The present invention relates to :bobbin receptacles for loomsand as illustrated herein, relates more particularly to supports for such receptacles which permit 1 the receptacle to be easily moved out of bobbin receiving position'an'dwhich movethe receptacle-automatically into bobbin 3 receiving position relatively to the shuttle-box of theloom.

:Receptaclesare. provided, in automatic looms,

- to receive and collect empty "filling carriers '01 bobbins as they are ejected fromtheushuttlecby an incoming filled bobbin orifillingrcarrier. iThe receptacles areusually positioned below the shuttle. box of the loom toreceive the emptylbobbins and are usually so-positione'd that the.passageficult to'reach into the receptacles-to remove the empty bobbins when' the receptacles are-in-bobbin receiving position. In priorldevices, provision has been made to swing or move the receptacles out of their normalapositions to. facilitate mal bobbin receiving-positions. 'Thisis objectionable-since the receptaolesrmay remain in: the passageway and i-nterfere withother-necessary operations.

--An object of the present invention, accordingly, is to provide means for supporting abobbin receptacle wherein the-abovementioned.difiiculties "willbeovercome. Tothis end the invention. contemplates=a support for the receptacle wherein the bobbin receptacle automatically returns to -bobbin receiving position after. havingbeen dis- "placed therefrom either intentionally or accident- "ly. Thus danger'of injury either to the- -receptable or to the' contents thereof is effectively vented.

pre

Another 'object'of the invention is to improve "generally upon the constructionofbobbin receptables and supports therefor.

With the above and other objects and'features in view, the invention will nowbe described" with V particular reference to the accompanyingdraw- "ings inwhich:

To this end the=-sidewalls2 l 'areoeabheprovided with a convex projection 1'23. The worwardedge of each "sidewall I ,"therefore, Y is longer Ithan the "vertical length of the'sidewall. 'The forward wall l 9 hasa lengthequal' tothe lengthofi the'forward edge of the sidewall 2|.

A receptacle so constructed will contain a large number of bobbins due in part, at least, to the fact that the receptacle conforms somewhat to the bobbins and thus permits the bobbins to pack or rest more closely. The receptacle I is provided at its upper end with an 5 interrupted hem 22, the hem being formed by turning theimaterial of the bag on itself and securin the hem in position by stitching or cement. The hem 22 is interrupted at two places to permit a supporting frame to be inserted in 10.

bent substantially U-shaped with one leg of the.

U somewhat longer than the otheras shown best in Fig. 4. The rod 28 is also bent into a U-shape but the inner rear bend or corner 30 is bent at an acute angle to permit the mouth of the receptacle III to extend well under the bobbin guide 32 when the lay I4 is in its extreme forward positionto insure that the ejected bobbins will be received in the receptacle Ill. The adjoining ends of the rods 26 and 28 are secured together by supporting couplings 34 and35. 5

- sition after having been displaced therefrom.

The coupling 34 is provided with a cylindrical hole 31' in which the adjoining ends of the rods 26 and 28 are inserted after the bent rods have been threaded into :the hem 22.- The rods are se-- cured in position by set screws 38 which are threaded into the coupling 34 and project into the'opening or hole 31. One end, preferably the upper or forward end of the coupling 34 has formed integrally therewith a ring 40. The ring 40 receives a hook 42 formed as a part of a sup- 35 port 44 fixed to the loom frame I2. The support 44 comprises in addition to the hook 42, a seat 46 having an opening therethrough for receiving a bolt by which the support is secured in position on the loomside. tended toward the right in the-form of a partly cylindrical web 50 of which the hook 42 is a forward extension. The lower portion of the web 50 is extended to form a stop 52 against which the coupling 34 bears when the receptacle is in bobbin receiving position. v

The coupling 36 which is located on the other side of the bag is the same as the-coupling 34 and is provided with :an opening to receive'the adi joining ends of the rods 26 and 28, set screws 54 for maintaining the rods in position, and a supporting ring 56 which receives a depending hook 58 which in turn is supported for swinging movement in a bracket 6!). The bracket 60 in turn rigidly supported on the end of a stub shaft 62 which, as shown most clearly in Fig. 1, is supported by and connected by a coupling 64 to a horizontalstud 65 on which a transferrer 61 is mounted. In some cases, however, the-shaft 65 may be sufliciently long and the coupling 64 and 0 the stub shaft 52 may be eliminated and the support or bracket be mounted directly onthe end of=the shaft 66; Thebracket 60 is generally the form of a' U-shaped castin having a hole 68 in one leg'to receive the shaft 62. A set screw in head 16 engaging a spacing collar"!!! which forms 70 a bearing for the upper closed end 80 of the hook 58. Rearward swinging movement of the book 58 is limited by a stop 82 formed integrally with the bracket 60.

It is evident from the above that the receptacle The support then is ex- 40 i0 is positively supported on two sides. As shown most clearly in Figs. 2 and 4, the supporting couplings 34 and 36 are offset relatively to each other to cause the bag or receptacle l0 normally to hang in bobbin receiving position. This is accomplished by locating one of the couplings near the front of the receptacle and by so locating the support for the other coupling, that said support tends normally to urge the bag [0 into a rearward position. Thus, if the bag is displaced forwardly for any reason, the bag or receptacle will swing rearwardly when the displacing force is released.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent of the United States is:
