EDWARD S. STIMPSON, OF I-lOlPEIDALE7 MASSACHUSETTS, .ASSIGNOR TO DRAPER COMPANY, OF I-IOIPllll'JALE, MASSACHUSETTS, A CORPORATION OF MAINE.

Application led August G, 1914.

To all whom t may concern Be it known that l, EDWARD S. SriMrsoN, a citizen of the United States, residing at Hopedale, county of lVol-cester, and State of Massachusetts, have invented an Improvement in Filling-End Controllers for Looms, of which the following` description, in connection withthe accompanying drawings, is a specification, like letters on the drawings representing like parts.

The invention to be hereinafter described relates to looms of the filling replenishing type, wherein the supply of iilling is replenished prior to complete exhaustion, and more particularly it has reference to means for controlling the end of the filling on the carrier to be abandoned in order that it may not be carried into the shed. In looms 0f this general type, when replenishment is called by any well understood feeler mechanism, and either the shuttle or carrier in' the shuttle is changed for another having a working supply, there extends from the cloth selvage to the shuttle at the replenishing side of the loom, a length of filling which, when the shuttle or carrier is ejected, is liable to be carried into the shed and produce imperfect cloth. Various attempts have been made heretofore to dispose of this length of filling. Some of these have had combined clamps and cutters which, upon call for filling replenishment, would move toward the lay or rearward of the loom, cut the filling between the selvage and shuttle, hold the end leading from the selvage, and move it forward or toward the breast beam into such position that it could be cut by the usual temple thread cutter adjacent the cloth selvage. In these cases, however, the clamping and cutting means would continue to hold the filling end until the next call for filling replenishment, whereupon, said means would be moved toward the lay while still holding the now detached piece of filling. and would release such piece only as said means was moved to grasp another filling end with the result that the old piece of filling was still liable to be carried into the shed when released by the clamping and cutting means. ln other cases, devices in addition to the clamping and slitting means have been employed to vengage the filling endy when carried forward by the said means, but such devices introduce complications which are not always certain of eiiicient action, so that Specification of Letters Patent.

serial No. 855,506.

as the clamping and cutting means has started in response to the call for filling replenishment, the old lilling end would go with said means with the undesirable result stated.

lith these matters in mind, one of the important features of the present invention is to provide means for severing` or parting the filling between the selvage and the carrier to be abandoned, and carrying the end leading from the selvage into a position at the front of the loom so far remote from'the lay that danger of its being caught and carried into the shed is avoided, and then releasing the loose end of filling so that when thus released it willbe outside the danger zone of the lay and other parts which might otherwise cause the end to be carried into the shed. A further feature of importance is that when moved toward the front of the lay, the filling end is not released until a plurality of picks, so that time is afforded for the action of the selvage thread or temple cutter.

Various features of the invention, as for instance the delay in filling end release at front position for a predetermined number of picks, the characteristics of the release, and others will best be made clear from the following description and accompanying drawings of one form of means for carrying the invention into practical effect, it being understood that the invention is not restricted to the described details, but is definitely defined by the claims.

In the drawings Figure l is a transverse section of a portion of an automatic filling' replenishing loom having one form or embodiment of the present invention applied thereto, the lay being shown in back position by full lines and at front position by dotted lines, and only such other parts being illustrated as are necessary for a proper understanding` of the invention; Fig. 2 is a detached detail on an enlarged scale, showing one form of means for releasing the filling end after a plurality of picks following filling replenishment; Fig. 3 is a like view of the same parts in a different position; Fig. i is a plan view showing the association and relation ofthe parts of Fig. 2; and lFig. 5 is a detail of the filling cutter and clamp showing the guiding means therefor and the cutter and clamp in retracted or front position in full lines, and two other positions in dotted lines.

