To aZZ whom it may concern.-

Be itknown that I, JONASNORTHROP, a sub ject of the King of Great Britain, and a resident of Hopedale', county of Worcester, State of Massachusetts, have invented an Improvement in Automatic Filling Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts' This invention relates to looms provided with mechanism for replenishing automaticallythe running shuttle with filling when necessary without interfering with the continuous operation of the loom-such, for instance, as forms the subjectmatter of United States PatentNo. 529,940and myinvention is used in connection with so-called feelerlooms of the general class mentioned.

In a feeler-loom filling replenishment is effected priorvto complete exhaustion of the supply carried by therunning shuttle, thereby obviating the formation of one or more empty or partly-empty picks. An automatically self-threading shuttle is used in such loom, and means have been provided to sever the old filling end and the fresh filling end adjacentthe edge of the cloth to avoid the weaving of loose thread ends into the selvage of the cloth, and a part of the severing means is usually mounted on the shuttle-feeling device. While such apparatus has been highly successful and has gone into extensive use, certain practical defects are occasionally made manifest, interfering with the perfect operation of the 100m. Sometimes the shuttle fails to thread or "when" threaded the-filling is at times looped aud'thrown forward out of the threading-passage, causing additionalopera'tions of the replenishing mechanism. So," too, the thread-severing means will not operate as promptly as desired upon filling replenishment, or such means may fail to sever the thread, so that the latter is broken and the ends stick out from the edge or are woven into the cloth.

My present invention involves a feature which is, so far as I am aware,.broadly ne'w viz. the positive and automatic union or connection of the old and fresh filling ends-'- whereby a continuous filling is provided. As

the path of the replenished shuttle in ample the fresh filling-supply is being transferred from the filling-feeder to the running shuttle the filling end is cut and held, and the old filling end is also cut between the delivery-eye of the shuttle and the outgoing filling-carrier and held. These two ends are then brought together and united automat ically by twisting them together, in the present embodiment of my invention the entire 60 operation being effected while the shuttle is in the replenishing shuttle-box, the united filling being released and. the devices which have acted thereupon being withdrawnfrom 5 time to permit it to be picked from the re plenishing shuttle -box. There are manypractical advantages attendant upon such an apparatus, as will be plainly manifest hereinafter. A solid shuttle can. be used as distinguished from an automatically self-threading shuttle, avoiding the difficulties referred to as sometimes attendant upon the use of the latter. Again, the ordinary shuttle-feeler thread-cutter is dispensed with, and as a continuous thread of filling is laid no ends are or can be left extending out of the cloth.

In brief,.the Operation of the mechanism hereinafter to be described and which embodies one practical form of my present invention is substantially as follows: When the fresh filling carrier or supply is transferred to the shuttle, the spent filling-carrier is ejected therefrom, leaving a thread of filling extending from the cloth through the shuttle-eye and down into thereceptacle for ejected filling-carriers or bobbins. The filling-uniting device descends with the transferrer, and the fresh filling end is grasped and severed between the point at which it is held and the filling-feeder. This held end of fresh filling is carried down into a chamber in the shuttle, and the outgoing filling end is caught and held and severed from the portion extending to the ejected filling-carrier. The two ends of filling-the old and the new are automatically laid across each other in the shuttle-cham her, and in this position suitable I jaws close upon them. The tra-nsferrer continues to descend untilthe fresh filling-carrier is properly inserted in the shuttle; but during the latter part of such movement one of the jaws referred to is moved or slid 1ongitudinally upon its fellow. Such relative sliding movement of the jaws while closed upon the filling ends twists or rolls the latter securely together. The transferrer then rises and the jaws are opened automatically, releasing the united filling ends between the shuttle eye and the delivery end of the freshly-inserted filling-carrier, and the jaws then return to normal position and are set automatically in readiness for the next operation. Thereupon the shuttle is picked in usual manner, carrying the united fillingthread into the cloth The various novel features of the invention will be described in detail in the subjoined specification and particularly pointed out in the following claims.

