner face of the lower end of the latch M is beveled or rounded at o in Fig. 15,50 as to facilitate il'e placing of the weft-carriers in pla we in, tee cage. T1 e wel'tcarriers are readily placed in position in the cage. Conveniently a w'eft-carrier butt is first placed in one of the sockets L, and i110 tip is then brought against the beveled end 0 of the latch, thereby pressing tl'e latch back against. the tension of its spring, so that tle tip of tlic \\'ettcarrier seats in titc recess intended for it. Tltereupon t e spring restores ti o latch to its holding position. As shown in Fig. 13, t re latch has side flanges p, wl ich aid in guiding and directing the weft-carrier tip into place. When the transi'errer acts, the latch M yields, thus permitting slightendwise movement of tlie \y'eltearrier to free its ring m from the socket-recesses Z l, and the weftcarrier is then thrust downwardly by the translerrer into the shuttle beneath, as illus tratcd in Fig. 8.

The weft-carrier illustrated is one of wellknown construction used in the Northrop loom, having the projecting rings at at its butt, wlich enable it to be grasped and held by bobbin-lolding aws in the shuttle, as set forth in the patent of Northrop, No. 454,807, June 28, 180i.

The shuttle employed is one of the automatic-tln'eading type such as is set forth, for example, in the Northrop patent, No. 454,S()T*-and in connection with such a shuttle the welt-carriers are so placed in the magazine that their butt-ends arc toward the selvage oi the cloth--tl1a t is to say, when the cages are in place in the magazine, as illustrated in Fig. 2, the weft-carrier butts are at the inner side of the magazine and are hence presented toward the adjacent sclvage of the cloth. These considerations detsrmine the location oi the weft-end holders G on the cages. Each cage has preferably as many welt-end holders as it holds welt-carriers, as illustrated in- Fig. 1]. The end of the thread of each welt-carrier is first led toward the weft-carrier tip and thence through an open thread-guide 1 in the latch M, (best shown in Figs. 12 and 13,) and the thread is thence led alongside the unit-carrier (see Fig. 9) to the inner side ol the cage. The thread then passes through a notched thread-guide r on the edge ol' the inner side (see Figs. l) and 11) and thence upwardly through a depressed tln'ead-guiding recess 8 in the outer Face of the inner side 1 (see Figs. 1] and 7) to the weft-end holder G. This holder, as shown, consists of a strip ol" sheet metal with its ends outwardly bent and secured by a screw to the outer wall of the inner side, as

best shown in Figs. 9, 10, and 11,. The end ot' the thread is secured to the holder between it and the outer wall of the cage side. The purpose of the recessed thread-guides r s is inf-2g to ensble the thread. to be kept away from the edge and well of the cage, so as to avoid any chafing of the thread during the occupancy of the magazine by the or during its feed. The thread is thus fully protected at all times. The circumstance that the thread is led first toward the tip of the woftcarrier, thence around a thread-guide, such as '9, and thence along the weft-carrier to a holder located between the butt of the weftcarrier and the selvslge of the cloth is a mat ire-r of importance. the weft-carrier to the shuttle the initial movement of the weft-carrier frees the thread from the threcd=guide (1 near the Weft-carrier tip, thus leaving slack the thread extending from said thread-guide g to the thread-holder G. This amount of slack thread is sufficient to enable the weft-carrier to be deposited into. theshuttle on the lay Without involving any strain on the thread, hence avoiding thread breakage during the transfer. At the some time, owing to the location of the weftend holder between the butt of the weft-carrier and the selva e of the cloth, there is only 9. short length oi "thread which is Wasted.

During the entire occupancy of the cage by the'weftesr1ier the weft-end holder goes with the weft-carrier and always occupies the some relation thereto until the transfer to the loom is made. There is nothing to chute the thread or to cause it to loosen or become slack, so that there is no entsngling of the threods'of the 'difi'erent weft-carriers" and no damage occurs to the threads. I At the same time when all of the weft-carriers have been transferred from the cage to the loom and the the loom is equipped,-as'customarily, with a throadruttor for cutting the weft between the ad acent selvsge or the cloth and the welt-end holder after each weft-carrier has been inserted into weaving position in the loom. lhcse urges are conveniently supplicd with weft-carriers, and the weft ends are readily and conveniently secured. This Work can be done rapidly by helpers at any convenient place in the mill away from the looms and at small expense.

Each cage is detachable from the loom, and its retaining devices grasp and firmly hold-the contained weft-carriers, so that the cages can be handled freely and in any position without danger of accidentally displacing the weft-carriers.

At any convenient time the londed cages are carried to the looms and stacked up .in the loom-magazines. Each magazine is open at its top and also at its outer side, as

During the transfer of illustrated in Fig. 2. As illustrated, the magazine is composed of sheet metal bent into appropriate shape to receive and retain the cages lying horizontally. The cages can be inserted either through the open top or through the open outer side. This open outer side has marginal columns N O to prevent the outward displacement of the cages. v

The lowermost cage when resting on the horizontal guides J J has its feed-lugs i i 7 5 within range of a step-by-step feeding mechanism which feeds the cageforwa-rd whenever the trsnsferrer acts. The feeding mechanism comprises two horizontal sliding racks P P at opposite sides of the magazinesupport I, as clearly shown in Fig. 4, each sliding rack P being suitably guided in the support I, as shown in Fig. 5. -These two rocks P P slide in unison through their rackteeth, (see Figs. 1,7, and 8,) meeting with 8 pinions t at opposite ends of a rotary shaft Q. At its forward end each rack has a. spring-controlled pivoted pawl R, which is adapted to engage the feed-lugs'i 'i on the cage, as shown in Fig. 4. The inner rack i go has pivoted to it an actuatingdink S, which at its forward end has a slot u, (see Fig. 8,) into which enters a laterally projecting pin 1) on an upwardly-projecting arm of the trans lerrer B. Normally the transferrer, ect'ust- 5 in.g-'linl ,snd racks occupy the position shown in Figsfel and 7.

This stop is approprimetrical in a horizontal plane. This is 30 ately located, as indicated by dotted lines in shown in Fig. 2.

If it should be attempted to turn the cage upside down and wrong side out, then the cage could not be inserted, be cause one of its tlnead-holders would come in contact with the larger column N, and hcncc prevent insertion. By reason, therefore of this unsymmetrical relation between the cages and the n'iagazinc when regarded horizontally it is impossible to place the cages in the magazine except correctly.

'As a further precaution the feed-luqs are so constructed that it the cages shou d bewrongly placrd within the magazine, (as might be the case should the front column N and above the feed-lugs "i 'i. This springbrake steadies the active cage throughout the occupancy of its active position. Each cageis thusi'ed forward step by step until all of its weft-carriers have been transferred to the loom. When the last weft-carrier of the active cage is brought into register with the transfer-rel, said cage no longer affords a sup port to the cages above, within the magazine, and accordingly they drop down by gravity, thus bringing a fresh weft-cage within reach of the feeding-pawls.

, it is obvious that many. changes may be made in the various features of this invention Without departing from its main principles.

The transferrer may be set in motion by any. of the Well-known mechanisms now known in the art. its action maybe controlled by the exhaustion of the running Weft, by the approaching exhaustion of the running weft, or by time or pattern mechanism.