The present invention is herein shown aS associated with the clamp and cutter fully described in the patent to Harry A. Davis, No. 1,091,813, dated March 31, 1914, and reference may be had thereto for a detailed explanation of the construction and operation of such parts. As set forth in said patent, the filling or thread clamping and parting means, usually carried by and moving with the shuttle feeler, seize the filling of the carrier to be abandoned, sever it near the shuttle, clamp the end and carry it for ward so as to bring the filling into the field of action of the usual temple thread cutter, which thereupon severs the end of the filling close-to the cloth selvage, the said clamping and parting being called into action only upon the actual transference of a filling carrier from the source of supply to the shuttle. In said patented structure, however, the clamping and parting means retained their hold of the filling after it was cut or severed at the selvage, and released it only when the said means was again called into action to grasp and sever another filling end, whereupon said means would carry the now loose end of filling toward the lay and release it where it was liable to be carried into the shed. In the present form of the invention, it is shown as associated with the clamping and severing means of said patent, but instead of holding the loose end of filling until the clamping and parting means is again called into action by the filling replenishment operation, means are provided to cause the clamping and parting means to release the loose end of filling prior to the call for replenishment and in a position well forward of the lav or near the front of the loom, so that all danger of carrying the end into the shed is eliminated. It will be understood, of course, that the invention is not restricted to use in connection with the particular clamping and parting means of said patent, because in its generic sense it may be employed in various other relation, but this present association will serve to make clear the characterizing features thereof.

The lay A3; the transferrer f constituting a part of the replenishing mechanism for transferring a bobbin Z1* from the filling mechanism or hopper F to the shuttle S when in the box at the replenishing side of the loom; the controlling rock shaft d and its adjuncts; the shuttle feeler 9; the fixed and movable plates 16 and 17 carried by the feeler and the plate 19 constituting the fixed member of the thread clamp; the usual guide stop it against which the filling carrier or bobbin bx is brought in position for transfer; the yielding bobbin support consisting o-f the finger 20 on the swinging plate 21 provided with the hub 22, said linger being located adjacent the inner face of the disk of the hopper and opposite the stop t;

'K the finger 23; the stand F2; the spring 25;

the striker arm 31 for operating the movable member' 17 to clamp and part the filling; the arm 12; the spring Sx the bell crank lever 53 having the arms 60 and 65; the connecting link 66 pivoted at its lower end to the arm (12 and at its upper end provided with the slot 67 fitting over a stud 68 on the arm 05; the arm 44 and connections; the sleeve 49 constituting the feeler support and mounted to slide upon the guide bar 48; the supporting arm extending from the sleeve 49 and carrying the shuttle feeler and the members of the thread clamp and parter; and the connections between the arm and the sleeve 49 for giving its reciprocating motion on the guide rod 48; may all be substantially the same asin the' said prior patent, and since the said parts are fully described and shown therein, further elucidation thereof here will be unnecessary.

In operation of the parts thus briefly referred to, and described in said prior patent, when the replenishment of the filling is called for, the shuttle feeler support 49 is moved rearward or toward the lay rectilinearly on the guide bar 48 until it is stopped by the pin 90 and the feeler together with the members of the clamp and parter will be moved to rear position, so that if the shuttle is properly boxed the clamp and parter will be operated to sever the filling on the shuttle side thereof, and hold the end leading from the selvage. 0n frontward movement, as pointed out in said patent, the clamp and parter will carry the end of the filling toward the front of the loom and hold it for the action of the temple thread cutter, and then will continue to hold the loose end of the filling` until the next call for replenishment, whereupon the clamp and parter will again be moved toward the lay or rearward, and then, while in such position, will be opened to release the loose filling end according to the construction shown and Adescribed in said patent. To overcome liability of the loose end being carried into the shed, the present invention contemplates means, when applied to the clamp and parter of said patent, to open said clamp and parter prior to the next call for filling replenishment and while the said clamp and parter are in a position remote from the lay and toward the front of the loom, as will now be described.

Adjustably mounted on a suitable part of the loom frame, preferably the breast beam, is a stand 100 in which is slidingly mounted a slide 1.01 carrying at its rear end, (that toward the lay), a contact foot or arm 102 which is preferably mounted adjustably on the slide 101 by bolts 103 and slots 104 as clearly indicated in Figs. 1 and 4` Normally tending to hold the slide 101 in extended position toward the lay, is a spring 105, one end of which bears upon the collar 106 secured to the slide 101, and the other end of which finds a seat against the end portion 107 of the stand 100, the construction being such that the slide 101 is normally held in the position indicated in Fig. 4, but is permitted to yield frontward or toward the breastbeam by contact of the lay or part carried thereby with the contact foot 102.

Rising from the stand 100 is a lug or extension 108, Figs. 1 and 4, to which is pivoted at 109 a toothed cam 110. The toothed cam 110, Fig. 2, carries a series of teeth 111, Figs. 2 and 3, concentric to the pivot 109 and a second set of teeth 112 eccentric there` to, as indicated in Fig. 2.

Secured to the arm 60 of the bell crank 53, Fig. 1, and preferably adjustable thereon, is a controller 113, which, acts upon the eccentrically-arranged teeth 112 on the toothed cam 110 for controlling the position of the arm 60 and, perforce, the move-- ments of the sleeve 49, as will more fully appear. Preferably the controller 113 is connected to the arm 60 by means of a slot and bolt connection 114, as indicated in Fig. 1, whereby the position of theV controller may be altered to conform to conditions of use.

Mounted on the pivot stud 109 connecting the toothed cam 110 to thelug 108 is a spring 115, Fig. 4, one end of which is connected to the toothed cam 110 as at 116, Fig. 4, and the other end to the lug 10S, the construction being such that the tendency of the spring is to turn the toothed cam 110 from the position indicated in Fig. 3 to that of Fig. 2 when said spring is free to act.

Connected with the slide 101 is a pawl actuating arm 117, Figs. 2 and 4, having pivoted thereon at 118 a pawl 119 normally under the action of a spring 120 tending to raise the active end of the pawl into position to engage the concentrically-arranged teeth 111 on the toothed cam 110, the other end 120X of said pawl being adapted to engage a lined cam 121 on the stand 100, when said arm 117 is moved into the full line position toward the lay, as indicated in Fig. 2.

FVhen the parts are in normal position and prior to the call for filling replenishment, they are as indicated in Fig. 1, with the controller 113 bearing upon the curved upper surface 122 of the toothed cam 110. lVhen, however, filling replenishment is called, the arm 60, through` its connection with the rock shaft cl, is moved to carry the sleeve 49, and the thread clamp and parter into rearward position, or toward the lav, the controller 113 leaves the surface 122 of the toothed cam 110, whereupon said cam under the action of its spring 115 is at once turned from the position indicated in Figs. 1 and 3, to that of Fig. 2, so that after filling replenishment, when the arm 60 returns toward the front .of the loom under the action of' the spring SX, the controller 113 engages the toothed cam 110 at a point 123 nearer to the axis 109 of the toothed cam than is the part 124 of the series of eccentric teeth 112. As the lay beats up following filling replenishment, it meets the foot 102 of the slide 101 and moves said slide toward the front of the loom, whereupon the active end of the pawl 119 engages a tooth of the series 111 and turns the toothed cam the distance of one tooth., the controller 113 at such time riding up the rst tooth of the eccentric series 112 and holding the toothed cam in the new position. On each subsequent forward movement of the lay this action is repeated, the controller 113 riding successively over the eccentric teeth 112 and forcing the arm 60 rearwardly or toward the lay until, when the controller rides over the last tooth 124 of the toothed cam 110, the spring SX causes the controller to engage the curved surface 122 of the toothed cam as indicated in Fig. 3, and the parts assume the position indicated in Fig. 1. As the arm 60, after `filling replenishment, is moved by the eccentric portion of the toothed cam 110, step-by-step rearward or toward the lay, the sleeve 49 and, perforce the thread clamp and parter, are correspondingly moved, such movement being less than the movement of said arm 00 under the call for filling replenishment. This auxiliary or less movement of the arm 60 is utilized in the present form of the invention to cause the thread clamp and parter to release the thread, such release taking place after a plurality of picks determined by the number of teeth on the toothed cam. To effect this release in the present form of the invention, the guide 48 has secured thereto, a catch 125, Fig. 5, which may be of suitable character, and as shown, is in the form of a leaf spring 120 having an appropriate head, and secured at one end in a recess 127 on the guide 48, the construction being such that as the thread clamp and parter move from their rear' position to the front position after filling replenishment as hereinbefore described, the said clamp and parter will remain closed, the tail end 92 thereof passing into the full line position as indicated in Fig. 5. The thread clamp and parter being in this position, and the toothed cam being in the position indicated in Fig. 2, as the lay beats up the successive picks, the toothed cam through the controller 113 moves the arm 60 step-by-step toward the lay, thereby advancing the thread clamp and parteil from the position indicated in full lines, Fig. 5, to the intermediate position indicated by dotted lines, Fig. 5, al which time the part 92 engages the catch 125 and opens the thread clamp and parter at or about the time the controller 113 passes series.