Figure l is a right-hand side elevation and partial section of a portion of an automatic filling-replenishing loom, the section being taken on the irregular line 1 1, Fig. 2, looking toward the left, the outer plate or disk of the filling-feeder being broken out, the transferring mechanism and the means for severing and uniting the filling ends being shown in normal position. Fig. 2 is a front elevation of a portion of the apparatus shown in in Fig. l, the outer end of the filling-feeder being indicated by dotted lines. Fig. 3 is a top or plan View of the left-hand side of the loom, showing the filling-feeder and cooperating devices. Fig. 4 is an enlarged perspectiveview of the means for severing and uniting the severed ends of the old and new filling viewed from the right-hand side of the loom. Fig. 5 is a similar view, but taken from the opposite or inner side. Fig. 6 is a detail similar to Fig. 1, but showing the filling-replenishing operation as initiated, the transferrer being about to engage and re move the fresh filling-carrier from the fillingfeeder, and the fresh filling end has been grasped and severed with the part-s in readiness to grasp and sever the old filling end. Fig. 7 is a like detail view, but the transfer of the fresh filling has been completed, the old filling end has been severed, and the two severed ends have been rolled or twisted together, and thereby unit-ed, the subsequent movement of the parts back to normal position causing first the release of the united filling and thereafter effecting the setting of the mechanism in readiness forasubsequent operation. Fig. 7 is a detached detail of the cam-plate shown in Figs. 1, 6, and 7. Fig. 8 is an enlarged inner side elevation of the filling parting and uniting instrumentality in the position shown in Fig. 1. Fig. 9 is a rear elevation thereof viewing Fig. 8 from the left. Fig. 10 is a vertical sectional view on the line 10 10, Fig. 9, looking toward the right. Fig. 10 is an enlarged sectional view of the movable jaw to be referred to. Fig. 11 is an enlarged detail of the lower portion of the filling parting and uniting devices in a position lntermediate the positions shown in Figs.

6 and '7 just at the instant before the connection of the old and new filling ends is effected. Fig. 12 is a top or plan view of the delivery or eyeend of the shuttle employed in connection with my present invention. Fig. 13 is a perspective diagrammatic view showing the delivery end of the shuttle and the filling-carrier about to be ejected by the in.- sertion of the fresh filling-carrier, the old and new filling ends being shown in heavy full lines and before severance of either. Fig. 14- is a similar view showing the fresh fillingcarrier partly inserted in the shuttle and its filling end severed and carried across the old filling end, such condition closely following the positioning of the parts shown in Fig. (3. Fig. 15 is a view like Fig. 13, but showing the fresh filling end crossed over the old filling end, which latter has been severed, the old filling carrier being completely ejected, the corresponding position of the filling parting and uniting devices being shown in Fig. 11 in readiness to twist the filling ends together; and Fig. 16 is a diagrammatic View taken after the twisting of the ends together and corresponding to the position of the parts illustrated in Fig. '7, the fillingmanipulating means being omitted in all of the diagrammatic figures.

I have shown my invention as applied to a loom wherein a feeler feels the filling in the shuttle at every alternate forward beat of the lay, the feeler operating to effect actuation of the filling-replenishing mechanism prior to complete exhaustion of the filling in the shuttleas, for instance, in United States Patent No. 662,320, dated November 20, 1000, which shows a convenient form of feeler-loom. The breast-beam A lay A filling-feeder F, Figs. 1 and 2, for the filling-supplies or filling-carriers b, the transferrerfi, and the operating or controlling rock-shaft d are and may be all substantially as in said patent. Referring to Fig. 3, the shipper N the feelerf adapted to intermittingly pass through the aperture 3 in the front wall of the shuttle-box B and through a slot at: in the side wall of the shuttle S to feel the filling therein, the devicesintermediate the feeler and the rock-shaft cl to turn the latter in the direction of arrow 20, Fig. 1,when the filling in the shuttle is exhausted to the desired extent, and the filling-fork m and its cooperating parts may be and are all substantially as in said patentand operate as therein described. It is to be understood, however, that my invention is not restricted to feeler mechanism of thisprecise character, as the same per se forms no novel part of this invention.

