To all whom 'it 'may coneern:

Be it known that I, llonxcn 'YMAN, a citizen of the United State residing,r at lvorcester, in the county of 'orcehter and State of Maesachusetts. have invented cci'- tain new and useful improvements iu 'etlexhausted bobbin in said shuttle, and my in-- Ventron particularly relates to a upplemental attachment, to be combined with the transferrin; r niechanisimto position a shuttle under the dim-harging cud of the magazine, when the transferring mechanism is to he operated, preparatory to the transfer of a bobbm from the magazine into the activeshuttle. v

The object of my invention is to provide a shuttle positioning mechanin'm of simple construction and operation, and ha vingr that part ofl the mechanism which engages the shuttle mounted on'a'nd movable with the lay, and preferably located hack' of the racevay of the lay, at the inner end of the l.shuttle box.

My invention consists in certain novel features of construct-ion of my improvements as will be hereinafter fully described.

I have only shown in the drawings a detached part of the magazine or weft replenishingr enclof a loom, anda stationa ry magazine, and a part of the tranferring mechanism, with my improvements combined therewith, sufficient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the' drawingz-Figure 1 'is an inner side view ot' a stationary magazine or filling carrier, and the tranet'errilip.r mechanism, and a sectional View through the breast-b aun and lay-beam, oirliue l, l.

l"iom the aleove description in connection with th" drawings, the operation of my iniproveinents will he. readily nnderstotxl by those skilled in the art.

ln the normal operation of the loom my shiut le positioning mechanism will be in the l. L', and 5, bnt in ease ot' the operation of the. filling indicatiovenient of the transl'errer mechanism to transfer a, ltohliin 'rom thel magazine into the active shittt-lc, the rocking ot' the hnh 1l', through arm 2t) and connector 12:5, will move the arm 24", and the. pawl 24. to carry the pawl '3l downlie inelined engaging end 24" thereon, as the la v moves forward, to engage the arm 3U. and rotate the. hub 99 irot stnd It', and move the lever 29 inner end ol the shuttle S, and in the sluitthhhox i'. we lt'ig. Ll, .e transfer ol' a hohhin from the magazine into the shuttle, to take the place of tho practieally exhausted hobhin in thc shuttle. .\ftei" the transfer of the bol)- hit. from the magazine into the shuttle, the' ret urn of the parts o1' theA transtia'riiig moelianistii to their normal position. will move, through the connections tothe pawl ill, Said' pa w1 out ot' eng; 'enient with and out 0f the path ot' tht` lever 25"'. and allow the spring 25'.' to act to retnrii said lever 30 and the slnntte positioning lever '29, to their normal positite-s. ont ot' the. path ol the, shuttle, as shown Fig. 5. lnease. the shnttlo should fail lo enter the .shuttle-linx snliiciently to permit the positioning lever to contact with the end of the shuttle, hat, instead contact. with the. inner side. of the Shuttle, When the pawl 2l is. engaged with the lever 30 on the forward heat ol the. lay, the, lever heing so far helow. the fnlernm Q5 of the pawl 2i. the eoil spring on the hub of the against the. posttiuti il preparatory to tl in 15 on thc upper end of the slot 16 in the plate lt. wili yield, and the pin 15 will he moved downward in the slot 16' and the engaging end 24 of the pawl 24 will pass h v the end of said lever 30 as the lay moves to its forward position, leaving said lever 30 in its normal position, shown in Fig. 5, and preventing any breakage of the parts.

ln my improvements in looms, having a la y, and a shuttle, and a positioning device for the shuttle carried on the lay, I make provisions fot' a elear and an tinobstrnctive spat-e hetween the breast beam, and the raceay of the lay, and the inner end of the shuttle. for the filling thread to pass from the shuttle to the fell of the elotlff'and also to remove or replace the shuttle by lmhff, hv placing the gxisitioning devic behind the shuttle and near its inner end, and I move ported on the rear side of the lay, and nornmlly in :in inoperative position, u Li'nnsfcrrer lover. and connections intermediate said lover und said positioning device, whereby upon nn indication of the rieur exhaustion of fiiling in the act-ive shuttle, the transfcrrcr will be actuated, and an arm of the shuttle positioning device moved around to I therein.