leading from the selvage.

trom-the last tooth 121 of the eccentric As the controller 113 passes from the last tooth 124 of the eccentric series 112, it assumes the dotted line position of Fig. 3, and under the action of the spring SX, the controller moves along the curved surface 122 lcarrying the arm 60, and pertorce, the thread clamp and parter to its inner position. The action of the controller along the curved surface 122 of the toothed cam 110 is utilized in the present form of the invention to remove the foot 102 from the position where it would be met by the lay or a projection thereon as will now be explained.

rlhe arm 117 of the slide 101 is provided with a shoulder 12S, Figs. 2 and 3, which is adapted to be engaged by the end of a holder 129 pivoted at 130 to the toothed cam 110, the construction being such that as the toothed cam 110 is turned step-by-step in the manner hereinbetore described, the holder 129 is drawn toward the front of the loom, Fig. 1, and by engagement of its end with the shoulder 12S, moves the toot 102 forward a sufficient distance as indicated by dotted lines 131, Fig. 2, to prevent contact therewith by the lay. Engagement of the holder 129 with the shoulder 12S occurs at or about the time the controller 113 is in dotted line position, Fig. 3; and the torce of the spring SX acting through the arm 60 to move the controller along the curved surface 122 of the toothed cam, gives a -further rotative limpulse to the full line position indicated in Fig. 3, thereby eiiecting the desired movement of the foot 102 into inoperative position.

It is desirable that the holder 129 tree the slide 110 to the action of its spring 105, and permit it to move into operative or full line position, Fig. 2, when the toothed cam 110 is turned by its spring 115 from its normal. position, Fig. 3, into the position in Fig. 2, on the call for filling replenishment, and to this end there is provided on the stand 100, a projection 132, Figs. 2 and 3, over which rides an incline 133 on the holder 12. as the toothed cam turns contra-clockwise, viewing the parts indicated in Fi 3, thereby raising the end of the holder' 129 and 'freeing the slide.

From the construction described, .it will be seen that as the thread clamp and parter move to rear position, or toward the lay on the call for iilling replenishment, the members thereof will be opened or separated and thereafter closed by the part 31 to sever and clamp the end oit the severed thread The parts will then return to front position with the clamp and parter still closed upon the end of the thread. Thereupon the thread clamp and parter will be moved step-by-step at each forward movement of the lay to advance said clamp and parter for the opening action thereof by the catch 125, thereby releasing the thread While substantially at the front of the loom, whereupon the parts resume normal position as indicated in Fig. 1.

It is desirable, of course, after carrying the end of the severed thread toward the front oitl the loom, to hold it for a sutlicient length oit time in position for the thread to be severed or cut by the thread cutter adjacent the cloth selvage; and this desirable characteristic is attained bythe formation of the toothed cam 110, with the teeth thereon in a series determining the number ot picks or the length of time that shall elapse before the end of the thread is released by the clamp and parter.

lit may sometimes be desirable to limit the movement of the toothed cam under the action of its spring 115 without depending upon the controller 113 to stop the cam in position indicated in Fig. 2, and to insure this relation of parts, the toothed cam may be provided with a stop 13-/1 adapted to engage an abutment 135, Fig. 2, projecting trom the stand 100, but these are not always essential.

lli/Then applied to the particular form of clamp and parter herein described, the form of means for effecting the release of the tilling end at the front of the loom has been found to be practically etlicient; but of course it is to be understood that details of such means may be varied without departing from the true scope of the invention as de fined by the claims; and it will be apparent also, that the invention may be variously applied to discharge its functional characten istic of parting and clamping the lilling end between the selvage and shuttle, carrying the filling end toward the front of the loom and into position to be engaged by the teinple or other cutter at the cloth selvage, and there release it While at the front of the loom.