The transferrer f is mounted to rock on the stud f, rigidly secured to the stand A supporting the filling-feeder F, the stud, however, being extended a considerable distance beyond theouterend of the transferrer-spring S for apurpose to be described. Thedepending end f of the transferrercarries a dog m to be engaged by the bu nter C on the lay when in by suitable holding means, (not shown,) a'

transverse wall s separating the openings from a smaller chamber 5 with which the tu-' bular side-delivery eye communicates. eye may be made in any suitable way-as, for

instance, by a hollow plug 5, screwed into the.

shuttle-body and having an opening 3 into the chamber 5 An upright notch s is made in the wall 8 in alinement with the opening 8 the filling drawing through the notch from the delivery end or tip of the filling-carrier passing through the chamber stand thence into the opening 5' and out at the side of the shuttle through the eye 3; Manifestly the shuttle must be threaded manually, and it is to be noted that in the present embodiment of myinvention breakage of the filling causes stoppage of the loom by or through the detecting action of the filling-fork m in usual. manner. Such breakage is of infrequent occurrence, however, and when it does occur the weaver pieces up the broken filling and then starts the loom; A lateral arm a has at its ends enlargementsa and a Fig. 2, concaved on their inner faces, the enlargement a being adjustably secured to the hubf of the transferrer by a set-screw 6, passed through an elongated slot 7 inthe enlargement and screwed into the hub f the concave face fitting the hub. The arm a eXtends' parallel to the stud f, and on the outer end of the latter is loosely mounted the hub o of a rocking arm 0, the concave face of the enlargement a fitting said hub and being adjustably secured to it by a set-screw S passing through a slot 9 in the enlargement and into the hub. By means of the set-screws 6 and 8 the rocking arm 0 can be set at the requisite angle relative' to the transferrer f, and by reference to Figs. 1 and 2 it will be seen that the said arm extends rearward but outside of the outer disk a of the filling-feeder.

By reference to Figs. 6 and 7 it will be seen that when the transferrer is rocked the arm 0 movesin unison with it, and upon said arm the filling parting, holding, and uniting devices are mounted and are moved into and out of operative position by the rocking movement of said arm.

An arm 6 has its hub e rigidly'secured upon the stud fby a set-screw 10 adjacent the rocking arm 0, inside of the latter, (see Fig. 2,) the fixed arm e being longitudinally recessed on one side at e to receive a prolongation e of a plate 6 a bolt 12 securing the plate to the arm. An overhanging lateral cam-shelf e is formed on the plate fora purpose to be described, and on the same This side of the plate at its rear end an inclined straight groove 6 is made, as best shown in Figs. 6 and 7. The rocking arm 0 has in its side an elongated recess c to receive a 1ongi-' tudinally-adjustable extension 0 provided with a slot 0 through which a bolt 13 passes,

the bolt being supported in the arm a, and by a nut 14 the arm and its extension are rigidly connected- The extension 0 termi-' nates in an upturned flattened head 0 having an upright slot ctsubstantially in aline ment with a long rigid jaw-carrier c depend ing from the head (see Fig. 10) and terminating at its lower end in a jaw 0 preferably provided with a non-metallic facing 15,'of leather, rubber, or other suitable material. A relatively movable cooperating jaw c is provided with a non-metallic facing 16 and is enlarged at its upper end at c and extended forward, the enlargement having a throat 0 Figs. 10 and 10, through which the jawcarrier 0 passes, the lower front edge '42 of the throat being made parallel to the inner face 43 of a stop 0 on the top of the enlarge ment a p By reference to Fig. 10' it willbe seen tha the

