SPECIFICATION formingrpart of team. Patent No. eaasri, dated mg, 18, 1899.

Be it known that I, ARTHUR W.-BEABDsELL-,

of Milford, county of Worcester, State of Massachusetts, have invented an Improvementin Looms, of which the following description, in connection with the accompanying drawings,

is a specification, like letters and figureson the drawings representing like parts.

This invention relates more especially to looms provided with automatic filling-supplying mechanism, whereby the shuttle is provided with afresh supply of filling upon the more or less complete exhaustion of the previous supply or upon its breakage. I

My present'invention has for one of its objects the productionof means for controlling the filling-supplying mechanism through two different and independent sets ofdevices,the one operative upon failure of the filling and the other operative upon the exhaustionof the filling in t-heshuttle to a predetermined extent. I

The loom is provided with stopping means which will be automatically operated upona second failure ot'ffilling to thereby stop the loom, whereas if the filling-supplying mechr anism'is actuated-upon the exhaustion of the filling to a predetermined extent, said stop.-

, ping means will be held inoperativeunless a misthread should occur.

I have herein shown a sufficient portion of the fillin g-su pplyin g mechanism to he under-1 stood as substantially that shown 'in'Un-ited V V States Patent No. 529,940, dated November 27, 1894, to which reference may be had.

ing mechanism will be located at one end of will besupposed that the filling-supplythe layythe latter beingcut away atthe adja- Q cent shuttle-box to permit the passage there- 'th rough of the ejected-filling carrier from the shuttle, as in the United States patent referred to, said filling-supplying mechanism comprising, essentially, a feeder or hopper F, Fig. 2, and thetransferrerf, (see dottedlines, Fig. 2,)n1jounted on the stud f and actuated substantially as set forth in said Patent No. 529,940 to transfer a fresh-filling carrier from the feeder to the shuttle at the proper time.

' Referring now to Fig. 1, the front plate 13 of the-shuttle-box at the left-hand end of the lay A is provided with an upturned bracket 22, on which is pivotally mounted a feelen carrier, shown as an arm I), extended-longitudinally inthe direction of thelength of the lay and weighted at its outer endat b the opposite or'inner endof the aim being bent to a form a dog b ,'whi1e the weighted end of the feeler-carrier has attached thereto the filling 'feel'er b shown as a substantially (l-shaped j member, the free'endofwhichis' preferably enlarged to rest fupon the fillingfein the shuttle- S-when the latter is in the shuttle-box. As the-diameter of the mass of filling decreases the 'filling-feeler will ateach beat-up oft-he lay extend further in toward the longitudinal center of the shuttle due 3130 the weighted end b er the fee1er=carrier,and

thereby the opposite end or dog-b will be elevated. r

Inasmuch as the; filling-feeler' must beremoved from the pathof the' shuttle as the'latt'eris thrown, I have provided a litter, shown as a cam b formed on the outer end of .an arm b rigidly securedftothe frame 'A ofthe loom'and extended forwardly in such position that as the lay goes back the. lifter b willpass beneathlhe weighted end of the feeler-carrier, and the inclined face of the cam'will lift said-arm and the'feeler as the lay reaches its rearmostposition, so that-the feelerwill he entirelyout ot' th'e way of the shuttle."

f The usual shipper-handle S (shown inl ig. 1) moves inthe notched holding-platens", and a knock off lever b, which normally restsagainst or adjacent the shippenhahdle, is pivon the breast-beam A and provided with a guideway, in which a slide b is adapted to reciprocate, said slide having pivoted at 71 a filling-fork b, the fork having a rearwardlyprojecting tail I), (best shown in Fig. 4,) adapted to be engaged by a hook I), pivotally mounted on the upper end of the slideactuator or weft-hammer A when the filling is absent as the lay beats up. A latch 61 is? pivoted at (Z on the slide b said latch having on its under side a cam 12, the free downturned end of the latch being adapted to at times operate the knock-off lever b, a pin or stud d herein shown as mounted on the stand 19 having its upper end inturned, as at 14, (see dotted lines, Fig. 3,) to extend beneath and cooperate with the latch-cam 12. Back of the cam 12 the latch is recessed in its side,

as at 40, Fig. 4., to receive the inturned end- 14 of the pin d when the slide I) has been moved outwardly.

On the outer side of the slide 11 I have mounted a rockingv bunter m, pivoting it for convenience on the weft-fork pivot b said hunter having a forwardly-extended finger m, which is normally held by the weight of the depending bunter against one end of an S-shaped arm or detent n, pivoted at n on the slide, the other upturned end of the de-,

' tent being notched or recessed to form ashoulder 113.

The tail 1) of the filling-fork forms one connection between the weft-ham mer A and the slide bf, the position of said tail or connection being determined by the presence or absence of filling in the shed as the lay comes forward;

but in addition to this connection I have pro vided an independent connection between the slide and the weft-fork, shown as an out- Wardly-eXtended loop-like catch 0, preferably of stout'or heavy wire, with its ends outturned to form pivots, which enter holes in the slide, the catch 0, as shown in Fig. 3, being made wide enough to prevent interference with the weft-fork tail 12 One pivot end of the catch, as O, is extended beyond the side ofthe slide and is bent forward to form an arm 0 outside of the S-shaped detent a, said arm at its free end being up turned and bent inward, as at 0 to be normally engaged by the shoulder a of the detent, as shown clearly in Figs. 3 and 4. A weight 0 is secured to the arm 0 near its free end to prevent disengagement of the end of said arm and the detent by the jarring of the loom or other accidental cause.

