, oi the final I The feeler sion of the beat of the lay. When the lay again recedes,

the spring L, restores the feelers G, and H, to their normal rearward position. In addition to this reciprocating movement which the primary :feeler H, has in common with the secondary feeler G, it has an independent movement of its own. H, reciprocates with respect to the'ieeler G. The feeler G, surrounds the feeler H, at its rear or feeling end, (Figs. -t-, and 5,) so to furnish a guide therefor. At its torwardend, the tcelcr ll, pivotally connected to the lower arm c, of a lever which ad'ustahly and. pivoially connected at a, to a bracket 6, on the shank J, of the feeler G. This lever has a long forwardly extending arm f, the weight of which tends normally to cause the feeler H, to project rearwardly beyond the feeler Gr, and nearer the weft D, as shown in Figs. 1, 3, and 5.

Vl hen the lay heats forward with the shuttle in the shuttle-box A, at the detecting side of the loom, the Weft D, first comes in contact with the rearwardly projecting primary lecler H, causing it to slide torwardl upon the teeler thereby liftingthe ion hardly earti'znding Weighted arm j, of the lover a, f, as shown in l ig. l and imi'ncdiaiel y thereafter the weft encoun the roaiwerd end of. the secondary teelcr (l, and during the remainder of the forward best i of the lay, both feelers move forwariilly to gether against the st see of the spring L. When the lay retreats, both feelers move rcarwardly together under the stress of the spring L, and the primary feeler H, moves still farther rearwardly on account of the weight of the arm f, of the lever c, f. This action continues until the supply of the weft becomes so far reduced as to demand weft-replenishrncnt. When this critical point is reached, (assuming the auxilii-iry 't'celer l, to be out of action), the prin'iary finger ll, does not come into eil'cc'tivccoir tact with the weft in substantial advance of the secondary Eccler Gr, so that both lcelcrs move forward substantially together and the t'eclcr ll, does not slide upon the icelor G, and mnscqueutly the forwardly extending arm f, starts the well:--i.'cplenishing ll'lQClflZtnism into action. since it n'iainlains its lower most position. The retention of this lowcn most position by the arm f, starts the weft replenishing mechanism. into action, but bctore the controlling mechanism is described attention will he directed" to the peculiar construction of the weft-carrier .l, which permits this concurrently cli'ectz-id movement l of both feelers. licwveltwarrirzr (l, at its portion. which ri-gr' this with the primary tccler H, is {oi-mod with loun'iimlinal grooves or flutes g, as shown in Figs. 8, l and 5, these flntes lining located all the way around the weftspring L, during tie remainder.

.is a lever feelers move forward. with the carrier C, so that one of them is always opposits the primary feeler H. These grooves or flutes are similar in function to those described in. United States Letters Patent of Northrop, No. 686,903, November 19, 1901. When the Weft approaches exhaustion, the primary finger H, (which is thin at its feeling" end) crowds the weft into one of these grooves, (Fig. 5,) so that, finally, the primary linger l-I, does not come in contact with the Weft in substantial advance oi. the finger G, and hence both fingers move forwardly together and there is no independent sliding of the primary i'eoler on the secondary feeler. As alr ady stated, the result of this failure of the primary finger to slide upon the secondary finger is to leave the arm 1", in its normal. lower position, at which time a pin it, (carried by it) rests (Figs. 1, and 3,) upon a controller M, which pivoted at e', to an extension of the breast-beam. The arm f, has a tooth l, on its lower face which, normally, (that is, when the feelers are at rest), is just back of the rear upper corner of a 'ledj e m, on the controller M. When the' we t encounters the primary finger H, in. adiance of the secondary leeler G, during the forward swing of the lay this tooth Z, oil. the arm. f, is ll t'ted above the lodge in, so that said tooth rides forwardly clear above the ledge, as indicated in 4:. 'VVlien, however, due to the approaching exhaustion of the weft, the arm is maintained in its lower position the tooth Z, encounters the lodge in, as the two result that the controller M, is swung on'its pivot-Z.

The controller M, has a short arm 7), which is pivotally connected with a slide 0, which carries a cam r, as shown in Fig. 2. Normally a dagger P, rests upon the high part of this cam r. This dagger P, as shown. in Fig. 8, extends forwardly horizontally above the hreast-heam and is ivotally connected at its forward end witli a vertically extending arm Q, which is secured fast to the rocking change shaft F. Normally, this dagger l, is hold by the cam r, aliovc the path of a vibrating weft hammer .ll, which 'reciprocatcd in the usual way. When, however, the controller M, swung (owing to the tooth Z, encountering the lcrlgc m.) the cam r, is withdrawn. from the dagger l.

'wlicreuprm said dagger drops into the dotted line position shown in Fig. 8, where it is in the path of the vibrating \vcttdiammcr. Accordingly, at its next forward stroke, the wefhhammer encounters the dagger I, moving it forwardly, thereby rocking the ch ange slial't F, and bringing about the Weft-rcplcnishment in a well-known way.

After the replenishment has been effected, a spring; (Fig. 6,) restores the controller M, and the cam slide 0, totlicir normal positions, and the change shaft l with its conhm special fluted weft-carriers or and enter a lluie g, in case a fill loetweet a ll.

heeled-parts are resbored to their normal posiiions in'tlie usual way.

The primary feeler ll, is aclyuslably located aml guided on the secondary leeler G, sothat the rearward projeciion of the primary feeler beyond the seconlery eel can lie regulateil, so as $0 insure correc action. For 'lliis purpose the pivot pin G, for tl elever c, f, is eccenliicolly l on a disk n, which turns williin e bearing '1, on the bracket '9, said lislz clamped in uny position of adjustment Toy the screw boll w, as shown in a The forward lCClPlTOCZIllOIl of llie H, is limited by a stop on the The feeler H, is loose vertically Wllllll E guide the rear end-oi?
