Serial No. 482,995.

This invention relatesto filling replenishing looms wherein the illingis changed from V'time to time either by thesubstitution of a fresh shuttle for that which has become depleted or by a change of the filling carrier in the shuttle for a freshV filling carrier.

Infilling replenishing looms it is desirable thattheoutgoing and incoming iillingend be parted at ther replenishing side of the loom and that incase the filling fails at this point the lloom be stopped.

Y Y Heretofore it has been common to provide .f filling or weft fork mechanisms to stop the loom in case of filling failure, and also to cut or part the incoming and outgoing filling Yends.V In looms for weft pile fabrics, however, where the ends of the pile wires extend `beyond the edge or selvage of the Cloth and are "accumulated in this position for a number of picks, the Vproblem ofv effecting'the foregoing desirable'results becomes complicated,fand-one of the objects of the present invention is to provide means forefecting loom stoppage through the filling fork when filling-failsto be laid in theshed and to cut orpart the filling vends at the side of the yloom yadjacent the replenishing mechanism; 7

More specifically stated, the weft fork actuating slide and thelcutting or parting mechanism are each actuated bya novel train of devicesdisposed at the,filling-replenishing t side of lthe loom and adapted to be operated through or by the lay movements.

The invention and novel features thereof `will .best be maderclear from the following description and the accompanying drawings of one good form thereof,

In the drawings: i K' VIligl is a perspective view of parts of a shuttle replenishing loom provided with the features of the present invention Fig.f2 is a vertical sectional view through they filling fork mechanism;

I Fig. Sis a top'pla'n view of parts in Fig.'2; f f I' shown Fig. 4 is a View similar to Fig. 2 but shows i Fig. 5 is a sectional view taken on the line 5 5 of Fig. 4.

The features of the present invention have been lllustrated in connection with a pile vfabric loom provided with shuttle transfer `mechanism similar to that more fully shown and described in the Edwin W. Stone application, SerialNo. 481,841 filed Sept..15, 1930. The loom shown has the breast beam or supporting structure l in front of whichV isV disposed the usual take-up roll 2 about which the woven fabric F is advanced during the weaving operation, in a well-known manner.

The loom is also provided with the usual lay 3 supported by the lay swords 4 for move#` ment towards and from the frontof the loom and the lay is provided with the reed 5 which is supported at its upper end by the reed cap 6, the opposite ends of this reed cap being `secured to the extensions 7 provided at thel upper ends of the lay swords.v

At theleft-hand side of thel'loom illustrated'in Fig. 1 is provided 'the shuttle replenishing mechanism comprising the shuttle magazine 8 which is adjustably supported... Vby the bracket 9 secured to the loom frame.

` Thel shuttle box at the rear of the shuttle maga-zine 8 is shown as having a movable front wallv 10 adapted to be carried upwardly by the supporting arms 11 in a manner la pile fabric and is shown as provided with pilewires 13, the forward ends of which are `shown in Fig. 3 as extending some distance rfrom the selvage at the left-hand side of the the lay of the loom of Fig. 1, looking towards abrlc The vfeatures so far described form no essential part of the present invention but have beenk illustrated and briefly set forth to makeV clear the construction and location -of the filling fork and shear mechanism to be described, and the novel mechanism of the ,present invention for imparting a detecting movement to the slide operating lever kand for operating the shear blade. The filling fork mechanism illustrated comprises a trough-shaped stand 14 which is rigidly se-V cured to the breast beam or main frame of the loom in position tofclear-.theends- 1 3 of the lpile wires; as shown,.land :in'thisgstand is slidably mounted the iilling forlr slide 15.z

In accordance with the present invention, 1the-means for moving the filling forkV slide 'frontwardly Awhen an absence fof filling is vdetected comprises a slide operating lever '28, the lower end of which is pivotally sup- `portedibythefpin'29 carried by the bracket or housing B0-secured to the loom-frame,v and the lever-528 is continuously-urgedtowards the dotted line position of Fig. 2 by the coiled spring 31.v The lever 28 is shown as having ahead or 'enlargement at its Aupper endy and this head [is provided iwith Va .shoulder 32 adapted togengage the .looped `portieri 18 .of .the fillingjfork whenthelatter remains .the lowered position of. l`|`i g.s4, .upon adete'cting beat ofthe .lever.-28.

The actu at` -gvcam 39 isadaptedto bef-en-v gaged-,each time thelaybeatsup bya plunger 42lcarriedby the lafyQ` This ,plungerinjthe "construction shown is pivotal-'ly Avsecured at 43 to the bracket 44 on the lay, andtheplunger 442 is normally vheld in jtliefhovriiz'ontal `positi'onjin which it is shownin .lfbyspringsr 45 mounted on thero'd '46.supported by the ears 47. Therod 46'eXtends'through ahole 48 `inthe`plu-nger42. The arrangement is such that'theLplunger .42- may be ro'clred in either an upwar'd'or 'aidownward direction from its @normally horizolitalposition vbut as soon as theplimgeris releasedv itwillfberepanding-actiono-f'the springs45.; v

As aV Yresult of? the :construction: just ideturnedto itsfhorizontalfposition;by .the eX- llle present-invention departsfromthese,y Y

prior formsfofoperating meansbysernplfyf yinactive position during one beat-up movement of the lay but is moved frontwardly upon the next beat-up movement of the lay and remains in this frontward position until the operating cam 37 is again rocked in a downward direction so that the lever 28 may ret-urn to its rearward position under the. ac-

tion of the spring 31.

It will be seen from the foregoing that the plunger 42 operates the cams 37 and 39 so that they will impart a detecting beat to the lever 28 only upon every other frontward movementof the lay, and as a result the filling fork slide will be forced frontwardly only Awhen thefshuttle is in the left-hand box, viewing Fig. 1, and the filling fails to tilt the filling yfork sufficiently to clear the shoulder 32 of the slide operating lever.

Itis apparent that when filling replenishment is effected, a trailing end of filling will 'be formed extending from the cloth selvage.

In the construction shown,itwo of these trailing ends are formed, one by the ejected exhausted shuttle and the other by the new shuttle. It is desirable to part these trailing ends so that they will not be carried into the 'n shed, and shearing means to this end may comprise a fixed shear blade 49 rigidly secured to the stand 14 and a movable shear blade 50 supported by the pivotal pin 51, and the movable blade 50 is preferably yieldingly held against the fixed blade by the coiled spring 52 provided upon the pin 51 between the movable blade and nuts 53.

The movable shear blade 50 is actuated in accordance with the present invention from the rocking shaft 38, and to this end the shaft 38 is provided with an actuating arm 54 which is operatively connected to the rear` end portion of the blade 50 by the connecting link 55. The arrangement is such that one beatup movement of the lay will rock the shaft 38 in a direction to open the shear blade 50 and the. next beat-up movement of the lay will close this shear blade to clip the trailing filling, provided the same has been advanced frontwardly by the fabric F between the blades 49 and 50.

The coiled spring 52 serves to create sufficient friction between the cooperating blades 49 and 50 to cause the blade 5() to remain in either its open or closed position until it is positively shifted from such position by the ytion'the forward movement of the lay is utilplunger 42 upon the. next forward-movement of the lay.

f It will be seen from the foregoing that through the mechanism of the present invenized to operate both the slide operating lever and filling shearing mechanism, and that the mechanism for operating these elements is simple in construction and reliable in operation.