The lower extremity of the bu nter m is normallyabovc the path of movement of the dog Z2 as the latter comes forward when the lay beats up; but as the filling in the shuttle diminishes the dog is gradually elevated until when the filling has been exhausted to a predetermined amount the said dog will be elevated sufliciently to engage the depending end of the bunter on the forward movement of the lay, swinging the hunter to the right, Fig. 4, and thereby rocking the S-shaped detent n to withdraw the shoulder n from the overhanging part 0 of the catch 0. Thisdisengagement permits the weight o to drop, and thereby turns the catch 0 on its pivot into position to be engaged by the hook of the wefthammer or actuator, so that on the next outward movement of the latter the slide 12 will be moved outwardly, and its outer end will at such time engage an upturned arm (Z fast on the rock-shaft d, turning the latter sufficiently to operate the filling-supplyingmechanism in well-known manner to thereby insert a fresh supply of filling into the shuttle before complete exhaustion of the filling then in the shuttle. When the shuttle enters the box at the right-hand end of thelay, the feeler will dip down in the empty shuttle-box sufiiciently to raise the dog above the depending end of the hunter m, the said hunter, as best shown in Figs. 2 and 4, being rearwardly ,curved to leave a clear space between its pivotal pointand its depending end, so that when the dog is elevated by'the descent of the filling-feeler into the empty shuttle-box said dog will enter the clear space between the ends of the hunter and will not engage the latter. When the filling fails, however, the fork h will not be tilted, and its tail 19 will be engaged by the book of the actuator A to thereby move the fork-slide outwardly, such outward movement of the slide disengaging the cam 12 of the latch d from the end 14 of the stud or pin d, and the latch will drop behind the knock-offlever 19 and stop the loom before there has been a thin place or streak made in the cloth. On the inward movement of the slide the cam 12 rides up .over the end 14 of the pin, and thus raises the latch into normal position.

hen the filling-feeler is niade operative to elfect a change of filling, the loom must not be stopped unless there be a misthread,

and in the latter case the filling will not be laid in the shed, and the filling-fork will then operate as before described, and the loom will be stopped before the formation of a thin place in the cloth. It is thus necessary to prevent stopping of the loom on the outward movement of the slide 5 when the fillingsupplying mechanism is operated by or through the feeler-governed mechanism, and to prevent such stoppage I have herein provided a trip to engage and prevent movement of the latch (1 into operative position, so that instead of stopping the loom on the outward movement of the fork-slide the filling-supplying mechanism will be operated.

The latch is provided witha laterally-extended pin (Z adapted to be engaged by the IIO eaten n I trip 6, shown as a plate mounted on theside of the slide 1) by means of a headed pine", extended through an inclined slot in the plate, 'sothatwhen the latter is moved to the right, viewing Fig. 4, it will also move upwardly and into position 'to engage'the stud d to thereby prevent the outer end of the latch from descending sufficiently to engage the knock-0E lever b. The trip 0 is connected by a link with a bell-crank lever 0 pivoted at c on the slide b the oppositearm of said lever being connected by a link 0 with the depending weight o 'on the arm 0 of theca'tch.

- When the catch 0 is released, as has been described, and swings downward, the bell-crank I lever will be swung on its pivot to move the link e in the direction of the arrowBO, Fig, i I 4, to thereby move the trip into the operative.

position described.

I have provided means to automatically set the catch oafter it has been released by the' detent, saidsetting device being shownas a weighted arm h, pivoted at h to the slidestand b and having'its upper end oppositely beveled, as at-3. Snpposingthe catch to have been released, the weight 0?. will wipe over the upper end of the arm h on the outward movement of theslide rocking said 'arm to permit such passagmvbntionthe return or inward movement of the slide the rocking of thearm h is limitedby a'pin h so that the l weight must ride upover the beveled end of;

the arm, and as it issolifted itrestores the part 0 of the catch to itsposition on the shoulder-n of the detent. '7 I v The controlling means for the fillingsup plying mechanism includes for the purposes v of this present invention the slide b the arm n (1 and rock-shaft d, and the usual connections between said rock-shaftand-the trans- "ferrer', substantiallyas in the Patent-No..

52 9, 940 referredto', and this controllin'g'me ans his governedfbythefilli-ng fork and cooperating devices or by thelfilling-feeler and its co-, operatingdev-ices hereinbefore described. V

Itwill bemanifest that if the fresh'supply of filling is placed in the shuttle uponthe ex- I ,haustionof the previous-supply of filling to a predetermincdeXtent the filling-fork will operate in usual manner should there be a 'misthread, andthe loom will. be stopped by 5 the outward movementzof the slide, as the 'f'trip cis then in normal position, just as is the case when afilling fails;

' Neitherset'ofdevices for governing th'e'controlling means for the filling-supplyingmechanisin interferes with theother, bnteach opcrates properly withinits own bounds.