faces

42 and 43 normally engage the adjacent sides of the jaw-carrier respectively below and above a pin 17, passed transversely through the movable jaw c at its upper end, V

pansive action of a spiral spring 3, sur-' rounding the jaw-carrier between the under side of the head 0 and the jaw enlargement 0 the latter being extended at the front of the jaw-carrier at 0 for a purpose to be de-'. scribed. The projecting'ends of the pin 17 pass loosely through the lower ends of links 0 connected at their upper ends by a pin 18, adapted to travel in the slot of, the spring .9 tending to hold the pin 18 in the bottom of the slot, and downward movement of the jaw c is then limited by the links, the force of the spring being mainly exerted'at one side of the fulcrum-pin 17 and keeping the jaws open. Upward pressure upon the extension 0 will first rock the jaw 0 011 the fulcrum 17, closing the

faces

15 and 16 upon each other, and thereafter continued pressure will slide the jaw o bodily upward against the. force of the spring .9 the face 16 rubbing over the'opposed face 15 of the jaw '0 while the links o will vlift pin 18in the slot 0 Atrigger g, bifurcated at its lower end,

is fulcrumed at 19 on: the head 0 in' front' When the rocking arm crises to normal posi tion, Fig. l, the cam-shelfe engages a lateral projection g on the trigger, and thereby swings the latter on itsfulcruin 19 against the spring 8 withdrawing the locking-shoulders g from the path of the pin 18, for a purpose made manifest hereinafter. Inside the links 0 two similar bell-cranks h h and 7t shown as made of fiat metal and rigidly connected by

transverse studs

21 and 22, are fulcrumed on the opposite ends of the pin 17 and serve as carriers for the movable blades or cutters which sever the filling ends. One blade 00- operates with a shearing cut with one side of the fixed jaw, and the other blade cooperates in a similar manner with the opposite side of the other jaw, as will be explained.

Referring to Figs. 1, 4, 6, 7, and 11, the cutter-carrier 71. 72 is extended below its fulcrum-at 71 close to the outer side of jaw 0 and it is cut away near its end to present a blade h sharpened on its upper edge and projecting beyond the lower end of a transverse shoulder 71 Referring to Figs 5 and S, the cutter-carrier 7t It has an extension 7: beyond its fulcrum, terminating in a blade 70 sharpened on its lower edge and flattened on its upper edge 70 AS shown in Fig. 9, the inner side of jaw c is slightly inclined and the blade 70 is bent or twisted so that its upper edge will contact with the side of the jaw in one position, and when the cutter-carrier is rocked on its fulcrum, as in Fig. 8, the sharpened edge of the blade will shear over the inner side of the relatively fixed jaw 0 A spring 3" is attached at one end to the outer end of stud 22, and its other end is secured to a pin 23 on the extension 0 the spring acting to rock the upper ends of the cutter-carriers toward the base of the head 0 A guide 0 Figs. 4:, 5, and 10, projects from the head between the arms h and 70 below the stud 22 to assist in guiding the cutter-carriers when rocked, the arms h and 7t thereof moving on opposite sides of the extension 0 The innor end of the stud 22, projecting beyond the arm 70, is adapted to enter the lower end of the groove 8 when the rocking arm 0 rises, and as the latter continues to rise the end of the stud travels to the upper end and out of the groove, and thence along the rear upright edge 50 of the plate e into normal position, (shown in Fig. 1,) at such time holding the cutting-blades h and 70 adjacent opposite sides of the jaw 0 The plate e is prolonged downwardly and rearwardly to form a stop 6 against which the fresh filling end 2? bears between the outer end of the fillingfeeder and the usual thread-holding plate or disk b (partly shown in dotted lines, Fig. 2, and in the diagrammatic figures,) the filling-supply from which such end leads being the one next to be transferred to the shuttle. The replenishing shuttle-box B has its front wall 11 cut away at I) (see Figs. 1,2, 6, and 7) in the downward path of movement of the extension or jaw-closer 0 and the short arms of the cutter-carriers when the lay heats up. A stop I), having its depending web vertically slotted at b, is adjustably secured to the boxwall in the recess b by a clamp-screw b as clearly shown in Figs. 1, 6, and 7, vertical position of the stop being regulated by means of the clamp-screw. The old filling end t leads from the delivery end of the filling-carrier b in the shuttle forward through the slot 5 in the wall 3 and longitudinally across the chamber 5 to the eye 5, and thence out to the cloth, as shown by a heavy full line, Fig. 13, it being supposed that the shuttle is then in the replenishing-box B and that replenishment is about to be effected. The filling end t then extends from the filling-supply b next to be transferred, to the holding-plate b of the filling-feeder, and the other parts of the apparatus are in the normal position. (Shown in Figs. 1 and 2.)

