J. NORTH ROP FEELER LOOM Filed May 26, 1917 on the front of the loom and extonds trans wrsely thereof. hen the filling lovlor merhanism indicates ihat the running' filling has approached the point of prmlvtorminml 5 or critiwal exhaustion. the rock shaft 8 is turned in a clockwise direction. viewing Fig. 1, so that. on the next suvcomling: or ivplvnishing heat-up of the lay tho c'rilii-ally on .hausled bobbin 9 may he forced out of tlw shuttle ll) and a filled hobliin he lllHi'l'Pll in its place. As the lay heats up on ils 1iplenishing heat. the usual fovhz ilii'eml parrer, located near the replenishing mmhrv nism. engages the filling enil extvniling fromhe selvage to the outgoing: llfillilln :m l severs it.

The hohhin chute 14 is pivoially mounted so that it may he liked into and out oi open utive position undet'the i'eplmiishing slmti kbox 12. During regular weaving the tilting bobbin ohute is held in ino 'ioralivu pmii'am. as shown in dotted lines in Fig. 1. and on the indication of prmiitm'minerl exhaustion of the to mining; filling. the i'rfliirhlrl rrhutv is tilml regu'wll'dly into operative position so as to be under the replenishing shultlo how .23. on the next forward heat of the. lay hon aha replenishing operaiion takes plane. The op emtive positionof the bobbin (hlltt is shown in full iines in Fig. l, and is vlotvrmineil by a. stop lug 13. The ijiobnin chute is loosu 3* mounted for its tilting movements on a stud 15 ext-ending outwardly from ihf' end ll, of a bracket 1? adjnstably secured by means of a bolt 18 to the loom frame 19.

The bobbin chute rereivss ils ai'mation into and out of operative position from fia rock shaft 8. The connections lWlTVKIH tin;-

Tb rre'upon the ill ing fore that there is no attempt of the parts to pull the filling and out of the shuttle while the shuttle still remains in the shuttle box, excegt); by the action of the descending bobbin; ependence is first placed on the feliing bobbin to extract the filling and from the shuttle, and if this fails. then the cooperative action between the tilting bobbin chute and the thread book successfully completes the thread extraction, effectually preventing the outgoing filling end from being drawn into the sbed.

The preferred form in which it is contemplated embodying the invention has described in the foregoing specifica- Zion and illustrated in the accompanying drawings. It will be understood, however, that the invention may be embodied in other forms than that shown and described, without nartim: from the spirit or the followi laims.
