(Cl. 139-255) ‘ 1 This invention relates to improvements in bob bin receivers for weft replenishing looms and it is the general object of the invention to provide a receiver which is reversible or can be turned inside out to discharge bobbins therefrom. In weft replenishing operations the spent or exhausted bobbins are discharged downwardly " the direction of arrow 4, Fig. '1, and showing the parts in normal position, j I Fig. '5 is a, View similar to Fig‘. 4 but showing the parts in discharge position, ' Fig. 6 is a view similar to a part of Fig. 1, but, > showing the receiver in discharging position pre paratory to emptying the bobbins therefrom, ' ' Figs. 'Zand 8 are diagrammatic views showing. successive steps in turning the bag inside out‘ for the purpose of. discharging the bobbins'there when‘ the bobbins are tobedischarged therefrom. 10 It is an important object of the present inven Fig. 9 is a front elevationlooking in the direc from the shuttle and are ordinarily collected in a can or the like which must be lifted'and inverted from, and ‘ I I . tion to provide a bobbin receiver including a tion of arrow 9, Fig. 4.

In the accompanying drawing, wherein a con venient embodimentv of my invention is set forth, Fig. 1 is a side elevation of part of a loom showing the invention in normal position, parts of the loom beingin section, " _ Fig- 2 is a plan view'of the receiver looking in the direction of arrow 2, Fig. 1, ' I Fig. 3 is a vertical section on line 3-.—3 of Fig. 2, -' Fig‘. 4 is an enlarged detailed plan looking-in , 2D and then horizontallytoward thegloom frame ' toprovide a journal, 21., 'IllheIIjournalv extends into and is rotatable and slidablejin‘a bearing hub 22, on the support A, the latter being‘ fase tened. to the loom frame as at 23. The axis of the hub is horizontal and preferably parallel to ‘ the lay. ,. I The hub 22‘has extending laterallyfrom the forward part thereof a stop lug 25 provided with a rearwardly facing vertical groove .26 propor 2,411,947 3 tioned to receive the stop arm 20. A second lug 27 projects from bearing 22 beyond and below 4 away from the lay. The cords 38 are now pulled upwardly through the mouth the effect of which is to lift the back part of the bag and crowd the lug 25 and spaced from the latter to form a notch 28. The notch receives stop arm 20 and lug 21 bobbins forwardly, after which continued pulling supports it when bobbins are being discharged 5 on the cords will eventually turn the bag inside from the receiver. The journal 2| extends be yond the inner end of bearing hub 22 and has secured thereto a collar 30 which will be spaced from the bearing 22 when the stop arm 2c is in the notch or recess 26. out. During this operation the bag passes through the successive positions shown in Figs. 6, 7 and 8. When in the position in Fig. 8 the bobbins will fall into a receiver 45 which is moved from The collar 30 is so 10 loom to 100m by the attendant. located that the journal 2| can slide along the bearing 22 in a direction away from the loom side su?iciently to enable the stop arm or mem ber 20 to clear the upper part of the lug 25 but not far enough to move beyond the lower stop lug 21. The bag B may be made ofany sufficiently ?exible and wear resisting material and has its After the bag is emptied the attendant returns it to its normal position, pushing the bag back. through the frame F and slackening the cords 38. The frame F is then moved outwardly to dis engage stop arm 20 from notch 28 and is then raised by an angular movement which is clockwise as viewed in Fig. 1; until the stop arm 20 is slight ly behind the stop lug 25. after which the re upper edges attached in any approved manner ceiver is moved a short distance toward the loom to the members l5—l8 of the frame F. The in 20 frame so that the stop arm 20 can enter notch terior of the bag will have secured thereto two 26. The receiver is now reset and will remain sets of guide means such as eyelets, one of these in a. stable position due to its weight as already sets being preferably adjacent to that part of described. the bag which depends from the inner side mem When the bag is being turned inside out the ber l8 and the other set being on the opposite 25 upward pull on cords 38 may tend to raise frame side of the bag which depends from the member F. This motion will be prevented by engagement [6. Each set of guides will have a forward eye of stop arm 20 with the underside of lug 25. let 35, a lower rear eyelet 36, and an upper rear t may not be necessary in all instances to use eyelet 31. A lifting cord or strap 38 is provided the notch 28, since the attendant can hold frame for each set of eyelets, and each cord is fastened 30 F down with one hand while pulling on cords 38 to its corresponding forward eyelet 35 and then with the other hand. is trained through its eyelets 36 and 31 and ex The hooks 40 shown for the upper ends of the tends upwardly to the forward part ofthe mouth cords 38 are not essential, since the cords can of the bag and may have a hook 40 thereon to fall into the bag and the attendant can lift them be held by the front member I‘! of the frame F. 35 from under the accumulated bobbins preparatory I ?nd it is preferable to have the upper rear eye to emptying the bag.