When the filling in the shuttle is exhausted to a predetermined extent, the feeler mechanism causes the rock-shaft d to be turned in the direction of arrow 20, Fig. 1, and the dog m is thereupon moved into the path of the advancing hunter 0 in well-known manner, engagement of said parts rocking the transferrerf and the arm 0 on the stud fas a fulcrum. The descent of the arm a first moves the jaw 0 down and behind the fresh filling end 25 extending above the shuttle, while the cutter h descends in front of it, the shoulder 71, then engaging the filling end and pushing it down off the stop 6 the latter having positioned the filling end therefor. About this time the end of the stud 22 enters and passes down the groove 6 as the arm 0 continues its descent, the groove and spring 8 acting conjointly to rock the cutter-carriers on their fulcrum 17 into the position shown in Fig. (3. Such movement causes the upper edge 70 of the blade k to confine the fresh filling end between it and the inner side of the jaw 0 while the blade or cutter h shears or severs the filling end at the outer side of the jaw and nips the severed end, so that the filling end is held across the face 16 of the jaw. By reference to Fig. 6 it will be seen that then there is a clearance between the jaw c and the blades h and ta to receive the old filling end 25, extending across the chamber .9 and as the lay continues its forward movement the transferrer continues its descent, and the downward movementof arm 0 inserts the jaws into the shuttle-chamber s and brings the short arms 71. and 7c of the cutter-carriers and the jaw-closer against the stop h before the descent of the arm 0 is completed. Their engagement with the stop rocks the jaw c and the cutter-carriers on the pin 17 and nips the old filling end between the opposed faces of the jaws c and c as they close, while the sharp edge of the blade 70 shears across the inner side of jaw c and severs the old filling end 25. Such condition of affairs is shown in Fig. 11 and diagrammatically in Fig. 15, the old filling-carrier having then been ejected and the fresh filling-carrier partly positioned in the shuttle,

ICC

IIO

the final downward movement of the transferrer (shown in Fig. 7) completing the insertion of the fresh filling-carrier, and simultaneously the completion of the downward movement of arm causes the jaw a while in engagement with jaw c to slide upward thereover into the relative position shown in Fig. 7. This sliding movement rubs, rolls, or twists together the two crossed filling ends, firmly uniting them into a continuous thread, as shown in Fig. 16, the jaws when closing and rubbing over each other being within the shuttle-chamber 3 The twisted part or union t Fig. 16, is between the delivery end of the fresh filling-carrier and the eye 5 of the shuttle in the chamber 8 and as the lay begins to move back the transferrer f and the arm 0 begin their rising or return movement, during the first part of which the pressure of the stop 19 upon the cutter-carriers and the jawcloser e is relaxed. Immediately the spring 8 turns the jaw c on its fulcrum away from jaw 0 and the united partt of the filling ends is released, the filling then being free to travel through the shuttle-eye when the shuttle is picked.

