Application November 21, 1946, Serial No. 711,389

A 8' Claims. =l This invention relatesto a" loom .and ,more Yparticularly to a control forstopping'the loom. 'Itis usual vin the operation of haloorn which lis auto- K4rnatically causedto'stop 'when the lling 'fails that the 'shuttle will come to rest at the transfer 'end-of "the lay rather than atth'e end of "thelay vwhere the shipper llever with 'its handle is located. When the shuttleofa loom comes to rest at the Iend of the lay remote 4from 'thatfend'at which the shipper handle is located,itibecomesnecessary 'for the loom operator to turn over the crank shaft Yloy hand and move the shuttle rfrom the transfer end of 'the lay Ito the vshipper handle end ofthe lay Vto piece up 'the rfilling. A loom operator who ldoesfturn over nthe crank shaft "for vthis purpose lusually 'getsh-is handsdirty and the `woven fabric or thread will in 'many instances 4thus become soiled from the v4operators lfhands, `besides sometime i-s lconsumed inthe turning over the loom for such lpiecing up.

One -of the 'objects'of `this invention lis jto "so delay the movement of the shipper handle in Vvits -travel v`from operating position 'to inoperating "position `that-.the shuttle Awill takefone more pick and will cornefto rest 1at the shipper handle enol -of the lay.

:Another-object -of 'this 'invention "is -to provide .a veryzsimple attachmentto the alreadyexlsting loom `-vvliic'h may l'be simply assembled thereon '-to .cause ythel desired action.

.A more kspecificobject of 'this 'invention -isfto 'l -fprovide a hook which @will ycatch the shipper -handle whensrelease'd from its operating position( ato retainltheshipper handleuritil'thefllling motion has 'returned from aposition which causes .release .of .theshipper hand-1e.

With'` these :and-other'zobjects in views` thei'nven- .tion consists of .certain novel fea'tures of con- :structionsas Vwill ibezfmore rfully .describedran'd particularly Ypointed Vzout in fthe A#appended claims.

Fig. asectional view .showing the shipper lever and ...spring fonmovingit to one fend for the .slot .in which .it operates.

In .proceeding Awith this invention, I attach a catch on the :release Vor shipper motion lever which pushes theshipp'er "handle or lever from its voperating"position into a *position to 'stop the loom, whlchfcatc'h'will engagethe shipper lever and hold it 'fromtinoving .to inoperative position, and I also :provide a spring which, after the filling fork slide has returned from Aactuating positionywill cause the release lever to release the shipper lever by retracting "thehook from engagement therewith. This retarding 0f the stopping of the loom will be so-tirn'ed as to cause the shuttle vto :moveto the 'shipper hand-le `end of the lay, making "it unnecessary to "turn over the crank shaft 'by hand and manually move the shuttle across -the lay.

With reference tothe drawings, l0 designates a part of the framework l'oftheloorn and I-l vthe cam shaft having va cam I4 thereon which-'engages the cam follower I5 secured at the end of the-cam follower lever |56 which 'is `pivoted as at l1 (see Fig. 3) and has afollower dog lsecured on the other side of its pivot which vos'cillates'each time the cam shaft rotates. This ydog -has'th'e camffollower trip I9 secured thereon as well as a filling motion hook 20. The filling forkZ'l is mounted in its holder 22 'and pivote'd as -at 2-3 and 'has a latch 24 to 'engage the catch 25 of 'the filling Inotion hook 20 in case the lling 2B, which Ais shown as spaced from the lay (Fig. 1) designated generally 21, fails or is not prescritto swing the trip 2| out of the way. 'The 'filling fork slide designated 'generally Y21has *mounted on it the Vlll'lng motion trip 28, and this slide willmove forwardly on the lling motion stand 29 so that fthe trip '23 will engage the filling motion finger 30 on the end of the shipper rirno'tion lever 31, 'which is pivoted as at 38,'to swing the arm 39 of the release lever 31 into engagement with theshipp'er lever 40 "having 'a handle y35 vat the upper 'end 'thereof A(See Fig. 4).

. This 'shipper leverl's 'shown -as located in the slot 4| in the shipper f1ock42 4which/has `an oiset or notch `43 along one Wall 44 of the slot 4l so as to .provide a Yshoulder 45 with which the lever 31 which contacts the shipper lever 40. This hook is provided with an abutment surface l to engage the edge 52 of the shipper lever 4G and hold the same while in engagement therewith. This surface 5l is so positioned on the arm 39 that, when the shipper lever is in operating position, the surface will be spaced from the shoulder 45 in the direction of the inoperative end 46 of the slot 4l.

When the conditions are such that the lever 3l will be swung clockwise around its pivot 38 by movement of the filling fork slide, the end of the arm 39 will push the shipper lever out of the notch 43 and beyond the shoulder 45. The shipper lever will then start to move toward the inoperative end 46 of the slot 4i by a constantly acting tension spring 36 usual in mechanisms of this character with the shipper lever sliding along the Wall 44 of the slot. However, before the shipper lever has moved any substantial amount, the surface 5l of the catch 5G will engage the shipper lever and arrest its movement, Thus, the shipper lever does not move far enough to canse stopping of the loom, and the shuttle 55 which has travelled to the transfer end of the loom will be returned by the picker stick at the transfer end of the loom into the shuttle box 5E as shown in Fig. 1, However, the spring 5l', as shown in Figs. .1 and 2, is

acting upon the filling fork slide to return the slide; and after the slide is returned, the spring 41, acting upon the releasing lever 31, will swing this lever counter-clockwise to Withdraw the catch or hook 50 from the shipper lever 40, which being .against the wall 44, as shown in Fig. 2, is then free to be moved by its spring along the Wall 44 to the inoperative -end 46 of the slot 4! and the loom will be stopped.

By this arrangement, the delay in the movement ofthe shipper handle to an inoperative position Yby catching the same and holding the same until the lling fork slide has returned permits just suicient time for the picker stick at the opposite end of the loom to operate and cause the shuttle to be returned to the end of the loom where the shipper lever is located.

It will be apparent that the shipper lever is provided with the usual handle for operation which extends upwardly and is enlarged somewhat from the lever portion thereof which is out olf in the showing in the drawing so as not to hide the edge of the lever which catches on the abutment and the action with hook 59 which would otherwise be hidden.
