T aZZ whom it may; concern: 4

Be it known that I, EPPA H. troN, e citi- :aen of the v United States, residmg at lveltham, in the county or" Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Weft- Replenishing Looms, of which the following is a specification.

My invention relates to Weft replenishing looms, and particularly to enelectricfilling detector or fceler mechanism for automatic Weft replenishing looms, to, detect the substential or practical exhaustion of filling in. the active shuttle "and put into operation the weft replenishing) mechanism to supply fresh filling.

The object of my invention is to simplify and improve upon the construction of electric filling detector or feeler mechanism for weft replenishing looms.

My invention consists in certain novel featuresoi't construction of my improvements as Will he hereinafter fully described.

Iln my improved construction of electric filling detector or feeler mechanism, It pro vide a feeler dev1ce' comprising two members, one preferably in the form oi a slide,

shit-ably guided ins stand, and having an end adopted to enter through an opening in in the normal operation of the loom.

In case the filling on the bobbin is sub stsntially exhaust/ed, theerigegeme it of the inner ,engagin end of said plunger with the denuded bobbin, will force outwardly said plunger, and, through intermediate come ition close the electric circuit, which is normolly open, and put into operation the Weft replenishing mechanism to supply fresh iiii ing to the active shuttle, all as will he hereinsfter fully described.

I have shown in the drawings detached portions. of. a loom, and particularly the Specification of Letters Eetent.

Fig. '8 is a partial section and side View of the parts shown in Fig. 3. looking in the direction of arrow at, same figure, with some ofthe parts left oh, and. Fig. '2 to Fig. 6, lout shows the position of the feeler slide before the iey heats up, and as the feeler enters the shuttleto engage the filling.

In the accompanying drawings, 1 is a stand secured to the loom side, not shown, 2 is a detached portion of the stationary magazine secured to and supported on the stand '1. The filling detector or feeler stand 3, is secured to the stand 1 by bolts 3. The stand 3 carries e stud 4 having it bushing5 thereon, secured by a out 5, adjustcorrespdnds figure. Fig. is a sectional plan View, taken on line 3, 8, Fig. 1, looking "ably secured to the :teeler bed 7, which is securederr'the bushing 5 by ascrew bolt 8 in shown in Figs. 3 and 4:), which cap is sea stud 16 on end of the angle lever 15 carries a copper cured to the feeler bed 7 by bolts 10. Within the cap 10 extends a rod 11, having a screw threaded end 11, which is adapted to engage a threaded ,hole in the inner end of the cap 10, to be turned in or out in said hole, see Figs. 6 and 7. On'the rod 11 is a helically coiled compression spring 12, which bears at one end against the outer end of the cap 10, and at its other end against a lug 9 fast on the cover 9, secured on the top of the slide member 9, to move with said slide member. The spring 12 acts to hold the slide member 9 in its forward position, as

shown in Fig. 7, until, on the forward movement of the lay, said slide is moved outwardly, by engagement of 'lthe bobbin with the inner engaging end thereof, as shown in Fig. 6.

The second member of the filling detector mechanism consists in this instance of a plunger 13, which is loosely mounted to have a longitudinal movement in a groove or recess in the slide 9, see Figs. 3 and 4. The inner engaging end of said plunger 13 is preferably made wedge shaped, and is adapted to extend beyond the inner end of the fecler slide 9 and enter between the coils of the filling on the bobbin, on the forward beat of the lay, as shown in Fig. 3. The other end of the feeler plunger 13 is screw threaded, and has thereon a check nut 14, which maybe turned in either direction on said plunger 13, and engages at one end with the wall of the slide member 9, as shown in Fig. 3, to limit the outward movement of the plunger 13. The distance that the engaging end of the plunger 13 extends beyond the engaging end of the slide 9, may be regulated by turning the nut 14 on the screw threaded end of said plunger 13.

A helically coiled compression spring 15 extends and is supported between 2. lug 9 on the slide member 9, and one arm 15 of an angle lever 15. The spring 15 acts to yieldingly hold the end 15' of the angle lever 15 against the check nut 14, on the plunger 13, and move outwardly said plunger 13, and yieldingly hold it in its outward position as long as there is any substantial amount of filling on the bobbin, as shown in Fig. 3.

The angle lever 15 is pivotally mounted on the feeler slide 9. The inner plug 15", which is adapted to engage with the inner end of a strip of metal 17, which strip of metal is secured in a groove or re 1 cess in a strip of insulating material 17" secured within the recess in the slide 9, as shown in Fig. 5. The outer end of the strip 17 is connected by means of a wire 18, see Fig. l, with a battery 19. An insulating strip 20 is secured upon the outer side of the strip 17 at its outer end, as shown in Figs. 3 and 4, to prevent said strip 17' from coming causing said against the filling on the bobbin,

in contact with the outer end of the feeler slide 9. To the outer end of the feeler slide 9 is secured one end of a wire or electric connector 21; the other end of said connector 21 is connected with a magnet 22, supported on the shaft 25, and has one end secured to the bearing 3", and the other end secured to a collar 27 fast on the shaft 25. On one end of the shaft 25is secured the hub 28 of an upright lever 28. The upper end of the lever 28 haspivotally connected thereto a horizontally and longitudinally moving rod 29, which is loosely guided in a stand 3.

When the angle lever 15 is moved on its pivotal support, through the inward movement of the plunger 13 .by reason of said plunger engaging with the denuded bobbin, as shown in Fig. 4, and engages the metal strip 17, it closes the circuit and causes the energizing o the magnet. The energizing of the magnet will cause the upright lever 28 tobe moved inwardly, against the action of the torsion spring 26, andfrom the position shown by broken lines to the position shown by full lines in Fig. 2.

The inward movement of the. upright lever 28 will move inwardly the rod 29, rod: to extend into an open or slotted portion 3 in the stand 3, and form a fulcrum for 30, which receives its motion; from a cam, not shown, through a connector 31, which is provided with a rod head 31' thereon. Piv- .otally connected to the outer end of the lever 30 is a rod head 32' on the lower end the end of the operating lever of an upwardly extending rodor connector 7 32, which is connected with and operates the selecting mechanism of the weft replenishing mechanism. as fully shown and. described in U. S. Letters Patent, No. 1,030,748, of June 25, 1912.

The advantages of my improvements will be readily appreciated by those skilled in the art. They can matic weft-replenishing looms of the type referred to, and by means of the filling detector mechanism, conprising two members, one having a broad engaging edge to bear and the other a wedge'shaped-adjustable engaging end to enter between the coils of filling on be readily applied to auto.

the bobbin, until the bobbin is substantially denuded, I am enabled to allow the bobbin to remain in the shuttle until substantially all of the filling is drawn ofi' therefrom, and then. through the movement of the plunger member relative to the slide member, the electric circuit is closed, and the 'weft, re-

plenishing mechanism put into operation, to

nice

transfer a new bobbin into the active shuttle, all as will be readily understood by those skilled in the art.

It will be understood that the details of chnstruction of my improvements may be varied if desired.
