WERT-RRPLENISHNG LOOM.

Specification of Letters Patent.

Application filed March 24, 1909. Serial No'. 485,402.

Lawrence. in the county of EsseX and State' of Massachusetts, have invented certain new andfuseful Imprm'ements in Vtfeft-Replenishing Looms, otl which the following is a Specification.

My invention relates to weft replenishing looms, and particularly to that class of weft replenishing looms` which have a stationary magazine with aplurality of guide-ways Or compartments for bobbins or filling carriers, and in which, when the lowest hobhin in a ,con'ipartment is released, it drops down to an opening at the lower end of the magazine,

ordinarily common to all the compartments, and into a position under the transferrer, to be engaged hy the transferrer, on the operation of the weft roplenishing mechanism, to he transferred into the active shuttle, to take the place of the substantially exhausted hohhin therein.

It has heen found in practice that when a bobbinis released from the lowerend of its compartment, to drop down to the discharging end ot' the magazine. that sometimes the hohhin is msplacedand does not fall into its proper position at. the discharging end of the magazine under the transferrer, for instance, the head oi the hohhin being heavier than the tip, may reach its proper position under the transfcrrer. but. the tip of the hobbin may be held, or lag hehind on itsI way to the discharging end of the magazine, and not reach its proper position under the transfcrrer arm,

when said arm operates to transfer the hohhin into the shuttle, and consequently the hobbin is nottransferred. y

he ohject of my invention 1s to provide mechanism for properly positioning a bohbin, at'ter it has been released from its compartment, and preparatory to its being transferred into the active shuttle, and my invention consists in certain novel features of construction of my improvements, as will b hereinafter fullyfdescribed.

l have shown in the drawing a detached portion of a stationary magezine of a weft replenishing loom, of the typev shown and described in the pending application for Let.- ters Patent, Serial No. 298,939, but it will be-understood that my improvements may be used in connection with any type of station-` ary magazines, having a. lurality of compartments for bobbins or filling carriers.'

Referring to the drawing :-Figure 1 is a front sectional view of a stationary maga-- zine, and ot the transferring mechanism', taken on line 1, 1, Fig. 2-, looking in the direction of arrow a, same figure. Fig. 2 is a plan view oi' the parts shown in Fig. 1, showing a. section, On line 2, 2, Fig. 1, through the magazine; some of the parts shown in Fig. 1 are left O' in this figure.

In the accompanying drawing, 1 is a stand secured to the loom side, notshown, land having secured thereto, in this instance by bolts 2, the side flanges 3 on the rear or inner guide-ways 3', in this instance four in numher, for the hea-ds 4 of the bobbin's 4.'

5, see Fig. 2, are the lower parts of the outer guide-ways for the tips 4" of the bobbins 4; 6, 6 are `two vupper transverse rods, and 7, T, two lower transverse rods, see F ig. 1, which rods attach the front guide-ways, `or the front part of the magazine to the rear part.

8 is the transitori-er arm carrying the transferrer 8', see Fig. 1, and having its hub pivotally mounted on the stand 1, in the usual way, and having the downwardly extending arm S, on which is pivotally mounted the bunter 9, having the downwardly extending arm 9- with a stud 9 thereon, which is engaged the hooked end of a. link 10, pivotally mounted on the lower end of the downwardly extending arm 11 Patented Oct. 12, 1909.A i

of the fansferring mechanism, which has l its huh 11 mounted on a. stud 12 on the stand 1, see Fig. 2. Extending out from the hub 11 is an arm 13, which is connected with the transferrer operating mechanism,

not shown.

A helically coiled torsion spring 111i, cOn-' tion, shown by broken lines, engages `said.`

bunter on the forward movement of the lay, to operate the transferrer mechanism.

16 are rocking supports or cradles, adapt ed to retain the bobbins in .their compartments, and on the rocking' thereof to drop a-selected boh'bin to the discharging end of the magazine. which in this inzstance is cour mon to all of the, conn'iartnients, and toward Which the bobbins drop by gravity.

All of the above mentioned parts may be ot' the usual and well known construction in the class ot' looms referred to.

l will now describe my improvements, which as above stated consisthof means for properly positioning the selected bobbin or illingg` carrier.l which is released from its compartment, preparatory to beine,V trans i'erred, in case said bobliin i5 aiiaplaeefcl, or fails to properly drop to the disclrarging` end oi the magazine and below the transfer-rer arni 8. l have shown in this instance my positioning means located at the 'front part, ol the magazine, and intended to engage the tip eral of the bobbins orlilline carriera. l