It should be noted that when the parts reach the position shown in Fig. 6 at the beginning of the described operation the pin g is freed from the control of the shelf 6 and the trigger-spring s throws the shoulders g across the slot '0 above the pin 18. Then when the final descending movement of the arm 0 causes the relative sliding of the jaws from'the position shown in Fig. 11 to that shown in Fig. '7 the links 0 lift the pin 18, and it wipes past the shoulders 9 and above them, the spring 3 instantly moving the shoulders back beneath the pin, to thereby lock the jaw c in its elevated position relative to the jaw 0? Upon the return of arm 0 to its normal position after the opening of the jaws the cam-shelf e engages the pin g and retracts the trigger g, releasing the pin 18, whereupon the spring 8 expands and slides the jaw 0 down the jaw-carrier (2 into the relative position shown in Figs. 1, 8, and 10. The groove 6 and the edge 50 of the plate 6 act upon the end of the stud 22 and govern the movement of the cutter-carriers to hold and sever the fresh filling end i while the stop I) governs their movement to sever the old filling end if and also effects the closing of the jaws upon the crossed and severed filling ends.

In order to enable the rubbing or relative sliding movement of the jaws to unite or twist together the filling ends, it is necessary that the severed ends be laid across each other, preferably at rather an acute angle, substantially as shown in Fig. 9, and to effect this crossing I have herein provided means to position the fresh filling end as it is severed and held. When the jaws and adjacent devices are moving downward bodily, the shoulder 7L comes down on top of the fresh filling end at the outer side of the jaws and with the filling.

pushes it down at that side, the filling end extending inward in an upwardly-inclined line across the jaw-face 16 to the delivery end of the filling-carrier next to be transferred and which is then in the filling-feeder. The fillin g end occupies this diagonal position across the jaw when severed and held, the inclination being shown at 15 in Fig. 9 and also in Figs lit andwli The position of the old fi1ling end is determined by the position of the tip of the old filling-carrier b in the shuttle and the opening :5 of the delivery-eye s of the shuttle, and as the jaws descend directly into the chamber 5 the old filling end is laid transversely across the jaws, when it is grasped by their closing movement and severed. The

fresh filling end is first grasped and severed, this step being shown-in Big. 14, before ejection of the old filling-carrier from the shuttle, and then the old filling end is grasped and severed (see Eig. 15),j.ust as the old fillingcarrier 1) is ejeqted by the incoming fresh one.

Inasmuch as a continuous filling-thread is provided by my present invention, there are no ends to stick out of the cloth, and the use of a temple thread-cutter and cutting devices on the shuttle-feeler is obviated.

A shuttle-feeler S is shown in Fig. 1, of

usual construction, it acting to prevent the T operation of the replenishing mechanism should the shuttle be improperly positioned in the replenishing shuttle-box, as inautomatic looms of this general type. When the jaws are opened after the union of the filling ends has been effected, the part of the stud 22 between the upper arms 72 and k of the cutter-carriers is held against the rear edge of the head 0 by the spring 3 keeping the blades it and tr pressed forward away from jaw 0' when it opens, so to avoid interference It should be notedthat when the engagement with the stop Z2 closes the jaws upon the crossed filling ends and severs the old filling end by the shearing of the blade la over the inner side of the jaw o the shearing movement of said blade or cutter also withdraws its upper edge it from the jaw 0 thereby releasing the severed fresh filling end. Then when the latter jaw and the cutter-carriers'are moved upward bodily relatively to the jaw c and locked there is nothing to interfere with the release of the united filling ends when the jaws open.

I believe my invention herein disclosed in one practical form is broadly novel and that I am the first to devise means for automatically uniting the end of a fresh supply of filling to the filling in the running shuttle to form a practically-continuous filling-thread, and accordingly my invention is not in any sense restricted to the construction and ar rangement herein shown and described, for the same is merely one practical embodiment thereof, and various changes, modifications, or rearrangements of parts may be made by those skilled in the art without departing from I Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
