- is to provide such needles withmeans to detect the abnormal position of warp threads said means being actuated by such warp threads, and in conjunction with weft stop devices, operate to stop the loom.

A further object of my invention is to provide-such needles with means to engage with and disengageirom needle operating mech' anism, said means being engaged with such operating mechanism when the-needle rests in the line of travel of the said operating mechanism, and a further-object is to pro vide the needle with means to resist acci'-- dental misplacement when being carried out of the line of travel of the operatingmechanism.- l attain this object by mechanism shown in the accompanying drawings, in which,

Figure 1 is a view in side elevation, broken to save space, and broken out to ,show de' tails of construction, of a weft inserting. Fig. 2,1s.

needle embodying my invention. a plan view of the parts shown in Fig. 1. Fig. 3 is a view in vertical cross section on the line 33 of Fig. 1, looking in the direction. of the arrows, this view showing a convenient and preferred cross sectional construction of a nee le. f

The needle is-indicated by letter A. l or the purpose of securing rigidity and lightness the needle in cross section has the form of a Greek cross, although other cross sectional forms, which will serve to attain the desired lightness and rigidity, may be employed. The butt end of the needle is provided with a pin, 0, which is designed to be engaged by a picker, or other mechanism, to

insert, and withdraw the needle 'from "the when not in active contact with t e actuatmg mechanism, Near the forward or pointserves to keep the needle from accidental mis lfacement,

end of the needle a vertical mortise'd is out, and there. isprovided also a thread tie-- livering eye, 0, which passes through the needle, from front to back .and intersects the aforesaid vertical mortise. ()n a pin f at the end of the mortise farthest from the thread delivering eye is pivoted a detector 9, moving in a vertical plane. The free end of this detector crosses the line of travel of the weft thread in its movement through the delivering eye, and such free end is pro its outer side and projects slightly above the lines of the needle. A spring a secured in the mortise, d, engages and holds the de tector in its elevated position, and normally preventsthe detector from interfering with the passage of the weft through the delivering eye.

As is well known, upon the occurrence of a float in the warps, the warp shed is conpositioned ,w'arp threads would bear upon the exposed surface of the detector 9 and depress the free end of the same within the mortise, so that the cuttingedge h would sever the weft, and free, it from its tension,

any suitable nature, would respond to the action of the slackened weft, and stop the loom, The needles, if carried in a series of boxes inlieu of shuttles, would as the shuttle box shifting mechanism shifted the boxes, be brought into the line of travel of the picker and the pin 0 would be engaged slide within its box and project its end between the warp shed; as the needle was shifted away, from contacting with the picker, the spring 6 would hold the needle 111 an assumed position during the inactivity of the needle. I

Having described my invention, I claim S new, and desire to secure Letters Patent 1. In a loom, a filling insertin needle provided with means .to engage wit I and disengage from its actuating means and .a yield abledevice upon the'needle to hold-the needle in a predetermined position when-not in operation.
