ALONZO E. RHOADES, OE HbI EDAIiE, MASSACHUSETTS, ASSIGNOR TO DRA PER CODI- IPANY, or HOPEDALE, MAssacrrUsErrs, A conrom'rron or MAINE.

Be it known that I, AnoNzo E. Rnoanns,

I a citizen of the United" States, and resident of-Hopedale, county of Worcester, State of :Ma'ssachusetts, have invented an Improve: l ment I m- Filling-Carriers for Automatic eeler-Looms, of which the following de- Jj'scription, in connection with the accompanymg drawing, is a specification, like charac- .1-0

ters on the drawing representing like parts.

ThlS inventlon, which is a division of an application Serial No. 588,411 filed by me the 22nd day of October, 1910, has for its objecttheproduction of a novel form of filling-carrier or bobbin more particularly adapted for use in connection with a loom equipped .iwith filling-exhaustion. indicating mechanism of the type shown and described in my above-mentioned application.

The filling-carrier forming the subject-mat- I ter of this application has its barrel provided witha plurality ofseries of axially-arranged depressions, the depressions of one series being arranged opposite the spaces between the do pressions of the other series. When such a I filling-carrier is properly mounted\in the shuttle of the loom one series of the depres- -sions will beopposite each impinging portion of the feeler of the filling-exhaustion 111- dicating mechanism on each feeling. pick, so that when the filling is woven ofl to expose the depressions one or the other of the impinging portions of the feeler will enter a depression and cause the feeler to swing laterally into abnormal position.

In order that the cooperation of the feeler I with the filling-carrier may be properly understood I have herein illustrated a sufficient I portion of the feelermechanism as will suffice for the purpose.

Figure 1 1s a side elevation of a fillingcarrier or bObbln embodying my pnesent invention, showing clearly the pluralityof se- 'ries of axially-arranged depressions 1n the barrel of the carrier; Fig. 2 is a dt'ail view in plan of the feeler and some of its ad-.

juncts, with which the filling-carrier is designed to cooperate, to illustrate the manner in which functional movement of the actuator is effected when the feeler 1S abnor- 'mally positioned by coiiperation with the filling-carrier, the latter being shown partly in section.

head of the removable filling-carrier-or bobbin 0, the side wall of the shuttle toward the front of the loom having an elongated slot D through which'the feeler can enter the shuttle.

The elongated and cylindrical barrel 1 of the filling-carrier, Figs. 1 and,2, is herein shown as provided with two series of axially-arranged depressions 2, 1 ,.*the de ressions being longitudinally extended an entering quite deeply into the wood of the barrel, Fig. 2. I

The depressions 2 are separated by ribs 3, while similar ribs alternate with the depressions 4, and I preferably make the depressions considerably wider than the thickness of the intervening ribs at the surface of the barrel. I I a It will be seen that the depressions of one series are staggered with relation to the depressions of the other series. That is, a depression 2 is arrangedwith its longitudinal center opposite to the rib 3 between two of the depressions 4, and vice versa, so that no positioning of the filling-carrier in the shuttle can bring a rib of one series in alinement with a rib of the other series, nor can depressions of the two series be alined. This is important in connection with the feeler mechanism in connection with which the filling. carrier is particularly adapted for use.

Referring now to Fig. 2 the feeler support or carrier E is in practice mounted to slide back and forth in a suitable stand, as in my co-pending application, in a manner wellknown in the art, and an actuator I, J, is pivoted at H on the carrier E, the free end of the arm I being turned rearwardly to enter the slot D of the shuttle opposite the adjacent spring-jaw B, the longer arm J of the actuator being extended frontward. In practice the arm J is arranged to cooperate at times with a device which governs the operation of the filling-replenishing mechanism and forming no part of this invention. Normally the autuator arm I is held against a stoplug 5 on the carrier E, and at such time the actuator'as a whole is inoperative, the functional or active movement of the actuator to bring about filling replenishment being efi'ected when said actuator is swung about its pivot H into the position shown .in Fig. 2, due eng'a ement of the free end of the arm I with t e spring-jaw B. Such engagement is controlled as to the t1me of.-1ts occurrence by the feeler 9 piv oted at 10 on a prolongation-bf the carrier E and adapted to swing in allaterallane at one side of the actuatorarm Iiihe.pro-

jecting rear portion of the feeler is bifurcated to present two alined and laterally separated impinging ortions 11 11"equidistant from the fulcriim ivot 10 Swing- I ing of the feeler is limited y a pin 12 oncthe :carrier E, which enters a segmental notch 13 in the front edge of the feeler. So long as both portions 11 oftthe feeler impinge upon the filling in the shuttle on the beat-up o thelay on the feeling stroke-there will be no pivotalmovement of the feeler, and the feeher and its carrier E will be moved forpinging portions 11- are not-pressed upon- Ward as a unit on the beat-up. When, however, the filling weaves ofi so that the imequallyand simultaneously on ;th'e feeling stroke the feeler? willswing on its pivot l O in oneon theother direction, permitting the actuatozrfarn to impinge upon and be moved by fthe jaw B before the forward stroke of the feeler carrier Ebegins.

In Fig. 2 it issupposed that the filling has been exhausted" to the small portion T, both 7 series of depressions 2and 4 1n the barrel of the filling-carrier 'being exposed. As the lay advances on the feeling pick the left hand impinging portion 11 of the feeler engages one of the ribs 3 between two of the depres sions 2 while the right portionll is opposite a depression 4, and manifestly the" tive position. The functional movement of feeler will. be swung on its pivot 10 as shown, thereby permitting the free end of the actuator arm Ito impinge upon the jaw B, so that the actuator is swung into operathe actuator so effected will cause its arm J on the forward stroke of the carrier E as the lay beats up, to act upon suitable intervening devices, (not shown) and bring about the actuation of the filling-replenishing mechanism in a well known manner. The

depressions in the filling-carrier permit a very considerable swinging movement of ing a plurality of series of depressions, staggered oroflset. with relationto each other, will be obvious, for no posible position of the filling-carrier in the shuttle can fail to locate a depression of oneor the other tions 11 of the feeler. Hence when the filling weaves off to exposev the depressions the' feeler will be swung-on its pivot in one or the other direction to bring about the deof the feeler mechanism.
